Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic cylinder processing, in particular to a grinding device for hydraulic cylinder processing. Background Art

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has the advantages of simple structure and reliable operation. When a hydraulic cylinder is used to achieve reciprocating motion, a deceleration device can be eliminated, and there is no transmission gap and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various machines. A hydraulic cylinder basically consists of a cylinder liner, a cylinder head, a piston, a piston rod, a sealing device, a buffer device and an exhaust device.

[0003] At present, after the cylinder liner of the hydraulic cylinder is processed, in order to ensure the matching accuracy between its inner wall and the piston, the inner wall of the hydraulic cylinder liner needs to be polished. In the existing technology, the polishing of the inner wall of the hydraulic cylinder liner is mostly achieved with the help of a polishing machine. When the existing polishing machine works, the driving mechanism drives the polishing mechanism to rotate and move inside the hydraulic cylinder liner. When the polishing mechanism rotates and moves, it acts on the inner wall of the hydraulic cylinder liner to achieve the polishing of the inner wall of the hydraulic cylinder liner. However, during the polishing process, a large amount of debris will inevitably fall off from the inner wall of the hydraulic cylinder liner. After the debris falls off, it still adheres to the inner wall of the hydraulic cylinder liner, thereby affecting the subsequent polishing of the inner wall of the hydraulic cylinder liner, resulting in poor polishing effect of the inner wall of the hydraulic cylinder liner, which is in urgent need of improvement.

When the collecting grinding assembly 30 rotates and reciprocates, it acts on the inner wall of the hydraulic cylinder liner to be ground, so as to grind the inner wall of the hydraulic cylinder liner to be ground and collect debris generated during grinding.

[0044] When the inner wall of the hydraulic cylinder liner needs to be polished, the hydraulic cylinder liner to be polished can be placed above the base plate 10, and then the hydraulic cylinder liner to be polished is positioned by the positioning component 20, and then the collecting polishing component 30 is driven by the first driving component 40 to rotate inside the hydraulic cylinder liner to be polished, and the collecting polishing component 50 is driven by the second driving component 50 to move back and forth inside the hydraulic cylinder liner to be polished along the length direction of the hydraulic cylinder liner. When the collecting polishing component 30 rotates and reciprocates, it polishes the inner wall of the hydraulic cylinder liner to be polished, and at the same time collects the debris generated during polishing, so as to prevent the debris from adhering to the inner wall of the hydraulic cylinder liner to be polished, thereby avoiding the debris affecting the polishing effect.

[0045] See also Figure 1 、 Figure 4 as well as Figure 7In one embodiment, the collecting grinding assembly 30 includes a collecting cylinder 301 and a grinding block 302. An annular baffle 304 is fixedly provided at the center of the outer circumference of the collecting cylinder 301. The grinding blocks 302 are provided in several groups. Several of the grinding blocks 302 are fixedly provided on the circumferential side walls of the collecting cylinder 301 on both sides of the annular baffle 304. Several of the grinding blocks 302 are distributed in an annular manner on the circumferential side walls of the collecting cylinder 301.

[0046] After the hydraulic cylinder liner to be polished is positioned by the positioning assembly 20, the collecting cylinder 301 is driven to rotate inside the hydraulic cylinder liner to be polished by the first driving assembly 40, and at the same time, the collecting cylinder 301 is driven to move back and forth inside the hydraulic cylinder liner to be polished along the length direction of the hydraulic cylinder liner by the second driving assembly 50. When the collecting cylinder 301 rotates and moves, it drives the multiple grinding blocks 302 to rotate and move synchronously. When the multiple grinding blocks 302 rotate and move, they act on the inner wall of the hydraulic cylinder liner to be polished, and then polish the inner wall of the hydraulic cylinder liner to be polished; when the collecting cylinder 301 moves to the right along the inside of the hydraulic cylinder liner to be polished, the air in the right area inside the hydraulic cylinder liner is pressurized and enters between the multiple grinding blocks 302 on the right side of the annular baffle 304, and then is blocked by the annular baffle 304, and then is passed through the multiple air inlet holes 305 and The corresponding several air inlet pipes 306 enter the interior of the collection barrel 301 and are finally discharged to the left area inside the hydraulic cylinder liner through the air outlet pipe 307 on the left wall of the collection barrel 301.

When the air enters the collection barrel 301, it will be simultaneously brought into the collection barrel 301 by the debris polished by the several polishing blocks 302 on the right side of the annular baffle 304. When the debris enters the collection barrel 301, as the air is discharged from the air outlet pipe 307 on the left side, the debris can be blocked by the interception net 308 on the left wall inside the collection barrel 301, thereby collecting the debris inside the collection barrel 301;When the collecting barrel 301 moves to the left along the inside of the hydraulic cylinder liner to be polished, the air in the left area inside the hydraulic cylinder liner is pressurized and enters between the several polishing blocks 302 on the left side of the annular baffle 304, and is then blocked by the annular baffle 304, and then enters the inside of the collecting barrel 301 through the several air inlet holes 305 between the several polishing blocks 302 on the left side and the corresponding several air inlet pipes 306, and finally is discharged to the right area inside the hydraulic cylinder liner through the air outlet pipe 307 on the right side wall of the collecting barrel 301. In this process, the one-way valve inside the several air inlet pipes 306 on the left side of the annular baffle 304 and the collecting barrel 301 are The one-way valve in the air outlet pipe 307 on the right wall of the collection barrel 301 is opened, while the one-way valves in the several air inlet pipes 306 located to the right of the annular baffle 304 and the one-way valve in the air outlet pipe 307 on the left wall of the collection barrel 301 are closed. When air enters the collection barrel 301, it simultaneously carries the debris polished by the several polishing blocks 302 on the left side of the annular baffle 304 into the collection barrel 301. Once the debris enters the collection barrel 301, it is discharged from the air outlet pipe 307 on the right side and is intercepted by the interception net 308 on the right wall of the collection barrel 301, thereby being collected inside the collection barrel 301.

