Description

Technical Field

[0001] This utility model relates to the technical field of precision grinding devices for parts processing, specifically a precision grinding device for parts processing. Background Technology

[0002] With social development, continuous technological progress, and the continuous improvement of economic level, people's living conditions are getting better and better, and more and more cars are used for transportation. As cars become more affordable, the competition in the auto parts processing market is becoming increasingly fierce. In the process of processing automotive shaft parts, the surface of the shaft wall may be rough or uneven. Such shaft parts will have a significant impact on subsequent processing and production. Currently, most shaft parts are polished manually, which is time-consuming, labor-intensive, and produces poor polishing results.

[0003] Existing precision grinding equipment for parts machining typically requires fixing in a designated position during use. To improve the fixing effect, special fixing fixtures are often required, which increases production costs and necessitates frequent fixture changes for different parts, which is inconvenient. Furthermore, the actual grinding process of existing precision grinding equipment usually involves using a grinding disc with sandpaper attached, but this method can only grind flat surfaces, making it inconvenient for grinding irregularly shaped surfaces. If the workpiece surface has grooves, it is even more difficult to grind them, requiring manual grinding later. Therefore, existing precision grinding equipment for parts machining has the disadvantages of being convenient for clamping and fixing irregularly shaped parts and for machining curved and grooved surfaces.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1

[0030] This utility model provides a technical solution: a precision grinding device for parts processing, including a worktable 1, a sliding groove 2 on the upper surface of the worktable 1, a bidirectional motor 3 fixedly connected to the inner wall of the worktable 1, a lead screw 4 fixedly connected to one end of the output shaft of the bidirectional motor 3, the outer surface of the lead screw 4 being drivenly connected to the inner wall of the slider 5, the slider 5 being slidably connected to the inner wall of the sliding groove 2, a movable frame 6 fixedly connected to the upper surface of the slider 5, a rotating column 7 rotatably connected to the inner wall of the movable frame 6, and a crank handle 8 fixedly connected to the right end of the rotating column 7. Two crank handles 8 are provided and are positioned opposite each other. The rotating column 7 is fixedly connected to an air supply block 9 at one end, and a clamping module housing 10 is fixedly connected to the other end of the air supply block 9. A limiting groove 11 is provided on the inner side wall of the clamping module housing 10. Several limiting grooves 11 and clamping rods 12 are provided and evenly distributed in a rectangular array. A sealing ring 13 is detachably connected to the outer surface of the right end of the clamping rod 12. The outer surface of the sealing ring 13 is slidably connected to the inner side wall of the limiting groove 11. The clamping rod 12 is slidably connected to the inner side wall of the limiting groove 11. A copper ball 15 is detachably connected to one end of the clamping rod 12 through an insert rod 14.

[0031] To facilitate the clamping and fixing of irregularly shaped parts, as shown in the attached document... Figures 1 to 7As shown, this application adopts the following structure: through the arrangement of air supply block 9, clamping module housing 10, clamping rod 12, insertion rod 14, copper ball 15 and hydraulic pump 29, the precision grinding device for part processing has the effect of facilitating the clamping and fixing of irregularly shaped parts. In use, by controlling the operation of bidirectional motor 3, the lead screw 4 is driven to rotate, driving slider 5 to slide left and right inside sliding groove 2, thereby adjusting the position of two moving frames 6. When the two moving frames 6 approach each other, they drive the clamping module housing 10 to approach each other. At this time, the copper balls 15 at the ends of several clamping rods 12 abut against the outer surface of the workpiece, and according to their own shape, the clamping rods 12 are compressed and tightened inside the clamping module housing 10. The hydraulic pump 29 pumps liquid into the inside of the conveying wheel 19. The pressure inside the clamping module housing 10 is increased by pressing the oil, which in turn causes the clamping rods 12, which retract into the clamping module housing 10, to exert an outward force to clamp the workpiece. Since the clamping module housing 10 has several interconnected limiting grooves 11, each clamping rod 12 experiences the same thrust. The copper ball 15 reduces the squeezing damage to the workpiece surface caused by the hardness of the clamping tool when clamping the workpiece. In other words, through the coordinated arrangement of the clamping module housing 10, clamping rods 12, insert rods 14, and copper ball 15, workpieces of different shapes and sizes can be clamped and fixed during use. Especially for irregularly shaped workpieces, it increases the contact area between the clamp and the outer surface of the workpiece, thereby achieving the purpose of facilitating the clamping and fixing of irregularly shaped parts.

