Above-mentioned main shaft is a hollow shaft, be provided with mandrel and core sleeve in the axle, be provided with handwheel with core sleeve's thread connection, handwheel links by bearing and body, be provided with between core sleeve and the body and limit the two and make retainer in relative rotation, in an end core sleeve of mandrel, be arranged with and make axially movable moving axis cover with mandrel, be provided with the retainer that a restriction moving axis cover rotates between moving axis cover and the core sleeve, be provided with fixture block and support thereof more than three groups or three groups, the fixture block support is made of two rod members that are hinged at the middle part, one rod member, one end and moving axis cover are hinged, the other end and workpiece fixture block are hinged, another rod member one end and core sleeve are hinged, and the other end is hinged with the bearing pin that is located in the workpiece fixture block guide groove.
The above-mentioned feed tooth number of teeth is 1, and the withdrawing tooth number of teeth is 2～5.
Because the utility model compact conformation, volume are little, are easy to carry, and are particularly suitable for the bevel for welding that maintenance sites is cut pipeline-like part.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
Referring to accompanying drawing, the utility model comprises motor 4, body 2, transmission mechanism, delivering gear and workpiece grip mechanism 9, motor 4 is given main shaft 6 through gear drive 3 with transmission of torque, be fixedly connected with revoliving arm 8 on the main shaft 6 with gathering sill 20, revoliving arm 8 be provided with can be in gathering sill 20 along the tool rest 22 of the radially reciprocating clamping cutter 21 of main shaft 6, be provided with advance and retreat cutter drive shaft 24 with tool rest 22 thread connection, advance and retreat cutter drive shaft 24 connects with the bearing block 23 that connects firmly on revoliving arm by bearing, on the rotary track that main shaft 6 rotates, be provided with feed tooth 25 and withdrawing tooth 27 at power transmission shaft 24, feed tooth 25 and withdrawing tooth 27 are located at can be along on the main shaft 6 axially movable braces 28, and advance and retreat cutter drive shaft 24 is provided with and feed tooth 25 or withdrawing tooth 27 meshed gears 26.
Above-mentioned main shaft 6 can be made as hollow shaft, be provided with mandrel 11 and core sleeve 7 in the axle 6, be provided with handwheel 1 with core sleeve's 7 thread connection, handwheel 1 links by bearing 30 and body 2, be provided with between core sleeve 7 and the body 2 and limit key or the pin that the two is made retainer in relative rotation 5 as embeds the axle sleeve axial groove, in an end core sleeve 7 of mandrel 11, be arranged with mandrel 11 and make axially movable moving axis cover 10, be provided with key or pin that a restriction moving axis overlaps 10 retainers that rotate 12 as embeds the axle sleeve axial groove between moving axis cover 10 and the core sleeve 11; Clamping the utility model of the pipe fitting that is difficult to clamping for the ease of the bigger pipe fitting of line up diameter and outer wall can adopt internal expanding type workpiece grip mechanism 9: be provided with three groups or three groups of above fixture blocks 17 and support 14 thereof, fixture block support 14 is made of two rod members 13,15 that are hinged at the middle part, it is 10 hinged that one rod member, 13 1 ends and moving axis overlap, the other end and workpiece fixture block 17 are hinged, another rod member 15 1 ends and core sleeve 7 are hinged, and the other end is hinged with the bearing pin 18 that is located in the workpiece fixture block guide groove 16.
Above-mentioned feed tooth 25 numbers of teeth are 1, and withdrawing tooth 27 numbers of teeth are 2～5.
During the utility model work, the clamping device 9 of this beveling machine is stretched in the mouth of pipe of workpiece to be processed, rotation mandrel 11, because core sleeve 7 and mandrel 11 thread connection, and and the retainer 5 that restricted core sleeve 7 rotates between the body 2, thereby core sleeve 7 is motionless, mandrel 11 drives 10 motions of moving axis cover, limited the rotation of moving axis cover 10 because of retainer 12, moving axis cover 10 can only move axially at this moment, two rod members 13 of fixture block support 14 under the effect of moving axis cover 10,15 rotate in opposite directions around its middle part pin joint 19, and workpiece is clamped, and the while also is fixed on this machine one end of workpiece.Rotate handwheel 1, because of clamping device is fixed core sleeve 7 with workpiece, handwheel 1 promotes body 2 and moves axially (having limited the rotation of body 2 because of retainer 5), the Working position that makes cutter 21 be positioned at workpiece gets final product starter motor 4, motor 4 is given main shaft 6 through gear drive 3 with transmission of torque, main shaft 6 just drives revoliving arm 8, tool rest 22 and cutter 21 rotations, thereby realizes the cutting to workpiece.Feed or withdrawing: pulling or promotion braces 28, feed tooth 25 or withdrawing tooth 27 and the gear 26 of advance and retreat cutter drive shaft 24 are meshed, and it is braces 28 is fastening with trip bolt 29, when tool rest 22 rotates with main shaft 6, advance and retreat cutter drive shaft 24 whenever rotates a circle around main shaft 6 and all will once rotate with feed tooth 25 or 27 effects of withdrawing tooth, because of this power transmission shaft 24 and tool rest 22 thread connection, tool rest 22 is just realized autofeed or withdrawing along main shaft 6 radial motions in the gathering sill 20 at revoliving arm 8 under the effect of power transmission shaft 24.
