Abstract
The utility model discloses a dual ejection type centering clamping device and relates to centering clamping devices. The dual ejection type centering clamping device comprises a base, a pull rod, two clamping jaws, two connecting blocks, two ejector rods and two ejector blocks. The base is provided with a groove in the axial direction, and the pull rod is mounted in the groove. The two connecting blocks are respectively welded on two sides of the base and respectively hinged with the two clamping jaws. Each of two axial sides of the pull rod is provided with one triangular groove and one circular arc groove, wherein the two triangular grooves are opposite to each other, and the two circular arc grooves are opposite to each other. The two ejector rods are respectively located on two sides of the pull rod. One end of one of the two ejector rods abuts against one clamping jaw, and one end of the other ejector rod abuts against the other clamping jaw. The other end of each of the two ejector rods is arranged in one triangular groove formed in the pull rod. The two ejector blocks are respectively located on the two sides of the pull rod. One end of one of the two ejector blocks is attached to one clamping jaw, and one end of the other ejector block is attached to the other clamping jaw. The other end of each of the two ejector blocks is arranged in one circular arc groove formed in the pull rod. By means of the dual ejection type centering clamping device, the defect that a workpiece is difficult to center and clamp, or the workpiece cannot be clamped firmly is overcome, and machining efficiency is improved.
Description
Technical field
The utility model relates to the centering and clamping apparatus technical field, particularly a kind of dual-top type centering and clamping apparatus.
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 firm dual-top type centering and clamping apparatus.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of dual-top type centering and clamping apparatus, comprise pedestal, pull bar, two jaws, two contiguous blocks, two push rods, two jacking blocks, described pedestal axially has groove, pull bar is installed in the groove, two contiguous blocks are welded on the both sides of pedestal respectively, two contiguous blocks are hinged with two jaws respectively, the axial both sides of described pull bar have relative two triangle grooves and two relative arc grooves, described two push rods lay respectively at the both sides of pull bar, one end of two push rods offsets with two jaws respectively, the triangle groove that the other end places pull bar to offer, described two jacking blocks lay respectively at the both sides of pull bar, and an end of two jacking blocks is fitted with two jaws respectively, the arc groove that the other end places pull bar to offer.
Have oval groove on described two jacking blocks, pedestal is provided with two alignment pins, and described two alignment pins pass described oval groove, and one section of described alignment pin and described oval groove is connected with back-moving spring.
Beneficial effect: the utility model simple structure, by the interlock mode that adopts pull bar, two push rods, two jacking blocks and two jaws workpiece is clamped, be easy to clamp by this structure, two jaws lay respectively at the both sides of pull bar, to firm workpiece clamping, can not produce looseningly, simultaneously be provided with back-moving spring in the jacking block, when not needing to clamp, clamping device can reset automatically.
Description of drawings
Fig. 1 is the schematic diagram of the utility model dual-top type centering and clamping apparatus structure embodiment.
The specific embodiment
Shown in Fig. 1, the utility model dual-top type centering and clamping apparatus, comprise pedestal 1, pull bar 2, two jaws 6, two contiguous blocks 5, two push rods 3, two jacking blocks 7, described pedestal 1 axially has groove, pull bar 2 is installed in the described groove, two connect 5 both sides that are welded on pedestal 1 respectively, two contiguous blocks 5 are hinged with two jaws 6 respectively, described pull bar 2 axial both sides have relative two triangle grooves 4 and two relative arc grooves 8, described two push rods 3 lay respectively at the both sides of pull bar 2, one end of two push rods 3 offsets with two jaws 6 respectively, the triangle groove 4 that the other end places pull bar 2 to offer, described two jacking blocks 7 lay respectively at the both sides of pull bar 2, one end of two jacking blocks 7 is fitted with two jaws 6 respectively, the arc groove 8 that the other end places pull bar to offer, offer oval groove respectively on two jacking blocks 7 simultaneously, pedestal 1 is provided with two alignment pins, described two alignment pins pass described oval groove, one section of described alignment pin and described oval groove is connected with back-moving spring, when two jacking blocks 7 can rotate respectively to the movement outside of pedestal 1 both sides, thereby two jaws that will be hinged on pedestal 1 twenty percent strut, and workpiece is located; After pull bar 2 was become flexible downwards, two push rods 3 were slowly to both sides, and two jacking blocks 7 slowly bounce back, and jaw 6 also and then bounces back.The utility model drives 6 motions of two jaws by the interlock of pull bar 2, two push rods 7, and workpiece is clamped, and this kind of drive very easily clamps workpiece, and it is fine to clamp effect.
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.
