[detailed description of the invention]
A kind of reciprocating electric tool involved by the specific embodiment of the present invention as shown in Figure 1 to Figure 3, this reciprocating electric tool 100 includes has rear and front end along the housing 1 of longitudinally extension, the definition of this housing 1, as in figure 2 it is shown, left side is front end, right side is rear end.It is arranged on the drive mechanism 2 in housing 1, it is connected to the handle apparatus 3 of housing 1 rear end, equally longitudinally is provided with motor 4 in the rear end of housing 1, it is perpendicular to longitudinally in the front end of housing 1 and is provided with main shaft 9, main shaft 9 is fixedly connected with gear 5, this gear 5 and motor gear 10 engaged transmission, thus the rotation torque of motor 4 is transferred on main shaft 9, an eccentric block 5b it is formed with on the top of gear 5, it is arranged on gear 5 and is parallel to the eccentric shaft 5a of main shaft 9, the reciprocating lever 6 being connected on eccentric shaft 5a and move reciprocatingly along longitudinally, it is arranged in handle apparatus 3 and is parallel to the flexible member 7 that main shaft 9 is arranged, it is arranged on the damping element 8 between housing 1 and handle apparatus 3.
Refer to shown in Fig. 1 to Fig. 2, the rear end of described housing 1 is provided with the convex extension part 11 protruded in handle apparatus 3, described convex extension part 11 is provided with clamping part 11a along longitudinally both sides, described clamping part 11a comprises through hole 1a, described through hole 1a ovalize structure, described handle apparatus 3 is provided with the holding part 31 matched with clamping part 11a, described holding part 31 comprises bearing pin 3a, during assembling, bearing pin 3a can make clamping part 11a and holding part 31 link together along longitudinally activeness through through hole 1a, and there is a certain amount of gap between coordinating, with handle apparatus 3, there is along longitudinally skew activity space realizing housing 1, it is provided with flexible member 7 between described housing 1 rear end and handle apparatus 3, the both sides up and down of described flexible member 7 are connected in described handle apparatus 3, centre is connected to the rear side of described housing 1.
Refer to shown in Fig. 2, it is additionally provided with damping element 8 between described housing 1 and handle apparatus 3, this damping element 8 can be made by having certain elastic quality of rubber materials, described damping element 8 rounds distribution by linking together that housing 1 and handle apparatus 3 seal along the circumferencial direction of housing 1, and the elastic deformation of damping element 8 can absorb the part vibration produced in reciprocating sow motor process.
Refer to shown in Fig. 3, described drive mechanism 2 includes the motor 4 being arranged in housing, the main shaft 9 of rotation is driven by motor 4, peace turns the gear 5 on main shaft 9, it is arranged on the eccentric shaft 5a on gear 5 and the reciprocating lever 6 being connected on eccentric shaft 5a and moving reciprocatingly along longitudinally, the top of described gear 5 is formed with eccentric block 5b, and this eccentric block 5b and eccentric shaft 5a is that 180 degree of phase places are arranged, so that eccentric shaft 5a connects in bias relative to main shaft 9.
The technical scheme of elimination reciprocating sow of the present invention vibration is: refer to shown in Fig. 1 to Fig. 2, the rotary power drive shaft 9 of motor 4 rotates, main shaft 9 is fixedly connected with gear 5, an eccentric block 5b it is formed with on the top of gear 5, it is arranged on gear 5 and is parallel to the eccentric shaft 5a of main shaft 9, this eccentric shaft 5a to be flexibly connected with the groove 6a along the reciprocating lever 6 of longitudinally setting in housing 1.Thus, when main shaft 9 rotates, eccentric shaft 5a will do eccentric rotary along with the rotation of main shaft 9, and drive reciprocating lever 6 to do linear reciprocating motion along longitudinally further, the saw blade 12 being arranged on reciprocating lever 6 is made to carry out reciprocating cutting action, now, owing to reciprocating lever 6 quickly reciprocating motion can bring bigger vibration to machine, vibration can form thrust to the right, housing 1 is made to extrude towards the direction of handle apparatus 3, because there is a certain amount of gap in coordinating between bearing pin 3a with through hole 1a, so housing 1 can offset to the right extruding flexible member 7 by opposite handle device 3, now flexible member 7 produces elastic deformation to absorb the housing 1 thrust to handle apparatus 3, the elastic damping element 8 being simultaneously located between housing 1 and handle apparatus 3 produces elastic deformation can also absorb the vibration of a part.
Above-mentioned flexible member is adopted can effectively to absorb, as damper mechanism, the vibration that reciprocating lever brings in motor process, thus eliminating the feeling of fatigue that user produces in operation machine processes.
