[0005] The wrench includes a socket head and a multifunctional handle, one end of the multifunctional handle is fixedly mounted with a tooth end, the other end of the multifunctional handle is fixedly mounted with a hammer end, the tooth end is connected to the socket head by a connecting screw, and a stepped hole is opened on the socket head;

[0006] The wrench balancing rod includes a balancing chuck, a balancing handle is fixedly installed on one side of the balancing chuck, a connecting hole is opened on the balancing chuck, and the connecting hole is used to connect a fixing screw. A clamping block is also provided on one side of the balancing chuck, and the clamping block is movably connected to the balancing chuck through an adjusting screw.

[0007] Preferably, one end of the tooth end is integrally formed with fine teeth.

[0008] Preferably, the stepped hole consists of two parts, the lower half is a circular hole for inserting the welding head, and the upper half is a threaded hole for fixing the fixing screw on the wrench balance rod.

[0009] Preferably, notches are provided inside the sleeve head and inside the balancing chuck for respectively fitting the tooth end and the sleeve head.

[0010] Preferably, two threaded holes adapted to the adjusting screws are respectively provided inside the balancing chuck and inside the clamping block.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Refer to the following Figures 1-4 A multifunctional wrench for tightening the welding head of a resistance welding machine provided in one embodiment of the present application will be described.

[0024] A multifunctional wrench for tightening and loosening the welding head of a resistance welding machine, such as Figure 1 As shown, it includes a wrench 1 and a wrench balancing rod 2, which are fixed by a fixing screw 3. The fixing screw 3 also facilitates adjusting the position of the wrench 1 during use;

[0025] like Figure 2 As shown, the wrench 1 includes a socket head 101 and a multifunctional handle 102. A tooth end 105 is fixedly mounted on one end of the multifunctional handle 102, and a hammer end 103 is fixedly mounted on the other end of the multifunctional handle 102. During operation, if the welding joint is too tight and needs to be slightly struck, the hammer on the hammer end 103 on the wrench 1 can be used to strike it, which can reduce the time of searching for tools and increase torque during operation, thereby improving work efficiency. The tooth end 105 is connected to the socket head 101 by a connecting screw 106, and a stepped hole 104 is opened on the socket head 101;

[0026] like Figure 3 As shown, the wrench balancing rod 2 includes a balancing chuck 201, a balancing handle 202 is fixedly installed on one side of the balancing chuck 201, a connecting hole 203 is opened on the balancing chuck 201, and the connecting hole 203 is used to connect the fixing screw 3. A clamping block 204 is also provided on one side of the balancing chuck 201, and the clamping block 204 is movably connected to the balancing chuck 201 through an adjusting screw 205. By setting the wrench balancing rod 2, the rotational force balance can be ensured, and it is convenient to clamp the flat mouth position on the resistance welding machine.

[0027] Further, such as Figure 4 As shown, one end of the tooth end 105 is integrally formed with fine teeth 107. The fine teeth 107 of the tooth end 105 increase the friction force, which can stabilize the circular welding gun head and ensure that the teeth will not damage the welding gun head. The teeth are processed in both directions and can be used in both directions to loosen or tighten the welding head.

[0028] Furthermore, the stepped hole 104 is composed of two parts. The circular hole in the lower part is used to insert the welding head, and the upper part is a threaded hole used to fix the fixing screw 3 on the wrench balance rod 2.

[0029] Furthermore, notches are provided in the interior of the sleeve head 101 and the interior of the balancing chuck 201 for respectively fitting the tooth end 105 and the sleeve head 101 .

[0030] In a further embodiment, two threaded holes compatible with the adjusting screw 205 are respectively provided inside the balancing chuck 201 and the clamping block 204. The position of the clamping block 204 can be adjusted by rotating the adjusting screw 205, so that the clamping block 204 can clamp the flat mouth position of the resistance welding machine.

[0031] In combination with the above embodiments, the specific working process of a multifunctional wrench for tightening the welding head of a resistance welding machine of the present application is described: when working, the wrench 1 and the wrench balance bar 2 are fixed with a fixing screw 3, and the position of the clamping block 204 can be adjusted by rotating the adjusting screw 205. The clamping block 204 on the wrench balance bar 2 clamps the flat mouth position of the resistance welding machine, and the circular hole part of the stepped hole 104 on the socket head 101 is covered on the welding head. The position of the wrench 1 can be controlled by adjusting the fixing screw 3, and the tooth end 105 of the multifunctional handle 102 is used to clamp the welding head. The fine teeth 107 are in contact with the welding head. The welding head is tightened or loosened as needed. During operation, if the welding head is too tight and needs to be hit lightly, it can be hit with the hammer on the hammer end 103 on the wrench 1.

[0032] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
