Description
Technical field
The present invention relates to a kind of clamping device, be specifically related to a kind of pneumatic cam clamping device.
Background technology
In machine tooling, after conventionally need to using clamp mechanism that workpiece is fixing, then carry out follow-up processing, so clamping device is widely used in workpiece manufacture field, and existing clamp mechanism shortcoming is: 1. the action of pressing plate holding workpiece is slower; 2. during holding workpiece, force side need to continue the application of force.So cause working (machining) efficiency lower.
Summary of the invention
The defect existing for above-mentioned prior art, the object of the present invention is to provide a kind of pneumatic cam clamping device, and this clamp mechanism be take cylinder as power source, and holding action is fast, and after pressing plate clamping work pieces, cam self-locking, so improved working (machining) efficiency.
For achieving the above object, technical scheme of the present invention is: pneumatic cam clamping device, comprise support and with the pressing plate of clamping head, described support is provided with brace table, described pressing plate middle part is articulated with brace table upper end, wherein, also be provided with driving mechanism and resetting-mechanism, described driving mechanism comprises the cylinder of vertical setting, cam and cam lever, described support pressing plate clamping head far away one end is provided with supporting base, described cam is rotationally connected with on supporting base, piston rod and the cam lever of described cylinder are hinged, the lower surface of described upper cam surface and pressing plate clamping head far away one end offsets, described resetting-mechanism comprises release link and back-moving spring, and described release link is positioned at the nearly clamping head of pressing plate one end, and described pressing plate is provided with the hole that coordinates release link to stretch into, and described back-moving spring is sheathed in release link.
While adopting technique scheme, workpiece is positioned on the support of pressing plate clamping head below, control cylinder air inlet, the piston rod driving cam bar of cylinder, now cam lever band moving cam rotates, cam contacts side radius with pressing plate increases, now, cam applies component upwards to pressing plate clamping head far away one end, so pressing plate clamping head far away one end upwards swings, because pressing plate middle part is articulated with on brace table, so pressing plate clamping head one end bottom, by piece-holder, by after piece-holder, cam can be realized self-locking, prevents that piece-holder is unstable.The present invention is by cylinder as power source, and holding action is fast, and after pressing plate clamping work pieces, cam self-locking, so improved working (machining) efficiency.
Further, described pressing plate middle part is provided with strip hole, and hinged by strip hole and brace table upper end, and the position-adjustable of pressing plate, to coordinate better cam.
Further, described cylinder lower end is provided with base, and cylinder lower end and base hinged, the piston rod of described cylinder, in the upper process pushing away with drop-down piston rod, can swing, thereby can shock absorbing power.
Further, the surface that described pressing plate contacts with cam is provided with wearing layer, and pressing plate clamping head far away one end contacts with cam and friction continually, and is set the service life that wearing layer can extend pressing plate.
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 the pneumatic cam clamping device of the present invention embodiment.
The specific embodiment
As shown in Figure 1, a kind of pneumatic cam 5 clamping devices, comprise support 1 and with the pressing plate 7 of clamping head, support 1 is provided with brace table 6, pressing plate 7 middle parts are articulated with brace table 6 upper ends, wherein, also be provided with driving mechanism and resetting-mechanism, driving mechanism comprises cylinder 2, cam 5 and the cam lever of vertical setting, support 1 pressing plate far away 7 clamping head one end are provided with supporting base 4, cam 5 is rotationally connected with on supporting base 4, and the piston rod 3 of cylinder 2 is hinged with cam lever, and the lower surface of cam 5 upper surfaces and pressing plate 7 clamping head far away one end offsets; Resetting-mechanism comprises release link 9 and back-moving spring 10, and release link 9 is positioned at pressing plate 7 nearly clamping head one end, and pressing plate 7 is provided with the hole that coordinates release link 9 to stretch into, and back-moving spring 10 is sheathed in release link 9.
In the present embodiment, pressing plate 7 middle parts are provided with strip hole 71, and hinged by strip hole 71 and brace table 6 upper ends, and the position-adjustable of pressing plate 7, to coordinate better cam 5.Cylinder 2 lower ends are provided with base, and cylinder 2 lower ends and base hinged, the piston rod 3 of cylinder 2, in the upper process pushing away with drop-down piston rod 3, can swing, thereby can shock absorbing power.Pressing plate 7 is provided with wearing layer with the surface that cam 5 contacts, and pressing plate 7 clamping head far away one end contact with cam 5 and friction continually, and is set the service life that wearing layer can extend pressing plate 7.
Specific works flow process:
As shown in Figure 1, be illustrated as pressing plate 7 and unclamp workpiece 8 states.Workpiece 8 is positioned on the support 1 under pressing plate 7 clamping heads, Compressed Gas is entered in cylinder 2 lower ends, the piston rod 3 of cylinder 2 is actuating cam bar upwards, cam 5 rotates to be dynamically connected and a little clockwise rotates, cam 5 contacts side radius with pressing plate 7 increases, now, cam 5 applies component upwards to pressing plate 7 clamping head far away one end, so pressing plate 7 clamping head far away one end upwards swing, because pressing plate 7 middle parts are articulated with on brace table 6, so pressing plate 7 clamping head one end bottoms, thereby by workpiece 8 clampings, the back-moving spring 10 that closely clamps first side is compressed.Cylinder 2 upper end air inlets, the piston rod 3 of cylinder 2 upwards pulls cam lever, cam 5 rotates to be dynamically connected and a little rotates counterclockwise, cam 5 reduces with the radius that pressing plate 7 contacts a side, both do not have interaction force, the nearly back-moving spring 10 that clamps first side upwards promotes the first side of pressing plate 7 nearly clamping, and pressing plate 7, around the pin joint counter-clockwise swing at middle part, unclamps workpiece 8.
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.
