Description
Technical field
The utility model belongs to synchronizer technical field, specifically, in particular to a kind of total tapering inspection of low gear cone hub
Tool.
Background technique
Currently, synchronizer is the critical component of mechanical gear transmission speed variator, synchronizer shift has light and flexible, punching
The advantages that small is hit, the power performance and the economy performance for improving automobile is conducive to.Low gear cone hub assembly is the core in synchronizer
Part, it plays shift, transmitting torque in synchronizer.
The conical surface is formed on low gear cone hub.The taper accuracy of the conical surface is an important behaviour of low gear cone hub quality.Cause
This will detect the taper of product after having produced, and the mode of tapered instrument and worker's manual inspection, in the prior art
Expensive, troublesome in poeration or accuracy is not high, does not have good detection effect.
Utility model content
In view of the defect of the poor universality of the prior art, the technical problem to be solved by the utility model is to provide one kind
Low gear bores the total tapering cubing of hub.
Technical solutions of the utility model are as follows: a kind of low gear bores the total tapering cubing of hub, including bottom plate, the bottom plate it is upper
Surface is provided with the positioning column for being used to support workpiece；It further include the ring gauge having for directly detecting the workpiece conical surface, the ring gauge
Inner wall is up-narrow and down-wide normal cone, is provided on the ring gauge and parallel with ring gauge axis is used to plug dial gauge table bar
Jack, and the jack is close to the normal cone；Ring gauge plugs table bar equipped with dial gauge by the jack, and dial gauge passes through
Screw is pressed closer to fix against table bar and the ring gauge.
Using above technical scheme, as the support of workpiece and the setting main body of other component, positioning column is used to pair bottom plate
Workpiece is felt relieved, and ring gauge cooperates the conical surface of workpiece by normal cone, on this basis again by dial gauge and
Reading confirms the base position of practical measured workpiece taper.The setting of ring gauge normal cone is come with complete standard workpiece, i.e.,
Normal cone is adapted to completely with the conical surface of standard workpiece.Before actually detected, need to carry out calibration, school to dial gauge with proof-reading block
Ideal value to block to embody ring gauge conical surface base position to cone hub end face, then measurement is compared by this cubing, it obtains
The difference of actual value and ideal value.
Further, for the ease of taking and moving ring gauge, the upper surface of the ring gauge is provided with cover board, the cover board it is upper
Surface is provided with connector sleeve.
Further, in order to which the workpiece detected to needs positions, and it is convenient for subsequent processing, the upper surface of the bottom plate
It is provided with the positioning pin of protrusion.
Further, it smoothly positions and supports to guarantee, the quantity of the positioning pin is three.
Further, in order to guarantee to fit closely cooperation with dial gauge, not shake and then influence to measure, the percentage
C-shaped opening set is provided in table hole, the screw that presses closer is resisted against c-shaped opening set outer wall.
The utility model has the advantages that the utility model is novel, design is rationally and convenient for operation, the utility model directly bores low gear
Hub carries out taper detection, quantifies taper situation with the reading of dial gauge, easy to operate and smart relative to existing processing mode
Really, also low in cost, the accuracy of detection and efficiency can improve.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
A kind of low gear as shown in Figure 1 bores the total tapering cubing of hub, has bottom plate 1, the upper surface of bottom plate 1, which is provided with, to be used for
The positioning column 2 of workpiece is supported, the upper surface of bottom plate 1 is provided with the positioning pin 7 of protrusion, and the quantity of positioning pin 7 is three.Further include
Have a ring gauge 3 for directly detecting the workpiece conical surface, the inner wall of ring gauge 3 is up-narrow and down-wide normal cone, be provided on ring gauge 3 with
The parallel jack 3a for being used to plug dial gauge table bar of 3 axis of ring gauge, and jack 3a is close to normal cone；Ring gauge 3 is by inserting
Hole 3a, which is plugged, sets dial gauge 4, and dial gauge 4 is fixed by pressing closer screw and ring gauge 3.C is provided in specifically dial gauge hole 3a
Shape opening sleeve 8, c-shaped opening set 8 are coated on table bar periphery, press closer screw and are resisted against c-shaped opening 8 outer walls of set.The upper surface of ring gauge 3
It is provided with cover board 5, the upper surface of cover board 5 is provided with connector sleeve 6.
In the specific use process, first that bottom plate 1 is fixed on the table, it is then that the workpiece for needing to detect is accurately right
It is placed on station to position, guarantees the upper end top to position reasonable on workpiece of positioning column 2 and positioning pin 7.After placing workpiece,
Ring gauge 3 is placed on workpiece from top to bottom, guarantees that the conical surface of the two is normally bonded, then, reads the instruction on dial gauge 4
Numerical value, and convert with reading of standard, to obtain the data result of taper detection.Calibration is carried out by calibrated bolck before detection
When, dial plate is rotated, in the case of being " zero " for the reading value adjustment of dial gauge 4, when reading is positive value when detection, indicates part cone
Face base position is less than normal to detection faces size, conversely, less than normal.
The preferred embodiments of the present invention have been described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality according to the design of the utility model on the basis of existing technology in domain
Available technical solution is tested, it all should be within the scope of protection determined by the claims.
