Abstract
The invention discloses a rotary synchronous clamping device. Under the driving of a motor, a rotary disk swings back and forth, so that a rotary rod fixed to the rotary disk is driven to swing back and forth. Due to the fact that the rotary rod is hinged to a connecting rod and the sliding end of the connecting rod is fixed into a sliding groove of a pressing rod, the pressing rod also swings back and forth under the driving of the connecting rod, the swing angle of the pressing rod is larger than the swing angle of the rotary rod, and a workpiece can be clamped by a driving chuck conveniently. Besides, due to the arrangement of a driving belt pulley and a driven belt pulley, the driving belt pulley and the driven belt pulley synchronously rotate, a driven chuck at the tail end of a driven rack and the driving chuck on the pressing rod can synchronously clamp the workpiece, and the workpiece can be clamped in two directions synchronously.

Technical field
The present invention relates to a kind of automation fixture of machining, be specifically related to a kind of swinging 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 swinging 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: swinging synchronous clamping device, comprise support, and on described support, be fixed with a turning motor, on the output shaft of described turning motor, key is connected with a rotary disk, has fixed a bull stick on described rotary disk; The free end of described bull stick is fixedly connected with a connecting rod, and described connecting rod is divided into hinged end and sliding end; On described support, be also provided with a holder, be hinged with a depression bar on described holder, the free end of depression bar is fixed with a drive dog, and the stage casing of described depression bar offers a chute, and the sliding end of described connecting rod is fixed in chute; On described rotary disk, 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, 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, under the drive of motor, rotary disk reciprocally swinging, drive is fixed on the bull stick reciprocally swinging on rotary disk, and due to bull stick and rod hinge connection, the sliding end of connecting rod is fixed in the chute of depression bar simultaneously, like this under the drive of connecting rod, depression bar is also done reciprocal swing, and the angle that depression bar swings can be greater than the angle that bull stick swings, and facilitates drive dog clamping work pieces.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, the stage casing of described connecting rod is provided with elasticity bolt, and described elasticity bolt is the screwed pipe running through, and the thread rotary orientation at described screwed pipe two ends is contrary; Described connecting rod comprises two threaded rods, and described two threaded rods are threaded in respectively the two ends of screwed pipe.By elasticity bolt is set, the one, can be according to the length of actual user demand regulating connecting rod, and then regulate the amplitude of fluctuation of depression bar.The 2nd, the connecting rod of segmentation is convenient to processing more, is in use also convenient to safeguard and change.
Further, described support is provided with the block of restriction bull stick swing position.
Further, described block is provided with pressure sensor, and described pressure sensor connects the control device of turning motor by processor.
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 swinging synchronous clamping device embodiment of the present invention.
The specific embodiment
As shown in Figure 1, swinging synchronous clamping device of the present invention, comprises support, is fixed with a turning motor on described support, and on the output shaft of described turning motor, key is connected with a rotary disk 1, has fixed a bull stick 2 on described rotary disk 1; The free end of described bull stick 2 is fixedly connected with a connecting rod 3, and described connecting rod 3 is divided into hinged end and sliding end; On described support, be also provided with a holder 4, be hinged with a depression bar 5 on described holder 4, the free end of depression bar 5 is fixed with a drive dog 51, and the stage casing of described depression bar 5 offers a chute 52, and the sliding end of described connecting rod 3 is fixed in chute 52; On described rotary disk 1, be also coaxially provided with a driving pulley 6, be also hinged with a driven pulley 61 on described support, described driving pulley 6 is connected by belt 62 with driven pulley 61, is coaxially provided with a driven gear 7 on described driven pulley 61; On described support, be also provided with the driven tooth bar 71 of a level, 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 72 coordinating with drive dog 51.The stage casing of described connecting rod 3 is provided with elasticity bolt, and described elasticity bolt is the screwed pipe running through, and the thread rotary orientation at described screwed pipe two ends is contrary; Described connecting rod 3 comprises two threaded rods, and described two threaded rods are threaded in respectively the two ends of screwed pipe.By elasticity bolt is set, the one, can be according to the length of actual user demand regulating connecting rod 3, and then regulate the amplitude of fluctuation of depression bar 5.The 2nd, the connecting rod 3 of segmentation is convenient to processing more, is in use also convenient to safeguard and change.Described support is provided with the block 21 of restriction bull stick 2 swing position.Described block 21 is provided with pressure sensor, and described pressure sensor connects the control device of turning motor by processor.
