Abstract

The invention relates to a positioning and clamping device for milling small-size flat long and thin parts. The positioning and clamping device is characterized in that: a groove is formed on the lateral surface of a clamp body (1); at least two positioning holes are formed on the side of the groove; a limit pin (3) is arranged on each positioning holes; a guiding element (8) is connected below the clamp body (1), and a guiding groove is formed on the middle part of the guiding element; a clamping element (4) is connected to a holder (9); the holder (9) is connected with a cylinder (7) and ispositioned in front of the groove of the clamp body (1); the clamping element (4) is provided with clamping arms in a direction which is opposite to the clamp body (1); the clamping arms of left and right sides are positioned in the guiding groove of the guiding element (8); the cylinder (7) is positioned below the guiding element (8) and is connected with the holder (9) through an expansion linkin front of the guiding element; and the positioning and clamping device is arranged on an operating platform of a numerically controlled milling machine. The positioning and clamping device can improve the integral machining accuracy, machining quality and the production efficiency of machining the parts.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, in particular to a positioning and clamping device and method for processing small flat and slender parts. Background technique [0002] The extensive use of machining centers has greatly changed the production mode of the machinery manufacturing industry. Small machining centers have a greater advantage in price and are more widely used. Most of these machining centers are vertical structures. If small flat and slender parts are to be processed (such as figure 1 ) on the planar structure, the position of the part during processing must be perpendicular to the workbench. [0003] Usually, the processing of such parts can use multiple copy mills and special feeding and clamping mechanisms. Its disadvantage is that multiple clamping is required, it is difficult to adjust after changing the tool, and it is difficult to ensure the consistency of the processing size. The machining ce...
