Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a positioning tool. Background Art

[0002] In the field of automobile and electric bicycle manufacturing, the frames are generally made of aluminum alloy pipes. During the finishing process of the frame aluminum alloy pipes, the pipes need to be installed on the corresponding molds and processed at the corresponding processing stations.

[0003] Before processing the pipe fittings, they need to be positioned. In the prior art, a common method is to place the pipe fittings with the mold installed between two profiling clamps, one of which remains stationary while the other moves and squeezes the pipe fittings, so that the two profiling clamps clamp the pipe fittings together, thereby achieving the positioning effect of the pipe fittings. However, when the pipe fittings are cut or processed, the processing equipment applies external force to the pipe fittings, which may cause the pipe fittings to move displaced relative to the profiling clamps. This will cause the size of the milled round and waist-shaped holes to be too large or the shape after processing to be irregular, affecting the quality of pipe fitting processing.

[0037] In this embodiment, the pipe fitting 51 is installed on the mold 52 during the processing, and when positioning is performed, the pipe fitting 51 and the mold 52 perform the positioning work together.

[0038] In this embodiment, when the positioning tool is used, the pipe 51 and the mold 52 are first installed, and then the pipe 51 is placed between the two clamping parts 21 of the clamping assembly 2, and the pipe 51 is moved so that one end of the pipe 51 in the axial direction thereof abuts against the abutting positioning plate 31, and then the clamping drive member works to drive the two clamping parts 21 to approach each other and clamp the pipe 51 together. Under the joint action of the two clamping parts 21 and the abutting positioning plate 31, the pipe 51 can be reliably and stably positioned, and when the pipe 51 is subsequently processed, the misalignment of the pipe 51 due to the pressure applied by the processing equipment to the pipe 51 can be avoided, thereby effectively ensuring the processing quality of the pipe 51.

The first end of the clamping rod 211 is arranged on the clamping driving member, and the positioning clamping block 212 is fixed to the second end of the clamping rod 211. The clamping driving member can drive the two clamping rods 211 to approach each other so that the two positioning clamping blocks 212 can jointly clamp the pipe 51.

[0040] In this embodiment, the clamping drive member is configured as a finger cylinder 22, which includes a first cylinder body 221 and two movable finger claws 222 disposed on the first cylinder body 221.
