Service HotlineThe opening circlip is widely used in many industrial fields and plays a role in limiting the position of the parts. When in use, as long as the circlip is installed in the circlip groove of the part, the position of other matching parts can be effectively limited, so as to avoid the axial displacement of the matching parts. Since some opening circlips do not have circlip pliers installation holes, circlip pliers cannot be used and can only be installed by hand, which not only cannot effectively ensure the installation quality of the circlip, but also limits the efficiency of installation work.
The diameter, length and quantity of the stud bolts shall meet the requirements, and the type and material of the stud bolts shall be determined by the grade. There are two types of commonly used stud bolts (also known as full-threaded studs). The thread is divided into two types: coarse thread and fine thread. The coarse thread ordinary thread is expressed by M and the nominal diameter, and the fine thread ordinary thread is expressed by M and the nominal diameter × pitch. The fastener standard stipulates that M36 bolts use coarse thread, M36 and above diameters can use fine thread, and the pitch is 3. bm=1d studs are generally used for the connection between two steel connected parts; bm=1.25d and bm=1.5d studs are generally used between cast iron connected parts and steel connected parts The connection between the two; bm=2d double-ended stud is generally used for the connection between the aluminum alloy to be connected and the steel to be connected. The former connector has internal threaded holes, and the latter connector has through holes. The threads at both ends of the equal-length studs need to be matched with nuts and washers, and are used for two connected parts with through holes. One end of the welding stud is welded on the surface of the connected piece, and the other end (threaded end) passes through the connected piece with a through hole, and then the washer is put on, and the nut is screwed on, so that the two connected pieces are connected as a whole.
shaft retaining ring installation tool and an installation method thereof relate to an assembly tool and an installation method thereof, comprising a pressing cylinder and a taper sleeve. The maximum diameter of the tapered end is slightly smaller than the inner diameter of the circular straight hole of the pressing cylinder, and the lower end of the tapered sleeve has a positioning structure matched with the shaft of the shaft retaining ring to be installed. The method includes the following: place the taper sleeve on one end of the shaft where the shaft retaining ring is to be installed and position it well, then place the shaft retaining ring on the tapered end of the taper sleeve, and finally press down the pressure cylinder to make the shaft Use the retaining ring to slide down the conical surface of the taper sleeve to the shaft to be installed with the retaining ring for the shaft, and finally get stuck in the groove of the shaft. Yueluo does not need to open the retaining ring for the shaft, which reduces the operation force and labor intensity. The operation method is simple, the structure is simple and reliable, the cost is low, and it is easy to popularize and use.
Nuts and washers are both small and medium-sized components of the tension reinforcement system, and they are easily lost on the construction site when used separately, which is not conducive to the storage management of turnover materials; 3) During the process of formwork support and removal, they must be installed individually And demolition, thus adding a construction process, affecting the efficiency of construction.
The inch thread is the thread size marked in inch. According to the shape, it is divided into two types: cylindrical and conical; according to the tooth angle, it is divided into two types: 55° and 60°. The 1/4, 1/2, 1/8 marks in the thread refer to the diameter of the thread size in inches. One inch equals 8 cents, 1/4 inch equals 2 cents, and so on.
