If you want to check the coil, you need to move the positioning fixture, which is very inconvenient. Therefore, the market needs a new device to solve the current problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for coil spot welding, comprising a weighted base plate, a storage groove sleeved on the upper end of the weighted base plate at an inner position, a longitudinal support fixed at a vertical angle on the upper end of the weighted base plate at a left position, a plurality of threaded holes A distributed at the front end of the longitudinal support, a sliding groove provided at the right end of the longitudinal support, a sleeve plate sleeved on the inner position of the sliding groove, and a stainless steel bolt A rotatably installed on the inner side of the threaded hole A, the stainless steel bolt A passing through the threaded hole A and entering the through hole on the inner side of the sleeve plate;
[0006] The longitudinal support is fitted with a transverse support at the right end via a connecting plate. A through groove is provided at the upper end of the transverse support, and a square post is fitted inside the through groove. A gear groove is provided inside the square post, and a gear shaft is fitted inside the gear groove. A handle is fixed at the upper end of the gear shaft, and a fixing post for winding a coil is fixed at the upper end of the handle. A threaded hole C is provided at the lower end of the square post, and a bolt post is provided inside the threaded hole C. When the bolt post enters the threaded hole C, the rubber plate at the lower end of the bolt post is tightly pressed against the lower end of the transverse support.
[0007] Preferably, the upper end of the socket plate is provided with a slot, and the front end of the socket plate is provided with a threaded hole B. The socket plate is installed with the transverse bracket through the slot and the threaded hole B.
[0008] Preferably, the horizontal bracket inserts the slot at the lower left position to the socket plate, so that the socket plate is inserted into the inside of the slot, and the fixing block fixed inside the slot is engaged inside the slot. The front end of the horizontal bracket is provided with a through hole at the left position. When the socket plate is inserted into the inside of the slot, the through hole is aligned with the center of the threaded hole B.
[0009] Preferably, a stainless steel bolt B is inserted into the inner position of the circular hole, and the stainless steel bolt B is inserted into the inner position of the circular hole. By rotating it, it enters the inner position of the threaded hole B, and the transverse bracket is installed at the right end of the longitudinal bracket.
[0010] Preferably, the stainless steel bolt A is moved out from the inside of the threaded hole A, causing the socket plate to move up and down along the slide groove. The front end of the socket plate is provided with a through hole at the upper left position. When the stainless steel bolt A is rotated to the position where it is fully inserted into the inside of the threaded hole A, it can be inserted into the through hole of the socket plate. The stainless steel bolt A entering the through hole keeps the socket plate at its current height.
[0011] Preferably, the handle controls the rotation of the fixed column by manual operation. When the handle rotates, it rotates around the gear shaft as the central axis.

[0013] Preferably, a coil is wound around the outer wall of the fixed column, and the storage slot is inserted into the weighted base plate.
[0014] Compared with the prior art, this utility model provides a positioning fixture for coil spot welding, which has the following beneficial effects:
[0015] 1. After the coil is wound onto the fixed post, when inspecting each area of the coil, the handle can be turned to rotate the fixed post. The rotation of the handle causes the gear shaft to rotate inside the gear groove. At the same time, when the rubber plate is rotated, it creates a certain distance between itself and the horizontal support. The square post can then move laterally through the groove. After adjusting to the appropriate angle, the rubber plate is rotated in the opposite direction to make it fit tightly against the lower end of the horizontal support. This method allows for flexible adjustment and makes it easy for operators to check the position of the solder joints.
[0016] 2. The longitudinal support is installed with the transverse support via a socket plate. Before installation, the height of the socket plate can be adjusted. After adjusting the socket plate to a suitable height, insert the stainless steel bolt A into the corresponding threaded hole A and into the through hole of the socket plate. The through hole of the socket plate is located on the upper left side of its front end, and a slot is provided on the upper part of the socket plate. When installing the transverse support, insert the socket plate into the slot and make the fixing block enter the slot. At this time, align the round hole with the threaded hole B, insert the stainless steel bolt B into the round hole, and rotate the stainless steel bolt B to enter the threaded hole B. This completes the height adjustment of the transverse and longitudinal supports. This method ensures the stability of the transverse support during installation and height adjustment.
[0017] 3. This device has a storage slot fitted inside the weighted base plate. The storage slot is inserted into the weighted base plate and is located below the fixed column. This allows impurities that fall during spot welding to enter the storage slot. After spot welding is completed, the storage slot can be removed and the impurities inside can be cleaned, which saves time. Attached Figure Description
