Abstract
The invention discloses an indexing closed-loop control system for notching machines. The indexing closed-loop control system comprises a notching machine indexing seat, and a servo motor. An indexing spindle is disposed on the indexing seat of the notching machine indexing seat. A rotary encoder is installed at the tail end of the indexing spindle. The indexing spindle is provided with a gear P4 at the upper end of the rotary encoder. A gear P1 is in drive connection with an output shaft of the servo motor. The indexing closed-loop control system further comprises coaxial gears P12 and P3. The gear P4 meshes with the gear P3. The gear P1 meshes with the gear P2. The servo motor controls the indexing spindle to rotate in a preset path to complete indexing by two-stage drive of the gears P4, P3, P2 and P1. The indexing closed-loop control system has the function of jamming suppression and insensitive to characteristic change of elements, response characteristic of the system can be improved, and accordingly indexing control precision is improved.
Description
Technical field
The present invention relates to motor iron core process equipment notching press field, specifically the calibration closed-loop control system on a kind of notching press.
Background technology
Notching press is the single groove punching out special equipment for stamping-out rotor or stator lamination slotted eye.The punch die of punching out 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, make lamination (punching) make dividing movement by default requirement by indexing means.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 indexing system of numerical control notching press is to adopt servomotor by secondary gear transmission or one-level gear drive, perhaps directly directly drives the rotation of calibration main shaft by servomotor.The calibration control of notching press is to adopt half-closed loop control, namely reads the rotation angle value of P4 gear.The control system antijamming capability of this frame for movement is relatively poor, to the element characteristic sensitive.And then affect precision.
Summary of the invention
The problem that exists for solving prior art, the purpose of this invention is to provide the calibration closed-loop control system on a kind of notching press, adopt the calibration action of closed-loop control system control calibration part, lamination (punching) is rotated by default requirement, guarantee the punching indexing accuracy.
The technical solution used in the present invention is as follows:
Calibration closed-loop control system on the notching press, include the indexing base of notching press, servomotor, it is characterized in that: the calibration main shaft is installed on the indexing base of described notching press, on the shaft end of calibration main shaft rotary encoder is installed, the upper end that is positioned at rotary encoder on the calibration main shaft is equipped with the P4 gear, the output shaft upper driving of servomotor connects the P1 gear, also include coaxial P2, the P3 gear, described P4 gear and the engagement of P3 gear, P1 gear and the engagement of P2 gear, servomotor passes through P4, P3, P2, the secondary transmission of P1 gear, control calibration main shaft is finished the calibration action by default track rotation.
The end of described calibration main shaft adopts shaft coupling to connect with rotary encoder.
Described system can guarantee desired indexing accuracy.
Compared with the prior art, advantage of the present invention is as follows;
The calibration action of the calibration closed-loop control system control calibration part on the notching press that the present invention proposes makes lamination (punching) rotate by default requirement; This mechanism has the ability that suppresses interference, and is insensitive to the element characteristic variation, and can improve the response characteristic of system, thereby improves the control indexing accuracy.
