Abstract
The utility model discloses a tooth top hardness detecting fixture for discal locomotive driving gears. The tooth top hardness detecting fixture comprises two combined cushion blocks used for supporting and fixing the discal locomotive driving gears. Each combined cushion block comprises a cuboid and a cylinder, a lug boss extending along the length direction of the cuboid is arranged on the upper surface of the cuboid and the cylinder is fixed on the lug boss along the axial direction. The tooth top hardness detecting fixture for discal locomotive driving gears can be used for accurately measuring the tooth top hardness of the discal locomotive driving gears on the condition that driving gear entities are not dissected, thereby saving the production cost. Meanwhile, the two combined cushion blocks are cooperatively used so that the detection surfaces of the driving gears are parallel to the horizontal line and the problem that the correctness of the detection results are affected due to the shaking of the driving gears in the tooth top hardness detecting process can be prevented.
Description
Technical field
The utility model belongs to hardness detection technique field, relates in particular to a kind of plate-like class locomotive main moving gear tooth top tooling for measuring hardness.
Background technology
In prior art, plate-like class locomotive main moving gear is after carrying out carburizing and quenching, normal by the hardness detection to quenching sample or gear dissection tooth piece, draws the tooth top hardness of plate-like class locomotive main moving gear.Yet, detect the true tooth top hardness that can not reflect gear in kind fully for the hardness of quenching sample, and detect for the hardness of dissecting the tooth piece, though can accurately reflect the tooth top hardness of gear in kind, need to be dissected gear, greatly increased production cost.Simultaneously, owing to can't keeping detection faces and horizontal direction parallel also can cause result inaccurate.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the purpose of this utility model is to propose a kind of detection frock that can Measurement accuracy plate-like class locomotive main moving gear tooth top hardness.
The purpose of this utility model will be achieved by the following technical programs:
A kind of plate-like class locomotive main moving gear tooth top tooling for measuring hardness, comprise that two for being supported and fixing combined pad plate-like class locomotive main moving gear, described combined pad comprises a rectangular parallelepiped and a right cylinder, the upper surface of described rectangular parallelepiped is provided with the boss that a length direction along described rectangular parallelepiped extends, and described right cylinder is fixed on described boss vertically.
Preferably, described right cylinder is vertically by being fixedly welded on described boss.
Preferably, the xsect of described boss is isosceles trapezoid.
Preferably, the upper surface of described boss is parallel with the lower surface of described rectangular parallelepiped.
Preferably, the roughness of the lower surface of described rectangular parallelepiped is greater than Ra25, increases the lower surface of rectangular parallelepiped while measuring and the stiction between the sclerometer objective table.
Preferably, the length of described rectangular parallelepiped is 140mm, and width is 50mm, is highly 13mm, and the height of described boss is 12mm; Described cylindrical diameter is 30mm, and length is 140mm.
Outstanding effect of the present utility model is: a kind of plate-like class locomotive main moving gear tooth top tooling for measuring hardness of the present utility model, can be in the situation that do not dissect the driving gear material object, the tooth top hardness of Measurement accuracy plate-like class locomotive main moving gear, saved production cost.Simultaneously, by being used in combination of two combined pad, can make the detection faces of driving gear be parallel to surface level, prevent that driving gear from occurring rocking and affecting the correctness of testing result in tooth top hardness testing process.
Following constipation closes the embodiment accompanying drawing, embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.
The accompanying drawing explanation
Fig. 1 is the front elevation of the combined pad of the utility model embodiment;
Fig. 2 is the vertical view of the combined pad of the utility model embodiment;
Fig. 3 is the detection schematic diagram of the utility model embodiment.
Embodiment
A kind of plate-like class locomotive main moving gear tooth top tooling for measuring hardness of the present embodiment, as shown in Fig. 1 ~ Fig. 3, comprise that two for being supported and fixing combined pad plate-like class locomotive main moving gear 1, combined pad comprises rectangular parallelepiped 2 and right cylinder 3, the upper surface of rectangular parallelepiped 2 is provided with the boss 4 extended along the length direction of rectangular parallelepiped 2, the xsect of boss 4 is isosceles trapezoid, and right cylinder 3 is fixedly welded on (in Fig. 1, shaded side is welding portion) on boss 4 vertically.The upper surface of boss 4 is parallel with the lower surface of rectangular parallelepiped 2.The roughness of the lower surface of rectangular parallelepiped 2 is greater than Ra25, the stiction while increasing measurement between the objective table 5 of the lower surface of rectangular parallelepiped 2 and Rockwell hardometer.Wherein: the length of rectangular parallelepiped 2 is 140mm, and width is 50mm, is highly 13mm, and the height of boss 4 is 12mm; The diameter of right cylinder 3 is 30mm, and length is 140mm.
When application the present embodiment is measured, first the lower surface of the rectangular parallelepiped of two combined pad 2 is placed on the objective table 5 of Rockwell hardometer, its right cylinder 3 is stuck in the teeth groove of driving gear 1, distance between two combined pad can be adjusted according to the modulus of driving gear 1, then aim at the gear teeth of driving gears 1 with the pressure head 6 of Rockwell hardometer, but just Measurement accuracy tooth top hardness number.Through contrast test, show that the hardness detected value of the present embodiment is basically identical with the data of dissection hardness detected value in kind, therefore can take this enforcement to replace the tooth top hardness of examining scleroscopic method detection of gear of dissecting in kind.
A kind of plate-like class locomotive main moving gear tooth top tooling for measuring hardness of the present embodiment, can be in the situation that do not dissect the driving gear material object, and the tooth top hardness of Measurement accuracy plate-like class locomotive main moving gear, saved production cost.The each several part structure of combined pad all can adopt cheap carbon steel processing and fabricating, and cost is lower.Simultaneously, by being used in combination of two combined pad, can make the detection faces of driving gear be parallel to surface level, prevent that driving gear from occurring rocking and affecting the correctness of testing result in tooth top hardness testing process.
The utility model is not limited to aforementioned embodiments; those skilled in the art are under the enlightenment of the utility model technical spirit; also may make other changes, but, as long as function and the utility model of its realization are same or similar, all should belong to protection domain of the present utility model.
