High speed cam exchange mechanism with torque compensation

Abstract

The invention discloses a high-speed cam exchange mechanism with torsion compensation in the field of machine tools, which includes an exchange pallet and a processing table and a preparation table respectively arranged in the gaps at both ends of the exchange pallet. The lower planes of the processing table and the preparation table are both rectangular. The array has an upper cone seat, and a rotating table is fixed directly under the processing table and the preparation table, and a lower cone seat matching the upper cone seat is arranged on the rotating table. The lifting mechanism is intermittently matched, and the two sides of the housing are provided with a symmetrical balance mechanism, which is flush with the lifting mechanism, and one side of the housing is provided with a torque compensation mechanism connected with the lifting mechanism. In the present invention, the balance mechanism prevents the exchange pallet from tilting and causing jamming during the lifting process, a torque compensation mechanism is added to increase the torque of the exchange cam, and a movable dislocation structure is set at the junction of the upper and lower cone seats to increase firmness.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to a high-speed cam exchange mechanism with torsion compensation. Background technique [0002] There are many ways to process mechanical parts in modern machinery manufacturing: in addition to cutting, there are also casting, forging, welding, stamping, extrusion, etc. The final machining is done by cutting on the machine tool. Machine tools play an important role in the modernization of the national economy. [0003] According to the market demand, a machine tool with double worktables is derived. During operation, the positions of the two worktables can be rotated to achieve different processing. However, when the position is changed, the pallet is easily tilted due to the different weights on both sides, causing the lifting process to get stuck. It is dead, and the torque required in the lifting process is relatively high, which requires high power of the power source. A...

[0003] According to the market demand, a machine tool with double worktables is derived. During operation, the positions of the two worktables can be rotated to achieve different processing. However, when the position is changed, the pallet is easily tilted due to the different weights on both sides, causing the lifting process to get stuck. dead, and the torque required during the lifting process is relatively high, which requires a high power source. After the table is rotated and fixed on the turntable, the movement of the turntable will be caused by the vibration during processing.
