When parts of the starter are required to be machined and ground, firstly, the parts are placed on a workbench 1, then, the parts are fixed on the workbench 1 through a clamping mechanism, then, a cross bar 4 connected to a sliding cavity 3 in a sliding mode is moved, the longitudinal position of a grinding disc 11 on the cross bar 4 is adjusted, then, a moving block 5 connected to the cross bar 4 in a sliding mode is moved, the transverse position of the grinding disc 11 is adjusted, wherein the sliding connection of the moving block 5 on the cross bar 4 is achieved through the arrangement of a sliding block 7 and a sliding groove 6, the sliding block 7 is limited through the sliding groove 6, the moving block 5 is not prone to shake, the moving block 5 can move on the cross bar 4 stably and smoothly, after the grinding position of the parts is determined through the adjustment of the position of the grinding disc 11, an air cylinder 8 located at the top of the moving block 5 is opened, a piston rod moves downwards, and a mounting block 9 is driven to move downwards, so that a first motor, until the grinding disc 11 moved to the output end of the first motor 10 can contact the surface of the part, and then the first motor 10 is turned on, so that the grinding disc 11 starts to rotate, thereby grinding the surface of the part, when the position needs to be changed, the first motor 10 is turned off to stop the grinding disc 11, and then the piston rod of the cylinder 8 is retracted by driving the cylinder 8 to drive the grinding disc 11 to return to the original position, by moving the moving block 5, which is slidably connected to the crossbar 4, laterally, the sanding disc 11 is displaced laterally therewith, by longitudinally moving the cross bar 4, which is slidably connected in the sliding chamber 3, the sanding disc 11 is then longitudinally displaced, therefore, the grinding disc 11 can be used for grinding the surface of the part in all directions, and the working personnel is not required to grind the corners of the part manually, so that the time for finishing grinding the part is shortened, and the grinding efficiency is improved.

When it is desired to move the position of the bar 4 inside the sliding chamber 3, the driving gear 12 inside the sliding chamber 3 is rotated by rotating the end of the transmission rod 13 that protrudes outside the mounting frame 2, thereby causing the chain 14 and the driven gear 15 to rotate therewith, wherein, the driven gear 15 on one end inside the chain 14 is arranged to support and tension the chain 14, so that the chain 14 can stably move in the sliding cavity 3, by providing fixing pins 16 at both ends of bar 4, which are fixedly connected to chain 14, bar 4 can start to move with chain 14 when chain 14 moves, thereby enabling the horizontal bar 4 to start moving along the length direction of the sliding cavity 3, realizing the sliding connection of the horizontal bar 4 in the sliding cavity 3, and the chain 14 transmission has the characteristic of high transmission efficiency, so that the cross bar 4 can slide in the sliding cavity 3 more efficiently.

Because the one end that the transfer line 13 stretches out the outside of mounting bracket 2 is provided with second motor 17, drives transfer line 13 through setting up second motor 17 and rotates, does not need artifical the rotation for transfer line 13's rotation is more convenient, thereby makes transfer line 13 drive gear 12 pivoted operation more stable high-efficient.

Owing to be provided with fixture, when needing centre gripping part, stretch out the outside one end of workstation 1 through rotating screw rod 22, make screw rod 22 rotate along with it, because sliding block 20 and screw rod 22 threaded connection, it is spacing to sliding block 20 through sliding tray 21, make sliding block 20 can't rotate along with it, can only carry out axial motion along screw rod 22's length direction, thereby drive grip block 19 and be close to stopper 18 gradually, and then accomplish the centre gripping to the part, and convenient for operation, and because screw rod 22 and sliding block 20 threaded connection, make sliding block 20 can't remove easily on screw rod 22, make fixture more stable to the centre gripping effect of part.

Because the end of the screw rod 22 extending out of the workbench 1 is provided with the turntable 23, the turntable 23 provides a force application point for the operation of rotating the screw rod 22, so that the operation of driving the sliding block 20 to approach the limiting block 18 by rotating the screw rod 22 is more convenient and labor-saving.

Because a plurality of positioning structures are arranged on the side wall of the cross bar 4, each positioning structure comprises a positioning steel ball 24 protruding out of the side wall of the cross bar 4, and an elastic piece 25 is arranged between the positioning steel ball 24 and the cross bar 4, when the moving block 5 moves to the position of the positioning steel ball 24, the arc surface of the positioning steel ball 24 is firstly contacted with the edge of the side wall of the moving block 5, then the moving block 5 gradually clamps the positioning steel ball 24 into the moving block 5 through the arc surface of the positioning steel ball 24, the positioning steel ball 24 is stressed to retreat, so that the elastic piece 25 contracts and generates elastic force, until the positioning steel ball 24 moves to the caulking groove 26, the positioning steel ball 24 is not extruded by the inner wall of the moving block 5 any more, so that the elastic piece 25 outwards pops the positioning steel ball 24 and clamps the caulking groove 26, the positioning steel ball 24 limits the caulking groove 26, so that the moving block 5 can be stably, when the position of the moving block 5 needs to be changed, the moving block 5 is pushed, the edge of the caulking groove 26 is firstly contacted with the positioning steel balls 24, then the arc surface of the positioning steel balls 24 is gradually separated from the limit of the positioning steel balls 24, the positioning steel balls 24 are extruded by the inner wall of the moving block 5 to return, the elastic part 25 contracts and generates elastic force, when the moving block 5 slides on the cross bar 4, the positioning steel balls 24 also roll on the inner peripheral wall of the moving block 5 until the positioning steel balls are separated from the moving block 5 and return to the original state, so that the fixing of the moving block 5 in the moving position is completed, the operation is convenient, and after the position of the polishing disc 11 is determined by moving the moving block 5, the polishing disc 11 polishes parts, the moving block 5 is not easy to shake, and the polishing effect of the polishing disc 11 is more.

Because the cross section of the cross bar 4 is rectangular, the moving block 5 is limited by the cross bar 4, so that the moving block 5 is not easy to shake and rotate when sliding on the cross bar 4, and the moving block 5 is more stable to move.

Because the mounting bracket 2 is made by stainless steel material, stainless steel material has the characteristics that intensity hardness is high and corrosion resistance is good for 2 intensity of mounting bracket and hardness are higher, difficult damaged and deformation, and corrosion resistance is better, difficult rust, thereby prolonged the life of mounting bracket 2 greatly.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
