A metal surface polishing machine

Abstract

This utility model relates to the technical field of sheet metal processing equipment, specifically a metal surface polishing machine, including a frame and a support assembly. The support assembly includes a lower crossbeam and an upper crossbeam. The left ends of both the lower and upper crossbeams are fixedly connected to the left side of the frame. A drive roller is rotatably connected to the lower crossbeam. Multiple vertically sliding support columns are inserted into the upper crossbeam. A U-shaped seat is fixedly connected to the top of each support column, and a driven roller is rotatably connected inside the U-shaped seat. The advantage is that the strong vibration generated by the driven roller during high-speed operation is transmitted laterally to the support columns, which are then supported by the upper crossbeam, thus overcoming the lateral vibration. Therefore, the piston rod end of the cylinder only needs to bear the weight of the driven roller and the vertical vibration force, preventing the piston rod end from bending and being damaged due to stress, thereby extending the cylinder's service life.

Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment, and in particular to a metal surface polishing machine. Background Technology

[0002] Polishing machines remove the oxide layer from metal surfaces through grinding, thus achieving the purpose of polishing. A common polishing machine structure mainly consists of a motor, transmission mechanism, abrasive belt, drive roller, and driven roller. The drive roller is located below the driven roller, and the abrasive belt is fitted onto the drive roller and driven roller. The motor drives the lower drive roller to rotate through the pulley and belt of the transmission mechanism, thereby driving the abrasive belt and driven roller to rotate, conveying the metal sheet to be polished from below the abrasive belt, thus achieving the purpose of grinding and polishing the surface of the metal sheet.

[0003] Sanding belts are consumable parts. To facilitate belt replacement, a cylinder for raising and lowering the driven roller is installed under its support. When replacing the sanding belt, the cylinder is retracted, causing the driven roller to descend, thereby shortening the distance between the upper and lower roller shafts, making it easy to remove the sanding belt for replacement. However, existing polishing machines still have the following drawbacks in use:

[0004] The driven roller's support is mainly supported by a cylinder. Therefore, during the polishing process, the high-speed rotation of the sand belt generates a strong vibration, causing the driven roller's support to sway from side to side. The cylinder's piston rod will be subjected to a strong lateral force, which makes the cylinder's piston rod prone to deformation and twisting, ultimately leading to cylinder damage. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0006] Therefore, one objective of this utility model is to provide a metal surface polishing machine that aims to solve the problem of easy damage to the cylinder used to support the driven roller in existing polishing machines.

[0007] To achieve the above objectives, one embodiment of this utility model provides a metal surface polishing machine, including a frame and a support assembly. The support assembly includes a lower crossbeam and an upper crossbeam. The left ends of both the lower and upper crossbeams are fixedly connected to the left side of the frame. A drive roller is rotatably connected to the lower crossbeam. Multiple sliding support columns are inserted into the upper crossbeam. A U-shaped seat is fixedly connected to the top of each support column. A driven roller is rotatably connected to the inside of the U-shaped seat. A top beam is fixedly connected to the bottom of the multiple support columns. A cylinder is installed between the lower crossbeam and the top beam. A sanding belt is fitted onto the surfaces of the drive roller and the driven roller.

[0008] The beneficial effects are as follows: the strong vibration generated by the driven roller during high-speed operation, in which the lateral vibration force is transmitted to the support column, the support column is supported by the upper crossbeam, thereby overcoming the lateral vibration force. Therefore, the piston rod end of the cylinder only needs to bear the weight of the driven roller and the vertical vibration force, so the piston rod end of the cylinder will not be bent or damaged due to the force, thus improving the service life of the cylinder.

[0009] In a preferred embodiment, a bearing housing 1 is installed on the left side of the frame, a bearing housing 2 is installed at the bottom of the right end of the lower crossbeam, and the two ends of the drive roller are respectively installed in bearing housing 1 and bearing housing 2.

[0010] The beneficial effect is that there is no obstruction structure on the right end of the driving roller and the driven roller, which makes it easier to replace the sanding belt.

