Double-side double-station force control belt sander and polishing work station thereof

Abstract

The invention provides a double-side double-station force control belt sander and a polishing work station thereof. The double-side double-station force control belt sander comprises single-station polishing cabinets and a power output cabinet. The two single-station polishing cabinets are arranged. The power output cabinet is arranged between the two single-station polishing cabinets. Each single-station polishing cabinet comprises a polishing system composed of a polishing driving wheel, a polishing abrasion wheel, a polishing driven wheel and a polishing abrasion belt, wherein the polishingabrasion belt is arranged on the polishing driving wheel, the polishing abrasion wheel and the polishing driven wheel in a winding manner. Each single-station polishing cabinet further comprises a force control mechanism and a deviation rectifying mechanism, wherein the force control mechanism drives the polishing abrasion wheel to move linearly, and the deviation rectifying mechanism drives thepolishing driven wheel to swing around one side. The power output cabinet comprises a polishing motor and a transmission shaft. The polishing motor drives the transmission shaft to rotate. The two ends of the transmission shaft are connected with the corresponding polishing driving wheels. The polishing quality and efficiency of the belt sander are improved, sensitivity of force control is high, the polishing applicability is high, the polishing performance is reliable, the abrasion belts are convenient and fast to replace, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to an abrasive belt machine, in particular to a double-side double-station force-controlled abrasive belt machine and a grinding workstation thereof. Background technique [0002] At present, the abrasive belt machine is widely used in automatic production equipment; but the existing belt machines generally have the following problems: [0003] 1. During the grinding process, the replacement frequency of the abrasive belt is high, but the replacement is difficult, resulting in a decrease in production efficiency; [0004] 2. The single-column single-side double-station abrasive belt machines on the market, due to the unreasonable force on the single-side structure, the drive shaft is easily deformed, so it is difficult to guarantee the grinding quality; [0005] 3. The grinding position of the belt machine is fixed. When there is a difference in the product, there will be a grinding defect if it is light, and it will damage the g...

AI Technical Summary

Problems solved by technology

[0003] 1. During the grinding process, the replacement frequency of the abrasive belt is high, but the replacement is difficult, resulting in a decrease in production efficiency;

[0004] 2. The single-column single-side double-station abrasive belt machines on the market, due to the unreasonable force on the single-side structure, the drive shaft is easily deformed, so it is difficult to guarantee the grinding quality;

[0005] 3. The grinding position of the belt machine is fixed. When there is a difference in the product, there will be a grinding defect if it is light, and it will damage the grinding equipment when it is serious, resulting in a decline in the qualified rate of workpiece grinding and shortening the service life of the equipment;

[0006] 4. The existing force control structure is complicated, and usually needs to drive the two abrasive belt wheels of the entire rocker arm to move together, resulting in large inertia, high energy consumption, and insensitive response;

[0007] 5. Double-deck double-station structure, high column, complex structure, requires two motor drives, high cost

The structure of the abrasive belt machine is complex and involves many parts, which makes it difficult to replace the abrasive belt, the energy consumption of the drive motor is high, and the response of the abrasive belt is slow
