The top of the vertical screw is located below the middle of the lifting plate above the horizontal fixed plate. A vertical screw sleeve is fixed in the middle of the bottom surface of the lifting plate. The top of the vertical screw is screwed into the vertical screw sleeve. The output shaft of the lifting servo motor is a spline shaft, which is inserted into the spline hole at the bottom of the vertical screw and drives the vertical screw to rotate. Multiple vertical guide rods are fixed on the bottom surface of the lifting plate. The lower part of the vertical guide rod is inserted into the corresponding guide sleeve, and its outer side wall is in close contact with or near the inner side wall of the corresponding guide sleeve.

[0009] Above the lifting plate is a support frame device for placing the motor stator to be processed.

[0022] For example, see below. Figures 1 to 6 As shown, a fixture for inserting paper into a motor stator includes a bottom frame 10. Multiple transverse connecting plates 19 are fixed to the lower parts of the front and rear side walls of the bottom frame 10. A central through hole is formed in the middle of each transverse connecting plate 19. A bottom pressing block 191 is located directly below the transverse connecting plate 19. An anti-slip layer 192 is fixed to the bottom surface of the bottom pressing block 191, and the bottom surface of the anti-slip layer 192 presses against the ground. A threaded post 193 is formed in the middle of the top surface of the bottom pressing block 191. A lower nut is threaded onto the lower part of the threaded post 193, and the top surface of the lower nut presses against the bottom surface of the transverse connecting plate 19. The top of the threaded post 193 extends beyond the top of the central through hole and is fitted with a washer and a locking nut 194 is threaded onto it. The washer is clamped between the locking nut 194 and the top surface of the transverse connecting plate 19.

[0023] This structure allows you to loosen the locking nut 194 and then rotate the lower nut to adjust the height of the bottom pressure block 191, thus achieving a leveling effect. After adjustment, simply tighten the lower nut and the locking nut 194. The adjustment is very convenient.

[0024] Furthermore, a horizontal plate 11 is fixed to the top left side of the bottom frame 10. The front and rear sides of the top surface of the horizontal plate 11 are both fixed with left and right extending movable guide rails 12. The horizontal fixed plate 20 is located above the two movable guide rails 12. The front, rear left and right sides of the bottom surface of the horizontal fixed plate 20 are both fixed with sliders 21. The movable guide rails 12 are inserted into the grooves of the corresponding sliders 21.

[0025] Guide sleeves 22 are fixed to the left and right front and rear parts of the top surface of the horizontal fixed plate 20. The guide sleeves 22 are connected to and aligned with the corresponding vertical through holes formed on the horizontal fixed plate 20. The vertical through holes are located in the middle of the horizontal plate 11, which is formed in the center through groove 111 and corresponds to the lower center through groove of the bottom frame 10.

[0026] A lifting servo motor 23 is fixed in the middle of the bottom surface of the horizontal fixed plate 20. A vertical screw 24 is movably connected to the middle of the top surface of the horizontal fixed plate 20 through a bearing. The top of the vertical screw 24 is located below the middle of the lifting plate 30 above the horizontal fixed plate 20. A vertical screw sleeve 31 is fixed in the middle of the bottom surface of the lifting plate 30. The top of the vertical screw 24 is screwed into the vertical screw sleeve 31. The output shaft of the lifting servo motor 23 is a spline shaft, which is inserted into the spline hole at the bottom of the vertical screw 24 and drives the vertical screw 24 to rotate. A plurality of vertical guide rods are fixed on the bottom surface of the lifting plate 30. The lower part of the vertical guide rod 1 is inserted into the corresponding guide sleeve 22, and its outer side wall is in close contact with or close to the inner side wall of the corresponding guide sleeve 22.

[0027] Above the lifting plate 30 is a support frame device 40 for placing the motor stator 100 to be processed.

[0028] The paper inserter is fixed on the top right side of the bottom frame 10. It is a conventional structure and will not be described in detail here.

[0029] Furthermore, the support frame device 40 includes an upper rotating plate 41, which is movably connected to the top surface of the lifting plate 30 via a hinge shaft.

[0030] The front and rear parts of the top surface of the upper rotating plate 41 are fixedly connected to the front side frame 43 and the rear side frame 44 by adjusting bolts 42.

