Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1：
Reference picture 2, a kind of angle measurement unit, including base 4 for securing part, it is fixedly connected on the base 4
The detection part for going up and there is the characterizing portion of positioning action and be connected on base 4；The characterizing portion includes being fixed on
The first locating piece 1 on the base 4 and the second locating piece 3 being arranged on the base 4；The detection part includes thousand points
Table 6 and the fixture 5 for being arranged on the base 4 and clamping amesdial 6；The front end face of first locating piece 1 and described the
The left side of two locating pieces 3 is vertical, and the front end face of the first locating piece 1, the left side of the second locating piece 3 and the base 4
Top end face be grouped together into perpendicular positioning space；The left side of second locating piece 3 is arranged on the amesdial 6
Gauge head 61 stroke range in.The top end face of the base 4 is on the basis of state shown in Fig. 2, and the top end face is smooth
Plane, the track that eyeglass is run in the perpendicular positioning space is straight line, it is desirable to three faces that the located space is constituted
It is smooth flat, and be mutually perpendicular to two-by-two.When tested eyeglass 2 encounters amesdial 6 and the gauge head 61 of amesdial 6 is turned right crowded
Pressure, until tested eyeglass 2 is connected on the second locating piece 3, reading simultaneously completes detection.Therefore, the front end of first locating piece 1
Face is smooth flat, and the front end face is close to the side of tested eyeglass 2 during measurement；The top end face of the base 4 is smooth flat
Face, the top end face is close to the bottom surface of tested eyeglass 2 during measurement.
Reference picture 3 and Fig. 4, first locating piece 1 are positioned close at the gauge head 61 of the amesdial 6 and positioned at described
The side of amesdial 6；Second locating piece 3 is arranged at the lower section of the amesdial 6.The front end face of first locating piece 1 and survey
The vertical range of first 61 axis is less than the thickness of tested eyeglass 2, the row of the left side of second locating piece 3 in gauge head 61
In the range of journey.Due to gauge head 61 can the side-to-side movement in the bar of amesdial 6, the movable range of gauge head 61 be its detection
Ultimate range, therefore, when tested eyeglass 2 abuts the low order end that gauge head 61 is moved to, at least can touch the second locating piece 3
Left side, could more accurately complete reading and calculating.
Reference picture 2, the fixture 5 is fixedly connected on the base 4, one end adjustable tightness of fixture 5
Be formed with expanding block, two expanding blocks are connected by screw, amesdial 6 is sticked into after fixed block 5, by screw expanding block from
And amesdial 6 is fixed into fastening.So as to which amesdial 6 is fixedly connected on base 4.
The base 4, first locating piece 1, second locating piece 3 are rectangular parallelepiped structure, so can guarantee that institute
The perpendicularity in the perpendicular positioning space stated and attractive in appearance, it is ensured that the angle of measurement is accurate.
Preferably, the axis of the amesdial 6 and its gauge head 61 is vertical with the left side of second locating piece 3.When
The axis of gauge head 61 and amesdial 6 is vertical with the left side of the second locating piece 3, just can more easily calculate tested eyeglass
The perpendicularity of 2 end face.
As shown in Fig. 2 the front end face of first locating piece 1 is the first locating piece 1 and the contact surface of tested eyeglass 2, institute
It is the second locating piece 3 and the contact surface of tested eyeglass 2, i.e., the second locating piece as shown in Figure 2 to state the left side of the second locating piece 3
3 left end face.The directions such as front, back, left, right, up, down of the present utility model are using state shown in Fig. 2 as reference.
The operation principle of the device is：
The first step, to zero.First it is close to the first locating piece 1 with a benchmark eyeglass (i.e. each extraordinary eyeglass of face perpendicularity)
Front end face, benchmark eyeglass shifted to the right to the left side of the second locating piece 3 along the first locating piece 1 onto, now benchmark eyeglass
Right side is connected to the left side of the second locating piece 3, and at this moment amesdial has individual reading, and this reading then is returned into 0.
Second step, measurement.Tested eyeglass 2 is detected using the method same with the first step, now, the meeting of amesdial 6
A reading is shown, the reading of tested eyeglass 2 is directly read by amesdial 6, this reading is the value D shown in Figure 10,
Complete detection.If the right side face out of plumb adjacent thereto of tested eyeglass 2, will form angle as shown in Figure 10, in addition,
By slide measure or other high-acruracy survey instruments, with regard to can measure tested eyeglass 2 front end face transverse direction foremost point with
The vertical range H of gauge head 61.When the axis of gauge head 61 is vertical with the left side of the second locating piece 3, at this time D and H are straight
The length on two sides of angle triangle, can calculate the perpendicularity of the tested surface of tested eyeglass 2 by trigonometric function.Work as measured lens
When the D of piece is zero, illustrate that the tested surface perpendicularity of tested eyeglass 2 is best, it is vertical with adjacent face, if D is much larger than zero, explanation
Perpendicularity is bad, it is necessary to continue processing.The apparatus structure is simple, is easy to operation, detection efficiency is greatly improved.
In addition, when axis and the left side out of plumb of the second locating piece 3 of gauge head 61, in addition it is also necessary to measure gauge head 61
Axis to the front end face of tested eyeglass 2 the vertical range put foremost.That is D, H and their the 3rd connected sides is constituted
Triangle, differ surely form right angle triangle on three sides at this time obtained, and the quilt of tested eyeglass 2 is obtained by calculating
The angle of side and the left side of the second locating piece 3, at this time, error can be larger, and the result that such case is measured is too late
A kind of upper situation.
Embodiment 2：
Reference picture 5 and Fig. 6, the difference with embodiment 1 are：The side of the base 4 is formed with I-shaped guide rail 41,