The movable top support plate 202 is arranged on one side of the fixed top support plate 101 and slides with the base plate 10. One end of the adjusting screw 201 is rotatably engaged with the fixed top support plate 101, and the other end passes through the movable top support plate 202 and is threadedly engaged with the movable top support plate 202.

[0048] By placing the hydraulic cylinder liner to be polished between the fixed top support plate 101 and the movable top support plate 202, and then rotating the adjusting screw 201, the movable top support plate 202 is driven close to the fixed top support plate 101 through the threaded cooperation of the adjusting screw 201 and the movable top support plate 202.

[0054] Initially, the collecting barrel 301 is located between the fixed top support plate 101 and the movable top support plate 202, and the collecting barrel 301 is attached to the side wall of the fixed top support plate 101. After the hydraulic cylinder sleeve to be polished is placed on the upper part of the supporting base 103, the staff rotates the adjusting screw 201, thereby driving the movable top support plate 202 to move toward the fixed top support plate 101. The movable top support plate 202 pushes the hydraulic cylinder sleeve so that the hydraulic cylinder sleeve is synchronously close to the fixed top support plate 101. At this time, the collecting barrel 301 enters the liquid Inside the hydraulic cylinder liner, when the hydraulic cylinder liner is supported to the side wall of the fixed support plate 101, the rotating shaft 404 is driven to rotate by the first motor 401, and then the first pulley 403 is driven to rotate. When the first pulley 403 rotates, the support shaft 303 is driven to rotate through the transmission action of the transmission belt 402 and the second pulley 406, thereby driving the collection barrel 301 and several grinding blocks 302 to rotate. When the several grinding blocks 302 rotate, they act on the inner wall of the hydraulic cylinder liner to grind the inner wall of the hydraulic cylinder liner.

When the slide rod 504 moves back and forth, it drives the support shaft 303, the collecting barrel 301, the slide seat 405 and the first motor 401 to move back and forth synchronously, so that the collecting barrel 301 moves back and forth along the inside of the hydraulic cylinder sleeve along the length direction of the hydraulic cylinder sleeve, and cooperates with the rotation of the collecting barrel 301, so that several grinding blocks 302 grind the inner wall of the hydraulic cylinder sleeve.

[0061] The working principle of the present invention is as follows:

[0062] By placing the hydraulic cylinder sleeve to be polished on the upper part of the supporting base 103, the staff then rotates the adjusting screw 201, and the threaded cooperation between the adjusting screw 201 and the movable top support plate 202 drives the movable top support plate 202 to approach the fixed top support plate 101. The movable top support plate 202 pushes one end of the hydraulic cylinder sleeve to make the hydraulic cylinder sleeve move toward the fixed top support plate 101. During this process, the collecting barrel 301 and several polishing blocks 302 synchronously enter the hydraulic cylinder sleeve. When the hydraulic cylinder sleeve is supported to the side wall of the fixed top support plate 101, the first motor 401 and the second motor 501 are started. The first motor 401 drives the rotating shaft 404 to rotate, and then drives the support shaft 303 to rotate through the first pulley 403, the transmission belt 402 and the second pulley 406. The support shaft 303 drives the collecting barrel 301 to rotate, and the second motor 501 drives the turntable 502 to rotate. , thereby driving the shift rod 503 to move in a circle, and the shift rod 503 pushes the sliding rod 504 to move back and forth, thereby driving the sliding seat 405, the first motor 401, the rotating shaft 404, the first pulley 403, the transmission belt 402, the second pulley 406, the support shaft 303 and the collecting cylinder 301 to move back and forth as a whole. When the collecting cylinder 301 rotates and moves back and forth, it drives the several grinding blocks 302 to rotate and move back and forth synchronously, thereby comprehensively grinding the inner wall of the hydraulic cylinder sleeve, and when the collecting cylinder 301 moves back and forth along the inside of the hydraulic cylinder sleeve, the air inside the hydraulic cylinder sleeve is pressurized by the collecting cylinder 301 and flows. The flowing air passes through the inside of the collecting cylinder 301, and then brings the debris generated during the grinding process into the inside of the collecting cylinder 301, thereby collecting the grinding debris and preventing the grinding debris from adhering to the inner wall of the hydraulic cylinder sleeve and affecting the grinding effect of the inner wall of the hydraulic cylinder sleeve.

[0063] In the embodiment of the present invention, when it is necessary to grind the inner wall of the hydraulic cylinder liner, the hydraulic cylinder liner to be grinded can be placed above the bottom plate 10, and then the hydraulic cylinder liner to be grinded is positioned by the positioning assembly 20, and then the collecting grinding assembly 30 is driven by the first driving assembly 40 to rotate inside the hydraulic cylinder liner to be grinded, and the collecting grinding assembly 50 is driven by the second driving assembly 50 to move back and forth along the length direction of the hydraulic cylinder liner inside the hydraulic cylinder liner to be grinded. 30 The inner wall of the hydraulic cylinder liner to be polished is polished during rotation and reciprocating movement, and the debris generated during polishing is collected to prevent the debris from adhering to the inner wall of the hydraulic cylinder liner to be polished, thereby preventing the debris from affecting the polishing effect. Compared with the existing technology, the automatic polishing of the inner wall of the hydraulic cylinder liner can be realized, and the debris generated during the polishing process can be collected to prevent the debris from adhering to the inner wall of the hydraulic cylinder liner, thereby affecting the polishing effect of the inner wall of the hydraulic cylinder liner, and having the advantage of good polishing effect.
