Problems solved by technology
In the process of device assembly in the prior art, there are two biggest problems: a. The torsion spring is too small, and there is almost no extra space to support the torsion spring; b. The shaft cannot be pressed into the shaft concentrically, which may easily lead to crushing of the product; the product requires high precision, and the available space for positioning and limiting is small, and the large end of the shaft is an interference fit, making it difficult to press in and position accurately

The invention relates to a step shaft and torsional spring adaptive-assembling device. A product base and a product keycap are placed in a positioning carrier of the step shaft and torsional spring adaptive-assembling device. A torsional spring rough-positioning block is arranged on the product base. A sliding groove is formed in the positioning carrier. A sliding block is mounted in the sliding groove. A torsional spring positioning guide rod is mounted on the sliding block. A product rotary shaft guide assembly is mounted on the positioning carrier and comprises a rotary shaft guide groove fixedly formed in the positioning carrier, a rotary shaft guide block mounted on the left side of the rotary shaft guide groove through a hinge pin and a correction elastic piece mounted between the rotary shaft guide groove and the rotary shaft guide block. A correction hole used for correcting the concentricity of a product rotary shaft is formed in the correction elastic piece. The step shaft and torsional spring adaptive-assembling device further comprises a motor module used for slowly pressing the product rotary shaft into the product base and the product keycap and located at a connection position. A push rod is mounted on the motor module. A pressure sensor is mounted between the push rod and the motor module. By adoption of the step shaft and torsional spring adaptive-assembling device, the product base, the product keycap, the product torsional spring and the product rotary shaft can be assembled together.
Description
[0001] Technical field: [0002] The invention relates to the field of jig equipment, and more specifically relates to an adaptive assembly step shaft and a torsion spring device. [0003] Background technique: [0004] In the jig device, sometimes it is necessary to assemble the product base, product keycap, product torsion spring and product rotating shaft together, and the total length of the product rotating shaft is 15.4mm, and the size of the big end is small, only 1.9mm. In the process of device assembly in the prior art, there are two biggest problems: a. The torsion spring is too small, and there is almost no extra space to support the torsion spring; b. Unable to concentrically press into the rotating shaft, which will easily lead to crushing of the product; the product requires high precision, and the available space for positioning and limiting is small, and the large end of the rotating shaft is an interference fit, which is difficult to press in and position accur...