[0031] Both the front frame 43 and the rear frame 44 include bottom transverse plates 45 extending to the left and right. Connecting frames are fixed to the left and right sides of the top surface of the bottom transverse plates 45. The two ends of the transverse guide rollers 46 extending to the left and right are movably connected to the two connecting frames through bearings. The motor stator 100 rests against the two transverse guide rollers 46.

[0032] Side positioning blocks 32 are fixed to the left, right, front and rear of the lifting plate 30. A positioning recess 33 is formed in the middle of the top surface of the side positioning block 32. A vertical connecting column 47 is fixed to the bottom left of the upper rotating plate 41. A screw hole is formed in the middle of the bottom surface of the vertical connecting column 47. A ball plunger 48 is screwed into the screw hole. The ball at the bottom of the ball plunger 48 extends out of the bottom end of the vertical connecting column 47 and is nested in the corresponding positioning recess 33.

[0033] Furthermore, the bottom transverse plate 45 is formed with a plurality of waist-shaped through holes 451 extending back and forth. The screw part of the adjusting bolt 42 is inserted into the corresponding waist-shaped through hole 451 and screwed into the corresponding screw hole on the lifting plate 30. The bottom surface of the rotating part of the adjusting bolt 42 presses against the top surface of the corresponding bottom transverse plate 45, and the bottom surface of the bottom transverse plate 45 presses against the top surface of the lifting plate 30.

[0034] This structure allows for adjustment of the distance and position between the front frame 43 and the rear frame 44 simply by loosening the corresponding adjusting bolt 42 to meet usage requirements. After adjustment, tighten the adjusting bolt 42.

[0035] Furthermore, the lifting servo motor 23 is inserted into the central through slot 111 of the horizontal plate 11 and the lower central through slot of the bottom frame 10.

[0036] A sensing protrusion 2 is fixed on the outer wall of the slider 21 on the left side of the horizontal fixed plate 20. A proximity switch 3 is fixed on the front or rear part of the left side of the horizontal plate 11, and the sensing end of the proximity switch 3 corresponds to the sensing protrusion 2.

[0037] In this embodiment, all electrical components are electrically connected to the control host via electrical connection lines. This is a conventional structure and will not be described in detail here.

[0038] In this embodiment, the stator 100 to be processed can be placed on two transverse guide rollers 46. The lifting servo motor 23 is run to adjust the height of the lifting plate 30 so that the stator 100 corresponds to the connecting shaft at the left end of the paper inserter. Then, by manually pushing, the lifting plate 30 and all its components are moved to the right so that the stator 100 is inserted into the connecting shaft. Then, the lifting servo motor 23 is run to lower the lifting plate 30 back to its original position. Then, the lifting plate 30 and its components are moved to the left until they are against the limiting plate fixed on the top left side of the horizontal plate 11. At this time, the sensing end of the proximity switch 3 is close to the sensing protrusion 2 to achieve sensing, indicating that the lifting plate 30 and related components are in the initial position.

[0039] After the paper insertion is completed, the lifting plate 30 is lifted and then moved to the bottom of the connecting shaft. The stator 100 with the paper inserted is then removed onto the two transverse guide rollers 46. Then, it is moved back to its original position and can be taken away. This is very convenient and greatly reduces the amount of manual labor. It is easy to use and operate.

[0040] Meanwhile, during use, there will be a material picking device or material picking and placing rack on the front or right side. At this time, the support frame device 40 can be rotated so that the stator 100 faces forward or backward. At this time, the ball at the bottom of the ball head plunger 48 will be nested in the corresponding positioning recess 33 to achieve positioning, so that its rotation position is fixed and the rotation position is accurate.

[0041] Meanwhile, the bottom surface of the horizontal fixed plate 20 in this embodiment can also be fixed with a push block, and a transverse push cylinder is fixed at the lower part of the bottom frame 10. The end of the push rod of the transverse push cylinder is attached to the push block. It can move the horizontal fixed plate 20 and its components to the left or right by retracting or pushing the push rod of the transverse push cylinder, thus realizing automatic movement. This is a commonly used automatic operation structure and method, which will not be described in detail here (the transverse push cylinder and other components are not installed in this embodiment).

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
