Abstract
Provided is a workpiece cutting device. A crank is used as an active member, and carries out a gyratory movement. The crank, a connection rod, and a saw bow support are connected with each other through hinges in sequence, and a saw blade is fixed on a saw bow. One end of an upper beam is hinged on a sawing machine support through an articulated shaft, and the other end of the upper beam is hinged with the saw bow through an articulated shaft. A plan crank rocker mechanism is formed by the upper beam, the saw bow support, the connection rod, the crank, and the machine support. When the crank carries out the gyratory movement, the saw bow support and the saw blade are driven to swing around a hinge point by the connection rod, so that the saw blade can move back and forth on a workpiece. Since the saw bow support wings around the hinge point, the angle of the saw blade to the workpiece is continuously changing, so that the saw blade can cut on the workpiece along a camber line, and make a point contact with the workpiece.
Description
Affiliated technical field
The utility model relates to a kind of work piece cut device, especially a kind of cutter sweep that is applicable to the hacksawing machine employing.
Background technology
At present, the work piece cut device that China's hacksawing machine adopts is all to adopt ram type straight cuts mode, saw blade along with ram along the slideway linear reciprocating motion, sawtooth is to contact along straight line with workpiece, the diameter of cutting is larger, and contact-making surface is longer, and pressure is less, cutting speed is slower, and production efficiency is low; And ram slideway production and processing required precision is higher, thereby cost is higher.
Summary of the invention
In order to overcome the problem of existing work piece cut device, the utility model provides a kind of articulated type work piece cut device, and the saw blade of this device can be along the camber line cut workpiece, and saw blade becomes point to contact with workpiece.
The utility model solves the technical scheme that its technical problem adopts: crank is driving link, carrying out circumference rotatablely moves, crank, connecting rod, saw bow order are hinged by hinge separately, saw blade is fixed on saw bow, upper beam one end is hinged by hinge and sawing machine frame, and the other end is hinged by hinge and saw bow.Upper beam, saw bow rack, connecting rod, crank, frame form Planar Crank-and-rocker Mechanism together.When crank is done gyration, drive saw bow rack and saw blade swings around pin joint by connecting rod, saw blade moves back and forth on workpiece; Because saw bow rack swings back and forth around pin joint, thus saw blade with respect to workpiece, angle is constantly to change, and on workpiece, along the arc line shaped sawing, so saw blade becomes to put with workpiece, contacts.
The beneficial effects of the utility model are, by saw bow, around pin joint, swing, and realize the continuous variation of saw blade angle, thereby realize along the camber line cut workpiece.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the structural map of an embodiment of the utility model.
In figure, 1. upper beam, 2. damping oil cylinder, 3. crank, 4. connecting rod, 5. saw bow, 6. saw blade, 7. fixture, 8. workpiece, 9. frame.
The specific embodiment
In Fig. 1, crank (3) is the force piece of this device, around the O point, rotate, crank (3) is point articulated by A with connecting rod (4), the other end of connecting rod (4) is hinged by pin joint C and saw bow (5), one end of upper beam (1) is hinged by jointed shaft B and frame (9), and the other end is hinged by jointed shaft D and saw bow (5).Upper beam BD, saw bow DC, connecting rod CA, crank OA form Planar Crank-and-rocker Mechanism together with frame BO; Workpiece (8) is fixing by fixture (7), when crank (3) when the O point rotates, by connecting rod (4) drive saw bow (5) and saw blade (6), at workpiece (8), above move back and forth, because saw bow (5) and upper beam (1) are hinged in the D point, so saw bow (5) and saw blade (6) can only swing around pin joint D, so saw blade (6) is constantly to change with the angle of workpiece (8), saw blade (6) is pressed certain radian around workpiece (8) sawing, thereby realizes along the camber line cut workpiece.
In the embodiment shown in Figure 2, upper beam (1) is hinged on frame (9) by jointed shaft B, saw bow (5) is articulated on upper beam (1) by jointed shaft D, crank (3) is the force piece of this device, around the O point, rotate, crank (3) is point articulated by A with connecting rod (4), the other end of connecting rod (4) is hinged by pin joint C and saw bow (5), it is upper that one end of damping oil cylinder (2) is hinged on frame (9), and the other end is hinged on upper beam (1).
Claims (3)
1. a work piece cut device, crank is driving link, carries out circumference and rotatablely moves, crank, connecting rod, saw bow order are hinged by hinge separately, saw blade is fixed on saw bow, it is characterized in that: upper beam one end is hinged by hinge and sawing machine frame, and the other end is hinged by hinge and saw bow.
2. work piece cut device according to claim 1, it is characterized in that: upper beam one end is hinged by jointed shaft and sawing machine frame, and the other end is hinged by jointed shaft and saw bow.
3. work piece cut device according to claim 1 and 2, it is characterized in that: be combined with damping oil cylinder between frame and upper beam, damping oil cylinder one end and frame are hinged, and the other end and upper beam are hinged.
