Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to an automatic clamping device used for automatically replacing a conductive nozzle. Background Art

[0002] In the production process of thick plate welding products, welding operations need to be performed on parts or parts, and robots are generally used to operate welding guns for welding. After the welding gun has been working for a period of time, the conductive nozzle and the nozzle will wear out, which directly affects the welding quality. The welding quality affects the company's benefits. Therefore, the best way is to replace the conductive nozzle after the welding gun has been working for a period of time.

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0016] Reference Figure 1 , an automatic clamping device for automatically replacing a conductive nozzle device, comprising a nozzle disassembly base 1, mounting blocks are fixedly connected to the outer wall of the nozzle disassembly base 1 on both sides symmetrically, and fixed pins 7 are rotatably installed on both sides of the outer wall of the nozzle disassembly base 1 through the mounting blocks, nozzle pressing sleeves 6 are fixedly sleeved on the outer sides of the two fixed pins 7, and the two nozzle pressing sleeves 6 are symmetrically arranged along the center line of the nozzle disassembly base 1, shaft sleeves 2 are installed at both ends of the fixed pins 7, a nozzle pressing head 3 is fixedly connected to the inclined surface above the nozzle pressing sleeve 6, a nozzle fixing mold 5 is slidably connected to the inner side of the nozzle disassembly base 1, a spring 8 is installed between the nozzle fixing mold 5 and the inner bottom surface of the nozzle disassembly base 1, connecting rods 4 are rotatably installed on both sides of the top of the nozzle fixing mold 5 through pins 9, the top of the connecting rod 4 is rotatably connected to the nozzle pressing sleeve 6 through the pin 9, and a nozzle 10 is arranged above the middle of the nozzle disassembly base 1;

[0017] The technical solution adopted above uses an external manipulator to drive the nozzle 10 to move downward and insert it into the nozzle removal base 1. The nozzle 10 abuts against the nozzle fixing mold 5 and drives it to move downward, and the spring 8 is compressed at this time. When the nozzle fixing mold 5 moves downward, it will pull the lower side of the nozzle pressing sleeve 6 through the connecting rod 4, so that the nozzle pressing sleeve 6 rotates around the fixed pin shaft 7 on the other side below it, and the nozzle pressing head 3 moves in an arc toward the nozzle 10 until the end of the nozzle pressing head 3 abuts against the outer wall of the nozzle 10, thereby clamping and fixing the nozzle 10 through the nozzle pressing heads 3 on both sides, so that the nozzle 10 can be rotated and removed by mechanical tools.

[0018] A notch is formed at the top of the nozzle fixing mold 5, and the bottom end of the nozzle 10 is inserted into the inner side of the notch;

[0019] In the technical solution adopted above, the design of the notch facilitates the positioning of the nozzle 10, so that the bottom end of the nozzle 10 is inserted into the notch and drives the nozzle fixing mold 5 to move downward.

[0020] The end surface of the nozzle pressure head 3 and the two outer sides of the nozzle 10 are provided with matching tooth patterns;

[0021] In the technical solution adopted above, the arrangement of the tooth pattern can increase the friction between the nozzle pressure head 3 and the outer wall of the nozzle 10, thereby improving the stability of the clamping.

[0022] Both sides of the top of the nozzle disassembly base 1 are provided with notches for the nozzle pressing sleeve 6 to move;

[0023] In the technical solution adopted above, the notch is provided to facilitate the nozzle pressing sleeve 6 to have corresponding movable space when it is acted upon by the connecting rod 4 .

[0024] Working principle:

[0025] The manipulator reaches the specified position and drives the nozzle 10 to move downward. The nozzle 10 moves downward after contacting the nozzle pressing sleeve 6. The nozzle fixing mold 5 is pin-connected to the connecting rod 4 with the pin shaft 9. The connecting rod 4 is pin-connected to the nozzle pressing sleeve 6 with the pin shaft 9. At the same time, the fixing pin shaft 7 sets the other end of the nozzle pressing sleeve 6 at the nozzle disassembly base 1, so that after the nozzle 10 moves downward, the nozzle pressing head 3 connected to the nozzle pressing sleeve 6 can move inward. The contact between the nozzle pressing head 3 and the nozzle 10 is designed with special matching teeth, which changes the line-surface contact between the two into surface-to-surface contact, thereby increasing the friction force to clamp the nozzle 10. A spring 8 is placed between the nozzle fixing mold 5 and the nozzle disassembly base 1 to provide elastic force when the manipulator leaves, so that the entire device can return to its original state and wait for the next work, thereby achieving the effect of automatic clamping.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
