[0019] To make the objectives, features, and advantages of the present utility model more obvious and understandable, the following will clearly and completely describe the technical solutions in the present utility model with reference to the accompanying drawings in the specific embodiments. Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this patent.

[0020] Now refer to the attached Figure 1 and 2 and, in combination with specific embodiments, the description is as follows: A process hole sealing cover plate for a fixed workbench of a machine tool according to the present utility model includes an upper cover plate 1 corresponding to the process hole. The upper cover plate 1 is made of a corrosion-resistant and high-strength material. A sealing ring 2 is provided at the bottom side edge of the upper cover plate 1. Specifically, a semicircular installation groove 101 is formed at the bottom side edge of the upper cover plate 1, and the sealing ring 2 is arranged inside the installation groove 101.

[0021] A lower cover plate 3 corresponding to the upper cover plate 1 is provided below the upper cover plate 1. The lower cover plate 3 is an elastic plate and is made of a corrosion-resistant and highly elastic material. A sandwich space is formed between the upper cover plate 1 and the lower cover plate 3. The lower cover plate 3 can squeeze the sealing ring 2, so that the outer part of the sealing ring 2 protrudes from the edges of the upper cover plate 1 and the lower cover plate 3.

[0022] Specifically, an installation hole is formed at the center of the upper cover plate 1, and a connecting bolt 5 is arranged in the installation hole. A connecting block 4 is provided at the center of the lower cover plate 3. A screw hole corresponding to the connecting bolt 5 is formed at the top side of the connecting block 4. The upper cover plate 1 and the lower cover plate 3 are screwed together through the connecting block 4 and the connecting bolt 5, thus forming a detachable connection structure.

[0023] The working principle of the present utility model: This sealing cover plate is used to seal the process hole on the fixed workbench 6. Taking the process hole as a circular hole as an example, the upper cover plate 1 and the lower cover plate 3 are both circular plates, and the sealing ring 2 is an O-ring. During the specific use process, the staff first loosens the connecting bolt 5. At this time, the lower cover plate 3 does not squeeze the sealing ring 2, and the sealing ring 2 is in the initial state. Then, this sealing cover plate is placed in the process hole. Finally, the connecting bolt 5 is tightened again. Under the action of the connecting bolt 5, the lower cover plate 3 will squeeze the sealing ring 2 to extrude the outer part of the sealing ring 2, so that the sealing ring 2 closely fits the inner wall of the process hole, that is, the sealing of the process hole is realized.

[0024] During the sealing process, the operator can adjust the extrusion pressure of the lower cover plate 3 by adjusting the tightness of the connecting bolts 5, thereby adjusting the volume of the extruded part of the sealing ring 2. That is to say, the tighter the connecting bolts 5 are screwed, the greater the extrusion pressure of the lower cover plate 3, and the more the sealing ring 2 is extruded, thus improving the sealing effect of this sealing cover plate and the firmness of this sealing cover plate. At the same time, the sandwich structure also significantly reduces the weight of this sealing cover plate, facilitating the operator to pick up and place it.

[0025] In one embodiment, the installation groove 101 adopts a semi-surrounding structure with open forms on both the outer side and the bottom side. Through the above semi-surrounding structure, the sealing ring 2 is more easily extruded, thereby further improving the sealing effect of this sealing cover plate.

[0026] In one embodiment, the lower cover plate 3 and the connecting block 4 are connected by bonding, riveting or welding processes. Through the above connection processes, the firmness of the lower cover plate 3 and the connecting block 4 can be ensured, thereby further improving the firmness of this sealing cover plate.

[0027] The various embodiments in this specification are described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other.
