Description
Technical field
The utility model is related to a kind of diameter instruments of inspection, more particularly to a kind of outer diameter instruments of inspection of round leaf.
Background technology
Leaf is the critical component of the electric equipment products such as automobile, motorcycle, electric horn.The diameter of leaf is generally
2.00mm-10.00mm, thickness are generally 0.5mm-1.5mm, and leaf diameter is small, and thickness is thin, individually with traditional measurement tool as blocked
Ruler etc. examines its outer diameter to be inconvenient, and measurement can take considerable time one by one and labour, searching one kind can accurately examine tungsten
Piece outer diameter size, and can realize that batch is examined, the method for saving time and labour is current urgent problem.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of while ensureing to examine accuracy
It can realize the round leaf outer diameter upper and lower bound instruments of inspection that batch is examined.
In order to achieve the above object, a kind of round leaf outer diameter upper and lower bound inspection man designed by the utility model
Tool, it includes the outer diameter upper limit instruments of inspection and the outer diameter lower limit instruments of inspection, and the outer diameter upper limit instruments of inspection includes one flat plate,
Proper alignment is equipped with multiple circular through holes, the outer diameter upper limit value of the diameter of the circular through hole and round leaf to be tested on tablet
Unanimously, the circumference of circular through hole extends to form chamfer shape in two planes up and down of tablet to outside through-hole；The outer diameter
The lower limit instruments of inspection is identical as the shape of the outer diameter upper limit instruments of inspection and construction, the difference is that the diameter of its circular through hole with
The outer diameter lower limiting value of circle leaf to be tested is consistent.
It when utility model works, is tested first using the outer diameter lower limit instruments of inspection, by round leaf heap to be tested
It places on tablet, and makes leaf drawout on tablet, shake tablet simultaneously by sieve movement observation leaf of shaking whether from circle
It is fallen in through-hole, it is round on the outer diameter lower limit instruments of inspection can to show that its outer diameter is less than or equal to from the leaf fallen in circular through hole
The diameter of through-hole is less than or equal to the outer diameter lower limiting value of round leaf, judges that its outer diameter is too small for substandard product；Stay in tablet
On leaf its outer diameter meet lower limit standard, then examine whether its outer diameter meets upper limit mark using the outer diameter upper limit instruments of inspection
It is accurate；On the tablet that this batch of leaf heap is similarly placed to the outer diameter upper limit instruments of inspection, and make leaf drawout on tablet, shakes
Whether tablet is fallen from circular through hole by sieve movement observation leaf of shaking simultaneously, the leaf table that can be fallen from circular through hole
Its bright outer diameter is less than or equal to the diameter of circular through hole on the outer diameter upper limit instruments of inspection, that is, is less than or equal to the outer diameter upper limit of round leaf
Value, judges that it meets outer diameter upper limit standard for qualified products, and leaf its outer diameter stayed on tablet crosses greatly substandard product.It is logical
The inspection of round leaf outer diameter upper and lower limit can be carried out by crossing aforesaid operations, be failed by round logical on the outer diameter lower limit instruments of inspection
It crosses, and can be met the requirements by the leaf of outer diameter upper limit instruments of inspection circular through hole, i.e., outer diameter real value is more than outer diameter lower limit
Value, the leaf for being less than or equal to outer diameter upper limit value are qualified products.
In order to easy to operate, increase worker holds the comfort of the instruments of inspection, and the tablet is rectangle.
In order to easy to operate, while the inspection frequency is reduced, improves checkability, the number of circular through hole on each instruments of inspection
Amount is 150-250.
It tests at circular through hole to ensure that leaf can be reached quickly during shaking sieve, is stacking leaf side
The peripheral chamfer angle of circular through hole is 30-40 degree on the tablet of face, and chamfering width is the 1/10-1/5 of circular through hole diameter；Simultaneously
In order to ensure that the leaf by circular through hole can quickly be fallen, the peripheral chamfer angle of circular through hole on the tablet of another side
For 45-60 degree, chamfering width is the 1/15-1/10 of circular through hole diameter；As further preferred, chamfer shape falls for circular arc
Angle.
In order to enhance the supporting point of handheld tool, while leaf is fallen from the surrounding of tablet during the sieve that prevents from shaking, in heap
The tablet surrounding setting baffle of leaf one side is put, the baffle can be extended vertically upwards by the side of tablet and be formed, also may be used
To be the riser being fixedly connected with tablet side.
The utility model is shaken the instruments of inspection of sieve formula by setting, can fast and accurately judge that round leaf outer diameter is big
It is small, while designing two instruments of inspection can by the way that the size of circular through hole to be respectively set to the upper limit value and lower limiting value of outer diameter
With judge respectively leaf outer diameter whether and meanwhile meet bound standard, to filter out qualified round leaf product.Therefore, it
Has the characteristics that simple structure and reasonable design and easy to use.

Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the side, sectional structural schematic diagram of the utility model.
Fig. 3 is the partial enlargement structural representation of circular through hole in Fig. 2.
Specific implementation mode
The utility model will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1-Figure 3, a kind of round leaf outer diameter upper and lower bound instruments of inspection of the present embodiment description, it includes
The outer diameter upper limit instruments of inspection and the outer diameter lower limit instruments of inspection, the outer diameter upper limit instruments of inspection include one piece of rectangular flat 1, tablet
Upper proper alignment is equipped with 150-250 circular through hole 2, the outer diameter upper limit of the diameter of the circular through hole and round leaf to be tested
Value is consistent, and the circumference of circular through hole extends to form chamfer shape 3, chamfering in two planes up and down of tablet to outside through-hole
Shape is circular arc chamfering；The outer diameter lower limit instruments of inspection is identical as the shape of the outer diameter upper limit instruments of inspection and construction, difference
It is that the diameter of its circular through hole is consistent with the round outer diameter lower limiting value of leaf to be tested.
The peripheral chamfer 3-1 angles of circular through hole are 30-40 degree on stacking leaf one side tablet, and chamfering width is circle
The 1/10-1/5 of shape through-hole diameter, the peripheral chamfer 3-2 angles of circular through hole are 45-60 degree, chamfering on the tablet of another side
Width is the 1/15-1/10 of circular through hole diameter；
Stack leaf one side tablet surrounding be arranged baffle 4, the baffle can by tablet side vertically upward
