Abstract
The utility model discloses a kind of pipe fitting boring cutter, comprise housing and knife rest; Described knife rest includes the drill bit being arranged in housing, annular cutter head, backstay, spring and holding screw; Described drill bit is arranged on the axle center of annular cutter head below, and the periphery of described drill bit includes a horizontal step through-hole, and described backstay, spring and holding screw are all arranged in step through-hole, and fix by holding screw; Described spring is arranged between backstay and holding screw, and one end of described backstay is arc end and leads to the outside of drill bit, the other end and spring contact.Operation is very easy for pipe fitting boring cutter of the present utility model.
Description
Technical field
The utility model belongs to cutter field, is specifically related to a kind of pipe fitting boring cutter.
Background technology
After traditional pipe fitting boring cutter perforate, the fragment of its smear metal can be fallen in the hole of pipe fitting, also it will be taken out, and very trouble, and the external diameter of fragment and the external diameter of perforate approach, and take very inconvenient.
Utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model is to propose a kind of pipe fitting boring cutter, to solve the take problem of trouble of fragment in conventional art.
(2) technical scheme
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of pipe fitting boring cutter, comprises housing and knife rest; Described knife rest includes the drill bit being arranged in housing, annular cutter head, backstay, spring and holding screw; Described drill bit is arranged on the axle center of annular cutter head below, and the periphery of described drill bit includes a horizontal step through-hole, and described backstay, spring and holding screw are all arranged in step through-hole, and fix by holding screw; Described spring is arranged between backstay and holding screw, and one end of described backstay is arc end and leads to the outside of drill bit, the other end and spring contact.
Described housing comprises handgrip, in described handgrip, is provided with chip-removal hole.
The material of described housing is aluminium alloy.
Described backstay is a steel ball.
The fixed support of an arc structure is arranged at the bottom of described housing.
(3) beneficial effect
Pipe fitting boring cutter of the present utility model, by the drill bit of a clamping fragment is set, thereby after perforate, moves on cutter head and can together take out carrying fragment, without manually manually reaching, very easy to use again.
Brief description of the drawings
Fig. 1 is the structural representation of the not perforate of pipe fitting boring cutter of the present utility model;
Fig. 2 is the cutaway view of A-A in Fig. 1;
Fig. 3 is the structural representation after the perforate of pipe fitting boring cutter;
In figure, 1 is that housing, 2 is that knife rest, 3 is that drill bit, 4 is that annular cutter head, 5 is that backstay, 6 is that spring, 7 is that holding screw, 8 is that step through-hole, 9 is that handgrip, 10 is that chip-removal hole, 11 is fixed support.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
A kind of pipe fitting boring cutter as described in Fig. 1-Fig. 3, comprises housing 1 and knife rest 2; Described knife rest 2 includes the drill bit 3, annular cutter head 4, backstay 5, spring 6 and the holding screw 7 that are arranged in housing 1; Described drill bit 3 is arranged on the axle center of annular cutter head 4 belows, the periphery of described drill bit 3 includes a horizontal step through-hole 8, described drill bit 3 can be holed to pipe fitting, and described backstay 5, spring 6 and holding screw 7 are all arranged in step through-hole 8, and fixing by holding screw 7; Described spring 6 is arranged between backstay 5 and holding screw 7, and one end of described backstay 5 is the outside of holding and lead to drill bit 3, and the other end contacts with spring 6, in the time of work, is used for fragment to carry out clamping.
Described housing 1 comprises handgrip 9, and this handgrip 9 facilitates staff to help in use pipe fitting boring cutter, in described handgrip 9, is provided with chip-removal hole 10, comminuted powder directly can be discharged by chip-removal hole 10, therefore can not stop up housing 1.
The material of described housing 1 is aluminium alloy, by aluminium alloy, dispels the heat very convenient.
Described backstay 1 is a steel ball.
The fixed support 11 of an arc structure is arranged at the bottom of described housing 1, facilitates pipe fitting boring cutter to locate on pipe fitting by fixed support 11.
When work, drive drill bit 3 and annular cutter head 4 to move down on knife rest 2, drill bit 3 and annular cutter head 4 are holed and smear metal to pipe fitting respectively, after boring completes, described drill bit 3 continues to move down, make backstay 5 touch transverse shifting after the fragment that needs smear metal, after the position of backstay 5 is lower than fragment, thereby described backstay 5 rebounds and blocks fragment under the effect of spring 6, now annular cutter head 4 also completes smear metal work, while moving on last knife rest 2, described drill bit 3 drives the fragment after smear metal to move up and leaves the hole after pipe fitting smear metal, operation is very easy, without manually manually reaching again, very easy to use.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
