Description

Technical Field

[0001] This utility model relates to the field of spot welding machine technology, specifically a spot welding machine with protective functions. Background Technology

[0002] Spot welding machines are mechanical devices that use resistance heating to join metals. They achieve rapid welding by generating high temperatures and applying pressure at the contact points of workpieces through current. They are widely used in automobile manufacturing, electronics industry and other fields.

[0003] For example, the Chinese authorized patent (automatic spot welding machine) with announcement number CN102079007B includes a spot welding machine body with a vertical guide rail, and upper and lower electrode seats are movably fixed to the vertical guide rail. A slide is fixedly mounted on the spot welding machine body, and a horizontal guide rail is mounted on the upper surface of the slide. A servo motor is mounted at one end of the slide. A work platform is movably mounted on the horizontal guide rail. An adjustable stroke cylinder and a fixture for accommodating the weldment are fixedly mounted on the work platform. One end of the adjustable stroke cylinder is connected to the fixture. The work platform is located between the upper and lower electrodes. A solenoid valve is fixedly mounted on the base of the spot welding machine body. The solenoid valve is connected to one end of the adjustable stroke cylinder through a wire and is also connected to a power supply. A controller is provided and connected to the servo motor. This structure makes the spot welding machine an automatically controlled system. From loading the fixture to completing the spot welding, no extra manual operation is required, which improves work efficiency and reduces manpower and safety factors.

[0004] However, existing spot welding machines lack protection at the spot welding position, making it easy for objects to fall and be damaged when they are placed and picked up during spot welding, resulting in low safety. Therefore, they do not meet the current needs, and we have proposed a spot welding machine with protective functions. Utility Model Content

The rear surface of the protective baffle is provided with an installation notch, and the object fixing seat and the connecting base plate are inserted into the installation notch.

[0008] Preferably, both ends of the installation notch are provided with fence panels, and a storage cavity is formed between the fence panels and the protective baffle, and multiple storage cavities are provided.

[0009] Preferably, the lower surfaces of both ends of the protective baffle are provided with limit plates, and the upper surfaces of both ends of the protective base plate are provided with limit slots, with the limit plates inserted into the limit slots.

[0010] Preferably, the upper surface of the protective base plate near the rear end is provided with limit holes, and there are multiple limit holes; the lower surface of the connecting base plate is provided with limit posts, and there are multiple limit posts, and the limit posts are inserted into the limit holes.

[0011] Preferably, the lower end of the protective base plate is provided with a fixing bolt, the lower surface of the connecting base plate is provided with a bolt hole, and one end of the fixing bolt passes through the protective base plate and is threadedly connected to the bolt hole.

[0012] Preferably, a cylinder is provided at the upper end of the top seat, and the output end of the cylinder drives the spot welding head to move up and down.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model sets a protective component on the outside of the object fixing seat. During installation, the protective base plate is placed at the lower end of the connecting base plate. During installation, the limiting pin is inserted into the limiting hole to achieve the limiting effect, prevent the protective base plate from rotating, and improve stability. One end of the fixing bolt passes through the protective base plate and is threadedly connected to the bolt hole to fix the protective base plate. The storage cavity is formed between the fence plate and the protective baffle, which protects the object and prevents it from falling to the ground and being damaged, thus improving safety. At the same time, it also has a storage effect, storing finished products on one side and objects to be spot welded on the other side, improving convenience. It solves the problem that the spot welding position of the existing spot welding machine lacks protection, and the objects are easy to fall and be damaged when the objects are placed and picked up for spot welding, resulting in low safety.

[0015] (2) By setting limit slots on the upper surface of both ends of the protective base plate, when installing the protective baffle, the protective baffle is placed on the upper end of the protective base plate. When placing it, the limit plate is inserted into the limit slot to limit the protective baffle and prevent it from falling off. The plug-in type of protective baffle makes it easy to quickly disassemble and install the protective baffle, improving flexibility. Attached Figure Description
