Threaded connection is a widely used detachable fixed connection, has the advantages of simple structure, reliable connection, convenient assembly and disassembly.

The traditional thread measuring method is contact or the universal tool microscope to measure artificial using thread gauges, heavy workload, work efficiency regulations is low, the measuring result is easily affected by human impact. The contact type measurement, thread gauge is easy to wear, thus affecting the measurement accuracy, the cost is also high replacement gauge. In addition, artificial difficult to complete the inspection work in some occasions. Therefore, need thread detection equipment to solve the bottleneck problem of automatic thread detection, in order to improve the efficiency of enterprises fasteners.

Type selection of threaded fasteners

 

Bolt connection
Used to connect two thinner parts. A through hole is arranged on the connecting piece. The gap between the rod and the hole of the common bolt is low, the structure is simple, the assembly and disassembly is convenient, and the application is wide. Hinge Kong Luoshuan (GB/T 27) hole and screw often used in transition, such as H7/m6, H7/n6. The connection can accurately fix the relative position of the connecting piece.

 

Double headed bolt connection

Used to be one of the more thick, should not be used to connect with bolts, thicker joints are less strength, and often need to be removed. In the thick part of the processing out of the hole, thin parts on the processing of light holes, bolts screw into the screw Kong Zhong, with a nut pressed thin parts. When removing, just unscrew the nut and do not have to remove the head bolt. Can avoid the damage to the threaded hole on the connecting piece.

 

Screw connection

Bolts (or screws) screw directly into the threaded hole of the connecting piece, without the nut. The structure is simpler and more compact than the double headed bolt. For the two to be connected in a thick, but do not need to always be removed, so as to avoid damage to the threaded hole

 

Locking screw connection

By twisting the end of the threaded hole in the part to resist the surface of the other part or the concave pit on the other part, the relative position of the two parts is fixed. This connection mode is simple in structure, and some can change the position of the part in the circumferential direction or the axial direction in order to adjust the fixing of the switch knob of the electric appliance.

 

Head screw

Used for occasions where the strength is not high and the thread diameter is less than 10mm. The screw head or the local sink is connected with the connecting piece, and the structure is used for the occasions that require the outer surface to be smooth, such as the instrument panel.

 

Self tapping screws

Occasions for low connection strength requirements. But in general should be prepared in advance to the bottom. If the use of self drilling screws with a bit part, you do not need to pre bottom for non-ferrous metal, wood, etc.

 

Wood screw connection

Generally used for connecting wooden structure. The wooden pieces depending on the material hardness and wood screw length, can be prefabricated or make a certain size, prefabricated hole depth

 

Self tapping locking screws

The thread is a curved triangular interface, and the screw is hardened by the surface, and can be screwed into the preformed hole of the metal material. The formation of internal thread cut extrusion system improve the strength of more than 30%. Small tensile screws for 800MPa. Self tapping locking screws have low tightening torque, high locking performance, has been in extensive use of household appliances, electrical and automotive industry

 

Fastener - assembly connection

The washer and the outer screw thread fastener are assembled by the standard professional factory. Our country in 1988 issued a 23 fastener assembly production standards. This connection is convenient, time-saving, safe and reliable, is used to closely connected by fastening elements of the occasion, such as terminal cabinet
