[0002] A search revealed Chinese Patent Publication No. CN218658356U, which discloses a polishing device for the inner wall of a cylinder barrel in hydraulic cylinder production. This invention utilizes a bidirectional lead screw transmission structure and a rotating shaft connecting the two ends of a push rod to the transmission sleeve and the outer side of the polishing plate, respectively. The operator simply pushes the bidirectional lead screw to rotate, causing the two sets of transmission sleeves to move synchronously towards each other and vertically relative to each other. This, in turn, causes the polishing plates located on both sides of the rotating tube to move horizontally, adjusting their spacing. This ensures the polishing plates can fit the inner wall of hydraulic cylinder barrels of different inner diameters for polishing, improving the overall practicality of the polishing device. The existing technology described above has the following drawbacks: it lacks a self-cleaning structure, allowing dust generated during polishing to easily disperse into the air, affecting the health of workers.

[0010] (III) Beneficial Effects Compared with the prior art, this utility model provides a high-efficiency polishing device for the inner wall of the cylinder barrel in the production of hydraulic cylinders, which has the following beneficial effects: 1. This high-efficiency polishing device for the inner wall of the cylinder barrel in the production of hydraulic cylinders, through the setting of adjustment mechanism and fixing mechanism, starts a dual-axis servo motor, whose two output shafts drive the threaded rod to rotate. Since the threaded block is threadedly connected to the threaded rod, and the threaded block is restricted to moving only left and right within the box due to the inner wall of the box, the rotation of the threaded rod will cause the threaded block to drive the support plate two to move left and right, thereby adjusting the distance between the two fixing mechanisms so that the cylinder barrel to be polished can be accurately placed in the appropriate position for polishing. The cylinder barrel to be polished is placed on the two trays of the U-shaped seat. Insert the connecting block into the second support plate, allowing the clamping rod to extend to the rear of the U-shaped seat, initially limiting the U-shaped seat and preventing it from moving back and forth during polishing. Pull the pull rod upward, causing the lifting plate to slide upward inside the column, while simultaneously stretching the fixing spring. After the cylinder is placed, release the pull rod. Under the elastic force of the fixing spring, the lifting plate drives the pressure block to move downward, pressing the cylinder and fixing it to prevent it from shaking during polishing. The limiting block prevents the lifting plate from sliding out of the column, achieving the purpose of adjusting the fixing structure according to the cylinder diameter.

[0011] 2. This high-efficiency polishing device for the inner wall of the cylinder barrel in the production of hydraulic cylinders is equipped with a collection mechanism, a cleaning mechanism, a striking mechanism, and a collection frame. When the suction fan is started, a negative pressure is created inside the collection cylinder. Debris and dust generated during polishing enter the collection cylinder through the feeding screen. The screen prevents larger debris from entering the connecting pipe and damaging the suction fan, thus achieving the collection of debris and dust. The rotary motor starts, driving the rotating shaft to rotate. The drive wheel on the shaft rotates accordingly. Because the drive wheel meshes with the driven wheel, the driven wheel drives the rotating rod to rotate. The cleaning brush on the rotating rod rotates accordingly, cleaning the bottom of the feeding screen to prevent debris from clogging it and ensuring smooth feeding. The guide block is fitted on the outside of the rotating rod to guide the material from the bottom of the cylinder. The debris falling from the feed screen acts as a guide, allowing it to fall smoothly into the collection frame. When the shaft rotates, it drives the cam to rotate. When the cam's protrusion contacts the rectangular plate, it pushes the rectangular plate upward. The rectangular plate, through the upright, drives the sliding plate to slide upward on the mounting frame, simultaneously stretching the return spring. The striking block at the top of the sliding plate moves accordingly and strikes the outside of the collection cylinder. When the cam's protrusion leaves the rectangular plate, under the contraction force of the return spring, the sliding plate drives the striking block to move downward and reset. As the cam continues to rotate, the striking block periodically strikes the collection cylinder, causing the debris adhering to the inner wall of the collection cylinder to vibrate and fall off, further improving the collection effect and achieving the purpose of having a self-cleaning structure.

