Description

[0002] With the popularization of new energy vehicles, the importance of the battery system, which accounts for nearly half of the price of electric vehicles, is self-evident. The battery system has a complex structural design.

At the same time, in order to protect the battery from being bumped, the battery is generally loaded in the battery box. However, the production capacity of the battery system is low and the price is expensive, and part of the reason is caused by the complex structural design of the box.

[0027] The following will further elaborate on the embodiments of a positioning device for welding the tray of an automotive battery housing in conjunction with the attached Figures 1-5 drawings.

[0028] A positioning device for welding the tray of an automotive battery housing, as Figure 1 shown in 2 , includes a workbench 1. A dual-axis drive mechanism 2 that moves along the length direction of the workbench 1 is arranged on the workbench 1. A rectangular fixed frame 3 is slidably connected to the dual-axis drive mechanism 2. A plurality of tooling fixtures 4 for clamping and fixing the workpiece 6 to be welded are connected to the rectangular fixed frame 3. The tooling fixture 4 includes a clamping cylinder 41 for clamping and fixing the corners of the workpiece 6 to be welded, an adjustment bar 42 for adjusting the clamping position, and a clamping block 43 for clamping and limiting the internal structure of the workpiece. The clamping cylinders 41 are equidistantly and fixedly connected to the four corners of the rectangular fixed frame 3. A plurality of the adjustment bars 42 are arranged in a square shape within the rectangular fixed frame 3, and both ends of the adjustment bar 42 are movably connected to the rectangular fixed frame 3. The clamping block 43 is arranged in the area enclosed by two adjacent adjustment bars 42, and a clamping groove 431 for accommodating the internal structure of the workpiece 6 to be welded is provided on the clamping block 43.

[0029] Specifically, when the workpiece to be welded 6 (the tray of the automotive battery housing) is being welded, first place the welding workpiece on the workbench 1. After installing the structure to be welded inside it in place, use the biaxial drive mechanism 2 to move along the length direction of the workbench 1 so that the biaxial drive mechanism 2 covers the workpiece to be welded 6. Then use the tooling fixture 4 to clamp and position the internal structure of the workpiece to be welded 6 to facilitate the welding equipment to carry out the welding work. Among them, the clamping cylinder 41 can quickly fix and limit the four corners of the workpiece to be welded 6, and by using the adjusting bar 42 to adjust the position of the clamping block 43, it can further clamp and fix the internal structure of the workpiece to be welded 6, thus avoiding the problem of manual clamping and positioning by workers and the problem of inaccurate positioning easily occurring during the welding process due to deviation.

[0030] In this embodiment, as Figure 2 shown, the biaxial drive mechanism 2 includes a mounting seat 21, a linear slide rail 22, and a drive motor 23. One side of the mounting seat 21 is fixed to the workbench 1 by bolts, and the other side is fixedly connected to the linear slide rail 22. The drive motor 23 is arranged at one end of the linear slide rail 22, and the drive motor 23 is in transmission connection with the linear slide rail 22.

[0031] Specifically, the biaxial drive mechanism 2 includes a mounting seat 21, a linear slide rail 22, and a drive motor 23. One side of the mounting seat 21 is fixed to the workbench 1 by bolts, and the other side is fixedly connected to the linear slide rail 22. The drive source is arranged at one end of the linear slide rail 22, and the drive motor 23 is in transmission connection with the linear slide rail 22. Among them, in addition to being driven by the drive motor 23, a cylinder or an electric cylinder can also be selected for driving, and during the driving process, the speed of its sliding in the biaxial drive mechanism 2 can be adjusted according to the welding position of the workpiece.

[0032] Specifically, the biaxial drive mechanism 2 can control the adjustment of the adjusting bar 42 along the position of the workpiece to be welded 6, so that it is convenient for the positioning device to change according to the welding position, quickly complete the clamping and positioning of the workpiece to be welded 6, and thus improve the welding efficiency.

[0033] In this embodiment, as Figures 3 to 5 shown, the adjusting bar 42 includes a horizontal bar 421 arranged along the length direction of the rectangular fixed frame 3 and a vertical bar 422 arranged along the width direction of the rectangular fixed frame 3. Both ends of the horizontal bar 421 are connected to the rectangular fixed frame 3, both ends of the vertical bar 422 are connected between the horizontal bars 421, and strip-shaped grooves 423 are opened on the peripheral side walls of the vertical bar 422 and the horizontal bar 421.

[0034] Specifically, the adjusting bar 42 is a plate-like structure with a plurality of strip grooves 423 formed on its surface, and both ends of the adjusting bar 42 are slidably connected to the rectangular fixing frame 3, so that the adjusting bar 42 can move along the rectangular fixing frame 3. Furthermore, the position of the clamping block 43 can be adjusted according to the internal structure of the workpiece 6 to be welded. At the same time, the clamping block 43 is slidably connected in the strip grooves 423 of the horizontal bar 421 and the vertical bar 422, making it convenient for the operator to move the clamping block 43 according to the internal structure of the workpiece 6 to be welded, and using the clamping block 43 to clamp and position the workpiece, thereby assisting the welding equipment in positioning and clamping, ensuring that the position to be welded is always firmly fixed during the welding process, and thus improving the welding efficiency.

[0035] In order to quickly position the workpiece 6 to be welded, first, one end of the clamping cylinder 41 is provided with a cylinder fixing seat 411 fixed at the corner of the rectangular fixing frame 3, and then the output end of the clamping cylinder 41 is drivingly connected to the pressing block 412. The pressing block 412 abuts against the four corners of the workpiece 6 to be welded, thus quickly completing the positioning and fixing the position of the workpiece 6 to be welded, avoiding the problem that it shifts during the welding process and deteriorates the welding effect.

[0036] In this embodiment, a working panel 11 is provided at the top of the workbench 1. A plurality of mounting holes 111 are evenly formed on the working panel 11, and the peripheral part of the working panel 11 extends downward to the side wall of the workbench 1. The extended part of the working panel 11 is also evenly provided with a plurality of mounting holes 111.

[0037] Specifically, in order to facilitate the installation of each component, a working panel 11 is provided on the workbench 1, and a plurality of mounting holes 111 are evenly formed on the working panel 11. The mounting holes 111 are round holes, so that the double-shaft transmission mechanism 2 can be fixed on the workbench 1 through the mounting holes 111, and the installation position of the double-shaft transmission mechanism 2 can be changed according to the production requirements and the size specifications of the workpiece 6 to be welded.

[0038] The working principle of the present utility model:

[0039] When welding the workpiece 6 to be welded, place it on the working platform. Use the biaxial drive mechanism 2 to move according to the position of the workpiece 6 to be welded, so that the tooling fixture 4 is moved to a position directly above the workpiece 6 to be welded. First, position the four corners of the workpiece 6 to be welded through the clamping cylinder 41. After fixing its position, manually move the adjustment bar 42 to make it parallel to the internal structure of the workpiece 6 to be welded. Then, control the clamping block 43 to abut and clamp the internal structure of the workpiece 6 to be welded, thus completing the clamping and positioning for convenient welding. By setting the biaxial drive mechanism 2 on the workbench 1, the position of the tooling fixture 4 is adjusted according to the internal structure of the workpiece welding. The four corners of the workpiece are positioned by the clamping cylinder 41, and then the position of the clamping block 43 is further adjusted through the adjustment bar 42, so that it can be positioned and clamped for the internal structure of the workpiece to be welded, thus avoiding the problem of manual positioning welding, improving the accuracy of welding positioning, and also improving the welding effect.

The same components are represented by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
