Description

A kind of extension bar self-adapting float device
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, Including floating installation and extension bar that driving cylinder, driving cylinder push, one end of the driving cylinder connection floating installation is equipped with center Hole, center outer wall of hole connect hollow fixation connecting rod;The floating installation includes the vacuum line being connected with floating junction end, 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.
Detailed description of the invention
Fig. 1 is a kind of extension bar self-adapting float apparatus structure schematic diagram of the present invention.
In figure:
1. 2. floating junction 3. of driving cylinder fixes connecting rod
4. 5. fixing sleeve 6. of vacuum line fixes bracket
7. 8. concave spherical surface of pressure spring pads 9. convex spherical pads
10. extension bar
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.
