Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, specifically a high-efficiency welding fixture for fixing brackets. Background Technology

[0002] A fixed support is a type of support used to fix and limit the position of pipes or equipment. Fixed supports are usually welded together from several angle irons or steel sheets. Welding fixtures are required when welding, and the welding fixtures are a set of clamps for welding, fixing, clamping and positioning.

[0003] Utility model application CN202221581042.5 discloses a welding fixture for a fixed bracket. A positioning cylinder pushes out the positioning block and the positioning pins and fixing pins at the top of the fixing end, allowing them to be inserted into the fixing holes of the weldment. This facilitates the alignment and fixing of the weldment, improving welding efficiency. After welding, the positioning pins and fixing pins retract under the action of the positioning cylinder, making it easy to disassemble the weldment.

[0004] The aforementioned device is inserted into the fixing holes of the welded parts by positioning pins and fixing pins to align and fix the welded parts. The positions of the positioning pins and fixing pins are fixed, and the positions of the fixing holes on the welded parts are also fixed. It can only fix welded parts of the same size and specification. If the welded parts are of different sizes, it cannot be aligned and fixed, and its applicability is low.

[0005] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0006] The purpose of this invention is to solve the above problems by designing a high-efficiency welding fixture for a fixed bracket.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A high-efficiency welding fixture for fixed supports includes a fixture base, a U-shaped support plate mounted on the surface of the fixture base, a transverse through groove on the U-shaped support plate, two sliding pads on the surface of the U-shaped support plate, guide sliders mounted at the bottom of the two sliding pads, the guide sliders being slidably connected to the transverse through groove, a transverse sliding groove on the sliding pad, a sliding magnetic block within the transverse sliding groove, a positioning pin mounted on the top of the sliding magnetic block, a vertical through hole on the sliding pad located on one side of the transverse sliding groove, a lifting pin within the vertical through hole, the bottom end of the lifting pin extending through and out of the transverse sliding groove, an L-shaped fixing plate mounted on the sliding pad, a clamping cylinder mounted on the horizontal arm end of the L-shaped fixing plate, the telescopic end of the clamping cylinder penetrating the L-shaped fixing plate, and a clamping block mounted on the telescopic end of the clamping cylinder.

[0009] Furthermore, a bidirectional threaded screw is rotatably connected to the C-shaped support plate, a drive motor is installed on one side of the C-shaped support plate, the output end of the drive motor is fixedly connected to one end of the bidirectional threaded screw, two movable sliders are threadedly connected to the bidirectional threaded screw, fixed support plates are installed on the movable sliders, and the top ends of the two fixed support plates are fixedly connected to the bottom ends of the two guide sliders.

[0010] Furthermore, a support base plate is installed on one side of the fixed support plate, and a telescopic cylinder is installed on the support base plate. The telescopic end of the telescopic cylinder is fixedly connected to the lifting pin.

[0011] Furthermore, the depth of the transverse groove is the same as the thickness of the sliding magnetic block, and multiple universal balls are provided on the inner walls of both sides of the transverse groove, with the two sides of the sliding magnetic block in contact with the universal balls.

[0012] Furthermore, the bidirectional threaded screw is provided with two threaded grooves with opposite helical directions, and the two movable sliders are respectively threadedly connected to the two threaded grooves, and the two movable sliders move in opposite directions.

[0013] Furthermore, a diagonal reinforcing rod is installed at the bottom of the horizontal arm end of the L-shaped fixing plate, and the end of the diagonal reinforcing rod away from the L-shaped fixing plate is fixedly connected to the surface of the sliding pad.

[0014] Compared with existing technologies, this technical solution has the following beneficial effects:

[0015] The position of the positioning pin can be adjusted by sliding the magnetic block. The welding joint is positioned by the lifting pin and the positioning pin to prevent the welding part from shifting. It is suitable for welding parts of different sizes and specifications, thus improving applicability.

[0016] The clamping block is raised and lowered by the clamping cylinder and pressed on the weldment to fix it, which improves the stability of the welding. The double-threaded screw is driven by the drive motor to rotate and the two moving sliders move relative to each other. The two moving sliders drive the guide slider to slide along the transverse through groove through the fixed support plate. The guide slider drives the sliding pad to slide on the C-shaped support plate. The two sliding pads move relative to each other, so that the two weldments are joined together, which improves the accuracy of the joining and the welding quality.

[0017] The use of omnidirectional ball bearings reduces the friction of the sliding magnetic block during movement, making it easier to slide the magnetic block. Attached Figure Description

[0026] Two weldable parts to be welded together are placed on two sliding pads 4 respectively. One fixing hole on the weldable part is inserted into the positioning pin 8. The weldable part is slid on the sliding pad 4. The weldable part drives the sliding magnetic block 7 to slide along the transverse groove 6 through the positioning pin 8. The position of the weldable part is adjusted so that the other fixing hole on the weldable part is aligned with the vertical through hole 9. The lifting pin 10 rises and is inserted into the fixing hole on the weldable part.

[0027] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 A bidirectional threaded screw 14 is rotatably connected to the C-shaped support plate 2. A drive motor 15 is installed on one side of the C-shaped support plate 2. The output end of the drive motor 15 is fixedly connected to one end of the bidirectional threaded screw 14. Two movable sliders 16 are threadedly connected to the bidirectional threaded screw 14. Fixed support plates 17 are installed on the movable sliders 16. The tops of the two fixed support plates 17 are fixedly connected to the bottoms of the two guide sliders 5.

[0028] The drive motor 15 starts working, and the output end of the drive motor 15 drives the bidirectional threaded screw 14 to rotate. The rotation of the bidirectional threaded screw 14 drives the two movable sliders 16 to move relative to each other. The two movable sliders 16 drive the guide slider 5 to slide along the transverse through groove 3 through the fixed support plate 17. The guide slider 5 drives the sliding pad 4 to slide on the U-shaped support plate 2. The two sliding pads 4 move relative to each other, so that the two welded parts are joined together.
