The existing numerical control car equipment comprises a numerical control car, a rack, a clamp, a mechanical arm and a turnover mechanism.

Wherein, one end and the tilting mechanism of numerical control car, arm all install on the rack, and the three-jaw chuck is connected with the other end of arm, and the three-jaw chuck position is relative with numerical control car position.
When the thrust wheel is processed on the existing numerical control car equipment, the flange at one end of the thrust wheel is clamped by the three-jaw chuck, and then the thrust wheel is conveyed to the numerical control car by the mechanical arm. In order to ensure the coaxiality of the two ends of the processed thrust wheel, the thrust wheel and the numerical control vehicle are required to be positioned on the same straight line when the thrust wheel is clamped and sent to the numerical control vehicle. After the numerical control car processes one end of the thrust wheel which is not clamped, the mechanical arm conveys the thrust wheel to the turnover mechanism, the turnover mechanism turns the thrust wheel 180 degrees to enable two ends of the thrust wheel to turn around, the three-jaw chuck clamps the flange of the processed end of the thrust wheel, then the mechanical arm conveys the thrust wheel to the numerical control car, and in order to ensure that the coaxiality of the two ends of the processed thrust wheel is within a qualified standard range (the smaller the coaxiality is, the more standard the processed thrust wheel is), the thrust wheel and the numerical control car still need to be positioned on the same straight line at the moment. And the numerical control car processes the unprocessed end of the thrust wheel to finish the processing of the thrust wheel.
Therefore, when the existing numerical control car equipment is utilized to process the two ends of the thrust wheel, the thrust wheel needs to be turned once, the axis of the thrust wheel and the numerical control car are positioned on the same straight line twice, secondary clamping needs to be carried out on the thrust wheel, the working efficiency can be reduced, errors are easy to generate, coaxiality of the two ends of the machined thrust wheel is large, and the qualified rate is low.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example (b):
as shown in fig. 1 to 3, the thrust wheel machining apparatus provided in the present embodiment includes a first tool assembly 1, a second tool assembly 2, and a clamp 3, where the second tool assembly 2 is disposed opposite to the first tool assembly 1. The clamp 3 is used for clamping on the peripheral wall of the thrust wheel 4 to be machined, and the clamp 3 can be positioned between the first cutter assembly 1 and the second cutter assembly 2, so that the first cutter assembly 1 is opposite to one end of the thrust wheel 4 to be machined clamped by the clamp 3, and the second cutter assembly 2 is opposite to the other end of the thrust wheel 4 to be machined clamped by the clamp 3. Along the axial direction of the thrust wheel 4 to be processed clamped by the clamp 3, the first cutter assembly 1 and the second cutter assembly 2 can be close to or far away from the clamp 3, and the first cutter assembly 1 and the second cutter assembly 2 can rotate relative to the clamp 3 so as to process two ends of the thrust wheel 4 to be processed clamped by the clamp 3.
As shown in fig. 1, when the bogie wheel 4 needs to be machined, the bogie wheel 4 may be held by the jig 3. And then the clamp 3 and the thrust wheel 4 on the clamp 3 are positioned between the first cutter assembly 1 and the second cutter assembly 2 together, meanwhile, one end of the thrust wheel 4 to be processed clamped by the first cutter assembly 1 and the clamp 3 is opposite, and the other end of the thrust wheel 4 to be processed clamped by the second cutter assembly 2 and the clamp 3 is opposite. And then, enabling the first tool assembly 1 and the second tool assembly 2 to be close to the clamp 3 along the axial direction of the thrust wheel 4 to be processed clamped by the clamp 3, and after the first tool assembly 1 and the second tool assembly 2 move to be abutted to the two ends of the thrust wheel 4 to be processed clamped by the clamp 3 respectively, enabling the first tool assembly 1 and the second tool assembly 2 to rotate relative to the clamp 3 respectively, and further processing the two ends of the thrust wheel 4 to be processed in the clamp 3 respectively.
Compared with the prior art, the thrust wheel machining device provided by the embodiment only needs to clamp the thrust wheel 4 by the clamp 3 once, and only needs to enable the first cutter assembly 1 to be opposite to one end of the thrust wheel 4 to be machined clamped by the clamp 3 when the clamp 3 and the thrust wheel 4 are moved between the first cutter assembly 1 and the second cutter assembly 2, so that the second cutter assembly 2 is opposite to the other end of the thrust wheel 4 to be machined clamped by the clamp 3, the two ends of the thrust wheel 4 to be machined can be machined, and the coaxiality of the two ends of the machined thrust wheel 4 can be ensured.
Therefore, when the thrust wheel machining device provided by the embodiment is used for machining the two ends of the thrust wheel 4, the thrust wheel 4 does not need to be clamped for the second time, the working efficiency can be improved, errors can be reduced, the coaxiality of the two ends of the machined thrust wheel 4 is smaller, and the qualification rate of the machined thrust wheel 4 can be improved.
