The Clamping Mechanism of the Shaft of the Oval Fitting Machine

Abstract

The invention discloses an axle clamping mechanism of an elliptical jointing machine. Two sets of guide rails are fixed on a base plate, and four sets of sliders are inserted on the guide rails. Cylinder mounting plates are fixed on two sets of sliders at the left and the right end of the guide rails, a small-stroke cylinder is fixed on the cylinder mounting plate at the left end of the guide rails, a large-stroke cylinder is fixed on the cylinder mounting plate at the right end of the guide rails, pushers are fixed on piston rods of the small-stroke cylinder and the large-stroke cylinder, and respectively fixed onto two clamp mounting plates, an inverted L-shaped support is fixed on one side of the upper end face of each of the clamp mounting plates, fixing blocks with V-shaped notches are fixed on the L-shaped supports, clamping cylinders are fixed on the other sides of the upper end faces of the clamp mounting plates, and connecting rods are fixed on the piston rods of the clamping cylinders. Two short axles are in interference fit through double cylinders, and interference fit and press fit of the two short axles are completed on the same equipment so that time for feeding and discharging on different devices is saved and production efficiency is improved.

Description

Technical field: [0001] The invention relates to the technical field of pressing machines, and more specifically relates to a clamping mechanism for shaft rods of ellipse fitting machines. Background technique: [0002] At present, the long rod shafts on some cars are long in length, and the material cost of manufacturing and processing the whole long rod shaft is relatively high. Therefore, some existing long rod shafts are generally formed by forging or pressing multiple short shafts. The ellipse fitting machine is a device that presses multiple short shafts into a long shaft. Some existing long shafts composed of short shafts generally insert one short shaft into the other short shaft before pressing, and the connecting parts of the two short shafts are generally interference fit, and the simple use of manual Assembling is difficult to realize. The existing processing method is to vertically press one short shaft into another short shaft, but for some longer long shafts,...

AI Technical Summary

Problems solved by technology

Some existing long shafts composed of short shafts generally insert one short shaft into the other short shaft before pressing, and the connecting parts of the two short shafts are generally interference fit, and the simple use of manual Assembling is difficult to achieve. The existing processing method is to vertically press one short shaft into another short shaft, but for some long long shafts, general hydraulic presses cannot meet their length requirements

However, the short axis is plugged first, and then the contact point is pressed, and it is taken in and out on unused equipment, which takes a long time and the production efficiency is not high.
