Technical Field
[0001] The utility model relates to the technical field of mechanical claws, in particular to a rotating clamping type transporting mechanical claw. Background Art
[0002] The rotary clamping handling robot claw is a highly efficient clamping device for automated handling tools. It usually includes components such as a mechanical claw part, an oil or gas control system, etc. The design of this mechanical claw allows it to achieve 360° rotation when handling items to adapt to different working environments and requirements. The rotary clamping handling robot claw is widely used in industrial manufacturing, automated production, logistics and transportation, etc. It can be installed on a robotic arm, forklift or automated equipment to solve the problem of loading and unloading, improve production efficiency and reduce manual labor.
[0003] The existing rotary clamping type handling mechanical claws are roughly divided into two categories: parallel claws and arc-shaped claws. Parallel claws are mainly suitable for clamping objects with flat surfaces, and arc-shaped claws are mainly suitable for round or arc-shaped objects. However, when using them to deal with objects of different shapes, different types of rotary clamping type handling mechanical claws need to be replaced, which cannot be universal because different rotary clamping type handling mechanical claws have different contact surfaces when clamping objects of different shapes. For example, when the parallel claws clamp round objects, the contact area is too small due to the influence of the arc angle, and the round objects cannot be clamped or moved. In order to solve this technical problem, the utility model proposes a rotary clamping type handling mechanical claw. Utility Model Content
[0004] The main purpose of the utility model is to provide a rotating clamping type handling mechanical claw, which can effectively solve the problems mentioned in the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A rotary clamping type handling mechanical claw comprises a support frame, a slide rail, two parallel clamps and two arc-shaped clamps, wherein the slide rail is installed inside the support frame, the inner wall of the slide rail is slidably connected to the two parallel clamps, and the two parallel clamps are symmetrically arranged, two first hydraulic cylinders are arranged inside the support frame, the two arc-shaped clamps are respectively arranged inside the two parallel clamps, and second hydraulic cylinders are arranged outside the two parallel clamps.
[0007] Preferably, the two second hydraulic cylinders are connected to one side of the parallel clamping jaws, and the output ends of the two second hydraulic cylinders are connected to one side of the arc-shaped clamping jaws.
[0008] Preferably, one side of the parallel clamping jaw is connected to a sliding seat, the inner wall of the sliding seat is slidably connected to a guide rod, and one end of the guide rod is connected to one side of the arc-shaped clamping jaw.

[0010] Preferably, the outer surface of the support frame is rotatably connected to a connecting seat, a hydraulic motor is installed outside the connecting seat, and an output shaft of the hydraulic motor is connected to a gear.
[0011] Preferably, an outer gear ring is installed on the outer surface of the support frame, and the outer gear ring is meshingly connected with the gear.
[0012] Preferably, the fixed ends of the two first hydraulic cylinders are connected to the inner wall of the support frame, the output ends of the two first hydraulic cylinders are connected to one side of the parallel clamps, and the other side of the parallel clamps is installed with an anti-slip pad.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 1. In the utility model, through the cooperation between the second hydraulic cylinder, the arc-shaped clamp and the parallel clamp, the parallel clamp can drive the arc-shaped clamp to a position close to the round object by moving. The second hydraulic cylinder can provide thrust for the arc-shaped clamp so that the arc-shaped clamp has a clamping force on the round object. When not in use, the second hydraulic cylinder can drive the arc-shaped clamp to be retracted into the parallel clamp. When the parallel clamp is in use, the arc-shaped clamp will not cause obstruction. If it is not necessary to replace the arc-shaped clamp and the parallel clamp, universality is achieved, and both round objects and flat objects can be clamped.
[0015] 2. In the utility model, through the cooperation between the outer gear ring, the gear and the hydraulic motor, the outer gear ring can receive power for the support frame, and the power provided by the hydraulic motor can drive the gear to rotate. After the gear rotates, it can drive the outer gear ring to rotate, and the outer gear ring drives the support frame to rotate. The rotation of the support frame drives the objects to rotate, and the placement angle of the objects can be adjusted. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0021] 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 described below in conjunction with specific implementation methods.
