Abstract

The invention discloses a plate punching device with a variable-diameter drill head. A frame is connected with a control console and a motor; the motor is connected with a cylinder; the cylinder is connected with a rotary disc; the rotary disc is connected with the drill head and provided with a first through hole; the drill head comprises a small drill head and a diameter increasing drill head; the diameter increasing drill head is provided with an open pore; a drill body is in spline connection with the diameter increasing drill head; a gear is rotationally arranged on the drill body; a second through hole is formed in the drill body; racks are arranged in the first through hole and the second through hole in a sliding mode; the gear is engaged with the racks; a plurality of gear teeth are arranged on the inner wall of the diameter increasing drill head and engaged with the gear; a groove is formed in the drill body; an arc block is arranged in the groove in a sliding mode; a spring is connected between the arc block and the inner wall of the groove; an iron block is connected to the arc block; and a solenoid is arranged inside the groove. Compared with the prior art, the plate punching device has the advantages that the diameter of the drill head can be conveniently adjusted and pores with different pore diameters can also be machined in plates.

Description

technical field [0001] The invention relates to the field of furniture processing equipment, in particular to a plate punching device with a variable diameter drill bit. Background technique [0002] Beds, recliners, etc. are commonly used furniture in people's lives. These furniture are usually spliced ​​by panels. Drilling is to manually use a drill to drill holes in the plate, which has low efficiency and high work intensity. [0003] In order to solve the above problems, the existing patent document with application number 201010613582.2 discloses a drilling machine, which includes a motor and a machine needle, and the needle is equipped with a point heating device, and the point heating device gradually heats by radiation. [0004] Although this drilling machine can complete the drilling of the plate, when holes of different diameters need to be opened on the plate, it is necessary to manually replace the drill bit according to the size of the hole to be drilled on the...
