Description

Technical Field

[0001] This utility model belongs to the field of polishing technology, and in particular relates to a small gear appearance polishing machine. Background Technology

[0002] Gears, mechanical parts with interlocking teeth, play a crucial role in mechanical transmission and a wider range of mechanical fields due to their unique meshing characteristics. Gear surface polishing refers to grinding the outer surface of the gear to make it smooth and flat.

[0003] Existing technologies still have some problems when grinding the surface of gears: when grinding the top and bottom surfaces of gears, the clamps used to hold the gears cover part of the gear surfaces, which means that some surfaces of the gear cannot be ground during the grinding process. After the grinding equipment has finished grinding, the operator needs to manually remove the gear and then manually grind the unground areas with a handheld grinder, resulting in low efficiency in grinding the gear surface. Utility Model Content

[0004] To address the issue of incomplete grinding of gear surfaces during the polishing process, where after grinding by equipment, operators must manually remove the gear and then manually grind the unpolished areas with a handheld grinder, resulting in low grinding efficiency, this invention provides a small gear surface polishing machine. The technical solution is as follows: A small gear surface polishing machine is provided, comprising: a polishing table 1, an L-shaped frame 11, a cylinder 12, and a polishing machine 13. The L-shaped frame 11 is fixedly mounted on the upper surface of the polishing table 1, the cylinder 12 is fixedly mounted on one end of the L-shaped frame 11, and the body of the polishing machine 13 is fixed to the piston end of the cylinder 12. The upper surface of the polishing table 1 is provided with an equipment groove 14 and a workpiece groove 15, the workpiece groove 15 and the equipment groove 14 are coaxial, the equipment groove 14 and the workpiece groove 15 are provided with a positioning and clamping mechanism 2, and the equipment groove 14 is provided with a rotating mechanism 3. The positioning and clamping mechanism 2 includes several arc-shaped plates 21 and a positioning disk 25. The arc-shaped plates 21 are arranged in a ring array above the workpiece groove 15. The positioning disk 25 is rotatably positioned at the axial center of the workpiece groove 15. Several L-shaped elastic elements 27 are fixedly arranged in a ring array on the upper surface of the positioning disk 25. Several limiting rods 22 are fixedly arranged on one side of the arc-shaped plates 21. A conical seat 23 is fixedly arranged at one end of the limiting rod 22. Several electric push rods 24 are arranged in a ring array on the equipment groove 14. The piston end of the electric push rod 24 is fixedly connected to the other side of the arc-shaped plate 21.

[0005] The positioning disk 25 has a fixed rotating shaft 26 on its lower surface, which is rotatably positioned at the axis of the workpiece groove 15. When the gear workpiece 100 rotates, the gear workpiece 100 can cause the rotating shaft 26 to rotate via the positioning disk 25 and the L-shaped elastic element 27, and the positioning disk 25 and the L-shaped elastic element 27 will rotate accordingly.

[0006] The rotating mechanism 3 includes a circular guide rail 31, which is fixedly mounted on the bottom wall of the equipment slot 14. A plurality of arc-shaped sliders 32, arranged in a ring array, are slidably mounted on the circular guide rail 31. The fixed end of the electric push rod 24 is fixedly connected to the inner wall of the arc-shaped sliders 32. Driving the arc-shaped sliders 32 to slide circumferentially on the circular guide rail 31 allows the gear workpiece 100 to rotate via the electric push rod 24, the arc-shaped plate 21, the limiting rod 22, and the conical seat 23.

[0007] The equipment slot 14 contains a circular toothed ring 33. The inner wall of the circular toothed ring 33 is fixedly connected to the outer walls of several arc-shaped sliders 32. A servo motor 34 is fixedly mounted on the upper surface of the grinding table 1. A rotating rod 35 is fixedly mounted on the drive output end of the servo motor 34. A drive gear 36 is fixedly mounted on one end of the rotating rod 35. The drive gear 36 meshes with the circular toothed ring 33. When the servo motor 34 is turned on, the drive shaft of the servo motor 34 causes the rotating rod 35 to rotate, which in turn causes the drive gear 36 to rotate, and the drive gear 36 drives the circular toothed ring 33 to rotate.

[0008] The servo motor 34 is fixedly mounted with an L-shaped mounting bracket 37. One end of the L-shaped mounting bracket 37 is fixedly connected to the upper surface of the grinding table 1. The L-shaped mounting bracket 37 makes the servo motor 34 more securely mounted.

[0009] Furthermore, the equipment slot 14 and the workpiece slot 15 are provided with a plurality of evenly distributed chip removal slots 16. Waste chips generated during the grinding process can be discharged through the chip removal slots 16.

