Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a sub-jaw saw head. Background Art

[0002] Traditional wooden furniture is cut with an electric circular saw, which is prone to edge chipping when sawing wood boards, affecting the appearance. The double saw uses a double saw blade for sawing, in which the sub-saw is responsible for shallow cutting and marking, and the main saw is responsible for cutting. This can effectively solve the problem of edge chipping. The double saw will generate a large amount of cutting dust during operation. In order to prevent the cutting dust from floating in the operating environment and affecting the operator's work and health, the double saw head is currently equipped with a dust cover on the front side of the double saw. Most of the current dust covers are fastened with several bolts. Since the dust cover needs to be disassembled and cleaned frequently, the disassembly and assembly of the dust cover requires the cooperation of multiple operators, and the disassembly and assembly time is long, which affects the efficiency of the double saw. Utility Model Content

[0003] The utility model provides a sub-head saw head to solve the problem in the prior art that the dust collecting cover cannot be quickly disassembled and assembled, which affects the efficiency of the equipment.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A sub-saw head includes a machine table, a large saw, a small saw, a dust hood and an electric controller. The large saw is fixedly mounted on a fixed plate, and the small saw is movably mounted on the fixed plate. The fixed plate is connected to the machine table via a rotating shaft on the top. Arc grooves are symmetrically provided on both sides of the machine table. Each arc groove is connected to the fixed plate via a rotating handle. The bottom of the dust hood is connected to the fixed plate via a number of spring brackets. The lower part of the dust hood is connected to the fixed plate via a number of fastening bolts. Magnet suction pieces are provided on the fixed plate corresponding to the positions of the fastening bolts. A push-pull cover is provided on the side of the dust hood. The card slot of the push-pull cover can be snapped onto the card column on the dust hood. The push-pull cover is connected to the push-pull handle.

[0006] The arc grooves on both sides of the above machine are 45° arc grooves.

[0007] When the utility model is working, the angles of the large saw and the small saw are adjusted according to the different thicknesses of the plates by rotating the handle to drive the fixing plate along the arc groove and the rotating shaft. The powder chips generated during the cutting process will be concentrated in the dust collecting cover on the front side. When it needs to be disassembled and cleaned, the operator only needs to unscrew the fastening bolts at the bottom and separate the sliding cover from the clamping column by pushing and pulling the handle to remove the dust collecting cover. When installing, the operator brings the dust collecting cover close to the fixing plate. Under the suction force of the magnetic suction piece, the position of the fastening bolts can be quickly located, the fastening bolts can be screwed on, and then the sliding cover can be clamped on the clamping column by pushing and pulling the handle, so that the dust collecting cover can be quickly installed.

[0008] The utility model realizes the rapid disassembly and assembly of the dust collecting cover of the mother-and-child saw head, reduces the disassembly and assembly time of the dust collecting cover, effectively improves the use efficiency of the mother-and-child saw equipment, and has the advantages of convenient disassembly and assembly, small space occupation, and environmental protection and high efficiency.
