Description

A milling machine fixture

technical field

The utility model discloses a milling machine fixture, which belongs to the mechanical field.

Background technique

The fixture device is mainly used for milling parts with planes with different angles and plate parts with inclined grooves.

In modern machining, when milling a plane with an angle, the required angle is usually measured with a ruler, and then fixed by using pads, bolts, and pressure plates. The clamping process is time-consuming and laborious, and the angle is difficult to guarantee. When the angle changes, it needs to be repeated. Carrying out above operation, production efficiency is difficult to improve.

Contents of the invention

The purpose of this utility model is to overcome the problems of the above-mentioned prior art and provide a milling machine clamp with simple structure and convenient operation.

The technical scheme of the utility model is that the side wall (2) of the base is fixedly connected with the shaft sleeve (3) by bolts, and the shaft sleeve and the shaft (4) cooperate to form a hinge mechanism. The other end is fixedly connected with the shaft (6) by bolts, the shaft (6) cooperates with the nut (7) with the shaft hole, and the nut (7), lead screw (8), bevel gear (9) and guide rail (10) are composed Nut screw mechanism, the guide rail (10) is connected to the base through the spacer (11), the rocker arm (12) is installed on the bevel gear shaft, and the bevel gear (9) is driven to rotate by rotating the rocker arm, and the bevel gear drives the thread through meshing transmission. The rod (8) rotates, the threaded rod pushes the nut (7) to move up and down, drives the working plate to change the angle, and the working plate drives the shaft (4) to rotate, forming a relative rotation angle with the bushing (3), and the side wall (2) is equipped with a dial (13), pointer (14) is housed on the axle (4), reads the angle of working plate plane and horizontal plane by dial. Between the guide rail (10) and the base (1), the adjustment range of the angle of the working plate can be expanded by increasing or decreasing the number of pads.

The utility model has a simple structure and can effectively improve the processing efficiency.

Detailed ways

The fixture device, as shown in Figure 2, includes a fixture base 1, a side wall 2, and a shaft sleeve 3 is installed on the side wall 2 through bolts. The shaft 4 cooperates with the shaft sleeve 3 to form a hinge mechanism, and the working plate 5 is connected to the shaft 4 through bolts. , the parts are fixed on the working plate through bolts and pressure plates, the other end of the working plate is connected with the shaft 6, the shaft 6 cooperates with the nut 7 with the shaft hole, the nut 7, the screw 8, the bevel gear 9, and the guide rail 10 form the nut screw Mechanism, the rocker arm 12 is connected with the bevel gear, by rotating the rocker arm, gear meshing, and thread transmission, the nut is pushed to move up and down, and the angle of the working plate is adjusted.

When processing workpieces, first rotate the rocker arm, and then tighten the clamping bolts 15, 16 after reading the required angle from the dial. If the angle of the part plane exceeds the adjustment range of the workbench, increase or decrease the number of pads to increase the adjustment range of the workbench.

After the parts are clamped, use a feeler gauge to check the tool, and tighten the bolts to fix the clamp on the milling machine table for processing.
