High-speed warp knitting machine crankshaft assembly location degree measuring tool and measuring method

Abstract

The invention discloses a high-speed warp knitting machine crankshaft assembly location degree measuring tool and measuring method. The high-speed warp knitting machine crankshaft assembly location degree measuring tool comprises a reference fixing frame, four adjusting slide blocks, a stop screw, four dial indicators and a zero calibration component; the zero calibration component comprises a zero calibration block and two cylindrical pins, and the zero calibration component can perform zero calibration on the dial indicators before the tool is used; the dial indicators are used for obtaininga coordinate value of the axial line of a crankshaft relative to an oil tank and comparing the same with a theoretical correct size to obtain assembly error values of the axial line of the crankshaftin the horizontal direction and the vertical direction; and the high-speed warp knitting machine crankshaft assembly location degree measuring tool disclosed by the invention can be used for conveniently and accurately measuring the assembly location degree of a high-speed warp knitting machine crankshaft relative to the oil tank.

Description

technical field [0001] The invention belongs to the field of crankshaft assembly precision coordinate measurement, in particular to a high-speed warp knitting machine crankshaft assembly position measurement tool and measurement method. Background technique [0002] The warp knitting machine is a machine for producing warp knitted fabrics, which is the basic and important production equipment in the textile industry. The spindle speed of the traditional warp knitting machine is between 400r / min and 700r / min, and the spindle speed of the high-speed warp knitting machine can reach 1800r / min or higher. Compared with the traditional warp knitting machine, the high-speed warp knitting machine has a huge improvement in production efficiency. improvement. In order to achieve a spindle speed of 1800r / min or higher, the high-speed warp knitting machine has high requirements for assembly accuracy, especially the assembly position of the crankshaft axis relative to the oil tank in the...

AI Technical Summary

Problems solved by technology

Because the crankshaft is connected to the main shaft of the motor and the crankshafts are connected to each other in the high-speed warp knitting machine, if the assembly position of the crankshaft axis relative to the oil tank does not meet the assembly accuracy requirements, the crankshaft will be subjected to additional load, increasing the probability of fatigue fracture of the crankshaft, and also Cause the whole machine to vibrate

[0003] In the high-speed warp knitting machine, the crankshaft is installed inside the oil tank, which brings difficulties to the measurement of the assembly accuracy of the crankshaft. At present, there is no effective tooling or inspection tool for measuring the crankshaft inside the oil tank.

Chinese patent application number 201210219341.9 discloses a comprehensive inspection tool for measuring the position of the crankshaft hole. The position of the feature cannot detect the assembly position of the crankshaft relative to other parts, and the mechanism is complicated and the operation is cumbersome

Chinese patent application number 201510848812.6 discloses a measuring device for the center position of each journal of a crankshaft and a measurement and calibration method, which obtains the position information of the center of each crank journal of the crankshaft, but cannot detect the assembly position of the crankshaft axis. The device adopts The laser displacement sensor obtains the position coordinates of the center of each crankshaft journal, and the manufacturing cost is high

At present, there is no tool or device for measuring the assembly position of the crankshaft. How to solve the assembly position measurement of the crankshaft of the high-speed warp knitting machine in a low-cost, simple and effective way has always been a thorny problem.
