Description
Technical field
The utility model relates to gear teeth detection field, particularly relates to a kind of gear shaft teeth portion glitch detection fixture.
Background technology
Gear tooth is beated and can be produced dynamical reaction to axle, easily makes axle tired, produces greater impact, increase the wearing and tearing of gear, produce noise when two gears of engagement can be made when tooth runout error is larger to run.Velocity perturbation is comparatively large, and coefficient of speed fluctuation can be made to increase; When coefficient of speed fluctuation exceedes allowable value, the function of machinery can be made to be affected, and operating accuracy reduces, and efficiency declines.The consistance of gear tooth weighs a standard of the rear precision height of axle core gear processing, some application scenario has high requirement to the difference between the gear teeth, error range must be within the specific limits, otherwise the transmission of miscellaneous part can be affected, thus affect serviceable life, and at present gear shaft teeth portion glitch detection mostly is and with hand, part is fixed on rotation dial gauge on V-arrangement substrate and measures, and adds artificial interference factor, makes data test inaccurate.
Utility model content
It is simple, convenient to operation that the purpose of this utility model is to propose a kind of structure, gets rid of the gear shaft teeth portion glitch detection fixture of artificial interference factor.
For reaching this object, the utility model by the following technical solutions:
A kind of gear shaft teeth portion glitch detection fixture, comprising:
V-arrangement substrate, door type frame, described V-arrangement substrate two sides have square groove in order to fixed gate type frame, depression bar is through the through hole in the middle of door type frame upper ledge, and depression bar has spring through the part cover of through hole, and depression bar lower end is fixed with bracing frame, bracing frame is provided with rotating cylindrical briquettes, described cylindrical briquettes is relative with the V-shaped groove position of described V-arrangement substrate, and dial gauge to be located on V-arrangement substrate and to be comprised dial plate and test rod, and the detection head of this test rod is near the V-type groove inclined-plane of V-arrangement substrate.
Particularly, described cylindrical briquettes is roller or bearing.
Further, described depression bar is processed with screw thread at through hole inferior portion.
The beneficial effects of the utility model:
The utility model structure is simple, convenient to operation, can get rid of artificial interference factor and record more accurate numerical value.
Accompanying drawing explanation
Fig. 1 is the structural representation of the gear shaft teeth portion glitch detection fixture that the utility model embodiment provides;
Fig. 2 is the side view of the structure of the gear shaft teeth portion glitch detection fixture that the utility model embodiment provides;
In figure:

Embodiment
The technical solution of the utility model is further illustrated by embodiment below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the gate Ore-controlling Role that the utility model embodiment 1 provides; Fig. 2 is the side view of the structure of the gear shaft teeth portion glitch detection fixture that the utility model embodiment provides.
The utility model comprises V-arrangement substrate 1, door type frame 2, described V-arrangement substrate 1 two sides have square groove in order to fixed gate type frame 2, depression bar 3 is through the through hole in the middle of door type frame 2 upper ledge, depression bar 3 has spring 4 through the part cover of through hole, depression bar 3 lower end is fixed with bracing frame 7, bracing frame 7 is provided with rotating cylindrical briquettes 5, described cylindrical briquettes 5 is relative with the V-shaped groove position of described V-arrangement substrate 1, dial gauge 6 is located on V-arrangement substrate 1, comprise dial plate and test rod, the detection head of this test rod is near the V-type groove inclined-plane of V-arrangement substrate 1.
In present embodiment, the length of depression bar 3 is determined by the height of door type frame 2, and the length of depression bar 3 is consistent to the length of the least significant end of the V-type groove of V-arrangement substrate 1 with the lower end of door type frame 2 through hole, can measure the gear shaft of different-diameter size like this.
Described cylindrical briquettes 5 is roller or bearing, adopts bearing to be cylindrical briquettes 5, in present embodiment in test process, cut can not be caused because of the gear teeth of ballast weight problem to gear shaft, and in test process, during turning gear wheel shaft, gear shaft can uniform rotation.
Described depression bar 3 upper end is processed with screw thread, the internal diameter of the spring 4 in the utility model is identical with the diameter of depression bar 3, adopt interference fit or clearance fit during assembling, the diameter of depression bar 3 allows the error of certain limit, and the screw thread wherein on depression bar 3 can contact with spring 4 upper part.
During use, depression bar 3 is pulled upwardly, depression bar 3 drives bracing frame 7 and cylindrical briquettes 5 to move up, spring 4 is compressed, detected member 8 is put on the V-shaped groove of V-arrangement substrate 1, after unclamping depression bar 3, due to the elastic force of spring 4, depression bar 3 can be made to move downward, after detected member 8 pushed down by depression bar 3, two contact points between V-arrangement substrate 1 liang of inclined-plane and detected member 8 and cylindrical briquettes 5 form a triangle with the contact point of detected member 8, stable for detected member 8 is fixed on V-arrangement substrate 1, rotate detected member 8 and just can measure beating of detected member 8 teeth portion with dial gauge 6.
The utility model structure is simple, convenient to operation, can get rid of artificial interference factor and record more accurate numerical value.
Spring 4 used in the utility model is pressing spring.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not by the restriction of above-mentioned embodiment; what describe in above-mentioned embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall within the scope of claimed the utility model, and claimed scope of the present utility model is defined by appending claims and equivalent thereof.
