Detailed Description
Reference herein to an embodiment means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the utility model. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Examples
An instrument for measuring the tension of a machine tool spindle is shown in figure 1 and comprises a spindle cone 1, a rectangular rubber gasket 2, a Y-shaped rubber sealing ring 3, a main body 4, a spindle core 5, a pressure gauge 6, a combined sealing washer 7, an inner hexagonal flat round head screw 8, an inner hexagonal concave end set screw 9, a steel ball 10 and a pull nail 11, wherein the pull nail 11 is fixedly arranged at one end of the spindle cone 1 with a small diameter, the main body 4 is fixedly connected at the other end of the spindle cone 1, the spindle core 5 is fixedly connected in the main body 4, the pressure gauge 6 is fixedly arranged on the spindle core 5, the main body 4 is matched with an inner hexagonal flat round head screw 8, a combined sealing washer 7 is arranged between the inner hexagonal flat round head screw 8 and the main body 4, the spindle cone 1 is matched with a hexagon socket concave end set screw 9, a steel ball 10 is arranged at the lower end of the hexagon socket flat round head screw 9 in a rolling mode, and the steel ball 10 and the spindle cone 1 are arranged in a rolling mode.

Application of the tension meter: in order to avoid the problems that when the main shaft is used for broaching, the tension is insufficient or too large, the parts of the main shaft are easy to damage and the safety of operators is concerned.
Influence caused by abnormal tensile value:
too large: easily cause the damage of the broach mechanism pulling claw and the handle pulling nail
Too small: when the main shaft broach rotates to process, the bolt cannot be tightly grabbed by the inner claw due to insufficient tension, and at the moment, the main shaft with the rotating handle shell is thrown away easily, so that operators are injured easily, and the precision of the main shaft and the metal plate of a machine tool bed are damaged.
Method for converting actual tension value
1kg/cm2＝10kg＝100N
Example (c): 80kg/cm2X10＝800kg＝80KN＝80000N.
Tension meter reading mode:
the inner area of the tension meter is 10.00875cm2When the data of the pressure gauge 6 corresponding to the pointer of the tension meter is multiplied by 10, the correct tension is obtained, and the unit of Newton 9.8 Newton is 1 kg relative to the unit of Newton shown by the electronic tension meter
