Description

Technical Field

[0001] This utility model relates to the field of grinding equipment, specifically a deburring device for the production of thrust plates. Background Technology

[0002] As a type of sliding bearing in engines, thrust washers primarily function as axial supports for the crankshaft, ensuring its circumferential rotation while preventing axial movement. After machining, the thrust washers require a grinding mechanism to remove burrs from their end faces. Existing technologies, such as the utility model patent with application number 2020218421504, disclose an automatic polishing device for thrust washers. This device uses fixed and movable clamps on a worktable to limit and fix the thrust washers. However, because thrust washers are often arc-shaped and relatively thin, this device's fixing effect is poor. During grinding, the thrust washers easily move, resulting in uneven surfaces and reduced grinding quality. Furthermore, the thrust washers are placed close to the worktable surface, making it difficult to quickly remove and replace them. Improvements are needed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a deburring device for the production of thrust plates.

[0004] To solve the above problems, the technical solution of this utility model is: a deburring device for the production of thrust plates, including an operating table, a grinding component above the operating table, and a positioning component for fixing the thrust plates below the grinding component.

[0005] The positioning assembly includes a circular plate rotatably mounted on the operating table. A positioning seat is fixed to the top of the circular plate. The positioning seat has symmetrically opened positioning grooves at both ends that are adapted to the thrust plate. An electric push rod is installed inside the positioning groove. A support plate is installed at the output end of the electric push rod. Multiple vacuum suction cups are installed through the support plate.

[0006] Furthermore, the grinding assembly includes a fixed frame mounted on the operating table. A slide rail is installed at the top of the fixed frame, and a movable plate is provided below the slide rail. A slide block that is slidably connected to the slide rail is fixed to the top of the movable plate, and a linear motor is installed at the bottom. An electric actuator is installed at the output end of the linear motor, and an equipment box is installed at the output end of the electric actuator. A servo motor is installed inside the equipment box, and a rotating shaft is installed through and rotatably on the side. The output shaft of the servo motor is connected to the rotating shaft, and a grinding wheel is installed on the rotating shaft.

[0007] Furthermore, an ear plate is fixedly connected to one side of the movable plate, and an electric actuator three is installed inside the fixed frame, with the output end of the electric actuator three connected to the ear plate.

[0008] Furthermore, an inner ring is fixed to the bottom of the circular plate, and an outer ring is fixed to the bottom surface of the operating table outside the inner ring. An annular rail is fixed inside the outer ring, and multiple sliders that are slidably connected to the annular rail are fixed to the outside of the inner ring.

[0009] Furthermore, a positioning frame is fixed to the outer side of the outer ring on the bottom surface of the operating table, and a rotary cylinder is installed on the positioning frame. The output end of the rotary cylinder is connected to the positioning seat through a connecting column.

[0010] Furthermore, a limiting ring for limiting the position of the pallet is fixed to the inner wall of the positioning groove. When the bottom surface of the pallet is in contact with the limiting ring, the distance between the top surface and the top surface of the positioning seat is less than the thickness of the thrust plate.

[0011] The advantages of this invention compared to existing technologies are as follows: This invention uses a positioning groove to position the thrust plate and uses a vacuum suction cup to fix it, thereby improving the stability of the thrust plate during grinding and improving the grinding quality; the extension of the electric push rod causes the support plate to push the thrust plate to the outside of the positioning groove, making it easy to remove and improving the practicality of the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 5 As shown, a deburring device for producing thrust plates includes an operating table 1. A grinding assembly is provided above the operating table 1. The grinding assembly includes a fixed frame 7 installed on the operating table 1. A slide rail 8 is installed at the top of the fixed frame 7. A movable plate 9 is provided below the slide rail 8. A slide seat 10 that is slidably connected to the slide rail 8 is fixed to the top of the movable plate 9. A linear motor 11 is installed at the bottom. An electric push rod 12 is installed at the output end of the linear motor 11. An equipment box 13 is installed at the output end of the electric push rod 12. A servo motor 14 is installed inside the equipment box 13. A rotating shaft 15 is installed through and rotatably on the side. The output shaft of the servo motor 14 is connected to the rotating shaft 15, and a grinding wheel 16 is installed on the rotating shaft 15. An ear plate 17 is fixed to one side of the movable plate 9. An electric push rod 18 is installed inside the fixed frame 7. The output end of the electric push rod 18 is connected to the ear plate 17.

