Mr. Morse taper, there are 0, 1, 2, 3, 4, 5, 6*** seven numbers, taper value has a certain degree of variation, the nominal diameter of each type of size, respectively, 9.045, 12.065, 17.78, 23.825, 31.267, 44.399, 63.348. Mainly used for a variety of cutting tools (such as drills, milling cutters) a variety of toolholders and machine tool spindle hole taper. .
The relationship between taper C and cone angle α is: C=2Xtg(α/2)
Taper plug gauges are mainly used to check the product's large diameter, taper and contact rate, belonging to the special comprehensive inspection tool. Taper plug gauge can be divided into two kinds of size plug gauge and color coated plug gauge. Because of the coloring taper plug gauge design and testing are relatively simple, so in the workpiece measurement has been commonly used.
Taper is the ratio of the diameter of the base of the cone to the height of the cone, or in the case of a circular table, the ratio of the difference between the diameters of the upper and lower two base circles to the height of the cone. Taper plug gauge is mainly used to check the product's large diameter, taper and contact rate, belongs to the special comprehensive inspection tool. Taper plug gauge can be divided into size plug gauge and coloring plug gauge two kinds. Because of the coloring taper plug gauge design and testing are relatively simple, so in the workpiece measurement has been commonly used.
In order to make the connection and dismantling of the wire fasteners between the drilling tools easy, the drilling tool wire fasteners are all in the shape of a cone. The slope of the fine buckle cone is equal to 1/32, this slope is equivalent to the angle between the straight line parallel to the axis of the cone and the axis of the tube, the angle is equal to one-half of the angle at the top of the cone, and its value is 1°47′24″.
So, generally are two times the slope of 1/16 as the full taper of the wire buckle.
Expanded information:
The Morse taper is also divided into long and short taper, the long taper is used for the spindle hole of the main machine tool, the short taper is used for the machine tool accessories and machine tool connection hole. Connection holes, Mohs short taper has B10, B12, B16, B18, B22, B24 six models.
They are based on the Mohs long cone 1, 2, 3 shortened from, for example, B10 and B12 is the Mohs long cone 1 size of the two ends, general machine tool accessories according to the size and the required transmission torque to select the use of short cone, such as commonly used drilling collets 1-13 mm are usually used in the B16 short cone hole.
In the same taper within a certain range, the workpiece can be freely disassembled, and at the same time in the work will not affect the use of the effect, such as drilling taper shank drills, if the use of the need to dismantle the drill bit grinding, disassembled and reassembled will not affect the center of the drill bit position.
Taper pins 1:50 used to fix parts, transfer torque and axial force. 1:50 positioning taper pins, tool taper, etc. are for the purpose of dismantling the fixed they are convenient, to prevent the parts connected to the wrong position. It is an international standard for taper, used for static fitting to precisely locate. Because the taper is very small, the use of the principle of friction, can transfer a certain amount of torque, and because it is a taper fit, so it can be easily disassembled.
In a certain range of the same taper, the workpiece can be freely disassembled and assembled, and at the same time in the work will not affect the use of the effect, such as drilling taper shank drills, if the use of the need to disassemble the drill bit grinding, disassembled and reassembled will not affect the center of the drill bit position.
