Instrument, price is higher, and required cost is larger, and when especially encountering some large-scale or special-shaped class part, detection operability is not strong.Therefore
Under the premise of guaranteeing measurement accuracy and efficiency, do not have also in industry for the detection of the stick spacing dimension of workpiece internal spline at present
Find suitable method.
Summary of the invention
The technical problem to be solved by the utility model is to propose that one kind can directly detect workpiece internal spline stick spacing
It is whether qualified, and detect the internal spline stick spacing detection feeler gauge of economical included length bar.
In order to solve the above technical problems, a kind of internal spline stick spacing detection feeler gauge of the utility model includes handle, feeler gauge
Head, length bar, nut and block, there are two the blocks, is respectively arranged on the two sides of the feeler gauge head, the feeler gauge head and block point
It is not connected with the handle slide fit, the nut is fixedly linked by screw thread set by the left handle end with the handle,
The block, feeler gauge head are fixed on the handle；The feeler gauge head is equipped with a pair of of keyway, and the length bar is respectively placed in institute
It states in keyway, certain interval is maintained between the block and the length bar, a pair of of guiding key teeth is respectively equipped on the block.
A kind of above-mentioned internal spline stick spacing detection feeler gauge, it further includes positioning pin, on the feeler gauge head and the block
It is respectively equipped with corresponding dowel hole, and is limited by the positioning pin.
The both ends of a kind of above-mentioned internal spline stick spacing detection feeler gauge, the length bar have outer oblique angle, the guiding key teeth
The side of the upper nearly feeler gauge head has evagination, which has inner bevel, described outer with length bar both ends institute band
Oblique angle is corresponding.
A kind of above-mentioned internal spline stick spacing detection feeler gauge, the keyway are triangle keyway.
A kind of above-mentioned internal spline stick spacing detection feeler gauge, the angle of the groove angle of the triangle keyway is 60 °~
120°。
The utility model due to using above-mentioned technical pattern, match and process (before i.e. hot by the pin hole of feeler gauge head and two blocks
After feeler gauge head and block are stacked, the pin hole of both simultaneous processings), guarantee the correspondence of the two position；Meanwhile the three of feeler gauge head
Angular keyway, block guiding key teeth processing respectively correspond respective pin hole, and (keyway of feeler gauge head and the guiding key teeth of block are to separate
Processing, the straightness both guaranteed after assembly by centering pin hole), guarantee the straight of key teeth and the feeler gauge head keyway of two blocks
Dimension.Length bar selection is consistent with length bar used in workpiece, is placed in feeler gauge head keyway, forms logical distance over bar size M2 points of detent plug rule
It is not corresponding with workpiece internal spline stick spacing limiting value.Design has certain interval between block and length bar, limits to length bar
While, also it can be made freely to roll and be moved forward and backward, being unlikely to be crushed out of shape influences measurement accuracy.Thus, the utility model
Both accurate, the efficient Detection & Controling to internal spline stick spacing dimension had been realized, and have in turn ensured the economy of detection, benefit
In popularization and application.
Detailed description of the invention
Fig. 1 is the schematic diagram of existing workpiece internal spline stick spacing dimension；
Fig. 2 is the structural schematic diagram of the utility model feeler gauge；
Fig. 3 is the structural schematic diagram of block in the utility model feeler gauge.
Specific embodiment
As shown in Fig. 2, the utility model internal spline stick spacing detection feeler gauge includes handle 1, feeler gauge head 2, length bar 3, spiral shell
Mother 4, block 5 and positioning pin 6.There are two blocks 5, is respectively arranged on the both ends of feeler gauge head 2.Handle 1 and feeler gauge head 2,5 slide fit of block
It is connected, the left end of handle 1 has screw thread, and block 5, feeler gauge head 2 and handle 1 are fixedly linked by nut 4.It is set on feeler gauge head 2
There is a pair of of triangle keyway 7(certain, the shape of keyway 7 is also possible to other shapes, but in contrast serration tooth form calculates
Simply, processing is relatively easy, distance over bar M2 dimensionally stable after assembly, is better than other tooth forms), position is corresponding with tested spline,
Groove angle β is specifically set according to the size of length bar 3, and angular range is at 60 °~120 °.Length bar used in workpiece shown in length bar 3 and Fig. 1
Diameter dimension (φ d) it is identical, be placed in the triangle keyway 7 of feeler gauge head 2, formed distance over bar size M2(lead to detent plug rule difference
It is corresponding with workpiece internal spline stick spacing limiting value).The both ends of length bar 3 have outer bevel angle α, can play certain guiding role.
As shown in figure 3, block 5 is with a pair of of guiding key teeth 8, tooth form and position are consistent with workpiece internal spline, and with workpiece internal spline
At clearance fit.The side for being oriented to nearly feeler gauge head 2 in key teeth 8 has evagination, which has inner bevel α, with length bar 3
Outer bevel angle α is corresponding (considering processing technology, this structure is most simple, effective).Divide in feeler gauge head 2 and each block 5
Not She You corresponding two dowel holes, and limited by positioning pin 6, guarantee the center of guiding key teeth 8 and the center of length bar 3
Unanimously.Certain interval (the size L as shown in I amplifier section in Fig. 2) is maintained between block 5 and length bar 3, enables length bar 3 certainly
By rolling and being moved forward and backward, it is unlikely to be crushed out of shape, while being also unlikely to fall.
The utility model feeler gauge is divided into drift and no-go gage, and drift size M2 corresponds to workpiece internal spline stick spacing dimension
M1min+2 φ d (" M1 " as shown in Figure 1), no-go gage size M2 correspond to workpiece internal spline stick spacing dimension M1max+2 φ d, when use
If drift can be by workpiece internal spline, and no-go gage cannot then illustrate that measured workpiece stick spacing is qualified by workpiece internal spline.
When production, a pair of of triangle keyway 7 on spline mill processing feeler gauge head 2 is first passed through, length bar 3 is then placed in three
In angular keyway 7, then with being limited before and after two blocks 5.Cone is worn at the both ends of length bar 3, with guiding key teeth 8 on block 5
Evagination position has identical bevel angle α (respectively as shown in I amplifier section in Fig. 2 and Fig. 3), and maintains one both after assembly
Fixed gap enables length bar 3 freely to roll and be moved forward and backward while guaranteeing that length bar 3 will not drop out, be unlikely to be bent,
Positioning causes the variation of M2 size.A pair of of the guiding key teeth 8 and workpiece internal spline tooth form, position consistency of block 5, and match at gap
It closes, preferable guiding role can be played.The utility model feeler gauge can quickly detect any pair of spline of workpiece internal spline as a result,
Slot stick spacing, more accurate compared to existing comprehensive spline plug gauge detection, also more specific aim, qualified or not judgement are directly bright
?.
