Technical field
Patent of the present invention relates to a kind of percussion mechanism, is specially a kind of device that is used for motor rotor conducting bar is impacted tensioner.
Background technology
The AC traction electric motor rotor bar is in assembling process, adopt the distortion extrusion principle with its tensioner in iron core, avoid the displacement that is in operation, specific practice is that sliver is packed in the iron core, upper surface at sliver is squeezed into several sections U-lags along its length, makes its distortion tensioner in the sliver groove.In traditional technology, manually knock blunt type flat chisel with hand hammer, produce distortion on sliver top.Such operation makes distortion groove depth and length irregular, and the tensioner degree of each one there are differences, and human factor will make the assembly quality instability of sliver, be difficult to reach the quality of designing requirement.Efficient is low, and labour intensity is the production requirement of incompatibility automation size greatly also.
Summary of the invention
Production efficiency is low when manually knocking the tensioner sliver for solving, and the quality problem of unstable the invention provides and a kind ofly replaces manually-operated motor rotor conducting bar punching machine with automated production.
The technical solution used in the present invention is: a kind of motor rotor conducting bar punching machine, comprise the clamp system that is fixed on the body, by the feed mechanism and the interrupted division positioner of control unit control, be fixed with the percussion mechanism by control unit control on the described feed mechanism, this percussion mechanism comprises a blow cylinder by control unit control that is connected with drift.Rotor is fixed by clamp system and is connected with the interrupted division detent mechanism, and the action of control feed mechanism makes connected percussion mechanism drift contact rotor bar, starts blow cylinder and impacts drift, makes drift squeeze into sliver, forms the distortion groove.Because rotor bar circumferentially has several, after dashing the sliver that risen, be turned back to next sliver groove position by the interrupted division positioner and carry out operation.Be to realize automated production, more than each mechanism, device control by control unit.
In order to improve the accuracy of rotor revolution and location, described interrupted division positioner comprises a ratchet mechanism and a positioner, described ratchet mechanism comprises ratchet, be fixed in the pawl base on the body surface of ratchet below, the pawl base upper end is connected with the ratchet that cooperates with ratchet, one side of pawl base is connected with cylinder, described positioner is arranged on ratchet one side, comprises cylinder and the alignment pin that is connected with cylinder.
The present invention uses Numeric Control Technology, punching press principle and interrupted division detent mechanism, pneumatic means to combine, and forms automation processing, has changed traditional manual work mode.By changing ratchet and drift, the technological parameter in the update routine can carry out the motor rotor conducting bar punching of plurality of specifications.Equipment comes into operation, and can reduce labor intensity, and increases work efficiency, and stabilized product quality reaches designing requirement, thereby realizes automation, product diversification production.

Embodiment
A kind of motor rotor conducting bar punching machine of the present invention, as shown in Figure 1, comprise the clamp system that is fixed on the body 1, by the feed mechanism and the interrupted division positioner 2 of control unit control, be fixed with the percussion mechanism 3 by control unit control on the described feed mechanism, this percussion mechanism 3 comprises a blow cylinder 5 by control unit control that is connected with drift 4.Control unit is contained in the control box 17.
Described percussion mechanism 3 comprises that also is arranged on the guide pad 6 that drift 4 the place aheads cooperate with drift 4.Guide pad 6 has angular displacement, the buffering of restriction drift and controls the effect of the degree of depth of distortion groove.Guide pad 6 can be made with elastomeric material.
As shown in Figure 3, described interrupted division positioner 2 comprises a ratchet mechanism and a positioner, described ratchet mechanism comprises the number of teeth ratchet 7 identical with the groove number of rotor 18, is fixed in the body 1 lip-deep pawl base 8 of ratchet 7 belows, pawl base 8 upper ends are connected with the ratchet 9 that cooperates with ratchet 7, one side of pawl base 8 is connected with the cylinder 10 by control unit control, described positioner is arranged on ratchet 7 one sides, comprises cylinder 11 and the alignment pin 12 that is connected with cylinder 11 by control unit control., with clip 18 of ratchet 7 and rotors are connected during use, rotate synchronously.When needing revolution, drive alignment pin 12 by control unit control cylinder 11 and extract ratchet 7, make ratchet 7 be in free state, then the piston rod of cylinder 10 promotes pawl base 8 and moves certain stroke, ratchet 9 is stirred ratchet 7 and is rotated a tooth, and promptly rotor 18 rotates a groove, at this moment, alignment pin 12 inserts in the ratchet 7, pins ratchet 7.Because ratchet 9 has irreversibility, returns under the effect at cylinder 10 piston rods, ratchet 9 is crossed ratchet 7 and is got back to initial position, and disc spring is in ratchet 9 and pushes away the dentation attitude, wait for revolution next time.
For the ease of adjusting the position of percussion mechanism 2, feed mechanism comprises and moves radially mechanism 13 and longitudinal moving mechanism 14 by control unit control.Move radially mechanism 13 make percussion mechanism 3 near or leave rotor bar, longitudinal moving mechanism 14 makes percussion mechanism 3 move along the rotor bar length direction, radially reaches length feed and all adopts worm drive, driven by servomotor, the control of digital control system control unit.
Described clamp system comprises main spindle box 15 and the tailstock 16 that is separately fixed at body 1 two ends, is respectively equipped with corresponding top on main spindle box 15 and the tailstock 16.Top can the revolution on the main spindle box, rotor with axle be contained in two corresponding top between.
Control unit adopts Numeric Control Technology, has one-step control, and work step adjustment and whole operation realize controlling automatically, finishing continuously function.
The course of work is controlled by control unit, during work, the rotor 18 that will penetrate sliver 19 earlier be installed in can rotating main spindle box 15 and tailstock 16 between, adjust first sliver 19 and be in correct initial position, percussion mechanism 3 is moved by control unit control according to the program that technological requirement is compiled, radial feed at first, drift 4 is contacted with sliver 19, under percussion, drift 4 forms the distortion of certain depth on sliver 19 surfaces, drive percussion mechanism 3 by feed mechanism and move and constantly impact, can on this sliver 19, form some distortion grooves of technological requirement, make sliver 19 tensioners in rotor 18 along rotor 18 length directions.After sliver 19 tensioners, ratchet mechanism is turned back to next root sliver 19 position with rotor, and positioner is locked it, dashes and rises.Constantly circulation is implemented, and finishes up to whole operations.
