Abstract

A combined fixture for machining large bars by CNC, comprising fixture A, fixture B and fixture C, fixture B is a three-jaw chuck, fixture A is provided with a fixture main board above the fixture bottom plate, and the fixture main board is provided on the left and right sides of the fixture bottom plate There is one, a fixing unit is arranged above the main board of the fixture, and the fixing unit is specifically a pressure block and an M16 fixing screw above the main board of the fixture; the fixture C is provided with a bottom plate of the fixture, and the bottom plate of the fixture is connected to the main board of the fixture to form an included angle of 90°. There are two fixing units on the main board of the fixture, and the fixing unit specifically includes a pressing block and an M16 fixing screw. The present invention uses three fixtures to form a combined fixture, and divides the processing process into multiple parts, and adopts a step-by-step processing accuracy method to give The processing leaves a margin, controls the deformation of the workpiece, and avoids the poor hole size of the part and the wrong hole position processing caused by the clamping method.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a combined fixture and a clamping method for machining large bars by CNC. Background technique [0002] The earlier fixture type is mainly composed of two movable jaws and fixed jaws, and the type is relatively simple. The defects of this type are: it is easy to cause the deformation of the workpiece hole during processing, it is not easy to locate, which affects the processing accuracy, and the shape positioning is easy to cause poor hole position and processing error of the hole position. Time is also easy to cause defective parts. Contents of the invention [0003] The invention aims to provide a combined fixture and a clamping method for CNC machining large bar materials that ensure the verticality, coaxiality and cylindricity of products. [0004] In order to achieve the above-mentioned technical purpose, the present invention adopts the following technical soluti...
