[0037] Combine the following Figure 1 A welding fixture of the present application is described.

[0038] According to the embodiments of the present application, Figure 1 As shown, the welding fixture includes a base plate 1, a support assembly 2 and a fixture. The base plate 1 is provided with at least two first slide rails 11, and the two first slide rails 11 are arranged side by side. The support assembly 2 is installed on the first slide rail 11, and the support assembly 2 can move along the extension direction of the first slide rail 11. The support assembly 2 is used to install the first fixture unit 3. The base plate 1 is formed with a mounting structure 12, and the mounting structure 12 is used to install the second fixture unit 4.

[0039] According to the welding fixture of the embodiment of the present application, the first clamp unit 3 can be installed at the support component 2. At the same time, since the support component 2 can be moved relative to the first slide rail 11, the support component 2 and the clamp at the support component 2 can be moved to a suitable position, thereby ensuring the working effect of the clamp, and the position of the first clamp unit 3 can be adjusted so that the first clamp unit 3 can clamp and fix different workpieces. The support component 2 can also be moved to the edge of the bottom plate 1 along the first slide rail 11, and then the second clamp unit 4 is connected to the mounting structure 12 to achieve the installation connection of the second clamp unit 4 with the bottom plate 1. At this time, the support component 2 is at the edge and will not affect the work of the second clamp unit 4 connected to the mounting structure 12. It should be noted that the second clamp unit 4 connected to the mounting structure 12 can be different from the first clamp unit 3 installed at the support component 2, that is, the bottom plate 1 can be used to install different clamps, which improves the versatility of the welding fixture. The second clamp unit 4 at the mounting structure 12 and the first clamp unit 3 at the support component 2 can be used to clamp and fix different workpieces.

[0040] It is understandable that if Figure 2 As shown, the first clamp unit 3 mounted to the support assembly 2 can move along the first slide rail 11. That is, the position of the first clamp unit 3 can be adjusted, so that workpieces 5 of different sizes and regular shapes can be fixed. Figure 3 As shown, the second clamp unit 4 installed at the mounting structure 12 may be a customized clamp for clamping and fixing a workpiece 5 of a specific shape.

[0041] It can be understood that the second clamp unit 4 connected to the mounting structure 12 realizes a fixed connection with the base plate 1, and the stability of the clamp is better.

[0042] Exemplarily, the thickness of the bottom plate 1 is, for example, greater than 15 mm.

[0043] Exemplarily, the second clamp unit 4 is detachably connected to the mounting structure 12 via a connecting plate.

[0044] In one embodiment of the present application, Figure 1 As shown, the two first slide rails 11 are respectively located at the edges of the two opposite ends of the base plate 1 , and the mounting structure 12 is located between the two first slide rails 11 .

[0045] It can be understood that setting the two first slide rails 11 at the edge of the base plate 1 maximizes the space between the two first slide rails 11, which is beneficial to the setting of the mounting structure 12, can increase the number of mounting structures 12, and improves the number of first clamp units 3 that can be installed on the base plate 1.

[0046] Exemplarily, the first end of the support assembly 2 is slidably connected to one of the first slide rails 11, and the second end of the support assembly 2 is slidably connected to another second slide rail 22. When the first clamp unit 3 at the support assembly 2 is used to limit and fix the workpiece, the support assembly 2 can be moved to the middle of the bottom plate 1; and when the second clamp unit 4 connected to the mounting structure 12 is used to limit and fix the workpiece, the support assembly 2 can be first moved along the second slide rail 22, so that the support assembly 2 moves to the edge, which can prevent the support assembly 2 from affecting the installation and use of the second clamp unit 4.

[0047] Exemplarily, the two first slide rails 11 are located at both ends of the bottom plate 1 in the length direction, and the distance between the first slide rail 11 and the end surface of the bottom plate 1 in the length direction is 30 mm-150 mm.

[0048] In one embodiment of the present application, Figure 1 As shown, the mounting structure 12 includes connection holes 121 , and a plurality of connection holes 121 are evenly distributed on the base plate 1 .

