Manual correction device for coil spring

Abstract

The invention discloses a manual correction device for a coil spring. The device comprises a bottom plate, a rotating device and a correction device, the correction device is arranged on the bottom plate through the rotating device, the rotating device drives the correction device to rotate so as to achieve correction operation on the coil spring, the bottom plate is a rectangular plate, a throughhole allowing the rotating device to be embedded and rotate is formed in the bottom plate, a limiting stop block for limiting the rotating device is arranged on the bottom plate, the rotating devicecomprises a driving gear and a driven gear which are meshed with each other, the driving gear drives the driven gear to rotate under the action of a handle, a disc integrated with the driven gear is arranged on the driven gear, a support for supporting the correction device is arranged on the disc, the driven gear and the disc sleeve a fixing shaft on the bottom plate, and a fixing disc sleeves the fixing shaft. The correction device is arranged on the bottom plate through the rotating device, the correction device is driven by the rotating device to rotate, correction operation on the coil spring is achieved in combination with corresponding scales, and the product quality is improved.

Description

Technical field:[0001]The invention relates to a spring correction device, in particular to a manual correction device for a coil spring.Background technique:[0002]Coil springs are generally used as the power of micro-machines without electric energy, such as the power of mechanical clocks and timekeeping systems; the power of mechanical phonograph record rotation; mechanical music box; automatic piano; winding toys Power and so on.[0003]In the design of the coil spring, determine the size of the minimum drive torque and the size of the maximum torque that can be used; the torque and speed of the final actuator of the drive; and the total time required to drive and other factors to select from the relevant design manual. , Determine the size of the barrel and the size of the gear and the number of modulus teeth at the same time. After testing, make corrections and finally determine the parameters of each part.[0004]In the prior art, after the coil spring is produced, it is directly ...

Problems solved by technology

[0004] In the prior art, after the coil spring is produced, it is packaged directly. Without detection and correction, there are often coil springs with unqualified torque mixed in the finished product, which affects the product quality. Therefore, after the coil spring is manufactured, it is necessary to Correct the torque of the coil spring to ensure the uniform size of the product torque and improve product quality
