[0002] Polishing machine is also called grinding machine, which is often used for mechanical grinding, polishing and waxing. Its working principle is: the motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at high speed. Due to the joint action of the polishing disc and the polishing agent and the friction with the surface to be polished, the paint surface pollution, oxide layer and shallow marks can be removed. The application range of polishing device is very wide. For example, threaded elements are high-precision metal accessories. Some threaded elements have inner grooves inside, such as threaded sleeves. When polishing the inner groove of the threaded sleeve, a threaded element inner groove polishing device is needed, as shown below.

[0003] After searching, the patent with the authorization publication number CN216325662U discloses a high-precision threaded element inner groove polishing device, including a polishing table, the bottom of the polishing table is fixedly connected to a bottom motor, the bottom motor passes through the output end of the polishing table and is fixedly connected to a rotating support frame, the top of the rotating support frame is fixedly connected to a rotating table, the bottom of the rotating support frame is fixedly connected to a supporting slide, the supporting slide is slidably connected to the polishing table, the top of the rotating table is fixedly connected to a side seat, the side of the side seat is fixedly connected to a fixing spring, and one end of the fixing spring is fixedly connected to a clamping frame. The utility model is convenient for the staff to adjust according to the specific size of the threaded element when using it through the cooperation between the fixing spring, the clamping frame, the sliding seat and the side seat, so as to avoid the threaded elements of different sizes from being easily loosened during clamping, which affects the normal use of the staff.

[0004] However, the above patent still has the following aspects that can be optimized:

[0005] Threaded elements are generally cylindrical. When clamping and fixing the threaded elements, due to the elastic characteristics of the spring, it is difficult to clamp and fix the threaded elements well by using the spring rebound force in conjunction with the clamping frame, resulting in poor stability of the threaded elements. During the processing, the threaded elements are prone to movement and falling off, affecting the processing. Moreover, since the size of the clamping frame is fixed, it is difficult to apply to threaded elements of various sizes. Therefore, its scope of application is small. Therefore, its overall structure needs to be improved and its practicality needs to be improved. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a high-precision threaded element inner groove polishing device, comprising a processing table 1, a rotating seat structure, a clamping and fixing structure, a top plate 2 and a lifting polishing structure, wherein a plurality of supporting legs are provided at the bottom of the processing table 1, an annular slide groove 3 is provided at the upper end surface of the processing table 1, the rotating seat structure is installed at the top and bottom of the processing table 1, the clamping and fixing structure is installed at the rotating seat structure, the top plate 2 is fixedly mounted above the processing table 1 through a plurality of supporting columns 4, the lifting polishing structure is installed at the top plate 2, and the position of the lifting polishing structure matches the positions of the rotating seat structure and the clamping and fixing structure;

[0022] The rotating seat structure includes a motor A5 and a bearing seat 6. The motor A5 is fixedly installed at the bottom of the processing table 1 through a mounting frame. The output end of the motor A5 movably passes through the processing table 1 and extends to the top of the processing table 1. The bottom of the bearing seat 6 is connected to the output end of the motor A5, so that the bearing seat 6 can be driven to rotate by the motor A5, thereby driving the threaded element to rotate, and the rotation direction is opposite to the rotation direction of the subsequent polishing and grinding rod 17, so that the polishing efficiency can be improved;

[0023] The clamping and fixing structure includes a fixed plate 7, an electric cylinder A8, a movable plate 9, a clamping seat A10 and a clamping seat B11. The fixed plate 7, the electric cylinder A8, the movable plate 9, the clamping seat A10 and the clamping seat B11 are each provided with two. The two fixed plates 7 are fixedly installed on the upper end surface of the bearing seat 6, and the two fixed plates 7 are respectively close to the two sides of the bearing seat 6. The electric cylinder A8 is fixedly installed on the fixed plate 7 in a through-type manner. A plurality of guide rods 12 are provided on one side of the movable plate 9. The plurality of guide rods 12 are movably penetrated through the fixed plate 7. One side of the movable plate 9 is connected to the telescopic end of the electric cylinder A8. The two clamping seats A10 are fixedly installed on one side of one of the movable plates 9. The two clamping seats B11 are fixedly installed on one side of the other movable plate 9. The clamping seat A10 and the clamping seat B11 are close to each other. The clamping seat A10 and A concave V-groove is provided on the side where the clamping seats B11 are close to each other, and the two clamping seats A10 and the two clamping seats B11 are designed to be staggered in an up-and-down manner, so that when working, the threaded element can be placed vertically on the supporting seat 6, and then the two electric cylinders A8 are started to drive the two movable plates 9 to move relative to each other, thereby driving the two clamping seats A10 and the two clamping seats B11 to approach each other until the two clamping seats A10 and the two clamping seats B11 cooperate with each other to clamp and fix the threaded element. Due to the V-groove design of the clamping seats A10 and the clamping seats B11, they can be suitable for threaded elements of various sizes, and since the clamping seats A10 and the clamping seats B11 are driven to move and locked by the electric cylinder A8, the clamping and fixing effect of the threaded element is better, the stability of the threaded element is higher, and it is not easy to fall off and affect the processing work.

[0024] The bottom of the bearing seat 6 is slidably connected to the slide groove 3 through a plurality of sliding connectors, so that the stability of the bearing seat 6 during rotation can be improved;

[0025] The inner walls of the V-shaped grooves of the clamping seats A10 and B11 are fitted with rubber cushion layers 13, which can increase the friction between the clamping seats A10 and B11 and the threaded element, thereby further improving the clamping and fixing effect and stability of the threaded element.

The operation of the motor B16 can drive the polishing rod 17 to rotate. Therefore, when working, the electric cylinder B14 and the motor B16 can cooperate to drive the polishing rod 17 to descend and rotate, so as to perform polishing and grinding on the inner groove of the threaded element;

[0027] It is understandable that the polishing rod 17 can be disassembled and replaced according to actual needs so as to match the inner groove size of the threaded element.

[0028] Working principle: During operation, the threaded element can be placed vertically on the supporting seat 6, and then the two electric cylinders A8 are started to drive the two movable plates 9 to move relative to each other, thereby driving the two clamping seats A10 and the two clamping seats B11 to approach each other, until the two clamping seats A10 and the two clamping seats B11 cooperate with each other to clamp and fix the threaded element. Due to the V-groove design of the clamping seats A10 and B11, they can be suitable for threaded elements of various sizes, and since the clamping seats A10 and B11 are both driven to move and locked by the electric cylinder A8, the clamping and fixing effect of the threaded element is better, the threaded element has higher stability, and it is not easy to fall off and affect the processing work. After the fixation is completed, the electric cylinder B14 and the motor B16 can work together to drive the polishing and grinding rod 17 to descend and rotate, and the inner groove of the threaded element can be polished and polished.
