Description

Technical Field

[0001] The utility model relates to a drilling and deburring machine, in particular to a new end cover drilling and deburring machine. Background Art

[0002] With the progress and development of society, the previous labor-intensive production model is no longer suitable for the development of modern enterprises. The labor cost is high and the efficiency is low. The use of automated production equipment for production can significantly reduce the production cost of enterprises, improve the reliability and safety of production, provide users with high-quality and low-cost products, and enhance the competitiveness of the company's products in the market. Fig. 9 and Fig.10 As shown, the surface of the circular end cap 1a product cannot be guaranteed to be neatly cut at the final center point during cutting due to lathe turning. Under the influence of the cutting force, a small tail nail 2a will be automatically left in the center of the end cap surface. It is necessary to remove the tail nail 2a. In addition, drilling is required after the end cap 1a of the door closer removes the tail nail 2a. The traditional processing method is to transform and improve it through manual operation and single process processing mode. The drilling of the two process holes 3a of the end face of the door closer end cap 1a requires the end caps to be placed on the manual drilling machine processing fixture one by one, aligned, and then the foot-operated pneumatic switch is activated, the cylinder presses the product, and then the bench drill is manually pulled down to drill the end cap. After processing, the product is taken out. After a batch is processed, it is put on the plane sanding machine, and the end cap is manually grasped and the tail nail 2a at the center of the end is ground. The operation is relatively cumbersome, and personnel are required to manually place and take materials throughout the process, resulting in increased labor costs, and the working environment is poor and there are safety hazards. Moreover, the work efficiency and product quality are limited, and the high turnover of operating staff and the difficulty in recruiting skilled technical workers directly affect the production efficiency of the products.

[0003] The surface of the end cap product cannot be cut neatly at the final center point due to lathe turning. Under the influence of the cutting force, a small tail nail will be automatically left in the center of the end cap surface, so it is necessary to remove the tail nail. The shape of this tail nail is sometimes irregular, some are large and some are small. When using a tool for processing, the selection of the tool is very important. After many tests, it was finally selected that a Ø10 ball cutter can complete the removal of the tail nail. The final contact point of the ball cutter with the plane can be concave about 0.3 ball head, which has no effect on the appearance and use of the product. Utility Model Content
