Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to an automatic welding equipment for aluminum alloy housings. Background Technology

[0002] Most aluminum alloy housings are rectangular in shape. During processing, welding equipment is sometimes required to weld and fix the parts of the housing that need to be welded.

[0003] However, most aluminum alloy thin-walled shell welding devices are currently designed for fixed welding of the same type of product. Therefore, when welding different products, it is necessary to change the clamps to fix the product. This process is quite troublesome, making it inconvenient to use and resulting in poor equipment practicality. Utility Model Content

[0004] The purpose of this invention is to provide an automatic welding device for aluminum alloy shells, which can fix shells of different sizes with a single clamp, thereby improving the practicality of the device.

[0005] To achieve the above objectives, this utility model provides an automatic welding device for aluminum alloy housings, including an electrical control cabinet body. The top of the electrical control cabinet body is provided with a Y-axis module and a Z-axis module electrically connected thereto. A welding module is provided on the front side of the Z-axis module. It also includes an auxiliary mechanism. The auxiliary mechanism includes an X-axis guide rail slider device, a servo motor, a transmission screw, a slide block, a positioning plate, an adjusting seat, a clamping plate, an adjusting screw, a cylinder, and a mating device. The X-axis guide rail slider device is located on the top front side of the electrical control cabinet body. The servo motor is fixed to the right side of the electrical control cabinet body and electrically connected to it. The transmission screw is rotatably mounted on the top of the electrical control cabinet body, and its T-shaped mating nut is fixed to the mounting part at the bottom of the slide block and connected to the servo motor via a coupling. The slide block is bolted to the linear slider of the X-axis guide rail slider device. The positioning plate is mounted on the top of the slide block. The adjusting seat is mounted on a moving plate, and the moving plate is connected to the output end of the cylinder. The adjusting screw is integrally formed with the clamping plate and locked onto the adjusting seat by two nuts. A guide rod is provided on the clamping plate. The cylinder is fixed to the positioning plate. The mating device is located on the left side of the electrical control cabinet body and electrically connected to it.

[0006] The welding module includes a connecting arm and a welding machine body. The connecting arm is bolted to the vertical slide of the Z-axis module. The welding machine body is electrically connected to the electrical control cabinet body and is installed on the front side of the connecting arm.

[0007] The fitting device includes a support plate and a CNC panel. The support plate is fixed to the left rear side of the electrical control cabinet body. The CNC panel is electrically connected to the electrical control cabinet body and is mounted on the support plate.

[0008] The guide rods on the clamping plate are symmetrically arranged and slidably connected to the adjusting seat.

[0009] The automatic welding equipment for the aluminum alloy shell also includes a support mechanism, which includes a fixed plate and a threaded seat. The fixed plate is welded to the T-shaped support foot at the bottom of the electrical control cabinet body. The threaded seat is threaded to the fixed plate and passes through the fixed plate, and is T-shaped.

[0010] This utility model discloses an automatic welding device for aluminum alloy shells. During welding, the shell is placed in the mating groove of the positioning plate, with the rear and left and right sides of the shell respectively fitting into the mating groove. Then, the cylinder is controlled to move the moving plate, thereby moving the clamping plate and clamping it against the front end face of the shell. Then, the servo motor drives the transmission screw to move, and with the cooperation of the X-axis guide rail slider device, the slide block moves, thereby achieving horizontal movement of the workpiece. Then, the Y-axis module and Z-axis module drive the welding module to move back and forth and vertically, respectively, for welding. When it is necessary to fix shells of different lengths, the two fixing nuts of the adjusting screw are loosened, and then the adjusting screw is pulled directly to adjust the position of the clamping plate. Finally, when the desired position is reached, the two fixing nuts are locked. Since the extension length of the cylinder is fixed, the position of the clamping plate can be adjusted to clamp and fix shells of different lengths, thus enabling a single clamp to fix shells of different sizes, which improves the practicality of the equipment.

The two mounting ends of the transmission screw 106 are respectively mounted on detachable bearing seats by rotating bearings, and their T-shaped mating nuts are fixed in the through holes of the rectangular mounting part at the bottom of the slide block 107 by bolts.The positioning plate 108 is connected to the slide block 107 via positioning pins and bolts arranged from bottom to top. The positioning plate 108 is provided with a U-shaped groove structure that mates with the rectangular housing. The cylinder 112 is fixed to the positioning plate 108 by bolts, and a disc is connected to the output end by countersunk bolts. The disc is connected to the moving plate 117 by bolts. The moving plate 117 is a composite plate, which forms an integral support structure after being bolted to the U-shaped adjusting seat 109.

Then, the cylinder 112 is controlled to move, driving the moving plate 117 to move the clamping plate 110, which then abuts against the front end face of the housing to clamp it. Then, the servo motor 105 drives the transmission screw 106 to move, and with the cooperation of the X-axis guide rail slider device 104, the slide block 107 moves, thereby achieving horizontal movement of the workpiece. The Y-axis module 102 and the Z-axis module 103 respectively drive the welding module to move back and forth and vertically for welding. When it is necessary to fix shells of different lengths, loosen the two fixing nuts of the adjusting screw 111, and then directly pull the adjusting screw 111 to adjust the position of the clamping plate 110.

The bottom of the threaded seat 202 is an abutment plate, the abutment plate has an external hexagonal column, and the top of the external hexagonal column is an external threaded column.

[0026] In this embodiment, to facilitate equipment movement, universal self-locking wheels can be installed at the bottom of the support feet at the bottom of the electrical control cabinet body 101. After the equipment is moved to the location of use, the threaded seat 202 can be rotated by wrench by engaging the external hexagonal column until the abutment plate at the bottom of the threaded seat 202 abuts against the ground and stops rotating. This increases the support structure after the equipment is moved, improving the stability of the equipment. The installation of the fixing plate 201 and the threaded seat 202 does not interfere with the operation of the universal self-locking wheels.
