[0013] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0014] Specific embodiment 1: Please refer to Figures 1 to 4 In an embodiment of the utility model, a positioning tool comprises a base plate 1, and at least two placement grooves 101 matching the shape of the product 8 are provided on the base plate 1. In this embodiment, two placement grooves 101 are provided on the base plate 1, and the two placement grooves 101 are centrally symmetrically arranged. The arrangement of the two placement grooves 101 can enable another set of tooling to clamp the product while the machine tool is processing a set of products, so that auxiliary operations and processing time are carried out simultaneously, reducing mold change time. A plurality of adjustable clamping mechanisms 2 with the same structure are provided along the periphery of the placement groove 101. In this embodiment, three adjustable clamping mechanisms 2 are provided outside each placement groove 101 to perform pressing and positioning on the product in the placement groove 101. The adjustable clamping mechanism 2 is fixedly connected to the base plate 1. A plurality of long-structured mounting holes 102 are respectively provided on the left and right sides of the base plate 1. In this embodiment, two mounting holes 102 are respectively provided on the left and right ends of the base plate 1, which facilitates the installation of the base plate 1 and the machine.

[0015] The adjustable clamping mechanism 2 includes a support rod 3, an adjustment rod 4, a clamping rod 5 and a clamping block 6. The support rod 3 is vertically fixed on the base plate 1. The adjustment rod 4 is vertically installed above the support rod 3. A first fixing ring 402 is provided above the support rod 3. A side above the adjustment rod 4 is provided with an adjustment groove 401 with an inwardly concave long structure. The side of the adjustment rod 4 with the adjustment groove 401 passes through the first fixing ring 402. The first fixing ring 402 is provided with a fixing hole 402-1. The fixing hole 402-1 and the adjustment groove 401 are connected to each other. The fixing hole 402-1 is connected with a fixing screw in thread connection and contacts the bottom end surface of the adjustment groove 401. The clamping rod 5 includes a threaded portion 501 and a handle 502. The handle 502 is above the threaded portion 501. A second fixing ring 403 is provided on the other side of the support rod 3. The clamping rod 5 passes through the second fixing ring 403 and is threadedly connected with the second fixing ring 403. The pressing block 6 is fixed below the clamping rod 5. The pressing block 6 is a circular structure. The pressing block 6 is made of plastic material, which can effectively prevent the pressing block 6 from crushing the product. Since the adjustment groove 401 is a long structure, that is, the operator can adjust the position of the clamping rod 5 according to the required clamping position. It only needs to adjust the installation position of the adjustment rod 4 on the support rod 3. The adjustment method is simple and quick.

[0016] Compared with the prior art, the positioning tooling of the present application reduces the time for product alignment, effectively improves processing efficiency, and prevents the phenomenon of product jumping during processing. It can effectively reduce vibration during the processing, increase the service life of cutting tools and machine tools, and improve the processing quality of products.
