Abstract
The invention discloses an internal clamping fixture comprising a base, clamping jaws which are used for compressing the upper surface of a work piece and a vertical mobile slider which serves as a force applying device; the clamping jaws are hinged with the base; the upper parts of the clamping jaws are driven ends which compress the upper surface of the work piece, and the lower parts of the clamping jaws are hinged with the base; a convex edge which is arranged on the vertical mobile slider is contacted with oblique surfaces on the clamping jaws; a return block is arranged below the oblique surfaces on the claming jaws; and a tripping block which is matched with the return block is arranged on the vertical mobile slider. According to the internal clamping fixture, the compression and the force unloading of the work piece can be realized only by pushing the vertical mobile slider upwards and downwards, the structure is simple, the cost is low, the whole operation process is quick and high-efficiency, and the use is convenient and quick.
Description
Technical field
The invention belongs to mechanical field, be specifically related to a kind of inner clamping device.
Background technology
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 to be processed, and for the ease of the processing of lathe to workpiece, need to have the clamping device that clamps from inside workpiece to fix workpiece, present clamping device complex structure, and operation is comparatively inconvenient.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of simple in structure, easy to operate inside clamping device.
In order to solve the problems of the technologies described above, the invention provides a kind of inner clamping device, comprise pedestal, be used for the jaw of workpiece pressing upper surface, as the vertical sliding movable slider of force application apparatus, described jaw and pedestal are hinged, its top is the upper surface of driven end workpiece pressing, and its underpart and pedestal are hinged; The inclined-plane of establishing on the convex edge of establishing on the vertical sliding movable slider and the jaw contacts, and the below on the above inclined-plane of jaw is provided with returns piece, and the vertical sliding movable slider is provided with and the piece of triping of returning piece and cooperating.
Because jaw and pedestal are hinged, the vertical sliding movable slider upwards promotes, the upper drive end of the pyramidal structure extruding jaw of its drive end, impel the jaw stretching, extension so that the upper surface of the driven end workpiece pressing of jaw with workpiece pressing; Downslide vertical sliding movable slider, because the drive end of vertical sliding movable slider is provided with projection, the lower drive end of projection collision jaw draws jaw in, cancellation is to the pressuring action of workpiece.Said structure is simple, with low cost, and whole operating process rapidly and efficiently, and is convenient and swift.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Structural representation when Fig. 1 is embodiment of the invention clamping;
Fig. 2 is the structural representation of the embodiment of the invention when unclamping.
The specific embodiment
As depicted in figs. 1 and 2, the invention provides a kind of inner clamping device, comprise pedestal 2, be used for the jaw 3 of workpiece pressing 1 upper surface, as the vertical sliding movable slider 4 of force application apparatus, described jaw 3 is hinged with pedestal 2, its top is the upper surface of driven end 31 workpiece pressings 1, and its underpart and pedestal are hinged; The inclined-plane of establishing on the convex edge of establishing on the vertical sliding movable slider 4 and the jaw contacts, and the below on jaw 3 the above inclined-plane is provided with returns piece 41, and vertical sliding movable slider 4 is provided with and the piece of triping of returning piece 41 and cooperating.
Because jaw 3 is hinged with pedestal 2, vertical sliding movable slider 4 upwards promotes, the upper drive end of the pyramidal structure extruding jaw 3 of its drive end, impel jaw 3 to stretch so that the upper surface of driven end 31 workpiece pressings 1 of jaw 3 with workpiece pressing 1; Downslide vertical sliding movable slider 4 is return piece 41 because the drive end of vertical sliding movable slider 4 is provided with, and the lower drive end 5 of returning piece 41 collision jaws 3 draws jaw 3 in, and cancellation is to the pressuring action of workpiece 1.Said structure is simple, with low cost, and whole operating process rapidly and efficiently, and is convenient and swift.
Above-described only is 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 can not affect effect of the invention process and practical applicability.
Claims (1)
1. inner clamping device, comprise pedestal, be used for the jaw of workpiece pressing upper surface, as the vertical sliding movable slider of force application apparatus, it is characterized in that: described jaw and pedestal are hinged, and its top is the upper surface of driven end workpiece pressing, and its underpart and pedestal are hinged; The inclined-plane of establishing on the convex edge of establishing on the vertical sliding movable slider and the jaw contacts, and the below on the above inclined-plane of jaw is provided with returns piece, and the vertical sliding movable slider is provided with and the piece of triping of returning piece and cooperating.
