The specific embodiment
Further specify the present invention below in conjunction with Figure of description.
As shown in the figure; A kind of pneumoelectric type power head device comprises interconnective body 7, housing 22 and belt transmission case 28; Run through in the inner chamber of body 7 and housing 22 power transmission shaft 19 is set; Power transmission shaft 19 rear ends are connected with motor 29 through the transmission mechanism that is arranged in the belt transmission case 28, and motor 29 is fixed on the belt transmission case 28, the drill chuck 1 that power transmission shaft 19 front ends are in transmission connection and are used for fixing cutter.Under the effect of motor 29, drive power transmission shaft 19 rotations, thereby make the cutter that is installed on the drill chuck 1 be rotated like this.Transmission mechanism in the belt transmission case 28 mainly comprises driven pulley 24, belt 25, tension pulley 26 and driving wheel 27; Driven pulley 24 is connected with power transmission shaft 19; Driving wheel 27 is connected with motor 29; Driven pulley 24 is connected through belt 25 with driving wheel 27, in order to prevent to skid, tension pulley 26 is set on the belt 25.In order to be beneficial to transmission and power transmission shaft 19 to be supported in the housing 22, bearing 23 is set in power transmission shaft 19 rear ends.
Drill chuck 1 can be accomplished elastic motion among the present invention, specifically accomplishes through following structure:
In order to make main shaft 20, collar bush 11 and center-pole 12 etc. constitute whole elastic motion in body 7, need a power source, this power source is compressed air.Therefore in the front and back side of center-pole 12 heads the back annular seal space 13 that forms between the preceding annular seal space 8 that supplies pneumatically operated annular seal space, sealing chamber to comprise to form between body 7, collar bush 11 and the center-pole 12 and body 7, housing 22 and the center-pole 12 is set respectively.The compressed air that feeds through the external world acts on preceding annular seal space 8 and back annular seal space 13, and it is elastic to promote center-pole 12, thereby makes that drill chuck 1 is elastic.
The present invention all can be provided with sealing ring and spacer ring in order to obtain the air-tightness of body 7 inner chambers in the junction of each parts.As body cone spacer 9 being set, main shaft spacer ring 17 or the like is set at main shaft 20 front ends at body 7 inwalls.Between housing 22 and the center-pole 12 buffer gasket 14 is set also, prevents that center-pole 12 and housing 22 from clashing and destroy parts.
The present invention is provided with guide post 35 in order accurately to control the elastic stroke of drill chuck 1 in housing 22, guide post 35 through the screw bracket 34 that is provided with stretch into housing 22 interior center-poles 12 and be connected.Screw bracket 34 upper ends and guide post 35 are slidingly matched, and the lower end is fixedly connected center-pole 12.Simultaneously, also on housing 22, fixedly install block bar 32, one group of block 33 is set on the block bar 32, block 33 is provided with limit switch, can control the motion of screw bracket 34 automatically.Screw bracket 34 is used for protection with the guide post 35 outer protective covers 31 that are provided with.
The present invention fixedly installs damper 30 in order accurately to control the elastic schedule speed of drill chuck 1 on body 7, the expansion link of damper 30 matches with screw bracket 34.When screw bracket 34 in when motion, control rate effectively, thus accurately control the schedule speed of drill chuck 1.
Pneumoelectric type power head device of the present invention can be accomplished drill chuck 1 rotation and elastic motion.When rotatablely moving: motor 29 rotates, and under the effect of transmission mechanism, drives power transmission shaft 19 rotations, drives main shaft 20 rotations, thereby makes drill chuck 1 rotation.During elastic motion, through compressed-air actuated adjusting in preceding annular seal space 8 and the back annular seal space 13, it is elastic in body 7 to promote center-pole 12, and center-pole 12 pulling main shafts 20 move with it with collar bush 11, thereby make that drill chuck 1 is elastic; And front and back are when protracting, and screw bracket 34 matches with damper 30, thus the control schedule speed.
Shown in the above and the figure only is preferred implementation of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the principle of the invention, can also make some modification and improvement, these also should be regarded as belonging to protection scope of the present invention.
