Abstract
This utility model belongs to detection instrument, and in particular to thread measurement instrument, including the heart axle coordinated with measuring piece, the heart axle is provided with external screw thread, at least provided with a cell body on the external screw thread, the cell body one end open, the other end is closed, and one end of the cell body opening has elasticity.At least provided with a circular hole, the cell body is three, and is evenly arranged around the axle center of heart axle for one end of the cell body closing；This utility model small volume and less weight, detection efficiency are high.
Description
Technical field
This utility model belongs to detection instrument, and in particular to thread measurement instrument.
Background technology
When insider measures the perpendicularity of female thread, the angle tolerance of screw thread is converted into into position of related features usually, then
Showed with dial gauge, conventional method is by nut sleeve on thread taper mandrel, then by thread taper heart axle clamping
Dial gauge measurement position tolerance is used after leveling on lathe.The thread taper mandrel detection of existing nut measuring for verticality is imitated
The shortcomings of rate is low, weight is big, use is inconvenient,
Utility model content
In order to solve the above-mentioned problems in the prior art, this utility model provides thread measurement instrument.This practicality
New technical problem to be solved is achieved through the following technical solutions：
Thread measurement instrument, including the heart axle coordinated with measuring piece, the heart axle is provided with external screw thread, on the external screw thread
At least provided with a cell body, the cell body one end open, other end closing, one end of the cell body opening have elasticity.
Further, one end of the cell body closing is at least provided with a circular hole.
Further, the circular hole is provided with the cylinder being adapted to circular hole.
Further, the cylinder is straight pin.
Further, the material of the heart axle is 65Mn.
Further, a diameter of φ 4 of the circular hole, the diameter of the cylinder is also φ 4
Further, the cell body is three.
Further, the cell body is evenly arranged around the axle center of heart axle.
This utility model small volume and less weight, detection efficiency are high.
This utility model is described in further details below with reference to drawings and Examples.
Description of the drawings
Fig. 1 is the front view of thread measurement instrument.
Fig. 2 is the side view of thread measurement instrument.
Fig. 3 is the partial enlarged drawing of thread measurement instrument cell body.
Specific embodiment
Technological means and effect that predetermined purpose is taken is reached for this utility model is expanded on further, below in conjunction with accompanying drawing
And embodiment is to specific embodiment of the present utility model, architectural feature and its effect, describe in detail as follows.
Embodiment 1：
Thread measurement instrument, including the heart axle 100 coordinated with measuring piece, heart axle 100 is provided with external screw thread 110, described outer
At least provided with a cell body 111 on screw thread 110, the threaded portion of cell body 111 is outwards ejected, 111 one end open of cell body, the other end
Closing, one end of the opening of cell body 111 have elasticity；Cell body 111 closing one end at least provided with a circular hole 112, on circular hole 112
It is provided with the cylinder being adapted to the circular hole 112, the preferred straight pin of cylinder.The material of heart axle 100 is 65Mn, through the 42- that quenches
The heat treatment method of 47HRC, makes heart axle 100 have elasticity well.
Embodiment 2：
Part unlike the embodiments above is：Cell body 111 is three, axle center uniform cloth of the cell body 111 around heart axle 100
Put, while the threaded outer wall of cell body 111 is outwards ejected.A diameter of φ 4mm of circular hole 112, correspondingly, the diameter of cylinder is also
φ4mm。
When cubing is with screw-internal thread fit, the screw thread of ejection will be cubing and female thread stuck, makes not exist between the two and matches somebody with somebody
Gap is closed, certainty of measurement is improve, it is contemplated that the screw thread of cell body part can fail in life-time service, therefore is provided with the position
Circular hole 112, is inserted into straight pin in the circular hole 112 of root, increased the elasticity of screw thread, extend the service life of cubing.
The using method of the cubing is：It is engaged with female nut with externally threaded heart axle, then by cubing two
With the top fixation of deflection instrument or by cubing clamping on lathe, the part of trough of belt is clamped with scroll chuck, and another part is used at end
Top fixation, then dial gauge is placed on the nut surface for needing measurement, rotates arrangement for measuring verticality to measure hanging down for nut surface
It is straight to spend.
Above content is with reference to specific preferred implementation further detailed description of the utility model, it is impossible to
Identification is of the present utility model to be embodied as being confined to these explanations.For the ordinary skill of this utility model art
For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should be all regarded
To belong to protection domain of the present utility model.
