Technical field
The utility model relates to alignment pin extracting tool technical field, is specifically related to a kind of pin pulling out device, is used for extracting the taper pin or the pin that are threaded the hole.
Background technology
Taper pin, the pin of at present common all size are threaded the hole mostly; Yet when extracting these taper pins that are threaded the hole, pin; The following two kinds of methods of general employing: a kind of method is to adopt a screw rod to put the impact tup; Rely on the inertial impaction screw rod of impact head, gradually bearing pin is extracted from pin-and-hole; Another kind method is to adopt the method for push rod hammering that bearing pin is up to.More than two kinds of methods use and all have its limitation, first method to pull pin to need enough spaces of pulling pin, and efficient is lower; Second method then is to rely on to hit fully, and method is very original, and efficient very low and easy damage pin and pin-and-hole are having under the situation of particular requirement and can not use.
Summary of the invention
The utility model technical problem to be solved be a kind of structure of design simple relatively, practical, be easy to make and portable pin pulling out device, can solve pull pin limited space and the problem of raising the efficiency two aspects well.
For solving the problems of the technologies described above, the utility model has been taked following two kinds of technical schemes.
Scheme one is: a kind of pin pulling out device; Be used for extracting the taper pin or the pin that are threaded the hole, comprise screw rod, connecting pin, fittings body, sleeve and nut, wherein said screw rod is connected by said connecting pin with fittings body; The head of said fittings body has the thin sphenocephaly that the screwed hole with said taper pin or pin matches; The external screw thread of said screw rod forms with nut and is threaded, and said screw rod passes from said sleeve centre bore, and said nut is adjacent in said upper cartridge.Said sleeve is used to support stressed, bears the axial force of the relative rotation generation of said screw rod and nut, and will be delivered to the surface of the workpiece of pulling pin, and reaction force is extracted taper pin or pin.
The interior outage degree of said sleeve is greater than the length of said taper pin or pin.
Scheme two is: a kind of pin pulling out device; Be used for extracting the taper pin or the pin that are threaded the hole; Comprise screw rod, connecting pin, fittings body, sleeve and handle, wherein said screw rod is connected by said connecting pin with fittings body, and the head of said fittings body has the thin sphenocephaly that the screwed hole with said taper pin or pin matches; Said sleeve upper end has internal thread; Said screw rod passes from said sleeve centre bore, and the internal thread on the external screw thread of said screw rod and the said sleeve forms and is threaded, and said handle is installed in the top of said screw rod.Said sleeve not only can produce axial tension but also supports stressed; Rotate said sleeve, make said screw rod keep motionless with said handle simultaneously as far as possible, make said sleeve and screw rod relatively rotate the generation axial tension; And being delivered to the surface of the workpiece of pulling pin, reaction force is extracted taper pin or pin.
The interior outage degree of said sleeve is greater than the length of said taper pin or pin.
The outer surface annular knurl of said sleeve is conveniently exerted oneself when turnbarrel.
The invention has the beneficial effects as follows the problem that has solved the limited space of pulling pin well, and improved the efficient of pulling pin, be applicable to that the workpiece quantity of pulling pin is big, the reusable product of bearing pin.Be easy to carry, can adapt to the bearing pin of all size, can be used as the general instrument of pulling pin.
Description of drawings
Fig. 1 is the user mode section of structure of first embodiment of the utility model;
Fig. 2 is the user mode section of structure of second embodiment of the utility model.
The specific embodiment
Further specify below in conjunction with accompanying drawing and the specific embodiment technical scheme the utility model.
As shown in Figure 1, the utility model embodiment provides a kind of pin pulling out device, and this device comprises screw rod 1, connecting pin 4, fittings body 5, sleeve 3 and nut 2; Wherein screw rod 1 is connected by connecting pin 4 with fittings body 5; The head of fittings body 5 has the thin sphenocephaly that the screwed hole with pin 8 matches, and the external screw thread of screw rod 1 forms with nut 2 and is threaded, and screw rod 1 passes from sleeve 3 centre bores; Nut 2 is adjacent on sleeve 3 tops, and the interior outage degree of sleeve 3 is greater than the length of pin 8.
When needs are extracted the pin 8 that is installed in 7 li of the workpiece of pulling pin, the thin sphenocephaly of the head of fittings body 5 to be inserted in the screwed hole of pin 8, sleeve 3 lower ends are close on workpiece 7 surfaces of pulling pin; Rotating nut 2; Screw rod 1 and nut 2 produce rotation relatively, and sleeve 3 is used to support stressed, bear the axial force of the relative rotation generation of screw rod 1 and nut 2; And with the surface of axial force transmission to the workpiece 7 of pulling pin, consequent reaction force is extracted pin 8.
The foregoing description 1 is a turnbarrel not, can protect surface of the work injury-free; Do not have the situation of specific (special) requirements for surface of the work, can take technical scheme yet like following embodiment 2.
Embodiment 2
