Problems solved by technology
[0002] At present, there are micrometers and inner diameter dial gauges for measuring the inner diameter of the cylinder liner, pneumatic measuring instruments and ultrasonic equipment, etc. The micrometer and the inner diameter dial indicator are used together. The measurement is cumbersome, the accuracy is not high, and the level of manual operation is high. , Ultrasonic measurement requires special equipment, dedicated operators and measuring tubes, and the measurement cost is relatively high. Most of the sleeve inner diameter measuring heads have no positioning and guiding functions, so it is very easy for the measuring head to collide with the workpiece and wear during use. In addition, it is difficult for the measuring head to find the center of the cylinder liner under the control of the human hand during the measurement process. The measurement technology is extremely demanding

Embodiment 1
[0017] Operation steps for measuring cylinder liner roundness error: When using, first loosen the upper and lower lock nuts 4, screw up the lower lock nut 4, then lock the upper nut 8, and adjust the position of the positioning sleeve 8 After positioning, the positioning claw 5 can adjust the screw 6 according to the needs, so that the positioning claw has the best positioning angle, the balance must be adjusted on both sides, and then the air pipe of the pneumatic measuring instrument is connected to the inner diameter measuring head, so that the inner diameter measuring head and the pneumatic quantity Connect the instrument, and use the upper and lower limit calibration column of the pneumatic measuring instrument to check the measurement range and accuracy of the inner diameter measuring head; Connect, open the air source valve, let the cylinder rod 10 rise to a position 2cm away from the bottom of the cylinder liner 11, turn off the air source for measurement, record the va...

A cylinder sleeve inner diameter measuring head comprises a measuring head body, an air hole, a measuring rod, a lower locking nut, a location claw, an adjusting screw, an upper locking nut, a location sleeve, a location claw clamping groove, a cylinder rod, a cylinder sleeve, a ruler, a cylinder tube, a cylinder sleeve pad, a cylinder base and an air connection hole. The measuring head is characterized in that the bottom of the measuring head body is arranged to be reversed-conical-shaped, the location claw can automatically find the center of the cylinder sleeve and can measure the same position of cylinder sleeves of the same batch, the cylinder rod can move vertically under the air pressure, the value of any position of the cylinder can be measured, the upper locking nut and the lower locking nut can fix the location sleeve, and the position of the location sleeve can be adjusted conveniently. The measuring head has the advantage of increasing location devices and guide devices on the basis of the cylinder sleeve inner diameter measuring head, the measuring speed and the measuring accuracy are improved, and the abrasion and the collision of the measuring head body can be effectively prevented.
