Technical Field
[0001] This utility model belongs to the field of metal product polishing technology, and in particular relates to a metal product inner wall polishing machine. Background Technology
[0002] Metal products are made by modifying the shape and properties of metal materials according to specifications using appropriate mechanical equipment. There are many types of metal products. This utility model mainly targets a cylindrical metal product that requires polishing equipment to polish its inner wall in order to reduce the roughness of the inner wall of the cylinder and remove attached impurities.
[0003] However, when it comes to processing and polishing metal tubes of different specifications, existing polishing mechanisms cannot effectively fix the metal tubes in the center of the fixture, which may result in uneven polishing effects and affect the surface quality of the products. Utility Model Content
[0004] The purpose of this utility model is to provide a metal product inner wall polishing machine. By setting a clamping mechanism, it can ensure that the metal tube can be positioned at the center of the fixed disc, preventing skewing and loosening during polishing, thereby improving the accuracy of polishing. This solves the problem that some polishing mechanisms cannot effectively fix the metal tube at the center of the clamp, which may lead to uneven polishing effect.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a metal product inner wall polishing machine, including a base plate and a metal tube, wherein a clamping mechanism and a polishing mechanism are provided on the base plate;
[0007] The clamping mechanism includes a vertical plate fixedly connected to the top surface of the base plate. A motor is fixedly connected to the inner wall of the vertical plate. The output end of the motor is fixedly connected to a rotating shaft via a coupling. A gear is fixedly connected to the outer wall of the rotating shaft. Four support frames are fixedly connected to the bottom surface of the base plate. A fixed disc is fixedly connected to the top of the four support frames. A connecting disc is rotatably connected to the inner wall of the fixed disc. An external gear ring is fixedly connected to the outer wall of the connecting disc. The external gear ring meshes with the gear. Several arc-shaped grooves are formed on the connecting disc. Sliding rods are slidably connected to the inner walls of the arc-shaped grooves. Two sliders are fixedly connected to the outer walls of the sliding rods. Several grooves are formed on the fixed disc. Several sliders are slidably connected to the inner walls of the grooves.
[0008] Furthermore, a C-shaped rod is fixedly connected to the outer wall of each of the sliding rods, and a positioning roller is rotatably connected to the inner wall of each of the C-shaped rods.
[0009] Furthermore, a metal tube is provided inside the fixed disc, and several positioning rollers are in contact with the outer wall of the metal tube.
[0010] Furthermore, the polishing mechanism includes a hydraulic cylinder fixedly connected to the top surface of the base plate, and a movable stage is fixedly connected to the output end of the hydraulic cylinder.
[0011] Furthermore, two slide rails are fixedly connected to the top surface of the base plate, and the moving platform is slidably sleeved on the outer wall of the two slide rails.
[0012] Furthermore, a fixing ring is fixedly connected to the left side of the mobile platform, and a motor is fixedly connected to the inner wall of the fixing ring.
[0013] Furthermore, the output end of the second motor is fixedly connected to the second rotating shaft via a coupling, and the right end of the second rotating shaft is fixedly connected to polishing cotton, which is in contact with the inner wall of the metal tube.
[0014] This utility model has the following beneficial effects:
[0015] 1. By incorporating a clamping mechanism, when the motor on the drive plate drives the rotating shaft to rotate, it will cause the rotating shaft and gear to rotate synchronously. Multiple support frames support the fixed disc, allowing the connecting disc to rotate on the inner wall of the fixed disc as the gear drives the support frames to rotate. The slider and the slide groove cooperate with each other, allowing the slider to slide up and down only on the inner wall of the slide groove. At the same time, the slide rod and the arc-shaped slide groove cooperate with each other, allowing multiple positioning rollers to move synchronously towards the center of the connecting disc when the connecting disc rotates. This enables the multiple positioning rollers to fix the outer wall of the metal tube. This mechanism can greatly improve the stability of the fixation and ensure that the metal tube can be positioned in the center of the fixed disc, preventing skewing and loosening during grinding, making the polishing more uniform, and thus improving the precision of grinding and polishing.
[0016] 2. By setting up a polishing mechanism, after the second drive motor drives the second rotating shaft and the polishing cotton to rotate, it can drive the hydraulic cylinder to move the moving table to the right. The second rotating shaft is concentric with the fixed disc, which allows the rotating polishing cotton to quickly polish the inner wall of the metal tube, greatly improving the efficiency and convenience of polishing.

[0027] Please see Figure 1-5 As shown, this utility model is a metal product inner wall polishing machine, including a base plate 1 and a metal tube 4. The base plate 1 is provided with a clamping mechanism 2 and a polishing mechanism 3.
[0028] The clamping mechanism 2 includes a vertical plate 21 fixedly connected to the top surface of the base plate 1. A motor 22 is fixedly connected to the inner wall of the vertical plate 21.

A connecting disc 27 is rotatably connected to the inner wall of the fixed disc 26. An external gear ring 28 is fixedly connected to the outer wall of the connecting disc 27. The external gear ring 28 meshes with the gear 24. Several arc-shaped sliding grooves 29 are provided on the connecting disc 27. Sliding rods 291 are slidably connected to the inner walls of the several arc-shaped sliding grooves 29. Two sliding rods 291 are fixedly connected to the outer walls of the several sliding rods 291. The slider 292 has several grooves 295 on the fixed disc 26. Several sliders 292 are slidably connected to the inner walls of the grooves 295. The outer walls of several sliding rods 291 are fixedly connected to C-shaped rods 293. The inner walls of several C-shaped rods 293 are rotatably connected to positioning rollers 294. The fixed disc 26 has a metal tube 4 inside. Several positioning rollers 294 are in contact with the outer walls of the metal tube 4.

[0029] The polishing mechanism 3 includes a hydraulic cylinder 31 fixedly connected to the top surface of the base plate 1. A movable stage 32 is fixedly connected to the output end of the hydraulic cylinder 31. Two slide rails 33 are fixedly connected to the top surface of the base plate 1. The movable stage 32 is slidably sleeved on the outer wall of the two slide rails 33. A fixing ring 34 is fixedly connected to the left side of the movable stage 32.
