The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail, but not as to restriction of the present utility model.
Fig. 1 is the structural representation of perforated pipe machine for removing bur of the present utility model; Fig. 2 is the A portion enlarged drawing of Fig. 1.As depicted in figs. 1 and 2, the perforated pipe machine for removing bur comprises along track 4 straight-line railcars 1, and the support arm 6 parallel with track 4 fixedly arranged on the railcar 1.The front end of support arm 6 is connected with rotating driving device 5.On the rotating driveshaft 51 of rotating driving device 5 cutter 7 is arranged fixedly.
Fig. 3 is the schematic cross-section of the cutter part of perforated pipe machine for removing bur of the present utility model.In conjunction with Fig. 1, Fig. 2 and Fig. 3, cutter 7 comprise with the fixing tool rest 701 of rotating driveshaft and with tool rest 701 eccentric at least one hinged eccentric cutter 702.The number of eccentric cutter 702 can be determined according to actual conditions.General eccentric cutter 702 is two and gets final product that two eccentric cutter 702 axial symmetry are arranged on the tool rest.
Preferred as above-described embodiment, the blade 721 of eccentric cutter 702 is curved, and an end of eccentric cutter 702 has pin-and-hole 723, is used for bearing pin 703 and passes, and it is articulated on the tool rest 701.End face at eccentric cutter 702 end relative with hinged end forms blade 722, and blade 722 is axially consistent with perforated pipe 3.
Tool rest 701 comprises central tube 711 and the chassis 712 that circumferentially extends to form along an end of central tube 711, and the other end of central tube 711 is provided with block plate 704.Eccentric cutter 702 is articulated between block plate 704 and the chassis 712 by bearing pin 703.One end of bearing pin 703 is threaded with chassis 712, because the existence of central tube 711 makes the space that forms ccontaining eccentric cutter 702 between block plate 704 and the chassis 712.Perhaps bearing pin 703 passes block plate 704, eccentric cutter 702 and chassis 711, is provided with split pin 5 at an end of bearing pin 703, makes things convenient for bearing pin 703 dismountings.Bolt by axial setting is with block plate 704 and tool rest 701 relative positionings.At this moment, the end of rotating driveshaft 51 is formed with step, and the inboard of tool rest 701 is stuck in the step place, and the outside contacts with block plate 704, and bolt is threaded with rotating driveshaft 51, applies axial force for block plate 704, makes block plate 704 and tool rest 701 relative fixed.In order to guarantee the circumferential location of tool rest 701 and rotating driveshaft 51, correspondence has keyway 11 on central tube 711 and rotating driveshaft 51, cooperates the circumferential location of realizing tool rest 701 and output shaft with key by keyway.
As preferably, block plate 704 has the detent of ccontaining central tube 711 ends.Can make block plate 704 and tool rest 701 assemble the location fast.The another kind of mode that block plate 704 and tool rest 701 can be assembled fast can adopt block plate 704 to be threaded with central tube 711.
Fig. 3 is the end view of the centralizer part of perforated pipe machine for removing bur of the present utility model.In conjunction with Fig. 1, Fig. 2 and Fig. 3, ring flange 205 is arranged fixedly on the rotating driving device 5.The centralizer 2 that is arranged on the rotating driving device 5 is fixing with ring flange 205.Centralizer 2 comprises first positioning disk 204 and second positioning disk 207 that is oppositely arranged, the middle part of first positioning disk 204 and second positioning disk 207 has the through hole that the machine for removing bur unit head passes, connect by four guiding ribs 206 between first positioning disk 204 and second positioning disk 207, article four, guiding rib 206 all is the arc of evagination, and four guiding ribs 206 protrude from the outer rim of first positioning disk 204 and second positioning disk 207 diametrically.Guiding rib 206 operated by rotary motion 3-4 bars are comparatively suitable.Certainly, the 5-6 bar is set even more guiding ribs also are fine.Has the hole 203 that bolt passes on first positioning disk 204, in order to fixedly connected with ring flange 205 by bolt.Guiding rib 206 and first positioning disk 204 and second positioning disk 207 can be that to weld also can be that screw fixedly waits other modes to be connected.
As preferably, guiding rib 206 upwards evenly distributed in week.Centralizer can be the shape of rule like this, is convenient to assembling and use, and sets upright effective.The two ends of guiding rib are formed with blade 210, to chip the iron filings of piling up in the perforated pipe, reduce the resistance of unit head advance and retreat.
Preferred as another, first positioning disk 204 is corresponding with the structure of second positioning disk 207.The tie point of first positioning disk 204 and guiding rib 206 to the distance at center greater than the distance of the outer rim between the two adjacent tie points to the center.Equally, the tie point of second positioning disk 207 and guiding rib 206 to the distance at center greater than the distance of the outer rim between the two adjacent tie points to the center.Its implication be guarantee between adjacent two tie points bigger gap to be arranged in case iron filings from this slit by and do not stop centralizer.When making, the part between the tie point pruned to get final product.Preferable structure is the curved indent of outer rim between the two adjacent tie points on first positioning disk 204.Equally, the curved indent of outer rim between the two adjacent tie points on second positioning disk 207.Not only can increase the gap between two tie points, and the structure of positioning disk is enough stable.
The utility model middle orbit car is electric motor car.Rotating driving device is air motor.Support arm is the rigidity body that source of the gas is provided for air motor.
Above embodiment is exemplary embodiment of the present utility model only, is not used in restriction the utility model, and protection domain of the present utility model is defined by the claims.Those skilled in the art can make various modifications or be equal to replacement the utility model in essence of the present utility model and protection domain, this modification or be equal to replacement and also should be considered as dropping in the protection domain of the present utility model.
