Embodiment Construction
[0016] The present invention will be described in further detail below by means of specific embodiments:
[0017] The reference signs in the drawings of the description include: reciprocating cylinder 1, rack 2, drive shaft 3, grinding piece 4, through hole 5, driven gear 6, bearing 7, cutting tool 8, transmission cylinder 9, control slider 10 .
[0018] The embodiment is basically as attached figure 1 Shown: as figure 1 As shown, the cutter unit includes a transmission shaft 3 and a positioning mechanism installed on the frame. A bearing 7 is sleeved in the middle of the transmission shaft 3, and a fixed block is integrally installed on the bearing 7, and the fixed block is fixed on the frame. The right end of transmission shaft 3 is detachably connected with two cutting knives 8, and the two cutting knives 8 are perpendicular to each other, and the left end of transmission shaft 3 is coaxially connected with driven gear 6; The hole 5 and the two through holes 5 are locate...

The invention relates to a cutter replacing method. Two cutting tools of a right-angle structure are installed on a transmission shaft, cutting blades of the two cutting tools face the same direction, the transmission shaft is sleeved with a bearing, the bearing is fixed to a machine frame, and the end, away from the cutting tools, of the transmission shaft is sleeved with a driven gear; an output shaft of a reciprocating air cylinder is provided with a rack, the length of the rack is one quarter of the perimeter of the driven gear, the tooth number of the rack is the same as one quarter of the tooth number of the gear, and the driven gear is meshed to the starting end of the rack; an output shaft of a transmission air cylinder is perpendicularly provided with two grinding pieces; a control sliding block is slidably connected between a point contact switch and each cutting tool; and when the cutting tools finish cutting a workpiece, the rack is pulled by starting the reciprocating air cylinder, the rack drives the driven gear to rotate by 90 degrees, and the point contact switch controls the transmission air cylinder to drive the two grinding pieces to grind the cutting tools to be ground. By the implementation of the method, the problem that in the prior art, cutting tools need halt protection and replacement is solved.
Description
technical field [0001] The invention relates to the field of machining, in particular to a tool replacement method. Background technique [0002] The workpiece needs to be cut during the processing process. For example, if the continuously output workpiece is cut on the production line, the transmission time interval between the two workpieces is usually about 10s. If it becomes not sharp or deformed, it will cause the problem of uneven incision and slow cutting speed when cutting the workpiece; in addition, the tool replacement time is long, usually takes about 5 minutes, so it is necessary to turn off the equipment and the entire production line to replace, Thereby the output of the workpiece is reduced. In addition, because the temperature requirement of the workpiece is higher during cutting, once the product cools down, it is not conducive to cutting. Contents of the invention [0003] The present invention intends to provide a cutting tool replacement method to solv...
