Abstract
The utility model provides wedge iron which relates to a practical auxiliary tool on a drill press. The utility model comprises a wedge head, a wedge body and a wedge tail. A rear sleeve which cooperates with the wedge iron is arranged on the wedge iron, and the rear sleeve of which one end is provided with an opening is sheathed in from the wedge tail to the wedge head; the wedge iron can move in a reciprocating mode in an inner cavity of the rear sleeve along the axial direction of the rear sleeve, and a disengagement-stopping mechanism which prevents disengagement is arranged on the rear sleeve. The utility model is mainly used for dismounting a drilling head.
Description
Technical field
The utility model relates to a kind of drift, relates in particular to the drift of the dismounting drill bit that uses on a kind of drilling machine.
Background technology
Drift of the prior art only comprises wedge head, wedge body and wedge tail, needs one to hold drill bit in the use, waves hammer on the other hand, can not control dropping of drill bit, and directly the dropping of drill bit breaks cutting edge easily or lose, and uses very inconvenient.
Summary of the invention
The utility model has proposed a kind of combination drift that integrates drift and hammer function at deficiency of the prior art, and one hand operated gets final product during use.
This programme is realized by following technical measures: it comprises wedge head, wedge body and wedge tail, be characterized in, drift is provided with the back cover that cooperates with it, the back cover of this end opening is gone into by wedge Caudad wedge headgear, drift can be at back cover inner chamber along the back sleeve to moving back and forth, the back cover is provided with the anti-avulsion mechanism that prevents that drift from coming off, and can realize the bump of drift to drill bit on the other hand.
The beneficial effect of this programme can be learnt according to the narration to such scheme, in afterwards cover and wedge head relatively move, back cover inner chamber and the percussion of wedge tail can be pulled down drill bit, operating process only needs a hand, the another hand can be controlled dropping of drill bit, the utility model compared with prior art, the technical purpose that has realized.
The concrete characteristics of this programme also have, and described anti-avulsion mechanism is for being provided with protecgulum at described back cover openend, and protecgulum is provided with the through hole that is a bit larger tham wedge head diameter, the diameter of described wedge body match greater than the diameter of wedge head and protecgulum through hole and with back cover inner chamber and.Add protecgulum, protecgulum and wedge cooperating on one's body can effectively be controlled the wedge head, makes it unlikely by dropping out in the cover of back.The cover inner chamber is provided with the spring that is connected with the wedge tail in the back.Add spring and can make wedge tail and the terminal certain distance that keeps of back cover inner chamber, can effectively improve the percussion effect, spring produces deformation behind bump can make drift reset, thereby has improved service efficiency.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the prior art schematic diagram;
Fig. 2 is the utility model front view;
Among the figure, 1, the wedge head, 2, the wedge body, 3, the wedge tail, 4, protecgulum, 5, spring, 6, the back cover.
The specific embodiment
Shown in Fig. 1～2, the utility model comprises wedge head 1, wedge body 2, wedge tail 3, protecgulum 4, spring 5, back cover 6.Drift is provided with it the back cover 6 that cooperates, and the back cover 6 of this end opening is inserted in to wedge head 1 by wedge tail 3, can make drift at back cover 6 inner chambers along the back sleeve to moving back and forth, back cover 6 is provided with the anti-avulsion mechanism that prevents that drift from coming off.
The concrete characteristics of this programme also have, and described anti-avulsion mechanism is for being provided with protecgulum 4 at described back cover 6 openends, and protecgulum 4 is provided with the through hole that is a bit larger tham wedge head 1 diameter, the diameter of described wedge body 2 match greater than the diameter of wedge head 1 and protecgulum 4 through holes and with back cover inner chamber and.Cover 6 inner chambers are provided with the spring 5 that is connected with wedge tail 3 in the back.In back cover 6 and drift relatively moved, back cover 6 inner chambers can be pulled down drill bit with 3 percussions of wedge tail, and operating process only need a hand, the another hand can be controlled dropping of drill bit, the utility model compared with prior art, the technical purpose that has realized.Cover 6 inner chambers are provided with the spring 5 that is connected with wedge tail 3 in the back.Add spring 5 and can make wedge tail 3 and the terminal certain distance that keeps of back cover 6 inner chambers, can effectively improve the percussion effect.Spring produces deformation behind bump can make drift reset, thereby has improved service efficiency.
Claims (3)
1 one kinds of drifts comprise wedge head, wedge body and wedge tail, it is characterized in that, drift is provided with the back cover that cooperates with it, the back cover of this end opening is gone into by wedge Caudad wedge headgear, drift can be at back cover inner chamber along the back sleeve to moving back and forth, the back cover is provided with the anti-avulsion mechanism that prevents that drift from coming off.
2, drift according to claim 1, it is characterized in that, described anti-avulsion mechanism is for being provided with protecgulum at described back cover openend, and protecgulum is provided with the through hole that is a bit larger tham wedge head diameter, the diameter of described wedge body match greater than the diameter of wedge head and protecgulum through hole and with back cover inner chamber and.
3, drift according to claim 1 and 2 is characterized in that, the cover inner chamber is provided with the spring that is connected with the wedge tail in the back.
