Problems solved by technology

However, the outer end of the emery wheel is generally in a "U" shape, and the repair of the outer end of the emery wheel and the emery wheel can only repair the outermost edge of the emery wheel, and the overall "U" shape of the outer end of the emery wheel cannot be obtained. Repair, therefore, the aforementioned grinder is less effective at repairing

Embodiment 1

[0040] A grinding machine for grinding the inner ring of a bearing, such as figure 1, including a bed body 1, the bed body 1 is provided with a fixed seat 13 and a lead screw adjustment mechanism 14, and a clamp 2 is installed on the fixed seat. A grinding seat 15 is installed on the leading screw adjustment mechanism 14, and the grinding seat 15 is connected with an emery wheel 3 towards one side of the fixed seat, and a drive motor 31 for driving the emery wheel 3 to rotate is installed on the other side. Bearing is installed on fixture 2, and drive motor 31 drives emery wheel 3 to rotate, and screw adjustment mechanism 14 drives grinding seat 15 to feed, and emery wheel 3 stretches in the bearing inner ring and grinds bearing inner ring.

[0041] Such as figure 2 , The fixture 2 includes a support plate 21 fixed on the fixed seat, and the support plate 21 is provided with a grinding port 211 for placing the bearing. A placement channel 24 is fixed on the support plate 21...

Embodiment 2

[0058] The difference between the second embodiment and the first embodiment is that the connection mode between the support base 4 and the bed body 1 is different: as Image 6 , a vertical guide rail 12 is installed on the bed body 1, and the support seat 4 is slidably connected in the guide rail 12. A lifting motor 17 and a lifting screw 18 are installed in the guide rail 12. The lifting motor 17 drives the lifting screw 18 to rotate, and the lifting screw 18 drives support seat 4 to slide up and down. When the support seat 4 is grinding the emery wheel 3, the support seat 4 moves down, and after the grinding finishes, the support seat 4 rises and resets.

Embodiment 3

[0060] The difference between the third embodiment and the first embodiment is that the structure of the driving mechanism is different: as Figure 7 , the output shaft 45 of the repair motor 44 is perpendicular to the repair shaft 41 , and the drive mechanism includes a drive disc 53 , a drive link 54 , a drive rack 55 and a drive gear 56 .

[0061] Such as Figure 7 , the output shaft 45 of the repair motor 44 is coaxially fixedly connected with the drive disc 53, and the drive disc 53 is rotatably connected to the support base 4, and the support base 4 is provided with a horizontal slide groove 46 communicating with the rotation hole 48, driving The rack 55 is slidably connected in the sliding groove 46 . The drive link 54 is connected between the drive rack 55 and the drive disc 53 , one end of the drive link 54 is hinged to the drive disc 53 , and the other end is hinged to the drive rack 55 . The driving disc 53 rotates, and the driving connecting rod 54 drives the dri...

Abstract

The invention relates to the technical field of grinding machines, and discloses a grinding machine for grinding a bearing inner ring. The grinding machine for grinding the bearing inner ring comprises a machine body, wherein the machine body is provided with a clamping tool, a grinding wheel and a repairing device; the repairing device comprises a supporting seat; the supporting seat is movably connected to one side, at the grinding wheel, of the machine body; a repairing shaft is rotatably connected to the inside of the supporting seat; a repairing disc is fixedly arranged at the end, towardthe grinding wheel, of the repairing shaft; a diamond repairing pen matching with the grinding wheel is arranged at the edge of the repairing disc; and the rotating radian of the diamond repairing pen is the same as of the edge of the grinding wheel. Through the arrangement of the repairing disc and the repairing shaft, the diamond repairing pen can rotate to fit a U-shaped outer ring of the grinding wheel, so that the face of the diamond repairing pen is contact with the face of the grinding wheel, the grinding area is large, and the grinding effect is good.

Description

technical field [0001] The invention relates to the technical field of grinding machines, in particular to a grinding machine for grinding inner rings of bearings. Background technique [0002] Bearing is an important component in contemporary mechanical equipment, and its main function is to support the mechanical rotating body. In the prior art, a grinding machine is usually used to grind the outer surface of the inner ring of the bearing. [0003] The Chinese patent with the publication number CN108000258A discloses a multi-directional displacement adjustable bearing inner ring grinder, including a grinding wheel system, a workpiece system, a chip removal and cooling system, a control system and a grinding wheel self-dressing system, which can process and shape the shape of the grinding wheel . The grinding wheel self-dressing system includes a dressing wheel seat driving mechanism and a dressing wheel driving mechanism; a dressing wheel seat driving mechanism includes a...
