[0002] With the improvement of industrial automation, various precision gears are more and more widely used in mechanical transmission systems. The processing accuracy of gears directly affects the performance and service life of the entire transmission system. In the process of gear processing, the grinding of the gear end face is an important link. By grinding the burrs on the gear end face, it is possible to avoid damage to personnel caused by the burrs on the gear end face and effectively improve the quality of the gears.

[0003] However, usually during the process of grinding the gear end face, it is necessary to clamp the gear. The traditional method of driving the clamping block to move by screws is relatively cumbersome, and the contact area between the general clamping piece and the gear is small, which may cause the gear to shift during the grinding process, thus affecting the grinding effect. Generally, after grinding is completed, it usually requires workers to replace it, which is not conducive to continuous grinding, and most of them grind the gear end face alternately on one side, with low efficiency. Therefore, a gear end face grinding device for gear processing is needed to solve the existing deficiencies. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figures 1-5 shown, the present utility model provides a technical solution: a gear end face grinding device for gear processing, including a workbench 1. A receiving groove 2 is opened at the center of the workbench 1. A lifting mechanism 3 is arranged inside the receiving groove 2, and several workpieces 4 are movably connected to the outside of the lifting mechanism 3. A clamping and rotating mechanism 5 is arranged at the top of the workbench 1, and the clamping and rotating mechanism 5 is movably connected to the outside of the workpiece 4. A set of symmetric grinding machines 6 are movably connected to the top of the workbench 1, and the workpiece 4 is located on the opposite side of the grinding machines 6.

[0026] The grinding machine 6 includes a grinding disc, a rotating column, a support frame, a servo motor three and a hydraulic cylinder. One end of the rotating column is fixedly connected to the rear end of the grinding disc, and the other end of the rotating column is movably connected to the support frame. The bottom end of the support frame is movably connected to the top of the workbench 1. The hydraulic cylinder is fixed to the top of the workbench 1, and the telescopic end of the hydraulic cylinder is fixedly connected to one side of the support frame. The servo motor three is fixed to the top of the support frame, and the output end of the servo motor three is fixedly connected to the rotating column. The front side of the grinding disc is in contact with the end face of the workpiece 4. In addition, the tooth block 504 is arc-shaped, and the front side of the tooth block 504 meshes with the outside of the workpiece 4, so as to clamp the workpiece 4 by using the tooth block 504.

[0027] As Figure 1 、 Figure 3 and Figure 5 shown, the lifting mechanism 3 includes a support column 301, a moving ring 302, a driving rod 303 and a supporting ring 304. The driving rod 303 is movably connected to the inside of the support column 301 through a rotating shaft. The support column 301 penetrates the moving ring 302, and the support column 301 is movably connected to the moving ring 302. The support column 301 penetrates the supporting ring 304, and the support column 301 is movably connected to the supporting ring 304. The outer diameter of the supporting ring 304 is larger than the outer diameter of the moving ring 302, and the bottom end of the supporting ring 304 is fixedly connected to the top end of the moving ring 302. Threads are provided on the outside of the driving rod 303. The driving rod 303 penetrates the moving ring 302, and the driving rod 303 is threadedly connected to the moving ring 302. The support column 301 is fixedly connected to the inside of the receiving groove 2, and the workpieces 4 are all sleeved on the outside of the workpiece 4. The workpieces 4 are longitudinally linearly arranged in an array. The lifting mechanism 3 further includes a servo motor one 305. The servo motor one 305 is fixedly connected to the inside of the workbench 1, and the output end of the servo motor one 305 is fixedly connected to the bottom end of the driving rod 303.

[0028] Start the first servo motor 305 to drive the drive rod 303 to rotate inside the support column 301. Since the support column 301 longitudinally limits the moving ring 302 and the drive rod 303 is threadedly connected to the moving ring 302, the drive rod 303 drives the moving ring 302 to move upward along the support column 301, thereby pushing the supporting ring 304 to move upward along the support column 301, jacking up several workpieces 4 along the support column 301 until the top workpiece 4 moves to the opposite side of the clamping block, facilitating the movement of the top workpiece 4 to the clamping position. And when the workpiece 4 is clamped, the remaining workpieces 4 are stored, which is beneficial for the clamped workpiece 4 to have space for position adjustment.

