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 sanding and 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 the In the non-working state, it is in the normally open state; the diameter of the valve cavity of the upper valve body 1 is larger 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 When the 2 surfaces are joined with the sealing surfaces 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 a...

Embodiment 2

[0010] Embodiment 2: On the basis of Embodiment 1, an automatic control method for the special air valve of the negative pressure conveying platform of a sanding and 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 will The elastic valve chip 2 is attracted to the sealing surface around the valve port in the inner cavity of the lower valve body 3. At this time, the air flow channel 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 an open state, and the negative pressure airflow from the lower valve body port acts...

Abstract

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 Special air valve and control method, the upper valve body and the junction with the lower valve body are provided with an elastic valve chip for closing the passage of the upper valve body cavity and the lower valve body cavity, and the elastic valve chip is in a normally open state in a non-working state. Advantages: First, it solves the problem of automatic distribution of vacuum suction that those skilled in the art have been unable to achieve for a long time. It uses its own negative pressure airflow to realize the automatic opening or closing of the negative pressure suction hole in the negative pressure conveying platform of the deburring machine. It has the advantages of simple structure, free self-control, reliable self-control, and good effect; second, it greatly improves the vacuum suction force on the workpiece, which makes the range of workpieces that can be processed larger, and the processing of smaller workpieces becomes easier; third, it effectively reduces Reduce energy consumption and reduce processing costs.

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] The applicant’s prior patent application number 200910097298.1, titled “Special Negative Pressure Conveying Platform and Conveying Method”, the distance between multiple idler rollers is distributed on the conveying platform, and the sprocket transmission mechanism composed of sprockets and chains drives multiple idlers. The rollers rotate synchronously, and the negative pressure suction nozzle in the negative pressure box is connected with the negative pressure suction nozzle of the negat...
