Problems solved by technology

[0002] In the prior art, the gear distribution box is used to distribute the power of the main shaft to each drill shaft through gears for the processing requirements of drilling multiple holes at the same time. Each drill shaft is positioned by bearings, but due to the radial Due to the large size, the gear distribution box must increase the radial space, so that the distance between the drilling shafts must be greater than the diameter of the gear and the bearing. For the drilling requirements with a small hole spacing, the gear distribution box must be used. way is not possible

Abstract

The invention discloses a short-wheelbase drilling device comprising a power device (3). The short-wheelbase drilling device is characterized in that an output shaft of the power device (3) is connected with a spindle crank (4) and penetrates a drill box (6), the other end of the drill box (6) is provided with a feed screw (7), the lower end of the spindle crank (4) is connected with a rotary disc (5), a group of drill shaft cranks (2) is arranged on the rotary disc (5), and the lower ends of the drill shaft cranks (2) are provided with drill bits (9) arranged on the drill box (6). By the aid of rotation of the cranks, the spindle crank transmits power onto the rotary disc, the rotary disc continuously rotates around the spindle crank and further drives the drill shaft cranks below to rotate, and the drill bits are mounted at the lower ends of the drill shaft cranks, so that multiple holes can be drilled in workpieces at one time.

Description

technical field [0001] The invention relates to a drilling device, in particular to a short-axisbase drilling device. Background technique [0002] In the prior art, the gear distribution box is used to distribute the power of the main shaft to each drill shaft through gears for the processing requirements of drilling multiple holes at the same time. Each drill shaft is positioned by bearings, but due to the radial Due to the large size, the gear distribution box must increase the radial space, so that the distance between the drilling shafts must be greater than the diameter of the gear and the bearing. For the drilling requirements with a small hole spacing, the gear distribution box must be used. method cannot be realized. This is the weak point of prior art. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a short-axisbase drilling device, which realizes simultaneous drilling of densely packed and small-pit...
