Description

Technical Field

[0001] This utility model belongs to the technical field of chamfering equipment, specifically relating to an improved chamfering device for the outer ring of bearing races. Background Technology

[0002] Chamfering refers to the machining process of cutting the edges of a workpiece into a certain bevel. Chamfering is used to remove burrs generated during machining and to facilitate assembly; it is generally done at the ends of parts. The outer ring of a bearing is a crucial annular component. Before heat treatment, the outer ring must be chamfered during rough machining. This plays a vital role in stress release, redistribution of the internal structure, reducing the likelihood of cracks and deformation during heat treatment, and also addresses stress concentration issues. Most existing chamfering equipment for outer rings uses a three-jaw chuck for fixing and a push-out mechanism, requiring manual replacement of the chuck for the next workpiece, making it unsuitable for mass production. Furthermore, if the height of the outer ring changes, the chuck jaws must be adjusted accordingly, which is cumbersome. Also, because it is a vertical chamfering process, the generated chips are difficult to clean promptly, leaving chips on the chuck. Utility Model Content

Detailed Implementation

[0017] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.

[0018] Combined with appendix Figure 1-5 As shown, an improved chamfering device for bearing outer rings includes a work frame 1, a worktable 14 inclinedly installed on one side of the work frame 1, and a material receiving frame 2 disposed within the work frame 1. Support frames 18 are symmetrically installed on one side of the worktable 14, and electric slide rails 15 are symmetrically arranged on one side of the support frames 18. A material-stopping mechanism 16 is disposed on the electric slide rails 15. A gear and rack transmission mechanism 5 is disposed between the support frames 18. A drive motor 4 is mounted on the top of the gear and rack transmission mechanism 5, and a chamfering spindle 6 is connected to the bottom of the gear and rack transmission mechanism 5. A chamfering cutter head 20 is disposed at the lower end of the chamfering spindle 6. The feed trough seat 7 is provided, which includes a first side seat 25, a second side seat 24 and a feed trough 23. Both the first side seat 25 and the second side seat 24 are provided with long grooves 22. One end of the first side seat 25 is provided with a first through groove 26 and one end of the second side seat 24 is provided with a second through groove 28. A limit plate 8 is installed on the top of the second side seat 24. The bottom depth of the first through groove 26 is less than the bottom depth of the second through groove 28. Both the first through groove 26 and the second through groove 28 are provided with clamping mechanisms on one side. The feed trough seat 7 is symmetrically provided with baffle strips 13 on one side to ensure that the outer ring 9 of the bearing ring can fall smoothly into the receiving frame 2.

[0019] The gear and rack transmission mechanism 5 includes a driving gear, a rack, and a driven gear. The driving gear is connected to the output shaft of the drive motor 4. The rack is meshed with the driving gear and the driven gear. Through the transmission of the driving gear, the rack, and the driven gear, the chamfered main shaft 6, which is connected to the driven gear, rotates.

[0020] In addition, the tilt angle of the worktable 14 is set according to the bearing ring outer ring 9 being able to automatically feed downward along the feed groove 23. The width of the first side seat 25 and the second side seat 24 perpendicular to the feed direction is the same. The chamfering spindle 6 is internally integrated with a hydraulic or pneumatic system to realize the extension and retraction of the chamfering cutter head 20. The material receiving frame 2 is provided with a front frame and a rear frame. Multiple screen holes are evenly distributed inside the front frame and the rear frame. The front frame is used to place the bearing ring outer ring 9, and the rear frame is used for some chips to pass through. The bottom of the material receiving frame is also provided with a pull-out waste collection box for collecting chip waste.

[0021] Specifically, the material blocking mechanism 16 includes a sliding seat plate 30, a connecting rod assembly 17, a rotating base 21, and a material blocking post 19. The top of the connecting rod assembly 17 is fixedly installed on the sliding seat plate 30. The rotating base 21 includes a fixed seat set on the worktable 14 and a pin mounted on the fixed seat. The connecting rod assembly 17 includes a fixed rod, an intermediate rod, and a swing rod. The top of the fixed rod is installed on the sliding seat plate 30. The fixed rod and the swing rod are connected by the intermediate rod. The pin passes through the swing rod, allowing the swing rod to rotate around the pin. The material blocking post 19 is installed at one end of the swing rod. One side of the material blocking post 19 abuts against the outer ring 9 of the bearing sleeve. When the sliding seat plate 30 moves up or down, the material blocking post 19 at one end of the swing rod can move down or up. In addition, the distance between the end face of the material blocking post 19 near the feed groove 23 and the nearest sidewall of the first through groove 26 and the second through groove 28 is greater than the outer diameter of the outer ring 9 of the bearing sleeve.

[0022] Specifically, the bottom of the limiting plate 8 is provided with a protrusion, which engages with the long groove 22, so that the limiting plate 8 can be engaged and installed on the second side seat 24, which is convenient for subsequent disassembly and assembly. In addition, there is a gap between the bottom surface of the limiting plate 8 and the top end face of the bearing ring outer ring 9 to avoid affecting the downward feeding of the bearing ring outer ring 9.

