Abstract
The utility model discloses a grooving frock used in a drill press, consisting of a knife sheath, a spring, a pin, a knife bar, a stopping ring and a lathe tool; wherein a knife bar hole is eccentrically arranged in the knife sheath; the knife bar is arranged in the knife bar hole; a spiral groove is arranged at the center of the lateral wall of the knife sheath; the pin is arranged in the spiral groove and is fixedly connected with the knife bar; the spring is arranged between the end part of the knife bar and the bottom of the knife bar hole; the lathe tool is fixedly arranged at the front end of the knife bar; the stopping ring is arranged on the knife bar through a tight bolt case. The grooving frock used in a drill press of the utility model adopts the structure that the eccentric knife bar hole and the spiral groove are arranged in the knife sheath to change the movement track of the lathe tool which is arranged at the end part of the knife bar through the eccentric knife bar hole and the spiral groove, thus realizing the function of groove cutting in a spare part hole, enlarging the processing scope of a drill; simplifying the structure and facilitating the application.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to metal-cutting machine tool, particularly a kind of grooving frock that is used for drilling machine.
Background technology:
Often need with drilling machine grooving in the hole in the production.In the prior art, need special-purpose cutter, could finish the processing of groove with drilling machine, so production efficiency is low.
Summary of the invention:
The purpose of this utility model provides a kind of grooving frock that is used for drilling machine, and the described this grooving frock that is used for drilling machine will solve the directly technical problem of working groove in the hole of part of prior art drilling machine.
This grooving frock that is used for drilling machine of the present utility model, wherein, described grooving frock is by broach shell, spring, pin, knife bar, locating snap ring, constitute with lathe tool, be provided with the knife bar hole in the described broach shell prejudicially, described knife bar is arranged in the knife bar hole, described broach shell sidewall middle part is provided with helicla flute, described pin is arranged in the described helicla flute, described pin and described knife bar are fixedly linked, described spring is arranged between described knife bar end and the bottom, described knife bar hole, described lathe tool is fixedly set in described knife bar front end, and described locating snap ring is arranged on the described knife bar by the holding screw socket, and be positioned at the below of broach shell.
Further, described helicla flute be dextrorotation to.
Operation principle of the present utility model is: broach shell is connected with drill press spindle, downward push type broach cover when drilling machine rotates, because locating snap ring restriction knife bar can not move downward, broach shell and knife bar produce along helicla flute by pin and move to axial and rotate, because broach shell is installed the hole of knife bar certain offset is arranged, so broach shell and knife bar have changed the radius of gyration of lathe tool simultaneously in relative rotation, realize feed, recessing.After finishing groove processing, broach shell moves upward, and under spring action, broach shell and knife bar return to original state.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is arranged at eccentric knife bar hole and helicla flute in the broach shell, changes the movement locus of knife bar end lathe tool by eccentric knife bar hole and helicla flute, thereby is implemented in the function of grooving in the hole in piece part, has enlarged the range of work of boring, and is simple in structure, easy to use.
Description of drawings:
Fig. 1 is the structural representation that is used for the grooving frock of drilling machine of the present utility model.
The specific embodiment:
As shown in Figure 1, the grooving frock that is used for drilling machine of the present utility model, wherein, described grooving frock is by broach shell 1, spring 2, pin 3, knife bar 4, locating snap ring 5, constitute with lathe tool 6, be provided with the knife bar hole prejudicially in the described broach shell 1, described knife bar 4 is arranged in the knife bar hole, described broach shell 1 sidewall middle part is provided with helicla flute 7, described pin 3 is arranged in the described helicla flute 7, described pin 3 is fixedly linked with described knife bar 4, described spring 2 is arranged between described knife bar 4 ends and the bottom, described knife bar hole, described lathe tool 6 is fixedly set in described knife bar 4 front ends, and described locating snap ring 5 is arranged on the described knife bar 4 by holding screw 8 sockets, and be positioned at the below of broach shell 1.
Further, described helicla flute 7 be dextrorotation to.
Concrete, broach shell 1 is connected with the main shaft 9 of drilling machine during use, downward push type broach cover 1 when drilling machine rotates, because locating snap ring 5 restriction knife bars 4 can not move downward, broach shell 1 and knife bar 4 produce along helicla flute 7 by pin 3 and move to axial and rotate, because broach shell is installed the hole of knife bar certain offset are arranged, so broach shell 1 and knife bar 4 are simultaneously in relative rotation, change the radius of gyration of lathe tool 6, realized feed, recessing.After finishing in the part 10 groove processing, broach shell 1 moves upward, and under spring 2 effects, broach shell 1 and knife bar 4 return to original state.
Claims (2)
1. grooving frock that is used for drilling machine, by broach shell, spring, pin, knife bar, locating snap ring and lathe tool constitute, it is characterized in that: be provided with the knife bar hole in the described broach shell prejudicially, described knife bar is arranged in the knife bar hole, the inwall middle part of described broach shell is provided with helicla flute, described pin is arranged in the described helicla flute, pin is fixedly linked with knife bar, described spring is arranged between the bottom in the end of knife bar and knife bar hole, described lathe tool is fixedly set in the front end of knife bar, and described locating snap ring is arranged on the knife bar by the holding screw socket, and be positioned at the below of broach shell.