[0049] It is understandable that the second clamp unit 4 can be installed by providing a plurality of connection holes 121 on the bottom plate 1 and inserting fasteners into the connection holes 121 and connecting them to the second clamp unit 4 .

[0050] It is understandable that the second clamp unit 4 can be installed and fixed by using one connection hole 121 or at least two connection holes 121 .

[0051] It is understandable that, since the connection holes 121 are evenly spaced, the connection holes 121 may be numbered to facilitate subsequent positioning and identification.

[0052] Exemplarily, the diameter of the connecting hole 121 is, for example, 20 mm-50 mm.

[0053] In one embodiment of the present application, the mounting structure 12 includes a clamping portion, and a plurality of clamping portions are evenly distributed on the base plate 1 at intervals.

[0054] It can be understood that, by providing a plurality of clamping portions on the bottom plate 1 , each clamping portion can be used to be clamped with the second clamp unit 4 , so that the second clamp unit 4 is mounted on the bottom plate 1 .

[0055] In one embodiment of the present application, Figure 1 As shown, the support assembly 2 includes at least two support plates 21, which are installed on the first slide rail 11. The support plate 21 can move relative to the first slide rail 11. The support plate 21 is provided with a second slide rail 22. The second slide rail 22 is connected with a mounting plate 23. The mounting plate 23 can move relative to the second slide rail 22. The mounting plate 23 can be used to install the first clamp unit 3.

[0056] It can be understood that both support plates 21 can move relative to the first slide rail 11, and mounting plates 23 are provided at the two support plates 21, and the mounting plates 23 can be used to install the first clamp unit 3. By controlling the support plates 21 to move relative to the first slide rail 11 and controlling the mounting plates 23 to move relative to the second slide rail 22, the position of the first clamp unit 3 can be adjusted, so that the first clamp units 3 at the two support plates 21 can clamp and position the workpiece at the same time.

[0057] Exemplarily, the first end of the support plate 21 is slidably connected to one of the first slide rails 11, and the second end of the support plate 21 is slidably connected to the other first slide rail 11. It should be noted that the support plate 21 can also be connected to the first slide rail 11 by a connection method.

[0058] In one embodiment of the present application, an extension direction of the first slide rail 11 and an extension direction of the second slide rail 22 are perpendicular to each other.

[0059] It can be understood that the support plate 21 can move along the first slide rail 11, and the mounting plate 23 can move along the second slide rail 22, and when the support plate 21 and the mounting plate 23 move, they will drive the first clamp unit 3 installed on the mounting plate 23 to move. The extension direction of the first slide rail 11 and the extension direction of the second slide rail 22 are set to be perpendicular to each other, so that the first clamp units 3 at the two support plates 21 can clamp and position workpieces of regular shapes.

[0060] Exemplarily, the two support plates 21 are parallel to each other, and the first clamping units 3 at the two support plates 21 can clamp and position a workpiece of a regular quadrilateral shape.

[0061] In one embodiment of the present application, Figure 1 As shown, the second slide rail 22 is connected to at least two mounting plates 23 .

[0062] It can be understood that at least two mounting plates 23 are connected to the second slide rail 22 of each support plate 21, and the welding fixture has at least four first clamp units 3. By moving the support plate 21 along the first slide rail 11, the distance between the two support plates 21 can be adjusted. By moving the mounting plate 23 along the second slide rail 22, the distance between different mounting plates 23 on the same support plate 21 can be adjusted, thereby realizing the position adjustment of the first clamp unit 3 installed on the mounting plate 23, so that the first clamp units 3 installed on the four mounting plates 23 can clamp and position different positions of the workpiece, thereby improving the stability of the workpiece.

[0063] In one embodiment of the present application, Figure 1As shown, the first clamp unit 3 includes a pushing assembly 31 and a magnetic attraction assembly 32, which are installed on the supporting assembly 2, the pushing assembly 31 is suitable for pushing the side wall surface of the workpiece, and the magnetic attraction assembly 32 is suitable for attracting the workpiece.

[0064] It can be understood that the first clamp unit 3 is installed on the support component 2. When clamping and positioning the workpiece, the workpiece is first placed on the first clamp unit 3. At this time, the magnetic suction component 32 will suck the workpiece to keep the workpiece stable, and then the workpiece is pushed by the pushing component 31. Different pushing components 31 and magnetic suction components 32 cooperate to achieve the clamping and positioning of the workpiece.

