It should be noted that, the door spindle is formed by a rotating shaft and a side plate assembled and welded on the rotating shaft, the carrier 21 is provided with a side plate 22 mounting position to be welded and a rotating shaft 23 mounting position, when the side plate 22 to be welded and the rotating shaft 23 are mounted on the corresponding mounting positions, the positioning procedure of the weldment can be completed, the corresponding mounting position of the side plate 22 to be welded is the mounting groove 213 on the first carrier 211, the corresponding mounting position of the rotating shaft 23 to be welded is the V-shaped groove 214 on the second carrier 212, and the feeding mechanism 3 is provided with the rotating shaft 23 to be welded and can feed the rotating shaft 23 to be welded one by one.
The workflow of this embodiment is as follows: when the carrier 21 loaded with the side plate 22 to be welded is conveyed below the feeding mechanism 3 by the conveying mechanism 2, the feeding mechanism 3 releases the rotating shaft 23 to be welded onto the V-shaped groove 214 of the second carrier 212, and the side plate 22 to be welded is assembled and positioned with the rotating shaft 23 to be welded through the carrier 21, so that the positioning procedure of a welding part is finished, and meanwhile, the rotating shaft 23 to be welded is difficult to move or rotate under the prevention of the anti-skid part because the V-shaped groove 214 is provided with the anti-skid part, the positioning and mounting accuracy is ensured, and the welding quality is improved; when the carrier 21 reaches the installation position of the welding mechanism 4, the welding mechanism 4 can perform assembly welding on the side plate 22 to be welded and the rotating shaft 23, so that the side plate 22 to be welded and the rotating shaft 23 are assembled and welded to form a door shaft, and after the welding process is finished, the conveying mechanism 2 sends the door shaft to the unloading station to unload or directly takes the door shaft out of the carrier 21 by the unloading mechanism. Therefore, automation of door spindle manufacturing, namely automatic feeding, positioning and automatic welding is realized, and as positioning and welding are completed by a mechanical structure, labor cost is reduced, production efficiency is improved, and product consistency is improved.
The anti-slip member disposed on the V-shaped groove 214 may be an anti-slip pad 215 or a first serration 216, and the anti-slip member disposed on the V-shaped groove 214 of the present embodiment includes both the anti-slip pad 215 and the first serration 216.
Specifically, as shown in fig. 3, in this embodiment, the bottom of the V-shaped groove 214 is in a circular arc shape, and the anti-slip member is an anti-slip pad 215 that is tightly attached to the bottom of the V-shaped groove 214. Because the anti-slip pad 215 is clung to the bottom of the V-shaped groove 214, the bottom of the anti-slip pad 215 and the bottom of the V-shaped groove 214 are arc-shaped, the rotating shaft 23 can be partially coated by the shape, the contact surface is large, the friction force is increased, the anti-slip pad 215 is made of flexible nonmetallic materials such as rubber or silica gel, and the friction force between the anti-slip pad 215 and the rotating shaft 23 can be further increased, so that the rotating shaft 23 is prevented from moving or rotating, the positioning and mounting accuracy of the rotating shaft 23 is ensured, and the welding quality is improved.
As further shown in fig. 3, in this embodiment, the anti-slip member is a first serration 216 disposed on the beveled edge of the V-shaped groove 214. The first saw teeth 216 are formed by a plurality of protrusions, and friction force between the first saw teeth 216 and the rotating shaft 23 can be increased by the protrusions, so that the rotating shaft 23 is prevented from moving or rotating, positioning and mounting accuracy of the rotating shaft 23 is ensured, and welding quality is improved.
