Description

A new type of mechanical fixture

【Technical field】

The utility model relates to a mechanical clamp, in particular to a novel mechanical clamp.

【Background technique】

Fixture: A device used to fix the processing object in the process of mechanical manufacturing so that it occupies the correct position to accept construction or inspection. In a broad sense, any process in the process, the device used to install the workpiece quickly, conveniently and safely, can be called a fixture. Such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. Among them, machine tool fixtures are the most common, often referred to as fixtures. When processing a workpiece on a machine tool, in order to make the surface of the workpiece meet the technical requirements such as the size, geometric shape, and mutual position accuracy with other surfaces specified in the drawing, the workpiece must be installed (positioned) and clamped (clamped) before processing. . The fixture usually consists of a positioning element (to determine the correct position of the workpiece in the fixture), a clamping device, a tool setting guide element (to determine the relative position of the tool and the workpiece or to guide the direction of the tool), and an indexing device (to enable the workpiece to be positioned in one installation. Complete the processing of several stations, there are two types of rotary indexing device and linear moving indexing device, connecting elements and clamp body (fixture base), etc. The types of fixtures can be divided into: ①Universal universal fixtures. Such as machine The use of vise, chuck, suction cup, dividing head and rotary table, etc., has great versatility and can better adapt to the transformation of processing procedures and processing objects. Its structure has been finalized, and its size and specifications have been serialized. Most of them have become a standard accessory of machine tools. ②Special fixtures. It is specially designed and manufactured for the clamping needs of certain product parts in a certain process. The service object is specific and highly targeted. Generally, it is manufactured by the product It is designed by the factory itself. Commonly used are lathe fixture, milling machine fixture, drilling jig (machine tool fixture for guiding the tool to drill or ream on the workpiece), boring mold (machine tool fixture for guiding the boring bar to bore on the workpiece) and Accompanying fixture (for mobile fixtures on the automatic line of combined machine tools). ③ Adjustable fixture. A special fixture that can replace or adjust components. ④ Combined fixture. A fixture composed of standardized components of different shapes, specifications and uses, suitable for new Single-piece, small-batch production and temporary tasks for product trial production and frequent product changes.

The existing fixtures have certain disadvantages in the process of use. They are not suitable for disassembly and assembly during maintenance, which brings troubles in assembly to after-sales service personnel and reduces work efficiency; secondly, in the process of using fixtures, due to unstable It will lead to unbalanced force on the clamp, causing the clamped object to fall, resulting in many accidents and unnecessary loss of life and property. To this end, we propose a novel mechanical gripper.
