After the machined gear is clamped into the standard tooth sleeve 7, the tooth shape of the machined gear is filled into the standard tooth groove of the standard tooth sleeve 7, the standard tooth shape 8 of the standard tooth sleeve 7 is filled into the tooth groove of the machined gear, the standard tooth shape 8 and the tooth shape end face of the machined gear are tightly matched, the end face of the standard tooth shape 8 and the tooth shape end face of the machined gear form a continuous plane, when the tooth shape end face of the machined gear is turned by a turning tool, the end face of the standard tooth shape 8 is machined at the same time, the phenomenon that the turning tool frequently collides with the tooth shape due to the fact that discontinuous tooth grooves appear is avoided, the damage probability of the turning tool can be reduced, and the cost of the cutting tool is reduced.
In order to stably position a gear to be processed and ensure that the end face of the gear to be processed coincides with the end face of a standard tooth form 8, a pressing block 9 is sleeved on a positioning shaft 12 in a standard tooth sleeve 7, the pressing block 9 is in sliding fit with the positioning shaft 12, a plurality of compression screws 10 in threaded fit with a fixed ring plate 6 are arranged on the fixed ring plate 6, and the end parts of the compression screws 10 are in rotary connection with the pressing block 9. When the compression screw 10 is rotated, the pressing block 9 can be driven to axially slide along the positioning shaft 12. The outer side of the standard tooth sleeve 7 is provided with a plurality of connecting rods 11, one end of each connecting rod 11 is provided with a U-shaped positioning frame 13, the positioning frame 13 is provided with a rotatable press roller 14, and the axial direction of the press roller 14 is consistent with the radial direction of the standard tooth sleeve 7; the other end of the connecting rod 11 is provided with a tension mechanism 15, and the tension mechanism 15 is mounted on the lathe bed 1. The connecting rod 11 is parallel to the positioning shaft 12.
When the gear is positioned, the positioning shaft 12 can be detached from the hydraulic chuck 16, the gear to be machined is sleeved on the positioning shaft 12, all tooth shapes of the gear to be machined enter standard tooth grooves of the standard tooth sleeve 7, then the positioning shaft 12 is installed on the hydraulic chuck 16, the tension mechanism 15 is used for driving the connecting rod 11 and the compression roller 14 to move along the axial direction of the positioning shaft 12 until the compression roller 14 compresses the end surfaces of the standard tooth sleeve 7 and the gear to be machined, finally the compression screw 10 is rotated, the pressing block 9 is pushed by the compression screw 10 to compress the gear to be machined, at the moment, both end surfaces of the gear to be machined are compressed, the temperature can be kept, part of the compression roller 14 is in contact with the end surface of the standard tooth sleeve 7, part of the compression roller 14 is in contact with the end surface of the gear to be machined, and the end surface of the standard tooth sleeve 7 can be guaranteed to be completely overlapped with the end surface of the gear to be machined. The tension mechanism 15 may be a hydraulic cylinder.
After the gear clamping is completed, the main shaft driving mechanism 4 can be started, the main shaft driving mechanism 4 drives the main shaft 2 to rotate, the main shaft 2 drives the positioning shaft 12 to rotate through the hydraulic chuck 16, and the positioning shaft 12 drives the fixed ring plate 6, the pressing block 9, the gear to be processed, the standard tooth sleeve 7 and the like to integrally rotate. Because the compression roller 14 is rotatably arranged on the positioning frame 13, when the gear to be processed and the standard tooth sleeve 7 rotate, the compression roller 14 is driven to rotate through friction, the friction force born by the gear to be processed, the standard tooth sleeve 7 and the compression roller 14 is reduced, and the compression roller 14 can be made of the same material as the grinding head 27 and is resistant to abrasion.
The number of the press rolls 14 may be three or four, and the turning tool or grinding head 27 is located between the two press rolls 14 during turning or grinding, and the turning tool or grinding head 27 moves along the radial direction of the gear to be machined, and does not interfere with the press rolls 14.
Because the standard tooth form 8 and the standard tooth slot of the standard tooth sleeve 7 are both standard sizes and have higher dimensional accuracy, the dimensional accuracy of the tooth form of the gear to be processed can be determined by measuring the fit clearance between the tooth form of the gear to be processed and the wall of the standard tooth slot, and if the fit clearance between the tooth form of the gear to be processed and the wall of the standard tooth slot is larger or the tooth form of the gear to be processed cannot enter the standard tooth slot, the tooth form dimensional error of the gear to be processed is larger. It can be seen that the standard tooth cover 7 of the present invention also has the function of tooth form dimension detection.
In the turning and grinding process, the end face of the standard tooth sleeve 7 is machined simultaneously, so that the length of the standard tooth sleeve 7 is gradually reduced, but the consumption speed of the standard tooth sleeve 7 is low because the finishing allowance of the end face of the gear is small and generally not more than 1mm, and one standard tooth sleeve 7 can meet the machining consumption of a plurality of gears, so that the consumption cost of the standard tooth sleeve 7 is low.
The fixed ring plate 6 is detachably mounted on the positioning shaft 12 so as to be convenient for replacing a new fixed ring plate 6 and the standard tooth sleeve 7.
A first pressure sensor 22 is arranged between the tension mechanism 15 and the connecting rod 11, a grinding head 27 is connected with a mounting block 28, a second pressure sensor 29 is arranged between the grinding head 27 and the mounting block 28, the mounting block 28 is detachably connected with a main shaft of the grinding motor 26, the first pressure sensor 22 and the second pressure sensor 29 are both connected with a controller 30, and the tension mechanism 15 and the grinding motor 26 are both connected with the controller 30.
The first pressure sensor 22 can detect the tension between the tension mechanism 15 and the connecting rod 11, and transmits a detection signal to the controller 30, so that the pressure of the pressing roller 14 to the gear to be processed and the standard tooth sleeve 7 is obtained, and the controller 30 adjusts the tension of the tension mechanism 15 according to the detection result, so that the pressure of the pressing roller 14 to the gear to be processed and the standard tooth sleeve 7 is ensured to be in a set range. The second pressure sensor 29 is used to detect the pressure between the grinding head 27 and the mounting block 28, and transmit a pressure signal to the controller 30, which can act as the pressure between the grinding head 27 and the gear end face, and the controller 30 adjusts the rotational speeds of the grinding motor 26 and the grinding head 27 according to the detection result, specifically, when the pressure is large, appropriately decreases the rotational speed of the grinding head 27, and when the pressure is small, appropriately increases the rotational speed of the grinding head 27, thereby flexibly adjusting the grinding speed.
