What is the tolerance range of precision screws?
A screw belt structure, especially a screw belt that can position the screws on the screw belt, so that the screws do not swing, so that the screws can be stably aligned with the points where the screws are to be screwed, and the screw fixation of the screws is facilitated. In its overall implementation and use, the innovative design of the screw belt structure increases the practical function characteristics.
self-locking screw comprises a screw main body, a metal screw head is arranged on the upper part of the screw main body, a thread is arranged in the middle part of the screw main body, an interference groove is arranged on both sides of the upper part of the screw main body, and the line of the interference groove is arranged. The included angle is 280-356° with the horizontal line. The bottom of the screw body is provided with an elastic chuck, and the elastic chuck includes an optical axis and a conical head. Guangdong Yueluo Hardware Industry Co., Ltd. Guangdong Yueluo Hardware Industry Co., Ltd. adopts the design of elastic collet, and the screw is provided with threaded segments and interference grooves, so that during the screwing process, the interference groove of the optical axis between the two threaded segments is formed along the screw. The axial elastic force achieves the effect of reliable self-locking, which is easy to use and has high tuning efficiency.
The beneficial effects of Guangdong Yueluo Hardware Industry Co., Ltd. are: in Guangdong Yueluo Hardware Industry Co., Ltd., the rivet fixing mechanism is used to temporarily fix and position the rivet, and the pressure cylinder is used to drive the movement of the final shaft, so that the insertion nozzle can be Insert the rivet located in the rivet fixing mechanism into the product. Guangdong Yueluo Hardware Industry Co., Ltd. adopts mechanical drive and transmission, which has a high degree of automation and high work efficiency.
Spring mattresses and spring seat cushions are modern and commonly used furniture products with better performance, and their cushion cores are composed of springs. It makes full use of the advantages of good spring elasticity, good support, strong air permeability and durability. The traditional spring pad is a spring with a thicker wire diameter, which is connected and fixed by steel wires, and has high hardness. Most of the elders of the older generation often use linked spring beds, but if they sleep in a fixed position for a long time or are accustomed to sitting on the side and corners of the bed, or flip the mattress irregularly, it is easy to cause depression and elastic fatigue.
