Description

Technical Field

[0001] This utility model relates to the field of flange fork processing technology, specifically to a tooling for deburring and grinding the surface of a flange fork. Background Technology

[0002] The flange fork is a part on the drive shaft of an automobile. Its function is to connect the drive shaft and the gearbox and transmit torque. The flange fork blank in the current technology is usually a forging. The flange fork blank is then machined to finally form the shape. Usually, the surface of the forged flange fork has burrs, which need to be removed.

[0003] Among them, announcement number CN117885026U discloses a tooling for deburring and grinding the surface of a flange fork, which includes a basic frame, a control component, a holding component, a grinding material bin, an inner bottom plate, and a filter bin. The holding component is located on both sides of the grinding material bin. The control component includes a hydraulic cylinder and a sealing cover. The sealing cover is installed at the bottom end of the hydraulic cylinder. A workpiece cavity is provided inside the grinding material bin. A pressurization port and a Smanker abrasive flow injection port are provided on the grinding material bin. A mating seat for supporting the grinding material bin is provided on the inner bottom plate, and the mating seat is adapted to the structure of the grinding material bin. A filter bin is installed on the bottom side of the inner bottom plate through a bracket. Several first injection ports are provided on the inner side wall of the grinding material bin, and different first injection ports are connected through a first connecting cavity. This invention can be adapted to flange forks of different specifications and has strong practicality. The gap reserved in the cavity facilitates the output of Smanker abrasive flow from the nozzle to the flange fork surface for grinding. In conjunction with the pressurization pipe, the Smanker abrasive flow liquid in the workpiece cavity is efficiently discharged.

[0004] The device is designed to accommodate flange forks of different specifications by providing a sufficiently large workpiece cavity that matches the structure of the flange fork. However, in actual use, the positions of the first injection port and the flange fork are relatively fixed, and there is a certain hole spacing between the two sets of first injection holes. As a result, the Sman particles ejected from the first injection port cannot evenly cover the surface of the flange fork, affecting the grinding effect on the flange fork.

[0005] Therefore, it is necessary to invent a tooling for deburring and grinding the surface of flange forks to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a tooling for deburring and polishing the surface of a flange fork, in order to solve the problem that the Sman particles ejected from the first nozzle cannot be evenly covered on the surface of the flange fork, thus affecting the polishing effect on the flange fork.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a deburring and grinding fixture for a flange fork, comprising a grinding cylinder, an installation plate disposed inside the grinding cylinder, a flange fork body connected to the surface of the installation plate, a hydraulic cylinder fixedly installed at the center of the bottom of the grinding cylinder, the upper end of the piston rod in the hydraulic cylinder being fixedly connected to the lower surface of the installation plate, and a grinding assembly disposed at the upper end of the grinding cylinder, the grinding assembly comprising a mounting base, a housing, an electric motor, a guide pipe, a diverter pipe, a spray ring, a spray head, a rotary joint, a feed pipe, a first bevel gear, and a second bevel gear.

[0008] By adopting the above technical solution, after the flange fork body is fixed on the upper side of the mounting plate, the hydraulic cylinder is used to push the flange fork body upward. The end of the feed pipe away from the grinding cylinder is connected to a spraying device, which sprays the Sman particle stream into the grinding cylinder to grind the surface of the flange fork body.

[0015] Optionally, the device housing is fixedly connected to the upper surface of the mounting base, and both the first bevel gear and the second bevel gear are disposed on the inner side of the device housing.

[0016] By adopting the above technical solution, the equipment housing is used to protect the first bevel gear and the second bevel gear.

[0017] Optionally, a support block is fixedly connected to the upper surface of the mounting plate, and a fixing screw is fixedly connected to the middle of the support block.

[0018] By adopting the above technical solution, the support block is used to support the lower end of the flange fork body.

[0019] Optionally, the surface of the fixing screw is fitted with a sliding pressure block, and a locking screw is threadedly connected to the surface of the fixing screw on the upper side of the pressure block.

[0020] By adopting the above technical solution, the fixing screw passes through the inside of the flange fork body, presses the pressure block on the upper end of the flange fork, and tightens the locking screw to fix the flange fork body.

[0021] Optionally, a visible baffle is hinged to the front side of the grinding cylinder, and a support frame is fixedly connected to the lower end of the grinding cylinder.

[0022] By adopting the above technical solution, the visible baffle is used to seal the front side of the grinding cylinder, while allowing observation of the grinding process.

