Embodiment Construction
[0037] The present invention will be further described below in conjunction with the accompanying drawings of the description.
[0038] Such as Figure 1-2 As shown, the detection device for the number of coils of the coil spring of the present invention includes:
[0039] base01;
[0040] The lower chassis 02 for carrying the lower end of the tested helical spring 07 is located on the base 01 and is provided with a positioning structure for positioning the lower end 71 of the tested helical spring;
[0041] The lower end of the vertically arranged support rod 03 is fixed at the center of the lower chassis, that is, fixed relative to the center of the lower chassis, so that the two maintain a relatively stable positional relationship;
[0042] The upper chassis 04 is used to be sleeved on the support rod 03 and press the upper end of the coil spring to be tested;
[0043] Dial 05, which is non-rotatably sleeved on the support rod 03 and positioned on the upper side of the u...

The invention discloses a detection device for the number of coils of a spiral spring. The existing detection device for the number of coils of a spring is limited in use and troublesome to operate. The invention comprises a base; Positioning structure; vertically arranged support rod; upper chassis for being sleeved on the support rod and pressing the upper end of the coil spring to be tested; dial, which is non-rotatably sleeved on the support rod and located on the upper side of the upper chassis, its There is a scale on the upper side, and the scale corresponding to the positioning structure of the lower chassis is set as the initial scale; the pointer assembly, which is rotatably sleeved on the support rod, includes a reading pointer for reading the scale on the upper side of the dial and a reading pointer located on the upper side of the dial. The lower side of the upper chassis is used to locate the positioning pointer on the upper end of the coil spring under test. The detection device simulates the actual assembly state of the coil spring for detection, is not limited by conditions, is simple and convenient to operate, and can intuitively and accurately read the non-integer number of coils of the coil spring from the dial.
Description
technical field [0001] The invention belongs to a spring detection device, in particular to a detection device for the coil number of a helical spring. Background technique [0002] As a technical indicator of the coil spring, the number of turns of the coil spring is indispensable in actual production and testing. At present, the inspection of the number of spiral spring coils mainly relies on manual visual inspection to identify whether the number of spring coils is qualified, which is too subjective, and it is easy to make mistakes when conducting mass inspections, and cannot guarantee the pass rate of factory springs. Especially the detection of non-integer circles is difficult to realize by manual visual inspection. [0003] The Chinese invention patent application with the application publication number CN104296622A discloses "a spring coil number detection device", which includes screws, base fixing blocks, connecting rods, lock nuts, positioning adjustment rods, mov...
