Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] see figure 1 , figure 2 and image 3 According to this, the kingpin shaft 1 is provided with a flange 7, a cylindrical shaft section 8, a conical shaft section 9, and a threaded section 10. The end of the flange 7 away from the cylindrical shaft section 8 is provided with a hexagonal head 6 for easy clamping of loading and unloading tools. The threaded section 10 is provided with a pin hole 11 and a cotter pin 5, and also includes a cylindrical pin sleeve 2. The cylindrical pin sleeve 2 has a conical inner hole and is provided with a radial opening groove 13. The conical inner hole of the cylindrical pin sleeve 2 12 fits and fits on the conical shaft section 9 of the main pin shaft 1, the washer 3 and the nut 4 are installed on the threaded section 10 and the cotter pin 5 cooperates with the pin hole 11 to lock.

Abstract

A positioning connection pin includes a main pin shaft (1), a gasket (3) and a nut (4). The main pin shaft (1) includes a flange (7), a cylindrical shaft section (8), a conical shaft section (9) and a threaded section (10) sequentially, and further includes a cylindrical pin bush (2) provided with a conical inner hole (12) and a radial open slot (13), wherein the cylindrical pin bush (2) is matched with the conical shaft section (9) of the main shaft pin (1) in a sleeving manner, and the gasket (3) and the nut (4) are mounted on the threaded section (10). The positioning connection pin is different from the common cylindrical pin and conical pin connection structure, and the conical shaft section (9) of the main shaft pin (1) is matched with the conical inner hole (12) of the main pin shaft (1) for use, thereby greatly facilitating connection, lowering the manufacturing requirements of connected pieces, and improving the assembly efficiency and the reliability.

Description

technical field [0001] The invention relates to a connecting pin, in particular to a positioning connecting pin. Background technique [0002] Generally, the positioning connection pin is realized by cylindrical pin or conical pin. It is difficult to align the pin holes on the two connected parts accurately during assembly. The drilling accuracy of the connected parts is relatively high, the manufacturing cost is high, and the assembly is time-consuming. Operability is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a positioning connection pin with low requirements on the drilling accuracy of the connected parts, convenient disassembly and assembly, multiple disassembly and assembly, high efficiency and good safety. [0004] In order to solve the above technical problems, the present invention provides a positioning connecting pin, which includes a kingpin shaft, a washer and a nut. The pin sleeve, the c...
