Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] like Figure 1-4 As shown, a transformer installation structure of a welding clamp of the utility model comprises a welding clamp body 1, a basic transformer 2, a side plate 3, a current regulating transformer 4 and two conduction plates 5.

[0035] The welding clamp body 1 is the main structure of the welding clamp, including two welding guns and related fixed support structures.

[0036] The basic transformer 2 is used to provide current for the welding gun, and the basic transformer 2 is fixedly arranged on the welding clamp body 1 .

[0037] The side plate 3 is used to carry the current regulating transformer 4 , and the side plate 3 is slidably arranged on the welding clamp body 1 .

[0038] The current regulating transformer 4 is used to cooperate with the basic transformer 2 to provide current for the welding gun, and the current regulating transformer 4 is fixedly arranged on the side plate 3.

[0039] The conducting plate 5 is used to connect the positive and negative electrodes of the basic transformer 2 in parallel with the positive and negative electrodes of the current regulating transformer 4, and to conduct with the two welding guns. The two conducting plates 5 are fixedly arranged between the basic transformer 2 and the current regulating transformer 4 in a detachable manner, that is, the conducting plate 5 is detachably fixedly connected to the basic transformer 2 and the current regulating transformer 4. Figure 1 As shown, since the side plate 3 and the welding clamp body 1 are slidably connected, when the connection between the conduction plate 5 and the current regulating transformer 4 is released, the side plate 3 and the current regulating transformer 4 can be slid off the welding clamp body 1, so as to facilitate the replacement of different types of current regulating transformers 4, and the current regulating transformer 4 that meets the parameter requirements is connected in parallel with the basic transformer 2 to provide a suitable current for the welding clamp; the basic transformer 2 can use a transformer with the smallest parameters among commonly used models, so that when the current regulating transformer 4 is not used, the basic transformer 2 provides the minimum current, and after using different types of current regulating transformers 4, the welding current is increased to adapt to actual processing needs.

[0040] With respect to the sliding connection between the side plate 3 and the welding clamp body 1, it is preferred that the welding clamp body 1 includes a fixed bracket 11 and a first sliding portion 12, the basic transformer 2 is fixedly arranged on the fixed bracket 11, and the first sliding portion 12 is arranged on the fixed bracket 11; the side plate 3 includes a plate body 31 and a second sliding portion 32, the second sliding portion 32 is arranged on the plate body 31, and the plate body 31 and the fixed bracket 11 are connected through the sliding fit of the first sliding portion 12 and the second sliding portion 32; specifically, as Figure 3 As shown, the first sliding part 12 can be set to a round rod-shaped structure and fixedly connected to the fixed bracket 11, and the second sliding part 32 can be set to a round hole-shaped structure and opened on the plate body 31, so that the outer diameter of the first sliding part 12 is equal to the inner diameter of the second sliding part 32, so as to realize the sliding of the first sliding part 12 and the second sliding part 32, thereby realizing the sliding connection between the side plate 3 and the welding clamp body 1.

[0041] As a preferred embodiment, the fixed bracket 11 includes a support frame 111, an upper fixed plate 112 and a lower fixed plate 113, wherein the upper fixed plate 112 and the lower fixed plate 113 are both fixedly arranged on the support frame 111, and the upper fixed plate 112 and the lower fixed plate 113 are both provided with a first sliding portion 12, and the upper fixed plate 112 and the lower fixed plate 113 are both slidably connected to the plate body 31, so that the basic transformer 2 is located between the upper fixed plate 112 and the lower fixed plate 113, and is fixedly connected to the two. This method strengthens the fixing firmness of the basic transformer 2 and prevents it from vibrating during use; similarly, in order to improve the fixing firmness of the current regulating transformer 4, the upper fixed plate 112 and the lower fixed plate 113 can be arranged in parallel, and the current regulating transformer 4 can be slidably connected to the upper fixed plate 112 and the lower fixed plate 113, and the upper fixed plate 112 and the lower fixed plate 113 are used to support both sides of the current regulating transformer 4 to prevent it from vibrating.

[0042] In order to realize the detachable connection between the conducting plate 5 and the basic transformer 2 and the current regulating transformer 4, the conducting plate 5 should be fixedly connected with the basic transformer 2 and the current regulating transformer 4 by bolts respectively; Figure 1 As shown, it is preferred that the current regulating transformer 4 and the side panel 3 are also fixedly connected by bolts. When the fixing bolts between the current regulating transformer 4 and the conductive plate 5 and the side panel 3 are contacted, the current regulating transformer 4 can be pulled out to the right. This disassembly method is suitable for the working condition where the side panel 3 is blocked and inconvenient to disassemble.

[0043] The axial direction of the bolts between the conducting plate 5 and the current regulating transformer 4 is preferably perpendicular to the axial direction of the first sliding part 12, that is, the sliding direction of the side plate 3 is perpendicular to the fixing direction of the bolts on the conducting plate 5, thereby improving the limiting effect of the bolts and the first sliding part 12 on the side plate 3 and the current regulating transformer 4 to prevent them from shaking; in order to enhance this limiting effect, it is preferred to set both the first sliding part 12 and the second sliding part 32 to be several.

[0044] In order to improve the fixing degree between the current regulating transformer 4 and the side plate 3 , a slot 301 may be provided on a side of the side plate 3 close to the current regulating transformer 4 , and the current regulating transformer 4 may be clamped in the slot 301 .

[0045] The method of using the transformer installation structure of a welding clamp of the utility model is as follows:

[0046] When the current regulating transformer 4 needs to be replaced, the current regulating transformer 4 can be replaced by first unscrewing the bolts between the current regulating transformer 4 and the conduction plate 5, and then sliding the side plate 3 off the welding clamp body 1. The current regulating transformer 4 can also be replaced by first unscrewing the bolts between the current regulating transformer 4 and the conduction plate 5, and then unscrewing the bolts between the side plate 3 and the current regulating transformer 4, and finally pulling the current regulating transformer 4 out of the cavity formed by the upper fixing plate 112, the lower fixing plate 113 and the side plate 3. After replacing the current regulating transformer 4 with a suitable model, the above steps can be reversed to install the current regulating transformer 4.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
