主刻度板1c的内侧圆弧半径与副刻度板2c的外侧圆弧半径相同且为A,主卡尺钳口1a与连接圆销3圆心的距离与副卡尺钳口2a与连接圆销圆销3的距离相等且为B,A与B的比值为常数K,常数K为本实施例中间隙检测专用卡尺刻度线间距放大倍率;主卡尺1和副卡尺2通过连接圆销3连接成一体,连接圆销3可以是铆钉结构,通过热铆后冷却将主卡尺1和副卡尺2连接成一体,也可设计成其他结构形式,使得主卡尺1和副卡尺2贴合紧密且保证主卡尺1和副卡尺2可绕连接圆销3作无间隙自由回转运动。The inner arc radius of the main scale plate 1c is the same as the outer arc radius of the auxiliary scale plate 2c and is A, the distance between the main caliper jaw 1a and the center of the connecting round pin 3 is the same as that between the auxiliary caliper jaw 2a and the connecting round pin round pin 3 The distance is equal and is B, the ratio of A to B is a constant K, and the constant K is the magnification of the scale line spacing of the special caliper for gap detection in this embodiment; the main caliper 1 and the auxiliary caliper 2 are connected into one body through the connecting round pin 3. The round pin 3 can be a rivet structure, and the main caliper 1 and the auxiliary caliper 2 are connected into one body by cooling after hot riveting, and can also be designed into other structural forms, so that the main caliper 1 and the auxiliary caliper 2 are closely bonded and ensure that the main caliper 1 and the auxiliary caliper The auxiliary caliper 2 can freely rotate around the connecting round pin 3 without clearance.
主卡尺钳口1a与副卡尺钳口2a重合时,指示箭头2d对应主刻度板1c的刻度线为零刻度线,且主卡尺钳口1a与副卡尺钳口2a张开的实际直线距离与指示箭头2d对应主刻度板1c上刻度线的标定值相同;刻度线与主刻度板1c内侧圆弧边线交叉的点为刻度线起始点,零刻度线与主刻度板1c内侧圆弧边线交叉的点为零刻度线起始点,相邻刻度线的标定值差为L,标定值差L可根据预定要求设定。主刻度板上相邻刻度线起始点与零刻度线起始点的直线距离差为标定值差L与常数K的乘积;并且,主刻度板1c上的刻度线由内向外、且由小到大进行标注。When the main caliper jaw 1a coincides with the auxiliary caliper jaw 2a, the scale line of the main scale plate 1c corresponding to the indicator arrow 2d is the zero scale line, and the actual straight-line distance between the main caliper jaw 1a and the auxiliary caliper jaw 2a is the same as the indication Arrow 2d corresponds to the same calibration value of the scale line on the main scale plate 1c; the point where the scale line crosses the inner arc edge line of the main scale plate 1c is the starting point of the scale line, and the point where the zero scale line intersects the inner arc edge line of the main scale plate 1c is the starting point of the zero scale line, and the calibration value difference between adjacent scale lines is L, and the calibration value difference L can be set according to predetermined requirements. The linear distance difference between the starting point of the adjacent scale line on the main scale plate and the starting point of the zero scale line is the product of the calibration value difference L and the constant K; and, the scale line on the main scale plate 1c is from inside to outside, and from small to large Make an annotation.
本实施例中主卡尺钳口与副卡尺钳口的形状相同、且剖面均为圆弧,即主卡尺钳口与所述副卡尺钳口圆弧表面相切重合时,指示箭头对应所述主刻度板的刻度线为零刻度线。当然,主卡尺钳口和副卡尺钳口的剖面也可以直接设计成一个小圆凸点。In this embodiment, the jaws of the main caliper and the jaws of the auxiliary caliper have the same shape, and the cross-sections are all circular arcs. The scale marks on the scale plate are zero scale marks. Certainly, the profile of the main caliper jaw and the auxiliary caliper jaw can also be directly designed as a small round bump.
下面具体阐述刻度线的设定:The following describes the setting of the scale line in detail:
当主卡尺钳口1a和副卡尺钳口2a圆弧表面相切重合时,在主刻度板1c上与副刻度板2c上的指示箭头2d相对应的刻度线,其标定值标定为零;当主卡尺钳口1a与副卡尺钳口2a的实际直线距离为1mm时,与指示箭头2d指示对应的主刻度板1C上的刻度线标定值也为1mm,标定值1mm的刻度线起始点与零刻度线起始点的直线距离则为K×1mm。同理,当主卡尺钳口1a与副卡尺钳口2a的实际直线距离为S时,与指示箭头2d指示对应的主刻度板1C上的刻度线标定值也同样为S,而S刻度线起始点与零刻度线起始点的直线距离则为K×S。由此可知,所有刻度线起始点与零刻度线起始点的直线距离为该刻度线的标定值与常数K的乘积,当相邻两刻度线的标定值差设为0.2mm,则相邻刻度线起始点与零刻度线起始点的直线距离差为则为K×0.2mm。When the arc surface of the main caliper jaw 1a and the auxiliary caliper jaw 2a are tangentially coincident, the calibration value of the scale line corresponding to the indicator arrow 2d on the main scale plate 1c and the auxiliary scale plate 2c is set to zero; when the main caliper When the actual straight-line distance between the jaw 1a and the auxiliary caliper jaw 2a is 1mm, the calibration value of the scale line on the main scale plate 1C corresponding to the indicator arrow 2d is also 1mm, and the starting point of the scale line and the zero scale line of the calibration value 1mm The linear distance from the starting point is K×1mm. Similarly, when the actual linear distance between the main caliper jaw 1a and the auxiliary caliper jaw 2a is S, the calibration value of the scale line on the main scale plate 1C corresponding to the indicator arrow 2d is also S, and the starting point of the S scale line The linear distance from the starting point of the zero scale line is K×S. It can be seen that the straight-line distance between the starting point of all scale lines and the zero scale line starting point is the product of the calibration value of the scale line and the constant K. When the calibration value difference between two adjacent scale lines is set to 0.2mm, the adjacent scale line The linear distance difference between the starting point of the line and the starting point of the zero scale line is K×0.2mm.
结合图4所示,本实施例专用卡尺的使用方法如下:In conjunction with shown in Figure 4, the usage method of the special-purpose caliper of the present embodiment is as follows:
1)将专用卡尺的主卡尺钳口1a和副卡尺钳口2a放入需测量的目标物件4槽口内,然后张开主卡尺钳口1a和副卡尺钳口2a,使主卡尺钳口1a和副卡尺钳口2a分别与目标物件4表面接触,稳定专用卡尺位置;1) Put the main caliper jaw 1a and the auxiliary caliper jaw 2a of the special caliper into the notch 4 of the target object to be measured, and then open the main caliper jaw 1a and the auxiliary caliper jaw 2a so that the main caliper jaw 1a and the auxiliary caliper The jaws 2a are respectively in contact with the surface of the target object 4 to stabilize the position of the special caliper;
2)在主卡尺1的主刻度板1c上,读出与副卡尺2指示箭头2d相对应的刻度线标定值,即完成目标物件4的间隙测量。2) On the main scale plate 1c of the main caliper 1, read the calibration value of the scale line corresponding to the indicating arrow 2d of the auxiliary caliper 2, that is to complete the gap measurement of the target object 4.
