Abstract
The invention discloses a variable-speed synchronous clamp device. A motor drives a drive gear to drive a transmission gear to rotate, wherein the transmission gear is engaged with the drive gear; because the transmission gear is eccentrically provided with a transmission roller, and the transmission roller is inserted in a chute formed in the middle section of a press rod, in the rotating process of the transmission gear, the transmission gear is capable of driving the press rod to swing around the hinge point through the transmission roller, and moreover, the transmission roller is mounted eccentrically, so that two ends of the press rod swing quickly while the middle swing slowly, and the swinging speed can be regulated according to the workpiece to be clamped. In addition, because the drive gear is coaxially provided with a drive pulley, and the drive pulley and a driven pulley rotate synchronously, a following chuck at the end of the driven gear and a drive chuck on the press rod are capable of synchronously clamping the workpiece, and the bidirectional synchronous clamp for the workpiece is realized.
Description
Technical field
The present invention relates to a kind of automation fixture of machining, be specifically related to a kind of speed changing type synchronous clamping device.
Background technology
Fixture is a kind of common parts in machining, is generally to be coordinated workpiece is clamped by moving fixture block and clamp piece.But under special service condition, need two fixture blocks all can move, and will keep two fixture blocks to be synchronized with the movement, realize synchronous clamping.
Summary of the invention
The object of the present invention is to provide a kind of speed changing type synchronous clamping device, by simple structure, realize the synchronous clamping function to workpiece.
For achieving the above object, technical scheme of the present invention is: speed changing type synchronous clamping device, comprise support, and on described support, be fixed with a motor, in the rotating shaft of described motor, key is connected with a driving gear; On described driving gear, be engaged with a travelling gear, on described travelling gear, bias is provided with a drive balls; On described support, be also hinged with a depression bar, described depression bar free end is provided with drive dog, and the stage casing of described depression bar offers a chute, and described drive balls is fixed in chute; On described driving gear, be also coaxially provided with a driving pulley, be also hinged with a driven pulley on described support, described driving pulley is connected by belt with driven pulley, is coaxially provided with a driven gear on described driven pulley; On described support, be also provided with the driven tooth bar of a level, down, described driven gear and driven tooth bar mesh the flank of tooth of described driven tooth bar, and the end of described driven tooth bar is provided with a servo-actuated chuck coordinating with drive dog.
While adopting technique scheme, under driven by motor, driving gear drives with the travelling gear of its engagement and rotates, due to eccentric setting on travelling gear a drive balls, and drive balls has been inserted in the chute in depression bar stage casing, so just make travelling gear can drive depression bar to swing around pin joint by drive balls in the process of rotating.And because drive balls is eccentric setting, so the swing speed of depression bar occur two ends fast in the middle of slow situation, the workpiece that its swing speed can be clamped according to actual needs regulates; In addition, owing to being coaxially provided with a driving pulley on driving gear, by the setting of driving pulley and driven pulley, both synchronously rotate, make the servo-actuated chuck of driven tooth bar end and the drive dog on depression bar can synchronous clamping workpiece, realize the bi-directional synchronization of workpiece is clamped.
Further, on described support, be also provided with the block of restriction depression bar amplitude of fluctuation.By the amplitude of fluctuation that block can manual control depression bar is set, and then realistic use needs.
Further, described block is provided with pressure sensor, and described pressure sensor connects the control device of motor by processor.By pressure sensor, collect signal, can pass through the action of processor automatic control motor, realization automatically moves back and forth.
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 speed changing type synchronous clamping device embodiment of the present invention.
The specific embodiment
As shown in Figure 1, speed changing type synchronous clamping device of the present invention, comprises support, is fixed with a motor on described support, and in the rotating shaft of described motor, key is connected with a driving gear 1; On described driving gear 1, be engaged with a travelling gear 2, on described travelling gear 2, bias is provided with a drive balls 21; On described support, be also hinged with a depression bar 3, described depression bar 3 free ends are provided with drive dog 31, and the stage casing of described depression bar 3 offers a chute 32, and described drive balls 21 is fixed in chute 32; On described driving gear 1, be also coaxially provided with a driving pulley 4, be also hinged with a driven pulley 41 on described support, described driving pulley 4 is connected by belt 42 with driven pulley 41, is coaxially provided with a driven gear 5 on described driven pulley 41; On described support, be also provided with the driven tooth bar 6 of a level, down, described driven gear 5 and driven tooth bar 6 mesh the flank of tooth of described driven tooth bar 6, and the end of described driven tooth bar 6 is provided with a servo-actuated chuck 61 coordinating with drive dog 31.On described support, be also provided with the block 7 of restriction depression bar 3 amplitudes of fluctuation.By the amplitude of fluctuation that block 7 can manual control depression bar 3 is set, and then realistic use needs.Described block 7 is provided with pressure sensor, and described pressure sensor connects the control device of motor by processor.By pressure sensor, collect signal, can pass through the action of processor automatic control motor, realization automatically moves back and forth.
During use, under driven by motor, driving gear 1 drives with the travelling gear 2 of its engagement and rotates, due to eccentric setting on travelling gear 2 drive balls 21, and drive balls 21 has been inserted in the chute 32 in depression bar 3 stage casings, so just make travelling gear 2 can drive depression bar 3 to swing around pin joint by drive balls 21 in the process of rotating.And because drive balls 21 is eccentric settings, so the swing speed of depression bar 3 occur two ends fast in the middle of slow situation, the workpiece that its swing speed can be clamped according to actual needs regulates; In addition, owing to being coaxially provided with a driving pulley 4 on driving gear 1, by the setting of driving pulley 4 and driven pulley 41, both synchronously rotate, make the servo-actuated chuck 61 of driven tooth bar 6 ends and the drive dog 31 on depression bar 3 can synchronous clamping workpiece, realize the bi-directional synchronization of workpiece is clamped.
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.
