Description
Technical field
The utility model relates to cutting tool, is specifically related to a kind of cutter processing header pipe joint groove.
Background technology
The critical component that header is boiler pressure-containing member fluid dispersion and collects is the connector of manifold systems.Header pipe joint is used for header and heating surface pipe is welded to connect.In order to ensure welding quality, header pipe joint needs process bevel for welding.At present, the retaining wall on slope of header pipe joint adopts the mode of lathe turning to carry out, but due to the requirement on machining accuracy of groove not high, really waste one's talent on a petty job with lathe process, because the chip time is shorter, and for time much larger than the chip time loaded and unloaded on chuck and align, thus causing processing cost high, production efficiency is low.
Utility model content
One of the technical problems to be solved in the utility model pin is to above-mentioned defect, provides a kind of cutter processing header pipe joint groove, to reach the object raising the efficiency and reduce production cost.
In order to solve the problems of the technologies described above, the utility model provides a kind of header pipe joint bevel machining cutter of following structure, comprises knife bar, knife bar is connected with topping machanism; Described topping machanism comprises the knife rest for being connected with knife bar, knife rest is provided with plug-in opening, plug-in opening is built with cutting knife and cutting knife pad, and cutting knife pad, between cutting knife and knife bar, knife rest is bolted with the puller bolt that can probe into and be fixedly connected with knife rest by cutting knife in plug-in opening; The lower end of knife bar is connected with can inlet/outlet pipe coupler bore the centring means adapted with the aperture of pipe joint endoporus.
In order to improve working (machining) efficiency, described topping machanism is two covers, and two overlap topping machanisms separation knife bar both sides and eccentric setting, and the eccentric direction of two cover topping machanisms is different.
For the ease of cutting knife installation and prevent cutting knife from rotating, described plug-in opening is square hole, and described cutting knife comprises the cutter body in strip, and the lower surface of cutter body offers cutting edge, and cutting edge is outer low and inner high skewed setting.
For the ease of being connected with drilling machine, the upper end section of described knife bar for having the shank section of Morse's taper, bottom section is knife rest connecting portion.
In order to structure simply realizes centring means, described centring means comprises the mandrel being connected to knife bar lower end, and mandrel is equipped with positioning sleeve.
In order to the wearing and tearing of positioning sleeve, reduce described positioning sleeve and be rotatably connected on mandrel.
For the ease of the endoporus of positioning sleeve positioning sleeve inlet/outlet pipe joint, the outer surface of described positioning sleeve is the high outer convex globoidal in low middle part, two ends.
Occupation mode of the present utility model is as follows: be connected with drilling machine by its knife bar by header pipe joint bevel machining cutter, drilling rod drives bevel machining cutter to rotate, driving drilling rod moves down, the centring means of process tool is introduced in the endoporus of pipe joint, play certralizing ability, along with drilling rod continues to move down, the cutting knife on knife rest can carry out retaining wall on slope to the end of the pipe joint of clamping on Drilling machines bench.By changing cutting knife pad, the distance between cutting knife and knife bar can be changed, to adapt to the pipe joint of various outer diameter; Equally, by changing centring means, the pipe joint of different inner diameters can be adapted to; Therefore the utility model can realize the retaining wall on slope of the pipe joint of multiple different tube diameters, adapts to face width.
The utility model has the advantage of: structure is simple, process velocity is fast, can realize the retaining wall on slope of the pipe joint of multiple different tube diameters, adapts to face width.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view along A-A line in Fig. 1;
Fig. 3 is the schematic diagram of another version of positioning sleeve.
Detailed description of the invention
As depicted in figs. 1 and 2, header pipe joint bevel machining cutter comprises knife bar 1, the upper end section of knife bar 1 for having the shank section 11 of Morse's taper, bottom section is knife rest connecting portion 12, shank section 11 is for the connection with drilling machine.The knife rest connecting portion 12 of knife bar 1 is connected with topping machanism; Described topping machanism comprises the knife rest 2 for being connected with the knife rest connecting portion 12 of knife bar 1, knife rest 2 is connected on knife rest connecting portion 12 by the mode of welding, knife rest 2 is provided with plug-in opening 3, plug-in opening 3 is built with cutting knife 4 and cutting knife pad 5, cutting knife pad 5 is between cutting knife 4 and knife bar 1, described plug-in opening 3 is set to square hole, cutting knife 4 comprises the cutter body in strip, the lower surface of cutter body offers cutting edge, cutting edge is outer low and inner high skewed setting, and cutting knife pad 5 is also the packet of strip.Knife rest 2 is bolted with the puller bolt 6 that can probe into and be fixedly connected with knife rest 2 by cutting knife 4 in plug-in opening 3, namely cutting knife 4 and cutting knife pad 5 insert after in plug-in opening 3, bolt 6 just can tightly withstand on cutting knife 4 by screwing bolts 6, thus realizes cutting knife 4 and cutting knife pad 5 fixing in plug-in opening 3.Topping machanism is two covers, and two overlap topping machanisms separation knife bar 1 both sides and equal eccentric setting, and the eccentric direction of two cover topping machanisms is different; Eccentric setting is carried out more particularly bright referring to Fig. 2, the both sides of two cover topping machanism separation knife bars 1 in Fig. 2, the center line 13 of a set of topping machanism in left side is positioned at the below in knife bar 1 axle center, the center line 14 of a set of topping machanism on right side is positioned at the top in knife bar 1 axle center, and namely two cover topping machanism bidirectional eccentrics are arranged.Two cover topping machanisms adopt the set-up mode of bidirectional eccentric, can shorten the arm of force that cutting knife is stressed, can reduce torque, both reduce the load of drilling machine, additionally reduce the stressed of cutting knife, are conducive to the service life extending cutting knife.
As shown in Figure 1, be connected with can inlet/outlet pipe coupler bore the centring means adapted with the aperture of pipe joint endoporus in the lower end of knife bar 1.Described centring means comprises the mandrel 7 being connected to knife bar 1 lower end, mandrel 7 is equipped with positioning sleeve 8, and positioning sleeve 8 can inlet/outlet pipe coupler bore and the diameter of the external diameter of positioning sleeve 8 and pipe joint endoporus adapt.The implication that the external diameter of positioning sleeve 8 and the diameter of pipe joint endoporus adapt is: positioning sleeve 8 and pipe joint endoporus are matched in clearance, the size in gap is rocked minimum for principle with the endoporus 10 and positioning sleeve 8 that do not affect the smooth inlet/outlet pipe joint 9 of positioning sleeve 8 in pipe joint, that is do not affect positioning sleeve 8 smoothly inlet/outlet pipe coupler bore when, gap is the smaller the better.Positioning sleeve 8 can be fixed on mandrel 7, but owing to can rotate with mandrel 7 when positioning sleeve 8 is fixed on mandrel 7, thus bring positioning sleeve 8 increased wear.In order to reduce the wearing and tearing of positioning sleeve 8, positioning sleeve 8 is preferably rotatably connected on mandrel 7.As shown in Figure 3, for the ease of positioning sleeve 8 inlet/outlet pipe coupler bore more smoothly, the outer surface of described positioning sleeve 8 is preferably set to the high outer convex globoidal 15 in low middle part, two ends.
