DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0023] Reference Figure 1-3 , an end face polishing device for processing stator and rotor punching sheets, comprising a support 1, a limiting mechanism and a polishing mechanism installed on the support 1, the limiting mechanism comprising a limiting component 1 and a limiting component 2, the limiting component 1 comprising a motor 1 2, a lead screw 3, a motor 2 4, a turntable 1 5, a cylinder 6, a connecting seat 7, a turntable 2 8 and a limiting column 19, the lead screw 3 is installed at the output end of the motor 1 2, the motor 2 4 is arranged in two groups, and is connected to the two ends of the lead screw 3 through a connecting plate transmission, the turntable 1 5 is installed at the output end of the motor 2 4, the cylinder 6 is arranged in two groups, which are respectively oppositely slid on the upper end of the support 1 through a slide seat, and are arranged one by one with the two groups of motors 2 4, the connecting seat 7 is fixedly installed at the output end of the cylinder 6, the turntable 2 8 is rotatably installed at the bottom of the connecting seat 7, and the limiting column 19 is fixedly installed in the middle of the turntable 1 5, and passes through the connecting seat 7 and the turntable 2 8;

[0024] The second limiting assembly includes a spring barrel 11, a baffle 12, a handle 13, a limiting seat 14, a stud 15 and a swivel 16. One end of the spring barrel 11 is mounted on the support 1 through the fixing seat 10, the baffle 12 is mounted on the other end of the spring barrel 11, the handle 13 is mounted on the baffle 12, the limiting seat 14 is mounted on the support 1, and its opening is set toward the spring barrel 11. The stud 15 is slidably set on the limiting seat 14 and locked on the limiting seat 14 by a nut. The swivel 16 is rotatably mounted on the stud 15;

[0025] The polishing mechanism includes a hydraulic cylinder 17 and a polishing machine 18. The hydraulic cylinder 17 is installed on the top of the support 1, and the polishing machine 18 is installed at the output end of the hydraulic cylinder 17. After the stator and rotor punchings are polished, the hydraulic cylinder 17 can be driven to pull the polishing machine 18 upward. At this time, the handle 13 can be pulled, and the distance between the baffle 12 and the stator and rotor punchings is increased to facilitate the removal of the stator and rotor punchings.

[0026] A tray 9 is rotatably mounted on the fixed seat 10, and the polishing sheet at the output end of the polishing machine 18 is set to be offset from the center of the tray 9; after the stator and rotor punchings are placed on the tray 9, the polishing sheet at the bottom of the polishing machine 18 is located on the upper side of the stator and rotor punchings. When the stator and rotor punchings rotate, the polishing machine 18 can polish the stator and rotor punchings. It should be noted that the stator and rotor punchings are limited by the turntable 1 5 and the turntable 2 8, and the motor 2 4 is a reduction motor. When the motor 2 4 drives the stator and rotor punchings to rotate through the turntable 1 5, the stator and rotor punchings also rotate at a slow speed, giving the polishing machine 18 more time to polish the stator and rotor punchings.

[0027] A fixing ring 501 is installed at the top end of the turntable 1 5, and a distance is left between the outer wall of the fixing ring 501 and the outer wall of the turntable 1 5, and a ring groove matching the size of the fixing ring 501 is opened on the bottom surface of the turntable 2 8; after the turntable 2 8 moves downward, the ring groove can be buckled on the fixing ring 501, so that the turntable 2 8 can continue to move downward a certain distance, thereby applying pressure to the punching sheet, and when the motor 2 4 drives the turntable 1 5, it can drive the punching sheet to rotate.

[0028] The vertical section of the limit seat 14 is arranged in an E-shaped structure as a whole, and the tray 9 is at the horizontal position where the swivel 16 is located; after the punch is placed on the tray 9, when it moves in the horizontal direction, the punch can contact the swivel 16, because the swivel 16 and the stud 15 are rotatably connected, it can assist the punch to rotate.

[0029] Working principle: When used for the first time, pull the handle 13 to drive the baffle 12 to extend the spring tube 11. At this time, the punch can be placed on the tray 9. Release the handle 13, the spring tube 11 shrinks, and drives the baffle 12 to contact the edge of the punch. Then move the position of the stud 15 on the limit seat 14 so that the swivel 16 in the middle of the stud 15 contacts the edge of the punch. Then lock the stud 15 on the limit seat 14 through the nut. At this time, both sides of the punch are restricted;

[0030] The driving motor 1 2 drives the two motors 2 4 to make relative movement through the screw 3, so that the fixing rings 501 at the top ends of the two turntables 1 5 are fitted on both sides of the punching sheet. When the motor 2 4 is moved, the two cylinders 6 are moved by hand synchronously, and then the cylinder 6 is driven to push the connecting seat 7 to move downward, so that the ring groove at the bottom of the turntable 2 8 is correspondingly buckled on the fixing ring 501, so that the two lower end faces of the punching sheet are fitted by the turntable 2 8 and the turntable 1 5. (It should be noted that the turntable 2 8 and the turntable 1 5 do not need to clamp the punching sheet, but only need to fit the turntable 2 8 and the turntable 1 5 at the upper and lower end faces of the punching sheet, and the turntable 2 8 applies a certain pressure to the punching sheet. When the motor 2 4 drives the turntable 1 5 to rotate, the friction between the turntable 2 8 and the turntable 1 5 and the punching sheet is sufficient to drive the punching sheet to rotate);

[0031] After completing the above operations, the motor 2 4 can be driven to drive the turntable 1 5 to rotate, and the hydraulic cylinder 17 can be driven to push 18 to move downward, and the punching sheet 18 can be driven to grind and polish.

[0032] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
