Description

Tubing groove milling drum

Technical field

The utility model relates to a kind of equipment for grinding, relates to a kind of tubing groove milling drum specifically.

Background technology

It mainly is to adopt a side of frame that the beaming roller of a pair of spacing is set for existing tubing groove milling drum, adorns the abrasive machine that a circulation abrasive band grinding head and opposite side are provided with on it; There is the workpiece backup plate front end of corresponding belt sanding head.There is following shortcoming in actual use in this equipment:

1, effect is low.In advance workpiece tentatively is polished on abrasive machine during operation and is similar to desired circular arc, can aim at belt sanding head grinding forming back and forth by operator's offhand then, do not become ground otherwise finish, if directly can damage the abrasive band or reduce the serviceability in abrasive band by belt sanding.

2, consumptive material height.Because of the abrasive band is a soft body, grinding has the metal pipe material of corner to be easy to damage, and needs often to change.

3, the tubing grinding quality is poor.From the grinding in the abrasive band newly enabled, abrasive band when grinding performance reduces, the mouth of pipe radian that is processed has error; For crossing thin or blocked up tubing, grinding can't be carried out in this abrasive band, crosses thin easy deformation or blocked up can not processing.

4, the range of work is little.If the caliber of the tubing of processing ground not round or non-standard tubing can't be processed, can only process its limited standard-sized mouth of pipe.

The utility model content

The purpose of this utility model is for addressing the above problem, and can carry out time processing, have the measured tubing groove of ground matter milling drum standard or off-gauge thin, thick-wall tube groove and provide a kind of.

For achieving the above object, this novel technical solution is finished like this.A kind of tubing groove milling drum, comprise frame and the horizontal travelling table that is provided with thereof, be provided with this horizontal travelling table and vertically move workbench, with on frame, be provided with grinding attachment, wherein at the described driving mechanism that is provided with control workpiece parallel movement in a curve on the workbench that vertically moves; The fixedly connected eccentric stiffener of the output shaft of this driving mechanism; This eccentric stiffener is by the support arm of the hinged swing of eccentric shaft, the hinged indexing mechanism that has anchor clamps on the support arm top; With the grinding wheel that on frame, is provided with the corresponding anchor clamps of level.When control during driving mechanism, drive support arm and have the indexing mechanism of anchor clamps by eccentric stiffener, make the workpiece on its anchor clamps, do parallel movement in a curve along grinding wheel.The relative grinding wheel of workpiece moves back and forth and once can grinding go out needed tubing groove like this.

In this was novel, related driving mechanism was a pair of sprocket wheel that is provided with by spacing that adopts, and a chain is installed on it; Wherein a sprocket wheel is provided with rocking handle.Do reciprocal half cycle motion by the control rocking handle like this, the output shaft that drives on it is done the half cycle motion.

In this was novel, related driving mechanism can also adopt driving gear and driven gear, moves the direction unanimity for keeping two gears, and Jie's gear is set between two gears; Wherein on master gear, be provided with rocking handle.

In this was novel, related eccentric stiffener had the eccentric rocking arm of a T-shape groove, and the slide block and an alignment pin of eccentric shaft can be regulated and have to installation one in its T-shape groove.By adjusting slide block along the position in the T-shape groove of eccentric rocking arm, the grinding that comes the corresponding selection different tube diameters.

The good effect that the utlity model has is: because of having adopted the anchor clamps of parallel movement in a curve, make the workpiece on it do parallel movement in a curve along grinding wheel, can a grinding just can reach requirement like this, have the working (machining) efficiency height; Simultaneously.Because of the grinding wheel of its usage level setting carries out grinding, long service life not only, and can satisfy standard or off-gauge thin-walled or thick-wall tube, and the scope of different tube diameters grinding;

In addition, this design organization can satisfy the processing of multiple tubing groove, and the yield rate height.

Description of drawings

Fig. 1 is this novel structural representation;

Fig. 2 is another embodiment of Fig. 1 driving mechanism.

The specific embodiment

Below in conjunction with accompanying drawing embodiment, to this novel being further described.The accompanying drawing of giving only is to be used for reference and explanation usefulness, is not to be used to limit the utility model scope.

By tubing groove milling drum shown in Figure 1, it has a frame 11.This frame 11 is provided with horizontal travelling table 21 and its and goes up and install one and vertically move workbench 17, and controls the rocking handle 12 that vertically moves movable workbench.The described integral body of workbench 17 that vertically moves is at horizontal travelling table 21 top offsets.Be fixed with a riser 13 on the workbench 17 described vertically moving, be provided with sprocket wheel 9 and sprocket wheel 7 and this sprocket wheel 9 along the length direction of riser 13 by spacing and be provided with rocking handle 10, on two

sprocket wheels

9 and 7, chain 8 is housed; On this

sprocket wheel

9 and 7, be respectively equipped with the driving mechanism of the output shaft 28 and 28 ' composition that is connected.Fixedly connected a pair of

eccentric rocking arm

16 and 24 with 28 ' one ends at the output shaft 28 of riser 13 opposite sides.Have the T-shape groove respectively on this off-

centre rocking arm

16 and 24,

adjustable slide block

15 and 22 are installed in it; On described

slide block

15 and 22, be respectively equipped with

eccentric shaft

19 and 25 and the eccentric stiffeners formed of alignment pin 14 and 23.Described

eccentric rocking arm

18 and 27 oscillating quantity size, the displacement by adjusting

slider

15 and 22 decides, after regulating by

alignment pin

14 and 23 location.The corresponding lower end that is fixed with vertically disposed

support arm

18 and 27 on this

eccentric shaft

19 and 25; This

support arm

18 and 27 top are by bearing pin 26 and 26 ' hinged one division mechanism 5; Be arranged with anchor clamps 2 on this indexing mechanism 5, be connected on the locating piece 6 by passing a leading screw 3 with bidirectional helical of rocking handle 4.The anchor clamps 2 of control symmetry inwardly or are outwards dehisced synchronously or are closed when shaking leading screw 3.On a side frame 11 of indexing mechanism 5, be provided with the grinding wheel 1 of a drive head.This grinding wheel 1 is for being horizontally disposed with and corresponding with anchor clamps 2.Described indexing mechanism 5 has the one division base, and index dial is housed on it, is provided with scale on this index dial.

Fig. 2 has provided another embodiment of driving mechanism.It has has made corresponding variation on the architecture basics of Fig. 1, promptly be provided with driving gear 29 and driven gear 31 on riser 13, and be provided with intermeshing Jie's gear 30 between two gears; On this driving gear 29, be provided with rocking handle 13.Can guarantee that so main, driven gear 29 is consistent with 31 rotation direction, reach same sprocket wheel, the same driving purposes of chain.

The operation principle of this tubing groove milling drum: earlier processed tubing is placed on clamping and positioning on the anchor clamps 2, determines the angle of processing by indexing mechanism; Can control at this moment and drive

eccentric rocking arm

16 and 24 when rocking handle 10 rotates by the up time direction synchronously by the 5 parallel camber line displacements of up time swing control indexing mechanism, make the relative grinding wheel 1 of workpiece on it finish a movement in a curve, promptly by tubing arc port grinding one end from top to bottom; When otherwise control 10 inverse time of rocking handle direction is rotated, i.e. direction grinding from the bottom to top.Therefore, the driving mechanism that is adopted, eccentric stiffener are to implement this novel key.
