[0006] The utility model is implemented by the following technical scheme: a grinding machine cylinder, comprising a cylinder body, annular blocks are arranged on the top and bottom of the cylinder body, a clamping groove is opened on the outer side of the annular block, a fixing component is fixedly connected with the surface of the bottom annular block at equal intervals, the cylinder body and the two annular blocks are an integral structure, a connecting groove is opened on one side of the inner wall of the annular block, a connecting hole is opened between the two connecting grooves, and exhaust ports are opened at equal intervals on the surface of the cylinder body.

[0007] As a further improvement of the above scheme, the fixing assembly includes a limiting cylinder, a bevel gear A is installed inside the limiting cylinder, two bevel gears B are meshingly connected to the surface of the bevel gear A, a screw rod is connected through the axis of the bevel gear B, and a threaded cylinder is threadedly connected to the outer side of the screw rod, so as to facilitate fixing the cylinder body.

[0008] As a further improvement of the above solution, a bearing is installed on the outer side of the screw rod, and one end of the bearing is fixedly connected to the inner wall of the limiting cylinder to ensure the normal operation of the screw rod.

[0009] As a further improvement of the above scheme, a limiting ring is sleeved on the outer side of the threaded barrel, a guide rod is provided through the surface of the limiting ring, one end of the guide rod is fixedly connected to the inner wall of the limiting barrel to ensure that the threaded barrel does not deflect during movement.

[0010] As a further improvement of the above solution, a through hole for the limiting cylinder to pass through is provided on the surface of the limiting cylinder to ensure that the threaded cylinder can move outward normally.

[0011] As a further improvement of the above solution, a rotating shaft is fixedly connected to the top of the helical gear A. The rotating shaft is rotatably connected to the top of the limiting cylinder, and a handwheel is fixedly connected to the top of the rotating shaft to facilitate the rotation of the helical gear A.

[0012] As a further improvement of the above solution, grooves are equidistantly arranged on the top of the annular block to facilitate the movement of the cylinder body of the moving cylinder.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By setting the fixing component in the present utility model, when installing, place the cylinder body at the installation position, and then rotate the helical gear A, so that the helical gear A drives the two helical gears B to rotate. The rotation of the helical gear B causes the lead screw to rotate. Under the action of the guide rod and the limiting ring, the threaded cylinder moves outward, so that the threaded cylinder is inserted and connected to the outside, thereby fixing the cylinder body, making the connection between the cylinder body and the outer cover closer, the device works more stably, and the airtightness of the device is better.

[0015] 2. By setting two annular blocks in the present utility model, place the cylinder body on the bottom of the outer cover, and fix and install the cylinder body through the fixing component. The clamping grooves provided on the annular blocks make the connection between the cylinder body and the outer cover closer, and the limiting posts on the outer cover just insert into the internal communication holes for limiting connection, improving the sealing degree between the cylinder body and the outer cover. At the same time, since the exhaust ports are equidistantly arranged on the surface of the cylinder body, the uniform exhaust method can reduce the pressure fluctuation inside the cylinder, thereby reducing the stress on the internal structure of the cylinder, which helps to improve the service life and reliability of the cylinder.
