Description
Technical field:
The utility model relates to a kind of electronic constant torque wrench location counter-force mechanism automatically that tights a bolt in (nut) process, is suitable for the electronic constant torque wrench of single shaft.
Background technology:
At present, the tight a bolt counter-force of (nut) of electronic constant torque wrench must overcome by counter-force arm.At present, known electronic constant torque wrench is the position of adjusting counter-force arm by manually-operated, operation inconvenience, and efficient is low.
Summary of the invention:
In order to overcome the deficiency that above-mentioned prior art exists, the utility model provides a kind of electronic constant torque wrench to locate counter-force mechanism automatically, can seek the counter-force arm strong point easily automatically.
The technical solution of the utility model is: the automatic location counter-force mechanism of this electronic constant torque wrench, comprise precursor, pull axle, be installed in the cover of pulling of pulling shaft end, counter-force arm, it is characterized in that described pulling is equipped with homoaxial counter-force cover on the axle, counter-force is overlapped and is pulled bearing is installed between the axle, the counter-force cover is positioned at the outer end of precursor and connects a counter-force arm by spline, the other end is positioned at precursor and connects the ring gear of a planetary wheeling mechanism by connecting pin, freely be connected between ring gear and the precursor, be provided with a coaxial friction pad that is fixedly connected on the precursor inwall between counter-force cover and the precursor, friction pad is provided with the connecting pin locating hole, described connecting pin one end is that sphere and this end are positioned at the surface groove on the ring gear end face, be provided with back-moving spring between connecting pin and the counter-force cover, the planetary wheel carrier of planetary wheeling mechanism is the other end of pulling axle, pull the axle between planetary outer end and the sleeve in precursor, be provided with bearing, be provided with steel ball between bearing block end in precursor and the ring gear end, planetary gear and centre wheel engagement; Described counter-force arm is provided with a radial hole, and this radial hole is built-in with alignment pin, retainer spring, and screw is positioned at the outside of retainer spring.
The radially outer ring of friction pad is provided with the outer plum blossom that cooperates with the precursor inwall, also can be the connection of other bond structure.
During work, in planetary gear speed reducing mechanism, when tighting a bolt or the resistance of nut during greater than the frictional force of ring gear, it is fixing promptly to be equivalent to pull axle, this moment, ring gear drove the counter-force arm rotation by connecting pin, and after counter-force arm supported to the counter-force position that can bear bolt, counter-force arm was fixed.Because of connecting pin the moving of inclined-plane, ring gear end, connecting pin is connected as a single entity precursor, ring gear, counter-force arm, this moment, all counter-forces of bolt were born by counter-force arm.Pull axle this moment and drive and to pull cover and begin to tighten/demounting bolt or nut, work finishes, and spring makes connecting pin reset automatically.
The beneficial effects of the utility model are: use the electronic constant torque wrench of this mechanism to tighten or can seek the counter-force arm strong point easily automatically during demounting bolt (nut), counter-force arm can 360 ° of rotations, can be supported on easily on any position, simple to operate, improved operating efficiency.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is a cutaway view of the present utility model.
Among the figure: 1 pulls cover, 2 counter-force arm, and 3 screws, 4 retainer springs, 5 alignment pins, 6 springs, 7 connecting pins, 8 ring gears, 9 steel balls, 10 bearing blocks, 11 centre wheels, 12 planetary gears, 13 precursors, 14 friction pads, 15 counter-force covers, 16 pull axle,
The specific embodiment:
From accompanying drawing as can be seen, the overall structure of the automatic location counter-force mechanism of the electronic constant torque wrench of the utility model is: it comprises precursor 13, pull axle 16, be installed in pull shaft end pull parts such as cover 1, counter-force arm 2, planetary wheeling mechanism.Pull axle and be equipped with homoaxial counter-force cover 15 on 16, counter-force cover 15 with pull spools 16 between bearing is installed.Counter-force cover 15 is positioned at precursor 13 outer ends and connects a counter-force arm 2 by spline, and described counter-force arm 2 is provided with a radial hole, and this radial hole is built-in with alignment pin 5, retainer spring 4, and screw 3 is positioned at the outside of retainer spring.The other end of counter-force cover 15 is positioned at precursor 13 and connects the ring gear 8 of a planetary wheeling mechanism by connecting pin 7, freely be connected between ring gear 8 and the precursor 13, be provided with a coaxial friction pad 14 that is fixedly connected on the precursor inwall between counter-force cover 15 and the precursor 13, friction pad 14 is provided with the connecting pin locating hole, and the radially outer ring of friction pad 14 is provided with the outer plum blossom that cooperates with precursor 13 inwalls.Described connecting pin 7 one ends are that sphere and this end are positioned at the surface groove on ring gear 8 end faces, are provided with back-moving spring 6 between connecting pin 7 and the counter-force cover 15, and the planetary wheel carrier of planetary wheeling mechanism is the other end of pulling axle 16.Be provided with bearing pulling axle 16 between the outer end of planetary gear 12 and the bearing block in precursor 13 10, be provided with steel ball 9 between bearing block 10 ends in precursor 13 and ring gear 8 ends, this steel ball 9 is positioned at bearing block 10 end recesses of precursor 13.Planetary gear 12 and centre wheel 11 engagements;
After spanner starts, pull cover 1 tight a bolt earlier (nut), reach and pull axle 16 behind certain moment of torsion and stop operating, pull the frictional force of the power that is subjected to of cover greater than ring gear 8 this moment, centre wheel 11 passes to moment of torsion on the ring gear 8 by planetary gear 12, because it is big to pull the suffered power of axle 16 this moment, it is motionless to pull axle 16, ring gear is unfixing 8 this moments, and ring gear 8 drives counter-force cover 15 by connecting pin 7 and rotates, and counter-force cover 15 drives counter-force arm 2 by spline and rotates.After counter-force arm 2 runs into barrier, stop operating, this moment, the sphere of connecting pin 7 slided in ring gear 8 left side skewed slots, slide into connecting pin 7 engaging friction pads 14 behind the certain position, ring gear 8, counter-force cover 15, friction pad 14, counter-force arm 2 are connected as a single entity at this moment, and because of outer plum blossom and the precursor 13 of friction pad 14 by itself is connected as a single entity, precursor 13 freely is connected with ring gear 8, ring gear 8 does not rotate, and pulls cover 1 this moment and rotates.After hours, spring 6 makes connecting pin 7 withdraw from from friction pad 14 holes automatically and gets back to original position.
