Description

TECHNICAL FIELD

[0001] The present application relates to the field of bearing inner ring processing, in particular to a bearing inner ring hole position processing equipment with automatic feeding and discharging. BACKGROUND

[0002] As shown in the drawings Figure 1 The bearing inner ring 100 is provided with a ball sliding groove 102 at one end of the outer cylindrical surface and a pair of radially open through holes 101 at the other end. When the through holes 101 of the bearing inner ring are processed, the bearing inner ring 100 is fed to the punching device through the track. During this process, the bearing inner ring 100 always maintains an axial vertical state. Since the bearing inner ring 100 is provided with a ball sliding groove 102, the bearing inner ring 100 is placed in a directional manner during drilling. A pair of error detection rods are provided on the existing track to cooperate with the ball sliding groove 102. When the bearing inner ring 100 in the track is in the correct direction, the ball sliding groove 102 is directly opposite the pair of error detection rods, so that the bearing inner ring 100 can smoothly move to the punching device. When the bearing inner ring 100 in the track is in the incorrect direction, the ball sliding groove 102 is misaligned with the pair of error detection rods, and the bearing inner ring 100 is blocked by the pair of error detection rods.

[0003] The above related technology has the following defects: when the bearing inner ring 100 is blocked, manual overturning is required. The operator generally needs to pay attention to multiple devices. When the bearing inner ring 100 of multiple devices is in the incorrect direction, the operator cannot timely overturn the bearing inner ring 100, which affects the feeding of the bearing inner ring 100. In order to avoid the situation that the bearing inner ring 100 is not fed in time due to the blocking of the bearing inner ring 100, the operator needs to pay more attention to this blocking position, which inevitably increases the burden of the operator. In summary, the manual overturning error correction method of manually overturning the bearing inner ring 100 is not conducive to the feeding of the bearing inner ring 100, and greatly increases the labor intensity of the operator.

[0061] The working principle of the automatic loading and unloading bearing inner ring hole machining equipment of this application is as follows:

[0062] As the feeding plate 12 rotates clockwise, the bearing inner rings 100 on the feeding plate 12 sequentially enter between a pair of feeding guide plates 14 and reach the feeding horizontal conveyor belt 17 along the transition seat 15. The feeding horizontal conveyor belt 17 drives the bearing inner rings 100 to move towards the intermediate support device 30. When the bearing inner rings 100 are inverted, a pair of blocking rods 19 block the bearing inner rings 100. Then, the lifting drive plate 28 descends, causing the gripper 80 to grab the inverted bearing inner rings 100. Next, the lifting drive plate 28 rises back to its original position, and then a pair of movable support columns 23 move towards the intermediate support device 30 until the bearing is flipped. The seat 24 is located directly below the gripper 80. The gripper 80 then releases the bearing inner ring 100, which vertically enters the storage groove 240. The support column 23 is then moved away from the intermediate support device 30 and returned to its original position. After multiple gripping operations, the storage groove 240 is filled with inverted bearing inner rings 100. Then, a pair of closing blocks 25 move closer together to seal the opening of the storage groove 240. Next, the rotating seat 24 rotates 180 degrees, so that the opening of the storage groove 240 faces downwards. During this process, the bearing inner rings 100 in the storage groove 240 are flipped. Then, a pair of falling limit electric cylinders drive a pair of falling limit columns. 2521 moves closer to abut against the second bearing inner ring 100 from bottom to top, and then a pair of sealing blocks 25 move away from each other, so that the lowermost bearing inner ring 100 falls vertically onto the loading horizontal conveyor belt 17. Then, a pair of sealing blocks 25 move closer to each other to close the opening of the receiving groove 240. Then, a pair of falling limit electric cylinders drive a pair of falling limit posts 2521 to move away and then move closer to each other, so that the second bearing inner ring 100 from bottom to top is restricted by a pair of falling limit posts 2521. When the pair of sealing blocks 25 move away from each other, the lowermost bearing inner ring 100 falls vertically onto the loading horizontal conveyor belt 17. Based on the above principle, the bearing inner rings 100 in the receiving groove 240 fall sequentially onto the loading horizontal conveyor belt 17; thus, the bearing inner rings do not require manual intervention when flipping, which is beneficial for loading the bearing inner rings; then the bearing transfer device 70 moves the bearing inner rings 100, which are pressed against the end baffle plate 18, to the intermediate support device 30, where the hole machining device performs hole machining on the bearing inner rings 100; then the bearing transfer device 70 moves the machined bearing inner rings 100 to the unloading device 40, where the bearing inner rings 100 are unloaded at an angle; this automatic loading and unloading improves the processing efficiency of the bearing inner rings.

[0063] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
