Description

Technical Field

[0001] This utility model relates to the field of polishing technology, specifically a polishing device for the production of hydraulic cylinders. Background Technology

[0002] Polishing devices for hydraulic cylinder production are used for grinding hydraulic cylinders. The cylinder barrel of a hydraulic cylinder is a housing for the piston rod to perform reciprocating and other movements. The smoothness of the piston rod movement depends in part on the smoothness of the inner wall of the hydraulic cylinder barrel. Therefore, in the production or maintenance of hydraulic cylinder barrels, it is necessary to polish the inner wall of the hydraulic cylinder barrel to ensure the smooth movement of the piston rod. Polishing the outer surface can remove oil, impurities and residues from the surface of the hydraulic cylinder, improving the surface smoothness and flatness. This is of great significance to the performance and service life of the hydraulic cylinder. However, existing devices have certain drawbacks. For example, the polishing device for the inner wall of a hydraulic cylinder barrel described in announcement number CN216098266U includes a waste collection box for collecting waste after grinding and column legs fixed at the bottom of the waste collection box for support. A turntable is rotatably installed on the top of the waste collection box, and a fixing plate is fixed on the back of the waste collection box. The front surface of the fixing plate has at least two connecting rods vertically distributed. The other end of the connecting rod is fixed with a clamping assembly for clamping the hydraulic cylinder barrel.

[0003] While the aforementioned device can be adapted to the cylinder diameter for internal polishing, it does not polish the outer surface of the cylinder. Other devices are required to polish the outer surface of the cylinder, making overall cylinder polishing inconvenient and affecting polishing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a polishing device for hydraulic cylinder production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A polishing device for hydraulic cylinder production includes a C-shaped frame, with two rubber rollers rotatably connected to the inner surface of the C-shaped frame, and a limit rod fixedly connected to the upper surface of the C-shaped frame near the rear surface.

[0007] An inner grinding module is slidably connected to the outer surface of the limiting rod, and an outer grinding module is movably connected to the upper surface of the C-shaped frame. The inner grinding module includes a sliding seat and a connecting seat. The sliding seat is slidably connected to the outer surface of the limiting rod, and the connecting seat is movably connected to the front side of the sliding seat. A No. 1 connecting bolt is rotatably connected to the rear surface of the connecting seat, and the No. 1 connecting bolt is threadedly connected to the sliding seat. The outer grinding module includes a limiting frame, a limiting wheel, and a hydraulic cylinder. The limiting frame is movably connected to the upper surface of the C-shaped frame, the limiting wheel is rotatably connected to the lower surface of the limiting frame, and the hydraulic cylinder is fixedly connected to the upper surface of the C-shaped frame. The output end of the hydraulic cylinder is fixedly connected to the limiting frame.

[0008] Furthermore, a brush holder is fixedly connected to the inner surface of the C-shaped frame, brush bristles are fixedly connected inside the brush holder, and a box door is rotatably connected to the outer surface of the C-shaped frame.

[0009] Furthermore, the number of rubber rollers is two, and a motor is fixedly connected to the front surface of the C-shaped frame, with the motor and one of the rubber rollers being fixedly connected.

[0010] Furthermore, the brush bristles and the rubber roller are in close contact, and the motor can scrape the rubber roller.

[0011] Furthermore, the internal grinding module also includes a hinge rod, a connecting rod, and a cross body. The hinge rod is hinged to the upper and lower surfaces of the connecting seat. One end of the hinge rod is hinged to an installation sleeve. A grinding strip is detachably connected to the lower surface of the installation sleeve. The connecting rod is hinged to the front surface of the sliding seat. The connecting rod and the hinge rod are hinged together. The cross body is fixedly connected to the front surface of the connecting seat.

[0012] Furthermore, the mounting sleeve and the cross body are slidably connected, and the cross body can limit the movement of the mounting sleeve.

[0013] Furthermore, the external grinding module also includes a limiting post, a second connecting bolt, and a second grinding strip. The limiting post is embedded and movably connected to the upper surface of the C-shaped frame. The lower end of the limiting post is fixedly connected to a snap-fit ​​seat. The second connecting bolt is rotatably connected to the upper surface of the snap-fit ​​seat. The second connecting bolt and the C-shaped frame are threaded together. The second grinding strip is embedded and connected to the lower surface of the snap-fit ​​seat.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The change in distance between the connecting seat and the sliding seat causes the connecting seat to move the hinge rod, which in turn applies force to the mounting sleeve in conjunction with the connecting rod. This causes the mounting sleeve to expand or contract outward along the cross body, making the No. 1 grinding strip suitable for cylinders with different inner diameters.

[0016] 2. Start the motor. The output end of the motor is fixedly connected to one of the rubber rollers, causing the rubber roller to drive the cylinder to rotate. At this time, rotate the second connecting bolt. Under the push of the thread, the snap-fit ​​seat and the limit post descend along the C-shaped frame, so that the second grinding strip contacts the outer surface of the cylinder. This allows the inner and outer walls of the cylinder to be ground simultaneously, ensuring the polishing efficiency of the cylinder. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 In this embodiment of the utility model, a polishing device for hydraulic cylinder production includes a C-shaped frame 1, with two rubber rollers 2 rotatably connected to the inner surface of the C-shaped frame 1, and a limit rod 3 fixedly connected to the upper surface of the C-shaped frame 1 near the rear surface.

