Manipulator stroke amplification device

Abstract

The invention relates to a travel amplifying device for a mechanical hand, and belongs to the technical field of automated machines. The travel amplifying device comprises a fixed guide base, a sliding guide base, a fixed rack, a travel amplifying rack, an executing base, a transition transmission mechanism and a power transmission mechanism; a fixed guide base idler wheel receding cavity is formed in one side of the fixed guide base, the upper portion and the lower portion of the fixed guide base idler wheel receding cavity are provided with an upper fixed guide base idler wheel guide strip and a lower fixed guide base idler wheel guide strip respectively, a sliding guide base idler wheel receding cavity is formed in one side of the sliding guide base, and the upper portion and the lower portion of the sliding guide base idler wheel receding cavity are provided with an upper sliding guide base idler wheel guide strip and a lower sliding guide base idler wheel guide strip respectively; the fixed rack is arranged at the bottom of the fixed guide base; the travel amplifying rack is arranged at the bottom of the sliding guide base; the executing base is arranged between the fixed guide base and the sliding guide base, the executing base is provided with an executing base rack at the top and an upper idler wheel shaft on the upper portion, a front upper idler wheel and a rear upper idler wheel of the executing base are arranged on the upper idler wheel shaft, a lower idler wheel shaft is arranged on the lower portion of the executing base and provided with a front lower idler wheel and a rear lower idler wheel of the executing base; the transition transmission mechanism is connected with the bottom of the executing base; the power transmission mechanism is arranged in the middle of the fixed guide base. The travel can be amplified in a doubled mode, motion resistance is small, and the travel amplifying device is simple in structure.

Description

technical field [0001] The invention belongs to the technical field of automatic machinery, and in particular relates to a stroke amplification device of a manipulator. Background technique [0002] The aforementioned manipulator stroke amplification device can also be called a manipulator stroke multiplication device, which can save space when it is arranged between two adjacent stations and the product on one station is transferred to another station, and Similar technical information can be seen in the published Chinese patent documents, typically such as the "magnifying stroke device" recommended by the authorized announcement number CN203258005U. Set the executive plate (also called the executive seat, the same below), when the drive belt drives the drive plate to move, and the drive belt drives the executive plate to move at the same time, to achieve double the stroke enlargement (for details, please refer to paragraphs 0015 to 0023 of the patent specification ).

Problems solved by technology

Objectively speaking, this patent solution can reflect the technical effect described in paragraph 0010 of its description, but it has the following shortcomings: First, although the patent does not specifically point out whether a pair of transmission wheels are arranged at intervals on both sides of the drive plate, and A transmission belt is sheathed on a pair of transmission wheels, but if a pair of transmission wheels and a transmission belt are only arranged on one side of the drive plate, then due to the lack of balance on both sides of the drive plate, the movement effect of the drive plate and the executive plate will be affected. A pair of transmission wheels are arranged on both sides of the drive plate (one side is coaxial with the transmission wheel on the other side), and a transmission belt is sleeved on the pair of transmission wheels on both sides, then when the transmission belts on both sides are tightened When the degree is inconsistent, it will also affect the smooth movement of the drive plate and the executive plate; second, because the transmission belt is more sensitive to thermal expansion and contraction caused by ambient temperature changes, and usually elongates during use, Therefore, it is necessary to adjust or even replace it in time, thereby causing confusion to the use; third, because the guide rail sliding pair is used between the drive plate and the mounting plate, and the guide rail sliding pair is also used between the executive plate and the drive plate, the movement resistance is large, and it is not easy to It is beneficial to save the energy (electric energy) consumption of the motor of the power transmission mechanism used to drive the transmission wheel, which is specifically manifested in the selection of a motor with relatively large power; Fourth, the patent does not give the enlightenment of the transmission connection between the power transmission mechanism and the transmission wheel
