Abstract
The invention discloses an internal clamping fixture comprising a base, a left clamping jaw and a right clamping jaw which are hinged with the base and a push rod with the end being in a conical shape; the push rod and the base are vertically and slidably connected; oblique surfaces which are matched with the conical structure of the push rod are arranged on the clamping jaws; and the driven ends of the clamping jaws are contacted with a work piece. According to the internal clamping fixture, the whole clamping fixture has a simple structure and is convenient to operate by adopting a gradation effect, and the clamping can be realized only by applying appropriate pushing force to the push rod.
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 base, the push rod tapered with the hinged left and right jaw of base and end, described push rod is vertical with base to be slidingly connected; Described jaw is provided with the inclined-plane that is complementary with the push rod pyramidal structure; The driven end contact workpiece of jaw.
Jaw in the such scheme directly contacts workpiece, jaw under the push rod active force of end alternation around outwards launching with the rotation of the hinged point of base, thereby top tight workpiece is inner, realizes the inside clamping to workpiece.The present invention has adopted the effect of alternation so that whole clamping device is simple in structure and easy to operate, only needs that push rod is applied suitable thrust and just can realize the work that clamps.
As the further restriction of technical solution of the present invention, can better reset in order to make jaw, be provided with spring between jaw and the base.
Further restriction as technical solution of the present invention, in order to make the not change of relative position between jaw and the workpiece, do not produce slip between jaw and the workpiece, described jaw is provided with dentalation, dentalation has reduced the contact area between jaw and the workpiece, under same active force, increase pressure, thereby increased stability.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment
As shown in Figure 1, the invention provides a kind of inner clamping device, comprise base 6, the push rod 4 tapered with the hinged jaw 3 of base 6 and end, described push rod 4 and base 6 vertical being slidingly connected; Described jaw 3 is provided with the inclined-plane that is complementary with push rod 4 pyramidal structures; The driven end contact workpiece 1 of jaw 3.Jaw 3 directly contacts workpiece 1, and the inclined-plane that the taper surface of push rod 4 promotes on the jaw 3 rotates jaw, thereby top tight workpiece 1 inside realizes the inside of workpiece 1 is clamped.This programme has adopted the effect of alternation so that whole clamping device is simple in structure and easy to operate, only needs that push rod 4 is applied suitable thrust and just can realize the work that clamps; For jaw 3 can better be resetted, be provided with spring 5 between jaw 3 and the base 6; In order to make the not change of relative position between jaw 3 and the workpiece 1, do not produce slip between jaw 3 and the workpiece 1, described jaw 3 is provided with dentalation 2, dentalation 2 has reduced the contact area between jaw 3 and the workpiece 1, under same active force, increase pressure, thereby increased stability.
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.
