Double-surface milling machine tool with special three-direction fixing clamp

Abstract

The invention discloses a double-surface milling machine tool with a special three-direction fixing clamp, and belongs to the field of machining equipment. The double-surface milling machine tool withthe special three-direction fixing clamp comprises a double-surface milling machine tool body, wherein a working bench is fixedly connected to the upper end of the double-surface milling machine toolbody; the left upper end and the right upper end of the double-surface milling machine tool body are respectively and fixedly connected with a vertical column; the two vertical columns are respectively positioned at two sides of the working bench; a sliding groove is dug at one end of each vertical column; main-shaft box sliding plates are connected to the sliding grooves in a sliding manner; main-shaft boxes are connected to the outer ends of the main-shaft box sliding plates in the sliding manner; the three-direction fixing clamp is arranged at the upper end of the working bench and comprises two side-direction clamping plates which are connected with the working bench in the sliding manner. The double-surface milling machine tool disclosed by the invention has the beneficial effects that the effect of clamping the upper part and the side surfaces of a workpiece can be realized, and the control on the up-down freedom degree and the left-right freedom degree of the workpiece is realized, so that the workpiece is not easy to move due to influence of cutting force and the machining accuracy of the workpiece is improved.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, and more specifically relates to a double-sided milling machine tool with a special tripartite fixing fixture. Background technique [0002] A milling machine refers to a machine tool that mainly 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 and grooves, as well as various curved surfaces and gears. In the process of general workpiece processing, the milling machine needs to mill the four sides of the workpiece. Using a double-sided milling machine can mill both sides at the same time, which has higher processing efficiency than ordinary milling machines. [0003] However, during the use of the existing double-sided milling machine tools, since there is a spindle box on each side, and because bot...

Problems solved by technology

[0003] However, during the use of the existing double-sided milling machine tools, since there is a spindle box on each side, and because both sides of the workpiece are processed simultaneously, multiple workpieces cannot be clamped effectively, and the actual machining process will also be affected by the cutting force. And make the workpiece move, affecting the machining accuracy
