Abstract
The utility model discloses a universal clamp capable of taking out a broken screw. The universal clamp is characterized by comprising a clamp body, a fixing plate, a drill sleeve, a pin shaft and a fastening bolt; a large hole and a small hole are arranged at one end of the clamp body; a long hole is arranged at the other end of the clamp body; the fastening bolt capable of moving along the long hole is arranged inside the long hole; a round hole is arranged at one end of the fixing plate; the long hole is arranged at the other end of the fixing plate; the fastening bolt capable of moving along the long hole is arranged in the long hole; the pin shaft sequentially passes through the small hole and the round hole to connect and fix the clamp body and the fixing plate, and the drill sleeve is arranged on the large hole. The universal clamp has the beneficial effects that the broken screw can be rapidly and conveniently taken out from a work-piece without damaging the original thread of the work-piece, thereby solving the problem of taking out the broken bolt in assembling and maintaining processes.
Description
Technical field
The utility model relates to mechanical engineering technical field, specially refers to a kind of universal fixturing that takes out the fracture screw.
Background technology
In the I& M of engineering goods, often run into fastening bolt and break in the workpiece, take out difficulty, this has brought great inconvenience for the replacing parts.The method of taking out break bolt in the real work mainly contains the welding screw rod, adopts the Broken bolt extractor, chit drill fluting, resin encapsulating, bores division etc. step by step according to the difference of the each side factors such as material, size and function thereof of its fracture location, construction space, bolt; But use at present and bore division the most step by step; Owing in boring the process of removing, be prone to sideslip, skid; It is low to lose drill bit, damage matrix screw thread and working (machining) efficiency, so the drill tools that draws of design special just seems very necessary to addressing this problem.
Because fracture location is often in interior, the surface does not have exposed portions serve, takes out very difficulty.Using at present is to bore division step by step the most widely, owing to boring except that being prone to sideslip in the process, skidding, lose drill bit, damage workpiece substrate screw thread (the screw thread damage seriously will cause workpiece to be scrapped), and operating efficiency is low.
The utility model content
The purpose of the utility model is to provide a kind of universal fixturing that takes out the fracture screw, through the employing special structural design, thus the purpose of realization the utility model.
The technical problem that the utility model solved can adopt following technical scheme to realize:
A kind of universal fixturing that takes out the fracture screw is characterized in that, comprises clamp body, fixed head, drill bushing, bearing pin and trip bolt; One end of said clamp body is provided with macropore and aperture, and the other end of clamp body is provided with slotted hole, and the trip bolt that can move along slotted hole is installed in the slotted hole; One end of said fixed head is provided with circular hole, and the other end of fixed head is provided with slotted hole, and the trip bolt that can move along slotted hole is installed in the slotted hole; Bearing pin passes aperture and circular hole successively and clamp body is connected fixing with fixed head, and drill bushing is installed on the said macropore.
In an embodiment of the utility model, an end of said clamp body and fixed head all is provided with ledge structure.
The beneficial effect of the utility model is: make the fracture screw can from workpiece, take out and not damage original screw thread of workpiece fast, easily, solved the difficult problem in assembling and the taking-up of maintenance cleaved screw.

The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with the specific embodiment, further set forth the utility model.
As shown in Figure 1, the described a kind of universal fixturing that takes out the fracture screw of the utility model mainly is made up of clamp body 100, fixed head 200, drill bushing, bearing pin and trip bolt.
As shown in Figures 2 and 3, clamp body one end has two holes and a step, and macropore 112 is installed drill bushings, and aperture 113 is installed bearing pins and is connected with fixed head, step and fixed head cooperation, guarantee the two cooperation installation after, develop with the working face of workpiece.In the middle of the other end first slotted hole 111 being arranged, is that first trip bolt, 110 pressing clips are specifically used.Because the part that uses is different, trip bolt can move in slotted hole, regulates the distance with the fracture screw.
Like Fig. 4 and shown in Figure 5; Fixed head one end has a circular hole 212 and a step, and circular hole is installed bearing pin and is connected cooperation with clamp body, and the step effect is identical with step on the clamp body; The other end also has second slotted hole 211, supplies second trip bolt 210 to be fixed plate and adjustable range usefulness.
Installing hole tight fit on drill bushing external diameter and the clamp body, internal diameter is slightly less than the path of screw, makes with high-carbon steel or steel alloy, just can install and use after the quenching.Changing different drill bushings according to the size of fracture screw can use.
Bearing pin can be connected clamp body with fixed head, and can rotate around it.
The bit diameter that uses gets final product than the little 0.02～0.03mm of drill bushing internal orifice dimension.
Earlier clamp body and fixed head are utilized original screw through trip bolt during use; Be pressed on the workpiece 300 and (do not press too tightly),, can be adjusted to suitable position because clamp body and fixed head all have slotted hole; Make drill bushing align the hole of break bolt; Tighten trip bolt then, on drilling machine or use electric hand drill, the screw that will rupture gets out.
The beneficial effect of the utility model is: make the fracture screw can from workpiece, take out and not damage original screw thread of workpiece fast, easily, solved the difficult problem in assembling and the taking-up of maintenance cleaved screw.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
