Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
The utility model provides a kind of copper sheathing pulling attachment of cylinder cover, as shown in figure 1, it includes lifting rod 10, cone
Shape tensioner is first 20, taper cutting ferrule 30 and reference seat 40, wherein, the lifting rod 10 is screw mandrel.
The reference seat 40 is provided with multiple threaded locating holes being correspondingly arranged with cylinder cover, and the reference seat 40 passes through spiral shell
Mother is through threaded locating hole locking positioning on cylinder cover.It is logical with female installation that one is further opened with the reference seat 40
Hole, the threaded one end of lifting rod 10 fit through the through hole and are fixedly connected with taper tensioner first 20, the lifting rod 10
The other end is provided with rotational handle 11.And thread bush holds portion 12 equipped with proficiency on the body of rod of lifting rod 10 of the upper end of reference seat 40,
The outer wall of the Handheld Division 12 is rubbing surface.
The taper cutting ferrule 30 is sleeved in the taper tensioner first 20, as depicted in figs. 1 and 2, the smaller one end of its diameter
Port diameter be less than taper tensioner first 20 in the smaller one end of diameter diameter, and less than copper sheathing 50 choose end port in
Footpath；The maximum gauge of the taper tensioner first 20 is more than copper sheathing 50 and chosen the port inner diameter at end；Meanwhile the as shown in figure 3, cone
The port of the smaller one end of diameter extends upward multiple expansion slots 31 along sleeve wall in shape cutting ferrule 30, and the expansion slot 31 is circumferential
It is uniformly distributed setting.In addition, the both sides of the port of the smaller one end of diameter are arranged with latch part 32, institute in the taper cutting ferrule 30
State latch part 32 and extended radially outwardly from the outer wall of taper cutting ferrule 30 and is provided projectingly.
When defective copper sheathing 50 is chosen in needing to cylinder cover, first by lifting rod 10 by taper cutting ferrule 30
Insert in the port at the end of choosing of copper sheathing 50, reference seat 40 is then passed through into threaded locating hole locking positioning in cylinder by nut
Cover, rotary motion handle 11, rotate down lifting rod 10, promote taper tensioner first 20 to move downward, so as to conic clamp
