Abstract
The invention discloses a crank synchronous swing type clamping device. A gear is driven by a motor to rotate, due to the facts that a connecting plate is fixed to the gear, and a drive roller at one end of the connecting plate is inserted into a sliding groove of a pressure rod, when the gear rotates, the connecting plate and the pressure rod form a crank sliding block mechanism, due to the design, linear motion of the motor can be converted into reciprocating motion of the pressure rod, and a workpiece can be clamped through a driving chuck on the pressure rod. In addition, a driving pulley and a driven pulley are arranged and rotate synchronously, so that a follow-up chuck at the tail end of a driven gear rack and the driving chuck on the pressure rod can synchronously clamp the workpiece, and the workpiece is clamped synchronously in a bi-directional mode.
Description
Technical field
The present invention relates to a kind of automation fixture of machining, be specifically related to a kind of crank synchronous oscillating 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 crank synchronous oscillating clamping device, by simple structure, realize the synchronous clamping function to workpiece.
For achieving the above object, technical scheme of the present invention is: crank synchronous oscillating clamping device, comprise support, on described support, be fixed with motor, in the rotating shaft of described motor, key is connected with a gear, on described gear, be fixed with a connecting plate, the free end of described connecting plate is fixed with drive balls, is engaged with a tooth bar on described gear; On described support, be also hinged with a depression bar, the stage casing of described depression bar offers chute, and described drive balls is inserted in chute, and the other end of depression bar is fixed with a drive dog; On described 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 a vertical driven tooth bar, described driven gear and the engagement of driven tooth bar, the end of described driven tooth bar is provided with a servo-actuated chuck coordinating with drive dog.
While adopting technique scheme, by motor driven gear, rotate, owing to having fixed connecting plate on gear, and the drive balls of connecting plate one end has been inserted in the chute of depression bar, when gear rotates, connecting plate and depression bar form slider-crank mechanism, and such design can be converted to the rectilinear motion of motor the reciprocally swinging of depression bar, can workpiece be clamped by the drive dog on depression bar.In addition, due to by the setting of driving pulley and driven pulley, both synchronously rotate, and 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 that restriction tooth bar moves.By block is set, can avoid tooth bar to deviate from support under the effect of inertia.
Further, described block is provided with pressure sensor, and described pressure sensor connects the control device of motor by processor.Above-mentioned setting can be controlled and be sent signal by pressure sensor, and then the switching of automatic control motor and turning to.
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 crank synchronous oscillating clamping device embodiment of the present invention.
The specific embodiment
As shown in Figure 1, crank synchronous oscillating clamping device of the present invention, comprise support, on described support, be fixed with motor, in the rotating shaft of described motor, key is connected with a gear 1, on described gear 1, be fixed with a connecting plate 2, the free end of described connecting plate 2 is fixed with drive balls 21, is engaged with a tooth bar 11 on described gear 1; On described support, be also hinged with a depression bar 3, the stage casing of described depression bar 3 offers chute 31, and described drive balls 21 is inserted in chute 31, and the other end of depression bar 3 is fixed with a drive dog 4; On described gear 1, be also coaxially provided with a driving pulley 5, be also hinged with a driven pulley 51 on described support, described driving pulley 5 is connected by belt 52 with driven pulley 51, is coaxially provided with a driven gear 7 on described driven pulley 51; On described support, be also provided with a vertical driven tooth bar 71, described driven gear 7 and 71 engagements of driven tooth bar, the end of described driven tooth bar 71 is provided with a servo-actuated chuck 41 coordinating with drive dog 4.On support, be also provided with the block 8 that restriction tooth bar 11 moves.By block 8 is set, can avoid tooth bar 11 to deviate from support under the effect of inertia.Described block 8 is provided with pressure sensor, and described pressure sensor connects the control device of motor by processor.Above-mentioned setting can be controlled and be sent signal by pressure sensor, and then the switching of automatic control motor and turning to.
During use, by motor driven gear 1, rotate, owing to having fixed connecting plate 2 on gear 1, and the drive balls 21 of connecting plate 2 one end has been inserted in the chute 31 of depression bar 3, when gear 1 rotates, connecting plate 2 and depression bar 3 form slider-crank mechanism, and such design can be converted to the rectilinear motion of motor the reciprocally swinging of depression bar 3, can clamp by 4 pairs of workpiece of the drive dog on depression bar 3.In addition, due to by the setting of driving pulley 5 and driven pulley 51, both synchronously rotate, and make the servo-actuated chuck 41 of driven tooth bar 7 ends and the drive dog 4 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.
