Simple hinge type manual feeding and discharging device for shaft hobbing

Abstract

The invention discloses a simple hinge type manual feeding and discharging device for shaft hobbing. The simple hinge type manual feeding and discharging device for shaft hobbing comprises two link rods. The lower ends of the two link rods are fixedly connected with a hinge bracket. The upper ends of the link rods are connected with a machine tool tailstock through transition flanges. A lower limiting bracket is arranged below the hinge bracket, fixed to a machine tool stand column and used for limiting the lower extreme position of the hinge bracket. During machining, the lower end of a workpiece stretches into a clamp body and rotates along with a workbench after being clamped; the machine tool tailstock moves up and down to drive a whole mechanism and the workpiece to move up and down, and thus the workpiece can be placed in and taken out of the clamp body. By designing the simple hinge type feeding and discharging device and fixing the simple hinge type feeding and discharging device onto the machine tool tailstock, the workpiece is taken out of the clamp body by means of the upward movement of the tailstock when a machine tool is loosened; then the workpiece is rotated out of the center of a clamp to reach a position in front of a protective door through a hinge type rotary mechanism, and discharging operation is conducted by a worker. The feeding action is conducted in the sequence opposite to the discharging action.

Description

【Technical field】 [0001] The invention belongs to the technical field of mechanical processing, and relates to a simple hinge-type manual loading and unloading device for gear hobbing of shafts. 【Background technique】 [0002] The gear hobbing of shaft parts often adopts the clamping scheme of double centering and external circle clamping drive. For heavy-duty transmission intermediate shaft parts, due to the complex structure and heavy weight (such as our company's 7DS100 intermediate shaft, with a total length of 595mm and a weight of more than 30 catties), the workpiece needs to be lifted and pulled out when loading and unloading the workpiece during gear hobbing, and the labor intensity is very high. big. [0003] As a special configuration of the machine tool, the shaft hobbing loading and unloading mechanism can be selected when purchasing the machine tool. It can be realized by adding an exchange manipulator on the machine column. The price of a single set of configur...

For heavy-duty transmission intermediate shaft parts, due to the complex structure and heavy weight (such as our company's 7DS100 intermediate shaft, with a total length of 595mm and a weight of more than 30 catties), the workpiece needs to be lifted and pulled out when loading and unloading the workpiece during gear hobbing, and the labor intensity is very high. Big

[0003] As a special configuration of the machine tool, the shaft hobbing loading and unloading mechanism can be selected when purchasing the machine tool. It can be realized by adding an exchange manipulator on the machine column. The price of a single set of configuration exceeds 1 million, and the cost of retrofitting the old machine tool is even higher.
