Title:
UNDER-ACTUATED CONNECTING ROD TYPE PINCHING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2020/211724
Kind Code:
A1
Abstract:
Provided is an under-actuated connecting rod type pinching mechanism, comprising a first gear (1), a second gear (1'), a third gear (2), a fourth gear (2'), a linear motion mechanism (3), a multi-connecting rod synchronization mechanism (4), a first conveying roller (5), a second conveying roller (5'), a long-strip-shaped material (6), a linear spring assembly (7), a universal coupling (8) and a drive motor (9), the multi-connecting rod synchronization mechanism (4) comprises a first connecting rod (401), a second connecting rod (402), a third connecting rod (403), a fourth connecting rod (404), a fifth connecting rod (405), a sixth connecting rod (406), a seventh connecting rod (407) and an eighth connecting rod (408), the linear spring assembly (7) comprises a first pressing spring (71), a second pressing spring (72), a sliding block (73) and a support base (74). The under-actuated connecting rod type pinching mechanism improves the single-degree-of-freedom structure form of the prior pinch rollers, so that the pinching mechanism can move at an under-actuated joint while synchronously completing the clamping action, instantaneous clamping acting force is buffered through the linear spring assembly, the clamping mechanism and the clamped workpiece are effectively protected, meanwhile, the service life of device is prolonged.
