Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
A kind of Ball type torsion clutch type electric tool, as Fig. 1, Fig. 2, Fig. 3, with Fig. 4 a, shown in 5a, comprise the hand-held housing 1 of electric tool, and the speed changer 3 to be connected successively with the drive motors 2 be arranged in hand-held housing 1, adapter flange 4, described adapter flange 4 connects the transmission clutch ring 6 that a plum blossom hole inner ring 27 is equipped with steel ball 5, through bearing 7, the turning cylinder 9 that a termination is provided with quick-release dop 8 is installed during adapter flange 4 and transmission clutch ring 6 enclose, as Fig. 5 a, shown in 5b, in the shaft flange end face that turning cylinder 9 is provided with groove 10, setting pressure block 11 successively, compression spring 12, the stage casing of adjustment screw thread 13 and gathering sill 14 is provided with in turning cylinder 9, the adjusting nut 15 that an end face is provided with umbrella tooth is housed, and the push block 16 that adjusting nut 15 right-hand member Step Shaft is set with, in the deferent segment of turning cylinder 8, hand-held housing 1 front port is fixed on through bearing 7 and bearing block 17.
As shown in Fig. 1 and Fig. 6 a, 6b, the window 19 inserting adjustment key 18 is had above the hand-held housing 1 of the present invention, the transparent scale 20 being carved with moment of torsion dynamics is housed on one side in window 19, described push block 16 cylindrical is equipped with guide pin 21 and lock-screw 22 respectively, and be carved with mpving wire 23, push block 16 is also provided with adjustment key socket 24, described pressure block 11 front end, in hand-held housing 1 built with a proximity transducer 25.
When Ball type torsion clutch type electric tool of the present invention uses, the requirement of torque magnitude first will be locked according to locking screw, push the scuttle 28 at hand-held housing 1 top window 19 place open, adjustment key 18 is inserted window 19, engage with adjusting nut 15 end face umbrella tooth, adjusting nut 15 is driven to rotate by rotating adjustment key 18, adjusting nut 15 is allowed to adjust screw thread 13 sections of movements at turning cylinder 9, can move left and right together with adjusting nut 15 near the push block 16 that guide pin 21 is housed with adjusting nut 15, compression or release pressure spring 12, pressure is applied by compression spring 12 pairs of pressure blocks 11, 6 steel balls 5 that transmission clutch ring 6 plum blossom hole inner ring 27 is equipped with tightly are pressed in the groove 10 of turning cylinder 9 end face of flange, during adjustment, to determine the size of regulated moment of torsion relative to the shift position that transparent scale 20 is carved with moment of torsion dynamics by push block 16 cylindrical being carved with mpving wire 23, when torsion reaches demand, lock with the lock-screw 22 on push block 16 cylindrical again.
After drive motors 2 of the present invention is energized and starts, speed changer 3 through connecting and adapter flange 4 drive transmission clutch ring 6 to rotate, the transmission clutch ring 6 rotated drives turning cylinder 9 to rotate by 6 steel balls 5 in circle, and the quick-release dop 8 installed eventually through turning cylinder 9 front end drives the electric screwdriver head in dop or sleeve to implement screw assembling.After screw is in place, during the setting elastic force of the turning cylinder 9 be rotated further due to load torsion overpressure spring 12,6 steel balls 5 can depart from from the groove 10 of turning cylinder 9 shaft flange end face, compression spring 12 is compressed and pressure block 11 is moved to the left, progressively near proximity transducer 25, the LED 26 on hand-held housing 1 is transshipped and is indicated electric tool overload, and departs from the sound of groove 10 with steel ball 5, turning cylinder 9 shuts down, and adapter flange 4 to dally 1/6 circle relative to turning cylinder 9.
After electric tool lock screw leaves, drive motors 2 is energized startup again
orlock next screw, adapter flange 4 continues to drive transmission clutch ring 6 to rotate, 6 steel balls 5 in transmission clutch ring 6 band moving-coil forward the next groove 10 of turning cylinder 9 shaft flange end face to, and after torsion arrangement of clutch resets, electric tool turns round again, until lock screw transships again.
Set up by the transmission clutch ring 6 with plum blossom hole inner ring 27 between the adapter flange 4 that Ball type torsion clutch type electric tool of the present invention drives at drive motors 2 and speed changer 3 and turning cylinder 9, steel ball 10, pressure block 11, compression spring 12, the arrangement of clutch that adjusting nut 15 and push block 16 form, rotate adjusting nut 15 by adjustment key 18 and regulate distance between push block 16 and pressure block 11, realize the stressed control of compression spring 12, serve the effect of adjustment means locking torque magnitude, electrodeless adjustment moment of torsion can be realized, meet the demand of the different torsion of electric tool, be convenient to production line efficiently quick, completing of safe and reliable assembly process.
Ball type torsion clutch type electric tool of the present invention, can realize electrodeless adjustment moment of torsion, for meeting the different torsion demands of various electric tool, is convenient to the carrying out that production line assembly process is efficiently quick, safe and reliable.The groove 10 that turning cylinder 9 shaft flange end face of the present invention is provided with, or through hole 10 ＇ being set to installation steel ball 5 at interval, as shown in Figure 5 b, and transmission clutch ring 6 is equipped with the plum blossom hole inner ring 27 of steel ball 5, or be set in circle face with sphere pit 27 ＇ of steel ball 5 corresponding matching in turning cylinder 9 through hole 10 ＇ as shown in Figure 4 b.Such arrangement of clutch structure is for the less small-sized electric tool of lock screw moment of torsion, the sensitivity of its clutch is higher, slightly exceed torsion setting load, 6 steel balls 5 in turning cylinder 9 through hole 10 ＇ can be deviate to circle face from sphere pit 27 ＇ of transmission clutch ring 6, compression spring 12 is compressed and pressure block 11 is moved to the left, steel ball 5 departs from sphere pit 27 ＇, and turning cylinder 9 shuts down, and adapter flange 4 to dally 1/6 circle relative to turning cylinder 9.
After electric tool lock screw leaves, drive motors 2 is again energized and starts the next screw of locking, adapter flange 4 continues to drive transmission clutch ring 6 to rotate, in sphere pit 27 ＇ of transmission clutch ring 6 and turning cylinder 9 through hole 10 ＇ after steel ball 5 contraposition, steel ball 5 falls into sphere pit 27 ＇, after torsion arrangement of clutch resets, electric tool turns round again, until lock screw transships again.
Above-mentioned embodiment is an example of the present invention, is not used to limit enforcement of the present invention and interest field, and all equivalences made according to the content described in the present patent application scope of patent protection change and modify, and all should be included in the present patent application the scope of the claims.
