Tablet press rotating disc drilling method and concentric positioning device applied to method

Abstract

The invention discloses a tablet press rotating disc drilling method and a concentric positioning device applied to the method, belongs to the technical field of pharmaceutical machinery processing and manufacturing, and solves the problems of multiple procedures, low production efficiency, high labor intensity and high production cost of a traditional tablet press rotating disc drilling method. Products are machined mainly through a concentric positioning mode and a split type drill bit design. According to the method and the positioning device, the conception is novel and ingenious, the traditional rotating disc machining procedure is greatly simplified, the production cost of an enterprise is greatly reduced, the labor intensity of workers is greatly reduced, the precision of machined products is high, and considerable economic benefits are brought to the enterprise.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical machinery processing and manufacturing. Specifically, it relates to a drilling machine with fast drilling speed, which can greatly reduce the labor intensity of workers, can greatly improve the production efficiency of enterprises, and can process products with high precision and structural concept. The invention relates to a method for drilling holes in a turntable of a tablet press, which is simple and ingenious in design and effectively reduces the production cost of the turntable of the tablet press, and a concentric positioning device applied in the method. Background technique [0002] Rotary tablet press machine is a double-press type automatic rotary and continuous tablet press machine, which compresses granular raw materials into tablets. It is mainly used in the production of tablets in the pharmaceutical industry, and is also suitable for chemical, food, electronics and other indu...

AI Technical Summary

Problems solved by technology

[0003] It can be seen from the above that the traditional rotary table drilling method mainly has the following problems: 1. Every workpiece needs to manually draw a line to find the center of the circle. Obviously, the efficiency of manually drawing a line to find the center of the circle will be very low. The product scrap rate is also high; 2. In order to make the drill bit to process the equal-round through hole C, the turntable to be drilled must be raised. The traditional spacer can play a role in raising the height, but the position of the spacer needs to be constantly changed according to the position of the drilled hole , Lock the pressure plate-loosen the pressure plate-adjust the cushion block-relock the pressure plate again, such an operation step needs to be operated many times for a product, which is a waste of time, the production efficiency is very low, and the labor intensity of the staff is also very high; 3. Drilling machine The drill bit is aligned with the center of the circle with the naked eye, and there will be errors to some extent. There is no self-correction function in the processing process, and the precision of the processed product is relatively poor. If the error is large, the product will be scrapped directly; 4. A drilling machine cannot independently complete the turntable. For processing, the diameter of the drill bit is a fixed value. The drill bit of the traditional drilling machine cannot pass through the equal-circle through hole A to expand the equal-circle through-hole B. To expand the hole, the boring tool of the boring machine is required. The boring tool has a telescopic function and can pass through the equal-circle through-hole A for processing. Equal round through hole B, but frequent tool setting is required in this process; generally there are nine equal round through holes A on the turntable, that is to say, nine times of tool setting are required to process one turntable, which is labor-intensive and time-consuming, which is greatly reduced again. Product production efficiency; in addition, the enterprise needs to purchase two sets of equipment, and the processing cost is high; 5. The product needs to be transported from the drilling machine to the boring machine, and the minimum size of the turntable of the tablet press is 40 kg. The manpower, material resources, and The time and cost will reduce the production efficiency of the enterprise again; 6. The tool setting of the boring machine is a technical work, and there is a high requirement for the experience of the master
