Description

Technical Field

[0001] The present application relates to the technical field of polishing machines, and more specifically, to an automatic outer wall polishing machine for a stainless steel piston rod. Background Art

[0002] As we all know, a polishing machine is a mechanical equipment used to polish and grind the surface of various materials. Its main function is to remove burrs and other undesirable substances on the surface of the material to make the surface of the material flat and smooth. Its principle is mostly to drive the polishing wheel at high speed through the drive of the motor. The contact between the polishing wheel and the surface of the material produces a large friction to polish its surface. After the stainless steel piston rod is produced, its surface also needs to be ground and polished. Therefore, the polishing machine plays an important role in the production of stainless steel piston rods.

[0003] However, most of the polishing machines currently on the market require workers to hold them for polishing, which will cause the workers to be very tired after a long time of polishing, thus delaying the progress of the polishing work and greatly reducing the efficiency of the polishing work. Utility Model Content

[0004] In order to solve the above problems, the present application provides an automatic outer wall polishing machine for a stainless steel piston rod.

[0005] The present application provides an automatic outer wall polishing machine for a stainless steel piston rod, which adopts the following technical solution: an automatic outer wall polishing machine for a stainless steel piston rod, comprising a workbench and a moving block, the top of the workbench is fixedly connected to a frame, the inner wall of the frame is fixedly connected to a motor, the output end of the motor is fixedly connected to a first threaded rod through a coupling, the outer wall of the first threaded rod is fixedly sleeved with a first gear, the top of the moving block is fixedly connected to a grinding plate, and the inner wall of the grinding plate is fixedly connected to a sanding belt.

[0006] The inner side wall of the frame is threadedly sleeved with a second threaded rod, one end of the second threaded rod is inlaid with a bearing, the outer ring of the bearing is fixedly connected to a second clamping plate, the inner side wall of the frame is rotatably connected to a rotating rod, the outer wall of the rotating rod is fixedly sleeved with a second gear, and one end of the rotating rod is fixedly connected to the first clamping plate.

[0007] Furthermore, the grinding plate is in an arc-shaped structure, and the moving block is threadably sleeved with the first threaded rod.

[0008] Through the above technical solution, the starting motor drives the first threaded rod to rotate, so that the moving block drives the sanding belt to grind and polish the bottom of the piston rod.

[0009] Furthermore, one end of the first clamping plate is fixedly connected to a first suction cup, and one side of the second clamping plate is fixedly connected to a second suction cup.

[0010] Through the above technical solution, the first suction cup and the second suction cup adsorb the two end surfaces of the piston rod, thereby helping to improve the stability of the piston rod.

[0011] Furthermore, a handle is fixedly connected to the other end of the second threaded rod, and the second gear is meshingly connected to the first gear.

[0012] Through the above technical solution, since the first gear is meshed with the second gear, the rotation of the first threaded rod can drive the first clamping plate to rotate.

[0013] Furthermore, a sliding block is fixedly connected to the bottom of the moving block, and a slideway is provided on the top of the workbench.

[0014] Through the above technical solution, the moving block can drive the grinding plate and the sanding belt to move.

[0015] Furthermore, the frame is in an inverted "U"-shaped structure, and the outer wall of the slider is slidably connected to the inner wall of the slideway.

[0016] Through the above technical solution, the moving block can only move horizontally and will not rotate.

[0017] In summary, the present application includes at least one of the following beneficial technical effects:

[0018] (1) After the piston rod is fixed by setting a motor, a first threaded rod, a moving block and a sanding belt, the motor is started to drive the first threaded rod to rotate, so that the moving block drives the sanding belt to grind and polish the bottom of the piston rod. Since the first gear and the second gear are meshed and connected, the rotation of the first threaded rod can drive the piston rod to rotate, so that the sanding belt grinds and polishes the entire outer wall of the piston rod, thereby realizing that the device does not need to be held by the staff for polishing work, which brings great convenience to the staff, and does not delay the progress of the polishing work, thereby greatly improving the efficiency of the polishing work.

