Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a five-axis machining center fixture. Background Art

[0002] The five-axis linkage machining center, also known as the five-axis machining center, is a high-tech, high-precision machining center specifically used for machining complex surfaces. This machining center system has a significant influence on a country's aviation, aerospace, military, scientific research, precision machinery, high-precision medical equipment and other industries.

[0003] The center fixture mainly uses the machine tool to position the workpiece. During use, the position of the fixture and the lifting plate is adjusted by the ball screw. When the five-axis machining arm is processing, the workpiece itself is static. When processing special-shaped parts, it will affect the difficulty of adjusting and controlling the special-shaped parts. The material head left on the process table is small, with only a dovetail tape of no more than 4.5mm, which is convenient for the subsequent removal of the process table, but its processing angle is not easy to adjust, and it cannot better cooperate with the five-axis machining center. The flexibility of the fixture during processing needs to be improved. Summary of the invention

[0004] The purpose of the utility model is to provide a five-axis machining center fixture to solve the above-mentioned defects caused by the prior art.

[0005] A five-axis machining center fixture includes a base, a lifting box is arranged directly above the base, and a turning mechanism is arranged on the outer side of the base. The turning mechanism rotates and switches the outer side of the lifting box, adjusts the processing position of the lifting box and the workpiece arranged above, and improves the flexibility of workpiece processing. A clamping mechanism is arranged directly above the lifting box, and the clamping mechanism is laterally displaced at the top of the lifting box to adjust the processing position, so as to facilitate the five-axis machining lathe to process the workpiece.

[0006] Preferably, the clamping mechanism includes guide grooves, ball screws, a lifting frame, an electric cylinder and a guide block. The guide grooves are arranged at equal intervals on the top of the lifting box. A ball screw is arranged on the outside of one group of the guide grooves. A guide block is connected through the outside of the ball screw. A lifting frame is arranged directly above the guide block. Electric cylinders are distributed in a rectangular shape on the outside of the lifting frame.

[0007] Preferably, the guide groove is connected with the guide block through a ball screw arranged inside.

[0008] The turning mechanism includes a positioning shaft, a driven gear plate, a motor, a driving gear and a rubber pad. Positioning shafts are provided on both sides of the lifting box. A shaft on one side of the lifting box is connected to a driven gear plate. One side of the driven gear plate is meshedly connected to a driving gear. One side of the driving gear is connected to an output end of the motor. The motor is installed on one side of a base. Rubber pads are symmetrically distributed on both sides of the base.

[0009] Preferably, the lifting box is connected to the inner end of the base by positioning shafts on both sides.

[0010] Preferably, the lifting box is connected to the outer side of the positioning shaft by rubber pads symmetrically distributed on both sides.

[0011] Preferably, a slag receiving pan is provided directly above the base.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. The fixture seat is displaced laterally by the screw rod. When multiple sets of fixtures arranged on the outside of the fixture seat clamp the outside of the workpiece, the fixture seat is driven to displace and switch by the screw rod, and then the processing position of the five-axis machining center is adjusted and controlled, reducing the difficulty of processing and adjusting irregular parts. The bottom end of the lifting frame is positioned through the guide groove, and the outside of the workpiece is clamped by the lifting frame to improve the efficiency of positioning workpieces at different positions.

[0014] 2. During use, the motor drives the driving gear to rotate, and the driving gear drives the driven gear plate to engage. The driven gear plate rotates and adjusts one side of the lifting box set on one side to adjust the position of the workpiece and the machine tool. During the processing of the workpiece, the workpiece is tilted so that the debris on the upper surface of the workpiece falls directly onto the surface of the slag receiving plate, thereby improving the flexibility of switching and adjusting different positions of the workpiece.