[0024] The outer surface of the limiting rod 3 is slidably connected to the inner grinding module 4, and the upper surface of the C-shaped frame 1 is embedded and movably connected to the outer grinding module 5. The inner grinding module 4 includes a sliding seat 401 and a connecting seat 402. The sliding seat 401 is slidably connected to the outer surface of the limiting rod 3, and the connecting seat 402 is movably connected to the front side of the sliding seat 401. The rear surface of the connecting seat 402 is rotatably connected to a first connecting bolt 403. The first connecting bolt 403 and the sliding seat 401 are threadedly connected. The outer grinding module 5 includes a limiting frame 501, a limiting wheel 502, and a hydraulic cylinder 503. The limiting frame 501 is embedded and movably connected to the upper surface of the C-shaped frame 1, the limiting wheel 502 is rotatably connected to the lower surface of the limiting frame 501, and the hydraulic cylinder 503 is embedded and fixedly connected to the upper surface of the C-shaped frame 1. The output end of the hydraulic cylinder 503 is fixedly connected to the limiting frame 501.

[0025] Specifically, the cylinder 6 is placed on the upper surface of the rubber rollers 2, with the two rubber rollers 2 supporting the cylinder 6. Later, the door 103 is opened to clean the inside of the U-shaped frame 1. The brush bristles 102 contact the rubber rollers 2, and the rotation of the rubber rollers 2 brushes the grinding debris from the rubber rollers 2 into the inside of the U-shaped frame 1. Driven by the threads, the locking seat 504, in conjunction with the limiting post 505, descends along the U-shaped frame 1, causing the second grinding strip 507 to contact the outer surface of the cylinder 6. The inner and outer walls of the cylinder 6 are polished simultaneously to ensure the polishing efficiency of the cylinder 6. The distance between the connecting seat 402 and the sliding seat 401 changes, causing the connecting seat 402 to drive the hinge rod 404 to move. The hinge rod 404, in conjunction with the connecting rod 405, applies force to the mounting sleeve 407, causing the mounting sleeve 407 to expand or contract outward along the cross body 406 under force, so that the first polishing strip 408 can be used for cylinders 6 with different inner diameters.

[0026] Example 1

[0027] like Figure 1-4 As shown, a brush holder 101 is fixedly connected to the inner surface of the C-shaped frame 1, and brush bristles 102 are fixedly connected inside the brush holder 101. A door 103 is rotatably connected to the outer surface of the C-shaped frame 1. The brush bristles 102 are in close contact with the rubber roller 2, and the motor 201 can scrape the rubber roller 2.

[0028] In this embodiment, the cylinder 6 is placed on the upper surface of the rubber roller 2, and the two rubber rollers 2 support the cylinder 6. Later, the box door 103 is opened to clean the inside of the C-shaped frame 1. The brush bristles 102 contact the rubber roller 2, and the rotation of the rubber roller 2 can brush the grinding waste on the rubber roller 2 into the inside of the C-shaped frame 1.

[0029] like Figure 1-4As shown, the internal grinding module 4 also includes a hinge rod 404, a connecting rod 405, and a cross body 406. The hinge rod 404 is hinged to the upper and lower surfaces of the connecting seat 402. One end of the hinge rod 404 is hinged to a mounting sleeve 407. A first grinding strip 408 is detachably connected to the lower surface of the mounting sleeve 407. The connecting rod 405 is hinged to the front surface of the sliding seat 401. The connecting rod 405 and the hinge rod 404 are hinged together. The cross body 406 is fixedly connected to the front surface of the connecting seat 402. The mounting sleeve 407 and the cross body 406 are slidably connected. The cross body 406 can limit the movement of the mounting sleeve 407.

[0030] In this embodiment, when grinding the inside of the cylinder 6, the first connecting bolt 403 is manually rotated. Under the push of the thread, the distance between the connecting seat 402 and the sliding seat 401 changes, causing the connecting seat 402 to drive the hinge rod 404 to move. The hinge rod 404, in conjunction with the connecting rod 405, applies force to the mounting sleeve 407, causing the mounting sleeve 407 to expand or contract outward along the cross body 406. This allows the first grinding strip 408 to be suitable for cylinders 6 with different inner diameters. The mounting sleeve 407 and the first grinding strip 408, as well as the sliding seat 401 and the limiting rod 3, are detachably connected by bolts, facilitating manual adjustment later.

[0031] Example 2

[0032] Based on Embodiment 1, in order to overcome the problem that it is inconvenient to clamp the outer surface of the cylinder 6 in Embodiment 1.

[0033] like Figure 1-4 As shown, the external grinding module 5 also includes a limiting post 505, a second connecting bolt 506, and a second grinding strip 507. The limiting post 505 is embedded and movably connected to the upper surface of the C-shaped frame 1. The lower end of the limiting post 505 is fixedly connected to a snap-fit ​​seat 504. The second connecting bolt 506 is rotatably connected to the upper surface of the snap-fit ​​seat 504. The second connecting bolt 506 and the C-shaped frame 1 are threaded together. The second grinding strip 507 is embedded and connected to the lower surface of the snap-fit ​​seat 504.

[0034] In this embodiment, the hydraulic cylinder 503 is activated, and the output end of the hydraulic cylinder 503 drives the limiting frame 501 to descend, so that the limiting wheel 502 at the end of the limiting frame 501 contacts the outer surface of the cylinder body 6. This allows the rubber roller 2 to limit the cylinder body 6. The motor 201 is then activated, and the output end of the motor 201 is fixedly connected to one of the rubber rollers 2, causing the rubber roller 2 to drive the cylinder body 6 to rotate. At this time, the second connecting bolt 506 is rotated, and under the push of the thread, the snap-fit ​​seat 504 and the limiting post 505 descend along the U-shaped frame 1, so that the second grinding strip 507 contacts the outer surface of the cylinder body 6. This allows the inner and outer walls of the cylinder body 6 to be ground simultaneously, ensuring the polishing efficiency of the cylinder body 6.
