[0027] The following will be combined Figure 1-3 , a manipulator clamp for a bearing inner ring forging according to an embodiment of the present application is described in detail. It should be noted that the following embodiments are only used to explain the present application and do not constitute a limitation on the present application.

[0028] Embodiment 1:

[0029] See also Figure 1-3 As shown, a manipulator clamp for bearing inner ring forgings includes: a mounting base 9, a slider 8, a connecting rod 7 unit, a cylinder 4, a gripper finger 10, an extension rod 5, and a mounting frame 2. The mounting base 9 is provided with three slide grooves penetrating along the thickness direction; the three slide grooves are of equal length, distributed on a concentric circle, and the three slide grooves are distributed at equal intervals. In this way, the sliders 8 arranged in the slide grooves can move simultaneously. The three sliders 8 are correspondingly slidably installed in the slide grooves; the slide grooves are configured as cross slide grooves 12, and the slider 8 has a convex block structure that matches the slide groove. The advantage of such a setting is to improve the stability of the slider 8 running in the slide groove.

[0030] The cylinder 4 is a standard double-acting cylinder 4, which is installed on the flange 1 by screws, and the extension rod 5 is installed on the piston rod of the cylinder 4 and locked with a nut. Then the cylinder 4, the extension rod 5 and the flange 1 are embedded in the mounting frame 2 as a whole. The flange 1 boss and the inner hole clearance of the mounting frame 2 are matched and fixed to the mounting frame 2 by screw connection. There are two windows on the mounting frame 2, one for leaving the air inlet and outlet of the cylinder 4, and the other for adjusting the installation of the extension rod 5.

[0031] The setting of the extension rod 5 can lengthen the piston rod of the cylinder 4, and the control distance can be extended by lengthening the piston rod of the cylinder 4 to avoid the high temperature of the inner ring forging of the bearing.

[0032] The connecting rod 7 unit is configured as follows: it is rotationally connected to each slider 8, and when the connecting rod 7 unit moves in a direction perpendicular to the mounting base 9, it can drive the slider 8 to make corresponding movements in the slide groove; the connecting rod 7 unit includes a movable seat 6 and a plurality of connecting rods 7, one end of the plurality of connecting rods 7 is rotationally connected to the movable seat 6, and the other end of the plurality of connecting rods 7 is rotationally connected to the slider 8, respectively.

[0033] After installation, the extension rod 5 and the mounting frame 2 are guaranteed to be on the same axis. The other end side of the extension rod 5 is inserted into the movable seat 6, and the movable seat 6 can be adjusted to the upper and lower positions by rotating the thread. By adjusting the upper and lower positions of the movable seat 6, the starting position of the slider 8 also moves accordingly, thereby adjusting the position of the gripper finger 10, that is, adjusting the position of the movable seat 6 can adjust the moving range of the gripper finger 10. The mounting base 9 is fixed to the mounting frame 2 through the connecting block 3. The movable seat 6 is connected to the slider 8 through the connecting rod 7 and the pin 11. The gripper finger 10 is mounted on the slider 8 by screws.

[0034] Finally, it is installed as a whole on the end flange 1 of the manipulator. The gripper finger 10 is L-shaped, and the side of the L-shaped gripper finger 10 that is used to contact the inner ring forging of the bearing is provided with a serrated surface with a V-shaped groove. The serrated surface with a V-shaped groove is added to the gripper finger 10 to increase the contact points between the gripper finger 10 and the inner wall of the inner ring forging of the bearing, thereby increasing the friction.

[0035] The flange 1 and the screw fixture are integrally installed on the manipulator, the cylinder 4 is connected to the solenoid valve and ventilated, the solenoid valve is energized, the piston rod of the cylinder 4 extends, driving the extension rod 5 and the movable seat 6 to move downward, and then the three sliders 8 are moved outward in the cross slot 12 of the mounting base 9 through the connecting rod 7, and the three clamping fingers 10 connected below also move outward, that is, the clamping fingers 10 open and clamp the inner ring forging of the bearing. On the contrary, the solenoid valve is de-energized, the piston rod of the cylinder 4 shrinks, driving the extension rod 5 and the movable seat 6 to move upward, and then the three sliders 8 are moved inward in the cross slot 12 of the mounting base 9 through the connecting rod 7, and the three clamping fingers 10 connected below also move inward, that is, the clamping fingers 10 shrink and release the inner ring forging of the bearing.

[0036] The above description is only a preferred embodiment of the present invention and is used to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
