Plate punching device capable of automatically replacing drill bits

Abstract

The invention discloses a plate punching device capable of automatically replacing drill bits. The device comprises a frame body, a cross beam and a punching assembly; the frame body includes a base, and stand columns fixed on the left and right sides of the top of the base; first cavities are arranged in the punching assembly in a bilateral symmetry manner; a second cavity is formed at the part, above the first cavities, in the wall body of the punching assembly; guide grooves arranged in a manner of extending up and down are respectively formed in the inner side walls of the first cavities on the left and right sides; transmission cavities are formed in the parts, above the guide grooves, in the wall body of the punching assembly; first rotating shafts arranged in a manner of extending up and down are arranged on the sides, far away from the guide grooves, of the first cavities; the top extension sections of the first rotating shafts penetrate through the inner top walls of the first cavities and extend into the second cavity; first bevel gears are fixedly arranged on the outer surfaces of the parts, positioned at the bottoms of the first cavities, of the first rotating shafts; a second rotating shaft is arranged in the center position of the inner wall of the second cavity; and the top of the second rotating shaft is connected with a first motor in a matched manner. The device is simple in structure, reasonable in design and convenient to operate, improves the punching efficiency, and is stable in operation and high in precision.

Description

technical field [0001] The invention relates to the technical field of plate processing, in particular to a plate punching device capable of automatically switching drill bits. Background technique [0002] At present, due to its convenient processing and certain strength, plates are widely used in our production and life, and are closely related to each of us. Plates are used by us to build houses, decorate indoor environments, and make indoor furniture. In the process, especially the processing of wood boards, it is necessary to punch holes in the wood boards according to the needs. The traditional wood board punching device generally uses the worker to hold the punching head to punch the wood boards. The labor intensity of the workers is relatively high, and the work efficiency Low, especially when it is necessary to punch multiple round holes at equal intervals on a wooden board, due to the randomness of the worker's operation, it is difficult to accurately punch holes o...

[0002] At present, due to its convenient processing and certain strength, plates are widely used in our production and life, and are closely related to each of us. Plates are used by us to build houses, decorate indoor environments, and make indoor furniture. In the process, especially the processing of wood boards, it is necessary to punch holes in the wood boards according to the needs. The traditional wood board punching device generally uses the worker to hold the punching head to punch the wood boards. The labor intensity of the workers is relatively high, and the work efficiency Low, especially when it is necessary to punch multiple round holes at equal intervals on a wooden board, due to the randomness of the worker's operation, it is difficult to accurately punch holes on the wooden board, which affects the quality of the punching of the wooden board. In addition, in the drilling operation The medium drill bit is easy to wear or damage. At this time, the drill bit needs to be replaced manually. The operation is complicated and affects the drilling process. The existing automatic drilling mechanism also has the drill bit worn or damaged during drilling. Workers manually change the drill bit, which is complicated to operate, affects the drilling process, reduces the efficiency and quality of drilling, and cannot meet the needs of production and use.
