The driving motor 31 drives the rotary indexer 32, and the rotary indexer 32 drives the spring to be tested 100 to perform an eight-position rotation movement.
[0035] During detection, the spring 100 to be detected is vertically installed on the material clamping platform 30. The material clamping platform 30 drives the spring 100 to be detected to rotate intermittently for position adjustment. Each time the position adjustment is completed, the first position adjustment device 50 adjusts the position of the first detection component 70 on the X, Y, and Z axes, and the second position adjustment device 60 adjusts the position of the second detection component 80 on the X, Y, and Z axes. During the position adjustment process, the first detection component 70 acquires an image of the side of the spring 100 through the first lens module 71 and transmits it back to the host computer. The settings of the first lens light source 72 and the surface light source 40 can provide the clarity of the image. The second detection component 80 acquires the data and image of the spring 100 from above the spring 100 to be detected. Among them, the laser displacement sensor 83 of the second detection component 80 can acquire height and profile data, and the second lens module 81 of the second detection component 80 acquires an image of the top of the spring 100. The mapping function module of the host computer fits the shape of the spring 100 being detected based on the data of the first detection component 70 and the second detection component 80, and compares it with the preset data of the spring 100, so as to judge whether the shape of the spring 100 being detected is compliant.
[0036] The beneficial effects of the spring measuring instrument of the present utility model are as follows: By setting the material clamping platform 30, the support frame 20, the first position adjustment device 50, the second position adjustment device 60, the first detection component 70, and the second detection component 80, the material clamping platform 30 drives the spring 100 to be detected to rotate intermittently for position adjustment. The first position adjustment device 50 adjusts the position of the first detection component 70 on the X, Y, and Z axes, and the second position adjustment device 60 adjusts the position of the second detection component 80 on the X, Y, and Z axes. During the position adjustment process, the first detection component 70 and the second detection component 80 acquire the data of the spring 100 and perform detection and judgment. The spring measuring instrument of the present utility model is a non-contact programmed automatic measurement, which can completely avoid the problems of large deviations caused by manual techniques and proficiency levels, as well as the correlation of detection data. At the same time, it can also quickly and intuitively display the detection data through a computer monitor to achieve fast, efficient, and consistent measurement points each time. In addition, it has the data feedback and statistical function of SPC (Statistical Process Control), and the fully automatic spring measuring instrument provides a basis for the optimization and improvement of the previous production processes.
