[0033] The following will be combined with the specific implementation of the utility model to clearly and completely describe the technical solution in the utility model. 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 1-5 As shown, a signal distributor for welding tongs of the utility model comprises a fixed seat 1, a movable seat 2, a plug 3 and a limiter 4, which is used for being installed on welding tongs 5 ​​so as to connect the welding tongs 5 ​​with an electrical system and a control system.

[0035] The fixing seat 1 is used to be fixedly arranged on the welding clamp 5 and to support other components.

[0036] The movable seat 2 is used to realize the change of the installation position of the plug 3. A plurality of limiting holes 101 are provided on the fixed seat 1, and the plurality of limiting holes 101 are arranged in a non-collinear manner, that is, the plurality of limiting holes 101 are not arranged in a straight line. A plurality of positioning holes 201 are provided on the movable seat 2. When one positioning hole 201 coincides with one of the limiting holes 101, at least one other positioning hole 201 can coincide with at least two other limiting holes 101, that is, when one positioning hole 201 coincides with one of the limiting holes 101, there is a second positioning hole 201, so that the second positioning hole 201 can coincide with the second limiting hole 101 and the third limiting hole 101. When the second positioning hole 201 coincides with the second limiting hole 101 and the third limiting hole 101, the movable seat 2 can be fixed at different positions and angles of the fixed seat 1.

[0037] The plug 3 is used to conduct with the connecting line. The plug 3 is fixed on the movable seat 2. When the movable seat 2 is fixed at different positions and angles of the fixed seat 1, the plug 3 can be driven to switch to different positions and angles, so that the signal distributor can adapt to different places where the welding clamp 5 is installed.

[0038] In order to facilitate the connection of the plug 3 with the power system and the control system respectively, it is preferred to configure the plug 3 to include two parts, a power connector 31 and a signal connector 32, and both the power connector 31 and the signal connector 32 are fixedly arranged on the movable seat 2; however, when the power connector 31 and the signal connector 32 are installed side by side, interference problems may arise, that is, when the signal connector 32 is connected to the line, it may be blocked by the line already installed on the power connector 31, affecting the wiring convenience of the plug 3. In order to solve this problem, it is preferred to make the fixed position of the signal connector 32 on the movable seat 2 adjustable.

[0039] For the adjustment structure of the signal connector 32 fixed on the movable seat 2, it is preferred to set a set of fixing bolts 33 in the plug 3, open multiple groups of mounting holes 202 on the movable seat 2, set a set of fixing holes 301 on the signal connector 32, so that the fixing holes 301 can overlap with each group of mounting holes 202, and fix the fixing bolts 33 between the fixing holes 301 and one of the groups of mounting holes 202. Figure 4 As shown, the position of the signal connector 32 is adjusted by connecting the fixing bolts 33 and the fixing holes 301 with different groups of mounting holes 202; specifically, in order to ensure the correspondence between the mounting holes 202, the fixing holes 301 and the fixing bolts 33, the number of mounting holes 202 in each group of mounting holes 202 should be the same as the number of fixing holes 301 and the number of fixing bolts 33.

[0040] The limiter 4 is used to fix the movable seat 2 on the fixed seat 1 , and is a specific structure for fixedly connecting the movable seat 2 and the fixed seat 1 . The limiter 4 is fixedly arranged between the overlapping limit hole 101 and the positioning hole 201 .

[0041] The plug 3 will not need to switch angles frequently during actual use, so three limit holes 101 can be provided, and two positioning holes 201 and two limiters 4 can be provided. By utilizing the overlap of the positioning hole 201 with different limit holes 101 and the fixation of the limiter 4 on it, the plug 3 can be switched between several fixed angles.

[0042] Specifically, Figure 2 As shown, the limiting hole 101 is preferably configured to include a fixed limiting hole 1011 and two optional limiting holes 1012, and the spacing from the fixed limiting hole 1011 to the two optional limiting holes 1012 is equal to the spacing between the two positioning holes 201. By using this configuration, the plug 3 can be placed in the Figure 1 and Figure 5 In actual application, when the direction of the plug 3 is perpendicular to the mounting surface of the signal distributor, the wiring operation of the plug 3 can be most convenient. Therefore, it is preferred to make the line connecting the fixed limit hole 1011 and one of the selected limit holes 1012 parallel to the plane of the welding clamp 5 fixing the fixing seat 1, so that the direction of the plug 3 is perpendicular to the line connecting the two positioning holes 201, and the plug 3 is adjusted to Figure 5 When the wiring is completed, adjust the plug 3 to the position shown in the figure. Figure 1 The position shown in the figure should avoid causing bending of the connecting line.

[0043] For convenience, plug 3 in Figure 1 and Figure 5The two states shown are switched, preferably the limiter 4 in the fixed limit hole 1011 is fixedly connected to the fixed limit hole 1011, and the limiter 4 in the fixed limit hole 1011 is rotatably connected to the positioning hole 201 which coincides with the fixed limit hole 1011, that is, when the installation position of the plug 3 is switched, the limiter 4 in the fixed limit hole 1011 does not need to be operated, thus saving the step of the plug 3 state switching operation; correspondingly, the limiter 4 in the selection limit hole 1012 is detachably fixedly connected to the selection limit hole 1012 and the positioning hole 201, and the limiter 4 can be Figure 2 The latch connection structure shown.

[0044] The method of using the signal distributor for welding tongs of the utility model is as follows:

[0045] When it is necessary to adjust the installation angle of the plug 3, first pull out the limiter 4 located in the selection limit hole 1012, then rotate the movable seat 2 to make the positioning hole 201 coincide with another selection limit hole 1012, and then insert the pulled out limiter 4 between the coincident selection limit hole 1012 and the positioning hole 201, so as to realize the switching of the fixed angle of the plug 3; when it is necessary to adjust the position of the signal connector 32, first remove the fixing bolt 33, and then overlap the fixing hole 301 with a group of mounting holes 202 at a suitable position according to actual needs, and then fix the fixing bolt 33 between the coincident fixing hole 301 and the mounting hole 202.

[0046] 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.