[0011] In a preferred embodiment, a motor is fixedly installed at the bottom of the frame, and pulleys are keyed to the output shaft end of the motor and the left end of the drive roller. The two pulleys are connected by belt drive. A lifting assembly is installed inside the frame, and a conveyor belt is installed at the top of the lifting part of the lifting assembly. The lifting assembly can lift the conveyor belt, thereby adjusting the distance between the conveyor belt and the sanding belt, making it suitable for polishing metal sheets of different thicknesses.

[0012] A preferred embodiment further includes a detachable reinforcement component for supporting the right end of the lower crossbeam.

[0013] Furthermore, the reinforcing component includes a threaded cylinder with a screw threadedly connected to its interior. A limit block is fixedly connected to the top end of the screw. A top block is welded and fixed to the right end of the lower crossbeam, and the reinforcing component is installed below the top block.

[0014] Furthermore, a notch is provided on one side of the top block, and an extension rod is welded and fixed to the top of the limiting block. The extension rod is inserted into the notch, and a connector is welded and fixed to the top of the extension rod.

[0015] Furthermore, a support rod is fixedly connected between the top of the right end of the lower crossbeam and the bottom of the right end of the upper crossbeam.

[0016] The beneficial effects are as follows: by supporting the right end of the lower crossbeam, the reinforcement component can improve the stability of the lower crossbeam and prevent the right end of the lower crossbeam from sagging due to gravity and the welded part of the left end to the frame from breaking. The setting of the support rod allows the upper crossbeam to be reinforced at the same time as the lower crossbeam.

[0017] In a preferred embodiment, a support rod is hinged to the bottom of the left end of the upper crossbeam, and a slot is provided in the middle of the support rod. The slot fits onto the outer surface of the cylinder, and a hole is provided on the side of the support rod. A top rod is welded and fixed to the top of the connector.

[0018] The beneficial effects are as follows: the top rod supports the right end of the support rod, which in turn supports the top beam, thereby supporting the driven roller. Therefore, it can share the vertical force on the cylinder, further protecting the cylinder. Moreover, the design of the support rod will not affect the replacement efficiency of the sanding belt.

[0030] This invention provides a metal surface polishing machine.

[0031] Example 1:

[0032] like Figure 1 As shown, it includes a frame 1, a support assembly 2, and a reinforcement assembly 6.

[0033] like Figure 2-3 As shown, the support assembly 2 includes a lower crossbeam 21 and an upper crossbeam 22. The left ends of both the lower crossbeam 21 and the upper crossbeam 22 are welded and fixed to the left side of the frame 1. A bearing seat 11 is installed on the left side of the frame 1. A bearing seat 23 is installed at the bottom of the right end of the lower crossbeam 21. The two ends of the drive roller 30 are respectively installed in the bearing seat 11 and the bearing seat 23. The upper crossbeam 22 has multiple insertion holes that extend from its top to its bottom. Support columns 24 are inserted into each of the multiple insertion holes. A U-shaped seat 25 is welded and fixed to the top of the support column 24. A driven roller 31 is rotatably connected inside the U-shaped seat 25. A top beam 26 is welded and fixed to the bottom of the support column 24. A cylinder 27 is installed between the lower crossbeam 21 and the top beam 26. By extending the cylinder 27, the top beam 26 can be driven to rise and fall, thereby achieving the purpose of raising and lowering the driven roller 31. A sanding belt 32 is sleeved on the surface of the drive roller 30 and the driven roller 31.

[0034] like Figure 2 As shown, a motor 12 is fixedly installed at the bottom of the frame 1. The output shaft end of the motor 12 and the left end of the drive roller 30 are both keyed to pulleys 13, and the two pulleys 13 are connected by a belt 14, so that the motor 12 can drive the drive roller 30 to rotate the sanding belt 32.

