Clamping mechanism for full-automatic internal polishing machine

Abstract

The invention discloses a clamping mechanism for a full-automatic internal polishing machine. The clamping mechanism comprises a main supporting frame, a rotating motor, rotating trays, a propelling air cylinder, a pressing air cylinder and rear end pressing mechanisms. Two clamping stations are arranged on the main supporting frame. Each clamping station comprises one rotating tray and one rear end pressing mechanism, wherein the rear end pressing mechanisms are connected with the pressing air cylinder. The rotating trays are connected with the rotating motor. The rotating motor, the propelling air cylinder and the pressing air cylinder are installed on the main supporting frame. According to the clamping mechanism, the rotating trays are matched with the propelling air cylinder, and a rear end pressing head is matched with the pressing air cylinder, so that workpieces are pressed and fixed; and meanwhile, the rotating trays are matched with the rotating motor, and the workpieces can spin when pressed under the cooperation of the rotatable rear end pressing head, so that the two workpieces can work continuously at the same time conveniently, the automation degree is high, the production efficiency is greatly improved, and the labor intensity of workers is relieved.

Description

technical field [0001] The invention relates to the technical field of polishing equipment accessories, in particular to a clamping mechanism applied to internal polishing equipment. Background technique [0002] Circular metal-like products with inner cavities are widely used in various industries. Such products need to be polished on their inner walls to remove rust, stains, etc. on the inner walls. Whether effective rust removal can be achieved can be said to be the The core of product quality control. The traditional method is generally completed by high-pressure sandblasting and washing, but the shortcomings of this traditional washing and rust removal method are that rust removal and polishing are not thorough, and there are also simple equipment, low degree of automation, serious pollution, labor Insufficient strength, etc.; Another method is to put steel grit into the workpiece, and drive the workpiece through mechanical transmission to shake the bottle bottom and b...

Problems solved by technology

The traditional method is generally completed by high-pressure sandblasting and washing, but the shortcomings of this traditional washing and rust removal method are that rust removal and polishing are not thorough, and there are also simple equipment, low degree of automation, serious pollution, labor Insufficient strength, etc.; Another method is to put steel grit into the workpiece, and drive the workpiece through mechanical transmission to shake the bottle bottom and bottle mouth left and right while rotating, so that the steel grit will rub against the inner wall of the workpiece to achieve rust removal and polishing. purpose, but this method has the disadvantages of high equipment energy consumption, high labor intensity for upper and lower sand materials, low polishing efficiency, large vibration, and large noise.

Although someone has invented a clamping device that can fix the workpiece for sandblasting and polishing, the current clamping device can only simply clamp and fix the workpiece, which is inconvenient to realize the attitude adjustment of the workpiece, such as loading it in a horizontal posture, and then Through the cooperation of other mechanisms, the workpiece can be erected to facilitate subsequent polishing operations

At the same time, the existing clamping equipment is not easy to realize the autonomous rotation of the workpiece, which leads to a long time consumption in the process of loading, unloading and polishing, and requires more manpower assistance
