Two electromagnets 19 are symmetrically arranged at the bottom of the pillar 11 inside the jig box 1. The magnetism of the electromagnet 19 is transmitted to the magnetic pole 12 through the column. The automobile cover is fixed by magnetic force to prevent the upper and lower clamping fixing method from interfering with the polishing operation. The bottom of the dust channel 18 is slidably connected with the dust collection box 3 for easy cleaning. The collected dust is prevented from environmental pollution. The opening of the dust collection box 3 is located on the side of the fixture box 1. The clamping electric push rods 2 are fixedly connected to the two side surfaces of the fixture box 1. The output end of the clamping electric push rods 2 is fixedly connected to the clamping push plate 8. A polishing device 13 is arranged on the inner side of the top of the fixture box 1. The polishing device 13 includes a first ball screw transmission mechanism 20, a second ball screw transmission mechanism 21, a downward pressing electric push rod 22 and a polishing motor 24. The top of the polishing motor 24 is fixedly connected with a polishing grinding head 25. An electromagnetic three-way valve 4 is arranged at the top center of the fixture box 1. An air pipe joint 6 is arranged at the top center of the electromagnetic three-way valve 4. Air inlet pipes 5 are arranged on both sides of the electromagnetic three-way valve 4. The air inlet pipe 5 passes through the top of the fixture box 1 and is provided with a gas nozzle 7. The dust inside the fixture box 1 is cleaned by pressurized air, which saves labor and improves work efficiency.

[0024] Among them, the first ball screw transmission mechanism 20 is fixed to the inner side of the top of the fixture box 1 by bolts, and the second ball screw transmission mechanism 21 is connected to the slide of the first ball screw transmission mechanism 20 by bolts. The movement directions of the first ball screw transmission mechanism 20 and the second ball screw transmission mechanism 21 are at an angle of 90°, which increases the working range of the polishing motor 24. A downward push rod 22 is fixedly connected to the slide of the second ball screw transmission mechanism 21, and the polishing motor 24 is arranged on the output end of the downward push rod 22. Four guide telescopic rods 23 are arranged between the downward push rod 22 and the polishing motor 24 to ensure that the body of the polishing motor 24 does not rotate;

[0025] Among them, a pair of cover plate slide grooves 15 are connected by bolts at both ends of the side where the feed port of the fixture box 1 is located, and a transparent dust cover plate 14 is slidably connected between the cover plate slide grooves 15, which is convenient for directly observing the polishing progress. An auxiliary handle 16 is provided at the bottom of the outer side of the dust cover plate 14, and a sealing ring 17 is fixedly provided on the inner side of the dust cover plate 14 to prevent the dust inside the fixture box 1 from flying. Positioning rods 26 are provided at the bottom of both sides of the cover plate slide groove 15, and a spring 27 is provided between the cover plate slide groove 15 and the positioning rod 26;

[0026] The gas nozzle 7 is connected to the air inlet pipe 5 by a buckle, and the gas nozzle 7 is symmetrically distributed on both sides of the top of the fixture box 1. The opening of the gas nozzle 7 faces obliquely downward, and the dust inside the fixture box 1 can be cleaned by compressed air.

[0027] Among them, a fixed connecting member 9 is fixedly connected to the clamping surface of the clamping push plate 8, and a triangular notch is provided at the center of the fixed connecting member 9. The triangular notch increases the fixing strength on both sides of the automobile cover body to prevent the automobile cover body from sliding during the polishing process;

[0028] Among them, there are gaps evenly distributed around the magnetic pole 12 and the bottom of the gap is level with the top surface of the magnetic pole 12. When the gas nozzle 7 is used to clean the dust in the fixture box 1, dust is prevented from accumulating in the top groove of the magnetic pole 12.

[0029] The working principle of the utility model is as follows: the auxiliary handle 16 on the outer bottom of the dust cover 14 is pressed down to move the dust cover 14 downward, and the automobile cover to be polished is placed into the center position of the inside of the fixture box 1 while stepping on the auxiliary handle 16 with the foot, and the power supply of the electromagnet 19 is started. The magnetism of the electromagnet 19 is transmitted to the magnetic pole 12 through the column, so that the automobile cover is adsorbed on the magnetic pole 12, and the clamping electric push rods 2 located on both sides of the fixture box 1 work to push the clamping push plate 8 close to the two sides of the automobile cover, and the fixing connecting piece 9 on the top of the clamping push plate 8 fixes the automobile cover.

At the same time, the first ball screw transmission mechanism 20 and the second ball screw transmission mechanism 21 work to drive the polishing motor 24 to move in the horizontal direction to achieve polishing of the automobile cover. During the polishing operation, the electromagnetic three-way valve 4 is started, and the gas nozzle 7 on the other side of the top of the fixture box 1 where the polishing motor 24 is located works to blow the dust generated by polishing away from the automobile cover to prevent scratching the polishing surface. When the polishing is completed and the polished automobile cover is taken out, the electromagnetic three-way valve 4 is opened alternately, and the gas nozzle 7 on the top of the fixture box 1 works alternately to blow the dust on the side of the fixture box 1 and the top of the magnetic pole 12 to the guide slope 10.