[0023] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figures 1 to 4 The fixture shown includes a grinding cylinder 1, a visible baffle 11 hinged to the front side of the grinding cylinder 1, a support frame 12 fixedly connected to the lower end of the grinding cylinder 1, a hydraulic cylinder 13 fixedly mounted at the center of the bottom of the grinding cylinder 1, a mounting plate 14 disposed inside the grinding cylinder 1, the upper end of the piston rod in the hydraulic cylinder 13 fixedly connected to the lower surface of the mounting plate 14, a flange fork body 19 connected to the surface of the mounting plate 14, and a support block 15 fixedly connected to the upper surface of the mounting plate 14. A fixing screw 16 is fixedly connected to the middle of block 15. A sliding pressure block 17 is sleeved on the surface of the fixing screw 16. A locking screw 18 is threadedly connected to the surface of the fixing screw 16 on the upper side of the pressure block 17. A grinding assembly is provided at the upper end of the grinding cylinder 1. The grinding assembly includes a mounting base 2, a housing 21, an electric motor 22, a guide pipe 23, a diverter pipe 24, a spray ring 25, a spray head 26, a rotary joint 27, a feed pipe 28, a first bevel gear 29, and a second bevel gear 210.

[0028] The visible baffle 11 is made of explosion-proof glass, which facilitates observation of the grinding process. During the grinding process, the visible baffle 11 is first opened, and the flange fork body 19 is placed on the outside of the fixing screw 16, with the lower end of the flange fork body 19 abutting against the upper end of the support block 15. Then, the pressure block 17 is placed on the surface of the fixing screw 16, with its lower end abutting against the upper end of the flange fork body 19. Finally, the locking screw 18 is threaded to the fixing screw 16 to lock and fix the pressure block 17 and the flange fork body 19, thereby improving the stability of the flange fork body 19 during the grinding process.

[0029] Next, the hydraulic cylinder 13 slowly pushes the flange fork body 19 upward. When the upper end of the flange fork body 19 moves to the inside of the spray ring 25, the spraying equipment is started. The spraying equipment delivers the Sman particle stream through the feed pipe 28, guide pipe 23 and diverter pipe 24 to the inside of the spray ring 25, and then sprays it outward through the spray head 26, so that the Sman particle stream is tightly sprayed onto the surface of the flange fork body 19, polishing the surface of the flange fork body 19 from top to bottom. The spray head 26 with different inclination angles makes it easy to spray the Sman particle stream at different angles. At the same time, the electric motor 22, the first bevel gear 29 and the second bevel gear 210 drive the spray head 26 to rotate, thereby evenly spraying the Sman particle stream onto the surface of the flange fork body 19, thus polishing different positions on the surface of the flange fork body 19, avoiding dead corners and effectively improving the polishing effect.

[0030] After the lower end of the flange fork body 19 moves to the upper side of the spray ring 25, the spraying stops. At this time, the hydraulic cylinder 13 quickly lowers the flange fork body 19 to the lowest point, and then removes the flange fork body 19 for the next grinding.

[0031] See Figure 1 and Figure 4 The mounting base 2 is fixedly connected to the center of the upper surface of the grinding cylinder 1. The guide tube 23 is rotatably connected to the center of the mounting base 2. Two sets of flow pipes 24 are fixedly connected to the lower end of the guide tube 23. The spray ring 25 is fixedly connected to the lower end of the two sets of flow pipes 24. Multiple sets of vertically inclined spray heads 26 are fixedly connected to the inner surface of the spray ring 25. A rotary joint 27 is fixedly connected to the upper end of the guide tube 23. The lower end of the feed pipe 28 is rotatably connected to the rotary joint 27. The electric motor 22 is fixedly installed on the side of the mounting base 2. The first bevel gear 29 is fixedly connected to the output end of the electric motor 22. The second bevel gear 210 is fixedly connected to the surface of the guide tube 23 at the position on the upper side of the mounting base 2. The first bevel gear 29 and the second bevel gear 210 are meshed. The equipment housing 21 is fixedly connected to the upper surface of the mounting base 2. The first bevel gear 29 and the second bevel gear 210 are both located on the inner side of the equipment housing 21.

[0032] Specifically, the Smann particle stream flows into the interior of the feed pipe 23 through the feed pipe 28, and then is guided into the interior of the spray ring 25 through the two-part diversion pipe 24. Then, it is sprayed onto the surface of the inner flange fork body 19 through the spray head 26. At the same time, the output end of the electric motor 22 drives the first bevel gear 29 to rotate, the first bevel gear 29 drives the second bevel gear 210 to rotate, the second bevel gear 210 drives the feed pipe 23 to rotate, and the feed pipe 23 drives the diversion pipe 24, the spray ring 25 and the spray head 26 to rotate, so that the Smann particle stream rotates and sprays onto the surface of the flange fork body 19.

[0033] The working principle of this utility model is as follows: The hydraulic cylinder 13 pushes the flange fork body 19 upward, while the nozzle 26 sprays Sman particles onto the surface of the flange fork body 19. The electric motor 22, the first bevel gear 29, and the second bevel gear 210 work together to drive the nozzle 26 to rotate, so that the Sman particles are evenly sprayed onto the surface of the flange fork body 19, polishing the flange fork body 19 from top to bottom, effectively improving the polishing effect on the surface of the flange fork body 19. At the same time, by using the rotating nozzle 26 to accurately spray the Sman particles onto the surface of the flange fork body 19, the utilization efficiency of the Sman particles is effectively improved, material waste is reduced, and production costs are lowered.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
