Abstract
The utility model discloses an expansive core shaft device that can guarantee a plurality holes with the same axis, which comprises a hollow optical axis (8), one end of which is provided with an external thread, a core shaft (5) which is provided with a guide wheel (11), an elongated slot and a plurality of taper sleeves (6). The core shaft (5) is punctured and sheathed in the hollow optical axis (8), the circumference of the hollow optical axis (8) which is corresponding to the taper sleeves (6) is provided with three long holes, a sliding block (7) that is matched with the taper sleeves (6) is riveted in the long hole by an elastic cylindrical pin (10), the hollow axis (8) is provided with a banking pin (9) which is blocked in the elongated slot of the core shaft (5), the end of the core shaft (5) is tightly fixed with a manual nut (2), the manual nut (2) can be screwed in the external thread of the hollow axis (8) which is fixed with a handle wheel (3). The tightening through expanding structure of the expansive core shaft device can be correspondingly enlarged or reduced according to the quantity of plates, and the length can be correspondingly prolonged or shortened according to spacing between the plates. The expansive core shaft device has the advantages of good coaxiality, convenient assembly and disassembly and light weight.
Description
Technical field
The utility model relates to the coaxial mandrel device of a kind of plate parts bond pads porous.
Background technology
The coaxial device of existing assurance plate parts bond pads porous is general to adopt a logical optical axis, the shortcoming of installing in this to be that loading and unloading difficulty, particularly plate parts group distance between plates are hour more outstanding, and hole each hole axiality more for a long time can not guarantee well.
Summary of the invention
The purpose of this utility model is that design a kind ofly guarantees that alignment is good, is convenient to load and unload, risen mandrel device easy to use.
The technical solution of the utility model is achieved in that the mandrel device that can rise comprises that there is externally threaded hollow optical axis an end, one has directive wheel, the mandrel of elongated slot and some tapered sleeves, mandrel is set in the hollow shaft, the circumference corresponding with the mandrel tapered sleeve is provided with three slotted holes on the hollow shaft, by the elastic cylindrical pin riveted joint slide block that cooperates with tapered sleeve is arranged in the slotted hole, there is banking pin to be stuck in the elongated slot of mandrel on the hollow shaft, prevent that mandrel from coming off, the end of mandrel is fastened with a manual nut by screw, manual nut can screw on the hollow shaft external screw thread, is fixed with a hand wheel on the hollow shaft.
During use, the mandrel device that can rise passes in the plate parts group hole of required welding, one holds hand wheel, another holds manual nut, the back-out of manual nut by screw thread can drive mandrel and move axially forward, the moving axially of mandrel makes tapered sleeve withstand the slide block footpath outwards to rise, outwards rise and plate endoporus tensioner by the footpath of slide block like this, guaranteed that a plurality of plate endoporus are coaxial.Can the screw-in by manual nut after welding is finished drive mandrel and tapered sleeve and move axially backward the slide block footpath is inwardly moved, the footpath of slide block is inwardly moved with the plate endoporus and is had big gap, can extract the mandrel device that can rise fast out.Can rise by the Tensioning structure of mandrel device can according to how many corresponding increases and decreases of plate, and the length of the mandrel device that can rise can be according to corresponding lengthening of pitch-row or shortening.
The risen mandrel device that the utility model provides can guarantee that the porous of plate parts bond pads is coaxial, and alignment is good, and compact conformation is easy to use, is convenient to loading and unloading.
Description of drawings
Fig. 1 is can the rise structural representation of an embodiment of mandrel device of the utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, screw 2, manual nut 3, hand wheel 4, key 5, mandrel 6, tapered sleeve 7, slide block 8, hollow shaft 9, banking pin 10, elastic cylindrical pin 11, directive wheel
As shown in the figure, the utility model mandrel device that can rise comprises that there is externally threaded hollow optical axis 8 end, one has directive wheel 11, the mandrel 5 of elongated slot and some tapered sleeves 6, mandrel 5 is set in the hollow shaft 8, circumference corresponding with mandrel tapered sleeve 6 on the hollow shaft 8 is provided with three slotted holes, by elastic cylindrical pin 10 riveted joints the slide block 7 that cooperates with tapered sleeve 6 is arranged in the slotted hole, there is banking pin 9 to be stuck in the elongated slot of mandrel 5 on the hollow shaft 8, prevent that mandrel 5 from coming off, the end of mandrel 5 is fastened with a manual nut 2 by screw 1, manual nut 2 can screw on hollow shaft 8 external screw threads, is fixed with a hand wheel 3 by key 4 on the hollow shaft 8.
The back-out of this mandrel device that rises by manual nut 2 can make mandrel 5 drive tapered sleeves 6 front and back to move axially with screwing in, and the front and back that mandrel 5 drives tapered sleeves 6 move axially and make slide block 7 to radially sliding outside to inside.Outwards move by the footpath of slide block 7 and to make itself and plate endoporus tensioner, thereby guarantee that a plurality of plate endoporus are coaxial; The footpath of slide block 7 is inwardly moved with the plate endoporus and is had big gap, can extract the mandrel device that can rise fast out.
The Tensioning structure of this mandrel device that rises can according to how many corresponding increases and decreases of plate, and the length of the mandrel device that can rise can be according to corresponding lengthening of plate spacing or shortening.Alignment is good, and compact conformation is easy to use, is convenient to loading and unloading, and is in light weight.