It can be seen that the thrust wheel processingequipment that this embodiment provided has alleviated exist among the prior art when utilizing current numerical control car equipment to process the both ends of thrust wheel 4, the thrust wheel 4 of once need overturn to and twice make the axis of thrust wheel 4 and numerical control car position in the same straight line, lead to carrying out the secondary clamping to thrust wheel 4, not only can reduce work efficiency, still produce the error easily, and then the axiality that leads to the both ends of thrust wheel 4 after the processing is great, the lower technical problem of qualification rate.
In this embodiment, the clamp 3 is a collet chuck, and the clamp 3 is configured to be sleeved on the supporting wheel 4 to be processed and clamp two ends of the supporting wheel 4 to be processed along the circumferential direction of the supporting wheel 4 to be processed.
Wherein, the clamp 3 can adopt the existing collet. Further, the clamp 3 may also be a hydraulic collet.
In the prior art, since the thrust wheel 4 has a flange at a position near the end, the clamp 3 for clamping the thrust wheel 4 on the existing numerical control lathe can only adopt a three-jaw chuck in order to stably clamp the clamp 3 and measure the position of the axis of the clamped thrust wheel 4. In addition, in order to facilitate that the thrust wheel 4 can be located on the same straight line with the numerical control car, and because the three-jaw chuck can clamp one end of the thrust wheel 4 to the axis of the rear three-jaw chuck, that is, the axis of the three-jaw chuck and the axis of the thrust wheel 4 can be located on the same straight line, the axis of the three-jaw chuck and the cutter on the numerical control car in the prior art are usually kept horizontal. However, since the weight of the thrust wheel 4 is generally heavy, the thrust wheel 4 may be tilted when the three-jaw chuck grips the thrust wheel 4. In order to ensure that the thrust wheel 4 can be in the same straight line with the numerical control car, the position of the axis of the thrust wheel 4 is often measured and calculated manually after the thrust wheel 4 is clamped to determine whether the thrust wheel 4 is inclined, so that the labor intensity of workers is increased, and the working efficiency is further reduced.
The clamp 3 provided by this embodiment is a hollow cylindrical structure, and the clamp 3 is used for being sleeved on the thrust wheel 4 to be processed and clamping two ends of the thrust wheel 4 to be processed along the annular direction of the thrust wheel 4 to be processed. Therefore, the clamp 3 provided by the embodiment can be sleeved with the thrust wheel 4 and stably clamp the two ends of the thrust wheel 4, so that the two ends of the clamped thrust wheel 4 are balanced by the clamping force, and the inclination is avoided.
Compared with the prior art, the clamp 3 provided by the embodiment can stably clamp the thrust wheel 4, cannot incline the thrust wheel 4, and does not need to measure whether the thrust wheel 4 is inclined or not after clamping the thrust wheel 4, so that the labor intensity of workers can be reduced and the working efficiency can be further improved.
As shown in fig. 2, 4 and 5, the thrust wheel machining apparatus provided in this embodiment further includes a rotation driving assembly 5 and a support 6, the support 6 is fixed in position and is provided with a through hole on the support 6, and the clamp 3 is rotatably connected in the through hole of the support 6. The rotation driving assembly 5 is connected with the clamp 3, and the rotation driving assembly 5 is used for driving the clamp 3 to rotate in the through hole of the support 6.
Wherein, the clamp 3 and the support 6 can be rotatably connected through a bearing. As shown in fig. 2, one end of the clamp 3 may be exposed out of the seat 6, and the end of the clamp 3 may be provided with a pulley 30. As shown in fig. 2 and 3, the rotation driving assembly 5 may include a rotation motor and a belt. One end of the transmission belt is sleeved on an output shaft of the rotation motor, and the other end of the transmission belt is sleeved on a belt wheel 30 on the clamp 3. The rotation motor can drive the transmission belt to rotate, and the transmission belt can drive the belt wheel 30 and the clamp 3 to rotate, so that the rotation process of the clamp 3 in the support 6 is realized.
As shown in fig. 1 to 3, the thrust wheel machining apparatus provided in this embodiment may further include a frame 7, two alignment driving members 71, and two horizontal driving members 72. Both horizontal driving members 72 are mounted on the frame 7, and an alignment driving member 71 is connected to each output end of the two horizontal driving members 72. One of the alignment drives 71 has an output shaft connected to the first tool assembly 1 for driving the first tool assembly 1 opposite to one of the ends of the bogie wheel 4 to be machined held by the fixture 3. The other alignment drive 71 has an output shaft connected to the second tool assembly 2 for driving the second tool assembly 2 opposite the other end of the thrust wheel 4 to be machined held by the fixture 3. The horizontal driving member 72 is used for driving the alignment driving member 71 to move along the axial direction of the to-be-machined thrust wheel 4 clamped by the clamp 3 so as to enable the first cutter assembly 1 and the second cutter assembly 2 to approach the clamp 3 or to be away from the clamp 3.
