Novel high-strength mechanical hardware

Abstract

The invention relates to the technical field of hardware, and discloses novel high-strength mechanical hardware. The novel high-strength mechanical hardware comprises a workpiece, a shaft hole is formed in the center of the upper surface of the workpiece, a through hole is formed in the position, close to the shaft hole, of the upper surface of the workpiece, a main shaft is inserted into the workpiece, the surface of the main shaft is sleeved with an upper connecting piece, and the upper surface of the main shaft is fixedly connected with a spline. According to the novel high-strength mechanical hardware disclosed by the invention, through the arrangement of a nut, a cap ring, a shell, a screw hole and other structures on a fastening device, the shell is clamped to the surface of the nut,rotation of the nut is facilitated, operation of workers is facilitated, one end of the bolt can be in threaded connection with the interior of the screw hole, the possibility that the nut falls offwhen the workpiece is used is reduced, and the bottom of the bolt can be effectively protected, the situation that the bolt is rusted due to the fact that a large amount of oil stains and dust are attached to the surface of the bolt, and consequently, the bolt is inconvenient to disassemble in the later period is avoided, and the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the technical field of hardware, in particular to a new type of high-strength mechanical hardware. Background technique [0002] In the process of mechanical installation, the motor and the shaft are generally used; the workpiece and the shaft are mostly connected by keys, and the workpiece and the shaft often do not fit during processing. Most of the workpiece and the spindle are directly welded, which causes inconvenience in later maintenance. Propose a new type of high-strength mechanical hardware suitable for the connection of shafts and workpieces [0003] However, the Chinese patent CN201721444221.3 discloses a new high-strength mechanical hardware, which often has the problem that the shaft hole of the workpiece does not match the main shaft during the machining process. If the workpiece and the main shaft are directly installed, the main shaft and the workpiece will There will be vibration between them, and the risk of...

Problems solved by technology

[0004] 1. In the prior art, a large amount of oil and dust will adhere to the surface of the workpiece after long-term use, which will easily cause corrosion of the thread on the surface of the bolt, resulting in inconvenient disassembly and maintenance in the later s
