A vacuum clamping system

Abstract

The invention discloses a vacuum clamping system. The vacuum clamping system comprises a jig bottom plate, folding lever type vacuum pull blocks, vacuum chucks, vacuum pipes and locating basis flanges, one folding lever type vacuum pull block and a corresponding locating basis flange are arranged in each of the X direction and the Y direction of the jig bottom plate, two vacuum chucks are arranged in the Z direction of the jig bottom plate, the folding lever type vacuum pull blocks are all connected to a vacuum source through pipelines, the pipelines of the folding lever type vacuum pull blocks are all connected to the control gas path port of a vacuum sequence valve simultaneously, the two vacuum chucks are connected to the vacuum sequence valve and then to the vacuum source through pipelines, and each folding lever type vacuum pull block comprises a pull rod embedded metal block, a folding suction-pull block and a base embedded metal block. According to the vacuum clamping system provided by the invention, positioning, clamping and signal interaction can be achieved through only one power source, one control signal and one completion judging signal, the reliability in motion and control can be ensured, integration and miniaturization are easy, and the vacuum clamping system is more outstanding in applicability to small-sized products.

Description

technical field [0001] The invention relates to the field of tooling accessories, in particular to a vacuum clamping system. Background technique [0002] As we all know, in product positioning and clamping, positioning requires external force to hold the product against the reference edge or hole, and clamping requires a force that can resist external force to fix the product, so as to ensure that the product can be assembled, processed and transmitted There is a definite position in the operation, and these two actions must be positioned first, and then clamped, so as to ensure the accuracy of positioning and the reliability of clamping. At present, the force required for these positioning and clamping generally comes from cylinders, motors, vacuum or springs, and generally must be combined to meet the needs of positioning and clamping, so its shortcomings are also reflected. One is its power. Components, such as cylinders, motors, springs, etc., require a large installat...

Problems solved by technology

At present, the force required for these positioning and clamping generally comes from cylinders, motors, vacuum or springs, and generally must be combined to meet the needs of positioning and clamping, so its shortcomings are also reflected. One is its power. Components, such as cylinders, motors, springs, etc., require a large installation space, and some such as springs also need external forces to retreat, which is almost impossible to design for some small and compact occasions, especially for small products. Control successively, that is, use an output switch to control the positioning of the product, and then detect the product positioning completion signal or a certain delay, then output the clamping control signal, and then perform the clamping completion state judgment signal. A lot of input and output ports are required for judgment and control, which is not conducive to simplification
