Workpiece clamp for milling machine

Abstract

The invention discloses a workpiece clamp for a milling machine. The workpiece clamp comprises a working bench, sliding rails, oblique wedges, fixing rods, a support column, and an oil cylinder. The workpiece clamp is characterized in that the multiple sliding rails are arranged and the sliding rails are installed at the upper portion of the working bench radially; the oblique wedges are connected with the sliding rails in a movable manner; the fixing rods are fixedly connected with the oblique wedges, and the distances between each fixing rod and the working bench center are the same; the support column is in a cylindrical shape, oblique wedge openings are formed in the outside of the upper end of the support column, and the angles of the oblique wedge openings are matched with the angles of the lower surfaces of the corresponding oblique wedges; and the oil cylinder is installed at the bottom of the working bench and located in the axis of the working bench, a telescopic rod of the oil cylinder is connected with a central point on the lower end face of the support column. The workpiece clamp has the advantages of being simple in structure, reasonable in design, good in using effect, strong in applicability, easy to popularize and use and the like.

Description

technical field [0001] The invention relates to the technical field of milling machine equipment, in particular to a workpiece fixture for a milling machine. Background technique [0002] A milling machine mainly refers to a machine tool that uses a milling cutter to process various surfaces on a workpiece. Usually the rotation of the milling cutter is the main movement, and the movement of the workpiece (and) the milling cutter is the feed movement. It can process planes, grooves, various curved surfaces, gears, etc. A milling machine is a machine tool that uses a milling cutter to mill a workpiece. In addition to milling planes, grooves, gear teeth, threads and spline shafts, milling machines can also process more complex profiles, with higher efficiency than planers, and are widely used in machinery manufacturing and repair departments.

Problems solved by technology

[0003] When using a milling machine to process a cylindrical workpiece, the existing milling machine often uses a triangular chuck to fix the cylindrical workpiece. There are two main problems in this connection method. One is that the length of the triangular chuck extending into the workpiece is limited. , the fixed stability is limited, which is not conducive to the long-term processing of the workpiece; the second is that the flare of the triangular chuck is within a certain range, and it cannot fix the workpiece that is too large or too small
