Description
Technical Field
The utility model belongs to the technical field of pipeline mould's high-speed joint, especially, relate to a high-speed joint device for fibre winding steel core mould.
Background
In recent years, the application of medium-high pressure glass reinforced plastic pipes as ground oil collecting pipes and water injection pipes and underground oil pipes in the field of oil exploitation is more and more common. The diameter of these pipes is usually 100mm or less and the length is 9m or more. At present, a multi-station fiber winding machine is mostly adopted for producing the high-pressure glass steel tube, and an online internal curing method is adopted to improve the production efficiency.
Because the pipe die is a slender shaft and is easy to bend, the bent slender steel core die can influence the winding of fibers, and therefore, the slender steel core die needs to be tensioned in the production process so as not to bend.
The existing tensioning method is generally to fix one end (head) of a slender shaft steel core mold by adopting a fixed connection form such as a flange, etc., connect the other end (tail end) of the steel core mold with a tailstock, and tension the tailstock by a hydraulic cylinder, etc. In order to release the cured glass fiber reinforced plastic pipe from the steel core mold, the connection between the tail end of the steel core mold and the tailstock needs to be frequently connected and detached. The conventional connection method adopts a pin shaft for fixed connection, and the fixed connection mode is extensive, manual disassembly is required, quick connection and disassembly cannot be realized, and the production efficiency is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the problem among the prior art, provide a quick connecting device for fibre winding steel mandrel.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a quick connecting device for fibre winding steel mandrel, it includes connecting cylinder, sleeve, steel mandrel and location bearing ball, the connecting cylinder has a plurality of connecting holes along the circumferencial direction equipartition, all be provided with location bearing ball in a plurality of connecting holes, the sleeve is the structure of becoming internal diameter, links to each other with the connecting cylinder through little internal diameter end, the sleeve sets up in the outside of connecting cylinder and along connecting cylinder axial displacement, the hoop spread groove has been seted up on the steel mandrel, the spread groove is convex structure, the steel mandrel passes through the spread groove and links to each other with the connecting cylinder with the cooperation of location bearing ball.
Furthermore, the number of the connecting holes is three.
Further, the connecting cylinder and the sleeve are connected by screw threads.
Furthermore, the connecting cylinder and the sleeve are connected through a sliding rail.
Furthermore, the positioning bearing ball is clamped in the connecting hole.
Furthermore, the connecting cylinder is fixedly connected with an external machine tool.

Detailed Description
The technical solution in the embodiment of the present invention will be clearly and completely explained below with reference to the drawings in the embodiment of the present invention.
The embodiment is described with reference to fig. 1 to 4, and a quick connection device for a fiber winding steel core mold comprises a connection cylinder 1, a sleeve 2, a steel core mold 3 and a positioning bearing ball 4, wherein a plurality of connection holes 5 are uniformly distributed in the connection cylinder 1 along the circumferential direction, the positioning bearing ball 4 is arranged in each of the plurality of connection holes 5, the sleeve 2 is of a variable inner diameter structure and is connected with the connection cylinder 1 through a small inner diameter end, the sleeve 2 is arranged on the outer side of the connection cylinder 1 and moves along the axial direction of the connection cylinder 1, a circumferential connection groove 6 is formed in the steel core mold 3, the connection groove 6 is of an arc-shaped structure, and the steel core mold 3 is connected with the connection cylinder 1 through the matching of the connection groove 6 and the positioning bearing ball 4.
This embodiment connecting hole 5 quantity is three, connecting cylinder 1 and sleeve 2 pass through threaded connection or through sliding rail connection, 4 joints of location bearing ball are in connecting hole 5, connecting cylinder 1 and outside lathe fixed connection. During installation, the sleeve 2 moves towards the front end, so that the positioning bearing ball 4 can move upwards to enter the large inner diameter position of the sleeve 2, the steel core die 3 is installed in the connecting cylinder 1, the positioning bearing ball 4 is extruded to move upwards, when the connecting groove 6 on the steel core die 3 corresponds to the positioning bearing ball 4, the positioning bearing ball 4 enters the connecting groove 6, then the sleeve 2 is moved axially so that the small diameter end of the sleeve is located at the connecting hole 5, the positioning bearing ball 4 inside is prevented from moving upwards, and therefore the steel core die 3 is connected and fixed quickly. When the steel core mold 3 is disassembled, the sleeve 2 is reversely moved, and the steel core mold 3 is pulled to enable the positioning bearing ball 4 to move upwards to be separated from the connecting groove 6, so that the steel core mold 3 is disassembled quickly.
The above description is made in detail on the quick connection device for the filament winding steel core mold provided by the present invention, and the principle and the implementation mode of the present invention are explained by applying specific examples, and the description of the above examples is only used to help understanding the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
