Problems solved by technology

The disadvantage is that the multiple air holes on the surface of the negative pressure box are completely open regardless of whether there are workpieces on it, resulting in the unlimited loss of the air flow that generates negative pressure, which reduces the negative pressure and suction of the position that really needs negative pressure airflow adsorption. Small, so that the workpiece cannot be fixed during grinding, which affects the grinding effect

Embodiment 1

[0009] Embodiment 1: with reference to attached figure 1 . A special air valve for the negative pressure conveying platform of a deburring machine. The upper valve body 1 and the junction with the lower valve body 3 are provided with an elastic valve chip 2 for closing the passage of the upper valve body cavity and the lower valve body cavity, and the elastic valve chip 2 is in non-working mode. It is in the normally open state; the diameter of the valve cavity of the upper valve body 1 is smaller than the diameter of the valve cavity of the lower valve body 3, and a sealing surface for the closing of the elastic valve chip 2 is formed around the valve port of the lower valve body 3. When the elastic valve chip 2 faces When it is engaged with the sealing surface around the valve port of the lower valve body 3, the channel of the valve cavity of the upper valve body 1 and the channel of the valve cavity of the lower valve body 3 are closed, and the air flow is not conducted, ot...

Embodiment 2

[0010] Embodiment 2: On the basis of Embodiment 1, a special air valve automatic control method for the negative pressure conveying platform of the deburring machine, when there is no workpiece at the port 1 of the upper valve body, the negative pressure suction from the port of the lower valve body pushes the elastic valve The chip 2 is attracted to the sealing table around the valve port of the inner cavity of the lower valve body 3. At this time, the air flow passage between the upper valve body cavity and the lower valve body cavity is closed by the elastic valve chip 2, and no negative pressure air flow is generated at the upper valve body port; When there is a workpiece at the upper valve body port, the negative pressure airflow from the lower valve body port makes the upper valve body cavity and the lower valve body cavity form a vacuum state, the elastic valve chip 2 is in the open state, and the negative pressure airflow from the lower valve body port directly acts on t...

Abstract

The invention relates to a special air valve for a negative pressure convey platform of a deburring machine and a control method thereof; under the action of negative pressure gas flow, when a negative pressure air intake opening on the negative pressure convey platform of the deburring machine is covered with a workpiece, the air valve is opened; otherwise, the air valve is closed; the joint part of an upper valve body and a lower valve body is provided with an elastic valve plug sheet which is used for closing a channel between an upper valve body cavity and a lower valve body cavity and is in a normally open state when not works. The special air valve has the following advantages: firstly, the problem that vacuum suction can not be automatically distributed, which is not solved by technical personnel for a long time, is solved, automatic open or close of a negative pressure air intake opening in the negative pressure convey platform of the deburring machine is realized by utilizing self-owned negative pressure gas flow, the special air valve has the advantages of simple structure, flexible and reliable self control and good effect; secondly, the vacuum suction acting on the workpiece is greatly improved, thereby enlarging the range of workpieces to be processed, and processing smaller workpieces more easily; thirdly, energy consume is effectively reduced, and processing cost is reduced.

Description

technical field [0001] The invention relates to a deburring machine negative pressure conveying platform under the action of negative pressure airflow, when the negative pressure suction hole on the negative pressure conveying platform of the deburring machine is covered by a workpiece, the air valve is opened, and when the workpiece is not covered, the air valve is closed A special air valve and a control method belong to the field of air valve manufacturing. Background technique [0002] All of the applicant’s prior patent application number 200910097298.1, titled “Special Negative Pressure Conveying Platform and Conveying Method”, the distance between multiple supporting rollers is distributed on the conveying platform, and the sprocket transmission mechanism composed of sprockets and chains drives multiple supporting rollers The rollers rotate synchronously, and the negative pressure suction nozzle in the negative pressure box is connected with the negative pressure suct...
