Abstract

The invention discloses a transmission centering clamping device with a rotation axes and relates to a centering clamping device. The transmission centering clamping device with the rotation axes comprises a machine frame, an upper die block, a middle die block, a lower die block, a rotation handle, two clamping claws and two ejecting blocks. The upper die block, the middle block and the lower die block are connected through bolts. Nuts of the bolts are embedded in the lower die block which is connected with the rotation handle in a welded mode. The two clamping claws are respectively hinged with the machine frame. Screws are respectively arranged at the lower ends of the two clamping claws. Nuts of the screws are respectively attached with two ends of the middle die block. A through hole is formed in the top of the upper die block. The two ejecting blocks are arranged in the through hole. A reset spring is arranged between the two ejecting blocks which are respectively attached with the two clamping claws. The transmission centering clamping device with the rotation axes overcomes the defects that centering claming for a work pieces is difficult to achieve or clamping is not firm, and improves machining efficiency.

Description

The rotary transmission centering and clamping apparatus in a kind of axle center
Technical field
The present invention relates to the centering and clamping apparatus technical field, particularly the rotary transmission centering and clamping apparatus in a kind of axle center.
Background technology
At present centering and clamping apparatus a large amount of use in machining, clamping device is that the workpiece of having good positioning is fixed on setting element in whole process reliably, and the occurrence positions mechanism that changes not.Do not allow to destroy the location of workpiece when clamping work pieces, and enough rigidity should be arranged, guarantee necessary clamping force, but should not damage the workpiece machined surface or make workpiece produce distortion, thereby guarantee machining accuracy.Because the outer surface of most of workpiece need to be processed, for the ease of the processing of lathe to workpiece, present clamping device complex structure, and operation is comparatively inconvenient, be difficult to the workpiece clamping of feeling relieved, or centering clamp firm not, the poor effect that its centering is clamped, greatly reduce working (machining) efficiency, larger impact is played in production.
Summary of the invention
The invention provides a kind of simple in structurely, workpiece is easy to clamp, clamp the firmly rotary transmission centering and clamping apparatus in axle center.
in order to solve the problems of the technologies described above, the invention provides following technical scheme: the rotary transmission centering and clamping apparatus in a kind of axle center, comprise frame, upper module, middle module, lower module, rotating handles, two jaws, two jacking blocks, described upper module, middle module, lower module is bolted, the nut of described bolt embeds in lower module, lower module and rotating handles welding, two jaws are hinged with frame respectively, the bottom of two jaws is respectively equipped with screw, the nut of screw is fitted with the two ends of middle module respectively, the top of upper module has a cross through hole, be provided with two jacking blocks in cross through hole, back-moving spring between two jacking blocks, two jacking blocks are fitted with two jaws respectively.
Beneficial effect: the present invention is simple in structure, rotate by the axle center swivel bolt, upper module moves, thereby two jacking blocks establishing in the drive upper module, finally be hinged on frame two jaws with Workpiece clamping, adopt this clamping mode that workpiece is very easily clamped, two jaws clamp and put in place, to firm workpiece clamping.
Description of drawings
Fig. 1 is the schematic diagram of axle center of the present invention rotary transmission centering and clamping apparatus structure embodiment.
The specific embodiment
as shown in Fig. 1, the rotary transmission centering and clamping apparatus in axle center of the present invention, comprise upper module 8, middle module 5, lower module 1, rotating handles 3, two jaws 6, two jacking blocks 7, frame 10, described upper module 8, middle module 5, lower module 1 connects by bolt 2, the nut of described bolt 2 embeds in lower module 1, lower module 1 and rotating handles 3 welding, two jaws 6 are hinged with frame 10 respectively, the bottom of two jaws 6 is respectively equipped with screw 4, the nut of screw 4 is fitted with the two ends of middle module 5 respectively, the top of upper module 8 has a cross through hole, be provided with two jacking blocks 7 in cross through hole, back-moving spring 9 between two jacking blocks, two jacking blocks 7 are fitted with two jaws 6 respectively.Workpiece is placed between two jaws 6, when beginning to clockwise rotate rotating handles 3 be, lower module also begins to rotate simultaneously, middle module 5 and upper module 8 are due to the effect of bolt 2, they also turn thereupon understands, and move down, upper module this moment 8 tops are provided with two jacking blocks 7 moving down due to upper module, two jacking blocks 7 draw in to the centre, the back-moving spring that between them, this has is compressed, because medium position and the frame of two jaws 6 are hinged, above-mentioned motion effect makes the opening on the top of two jaws draw in, and workpiece centering clamps the most at last; When needs take off workpiece, rotate counterclockwise rotating handles 3, compressed back-moving spring utilizes reaction force that two jacking blocks 7 are flicked to both sides when clamped condition, and two jacking blocks 7 and two jaws 6 are fitted simultaneously, at last two jaws 6 are strutted.
Above-described is only the preferred embodiment of the present invention; should be understood that; 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.