[0020] The extension and retraction of electric push rod 18 causes ear plate 17 to drive movable plate 9 to slide along slide rail 8. Linear motor 11 drives equipment box 13 to move along the length of movable plate 9 through electric push rod 12. The height of equipment box 13 can be adjusted by the extension and retraction of electric push rod 12. Servo motor 14 drives grinding wheel 16 to rotate, which can realize all-round grinding of thrust plate.

[0021] Below the grinding assembly is a positioning assembly for fixing the thrust plate. The positioning assembly includes a circular plate 2 rotatably mounted on the operating table 1. A positioning seat 3 is fixedly connected to the top of the circular plate 2. The positioning seat 3 has symmetrically arranged positioning grooves at both ends that fit the thrust plate, and an electric actuator 4 is installed inside the positioning groove. A support plate 5 is installed at the output end of the electric actuator 4, and multiple vacuum suction cups 6 are installed through the support plate 5. An inner ring 19 is fixedly connected to the bottom of the circular plate 2, and an outer ring 20 is fixedly connected to the bottom surface of the operating table 1 outside the inner ring 19. An annular rail 21 is fixedly connected inside the outer ring 20, and multiple sliders 22 that are slidably connected to the annular rail 21 are fixedly connected to the outer side of the inner ring 19. A positioning frame 23 is fixedly connected to the bottom surface of the operating table 1 on the outer side of the outer ring 20. A rotary cylinder 24 is installed on the positioning frame 23. The output end of the rotary cylinder 24 is connected to the positioning seat 3 through a connecting column 25. A limiting ring 26 for limiting the position of the pallet 5 is fixedly connected to the inner wall of the positioning groove. When the bottom surface of the pallet 5 is in contact with the limiting ring 26, the distance between the top surface and the top surface of the positioning seat 3 is less than the thickness of the thrust plate.

[0022] A wiring groove is opened at the bottom of the positioning groove to connect the vacuum suction cup 6 to an external vacuuming device such as a vacuum pump. A two-position five-way solenoid valve (such as Delixi 4V210-08) is installed on the pipe of the vacuum suction cup 6 to control the vacuum supply and destruction. The thrust plate is placed in the positioning groove and fixed by the positioning groove and the vacuum suction cup 6, which can achieve stable fixation of the thrust plate and improve the stability of the thrust plate during grinding. After grinding is completed, the vacuum suction cup 6 stops working, and the electric push rod 4 extends to push the support plate 5 to the outside of the positioning groove, making it easy to remove the thrust plate.

[0023] The rotary cylinder 24 drives the positioning seat 3 to rotate via the connecting column 25, which can rotate the two positioning slots to the bottom of the grinding component for grinding. To prevent the wire from getting tangled, the rotary cylinder 24 rotates 180° in the forward direction and then 180° in the reverse direction, and repeats this rotation.

[0024] In practical use, this device is controlled by an external PLC controller. The thrust plate is placed in the positioning groove and fixed by the vacuum suction cup 6. The rotary cylinder 24 rotates 180° forward to drive the thrust plate to rotate under the grinding component for grinding. At this time, a new thrust plate to be ground can be placed in another positioning groove. After grinding is completed, the rotary cylinder 24 rotates 180° in the reverse direction, the vacuum suction cup 6 stops working, and at the same time the electric push rod 4 extends, and the support plate 5 pushes the thrust plate to the outside of the positioning groove for easy removal of the thrust plate.
