As shown in fig. 1-4, a convenient and stable barrel clamp comprises a main shaft 1, a plurality of sleeves 2, a plurality of annular springs 3, a pull rod 4 and a disc spring 5.

The front part of the main shaft 1 is suspended, and the rear part is arranged on a bearing seat 6 and is driven to rotate by a rotary driving device, and the rotary driving device comprises general equipment such as a motor. All sleeves 2 are sleeved on the outer wall of the front portion of the main shaft 1 end to end in sequence, the last sleeve 2 is close to the bearing seat 6 and is blocked by the bearing seat 6, so that the last sleeve 2 cannot slide towards the rear portion of the main shaft 1, the first sleeve 2 is elastically connected with the main shaft 1 through the pull rod 4 and the spring, the first sleeve 2 has elastic force pressing towards the last sleeve 2, the last sleeve 2 cannot slide towards the front portion of the main shaft 1, and namely the last sleeve 2 is constant in position in the axial direction of the main shaft 1.

The core part of the main shaft 1 is provided with a through hole, the pull rod 4 is inserted into the through hole of the core part of the main shaft 1 in a sliding mode, the through hole comprises a fine hole 11 located in the front of the main shaft 1 and a coarse hole 12 located in the rear of the main shaft 1, the fine hole 11 and the coarse hole 12 are communicated coaxially, and a second step surface 13 is formed at the connecting position of the fine hole 11 and the coarse hole 12.

The pull rod 4 comprises a thin rod 41 positioned at the front part of the pull rod 4 and a thick rod 42 positioned at the rear part of the pull rod 4, the thin rod 41 and the thick rod 42 are coaxially and fixedly connected together, and a first step surface 43 is formed at the connecting part of the thin rod 41 and the thick rod 42. The thin rod 41 penetrates through the fine hole 11 in a sliding mode and is fixedly connected with the first sleeve 2, so that the first step surface 43 and the second step surface 13 are opposite, a spring is arranged between the first step surface 43 and the second step surface 13, the first sleeve 2 is elastically connected with the main shaft 1 through the pull rod 4 and the spring, the first step surface 43 and the second step surface 13 have the tendency of moving away from each other, the pull rod 4 has the tendency of moving from the front portion of the main shaft 1 to the rear portion, the linkage first sleeve 2 has the tendency of moving from the front portion of the main shaft 1 to the rear portion, and the first sleeve 2 has the tendency of pressing towards the last sleeve 2. The spring includes various springs commonly available in the market, and the disc spring is preferably selected in the embodiment. The disc spring 5 is disposed between the first and

second step surfaces

43, 13.

Each sleeve 2 has an outward inclined surface 21 at each end, the inclined surfaces 21 of adjacent sleeves 2 are opposite and have a gap, and all the annular springs 3 are sleeved between the two opposite inclined surfaces 21.

When the pull rod 4 and the first sleeve 2 are fixedly connected, the disc spring 5 enables the pull rod 4 to have elastic force moving towards the rear part of the main shaft 1, so that the first sleeve 2 has elastic force pressing towards the last sleeve 2, and all the sleeves 2 between the first sleeve 2 and the last sleeve 2 are further pressed.

At the process that first sleeve 2 compresses tightly all sleeves 2, the clearance between the adjacent sleeve 2 diminishes gradually, make sleeve 2 of ring spring 3 both sides can follow 1 axial of main shaft and move in opposite directions and extrude ring spring 3, when sleeve 2 extrudees ring spring 3, the axial force that ring spring 3 received can be transformed into radial force to inclined plane 21 on the sleeve 2, make ring spring 3 along 1 radial outside motion of main shaft, until there is not the clearance between all sleeves 2, it is whole compressed tightly, ring spring 3 is propped open to the maximum diameter by inclined plane 21 this moment, and the even tight suit of top is in the inner wall of 1 outside barrel 8 of main shaft, realize the installation of barrel 8.

The sleeve 2 also has wear-reducing grooves 22 on its inner wall for reducing the contact area of sliding friction.

The thick rod 42 at the rear part of the pull rod 4 extends out of the thick hole 12 at the rear part of the main shaft 1, and the rear side of the pull rod 4 is also provided with a telescopic driving device which is used for jacking the rear end of the pull rod 4 so as to enable the pull rod 4 to move from the rear end to the front end along the through hole of the core part of the main shaft 1.

When the pull rod 4 moves from the rear end to the front end of the main shaft 1, the first sleeve 2 moves away from the last sleeve 2, so that the sleeves between the first sleeve 2 and the last sleeve 2 are not clamped mutually any more, but have a movement gap.

Referring to fig. 1-4, the working process of the embodiment of the present invention is:

when the barrel is clamped, the cylinder 7 is driven to enable the piston rod of the cylinder to move forwards, and when the piston rod of the cylinder 7 moves forwards, the pull rod 4 is pushed to move from the rear end to the front end of the main shaft 1; the pull rod 4 can compress the disc spring 5 when moving towards the front end, and the first sleeve 2 linked and fixedly connected to the front end of the pull rod 4 moves towards the front end from the rear end of the main shaft 1 at the same time, and the annular spring 3 can gradually recover to be deformed and has a reduced diameter in the process, so that other sleeves 2 can gradually separate under the action of the annular spring 3 to generate a gap for accommodating the annular spring 3 until the annular spring 3 completely recovers to be deformed. After the annular spring 3 completely recovers deformation, the cylinder 8 to be clamped is sleeved on the outer wall of the sleeve 2, then the cylinder 7 is driven to move the piston rod of the cylinder backwards, and at the moment, the pull rod 4 can be separated from the restraint of the piston rod of the cylinder 7 and moves towards the rear end of the main shaft 1 under the effect of the disk spring 5 recovering deformation. During the backward movement of the pull rod 4, the pull rod 4 is linked with the first sleeve 2 to slide backward on the main shaft 1. In the gliding in-process backward of foremost sleeve 2, the clearance between other sleeve 2 can diminish gradually under the looks clamp effect of foremost sleeve 2 and last sleeve 2, the sleeve 2 that is located 3 both sides of ring spring can be along 1 axial extrusion ring spring 3 of main shaft, when sleeve 2 extrudees ring spring 3, the axial force that ring spring 3 received can be turned into radial force to inclined plane 21 on the sleeve 2, make ring spring 3 along 1 radial outward motion of main shaft, until the contact and the tight barrel 8 inner wall of top, thereby fix barrel 8.

Of course, the above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention, and all modifications made according to the spirit of the main technical solution of the present invention should be covered within the protection scope of the present invention.
