The adaptability of the special-shaped spring is very wide, and the special-shaped spring is different from the conventional spring in that the special-shaped spring is of an irregular structure comprising a straight line section, a large number of bending angles and an inclined section.
After the contour spring production was accomplished, it is exactly the detection of contour spring to dispatch from the factory before indispensable one, need detect finished product contour spring plane degree and dimensional accuracy, but be used for detecting the detection device single structure of contour spring in the current actual production, application scope is little, because the contour spring size is longer, often can appear one end in the detection device the inside and other one end is located the detection device outside, need frequent location operation just can detect, lead to finished product detection efficiency low, the qualification rate is relatively poor.
The special-shaped spring produced by the company at present has the length tolerance requirement from a center hole of the special-shaped spring to the front end of the special-shaped spring not higher than 0.2mm, and the product mainly controls the switching of different gears, and the gear shifting mechanism cannot be switched or tightly held when the gear shifting mechanism exceeds the tolerance, so that the mechanism is scrapped.
SUMMERY OF THE UTILITY MODEL
In order to accomplish the accurate measurement to special-shaped spring, the utility model discloses the decision research and development spring detects frock.
The utility model provides a spring detects frock, includes bottom plate, fixed block, left baffle, right baffle, pivot, percentage table, the fixed block is installed in the bottom plate upper surface, and the front end of the upper surface of fixed block is provided with the pivot, and the left and right sides of fixed block is provided with left baffle and right baffle respectively, and the height that highly is higher than the fixed block of left baffle and right baffle, installs the percentage table at the other end that fixed block upper surface and pivot are relative.
Furthermore, the device also comprises a calibration block, and a calibration block center hole matched with the shaft pin is arranged on the calibration block.
Further, a handle is arranged on the bottom plate.
