Abstract
The utility model discloses a wedge rod mechanism of a hydraulic type self-aligning fixing device. The wedge rod mechanism of the hydraulic type self-aligning fixing device comprises a clamp body, a left clamping claw, a right clamping claw, a horizontal plate, a screw, a sleeve and a wedge-shaped rod, wherein the left clamping claw and the right clamping claw are used for clamping a workpiece, the screw slides vertically in the clamp body, the sleeve is arranged on the screw, the wedge-shaped rod serves as a force applying device, the end portion of each clamping claw is connected on the clamp body in a hinged mode, a pin shaft is arranged in the middle of each clamping claw, two oblique strip-shaped holes are symmetrically formed in the horizontal plate, the pin shafts slide in the strip-shaped holes, the horizontal plate is connected on the sleeve, a reset spring is arranged between the sleeve and the screw, one end of the spring is connected with the sleeve, the other end of the spring is connected with the screw, a wedge-shaped hole is formed in the screw, the wedge-shaped rod in sliding connection with the wedge-shaped hole is arranged in the wedge-shaped hole, and the wedge-shaped rod is driven by hydraulic pressure. According to the wedge rod mechanism of the hydraulic type self-aligning fixing device, the wedge-shaped rod is driven by the hydraulic pressure to move to the left, the screw, the sleeve and the horizontal plate move downwards under the action of a wedge-shaped surface, the clamping claws clamp the workpiece under the action of the strip-shaped holes tilting upwards from inside to outside, and then the workpiece is clamped well and prevented from moving.
Description
Technical field
The utility model belongs to the technical field of anchor clamps, relates in particular to a kind of tapered bar mechanism of fluid pressure type automatic aligning fixture.
Background technology
The swing anchor clamps are widely used in the manufacturing operation, and the swing by bare terminal end comes the loading and unloading workpiece.In existing clamp assembly, workpiece is fixed in place by the coupling between himself physical form and the bare terminal end correspondingly-shaped, and in the operation of reality, workpiece of a great variety, the size shape of workpiece also can change, and as not adopting the clamp assembly that is complementary with it, workpiece may be shifted with respect to bare terminal end, cause the final position of workpiece inaccurate, thereby workpiece correctly can't be installed to correct position.
The utility model content
The technical problems to be solved in the utility model provides a kind of swing hold down gag, and holding workpiece prevents its displacement preferably.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of tapered bar mechanism of fluid pressure type automatic aligning fixture, comprise chuck body, a left side that is used for clamping work pieces, right jaw, transverse slat, the screw rod that in chuck body, slides up and down, be located on the screw rod sleeve pipe and as the tapered shaft of force application apparatus, the end of described jaw is hinged on the chuck body, the middle part of jaw is provided with bearing pin, be arranged with two oblique bar holes on the transverse slat, bearing pin slides in bar hole, transverse slat is connected on the sleeve pipe, be provided with back-moving spring between sleeve pipe and the screw rod, one end of spring is connected with sleeve pipe, the other end is connected with screw rod, screw rod is provided with wedged hole, is provided with in the wedged hole and itself and the tapered shaft that is slidingly connected, and described tapered shaft is by hydraulic-driven.
Compared with prior art, advantage of the present utility model is: when needing clamping work pieces, tapered shaft promotes left under the driving of hydraulic pressure, and because of the effect of lozenges, screw rod and sleeve pipe move downward, the drive transverse slat pulls down, for being inclined upwardly from inside to outside, jaw can inwardly be swung under the effect of bar hole as the bar hole on the transverse slat, thus clamping work pieces, holding workpiece prevents its displacement preferably; In the time of need unclamping workpiece, tapered shaft is not applied external force, sleeve pipe can float under the effect of back-moving spring voluntarily, transverse slat also can move upward, for being inclined upwardly from inside to outside, jaw can outwards be swung under the effect of bar hole, thereby unclamps workpiece as the bar hole on the transverse slat.
Description of drawings
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:
Fig. 1 is the structural representation of the tapered bar mechanism for implementing example of the utility model fluid pressure type automatic aligning fixture.
The specific embodiment
As shown in Figure 1, the tapered bar mechanism of a kind of fluid pressure type automatic aligning fixture in the present embodiment, comprise chuck body, a left side that is used for clamping work pieces, right jaw 5, transverse slat 4, the screw rod 2 that in chuck body, slides up and down, be located on the screw rod 2 sleeve pipe 3 and as the tapered shaft 1 of force application apparatus, the end of described jaw 5 is hinged on the chuck body, the middle part of jaw 5 is provided with bearing pin, be arranged with two oblique bar holes on the transverse slat 4, bearing pin slides in bar hole, transverse slat 4 is connected on the sleeve pipe 3, be provided with back-moving spring 6 between sleeve pipe 3 and the screw rod 2, one end of back-moving spring 6 is connected with sleeve pipe 3, the other end is connected with screw rod 2, screw rod 2 is provided with wedged hole, is provided with the tapered shaft 1 that is slidingly connected with it in the wedged hole, and described tapered shaft 1 is by hydraulic-driven.
When needing clamping work pieces, tapered shaft 1 promotes left under the driving of hydraulic pressure, effect because of lozenges, screw rod 2 and sleeve pipe 3 move downward, drive transverse slat 4 and pull down, as the bar hole on the transverse slat 4 for being inclined upwardly from inside to outside, jaw 5 can inwardly be swung under the effect of bar hole, thereby clamping work pieces, holding workpiece prevents its displacement preferably; In the time of need unclamping workpiece, tapered shaft 1 is not applied external force, sleeve pipe 3 can float under the effect of back-moving spring 6 voluntarily, transverse slat 4 also can move upward, for being inclined upwardly from inside to outside, jaw 5 can outwards be swung under the effect of bar hole, thereby unclamps workpiece as the bar hole on the transverse slat 4.
For a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement, these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
