The measurement deflection instrument of a kind of improvement
Technical field
The measurement deflection instrument that the utility model improves, specifically address deflection instrument and can not detect the diameter run-out on the different cylindricals of tested part and end surface error simultaneously, detection efficiency is significantly promoted.
Background technology
Some problem following is mainly there is in the deflection instrument can purchased in existing market when for detecting part:
Structure: deflection instrument has only installed a motion detection pedestal, if the axial workpiece length of detection is shorter or it is more convenient to operate meeting without detection during step, detection efficiency is also higher. If but detected part have multiple step or length longer time, testing process just needs mobility detect pedestal frequently, accelerates way rub and reduce work-ing life and accuracy of detection.
Being not easy to operator under repetitive operation judge intuitively and statistic mixed-state error, the workload adding operator reduces working efficiency.
Practical novel content
The purpose of this utility model is common deflection instrument has been carried out technological improvement, add motion detection pedestal when not destroying original accuracy of detection thus effectively solve the problems referred to above and make it be more suitable for different testing environment, it is to increase working efficiency.
For solving technical problem described in background technology, the utility model by the following technical solutions:
The measurement deflection instrument of a kind of improvement, it comprises guide rail and moves seat, guide rail moves and is provided with dead head A and dead head B on seat, dead head A is provided with top A, and dead head B is provided with top B and bulb handle, it is characterised in that, guide rail moves seat and is provided with detector, described detector is installed on guide rail by mobile base A and moves seat, and described mobile base A is provided with mobile base B and handle, and described mobile base B is provided with guide rail and meter.
Described top A is fixedly installed in dead head A, and top B is movably installed in dead head B, and regulates top B by bulb handle.
Described mobile base B is movably installed in mobile base A, can axially move along guide rail.
Described dead head A, dead head B are movably connected in guide rail and move on seat, can move seat along guide rail and move.
Described mobile base B is connected with meter, the adjustable different angle and direction of meter.
Described guide rail length is less than the length that guide rail moves seat, makes the distance that detection stroke is no more than between dead head.
The principle of work of this practicality is: mobile base B is movably installed on mobile base A and does axial motion along guide rail, the various outer diameter of axial workpiece or disk-like accessory does diameter run-out, radial run-out, face runout error detect, reduce the movement of mobile base A simultaneously, decrease the abrasion that guide rail moves seat, add the work-ing life measuring deflection instrument; The guide rail that mobile base A then moves seat along guide rail axially moves, and movable base A is then carried out fastening by handle, it is possible to detection axis class or disk-like accessory part ovality, thus to ensure accuracy of detection.
This practical useful effect is: improve on original deflection instrument structure basis, add movable base, solve radial direction, face runout error that deflection instrument can not detect the different steps on part simultaneously, make the detection work can more efficient, high quality completes, simultaneously easy to operate, be easy to safeguard, precision good, cost of manufacture is low.

Embodiment
Measurement deflection instrument in order to make the utility model improve can detect the diameter run-out on the different cylindricals of tested part and end surface error simultaneously, is described further.
The inclined pendulum survey meter of a kind of improvement comprises guide rail and moves seat 1, for the dead head A2 and dead head B3 of adjustable range, for locating the top A4 and top B5 of tested part, for loading and unloading the bulb handle 6 of component, the mobile base A8 that can axially move, can axially move mobile base B9 along guide rail 10, for detecting the meter 12 that data export, for the handle 11 of fastening detected activity base A8.
The dead head A2 of described inclined pendulum survey meter, dead head B3 are installed on guide rail and move on seat 1, and can axially move, and top A4 is fixed in dead head A2, and top B5 is arranged in dead head B3, and loads and unloads tested part by bulb handle 6.
The meter 12 of the detector of described inclined pendulum survey meter is movably connected on mobile base B9, and by doing footpath motion on mobile base A8 at mobile base B9.
Described inclined pendulum survey meter, the mobile base B9 of its detector is movably installed on mobile base A8 and does axial motion along guide rail, the guide rail that movable base A8 then moves seat along guide rail axially moves, and movable base A8 is carried out fastening by 11, handle, to ensure accuracy of detection.
Fig. 3 show the working order of the deflection instrument after improvement when detection of complex constructs part. The various outer diameter of tested part can be detected by shown multiple meter 12 respectively.
The measurement deflection instrument that only mode by illustrating describes a kind of improvement above improves on original deflection instrument structure basis, add movable base, solve radial direction, face runout error that deflection instrument can not detect the different steps on part simultaneously, make the detection work can more efficient, high quality completes, simultaneously easy to operate, be easy to safeguard, precision good, cost of manufacture is low.
