On one element or it may be simultaneously present centering elements.When an element is known as " being connected to " another element, it can
To be directly to another element or may be simultaneously present centering elements.It should also be noted that, the utility model is real
Apply the positional terms such as left and right, upper and lower in example, be only each other relative concept or with the normal operating condition of product for reference
, and should not be regarded as restrictive.
As shown in Figure 1, a kind of dilator device provided by the embodiment of the utility model, comprising:
Expander 1, hand riveter 2, pressure controller 3 and air compressor 4, wherein expander 1 is inserted into hand riveter
In 2 muzzle, hand riveter 2 is connect by coupling tracheae with air compressor 4, the high pressure gas provided by air compressor 4,
It can make hand riveter 2 that expander 1 quickly be carried out drawing；In addition, pressure controller 3 is arranged on connection tracheae, to air
The pressure that compressor 4 is linked into hand riveter 2 is controlled, to realize the controller control tracheae to the pulling capacity of hand riveter 2, pressure
The setting of controller 3 and air compressor 4 etc. is more conventional technology in the prior art, is no longer done herein superfluous
It states.
As shown in Fig. 2, Fig. 2 is that a kind of structure of the Workpiece structure provided by the embodiment of the utility model before being fixedly connected is shown
It is intended to.Wherein, the first circular hole 51 and the second circular hole are had on the first workpiece 5 and second workpiece 6, on the first workpiece 5
The marginal portion of first circular hole 51 is translated into through hole flanging process and erects side by one circular hole 51, i.e. on the first circular hole 51 of the first workpiece 5
Protrude the setting marginal portion 52 of hollow cylinder；The outer diameter for erectting marginal portion 52 is slightly less than or equal in the second circular hole
Diameter, so that the setting marginal portion 52 on the first workpiece 5 is inserted into the second circular hole of second workpiece 6.
As shown in figure 3, Fig. 3 is a kind of use schematic diagram of expander provided by the embodiment of the utility model.By first
Workpiece 5 mutually fits with second workpiece 6, and the setting marginal portion 52 on the first workpiece 5 is made to be inserted on the second circular hole it
Afterwards, expander 1 is passed through from the first circular hole 51 of the first workpiece 5.Wherein, expander 1 can be the pole body of a strip,
One end of expander 1 is provided with the ball 11 of protrusion, and the other end of expander 1 passes through the setting marginal portion 52 of the first workpiece 5
And first circular hole 51, and be stuck in outside the first workpiece 5；In addition, the diameter of ball 11 set on expander 1 is greater than first
The internal diameter of circular hole 51, therefore one end of expander 1 is stuck in and is erect outside marginal portion 52 due to the effect of ball 11, Wu Fatong
Cross setting marginal portion 52 and the first circular hole 51.The first circular hole 51 is passed through in the other end of expander 1 and is stuck in the first circle
After hole 51 is outer, the other end of expander 1 is inserted into the muzzle of hand riveter 2, and guarantee the other end and hand riveter of expander 1
Then 2 connection starts hand riveter 2, hand riveter 2 carries out quick drawing to expander 1, i.e., by expander 1 toward the first circular hole 51
Outer pull-out.Under the huge pulling force effect of hand riveter 2, the ball 11 of one end of expander 1 and protrusion is from erectting marginal portion
It 52 and first passes through in circular hole 51, finally pulled into outside the first circular hole 51, be detached from the first workpiece 5 and second workpiece 6.Due to
The diameter of ball 11 is greater than the internal diameter for erectting marginal portion 52 and the first circular hole 51, and therefore, ball 11 is by erectting edge
When part 52 and the first circular hole 51, marginal portion 52 and 51 spreading of the first circular hole can will be erect, erect marginal portion 52 and exist
The crowded power effect of ball 11 is lower, and deformation occurs and spreading outward, and the second circular hole of second workpiece 6 is placed on setting marginal portion 52
Outside, therefore setting marginal portion 52 is inclined by spreading and is tightly embedded on the inside of the second circular hole, that is, realizes the perpendicular of the first workpiece 5
The clamping of vertical marginal portion 52 and the second circular hole of second workpiece 6, the first workpiece 5 are fixedly connected on one with second workpiece 6.
As shown in figure 4, Fig. 4 is the structure after a kind of stretched device spreading of Workpiece structure provided by the embodiment of the utility model
Schematic diagram.Wherein, the vertical edge part of the first workpiece 5 is by after spreading, and tightly inlay card is in the second circular hole of second workpiece 6
Interior, the first workpiece 5 of realization is fixedly connected with second workpiece 6.By using expander 1 by the first workpiece 5 and second workpiece 6 into
The mode that row is fixedly connected, can remove the use of rivet from, only be cooperated by the deformation between the first workpiece 5 and second workpiece 6
Being fixedly connected between the first workpiece 5 and second workpiece 6 can be realized, and expander 1 can repeatedly use, and save into
This；In addition, being fixedly connected for the first workpiece 5 and second workpiece 6 can be completed after expander 1 drawing out using hand riveter 2,
It is simple and convenient, it is high-efficient, without carrying out the operation such as orthopedic to the first workpiece 5 and second workpiece 6, be conducive to rapid batch
Processing.
It is worth noting that, in the utility model embodiment, in order to guarantee expander 1 in the first workpiece of spreading 5 and
Itself does not occur indeformable when second workpiece 6, and the hardness of expander 1 is greater than the hard of the first workpiece 5 and second workpiece 6
Degree.Under normal conditions, the first workpiece 5 and second workpiece 6 are sheet metal component, and hardness is not high；Expander 1 then can be using high speed
Steel is made, and has the characteristics that high rigidity, high-wearing feature, in order to which expander 1 can repeatedly use.In addition, in order to guarantee
Successfully expander 1 can be drawn out, the pulling force of hand riveter 2 is specifically as follows 0.1 to 0.5MPa, is guaranteeing to draw out
While expander 1, guarantee that expander 1 is not easy to be pulled off or draw deformation.
Preferably, in the utility model embodiment, according to specific processing scene, ball 11 on expander 1 it is straight
Diameter can be bigger than the internal diameter of first circular hole 51 by 1 to 5mm, depending on the first circular hole 51 inner diameter size and take different diameters
Value.
The embodiments of the present invention are described above in conjunction with attached drawing, but the utility model is not limited to
The specific embodiment stated, the above mentioned embodiment is only schematical, rather than restrictive, this field it is common
Technical staff is not departing from the utility model aims and scope of the claimed protection situation under the enlightenment of the utility model
Under, many forms can be also made, these are belonged within the protection of the utility model.
