Description
Technical field
The present invention relates to a kind of manual quick clamp device, it is adaptable to when CNC milling machine and common iron bed milled part, need the workplace of quick positioning and clamping.
Background technology
At present, still workpiece pressing is carried out with pressing plate by tightening screw when CNC milling machine and plain-milling machine milled part. process part screw to be unclamped and pull down pressing plate, soldering part, sometimes Clamp blocks it is also required to. also it is to use this method of pressing plate compressing component, this method clamping time is long, production efficiency is low, especially the biggest on production efficiency impact when batch production.
Utility model summary of the invention
The technical problem to be solved in the present invention is to provide a kind of manual quick clamp device, transmits the force to force transmission shaft by cam handle, and then drives two side guides that workpiece carries out clamping, not only can two parts of clamping simultaneously, reduce the clamping time, and there is self-locking performance.
For solving problem above, the concrete technical scheme of the present invention is as follows: a kind of manual quick clamp device, positioning support both sides are equipped with pressing plate, it is connected with cam handle on one side guide, opposite side pressing plate is provided with locking device, positioning support is sequentially provided with U-shaped link, extension spring and the force transmission shaft of symmetrical structure from top to bottom along its center line, and force transmission shaft two ends are all fixing with two side guides with cam handle and locking device point cantact, extension spring and U-shaped link two ends respectively to be connected.Making to move through force transmission shaft by oscillating cam handle and pass to pressing plate, extension spring drives platen clamp workpiece, completes workpiece location, shortens the Operational preparation time, improves production efficiency.
Preferably, the center line of described U-shaped link, extension spring and force transmission shaft all with the central axis of positioning support, the upper surface of positioning support is provided with two workbench, and two workbench are symmetrical about the center line of positioning support.It is provided with two workbench on same positioning support, a cam handle can be swung and complete the clamping to two workpiece, improve operating efficiency.
Preferably, described cam handle is flexibly connected by bearing pin with pressing plate.It is easy to cam handle rotate relative to pressing plate.
Preferably, described locking device is made up of locking nut and adjustment screw, and the ailhead axial line adjusting screw overlaps with the axial line of force transmission shaft.
Preferably, the upper surface of described pressing plate and the peak of positioning support are at same plane.
What the present invention brought has the beneficial effect that cam handle makes cam-type, make swift to operate laborsaving, add the thrust of pressing plate, can self-locking, safe and reliable, positioning support is provided with force transmission shaft, can clamp two workpiece with one-time positioning, one extension spring with force transmission shaft Parallel Design, when processing workpiece, unclamp cam handle pressing plate can automatically open up, this device can realize clamping, location once completes, and reduces the clamping time, improves production efficiency, safe and reliable, it is adaptable to the production of parts batch.
Accompanying drawing explanation
Fig. 1 is the structural representation of manual quick clamp device.
Wherein, 1-cam handle, 2-bearing pin, 4-pressing plate, 5-U type link, 6-positioning support, 8-extension spring, 9-force transmission shaft, 10-locking nut, 11-adjusts screw, 12-workbench.
Detailed description of the invention
A kind of manual quick clamp device, positioning support 6 both sides are equipped with pressing plate, it is connected with cam handle 1 on one side guide 4, opposite side pressing plate 4 is provided with locking device, positioning support 6 is sequentially provided with the U-shaped link 5 of symmetrical structure, extension spring 8 and force transmission shaft 9 from top to bottom along its center line, force transmission shaft 9 two ends are all fixing with two side guides 4 with cam handle 1 and locking device point cantact, extension spring 8 and U-shaped link 5 two ends respectively to be connected.Making to move through force transmission shaft 9 by oscillating cam handle 1 and pass to pressing plate 4, extension spring 8 band dynamic pressure plate 4 clamps workpiece, completes workpiece location, shortens the Operational preparation time, improves production efficiency.
Preferably, the center line of described U-shaped link 5, extension spring 8 and force transmission shaft 9 all with the central axis of positioning support 6, the upper surface of positioning support 6 is provided with two workbench 12, and two workbench 12 are symmetrical about the center line of positioning support 6.It is provided with two workbench 12 on same positioning support 6, a cam handle 1 can be swung and complete the clamping to two workpiece, improve operating efficiency.
Preferably, described cam handle 1 is flexibly connected by bearing pin with pressing plate 4.It is easy to cam handle 1 and does oscillating motion relative to pressing plate 4.
Preferably, described locking device is made up of locking nut 10 and adjustment screw 11, and the ailhead axial line adjusting screw 11 overlaps with the axial line of force transmission shaft 9.
Preferably, the upper surface of described pressing plate 4 and the peak of positioning support 6 are at same plane.
The course of work:
The workpiece of required clamping is placed on workbench upper surface, rotate cam handle 1, cam handle 1 transmits the force to force transmission shaft 9, and force transmission shaft 9 transmits the force to pressing plate 4, and under the effect of U-shaped link 5, two side guides 4 are simultaneously to Workpiece clamping, complete Workpiece clamping location, then workpiece being carried out milling, when clamped workpiece completes to add man-hour, opposite direction rotates cam handle 1, two side guides 4 automatically open up pressing plate 4 under the elastic force of extension spring 8, take out workpiece.
When accessory size changes and can't clip part, regulation adjusts screw 11 and arrives correct position, screws locking nut 10 and prevents adjustment screw 11 from loosening.
