Abstract

A floating cutter head for processing the port of a steel tube relates to a tool-holder component on a steel tube. A tool apron installation socket is arranged on the center of a base plate. The tool apron for a flat-headed cutter is fixed on one end of the installation socket. The edge of the flat-headed cutter is parallel to a chassis in radial direction. The floating tool apron for a spring squeezer is installed on the other end of the tool apron installation socket. A combined chamfering knife is installed on the tool apron installation socket that forms a tangency angle with the inside-and-outside periphery of the port of the processed steel tube. A roller is installed on the tool apron installation socket. The roller and the peripheral surface of the port of the processed steel tube have joint operation. When the port of the steel tube is processed by the utility model, the roller rotates around the periphery of the port of the steel tube. The floating tool apron of the cutter head floats in the diameter direction caused by the change of the outside diameter of the tube. The flat-headed cutter and a combined chamfering tool are kept to be close to the flat end of the steel tube and the inside-and-outside port of the steel tube in a correct tangential position, thus ensuring the good quality of the flat-headed port of the steel tube and the combined chamfering.

Description

The unsteady cutterhead of steel pipe port processing

Technical field

The utility model belongs to the metal cutting equipment technical field, relates to a kind of cutter holder parts on the facing-machine.

Background technology

Existing facing-machine, the turning cutting tool of its tack and chamfered edge all are fixedly mounted on the cutterhead, work in-process, if the concentricity of cutterhead and steel pipe is adjusted well inadequately, or the circularity of steel pipe is not up to standard, and then the quality of steel pipe chamfered edge is just relatively poor or defective.

Summary of the invention

The purpose of this utility model provides a kind of chamfering machine cutterhead of new structure, when processing has the steel pipe of certain ovality, or when the concentricity of cutterhead and steel pipe is adjusted well inadequately, can regulate the relative position of cutter and steel pipe port automatically, guarantee that chamfered edge is accurate.

The technical scheme that realizes above-mentioned purpose is: radially offer the tool rest mounting groove at the middle part, chassis, the tack cutter that is connected with knife bar fixedly tool rest is fixedly installed in an end of tool rest mounting groove, and the blade of tack cutter is radially paralleled with the chassis, the unsteady tool rest of band spring compression device then is installed at the other end of tool rest mounting groove, pass through knife bar on the unsteady tool rest, pressure strip is separately installed with the inside and outside chamfered edge cutter that becomes certain tangent angle with the interior neighboring of processed steel pipe port with screw, on the tool rest that floats also by installing and the fit running roller of running of processed steel pipe port outer peripheral face to paralleling and being fixed in rolling axle on the tool rest that floats with chassis axle.

The utility model adds man-hour to the steel pipe port, running roller rotates along steel pipe port side face, the unsteady tool rest of cutterhead is along with the variation of tube outer diameter produces floating on the diametric(al), the close contact and accurate tangent position that remains tack cutter, inside and outside chamfered edge cutter and steel pipe Ping Kou, interior external port, thus guarantee the good quality of the tack and the inside and outside chamfered edge of steel pipe port.

Description of drawings

Accompanying drawing 1 is the structural representation of facing of the present utility model.

Accompanying drawing 2 is that the A-A of accompanying drawing 1 is to the sectional structure schematic diagram.

The specific embodiment

1 middle part, chassis radially offers swallow-tail form or T shape tool rest mounting groove 2, and fixedly tool rest 25 is fixedly installed in an end of chassis tool rest mounting groove 2, and the tool rest 26 that floats is slidably mounted on the other end of chassis tool rest mounting groove 2.The tack cutter is made up of knife bar 3, blade 4, blade keeping plate 6 and pressure strip screw 7, knife bar 3 is fixed in fixedly on the tool rest 25 by chute adjustment screw 5, knife bar 3 and fixedly be provided with pad 34 between the tool rest 25, be fixed in the position of the blade 4 on the knife bar 3 with adjustment, and the blade of blade 4 is paralleled with 1 sagittal plane, chassis.Outer chamfered edge cutter is made of knife bar 13, outer chamfered edge blade 14, pressure strip 15, hold-down screw 12, interior chamfered edge cutter is made of interior chamfered edge blade 20, pressure strip 21, hold-down screw 22 and knife bar 23, the cutting edge of inside and outside chamfered edge blade (20), (14) respectively with cutter axis angle at 45, the interior neighboring chamfer angle at 45 of promptly processed steel pipe port.Outer chamfered edge knife bar 13 and interior chamfered edge knife bar 23 are fixed on the knife bar mount pad 17 with hold-down screw 32,33 respectively, also be separately installed with pad 9,18 between interior chamfered edge knife bar 23, outer chamfered edge knife bar 13 and the knife bar mount pad 17, with the cutting depth of chamfered edge cutter in adjusting and outer chamfered edge cutter.The rolling axle of running roller 16 also is fixed on the knife bar mount pad 17 simultaneously, and the axis of this rolling axle parallels with cutter axis.Knife bar mount pad 17 is fixedly connected with unsteady tool rest 26 by screw 10, pin 11.And the spring compression device 19 of the tool rest 26 that floats is slotted eye 27, spring 28, spring axostylus axostyle 30 to be installed, to be reached the holding screw 31 that the screw hole by spring compression piece 29 is connected with spring axostylus axostyle 30 with the fixedly connected spring compression piece 29 in chassis 1 and constituted by a pair of spring that tool rest 26 outboard ends that float are offered.

Unsteady tool rest design of the present utility model has fundamentally solved invar pipe 8 and has had ovality, or has concentricity between steel pipe fixture 24 and the cutterhead and the inside and outside chamfered edge problem off quality that causes.In addition, tack blade 4 of the present utility model, outer chamfered edge blade 14 and interior chamfered edge blade 20 all adopt measure-alike rectangle not have cutting edge blade, not only help improving the shock resistance of blade, and can exchange, and it is all convenient to manipulate and keep in repair.
