The workpiece can be polished more finely by the grinding assembly 3. The grinding belt 35 in operation can be cooled by the cooling and cleaning assembly 4 to prevent the surface of the grinding belt 35 from becoming soft due to the increase in temperature. At the same time, after the work of the grinding belt 35 is completed, the surface of the grinding belt 35 can be cleaned to prevent dust from being left behind, thereby improving the practicality of the device.

[0029] like Figure 3 and Figure 4 As shown, the fixed clamping assembly 2 includes a workbench 21, the left and right sides of the workbench 21 are fixedly installed at the bottom position of the left and right inner walls of the box body 1, and a mounting groove 22 is opened at the upper end of the workbench 21. The inner wall of the mounting groove 22 is rotatably connected with a reverse double-threaded rod 23 that passes through the right part of the box body 1, and a handwheel 24 is fixedly installed at the right end of the reverse double-threaded rod 23. The left and right parts of the outer wall of the reverse double-threaded rod 23 are both threadedly connected with sliders 25.

[0030] By rotating the hand wheel 24 , the reverse double-threaded rod 23 is rotated, and the two sliders 25 are threadedly connected with the reverse double-threaded rod 23 to move closer to or farther from each other.

[0031] like Figure 5 As shown, a mounting plate 26 is fixedly mounted on the upper ends of the two sliders 25 , a plurality of spring guide shafts 27 are fixedly mounted on the opposite sides of the two mounting plates 26 , and a fixing head 28 is fixedly mounted on the opposite ends of a plurality of adjacent spring guide shafts 27 .

[0032] The two slide blocks 25 can drive the two mounting plates 26 to approach each other to quickly clamp and fix the workpiece on the workbench 21. When the plurality of spring guide shafts 27 contact the surface of the heterogeneous workpiece, their elastic restoring force can drive the plurality of fixing heads 28 to quickly fix the heterogeneous workpiece, thereby improving the overall processing rate of the device.

[0033] like Figure 6 As shown, the grinding assembly 3 includes a cylinder 31, the lower end of the cylinder 31 is fixedly installed on the upper right part of the box body 1, the output end of the cylinder 31 passes through the top of the box body 1 and is fixedly installed with a mounting frame 32, and a limiting telescopic rod 33 is fixedly installed on the upper left part of the box body 1, and the output end of the limiting telescopic rod 33 passes through the top of the box body 1 and is fixedly connected to the upper left part of the mounting frame 32.

[0034] The mounting frame 32 is driven to move up and down by the output end of the cylinder 31 , and the limiting telescopic rod 33 is extended and retracted following the movement of the mounting frame 32 , which has a limiting effect on the movement of the mounting frame 32 .

[0035] like Figure 6 As shown, the left and right parts of the inner wall of the mounting frame 32 are rotatably connected with toothed rollers 34, the outer surfaces of the two toothed rollers 34 are transmission-sleeved with grinding belts 35, and the inner peripheral wall of the grinding belt 35 is provided with a plurality of tooth grooves matching the two toothed rollers 34. A motor 36 is fixedly installed on the rear right part of the mounting frame 32, and the output end of the motor 36 passes through the rear part of the mounting frame 32 and is fixedly connected to the rear end of the toothed roller 34 located on the right part.

[0036] The outer surfaces of the two toothed rollers 34 are fixedly mounted with a plurality of teeth arranged in a ring form. The output end of the motor 36 drives the toothed roller 34 on the right to rotate. The two toothed rollers 34 rotate due to the transmission action of the grinding belt 35. The grinding belt 35 moves due to the cooperation with the two toothed rollers 34. The outer peripheral surface of the grinding belt 35 is provided with grinding material, so that the workpiece can be polished.

[0037] like Figure 7 As shown, the cooling and cleaning component 4 includes a water tank 41, the lower end of the water tank 41 is fixedly installed with the middle part of the upper end of the mounting frame 32, the lower end of the water tank 41 is fixedly installed with a drip pipe 42 that passes through the top of the mounting frame 32, and the inner cavity of the drip pipe 42 is fixedly installed with a valve 43.

