Accompanying drawing explanation
Schematic diagram when accompanying drawing 1 is a kind of means for removing burr from external integral key deburring of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of means for removing burr from external integral key of the present invention is described further.As shown in Figure 1, a kind of means for removing burr from external integral key, comprise frame 1, described frame 1 is fixed with driving box 2, described driving box 2 is provided with drive workpiece 30 to rotate front top 3, described front top 3 are driven by driving box 2, the general name of top 3 devices rotated before namely described driving box 2 drives, casing internal fixtion has motor, or prime mover of other exportable gyration, front top 3 are rotatably connected on casing, and be connected with the motor in casing or prime mover, before motor or prime mover driven, top 3 rotate, in order to simplify the structure of means for removing burr from external integral key, the described front axis of top 3 is parallel with the upper surface of frame 1,
See Fig. 1, described frame 1 is also provided with tailstock 4, this tailstock 4 structure is identical with tailstock 4 structure of the prior art, described tailstock 4 is fixed with back centre 5, the axis of described back centre 5 and the front axis coaxle of top 3, described back centre 5 can stretch along the front axis of top 3, so that the clamping of workpiece 30, described tailstock 4 is fixed with the driving cylinder 12 driving back centre 5 flexible; Described tailstock 4 is also fixed with and will tailstock 4 is had to be locked at locking device on guide rail 6, described locking device can be lock-screw 11, described locking device also can be that locking mechanism conventional on tailstock 4 in prior art substitutes, tailstock 4 does not need to bear too large active force in deburring process, therefore, tailstock 4 is locked on guide rail 6;
See Fig. 1, described tailstock 4 is slidably connected in frame 1, described frame 1 is fixed with the guide rail 6 that tailstock 4 can be made to slide, and frame 1 is fixed with two guide rails, 6, two guide rails 6 and is all fixed in frame 1 by hold-down screw 15;
See Fig. 1, drive motors 7 is provided with in the frame 1 between sinciput point 3 and back centre 5, described drive motors 7 is provided with the bristle brush wheel 8 removing burr on workpiece 30, drive motors 7 between front top 3 and back centre 5 can be one, also can be two, can also be more than two, Ru Sitai, six etc.;
In order to improve the deburring efficiency of means for removing burr from external integral key, two drive motors 7 are provided with between described front top 3 and back centre 5, two drive motors 7 are equipped with bristle brush wheel 8, the bristle brush wheel 8 be positioned on two drive motors 7 is arranged about the front axisymmetrical of top 3, that is, same external splines has two bristle brush wheels 8 to carry out deburring process to it simultaneously; The vertical height of described bristle brush wheel 8 upper surface is higher than the vertical height of front top 3 axis, and that is, the upper surface of bristle brush wheel 8 is greater than the distance of front top 3 axis to frame 1 upper surface to the distance of frame 1 upper surface; In deburring process, bristle brush wheel 8 is larger with the contact area of external splines, the efficiency of deburring is higher, in order to make bristle brush wheel 8 uniform force, symmetrical plane in bristle brush wheel 8 short transverse and the front dead in line of top 3, above the symmetrical plane in bristle brush wheel 8 short transverse to bristle brush wheel 8, the distance of table, bristle brush wheel 8 lower surface is equal;
When there is an external splines one end of workpiece 30, two drive motors 7 claimed about front top 3 axis can be set, see Fig. 1, when workpiece 30 two ends all have external splines, four drive motors 7 claimed about front top 3 axis can be set, when drive motors 7 has an even number platform, means for removing burr from external integral key has higher deburring efficiency, certainly, drive motors 7 also can have odd number platform, and that is, same external splines only has a bristle brush wheel 8 to carry out deburring process to it, when adopting single bristle brush wheel 8 deburring, the efficiency of means for removing burr from external integral key reduces;
See Fig. 1, a drive motors 7 tackles a bristle brush wheel 8, and namely each bristle brush wheel 8 drives by independent drive motors 7, bristle brush wheel 8 comprises bristle, due to the existence of bristle, bristle brush wheel 8 can produce elastic deformation, thus makes bristle brush wheel 8 can adapt to the external splines of more sizes; Certainly, the bristle brush wheel 8 of different-diameter can also be changed to the external splines making means for removing burr from external integral key can adapt to more sizes; By changing the position of drive motors 7, bristle brush wheel 8 can also be made to adapt to the external splines of more sizes, as drive motors 7 is fixed in frame 1 by the slide carriage that can slide in frame 1, and this slide carriage should be arranged locking body, to lock slide carriage;
See Fig. 1, the gripper shoe 9 supporting workpiece 30 is also fixed with between described front top 3 and back centre 5, the quantity of described gripper shoe 9 does not limit, described gripper shoe 9 lower end is fixed with the base 13 be connected with frame 1, described base 13 is integral type structure with gripper shoe 9, described base 13 is bolted in frame 1, and described gripper shoe 9 upper end offers the groove 14 holding workpiece 30; At the limited block 10 being also fixed with restriction tailstock 4 extreme position away from front one end of top 3 in described frame 1, limited block 10 can be fixed in frame 1 by any mode.
The workpiece 30 with spline is generally axial workpiece, and in frame 1, fixed support plate 9 can avoid axial workpiece to bend, and improves the stability of workpiece 30 when deburring, in specific implementation process, workpiece 30 adopts front top 3, back centre 5 clamps, front top 3 is the initiatively top effect played drive workpiece 30 and rotate, frame 1 is also fixed with drive motors 7, bristle brush wheel 8 rotates under the drive of drive motors 7, external splines contacts to produce with bristle brush wheel 8 and weares and teares, thus reach the effect of removing burr on external splines, bristle brush wheel 8 i.e. bristle brush wheel 8 of the prior art, bristle brush wheel 8 can produce certain elastic deformation, the burr on external splines is removed relative to the method adopting cutter to engage with external splines in prior art, technical scheme disclosed by the invention has good versatility.
These are only the preferred embodiment of the present invention, being intended to embody outstanding technique effect of the present invention and advantage, is not the restriction to technical scheme of the present invention.Those skilled in the art will appreciate that all amendments made based on the technology of the present invention content, change or substitute technology feature, all should be covered by the technology category of claims of the present invention opinion.
