Problems solved by technology

However, in the process of producing the same workpiece, it is often necessary to grind the edge of the hole on the workpiece after drilling, otherwise the edge of the hole is relatively sharp and easy to cause injury to the contactor, and the existing drilling machine is in operation. High-speed friction with the workpiece will generate a lot of debris, and the temperature of the tool and workpiece will increase, resulting in reduced work efficiency and instability of the drill bit

Abstract

The invention discloses a drilling machine. The drilling machine structurally comprises a rack, a vertical sliding device, a drilling machine body, a working plate, a support and a sliding rail table,wherein the drilling machine further comprises a driving shaft, a drill bit, a telescopic folding protection cylinder and a drill bit balance mechanism. According to the drilling machine, the drill bit is used for driving a drill bit clamping piece, a drilling grinding layer is driven to grind the edge of a hole opening when an arc-shaped piece body rotates, and the damage of the edge of the holeopening to a contact person is avoided. The design of the drill bit clamping piece is used for assisting in balancing the rotation stability of the drill bit and grinding the edge of the hole opening, negative pressure attraction force is generated through rotation of a negative pressure fan, chippings are concentrated in the telescopic folding protection cylinder, the chippings are prevented from drifting away, the drill bit can be cooled, and the heat loss of the drill bit is reduced.

Description

Technical field [0001] The invention relates to the field of drilling machines, in particular to a drilling machine. Background technique [0002] Drilling machine is a device used to complete the drilling of materials. It is widely used in the processing and production of office supplies, workpieces and fabrics. Existing drilling machines usually include motors, transmission mechanisms, drill bits and bases, and materials Placed on the base, the motor controls the drill bit to move down through the transmission system to drill the material fixed on the base. However, in the process of producing the same workpiece, it is often necessary to grind the hole edge of the punched workpiece, otherwise the edge of the hole is relatively sharp and will easily cause damage to the contacts, and the existing drilling machine is in operation due to the tool High-speed friction with the workpiece will produce a large amount of debris, and the temperature of the tool and workpiece will increas...
