Description

Technical Field

[0001] The present invention relates to the technical field of machine tool crankshafts, and particularly to a servo-pulling crankshaft compensation device. Background Art

[0002] The feeding devices of high-speed presses and high-speed automatic stamping production lines for air-conditioning fins have two structural forms: mechanical structure and servo feeding structure. Among them, due to the complex transmission system, many connecting parts, large feeding gaps and difficult elimination of the mechanical structure, the use of the mechanical feeding mechanism in high-speed and ultra-high-speed presses and air-conditioning fin production lines is restricted. At present, the servo feeding mechanism has been widely used because of its small feeding gap, high feeding accuracy and easy improvement of feeding speed.

[0003] At present, the servo feeding motor realizes the feeding action by sending signals from an encoder that rotates synchronously with the crankshaft. Since it takes a certain time for the encoder signal to be transmitted to the servo system and also a certain time for the signal to reach the servo system until the action is output, the feeding action (feeding position) often lags behind the crankshaft by a certain angle. The higher the equipment speed (crankshaft speed), the larger the lag angle, resulting in a greater deviation between the feeding position and the crankshaft angle, and ultimately leading to poor stamping and punching of the equipment. Summary of the Invention

[0004] The purpose of the present invention is to provide a servo-pulling crankshaft compensation device with synchronous feeding position and crankshaft angle and improved feeding speed to solve the problems in the prior art.

[0005] The technical solution of the present invention is: a servo-pulling crankshaft compensation device, the compensation device includes a crankshaft pulley, a feeding pulley, a translation pulley one, a translation pulley two, a transition pulley one, a transition pulley two, a transition pulley three, a transition pulley four, a synchronous belt, a translation plate, a crankshaft output shaft, a crankshaft, a crankshaft encoder, a mounting seat, a coupling shaft, a coupling and a feeding encoder; The translation pulley one and the translation pulley two are symmetrically and fixedly arranged on the translation plate and translate synchronously with the translation plate. The transition pulley one, the transition pulley two, the transition pulley three and the transition pulley four are symmetrically arranged in pairs between the translation pulley one and the translation pulley two. The translation pulley one and the translation pulley two are respectively driven by the transition pulley one, the transition pulley two, the transition pulley three and the transition pulley four to rotate synchronously. The crankshaft pulley and the feeding pulley are connected to the synchronous belt and rotate synchronously; The crankshaft pulley is connected to the crankshaft through the crankshaft output shaft. The crankshaft encoder is fixedly arranged on the mounting seat and is connected to the crankshaft pulley through the coupling shaft and the coupling.

[0006] Further, the crankshaft encoder rotates synchronously with the crankshaft.

[0007] Further, the feeding belt pulley is connected to the feeding encoder through a coupling and rotates synchronously.

[0008] The beneficial effects of the present invention are as follows: During the production process of the machine tool, the feeding signal angle can be changed by the translation servo motor, so that the feeding action is advanced, compensating for the actual lag of the feeding action behind the crankshaft signal time due to the feeding signal transmission time and the operation time of the servo feeding motor. The feeding action can be synchronized with the crankshaft signal, which can increase the feeding speed, and then increase the machine tool speed to achieve the purpose of improving production efficiency.
