DETAILED DESCRIPTION

[0030] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0031] In the present disclosure, unless otherwise specified, directional words such as "inner" and "outer" are defined with respect to the outline of the corresponding component. The use of the terms "first", "second", etc. is intended to distinguish different components and does not have order and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements.

[0032] According to one embodiment of the present disclosure, Figures 1 to 4 As shown, a wire fixing tool is provided, which can be used to fix the wire to be welded, and the wire fixing tool includes two positioning blocks 1, a support 2, a pressure plate 3 and a connecting portion 4. Among them, the two positioning blocks 1 can be used to connect with external equipment respectively, and the opposite sides of the support 2 are respectively provided with first grooves 21 for accommodating the positioning blocks 1, so that the positioning blocks 1 can clamp the support 2, and the first groove 21 is detachably connected to the positioning blocks 1. The pressure plate 3 can be used to limit the wire between the pressure plate 3 and the external equipment, that is, to press the wire, and the pressure plate 3 can be movably connected to the support 2 through the connecting portion 4, and the connecting portion 4 can provide a force that presses the pressure plate 3 against the wire. The external equipment here can refer to welding equipment or other auxiliary tooling for welding the wire, wherein the welding equipment can also include its working platform and welding manipulator, which is not limited in the present disclosure.

[0033] Through the above technical solution, the positioning block 1 is connected to the external device, and the two positioning blocks 1 cooperate with the first groove 21 of the support 2, so that the two positioning blocks 1 can clamp the support 2 so that the wire fixing tool can be stably fixed on the external device. At the same time, the pressing plate 3 connected to the support 2 can press and fix the wire to be welded on the external device to prevent the wire from moving, which can effectively reduce the probability of false welding of the wire during the welding process and the deviation of the welding position and angle, reduce rework and waste, and effectively improve the accuracy and efficiency of wire welding.

[0034] Furthermore, if Figure 3 As shown, a second groove 211 may also be provided on the bottom wall of the first groove 21, and an elastic member 5 is accommodated in the second groove 211. The elastic member 5 can abut against the positioning block 1, and can provide a force to keep the positioning block 1 away from the bottom wall of the first groove 21. It should be noted that the bottom wall here refers to the wall at the deepest position along the concave direction of the first groove 21. The elastic member 5 can abut against the two positioning blocks 1 on both sides in two opposite directions, so that the clamping between the positioning block 1 and the support 2 is relatively balanced and not prone to movement. The elastic member 5 can be an elastic rubber or a spring, and the present disclosure does not limit this.

[0035] According to one embodiment of the present disclosure, Figures 1 to 3 As shown, the positioning block 1 may be provided with a first positioning hole 11 that passes through the positioning block 1, and the two sides of the first groove 21 may be provided with second positioning holes 212 that correspond to the first positioning hole 11, respectively. The wire fixing tool also includes a first fixing member, and the first fixing member passes through the first positioning hole 11 and the second positioning hole 212. In this way, after the positioning block 1 is inserted into the first groove 21, when the first positioning hole 11 and the second positioning hole 212 are aligned, the two can be simultaneously penetrated by fasteners such as positioning pins or screws and studs. The fasteners can sequentially pass through a first positioning hole 11, the second positioning hole 212, and another first positioning hole 11 that is arranged opposite to the first first positioning hole 11, thereby completing the installation of the positioning block 1 and the first groove 21, and preventing the positioning block 1 from being separated from the first groove 21.

[0036] Furthermore, if Figures 1 to 3 As shown, the first positioning hole 11 may be a strip hole, and the second positioning hole 212 may be a circular hole. In this way, when the positioning block 1 is installed between the first groove 21, the support 2 may slide along the extension direction of the strip hole to a certain extent, thereby increasing the matching range of the first positioning hole 11 and the second positioning hole 212, and preventing the problem of being unable to be installed and fixed due to the space restriction of the external device causing the two positioning blocks 1 to be too close or too far apart, so that the first positioning hole 11 and the second positioning hole 212 cannot be completely matched when the two positioning blocks 1 are fixed on the external device respectively.

[0037] According to one embodiment of the present disclosure, Figures 1 to 4 As shown, the pressing plate 3 may include a wire pressing portion 31 and an avoidance portion 32. The wire pressing portion 31 may be used to press the wire tightly to prevent the wire from running around and causing an unsatisfactory welding effect. One end of the avoidance portion 32 may be connected to the connecting portion 4, and the other end may be connected to the side of the wire pressing portion 31 away from the wire. Due to structural problems of the external device, a side of the avoidance portion 32 close to the wire may be provided with an avoidance groove 321 for avoiding the external device to avoid collision and interception with the external device due to structural problems, which may cause an unsatisfactory wire pressing effect of the wire pressing portion 31.

[0038] Furthermore, if Figure 3 As shown, a third groove 311 for accommodating the wire can be provided on one side of the wire pressing portion 31 close to the wire, so that when the wire pressing portion 31 presses the wire onto the external device, the wire can be located in the third groove 311, thereby limiting the range of movement of the wire and preventing the wire from wandering around, so as to improve welding accuracy. The third groove 311 can be a straight groove, and an arc groove, a wavy groove, and a folded groove are also within the protection scope of the present disclosure.

[0039] Furthermore, if Figure 3 As shown, the third groove 311 may be two spaced apart, and a fourth groove 312 is provided between the two third grooves 311, and the fourth groove 312 and the third groove 311 are arranged in a stepped manner. That is, the bottom wall of the fourth groove 312 is farther away from the wire than the bottom wall of the third groove 311. The wires to be welded have different lengths. When the wires are accommodated in the third groove 311 and the fourth groove 312, the third groove 311 can limit the wires from both ends, so that the fourth groove 312 in the middle can allow a certain degree of wire redundancy, and the redundant part of the wire can be accommodated in the fourth groove 312.

[0040] According to one embodiment of the present disclosure, Figures 1 to 4 As shown, the connecting part 4 may include a pin 41 and a torsion spring 42. The pin 41 may be fixedly connected to the support 2, and the pressure plate 3 may be rotatably sleeved on the pin 41. The torsion spring 42 is sleeved on the pin 41 and in contact with the pressure plate 3, and can provide a force that presses the pressure plate 3 against the wire. When the wire needs to be placed between the pressure plate 3 and the external device for fixed compression, the pressure plate 3 is moved at this time, and the wire is placed in the gap between the pressure plate 3 and the external device, and the pressure plate 3 is released. At this time, under the action of the torsion spring 42, the pressure plate 3 rotates in the direction of the wire to achieve an automatic compression effect. When the wire welding is completed, the pressure plate 3 is moved at this time to create a gap between the pressure plate 3 and the external device, and the wire can be taken out, and then the pressure plate 3 can be released.

[0041] Furthermore, if Figure 1 and Figure 2As shown, the support 2 may be provided with a fixing groove 22, and the pin 41 may be at least partially accommodated in the fixing groove 22, so that the structure of the wire fixing tool is more compact and the space occupied is reduced. The pin 41 may also be fixed in the fixing groove 22 by fasteners such as screws, studs or positioning pins, which is not limited in the present disclosure.

[0042] According to one embodiment of the present disclosure, Figures 1 to 3 As shown, a weight-reducing groove 23 may be provided on the support 2, and the weight-reducing groove 23 is located between the two first grooves 21. The weight-reducing groove 23 may be a U-shaped groove, which can reduce the material of the support 2 and reduce the manufacturing cost without affecting the function of the fixing tool.

[0043] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0044] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0045] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
