Problems solved by technology

[0003] Traditional fixtures mainly use liquid pressure or gas pressure as the driving source, and some are driven by electric motors or electromagnetic forces. These fixtures usually require complex driving equipment and additional power sources, resulting in increased equipment complexity and cost.
At the same time, hydraulic clamps are likely to cause environmental pollution due to hydraulic oil leakage, and pneumatic clamps cause noise pollution due to exhaust, which is not compatible with the current green manufacturing concept
Manual fixtures usually use manpower as the driving source, and the degree of greening and flexibility is very high, but there are not many studies on it at present, mainly because the power that manpower can provide is very small (less than 150N for frequent action occasions) and Manpower cannot maintain the clamping state of the fixture for a long time

Abstract

The invention discloses a manual pressing device based on worms, worm wheels and crank connecting rod transmissions. The manual pressing device comprises a rotary shaft, wherein at least two worms are fixedly arranged on the rotary shaft, the worm wheels meshed with the worms are arranged under the corresponding worms, the crank connecting rod transmissions are arranged on the worm wheels, and the tail ends of the crank connecting rod transmissions are connected to the same press block. The symmetrical synchronous multi-point driving is achieved, the manual pressing device is compact in structure, simple and convenient to use and rapid in positioning and pressing, the synchronous multi-point or multi-station pressing can be achieved according to the demands of workpieces, and accordingly labor productivity and product quality are improved.

Description

technical field [0001] The invention relates to a manual pressing device based on the transmission of a worm gear and a crank connecting rod, which belongs to the technical field of machinery. Background technique [0002] Traditional product design and manufacturing focus on product cost and performance first. However, the increasing environmental pollution has become a major problem that plagues the development of the global society. The intensification of environmental pollution has damaged the stability of the earth's ecosystem, fundamentally Has endangered human survival and sustainable development. With the progress of society, the concept of sustainable development has gradually become popular, and the greening of the manufacturing process has been paid more and more attention. The key part of this is the greening of the clamping device. [0003] Traditional fixtures mainly use liquid pressure or gas pressure as the driving source, and some are driven by electric mot...