[0023] Specifically, a pad 29 is provided between the elongated groove 22 and the limiting plate 8. The top of the pad 29 is provided with the elongated groove 22, and the bottom of the pad 29 is provided with a protrusion. That is, the pad 29 can be engaged in the elongated groove 22 of the first side seat 25 and the second side seat 24, so that the height of the first side seat 25 and the second side seat 24 is increased accordingly. The pad 29 can be added according to actual needs.

[0024] Specifically, a sinking groove 27 is provided at the bottom of one end of the feed trough 23. A gap is left between the top of the sinking groove 27 and the side wall of the feed trough 23. The gap distance is greater than the thickness of the outer ring 9 of the bearing sleeve, so that some chips can fall into the sinking groove 27 when chamfering.

[0025] Specifically, the clamping mechanism includes a push cylinder 10, a clamping seat 11, a guide rail, and a clamping block 12. The piston rod of the push cylinder 10 is connected to the clamping seat 11. The guide rail is located at the bottom of the clamping seat 11, that is, the clamping seat 11 is slidably mounted on the guide rail. The clamping block 12 is mounted on one side of the clamping seat 11 and clamps the outer ring 9 of the bearing race through the clamping block 12.

[0026] Specifically, the clamping block 12 includes a first clamping block and a second clamping block. The bottom surface of the first clamping block contacts the bottom of the first through groove 26, and the bottom surface of the second clamping block contacts the bottom of the second through groove 28. That is, the height of the first clamping block is higher than the height of the second clamping block, so that more bearing ring outer rings 9 with the same diameter but different heights can be clamped in the future.

[0027] Specifically, one end of both the first clamping block and the second clamping block is arc-shaped, which is beneficial for better clamping the outer ring 9 of the bearing sleeve.

[0028] Specifically, the feed trough 23 is provided with multiple bearing outer rings 9.

[0029] Specifically, a feed plate 3 is provided below the baffle strip 13. The lower end of the feed plate 3 is placed inside the front frame. The feed plate 3 is provided with multiple strip-shaped holes. The tilt angle of the feed plate 3 is consistent with the tilt angle of the worktable 14 so that the outer ring 9 of the bearing ring can be fed. The strip-shaped holes facilitate some of the chips to fall into the rear frame.

[0030] In addition, the entire chamfering equipment is electrically connected to an external industrial control computer, that is, the drive motor 4, chamfering spindle 6, push cylinder 10, electric slide rail 15 and sliding seat plate 30 are all controlled by an external industrial control computer.

[0031] The specific working principle of this utility model is as follows: Based on the height of the outer ring 9 of the same specification bearing race in this batch, it is determined whether to install a pad 29 on the first side seat 25 and the second side seat 24. If the pad 29 is not required, the limiting plate 8 is directly installed on the second side seat 24. The limiting plate 8 can ensure that the outer ring 9 of the bearing race is within the feed groove 23. Then, multiple outer rings 9 of the bearing race are placed into the feed groove 23. Due to the inclined worktable 14, the outer rings 9 of the bearing race can be automatically fed towards the chamfering head 20. When the outer ring 9 of the bearing race moves directly below the chamfering head 20, the external industrial control computer controls the push cylinder 10 to push the clamping seat 11 to slide on the guide rail towards the chamfering head 20, so that the first clamping block and the second clamping block can clamp and fix the outer ring 9 of the bearing race. Then, the drive motor 4 drives the gear and rack transmission mechanism 5, which rotates the chamfering spindle 6. At this time, the external industrial control computer controls the chamfering cutter head 20 of the chamfering spindle 6 to feed towards the outer ring 9 of the bearing ring, realizing the chamfering process. Some of the chips fall into the sinker 27.

[0032] After chamfering is completed, the chamfering cutter head 20 is raised, the first and second clamping blocks retract, and the first machined bearing ring outer ring 9 moves towards the stop post 19. Simultaneously, the second bearing ring outer ring 9 to be machined moves to below the chamfering cutter head 20, and the first and second clamping blocks clamp and fix the bearing ring outer ring 9. The chamfering cutter head 20 moves downward to perform chamfering. At this time, the sliding seat plate 30 moves upward on the electric slide rail 15, causing the stop post 19 at one end of the swing rod to move downward, allowing the first machined bearing ring outer ring 9 to fall and enter the front frame of the receiving frame 2 via the feed plate 3. Some chips fall into the rear frame of the receiving frame 2 or follow the bearing ring outer ring 9 into the front frame. Finally, the chips fall through the sieve holes into the waste collection box. Then, the sliding seat plate 30 moves downward on the electric slide rail 15, causing the stop post 19 at one end of the swing rod to move upward and return to its original position.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and substitutions based on the technical solutions and inventive concepts provided by the present utility model should be covered within the protection scope of the present utility model.