In the present embodiment, the operation of the transfer mechanism 2, the feeding of the feeding mechanism 3, and the welding of the welding mechanism 4 are controlled by a controller. The frame 1 is provided with a reference position, the time from the reference position to the feeding mechanism 3 of the carrier 21 is set to be T1, and the time from the reference position to the welding mechanism 4 of the carrier 21 is set to be T2. When the device starts to operate, the carrier 21 starts to move from the reference position, the controller starts to count time, after the time T1, the carrier 21 moves to the position below the release opening of the feeding mechanism 3, and at the moment, the feeding mechanism 3 acts to release the rotating shaft 23 to be welded to the carrier 21; after the time T2 has elapsed, the carrier 21 is moved to the mounting position of the welding mechanism 4, and at this time, the welding mechanism 4 is operated to weld the side plate 22 to be welded on the carrier 21 and the rotating shaft 23 into one body. Further, the conveying mechanism 2 is provided with a plurality of carriers 21 which are uniformly arranged, when the nth carrier 21 reaches the installation position of the welding mechanism 4 in the running process of the device, the nth carrier 21 reaches the lower part of the feeding mechanism 3, at this time, t1=t2, that is, when the side plate 22 to be welded on the nth carrier 21 is assembled and welded with the rotating shaft 23, the nth carrier 21 is provided with the rotating shaft 23 to be welded, so that the positioning of the door shaft and the welding manufacturing process can be continuously carried out, and the production efficiency is further improved.
As shown in fig. 4, in order to facilitate the release of the materials, in this embodiment, the feeding mechanism 3 includes a hopper 31, the hopper 31 is mounted on the frame 1, the hopper 31 is provided with a discharge channel 33 and at least one inclined plane 35, the inclined plane 35 is connected with the discharge channel 33, and a discharge port 34 is provided at the end of the discharge channel 33. The inclined plane 35 can enable the materials to move downwards under the action of gravity, so that the materials can be discharged out of the hopper 31, and the discharging channel 33 can guide the materials moving downwards to a position needing to be released.
As further shown in fig. 4, when there is a lot of material in the hopper 31, the friction force between the materials will hinder the movement of the materials, so that in order to make the materials move down well, in this embodiment, the inclined surface 35 is provided with a spindle driving mechanism 36, and the spindle driving mechanism 36 drives the spindle 23 to be welded to move toward the discharge hole 34. The spindle drive 36 is a positive drive that applies a force to the material that is greater than the friction between the materials, thereby providing good movement of the material toward the discharge port 34.
As shown in fig. 5, since there is only one carrier 21 passing under the feeding mechanism 3, only one rotating shaft is required for each release of the feeding mechanism 3, in order to release the rotating shafts piece by piece, in this embodiment, the inner wall of the discharging channel 33 is sequentially provided with a first clamping block 37 and a second clamping block 38, when the carrier 21 moves out under the discharging channel 33, the first clamping block 37 is contracted, the second clamping block 38 is protruded, so that the rotating shaft 23 to be welded is installed in the area between the first clamping block 37 and the second clamping block 38, and when the carrier 21 is positioned under the discharging channel 33, the first clamping block 37 is protruded, and the second clamping block 38 is contracted, so that the rotating shaft 23 to be welded is released onto the carrier 21. It should be noted that, the protrusions of the first clamping block 37 and the second clamping block 38 can clamp the rotating shaft 23 to be welded in the discharging channel 33, and the shrinkage of the first clamping block 37 and the second clamping block 38 can enable the rotating shaft 23 to be welded to move down in the discharging channel 33. When the front rotating shaft is released to the carrier 21, the rear rotating shaft can be clamped in the discharging channel 33 due to the fact that the first clamping block 37 is protruded at the moment, so that the gradual release of the rotating shaft is realized, and the device is simple in structure and convenient to control.
As shown in fig. 6, in order to adjust the positional relationship between the welding mechanism and the carrier and facilitate welding, in this embodiment, the welding mechanism 4 includes a four-axis numerical control system 41 and a welding gun 42, the welding gun 42 is mounted on the four-axis numerical control system 41, and when the carrier 21 is conveyed to the mounting position of the welding gun 42 by the conveying mechanism 2, the welding gun 42 moves and rotates relative to the frame 1 under the action of the four-axis numerical control system 41, so that the joint between the side plate 22 to be welded and the rotating shaft 23 to be welded is welded. The four-axis numerical control system 41 can enable the welding gun 42 to move and rotate in six directions, such as front, back, left, right, up, down and the like, relative to the frame 1, so that when the carrier 21 reaches the installation position of the welding mechanism 4, the welding gun 42 can perform assembly welding on the side plate 22 to be welded on the carrier 21 and the rotating shaft 23 in a lifting, descending, rotating and other modes. Because the welding mechanism 4 is used to realize the assembly welding of the side plate 22 to be welded and the rotating shaft 23 in the present invention, all the welding mechanisms capable of realizing the assembly welding of the side plate 22 and the rotating shaft 23 in the prior art can replace the welding mechanism 4 in the embodiment of the present invention.
