The specific embodiment
As shown in Figure 1, the utility model comprises that bottom is provided with externally threaded turret head screw rod 6, is sleeved on the sleeve 7 of turret head screw rod 6 outsides and is sleeved on the impact handle 5 of sleeve 7 outsides, the geometric center position of described impact handle 5 is provided with for holding the through hole 5-1 of described sleeve 7, is provided with and the impact ring 8 that impacts handle 5 and match between the turret head of the top of described sleeve 7 and described turret head screw rod 6.
As shown in Figure 1, in the present embodiment, the utility model also comprises stud 4, the bottom of described turret head screw rod 6 is provided with the first screwed hole, one head thread of described stud 4 is connected in described the first screwed hole, the other end of described stud 4 be arranged on the second screwed hole of having treated on pin 3 and match.
As shown in Figure 1, in the present embodiment, between described impact ring 8 and the turret head of described turret head screw rod 6, be provided with pad 9.By selecting the pad 9 of different-thickness, can adjust stud 4 screw in treated pin 3 with the second screwed hole in length.
In conjunction with Fig. 2 and Fig. 3, in the present embodiment, described sleeve 7 and described through hole 5-1 matched in clearance, a side of described impact handle 5 is provided with the slot 5-2 being connected with described through hole 5-1, the equal diameters of the width of described slot 5-2 and described through hole 5-1; By by sleeve 7 alignment 5-2, can easily sleeve 7 be inserted in the through hole 5-1 impacting on handle 5.Described impact handle 5 the latter half outlines be shaped as lantern-shaped, the middle and upper part of described impact handle 5 is the handshake part 5-3 caving inward, the top of described impact handle 6 is that outwardly convex prevents the upwards convex edge 5-4 of slippage firmly time of hand.
Between each parts of pin extractor described in the utility model, be the mode of removably connecting, therefore, in production dismounting for connect the first workpiece 1 and second workpiece 2 with the second screwed hole when playing pin 3, this pin extractor can have following multiple occupation mode:
(1) as shown in Figure 4, when the bottom of turret head screw rod 6 with wait rise pin 3 with the second screwed hole while matching, directly turret head screw rod 6 bottom thread are connected to treated pin 3 with the second screwed hole in, then upwards pull out turret head screw rod 6, directly just can take out pin 3; Or by turret head screw rod 6 bottom thread be connected to wait rise pin 3 with the second screwed hole in after, again impact handle 5 is sleeved on to turret head screw rod 6 bottoms, and one hand or both hands are held and are impacted handle 5 and move upward, with impacting handle 5, collide the turret head of turret head screw rod 6 upper ends, once or repeated multiple times, the tighter pin 3 of having treated of cooperation can be taken out, very easy to use.
(2) as shown in Figure 5, when with the second screwed hole to have treated that pin 3 coordinates with workpiece not too tight, but the bottom of turret head screw rod 6 with wait rise pin 3 with the second screwed hole while mismatching, select one with treated pin 3 with the stud 4 that matches of the second screwed hole, one head thread of stud 4 is connected in the first screwed hole that is arranged on described turret head screw rod 6 bottoms, and by the other end of stud 4 screw in treated pin 3 with the second screwed hole in, when screw-in length is enough, upwards pull out turret head screw rod 6, directly just can take out pin 3; Or when screw-in length is enough, again impact handle 5 is sleeved on to turret head screw rod 6 bottoms, and one hand or both hands hold and impact handle 5 and move upward, with impacting handle 5, collide the turret head of turret head screw rod 6 upper ends, once or repeated multiple times, can coordinate tighter pin 3 taking-ups of having treated.By changing the stud 4 of different size, just can meet with the different various lifting pin work of having treated pin 3 of the second screwed hole specification, strong adaptability.
(3) as shown in Figure 6, when with the second screwed hole to have treated that pin 3 coordinates with workpiece too tight, even when a pin 3 gets rusty and links into an integrated entity with the first workpiece 1 and second workpiece 2, in unloading process, treated that pin 3 is difficult to separated taking-up with the first workpiece 1 with second workpiece 2, with impacting handle 5, collided turret head screw rod 6 upper end turret heads and be also difficult to take out and treated pin 3.Now, can first the turret head screw rod 6 that is connected with stud 4 be penetrated successively to pad 9, collide and impact ring 8 and sleeve 7, then stud 4 is screwed into treated pin 3 with the second screwed hole in certain length, owing to being subject to the constraint of sleeve 7, now turret head screw rod 6 starts stressed, and make to have treated that pin 3 is subject to pulling force upwards, and with spanner, fastening the turret head of described turret head screw rod 6, pin 3 can be slowly extracted in rotation reinforcing; In this process, also can hold and impact handle 5 and move upward with one hand or both hands, with impacting handle 5, upwards firmly collide and impact ring 8 and coordinate and carry out, also can cooperation is too tight, the pin 3 that takes up even getting rusty is extracted from the first workpiece 1 and second workpiece 2.
Above in extracting the process of having treated pin 3, prevent stud 4 screw in treated pin 3 with the second screwed hole in length long, top, destroy at the end take up pin 3 with the second screwed hole.By changing the pad 9 of different-thickness, can adjust stud 4 screw in treated pin 3 with the second screwed hole in length.
(4), when taking up pin 3 and do not carry the second screwed hole, need first on pin 3, to get out the second screwed hole taking up, then use this pin extractor according to above method.
The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every any simple modification of above embodiment being done according to the utility model technical spirit, change and equivalent structure change, and all still belong in the protection domain of technical solutions of the utility model.
