Adsorption jig with built-in vacuum generator

Abstract

The invention discloses an adsorption jig with a built-in vacuum generator; the adsorption jig comprises a tooling plate, the vacuum generator, a fast connector, a shunt block, first air pipes, L-shaped connectors, hardware and suckers; the vacuum generator is connected with an external air source with stable pressure through the fast connector which is connected with the vacuum generator, and is communicated with the shunt block; at least two first air pipes are connected onto the shunt block; the port of each first air pipe is connected with the L-shaped connector; through holes are arranged in the tooling plate; one end of each through hole is provided with the L-shaped connector and is connected with the shunt block through the first air pipe, and the other end of each through hole is provided with the hardware; the suckers in the same number with the first air pipes are assembled on the hardware; the surface of the tooling plate is provided with a positioning side and at least two positioning columns; the built-in vacuum generator replaces an external vacuum pump to work; and the vacuum generator has a small size and a simple structure, and is low in cost, can be arranged in the tooling plate only by leaving a smaller space in the internal structure of the tooling plate to form a complete integral design, so that not only is the performance excellent but also the appearance is attractive and generous.

Description

technical field [0001] The invention belongs to the field of jig design, and relates to a vacuum adsorption jig, in particular to an adsorption jig that uses a built-in vacuum generator instead of an external vacuum pump. Background technique [0002] Fixtures are a large class of tools for woodworking, ironwork, fitter, machinery, electric control, and other handicrafts. They are mainly used as a tool to assist in controlling position or action (or both), in order to solve practical problems or achieve certain Auxiliary devices made specifically for each function. It has been widely used before the industrial age, including mechanical jigs, woodworking jigs, welding jigs, jewelry jigs, and jigs for other fields. Certain types of jigs are also known as "molds" or "tools" and their main purpose is to accurately repeat the reproduction of a part. With the development of industry, in order to improve production efficiency more effectively, reduce labor intensity and operation...

Problems solved by technology

Most of the fixtures on the market are clamping fixtures and holding fixtures. Clamping fixtures and holding fixtures are generally clamped on the workpiece, which is easy to clamp and deform the workpiece, especially for relatively weak workpieces. To highlight; a small amount of adsorption fixtures on the market also adsorb the suction cup on the surface of the workpiece, which will interfere with the workpiece during processing, causing a lot of inc