[0032] Example 2

[0033] This utility model provides the following technical solution: A first electric slide rail 16 is fixedly connected to the upper surface of the workbench 1; a second electric slide rail 17 is fixedly connected to the outer surface of the slider 5 of the first electric slide rail 16; a grinding module mounting bracket 18 is fixedly connected to the lower surface of the slider 5 of the second electric slide rail 17; a shaft is rotatably connected to the inner wall of the grinding module mounting bracket 18; two conveyor wheels 19 and two shafts are provided and distributed vertically; a motor is fixedly connected to the rear of the grinding module mounting bracket 18; one end of the motor's output shaft is fixedly connected to the rear end of the lower shaft; a conveyor wheel 19 is rotatably connected to the front of the grinding module mounting bracket 18 via a shaft; a housing 20 is fixedly connected to the front of the grinding module mounting bracket 18 below the conveyor wheel 19; and a shaft is rotatably connected to the upper surface of the housing 20. The first driven rotating wheel 21 is rotatably connected to the lower surface of the housing 20 via a shaft, and the inner wall of the housing 20 is slidably connected to a telescopic plate 22. The inner side of the lower surface of the telescopic plate 22 is rotatably connected to a rotating roller 26 via a shaft. Several telescopic plates 22 are arranged in a rectangular array and evenly distributed. The inner wall of the housing 20 is slidably connected to a push plate 24. The upper surface of the push plate 24 is fixedly connected to a spring 25. The upper end of the spring 25 is fixedly connected to the inner top wall of the housing 20. Steel balls 23 are arranged between the inner wall of the housing 20 and the lower surface of the push plate 24. The outer surface of the conveyor wheel 19 is connected to a grinding belt 28. The upper surface of the worktable 1 is fixedly connected to a hydraulic pump 29. The output end of the hydraulic pump 29 is fixedly connected to the outer surface of the air supply block 9 via a spring 25 tube.

[0034] To facilitate the machining of curved and grooved parts surfaces, as shown in the attached... Figures 1 to 7As shown, this application adopts the following structure. Through the arrangement of the housing 20, telescopic plate 22, steel ball 23, push plate 24, spring 25, and rotating roller 26, the precision grinding device for part processing achieves the effect of easily processing the surfaces of curved and grooved parts. In actual use, the first electric slide rail 16 and the second electric slide rail 17 respectively control the height and front-to-back distance of the grinding device. After clamping the workpiece, the position is adjusted by the first electric slide rail 16 and the second electric slide rail 17 so that the lower surface of the grinding belt 28 abuts against the upper surface of the workpiece. Then, the motor at the rear end of the transmission wheel 19 drives the transmission wheel 19 to rotate, thereby driving the grinding belt 28 to travel between the two transmission wheels 19, the outer surface of the first driven wheel 21, and the outer surface of the second driven wheel 27, thus grinding the workpiece. When grinding irregularly shaped workpieces, as the second electric slide rail 17 descends, the lower surface of the grinding belt 28... The surface of the workpiece is pressed against the upper surface of the telescopic piece 22, which in turn presses against the rotating roller 26 on the lower surface of the telescopic piece 22. The telescopic piece 22 is compressed and retracts into the interior of the housing 20. The arrangement of several telescopic pieces 22 can well adapt to irregularly shaped workpieces, allowing the grinding belt 28 on the lower side to better fit the upper surface of the workpiece. The spring 25 pushes the push plate 24 downward, squeezing the steel ball 23 inside the housing 20. The arrangement of the steel ball 23 allows several telescopic pieces 22 to be evenly stressed while extending to different lengths. That is, through the coordinated arrangement of the housing 20, telescopic piece 22, steel ball 23, push plate 24, spring 25 and rotating roller 26, during use, the outer surface of the grinding belt 28 can better fit the outer surface of the workpiece for grinding, and the grinding belt 28 can be pushed into grooves and ravines for grinding, thereby achieving the purpose of facilitating the processing of curved and grooved parts.

[0035] 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 equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
