Abstract
The utility model provides a kind of punching porcupine roller, including axis, mandrel cylinder and porcupine roller cylinder, axis is equipped with by bearing in mandrel cylinder, the mandrel cylinder is located in porcupine roller cylinder, mandrel cylinder and porcupine roller cylinder are clearance fit, and the both ends of fit clearance 0.05-0.1mm, mandrel cylinder are equipped with incline bench, porcupine roller cylinder both ends are equipped with O-ring and taper liner, are then equipped with gland by screw；Preferably, the bevel angle of the incline bench is 30.Mandrel cylinder both ends are arranged to 30 incline bench by the utility model; interference fit between mandrel cylinder and porcupine roller cylinder is changed to clearance fit; and mandrel cylinder and porcupine roller cylinder are closely linked by the expanding force of both ends O-ring; since O-ring belongs to soft object; tensioner will not cause porcupine roller cylinder to deform on porcupine roller cylinder, and it is quick convenient to assemble, and protect operator's personal safety; it improves work efficiency, saves material and assembly costs.
Description
Technical field
The utility model belongs to lid equipment technical field processed, relates in particular to a kind of punching porcupine roller.
Background technique
Punching porcupine roller is used after cylinder with a needle is fitted together with mandrel roller group, and the wall thickness of porcupine roller cylinder is relatively thin, generally
In 5mm or so, key joint can not be used, is usually all that porcupine roller cylinder and mandrel are fitted together into use using interference fit.Due to
It has been covered with sharp syringe needle on porcupine roller cylinder, it is very sharp, syringe needle is easily touched off in assembling process and hurts the hand of operator.
Porcupine roller cylinder barrel is very thin, can not be tapped and is encased on mandrel with hammering method, such as heated attire method with flame, then cause
Syringe needle annealing is not available, and can only be scrapped.Usually assembling is all that porcupine roller cylinder is put into oil, is assembled using warm dress method.Due to needle
Roller barrel is relatively thin, and oil heating is generally at 300 DEG C or so, once built-up time is too long, syringe roller cools off contractions, and is difficult to smooth
Ground is set in together with mandrel, and in order to solve this problem, we devise flexible material tensioner method to assemble punching porcupine roller.
Summary of the invention
The utility model provides a kind of punching porcupine roller, solves lacking for the punching porcupine roller assembly difficulty in background technique
Point.
The technical solution of the utility model is achieved in that a kind of punching porcupine roller, including axis, mandrel cylinder and porcupine roller cylinder,
Axis is equipped with by bearing in mandrel cylinder, the mandrel cylinder is located in porcupine roller cylinder, and mandrel cylinder and porcupine roller cylinder are clearance fit, between cooperation
Gap is 0.05-0.1mm, and the both ends of mandrel cylinder are equipped with incline bench, and porcupine roller cylinder both ends are equipped with O-ring and taper liner, then pass through spiral shell
Nail is equipped with gland；
Preferably, the bevel angle of the incline bench is 30.
The beneficial effects of the utility model are: mandrel cylinder both ends are arranged to 30 incline bench by the utility model, by core
Interference fit between beam barrel and porcupine roller cylinder is changed to clearance fit, and by the expanding force of both ends O-ring by mandrel cylinder and porcupine roller
Cylinder is closely linked, and since O-ring belongs to soft object, tensioner will not cause porcupine roller cylinder to deform on porcupine roller cylinder, assembling
It is quick convenient, operator's personal safety is protected, improves work efficiency, saves material and assembly costs.
Detailed description of the invention
Fig. 1 is the main view of the utility model；
Fig. 2 is the structural schematic diagram of the utility model mandrel cylinder；
Fig. 3 is the perforating needle roll structure schematic diagram before improving.
Part explanation: 1, axis, 2, mandrel cylinder, 3, porcupine roller cylinder, 4, gland, 5, taper liner, 6, screw, 7, O-ring, 8, benchboard
Rank, 9, bearing.
Specific embodiment
For a better understanding and implementation, 1-2 is further described the utility model with reference to the accompanying drawing: a kind of punching
Porcupine roller, including axis 1, mandrel cylinder 2 and porcupine roller cylinder 3, mandrel cylinder 2 is interior to be equipped with axis 1 by bearing 9, and mandrel cylinder 2 is located in porcupine roller cylinder 3,
Mandrel cylinder 2 and porcupine roller cylinder 3 are clearance fit, and fit clearance 0.05-0.1mm, the both ends of mandrel cylinder 2 are equipped with 30 benchboard
Rank 8,3 both ends of porcupine roller cylinder are equipped with O-ring 7 and taper liner 5, are then equipped with gland 4 by screw 6.
The both ends of mandrel cylinder 2 are processed into 30 ° of incline benches 8 first, by the mistake between original mandrel cylinder 2 and porcupine roller cylinder 3
Cooperation of being full of is changed to clearance fit, fit clearance 0.07mm, and axis 1 and bearing 9 are installed in advance, altered after porcupine roller cylinder 3 is disposed vertically
Enter 2 assembly of mandrel cylinder, then syringe roller 3 is horizontally arranged (lower part setting cushion), touches 2 assembly of mandrel cylinder in place with hand.
O-ring 7 successively is loaded at both ends, is packed into taper liner 5, after loading onto gland 4, equably tightening screw 6 squeezes O-ring 7
Mandrel cylinder 2 and porcupine roller cylinder 3 are bound tightly together by compressive strain, and since 3 transmission force of porcupine roller cylinder is seldom, O-ring 7 belongs to soft
Object, tensioner will not cause porcupine roller cylinder 3 to deform on porcupine roller cylinder 3, and the expanding force of both ends O-ring 7 is reliably by mandrel cylinder 2 and needle
Roller 3 is combined together.
It is gap-matched porcupine roller cylinder 3 and rotates disc, of less demanding with 3 center line concentricity of mandrel cylinder, error is in 1mm
It can receive, requirement is fully achieved, be fully reflected on safety and reliability.
