Description

Technical Field

[0001] This utility model relates to the technical field of battery tray processing equipment, and in particular to a crossbeam positioning and welding fixture for battery tray processing. Background Technology

[0002] In the battery tray production process, the crossbeam needs to be precisely welded to the tray body to ensure structural strength. Traditional tooling typically uses a single clamping mechanism, which suffers from problems such as unstable positioning, cumbersome operation, and welding deformation, resulting in a low finished product yield. Furthermore, existing equipment struggles to simultaneously fix the tray and crossbeam, requiring multiple adjustments and impacting processing efficiency. Therefore, a multi-directional clamping, precise positioning, and easy-to-operate welding tooling is needed. Utility Model Content

[0003] (1) Technical solution

[0004] To solve the above-mentioned technical problems, this utility model provides a crossbeam positioning and welding fixture for battery tray processing, including a frame, a first clamping mechanism, a high-strength welding clamping cylinder, a clamping arm, a second clamping mechanism, a third clamping mechanism, a clamping plate, and a handle. The frame has several first clamping mechanisms for clamping the battery tray on its four edges. The high-strength welding clamping cylinder is installed on both sides of the frame. The clamping arm of the high-strength welding clamping cylinder is equipped with a second clamping mechanism for clamping the end of the crossbeam and a third clamping mechanism for clamping the top of the crossbeam. The clamping plate is provided on both sides of the end of the clamping arm away from the high-strength welding clamping cylinder, and the handle is provided on the top of the clamping arm.

[0005] Preferably, the first clamping mechanism includes a first rotary clamping cylinder, a first piston rod, and a first clamping arm. The first piston rod of the first rotary clamping cylinder is arranged facing upward and its upper end is connected to the bottom of one end of the first clamping arm. The angle between the first clamping arm and the first piston rod is 90°.

[0006] Preferably, the second clamping mechanism includes a second rotary clamping cylinder, a second clamping arm, a first clamping block, and a first limiting plate. The second rotary clamping cylinder is mounted on the clamping arm, and one end of the piston rod away from the cylinder body is connected to one end of the second clamping arm. The other end of the second clamping arm is connected to one end of the first clamping block. When the second rotary clamping cylinder is in the clamping state, the other end of the first clamping block contacts one side of the end of the crossbeam. The first limiting plate is vertically downward on the side of the clamping arm corresponding to the other side of the end of the crossbeam.

[0007] Preferably, the third clamping mechanism includes a third rotary clamping cylinder, a third clamping arm, a second clamping block, and a second limiting plate. The third rotary clamping cylinder is mounted on the top of the clamping arm, and the end of the piston rod away from the cylinder body is connected to one end of the third clamping arm. The other end of the third clamping arm is connected to one end of the second clamping block. When the third rotary clamping cylinder is in the clamping state, the other end of the second clamping block is in contact with one side of the top of the crossbeam. The second limiting plate is vertically downward on the side of the clamping arm corresponding to the other side of the top of the crossbeam.

[0008] Preferably, the bottom of the frame is provided with rollers.

[0009] (2) Beneficial effects

[0010] This utility model provides a crossbeam positioning and welding fixture for battery tray processing. Compared with the prior art, this utility model has the following advantages:

[0011] 1. Multi-directional clamping: Through the coordinated action of the first, second and third clamping mechanisms, the pallet and the crossbeam are positioned simultaneously at multiple points. This not only achieves stable positioning and avoids welding deformation, but also simplifies operation and greatly improves work efficiency and product qualification rate.

[0012] 2. Precise positioning: The positioning plate and clamping block work together to reduce the positional error of the crossbeam.

