Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of grounding clamp technology, and more specifically, to a sleeve-type welding machine grounding clamp. Background Technology
[0002] An electric welding machine uses the high-temperature electric arc generated when the positive and negative poles are momentarily short-circuited to melt the solder on the welding rod and the material being welded, thus bonding the objects together. Its structure is very simple; it is essentially a high-power transformer. Electric welding machines are generally classified into two types according to the type of output power: AC power and DC power. They utilize the principle of inductance, where the inductance generates a huge voltage change when it is switched on and off. The high-voltage electric arc generated when the positive and negative poles are momentarily short-circuited melts the solder on the welding rod, achieving atomic bonding between them.
[0003] In existing welding machines, when the workpiece needs to be rotated continuously in one direction, the ground wire at the output end of the welding machine rotates along with the workpiece because the ground wire at the output end of the welding machine is fixedly connected to the ground wire clamp. Over time, this can easily cause the ground wire at the output end of the welding machine to break, shortening its lifespan. Chinese Utility Model Publication No. CN207165782U discloses a ground wire clamp for a welding machine, including a wiring mechanism and a clamping mechanism. The clamping mechanism includes a bearing fixedly connected to the wiring mechanism, a connecting component fixed to one side of the bearing, and a clamp fixed to one end of the connecting component. The bearing includes an outer ring fixedly connected to the wiring mechanism and an inner ring fixedly connected to the connecting component. This design solves the problem of the ground wire clamp easily loosening when the workpiece is moved or flipped during operation.
[0004] Although the above technical solution solves the problem that the grounding clamp can rotate with the welded part during use, the fixing effect is limited because the welded part is still held by the grounding clamp alone. There is also the problem that the grounding clamp may fall off the welded part when welding.
[0005] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content
[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide a clamp-type welding machine ground clamp, which solves the technical problem in the related art that the welding parts are still held by ground clamps alone, so the fixing effect is limited and the ground clamps may fall off the welding parts when welding.

[0029] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0035] like Figures 1-4 As shown, a clamp-type welding machine grounding clamp according to an embodiment of the present disclosure is illustrated, comprising:
[0036] A pair of sleeve clamps 1 and a connecting block 2, wherein the sleeve clamps 1 are rotatably connected to the connecting block 2 by a pin;
[0037] Clamping component 3 is mounted on the sleeve 1;
[0038] Anti-detachment component 5 is mounted on connecting block 2;
[0039] Conductive component 4 is disposed outside the connecting block 2;
[0040] The clamping assembly 3 includes a groove 3-1, which is formed in the side surface of the sleeve 1. A pressing block 3-2 is rotatably connected in the groove 3-1 by a pin. A first spring 3-3 is connected between the pressing block 3-2 and the inner surface of the groove 3-1. A pair of second springs 3-4 are connected between the sleeves 1.
[0041] In some examples, a clamping assembly 3 is designed to achieve the clamping effect. A groove 3-1 is provided on the inner side of the sleeve 1. A pressing block 3-2 is rotatably connected to the groove 3-1 through a pin. A first spring 3-3 is connected between the pressing block 3-2 and the groove 3-1, which can make the pressing block 3-2 generate pressure. Two second springs 3-4 are connected between the sleeves 1 to make the sleeves 1 firmly clamp.
[0042] like Figures 1-4 As shown, this embodiment proposes a conductive component 4, which includes a conductive block 4-1. The conductive block 4-1 is fixed on the surface of the connecting block 2. A connecting post 4-2 is provided on the surface of the conductive block 4-1. A circular post 4-3 is fixedly connected to the connecting block 2. A connecting cavity 4-4 is opened in the circular post 4-3. A connecting frame 4-5 is movably connected in the connecting cavity 4-4. A third spring 4-6 is installed on the connecting frame 4-5. A crossbeam 4-7 is provided at the upper end of the connecting frame 4-5. A clamping sleeve 4-8 is provided at the lower end of the crossbeam 4-7. The clamping sleeve 4-8 is installed on the connecting post 4-2. The clamping sleeve 4-8 is made of an insulating material.
[0043] In some examples, to achieve the effect of quickly connecting the ground wire, a conductive component 4 is designed. A conductive block 4-1 and a connecting post 4-2 are provided inside the connecting block 2. A circular post 4-3 is provided on the surface of the connecting block 2 and a connecting cavity 4-4 is opened inside. A connecting frame 4-5 and a third spring 4-6 are movably fitted inside the connecting cavity 4-4, which can make the connecting frame 4-5 telescopic. A cross frame 4-7 and a clamping sleeve 4-8 are provided on the upper end of the connecting frame 4-5. The clamping sleeve 4-8 can be fitted on the connecting post 4-2. The connecting post 4-2 is used to hold the ground wire and is clamped by the elastic force of the clamping sleeve 4-8 and the third spring 4-6.
[0044] like Figures 1-4 As shown, this embodiment proposes an anti-detachment component 5, which includes a circular block 5-1, the circular block 5-1 is fixed on the connecting block 2, and a support frame 5-2 is rotatably connected inside the circular block 5-1, the support frame 5-2 is located between the sleeves 1.
[0045] In some examples, in order to prevent the sleeve 1 from coming loose, an anti-loosening component 5 is designed. A circular block 5-1 is set on the upper end of the connecting block 2 and a support frame 5-2 is rotatably connected inside it, which can support the sleeve 1 and prevent the sleeve from coming loose.
[0046] For example, such as Figure 1As shown, both the surface of the clamping block 3-2 and the side surface of the sleeve 1 have a toothed structure.
[0047] In some examples, a toothed structure is used to increase the anti-slip effect.
[0048] For example, such as Figure 3 As shown, the support frame 5-2 can rotate 90°, and both ends of the support frame 5-2 are inclined structural surfaces.
[0049] In some examples, a 90° rotation angle allows the support frame 5-2 to rotate in only one direction, making it less prone to loosening.
[0050] For example, such as Figure 3 As shown, the inner surface of the sleeve 1 is a semi-circular structure with an arc transition.
[0051] In some examples, the semi-circular structure allows the inner sides of the two clips 1 to form a circle, enabling clamping of various shapes.
[0052] When needed, pull the crossbar 4-7 upward to separate the clamping sleeve 4-8 from the connecting post 4-2, put the ground wire on the connecting post 4-2, then release the crossbar 4-7, press the ground wire with the elastic force of the third spring 4-6, press the sleeve clamp 1 open and grip the grounded metal part, the clamping block 3-2 retracts and is pressed by the elastic force of the first spring 3-3, the conductive block 4-1 contacts the metal part, and finally rotate the support frame 5-2 90° to support it between the sleeve clamp 1.
[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
