Description

Technical Field

[0001] This utility model relates to the field of mining parts processing technology, specifically a welding machine for mining parts processing. Background Technology

[0002] The mining industry occupies a significant position in the national economy. It is a foundational and pillar industry of my country's national economy. Although its share of total industrial output is relatively small, the output value of raw material industries and related processing industries based on mining accounts for over 60% of the country's total industrial output. Furthermore, mining is fundamental to many industrial sectors, providing raw materials for numerous others. Specialized mining accessories are essential for mineral development, playing a crucial role in ensuring equipment operation. Mining accessories are core components of coal mine production equipment; their performance and quality directly affect the mine's production efficiency, safety, and equipment lifespan. The production and processing of mining accessories requires welding machines for welding.

[0003] Spot welding equipment is often used in the processing of mining parts. Some spot welding equipment places the parts of the mining parts on a welding table and fixes them. Then, each part to be welded is placed in the welding position. By moving the welding table, the different welding positions are moved to the position of the spot welding head for welding. However, the welding table has a certain inertia when it moves, and the parts to be welded may shake, which may cause the parts to be welded to shift and become unusable for welding. At the same time, since there are many specifications of mining parts, different clamps are required for fixing, which increases the cost. Therefore, we propose a welding machine for the processing of mining parts. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a welding machine for processing mining parts. By moving the spot welding head, the machine avoids the shaking of the parts of the mining parts during welding, and at the same time facilitates the placement and positioning of parts of mining parts with different shapes. This can effectively solve the problems in the background art.

The interior of each hexagonal hole is slidably connected to a hexagonal column. The inner ends of the adjacent hexagonal columns on the left and right are rotatably connected to a rotating plate. The movement of the spot welding head prevents the components of the mining accessories from shaking during welding, and at the same time facilitates the placement and positioning of components of mining accessories with different shapes.

The input end of the two-axis linear guide is electrically connected to the output end of the controller, thereby realizing the positional movement of the welding head plane.

[0012] Furthermore, the spot welding mechanism also includes an electric push rod. Both the upper and lower ends of the support base are fixedly connected to the electric push rod. The telescopic ends of the electric push rod are fixedly connected to the vertically adjacent slides, and the input ends of the electric push rods are electrically connected to the output end of the controller to realize the up and down movement of the spot welding head.

The ranging sensors 36 are bidirectionally electrically connected to the controller 4. The output shaft of the motor 21 drives the bidirectional lead screw 28 to rotate. The two support seats 22 slide relative to each other between the guide rails 27. The distance between the two positioning seats 24 is adjusted to approximate the length of the mining parts. The mining parts are placed between the two positioning seats 24, and the hexagonal column 23 is pushed, causing the rotating plate 26 to contact the mining parts. The contact position... Unlike other methods, the rotating plate 26 rotates and becomes tangent to the contact position. After all the rotating plates 26 are tangent to the contact positions of the parts of the mining accessories, the fixing bolt 25 is rotated by a wrench. The fixing bolt 25 tightens the hexagonal column 23, thereby fixing the position of the rotating plate 26 and setting the placement position of the parts of the mining accessories. During welding, the rotating plate 26 is opened, and the parts of the mining accessories are placed between the two positioning seats 24. The parts of the mining accessories are snapped between the rotating plates 26. Then, the parts of the mining accessories that need to be welded are placed at the welding position.

The upper surface of the welding table 1 has symmetrically distributed and slidable support bases 22 on its front side.

[0025] The working principle of the welding machine for processing mining parts provided by this utility model is as follows: The output shaft of the motor 21 drives the bidirectional lead screw 28 to rotate. The two support seats 22 slide relative to each other between the guide rails 27. The distance between the two positioning seats 24 is adjusted to be close to the length of the mining parts. The mining parts are placed between the two positioning seats 24, and the hexagonal column 23 is pushed respectively. The rotating plate 26 contacts the mining parts. Depending on the contact position, the rotating plate 26 rotates and becomes tangent to the contact position. After all the rotating plates 26 are tangent to the contact position of the mining parts, the fixing bolt 25 is rotated by a wrench. The fixing bolt 25 tightens the hexagonal column 23, realizing the positioning of the rotating plate 26. The positioning is fixed to complete the placement of the mining accessories components.
