[0027] Mounting seats 17 are symmetrically arranged on both sides of the pedestal 3 , a cylinder 18 is arranged inside the mounting seat 17 , a piston rod 19 is arranged at the output end of the cylinder 18 , and one end of the piston rod 19 is connected to the clamping plate 4 .

[0028] A pull sleeve 20 is provided on one side of the installation sleeve 11 , and the pull sleeve 20 is fixedly connected to the top end of the slide rod 14 .

[0029] A driving assembly 21 is disposed on the pedestal 3 , and the insert sleeve 9 is fixedly connected to the output end of the driving assembly 21 .

[0030] A handle 22 is provided on one side of the mounting plate 6 , and the handle 22 is fixedly connected to the one side of the mounting plate 6 .

[0031] In this embodiment, when the device needs to be used to polish mechanical parts, the corresponding parts are first placed on the workbench 2, and then the two cylinders 18 are opened synchronously. The cylinder 18 drives the clamping plate 4 to move through the piston rod 19 connected to the output end, and then the two clamping plates 4 will stably clamp the parts. After accommodating them, the cylinder 18 is closed, and the drive assembly 21 installed on the base 3 is opened, so that the drive assembly 21 drives the polishing wheel 5 connected to the output end to run, thereby realizing the polishing processing of the mechanical parts. When the polishing wheel 5 needs to be replaced, the pull sleeve 20 is first pulled, so that the pull sleeve 20 drives multiple slide rods 14 to move, and then one end of the slide rod 14 will slide out of the positioning groove 12, and at the same time, the slide rod 14 will squeeze the spring 13 set on the outside, and then the mounting plate 6 and the mounting rod 7 are rotated through the handle 22, and the mounting rod 7 will drive the matching groove 16 set on the inside to Rotation, due to the unique variable diameter structure design of the matching groove 16, when the matching groove 16 moves, the variable diameter plate will drive the clamping rod 8 to gradually disengage from the clamping groove 10. When the handle 22 can no longer drive the mounting plate 6 and the mounting rod 7 to rotate, one end of the clamping rod 8 will completely disengage from the clamping groove 10. Then, by pulling the mounting rod 7 by the handle 22, the mounting rod 7 and the mounting sleeve 11 can be disengaged from the insertion sleeve 9 together. Then, the polishing wheel 5 can be quickly disassembled, and then the corresponding polishing wheel 5 can be reinstalled to the corresponding position. Then, refer to the above steps to fix the polishing wheel 5 at the output end of the drive assembly 21, and then release the pull sleeve 20. The spring 13 will push the slide rod 14 to engage in the original positioning groove 12, thereby limiting the mounting plate 6 and the mounting rod 7 and preventing unnecessary movement of the mounting rod 7, thereby achieving quick and stable installation of the polishing wheel 5.

[0032] See also Figure 1 As an implementation method of a precision mechanical parts polishing device for a mobile device: the mobile device includes a base plate 23 and a universal wheel 24, the base plate 23 is installed at the bottom end of the fixed seat 1, and the universal wheel 24 can be movably installed below the base plate 23.

[0034] A rotating rod 27 is provided at the top of the screw rod 25 , and the rotating rod 27 is fixedly connected to the top of the screw rod 25 .

[0035] More specifically, when the device needs to be moved, the screw rod 25 is first rotated by the rotating rod 27, so that the screw rod 25 drives the support plate 26 to move upward, and then the device as a whole will lose its limit, and then the device is directly pushed so that the device moves through the universal wheel 24 installed under the base plate 23. When moving to the device, the rotating rod 27 is rotated in the opposite direction, so that the screw rod 25 drives the support plate 26 to descend, and then the support plate 26 is firmly supported on the ground, effectively preventing the device from moving.

[0036] In summary, when the device is in use: first place the corresponding parts on the workbench 2, and then open the two cylinders 18 synchronously. The cylinder 18 drives the clamping plate 4 to move through the piston rod 19 connected to the output end, and then the two clamping plates 4 will stably clamp the parts. After accommodating, close the cylinder 18, and open the drive assembly 21 installed on the base 3, so that the drive assembly 21 drives the polishing wheel 5 connected to the output end to run, thereby realizing the polishing processing of the mechanical parts. When the polishing wheel 5 needs to be replaced, first pull the pull sleeve 20 so that the pull sleeve 20 drives multiple slide rods 14 to move, and then one end of the slide rod 14 will slide out of the positioning groove 12, and at the same time, the slide rod 14 will squeeze the spring 13 set on the outside, and then rotate the mounting plate 6 and the mounting rod 7 through the handle 22, and the mounting rod 7 will drive the matching groove 16 set on the inside to rotate. 6 Unique variable diameter structure design, when the matching groove 16 moves, the variable diameter plate will drive the clamping rod 8 to gradually disengage from the clamping groove 10, when the handle 22 can no longer drive the mounting plate 6 and the mounting rod 7 to rotate, one end of the clamping rod 8 is completely disengaged from the clamping groove 10, and then the mounting rod 7 is pulled by the handle 22, so that the mounting rod 7 and the mounting sleeve 11 can be disengaged from the insertion sleeve 9 together, and then the polishing wheel 5 can be quickly disassembled, and then the corresponding polishing wheel 5 can be reinstalled to the corresponding position, and then the polishing wheel 5 is fixed to the output end of the driving assembly 21 according to the above steps, and then the pull sleeve 20 is released, and the spring 13 will push the slide rod 14 to engage in the original positioning groove 12, so as to limit the mounting plate 6 and the mounting rod 7, prevent the mounting rod 7 from unnecessary movement, and thus achieve fast and stable installation of the polishing wheel 5.

[0037] When the device needs to be moved, the screw rod 25 is first rotated by the rotating rod 27, so that the screw rod 25 drives the support plate 26 to move upward, and then the device as a whole will lose its limit, and then the device is directly pushed so that the device can be moved through the universal wheel 24 installed under the base plate 23. When moving to the device, the rotating rod 27 is rotated in the opposite direction, so that the screw rod 25 drives the support plate 26 to descend, and then the support plate 26 is firmly supported on the ground, effectively preventing the device from moving.
