Abstract
The invention discloses a wedge mechanism of a hydraulic type automatic aligning chuck. The wedge mechanism comprises a clamp body, a working platform, left and right clamping jaws, levers, a pull rod, a sleeve and a wedge-shaped rod, the left and right clamping jaws are used for clamping a workpiece, the pull rod vertically slides in the clamp body, the sleeve is arranged on the pull rod, the wedge-shaped rod serves as a force application device, the clamping jaws are movably connected with the working platform, the working platform is in a sliding connection with the clamp body, grooves are symmetrically arranged below the working platform, driven ends of the levers are placed in the grooves, driving ends of the levers are connected with the sleeve, a reset spring is mounted between the sleeve and the pull rod, one end of the spring is connected with the sleeve, the other end of the spring is connected with the pull rod, a wedge-shaped hole is arranged on the pull rod, the wedge-shaped rod which is in the 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 pull rod, the sleeve and the driving ends of the levers downwards move under the action of a wedge-shaped surface, the driving ends of the levers inwards swing, and thereby the workpiece can be well clamped.
Description
Technical field
The invention belongs to the technical field of anchor clamps, relate in particular to a kind of wedge mechanism of fluid pressure type automatic aligning chuck.
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 wedge mechanism of fluid pressure type automatic aligning chuck, comprise chuck body, workbench, a left side that is used for clamping work pieces, right jaw, lever, the pull bar that in chuck body, slides up and down, be located at the sleeve pipe on the pull bar, tapered shaft as force application apparatus, jaw is movably connected on the workbench, workbench and chuck body are slidingly connected, the below symmetry of workbench has groove, the driven end of lever places in the groove, the drive end of lever is connected on the sleeve pipe, be provided with back-moving spring between sleeve pipe and the pull bar, one end of spring is connected with sleeve pipe, the other end is connected with pull bar, pull bar 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, because of the effect of lozenges, pull bar and sleeve pipe move downward, and the drive end that drives lever pulls down, the drive end of lever inwardly swings, thereby clamping work pieces, holding workpiece prevents its displacement preferably; Workpiece in the time of need to unclamping does not apply external force to tapered shaft, and the drive end of lever can float under the effect of back-moving spring voluntarily, and the driven end of lever outwards swings, thereby unclamps workpiece.
Further, be provided with backstay between described workbench and the jaw, can regulate by backstay the position of jaw.
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 a kind of embodiment of wedge mechanism of fluid pressure type automatic aligning chuck of the present invention.
The specific embodiment
As shown in Figure 1, the wedge mechanism of a kind of fluid pressure type automatic aligning of the present invention chuck, comprise chuck body, workbench 6, a left side that is used for clamping work pieces, right jaw, lever 5, the pull bar 3 that in chuck body, slides up and down, be located at the sleeve pipe 4 on the pull bar 3, tapered shaft 1 as force application apparatus, jaw is movably connected on the workbench 6, be provided with backstay between described workbench 6 and the jaw, can regulate by backstay the position of jaw, workbench 6 and jaw are by bolt 7 location, workbench 6 is slidingly connected with chuck body, the below symmetry of workbench 6 has groove, the driven end of lever 5 places in the groove, the drive end of lever 5 is connected on the sleeve pipe 4, be provided with back-moving spring 8 between sleeve pipe 4 and the pull bar 3, one end of back-moving spring 8 is connected with sleeve pipe 4, and the other end is connected with pull bar 3, and pull bar 3 is provided with wedged hole 2, be provided with in the wedged hole 2 and itself and the tapered shaft 1 that is slidingly connected, described tapered shaft 1 is by hydraulic-driven.
When needing clamping work pieces, tapered shaft 1 promotes left under the driving of hydraulic pressure, because of the effect of lozenges, pull bar 3 and sleeve pipe 4 move downward, and the drive end that drives lever 5 pulls down, and the drive end of lever 5 inwardly swings, thereby clamping work pieces, holding workpiece prevents its displacement preferably; Workpiece in the time of need to unclamping does not apply external force to tapered shaft 1, and the drive end of lever 5 can float under the effect of back-moving spring 8 voluntarily, and the driven end of lever 5 outwards swings, thereby unclamps workpiece.
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.
Claims (2)
1. the wedge mechanism of a fluid pressure type automatic aligning chuck, comprise chuck body, workbench, a left side that is used for clamping work pieces, right jaw, lever, the pull bar that in chuck body, slides up and down, be located at the sleeve pipe on the pull bar, tapered shaft as force application apparatus, it is characterized in that: jaw is movably connected on the workbench, workbench and chuck body are slidingly connected, the below symmetry of workbench has groove, the driven end of lever places in the groove, the drive end of lever is connected on the sleeve pipe, be provided with back-moving spring between sleeve pipe and the pull bar, one end of spring is connected with sleeve pipe, the other end is connected with pull bar, pull bar is provided with wedged hole, be provided with in the wedged hole and itself and the tapered shaft that is slidingly connected, described tapered shaft is by hydraulic-driven.