[0019] (2) By setting the first clamping plate, the second threaded rod, the second clamping plate and the second suction cup, the piston rod to be polished is placed between the first clamping plate and the second clamping plate. Then, the second threaded rod is rotated to drive the second clamping plate to move, so that the piston rod can be clamped and fixed. The second threaded rod can be rotated to adjust the position of the second clamping plate, so that piston rods of different lengths can be clamped and fixed, thereby further meeting the use requirements of the device and being worthy of promotion.

Figure 1-4 , including a workbench 1 and a moving block 7, the top of the workbench 1 is fixedly connected to a frame 2, the inner wall of the frame 2 is fixedly connected to a motor 3, the output end of the motor 3 is fixedly connected to a first threaded rod 4 through a coupling, the outer wall of the first threaded rod 4 is fixedly sleeved with a first gear 10, the top of the moving block 7 is fixedly connected to a grinding plate 8, and the inner wall of the grinding plate 8 is fixedly connected to a sanding belt 9.

[0031] A second threaded rod 15 is threadedly sleeved on the inner wall of the frame 2, and a bearing 19 is inlaid at one end of the second threaded rod 15. The outer ring of the bearing 19 is fixedly connected to a second clamping plate 17. The inner wall of the frame 2 is rotatably connected to a rotating rod 11, and a second gear 12 is fixedly sleeved on the outer wall of the rotating rod 11. One end of the rotating rod 11 is fixedly connected to a first clamping plate 13. After the piston rod is fixed, the motor 3 is started to drive the first threaded rod 4 to rotate, so that the moving block 7 drives the sanding belt 9 to grind and polish the bottom of the piston rod. Since the first gear 10 and the second gear 12 are meshed and connected, the rotation of the first threaded rod 4 can drive the piston rod to rotate, so that the sanding belt 9 grinds and polishes the entire outer wall of the piston rod, thereby realizing that the device does not require the staff to hold it for polishing work, which brings great convenience to the staff and will not delay the progress of the polishing work, thereby greatly improving the efficiency of the polishing work.

[0032] In this embodiment, the grinding plate 8 is in the shape of an arc structure, and the moving block 7 is threadedly connected with the first threaded rod 4. The starting motor 3 drives the first threaded rod 4 to rotate, so that the moving block 7 drives the sanding belt 9 to grind and polish the bottom of the piston rod.

[0033] In this embodiment, a first suction cup 14 is fixedly connected to one end of the first clamping plate 13, and a second suction cup 18 is fixedly connected to one side of the second clamping plate 17. The first suction cup 14 and the second suction cup 18 adsorb the two end surfaces of the piston rod, thereby helping to improve the stability of the piston rod.

[0034] In this embodiment, the other end of the second threaded rod 15 is fixedly connected to a handle 16, and the second gear 12 is meshedly connected to the first gear 10. Since the first gear 10 and the second gear 12 are meshedly connected, the rotation of the first threaded rod 4 can drive the first clamping plate 13 to rotate.

[0035] In this embodiment, a slider 5 is fixedly connected to the bottom of the moving block 7, and a slideway 6 is provided on the top of the workbench 1. The moving block 7 can drive the grinding plate 8 and the sanding belt 9 to move.

[0036] In this embodiment, the frame 2 is in the shape of an inverted "U"-shaped structure, and the outer wall of the slider 5 is slidably connected to the inner wall of the slideway 6, so that the moving block 7 can only move horizontally and cannot rotate.

[0037] The implementation principle of the automatic outer wall polishing machine for a stainless steel piston rod in the embodiment of the present application is as follows: first, the piston rod to be polished is placed between the first clamping plate 13 and the second clamping plate 17, and then the second threaded rod 15 is rotated to drive the second clamping plate 17 to move, thereby clamping and fixing the piston rod;

[0038] Secondly, the outer wall of the piston rod contacts the inner wall of the abrasive belt 9, and the starting motor 3 drives the first threaded rod 4 to rotate. Since the first gear 10 and the second gear 12 are meshed and connected, the rotation of the first threaded rod 4 can drive the first clamping plate 13 to rotate, and then drive the piston rod to rotate;

[0039] Finally, since the first threaded rod 4 is threadedly connected with the moving block 7, the moving block 7 will move, so that the sanding belt 9 can automatically grind and polish the outer wall of the piston rod comprehensively, without the need for manual grinding by the staff.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
