Description

Positioning tool for parts with complex shapes Technical Field The utility model relates to the technical field of positioning tools, in particular to a positioning tool for parts with complex shapes. Background In modern manufacturing industry, with the diversification of product functions and the complicating of structures, the application of parts with complex shapes is increasingly wide. These parts often have irregular curved surfaces, special raised or recessed structures, and in the process of machining and manufacturing, accurate positioning tools are required to ensure machining precision and product quality. However, most of the existing positioning tools are designed aiming at parts with regular shapes, and have a plurality of defects when processing parts with complex shapes. On the one hand, the shape of the positioning end of the traditional tool is fixed, if the positioning end is required to be matched with parts with different shapes, the tool parts are usually required to be replaced or modified, the operation is complex, the time consumption is long, the production cost is increased, on the other hand, the traditional tool is difficult to accurately adjust the positioning supporting point in the face of the various shapes of complex parts, the positioning efficiency of the parts is low, and positioning deviation is easy to occur. Disclosure of utility model The utility model aims to solve the defects in the prior art, and provides a positioning tool for a part with a complex appearance. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The positioning tool for the parts with the complex shapes comprises a positioning platform and supporting pieces, wherein the supporting pieces are arranged at the top ends of the positioning platform, two supporting pieces are oppositely arranged, and one side of each supporting piece is provided with an adjustable positioning mechanism; The positioning mechanism comprises clamping pieces, two clamping pieces are arranged, one end of each clamping piece is rotatably provided with a sliding block, a control mechanism used for controlling the rotation and stopping of each clamping piece is arranged between each sliding block and each clamping piece, each sliding block is slidably arranged on the inner wall of each sliding groove, each sliding groove is formed in the side wall of each supporting piece, each sliding block penetrates through a screw rod, and the sliding blocks are symmetrically arranged on the outer wall of each screw rod. Further, the control mechanism comprises a rotating shaft, the rotating shaft is embedded in the inner wall of the clamping piece and penetrates through the sliding block to be arranged above the sliding block, a ratchet wheel is arranged on the outer wall of the rotating shaft above the sliding block, the rotating shaft is connected with the ratchet wheel and the sliding block in a sliding mode, a pawl is arranged on one side of the ratchet wheel, a supporting seat is installed on one side, far away from the ratchet wheel, of the pawl in a rotating mode, the supporting seat is fixedly installed on the top end of the sliding block, and a spring is arranged between the side wall of the supporting seat and the side wall of the pawl. Further, the screw threads on the outer wall of the screw rod are opposite in direction and symmetrical about the midpoint of the supporting piece. Further, one side of the clamping piece is provided with anti-skid patterns. Further, a second handle is arranged at the top end of the pawl. Further, one end of the screw rod penetrates through the sliding groove and extends to one side of the supporting piece, and a first handle is fixedly arranged at the end of the screw rod. The positioning tool for the parts with complex shapes has the beneficial effects that the pivot positions of the parts can be accurately changed through rotation and position adjustment of the clamping pieces in the adjustable positioning mechanism.
