A kind of multifunction simple centering table bar

Technical field

This utility model belongs to field of mechanical technique and in particular to a kind of multifunction simple centering table bar.

Background technology

Along with scientific and technological development, the working ability of equipment is more and more stronger, the precision more and more higher of part processing, and this just needs Our machining persons are wanted can accurately to find the benchmark of part to be processed in process, conventional alignment tool is due to office Sex-limited it is impossible to some apertures of centering；Existing table bar alignment tool can only radially adjust substantially, laterally cannot adjust, and conventional looks for Positive table bar is that lever indicator is clipped on main shaft, and gauge outfit cannot adjust to small hole center position it is impossible to reach centering aperture Purpose, therefore, it is necessary to improve.

Utility model content

The technical problem that this utility model solves: provide a kind of multifunction simple centering table bar, using on table bar and pedestal The dynamic cooperation of through hole, makes lever indicator can adjust within the specific limits, and meanwhile, the through hole fluting design of pedestal makes to be fixed on The lever indicator of table boom end can rotate along table rod axis, thus adjusting the angle of lever indicator, improves lever percentage Table stressing conditions, improve centering precision, expand measurement range, can be more than any of lever indicator gauge outfit diameter with centering Hole position.

The technical solution adopted in the utility model: a kind of multifunction simple centering table bar, there is table bar and pedestal, described base It is formed with, outside seat, the through hole moving cooperation with table bar, and table boom end is fixed with the lever indicator being placed in outside pedestal through through hole Connect, described pedestal lower surface is formed with groove that is parallel with through hole and connecting, is provided with the top fixing to table bar outside described pedestal Silk.

Wherein, it is formed with screwed hole outside described pedestal and screwed hole is through in through hole, described jackscrew screws in screwed hole Table masthead is fastened by its end interior.

Further, described table boom end is axially formed with screwed hole, and described table boom end is formed with vertical with screwed hole And the unthreaded hole connecting, the light in the hole of described lever indicator upper end insertion table boom end simultaneously screwed with screwed hole by jackscrew Afterwards lever indicator is fixed on table boom end.

Further, described table bar outer wall and pedestal lateral wall are formed with corresponding graduation mark.

This utility model advantage compared with prior art:

1st, pass through to adjust the relative position of pedestal and table bar, can be with the hole of centering different-diameter size and cylindrical, regulation table The angle of bar and lever indicator can be applied widely with the hole on any datum level of centering；

2nd, the through hole fluting design of pedestal makes the lever indicator being fixed on table boom end can treat the diametric(al) of gaging hole Arbitrarily adjust, substantially increase centering efficiency and precision；

3rd, this structure can be with the special aperture of centering, special endoporus and special cylindrical；

4th, structure includes table bar and pedestal, and structure is simple, easy to use, and dismounting is simple, and processing cost is low.

Specific embodiment

1-3 describes a kind of embodiment of the present utility model below in conjunction with the accompanying drawings.

A kind of multifunction simple centering table bar, has table bar 1 and pedestal 2, is formed with to move with table bar 1 and joins outside described pedestal 2 The through hole 5 closing, and table bar 1 end passed through through hole 5 and be fixedly connected with the lever indicator 6 in the outside that is placed in pedestal 2, table bar 1 can be Accessible rotation on pedestal 2, thus adjusting the anglec of rotation of lever indicator 6 gauge outfit, specifically, described table bar 1 end is axially It is formed with screwed hole 9, described table bar 1 end is formed with unthreaded hole that is vertical with screwed hole 9 and connecting, on described lever indicator 6 The light in the hole of end insertion table bar 1 end simultaneously is passed through, after jackscrew 3 is screwed with screwed hole 9, lever indicator 6 is fixed on table bar 1 End；Described pedestal 2 lower surface is formed with groove 7 that is parallel with through hole 5 and connecting, therefore, is fixed on the lever hundred of table bar 1 end Divide table 6 arbitrarily can adjust in the diametric(al) treating gaging hole, facilitate lever indicator 6 gauge outfit can rest on measured hole diametric Optional position, is provided with the jackscrew 4 fixing to table bar 1 outside described pedestal 2；Specifically, it is formed with screwed hole outside described pedestal 2 8 and screwed hole 8 be through in through hole 5, described jackscrew 4 screws in its end in screwed hole 8 and table bar 1 is held out against fixation, works as lever After dial gauge 6 gauge outfit position adjustments are good, jackscrew 4 is fixing by table bar 1 after tightening；On described table bar 1 outer wall and pedestal 2 lateral wall It is formed with corresponding graduation mark, clamping aligns first to be conducive to table bar 1 and pedestal 2, and in centering special hole, controllable thick stick The anglec of rotation of bar dial gauge 6 gauge outfit；This structure mainly for cannot centering aperture, the excessive cylindrical and endoporus of diameter, or Need to deflect the gaging hole of certain angle and design, this structural alignment, using the cylindrical rotatable feature of table bar 1, makes lever percentage Table 6 can adjust in the range of ± 20 °, according to the demand angle scalable of part, thus reaching centering aperture and unconventional little The purpose in hole, pedestal 2 upper end sandwiches machine tool chief axis, measures good stability, and precision is high, and this structure is simple, easy to make, can be big Big raising centering efficiency and precision.

Above-described embodiment, simply preferred embodiment of the present utility model, not it is used for limiting this utility model practical range, Therefore the equivalence changes that content described in all claim with this utility model is done, all should include in this utility model claim model Within enclosing.
