Abstract
The utility model discloses an axis rotation type transmission centering clamping device, and relates to a centering clamping device. The axis rotation type transmission centering clamping device comprises a rack, an upper module, a middle module, a lower module, a rotating handle, two clamping jaws and two top blocks. The upper module, the middle module and the lower module are connected through a bolt, and a screw cap of the bolt is embedded into the lower module. The lower module and the rotating handle are welded. The two clamping jaws are respectively connected with the rack in a hinged mode. Bolts are arranged at the bottom ends of the two clamping jaws, and screw caps of the bolts are respectively attached to two ends of the middle module. A through hole is formed in the top of the upper module, and the two top blocks are arranged in the through hole. A reset spring is arranged between the two top blocks, and the two top blocks are respectively attached to the two clamping jaws. The axis rotation type transmission centering clamping device overcomes the defects that centering and clamping of a workpiece can not be conducted easily or clamping is not firm, and improves processing efficiency.
Description
Technical field
The utility model 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
Centering and clamping apparatus a large amount of use in machining at present, clamping device is that the workpiece of having good positioning is fixed on the setting element in whole process reliably, and the mechanism that changes of occurrence positions not.When clamping work pieces, do not allow to destroy the location of workpiece, 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 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 inadequately, the poor effect that its centering is clamped, greatly reduce working (machining) efficiency, bigger influence is played in production.
The utility model content
It is a kind of simple in structure that the utility model provides, and workpiece is easy to clamp, and clamps the rotary transmission centering and clamping apparatus in firm axle center.
In order to solve the problems of the technologies described above, the utility model 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 connects by bolt, the nut of described bolt embeds in the 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 the cross through hole, back-moving spring between two jacking blocks, two jacking blocks are fitted with two jaws respectively.
Beneficial effect: the utility model is simple in structure, rotate by the axle center swivel bolt, upper module moves, thereby two jacking blocks establishing in the drive upper module, be hinged on finally that two jaws clamp workpiece on the frame, 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 the utility model axle center rotary transmission centering and clamping apparatus structure embodiment.
The specific embodiment
Shown in Fig. 1, the rotary transmission centering and clamping apparatus in the utility model axle center, 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 the 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 the cross through hole, 9, two jacking blocks 7 of back-moving spring are fitted with two jaws 6 respectively between two jacking blocks.Workpiece is placed between two jaws 6, when beginning to clockwise rotate rotating handles 3, lower module also begins to rotate simultaneously, middle module 5 and upper module 8 are because the effect of bolt 2, they also change thereupon and understand, and move down, this moment, upper module 8 tops were provided with two jacking blocks 7 moving down owing to upper module, two jacking blocks 7 draw in to the centre, the back-moving spring that this has between them is compressed, because medium position and the frame of two jaws 6 are hinged, above-mentioned motion effect makes the opening on top of two jaws draw workpiece centering clamping the most at last in; 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 6 applyings of two jaws strut two jaws 6 at last simultaneously.
Above-described only is preferred embodiment of the present utility model; should be understood that; 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.