[0010] The lower surface of the polishing table 1 is fixedly provided with a support base 17. The support base 17 ensures that the polishing table 1 can always work stably.

[0011] The beneficial effects of this utility model are at least as follows: 1. Through the positioning and clamping mechanism, the limiting rod and conical seat in the positioning and clamping mechanism are inserted into the teeth of the gear workpiece to clamp the gear workpiece. At the same time, the mounting hole of the gear workpiece is fitted onto the L-shaped elastic element and the positioning plate to achieve positioning and clamping of the gear workpiece. This ensures that the entire surface of the gear workpiece is exposed to the outside after clamping, and that the entire upper surface of the gear workpiece is polished in one go, thereby improving the polishing efficiency of the gear workpiece and saving the operation time of manual polishing. 2. Through the set rotating mechanism, the circumferential sliding of the arc-shaped slider of the rotating mechanism causes the gear workpiece to rotate through the positioning and clamping mechanism, so that other positions on the upper surface of the gear workpiece are vertically aligned with the grinding wheel of the grinding machine, so that the grinding wheel of the grinding machine can perform grinding processing, thereby improving the grinding efficiency of the gear workpiece.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-5 As shown, this utility model provides a small gear surface grinding machine, including a grinding table 1, an L-shaped frame 11, a cylinder 12, and a grinding machine 13. The L-shaped frame 11 is fixedly installed on the upper surface of the grinding table 1, and the cylinder 12 is fixedly installed at one end of the L-shaped frame 11. The body of the grinding machine 13 is fixed to the piston end of the cylinder 12. During the grinding operation of the gear workpiece 100, the piston end of the cylinder 12 can push the grinding machine 13 to descend vertically. The grinding wheel of the grinding machine 13 contacts the upper surface of the gear workpiece 100 and performs grinding processing on the upper surface of the gear workpiece 100.

[0023] The upper surface of the grinding table 1 is provided with an equipment slot 14 and a workpiece slot 15. The gear workpiece 100 to be ground is placed in the workpiece slot 15 for grinding. The workpiece slot 15 is coaxial with the equipment slot 14. Several chip removal slots 16 are evenly distributed on the equipment slot 14 and the workpiece slot 15. By setting the chip removal slots 16, the waste chips generated during the grinding process can be discharged through the chip removal slots 16.

[0024] A support frame 17 is fixedly installed on the lower surface of the grinding table 1. Positioning and clamping mechanisms 2 are provided on the equipment slot 14 and workpiece slot 15. A rotating mechanism 3 is provided on the equipment slot 14. By setting up the positioning and clamping mechanism 2, the gear workpiece 100 can be positioned and clamped, fixing it at the axial position of the workpiece slot 15. Simultaneously, the upper surface of the gear workpiece 100 is completely exposed to the external environment for grinding by the grinding wheel of the grinding machine 13. By setting up the rotating mechanism 3, the clamped gear workpiece 100 can be rotated, thereby enabling comprehensive grinding of the upper surface of the gear workpiece 100.

[0025] The positioning and clamping mechanism 2 includes an arc-shaped plate 21 and a positioning disk 25. Four arc-shaped plates 21 are arranged in a ring array above the workpiece groove 15. The positioning disk 25 is rotatably positioned at the axial center of the workpiece groove 15. A plurality of L-shaped elastic elements 27 are fixedly arranged in a ring array on the upper surface of the positioning disk 25, and a rotating shaft 26 is fixedly arranged on the lower surface of the positioning disk 25, rotatably positioned at the axial center of the workpiece groove 15. By setting the positioning disk 25 and the L-shaped elastic elements 27, when the mounting hole of the gear workpiece 100 passes through the L-shaped elastic element 27, it can be fitted onto the outer wall of the positioning disk 25 and the L-shaped elastic element 27, thus ensuring that the gear workpiece 100 is always coaxial with the workpiece groove 15. By setting the rotating shaft 26, when the gear workpiece 100 rotates, the gear workpiece 100 can cause the rotating shaft 26 to rotate via the positioning disk 25 and the L-shaped elastic elements 27, and the positioning disk 25 and the L-shaped elastic elements 27 will rotate accordingly.

[0026] A number of limiting rods 22 are fixedly installed on one side of the arc-shaped plate 21, and a conical seat 23 is fixedly installed at one end of each limiting rod 22. Four electric push rods 24 are arranged in a ring array on the equipment slot 14, and the piston end of each electric push rod 24 is fixedly connected to the other side of the arc-shaped plate 21. By setting the limiting rods 22 and the conical seat 23, when the limiting rods 22 and the conical seat 23 enter between two adjacent teeth of the gear workpiece 100, the gear workpiece 100 can be clamped, thus achieving the clamping of the gear workpiece 100.

