Description

The processing unit (plant) that is used for the groove milling of bearing ring end face

Technical field

The present invention relates to a kind of mechanical device, more particularly, relate to groove milling and use processing unit (plant).

Background technology

Four row milling train cylinder roller bearings have 6-12 end face oil-way on many cycle surfaces, biserial, four-row tapered roller bearing are wearing and tearing, the sintering that prevents creep and inner ring side, are provided with oil groove in a side of inner ring and the both sides of inner ring packing ring.Domestic for many years when the machining bearing end face groove; The universal knee-and-column milling machines (X6130, X6140) that adopt utilize general chuck machining bearing end face groove more, whenever mill an end face oil-way and need repeat to tighten workpiece-processing end face groove-unclamp-rotational workpieces angle-tighten again workpiece; The processing that moves in circles; Labour intensity big, production efficiency is low, and the five equilibrium of processing is inhomogeneous, product cost is high.

Summary of the invention

To the defective of above existence, the present invention proposes a kind of bearing ring end face milling slot device.Once be installed, can be continuously several end face groove completion of processing of bearing ring.

In order to achieve the above object; A kind of processing unit (plant) that is used for the groove milling of bearing ring end face of the present invention; Comprise vertical setting main shaft 8, be socketed on the discoid equi-index plate 2 that is provided with on horizontally disposed table base 1, the said base 1 on the said main shaft 8, and the chuck 13 that is provided with on the said equi-index plate 2.Wherein, be provided with crossed roller bearing assembly 3 between said base 1 and the equi-index plate 2; Said main shaft is located on the said equi-index plate and in the main shaft outer end and with the nut connected mode main shaft end cap 7 is set, and in the inboard of said end cap 7 and cannelure that said equi-index plate end face contacts, is provided with thrust bearing 14.

A kind of bearing ring end face milling slot device is through alignment pin (part 4), and fixedly equal portions dish (part 2) makes it fixing clockwise, and against rotating clockwise, crossed roller bearing assembly (part 3) connects the axial and tilting moment of control equal portions dish.It is characterized in that, once be installed, continuously a plurality of grooves on the machining bearing end face

The invention discloses bearing ring end face milling slot device; This device mainly is suitable for the processing of milling train with the inner ring end face groove of inner ring, outer ring and the taper roll bearing of four-row cylindrical roller; Once tighten; Can process a plurality of end face grooves on the end face simultaneously, be mainly used in industries such as bearing machining.The device that adopts can reduce labor intensity, and improves production efficiency simple, practical characteristics.The beneficial effect of the utility model is: bearing ring end face milling slot device is simple in structure, and manual labor alleviates greatly, enhances productivity more than 1 times, has reduced production cost.

The specific embodiment

The present invention as shown in Figure 1 is used for the processing unit (plant) of bearing ring end face groove milling; Comprise vertical setting main shaft 8, be socketed on the discoid equi-index plate 2 that is provided with on horizontally disposed table base 1, the said base 1 on the said main shaft 8, and the chuck 13 that is provided with on the said equi-index plate 2.Shown in Fig. 5-7, the bottom surface of equi-index plate 2 is divided into the keyway of 24 five equilibriums on circumference, can process the end face groove (24,12,8,6,4,3 equal portions) of different five equilibriums.

Among the figure,, make it fixing clockwise, contraryly can rotate clockwise through the fixing equi-index plate 2 of alignment pin 4.The structure of alignment pin is shown in Fig. 7-8.The guide pin bushing structure of alignment pin is shown in figure 10, and the bottom that in Fig. 1, is positioned at alignment pin in the guide pin bushing 5 also is provided with spring 6.

In addition, illustrated in figures 1 and 2, be provided with crossed roller bearing assembly 3 between base 1 and the equi-index plate 2.Concrete structure is shown in Fig. 3-4, and table base 1 connects crossed roller bearing assembly 3 through soket head cap screw 15, and crossed roller bearing assembly 3 also connects equi-index plate through soket head cap screw 16.And equi-index plate connects chuck 13 through soket head cap screw.Wherein, crossed roller bearing assembly 3 connects the axial and tilting moment of control equi-index plate.

Among Fig. 1, main shaft is located on the equi-index plate 2 and in the main shaft outer end and with the nut connected mode main shaft end cap 7 is set, and in the inboard of said end cap 7 and cannelure that said equi-index plate end face contacts, is provided with thrust bearing 14.Among Fig. 1, label 12 is the outer ring of four-line column roller bearing, and label 11 is for needing the bearing face groove of processing.
