Description
Technical field
The present invention relates to a kind of frock clamp, relate in particular to a kind of broken-end tap and broken-end drill extractor.
Background technology
At present, general earlier by behind machined moulding and the baking vanish in the process of the component of machine that is processed with unthreaded hole or screwed hole, just can enter boring and clear silk link.Brill unthreaded hole instrument commonly used is for boring flower, and auger shell pit instrument is a screw tap.In the process of boring, because aspects such as artificial origin or tool materials tend to occur boring situation colored or that screw tap fractures.Expose surface of the work if bore the fracture of flower or screw tap, can rely on manually and broken end be clamped, little by little from the hole, screw out then with clamp.If but the fracture that bores flower or screw tap does not expose surface of the work, because the chuck of clamp is too big, can't stretch in the hole, therefore could take out after need breaking into pieces with the broken end that other instruments will be stayed workpiece inside, so not only waste time and energy, and cause the hole wall of surface of the work, unthreaded hole or the internal thread of screwed hole to damage easily, thus the precision in hole reduced, even cause workpiece to scrap; Simultaneously, the production efficiency of workpiece also can be influenced, and increased working strength of workers.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of broken-end tap and broken-end drill extractor, under the prerequisite of not damaging workpiece, can fast broken end be taken out.
Technical scheme of the present invention is as follows: a kind of broken-end tap and broken-end drill extractor, bracing frame with a through-pipe structure, wear adjusting rod in the centre bore of this bracing frame, the upper end of this adjusting rod exceeds the upper surface of bracing frame, and adjusting rod can axially move by relative bracing frame; And arranged on left and right sides below support frame as described above is provided with two clamping legs symmetrically, and the top of this clamping leg is towards the direction bending of adjusting rod, and the cantilever of bending place and support frame as described above bottom is hinged; End at described clamping leg bending part offers the bar shaped via hole, and bar shaped via hole on the two clamping legs intersects stack, and it is hinged to pass the lower end of described superimposed bar shaped via hole and described adjusting rod by same pin.
Adopt above technical scheme, because adjusting rod bracing frame relatively axially moves, when adjusting rod moves up and down, slippage in the bar shaped via hole of the pin of adjusting rod lower end on two clamping legs, and drive two clamping legs around the rotation of the hinge of bending place, make the lower end folding to the inside of two clamping legs or open laterally.The present invention utilizes screw tap and bores on the flower outer wall has these characteristics of flute, screw tap in the process of boring, occurs or bore the situation that flower fractures, and the fracture of screw tap or brill flower does not expose surface of the work, at this moment can regulate the distance size of two clamping leg lower ends by mobile adjusting rod, making the lower end of two clamping legs can stretch into broken-end tap or broken end bores in the flute on the flower outer wall, and then control the lower end folding to the inside of two clamping legs by adjusting rod, broken-end tap or broken end are bored the flower clamping, grasp bracing frame and it is rotated counterclockwise, can make broken-end tap or broken end bore flower and screw out workpiece thereupon, not only simply but also quick, also can not cause the workpiece damage.
The centre bore of above-mentioned bracing frame is the shoulder hole that last hypomere is big, interlude is little, and both convenient processing can be convenient to the adjusting rod assembling again; Hole wall at interlude is provided with internal thread, and described adjusting rod is threaded with support frame as described above, and adjusting rod and bracing frame adopt threaded engagement, and both connect reliably, and can or open and carry out more convenient and accurately adjusting the folding of clamping leg.
The hypomere of above-mentioned bracing frame centre bore is up-small and down-big taper type, interferes with bracing frame in folding or open process to prevent the clamping leg, makes the more compact structure of whole device.
Installing for the ease of the clamping leg, and guarantee the flexibility that the clamping leg rotates, fixedlys connected with the bottom surface of bracing frame in the upper end of above-mentioned cantilever, and the lower end of cantilever is hinged with the bending place of corresponding clamping leg by pin, and is spacing by split pin.
Above-mentioned adjusting rod is made up of handle, last polished rod section, thread segment and following polished rod section from top to bottom successively, and the diameter of each several part successively decreases from top to bottom successively.Handle is positioned at the top of bracing frame, utilizes instrumental purposes such as craft or spanner can drive whole adjusting rod rotation on handle, with convenient control to the clamping leg; The epimere of last polished rod section and bracing frame centre bore adapts, and can prevent effectively that adjusting rod from shaking and fractureing.
The bottom of above-mentioned clamping leg is a cylinder, offers groove on this cylindrical periphery.Cylindrical structure is adopted in the bottom of clamping leg, both has been convenient to stretch into broken-end tap or broken end and has bored in the flute on the flower outer wall, can increase the contact area with the flute wall again, makes in the process of taking out broken end clamping more reliable; On cylindrical periphery, offer groove, can effectively increase the clamping leg and the upward frictional force of flute wall that breaks end, break away from further to prevent clamping leg and broken end.
Forward and backward both sides at above-mentioned clamping leg are provided with reinforced support, and the upper end of this reinforced support is by being bolted on the bracing frame, and the inner surface of reinforced support is the plane, and outer surface is the conical surface.Reinforced support mainly plays a part to avoid the clamping leg to occur bending and deformation because of the arm of force is long.
Beneficial effect: the present invention can be fast takes out broken end under the prerequisite of not damaging workpiece, has ensured that the production efficiency of the machining accuracy of workpiece hole and workpiece is unaffected, has characteristics such as reasonable in design, simple to operate, time saving and energy saving, that labour intensity is little.
