Abstract
The utility model discloses a wedge mechanism of a hydraulic automatic centering chuck, which comprises the following components: a clamp body, an operation platform, a left clamping pawl and a right clamping pawl which are used for clamping a workpiece, a lever, a pull rod which vertically slides in the clamp body, a sleeve which is arranged on the pull rod, and a wedge-shaped rod which is used as a force applying device. The clamping pawls are movably connected with the operation platform. The operation platform is slidably connected with the clamp body. Grooves are arranged below the operation platform. The driven rod of the lever is placed in the groove, and the driving end of the lever is connected with the sleeve. A reset spring is provided between the sleeve and the pull rod. One end of the spring is connected with the sleeve, and the other end is connected with the pull rod. The pull rod is provided with a wedge-shaped hole which is internally provided with the wedge-shaped rod that is slidably connected with the wedge-shaped hole. The wedge-shaped rod is driven by hydraulic pressure. The wedge-shaped rod according to the utility model pushes leftwards under hydraulic driving. Because of the function of the wedge-shaped surface, the pull rod, the sleeve and the driving end of the lever move downwards; and the driving end of the lever swings inwards, thereby clamping the workpiece. Therefore the workpiece can be better clamped.
Description
Technical field
The utility model belongs to the technical field of fixture, relates in particular to a kind of wedge mechanism of fluid pressure type automatic aligning chuck.
Background technology
Swing fixture and be widely used in manufacturing operation, the swing by bare terminal end carrys out the loading and unloading workpiece.In existing clamp assembly, workpiece is fixed in place by the coupling between himself physical form and 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 if 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 is to provide a kind of swing hold down gag, and holding workpiece, prevent its displacement preferably.
in order to solve the problems of the technologies described above, the utility model 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 slides up and down in chuck body, be located at the sleeve pipe on pull bar, tapered shaft as force application apparatus, jaw is movably connected on workbench, workbench and chuck body are slidably connected, the below symmetry of workbench has groove, the driven end of lever is placed in groove, the drive end of lever is connected on sleeve pipe, be provided with back-moving spring between sleeve pipe and 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 the tapered shaft that is slidably connected with it in wedged hole, described tapered shaft is by hydraulic-driven.
Compared with prior art, the utility model has the advantage of: while 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, prevent its displacement preferably; Workpiece in the time of need to unclamping, do not apply external force to tapered shaft, and the drive end of lever can float voluntarily under the effect of back-moving spring, and the driven end of lever outwards swings, thereby unclamps workpiece.
Further, be provided with backstay between described workbench and jaw, can regulate by backstay the position of jaw.
Description of drawings
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Fig. 1 is the structural representation of a kind of embodiment of wedge mechanism of the utility model fluid pressure type automatic aligning chuck.
The specific embodiment
as shown in Figure 1, the wedge mechanism of a kind of fluid pressure type automatic aligning of the utility model 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 slides up and down in chuck body, be located at the sleeve pipe 4 on pull bar 3, tapered shaft 1 as force application apparatus, jaw is movably connected on workbench 6, be provided with backstay between described workbench 6 and jaw, can regulate by backstay the position of jaw, workbench 6 and jaw are by bolt 7 location, workbench 6 is slidably connected with chuck body, the below symmetry of workbench 6 has groove, the driven end of lever 5 is placed in groove, the drive end of lever 5 is connected on sleeve pipe 4, be provided with back-moving spring 8 between sleeve pipe 4 and pull bar 3, one end of back-moving spring 8 is connected with sleeve pipe 4, the other end is connected with pull bar 3, pull bar 3 is provided with wedged hole 2, be provided with the tapered shaft 1 that is slidably connected with it in wedged hole 2, described tapered shaft 1 is by hydraulic-driven.
While 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, prevent its displacement preferably; Workpiece in the time of need to unclamping, do not apply external force to tapered shaft 1, and the drive end of lever 5 can float voluntarily under the effect of back-moving spring 8, 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 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 affect effect and practical applicability that the utility model is implemented.
Claims (2)