[0027] The rotating mechanism 3 includes a circular guide rail 31, which is fixedly mounted on the bottom wall of the equipment slot 14. Several arc-shaped sliders 32 arranged in a ring array are slidably mounted on the circular guide rail 31. The fixed end of the electric push rod 24 is fixedly connected to the inner side wall of the arc-shaped sliders 32. By driving the arc-shaped sliders 32 to slide circumferentially on the circular guide rail 31, the arc-shaped sliders 32 can rotate the gear workpiece 100 through the electric push rod 24, the arc plate 21, the limiting rod 22 and the conical seat 23.

[0028] A circular toothed ring 33 is provided inside the equipment slot 14. The inner wall of the circular toothed ring 33 is fixedly connected to the outer wall of several arc-shaped sliders 32. By driving the circular toothed ring 33 to rotate, the circular toothed ring 33 can make the arc-shaped sliders 32 slide circumferentially on the circular guide rail 31. A servo motor 34 is fixedly provided on the upper surface of the grinding table 1. An L-shaped mounting bracket 37 is fixedly provided on the body of the servo motor 34. One end of the L-shaped mounting bracket 37 is fixedly connected to the upper surface of the grinding table 1. A rotating rod 35 is fixedly provided at the drive output end of the servo motor 34. A drive gear 36 is fixedly provided at one end of the rotating rod 35. The drive gear 36 is meshed with the circular toothed ring 33. By turning on the servo motor 34, the drive shaft of the servo motor 34 can make the rotating rod 35 rotate. The rotating rod 35 can make the drive gear 36 rotate. The drive gear 36 can drive the circular toothed ring 33 to rotate.

[0029] The working principle of this utility model is as follows: When the gear workpiece 100 needs to be polished, the operator first places the gear workpiece 100 above the positioning plate 25, so that the mounting hole at the shaft center of the gear workpiece 100 is vertically aligned with the positioning plate 25. Then, the gear workpiece 100 is moved down, and the mounting hole passes through multiple L-shaped elastic elements 27. The multiple L-shaped elastic elements 27 deform and contract until the lower surface of the gear workpiece 100 contacts the bottom wall of the workpiece groove 15. At this time, the wall of the mounting hole of the gear workpiece 100 contacts the multiple L-shaped elastic elements 27 and the outer wall of the positioning plate 25. Subsequently, the operator activates four electric push rods 24. The piston ends of the four electric push rods 24 extend, pushing four arc-shaped plates 21 to move towards the axis of the workpiece groove 15. At this time, multiple limiting rods 22 and conical seats 23 on the four arc-shaped plates 21 enter between two adjacent teeth of the gear workpiece 100 (if the conical seat 23 abuts against the teeth of the gear workpiece 100, the gear workpiece 100 is manually rotated to make fine adjustments to ensure that the conical seat 23 can smoothly abut against the two adjacent teeth), thus securing the gear workpiece 100 and conveniently achieving the positioning and clamping of the gear workpiece 100, fixing the gear workpiece 100 at the axis of the workpiece groove 15, while simultaneously exposing the upper surface of the gear workpiece 100 completely to the external environment, ensuring that the upper surface of the gear workpiece 100 is completely polished. When the piston of cylinder 12 pushes the grinder 13 to descend vertically, the grinding roller of the grinder 13 contacts the upper surface of the gear workpiece 100. As the grinding wheel of the grinder 13 rotates at high speed, the grinding wheel of the grinder 13 grinds the contact position on the upper surface of the gear workpiece 100. After the grinding wheel finishes grinding the contact area between itself and the upper surface of the gear workpiece 100, the operator raises the grinding machine 13 using cylinder 12, causing the grinding wheel of the grinding machine 13 to disengage from the gear workpiece 100. Then, the servo motor 34 is turned on. The drive shaft of the servo motor 34 rotates the drive gear 36 via the rotating rod 35. The drive gear 36 drives the circular gear ring 33 to rotate. The circular gear ring 33 causes the four arc-shaped sliders 32 to slide circumferentially on the circular guide rail 31. The four arc-shaped sliders 32 rotate the gear workpiece 100 via the corresponding electric push rod 24, arc plate 21, limit rod 22, and conical seat 23, so that the other grinding positions of the gear workpiece 100 are vertically aligned with the grinding wheel of the grinding machine 13. Then, the grinding machine 13 is lowered using cylinder 12 to perform comprehensive grinding on the upper surface of the gear workpiece 100, thereby improving the efficiency of grinding the upper and lower surfaces of the gear workpiece 100.

[0030] The above description merely illustrates the embodiments of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Furthermore, any parts of this utility model not described in detail are conventional techniques.
