Abstract
The utility model relates to one kind can be in the case where not changing Workpiece structure, the unthreaded hole attachment device that two workpiece with unthreaded hole are quickly connected, including two tension rings being separately positioned in two inner hole of workpiece, two turnbuckles being through in two tension ring inner holes respectively, taper fit is leaned between the inner hole of tension ring and the head of turnbuckle, tension ring is separate structure, two turnbuckles are through the both ends of U plate respectively and are mounted on U plate by nut and gasket, and two workpiece are linked together by the U plate, rapidly and efficiently can only have the workpiece of unthreaded hole to connect no threaded hole using the utility model, especially needing conductive situation, contact area can also be increased, improve conductive effect.
Description
Technical field
The utility model belongs to Quick Connect Kit technical field, more particularly to one kind can not change Workpiece structure
In the case of, unthreaded hole attachment device that two workpiece with unthreaded hole are quickly connected.
Background technique
Machine industry requires to connect two workpiece in many cases, and most common method is exactly to use
Be threadedly coupled, but in other instances, there is no screw thread on workpiece, or be threadedly coupled under certain operating conditions and inappropriate will cause it
Its secondary problem, for example in electroplating industry, hollow core rod product just needs two workpiece connecting one in plating
Block plating, and also without connection screw thread, its connection is not only to link up, but also want conductive, needs conduction this
In the case where, threaded connection is just less practical, because being threaded with gap, conduction can generate sparking, fever seriously, more seriously
Screw thread can be made to burn, connection is torn open not open, so that workpiece be caused to scrap.It, not only can be in consideration of it, need a kind of unthreaded hole attachment device
Workpiece design structure is not changed, and can connection rapidly and efficiently, moreover it is possible to improve the electric conductivity of contact area.
Summary of the invention
A kind of solution is provided the purpose of the utility model is to overcome the deficiencies in the prior art when not having screw thread
The unthreaded hole attachment device of connectivity problem between unthreaded hole.
The technical solution of the utility model is achieved in that a kind of unthreaded hole attachment device, including is separately positioned on two
Two tension rings in inner hole of workpiece, two turnbuckles being through in two tension ring inner holes respectively, the inner hole of tension ring and
Taper fit is leaned between the head of turnbuckle, tension ring is separate structure, and two turnbuckles are through the both ends of U plate simultaneously respectively
It is mounted on U plate by nut and gasket, and two workpiece is linked together by the U plate.
The hole taper of the tension ring is 1:10, and guarantees that, when turnbuckle is pulled outwardly, the outer diameter of tension ring is continuous
Swell, outer diameter and the inner hole of workpiece of tension ring the more rise the more tight.
The separate structure that the tension ring is 2 to 8 parts.
The head external conicity of the turnbuckle is 1:10.
When being pulled outwardly using turnbuckle, spacer is cased on the bolt body outer diameter of turnbuckle.
The good effect that the technical solution of the utility model generates is as follows: will can rapidly and efficiently not had using the utility model
The workpiece for having threaded hole there was only unthreaded hole connects, and is especially needing conductive situation, can also increase contact area, raising is led
Electric effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the unthreaded hole attachment device of the utility model.
It is marked in figure are as follows: 1, U plate;2, tension ring;3, turnbuckle;4, spacer;5, gasket;
6, nut.
Specific embodiment
As shown in Figure 1, a kind of unthreaded hole attachment device, including be separately positioned in two inner hole of workpiece two tension rings 2,
Two turnbuckles 3 being through in two 2 inner holes of tension ring respectively, are leaned between the inner hole of tension ring 2 and the head of turnbuckle 3
Taper fit, tension ring 2 are separate structure, and two turnbuckles 3 are through the both ends of U plate 1 respectively and pacify by nut 6 and gasket 5
Two workpiece are linked together on U plate, and through the U plate 1.
The hole taper of the tension ring 2 is 1:10, and guarantees that the outer diameter of tension ring 2 is not when turnbuckle 3 is pulled outwardly
Disconnected swell, outer diameter and the inner hole of workpiece of tension ring 2 the more rise the more tight.
The separate structure that the tension ring 2 is 2 to 8 parts.
The head external conicity of the turnbuckle 3 is 1:10.
When being pulled outwardly using turnbuckle 3, spacer 4 is cased on the bolt body outer diameter of turnbuckle 3.
This unthreaded hole attachment device, including tension ring 2, turnbuckle 3, spacer 4, U plate 1, gasket 5 and nut 6 form, and rise
Taper fit is leaned between tight ring 2 and turnbuckle 3, tension ring 2 can be divided into 2 to 8 parts according to requirements, and the number divided is more,
Tensioner effect is better, while turnbuckle is pulled outwardly, the continuous swell of the outer diameter of tension ring 2, and the outer diameter and workpiece of tension ring 2
Inner hole the more rises the more tight, and then two workpiece are connected with U plate 1.This unthreaded hole attachment device not only can connect end-face hole, can also be with
Connection has the deep hole of certain distance away from end face, and the aperture of two workpiece can also also can connect greatly with different, meets not
Same demand.
