[0016] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0018] like Figure 1 to Figure 4 As shown, a straight-mouth quick clamping and positioning tool comprises: a tool body 1, a plurality of positioning blocks 2; the bottom surface of a workpiece 3 to be processed is placed above the upper plate surface of the tool body 1, the positioning blocks 2 are evenly distributed on the upper plate surface of the tool body 1 along the circumferential direction, the outer contour of the positioning blocks 2 is adapted to the inner contour of the workpiece 3 to be processed, and the outer side wall of the positioning blocks 2 abuts against the inner wall of the workpiece 3 to be processed. Only the outer contour of the positioning blocks 2 needs to be processed to form a positioning straight mouth required by different processing process margins with the tool body 1.

[0019] It also includes: a shaft disc 4, a plurality of screw rods 5, and a plurality of clamping nuts 6; the plurality of screw rods 5 are evenly distributed along the circumference of the tooling body 1, and the screw rods 5 are all arranged on the outside of the workpiece 3 to be processed. The tooling body 1 is provided with a plurality of threaded rod mounting holes 10 corresponding to the positions of the threaded rods 5, one end of the screw rod 5 is inserted into the threaded rod mounting hole 10, and the other end of the screw rod 5 is provided with threads, and the plurality of screw rods 5 pass through the shaft disc 4 and are screwed to the clamping nuts 6, and the clamping nuts 6 press the shaft disc 4 against the top surface of the workpiece 3 to be processed. The shaft disc 4 and the plurality of screw rods 5 realize the positioning of the workpiece 3 to be processed, so that the workpiece 3 to be processed cannot move up and down.

[0020] It also includes: a plurality of locking screws 7, two positioning block mounting holes 20 are symmetrically provided on the positioning block 2, a plurality of corresponding positioning block threaded holes 11 are opened on the upper plate surface of the tooling body 1, and the locking screws 7 pass through the positioning block mounting holes 20 and the positioning block threaded holes 11 in sequence to fix the positioning block 2 on the upper plate surface of the tooling body 1. Fixing the positioning block 2 with the locking screws 7 facilitates loading and unloading and processing.

[0021] A central through hole 12 is formed at the center of the tool body 1 .

[0022] The tool body 1 is made of aluminum alloy.

[0023] In summary, when rough machining, semi-finishing and finishing are performed on the workpiece, the straight mouth allowance required by the positioning tool is different. Before the start of processing, the outer contour of the positioning block 2 is processed according to the workpiece allowance to ensure that it matches the inner contour of the workpiece, and four positioning block 2 blanks are installed on the upper surface of the tool body 1 with locking screws 7. Place the workpiece 3 to be processed into the tool body 1, and then pass the shaft disc 4 through the screw rod 5, screw it with the clamping nut 6 and the screw rod 5, and then press the workpiece 3 to be processed for processing. After the rough machining of the workpiece 3 to be processed is completed, repeat the above operation and then perform fine machining. Realize rapid positioning of the straight mouth and the workpiece, ensure that the position and gap of each clamping are the same, prevent the workpiece from being unstable during clamping or machining deformation, and improve the stability of workpiece quality.

[0024] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
