Description

Technical Field

[0001] The present application relates to the technical field of electric welding machines, and in particular to a spot welding device. Background Art

[0002] The blade of a lawn mower can be regarded as a single layer of metal sheet. Operators usually weld a layer of gasket at the end of one side of the blade to increase the force-bearing area on the side of the lawn mower blade, thereby achieving the effect of improving the stability of the blade during mowing operations.

[0003] The existing method of welding the blade and the gasket mainly uses a manually operated welding gun for manual welding. However, manual operation requires a high level of technical skills of the operator, and there are also disadvantages such as fatigue of the operator who manually controls the welding gun, which easily causes the spot welding position to shift, resulting in low welding accuracy, which has a certain impact on the subsequent installation process of the blade. Utility Model Content

[0004] In order to improve the situation where the spot welding position is offset and enhance the welding accuracy, the present application provides a spot welding device.

[0005] The spot welding equipment provided in this application adopts the following technical solution:

[0007] By adopting the above technical solution, the welding gun is used for welding operation, and the first driving member can drive the welding gun so that the relative position between one end of the welding gun used for welding operation and the gasket on the welding platform can be controlled. The welding platform provides an operating platform for the welding operation between the blade member and the gasket, and the positioning block is arranged on the welding platform so that the blade member and the gasket can be clamped and placed, thereby improving the stability during the welding operation, thereby improving the situation where the spot welding position is offset and improving the welding accuracy.

[0008] Optionally, a telescopic arm is fixedly connected to a side of the welding platform close to the machine body, and the telescopic arm is slidably installed on the side wall of the machine body away from the side connected to the welding platform and drives the welding platform to approach or move away from the machine body.

[0009] By adopting the above technical solution, the setting of the telescopic arm enables the relative position between the welding platform and the machine body to be adjusted, the welding gun moves up and down due to the trend of the first driving member, and the welding platform moves horizontally due to the trend of the telescopic arm, so that the welding point on the gasket can be aligned with the end of the welding gun, thereby improving the stability during the welding operation, thereby improving the deviation of the spot welding position and improving the welding accuracy.

[0010] Optionally, a clamping mechanism is provided on the welding platform, and the clamping mechanism is symmetrically arranged on both sides of the welding platform to press the gasket and the blade member onto the positioning block.

[0011] By adopting the above technical solution, the clamping mechanism is arranged on both sides of the welding platform, so that the gasket and the blade can be clamped and fixed from both sides, which is equivalent to locking the welding point position, thereby improving the stability during the welding operation, thereby improving the deviation of the spot welding position and improving the welding accuracy.

[0012] Optionally, the clamping mechanism includes a clamping block, a second driving member for driving the clamping block, and a support rod, the second driving member is arranged on a side of the welding platform away from the welding gun, the driving end of the second driving member is passed through and slides on the welding platform, the clamping block is fixedly connected to the end of the second driving member, and the end of the clamping block away from the end connected to the second driving member is pressed on a gasket, and mounting seats for installing the support rod are symmetrically arranged on both sides of the welding platform, the support rod is fixedly connected between the two mounting seats, and the side walls of the clamping block abut against the support rod.

[0013] By adopting the above technical solution, the second driving member is used to drive the clamping block, and the support rod provides a fulcrum for the clamping block, which plays a role in changing the direction of force. When the second driving member is pushed up by one end of the clamping block, the direction of force of the clamping block changes with the support rod as the axis, so that the clamping block is moved away from one end of the second driving member and pressed on the gasket, and the gasket and the blade member are fixed on the positioning block, thereby improving the stability during welding operation, thereby improving the situation where the spot welding position is offset and improving the welding accuracy.

[0020] Optionally, a sliding block is provided on a side of the support plate away from the support frame, and a sliding groove for the sliding block to be inserted into and slide is provided on the raised platform.

[0024] Optionally, the clamping block is provided with an adjustment hole for adjusting the relative position of the welding gun and the gasket.

[0025] By adopting the above technical solution, the opening of the adjustment hole can adjust the relative position between the end of the welding gun and the gasket, which is beneficial to fix the welding point position, improve the deviation of the spot welding position, and improve the welding accuracy.

When the second driving member 52 is pushed upward by one end of the clamping block 51, the force direction of the clamping block 51 changes with the support rod 53 and the gasket tube 532 as the axis, so that the end of the clamping block 51 away from the second driving member 52 is pressed against the gasket.
