Assembly mechanism and assembly method of rotating shaft steel ball

Abstract

The invention discloses an assembling mechanism of rotary shaft steel balls. The assembling mechanism comprises an air pump, a main body part, a bottom plate, a guiding column and a piston, wherein acavity which penetrates through the upper surface and the lower surface of the main body part is disposed in the main body part; the bottom plate is fixed to the lower portion of the main body part; the guiding column is installed in the main body part; the guiding column is sleeved with the piston; a mounting seat of a shaft barrel is disposed above the guiding column; a plurality of round holeswhich are arranged regularly into a circle are formed in the upper end of the piston; a plurality of oblique holes penetrating through the wall surface are formed in the surface of the main body part;the oblique holes are in one-to-one correspondence with the round holes; the air pump passes through an electromagnetic valve to be divided into an upper pipeline, a middle pipeline and a lower pipeline which lead to the upper portion of the main body part, the lower portion of the main body part and the bottom plate correspondingly; the upper pipeline is located on the upper portion of the piston, the middle pipeline is located on the lower portion of the piston; the lower pipeline is connected to an air path disposed on the bottom plate; the air path leads to the guiding column and the mounting seat; a first air hole assembly which corresponds to the round holes and communicate with the air path is disposed on the guiding column; and a second air hole assembly which is distributed identically to the first air hole assembly is disposed on the mounting seat. Assembling of a rotary shaft is achieved, and whether mounting of the steel balls is omitted or not is detected synchronously.

Description

technical field [0001] The invention relates to a mechanical assembly mechanism, in particular to an assembly mechanism of a rotating shaft steel ball and an assembly method thereof. Background technique [0002] Now our company has a shaft product, such as figure 1 Shown: including the shaft tube 00, the lower end of the shaft tube 00 is provided with a circle of regularly arranged installation holes 02, steel balls 03 should be installed on the installation holes 02, and the shaft sleeve 01 is arranged outside the installation holes of the shaft tube 00. [0003] On the existing assembly line, the most common way is to adopt the manual installation mode. Firstly, various fixtures are required on the assembly line, which are used to fix the shaft tube, to clamp the steel ball, and to set the shaft sleeve. In addition, it is also necessary to prevent the steel ball in the small hole from falling out during the assembly process. In the existing method, solid lubricating oil...

Problems solved by technology

[0004] However, whether it is the assembly method of the rotating shaft or the fixing method of the steel ball, the efficiency is very low. Not only are there many tools, but also the operation time is long and the labor cost is high.

Moreover, it is difficult to guarantee the quality of the product during the manual operation process, and there will be situations where steel balls are missing.
