Description

A New Type of Lateral Positioning and Clamping Device

technical field

The invention relates to the technical field of lateral positioning clamping, in particular to a novel lateral positioning clamping device.

Background technique

In the machining and manufacturing process, some general-purpose machining equipment is often used, such as: lathes, milling machines, grinding machines, and CNC machining tools. When parts processing is required, some general clamping tools and clamping methods are used to clamp the parts. Such as: flat-nose pliers, chucks, suction cups, disks, compression blocks, etc. These methods can usually meet the processing and clamping requirements of most parts. However, when the parts are processed and manufactured, the clamping method will also interfere with the processing of the parts, and at the same time affect the continuity of mechanical cutting. For example, when processing some relatively large and not too thick plate workpieces, it is not appropriate to use vise, chuck, suction cup, magnetic disk and other clamping methods. It will choose to use the pressure plate to press and fix the plate workpiece on the workbench, and then mill the parts. During the plane machining process of the milling cutter, the milling cutter must avoid the position of the pressure plate. In this case, the material under the pressure plate cannot be milled, resulting in discontinuous and incoherent processing. , use the pressure plate in another position, perform the second clamping of the part, and then process the material of the interference part of the pressure plate during the first processing. And when clamping the workpiece with the pressing plate at every turn, the combination of parts such as T-bolts, lock nuts, pressing plates, pads and the like can be used to make the pressing plate press the workpiece. There are many problems like this: (1), repeated clamping increases the workload, (2), divided processing affects the precision of plane machining, the plane machining has no continuity, and the surface is not beautiful. (3) When the part is clamped multiple times, the position of the part will change, which will affect the positioning accuracy of the clamping.