According to the diameter of the cylinder, start the electric telescopic rod 208, adjust the degree of unfolding of the polishing plate 210, start the electric telescopic rod 208, and push the top strip 212 up and down. Since the two strips 212 are connected by a vertical plate 213, and the round rod 214 on the front side of the strip 212 is slidably connected to the moving plate 211, the movement of the top strip 212 will cause the round rod 214 to slide within the moving plate 211, thereby causing the connecting plate 209 to drive the polishing plate 210 to slide on the mounting column 206, realizing the expansion or contraction of the polishing plate 210 to fit the inner wall of cylinders of different diameters. Start the dual-axis servo motor 32, adjust the position of the fixing mechanism 4 so that the U-shaped seat 401 is in a suitable position, place the cylinder to be polished on the two support plates 402 of the U-shaped seat 401, insert the connecting block 403 into the support plate 35, so that the locking rod 404 extends to the rear side of the U-shaped seat 401, pull the pull rod 410 upward, and release the pull rod 410 after placing the cylinder. 10. Press the cylinder with the pressure block 408 to complete the cylinder fixing. Start the electric push rod 202 and adjust the height of the polishing plate 210 so that it is close to the top of the inner wall of the cylinder. Start the motor 205 to drive the polishing plate 210 to rotate. Start the electric push rod 202 again to slowly move the polishing plate 210 downward to polish the inner wall of the cylinder. During the polishing process, the moving speed of the electric push rod 202 and the rotation speed of the motor 205 can be adjusted as needed. Start the suction fan 53 to suck the debris and dust generated during the polishing process into the collection cylinder 51. Start the rotary motor 602 to drive the cleaning brush 606 to rotate and clean the feeding screen 52. At the same time, the cam 611 drives the striking block 73 to periodically strike the collection cylinder 51 to ensure that the debris falls smoothly into the collection frame 8.

[0023] After polishing is complete, turn off the electrical components such as motor 205, electric push rod 202, suction fan 53 and rotary motor 602, pull the pull rod 410 upward, remove the pressure block 408, remove the connecting block 403 from the support plate 35, remove the polished cylinder, open the box door 9 on the front side of the bottom box 1, take out the collection frame 8, clean up the collected debris, then put the collection frame 8 back in its original position, close the box door 9, and complete the entire polishing work.

[0025] In summary, this high-efficiency polishing device for the inner wall of the cylinder in the production of hydraulic cylinders, through the setting of adjustment mechanism 3 and fixing mechanism 4, starts the dual-axis servo motor 32, whose two output shafts drive the threaded rod 33 to rotate. Since the threaded block 34 is threadedly connected to the threaded rod 33, and the threaded block 34 is restricted to moving only left and right within the box 31 by the inner wall of the box 31, the rotation of the threaded rod 33 will cause the threaded block 34 to drive the support plate 2 35 to move left and right, thereby adjusting the distance between the two fixing mechanisms 4 so that the cylinder to be polished can be accurately placed in the appropriate position for polishing. The cylinder to be polished is placed on the two support plates 402 of the U-shaped seat 401, and the connecting block 403 is inserted into the support plate 2 35, so that the clamping rod 404 extends to the rear side of the U-shaped seat 401. The U-shaped seat 401 is initially limited to prevent it from moving back and forth during polishing. Pulling the lever 410 upwards causes the lifting plate 407 to slide upwards within the column 406, simultaneously stretching the fixing spring 412. After the cylinder is positioned, the lever 410 is released. Under the elastic force of the fixing spring 412, the lifting plate 407 moves the pressure block 408 downwards, pressing the cylinder to secure it and prevent it from shaking during polishing. The limiting block 411 prevents the lifting plate 407 from sliding out of the column 406, achieving the purpose of adjusting the fixing structure according to the cylinder diameter. By setting up the collection mechanism 5, cleaning mechanism 6, tapping mechanism 7, and collection frame 8, the suction fan 53 is started, creating negative pressure within the collection cylinder 51 to trap the debris generated during polishing. Dust and debris enter the collection cylinder 51 through the feeding screen 52. The partition screen 55 prevents larger debris from entering the connecting pipe 54 and damaging the suction fan 53, thus achieving the collection of debris and dust. The rotary motor 602 starts, driving the rotating shaft 607 to rotate. The drive wheel 609 on the rotating shaft 607 rotates accordingly. Since the drive wheel 609 meshes with the driven wheel 610, the driven wheel 610 drives the rotating rod 604 to rotate. The cleaning brush 606 on the rotating rod 604 rotates accordingly, cleaning the bottom of the feeding screen 52 to prevent debris from clogging the feeding screen 52 and ensuring smooth feeding. The guide block 612 is fitted on the outside of the rotating rod 604 and can guide the debris falling from the feeding screen 52, allowing the debris to fall smoothly into the collection frame 8. When the rotating shaft 607 rotates, it drives the convex... When wheel 611 rotates, and the protruding part of cam 611 contacts rectangular plate 75, it pushes rectangular plate 75 upward. Rectangular plate 75 drives slide plate 72 upward on mounting bracket 71 via upright rod 74, simultaneously stretching return spring 77. The striking block 73 on top of slide plate 72 moves accordingly and strikes the outside of collection cylinder 51. When the protruding part of cam 611 leaves rectangular plate 75, under the contraction force of return spring 77, slide plate 72 drives striking block 73 downward to reset. As cam 611 continues to rotate, striking block 73 periodically strikes collection cylinder 51, causing debris adhering to the inner wall of collection cylinder 51 to vibrate and fall, further improving the collection effect. This achieves the purpose of having a self-cleaning structure and solves the problem of not having a self-cleaning structure.The dust generated during polishing is easily dispersed into the air, affecting the health of workers. Furthermore, the inability to adjust the fixing structure according to the cylinder diameter reduces the practicality of the equipment.
