Abstract
A device for processing an oil groove in a rolling manner comprises a bracket, two rolling wheels, a positioning steel ball and a positioning seat, wherein the two rolling wheels are oppositely and perpendicularly arranged on two sides in the axial direction of a workpiece; the positioning seat is arranged at the other end, far away from the two rolling wheels, of the workpiece in the extending direction of the workpiece; a positioning hole is formed in the end, facing to the workpiece, of the positioning seat; the positioning steel ball is pressed into and matched with the positioning hole in a press-fit manner and is in interference fit with the positioning hole. According to the utility model, the spherical positioning mode is adopted, and the workpiece is positioned by the positioning steel ball in the axial direction, so that the oil groove formed by rolling is smooth and free of flashes and burrs, good in quality and high in processing efficiency. In addition, the end surface of the workpiece and the spherical surface of the positioning steel ball are in point-to-surface contact, and compared with the surface-to-surface contact manner, the friction resistance is reduced even to be zero, so that disorder caused by the reason that rotation of the workpiece lags behind rotation of the rolling wheels due to interference of a big friction force is avoided.
Description
Technical field
The utility model relates to a kind of device that adopts rolling method processing oil groove on axial workpiece.
Background technology
Oil storage and lubricated many (8) helical oil grooves of processing that need are considered in differential spider pinion shaft two ends, common process method is for adopting many helical oil grooves of Vehicle Processing, first will be clamping workpiece on fixture, process Article 1 oil groove by lathe, and then by the artificial calibration of adjusting, reprocessing Article 2 oil groove, oil groove working (machining) efficiency that this method is processed to form is extremely low, of poor quality, burr is many, also need following process production cost high.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide the device of the high and employing rolling method processing oil groove that friction is less of a kind of efficiency.
For solving above-mentioned purpose, the technical scheme that the utility model adopts is as follows:
The device of rolling method processing oil groove comprises bracket, two rolling wheels, locking ball and positioning seats; Workpiece support is positioned on bracket, and relatively and be vertically installed in the both sides of workpiece axial direction, positioning seat is arranged at the other end of workpiece away from two rolling wheels along workpiece bearing of trend for two rolling wheels; Positioning seat is provided with locating hole towards one end of workpiece; Locking ball be press-fit in locating hole by the mode being press-fitted and with locating hole interference fit.
Locking ball contacts with workpiece end face with a way of contact.
Compared to existing technology, the beneficial effects of the utility model are:
Adopt rolling method processing oil groove, adopt location at spherical surface mode, locking ball positions workpiece vertically, the smooth non-trimming burr of oil groove of roll forming, and quality is good, and working (machining) efficiency improves 100 times of left and right.In addition, between the end face of workpiece and locking ball sphere, be that point contacts with face, the face of comparing and its frictional resistance of the face way of contact diminish and even trend towards zero, avoid the rotation that will lag behind rolling wheel because of the rotation of the large interference workpiece of frictional force to produce random groove.
Brief description of the drawings
Fig. 1 is the lateral plan of oil groove machining device in the utility model;
Fig. 2 is oil groove machining device top view shown in Fig. 1;
Fig. 3 is oil groove machining device partial enlarged drawing shown in Fig. 2;
Wherein: 10, bracket; 20, rolling wheel; 30, locking ball; 40, positioning seat; 41, locating hole; 99, workpiece.
Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
As shown in Figure 1, Figure 2 and shown in Fig. 3, be the device that the utility model adopts rolling method processing oil groove, it is applied in screw-thread rolling machine (not shown).Wherein, the concrete structure of screw-thread rolling machine does not repeat them here.
Oil groove machining device comprises bracket 10, two rolling wheels 20, locking ball 30 and positioning seats 40.Workpiece 99 supports and is positioned on bracket 10.Two rolling wheels 20 are along the both sides that are arranged at workpiece 99 perpendicular to workpiece 99 axial directions and need to process one end.Positioning seat 40 is arranged at the other end of workpiece 99 away from two rolling wheels 20 along workpiece 99 bearing of trends.Positioning seat 40 is provided with locating hole 41 towards the axle center place of workpiece 99.Locking ball 30 adopts interference fit with locating hole 41, and it press fit in locating hole 41 by the mode being press-fitted.For example, the locating hole that is φ 10+0.005 positioning seat when the diameter of steel ball is exactly diameter phi 10-0.005.In the present embodiment, positioning seat 40 is movably, and can adjust relevant position according to the Working position of workpiece, plays the effect of location.
In when work, the surface that two rolling wheels 20 are connected to workpiece to be processed 99 both sides in the effect of driving element (not shown) is rotated and feeding.Now, workpiece 99 rotates under the drive of two rolling wheels 20, and its one end that need process is held between two rolling wheels 20, and the other end is close to the location sphere that is connected to locking ball 30.Because rolling is helical oil groove in the oil groove on workpiece 99 surfaces, therefore rolling wheel 20 workpiece 99 in the time rolling oil groove will be subject to irregular processing external force.In the utility model, adopt location at spherical surface mode, locking ball 30 can position workpiece 99, the smooth non-trimming burr of oil groove of roll forming, and quality is good, and working (machining) efficiency is high.In addition, between the end face of workpiece 99 and locking ball 30 spheres, be that point contacts with face, compare existing and diminish and even trend towards zero with its frictional resistance of the face way of contact, avoid the rotation that will lag behind rolling wheel because of the rotation of the large interference workpiece of frictional force to produce random groove.
The utility model adopts the method for above-mentioned oil groove machining device rotary rolling mill oil groove: workpiece 99 is positioned on bracket 10; Two rolling wheels 20 are along the both sides that are held on workpiece 99 perpendicular to workpiece 99 axial directions and need to process one end; Adopt locking ball 30 to be axially connected to the other end of workpiece 99 away from two rolling wheels 20 along workpiece 99; Starting driving element makes two rolling wheels 20 form oil groove with respect to workpiece 99 rotations and feeding with rolling.
To one skilled in the art, can be according to technical scheme described above and design, make other various corresponding changes and deformation, and within these all changes and deformation all should belong to the protection domain of the utility model claim.
