Safety protection device for chamfering drill

Abstract

The invention discloses a safety protection device for a chamfering drill, and belongs to the technical field of mechanical structures. The safety protection device comprises an upper clamping drum, alower clamping drum and a transparent cover, wherein each of the upper clamping drum and the lower clamping drum comprises a center part and clamping drum lug rings extending out from the center part; the clamping drum lug rings of the upper clamping drum and the lower clamping drum are connected through connecting rods; a moving ring and a static ring which are in contact with each other in an embedded manner are arranged at the center of the lower clamping drum; the transparent cover with an opening is connected onto the moving ring; a protection cover is connected with the outer side at the lower end of the transparent cover; each of the connecting rods is sleeved with a spring, a thread is arranged on each of the connecting rods, and an upper nut and a lower nut are connected onto each of the connecting rods, so as to form a height adjusting device for adjusting the lower clamping drum; and the springs are arranged on the connecting rods in a sleeving manner. The safety protectiondevice for the chamfering drill has the benefits as follows: iron chips produced by chamfering are completely isolated from the outside and prevented from spattering, operators are prevented from injured by iron chips, the sanitation problem of the working environment where iron chips spatter is solved, and unnecessary potential safety hazards are reduced.

Description

technical field [0001] The invention belongs to the technical field of mechanical structures, in particular to a safety protection device for chamfering drills. Background technique [0002] "Safety first, prevention first". In the production, processing and manufacturing industry, personal safety is getting more and more attention. When technicians complete various processing and production tasks, they must fully consider safety and put the personal safety of operators first. prime position. In the field of mechanical processing and production, most parts need to be chamfered during the production process, and the corners of the holes can be chamfered with a bench drill for parts with small volume and weight. Bench drill is a kind of small size and easy to operate. When chamfering, the drill bit is clamped on the drill bit holder, and the drill bit holder is tightened with a fixed wrench. The main movement of the drill bit and the drill bit holder is driven by the main sha...

Problems solved by technology

[0003] Usually when using a drilling machine for chamfering, the drill bit rotates at high speed, the operator's face is very close to the machine tool, and there are no protective facilities around the bench drill, iron filings splash around under the action of centrifugal force during chamfering, or due to improper chamfering force, Chips cannot be broken naturally, and long iron filings stick to the tool and rotate with the tool at high speed, causing potential dangers such as strains and burns to the operator; when female workers are operating, if they do not wear work clothes and hats according to the operating procedures, and have long braids Or clothes and accessories are easily drawn into the main shaft, causing personal injury; iron filings splashing on the ground not only affects environmental sanitation, but also causes poor flow of people and logistics channels in the workshop, bringing a lot of inconvenience and safety hazards to production; iron filings splashing adheres to the On the mold, it is easy to cause product scratches and affect the quality of chamfering