Wherein, both the two alignment driving members 71 and the two horizontal driving members 72 can be air cylinders or oil cylinders. As shown in fig. 1, when both the two alignment driving members 71 and the two horizontal driving members 72 are air cylinders or oil cylinders, the alignment driving members 71 may be obliquely disposed on the frame 7. Further, the frame 7 may be provided with a table 70 inclined toward the jig 3, and the alignment drive 71 is mounted on the inclined table 70. At this time, as shown in fig. 1, the axial directions of the output shafts of the two alignment drivers 71 are perpendicular to the axial direction of the to-be-machined thrust wheel 4 held in the jig 3, and the axial directions of the output shafts of the two horizontal drivers 72 are parallel to the axial direction of the to-be-machined thrust wheel 4 held in the jig 3.
One of the alignment drives 71 can change the height of the first tool assembly 1 and can change the spacing between the first tool assembly 1 and the gripper 3 in the horizontal plane in the radial direction of the bogie wheel 4 to be machined in the gripper 3. The further alignment drive 71 can change the height of the second tool assembly 2 and can change the spacing between the second tool assembly 2 and the holder 3 in the horizontal plane in the radial direction of the track wheel 4 to be machined in the holder 3.
It can be seen that one of the alignment drives 71 can enable one end of the to-be-machined thrust wheel 4 in the first tool assembly 1 and the clamp 3 to be opposed, and the other alignment drive 71 enables the other end of the to-be-machined thrust wheel 4 in the second tool assembly 2 and the clamp 3 to be opposed. Furthermore, the two alignment drives 71 can drive the first tool assembly 1 and the second tool assembly 2 away from the clamp 3, so that the first tool assembly 1 and the second tool assembly 2 have a distance in the height direction from the clamp 3, which prevents influencing the process of feeding the thrust wheel 4 to be machined into the clamp 3 and influencing the process of removing the machined thrust wheel 4 from the clamp 3.
Wherein the two alignment drives 71 can be synchronously extended and retracted, and the height of the first tool assembly 1 and the position of the second tool assembly 2 can be synchronously changed.
In the present embodiment, one of the horizontal drives 72 can change the position of the first tool assembly 1 in the axial direction of the track wheel 4 to be machined in the jig 3, and the other horizontal drive 72 can change the position of the second tool assembly 2 in the axial direction of the track wheel 4 to be machined in the jig 3. It can be seen that the two horizontal driving members 72 can drive the first tool assembly 1 and the second tool assembly 2 to approach the fixture 3, so that the first tool assembly 1 and the second tool assembly 2 can be abutted against two ends of the supporting wheel 4 to be machined in the fixture 3, and preparation is made for machining two ends of the supporting wheel 4 to be machined. In addition, the two horizontal driving members 72 can drive the first cutter assembly 1 and the second cutter assembly 2 to be far away from the clamp 3, so that the first cutter assembly 1 and the second cutter assembly 2 can be abducted for the process of feeding the thrust wheel 4 to be machined into the clamp 3 and the process of taking the machined thrust wheel 4 out of the clamp 3.
As shown in fig. 1, the thrust roller machining apparatus provided in this embodiment further includes two sliding seats 73, a first guide rail 74 is provided on the frame 7 in a direction parallel to the axis of the thrust roller 4 to be machined clamped by the clamp 3, and two horizontal driving members 72 are mounted on the first guide rail 74. A slide carriage 73 is connected to the output shaft of each of the two horizontal driving members 72, and both slide carriages 73 are slidably connected to the first guide rail 74. A second guide rail 730 is mounted on each of the two carriages 73 in a direction perpendicular to the direction of extension of the first guide rail 74, the first cutter assembly 1 being slidably connected to one of the second guide rails 730, and the second cutter assembly 2 being slidably connected to the other second guide rail 730.
One of the alignment drivers 71 is mounted on one of the slides 73 and the output shaft of the alignment driver 71 is connected to the first cutter assembly 1. A further alignment drive 71 is mounted on a further carriage 73 and the output shaft of the alignment drive 71 is connected to the second cutter member 2.
The cooperation between the sliding base 73 and the first guide rail 74 can make the process of driving the sliding base 73 to move axially along the to-be-machined thrust wheel 4 clamped by the clamp 3 by the horizontal driving piece 72 smoother and more stable.
Wherein the axial direction of the output shaft of the alignment driver 71 is parallel to the length direction of the second guide rail 730. The cooperation between the first cutter assembly 1 and one of the second guide rails 730 can make the process of driving the first cutter assembly 1 to move by the alignment driving member 71 more smooth and stable. The cooperation between the second cutter member 2 and the other second guide rail 730 can make the process of driving the second cutter member 2 to move by the alignment driving member 71 more smoothly and stably.
As shown in fig. 1, the first tool assembly 1 includes a first tool 10, a first turret 11, and a first tool holder 12, the first turret 11 being mounted on the first tool holder 12, the first tool 10 being mounted on the first turret 11. The second tool assembly 2 comprises a second tool 20, a second turret 21 and a second tool holder 22, the second turret 21 being mounted on the second tool holder 22 and the second tool 20 being mounted on the second turret 21.
