Embodiment Construction

[0019] Accompanying drawing is a kind of specific embodiment of the present invention. The assembly steps of this embodiment are:

[0020] (1) Assembling: the handle seat 4 and the gear cover 3 are assembled together, assembled in place, the friction part of the gear cover 3 and the handle seat 4 is coated with a sufficient amount of grease, and then the handle seat 4 is assembled and decorated successively. Cover 2, plastic spring 7, the square structure of the gear cover 3 and the square hole of the handle 1 are assembled together, and the special tool is gently smashed to install the gear cover 3, and the assembled handle 1 is put into the assembly line and flows into the next station.

[0021] (2) Pressure riveting: After assembly, the handle 1 is placed in the special mold, and the riveting machine and the special riveting head are pressed into the gear cover, so that the gear cover 3 and the handle 1 are assembled in place, firm without looseness, and without backlash. ...

Abstract

This invention relates to the field of lever handles for plastic steel windows, particularly discloses an assembly process of a shift-sleeve-structure lever handle for a plastic steel window. Based on a traditional shift-sleeve-structure lever handle for the plastic steel window, the assembly process of the shift-sleeve-structure lever handle for the plastic steel window utilizes assembly line work for following processes to achieve a semi-automated continuous production operation, and additionally arranges a rivet pressing process of a shift sleeve and the lever handle between a lever handle seat part assembly and a cross recessed countersunk head screw handling. The assembly process of the shift-sleeve-structure lever handle for the plastic steel window is simple and reasonable in design, utilizes the shift sleeve and the lever handle to be assembled in place to leave no rebound space to further ensure the consistency and the stability of the quality of the lever handle, and can be popularized and applied widely.

Description

(1) Technical field [0001] The invention relates to the field of handles for plastic-steel windows, in particular to an assembly process for handles for plastic-steel windows with a shift cover structure. (2) Background technology [0002] Although China is currently classified as a developing country, its economy is in a stage of rapid development. The rapid development of China's economy has driven the rapid development of the construction industry and the construction supporting hardware industry, and the demand is increasing. The window handle is a key part of each set of window hardware. The quality of the handle directly affects the use of the window. [0003] However, there is a drawback in the current window handles. After the handles are assembled, the handles are in good condition in the early stage of use. However, after a period of use, the radial clearance of the handle shaft increases, and the use effect is significantly reduced. (3) Contents of the inven...
