Description

Technical Field

[0001] The utility model belongs to the field of metal product production, and in particular relates to a metal product polishing device. Background Art

[0002] The metal products industry includes the manufacturing of structural metal products, metal tool manufacturing, container and metal packaging container manufacturing, stainless steel and similar daily metal products manufacturing, etc. When manufacturing metal products, people usually need to polish the metal products to make their surface smoother.

[0003] At present, people usually use polishing belts to polish metal products. First, the polishing belt is started to rotate, and then people hold the metal product and put it in contact with the polishing belt. Under the action of the polishing belt, the purpose of polishing the metal product can be achieved. However, the polishing belt is prone to loosening after being used for a long time, which affects the polishing effect. When loosening occurs, the distance between the two rotating rods is usually adjusted by turning a screw to tighten the polishing belt. However, the screw is prone to rust after long-term use, making it difficult for people to turn it to adjust the tightness, and the adjustment is inconvenient.

[0004] In summary, there is an urgent need for a metal product polishing device that can conveniently adjust the tightness of the polishing belt to solve the above-mentioned problems. Utility Model Content

A screw is rotatably arranged on the left side of the connecting plate. The screw is threadedly connected to the push-pull shaft. A polishing belt is wound around the roller and the sleeve shaft.

[0008] Furthermore, it also includes a storage frame, a cylindrical valve, a fixed block, a sponge block and a mounting rod. The storage frame is fixedly connected to the top of the working platform, the storage frame is located on the rear side of the fixed plate, a cylindrical valve is slidably arranged at the lower part of the storage frame, and there is a certain gap between the cylindrical valve and the storage frame. Fixed blocks are installed on the outer side of the fixed plate through the mounting rod, and a sponge block is rotatably arranged between the two fixed blocks. The sponge block is in contact with the polishing belt, and a protrusion is arranged on the sponge block.

[0009] Furthermore, a transparent plate is also included, and the front side of the storage frame is connected with the transparent plate.

[0010] Furthermore, the interior of the storage frame is arranged as an inclined surface.

[0011] Furthermore, two groove holes are formed on the gripping rod on the left side of the screw rod.

[0012] Furthermore, rubber bottom plates are arranged on four sides of the bottom of the working platform.

[0013] The beneficial effects are:

[0014] 1. The utility model rotates the screw rod, which drives the push-pull shaft to move rightward, and the push-pull shaft drives the connecting rod piece to rotate rightward, and the connecting rod piece drives the expansion block to move outward, so that the polishing belt can be stretched outward to make it tight, which is convenient for people to polish.

[0015] 2. The rotation of the polishing belt of the utility model will drive the sponge block to rotate, and the rotation of the sponge block will intermittently squeeze the cylindrical valve to move upward, so that the polishing agent in the storage frame will intermittently fall down onto the sponge block, achieving the purpose of intermittent material discharge and making the polishing smoother.

DETAILED DESCRIPTION

[0023] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Embodiment: A metal product polishing device, see Figure 1-Figure 6 As shown, it includes a working platform 1, a fixing plate 2, a servo motor 3, a roller, a connecting plate 4, a sleeve shaft 5, a push-pull shaft 6, a connecting rod sheet 7, a tightening block 8, a screw rod 9, a polishing belt 10, a storage frame 11, a cylinder valve 12, a fixing block 13, a sponge block 14, a mounting rod 15 and a transparent plate 16. The left and right sides of the top of the working platform 1 are connected with the fixing plate 2 by bolts, and the four sides of the bottom of the working platform 1 are provided with rubber bottom plates. The right side of the fixing plate 2 on the right side is installed with a servo motor 3. The servo motor The output shaft of the motor 3 is connected with a roller through a coupling, and the roller is rotatably connected to the fixed plate 2 on the left side. A connecting plate 4 is slidably arranged at the left front of the fixed plate 2 on the left side. A sleeve shaft 5 is rotatably arranged between the front parts of the two fixed plates 2. A push-pull shaft 6 is slidably arranged at the front of the sleeve shaft 5. Four connecting rod pieces 7 are rotatably arranged at intervals on the push-pull shaft 6. A tightening block 8 is rotatably arranged between the two corresponding connecting rod pieces 7 on the left and right. The tightening block 8 is slidably connected to the sleeve shaft 5. The tightening block 8 is a long square The polishing belt 10 is arranged in a block shape, and the expansion block 8 moves outward to stretch the polishing belt 10 outward so that it is in a taut state. A screw rod 9 is rotatably arranged on the left side of the connecting plate 4, and the screw rod 9 is threadedly connected to the push-pull shaft 6. Two groove holes are opened on the grip rod on the left side of the screw rod 9. A polishing belt 10 is wound around the roller and the sleeve shaft 5. A storage frame 11 is fixedly connected to the top of the working platform 1 by bolts. The storage frame 11 is located on the rear side of the fixed plate 2. The interior of the storage frame 11 is arranged as an inclined surface. A cylindrical valve 12 is slidably arranged at the lower part of the storage frame 11. There is a certain gap between the cylindrical valve 12 and the storage frame 11. The intermittent up and down movement of the cylindrical valve 12 can be intermittent unloading. Fixed blocks 13 are installed on the outside of the fixed plate 2 through mounting rods 15. A sponge block 14 is rotatably arranged between the two fixed blocks 13. The sponge block 14 contacts with the polishing belt 10, and a protrusion is arranged on the sponge block 14. The sponge block 14 is used to wipe the polishing agent on the surface of the polishing belt 10. A transparent plate 16 is connected to the front side of the storage frame 11.

[0025] When the device is needed, the device is first placed at a designated position, and then the servo motor 3 is started. The output shaft of the servo motor 3 rotates to drive the roller to rotate, so that the polishing belt 10 rotates through the sleeve shaft 5, the push-pull shaft 6, the connecting plate 4 and the screw rod 9. Then, people can pour a proper amount of polishing agent into the storage frame 11, and the amount of polishing agent used can be viewed through the transparent plate 16. When the polishing belt 10 rotates, the rotation of the polishing belt 10 will drive the sponge block 14 to rotate, and the rotation of the sponge block 14 will intermittently squeeze the cylindrical valve 12 to move upward, so that the polishing agent in the storage frame 11 intermittently falls down onto the sponge block 14, achieving intermittent polishing. The purpose of unloading is to wipe the polishing agent on the polishing belt 10 by rotating the sponge block 14. At this time, people put the metal product in contact with the polishing belt 10, and can grind the metal product by rotating the polishing belt 10. Under the action of the polishing agent, the metal product can be polished more smoothly. After grinding, turn off the motor. When the polishing belt 10 is loose, people can rotate the screw rod 9. The rotation of the screw rod 9 will drive the push-pull shaft 6 to move to the right. The push-pull shaft 6 moves to the right and drives the connecting rod piece 7 to rotate. The rotation of the connecting rod piece 7 drives the expansion block 8 to move outward, so that the polishing belt 10 can be stretched outward to make it tight, which is convenient for people to grind.
