Abstract
The invention relates to a floating cutter disc for a pipe fitting groove, which has the beneficial effects that a chamfer cutter of the floating cutter disc and a supporting and positioning frame are installed on a radial sliding block cutter rest; the sliding block cutter rest can radially and freely slide on the cutter disc; and spring force is applied onto the lower part of the sliding block cutter rest, so that the supporting and positioning frame is kept to compress the inner wall of a pipe fitting, thereby achieving the effect of taking the inner wall of the pipe fitting as a processing benchmark and ensuring the consistency of the pipe fitting groove angle and blunt edge thickness.
Description
Technical field
The present invention relates to the cutterhead of machined steel pipe fitting bevel for welding.
Background technology
At present, what existing cutterhead adopted is fixed structure, during the processing pipe fitting, relatively rotate between cutter and the workpiece, and certain with the centre of gyration apart from maintenance; Outside diameter tolerance is bigger in the pipe fitting groove after the processing; Can not satisfy the requirement of standard root face size; And bevel angle, root face height play a decisive role in the pipe fitting welding; Pipe fitting welding procedure size is benchmark with the pipe fitting inner wall, and the compact dimensions of pipe fitting is to be benchmark with the pipe fitting axial line, is that the stationary knife processing method of machining benchmark is unreasonable so adopt with the centre of gyration.
Summary of the invention
When processing the pipe fitting groove, be difficult to control outside diameter tolerance in the groove in order to overcome the existing fixed cutterhead; Can not satisfy the deficiency of standard root face dimensional requirement; The present invention provides a kind of pipe fitting groove cutterhead that floats; It is the processing mode of benchmark that this pipe fitting groove floats that cutterhead adopted with the pipe fitting inner wall, can satisfy the pipe fitting groove dimensional requirement after the processing.
The technical solution adopted for the present invention to solve the technical problems is: the cutterhead of the unsteady cutterhead of pipe fitting groove is provided with chute; Be provided with the slide block knife rest in the chute; Slide block knife rest two ends are respectively equipped with straight angle cutter and rose reamer; Near the rose reamer slide block knife rest place is provided with the support locating rack, and a near end of the slide block knife rest the straight angle cutter links to each other with spring, and spring and cutterhead are fixedly linked.
A kind of prioritization scheme of such scheme is: described chute is a dovetail groove.
The another kind of prioritization scheme of such scheme is: the support locating rack is a pyramidal structure.
The invention has the beneficial effects as follows; Rose reamer and support locating rack are contained on the radial slider knife rest; The slide block knife rest can radially be free to slide on cutterhead, adds a spring force in slide block knife rest bottom, makes the support locating rack keep compressing pipe fitting inner wall; Thereby playing with the pipe fitting inner wall is the effect of machining benchmark, has guaranteed pipe fitting bevel angle, root face height uniformity; The knife rest back-up block is set to pyramidal structure, has guaranteed that it contacts with the mouth of pipe is that point contacts to improve the effect of machining accuracy.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a structural representation of the present invention.
1. cutterheads among the figure, 2. dovetail groove, 3. slide block knife rest, 4. straight angle cutter, 5. rose reamer, 6. support locating rack, 7. spring.
The specific embodiment
In Fig. 1; The cutterhead 1 of the unsteady cutterhead of pipe fitting groove is provided with dovetail groove 2; Be provided with slide block knife rest 3 in the dovetail groove 2, slide block knife rest 3 two ends are respectively equipped with straight angle cutter 4 and rose reamer 5, and near slide block knife rest 3 places the rose reamer 5 are provided with the support locating rack 6 of taper; Near one end of the slide block knife rest 3 the straight angle cutter 4 links to each other with spring 7, and spring 7 is fixedly linked with cutterhead 1.
Claims (3)
1. the pipe fitting groove cutterhead that floats; It is characterized in that: cutterhead is provided with chute; Be provided with the slide block knife rest in the chute, slide block knife rest two ends are respectively equipped with straight angle cutter and rose reamer, and near the slide block knife rest place the rose reamer is provided with the support locating rack; Near one end of the slide block knife rest the straight angle cutter links to each other with spring, and spring and cutterhead are fixedly linked.
2. the pipe fitting groove according to claim 1 cutterhead that floats, it is characterized in that: described chute is a dovetail groove.
