Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, and more specifically to a grinding device for the surface of oil pump parts. Background Technology

[0002] During the production, processing, and assembly of oil pumps, many of the internal components are metal parts. The metal raw materials are clamped, positioned, and milled on a lathe to obtain the required shape and size to meet the requirements of the drawings and improve the assembly accuracy of the metal parts.

[0003] When metal parts are processed, their surfaces need to be polished to improve their smoothness. Polishing can be divided into rough polishing and fine polishing. After rough polishing, the bolts need to be removed to separate the grinding wheel from the shaft. The finer grinding wheel is then installed on the shaft for fine polishing. The disassembly and assembly process takes a lot of time, which increases the intensity of the processing and greatly reduces the processing efficiency. Utility Model Content

[0029] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0030] like Figure 1-5 As shown, a surface grinding device for oil pump parts includes:

[0031] Base plate 1, with a clamping plate 2 provided on base plate 1;

[0032] Lifting unit 4 is mounted on base plate 1. Lifting unit 4 includes slide rail 48 and slide frame 41 that slides on slide rail 48.

[0033] Grinding unit 3 is mounted on slide 41 and includes fine grinding part 332, coarse grinding part 335, driving part 34 and support block 33. Fine grinding part 332 and coarse grinding part 335 are respectively mounted on both ends of support block 33. An angle adjustment rod 43 that is rotatably connected to slide 41 is mounted on support block 33.

[0034] A first cylinder 31 is provided on the support block 33. The output end of the first cylinder 31 engages with the drive component 34 to control the drive component 34 to slide on the support block 33 and engage with the fine grinding component 332 or the rough grinding component 335.

[0035] Specifically, the coarse grinding part 335 is a coarse grinding wheel, while the fine grinding part 332 is a fine grinding wheel. Both are fixed to the two ends of the support block 33. When the workpiece is installed on the clamping plate 2, the lifting unit 4 controls the slide 41 to link the coarse grinding part 335 with the grinding surface of the workpiece to perform coarse grinding. After the coarse grinding is completed, the lifting unit 4 controls the grinding unit 3 to move away from the clamping plate 2. Then, the angle adjustment rod 43 controls the support block 33 to rotate 180 degrees on the slide 41 so that the fine grinding part 332 faces the clamping plate 2. Then, the lifting unit 4 controls the fine grinding part 332 to contact the workpiece to perform the fine grinding process. Thus, the fine grinding and coarse grinding processes of the workpiece can be completed without disassembling the grinding device, thereby improving the grinding efficiency of the workpiece.

[0036] As a further embodiment provided by this utility model, both the fine grinding part 332 and the coarse grinding part 335 include a clamping plate 331 and a rotating sleeve 334 rotatably disposed on the clamping plate 331. The clamping plate 331 is fixed on the support block 33. The driving member 34 includes a clamping sleeve 343, which engages with the rotating sleeve 334. The output shaft of the driving member 34 is the clamping sleeve 343. When switching between the coarse grinding part 335 and the fine grinding part 332, the driving member 34 is moved to engage the clamping sleeve 343 with the rotating sleeve 334, thereby controlling the fine grinding part 332 or the coarse grinding part 335 to rotate through the first motor 344.

[0037] As a further embodiment provided by this utility model, one end of the rotating sleeve 334 is provided with a toothed end 333, and the sleeve 343 is provided with a groove that cooperates with the toothed end 333. When the support block 33 rotates, the drive member 34 will slide towards the grinding wheel close to the clamping plate 2. The sleeve 343 engages with the rotating sleeve 334 so that the first motor 344 controls the grinding wheel to rotate.

[0038] As a further embodiment provided by this utility model, the driving component 34 includes a first bevel gear 341, a first motor 344, and a second bevel gear 342 disposed at the output end of the first motor 344. The first bevel gear 341 is engaged with the sleeve 343 and meshes with the second bevel gear 342. The arrangement of the first bevel gear 341 and the second bevel gear 342 thereby controls the installation position of the first motor 344 to one side of the support block 33 (e.g., Figure 2 (as shown), to improve space utilization.

[0039] As a further embodiment of this utility model, a screw 337 is provided on the rotating sleeve 334, and a slider 336 is provided on the screw 337 to slide on the rotating sleeve 334. The fine grinding part 332 and the coarse grinding part 335 are respectively engaged on the slider 336. Rotating the screw 337 causes the slider 336 to slide on the rotating sleeve 334, thereby adjusting the eccentric distance between the fine grinding part 332 or the coarse grinding part 335 and the rotating sleeve 334, thereby increasing or decreasing the grinding area of ​​the fine grinding part 332 or the coarse grinding part 335.

[0040] As a further embodiment of this utility model, a second cylinder 44 is provided on the slide 41, and a rack 45 is provided at the output end of the second cylinder 44. A gear 46 is provided on the angle adjustment rod 43, and the gear 46 meshes with the rack 45. When it is necessary to switch between rough grinding and fine grinding, the rack 45 can be controlled to slide on the slide 41 by the second cylinder 44. At this time, the gear 46 rotates under the sliding drive of the rack 45, thereby controlling the support block 33 to rotate 180 degrees by the angle adjustment rod 43, thereby completing the switching between the rough grinding part 335 and the fine grinding part 332 and improving the grinding efficiency of the workpiece.

[0041] As a further embodiment of this utility model, a guide block 47 is provided on the slide 41, and the rack 45 is slidably connected to the guide block 47. The guide block 47 plays a guiding and supporting role, thereby making the rack 45 run more smoothly and improving the rotational stability of the support block 33.

[0042] As a further embodiment of this utility model, a bearing 42 is provided on the carriage 41, and the angle adjustment rod 43 is engaged with the bearing 42, thereby improving the rotation effect of the angle adjustment rod 43.

[0043] As a further embodiment of this utility model, a second motor 49 is provided on the slide rail 48. The second motor 49 controls the slide 41 to slide on the slide rail 48. The model of the first motor 344 and the second motor 49 is MHMF042L1U4-1116. The first motor 344 controls the rotation speed of the coarse grinding part 335 or the fine grinding part 332 in the grinding unit 3, while the second motor 49 controls the up and down movement of the grinding unit 3.

[0044] As a further embodiment of this utility model, clamping blocks 21 are slidably arranged in a circumferential array on the clamping disk 2. The cross-section of the clamping blocks 21 is stepped. At least four sets of clamping blocks 21 are arranged on the clamping disk 2. Furthermore, multiple sliding grooves are opened on the clamping disk 2, and the number of sliding grooves corresponds to the number of clamping blocks 21. When the workpiece is placed on the clamping disk 2, the clamping blocks 21 are made to fit against the workpiece, and then the clamping blocks 21 are fixed by bolts, thereby fixing the workpiece.
