Description

A kind of encircling type positioning and clamping mechanism

Technical field

The present invention relates to a kind of encircling type positioning and clamping mechanism, for positioning and locking during hollow pipe fitting retaining wall on slope, belong to In pipe fitting processing technique field.

Background technology

The retaining wall on slope of hollow pipe fitting is completed by lathe or some other special retaining wall on slope equipment mostly now.If By lathe, the groove of hollow pipe fitting is processed, not only floor space is big, and positioning and clamping mechanism used is generally chuck, This requires that pipe fitting may move in process, cannot meet job requirement in the case that pipe fitting is fixing;According to other Some special retaining wall on slope equipment be processed, then the location locking mechanism of these retaining wall on slope equipment clamping when do not have Real time data is fed back, if clamping puts in place and can not intuitively reflect, thus positioning precision is not high.

Based on the above state of the art, the applicant specially develops a kind of encircling type positioning and clamping mechanism.

Content of the invention

The goal of the invention of the present invention is: for above-mentioned problem, provide a kind of encircling type positioning and clamping mechanism, can So that easily hollow pipe fitting is carried out with positioning clamping, and positioning precision can be improved.

The technical solution used in the present invention is such that

A kind of encircling type positioning and clamping mechanism, including support guard shield, short stroke linear motion drive component, taper expansion set, fixation Set, expansion sleeve and locking tapered sleeve, described support guard shield lower end is connected with the flange plate bolt of fixing set upper side, described taper expansion set It is downwardly in fixed cover, setting at least two on described fixed cover inwall is stuck in the positioning table in the expansion or contraction joints of taper expansion set Rank, the short stroke linear motion that taper expansion set upper end edge ring flange is connected for a week vertically arranged at least two with support guard shield drives Assembly, described expansion sleeve inserts in taper expansion set from the bottom up, between described locking cone set insertion fixed cover and taper expansion set simultaneously It is connected with fixed cover lower end of the bolt by ring flange.

Technique scheme mainly solves the problems, such as quick positioning, locking, and it is little to have a whole organization volume, easy to operate Feature.Positioning step is stuck on the locating surface on pipe fitting thus realizing axially position.

Preferably, described fixed cover arranges pressure transducer on its ring flange.After setting pressure transducer, permissible The suffered pressure after the promotion by short stroke linear motion drive component of real-time monitoring fixed cover, in order to determine whole mechanism Coupling mechanism force whether up to standard.

Preferably, being symmetrical arranged within one week two short stroke linear motion driving groups in described taper expansion set upper flanges disk Part.Short stroke linear motion drive component can be cylinder, oil cylinder, the form of motor+leading screw, is symmetrical arranged two, Ke Yibao The symmetry of card stress, effectively improves positioning precision.

Preferably, three positioning steps of setting in a week on described fixed cover inwall.It is the most steady that positioning step arranges three Fixed, can guarantee that positioning precision most.On described positioning step, the detection switch that puts in place is set, for detecting whether whole mechanism puts Put and put in place.

In sum, due to employing technique scheme, the invention has the beneficial effects as follows:

1. mechanism installs afterwards and pipe fitting becomes an entirety, greatlys save required space when installing and working, Adapt to narrow occasion;

2. only need to location locking mechanism lifting is inserted on workpiece and can achieve axially position and automatic centering, install and The operation of dismounting is very simple, quick;

3. pair heart high precision, the concentricity under the cooperation of taper expansion set, expansion sleeve, locking tapered sleeve controls, to heart precision ≤0.025mm;

4. reliable operation, the detection switch that puts in place and pressure transducer real-time feedback information, accomplish real-time monitoring.

Brief description

Fig. 1 is the main view profile of the present invention.

Fig. 2 is the top view (its a-a sectional view is shown in Fig. 1) of the present invention.

Fig. 3 is the perspective view of taper expansion set shown in labelling 3 in Fig. 1.

In figure labelling: 1 is support guard shield, 2 is short stroke linear motion drive component, and 3 is taper expansion set, and 4 is fixed cover, 5 is expansion sleeve, and 6 is locking tapered sleeve, and 7 is the detection switch that puts in place, and 8 is pipe fitting, and 31 is swelling seam, and 41 is positioning step.

Specific embodiment

Below in conjunction with the accompanying drawings, the present invention is described in detail.

Embodiment:

As shown in Figure 1, 2, 3, a kind of encircling type positioning and clamping mechanism, including support guard shield 1, short stroke linear motion drive component 2nd, taper expansion set 3, fixed cover 4, expansion sleeve 5 and locking tapered sleeve 6, the ring flange of described support guard shield 1 lower end and fixed cover 4 upper end Bolt connection, described taper expansion set 3 is downwardly in fixed cover 4, and setting at least two on described fixed cover 4 inwall is stuck in taper Positioning step 41 in the expansion or contraction joints 31 of expansion set 3, taper expansion set 3 upper end edge ring flange one week vertically arranged at least two and support The short stroke linear motion drive component 2 that guard shield 1 connects, described expansion sleeve 5 inserts in taper expansion set 3 from the bottom up, described lock It is connected with fixed cover 4 lower end of the bolt between tight tapered sleeve 6 insertion fixed cover 4 and taper expansion set 3 and by ring flange.

Described fixed cover 4 arranges pressure transducer (8) on its ring flange.In described taper expansion set 3 upper flanges disk one It is symmetrical arranged two short stroke linear motion drive components 2 week.Three positioning steps of setting in a week on described fixed cover 4 inwall 41.The detection switch (7) that puts in place is arranged on described positioning step.

As shown in fig. 1, the upper end of pipe fitting 9 offers chute corresponding with positioning step 41, so that mechanism can be from Top to bottm hang in installation.

The specific works mode of the present invention:

After whole mechanism installs, lifted and be inserted in pipe fitting 9 to be processed, until positioning step 41 blocks pipe fitting 9 slope Whether the cylindrical step at mouthful, be in place by the data validation mechanism that the detection switch 7 that puts in place is fed back.After being in place, Short stroke linear motion drive component 2 works, and promotes taper expansion set 3 to move down.The conical surface of taper expansion set 3 is to expansion sleeve 5 He The conical surface of locking tapered sleeve 6 is extruded, and finally forces expansion sleeve 5 conical surface to contract, encircles the outer wall of locking pipe fitting 9, period Can encircle whether pressure reaches locking standard by the data validation that pressure transducer 8 feeds back.To the process finishing of pipe fitting 9 it Afterwards, short stroke linear motion drive component 2 works, and drives taper expansion set 3 to move upwards, and the conical surface of taper expansion set 3 is retracted, no longer The conical surface of expansion sleeve 5 and locking tapered sleeve 6 is extruded, the conical surface of final expansion sleeve 5 rebounds, no longer encircle outside locking pipe fitting Wall, the most whole mechanism hangs out.
