Machine tool dovetail grinding fixture

Abstract

The invention discloses a machine tool dovetail grinding fixture, and belongs to the technical field of design of machine tool fixtures. The machine tool dovetail grinding fixture comprises a fixture body, a connecting pin, a side surface positioning plate, a pressing plate, a slotted countersunk flat head screw, a hexagonal nut, a bolt, a connecting base, a round head nut, a pressing screw rod, a positioning base, a positioning screw, a support block, a movable connecting bolt and vertical plates; the vertical plates are respectively arranged on the left and right sides of the fixture body; the movable connecting bolt penetrates through the vertical plates, and the left end is tightened by the nut; the side surface positioning plate and the movable connecting bolt are connected by the connecting pin; a workpiece is supported by the support block, and the right end is pressed by the pressing plate; the connecting base and the pressing plate are connected by the slotted countersunk flat head screw; the round head nut is fixed in the fixture body on the right side; the pressing screw rod is screwed with the round head nut to penetrate through the fixture body on the right side to connect with the connecting base; the positioning base is fixed in middle of the back side surface of the fixture body; and the positionin screw is screwed in the positioning base. The machine tool dovetail grinding fixture is simple in structure, convenient to press the workpieces and convenient to operate the pressing screw rod, and achieves multiple purposes by one fixture.

Description

technical field [0001] The invention relates to the technical field of machine tool fixture design, in particular to a machine tool dovetail grinding fixture. Background technique [0002] In the production process of the enterprise, we will often use a large number of various fixtures. The use of these fixtures will greatly improve work efficiency and benefits, and the positioning accuracy of the workpiece will also be greatly improved, reducing a lot of manpower and contributing to the development of the enterprise. It plays a very good role in promoting. The dovetail guide rail is generally located on the column or base of the machine tool, and the size of the column and the base of the machine tool is large. The traditional fixture structure is complicated, it is troublesome to press, the clamping efficiency is low, and the operation is inconvenient. The limitations are large, so it is very necessary to design a machine tool dovetail grinding fixture with simple structur...
