DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Embodiment 1

[0018] Please refer to Figure 1 and Figure 2 , a hydraulic picking and placing manipulator, including a mounting table 1. The top of the mounting table 1 is detachably connected with a hydraulic cylinder 2. Specifically, the lower end of the hydraulic cylinder 2 is connected with a first flange 14 and is connected to the mounting table 1 through the first flange 14. The upper end of the hydraulic cylinder 2 is connected with a second flange 15, and the hydraulic cylinder can be installed at the required position through the second flange 15. The mounting table 1 is rotatably connected with a rotating shaft 4 through a rotary bearing 3. Both ends of the rotating shaft 4 penetrate out of the mounting table 1 respectively. One end of the rotating shaft 4 is detachably connected with a mounting plate 5. Clamping mechanisms are installed on both sides of the mounting plate 5. The other end of the rotating shaft 4 is detachably connected with a weight block 6. A driving mechanism for driving the rotating shaft 4 to rotate is provided on the mounting table 1.

[0019] The clamping mechanism includes a two-way cylinder 7 connected to the mounting plate 5, a clamping plate 8 connected to the telescopic end of the two-way cylinder and in a Z shape, anti-slip blocks 9 mounted on the opposite faces of the two clamping plates, and guide rails 10 connected to the mounting plate and located at both ends of the two-way cylinder. The lower end of the clamping plate 8 is slidably connected to the guide rail 10. Controlling the contraction of the two-way cylinder 7 drives the two clamping plates to move relative to each other, thereby clamping the article. The two anti-slip blocks can be made of rubber, and the opposite faces of the two anti-slip blocks are provided with corrugations, which on the one hand prevent the article from being damaged, and on the other hand increase the friction force and the clamping force. Moreover, both the guide rail and the chute at the bottom of the clamping plate are in an I shape, so as to prevent the clamping plate from falling off the guide rail.

[0020] The driving mechanism includes a motor 11 installed in the mounting table, a transmission shaft connected to the motor through a coupling, a main gear 12 connected to the transmission shaft, and a secondary gear 13 connected to the rotating shaft. The main gear 12 meshes with the secondary gear 13. There is an installation cavity in the mounting table, and the motor is installed in the installation cavity through bolts. Starting the motor drives the transmission shaft to rotate, and thus through the cooperation of the main gear and the secondary gear, drives the rotating shaft to rotate, thereby driving the mounting plate and the clamping mechanism thereon to rotate.

[0021] The working principle of this embodiment is as follows: The hydraulic cylinder 2 is installed at the required position through the second flange 15. Control the hydraulic cylinder 2 to extend, drive the mounting table 1 to descend, then control the contraction of the two-way cylinder 7 on one side, drive the two clamping plates 8 to move relative to each other, thereby clamping the article. Then start the motor 11, drive the transmission shaft to rotate, and thus through the cooperation of the main gear and the secondary gear, drive the rotating shaft 4 to rotate, so that the mounting plate rotates 180 degrees. Then control the contraction of the two-way cylinder 7 on the other side, thereby grasping the next article. That is, two articles can be grasped within one round-trip stroke of the hydraulic cylinder, saving time and improving the grasping efficiency.

[0022] Embodiment 2

[0023] The difference between this embodiment and Embodiment 1 is that through holes are provided at both ends of the rotating shaft 4, a first sleeve 16 is connected to one side of the weight block 6, a second screw hole is provided on the first sleeve 16, and the first sleeve 16 is fixed to the rotating shaft 4 through bolts. A second sleeve 17 is connected to one side of the mounting plate 5, a third screw hole is provided on the second sleeve 17, and the second sleeve 17 is fixed to the rotating shaft 4 through bolts.

[0024] The weight block 6 can keep both sides of the mounting table 1 balanced. Moreover, according to needs, the weight block 6 can be replaced with a mounting plate and a clamping mechanism, so that clamping mechanisms are provided on both sides of the mounting table, and multiple articles can be grasped simultaneously, further improving the grasping efficiency.
