Movable isolation equipment for bevel gear-looth-grinding machine grinding cabin

Abstract

The invention provides a movable isolation device for a grinding chamber of a bevel gear grinding machine. Its characteristics are: the upper end of the grinding chamber is equipped with a beam and a slideway, the slideway is equipped with a left and right side door, two cylinders are installed on the beam to drive the left and right side door, and a frame-shaped fixed plate is installed on the back side of the grinding room. The upper and lower ends of the fixed plate are respectively installed with a horizontal upper platen and a horizontal lower platen with side grooves on the inner side, a frame-shaped horizontal slide plate that moves left and right is installed in the side grooves of the horizontal upper and lower platens, and a frame-shaped horizontal slide plate is installed on both sides of the frame-shaped horizontal slide plate. The vertical left upper and lower pressing plates and the longitudinal right upper and lower pressing plates with side grooves on the inner side are equipped with vertical sliding plates that move up and down in the side grooves of the longitudinal left upper and lower pressing plates and right upper and lower pressing plates. The hole and sealing ring and the corrugated telescopic oil-resistant rubber sleeve connected to the main shaft greatly improve the corrosion resistance and sealing performance of the main shaft movable isolation device. In addition, the invention also has the advantages of simple structure, convenient loading and unloading of workpieces, energy saving and long service life.

Description

technical field [0001] The invention relates to a gear grinding machine for gear finishing, in particular to a movable isolation device for a grinding chamber of a bevel gear grinding machine. Background technique [0002] Bevel gear grinding machine is a common equipment for bevel gear finishing. The processing method is to install a pair of bevel gears meshing with each other on the two main shafts, and finish machining by adding grinding fluid and applying torque between the two gears at the same time. In order to prevent the grinding liquid from splashing during processing, the general bevel gear grinding machine is equipped with its own grinding chamber and movable isolation device for the main shaft. The most common is a rubber-type movable isolation device, which has an up and down movable switch door, and the two main shafts are isolated from the inside and outside of the grinding room by rubber materials. Small, not conducive to loading and unloading workpieces; t...

Problems solved by technology

The most common is a rubber-type movable isolation device, which has an up and down movable switch door, and the two main shafts are isolated from the inside and outside of the grinding room by rubber materials. Small, not conducive to loading and unloading workpieces; the other is a semi-arc type switch door, a sandwich type movable plate isolation device, its structure is more complicated, it has a hydraulic cylinder as power to drive a semi-arc type door opener composed of multiple arcs Due to the long-term erosion of the abrasive liquid, it is easy to wear and leak the abrasive liquid between the arcs of the joints. The sandwich type isolation device is also prone to leakage of the abrasive liquid after a certain period of time, which will cause damage to the moving parts outside the grinding chamber. damage

Grinding fluid leakage also causes environmental pollution
