Description
Technical field
The present invention relates to mechanical float engineering device technique field, in particular to a kind of extension bar self-adapting float device.
Background technique
Mechanical float device is the important technology in modern industrial equipment, is to adapt to make up location of workpiece deviation and effectively solve
Certainly scheme.In the manufacturing process of automobile engine cylinder-body, to some processing holes will being sealed property detect, need to be deep into hole
Inside.Due to the not high hole of processing request position degree, there is deviation in the identical hole site on each cylinder body part, when going deep into hole
If the fixed a certain position of internal plugging device is constant, it is impossible to which the closure for adapting to all part same holes influences part
Processing and manufacturing process.
Summary of the invention
Technical problem to be solved by the invention is to provide one kind can hole site there are in the case where certain deviation into
Enter the floating installation of the position deviation in adaptive hole in hole.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is that:A kind of extension bar self-adapting float device,

Vacuum line body front end with boss be located at the centre bore of the driving cylinder and hollow fixation connecting rod is interior, tail end formed it is small
Diameter thin bar is goed deep into the centre bore of extension bar one end, and the outside of vacuum line body is equipped with fixing sleeve, and the fixing sleeve is through fixation
Bracket is connected with fixed connecting rod;Pressure spring is equipped between the vacuum line body and fixing sleeve;The fixing sleeve and extension bar warp
A pair of of concave spherical surface pad, convex spherical pad are connected.
The floating junction is adapted equipped with groove with vacuum line connected.
Gap is respectively equipped between the floating junction and vacuum line, between the vacuum line and fixing sleeve.
The end that the extension bar enters deeply into the pores is equipped with chamfering.
The beneficial effects of the invention are as follows:It can there are adapt to it in access aperture in the case where deviation and automatically partially in hole site
Difference.

Specific embodiment
Invention is further described in detail with reference to the accompanying drawings and detailed description:
As shown in Figure 1, a kind of extension bar self-adapting float device, including:Driving cylinder 1, floating junction 2, driving cylinder is fixed
Connecting rod 3, vacuum line 4, fixing sleeve 5, fixed bracket 6, pressure spring 7, concave spherical surface pad 8, convex spherical pad 9 and extension bar 10, floating connects
First 2, which are flexibly connected vacuum line, forms floating installation.One end that the driving cylinder 1 connects floating installation is equipped with centre bore, center
Outer wall of hole connects hollow fixation connecting rod 3;The floating installation includes the vacuum line 4 connecting with 2 end of floating junction, described
4 body front end of vacuum line with boss be located at the centre bore of the driving cylinder 1 and hollow fixation connecting rod 3 is interior, tail end formed it is small
Diameter thin bar is goed deep into the centre bore of 10 one end of extension bar, and the outside of vacuum line body is equipped with fixing sleeve 5, and the fixing sleeve 5 passes through
Fixed bracket 6 is connected with fixed connecting rod 3;Pressure spring 7 is equipped between the vacuum line body and fixing sleeve 5;5 He of fixing sleeve
Extension bar 10 is connected through a pair of of concave spherical surface pad 8, convex spherical pad 9.Floating junction 2 is equipped with groove and is adapted phase with vacuum line 4
Even.
There are certain gaps between floating junction 2 and vacuum line 4, deposit between the vacuum line 4 and fixing sleeve 5
There is pressure spring 7 between certain gap, the vacuum line 4 and the fixing sleeve 5, concave spherical surface pad 8 and convex spherical pad 9 are mutual
Cooperation makes mechanism form quick condition.
There is chamfering in 10 end of extension bar for closure, is easy in entrance hole.
Hole site there are in the case where certain deviation, the floating installation can adaptive hole position deviation, in access aperture.
The air-leakage test working principle in hole:
There is sealing ring in part in extension bar plugging device access aperture, after plugging device access aperture, sealing ring expansion with
Hole wall is sturdy, and the cavity for forming hole is isolated from the outside world, and the gas of certain pressure is filled in the cavity formed to hole, by airtight
Whether within the limits prescribed detecting instrument detects the amount of leakage of gas in the unit time.
