For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] See Figures 1 to 4 The present invention provides a welding positioning device, comprising: a tooling body 100, the bottom surface of which is a first plane 101, and the upper part of the tooling body 100 is provided with a mounting groove with a side opening. The mounting groove is arranged parallel to the first plane 101 for detachably mounting a bracket 10 to be welded. The first plane 101 can slide along the placement plane 21 so that two adjacent side walls of the bracket 10 respectively abut against two inner side walls at a right angle position of the lower battery housing frame 20.

[0031] When the thin-plate bracket 10 needs to be welded to the preset position of the lower battery housing frame 20, first install the bracket 10 in the mounting groove so that a part of the bracket 10 protrudes from the side opening of the mounting groove. Place the first plane 101 on the placement plane 21 and slide it until the two adjacent side walls of the bracket 10 are respectively held against the two inner side walls of the lower battery housing frame 20 at a right angle. Then weld and fix the bracket 10 to the position where it contacts the lower battery housing frame 20. Then remove the bracket 10 from the mounting groove. The welding positioning device with the above structure can accurately and stably position the bracket 10 at the preset height position, avoiding the bracket 10 from moving or tilting, thereby ensuring the welding quality.

[0032] It should be noted that during welding, the worker needs to grasp the main body 100 of the tooling and move it towards a right angle position towards the lower battery housing frame 20, so that the bracket 10 extends out of the two adjacent side walls of the mounting groove and presses against the two inner side walls at the right angle position, strictly controlling the welding gap of the bracket 10, while also keeping the bracket 10 horizontally placed. The height positions of the main body 100 of the tooling and the mounting groove on the main body 100 are configured according to the height of the placement plane 21. In this embodiment, one profile of the lower battery housing frame 20 has a support plate for supporting the battery, and the upper surface of the support plate constitutes the placement plane 21.

[0033] See Figure 2 , Figure 3 and Figure 4 In some embodiments of this utility model, a pressure plate 300 is detachably connected to the upper surface of the tooling body 100. The lower surface and one side surface of the pressure plate 300 are recessed inward to form a contoured groove 310. The contoured groove 310 and the upper surface of the tooling body 100 define a mounting groove for clamping the bracket 10. The contoured groove 310 is consistent with a portion of the outline shape of the bracket 10 to restrict the movement of the bracket 10 relative to the pressure plate 300. It should be noted that if the bracket 10 is inserted and pulled out along the side opening of the mounting groove to achieve detachable installation, the height dimension of the mounting groove needs to be consistent with the thickness dimension of the bracket 10 to ensure that the bracket 10 will not loosen during the welding process. This requires high precision, and after the bracket 10 is welded, jamming may easily occur when pulling out the bracket 10. By using the contoured groove 310 of the pressure plate 300 to cooperate with the upper surface of the tooling body 100 to clamp the bracket 10, it can be ensured that the bracket 10 will not loosen. After removing the pressure plate 300, the bracket 10 and the tooling body 100 can be separated smoothly.

[0034] See Figure 2 and Figure 3In some embodiments of this utility model, the pressure plate 300 is vertically perforated by a first guide hole 320 and a bolt hole 330. The upper part of the tooling body 100 is correspondingly provided with a second guide hole 102 coaxial with the first guide hole 320 and a threaded hole 103 coaxial with the bolt hole 330. A guide post 400 passes between the first guide hole 320 and the second guide hole 102. A fastening screw 500 passes through the bolt hole 330 and connects to the threaded hole 103. Using this structure to install the pressure plate 300 on the tooling body 100 prevents the pressure plate 300 from deflecting. Furthermore, the bracket 10 can be pulled out from between the pressure plate 300 and the tooling body 100 simply by loosening the fastening screw 500, without completely removing the pressure plate 300.

[0035] See Figure 4 In some embodiments of this utility model, the inner peripheral wall of the contoured groove 310 includes an arc surface 311 and a first positioning surface 312 and a second positioning surface 313 respectively connected to the two ends of the arc surface 311, wherein the first positioning surface 312 and the second positioning surface 313 are perpendicular to each other. It can be understood that when the outer contour of the bracket 10 has an arc segment corresponding to the arc surface 311, the first positioning surface 312 and the second positioning surface 313 can prevent the bracket 10 from rotating relative to the contoured groove 310, thereby ensuring the accuracy of the welding position.

[0036] See Figure 2 In some embodiments of this utility model, the tooling body 100 has a first positioning sidewall 104 and a second positioning sidewall 105 that are orthogonal to each other. The first positioning sidewall 104 and the second positioning sidewall 105 can respectively abut against two mutually perpendicular inner sidewalls of the lower battery housing frame 20, so that the bracket 10 is in a preset welding position. It should be noted that when the first positioning sidewall 104 and the second positioning sidewall 105 abut against two mutually perpendicular inner sidewalls of the lower battery housing frame 20, the two adjacent sidewalls of the bracket 10 extending from the mounting groove abut against two inner sidewalls at a right angle position of the lower battery housing frame 20, preventing excessive force from pressing on the bracket 10 and causing deformation.

[0037] See Figure 2 and Figure 3 In some embodiments of this utility model, the side of the tooling body 100 is provided with a handle 600 extending along the depth direction away from the mounting groove. It is understood that a worker uses one hand to grasp the handle 600 to move the tooling body 100 into position, and the other hand to hold the welding tool to weld the bracket 10. The handle 600 helps prevent the worker's hand from getting too close to the welding position and potentially getting injured.

[0038] In some embodiments of this utility model, in order to adjust the welding height of the bracket 10, the height of the tooling body 100 is adjustable to adjust the height position of the mounting groove.

[0039] In some embodiments of this utility model, the tooling body 100 is made of magnetic material, and at least one magnetic pad is adsorbed and installed on the bottom surface of the tooling body 100. It is understood that the overall height of the tooling body 100 can be adjusted by replacing magnetic pads of different thicknesses or by adding or removing different numbers of magnetic pads, thereby adjusting the height position of the mounting slot, making operation very convenient.

[0040] See Figure 5 In some embodiments of this utility model, the tooling body 100 includes a lower seat 110 and an upper seat 120. The lower seat 110 has an upwardly penetrating lifting channel 111 inside. The upper seat 120 has a guide slider 121 that can slide up and down along the lifting channel 111. The side of the lower seat 110 has a threaded channel 112 that communicates with the lifting channel 111. The lower end of the guide slider 121 has a driving inclined surface 122 that slopes upward toward the threaded channel 112. The threaded channel 112 is threadedly connected to an adjusting screw 700. One end of the adjusting screw 700 extends out of the lower seat 110, and the other end of the adjusting screw 700 pushes against the driving inclined surface 122 to make the upper seat 120 move up and down relative to the lower seat 110. Understandably, when the adjusting screw 700 rotates to move towards the lifting channel 111, one end of the adjusting screw 700 pushes against the driving inclined surface 122, causing the guide slider 121 and the upper seat 120 to move upward together, thereby raising the height of the mounting slot on the upper seat 120; when the adjusting screw 700 rotates to retract away from the lifting channel 111, the driving inclined surface 122 remains in contact with one end of the adjusting screw 700, causing the guide slider 121 and the upper seat 120 to move downward together, thereby lowering the height of the mounting slot on the upper seat 120.

[0041] See Figure 5 In some embodiments of this utility model, in order to ensure that the length dimension of the tooling body 100 can be stable, a plurality of tension springs 800 arranged around the lifting channel 111 are provided between the lower seat 110 and the upper seat 120. The tension springs 800 drive the driving inclined surface 122 to remain against the end of the adjusting screw 700.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