[0029] As Figure 1 、 Figure 2 and Figure 4 shown, the clamping and rotating mechanism 5 includes a first moving frame 501, a second moving frame 502, a connecting rod 503 and a toothed block 504. The first moving frame 501 and the second moving frame 502 are symmetrically arranged, and both the first moving frame 501 and the second moving frame 502 are movably connected to the top of the workbench 1. The connecting rod 503 and the toothed block 504 are symmetrically arranged. The connecting rod 503 penetrates through the top of the first moving frame 501 and the top of the second moving frame 502 respectively, and the connecting rod 503 is movably connected to the first moving frame 501 and the second moving frame 502 through bearings respectively. The toothed blocks 504 are fixedly connected to the other ends of the connecting rod 503 respectively. The workpiece 4 is located on the opposite side of the clamping block. The clamping and rotating mechanism 5 further includes racks 505 and driving wheels 506. There are two groups of racks 505 and driving wheels 506 in total, and each group of racks 505 is symmetrically arranged with the axis of the driving wheel 506 as the origin. The driving wheel 506 is located on the opposite side of the rack 505 and meshes with the rack 505. The rack 505 is movably connected to the inside of the workbench 1, and one end of the rack 505 is fixedly connected to the bottom ends of the first moving frame 501 and the second moving frame 502 respectively. The driving wheel 506 is movably connected to the inside of the workbench 1 through a rotating shaft. A second servo motor 7 is fixedly connected to the top of the first moving frame 501, and the output end of the second servo motor 7 is fixedly connected to one end of the connecting rod 503. A hydraulic rod 8 is fixedly connected to the top of the workbench 1, and the telescopic end of the hydraulic rod 8 is fixedly connected to one side of the second moving frame 502.

[0030] Use the hydraulic rod 8 to push the second moving frame 502, causing the second moving frame 502 to move towards the workpiece 4. Under the action of the connecting rod 503, the tooth block 504 moves towards the workpiece 4, and the rack 505 at the bottom of the second moving frame 502 moves synchronously, driving the driving wheel 506 to rotate, so that the rack 505 at the bottom of the first moving frame 501 moves relatively, thereby driving the first moving frame 501 to move closer to the workpiece 4 until the teeth on the front side of the tooth block 504 mesh with the teeth on the outer side of the workpiece 4. Thus, the two tooth blocks 504 clamp the workpiece 4. By the way of tooth meshing, the clamping force of the workpiece 4 is effectively improved, making the workpiece 4 more stable when being polished, and facilitating the quick adjustment of the position of the workpiece 4, so that the end face of the workpiece 4 faces the front end of the grinding disc.

[0031] Working principle: When in use, first, sleeved several workpieces 4 on the outside of the support column 301 inside the receiving groove 2, and the supporting ring 304 supports the workpiece 4. Subsequently, start the first servo motor 305 to drive the driving rod 303 to rotate inside the support column 301. Since the support column 301 longitudinally limits the moving ring 302 and the driving rod 303 is threadedly connected to the moving ring 302, the driving rod 303 drives the moving ring 302 to move upward along the support column 301, thereby pushing the supporting ring 304 to move upward along the support column 301, jacking up several workpieces 4 along the support column 301 until the top workpiece 4 moves to the opposite side of the clamping block; Then, use the hydraulic rod 8 to push the second moving frame 502, causing the second moving frame 502 to move towards the workpiece 4. Under the action of the connecting rod 503, the tooth block 504 moves towards the workpiece 4, and the rack 505 at the bottom of the second moving frame 502 moves synchronously, driving the driving wheel 506 to rotate, so that the rack 505 at the bottom of the first moving frame 501 moves relatively, thereby driving the first moving frame 501 to move closer to the workpiece 4 until the teeth on the front side of the tooth block 504 mesh with the teeth on the outer side of the workpiece 4. Thus, the two tooth blocks 504 clamp the workpiece 4. Then, move the remaining workpieces 4 back into the receiving groove 2, and then start the second servo motor 7 to drive the connecting rod 503 to rotate. Since the clamping block tightly clamps the workpiece 4, the workpiece 4 is driven to rotate by ninety degrees. Subsequently, use the hydraulic cylinder to push the support frame to move closer to the workpiece 4 until the front side of the grinding disc fits against the end face of the workpiece 4. Use the third servo motor to control the rotation of the rotating column, thereby driving the grinding disc to rotate. Use two grinding discs to polish the two end faces of the workpiece 4 at the same time. After the polishing is completed, the polished workpiece 4 can be taken out.
