Rotary combined tray for forklift transmission assembly

Abstract

The invention discloses a tray for forklift transmission assembly. The tray is mainly formed by combining a main tray and an auxiliary tray, wherein the lower part of the main tray is provided with a double-layer horizontal rotating and positioning mechanism, and the upper part of the main tray is provided with a vertical rotating and positioning mechanism; and the auxiliary tray has a disc-shaped structure of which the diameter is the same as that of a flange disc on a transmission. The tray has the advantages of being wide in applicability, low in labor intensity, high in safety, high in efficiency and ensured in quality; the tray can be matched with assembly of five postures of multiple transmissions; the main tray and the auxiliary tray are matched, so that the transmissions can conveniently rotate along an axis of the flange disc, and the labor intensity is greatly reduced; the tray horizontally rotates, so that the forklift transmission operates on a single side is solved, and the position is not required to be changed back and forth; and due to the positioning function of the tray, online automatic press fitting, turning and screwing of the forklift transmission are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing equipment, and in particular relates to a rotary combined pallet used for assembling a forklift gearbox. Background technique [0002] There are generally two to three assembly surfaces for automobile gearboxes. Compared with automobile gearboxes, forklift gearboxes have one more helical gear pair to change the transmission direction and two more operating surfaces. There are five surfaces in total that need to be assembled. At present, the assembly of the forklift gearbox is carried out on a flat operating platform, and the operating platform is fixed. Since the clearance adjustment is required during the assembly of the helical gear pair, the position of the forklift gearbox needs to be adjusted back and forth repeatedly. The existing assembly method is to change the position by manually dragging the gearbox to turn over. When turning over, the flange at one end of the gearbox is u...

AI Technical Summary

Problems solved by technology

The existing assembly method is to change the position by manually dragging the gearbox to turn over. When turning over, the flange at one end of the gearbox is used as a fulcrum, and the other end is manually lifted to rotate the box along the flange. The operation is labor-intensive.

At the same time, due to the non-standard shape at the other end of the gearbox, the rotated gearbox is inclined on the platform; for some assembly processes of the forklift gearbox, the two sides of the gearbox can only be completed by changing the position of the operator. Assembly work

The disadvantages of the existing assembly technology are: 1) High labor intensity: the irregular shape of the gearbox brings great difficulties to manual lifting and turning, and the labor intensity is high; 2) The assembly quality is not high: because the workpiece is not positioned, it cannot be realized on-line Automatic pressing, turning and tightening, etc., have a low degree of automation and assembly quality is difficult to guarantee; 3) Low assembly efficiency: Forklift gearbox assembly requires double-sided operations, and changing the operating position back and forth is time-consuming and laborious, which greatly reduces assembly efficiency; 4) Safe operation Poor performance: During the process of manual lifting and turning over, the gearbox uses one end as the fulcrum, which is easy to slip sideways and poses a safety hazard; at the same time, the workpiece is placed obliquely on the operating table, which has poor stability; the flange of the workpiece is tangent to the operating table, and when placed Without positioning and locking, it is easy to rotate during assembly, which reduces the safety of operation
