Description

Technical Field

[0001] This utility model relates to the field of welding fixtures for electric excavator trailer supports, specifically a welding fixture for electric excavator trailer supports. Background Technology

[0002] Traditional welding methods, due to the limitations of manual operation, often struggle to guarantee welding precision and consistency. However, welding fixtures, through modular design and intelligent technology, can precisely assemble and fix components of different shapes, reducing weld defects caused by improper manual operation and significantly improving welding quality. The design of these welding fixtures also makes the operation process more convenient and easier for operators to use, while simultaneously enhancing safety and reducing the potential risk of accidents.

[0003] During use, tooling fixtures may become loose or deformed. Loose fixtures can cause workpieces to move during welding, affecting welding quality. Deformation of existing electric excavator tractor bracket welding tooling fixtures can lead to welding position shifts or reduced welding quality, failing to meet the requirements for clamping and fixing workpieces. Existing tooling fixtures of this type are generally not conducive to convenient clamping and supporting of electric excavator tractor brackets, making it inconvenient to perform welding operations on multiple internal parts of the electric excavator tractor bracket, and making it inconvenient to perform multi-position, multi-angle rotation welding operations. This greatly affects the rotation adjustment range of the welded parts and the efficiency of welding tooling. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding fixture for an electric excavator tractor support, comprising a support plate and a workbench. The workbench is mounted on the top of the support plate, and multiple sets of support columns are mounted on the top of the workbench. A welding component body is placed on the top of each support column, and multiple sets of pressure plates are provided on the top of each welding component body. Multiple sets of threaded columns are mounted on both sides of each set of support columns, and threaded caps are fitted onto the surface of each threaded column. An L-shaped plate is provided on the outside of the support plate, and a rotating box is mounted on the side wall of the L-shaped plate. A rotating shaft is movably mounted inside the rotating box, extending through the rotating box to the side wall of the support plate. A worm gear is fitted onto the surface of the rotating shaft. A servo motor is mounted on the side wall of the rotating box, and a rotating rod is mounted on the output end of the servo motor.

[0014] (1) When the welded part body needs to be welded, the welded part body is an electric excavator tractor bracket, which is composed of multiple sets of parts. The multiple sets of parts are placed on the top of the support column and supported by the support column. The multiple sets of pressure plates are pressed on the surface of the multiple sets of parts under the support of the threaded column. The threaded cap is turned to fix the welded part body under the threaded engagement of the threaded column and the threaded cap.

[0025] Please see Figure 1-7 An embodiment of this utility model provides: a welding fixture for an electric excavator tractor support, including a support plate 4 and a workbench 5. The workbench 5 is installed on the top of the support plate 4. Multiple sets of support columns 7 are installed on the top of the workbench 5. A welding body 6 is placed on the top of the support column 7. Multiple sets of pressure plates 10 are provided on the top of the welding body 6. Multiple sets of threaded columns 8 are installed on both sides of the multiple sets of support columns 7. Threaded caps 9 are fitted on the surface of each threaded column 8. An L-shaped plate 3 is provided on the outside of the support plate 4. A rotating box 12 is installed on the side wall of the L-shaped plate 3.

[0026] A threaded sleeve 21 is installed at the center of the bottom end of the L-shaped plate 3. Four sets of equally spaced sliders 22 are installed on the outside of the threaded sleeve 21 at the bottom end of the L-shaped plate 3. A horizontal support 2 is provided at the bottom end of the L-shaped plate 3.

[0027] A stepper motor 18 is installed on the side wall of the transverse support 2. A threaded rod 19 is movably installed inside the transverse support 2. Both ends of the threaded rod 19 extend to the surface of the transverse support 2, and one end of the threaded rod 19 is connected to the output end of the stepper motor 18.

[0028] The threaded rod 19 is threadedly connected to the threaded sleeve 21. Limiting rods 20 are installed on both sides of the threaded rod 19 inside the transverse bracket 2. The limiting rods 20 are slidably connected to the slider 22.

[0029] When welding is required on the main body 6, which is an electric excavator trolley bracket, the main body 6 is composed of multiple sets of parts. These parts are placed on the top of the support column 7 and supported by it. Multiple pressure plates 10, supported by threaded columns 8, press against the surfaces of the parts. Tightening the threaded cap 9, with the threaded engagement between the threaded column 8 and the threaded cap 9, secures the main body 6, facilitating the fixing of the multiple parts and subsequent welding operations. When the welding side needs to be rotated, the servo motor 13 is activated. Supported by the rotating box 12, the servo motor 13 drives the rotating rod 14 to rotate. The rotating rod 14 drives the worm gear 15 to rotate. With the worm gear 15 meshing with the worm wheel 16, the worm gear 15 drives the worm wheel 16 to rotate, which in turn drives the rotating shaft 17 to rotate. The rotating shaft 17 drives the support plate 4, worktable 5, and welding part body 6 to rotate in a circular motion around the rotating shaft 17 at a certain angle, which facilitates welding at different positions. When the welding part is too long and needs to be moved, the stepper motor 18 is turned on. Under the support of the horizontal bracket 2, the stepper motor 18 drives the threaded rod 19 to rotate. Under the limit of the limit rod 20 and the slider 22, the threaded rod 19 drives the threaded sleeve 21 to move.

[0032] Turn on the variable frequency motor 23. With the support of the horizontal bracket 2, the variable frequency motor 23 drives the gear 24 to rotate. With the meshing of the gear 24 and the gear disk 25, and with the support of the hollow sleeve 11 and the gear disk 25, the gear 24 drives the rotating column 26, the horizontal bracket 2, the L-shaped plate 3, the support plate 4, the worktable 5, and the welding part body 6 to rotate around the gear disk 25 with the hollow sleeve 11 as the axis. This allows for a second rotation adjustment of the welding part, realizing the circumferential rotation adjustment of the welding fixture to adjust the position of the welding part, increasing the rotation adjustment range of the welding part, and improving the flexibility of the rotation adjustment of the welding fixture.

[0033] Working principle: When the welding body 6 needs to be welded, the welding body 6 is an electric excavator trolley bracket. The welding body 6 is composed of multiple sets of parts. The multiple sets of parts are placed on the top of the support column 7 and supported by the support column 7. The multiple sets of pressure plates 10 are pressed onto the surface of the multiple sets of parts under the support of the threaded column 8. Tightening the threaded cap 9 fixes the welding body 6 with the threaded engagement of the threaded column 8 and the threaded cap 9, which facilitates the fixation of the multiple sets of parts and the subsequent welding of the multiple sets of parts. When it is necessary to rotate the welding side, the servo motor 13 drives the rotating rod 14 to rotate. The rotating rod 14 drives the worm gear 15 to rotate. The worm gear 15 drives the worm wheel 16 to rotate. The worm wheel 16 drives the rotating shaft 17 to rotate. The rotating shaft 17 drives the support... The support plate 4, worktable 5, and welding part body 6 rotate circumferentially around the rotating shaft 17 at a certain angle to facilitate welding at different positions. When the welding part is too long and needs to be moved, the stepper motor 18 drives the threaded rod 19 to rotate. The threaded rod 19 drives the threaded sleeve 21 to move. The threaded sleeve 21 drives the L-shaped plate 3, support plate 4, worktable 5, and welding part body 6 to move to the processing area. The frequency converter motor 23 drives the gear 24 to rotate. The gear 24 drives the rotating column 26, horizontal bracket 2, L-shaped plate 3, support plate 4, worktable 5, and welding part body 6 to rotate circumferentially around the gear plate 25 around the hollow sleeve 11, and the welding part is rotated and adjusted again to complete the use of the electric support bracket welding fixture.
