[0003] For example, an invention patent with application number CN201711413023.5 provides a pneumatic clamp, including a push cylinder, a guide block, a push head, a roller, an upper support block, a lower support block, a guide shaft, an upper claw, and a lower claw; the front end of the push cylinder is connected to the push head; the push head is provided with two oppositely arranged bevel blocks; the two bevel blocks are separated by a distance; the backs of the two bevel blocks are respectively embedded in the guide grooves of the guide blocks arranged on the outer sides thereof; the inclined surfaces of the two bevel blocks are opposite and open toward the front; the upper support block and the lower support block are oppositely arranged and located on the inner sides of the two guide blocks; a roller is respectively connected to the same position of the side of the upper support block and the lower support block; the bevel block of the push head is wedged between the roller and the guide block; the upper claw is connected to the upper support block, and the lower claw is connected to the lower support block. Guide holes are provided on both the upper support block and the lower support block, and are sleeved on the guide shaft.

[0004] For example, the above-mentioned technical solution realizes picking up by moving the left and right fingers closer or further away. However, due to the gravity of the workpiece itself, there is friction between the two, so it is easy to wear, slip, etc. It is not suitable for workpieces with high surface requirements, so there is a lot of room for improvement. Summary of the invention

[0005] The purpose of the present invention is to propose a power clamp to address the above problems in the prior art.

[0006] The purpose of the present invention can be achieved through the following technical solutions: A power clamp, comprising:

[0007] Drive device;

[0008] There are two movable seats, both of which are connected to the driving device, and the driving device can drive the two movable seats to move closer to or away from each other, and the movable seats have a positioning portion;

[0009] There are two rotating arms corresponding to the movable seats one by one, one end of the rotating arm is movably connected to the driving device, the middle part of the rotating arm is rotatably connected to the movable seat, the other end of the rotating arm is formed as a clamping portion, and a clamping space is formed between the clamping portion and the positioning portion;

[0010] When the driving device drives the two moving seats to move away from each other, the moving seat drives the rotating arm to rotate so that the clamping part approaches the positioning part. When the driving device drives the two moving seats to move towards each other, the moving seat drives the rotating arm to rotate so that the clamping part moves away from the positioning part.

[0011] In the above-mentioned power clamp, the clamping portion is provided with a contact wheel, the contact wheel is rotatably connected to the clamping portion, and the contact wheel is used to contact the workpiece.

[0012] In the above-mentioned power clamp, the movable seat also has a first hidden groove, and the rotating arm is located in the first hidden groove. When the driving device drives the two movable seats to move away from each other, the rotating arm extends out of the first hidden groove, and when the driving device drives the two movable seats to move closer to each other, the rotating arm retracts into the first hidden groove.

[0013] In the above-mentioned power clamp, the contact wheel is a flexible member.

[0014] In the above-mentioned power clamp, the positioning portion is provided with a contact block, the surface of the contact block is higher than or equal to the surface of the positioning portion, and the contact block is used to contact the workpiece.

[0015] In the above-mentioned power clamp, the movable seat further has a second hidden groove, and the contact block is located in the second hidden groove.

[0016] In the above-mentioned power clamp, the contact block is a flexible member.

[0017] In the above-mentioned power clamp, it also includes a movable seat, which is connected to the driving device in a liftable manner, and the rotating arm is rotatably connected to the movable seat.

[0018] In the above-mentioned power clamp, the driving device is provided with two sliders, and the driving device can drive the two sliders to move closer to or away from each other, and the two moving seats are respectively connected to the two sliders.

[0019] In the above-mentioned power clamp, the driving device is a pneumatic cylinder, a hydraulic cylinder or an electric cylinder.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. When the driving device drives the two moving seats away from each other, the moving seats drive the rotating arm to rotate so that the clamping part is close to the positioning part, so that the clamping part is rotated from the original position to lift the workpiece until the workpiece contacts the positioning part to complete the clamping, thereby completing the stable picking of the workpiece, not easily wearing the workpiece, and not causing the workpiece to slip.

[0022] 2. The clamping part contacts the workpiece through the contact wheel. Therefore, when the arm rotates and lifts the workpiece, the contact wheel can convert the sliding of the clamping part at the bottom of the workpiece into sliding friction, further reducing the wear on the workpiece.

[0023] 3. When the power clamp is not working, the rotating arm retracts into the first hidden groove. At this time, the movable seat can well protect the power clamp through the first hidden groove. Meanwhile, the first hidden groove can also assist in guiding the rotation of the rotating arm.

