Description
Technical field
The present invention relates to spline spline testing equipment fields, and in particular to a kind of external splines detecting tool.
Background technique
In the prior art, when being often used contourgraph and being measured to the part of spline, generally using bench vice by spline
Step up to fix, then center and horizontal position by manually visualizing adjustment spline, makes the central axis and contourgraph of spline
Central axis be overlapped, keep the end face of spline parallel with the measuring staff of contourgraph, but manually visualize adjustment there are large errors, cause
Measurement accuracy is poor, and low efficiency, at the same spline clamp after adjust again spline center and horizontal position it is very inconvenient, this
Outside, spline is clamped by bench vice, is also easy to cause the scratch of splined surfaces and deformation.
In the prior art, a kind of spline detects fixture, is set in the detection platform of spline detector, including adjustment pedestal
With the adjustable isometry block being disposed thereon, adjusts pedestal and be divided into pedestal and upper and lower level adjusting platform, adjusted in pedestal and lower layer flat
Two middle side parts of platform have been arranged in pairs regulation handle, the top side for being connected to one layer of adjusting platform respectively；Adjust platform
Slider bar and the locating piece cooperation being arranged by adjacent surface position and can Relative slidings；The support platform of the adjustable isometry block
It is threadedly engaged and is connect by height adjustment with block.Its shortcoming is that structure is complicated, is more troublesome to the adjustment of spline, and
And the detection fixture is only applicable to single spline, is not suitable for the spline of various shape, size, poor universality.
Summary of the invention
It is easy to operate the purpose of the present invention is to provide a kind of spline detecting tool, it had not only been able to achieve the positioning of external splines, but also
External splines can be measured, measurement is accurate, and versatility is good.
In order to achieve the above objectives, base case of the invention is as follows：
Spline detecting tool, it is described including workbench, the two independent clamp bodies and jacking block of symmetrical setting

Inclined-plane forms the upside down funnel shape channel that passes through for the jacking block, and two walls of the jacking block are respectively arranged with third inclined-plane and the
Four inclined-planes, the third inclined-plane and with first inclined-plane cooperation offset, the 4th inclined-plane and second inclined-plane cooperation phase
It supports, is provided with the groove being caught in for external splines keyway on the inside of the external clip, one of them described external clip is internally provided with sky
Chamber, the cavity inside are provided with shaft, the tape measure of measurement external splines are wound in the shaft, the tape measure starting point is set
It is equipped with the first magnet, the opening passed through for tape measure is provided on the inner sidewall of the external clip, is coaxially disposed in the shaft with teeth
Wheel offers mounting hole be connected to the cavity on the bottom wall of the groove, be provided in mounting hole one it is extended described in
The convex block of mounting hole, the side of the convex block are provided with the rack gear engaged with the gear, the convex block and the mounting hole
Side wall is provided with and the second magnet that the opening is opposite by the connection of two springs on the inner wall of another external clip, institute
The polarity for stating the first magnet and the second magnet is opposite.
The working principle of base case of the present invention：Two clamp bodies are placed on the table, jacking block are passed through inverted
Funnel-shaped passage is inserted between the internal clip and external clip, the respectively arranged third inclined-plane of two wall of jacking block, the 4th inclined-plane
It offsets respectively with first inclined-plane and the second inclined-plane, so that internal clip and external clip separate and enter for external splines, at this point, will top
Block takes out between external clip and internal clip, and the internal clip and external clip are because tension spring will restore deformation, thus internal clip quilt
Tension spring, which hauls, to be moved to the outside, and external clip is hauled by tension spring toward medial movement, and external clip and internal clip cooperate external splines at this time
It is clamped, so that the keyway of external splines is caught in the groove.
When the keyway of the external splines is caught in groove, the convex block being arranged in the groove mounting hole is by external splines keyway
Wall squeezes, so that convex block overcomes the elastic force of the spring mobile toward cavity inside from mounting hole, the convex block side wall is to cavity
Inside is mobile, so that the gear being meshed with the rack gear of side wall setting rotates, drives and rotates with the coaxial shaft of gear, by tape measure
Expansion pulls starting point mobile toward another external clip, is set by starting point so that the starting point of tape measure is exposed from the opening
The second magnet that the first magnet set and another external clip inner wall are arranged is magnetic attracting and is bonded together, and can pass through reading at this time
Ruler obtains external splines keyway to the diameter between keyway, to realize precise measurement.
The beneficial effect of base case of the present invention：Compared with prior art, it is able to achieve externally using the spline detecting tool
The positioning of spline, and the diameter between the keyway of external splines can be measured, two symmetrical clamp bodies are separately provided, can root
According to the distance between two clamp bodies of various sizes of adjustment, various sizes of external splines preferably can be fixed and measure, it can also root
Different according to the size of external splines, adjustment jacking block is inserted into extent control internal clip and external clip between the external clip and internal clip
Between separated distance, versatility is good.
Preferred embodiment one：As the preferred embodiment of basic scheme, pulley is installed below described two independent clamp bodies,
So that two independent fixture physical efficiencys are slided on the table, to realize that the distance between two separate clamps bodies are adjusted.
Preferred embodiment two：Preferably one preferred embodiment, straight line is provided with for the pulley on the workbench
The sliding rail of sliding, so that two independent fixture physical efficiencys are slided on the sliding rail, so that two independent clamp bodies are always positioned at
On straight line.
