Abstract
The invention discloses a pneumatic rotary variable-speed feeding device which comprises a support. A cylinder is fixed onto the support, a piston cavity of the cylinder is eccentrically hinged onto a rotary wheel, and a driving gear is coaxially arranged on the rotary wheel; a driven gear is arranged on the driving gear in a meshed manner, and a transmission roller is eccentrically arranged on the driven gear; a feeding rocker arm is further hinged onto the support, a workpiece clamping jaw is arranged at a free end of the feeding rocker arm, a slide groove is formed in the middle section of the rocker arm, and the transmission roller is fixed into the slide groove. The pneumatic rotary variable-speed feeding device has the advantages that a piston rod is driven by the cylinder to drive the rotary wheel to rotate in a reciprocating manner, the driving gear which is coaxially arranged on the rotary wheel also rotates and simultaneously drives the driven gear meshed with the driving gear to rotate, the transmission roller is eccentrically arranged on the driven gear and is inserted into the slide groove in the middle section of the rocker arm, and accordingly the rocker arm can be driven by the transmission roller to swing around a hinged point when the driven gear rotates.
Description
Technical field
The present invention relates to a kind of pay-off, be specifically related to a kind of pneumatic type revolution variable speed feed device.
Background technology
Swinging gear is a kind of common physical construction, is widely used in various physical constructions.General swinging gear is all to adopt motor to drive, and by its rotation of driven by motor, realizes reciprocal swing process.But the fork of driven by motor is difficult to accomplish the velocity variations in swing process, and can not rest on maximum position for a long time, otherwise have the situation generation that damages motor.
Summary of the invention
The object of the present invention is to provide a kind of pneumatic type revolution variable speed feed device, the motor-driven swinging gear of abandoning tradition, has advantages of that feeding swing speed is variable.
For achieving the above object, technical scheme of the present invention is: pneumatic type revolution variable speed feed device, comprise support, and on described support, be fixed with a cylinder, the plunger shaft Eccentric-hinge of described cylinder is connected on gyrostat, is coaxially provided with a driving gear on described gyrostat; On described driving gear, be engaged with a driven gear, on described driven gear, bias is provided with a drive balls; On described support, be also hinged with a feeding rocking arm, described feeding rocking arm free end is provided with work-holding jaw, and the stage casing of described rocking arm offers a chute, and described drive balls is fixed in chute.
While adopting technique scheme, under cylinder drives, piston rod drives gyrostat reciprocating rotation, on gyrostat, the coaxial driving gear arranging also turns round, drive with the driven gear of its engagement simultaneously and rotate, due to eccentric setting on driven gear a drive balls, and drive balls inserted in the chute in rocking arm stage casing, so just makes driven gear can drive rocking arm to swing around hinge-point by drive balls in the process of rotating.And because drive balls is eccentric setting, so the swing speed of rocking arm occur two ends fast in the middle of slow situation, its swing speed can need to be regulated according to actual feeding.
Further, described support vertically arranges, and described gyrostat, driving gear, driven gear and fork are arranged on the same side of support.The arrangement of above-mentioned parts can reducing mechanism overall volume, reach the requirement of use.
Further, on described support, be also provided with the block of restriction rocking arm amplitude of fluctuation.By the amplitude of fluctuation that block can manual control rocking arm is set, and then realistic use needs.
Further, described block is provided with pressure sensor, and described pressure sensor connects the control setup of cylinder by treater.By pressure sensor, collect signal, can pass through the action of the automatic control cylinder of treater, realize automatic reciprocating feeding.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of pneumatic type revolution variable speed feed device embodiment of the present invention.
The specific embodiment
As shown in Figure 1, pneumatic type revolution variable speed feed device of the present invention, comprises support, is fixed with a cylinder 1 on support, and the piston of cylinder 1 catches up with Eccentric-hinge to be connected on gyrostat 11, on gyrostat 11, with axle key, connects a driving gear 2; On driving gear 2, be engaged with a driven gear 3, on driven gear 3, bias is provided with a drive balls 31; On support, be also hinged with a Rocker arm 4, the stage casing of described Rocker arm 4 offers a chute 41, and drive balls 31 is fixed in chute 41.On support, be also provided with the block 5 of restriction Rocker arm 4 amplitude of fluctuation.By the amplitude of fluctuation that block 5 can manual control Rocker arm 4 is set, and then the use of realistic feeding needs.Block 5 is provided with pressure sensor, and described pressure sensor connects the control setup of cylinder 1 by treater.By pressure sensor, collect signal, can pass through the action of the automatic control cylinder 1 of treater, realize automatic reciprocating feeding.
During use, under cylinder 1 drives, piston rod drives gyrostat 11 reciprocating rotations, on gyrostat 11, the coaxial driving gear 2 arranging also turns round, drive with the driven gear 3 of its engagement simultaneously and rotate, due to eccentric setting on driven gear 3 drive balls 31, and drive balls 31 inserted in the chute 41 in Rocker arm 4 stage casing, so just makes driven gear 3 can drive Rocker arm 4s swing around hinge-point by drive balls 31 in the process of rotating.And because drive balls 31 is eccentric settings, so the swing speed of Rocker arm 4 occur two ends fast in the middle of slow situation, its swing speed can be regulated according to actual needs.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; do not departing under the prerequisite of structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
