[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example

[0022] See also Figures 1 to 4 , is an embodiment of the present utility model, which provides a technical solution: a clamping structure of a motor housing processing punch, comprising

[0023] Two base columns 1 are vertically penetrated at the edges of both sides of the punch processing table 8, a cross bar 2 is horizontally penetrated at the top of the base column 1, an arc-shaped clamping block 3 is welded and fixed to one end of the cross bar 2, and a fastening bolt 5 is threadedly set on the top surface of the base column 1 and the bottom end is tightly abutted against the cross bar 2. A motor housing blank 7 is clamped between the two arc-shaped clamping blocks 3. The bottom end of the base column 1 penetrates to the bottom of the punch processing table 8, and the top end of the base column 1 penetrates to the top of the punch processing table 8;

[0024] And the height adjustment mechanism 6 arranged between the punch processing table 8 and the base column 1, including an L-shaped side plate 61 movably installed on the side of the punch processing table 8, a limit clamping rod 62 welded and fixed to the bottom end surface of the L-shaped side plate 61, and a plurality of limit clamping holes 63 opened on the surface of the base column 1. The limit clamping rod 62 is inserted into one of the limit clamping holes 63. When actually used, the motor housing blank 7 is first placed on the top center of the punch processing table 8, and then the height of the arc clamping block 3 is adjusted by the height adjustment mechanism 6 according to the height of the motor housing blank 7 to ensure that the arc clamping block 3 is at an appropriate height. Then adjust the position of the arc clamping block 3 according to the size of the motor housing blank 7. When adjusting, just loosen the fastening bolt 5 counterclockwise to release the limit on the cross bar 2, and then move the cross bar 2 horizontally so that the arc rubber pad 4 on the inside of the arc clamping block 3 contacts and fits with the surface of the motor housing blank 7, and then tighten the fastening bolt 5 clockwise to fix the cross bar 2. The two symmetrical arc clamping blocks 3 can effectively clamp and limit the motor housing blank 7, thereby ensuring the stability of the motor housing blank 7 during subsequent punching processing, and ensuring processing accuracy and efficiency.

[0025] Among them, the height adjustment mechanism 6 also includes an inner slide groove 64 opened inside the punch processing table 8, an inner slide plate 66 installed in the inner slide groove 64, and an inner connecting rod 65 welded and fixed to the surface of one side of the inner slide plate 66. The end of the inner connecting rod 65 passes through the side of the punch processing table 8 and is fixed to the L-shaped side plate 61. Two springs 67 are also installed between the inner slide plate 66 and the inner wall of the inner slide groove 64. Under the push of the spring 67, the L-shaped side plate 61 can remain in close contact with the side of the punch processing table 8 during daily use, thereby ensuring that the limit card rod 62 can be stably inserted into the limit card hole 63 to ensure the limiting stability of the base column 1. To adjust the height of the arc clamping block 3 laterally, it is only necessary to pull the L-shaped side plate 61 sideways so that the inner connecting rod 65 can move The inner slide 66 moves sideways and compresses the spring 67, causing the end of the limit rod 62 to move out of the limit hole 63, and the limit on the base column 1 can be released. At this time, the base column 1 can be slid up and down for height adjustment, so that the arc clamping block 3 can adapt to motor housing blanks 7 of different heights. When the arc clamping block 3 is adjusted to a suitable height, the L-shaped side plate 61 is released, and the spring 67 will push the inner slide 66 back to reset, and make the L-shaped side plate 61 rebound with the limit rod 62, and finally make the end of the limit rod 62 inserted into the limit hole 63 at other positions, and the base column 1 can be limited again, thereby completing the adaptive adjustment of the height of the arc clamping block 3 to ensure that the motor housing blanks 7 of different heights can be effectively clamped.

[0026] Among them, side holes communicating with the inner slide groove 64 are opened on both side surfaces of the punch processing table 8, and the side holes correspond to the inner connecting rod 65, allowing the inner connecting rod 65 to pass through smoothly.

[0027] Among them, two cylindrical mounting grooves are opened on the side of the inner slide 66, one end of the spring 67 is fixed in the cylindrical mounting groove, and the other end of the spring 67 is fixed to the inner wall of the inner slide groove 64 to ensure the stable installation of the spring 67.

[0028] Among them, a threaded hole corresponding to the fastening bolt 5 is opened on the top surface of the base column 1, and the bottom end of the fastening bolt 5 is screwed into the threaded hole and fixed to the surface of the cross bar 2. At the later stage, the fastening bolt 5 can be loosened by rotating counterclockwise to release the limit of the fastening bolt 5 on the cross bar 2. At this time, the cross bar 2 can be slid horizontally to change the position of the arc clamping block 3, thereby changing the distance between the two arc clamping blocks 3, so as to effectively clamp the motor housing blanks 7 of different sizes.

[0029] Among them, the inner wall of the arc-shaped clamping block 3 is installed with an arc-shaped rubber pad 4, and the arc-shaped rubber pad 4 is in close contact with the surface of the motor housing blank 7, which can improve the clamping stability of the arc-shaped clamping block 3 on the motor housing blank 7 and play a certain anti-slip role.

[0030] Among them, the surface of the arc-shaped rubber pad 4 is provided with a plurality of L-shaped clips 41, and the surface of the arc-shaped clamping block 3 is provided with a plurality of disassembly holes 31 corresponding to the L-shaped clips 41. The ends of the L-shaped clips 41 pass through the disassembly holes 31 to the outer surface of the arc-shaped clamping block 3, which can stably limit the arc-shaped rubber pad 4 and ensure the installation stability of the arc-shaped rubber pad 4. The arc-shaped rubber pad 4 and the L-shaped clips 41 are an integrated structure. Both are made of rubber material and will undergo elastic deformation when squeezed.

[0031] Although embodiments of the present invention have been shown and described (see the detailed description above for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
