Background art:

spline shaft parts such as a hollow transmission shaft, a solid transmission shaft and the like are indispensable components in the integral automobile, the quality of splines of the spline shaft parts directly influences the normal operation of a power system of an automobile, the reliability of spline connection is very important, annular grooves are machined in the spline positions of part of the transmission shaft for clamping snap rings, and the stability of clamping the snap rings directly influences the stability, safety and service life of the normal running of the whole automobile. In the prior art, the spline shaft is firstly provided with the spline and then turned with the ring groove, and burrs are generated at positions such as the thickness of the spline teeth. If the burr is not removed, there is a risk that the snap ring will escape. Before the device is adopted, automobile spline shaft production enterprises mainly adopt a spline ring gauge to remove the burrs of a spline ring groove or manually remove the burrs by using a deburring roller at the present stage, and although the cost and the efficiency of the latter method are greatly improved compared with the former method, the contradiction between the continuously increased yield and the deburring efficiency is increasingly remarkable. Therefore, the spline deburring synchronizing device is developed, the grooving process and the deburring process are combined into one process, the production efficiency of products can be greatly improved, the processing strength is reduced, and the processing cost is reduced.

The utility model has the following contents:

in order to solve the technical problem, the utility model provides a deburring device.

Furthermore, the axis of the guide hole and the transverse tangent plane of the base are in a state of less than 1 degrees to less than 45 degrees, and the preferable range is less than 13 degrees.

Furthermore, the guide hole is a stepped through hole, a pin hole is formed in the hole wall, and a fixing pin is arranged in the pin hole.

Furthermore, a threaded hole is formed in the hole opening of the guide hole and used for fixing the pin.

Furthermore, the upper end of the support rod is small, the lower end of the support rod is large, and N pairs of springs are sleeved in the middle of the support rod.

Furthermore, the support rod is nested in the guide hole and matched with the fixed pin in the hole.

Furthermore, the outer circle of the supporting rod is provided with a straight groove parallel to the deburring tube wheel so as to ensure the correct meshing of the deburring roller wheel and the spline.

Furthermore, the roller moves along with the feeding direction of the turning tool, when the roller is contacted with the surface of a workpiece, the roller is extruded, the roller contracts along the direction of the supporting rod, and the spring is compressed.

Furthermore, the roller is meshed along the spline grooves turned by the turning tool to extrude and remove burrs, and then the roller is far away from the workpiece along with the tool withdrawal, so that the spline groove turning and deburring processes are completed.

The application provides a burring device includes: lathe tool, gasket, dress blade holder, base, fastening screw and burring device, its characterized in that: the tool holder is matched with a tool turret of a machine tool in an installing way, a threaded hole and a positioning groove are formed in the top of the tool holder, and the positioning groove is used for installing a base; the base is provided with a guide hole for mounting a deburring device; the deburring device comprises a support rod, a fastening nut, a spring, a positioning shaft and a roller, wherein the support rod is provided with a roller inner sleeve bearing and is fixed at the tail end of the support rod, and the positioning shaft is fixed by a fastening screw; the method has the following technical effects:

the two working procedures of turning the groove and deburring are connected in parallel, and the turning of the groove and the deburring are carried out simultaneously, so that compared with the traditional deburring mode, the processing time is obviously shortened, and the labor intensity of workers is greatly reduced; the service life of the deburring roller is greatly prolonged compared with that of a ring gauge; when the deburring effect is weakened, the whole mechanism can start to work again only by replacing the roller. .
