Problems solved by technology

[0002] The working medium of pneumatic transmission is clean compressed air. Its advantage is that it will not easily produce pollution like hydraulic transmission. At the same time, the piston movement speed of pneumatic transmission is significantly higher than that of hydraulic transmission, so the production efficiency is higher; Leakage, so that the system pressure P cannot be too high, generally P=0.4~0.7 MPa

Embodiment Construction

[0016] The design will be further described below in conjunction with the accompanying drawings of the description.

[0017] like figure 1 As shown, a three-time booster mechanism is characterized in that it includes a cylinder 1 and a primary booster hinge rod 2, a roller 3, a secondary booster hinge rod 4, a slide rod 5, and a force output member symmetrically arranged on both sides of the cylinder 1. 6. Return spring 7, the piston of the cylinder 1 is hingedly connected with the primary booster hinge rod 2 through the piston rod, the primary booster hinge rod 2 is hingedly connected with the roller 3 arranged in the guide hole, and the secondary booster The hinge bar 4 is hingedly connected with the roller 3 and the slide bar 5 arranged in the guide groove. The free end of the slide bar 5 is provided with a wedge, and the wedge is slidably connected with the force output part 6, and a reset is provided on the force output part. Spring 7.

Abstract

The invention discloses a three-time force-amplifier. The three-time force-amplifier is characterized by comprising an air cylinder, and primary force amplifying toggles, rollers, secondary force amplifying toggles, sliding rods, force output pieces and reset springs, which are symmetrically arranged on two sides of the air cylinder; a piston of the air cylinder is hinged to the primary force amplifying toggles through a piston rod; the primary force amplifying toggles are hinged to the rollers arranged in guide holes; the secondary force amplifying toggles are hinged to the rollers and the sliding rods arranged in guide slots; the free ends of the sliding rods are provided with wedges; the wedges are in sliding connection with the force output pieces; the reset springs are arranged on the force output pieces. The clamping force is subjected to three-time amplification through an angle effect, and the pressure of the air cylinder or the size of the air cylinder can be effectively reduced; the three-time force-amplifier can meet the requirement that the piston rod of the air cylinder is perpendicular to the output direction of the clamping force for work by using single input force.

Description

technical field [0001] The design relates to a three-time boosting mechanism, which belongs to the technical field of machine fixtures. Background technique [0002] The working medium of pneumatic transmission is clean compressed air. Its advantage is that it will not easily produce pollution like hydraulic transmission. At the same time, the piston movement speed of pneumatic transmission is significantly higher than that of hydraulic transmission, so the production efficiency is higher; Leakage, resulting in system pressure P can not be too high, generally P = 0.4 ~ 0.7 MPa. Therefore, in order to increase the clamping force of the pneumatic clamp, it must be achieved by increasing the diameter of the piston or introducing an appropriate booster mechanism between the cylinder and the force output device. Since the first method will increase the overall size of the clamp, Therefore, the second method is usually used to improve the clamping force of the fixture. Contents...
