Summary of information:We have more than ten years of production experience in the screw industry, the main products are: tripod nuts, extended...

The key connection is a typical mechanical connection, which is usually used to connect the parts on the shaft and to fix them circumferentially and realize torque transmission. Key connection can be divided into flat key connection, semicircular key connection, wedge key connection and tangential key connection, among which flat key connection is widely used in practical engineering because of its simple structure, good alignment and convenient manufacturing. During operation, torque is transmitted through the contact between the sides of the key and the sides of the shaft and hub grooves. In order to ensure the transmission accuracy, the flat key structure generally adopts the transition fit. Due to its structural characteristics and working conditions, it is difficult to use ordinary mechanical tools to lift and pull out during the maintenance process. If forcibly removed, the key and the mating shaft will be destroyed.

It is suitable for plates of various thicknesses, with a minimum thickness of 0.8mm. When using, the tail number Z corresponding to size A must be determined according to the thickness of the plate and the specification of the nut. The user selects samples and orders according to the tail number in the table according to the thickness of the plate; Accurate control, processing according to the tolerance size of 0-+0.075mm, is punching, and the nut should generally be installed from the broken surface of the plate. The installation process is generally achieved through press riveting operations, and must not be impacted and knocked in.

The structure of Guangdong Yueluo Hardware Industry Co., Ltd. is as follows. Figure 1 is a schematic diagram of the structure of the existing pin shaft stop mode of a general excavator. Figure 2 is a schematic structural diagram of the pin shaft stop used by Guangdong Yueluo Hardware Industry Co., Ltd. for applying the bolt of Guangdong Yueluo Hardware Industry Co., Ltd. Fig. 3 is the left side view according to Fig. 2 of the bolt used for pin stop by Guangdong Yueluo Hardware Industry Co., Ltd.

[0017] FIG. 9 is a top view of the circlip of the bolt that Guangdong Yueluo Hardware Industrial Co., Ltd. is used for pin-stopping. In Figures 1 to 9, the latch (1), the retaining sleeve (2), the pin shaft (3), the bayonet (4), the circlip (5), the misaligned through hole (6), and the misaligned end head (7).

Rivets are mostly used for fixed riveting and movable riveting between parts. The rivets used for movable riveting are mostly cylindrical, and there is no size limit for riveted parts, which is easy to cause parts to be squeezed and deformed during riveting. For example, The parts are inserted into the parts for active riveting. When riveting, the riveting force can easily cause the parts to clamp the parts, which in turn causes difficulty in the movement of the parts and the parts, high operating force and noise problems, and the parts are easily damaged.

An automatic circlip device discloses an automatic circlip device capable of realizing automatic assembly of the circlip to improve production efficiency and reduce labor costs. However, there are problems of low degree of automation and low work efficiency.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: one-piece expansion bolts, spring elastics, nut nuts, countersunk head cross recessed bolts and other products, we can provide you with suitable fastening products piece solution.
