Description

Technical Field

[0001] The invention relates to a positioning tool, in particular to a fastening ring positioning device for robot welding. Background Art

[0002] The fastening ring needs to be welded into a whole with the workpiece made of plate by a welding robot. During welding, the fastening ring and the workpiece need to be positioned by a positioning tool to ensure the welding quality.

[0003] The existing positioning fixtures for positioning the fastening ring are arranged separately and in an array on the mounting plate. The distance between the positioning fixtures is large, and few positioning fixtures can be set on one mounting plate, resulting in low welding efficiency. Since the fastening ring and the workpiece need to be welded on both sides, the operator needs to flip it after welding one side. The distance between the positioning fixtures is large, which is inconvenient for the operator to operate, resulting in low welding efficiency. Summary of the invention

[0004] In view of this, the present invention provides a fastening ring positioning device for robot welding, which solves the problem of low welding efficiency caused by unreasonable layout of fastening ring positioning tooling.

[0005] To this end, the present invention provides a fastening ring positioning device for robot welding, including a mounting plate, on which are provided a plurality of positioning mechanisms arranged in an array, the positioning mechanisms including a clamping mechanism and two placement racks, the clamping mechanism including two clamping devices arranged back to back, the two placement racks being arranged on both sides of the clamping mechanism, the fastening ring and the workpiece to be welded being placed on the placement racks, and the clamping device pressing the fastening ring onto the placement racks.

[0006] Furthermore, the clamping device is a push-pull clamp, and the end of the transmission rod of the push-pull clamp is against the surface of the fastening ring.

[0007] Furthermore, the clamping mechanism also includes a clamp seat, and the clamping device is fixedly mounted on the clamp seat.

[0008] Furthermore, the clamp seat includes two parallel arranged "J" shaped clamp seat units, the clamping device is fixedly mounted on the N-shaped body of the clamp seat unit, and connecting plates are arranged at opposite ends of the N-shaped body, and the connecting plates are fixedly mounted on the mounting plate.

[0009] Furthermore, the placement rack includes two parallel supported plates and a blocking device, the fastening ring is placed in the arc groove of the supported plate, one side of the fastening ring is against the blocking device, the part to be welded is placed on the supported plate, and the reinforcement plate of the part to be welded is clamped between the two supported plates, and the distance between the two supported plates is equal to the thickness of the reinforcement plate.

[0010] Furthermore, the blocking device comprises two baffles arranged in parallel, and the side surfaces of the fastening ring abut against the side edges of the baffles.

[0011] Further, the distance between the two baffles is smaller than the diameter of the fastening ring.

[0012] Furthermore, the two baffles are fixedly connected via a connecting plate.

[0013] The present invention provides a fastening ring positioning device for robot welding, wherein a clamping mechanism and two placement racks form a positioning mechanism, and two rows of positioning mechanisms are arranged on a mounting plate, and a row of positioning mechanisms has a plurality of positioning mechanisms arranged in parallel. When positioning the fastening ring and the workpiece, the placement racks on both sides of the clamping mechanism are used to weld the front connection between the two and the other to weld the back connection between the two, so that the welding robots on both sides of the mounting plate can be staggered and welded at the same time, thereby improving the welding efficiency. The fastening rings on the two rows of positioning mechanisms are arranged symmetrically facing each other, thereby reducing the travel of the welding robot during welding and improving the welding efficiency. The positioning mechanism formed by the combination of two push-pull clamps and two placement racks has a compact structure. On the one hand, the space utilization rate of the mounting plate is high, more fastening rings can be welded at the same time, thereby improving the welding efficiency. On the other hand, the operator can turn over the two fastening rings without moving, thereby improving the efficiency. The specific positioning method of the fastening ring and the workpiece to be welded is as follows: the fastening ring is placed on two supporting plates, and the transmission rod of the push-pull clamp presses the fastening ring against the blocking device to fully position the fastening ring; first weld the fastening ring and the side of the workpiece to be welded without the reinforcement plate, at this time the workpiece to be welded is placed on the two supporting plates, the bottom of the workpiece to be welded is against the fastening ring, and the back reinforcement plate is restricted by the two supporting plates for welding. After one side is welded, repeat the above action to weld the other side.

[0014] The invention provides a fastening ring positioning device for robot welding, which has a firm fastening ring positioning and high welding quality and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention provides a fastening ring positioning device for robot welding, wherein a clamping mechanism and two placement racks form a positioning mechanism, and two rows of positioning mechanisms are arranged on a mounting plate, and a row of positioning mechanisms has a plurality of positioning mechanisms arranged in parallel. When positioning the fastening ring and the workpiece, the placement racks on both sides of the clamping mechanism are used to weld the front connection between the two and the other to weld the back connection between the two, so that the welding robots on both sides of the mounting plate can be staggered and welded at the same time, thereby improving the welding efficiency. The fastening rings on the two rows of positioning mechanisms are arranged symmetrically facing each other, thereby reducing the travel of the welding robot during welding and improving the welding efficiency. The positioning mechanism formed by the combination of two push-pull clamps and two placement racks has a compact structure. On the one hand, the space utilization rate of the mounting plate is high, more fastening rings can be welded at the same time, thereby improving the welding efficiency. On the other hand, the operator can turn over the two fastening rings without moving, thereby improving the efficiency. The specific positioning method of the fastening ring and the workpiece to be welded is as follows: the fastening ring is placed on two supporting plates, and the transmission rod of the push-pull clamp presses the fastening ring against the blocking device to fully position the fastening ring; first weld the fastening ring and the side of the workpiece to be welded without the reinforcement plate, at this time the workpiece to be welded is placed on the two supporting plates, the bottom of the workpiece to be welded is against the fastening ring, and the back reinforcement plate is restricted by the two supporting plates for welding.

The N-shaped main body 2211 is provided with connecting plates 2212 at opposite ends, and the connecting plates 2212 are fixedly installed on the mounting plate 1.

[0031] The push-pull clamp is fixedly installed on the "J"-shaped clamp seat unit, which is convenient for adjusting the installation position of the push-pull clamp and ensuring the positioning effect of the fastening ring.
