Description

Technical Field

[0001] The utility model relates to the technical field of welding fixtures, in particular to a welding fixture used for welding and forming an aluminum box. Background Art

[0002] The aluminum box is a box made of high-quality aluminum alloy profiles. It has a series of significant characteristics and a wide range of applications. During the production process of the aluminum box, welding is required to connect the various components.

[0003] After searching, the patent number CN218592194U discloses an aluminum alloy box welding fixture. The welding fixture is equipped with a transverse drive mechanism, a longitudinal drive mechanism, a No. 1 drive plate and a No. 2 drive plate. The position of the No. 1 drive plate and the No. 2 drive plate can be adjusted through the cooperation of the No. 1 cylinder, the No. 1 push plate, the No. 3 cylinder and the No. 2 push plate, so as to realize the clamping and fixing function of the aluminum alloy box and ensure the stability of the welding work.

[0004] However, when the above-mentioned clamp is clamping and positioning the aluminum box, it directly wraps and clamps the outer side of the aluminum box, so that welding can only be done at the joints of the upper and lower boxes on the outer side during welding, and the inner argon arc welding gun cannot weld the root. At the same time, there are bends on the outer sides of some aluminum boxes, but larger welding seams are likely to appear during welding, and the current needs to be increased during argon arc welding, resulting in welding deformation. Utility Model Content

[0008] A welding fixture for aluminum box welding and forming, comprising a bottom plate, a plurality of horizontal clamps arranged at intervals are fixedly provided around the top of the bottom plate, two symmetrically arranged outer limit blocks are fixedly provided at both ends of the top of the bottom plate, a support column is fixedly provided between two adjacent outer limit blocks, two symmetrically arranged corner cylinders are fixedly provided on the top of each support column, a horizontal pressing plate is provided between two adjacent outer limit blocks, a push-out cylinder is fixedly provided at the four corners of the top of the horizontal pressing plate, and an inner clamp block is fixedly provided at the end of the output shaft of the push-out cylinder;

[0009] The bottom plate is provided with a plurality of positioning grooves, and positioning pins are passed through the positioning grooves.

[0010] Preferably, a guide limiting groove is provided at the lower end of the inner wall of the outer limiting block.

[0011] Preferably, the bottom plate is arranged in a ring shape.

[0012] Preferably, a plurality of mounting holes are provided inside the bottom plate, and the mounting holes are arranged in cooperation with the horizontal clamp.

[0013] Furthermore, an anti-slip annular groove is provided on the upper end of the outer wall of the positioning pin.

[0014] Preferably, the spacings between the plurality of positioning pins are different.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] 1. The utility model can quickly clamp and position the aluminum box and the side panels to be welded inside and outside through the bottom plate, horizontal clamp, external limit block, corner cylinder, positioning pin, horizontal pressure plate, push cylinder and internal clamp block, so as to ensure the welding accuracy and avoid the appearance of welds as much as possible.

[0017] 2.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model embodiment discloses a welding fixture for welding and forming an aluminum box.

[0027] Example 1

[0028] The utility model provides Figure 1-4 A welding fixture for aluminum box welding and forming shown in the figure comprises a bottom plate 1, which is arranged in a ring shape, and a plurality of horizontal clamps 2 arranged at intervals are fixedly arranged around the top of the bottom plate 1, and two symmetrically arranged outer limit blocks 3 are fixedly arranged at both ends of the top of the bottom plate 1, and a support column 4 is fixedly arranged between two adjacent outer limit blocks 3, and two symmetrically arranged corner cylinders 5 are fixedly arranged on the top of each support column 4, and a horizontal pressing plate 6 is arranged between two adjacent outer limit blocks 3, and push-out cylinders 7 are fixedly arranged at the four corners of the top of the horizontal pressing plate 6, and an inner clamp block 8 is fixedly arranged at the end of the output shaft of the push-out cylinder 7;

[0029] The bottom plate 1 is provided with a plurality of positioning grooves 9 , and positioning pins 10 are inserted into the positioning grooves 9 .

[0030] Before welding the aluminum box, place the aluminum box on the bottom plate 1, and make the mounting hole of the aluminum box 1 body match the positioning groove 9. At this time, the aluminum box can be quickly positioned before clamping by plugging the positioning pin 10 and the positioning groove 9. After the position of the aluminum box is determined, the outer wall of the aluminum box is limited by the outer limit block 3. At this time, the side panel to be welded can be placed on the top of the aluminum box, and the horizontal pressing plate 6 is set on the top of the aluminum box 1. Then, start pushing multiple horizontal clamps 2 so that the horizontal clamps 2 press and limit the bottom of the aluminum box 1. At the same time, start the corner cylinder 5 and the push cylinder 7 to clamp the top and inner side of the side panel to be welded, so as to complete the clamping and fixing of the aluminum box before the overall welding, ensure the stability of the aluminum box during welding, avoid the occurrence of welds as much as possible, and improve the welding accuracy.

[0031] Example 2

[0032] Example 2 is based on Example 1 in order to stabilize the side position of the aluminum box before welding. Figure 1As shown, a guide limit groove 11 is provided at the lower end of the inner wall of the outer limit block 3 , and a plurality of mounting holes 12 are provided inside the bottom plate 1 , and the mounting holes 12 are provided in cooperation with the horizontal clamp 2 .

[0033] By setting the guide limit groove 11 below the outer limit block 3, it can be matched with the external structure of the aluminum box to be welded, so that the outer wall of the aluminum box can be clamped and fixed in all directions and accurately. At the same time, the setting of the mounting hole 12 can quickly install, disassemble and replace multiple horizontal clamps 2, thereby improving the convenience of using the clamp.

[0034] Example 3

[0035] Embodiment 3 is based on embodiment 1 to improve the positioning accuracy of the aluminum box before welding. Figure 1 and Figure 3-4 As shown, an anti-slip annular groove 13 is provided at the upper end of the outer wall of the positioning pin 10, and the spacings between the plurality of positioning pins 10 are different.

[0036] Since the distances between the multiple locating pins 10 are different, the locating pins 10 can effectively prevent the aluminum box from being fooled, so that the aluminum box can be accurately set in position before welding. At the same time, the setting of the annular groove 13 is slowed down, so that the locating pins 10 can be quickly pulled out after being inserted into the interior, and the situation where the locating pins 10 cannot be pulled out due to interference fit is avoided as much as possible, thereby improving the convenience of operation of the clamp.

[0037] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
