Abstract
The utility model relates to the field of mechanical machining tool, in particular to a device for taking out a cracked screw tap. The device comprises a rod body and a claw strip, wherein the rod body and the claw strip are independent respectively and can be combined and connected with each other when in use. The rod body is provided with a rod wall with an external thread and a cylindrical rod core with tooth troughs arranged on the circumferential surface; the tail part of the claw strip is provided with a rack which is engaged with the tooth trough of the rod core; the rod wall is provided with a shrinking trough; and the outside of the rod wall is sheathed with a nut. The rod wall is arranged around the rod body; the rod core is arranged at the circle center of the rod body, with a ring of clearance away from the rod body; and the clearance is internally provided with a ring of elastic metal strip. The claw strip is assembled on the rod body which is inserted in a chip containing trough of the cracked screw tap, and the cracked screw tap can be easily and conveniently taken out of the thread hole by reverse rotation.
Description
Technical field
The utility model relates to the machine tools field, and especially a kind of broken filaments is stormed and captured out device.
Background technology
In machine-building and maintenance process, when using screw tap to carry out screw tapping, hard waste, because improper use causes screw tap to break in the screwed hole, be difficult to take out, at present, handling the instrument that this screw tap broken end adopts is electric drill, carries out tapping again after the screw tap in the hole of breaking is bored, if but drill bit misaligned aperture and hole drill is inclined to one side, then scrapped whole part, not only operating efficiency is low, and poor reliability.
The utility model content
To storm and capture out instrument efficient low in order to overcome existing broken filaments, the deficiency of poor stability, and the utility model provides a kind of broken filaments to storm and capture out device.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of broken filaments is stormed and captured out device, comprises the body of rod and pawl bar, and the body of rod and pawl bar are independent separately, are connected during use.
The body of rod is provided with the cylindrical bar core that has teeth groove with externally threaded bar wall and periphery.
Pawl bar afterbody is provided with the tooth bar that is meshed with the teeth groove of bar core.
Have retraction slot on the bar wall, the outside is with a nut.
The bar wall is positioned at the circumference of the body of rod, and the bar core is positioned at the center of circle of the body of rod, leaves a circle space between the two.
Be provided with a circle elastic metal strip in the space.
The beneficial effects of the utility model are, be assembled in the pawl bar on the body of rod after, insert the chip pocket of fracture screw tap, reverse rotation just can be taken out the fracture screw tap easily from screwed hole.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a body of rod schematic diagram of the present utility model;
Fig. 2 is a pawl bar schematic diagram of the present utility model;
Fig. 3 is a body of rod right view of the present utility model.
1. bodies of rod among the figure, 2. pawl bar, 11. bar walls, 12. bar cores, 3. nut, 4. metal tape.
The specific embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As Fig. 1 is schematic diagram of the present utility model, and Fig. 2 is a pawl bar schematic diagram of the present utility model, and a kind of broken filaments is stormed and captured out device, comprises the body of rod 1 and pawl bar 2, and the body of rod 1 and pawl bar 2 are independent separately, are connected during use.
As Fig. 3 is body of rod right view of the present utility model, and the body of rod 1 is provided with the cylindrical bar core 12 that has teeth groove with externally threaded bar wall 11 and periphery.Have retraction slot on the bar wall 11, the outside is with a nut 3.Bar wall 11 is positioned at the circumference of the body of rod 1, and bar core 12 is positioned at the center of circle of the body of rod 1, leaves a circle space between the two.Be provided with a circle elastic metal strip 4 in the space.
As Fig. 2 is pawl bar schematic diagram of the present utility model, and pawl bar 2 afterbodys are provided with the tooth bar that is meshed with the teeth groove of bar core 12.
During use, select the quantity of pawl bar 2 earlier according to the quantity of fracture screw tap chip pocket, if the screw tap of four grooves is then taken four pawl bars 2, if the screw tap of three-flute is then taken three pawl bars 2; Then pawl bar 2 is inserted the space, be evenly distributed on the circumference of bar core 12; Rotate nut 3 again, force bar wall 11 to clamp, thereby metal tape 4 is tightened up, and then wrap pawl bar 2, and metal tape 4 can make pawl bar 2 stressed even, and the tooth bar on the pawl bar 2 embeds in the teeth groove of bar core 12, can avoid displacement, improve stable degree, behind the fastening nut 3, what pawl bar 2 was just firm links into an integrated entity with the body of rod 1; At last pawl bar 2 is inserted the chip pocket of fracture screw tap, reverse rotation just can be taken out the fracture screw tap easily from screwed hole.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
