Description
Technical field
The utility model is related to detect grip device, belong to detection field of fixtures.
Background technology
With the fast development of automobile industry, gearbox and engine as automobile important component increasingly
Valued by each automobile manufacturing company, gear has reached as important composition component therein, the manufacture of each size
Very high-end level, but wherein the detection of minor dimension is not taken seriously also, such as the detection of end chamfer size, being no lack of has enterprise
Industry is confined to estimate to the detection of the size.
Probe above existing detection device roughness profile degree instrument can only be in X direction with manually moving Y-direction, therefore examine
Accurately point position can not be captured by surveying instrument.
The content of the invention
To overcome above-mentioned the deficiencies in the prior art, the utility model has provided one kind and may be implemented in detection object accurately
The fixture of positioning measurement.
The technical scheme in the invention for solving the technical problem is：
A kind of gear chamfering detects fixture, and the gear chamfering detection fixture includes body, drill holder and lockable mechanism, institute
Body detection faces are stated equipped with the ball head core shaft perpendicular to the detection faces, the ball head core shaft top is smooth spherical surface knot
Structure；The drill holder is coated on the ball head core shaft to position gear under test；The lockable mechanism is used to prevent detection work
Part rotates.
Preferably, the body is a right angle trapezoid block, and the detection faces are diagonally disposed in the body；Its purpose exists
In convenient for detection gear face both sides chamfering without rotary teeth wheel.
Preferably, the lockable mechanism for bolt and is arranged on the pin hole being adapted on body with the bolt；Its purpose
It is, prevents from rotating in detection process middle gear.
It is further preferred that the pin hole axial line is parallel to the body detection faces and the ball head core shaft axial line phase
It hands over.
It is further preferred that the lockable mechanism is arranged at the body upper part；It is it is intended that easy to operate.
Preferably, the drill holder is boss, and the boss is equipped with the endoporus being adapted with the ball head core shaft；Its purpose
It is, simple in structure, accurate positioning is easy to operate.
During use, the body is placed on roughness profile degree instrument, gear under test is coated at the drill holder
On, it is locked with bolt, prevents gear from rocking.During detection, roughness profile degree instrument stylus selects any one at the top of ball head core shaft
A section (X-direction) finds peak a, is found again perpendicular to the cross-wise direction (Y direction) on the basis of this peak a
Another peak A, A point is workpiece calibration benchmark, then moves Y-axis to the position of product requirement, measures the width of chamfered edge,
The similarly chamfering angle size of detection measurement opposite side.
Compared with prior art, a kind of gear chamfering detection fixture of the utility model can be realized accurate in detection object
Positioning measurement.

Top is smooth spherical structure；The drill holder 3 is coated on the ball head core shaft 2 to position gear under test 5；The lock
Locking mechanism rotates for preventing from detecting workpiece.
Preferably, the body 1 is a right angle trapezoid block, and detection faces 11 are diagonally disposed；Lockable mechanism is bolt 4 and sets
The pin hole 12 being adapted on body 1 with the bolt 4；12 axis parallel of pin hole is in the body detection faces 11 and the ball
Head 2 axial line of mandrel intersects；The bolt 4 is placed in 1 top of body；Drill holder 3 is boss, and the boss is equipped with and the bulb
The endoporus that mandrel 2 is adapted.
During use, the body 1 is placed on 6 workbench of roughness profile degree instrument, gear under test 5 is coated at institute
It states on drill holder 3, is locked with bolt 4, prevent gear 5 from rocking.During detection, roughness profile degree instrument stylus 7 is pushed up in ball head core shaft 2
Portion selects any one section (X-direction) to find peak a, again perpendicular to the cross-wise direction on the basis of this peak a
It is workpiece calibration benchmark that (Y direction), which finds another peak A, A point, then moves Y-axis to the position of product requirement, surveys
The width of chamfered edge is measured, similarly the chamfering angle size of detection measurement opposite side.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that：
It can still modify to the technical solution recorded in previous embodiment either to which part or all technical characteristic
Carry out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is not made to depart from the utility model embodiment
Technical solution.
