[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figures 1-4As shown, this utility model provides a DC high-voltage contactor housing processing and fixing device for quick model change, including a fixing mechanism 1. A limiting mechanism 2 is provided at the lower end of one side of the fixing mechanism 1. The fixing mechanism 1 includes a base frame 11. A motor 12 is fixedly installed at the upper end of one side of the base frame 11. The output end of the motor 12 rotatably passes through the base frame 11 and a rotating plate 13 is fixedly sleeved at its end. A rotating cylinder 112 is integrally formed in the middle of the rotating plate 13, and the rotating cylinder 112 is rotatably sleeved on the outer side of the output end of the motor 12. On one side, the end of the rotating drum 112 is rotatably inserted into the base frame 11. A side cylinder 113 is fixedly installed on the upper side of one side of the base frame 11, and the end of the rotating drum 112 is rotatably inserted into the side cylinder 113. The cooperation between the rotating drum 112 and the side cylinder 113 ensures the stable rotation of the rotating plate 13. A double-ended stud 14 is rotatably inserted into the middle of the rotating plate 13, and a screw cylinder 117 is threaded onto the outer side of the double-ended stud 14. A matching handwheel 114 is fixedly fitted on the double-ended stud 14, and the handwheel 114 has a symmetrical structure. The handwheel 114 has an array of grooves 115 on its outer wall. The grooves 115 increase friction and facilitate operation. Supports 15 are fixedly installed at the opposite ends of the two screw cylinders 117. A top bolt 16 is threaded into the center of one side of the rotating plate 13, and the end of the top bolt 16 can tightly abut against the outer wall of the double-ended stud 14. Guide cylinders 17 are fixedly inserted into both ends of the rotating plate 13, and symmetrically distributed guide rods 18 are slidably inserted into the guide cylinders 17. The ends of adjacent guide rods 18 are connected to... The support frame 15 is fixedly connected, and the inner bottom end of the base frame 11 is detachably inserted with a material frame 19 for use. An electric push rod 110 is fixedly installed on the upper end of the other side of the base frame 11, and the output end of the electric push rod 110 slides through the base frame 11 and is fixedly connected to a clamping plate 111 for use at its end. A sliding rod 116 is fixedly installed on the lower end of one side of the clamping plate 111, and the sliding rod 116 is slidably inserted into the base frame 11. The setting and use of the sliding rod 116 plays a limiting and guiding role in the movement adjustment of the clamping plate 111.

[0019] By adopting the above technical solution, during use, the distance between the two supports 15 is adjusted according to the actual size of the DC high-voltage contactor housing to be stamped. At this time, the top bolt 16 needs to be turned, and when the end of the top bolt 16 is separated from the double-ended stud 14, one of the handwheels 114 can be rotated arbitrarily. This will drive the double-ended stud 14 to rotate, thereby enabling the two screw cylinders 117 to move easily in opposite directions or back to back. Furthermore, this will enable the two supports 15 to move easily in opposite directions or back to back. When the distance between the back sides of the two supports 15 matches the housing to be stamped, stop rotating the handwheel 114 and turn the top bolt 16 in the opposite direction to reset it. Then, any DC high-voltage contactor housing to be stamped... The body is fitted onto the outside of the two supports 15 and the electric push rod 110 is activated, which drives the clamping plate 111 to move closer to the corresponding housing. When the clamping plate 111 is in close contact with the corresponding housing, the electric push rod 110 is turned off. Then the stamping equipment can perform wire hole stamping on one end of the corresponding housing. Then the clamping plate 111 is reset a certain distance and the motor 12 is activated. At this time, the motor 12 will drive the rotating plate 13 to rotate 180 degrees, which can rotate the corresponding housing 180 degrees through the two supports 15. Then the housing is limited and fixed by the clamping plate 111 again and the other side is stamped with wire holes. During this period, the stamped waste will fall into the material frame 19 for storage.

[0020] The limiting mechanism 2 includes a crossbar 21, which is slidably inserted into the lower end of one side of the base frame 11. A collar 22 is fixedly sleeved on the crossbar 21. A spring 23 is fixedly installed on one side of the collar 22, and the end of the spring 23 is fixedly connected to the base frame 11. An L-shaped block 24 is fixedly installed at the end of the crossbar 21, and the L-shaped block 24 can be slidably locked on the material frame 19. A lever 25 is integrally formed on one side of the top of the L-shaped block 24, and the outer wall of the lever 25 is covered with an anti-slip texture, which can increase friction and facilitate operation.

[0021] By adopting the above technical solution, when in use, pushing the lever 25 can drive the L-shaped block 24 to move, which in turn can drive the crossbar 21 and the collar 22 to move synchronously and squeeze the spring 23. Then, the material frame 19 is inserted into the inner bottom of the base frame 11 and the lever 25 is released. At this time, the spring 23 will push the collar 22 to reset, which can drive the L-shaped block 24 to reset through the crossbar 21, thereby limiting and fixing the material frame 19 to the inner bottom of the base frame 11.

[0022] Working principle: In use, the base frame 11 is fixed to the DC high voltage contactor stamping equipment with bolts. Then, push the lever 25, which can drive the L-shaped block 24 to move. This can drive the crossbar 21 and the collar 22 to move synchronously and squeeze the spring 23. Then, insert the material frame 19 into the bottom inner side of the base frame 11 and release the lever 25. At this time, the spring 23 will push the collar 22 to reset, which can drive the L-shaped block 24 to reset through the crossbar 21. This can limit and fix the material frame 19 to the bottom inner side of the base frame 11.

[0023] Then, adjust the distance between the two supports 15 according to the actual size of the DC high-voltage contactor housing to be stamped. At this time, turn the top bolt 16, and when the end of the top bolt 16 is separated from the double-ended stud 14, turn one of the handwheels 114 at will. This will drive the double-ended stud 14 to rotate, which in turn will drive the two screw cylinders 117 to move towards or away from each other. This will further drive the two supports 15 to move towards or away from each other. When the distance between the opposite sides of the two supports 15 matches the housing to be stamped, stop turning the handwheel 114 and turn the top bolt 16 in the opposite direction to reset it. Then, fit any DC high-voltage contactor housing to be punched onto the two supports. The electric push rod 110 is activated on the outside of the support frame 15, which drives the clamping plate 111 to move closer to the corresponding housing. When the clamping plate 111 is in close contact with the corresponding housing, the electric push rod 110 is turned off. Then the stamping equipment can perform wire hole stamping on one end of the corresponding housing. Then the clamping plate 111 is reset a certain distance and the motor 12 is started. At this time, the motor 12 will drive the rotating plate 13 to rotate 180 degrees, so that the corresponding housing can be rotated 180 degrees through the two supports 15. Then the housing is fixed and limited by the clamping plate 111 again and the wire hole stamping is performed on the other side. During this period, the stamped waste will fall into the material frame 19 for storage.

[0024] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
