[0018] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0019] The embodiments of this utility model relate to a welding fixture for processing the control box body, such as... Figure 1-5 As shown, the device includes a tooling plate 1 and an inner support plate 4. Four L-shaped limiting blocks 6 arranged in a rectangular pattern are mounted on the upper end of the tooling plate 1, forming a rectangular placement space for installing the control box body 5. Two double mounting positions 7 are arranged on the upper end of the tooling plate 1 at the front, back, left, and right sides of the placement space. Each double mounting position 7 is equipped with a clamping device 3. Each double mounting position 7 includes a long through hole 8 and two circular through holes 9. Each end of the long through hole 8 is connected to a circular through hole 9. Around each circular through hole 9, a cylinder fixing hole group 10 and a rotating seat fixing hole group 16 are arranged. The clamping device 3 includes a clamping cylinder 11 and a rotating... The clamping cylinder 11 is fixedly installed in one of the cylinder fixing hole groups 10. The clamping cylinder 11 is located below the tooling plate 1. The rotating seat 12 is fixedly installed in the corresponding rotating seat fixing hole group 16. The piston rod of the clamping cylinder 11 passes through the circular through hole 9 and is rotatably connected to the pressure plate 13. The lower part of the free end of the pressure plate 13 is screwed with an adjusting bolt 15. A connecting plate 14 is rotatably installed on each side of the middle part of the pressure plate 13. The two connecting plates 14 are rotatably connected to the two sides of the rotating seat 12 respectively. The inner support plate 4 is placed in the control box 5. The inner support plate 4 is a rectangular plate structure. An arc-shaped notch 17 is opened at each of the four corners of the inner support plate 4.

[0020] During processing, the control box 5 is first placed into the space enclosed by four L-shaped limiting blocks 6. The four L-shaped limiting blocks 6 limit the control box 5. Then, the inner support plate 4 is placed inside the control box 5. The inner support plate 4 supports the inner wall of the control box 5 through its sides. The arc-shaped notches 17 at the four corners of the inner support plate 4 provide sufficient welding space. The arc-shaped notches 17 mainly facilitate the welding process port of the welding gun, making it easy for the welding gun to enter. The clamping device 3 is activated, and the clamping cylinder 11 controls the lifting of one end of the pressure plate 13 and the pressing of the adjusting bolt 15 at the other end. Through several clamping devices 3, the inner support plate 4 is pressed down, realizing the positioning and clamping of the control box 5. The worker uses the welding gun 21 to weld the edge seams at the four corners inside the control box 5. Welding can be done manually, semi-automatically, or in the field of robotic welding.

[0021] Each double mounting position 7 has two mounting positions for the clamping device 3, one on the inner side and the other on the outer side. The L-shaped limit block 6 is connected to the tooling plate 1 by fasteners. The number of four L-shaped limit blocks 6 can be reduced as needed, and generally two or four are used. Simultaneously, four L-shaped limiting blocks 6 are used to correspond to a small-sized control box body 5, with all clamping devices 3 installed on the inner side. The two L-shaped limiting blocks 6 on the right are removed, leaving the two on the left. The positions of the two clamping devices 3 on the right are adjusted to the outer positions, thus producing a relatively long control box body 5. The control box body 5 is limited by the two L-shaped limiting blocks 6 on the left, and internally limited by an inner support plate 4 of the same specification. Several clamping devices 3 press down on the inner support plate 4 to achieve positioning and clamping of the control box body 5. The two L-shaped limiting blocks 6 on the front are removed, leaving the two on the rear. The positions of the two clamping devices 3 on the front are adjusted to the outer positions, thus producing a relatively long control box body 5. This invention can achieve welding of three sizes of control box bodies.

[0022] The tooling plate 1 has a mounting cabinet 2 at its lower part. The mounting cabinet 2 is used to place the electrical components that are matched with the clamping cylinder 11. The mounting cabinet 2 not only protects the clamping cylinder 11 and the electrical components, but also improves the aesthetics. The mounting cabinet 2 has a button on its side for controlling the clamping cylinder 11.

[0023] As a preferred embodiment of the inner support plate 4, the inner support plate 4 is provided with a plurality of protrusions 18 evenly arranged around its perimeter. The protrusions 18 are in the form of isosceles trapezoidal blocks. The evenly arranged protrusions 18 are used to support the inner wall of the control box body 5.

[0024] As a preferred embodiment of the inner support plate 4, the inner support plate 4 has multiple rectangular cutouts 20 arranged side by side in the middle. The rectangular cutouts 20 not only reduce the weight of the inner support plate 4, but also facilitate the removal of the inner support plate 4.

[0025] As a preferred embodiment of the clamping cylinder 11, the upper end of the clamping cylinder 11 is provided with a frustum 19 sleeved outside the piston rod, and the frustum 19 is engaged with the circular through hole 9.

[0026] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0027] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0028] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
