Abstract
The utility model relates to a reciprocating lever mechanism of an oscillating scroll saw and a drag saw for fixing and clamping saw blades, which belongs to a main component of electric tools and is particularly suitable for widely using in the industry of woodwork decoration and families. The utility model is composed of a reciprocating lever with a knife carrying frame and an oscillating frame matched with the reciprocating lever, and the oscillating frame is a closed frame formed by connecting two draw rods with an upper and a lower sliding bearings. When the utility model is used, the motor rotates to drive a gear on the shaft, and an eccentric shaft of the gear is sheathed with a roller for causing the roller to glide in a guide track in the middle of the reciprocating lever. Therefore, the rotation of the motor is turned into up and down motion of the reciprocating lever to carry out cutting machining, and simultaneously, under the push of a force, the reciprocating frame of the reciprocating lever can oscillate forwards and backwards with small cylinders on both ends of the upper sliding bearing as a fulcrum.
Description
The utility model relates to a kind of main parts size of electric tool, and the swing type sweep-saw of be used for fixing, the clamping saw blade being used, the reciprocating lever mechanism of reciprocating saw are extensive use of in suitable especially carpenter's decoration industry and the family.
Its manufacture difficulty of employed reciprocating lever mechanism is big in the electric tool of existing external import, the cost height, and the price height, the assembly precision height is not suitable for being extensive use of.
The purpose of this utility model is to provide the reciprocating lever mechanism of a kind of swing type sweep-saw, reciprocating saw, its simple in structure, easy manufacturing, easy to assembly, use flexible, cheap.
The reciprocating lever mechanism that the utility model is achieved in that swing type sweep-saw, reciprocating saw cooperates institute to form by having the reciprocating lever of adorning knife rest with swing span, and swing span is the closed frame that is connected into upper and lower two sliding bearings respectively by two pull bars.
Accompanying drawing, structural representation of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Its centre of sliding bearing (2) has rectangular through-hole, both ends of the surface that one coaxial small column is respectively arranged.
Pull bar (3) has through hole for long bending flat bar on the both ends of the surface.
Reciprocating lever (1) has laterally on being, the flat rod of vertical mounting hole, and laterally mounting hole is guide rail (4).
The upper and lower end of reciprocating lever (1) inserts respectively in the intermediate throughholes of two ends sliding bearing (2), again two pull bars (3) are enclosed within respectively on the small column at two sliding bearings (2) two ends, for preventing the landing of pull bar (3), outside the pull bar (3) on properties of journal bearing lubricated (2) both sides, use jump ring (5) to block again, connect into the swing span of closed frame formula.Be with the malthoid (6) and the retaining felt plate (7) of dustproof effect in the lower end of reciprocating lever (1), be screwed dress knife rest (8) on the end, reciprocating lever mechanism is assembled into.
During use, this mechanism utilizes the small column on the sliding bearing to be positioned on the casing of sweep-saw, reciprocating saw, gear on the motor rotating band moving axis, one eccentric shaft is arranged on the gear, be with a roller on the axle, roller slides in the guide rail (4) in the middle of the reciprocating lever (1), the rotation of motor is transformed into the upper and lower motion of reciprocating lever (1), thereby carries out sawing work.The small column at reciprocating lever swing span energy above sliding bearing (2) two ends is a fulcrum under the promotion of a power simultaneously, swing.
The utility model is compared with prior art: because the reciprocating lever mechanism of this swing type sweep-saw, reciprocating saw adopts In the closed frame that is connected into upper and lower two sliding bearings respectively by two pull bars, do back and forth and pendulum with reciprocating lever The structure of moving motion, its simple in structure, easy manufacturing, flexible, low cost of manufacture easy to assembly are therefore suitable Use in the big electric tool in batches.
Claims (2)
1, the reciprocating lever mechanism of a kind of swing type sweep-saw, reciprocating saw, by the reciprocating lever (1) that has dress knife rest (8) cooperate with swing span form, it is characterized in that swing span is the closed frame that two pull bars (3) connect into upper and lower two sliding bearings (2) respectively.
2, reciprocating lever according to claim 1 mechanism is characterized in that sliding bearing (2) has rectangular through-hole, both ends of the surface that one coaxial small column is respectively arranged in the middle of it; Pull bar (3) has through hole for long bending flat bar on the both ends of the surface; The upper and lower end of reciprocating lever (1) inserts respectively in two ends sliding bearing (2) intermediate throughholes, and two pull bars (3) are enclosed within respectively on the small column at two sliding bearings (2) two ends, and blocks at pull bar (3) the external application jump ring (5) on properties of journal bearing lubricated (2) both sides.
