Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic cylinder processing technology, specifically a polishing device for hydraulic cylinder processing. Background Technology
[0002] A hydraulic cylinder, also known as a hydraulic cylinder, is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. During the production of hydraulic cylinders, a polishing device is used to grind and polish the cylinder shell. For example, patent application number 201822119362.9, entitled "A Polishing Device for Vacuum Hydraulic Cylinder Processing," relates to the field of vacuum hydraulic cylinder processing technology. This polishing device includes a hydraulic cylinder, a polishing apparatus, a motor, and a drive box. A support plate is fixedly connected to one end of the polishing apparatus, and springs are symmetrically fixedly connected to one side of the support plate. One end of each spring is fixedly connected to a support plate. Pins are movably installed at both the upper and lower ends of the support plate. Each of the two pins is movably connected to a connecting rod. One end of each connecting rod passes through the upper and lower sides of the polishing device and is fixedly connected to a polishing pad. In this polishing device for vacuum cylinder processing, the connecting rods retract inward when the locking rod is pushed forward, making it easier for the polishing device to be inserted into the cylinder. After the polishing device enters the cylinder, the locking rod is pulled back to the bottom, so that the two connecting rods are vertically aligned. Then, the positions of the two connecting rods are fixed by the cooperation between the locking rod and the stop groove.
[0003] The aforementioned technologies have the following drawbacks: when polishing the inside of the cylinder housing, a clamp is used to hold and fix the cylinder housing. However, when workers use the clamp to hold the cylinder housing, they are prone to making mistakes, resulting in excessive clamping force, which can damage the cylinder housing. In severe cases, it can cause the cylinder housing to deform, thus reducing the practicality of the polishing device.
[0004] Therefore, the polishing device needs to be redesigned and modified to effectively prevent its practicality issues. Utility Model Content

A ring frame 7 is fixedly connected to the top of the movable plate 6. A sealing rubber 8 is fixedly connected to the inner side of the ring frame 7. Ventilation holes 9 are provided on the surface of the sealing rubber 8 and the inner side of the ring frame 7. An air distribution manifold 10 is fixedly connected to the top of the ring frame 7. The air inlet of the air distribution manifold 10 extends into the interior of the ring frame 7. An air pump 11 is connected to the right side of the air distribution manifold 10. An auxiliary mechanism is provided at the bottom of the movable plate 6, and a support mechanism is provided on the right side of the support plate 2.
[0026] refer to Figure 5 The auxiliary mechanism includes a mounting bracket 12 fixedly connected to the bottom of the movable plate 6 and located on the front and back of the electric guide rail 5 respectively. A rubber wheel 13 is movably connected inside the mounting bracket 12. The bottom of the rubber wheel 13 extends to the outside of the mounting bracket 12 and is movably connected to the top of the fixed plate 1.
[0027] As a technical optimization of this utility model, the movable plate 6 is supported by the mounting frame 12 and the rubber wheel 13 to prevent the movable plate 6 from tilting, and the rolling friction of the rubber wheel 13 prevents the movable plate 6 from rubbing against the fixed plate 1.
[0028] refer to Figure 3 The support mechanism includes an auxiliary tube 14 movably connected to the surface of the output end of the motor 3. A reinforcing rod 15 is fixedly connected to the surface of the auxiliary tube 14. The left side of the reinforcing rod 15 is fixedly connected to the right side of the support plate 2. A lubrication mechanism is provided inside the auxiliary tube 14.
[0029] As a technical optimization of this utility model, by setting an auxiliary tube 14 and a reinforcing rod 15, the output end of the motor 3 is supported, so as to prevent the output end of the motor 3 from bending downward due to gravity, which would affect the polishing effect of the polishing device on the cylinder shell.
[0030] refer to Figure 3 The lubrication mechanism includes a fixed groove 16 formed in the inner wall of the auxiliary pipe 14. A solid lubricant 17 is fixedly connected inside the fixed groove 16. The inner side of the solid lubricant 17 extends to the outside of the fixed groove 16 and is movably connected to the surface of the output end of the motor 3.
[0031] As a technical optimization of this utility model, by setting a fixing groove 16 and a solid lubricant 17, when the solid lubricant 17 rubs against the output end of the motor 3, the lubricant in the solid lubricant 17 will be transferred to the output end of the motor 3, lubricating the output end of the motor 3 and the auxiliary pipe 14, thereby reducing the wear on the auxiliary pipe 14 and the output end of the motor 3.
[0032] refer to Figure 2The support plate 2 has reinforcing ribs 18 fixedly connected to both sides. The reinforcing ribs 18 are located on the front and back of the motor 3, respectively, and the bottom of the reinforcing ribs 18 is fixedly connected to the top of the fixing plate 1.
[0033] As a technical optimization of this utility model, the support plate 2 is reinforced by setting the reinforcing rib 18, which improves the firmness of the connection between the support plate 2 and the fixed plate 1 and prevents the support plate 2 from breaking due to external impact.
[0034] refer to Figure 4 A shock absorber 19 is fixedly connected to the bottom of the fixed plate 1, and a wear-resistant base plate 20 is fixedly connected to the bottom of the shock absorber 19.
[0035] As a technical optimization of this utility model, by setting a shock absorber 19 and a wear-resistant base plate 20, the vibration generated during the operation of the polishing device is absorbed, and the polishing device is prevented from shifting due to vibration.
[0036] The working principle and usage process of this utility model are as follows: When in use, first place the cylinder shell into the ring frame 7, so that the sealing rubber 8 seals with the surface of the cylinder shell. Then, start the vacuum pump 11. The vacuum pump 11 extracts the air from the ring frame 7 through the air distributor 10, so that the ring frame 7 is in a negative pressure state. The ring frame 7 is adsorbed and fixed to the surface of the cylinder shell through the ventilation hole 9 and the sealing rubber 8. Then, start the electric guide rail 5. The electric guide rail 5 drives the moving plate 6, the ring frame 7 and the cylinder shell to move to the left through the sliding block, so that the polishing wheel 4 is inserted into the inside of the cylinder shell. At the same time, start the motor 3. The motor 3 drives the polishing wheel 4 to rotate through the output end. The polishing wheel 4 polishes the inner wall of the cylinder shell by rotating.
[0037] In summary, this polishing device for hydraulic cylinder processing seals the annular frame 7 and the cylinder shell with a sealing rubber 8, and uses an air pump 11 and an air distributor 10 to extract air from the annular frame 7, creating a negative pressure state inside the annular frame 7. The annular frame 7 uses this negative pressure to adhere and fix the surface of the cylinder shell through the ventilation holes 9. Because the cylinder shell is fixed by adsorbing it with negative pressure, it avoids damage to the cylinder shell due to mistakes, thus improving the practicality of the polishing device.
