Verticality Monitoring Device for Tool Holder Movement of Vertical Hobbing Machine

Abstract

The invention specifically discloses a motion perpendicularity monitoring device of a tool rest of a vertical gear hobbing machine. The device comprises a rack, a detection table, a feeding tank and a hydraulic cylinder. The detection table comprises a supporting plate and a movable plate. The lower portion of the supporting plate is movably hinged to the rack. The upper plate surface of the supporting plate is a concave arc surface. The supporting plate is provided with a groove frame, and the movable plate is located in the groove frame. The left side of the movable plate is movably hinged to the supporting plate. A tension spring is arranged between the lower left portion of the supporting plate and the rack. One end of the tension spring is movably hinged to the rack, and the other end of the tension spring is movably hinged to the supporting plate. The hydraulic cylinder is movably hinged to the rack. A piston rod of the hydraulic cylinder is movably hinged to the lower portion of the movable plate. A drawing edge is arranged on the right side of the supporting plate, and the lower portion of the drawing edge is arc. The feeding tank is provided with a drawing tank allowing the drawing edge to pass through. The feeding device does not need to be guarded manually, and thus operators can do other things during detection of gears.

Description

technical field [0001] The invention relates to the technical field of gear production equipment, in particular to a verticality monitoring device for tool rest movement of a vertical gear hobbing machine. Background technique [0002] Gear hobbing machine is the most widely used machine tool in gear processing machine tools. It can cut straight teeth, helical gears, cylindrical gears, turbines and sprockets, etc., and belongs to the process of processing straight teeth, helical teeth, and herringbone by hobs according to the expansion method. Gear machining machines for teeth, spur gears and worm gears. This machine tool can also process various special tooth shapes such as splines and sprockets when using a special hob. [0003] Gear hobbing machines are divided into vertical and horizontal types according to the structure. When the vertical gear hobbing machine is working, the hob is installed on the hob spindle, and the hob is driven by the main motor to rotate, and th...

Problems solved by technology

However, during the processing of the vertical hobbing machine, the verticality of the hobbing machine’s tool holder moving up and down mainly depends on the verticality of the guide rail. Once the guide rail wears too much, the tool holder of the gear hobbing machine is prone to deflection, resulting in the occurrence of knife punching. Phenomenon, serious and even directly lead to the scrapping of the hob

The existing gear hobbing machine is not equipped with a device to detect the trajectory of the tool holder, and there is no device for correcting the trajectory of the tool holder.
