Abstract
The invention discloses a wedge rod mechanism of a hydraulic type automatic aligning fixing device. The wedge rod mechanism comprises a clamp body, left and right clamping jaws, a transverse board, a threaded rod, a sleeve and a wedge-shaped rod, the left and right clamping jaws are used for clamping a workpiece, the threaded rod can vertically slide in the clamp body, the sleeve is arranged on the threaded rod, the wedge-shaped rod serves as a force application device, ends of the clamping jaws are hinged with the clamp body, pin shafts are arranged in the middles of the clamping jaws, two inclined strip-shaped holes are symmetrically arranged on the transverse board, the pin shafts slide in the strip-shaped holes, the transverse board is connected with the sleeve, a reset spring is mounted between the sleeve and the threaded rod, one end of the spring is connected with the sleeve, the other end of the spring is connected with the threaded rod, a wedge-shaped hole is mounted on the threaded rod, the wedge-shaped rod which is in a sliding connection with the wedge-shaped hole is arranged in the wedge-shaped hole, and the wedge-shaped rod is hydraulically driven. The wedge-shaped rod is hydraulically driven to be leftwards pushed, the threaded rod, the sleeve and the transverse board move downwards under the action of a wedge-shaped surface, the clamping jaws can clamp the workpiece under the action of the strip-shaped holes which are upwards inclined from inside to outside, and the workpiece can be well clamped and prevented from shifting.
Description
Technical field
The invention belongs to the technical field of anchor clamps, relate in particular to a kind of tapered bar mechanism of fluid pressure type automatic aligning fixture.
Background technology
Swing anchor clamps and be widely used in the manufacturing operation, 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.
Summary of the invention
The technical problem to be solved in the present invention 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 invention 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, the invention has the advantages that: 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 band motion plate pulls down, for being inclined upwardly from inside to outside, jaw can inwardly swing under the effect of bar hole such as the bar hole on the transverse slat, thus clamping work pieces, holding workpiece prevents its displacement preferably; In the time of need to 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 swing under the effect of bar hole, thereby unclamps workpiece such as the bar hole on the transverse slat.
Description of drawings
Below in conjunction with drawings and Examples technical solution of the present invention is further specified:
Fig. 1 is the structural representation of the tapered bar mechanism for implementing example of fluid pressure type automatic aligning fixture of the present invention.
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, the band motion plate 4 pull down, such as the bar hole on the transverse slat 4 for being inclined upwardly from inside to outside, jaw 5 can inwardly swing under the effect of bar hole, thereby clamping work pieces, holding workpiece prevents its displacement preferably; In the time of need to 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 swing under the effect of bar hole, thereby unclamps workpiece such 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 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.
