Description
Technical field
The utility model relates to a kind of rig, specifically a kind of hand electric rig.
Background technology
Compared with mechanical powered rig, hand-held electric drill facility have good speed adjustment features, and reliability is strong, operate safer, convenient, flexible, be easy to realize a series of superiority such as automatic control.But in hand-held drill use procedure, in rig, in reciprocating member and rig, the repeated impact between some parts has produced huge vibration, and this great vibrations is delivered in operator's hand by the handle of rig.For operator, this is inconvenient, unsafe especially.
Utility model content
The problem existing for above-mentioned prior art, the utility model provides a kind of electric drilling machine, effectively reduces the vibration bringing while use, improves its security.
To achieve these goals, a kind of hand electric rig of the present utility model, this rig comprises the tool holding body of housing and housing front portion, on described tool holding body, drill bit is installed, in described housing, motor is set, gear-box, hollow main shaft, pressure actuated device and thrust unit, described housing rear portion arranges handle, described gear-box is connected with electric electromechanics, described gear-box drives the piston of hollow main shaft to move forward and backward, the front portion of described hollow main shaft arranges pressure actuated device, the front portion of described pressure actuated device arranges thrust unit, shock reducing structure is also set in described housing, described shock reducing structure by spring element be connected to housing before, rear portion,
Further, housing top arranges heat abstractor.
Preferably, spring element is disc spring.
Preferably, shock reducing structure is cylinder.
Preferably, cylinder is steel matter or brass material cylinder.
This hand electric rig in use, motor driven gear case rotates, gear-box drives again hollow main shaft inner carrier to seesaw, moving forward and backward of piston started pressure actuated device, this pressure actuated device is applied to different pressures on thrust unit, this thrust unit make on tool holding body drill bit also forward, rotate backward, in housing the motion of all parts and drill bit forward, rotating backward has all produced huge vibration, when this vibration is passed through on shock reducing structure driving handle, vibration weakens significantly, has improved the security using.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1, pressure actuated device, 2, housing, 3, motor, 4, shock reducing structure, 5, trigger switch, 6, handle, 7, drill bit, 8, tool holding body, 9, thrust unit, 10, piston, 11, gear-box, 12, spring element, 13, hollow main shaft.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment mono-
As shown in Figure 1, a kind of hand electric rig of the present utility model, this rig comprises the tool holding body 8 of housing 2 and housing 2 front portions, drill bit 7 is installed on tool holding body 8, the interior motor 3 that arranges of housing 2, gear-box 11, hollow main shaft 13, pressure actuated device 1 and thrust unit 9, described housing 2 rear portions arrange handle 6, gear-box 11 is electrically connected with motor 3, gear-box 11 drives the piston of hollow main shaft 13 to move forward and backward, the front portion of hollow main shaft 13 arranges pressure actuated device 1, the front portion of pressure actuated device 1 arranges thrust unit 9, shock reducing structure 4 is also set in housing 2, shock reducing structure 4 by spring element 12 be connected to housing 2 before, rear portion.
Operation principle: this hand electric rig in use, motor driven gear case rotates, gear-box drives again hollow main shaft inner carrier to seesaw, moving forward and backward of piston started pressure actuated device, this pressure actuated device is applied to different pressures on thrust unit, this thrust unit make on tool holding body drill bit also forward, rotate backward, in housing the motion of all parts and drill bit forward, rotating backward has all produced huge vibration, when this vibration is passed through on shock reducing structure driving handle, vibration weakens significantly, has improved the security using.
Embodiment bis-
On the basis of embodiment mono-, these housing 2 tops arrange heat abstractor.In use, power is large, the time is long, shell space is little, can produce a large amount of heats for this hand electric rig, and this heat accumulation gets up and can have a strong impact on the work of rig, adds a heat abstractor, and the heat producing during by use is discharged in time.
This hand electric rig medi-spring element 12 is disc spring, is connected with the forward and backward of housing 2 by disc spring, and the damping effect of disc spring is better than general spring.
Embodiment tri-
Identical with the structure of embodiment bis-, just this shock reducing structure 4 is cylinder, because cylindrical external surface area is larger, the contact area that damping is passed through is also large, and what damping effect and the cylindrical effect of other shape will be good is many.
In above-mentioned three embodiment, preferably shock reducing structure 4 is steel matter or brass material cylinder, known by experiment, and the cylindrical damping coefficient of this steel or brass material is large, and damping effect is all right.
