Description

Technical Field

[0001] The utility model relates to the technical field of stamping feeding, in particular to a fixture for a welding torch. Background Technique

[0002] The fixture for the welding torch plays a crucial role in welding production. It can improve the quality, efficiency and stability during the welding process, and ensure the accuracy and repeatability of the welded workpieces. In large-scale production, the higher the degree of automation of the welding fixture, the higher the production efficiency, and at the same time, it can reduce the fatigue strength of the personnel and human errors.

[0003] The existing fixture for the welding torch uses a cylinder to drive the movement of the welding torch. The cylinder does not have a buffering function, which easily leads to collisions of the welding torch during movement, and cannot ensure that the cylinder and the surface of the base are on the same horizontal plane. These are all problems that need to be solved in the utility model of a fixture for a welding torch. Content of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to provide a fixture for a welding torch with buffering and easy disassembly and assembly.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A fixture for a welding torch, comprising a base, a welding torch arranged at the upper end of a protective cover, and an oil tank arranged on the base. A hydraulic cylinder is fixedly connected above the oil tank. The output end of the hydraulic cylinder is fixedly connected with an L-shaped rod. The other end of the L-shaped rod penetrates through the welding torch. A protective cover is fixedly connected to the upper surface of the base. A guide rail is fixedly connected to the upper surface of the protective cover. A slider is slidably connected to the guide rail. The welding torch is fixedly connected to the upper surface of the slider.

[0007] Preferably, the protective cover includes two side plates and a top plate. The protective cover is fixedly connected to the upper surface of the base by welding.

[0008] Preferably, fixing plates are fixedly connected to the upper surface of the base and the inner surface of the protective cover. A hydraulic cylinder is installed on the upper surface of the fixing plate. Connecting plates are fixedly connected to both side surfaces of the hydraulic cylinder. The connecting plates are fixedly connected to the inside of the protective cover by stud bolts. The connection by stud bolts facilitates the disassembly and assembly of the hydraulic cylinder.

[0009] Preferably, the L-shaped rod is composed of a horizontal rod and a telescopic vertical rod. A sleeve is threadedly connected to the vertical rod. The other end of the sleeve is fixedly connected with a connecting rod. The connecting rod penetrates through one end of the welding torch. The telescopic vertical rod facilitates the disassembly and assembly of the welding torch.

[0010] Preferably, a limiting block is fixedly connected to the upper surface of the protective cover. The limiting block is used to prevent the welding torch from colliding and avoid accidents.

[0011] Preferably, the guide rail and the slider are connected by sliding, and lubricating oil is applied between the guide rail and the slider to make the welding torch run more smoothly on the guide rail.

[0012] Compared with the prior art, the utility model has the following advantages;

[0013] By changing the original cylinder drive, adding a horizontal block, and changing the connection method, the utility model has the advantages of buffering, ensuring horizontality, and being convenient for disassembly and assembly.

[0014] First, a new buffer and mechanism are added. The original cylinder is replaced with a hydraulic cylinder. Compared with the cylinder, the hydraulic cylinder has a function of smooth buffering. Since the hydraulic oil has viscosity, the hydraulic rod controlled by the hydraulic oil can play a buffering role. Compared with the cylinder, the hydraulic cylinder can control its movement speed and has a better protection effect on the mechanism.

[0015] Second, smooth sliding: A horizontal block is added on the original basis. In order to make the hydraulic cylinder slide more smoothly, a horizontal block is added below the hydraulic cylinder to ensure the horizontality of the hydraulic cylinder and ensure that the hydraulic rod is horizontal relative to the base during operation.

[0016] Third, convenient disassembly and assembly: On the original basis, the hydraulic rod and the side of the protective cover are connected by threads, which is beneficial to the disassembly and assembly of the hydraulic cylinder. It not only ensures the convenient disassembly and assembly of the welding torch, but also ensures the disassembly and assembly of the output mechanism.

[0017] Fourth, on the original basis, the chute is changed to a sliding mechanism with a guide rail and a slider, which is more convenient for maintenance and installation than the original chute. Description of the Drawings

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Figures 1 - 3 A fixture for a welding torch, including a base 1, a welding torch 12 arranged at the upper end of a protective cover 2, and a fuel tank 3 arranged on the base 1. A hydraulic cylinder 4 is fixedly connected above the fuel tank 3. The output end of the hydraulic cylinder 4 is fixedly connected with an L-shaped rod 10. The other end of the L-shaped rod 10 penetrates through the welding torch 12. The L-shaped rod 10 is composed of a horizontal rod and a telescopic vertical rod. A sleeve 11 is threadedly connected to the vertical rod. The other end of the sleeve 11 is fixedly connected with a connecting rod 16. The connecting rod 16 penetrates through one end of the welding torch 12. The disassembly and assembly of the welding torch horizontally can be controlled by controlling the length of the connecting rod 16. A protective cover 2 is fixedly connected to the upper surface of the base 1. Fixing plates 7 are fixedly connected to the upper surface of the base 1 and the inner surface of the protective cover 2. A hydraulic cylinder 4 is installed on the upper surface of the fixing plate 7. Connecting plates 5 are fixedly connected to both side surfaces of the hydraulic cylinder 4. The connecting plates 5 are fixedly connected to the inside of the protective cover 2 through stud bolts 6. Threaded connection is used to facilitate the disassembly and assembly of the hydraulic cylinder. The protective cover 2 includes two side plates and a top plate. The protective cover 2 is fixedly connected to the upper surface of the base 1 by welding. A limiting block 15 is fixedly connected to the upper surface of the protective cover 2. The limiting block 15 can prevent the welding torch from colliding and causing losses. A guide rail 13 is fixedly connected to the upper surface of the protective cover 2.

[0024] The functional principle of the present invention can be elaborated through the following operation modes:

[0025] The fuel tank fixed on the upper surface of the base 1 transports hydraulic oil to the hydraulic cylinder 4 through an oil inlet pipe 8. Then, the hydraulic rod 10 starts to move horizontally under the push of the hydraulic oil. The discharged oil will return to the fuel tank 3 through an oil outlet pipe 9. The L-shaped rod 10 connected to the hydraulic rod 10 will drive the welding torch 12 to perform a horizontal linear motion. The L-shaped rod 10 is composed of a horizontal rod and a telescopic vertical rod. The telescopic vertical rod is for the convenience of disassembling and assembling the welding torch 12. The welding torch 12 is fixedly connected to the slider 14. The slider 14 is slidably connected to the guide rail 13. The guide rail 13 is fixedly connected to the upper surface of the protective cover 2. A limiting block 15 is fixedly connected to one end of the guide rail 13 to prevent the welding torch 12 from exceeding the moving range. The hydraulic cylinder 4 is threadedly connected to the side of the protective cover 2 for the convenience of disassembly and assembly. The hydraulic cylinder 4 is located on the positioning plate 7 to ensure that the hydraulic cylinder 4 and the base 1 are on the same horizontal plane.
