Description

Technical Field

[0001] The utility model relates to the technical field of positioning devices, in particular to a gearbox casing welding positioning tool. Background Art

[0002] The transmission housing, also known as the transmission case or transmission casing, is a key component of the automotive transmission system, carrying the transmission mechanism and its associated accessories. During the manufacturing process, some transmission cases require joining different metal parts, often through welding. To ensure the stability of the transmission case during welding, a positioning device is often used to secure it.

[0003] However, most existing positioning devices only clamp and fix the gearbox casing through a clamping plate. When welding is required on different surfaces of the gearbox casing, the gearbox casing needs to be loosened, manually rotated, and the processing surface needs to be adjusted before clamping and fixing it again. In addition, some gearbox casings need to be turned over during further processing to facilitate processing inside them, which is time-consuming, labor-intensive, and inconvenient. Utility Model Content

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1 to 3 shown, a welding positioning tooling for a gearbox housing includes a workbench 1, a support assembly installed on the top of the workbench 1, and clamping assemblies symmetrically arranged on both sides of the support assembly.

[0022] The support assembly includes a base 2, a support plate 3 is arranged above the base 2, a rotary cylinder 1 4 for driving the support plate 3 to rotate is installed on the top of the base 2, a groove is formed on the top surface of the base 2, the rotary cylinder 1 4 is installed inside the groove, a circular rail 5 is fixedly installed on the top surface of the base 2 outside the groove, and a slider 6 slidably connected to the circular rail 5 is fixedly connected to the bottom of the support plate 3.

[0023] Place the gearbox housing on the top of the support plate 3, and the rotary cylinder 1 4 drives the support plate 3 to rotate, so that the rotation of the gearbox housing can be realized, and then it is convenient to weld different surfaces of the gearbox housing.

[0024] The clamping assembly includes a fixed column 7, an installation frame 8 is movably connected to one side of the fixed column 7 close to the base 2. The installation frame 8 is a U-shaped frame, and limiting strips 13 are symmetrically and fixedly connected to both sides inside it. Sliding grooves adapted to the limiting strips 13 are symmetrically formed on both sides of the fixed column 7. A rotary cylinder 2 9 is installed outside the installation frame 8, a telescopic cylinder 10 is installed at the output end of the rotary cylinder 2 9, a clamping plate 11 is installed at the output end of the telescopic cylinder 10, and an anti-slip pad 12 is bonded to the clamping surface of the clamping plate 11.

[0025] The distance between the two clamping plates 11 can be adjusted by the telescopic movement of the telescopic cylinder 10, and the two clamping plates 11 are used to clamp and fix both sides of the gearbox housing. When the gearbox housing needs to be flipped, the two rotary cylinders 2 9 drive the two telescopic cylinders 10 to rotate in the same direction at the same time, so that the flipping of the gearbox housing can be realized.

[0026] A driving assembly for driving the installation frame 8 to move up and down is installed on the fixed column 7. A fixed groove is formed on one side of the fixed column 7 close to the base 2. The driving assembly includes a driving block 14 movably arranged inside the fixed groove, and a lead screw 15 penetrating and threadedly connected to the driving block 14 is rotatably installed inside the fixed groove. A motor 16 for driving the lead screw 15 to rotate is installed on the top of the fixed column 7, and the driving block 14 is fixedly installed inside the installation frame 8.

[0027] The controller controls the two motors 16 to work simultaneously, and the two lead screws 15 rotate, prompting the two driving blocks 14 to rise or fall simultaneously, so as to realize the adjustment of the height of the clamping plate 11.

[0028] In specific use, place the gearbox housing on the top of the support plate 3, adjust the clamping plate 11 to a suitable height, and the telescopic cylinder 10 extends to prompt the two clamping plates 11 to clamp and fix both sides of the gearbox housing. At this time, parts can be welded on the front and back sides of the gearbox housing. When welding other surfaces of the gearbox housing is required, the telescopic cylinder 10 contracts and returns to its original position, and the rotary cylinder 1 drives the support plate 3 to rotate, so that the welding surface can be located at the front or rear end of the device. The telescopic cylinder 10 extends again to fix the gearbox housing with the clamping plate 11, and then welding can be carried out. When the gearbox housing needs to be flipped, the two motors 16 work simultaneously and the clamping plate 11 clamps and lifts the gearbox housing to a certain height, and the rotary cylinder 2 drives the telescopic cylinder 10 and the clamping plate 11 to rotate 180°, so that the flipping of the gearbox housing can be realized. After the flipping is completed, the motor 16 drives the clamping plate 11 to descend, so that the gearbox housing can be placed on the support plate 3 for subsequent processing.
