The specific embodiment
Fig. 1 is to shown in Figure 13, specific embodiments for a kind of single button four function electric hammers of the utility model, it comprises body, cylinder assembly 1, block stamp 25, pneumatic hammer 24, big spring 2, big spring back-up ring 3, clutch base 4, auger tooth 7, piston component 8, eccentric shaft 9, eccentric shaft spring 10, eccentric shaft clutch 11, eccentric shaft plectrum 12, one-level gear 13, motor 15, conelet tooth 16, locking plate 18, locking plate spring 17, conelet tooth spring 19, conelet tooth-like clutch 21, secondary gear 23, knob 27, described knob 27 is provided with toggle pin 28, between eccentric shaft clutch 11 and one-level gear 13, be provided with eccentric shaft plectrum 12, between conelet tooth-like clutch 21 and secondary gear 23, be provided with conelet tooth plectrum 22, body is provided with knob plectrum 14 moving up and down, knob plectrum 14 is provided with shift fork, toggle pin 28 is connected on the knob plectrum 14, eccentric shaft plectrum 12 is arranged on the shift fork top of knob plectrum 14, and conelet tooth plectrum 22 is arranged on the shift fork below of knob plectrum 14.Described knob 27 is provided with button spring 29 and button 26, body is provided with and four kinds of draw-in grooves that POF is corresponding, button 26 is provided with the latch that cooperates with draw-in groove, latch is inserted in the draw-in groove, knob 27 can not rotated automatically, during translation function when using a kind of function, will be with button 26 by advancing knob 27, make the latch of button 26 break away from draw-in groove, ability turning knob 27 is realized the function conversion.Described clutch base 4 is provided with corresponding four half slots with auger tooth 7, be provided with cylindrical roller 6 in the groove, big spring 2 is positioned on the cylinder assembly 1 through big spring back-up ring 3, axle-steel silk back-up ring 30, and clutch base 4 usefulness keys 5 are connected with cylinder assembly 1, axially can move freely, as shown in Figure 5; The output bit load is excessive in that the hammer drill merit is single when boring operation when electric hammer, under the state that motor does not stop, auger tooth 7 rotates and promotes cylindrical roller 6, cylindrical roller 6 is deviate from from the half slot of auger tooth 7, clutch base 4 and auger tooth 7 are skidded, revolving force can not be delivered to cylinder assembly 1, thereby reach overload protection effect; Behind load reduction, electric hammer recovers operate as normal again.
Further sketch the operation principle that the utility model is realized four kinds of functions below in conjunction with accompanying drawing.
Structure and knob position schematic diagram when Figure 1 shows that the utility model hammer drill function, during work, the output gear shaft of motor 15 drives one-level gear 13 and secondary gear 23 rotates, one-level gear 13, eccentric clutch 11, key 20 under 10 effects of eccentric shaft spring fuse with eccentric shaft 9, and transmission rotatory force, drive piston component 8 and move back and forth generation pressure, promote pneumatic hammer 24 bump block stamps 25, thereby finish the transmission of impact energy.Secondary gear 23 fuses with conelet tooth 16 by conelet tooth-like clutch 21, key 20, and transmission rotatory force, conelet tooth 16 drives auger tooth 7 and rotates, auger tooth 7 fuses with cylinder assembly 1 by cylindrical roller 6, clutch base 4, key 5, and transmission rotatory force, thereby finish the revolving force transmission, realize electric hammer hammer drill function.
Figure 2 shows that structure and knob position schematic diagram when the utility model list bores function.Turning knob 27, knob 27 moves up knob plectrum 14 by toggle pin 28, drives eccentric shaft plectrum 12 and moves upward, and eccentric shaft clutch 11 is upwards dialled, and eccentric shaft clutch 11 is broken away from combine with one-level gear 13.During work, the output gear shaft of motor 15 drives one-level gear 13 and secondary gear 23 rotates, and one-level gear 13 does not transmit rotatory force because of breaking away from eccentric shaft clutch 11, can not drive piston component 8 and move back and forth the generation impact energy; Secondary gear 23, conelet tooth-like clutch 21, key 20 fuse with conelet tooth 16 under conelet tooth spring 19 effect, and transmission rotatory force, conelet tooth 16 drives auger tooth 7 and rotates, auger tooth 7 is connected as a single entity with cylinder assembly by cylindrical roller 6, clutch base 4, key 5, and transmission rotatory force, thereby finish the transmission of revolving force, realize that the electric hammer list bores function.
Figure 3 shows that structure and knob position schematic diagram when the utility model list clavicorn degree is adjusted function.Under the situation of shutting down; knob 27 is transferred to position as shown in the figure; knob 27 moves down knob plectrum 14 by toggle pin 28; driving conelet tooth plectrum moves downward; conelet tooth-like clutch 21 is set aside, conelet tooth-like clutch 21 had both been broken away from and the combining of secondary gear 23, again not with the geared neutral state of locking plate 18 interlocks; conelet tooth 16 is free to rotate, thereby can regulate the angle of chisel by rotary drill bit.
Structure and knob position schematic diagram when Figure 4 shows that the utility model list hammer function.Turning knob 27, knob 27 moves down knob plectrum 14 by toggle pin 28, drive conelet tooth plectrum 22 and move downward, with conelet tooth-like clutch 21 to setting aside, conelet tooth-like clutch 21 break away from secondary gear 23 combine and enter locking plate 18; During work, the output gear shaft of motor 15 drives one-level gear 13 and secondary gear 23 rotates, and because of conelet tooth-like clutch 21 and secondary gear 23 are in disengaged position, does not transmit rotatory force, can not drive conelet tooth 16 and rotate the generation rotation; One-level gear 13, eccentric shaft clutch 11, key 20 under 10 effects of eccentric shaft spring fuse with eccentric shaft 9, and transmission rotatory force, drive piston component 8 reciprocating motions and produce living pressure, promote the transmission that pneumatic hammer 24 bump block stamps 25 are finished impact energy, thus the single function of hammering into shape of realization.When electric hammer was in single hammer state, conelet tooth-like clutch 21 placed locking plate 18, as shown in Figure 7, can prevent that drill bit rotates when single hammer operation.When conelet tooth-like clutch 21 does not align locking plate 18 when setting aside fully, locking plate 18 by locking plate spring 17 to pressing down, loom starts, when secondary gear 23 rotates, conelet tooth-like clutch 21 aligns locking plate 18 flute profiles after turning over certain angle, under the effect of locking plate spring 17, enter fully in locking plate 18 flute profiles, thereby reach the purpose of stop.