[0065] It is understandable that the related art only uses a clamping cylinder to fix the workpiece, which is easily affected by the height of the workpiece. When the height of the workpiece is too high, the height of the clamping cylinder needs to be adjusted to ensure the stability of the workpiece. However, the present application first uses the magnetic suction component 32 to suck and position the workpiece, which is not limited by the height of the workpiece.

[0066] Exemplarily, the support assembly 2 is provided with at least two pushing assemblies 31 , and different pushing assemblies 31 are used to push different positions of the workpiece, so that the workpiece is clamped between different pushing assemblies 31 , thereby achieving clamping and positioning of the workpiece.

[0067] Exemplarily, a limiting structure may be provided at the support assembly 2, which can limit the workpiece. Then, the workpiece is pushed by the pushing assembly 31 so that the workpiece is clamped between the pushing assembly 31 and the limiting structure.

[0068] In one embodiment of the present application, Figure 1 As shown, the magnetic attraction component 32 includes:

[0069] A bottom magnetic member 321, the bottom magnetic member 321 is mounted on the support assembly 2, and the bottom magnetic member 321 is suitable for magnetic attraction with the bottom of the workpiece; and / or,

[0070] The side magnetic member 322 is installed on the supporting assembly 2 , and the side magnetic member 322 is suitable for magnetic attraction with the side wall surface of the workpiece.

[0071] It is understandable that by providing a bottom magnetic suction member to suck the bottom of the workpiece tightly, the workpiece can remain stable when placed on the first clamp unit 3 and will not be affected by the height of the workpiece. When the pushing assembly 31 pushes the workpiece tightly, the bottom magnetic suction member can keep the workpiece tightly sucked, and can prevent the workpiece from changing in height when being pushed by the pushing assembly 31.

[0072] It can be understood that by setting up the side magnetic suction parts, after the pushing assembly 31 pushes the workpiece, the side wall surface of the workpiece will be magnetically attracted to the side magnetic part 322, that is, the side magnetic suction parts can clamp the workpiece, thereby improving the stability of the workpiece, and the clamping force of the side magnetic suction parts on the workpiece can offset the welding stress during the welding of the workpiece, thereby avoiding deformation of the workpiece during the welding process.

[0073] In the embodiment of the present application, the end surfaces of different bottom magnetic members 321 facing away from the support assembly 2 are in the same plane.

[0074] It is understandable that by setting the end faces of different bottom magnetic suction parts to be in the same plane, when the workpiece is placed on the bottom magnetic suction part, it can be ensured that the bottom of the workpiece is in the same horizontal plane, ensuring the subsequent processing effect of the workpiece.

[0075] In an embodiment of the present application, the pushing assembly 31 includes a pushing cylinder, the extension and retraction direction of the pushing cylinder is a first direction, the magnetic surface of the side magnetic part 322 is suitable for magnetic attraction with the workpiece, the direction of the magnetic surface is a second direction, and the first direction and the second direction are perpendicular to each other.

[0076] It can be understood that when the first clamp unit 3 clamps and positions the workpiece, since the magnetic surface of the side magnetic component and the telescopic direction of the pushing cylinder are perpendicular to each other, the pushing cylinder and the side magnetic component can respectively limit the two adjacent side wall surfaces of the workpiece, thereby improving the stability of the workpiece.

[0077] It can be understood that at least four first clamping units 3 can be set, and the four first clamping units 3 are respectively located at four right angles in the positive direction or the long direction. The pushing cylinder and the side magnetic suction part of each first clamping unit 3 can respectively limit the two adjacent side wall surfaces of the workpiece, so that the four right angles of the workpiece will be limited by the pushing cylinder and the side magnetic suction part, thereby ensuring the positioning effect of the workpiece.

[0078] Finally, it should be noted that the above implementation modes are only used to illustrate the present application, rather than to limit the present application. Although the present application is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent substitutions of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application, and should be included in the scope of the claims of the present application.
