[0002] With the continuous development of the manufacturing industry, non-standard welding, as a flexible and efficient connection method, has been widely used in various fields; a varistor is a voltage-limiting protection device. Utilizing the non-linear characteristics of the varistor, when an overvoltage appears between the two poles of the varistor, the varistor can clamp the voltage to a relatively fixed voltage value, thereby realizing the protection of the subsequent circuit; when the existing welding mechanism for varistor processing is used, first place the varistor on the top of the operating table, then start the welding machine, and the operator holds the welding torch and welds the varistor.

[0003] However, when the welding mechanism for varistor processing is used, the varistor is generally directly placed in the working area and is slightly supported by hand for fixation during welding, resulting in the varistor being prone to deviation during welding, thereby affecting the welding quality and causing inconvenience to the staff. For this reason, we propose a welding mechanism for varistor processing. Content of the Utility Model

[0006] Among them, a collection box is placed at the bottom inside the working frame and located at the bottom of the processing and positioning component, and the welding torch is electrically connected to the welding machine device.

[0007] Among them, the processing and positioning component includes a connecting seat arranged inside the working frame, two symmetrically arranged fixing seats are installed on the top of the connecting seat, and an installation rod and a spring are installed inside both fixing seats, and the spring is located outside the installation rod.

[0008] Among them, two symmetrically arranged sliding seats are sleeved outside both installation rods, one end of the spring is connected to the sliding seat, and a positioning plate is fixedly installed on one side of both sliding seats.

[0009] Among them, handles are fixedly installed at the top and bottom of the two positioning plates, and several groups of anti-slip particles at equal distances are arranged on one side of the two positioning plates.

[0010] Among them, the anti-slip particles are made of rubber, and a through groove is opened inside the connecting seat at the position corresponding to the handle at the bottom of the positioning plate.

[0011] Among them, fixing cylinders are installed on both outer sides of the connecting seat, and a rotating shaft is installed inside the fixing cylinder.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Example 1

[0021] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a welding mechanism for processing varistors, including a working frame 1, an internal connection of the working frame 1 is provided with a processing and positioning component 2, the outer side of the top of the working frame 1 is installed with a support frame 3, the inner side of the support frame 3 is installed with a motor 4, the inner part of the working frame 1 and at the bottom of the processing and positioning component 2 is placed a collection box 5, the outer side of the bottom of the working frame 1 is provided with a welding machine device 6, the outer side of the welding machine device 6 is provided with an elastic clamping seat 7, the top of the elastic clamping seat 7 is provided with a welding torch 8, and the welding torch 8 is electrically connected to the welding machine device 6.

[0022] The processing and positioning component 2 includes a connecting seat 21 arranged inside the working frame 1, the top of the connecting seat 21 is installed with two symmetrically arranged fixing seats 22, the inner parts of the two fixing seats 22 are both installed with mounting rods 23 and springs 24, the springs 24 are located outside the mounting rods 23, the outer parts of the two mounting rods 23 are both sleeved with two symmetrically arranged sliding seats 25, one end of the spring 24 is connected to the sliding seat 25, one side of each of the two sliding seats 25 is fixedly installed with a positioning plate 26, the top and bottom of the two positioning plates 26 are both fixedly installed with handles 27, several groups of equidistant anti-slip particles 28 are arranged on one side of the two positioning plates 26, the anti-slip particles 28 are made of rubber material, through grooves 29 are opened inside the connecting seat 21 at positions corresponding to the handles 27 at the bottom of the positioning plates 26, and fixing cylinders 210 are installed on both outer sides of the connecting seat 21, and rotating shafts 211 are installed inside the fixing cylinders 210.

[0023] When processing and welding the varistor, the user fixes the varistor through the processing and positioning component 2. The user first holds and pulls the handle 27 installed at the top of one positioning plate 26. At this time, the sliding seats 25 installed at both ends of the positioning plate 26 slide inside the two fixing seats 22. The sliding seats 25 slide outside the mounting rods 23 and squeeze the springs 24. After expanding the distance between the two positioning plates 26, the user places the varistor between the two positioning plates 26, and then releases the handle 27. Through the setting of the springs 24, the sliding seats 25 bounce back to their original positions, and the sliding seats 25 drive the positioning plates 26 to reset. The two positioning plates 26 can then clamp and fix the varistor. The arranged anti-slip particles 28 can increase the clamping effect. After the varistor is clamped and positioned, the user performs the welding work on the varistor through the welding machine device 6 and the welding torch 8, and the welding torch 8 is fixed through the elastic clamping seat 7.

[0024] Example 2

[0025] As Figures 1 to 4, in the second embodiment, other structures remain unchanged. Different from the first embodiment, the power driving end of the motor 4 is connected to one of the rotating shafts 211, and the other rotating shaft 211 is rotatably connected inside the working frame 1. After the varistor welding is completed, the user starts the motor 4. When the power driving end of the motor 4 drives the rotating shaft 211 to rotate, at this time, the connecting seat 21 rotates inside the working frame 1, and the motor 4 drives the connecting seat 21 to flip 180 degrees. When the varistor faces the collecting box 5, the user holds the handle 27 at the through groove 29 and pulls the positioning plate 26 to increase the distance between the two positioning plates 26. At this time, the varistor drops downward into the collecting box 5; this structure does not require the user to remove it after the welding cools, improving the welding efficiency.
