Abstract
The present invention belogns to an abrasive machining machine of cylinder roller bearing outer race-lip free from burn and crack. Said machining method is implemented on the machine tool, and includes the following steps: firstly, utilizing holding device to hold the bearing outer race, making abrasive wheel be fed into grinding position and plunged into roller path, then starting bearing outer race and abrasive wheel, and utilizing abrasive wheel to grind out defined lip, then drawing out the bearing outer race and abrasive wheel. When it is used for machining, the ratating direction of bearing outer race is identical to that of abrasive wheel, at the same time two cooling liquor pipes can be used for spraying cooling liquor on the upper end of grinding point of external end face of said abrasive wheel.
Description
Affiliated technical field
The invention belongs to the grinding processing method of bearing outer ring rib, what relate generally to is the nothing burn of a kind of cylinder roller bearing outer ring rib and the processing method of crackle.
Background technology
At present, the grinding processing method that is used for cylinder roller bearing outer ring rib, it is to carry out on lathe, utilize spring perch to clamp lasso, emery wheel enters grinding position incision raceway, starts workpiece 2 and emery wheel 1, workpiece is done running counterclockwise with 750 rev/mins speed, same emery wheel (clockwise direction) is done rightabout operation (as shown in Figure 1), utilizes two end faces of emery wheel 1 cylindrical, grinds two ribs respectively.In the grinding rib, utilize a cooling water pipe 3 to lower the temperature (as shown in Figure 2) by natural cooling, this processing method makes spark splash, because emery wheel and workpiece direction of rotation are inconsistent, in action of centrifugal force in addition, impel most of cooling water can not enter grinding area effectively, can't take away the heat energy that is produced of most grindings, do not have the effect that reduces the temperature in the grinding area effectively, clean the abrasive dust weak effect, thereby be easy to generate burn and seminess, because of burn and the percent defective that causes of crackle up to more than 20%.In addition, when emery wheel and workpiece direction of rotation were inconsistent, its frictional force was bigger, and the emery wheel degree that comes off is very fast, made constantly to repair emery wheel in machine process, and non-cutting time is long, and efficient is lower.
Summary of the invention
The objective of the invention is to propose the nothing burn of a kind of cylinder roller bearing outer ring rib and the processing method of crackle, make it eliminate burn and the seminess that causes because of grinding, thereby improve yield rate, reduce production costs.
Purpose of the present invention can adopt following technical scheme to realize: its processing method is to carry out on lathe, at first utilize the clamp clamps lasso, and after making emery wheel enter grinding position incision raceway, start workpiece and emery wheel, after utilizing wheel grinding to go out the rib of regulation, withdraw from workpiece and emery wheel; Add man-hour, the direction of rotation of workpiece is consistent with the emery wheel direction of rotation, sprays cooling fluid with two coolant pipes to the grinding points upper end of emery wheel outer face simultaneously.
In order to make coolant pipe and grinding carriage synchronous operation, two coolant pipes are fixed on the emery wheel axle housing, and shower nozzle is positioned at top, emery wheel outer face.
The present invention does not change the master operation of machining bearing outer ring rib, just adding man-hour, workpiece is consistent with the emery wheel direction of rotation, and raising workpiece rotary speed, spray with the grinding points upper end of two coolant pipes simultaneously in the emery wheel outer face, make the inertia of the cooling water of injection by emery wheel and workpiece, consistent with emery wheel in the space of raceway with the workpiece direction of rotation, run up, water in the whole raceway space is followed both run-in synchronisms and is impacted the preceding emery wheel cylindrical of grinding points and the angle of grinding points, water can be formed one high-velocity flow by force by grinding area by compression separation by force, plays powerful cooling and cleaning performance.Adopt processing method of the present invention when processing work, almost there is not spark, the temperature of workpiece is also more lower slightly than the temperature of cooling water after the completion of processing, this explanation, the cooling fluid that circulates at a high speed in raceway is along the emery wheel of raceway impact high speed rotation, during by lip grinding point, taken away most grinding heats.Simultaneously, workpiece that is rotated again after cooling fluid is by grinding points and emery wheel are thrown a part under action of centrifugal force, abrasive dust also is cleaned thereupon, at this moment, cooling water replenishes in the grinding points upper end again continuously, the current that circulate at a high speed in the raceway can not reduce and heat up always, thereby have eliminated outer ring rib burn and the seminess that causes because of grinding.Processing method of the present invention, through practical operation, the workman is acceptant, and quality can reach technological requirement fully.Because workpiece and the equidirectional operation of emery wheel, make that both frictional force are corresponding to reduce, the emery wheel loss is little, corresponding minimizing non-cutting time.Compare with existing method, overall grinding time decreased, with 80 be example, existing method is with 5-6 emery wheel, this processing method only needs a slice emery wheel to get final product, saved non-cutting time greatly, make the corresponding raising of processing progress, can improve class output about 50%, thereby reach the finished product rate that improves, increase work efficiency the purpose that reduces production costs.

The specific embodiment
In conjunction with the accompanying drawings, embodiments of the invention are as follows:
Shown in Fig. 3,4,5, processing method of the present invention is to carry out on internal grinder, is example with the M250 grinding machine, and its operation is identical with existing processing method.At first utilize spring perch to clamp cylinder roller bearing outer ring 2, make emery wheel 1 enter grinding position, and behind the incision raceway, start outer ring 2 and emery wheel 1, make its rotation, bearing outer ring 2 direction of rotation are consistent with the direction of rotation of emery wheel 1, its workpiece rotary speed is 1450 rev/mins, emery wheel is 2950 rev/mins, be clockwise (as shown in Figure 3), fluffing rib 6 (as shown in Figure 4) and outside rib 7 when (as shown in Figure 5), with two cooling water pipes 3 spraying cooling water on the grinding points of emery wheel outer face, two cooling water pipes 3 are fixed on the grinding wheel spindle shell 5, and with grinding wheel spindle 4 synchronous operations, the shower nozzle of cooling water pipe 3 is positioned at emery wheel outer face top, in grind rib 6 with outside behind the rib 7, withdraw from bearing outer ring 2 and emery wheel 1, the processing that enters next workpiece.
