Adjustable scrap prevention cover

Abstract

The invention discloses an adjustable scrap prevention cover. The adjustable scrap prevention cover includes a cover shell, a clamp fixing frame, a lifting shaft and a connector, wherein the upper portion and lower portion of the cover shell are communicated; the clamp fixing frame and the connector are connected with the upper portion and the top of the lifting shaft respectively, and the connector is connected with the cover shell. When a drill is in work, generated iron scraps can be effectively blocked and are prevented from flying apart and causing environment pollution. The adjustable scrap prevention cover is fixed on a main shaft of a main shaft box and can synchronously move up and down along with the main shaft. The lifting shaft can move up and down in a sleeve of the clamp fixing frame, the height of the cover shell can thus be adjusted, and it is ensured that the cover shell is on the periphery of the drill. The lifting shaft and the connector are rotatably connected through a rotating shaft, the cover shell and the connector as a whole can rotate relative to the lifting shaft, the angle of the cover shell is thus adjusted, and it is ensured that the cover shell is always in a horizontal protection state. The cover shell is formed by hinging a left cover shell body and a right cover shell and thus is convenient to open and close.

Description

technical field [0001] The invention relates to the field of drilling and milling machine processing, in particular to an adjustable anti-dust cover applied to the drill bit of the drilling and milling machine. Background technique [0002] Drilling and milling machine is a small and medium-sized general-purpose metal cutting machine tool, which can not only perform horizontal milling, but also vertical milling. It is suitable for drilling, expanding, reaming, boring, and hole processing; it can mill planes, inclined surfaces, vertical surfaces and grooves, etc. After installing the accessory dividing head, it can be used for milling of spur gears, bevel gears and helical gears with modulus m=3mm or less. Because this machine tool is widely used, it is suitable for general repairs and tool workshops. It is suitable for use in single-piece or small-batch production workshops. It has the advantages of simple structure and flexible operation. See image 3 , the structure of t...

Problems solved by technology

See image 3 , the structure of the machine tool is mainly composed of a base 01, a workbench 02 installed on the base, a column 03, and a headstock 04 connected to the top of the column 03. The headstock is connected with a drill 05 extending downward, but the drill When drilling parts, a large amount of iron filings will be generated, and the iron filings will fly around due to the centrifugal force of the drill bit, causing environmental pollution, and the iron filings are difficult to clean
