Description

Technical Field

[0001] This utility model belongs to the field of welding fixture technology, specifically relating to a cantilever welding fixture. Background Technology

[0002] Welding fixtures are a set of flexible welding fixation, clamping, and positioning jigs; they are mainly used for welding various weldable materials, including large, medium, and small materials.

[0003] Existing cantilever welding fixtures are generally adjusted in a straight line to move the clamped welding material. For some welding materials with curved surfaces, their flexibility is low and it is difficult to perfectly match the welding equipment. Therefore, it is necessary to design a cantilever welding fixture with good compatibility. Utility Model Content

[0004] The purpose of this invention is to provide a cantilever welding fixture, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cantilever welding fixture includes a main frame assembly, a crossbeam assembly at the top of the main frame assembly, a hanger fixedly connected to one end of the crossbeam assembly, a rotation control assembly on the inner wall of the hanger, a clamping assembly at the bottom of the hanger, and a slide rail at the bottom of the main frame assembly.

[0007] The rotary control assembly includes a main rotary control motor fixedly mounted above the hanger. The output shaft of the main rotary control motor is fixedly connected to a large rotating rod via a coupling. One end of the large rotating rod is fixedly connected to a turntable. A vertical plate is fixedly connected to the bottom of the turntable. An auxiliary rotary control motor is fixedly connected to the outer wall of the vertical plate. The output shaft of the auxiliary rotary control motor is fixedly connected to a small rotating rod via a coupling. Through the rotary control assembly, in use, the main rotary control motor is started and controlled to drive the turntable to rotate around the large rotating rod as the rotation axis. Simultaneously, the turntable rotates along the inner wall of the hanger, thereby adjusting the clamping assembly and the position of the clamped welding part. This, combined with the main frame assembly, allows for linear movement and adjustment of the welding part, enabling multi-directional control of the welding part and flexible lateral adjustment of the welding part's angle according to welding requirements.

[0008] The clamping assembly includes a middle plate fixedly mounted at one end of a small rotating rod. A claw clamp is movably connected to the inner wall of the middle plate, and a claw motor is fixedly connected to the outer wall of the middle plate. The output shaft of the claw motor is fixedly connected to a rotating shaft via a coupling, and the outer wall of the rotating shaft is fixedly connected to the inner wall of the claw clamp. By setting up the clamping assembly, in use, starting and controlling the claw motor can drive the claw clamp to rotate, thereby clamping and fixing the outer wall of the workpiece to be welded, ensuring the stability of the workpiece during welding. In conjunction with the use of the auxiliary rotary control motor on the rotary control assembly, the clamping assembly and the workpiece within it are driven to rotate along the small rotating rod to adjust the position of the workpiece. Furthermore, in conjunction with the main frame assembly, the workpiece is moved linearly to adjust its position, achieving multi-directional control of the workpiece and thus achieving better cooperation with the welding equipment.

[0009] The crossbeam assembly includes a horizontal piece with an upper limit slide bar at its bottom. One end of the horizontal piece is fixedly connected to an end plate, and rollers are movably connected to the inner wall of its bottom. Through the crossbeam assembly and its use in conjunction with the main frame assembly, the crossbeam assembly is slid along the connection direction by starting and controlling the drive motor, using the friction between the drive rollers and the horizontal piece. This allows for linear lateral adjustment of the crossbeam assembly and the mechanism connected to it along the inner wall of the upper limit side seat. Combined with the main lifting hydraulic cylinder in the main frame assembly, the overall height of the fixture can be adjusted to suit the external shape of the workpiece to be welded.

[0010] The main frame assembly includes a lower support base, a main lifting hydraulic cylinder fixedly connected to the bottom of the lower support base, an upper support base fixedly connected to the top of the lower support base via the main lifting hydraulic cylinder, an upper limit side seat fixedly connected to the top of the upper support base, several drive motors fixedly connected to the top of the upper support base, and drive rollers fixedly connected to the output shafts of the drive motors via couplings. The outer wall of the drive rollers is in contact with the bottom of the horizontal material, and a slide block is fixedly connected to the bottom of the lower support base. The outer wall of the slide block is in a movable connection with the outer wall of the slide rail.

[0011] In a preferred embodiment of this utility model, a motor frame is fixedly installed on the top of the hanger, and the bottom of the motor frame is fixedly connected to the outer wall of the main rotary motor.

[0012] As a preferred embodiment of this utility model, the inner wall of the hanger is provided with a limiting bearing groove, and the inner wall of the limiting bearing groove is fitted and connected to the outer wall of the turntable; by setting the limiting bearing groove, a better bearing and limiting effect on the outer wall of the turntable can be achieved.

[0013] As a preferred embodiment of this utility model, there are multiple claw clamps, the outer wall of the claw clamps is movably connected to the inner wall of the middle plate, and every two claw clamps and one claw motor are used in combination. By setting multiple claw clamps and claw motors, the clamping control position of the claw clamps at different positions can be flexibly adjusted according to the external shape of the workpiece to be welded, thereby improving the cooperation effect between the clamping components and the workpiece to be welded.

[0014] As a preferred embodiment of this utility model, the inner wall of the upper limit side seat is provided with a limiting groove, and the inner wall of the limiting groove is fitted and connected to the outer wall of the upper limit slide. By the fitting and connection of the inner wall of the limiting groove to the outer wall of the upper limit slide, the stability of the crossbeam assembly can be ensured during the sliding process, and the relative movement position of the cross material and the upper limit side seat can be limited.

[0015] In a preferred embodiment of this utility model, there are multiple main lifting hydraulic cylinders, and a protective sleeve is fixedly connected between the lower support and the upper support. The protective sleeve is a plastic folding protective sleeve with ventilation holes on its outer wall. The protective sleeve is set around the periphery of the multiple main lifting hydraulic cylinders. By setting the protective sleeve, a better protective effect can be achieved on the outside of the main lifting hydraulic cylinders.

[0016] As a preferred embodiment of this utility model, the number of clamping components is two, and the two clamping components are symmetrically located at the bottom of the rotary control component.

[0017] Compared with the prior art, the beneficial effects of this utility model are: by setting the rotary control component, in use, the main rotary control motor is started and controlled to drive the turntable to rotate around the large rotating rod as the rotation axis. At the same time, the turntable rotates along the inner wall of the hanger, thereby realizing the adjustment of the clamping component and the position of the clamped welding part. Then, in conjunction with the main frame component, the welding part is adjusted by linear movement, so as to achieve multi-directional control of the welding part, so as to flexibly adjust the angle of the welding part laterally according to the welding needs.

[0018] By setting up the clamping assembly, the start and control of the gripper motor during use can drive the gripper to rotate, thereby clamping and fixing the outer wall of the workpiece to be welded, ensuring the stability of the workpiece during welding. In conjunction with the use of the auxiliary rotary control motor on the rotary control assembly, the clamping assembly and the workpiece in the clamping assembly are driven to rotate along the small rotating rod to adjust the position of the workpiece. Then, in conjunction with the main frame assembly, the workpiece is moved linearly to adjust it, so as to achieve multi-directional control of the workpiece and thus achieve a better working effect with the welding equipment.

[0019] By setting up the crossbeam assembly and using it in conjunction with the main frame assembly, the crossbeam assembly is slid along the connection direction by starting and controlling the drive motor, and the friction between the drive roller and the cross material. This allows for linear lateral adjustment of the crossbeam assembly and the mechanism connected to it along the inner wall of the upper limit side seat. In conjunction with the main lifting hydraulic cylinder in the main frame assembly, the overall height of the tooling can be adjusted to match the external shape of the workpiece to be welded.