[0038] The water in the water tank 41 leaks out from the dripping pipe 42, and the valve on the dripping pipe 42 can control the opening and closing of the dripping pipe 42. Wherein the water tank 41 upper right part is fixedly installed with a water inlet bucket, and the staff can replenish water for the water tank 41 from the water inlet bucket.

[0039] like Figure 7 As shown, an electric push rod 44 is fixedly installed at the front position of the top of the inner wall of the mounting frame 32, and a movable plate 45 is fixedly installed at the output end of the electric push rod 44. A telescopic rod 46 is fixedly installed at the rear position of the top of the inner wall of the mounting frame 32, and the output end of the telescopic rod 46 is fixedly connected to the front upper end of the movable plate 45. A water-absorbing sponge 47 is fixedly installed at the lower end of the movable plate 45. A through groove is opened in the middle part of the upper end of the movable plate 45, and the drip pipe 42 is located directly above the through groove.

[0040] The output end of the electric push rod 44 can drive the moving plate 45 to move up and down, and the telescopic rod 46 limits the movement of the moving plate 45. The drip pipe 42 can inject water into the water-absorbing sponge 47 through the through groove when the valve 43 is opened. The water-absorbing sponge 47 can properly moisten and cool the grinding belt 35. The water-absorbing sponge 47 is glued to the lower end of the moving plate 45 by glue. After the water-absorbing sponge 47 works for a period of time, the staff can tear it off with tools.

[0041] like Figure 2 and Figure 7 As shown, a vacuum cleaner 48 is fixedly installed in the middle of the right side of the box body 1, the input end of the vacuum cleaner 48 passes through the right side of the box body 1 and is fixedly installed with a vacuum tube 49, and a plurality of vacuum heads arranged linearly are fixedly installed on the left side of the outer wall of the vacuum tube 49.

[0042] The vacuum cleaner 48 is an existing mechanism, which has a high-speed rotating drive motor installed inside. When the motor is started, it drives the fan blades to rotate at high speed. The rotation of the fan blades will generate high-speed airflow inside the vacuum cleaner 48, which will reduce the air pressure inside the vacuum cleaner 48. The dust generated by grinding is sucked into the vacuum cleaner 48 through a number of suction heads. Among them, the vacuum cleaner 48 can be automatically cleaned.

[0043] The working principle of the utility model is as follows: the staff opens the box door, places the workpiece to be polished on the workbench 21, and turns the handwheel 24, the handwheel 24 drives the reverse double-threaded rod 23 to rotate, and the two sliders 25 drive the two mounting plates 26 to approach each other through threaded connection with the reverse double-threaded rod 23, and several spring guide shafts 27 drive the corresponding fixed heads 28 to quickly clamp and fix the workpiece. If the workpiece is a special-shaped workpiece, the elastic restoring force of the several spring guide shafts 27 can drive the fixed heads 28 to act on different surfaces of the special-shaped workpiece, thereby improving the fixing efficiency of the workpiece.

[0044] Then, the cylinder 31, the motor 36 and the vacuum cleaner 48 are started. The output end of the cylinder 31 drives the mounting frame 32 to move, and the mounting frame 32 drives the grinding belt 35 to move until it contacts the surface of the workpiece. At the same time, the motor 36 drives the toothed roller 34 on the right to rotate, so that the grinding belt 35 is transmitted by meshing with the two toothed rollers 34, so that the workpiece can be precisely ground.

[0045] During the grinding process of the workpiece, the valve 43 is opened, and water flows from the drip pipe 42 through the through groove to the water-absorbing sponge 47 to wet the water-absorbing sponge 47. Then the valve 43 is closed, and the electric push rod 44 is started. Its output end drives the moving plate 45 and the water-absorbing sponge 47 to move until the water-absorbing sponge 47 contacts the grinding belt 35, and slightly wets the surface of the grinding belt 35, thereby cooling the grinding belt 35. At the same time, the water-absorbing sponge 47 can also clean the dust on the outer peripheral surface of the grinding belt 35.

[0046] At the same time, the vacuum cleaner 48 sucks away the dust generated by the grinding of the workpiece through a plurality of vacuum heads to prevent the dust from polluting the internal environment of the box body 1.
