Description

Technical Field

[0001] This utility model relates to the field of ring shot blasting technology, specifically a double-sided ring shot blasting machine. Background Technology

[0002] A ring polisher, also known as a continuous ring polishing machine, is a device designed based on the continuous ring polishing method. Its core function is to achieve controllable operating factors to obtain high-precision components. The ring polisher uses an electric motor to drive a sponge or wool polishing disc mounted on the machine to rotate at high speed. The polishing disc and polishing agent work together to rub against the surface to be polished, thereby removing surface contaminants, oxide layers, and shallow scratches.

[0003] Currently, in most existing double-sided ring polishing machines, due to the linear velocity of rotation, the edge speed of the turntable often far exceeds the material's tolerance when processing large surfaces, easily leading to edge collapse. Therefore, we propose a new double-sided ring polishing machine. Utility Model Content

[0004] The main objective of this invention is to provide a double-sided ring shot blaster that can solve the problems mentioned in the above-mentioned technical background.

[0005] To achieve the above objectives, this utility model proposes a double-sided ring polishing machine, comprising a main body, wherein the main body is equipped with a grinding device, the grinding device comprising:

[0006] The main grinding disc has a clearance groove on its bottom surface. A small grinding disc is rotatably connected to the inner wall of the main grinding disc. A transmission gear is fixedly connected to the upper surface of the small grinding disc. The surface of the transmission gear meshes with the surface of the rack. A limit block is fixedly connected to the upper surface of the rack. The inner wall of the rack is slidably connected to the surface of the limit strip. The surface of the limit strip is fixedly connected to the upper surface of the main grinding disc.

[0007] Preferably, the surface of the limiting block is slidably connected to the inner wall of the inclined groove, and the inclined groove is opened on the surface of the main turntable.

[0008] Preferably, the upper surface of the main turntable is rotatably connected to one end of the drive rod, and the other end of the drive rod is rotatably connected to the upper surface of the small turntable.

[0009] Preferably, the bottom surface of the small turntable is fixedly connected to the output end of the drive motor, and the surface of the drive motor is fixedly connected to the upper surface of the main grinding disc.

[0010] Preferably, the main body of the device includes a bracket, a screw motor is fixedly connected to the inner wall of the bracket, the output end of the screw motor passes through the bracket and is fixedly connected to one end of a threaded rod, the other end of the threaded rod is rotatably connected to the inner wall of the bracket, and a movable rod is threadedly connected to the surface of the threaded rod.

[0011] Preferably, a grinding disc motor is fixedly connected to the surface of both the moving rod and the support, and the output end of the grinding disc motor is fixedly connected to the surface of the main grinding disc.

[0012] Beneficial effects

[0013] This utility model provides a double-sided ring polishing machine. It has the following beneficial effects:

[0014] This double-sided ring polishing machine, through its set grinding device, applies polishing cloth to the surfaces of the main grinding disc and the small grinding disc when grinding the valve core is required. The screw motor drives the threaded rod to rotate, causing the moving rod to move the grinding device to the appropriate position, tightly against the fixed valve core. The grinding disc motor and drive motor are then activated, causing the grinding disc motor to rotate the main turntable for polishing, while the drive motor drives the small turntable to rotate. This causes the drive rod to drive the main turntable to reciprocate, thus pushing the rack to slide back and forth on the surface of the limiting strip through the inclined groove. This, in turn, drives the transmission gear and the small grinding disc to rotate independently. This ensures that when polishing large surfaces, each area of ​​the large surface is individually ground by the small grinding disc, thereby reducing the grinding speed of the same main grinding disc and preventing edge collapse.

[0023] Please see Figures 1-4 This utility model proposes a double-sided ring polishing machine, including a device body 1. The device body 1 includes a support 101. A screw motor 102 is fixedly connected to the inner wall of the support 101. The output end of the screw motor 102 passes through the support 101 and is fixedly connected to one end of a threaded rod 103. The other end of the threaded rod 103 is rotatably connected to the inner wall of the support 101. A moving rod 104 is threadedly connected to the surface of the threaded rod 103. A grinding disc motor 105 is fixedly connected to both the moving rod 104 and the surface of the support 101. The output end of the grinding disc motor 105 is fixedly connected to the surface of the main grinding disc 201.

[0024] The main body 1 is equipped with a grinding device 2, which includes a main grinding disc 201. A clearance groove 202 is formed on the bottom surface of the main grinding disc 201. A small grinding disc 203 is rotatably connected to the inner wall of the main grinding disc 201. A transmission gear 204 is fixedly connected to the upper surface of the small grinding disc 203. The surface of the transmission gear 204 meshes with the surface of a rack 205. A limit block 206 is fixedly connected to the upper surface of the rack 205. The inner wall of the rack 205 slides against the surface of the limit block 207. The connection is as follows: the surface of the limiting strip 207 is fixedly connected to the upper surface of the main grinding disc 201; the surface of the limiting block 206 is slidably connected to the inner wall of the inclined groove 208; the inclined groove 208 is formed on the surface of the main turntable 209; the upper surface of the main turntable 209 is rotatably connected to one end of the drive rod 210; the other end of the drive rod 210 is rotatably connected to the upper surface of the small turntable 211; the bottom surface of the small turntable 211 is fixedly connected to the output end of the drive motor 212; the drive motor 212... The surface is fixedly connected to the upper surface of the main grinding disc 201. When the valve core needs to be polished, polishing cloth is attached to the surfaces of the main grinding disc 201 and the small grinding disc 203 through the setting polishing device 2. The screw motor 102 drives the threaded rod 103 to rotate, so that the moving rod 104 drives the polishing device 2 to move to the appropriate position and tightly adhere to the fixed valve core. The grinding disc motor 105 and the drive motor 212 are started, so that the grinding disc motor 105 drives the main grinding disc 201 to rotate for polishing, while the drive motor 212 drives the small turntable 211 to rotate, so that the drive rod 210 drives the main grinding disc 201 to reciprocate. This pushes the rack 205 to reciprocate on the surface of the limit strip 207 through the inclined groove 208, thereby driving the transmission gear 204 and the small grinding disc 203 to rotate individually. This ensures that when polishing a large surface, each part of the large surface is polished by the small grinding disc 203 individually, avoiding the problem of edge collapse.

[0025] In this invention, when the valve core needs to be polished, polishing cloth is attached to the surfaces of the main grinding disc 201 and the small grinding disc 203. The screw motor 102 is controlled to drive the threaded rod 103 to rotate, so that the moving rod 104 drives the polishing device 2 to move to the appropriate position and fit tightly against the fixed valve core. The grinding disc motor 105 and the drive motor 212 are started, so that the grinding disc motor 105 drives the main grinding disc 201 to rotate and polish, while the drive motor 212 drives the small turntable 211 to rotate, so that the drive rod 210 drives the main grinding disc 201 to reciprocate. This pushes the rack 205 to reciprocate on the surface of the limiting strip 207 through the inclined groove 208, thereby driving the transmission gear 204 and the small grinding disc 203 to rotate independently.
