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

[0013] Embodiment 1: with reference to attached figure 1 and 2 . A vacuum working platform composed of special air valves for deburring machines, which includes a vacuum working platform for deburring machines, a plurality of negative pressure suction holes are opened on the table surface of the vacuum working platform 8 of the deburring machine, and the negative pressure suction An air valve 7 is installed on the back of the hole, and the upper valve body 1 of the air valve 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 non-working state. 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 low...

Embodiment 2

[0014] Embodiment 2: with reference to attached figure 1 and 3 -4. On the basis of Embodiment 1, a deburring machine composed of a special vacuum working platform for deburring machines, which includes a deburring machine, the lower end of the rocker arm 9 is in rotation and plugged with the vacuum working platform 8 tables, and the biaxial motor 15 The handle assembly 4 is installed at the end of the rocker arm, and the handle assembly 4 is connected with the central axis and the hole at the end of the rocker arm. The handle assembly 4 can rotate 360 ​​degrees around the center of the end of the rocker arm, and can rotate at 45°90 ° and 180° position quick lock. Sand sheet brush head 5 and polishing brush plate 6 are respectively equipped with at the two ends of biaxial motor 15, and a plurality of negative pressure suction holes are arranged on the table top of the vacuum work platform in the described deburring machine, and the negative pressure suction holes are installe...

Embodiment 3

[0015] Embodiment 3: On the basis of Embodiments 1 and 2, a negative pressure control method of a vacuum work platform composed of a special air valve for deburring machines, when there is no workpiece at the port 1 of the upper valve body, the Negative pressure sucks the elastic valve chip 2 to the sealing table around 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 the upper valve body port is closed. Negative pressure air flow is generated; when there is a workpiece at the upper valve body port, the negative pressure air flow 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 from the lower valve body port The compressed air flow directly acts on the workpiece through the negative pressure suction ...

Abstract

The invention relates to a vacuum workbench composed of air valves special for a deburring machine, the deburring machine and a negative pressure control method. When no workpiece is arranged on an upper valve body opening, a negative pressure suction from a lower valve body opening sucks an elastic valve core on a sealed table top on the circumference of a valve opening of the interior cavity of a lower valve body, and an air flow passage between an upper valve body cavity and a lower valve body cavity is closed by an elastic valve core sheet, so that no negative pressure air flow is generated on the upper valve body opening; when one workpiece is arranged on the upper valve body opening, the negative pressure air flow from the lower valve body opening forms a vacuum state in the upper valve body cavity and the lower valve body cavity, the elastic valve core sheet is in an open state, and the negative pressure air flow from the lower valve body opening directly acts on the workpiece through a negative pressure air suction hole in the vacuum workbench and firmly sucks the workpiece. The invention has the following advantages that: 1.the vacuum workbench is simple in structure, free to control, reliable in self-control and good in effect; 2. the vacuum suction on the workpiece is greatly improved, and smaller workpieces are easy to process; and 3. the energy source consumption is effectively reduced and the processing cost is decreased.

Description

technical field [0001] The present invention relates to a kind of deburring machine dedicated to deburring machine under the action of negative pressure air flow, when the negative pressure suction hole on the vacuum working platform of the deburring machine is covered by a workpiece, the air valve is opened, and when there is no workpiece cover, the air valve is closed. A vacuum working platform composed of air valves, a deburring machine and a negative pressure control method belong to the field of deburring machine manufacturing. Background technique [0002] All of the applicant’s prior patent application No. 200910097298.1, titled “Dedicated Negative Pressure Conveying Table and Conveying Method for Sanding Machines”, the distance between multiple idlers is distributed on the conveying platform and driven by a sprocket transmission mechanism composed of sprockets and chains. Multiple rollers rotate synchronously, the negative pressure suction nozzle in the negative pres...