[0022] like Figure 1-4 As shown, a rotary clamping type handling mechanical claw comprises a support frame 1, a slide rail 2, two parallel clamps 3 and two arc-shaped clamps 4. The slide rail 2 is installed inside the support frame 1. The inner wall of the slide rail 2 is slidably connected to the two parallel clamps 3, and the two parallel clamps 3 are symmetrically arranged. The parallel clamps 3 are pushed to move by the power provided by the first hydraulic cylinder 5. When the parallel clamps 3 move, the slide rail 2 is used to increase stability and provide supporting force. The fixed ends of the two first hydraulic cylinders 5 are connected to the inner wall of the support frame 1, and the output ends of the two first hydraulic cylinders 5 are connected to one side of the parallel clamps 3. Two first hydraulic cylinders 5 are arranged inside the support frame 1, and the first hydraulic cylinders 5 provide power for the sliding of the parallel clamps 3, push the parallel clamps 3 to move, and shrink the distance between the parallel clamps 3 to apply clamping force to the objects to be clamped and control the clamping force. An anti-skid pad 14 is installed on the other side of the parallel clamps 3. The anti-skid pad 14 is made of rubber. The rubber anti-skid pad 14 has a good anti-skid effect. At the same time, the rubber anti-skid pad 14 has toughness and elasticity, and can activate the buffering effect to prevent the parallel clamps 3 from clamping too hard and causing damage to the objects.
[0023] The two arc-shaped clamps 4 are respectively arranged inside the two parallel clamps 3, and the second hydraulic cylinder 6 is arranged outside the two parallel clamps 3. The second hydraulic cylinder 6 provides power for the arc-shaped clamps 4 to move their positions, and pushes the arc-shaped clamps 4 to move their positions. The two second hydraulic cylinders 6 are both connected to one side of the parallel clamps 3, and the output ends of the two second hydraulic cylinders 6 are both connected to one side of the arc-shaped clamps 4. The second hydraulic cylinder 6 provides power for the arc-shaped clamps 4 to move their positions, and pushes the arc-shaped clamps 4 to move their positions. By pushing the arc-shaped clamps 4 to move and shrink the distance between the two, the clamping force is applied to the objects to be clamped and the clamping force is controlled.
[0024] The cam 8 is connected to one side of the parallel clamping jaw 3, and the inner wall of the slide seat 7 is slidably connected to a guide rod 8, and one end of the guide rod 8 is connected to one side of the arc-shaped clamping jaw 4 through the slide seat 7 to support the guide rod 8, thereby increasing the stability of the guide rod 8, so that the guide rod 8 has more stability when subjected to force. Only then can the guide rod 8 provide supporting force for the arc-shaped clamping jaw 4 more stably, and increase the arc-shaped clamping jaw 4 After clamping the object, the object can be supported more stably when loaded.
[0025] The outer surface of the support frame 1 is rotatably connected to a connecting seat 10, and a hydraulic motor 11 is installed on the outside of the connecting seat 10. The output shaft of the hydraulic motor 11 is connected to a gear 12. The hydraulic motor 11 rotates to provide power, which drives the gear 12 to rotate, providing motive force for driving the support frame 1 to rotate. An outer gear ring 13 is installed on the outer surface of the support frame 1. The support frame 1 receives power through the outer gear ring 13, and the outer gear ring 13 is meshed with the gear 12. When the gear 12 rotates, the outer gear ring 13 is driven to rotate, and the outer gear ring 13 drives the support frame 1 to rotate. The rotation of the support frame 1 drives the objects to rotate, and the placement angle of the objects can be adjusted.
[0026] When it is necessary to clamp a flat object, first start the first hydraulic cylinder 5 to push the parallel jaws 3 to move. When the first hydraulic cylinder 5 pushes the parallel jaws 3 to move, the two parallel jaws 3 shrink inward at the same time to clamp the flat object. When it is necessary to clamp a round object, first push the parallel jaws 3 to move close to the round object through the first hydraulic cylinder 5, and then start the second hydraulic cylinder 6 to push the arc-shaped jaws 4 to shrink toward the round object. Then the arc-shaped clamping plate 9 contacts the round object and then clamps the round object. When the arc-shaped jaws 4 are not in use, it is only necessary to shrink the second hydraulic cylinder 6 to drive the arc-shaped jaws 4 to shrink into the inside of the parallel jaws 3. When the parallel jaws 3 are in use, the arc-shaped jaws 4 will not block the parallel jaws 3.
