Abstract
Description
Technical Field
[0001] This application relates to the technical field of welding apparatus, and in particular to a welding apparatus for electromagnetic valve coil terminals. Background Technology
[0002] Solenoid valves are specialized control devices for pipeline fluids. They are devices that benefit the people and have emerged with the rapid development of electric power technology. A solenoid valve consists of an electromagnetic coil and a valve spool that is driven by the magnetic force generated when the electromagnetic coil is energized. During the operation of the solenoid valve, the electromagnetic coil drives the valve spool to move up and down, which in turn causes the sealing gasket to close the opening inside the flow pipe, thus realizing the automatic opening and closing of the pipeline driven by electricity.
[0003] Traditional solenoid valve coil manufacturing uses tin-immersion soldering or spot welding at both ends of the coil's enameled wire to conduct the enameled wire and form a winding, while using tin to fix the terminals on both sides.
[0004] Regarding the aforementioned technologies, the inventors believe that if non-straight-welded enameled wire is used, the enamel coating of the enameled wire must be removed during the coil winding process, which is cumbersome and inefficient. Utility Model Content
[0005] To improve welding efficiency, this application provides a welding device for electromagnetic valve coil terminals.
[0006] The electromagnetic valve coil terminal welding device provided in this application adopts the following technical solution:

The fixing block is disposed in the middle of the mounting frame and has a mounting groove. Two sets of welding components are provided. Each welding component includes a cylinder and a copper rod. The cylinder is mounted on the mounting frame and its output shaft faces the fixing block. The copper rod is mounted on the output shaft of the cylinder.
[0008] With the above technical solution, during welding, the coil is placed in the mounting slot, the cylinder is started, and the cylinder drives the copper rod to move towards the fixed block. When the copper rod comes into contact with the terminals on both sides of the coil, it conducts electricity. The principle of instantaneous high temperature and high heat generated when high voltage passes through high resistance is used to fuse the coil enameled wire and the copper sheet terminals together, thereby achieving the effect of conductivity and firm reliability, and improving welding efficiency.
[0009] Optionally, it also includes two sets of guide components, which are respectively disposed on both sides inside the mounting frame. Each guide component includes a slide rail and a slider. The slide rail is disposed along the height direction of the mounting frame, and the slider is slidably connected to the slide rail. An extension plate is disposed on the slider, and the extension plate is connected to the cylinder output shaft.
[0010] Through the above technical solution, the slide rail limits the sliding of the slider, thereby guiding the sliding direction of the copper rod, making the sliding of the copper rod more stable, and thus improving the stability of welding.
[0011] Optionally, a nut is threaded onto the cylinder output shaft, the nut abuts against the lower side of the extension plate, and a spring is sleeved on the outer periphery of the cylinder output shaft, one end of the spring abuts against the inner wall of the mounting bracket, and the other end of the spring abuts against the extension plate.
[0012] The above technical solution uses a spring to buffer the downward pressure of the copper rod, reducing the risk of damage to the copper sheet caused by the downward pressure of the copper rod.
[0013] Optionally, the slider sidewall is provided with a connecting rod, the connecting rod is provided with a plug hole for inserting a copper rod, the connecting rod is provided with clamping grooves on both sides of the plug hole, and the connecting rod sidewall is threaded with a fixing screw, the fixing screw passing through the clamping groove.
[0014] With the above technical solution, by designing a clamping groove, when it is necessary to replace the copper rod, the fixing screw can be loosened, and the copper rod can be removed for replacement, which facilitates the replacement of the copper rod.
[0015] Optionally, an insulating plate is provided on the lower side of the mounting bracket, and the fixing block is provided on the upper side of the insulating plate.
[0016] By employing the above technical solutions, the insulating board reduces the risk of electric shock due to leakage during operation, thus improving safety.

Detailed Implementation
[0020] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

The fixing block 1 is located in the middle of the mounting frame 2 and has a mounting groove 11. The welding assembly 3 has two sets. The welding assembly 3 includes a cylinder 31 and a copper rod 32. The cylinder 31 is mounted on the mounting frame 2 and the output shaft of the cylinder 31 is oriented toward the fixing block 1. The copper rod 32 is mounted on the output shaft of the cylinder 31.
[0023] During welding, the coil is placed in the mounting slot 11, and the cylinder 31 is started. The cylinder 31 drives the copper rod 32 to move towards the fixed block 1. When the copper rod 32 comes into contact with the terminals on both sides of the coil, it conducts electricity. The principle of instantaneous high temperature and high heat generated when high voltage passes through high resistance is used to fuse the coil enameled wire and the copper sheet terminal together, thereby achieving the effect of conductivity and firm reliability, and improving welding efficiency.
[0024] It also includes two sets of guide components 4, which are respectively arranged on both sides inside the mounting frame 2. The guide components 4 include a slide rail 41 and a slider 42. The slide rail 41 is arranged along the height direction of the mounting frame 2. The slider 42 is slidably connected to the slide rail 41. An extension plate 421 is provided on the slider 42. The extension plate 421 is connected to the output shaft of the cylinder 31.
[0025] The slide rail 41 limits the sliding of the slider 42, thereby guiding the sliding direction of the copper rod 32, making the sliding of the copper rod 32 more stable, and thus improving the stability of welding.
[0026] A nut 311 is threaded onto the output shaft of cylinder 31. The nut 311 abuts against the lower side of extension plate 421. A spring 312 is sleeved on the outer periphery of the output shaft of cylinder 31. One end of the spring 312 abuts against the inner wall of mounting bracket 2, and the other end of the spring 312 abuts against extension plate 421.
[0027] By setting spring 312, the downward pressure of copper rod 32 is buffered, reducing the risk of damage to copper sheet caused by downward pressure of copper rod 32.

The connecting rod 422 has clamping grooves 4222 on both sides of the insertion hole 4221. The connecting rod 422 has a fixing screw 4223 threadedly connected to its side wall. The fixing screw 4223 passes through the clamping groove 4222.
[0029] When it is necessary to replace the copper rod 32, the fixing screw 4223 can be loosened to remove the copper rod 32 for replacement, which makes the replacement of the copper rod 32 convenient.
[0030] An insulating plate 5 is provided on the lower side of the mounting bracket 2, and a fixing block 1 is provided on the upper side of the insulating plate 5.
[0031] The insulating board 5 reduces the risk of electric shock due to leakage during operation, thus improving safety.

When the copper rod 32 abuts against the terminals on both sides of the coil, the copper rod 32 conducts electricity. The principle of instantaneous high temperature and high heat generated when high voltage passes through high resistance is used to fuse the coil enameled wire and the copper sheet terminal together, thereby achieving the effect of conduction and firm reliability, and improving welding efficiency.
