[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0033] See also Figure 1 , a bearing grabbing device shown in the figure comprises: a lateral moving mechanism 100, a first double-headed cylinder 200 and a bearing grabbing mechanism 300. The first double-headed cylinder 200 is mounted on the lateral moving mechanism 100 and driven by the lateral moving mechanism 100 to move.

[0034] The bearing grabbing mechanism 300 is connected to the piston rod 210 in the first double-headed cylinder 200, and is driven to move up and down by the first double-headed cylinder 200. A plurality of bearing grabbing hands 414 are arranged in the bearing grabbing mechanism 300. In this specific embodiment, there are a total of 12 bearing grabbing hands 414, and these 12 bearing grabbing hands can grab and release six bearings 500 at a time; wherein every two bearing grabbing hands 414 grab one bearing 500.

[0035] See also Figure 2 The lateral movement mechanism 100 shown in the figure includes a frame 170, and a cavity 171 is arranged in the frame 170. The ball screw nut mechanism and the support rod 130 in the lateral movement mechanism 100 are installed in the cavity 171 of the frame 170, the two ends of the screw 120 in the ball screw nut mechanism are axially arranged on the frame 170, and the two ends of the support rod 130 are fixed on the frame 170.

[0036] The moving frame 150 in the transverse moving mechanism 100 is fixed on the nut 140 in the ball screw nut mechanism, so that the ball screw nut mechanism can drive the moving frame 150 to move in the cavity 171. The moving frame 150 slides with the support rod 130, and the support rod 130 guides the moving frame 150.

[0037] A motor 180 is installed at one end of the frame 150 , and the motor 180 is drivingly connected to one end of the screw 120 in the ball screw nut mechanism to drive the screw 120 to rotate.

[0038] In order to prevent dust from entering the cavity 171 , a baffle 160 is installed on the frame 120 using screws 110 .

[0039] The first double-headed cylinder 200 is mounted on the frame 170 through a cylinder bracket, and the lower end of the piston rod 210 in the first double-headed cylinder 200 is connected to the middle position of the support plate 310 in the bearing grabbing mechanism 300 through the upper and lower nuts 230. Four support bolts 320 are respectively installed on the four corners of the support plate 310.

[0040] See also Figures 3 to 5 The bearing grabbing mechanism shown in the figure also includes a support platform 418, and a threaded hole 411 is respectively opened at the four corners of the support platform 418. By screwing four support bolts 320 into the four threaded holes 411, the support platform 418 can be connected to the support plate 310 through the four support bolts and located below the support plate 310.

[0041] Twelve grabbing holes 423 are arranged in an array on the support platform 418. The twelve grabbing holes 423 are divided into two rows, each row has six grabbing holes 423, and each row has two grabbing holes 423. In addition, a longitudinal slide groove 424 and 12 transverse slide grooves 422 are arranged on the upper surface of the support platform 418 along the length direction of the support platform 418. The 12 transverse slide grooves 422 are arranged at intervals on the upper surface of the support platform 418 along the length direction of the support platform 418 and cross the longitudinal slide grooves 424. A transverse slide groove 422 is arranged on both sides of each row of grabbing holes 423 along the length direction of the support platform 418.

[0042] A second double-headed cylinder 421 is installed in the middle of the support platform 418. A long piston rod 420 is hinged at each end of the piston shaft of the second double-headed cylinder 421. The second double-headed cylinder 421 drives the two long piston rods 420 to perform linear motion along the length direction of the support platform 418. The two long piston rods 420 are configured in the longitudinal slide groove 424 in a sliding manner.

[0043] The bearing grabbing mechanism of this specific embodiment further includes 12 hand bars 416 , which are divided into six groups, each group having two hand bars 416 . The six groups of hand bars 416 are arranged at intervals along the length direction of the support platform 418 .

[0044] The inner ends of the two hand levers 416 in each group are hinged to each other and to the long piston rod 420, so that the long piston rod 420 can synchronously drive the six groups of hand levers 416 to move synchronously; the outer ends of the two hand levers 416 in each group are respectively hinged to the middle position of a hollow rod 414, and each hollow rod 414 is arranged parallel to the long piston rod 420. The movement of the two hand levers 416 in each group drives the two hollow rods 414 to move back and forth along the width direction of the support platform 418.

[0045] A bearing grabber 414 is hingedly connected to the middle of each hollow rod 414 through a cylindrical bearing 417. Each bearing grabber 414 passes through the grabbing hole 423 and extends to the bottom of the support platform 418. A grabber 416 is provided at the lower end of the bearing grabber 414. The cylindrical bearing 417 can be used to conveniently adjust the direction of the grabber 416 at the lower end of the bearing grabber 414.

[0046] A movable slider 412 is hinged at both ends of each hollow rod 414 , and the movable slider 412 is configured in a corresponding transverse sliding groove 422 in a sliding manner.

[0047] The working principle of the bearing grabbing device of the present invention is as follows:

[0048] When the bearing 500 reaches the fixed position of the stacking table 600, the transverse moving mechanism 100 moves to the fixed bearing stacking table 600, and the piston rod 210 of the first double-headed cylinder 200 moves downward to make the bearing grabbing mechanism 300 move downward together. Then, the 12 bearing grabbing hands 414 contact the bearing stacking table 600, and the system issues a command to move the second double-headed cylinder 421. The second double-headed cylinder 421 drives the two long piston rods 420 to move forward, so that the 6 sets of hand rods 415 open, and the grabbing hands 416 at the lower ends of the 12 bearing grabbing hands 414 contact the inner ring end face of the bearing 500 and shovel up the bearing 600. Then, the system issues a command to lift the piston rod 210 of the first double-headed cylinder 200, and then the system issues a command to make the transverse moving mechanism 100 move laterally to the next workstation.

[0049] When the lateral moving mechanism moves, the system issues a command to the motor 180 to rotate and drive the screw 120 in the ball screw nut mechanism to rotate, and the screw 120 in the ball screw nut mechanism drives the nut 140 to move. Since the nut 140 and the moving frame 150 are fixed, the nut 140 and the moving frame 150 can move smoothly left and right with the rotation of the motor 180. The baffle 160 and the support rod 130 are used to fix the moving frame 150, and the baffle 160 can also block contaminants from entering the screw 120 of the ball screw nut mechanism to avoid contaminating the smooth movement of the screw 120.

[0050] The system issues a command to cause the piston rod 210 of the first double-headed cylinder 200 to move up and down, driving the support plate 310 and the support rod 320 in the bearing grabbing mechanism to move.

[0051] The system sends out a command to make the second double-headed cylinder 421 move left and right, thereby driving the 6 sets of hand levers 415 to open their angles, so that the movable slider 412 slides in the transverse groove 422 and the hollow rod 413 moves to both sides, so that the bearing grabbing hand 414 expands outward in the grabbing hole 423, thereby shoveling the inner ring of the bearing 500 and leaving the bearing stacking table 600.

[0052] The bearing grabbing device of the present invention can grab a plurality of bearings 500 at a time and stably place them in other workstations, thus filling the gap of how to grab the bearings 500 after they are finished.

[0053] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
