Embodiment 1

[0036] Such as Figure 1-Figure 4 As shown, a sealing clamping mechanism, including:

[0037] The fixed chuck 1 is an annular disc, the end face of the fixed chuck 1 is used to install the clamping assembly 2, and a through hole 101 is formed in the center of the annular disc for passing through the tubular workpiece 11, The diameter of the through hole 101 can be equal to the diameter of the workpiece 11 or larger than the diameter of the workpiece 11 .

[0038] There are sixteen clamping assemblies 2 arranged in a circular array on the fixed chuck 1, including a support rod 201, a clamping jaw 202 driven by the support rod 201 and a synchronous pulley 203, and the support rod 201 is rotationally connected with the fixed chuck 1 , the support rod 201 is composed of a cylindrical section 2011 and a prism section 2013, the cross section of the prism section 2013 is rectangular, and the fixed chuck 1 is provided with sixteen shaft holes 12 in a circumferential array, and the cy...

Embodiment 2

[0045] If the jaws 202 extend in the same direction from the end close to the support rod 201 to the end far away from the support rod 201, it will cause the free end sides of the adjacent jaws 202 to squeeze each other, and a larger initial force is required at this time. Only then can the jaws 202 be opened and separated, and the jaws 202 cannot be evenly opened. For this reason, the structure of the jaws 202 is improved in this embodiment. Specifically, the free end of the jaws 202 has a direction of rotation toward the jaws 202. Extended hook portion 15. The tightening rotation direction of the clamping jaw 202 refers to the rotation direction of the clamping jaw 202 during the tightening process of the mechanism, such as Figure 7 As shown, the extension direction of the hook portion 15 is opposite to the direction of the tip of the free end of the jaw 202, and the hook portion 15 is used to connect with the tip of the adjacent jaw 202, which can avoid the side walls of t...

Embodiment 3

[0047] In this embodiment, the clamping jaw 202 is changed from a rigid material to a flexible material, for example, rubber material or PTEE material, etc. can be used. The deformation can better realize the surface contact, and the clamped product can also be polygonal, which gets rid of the limitations of the traditional clamping mechanism.

[0048] In order to reduce maintenance costs, the jaws 202 in this embodiment preferably adopt a quick-change split structure, such as Figure 5 and Figure 7 As shown, the jaw 202 is composed of a brake blade 2021 and a sealing blade 2022, the brake blade 2021 is connected with the support rod 201, the sealing blade 2022 is connected with the brake blade 2021, and the ends of several sealing blades 2022 are suitable to form a closed column Mounting surface 5. At this time, it is only necessary to make the sealing blade 2022 of a flexible material. When the sealing blade 2022 is worn out, only the sealing blade 2022 needs to be replac...

Abstract

The invention discloses a sealing clamping mechanism. The sealing clamping mechanism comprises a fixed chuck, a synchronous belt and a plurality of clamping assemblies arranged on the fixed chuck in a circumferential array manner. Each clamping assembly comprises a supporting rod, a clamping jaw driven by the supporting rod to rotate and synchronous belt wheels, and each synchronous belt is arranged at the peripheries of the synchronous belt wheels in a sleeving manner. One supporting rod is in transmission connection with a driving assembly, and when the clamping assemblies are tightened, the free end of each clamping jaw gradually gets close to a center shaft of the fixed chuck and forms a circumferentially-closed columnar clamping face in a surrounding manner; and when the clamping assemblies are opened, the free end of each clamping jaw is gradually far away from the center shaft of the fixed chuck. Linkage clamping is completed through cooperation of the belt wheels and the synchronous belt, when the driving assembly rotates, the free end of each clamping jaw is gradually tightened or opened, so that a workpiece is clamped and loosened, the clamping force is uniform, and deformation of a clamped product caused by uneven stress is avoided.

Description

technical field [0001] The invention relates to the technical field of clamping of tubular workpieces, in particular to a sealing clamping mechanism, which is mainly used for clamping pipelines in glue pouring, glue spreading and glue dispensing industries. Background technique [0002] With the rapid development of science and technology in today's society, the clamping, positioning and scope of application of products have new requirements and have risen to a new height. In the glue filling, gluing and dispensing industries, the glue output equipment usually delivers glue to other sealing equipment through flexible or rigid delivery pipelines. In order to avoid the sloshing of the delivery pipeline, it is necessary to use clamps to clamp or fix the delivery pipe The way (that is, the workpiece), the traditional clamping scheme often clamps the workpiece through the jaws and the clamp surface, but a series of problems will cause the clamping effect to be unsatisfactory: ...
