The circular hole of glass bar phase configuration, the cup is inner to be provided with the tapered slope hole being engaged with double end bushing one end, the connection
The upper end of chuck is used to be connected with cup, and the bellmouth being engaged with the double end bushing other end is provided with lower end.
By above-mentioned technical proposal, the both ends of the double end bushing are circumferentially uniformly provided with fluting.
By above-mentioned technical proposal, the width of the fluting is 1-3 ㎜.
By above-mentioned technical proposal, the tapered slope at the double end bushing both ends is symmetrically arranged structure, its upper end it is outer
Footpath from top to bottom becomes larger.
By above-mentioned technical proposal, the angular range of the tapered slope of the double end bushing is 3 °~10 °.
By above-mentioned technical proposal, the cup lower end outer wall is external screw thread, and the upper end inwall of the connecting clip is cylinder
Shape inner bolt hole, screw-type connecting clip is formed, its lower end is the bellmouth that internal diameter reduces successively from top to bottom, in connecting clip
Outer wall offers multiple grooves vertically,.
By above-mentioned technical proposal, stepped hole, the stepped hole are offered above tapered slope hole in the cup
Internal diameter is up-small and down-big, and the step of stepped hole is used to realize the spacing of glass bar.
By above-mentioned technical proposal, the connecting clip can be that the connected mode of buckle is connected with cup.
During installation, double end bushing is inserted in glass bar to be held from top to bottom first, both size and specification are prior
Measurement, selects suitable types, ensures to be mutually matched, elastic suitable；Then glass bar upper end is inserted in cup, then double end is served as a contrast
Set is promoted in cup, holds out against double end bushing from the bottom up, ensures that double end bushing ramp fully contacts with cup outer inclined-plane；Finally
The connecting clip for including tapered slope hole is put to the lower end tapered slope of double end bushing from the bottom up, tightening chuck, that is, completed.
Having the beneficial effect that acquired by the present invention：The present invention is simple in construction easy to process, by setting tapered slope to realize
The centering of glass bar, and centering effect is good, it is easy to operate without manually adjusting, further increase operating efficiency；
After setting notching construction stress on double end bushing, it is easy to close up, more conducively clamps workpiece, improves the resistance that rubbed between bushing and workpiece
Power, longer and heavier workpiece can be clamped.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of automatic centering glass bar clamping device is present embodiments provided, including double end bushing 3, cup
1st, connecting clip 4.As Figure 2-3, the both ends outer wall of the double end bushing 3 is tapered slope 302, the both ends of double end bushing 3
Tapered slope be symmetrically arranged structure, the external diameter of its upper end from top to bottom becomes larger, the endoporus of double end bushing 3 be with
The circular hole 303 of the phase configuration of glass bar 2, the cup 1 is inner to be provided with the tapered slope hole being engaged with the one end of double end bushing 3, institute
State in cup and offer stepped hole above tapered slope hole, the stepped hole internal diameter is up-small and down-big, the step of stepped hole
For realizing the spacing of glass bar 1, the cup lower end outer wall is external screw thread.As illustrated in figures 4-5, the connecting clip 4 is upper
End inwall is cylindric inner bolt hole 401, forms screw-type connecting clip, and its lower end is the taper that internal diameter reduces successively from top to bottom
Hole 402, it is engaged with the other end of double end bushing 2, multiple grooves is offered vertically in the outer wall of connecting clip 4,.
In the present embodiment, the angular range of the tapered slope of the double end bushing 2 is 3 °~10 °.The double end bushing
