Abstract
The utility model discloses a but hacksawing machine of quick return to improve equipment work efficiency. Which comprises a frame, be equipped with drive arrangement in the frame, drive arrangement is including rotating the motor, the gear, decide rack and carry -over bar, the hookup has rotatable crank on the output shaft of rotation motor, the articulate driven end passes through the connecting rod hookup in the axis of rotation of gear, the both ends of connecting rod are articulated with the axis of rotation of crank and gear respectively, the gear simultaneously with decide the rack and move rack toothing, it fixes in the frame to decide the rack, carry -over bar straight line slide the hookup in the frame and with the output rod coupling, the axis of rotation of gear removes orbit place straight line and leaves mutually with articulate pivot axis. Sufficient dynamics has been guaranteed to the bow saw when the cutting to return and to move back rapidly, improved the work efficiency of hacksawing machine.
Description
Technical field
The utility model relates to a kind of hacksawing machine.
Background technology
Saw bow hacksawing machine being equipped with saw blade is reciprocating, and with the mode feeding of saw frame around a spot wobble, machine tool structure is simple, and volume is little, but efficiency is lower.The movement locus of hacksawing machine saw blade has straight line and camber line two kinds.During movement in a curve, saw bow is around spot wobble one low-angle, and the approach of each sawtooth is comparatively large, and chip removal is easy, and efficiency is higher, and new-type hacksawing machine is adopted in this way mostly.
Current known sawing device has hacksawing machine, garden sawing machine, band sawing machine three kinds.Such lathe is because of the advantage face extensive use of its " equipment is simple, easy to operate and have certain precision ".The saw blade of bow saw is stripe shape, pulls processing work back and forth during work, and band saw is annular, and during work, circulation pulls processing work.So band sawing efficiency is high, the loss of saw blade is also higher, although bow saw efficiency is low, consumptive material loss is also lower.
Driving mechanism on hacksawing machine drives bow saw to move back and forth, and cuts when bow saw advances to material, and when bow saw proceeds to the end, cutting action completes, and bow saw starts with same speed rollback, and in the process of rollback, bow saw no longer cuts material.The operating efficiency of whole equipment has to be hoisted.
Utility model content
The utility model be intended to provide a kind of can the hacksawing machine of quick return, to improve equipment operating efficiency.
In this programme can the hacksawing machine of quick return, comprise frame, frame is provided with drive unit, drive unit comprises rotary electric machine, gear, fixed rack and carry-over bar, the output shaft of rotary electric machine is connected with rotating crank, the driven end of crank is connected on the turning cylinder of gear by connecting rod, the two ends of connecting rod are hinged with the turning cylinder of crank and gear respectively, gear engages with fixed rack and carry-over bar simultaneously, fixed rack is fixed in frame, carry-over bar linear slide to be connected in frame and to connect with take-off lever, the turning cylinder motion track place straight line of gear and the center of rotation of crank from.
Rotary electric machine drives crank to rotate around it the lasting rotation in axle center, and crank is by connecting rod driven gear reciprocating rolling on fixed rack, and the turning cylinder motion track of gear is straight line.While gear reciprocating rolls, its engagement drives carry-over bar linear reciprocation in frame to move, and the now movement and rolling of gear acts on carry-over bar simultaneously, and its translational speed relative to gear is accelerated back and forth.And, due to the turning cylinder motion track place straight line of gear and the center of rotation of crank from, can realize crank drives carry-over bar and take-off lever to drive bow saw to implement cutting action more than 180 °, then crank can complete the rotation of whole circle less than 180 °, also achieves the fallback action after bow saw cutting in this process.Urgency after above-mentioned action back and forth then achieves mechanism's cutting is returned.Bow saw ensure that enough dynamics when cutting, and rollback is rapid, improves the operating efficiency of hacksawing machine.
Further, the turning cylinder of crank is positioned on the straight line of fixed rack length direction place.
Further, the guide rod on carry-over bar is slidably connected in the pilot hole in frame.
Further, take-off lever is provided with bow saw seat.For the bow saw that is fixedly connected.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: crank 1, connecting rod 2, gear 3, carry-over bar 4, fixed rack 5, frame 6.
The improvement of this device is only its part-structure, i.e. the part of the application's record.Other functional parts can refer to prior art to carry out arranging enforcement, and the present embodiment does not make improvements other functional parts, and other functional parts do not improved in device are not shown in the drawings.Hacksawing machine frame is provided with drive unit, embodiment is substantially as shown in Figure 1: drive unit comprises rotary electric machine, crank, connecting rod, gear, fixed rack and carry-over bar, the output shaft of rotary electric machine is perpendicular to drawing place plane, so not shown in the drawings, the output shaft of rotary electric machine is connected with rotating crank, and crank rotates in drawing plane.The drive end of the driven end articulated linkage of crank, the driven end of connecting rod is hinged on the turning cylinder of gear.
Engage with the fixed rack of its upper and lower and carry-over bar while of gear, fixed rack and carry-over bar all keep level.The fixed rack of below is fixed in frame, and carry-over bar relies on the guide rod linear slide at its two ends to be connected in the pilot hole in frame, and connects with take-off lever, and take-off lever is provided with bow saw seat, and this part-structure is not shown.
Rotary electric machine drives crank to rotate around it the lasting rotation in axle center, and crank is by connecting rod driven gear reciprocating rolling on fixed rack, and the turning cylinder motion track of gear is straight line.The turning cylinder of crank is positioned on the straight line of fixed rack length direction place.
While gear reciprocating rolls, its engagement drives carry-over bar linear reciprocation in frame to move, and the now movement and rolling of gear acts on carry-over bar simultaneously, and its translational speed relative to gear is accelerated back and forth.And, due to the turning cylinder motion track place straight line of gear and the center of rotation of crank from, can realize crank drives carry-over bar and take-off lever to drive bow saw to implement cutting action more than 180 °, then crank can complete the rotation of whole circle less than 180 °, also achieves the fallback action after bow saw cutting in this process.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