[0013] 3. Modular design: Each mechanism is independently controlled, which facilitates maintenance and replacement. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0019] like Figures 1-3 As shown, the present invention discloses a crossbeam positioning and welding fixture for battery tray processing, comprising a frame 1, a first clamping mechanism 2, a high-strength welding clamping cylinder 5, a clamping arm 6, a second clamping mechanism 7, a third clamping mechanism 8, a clamping plate 9, and a handle 10. The frame 1 has several first clamping mechanisms 2 for clamping battery trays 3 on its four edges. The high-strength welding clamping cylinder 5 is installed on both sides of the frame 1. The clamping arm 6 of the high-strength welding clamping cylinder 5 is equipped with a second clamping mechanism 7 for clamping the end of the crossbeam 4 and a third clamping mechanism 8 for clamping the top of the crossbeam 4. The clamping plate 9 is provided on both sides of the clamping arm 6 away from the high-strength welding clamping cylinder 5, and the handle 10 is provided on the top of the clamping arm 6.

[0020] The first clamping mechanism 2 includes a first rotary clamping cylinder 21, a first piston rod 22, and a first clamping arm 23. The first piston rod 22 of the first rotary clamping cylinder 21 is arranged facing upward and its upper end is connected to the bottom of one end of the first clamping arm 23. The angle between the first clamping arm 23 and the first piston rod 22 is 90°. During operation, the cylinder 21 pushes the piston rod 22 upward, which drives the clamping arm 23 to rotate horizontally and press the edge of the tray to ensure that the tray is stable.

[0021] The second clamping mechanism 7 includes a second rotary clamping cylinder 71, a second clamping arm 72, a first clamping block 73, and a first limiting plate 74. The second rotary clamping cylinder 71 is mounted on the clamping arm 6, and one end of the piston rod away from the cylinder body is connected to one end of the second clamping arm 72. The other end of the second clamping arm 72 is connected to one end of the first clamping block 73. When the second rotary clamping cylinder 71 is in the clamping state, the other end of the first clamping block 73 is in contact with one side of the end of the crossbeam 4. The first limiting plate 74 is vertically downward on one side of the clamping arm 6 above the other side of the end of the crossbeam 4. When the second rotary clamping cylinder 71 is activated, the first clamping block 73 abuts against one side of the end of the crossbeam 4, and at the same time, the first limiting plate 74 on the clamping arm 6 presses vertically downward on the other side of the crossbeam, realizing bidirectional positioning of the end.

[0022] The third clamping mechanism 8 includes a third rotary clamping cylinder 81, a third clamping arm 82, a second clamping block 83, and a second limiting plate 84. The third rotary clamping cylinder 81 is mounted on the top of the clamping arm 6, with one end of the piston rod away from the cylinder body connected to one end of the third clamping arm 82. The other end of the third clamping arm 82 is connected to one end of the second clamping block 83. When the third rotary clamping cylinder 81 is in the clamping state, the other end of the second clamping block 83 contacts one side of the top of the crossbeam 4. The second limiting plate 84 is vertically positioned downwards on one side of the clamping arm 6 above the other side of the top of the crossbeam 4. When the third rotary clamping cylinder 81 is activated, the second clamping block 83 abuts against one side of the top of the crossbeam 4, while the second limiting plate 84 on the clamping arm 6 presses vertically downwards against the other side of the crossbeam, achieving bidirectional positioning at the top. The bottom of the frame 1 is equipped with rollers 11 for easy movement of the tooling, and the rollers 11 are equipped with brakes.

[0023] Working principle: Place the battery tray 3 on the frame 1, start the first clamping mechanism 2 to clamp the battery tray 3 around its perimeter; adjust the position of the clamping arm 6 by using the handle 10 so that the crossbeam 4 is pre-placed inside the two clamping plates 9; the high-power welding clamping cylinder 5 pushes the clamping arm 6 to move towards the crossbeam 4 to press down on the crossbeam 4; the second and third rotary clamping cylinders 71 and 81 move synchronously to drive the first clamping block 73 and the second clamping block 83 to clamp the end and top of the crossbeam 4 respectively; after welding is completed, each cylinder is reset and the finished product is removed.

[0024] The embodiments described above are merely preferred embodiments of the present invention, and are described in a relatively specific and detailed manner. However, the present invention is not limited to these embodiments. It should be noted that for those skilled in the art, any improvements made without departing from the spirit of the present invention fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
