Description

Mandrel structure of pipe fitting sealing ring assembling machine

Technical Field

The utility model belongs to the technical field of stainless steel pipe production equipment, and relates to a mandrel structure of a pipe fitting sealing ring assembly machine.

Background

When the pipe fitting is connected, the pipe fitting is often sealed through the sealing ring, and the pipe fitting is internally provided with a convex ring for installing the sealing ring, and the inner diameter of the convex ring is larger than that of the pipe fitting, so that the pipe fitting is required to be plugged into the pipe fitting after being pinched and deformed, the sealing ring is difficult to install, a large amount of labor is consumed, and the sealing ring assembly machine is produced.

The mandrel structure of the existing sealing ring assembly machine is shown in fig. 3 and 4, and comprises an outer cylinder 1 and an inner rod 2 which is slidably connected in the outer cylinder 1, wherein a pair of hooks 3 used for hooking a sealing ring are fixed at the top of the outer cylinder 1, a mounting screw 4 is arranged at the bottom of the inner rod 2, a top cap 5 and a limiting cap 6 are sequentially fixed at the top of the inner rod 2 from top to bottom, and through grooves used for avoiding the hooks 3 are formed in the outer peripheral surfaces of the top cap 5 and the limiting cap 6. A pair of hanging rods 7 are further fixed below the limiting cap 6 on the upper portion of the inner rod 2, and an avoiding groove 8 for avoiding the hanging rods 7 is formed in the top of the outer cylinder 1. When the inner rod 2 is contracted, the hook 3 can just splice the top cap 5 and the limit cap 6 into a complete round shape, and a groove for sleeving a sealing ring is formed between the hook and the top cap 5. When the sealing ring assembly machine works, the material guide mechanism of the sealing ring assembly machine sends the sealing to the front of the mandrel, the mandrel stretches forwards, and the sealing ring is sleeved in the groove; then, the inner rod 2 extends outwards, the hanging rod 7 on the inner rod is hung at the two ends of the seal to stretch forwards, the other two ends of the hanging hook 3, which are hung on the sealing ring, continue to keep the original position, further deform the inner rod, reduce the outer diameter, further extend into the pipeline and are installed in the convex ring.

However, the hook 3 of the mandrel with the structure needs to bear a certain tensile force in the working process, so that the hook 3 is easy to break and damage, and after the hook 3 breaks, the outer cylinder 1 of the mandrel needs to be replaced entirely, so that the equipment maintenance cost is increased.

Disclosure of Invention

The utility model aims to solve the problems in the prior art, provides a pipe fitting socket detection device, and aims to optimize the structure of an existing sealing ring Zheng Peiji mandrel and further reduce equipment maintenance cost.

The aim of the utility model can be achieved by the following technical scheme: the mandrel structure of the pipe fitting sealing ring assembly machine is characterized by comprising an outer barrel and a hook, wherein two mounting grooves are formed in the inner wall of the upper part of the outer barrel, and a plurality of fixing holes are formed in the bottoms of the mounting grooves; the hook comprises a hook body and a mounting rod, wherein the mounting rod is matched with the mounting groove, and a plurality of protruding blocks matched with the fixing holes are arranged on the mounting rod.

The utility model has the advantages that:

the mandrel changes the original integrated outer cylinder into the outer cylinder and the assembled hook, when the hook is broken, only the hook needs to be replaced, the whole outer cylinder does not need to be replaced, and the maintenance cost of equipment is reduced.

In the figure, 1, an outer cylinder; 11. a mounting groove; 12. a fixing hole; 2. an inner rod; 3. a hook; 31. a mounting rod; 32. a bump; 4. installing a screw; 5. a top cap; 6. a limit cap; 7. a hanging rod; 8. avoiding the groove.

Detailed Description

The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.

As shown in fig. 1 and 2, a mandrel structure of a pipe fitting sealing ring assembly machine comprises an outer cylinder 1 and a hook 3, wherein two mounting grooves 11 are formed in the inner wall of the upper part of the outer cylinder 1, and a plurality of fixing holes 12 are formed in the bottom of each mounting groove 11; the hook 3 comprises a hook body and a mounting rod 31, the mounting rod 31 is matched with the mounting groove 11, and a plurality of protruding blocks 32 matched with the fixing holes 12 are arranged on the mounting rod 31.

When the mandrel is assembled, the mounting rods 31 of the two hooks 3 are firstly placed in the corresponding mounting grooves 11, then the convex blocks 32 on the mounting rods 31 are placed in the corresponding fixing holes, finally the inner rod 2 is inserted into the outer cylinder 1, and the hooks 3 are fixed on the outer cylinder 1 under the extrusion limit of the inner rod 2. The mandrel changes the original integrated outer cylinder 1 into the outer cylinder 1 and the assembled hook 3, when the hook 3 breaks, the hook 3 only needs to be replaced, the whole outer cylinder 1 does not need to be replaced, and the maintenance cost of equipment is reduced.

The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the utility model or exceeding the scope of the utility model as defined in the accompanying claims.
