Abstract
The utility model relates to a cross-wheel deceleration swing feeding mechanism and belongs to a feeding mechanism. A pin wheel is driven by a motor to rotate, and cylindrical pins are arranged on the pin wheel eccentrically, so that when the pin wheel rotates to an appropriate position, the cylindrical pins slide into sliding grooves in a quartered cross wheel which is driven to rotate, a small gear is driven by a large gear coaxially arranged on the quartered cross wheel to rotate, and a sliding pin on the small gear is inserted into a pin groove to drive a rocker arm to swing back and forth. According to the mechanism, due to the structural special design, when the cylindrical pin slides out of the sliding groove in the quartered cross wheel, the pin wheel is in an idling state and cannot drive the quartered cross wheel to rotate, the deceleration motions are formed at the two swing ends during the rotation of the rocker arm, much reaction time can be provided during work-piece taking and putting, the work-piece grabbing accuracy is improved, and design requirements are achieved.
Description
Technical field
The utility model relates to a kind of feeder, is specifically related to a kind of cross wheel deceleration oscillating feed mechanism that can slow down at two ends.
Background technique
Mechanism is by being actively coupled the construction system forming by two or more members.By the difference of relative movement between each member of composition, mechanism can be divided into planar mechanism (as planar linkage, cylindrical gear mechanism etc.) and spatial mechanism's (as spatial linkage, worm-and-wheel gear etc.); Can be divided into low counter gear (as linkage mechanism etc.) and higher pair mechanism (as cam mechanism etc.) by kinematic pair classification; Can be divided into linkage mechanism, gear mechanism, oblique mechanism, ratchet mechanism etc. by structure characteristic; Can be divided at the uniform velocity and non-uniform rotation mechanism, straight-line motion mechanism, changement, intermittent motion mechanism etc. by the feature of changed motion or power; Can be divided into safety insurance mechanism, interlocking mechanism, escapement etc. by function.
Reciprocally swinging mechanism at the uniform velocity swings often in the process swinging, thereby how to realize, reduce the precision that swing speed can improve gripping workpiece at two ends be the problem facing at present.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of cross wheel deceleration oscillating feed mechanism that can slow down at two ends.
For achieving the above object, the technical solution of the utility model is: cross wheel deceleration oscillating feed mechanism, comprise support, on described support, be fixed with motor, on the output shaft of described motor, key connects a pin wheel, is symmetrically fixed with two straight pins on described pin wheel, is coaxially provided with a disk check plate on described pin wheel, described disk check plate comprises circular arc in two sections of external arc and two sections, and described external arc and interior circular arc are alternately arranged; On described support, be also hinged with a quartering cross wheel, described straight pin can coordinate in the chute that slips into quartering cross wheel, and described quartering cross wheel is provided with four arcs section, and the external arc on described four arcs section and disk check plate matches; On described quartering cross wheel, be coaxially provided with a gearwheel; On described support, be also provided with a rocking arm, one end of described rocking arm is provided with the jaw of gripping workpiece, and the other end of described rocking arm is hinged on support, and the middle part of described rocking arm offers a cotter way; On described support, be also hinged with a small gear, described small gear and gearwheel engagement, on described small gear, bias is provided with a sliding pin, and described sliding pin inserts in the cotter way of rocking arm.
While adopting technique scheme, rotate by driven by motor pin wheel, because bias on pin wheel is provided with straight pin, in the time that pin wheel turns to suitable position, straight pin slips in the chute on quartering cross wheel, now drive quartering cross wheel to rotate, by coaxially arranging on quartering cross wheel, the large gear turn the small gear rotates again afterwards, and the sliding pin on small gear inserts drive rocking arm in cotter way and does reciprocally swinging.Due to structural particular design, in the time that straight pin skids off the chute on quartering cross wheel, pin wheel is in idling conditions, can not drive quartering cross wheel to rotate, therefore, rocking arm can form retarded motion at the two ends that swing in the time rotating, and can in the time picking and placeing workpiece, have the more reaction time, the precision that improves grabbing workpiece, reaches designing requirement.
Further, described support vertically arranges, and described motor is arranged on a side of support, and described pin wheel, quartering cross wheel, small gear and rocking arm are arranged on the opposite side of support.Above-mentioned arrange can balance bracket both sides weight, avoid weight too to concentrate accelerated wear test.
Further, the rotating shaft of the rotating shaft of described pin wheel and quartering cross wheel is positioned on same level line.
Further, described support is provided with the block that the transition of restriction rocking arm is rotated.
Further, described block is provided with pressure transducer, and described pressure transducer connects the opening and closing device of workpiece discharge port by processor.By above-mentioned setting, can realize the automatic feeding function of swing arm.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model cross wheel deceleration oscillating feed mechanism for implementing example.
Embodiment
As shown in Figure 1, the utility model cross wheel deceleration oscillating feed mechanism, comprise vertical support, support is provided with motor, on the output shaft of motor, key connects a pin wheel 1, is symmetrically fixed with two straight pins 11 on pin wheel 1, on pin wheel 1, is connected with a disk check plate 2 with axle key, disk check plate 2 comprises circular arc in two sections of external arc and two sections, and external arc and interior circular arc are alternately arranged.On support, be also hinged with a quartering cross wheel 3, straight pin 11 can coordinate in the chute 31 that slips into quartering cross wheel 3, and quartering cross wheel 3 is provided with four arcs section, and the external arc on four arcs section and disk check plate 2 matches.On quartering cross wheel 3, connect a gearwheel 4 with axle key.On support, be also provided with a rocking arm 6, one end of rocking arm 6 is hinged on support, and the middle part of rocking arm 6 offers a cotter way 61.On support, be also hinged with a small gear 5, small gear 5 and gearwheel 4 engage, and on small gear 5, bias is provided with a sliding pin 51, and sliding pin 51 inserts in the cotter way 61 of rocking arm.The rotating shaft of the rotating shaft of pin wheel 1 and quartering cross wheel 3 is positioned on same level line.Support is provided with the block 7 that 6 transition of restriction rocking arm are rotated.Block 7 is provided with pressure transducer, and described pressure transducer connects the opening and closing device of workpiece discharge port by processor.By above-mentioned setting, can realize the automatic feeding function of swing arm 6.
When use, rotate by driven by motor pin wheel 1, because bias on pin wheel 1 is provided with straight pin 11, in the time that pin wheel 1 turns to suitable position, straight pin 11 slips in the chute 31 on quartering cross wheel 3, now drive quartering cross wheel 3 to rotate, drive small gear 5 to rotate again afterwards by the coaxial gearwheel 4 arranging on quartering cross wheel 3, the sliding pin 51 on small gear 5 inserts the interior drive rocking arm 6 of cotter way 61 and does reciprocally swinging.Due to structural particular design, in the time that straight pin 11 skids off the chute 31 on quartering cross wheel 3, pin wheel 1 is in idling conditions, can not drive quartering cross wheel 3 to rotate, therefore, rocking arm 6 can form retarded motion at the two ends that swing in the time rotating, and can in the time picking and placeing workpiece 8, have the more reaction time, the precision that improves grabbing workpiece 8, reaches designing requirement.
