The connection rod of the pressing head is connected with the end, close to the supporting base, of the rack. The workpiece pressing mechanism is large in clamping force, and workpieces can be stably clamped.
Description
Technical field
The present invention relates to a kind of clamping device, be specifically related to a kind of Work-sheet pressing mechanism.
Background technology
In machine tooling, after usually needing to use clamp system that workpiece is fixing, then carry out follow-up processing, so clamp system is widely used in work pieces process field.
Clamping device all comprises power source and clamp system usually, and the tooth bar clamping device that existing gear coordinates is normally using motor as power source, and rotated by motor driven gear, gear is with again carry-over bar to move, thus realizes the action clamping and unclamp workpiece.But in the clamping device of said structure, the moment of pinion rotation is little, so the power that gear is applied on tooth bar is less, may occur during holding workpiece clamping not tight problem.
Summary of the invention
For the defect that above-mentioned prior art exists, the object of the present invention is to provide a kind of clamping force large, the Work-sheet pressing mechanism that workpiece stably can be clamped.
For achieving the above object, technical scheme of the present invention is:
Work-sheet pressing mechanism, comprise support and tooth bar, wherein, also be provided with the hold-down head of the conical gear of band reinforcement handle, oscillating cylinder and band connecting rod, described support is provided with chute, tooth bar is arranged in chute, described conical gear home position and support are rotationally connected, and conical gear engages with tooth bar, piston rod and the reinforcement handle of described oscillating cylinder are hinged, oscillating cylinder to swing with support away from piston rod one end and is connected, and the position that described support is relative with tooth bar one end is provided with supporting base, and the connecting rod of described hold-down head is connected with tooth bar one end near supporting base.
When adopting technique scheme, because conical gear home position and support are rotationally connected, and conical gear engages with tooth bar, when controlling oscillating cylinder air inlet, the piston rod of oscillating cylinder stretches out or shrinks, the piston rod of oscillating cylinder is with hinged with reinforcement handle, so piston rod can drive reinforcement handle, such conical gear rotates around its home position, thus band carry-over bar moves in chute, the position relative with tooth bar one end due to support is provided with supporting base, and the connecting rod of hold-down head is connected with tooth bar one end near supporting base, so tooth bar can drive hold-down head to move, hold-down head is clamping work pieces when supporting base, away from supporting base for unclamping workpiece.The present invention adopts the conical gear of band reinforcement handle to coordinate with tooth bar, reinforcement handle one end of conical gear and the piston rod of oscillating cylinder hinged, so just can increase the moment that conical gear rotates, the power that conical gear is applied on tooth bar also increases thereupon, during rack drives hold-down head clamping work pieces, the clamping force be applied on workpiece is larger, so clamping work pieces is more stable.
Further, described tooth bar side is provided with the lock-screw locking connecting rod.By lock-screw, the mode that connecting rod is connected with tooth bar is convenient to detachable maintaining.
Further, described hold-down head holding workpiece side is provided with rubber blanket.During hold-down head clamping work pieces, rubber blanket and absorption surface, like this would not disfiguring workpiece surface.
Further, described support is provided with the caging bolt coordinating conical gear reinforcement handle side.Caging bolt can limit the maximum displacement of tooth bar, and the hold-down head being connected to tooth bar one end so just can be prevented workpiece compressive strain.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of Work-sheet pressing mechanism embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises:.
As shown in Figure 1, Work-sheet pressing mechanism, comprise support 1 and tooth bar 5, wherein, also be provided with the conical gear 4 of band reinforcement handle 3, the hold-down head 7 of oscillating cylinder 2 and band connecting rod 6, support 1 is provided with chute, tooth bar 5 is arranged in chute, conical gear 4 home position and support 1 are rotationally connected, and conical gear 4 engages with tooth bar 5, the piston rod 21 of oscillating cylinder 2 is hinged with reinforcement handle 3, as shown in Figure 1, reinforcement handle 3 is provided with multiple hinge hole, so just different hinge holes can be selected, thus change moment, oscillating cylinder 2 to swing with support 1 away from piston rod 21 one end and is connected, the position that support 1 is relative with tooth bar 5 one end is provided with supporting base 8, the connecting rod 6 of hold-down head 7 is connected with tooth bar 5 one end near supporting base 8.
In the present embodiment, tooth bar 5 side is provided with the lock-screw 11 locking connecting rod 6.By lock-screw 11, the mode that connecting rod 6 is connected with tooth bar 5 is convenient to detachable maintaining.
Hold-down head 7 holding workpiece 12 side is provided with rubber blanket 9.During hold-down head 7 clamping work pieces 12, rubber blanket 9 contacts with workpiece 12, like this would not disfiguring workpiece 12 surface.
Support 1 is provided with the caging bolt 10 coordinating conical gear 4 reinforcement handle 3 side.Caging bolt 10 can limit the maximum displacement of tooth bar 5, and the hold-down head 7 being connected to tooth bar 5 one end so just can be prevented workpiece 12 compressive strain.
Specific works principle:
As shown in Figure 1, because conical gear 4 home position and support 1 are rotationally connected, and conical gear 4 engages with tooth bar 5, when controlling oscillating cylinder 2 air inlet, the piston rod 21 of oscillating cylinder 2 stretches out or shrinks, the piston rod 21 of oscillating cylinder 2 is with hinged with reinforcement handle 3, so piston rod 21 can drive reinforcement handle 3, such conical gear 4 rotates around its home position, thus band carry-over bar 5 moves in chute, the position relative with tooth bar 5 one end due to support 1 is provided with supporting base 8, and the connecting rod 6 of hold-down head 7 is connected with tooth bar 5 one end near supporting base 8, so tooth bar 5 can drive hold-down head 7 to move, hold-down head 7 is clamping work pieces 12 when supporting base 8, away from supporting base 8 for unclamping workpiece 12.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
