Problems solved by technology
The existing method of measuring the number of spring coils is to count the number of coils one by one by the inspectors. In the case of a large number of spring coils and a large batch, this measurement method causes problems such as large measurement errors, low efficiency, and high labor intensity.

Embodiment Construction
[0014] A spring coil number measuring device such as figure 1 Shown: including the frame 1 and the permanent magnet low-speed synchronous motor 3 fixedly installed on the frame 1 through the motor mounting frame 2, the power output end of the permanent magnet low-speed synchronous motor 3 is connected through the coaxial transmission of the coupling 5 and is in use When passing through the wearing shaft 9 in the corresponding spring 17 to be tested, the coupling 5 is also provided with a spring clamping structure for coaxial transmission connection with the corresponding spring 17 to be tested and to transmit torque to the corresponding spring 17 to be tested (not shown in the figure), the permanent magnet low-speed synchronous motor 3 can drive the wearing shaft 9 and the corresponding spring 17 to be tested to rotate synchronously through the shaft coupling 5 . The axial direction of the threading shaft 9 extends in line with the length direction of the frame 1 , and the end...

The invention relates to a device for measuring spring coil numbers. The device comprises a rack, wherein a penetrating shaft is assembled on the rack in a detachable rotation manner; the penetrating shaft is driven by a corresponding power source, penetrates through a spring to be measured and is rotated synchronously with the spring to be measured when being used; a detecting mechanism which is used for detecting the number of coils through which the penetrating shaft penetrates is arranged on the rack beside the penetrating shaft; a guide sliding track of which a guide direction is parallel to a shaft direction of the penetrating shaft is also arranged on the rack beside the penetrating shaft; a sliding bracket is assembled on the guide sliding track in a guide sliding manner; a cursor head which extends towards the direction of the penetrating shaft is arranged on the sliding bracket; one end of the cursor head is fixedly connected with the sliding bracket; and a matching part which is matched with a spring body of the spring to be measured while the spring to be measured is rotated so as to form screw nuts and a lead screw transmission mechanism with the spring to be measured is arranged at the other end of the cursor head. The invention provides a device for measuring the spring coil numbers; working intensity of workers is reduced, and at the same time, measuring efficiency of the spring coil numbers is improved.
Description
technical field [0001] The invention relates to a spring parameter detection device, in particular to a spring coil number measurement device. Background technique [0002] Springs are widely used components in the mechanical field. In industrial manufacturing, it is often required that mass-produced springs have the same characteristics, which requires that the springs should first have the same parameters. The parameters of a spring can be characterized by the number of turns, free length, diameter and pitch. After the spring is manufactured or before use, these parameters need to be measured, the most important of which is the number of coils. [0003] Especially in some special and critical fields (such as aerospace) applications, the requirements for dimensional accuracy such as the number of spring coils are more stringent. The existing method of measuring the number of spring coils is to count coils one by one by inspectors. In the case of a large number of coils an...
