Description

Technical Field

[0001] The utility model relates to an extraction device of a power-assisted manipulator, belonging to the field of mechanical extraction equipment. Background Art

[0002] The extraction device of a power-assisted manipulator is a system that can enhance the grasping and operating capabilities of a manipulator and is widely used in industrial automation, robotics, the medical field, etc. This device usually combines the movement characteristics of a robotic arm and uses auxiliary mechanisms to improve its functions and efficiency. Compared with traditional manual operations, a power-assisted manipulator can quickly and stably complete extraction tasks.

[0003] In the prior art, the clamping groove between the clamping fixtures inside the extraction device is formed by the closing of two fixtures, and a gap is thus generated between the two fixtures. During the extraction process of materials, the gravity of the materials easily spreads the gap between the fixtures, resulting in the phenomenon that the extracted materials slip out from the gap between the fixtures, reducing the extraction stability of the power-assisted manipulator.

[0004] In summary, the utility model provides an extraction device of a power-assisted manipulator to solve the above problems. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an extraction device of a power-assisted manipulator to solve the problem that the gap between the fixtures is easily spread by the gravity generated by the weight of the extracted materials, resulting in the slippage of the extracted materials and reducing the extraction stability of the power-assisted manipulator as mentioned in the above background art.

[0006] To achieve the above purpose, the utility model is realized through the following technical solutions: an extraction device of a power-assisted manipulator, including a mounting base, two connecting seats are fixedly connected to both sides of the mounting base, an installation shaft is rotatably connected between the opposite sides of every two front and rear juxtaposed connecting seats, a right clamping plate is sleeved on the shaft surface of one installation shaft, a left clamping plate is sleeved on the shaft surface of the other installation shaft, comb teeth are arranged at the bottoms of the right clamping plate and the left clamping plate, the tops of the left clamping plate and the right clamping plate extend upward, and a hydraulic transmission component is fixedly connected between the opposite sides of the left clamping plate and the right clamping plate and directly above the mounting base.

[0007] Furthermore, the comb teeth at the bottoms of the left clamping plate and the right clamping plate are meshed with each other, and both the left clamping plate and the right clamping plate are arc-shaped.

[0008] Furthermore, the number of teeth of the comb teeth at the bottom of the left clamping plate is three, and the number of teeth of the comb teeth at the bottom of the right clamping plate is two.

[0009] Further, a threaded hole is formed between the front and back of the mounting base, and the connecting seat is in an arc-bent shape.

[0010] Further, the relative sides of the right clamping plate and the left clamping plate form a circular clamping groove, and the separated ends of the two groups of comb teeth are both in an oblique cutting sharp angle shape.

[0011] Further, one of the mounting shafts is fixedly connected to the right clamping plate, and the other mounting shaft is fixedly connected to the left clamping plate.

[0012] Further, the hydraulic transmission assembly includes four transmission seats. Two transmission seats are respectively fixedly connected to both sides of the top of one side of the right clamping plate, and the other two transmission seats are respectively fixedly connected to both sides of the top of one side of the left clamping plate. A connecting shaft is rotatably connected between the relative sides of every two front and rear juxtaposed transmission seats. Fixed seats are sleeved on the shaft surfaces of the two connecting shafts. A bidirectional hydraulic cylinder is fixedly connected between the relative sides of the two fixed seats, and the connecting shaft is fixedly connected to the fixed seat.

[0013] Advantages of the present utility model:

[0014] After the right clamping plate and the left clamping plate are spliced by driving of the hydraulic transmission assembly, the comb teeth at the bottoms of the right clamping plate and the left clamping plate are engaged with each other, so that the extracted material will not slip off from the splicing gap between the right clamping plate and the left clamping plate due to gravity, effectively improving the extraction stability of the assisting manipulator.

[0015] The comb teeth with oblique cutting sharp angle shapes at the bottoms of the right clamping plate and the left clamping plate are convenient for hooking the material to be extracted faster, effectively improving the material extraction and transportation efficiency.

The beveled sharp corner-shaped comb teeth 6 at the bottoms of the right clamping plate 4 and the left clamping plate 5 facilitate hooking the material to be extracted faster, and the comb teeth 6 at the bottoms of the right clamping plate 4 and the left clamping plate 5 are meshed, so that the extracted material will not slip from the splicing gap between the right clamping plate 4 and the left clamping plate 5 due to gravity, effectively improving the extraction stability of the power-assisted manipulator. One mounting shaft 3 is fixedly connected to the right clamping plate 4, and the other mounting shaft 3 is fixedly connected to the left clamping plate 5.

[0024] Please refer to Figures 2-4, the hydraulic transmission assembly 7 includes four transmission seats 71. Two of the transmission seats 71 are respectively fixedly connected to both sides of the top of one side of the right clamping plate 4, and the other two transmission seats 71 are respectively fixedly connected to both sides of the top of one side of the left clamping plate 5. A connecting shaft 72 is rotatably connected between the opposite sides of every two front and rear juxtaposed transmission seats 71. Fixed seats 73 are sleeved on the shaft surfaces of the two connecting shafts 72. A two-way hydraulic cylinder 74 is fixedly connected between the opposite sides of the two fixed seats 73. The connecting shaft 72 is fixedly connected to the fixed seat 73. The two-way hydraulic cylinder 74 is a common hydraulic actuator and is widely used in various mechanical and engineering equipment. Different from a single-acting hydraulic cylinder, the two-way hydraulic cylinder 74 can work in two directions and can provide forward and backward thrusts, thus increasing the flexibility of its application. By activating the contraction switches of the two output ends of the two-way hydraulic cylinder 74, the right clamping plate 4 and the left clamping plate 5 can be simultaneously driven to rotate and adjust between the two connecting seats 2 through the mounting shaft 3, and the rotation directions of the right clamping plate 4 and the left clamping plate 5 are opposite, so that the circular clamping groove between the right clamping plate 4 and the left clamping plate 5 can be opened.

The extraction device is moved by the external assisting manipulator, driving the right clamping plate 4 and the left clamping plate 5 to move downward to the upper part of the material to be extracted, so that the right clamping plate 4 and the left clamping plate 5 are respectively located on both sides of the material. Then, the telescopic switch of the output end of the two-way hydraulic cylinder 74 is activated to drive the right clamping plate 4 and the left clamping plate 5 to move back to their original positions, and the material can be extracted.

[0026] After the right clamping plate 4 and the left clamping plate 5 are spliced, the combs 6 at the bottoms of the right clamping plate 4 and the left clamping plate 5 are engaged with each other, so that the extracted material will not slip out from the splicing gap between the right clamping plate 4 and the left clamping plate 5 due to gravity, effectively improving the extraction stability of the assisting manipulator.

[0027] The combs 6 with beveled sharp corners at the bottoms of the right clamping plate 4 and the left clamping plate 5 are convenient for quickly hooking the material to be extracted, effectively improving the material extraction and transportation efficiency.
