Abstract
The utility model relates to a rolling device of the bearing sections of the axis class components. The utility model comprises an emale cone sleeve, a hollow shaft, and a locating lever and a plurality of rollers arranged in the hollow shaft. The groove hole section of the hollow shaft is arranged in the emale cone sleeve, the rollers are installed in the corresponding groove hole of the hollow shaft. When the emale cone sleeve rotating in high speed, the rollers are driven, and the work piece is pushed and rolled. The work piece is contacted by the locating lever, the rollers move outward, and the work piece is relaxed and the rolling is stopped. The utility model has the advantages that the design is novel; matched with the rolling equipment, the bearing section of the thin and long axis class work piece can be chosen and rolled, the disease of the whole rolling on the traditional equipment is avoided, and the axis class components processing precision and processing efficiency are greatly enhanced.
Description
The utility model relates to rolling device, specifically is a kind of rolling device of axial workpiece bearing section.
At present, the processing of axial workpiece needs operations such as corase grind, middle mill, correct grinding, grinding and polishing usually, and operation is many, needs repeatedly location, and time-consuming, difficulty reaches quality requirement.Chinese patent rod member surface extra accuracy rolling device (91200173.9) adopts the technology to the roll extrusion of shaft-like workpiece total length, and the machining accuracy of workpiece is increased.It adopts the total length roll extrusion, and axle easily produces flexural deformation, and the processed finished products rate for slender axles (as ￠ 6 * 150mm etc.) is low especially.The precision of axle is low, and vibration shortens the service life of product greatly greatly in high speed rotating.
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, a kind of rolling device of axial workpiece bearing section is provided, this device and the supporting use of roll unit can be realized the local roll extrusion of axial workpiece bearing section has been improved Machining of Shaft-type Parts precision and working (machining) efficiency.
The rolling device of axial workpiece bearing section of the present utility model, comprise: taper hole cover (2), hollow shaft (4), be arranged at backstay (5) and some rollers (3) in the hollow shaft (4), the groove hole section of hollow shaft (4) is provided with some slotted eyes, a roller (3) is installed in each slotted eye, the groove hole section of hollow shaft (4) and corresponding roller place in the taper hole cover (2), when taper hole cover high speed rotating, roller by rotation inwardly advances workpiece automatically, roll extrusion, workpiece touches backstay, roller outwards moves and loosens workpiece, hollow shaft is outwards promoted, can take out workpiece easily, the tumbling length of workpiece is determined by backstay length.
The utility model technical conceive novelty, designs simplification, this device and the supporting use of roll unit can be selected rolling and processing to thin and long shafts workpiece bearing section, avoided the disadvantage of legacy equipment bearing roll extrusion, Machining of Shaft-type Parts precision and working (machining) efficiency are improved greatly.
Axial workpiece by rolling and processing after, the surface to be machined roughness reduces, hardness increases, abrasion resistance significantly improves, especially the effect to the stainless steel shaft roll extrusion is more obvious, and the holoaxial linearity changes below 0.01mm after the local roll extrusion, and can increase more than the twice service life.
Below in conjunction with the embodiment accompanying drawing the utility model is further specified.
Fig. 1 is a structure chart of the present utility model;
Fig. 2 is the side view of Fig. 1;
As shown in Figure 1, 2, the part of this rolling device is: taper hole cover (2), hollow shaft (4), be arranged at backstay (5) and some rollers (3) in the hollow shaft (4).The groove hole section of hollow shaft (4) is provided with 3～7 slotted eyes, and a roller (3) is installed in each slotted eye.The antarafacial angle of the slotted eye center line of hollow shaft (4) groove hole section and the axis of hollow shaft (4) is 0.5～1.5 degree, and exemplary embodiments can be about 1 degree.The groove hole section of hollow shaft (4) and corresponding roller place in the taper hole cover (2), and roller contacts with the endoporus conical surface of taper hole cover (2).The endoporus conical surface of taper hole cover (2) and the angle of cone central axis are 1～5 degree.The roll extrusion length of workpiece is adjusted by backstay (5), when roll extrusion length is long, and the corresponding increase of the length of backstay.
During use, the taper hole cover (2) of device is loaded in the overcoat of equipment, be sleeved on outward with rolling bearing that body links to each other in, put outward belt pulley be housed, by motor drives.Hollow shaft (4) links to each other with body through feather key, does not rotate, and has positioning action, again can be it is extrapolated by control stick, make things convenient for the taking-up of workpiece.When taper hole cover (2) high speed rotating, drive some rollers (3) rotation, because the center line of roller and hollow shaft axis have the antarafacial angle of 1 degree, roller (3) is with workpiece (1) inwardly propelling, roll extrusion automatically, and workpiece (1) touches backstay (5), and roller (3) outwards moves, because the outer imperial palace of the internal taper hole of taper sheath is little, roller (3) loosens workpiece (1), by control stick hollow shaft (4) is outwards promoted, and can take out workpiece (1) easily.
Critical surfaces through the roll extrusion of this device is carefully sweet, and hardness increases, and improved more than the twice service life of workpiece.Because workpiece is adopted local roll extrusion, so the variation of the linearity of whole work-piece is very little, general monarch is below 0.01mm.
Claims (1)
1, a kind of rolling device of axial workpiece bearing section, it is characterized in that comprising: taper hole cover (2), hollow shaft (4), be arranged at backstay (5) and some rollers (3) in the hollow shaft (4), the groove hole section of hollow shaft (4) is provided with some slotted eyes, a roller (3) is installed in each slotted eye, the groove hole section of hollow shaft (4) and corresponding roller place in the taper hole cover (2), when taper hole cover high speed rotating, drive the roller rotation with workpiece inwardly propelling, roll extrusion automatically, workpiece touches outside the moving of backstay roller and loosens workpiece.
