Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
As shown in fig. 1-2, in the embodiment of the present application, the present invention provides a vacuum chuck, comprising:
the base 1 is used for mounting the top cover 2; an air exhaust hole 3 is formed in the base 1;
the top cover 2 is used for mounting a negative pressure screw 4; the top cover 2 is provided with a mounting hole 5; a sealed installation cavity is formed between the base 1 and the top cover 2, and the air suction hole 3 and the installation hole 5 are both connected with the installation cavity;
the negative pressure screw 4 is used for forming negative pressure at the mounting hole 5; the negative pressure screw 4 comprises a rod body 6, the tail end of the rod body 6 is provided with a negative pressure port 7, the side wall of the rod body is provided with an air outlet 8, and the negative pressure port 7 is connected with the air outlet 8; the negative pressure screw 4 is movably arranged in the mounting hole 5;
when the rod body 6 moves to a preset position in the mounting hole 5, the air outlet 8 is connected with the mounting cavity.
In this application embodiment, when using this vacuum chuck, be connected aspirating hole 3 with external air exhaust device, then rotatory negative pressure screw 4 makes it support tight base 1, and at this moment, gas outlet 8 is connected with the installation cavity, and the face that is provided with mounting hole 5 on the top cap 2 is close to the object that waits to inhale tightly, opens air exhaust device simultaneously and bleeds, and mounting hole 5 department forms the negative pressure and inhales tightly the object. The number of the negative pressure screws 4 to be rotated can be selected according to the area of the object. Two aspirating holes 3 are symmetrically arranged on the base 1, the two aspirating holes 3 are simultaneously connected with an external air extractor to generate larger negative pressure, and the adsorption force generated at the mounting hole 5 is stronger.
In the embodiment of the present application, as shown in fig. 1-2, support pillars 9 are arranged in an array on the surface of the base 1 facing the top cover 2, and the support pillars 9 abut against the top cover 2.
In the embodiment of the present application, the base 1 and the top cover 2 are connected to each other by screws or adhesive, a sealed installation cavity is formed between the two, and the supporting column 9 is used for supporting the top cover 2.
As shown in fig. 1-2, in the embodiment of the present application, a mounting position 10 is formed between two adjacent supporting pillars 9, and the negative pressure screw 4 includes a cap 11 connected to the rod 6, and when the rod 6 moves to a predetermined position in the mounting hole 5, the cap 11 is disposed in the mounting position 10.
In the embodiment of the application, when the negative pressure screw 4 is not rotated, the cap body 11 of the negative pressure screw 4 is abutted against the top cover 2, at this time, the rod body 6 is completely positioned in the mounting hole 5, and the air outlet 8 is sealed by the inner wall of the mounting hole 5 and cannot be connected with the mounting cavity; when the negative pressure screw 4 is rotated to be abutted against the base 1, the cap body 11 of the negative pressure screw 4 is far away from the top cover 2 and extends into the mounting position 10, and at the moment, the air outlet 8 on the rod body 6 is connected with the mounting cavity.
