Small pressure device

Abstract

The invention discloses a small pressure device comprising a motor, a crankwheel, a first connecting rod, a second connecting rod, a third connecting rod, a first revolute pair, a second revolute pair, a third revolute pair, a fourth revolute pair, an upright column, a supporting platform, a slide block and a base; the upper end of the first connecting rod is connected to the upper end of the upright column through the second revolute pair; the lower end of the upright column is fixedly arranged on the base; the lower end of the first connecting rod is connected with the upper end of the second connecting rod through the first revolute pair; the lower end of the second connecting rod is connected to the slide block through the third revolute pair; one end of the third connecting rod is connected to the first revolute pair, and the other end of the third connecting rod is connected to the crankwheel through the fourth revolute pair; the crankwheel is mounted on an output shaft of the motor; and the motor is fixedly arranged on the base through the supporting platform. The power is provided by the motor, and the power of the motor is converted into the bending and stretching motion of the two connecting rods to provide a pressure for one end of each connecting rod, so that the aims of low input power, high output pressure, operation stability and pressure uniformity are achieved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a small pressure device. Background technique [0002] Presses are needed in many occasions in life, such as riveting of rivets, pressing or pressing of objects, etc. There are many large presses on the market, which are expensive and have very complicated structures. Therefore, people choose manual pressing on many occasions, which not only easily hurts hands, but also uses uneven strength, slow speed, high labor intensity and low work efficiency. Contents of the invention [0003] The invention aims at the deficiencies of the prior art and provides a small pressure device with simple structure. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A small pressure device, including a motor, a crank wheel, a first connecting rod, a second connecting rod, a third connecting rod, a first rotating pair, a second rotating p...
