Description
Technical field
The utility model relates to motor iron core process equipment notching press field, and is a kind of for the slide block hoisting mechanism on the notching press specifically.
Background technology
Notching press is the single groove punching special equipment for stamping-out rotor or stator lamination slotted eye.The punch die of punching rotor or stator lamination is installed between drift (slide block) and the workbench, by pumping of drift (slide block), drives patrix and pumps.Need the lamination (punching) of jet-bedding to be installed on the indexing means with intermittent movement, by indexing means lamination (punching) is rotated by default requirement.When drift (slide block) when moving downward, lamination (punching) does not turn the wait jet-bedding, when drift (slide block) when moving upward, and lamination (punching) rotary index, through the dividing movement in a week, can finish the jet-bedding process of a lamination (punching).At present, the notching press of domestic production there is no this function.In order conveniently to get sheet and film releasing, when particularly adopting the manipulator loading and unloading, traditional mode is to increase ram travel, and consequently the jig frequency of jet-bedding reduces, and fuselage shaking increases, and the running part of Slipper is easy to wear.
The utility model content
The problem that exists for solving prior art, the purpose of this utility model provides a kind of for the slide block hoisting mechanism on the notching press.When a punching process finishing, when slide block was to be rushed, by electrical control, rack-and-pinion oscillating cylinder output shaft rotation drove the eccentric shaft rotation, so that the patrix of slide block and notching die upwards lifts certain height, conveniently gets sheet and film releasing.After putting punching well, the rack-and-pinion oscillating cylinder resets, and drift (slide block) drops to initial position, eccentric shaft position switch induced signal, and by PLC control, locking cylinder promotes, and linear guides pins positioning disk.The retaining mechanism locking eccentric.Slide block (drift) is driven by push rod and pumps, thereby finishes the jet-bedding process.
The technical solution adopted in the utility model is as follows:
Be used for the slide block hoisting mechanism on the notching press, include eccentric shaft, eccentric shaft left side, right-hand part are set with the left and right large cover that is fixed on the lathe bed outward, the left end of eccentric shaft is equipped with positioning disk, have a breach on the positioning disk, the linear guides that horizontal slide-and-guide arranges is housed on the lathe bed, breach matches with the right-hand member of linear guides, the left end of linear guides is fixedly connected with locking cylinder, and the right-hand member of eccentric shaft connects with the rack-and-pinion oscillating cylinder by shaft coupling; The middle part of eccentric shaft is equipped with connecting rod by bearing, and the connecting rod lower end is connected with the slide block drift.
The end of the large cover in the described right side is installed with supporting base, and supporting base is fixedly connected with connecting plate by screw, and the connecting plate outside is fixedly connected with the rack-and-pinion oscillating cylinder.
Adopt expansion sleeve to connect between the installing hole of described positioning disk and the eccentric shaft.
When the off-centre of described eccentric shaft was in upper/lower positions, namely slide block was in the stamping-out state, and eccentric shaft pins by the retaining mechanism of left end, does not rotate.
The action of the rack-and-pinion oscillating cylinder of described eccentric shaft right-hand member and the locking cylinder of left end is by location sensitive switch feedback, and PLC control realizes the action interlocking.
Compared with the prior art, advantage of the present utility model is as follows:
What the utility model proposes is used for slide block hoisting mechanism on the notching press, and its advantage is: the hoisting depth of slide block is that the eccentric distance by eccentric shaft obtains, and does not need to increase ram travel.Install the notching press of this mechanism when stamping-out, vibrate littlely, precision is high, and jet-bedding speed is fast.Particularly when the automaticity of raising equipment, when needing to increase manipulator or robot charge, provide certain convenience.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the connection diagram of this positioning disk and locking cylinder.
The specific embodiment
Referring to Fig. 1, be used for the slide block hoisting mechanism on the notching press, include eccentric shaft 1, eccentric shaft 1 left side, right-hand part is set with a left side of being fixed on the lathe bed 4 outward, right large cover 2,3, the left end of eccentric shaft 1 is equipped with positioning disk 12, adopt expansion sleeve 11 to connect between the installing hole of positioning disk 12 and the eccentric shaft 1, have a breach on the positioning disk 12, horizontal slide-and-guide is provided with linear guides 13 on the lathe bed 4, the breach of positioning disk 12 matches with the right-hand member of linear guides 13, the left end of linear guides 13 is fixedly connected with locking cylinder 14, and the right-hand member of eccentric shaft 1 connects with rack-and-pinion oscillating cylinder 8 by shaft coupling 9; The middle part of eccentric shaft 1 is equipped with connecting rod 15 by bearing 16, and connecting rod 15 lower ends are connected with slide block 10; The end of right large cover 3 is installed with supporting base 5, and supporting base 5 is fixedly connected with connecting plate 7 by screw 6, and connecting plate 7 outsides are fixedly connected with rack-and-pinion oscillating cylinder 8.
When needs promote slide block 10, control by PLC.Locking cylinder 14 is by the pneumatic control feedback, and pulling linear guides 13 moves to left, and breaks away from positioning disk 12, simultaneously position switch 17 feedback signals of linear guides 13.Then, 8 actions of rack-and-pinion oscillating cylinder drive eccentric shaft 1 rotation.By bearing 16, connecting rod 15 upwards promotes certain height with movable slider 10.
When slide block 10 need to reset stamping-out, control by PLC.Rack-and-pinion oscillating cylinder 8 resets, eccentric shaft 1 reverse rotation resets, location sensitive switch 18 feedback signals by positioning disk 12, then promoting linear guides 13 with inlet casing 14 moves to right, insert in the breach of positioning disk 12, position switch 17 feedback signals of while linear guides 13, thereby the position of locking eccentric 1.Slide block 10 just can pump, and realizes stamping-out.
