The spring tool that is used for the retainer deburring
The invention belongs to retainer surface quality manufacture field, relate to concretely a kind of spring tool for retainer deburring technique, be used for solving the multiaspect chamfering of retainer complexity, the deburring hard problem.
The shape of retainer is very complicated, need to bore the pocket hole of a lot of five equilibriums, the shape such as that this pocket hole has is square, cylindrical, circular cone; And five equilibrium is individual different from 4-200, and odd number is arranged, and even number is arranged.Size is pressed internal diameter and is calculated, from the 10-2500 millimeter.Generally speaking, the shape of retainer is an irregular part.And retainer is a strength member of bearing, and the quality of retainer determines the quality of bearing.Especially retainer surface deburring operation is the key technology difficult problem of domestic bearing enterprise, the especially technical barrier of world's bearing industry.The bearing technology personnel are not capturing this technological difficulties all the time.Usually technology is to use file and scraper, manually processes, and then uses the sand paper manual polishing, carries out at last the light decorations and processes.Efficient is very low, and has the risk of omitting, and labour cost goes up continuously in recent years, causes the cost of deburring very large.Retainer is starved of continuous research and development new technology, solves the technique bottleneck of surperficial deburring.
Summary of the invention
In order to address the above problem, patent of the present invention is to research and develop a kind of cutter arrangement for different retainer pocket pore structures, blade of the present invention is controlled by spring, can be in the process of deburring, according to varying in size of burr, soft or hard is different, distance is different, and automatic telescopic reaches the jagged burr of just removing, but automatically removing burr substitutes manually scrape burr fully.
To achieve these goals, technical scheme of the present invention is as follows:
The spring tool that is used for the retainer deburring, comprise buncher one, frame, rotating shaft, cutter structure, rotating disk and buncher two, the frame upper end is installed with buncher one, buncher one connection rotating shaft, driving cutter structure by rotating shaft rotates, the frame lower end is provided with rotating disk, the rotation of rotating disk is by buncher two controls of its underpart, it is characterized in that: described cutter structure comprises the handle of a knife that is connected with rotating shaft, fixed cutter body on the handle of a knife, cutter hub bearing spring, blade are connected on the spring, and cutter structure is done the rotating Vortex motion in company with rotating shaft.
Described cutter hub comprises the hierarchic structure of main body and main body lower end.
Further, evenly arrange on the described hierarchic structure and somely connect thereon blade by spring.
The most advanced and sophisticated angle of described blade is 45 °.
Advantage of the present invention: the present invention can remove different burrs according to the actual conditions of retainer, when irregular burr touches cutter, just begins to remove burr, burr varies, hard-soft, although situation is different, by spring control cutter, automatic telescopic, reach jagged and just remove burr, but automatically removing burr substitutes manually scrape burr fully, deburring is effective, and time saving and energy saving.

The specific embodiment
Specify technical scheme of the present invention below in conjunction with accompanying drawing.
The spring tool that is used for the retainer deburring, as shown in Figure 1, comprise buncher 1, frame 2, rotating shaft 3, cutter structure 4, rotating disk 5 and buncher 26, frame 2 upper ends are installed with buncher 1, buncher one 1 connection rotating shafts 3, drive cutter structure 4 by rotating shaft 3 and rotate, its rotation direction is according to clockwise direction or counter clockwise direction.
Be provided with rotating disk 5 in frame 2 lower ends, rigid bearing retainer on the rotating disk 5, the rotation of rotating disk 5 is by buncher 26 controls of its underpart, and the direction of rotation of its rotation direction and rotating shaft 3 is conducive to improve deburring efficient, boosts productivity.
Such as Fig. 2, described cutter structure 4 comprises the handle of a knife 4a that is connected with rotating shaft, the upper fixed cutter body 4b of handle of a knife 4a, and cutter hub 4b bearing spring 4d, blade 4d is connected on the spring 4d, and cutter structure 4 is done the rotating Vortex motion in company with rotating shaft 3.
Such as Fig. 3, described cutter hub 4b comprises the hierarchic structure 4b2 of main body 4b1 and main body 4b1 lower end, and it is some by spring 4d connection blade 4d thereon evenly to arrange on the hierarchic structure 4b2, and the most advanced and sophisticated angle of described blade 4d is 45 °.Retainer is fixed on the rotating disk 5, and the rotation of rotating disk 5 is carried out the five equilibrium revolution by buncher two controls of its underpart, and hole of every processing just turns a five equilibrium.
Because blade 4d is arranged on the hierarchic structure 4b2 of cutter hub 4b main body 4b1 lower end, can adapt to the pocket hole bur of removing difformity, size.
Its blade 4d contacts with the pocket bore edges that retainer need to be removed burr, do stereo-motion according to the size of retainer pocket hole bur and remove burr, in the process of removing burr, cutter hub 4b is connected with spring 4d, the blade 4d that removes burr is connected on the spring 4c, according to the size of deburring, the power of removal is different, and cutter can shrink under the effect of spring 4d automatically.
The present invention removes that retainer pocket hole bur is effective, efficient is high.