[0035] like Figure 1-2As shown, a lifting assembly 4 is installed inside the frame 1. The lifting assembly 4 includes four worm gear lifters and a drive motor. The four worm gear lifters are interconnected through a transmission shaft, a synchronous pulley, and a synchronous belt. The drive motor drives the worm end of one of the worm gear lifters, which in turn causes the lifting screws of the four worm gear lifters to move up and down. The specific connection method of the lifting assembly 4 is prior art and will not be described in detail in this application. The top ends of the lifting screws of the four worm gear lifters are connected to a conveyor belt 5, which is located below the sanding belt 32. The lifting assembly 4 can move the conveyor belt 5 up and down, thereby enabling the polishing of metal plates of different thicknesses.

[0036] like Figure 1 , Figure 3 and Figure 4 As shown, the reinforcing component 6 includes a threaded cylinder 61, with a screw 62 threadedly connected to its interior. A limit block 63 is welded and fixed to the top of the screw 62. A top block 64 is welded and fixed to the right end of the lower crossbeam 21. Rotating the screw 62 causes it to extend out of the threaded cylinder 61. The bottom of the threaded cylinder 61 is supported within the frame 1. The limit block 63 rests against the bottom of the top block 64, thus supporting the lower crossbeam 21 and reinforcing its stability. A notch 65 is provided on one side of the top block 64. An extension rod 66 is welded and fixed to the top of the position block 63. The extension rod 66 is inserted into the notch 65, and a connector 67 is welded and fixed to the top of the extension rod 66. The screw 62 can be turned by using a wrench on the surface of the connector 67. When reinforcing the lower crossbeam 21, it is convenient to apply force to the screw 62. A support rod 28 is welded and fixed between the top of the right end of the lower crossbeam 21 and the bottom of the right end of the upper crossbeam 22, so that the reinforcement component 6 reinforces the lower crossbeam 21 and the upper crossbeam 22 at the same time.

[0037] The working principle of this embodiment is as follows: When replacing the sanding belt 32, the cylinder 27 retracts, and the support column 24 slides downward in the insertion hole of the upper crossbeam 22, thereby causing the driven roller 31 to descend. The distance between the driving roller 30 and the driven roller 31 decreases, thus loosening the sanding belt 32. At this time, by twisting the screw 62 on the surface of the connector 67 with a wrench, the screw 62 is retracted into the threaded cylinder 61, and the reinforcing component 6 can be removed. The right side of the sanding belt 32 will then be free of obstruction, allowing the sanding belt 32 to be easily pulled out. Then, the new sanding belt can be removed. The sanding belt 32 is fitted onto the driving roller 30 and the driven roller 31. The reinforcing component 6 is installed, and then the cylinder 27 is extended to raise the driven roller 31, thereby tightening the sanding belt 32 and completing the replacement of the sanding belt 32. During the high-speed rotation of the sanding belt 32 driven by the motor 12, the lateral force generated by the vibration of the driven roller 31 is transmitted to the support column 24. The support column 24 is supported by the upper crossbeam 22, so that too much force is transmitted to the piston rod end of the cylinder 27, thus avoiding the problem of the piston rod end of the cylinder 27 bending and being damaged by force.

[0038] Example 2:

[0039] like Figure 5-6 As shown, based on Embodiment 1, a support rod 7 is hinged to the bottom of the left end of the upper crossbeam 22, and a slot 71 is opened in the middle of the support rod 7. The slot 71 is fitted onto the outer surface of the cylinder 27, and a hole 72 is opened on the side of the support rod 28. The right end of the support rod 7 passes through the hole 72 and penetrates the support rod 28. A top rod 73 is welded and fixed to the top of the connector 67. When the reinforcing component 6 supports the top block 64, the top rod 73 supports the bottom of the support rod 7 and supports the right end of the support rod 7. At this time, the support rod 7 supports the bottom of the top beam 26, so it can share the force of the cylinder 27 and further protect the cylinder 27.

[0040] The working principle of this embodiment is as follows: When replacing the sanding belt 32, the reinforcing component 6 is first disassembled. At this time, the right end of the support rod 7 droops down, and the support rod 7 no longer supports the top beam 26. Then the cylinder 27 can be retracted to disassemble and replace the sanding belt 32. After replacing the sanding belt 32, push the right end of the support rod 7 to support the bottom of the top beam 26, and then install the reinforcing component 6.