As further shown in fig. 6, the four-axis numerical control system 41 includes an X-axis linear driving mechanism 43, a Y-axis linear driving mechanism 44, a Z-axis linear driving mechanism 45, and a rotating mechanism 46, the X-axis linear driving mechanism 43 is mounted on the frame 1, the Y-axis linear driving mechanism 44 is mounted on the X-axis linear driving mechanism 43, the Z-axis linear driving mechanism 45 is mounted on the Y-axis linear driving mechanism 44, the rotating mechanism 46 is mounted on the Z-axis linear driving mechanism 45, and the welding gun 42 is mounted on the rotating mechanism 46. The X-axis linear driving mechanism 43, the Y-axis linear driving mechanism 44, and the Z-axis linear driving mechanism 45 can move the welding gun 42 back and forth, left and right, and up and down, respectively, with respect to the frame 1, and the rotation mechanism 46 can rotate the welding gun 42. When the carrier 21 reaches the installation position of the welding mechanism 4, the Y-axis linear driving mechanism 44 drives the welding gun 42 to move along with the carrier 21, so that the welding gun 42 and the carrier 21 keep a relatively static state, and simultaneously, under the action of the Z-axis linear driving mechanism 45 and the rotating mechanism 46, the welding gun 42 is adjusted to an optimal welding position and the assembly welding of the side plate 22 to be welded and the rotating shaft 23 is performed. After the welding operation is completed, the welding gun 42 is reset under the driving of the Y-axis linear driving mechanism 44. Whether the welding operation is completed or not can be judged by presetting the welding time, namely, setting the welding time to be T3, when the welding gun 42 starts to weld, the controller starts to time, and after the T3 time passes, the controller can judge that the welding operation is completed.
Referring further to fig. 1, in order to prevent the rotation shaft 23 to be welded from moving before or during assembly welding, which results in inaccurate positioning during assembly welding, a pressing mechanism 7 is further provided in this embodiment, the pressing mechanism 7 is mounted on the frame 1, and the pressing mechanism 7 is used for pressing the rotation shaft 23 to be welded on the carrier 21 during assembly welding of the side plate 22 to be welded and the rotation shaft 23.

The actuation of the pressing mechanism 7 is associated with the actuation of the welding mechanism 4, i.e. when the carrier 21 reaches the installation position of the welding mechanism 4, the pressing mechanism 7 presses the rotating shaft 23 to be welded; after the welding operation is completed, the pressing mechanism 7 is disengaged from the rotating shaft 23.
With further reference to fig. 1, in this embodiment, the device further includes a gripping mechanism 5, where the gripping mechanism 5 is mounted on the frame 1, and the gripping mechanism 5 is used to move the assembled side plate 22 and the rotating shaft 23 out of the carrier 21 and send them to the rack for placement. After the door spindle welding procedure is finished, the conveying mechanism 2 conveys the door spindle to the unloading station for unloading, and in order to reduce labor cost, unloading automation is realized, and therefore, the grabbing mechanism 5 is installed at the unloading station of the frame 1.

With further reference to fig. 1, in this embodiment, a proximity switch 6 is further included, the proximity switch 6 being mounted on the frame 1, the proximity switch 6 being used to alternatively control the actuation of the transfer mechanism 2 or the welding mechanism 4. When the metal detection body is close to the induction area of the proximity switch, the proximity switch can send out an electrical instruction to accurately reflect the position and the travel of the movement mechanism, so that the proximity switch can be used for judging the position of the carrier 21, and the control method has the advantage of being accurate in control. Specifically, when the carrier 21 is alternatively conveyed to the lower side of the feeding mechanism 3 or the installation position of the welding mechanism 4 by the conveying mechanism 2, the feeding mechanism 3 releases the rotating shaft 23 to be welded to the carrier 21 or the welding mechanism 4 performs assembly welding on the side plate 22 to be welded and the rotating shaft 23.
