Description

Technical Field

[0001] The utility model relates to the technical field of welding devices, and particularly relates to a welding device for assembling filing cabinets. Background Technique

[0002] A filing cabinet is an outer shell for storing paper file bags. It has obvious internal layers and needs to install multiple groups of partition plates to separate and place file bags for convenient access without spending extra time searching. To improve the stability of the filing cabinet, welding equipment is required to assemble and fix it.

[0003] Previous welding devices were mostly hand-held welding torches, which required workers to squeeze the cabinet tightly to prevent excessive gaps and separation. However, the force of the human hand inevitably caused displacement of the filing cabinet during extrusion, which damaged the accuracy of the gap connection, and the fixed filing cabinet might be misaligned.

[0004] Now, a new welding device for assembling filing cabinets is proposed to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a welding device for assembling filing cabinets to solve the problem of inconvenient positioning mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A welding device for assembling filing cabinets, including a base plate and side rods. Both sides of the front end of the top of the base plate are fixed with side rods, and a servo motor is installed at the top of the outside of the side rods. A longitudinal groove is arranged between the upper and lower parts inside the side rods. A lead screw is movably connected in the longitudinal groove, and a first bushing is sleeved outside the lead screw. A horizontal rod is fixed between the front ends of the first bushings. A transverse groove is arranged between the two sides inside the horizontal rod. A screw rod is movably connected between the two sides inside the transverse groove. A motor is installed inside the left side of the horizontal rod. Second bushings are sleeved on both sides outside the screw rod, and a suspension rod is fixed below the second bushings. A clamping block is fixed at the bottom of the suspension rod, and balls are movably embedded on the surface of the clamping block.

[0007] Preferably, the output shaft of the servo motor is fixedly connected to the lead screw, and the outer wall of the lead screw meshes with the first bushing.

[0008] Preferably, the output shaft of the motor is fixedly connected to the left side of the screw rod, and the screw rod and the second bushings are arranged in concentric circles.

[0009] Preferably, a welding machine is installed at the center of the top of the horizontal rod. An installation block is fixed at the center of the bottom of the horizontal rod. A cylinder is installed in the front of the installation block. A push rod is fixed behind the piston rod of the cylinder. A micro motor is installed at the bottom left of the push rod. A welding head is movably connected between the two sides at the bottom rear of the push rod.

[0010] Preferably, the rear of the push rod is electrically connected to the welding machine, and the rear of the piston rod of the cylinder can guide the push rod to move.

[0011] Preferably, the rotating rod of the micro motor is fixedly connected to the welding head, and the welding head can swing up and down inside the push rod.

[0012] Preferably, a skateboard is provided between the two sides of the top of the base plate, and bottom blocks are respectively fixed between the front and rear of both sides of the bottom of the skateboard, rollers are installed at the front and rear ends of the bottom of the bottom block, five groups of grooves are provided on both sides of the top of the skateboard, and a swivel block is movably hinged on one side of the groove, a pull rod is installed at the center of the front end of the skateboard, slideways are respectively provided between the front and rear of both sides of the top of the base plate, and cabinets are placed on both sides of the top of the skateboard.

[0013] Preferably, the bottom block is embedded in a slideway, and the bottom block can slide back and forth along the slideway.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the welding device for assembling the filing cabinet not only realizes synchronous clamping of the cabinet body and adjustment of the welding head angle, but also facilitates pushing the cabinet body;

[0015] (1) A horizontal rod is fixed between the front ends of the first sleeves, and the cabinet is pushed to the top of the base plate with a slide plate. The servo motor at the top of the side rod is started to rotate the screw in the longitudinal groove, and then the first sleeve is guided downward to slide vertically, driving the horizontal rod welding equipment to slide. After the motor is turned on, the second sleeve can be retracted in the opposite direction, so that the second sleeve moves along the screw in the horizontal groove, forcing the block connected to the suspension rod to fit the cabinet surface with a ball bearing. At this time, the horizontal rod is also fitted to the front end of the cabinet, and the gap welding process can be performed from top to bottom;

[0016] (2) By installing a cylinder in front of the mounting block, the cylinder pushes the push rod backward, forcing the welding head to approach the gap at the joint in front of the cabinet, and then starting the micro motor to rotate the welding head by the output shaft of the micro motor, forcing the welding head to fit the cabinet surface, and then moving from top to bottom to perform heat welding, so that the device is suitable for cabinets of various specifications and realizes variable welding angles;

[0017] (3) A slide plate is arranged between the two sides of the top of the base plate, and the bottom block under the slide plate is embedded in the slideway by means of rollers. The slide plate can be moved forward and backward along the surface of the base plate by holding the pull rod at the front end, and then the rotary block in the groove is selected as a limit according to the width of the adjacent cabinets. This can assist in pre-joining and fixing the cabinets before the blocks are fitted together, and the cabinets can be taken out and put in very conveniently. BRIEF DESCRIPTION OF THE DRAWINGS