[0026] 6. The contact block is located in the second hidden groove, so that the contact block is not easy to fall off the moving seat. At the same time, the contact block is reinforced by the wall surface around the second hidden groove, thereby increasing the strength of the contact block.

[0027] 7. The contact block is set as a flexible part, so that the contact between the contact block and the workpiece is flexible contact, further reducing the wear on the workpiece. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0040] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0041] like Figure 1-Figure 6 As shown, a power clamp includes: a driving device 100, a movable base 200 and a rotating arm 300. This design aims to provide an efficient and precise workpiece 500 clamping solution, which is suitable for a variety of industrial application scenarios.

[0042] The driving device 100 is a pneumatic cylinder, a hydraulic cylinder or an electric cylinder.

[0043] Specifically, the driving device 100 is provided with two sliders 110 , and the driving device 100 can drive the two sliders 110 to move closer to or away from each other, and the two moving seats 200 are respectively connected to the two sliders 110 .

[0044] There are two movable seats 200 , and both of the two movable seats 200 are connected to the driving device 100 . The driving device 100 can drive the two movable seats 200 to move closer to or farther from each other. The movable seats 200 have a positioning portion 210 .

[0045] The movable seat 200 has a positioning portion 210 for cooperating with other components to achieve a stable and accurate clamping function.

[0046] The design of the positioning part 210 takes into account the shape and size of the workpiece 500 to ensure that the workpiece 500 will not be damaged during the clamping process. In addition, the movable seat 200 is usually made of high-strength materials to ensure its durability in long-term use. Compared with traditional clamps, this design effectively avoids the wear problem caused by frequent use and prolongs the service life of the equipment.

[0047] Among them, there are two rotating arms 300 and they correspond one to one with the movable seat 200. One end of the rotating arm 300 can be movably connected to the driving device 100, and the middle part of the rotating arm 300 can be rotatably connected to the movable seat 200. The other end of the rotating arm 300 is formed as a clamping part 310, and a clamping space for clamping the workpiece 500 is formed between the clamping part 310 and the positioning part 210.

[0048] This design enables the rotating arm 300 to flexibly adjust its position under the action of the driving device 100 to ensure the smooth progress of the clamping process. The rotating arm 300 is usually made of lightweight but strong material to reduce the overall weight and improve the response speed. Compared with traditional fixed clamps, it provides greater flexibility and is suitable for processing workpieces 500 of different shapes and sizes.

[0049] Specifically, it further includes a movable seat 400 , which is liftably connected to the driving device 100 , and the rotating arm 300 is rotatably connected to the movable seat 400 , so that one end of the rotating arm 300 is movable relative to the driving device 100 .

[0050] This feature further enhances the flexibility of the system, enabling it to adapt to more complex clamping tasks. For example, when processing irregularly shaped or larger-sized workpieces 500, the lifting function of the movable seat 400 can significantly improve the operating range and efficiency of the clamping jaws.

[0051] It is worth noting here that the minimum number condition is that the number of the rotating arms 300 is two. In fact, the number of the rotating arms 300 can be any number, and the number of the rotating arms 300 located on the single-side movable seat 200 is at least one.

[0052] When the driving device 100 drives the two movable seats 200 to move away from each other, the movable seats 200 drive the rotating arm 300 to rotate so that the clamping portion 310 is close to the positioning portion 210 , thereby completing the clamping of the workpiece 500 .

[0053] On the contrary, when the driving device 100 drives the two moving seats 200 to approach each other, the moving seats 200 drive the rotating arm 300 to rotate so that the clamping portion 310 moves away from the positioning portion 210 and the workpiece 500 is released.

[0054] In existing technologies, traditional gripper systems usually rely on complex mechanical structures and manual adjustments, which not only increases the difficulty of operation but also limits its flexibility and adaptability.

[0055] In this embodiment, when the driving device 100 drives the two movable seats 200 to move away from each other, the movable seat 200 drives the rotating arm 300 to rotate so that the clamping part 310 is close to the positioning part 210, so that the clamping part 310 is rotated from the original position to be able to lift the workpiece 500 until the workpiece 500 is brought into contact with the positioning part 210 to complete the clamping, thereby completing the stable picking up of the workpiece 500, not easily wearing the workpiece 500, and not causing the workpiece 500 to slip.

[0056] like Figure 1-Figure 6 As shown, on the basis of the above embodiment, the clamping portion 310 is provided with a contact wheel 311 , and the contact wheel 311 is rotatably connected to the clamping portion 310 , and the contact wheel 311 is used to contact the workpiece 500 .

[0057] This design not only reduces friction, but also further protects the surface of the workpiece 500 from damage. In practical applications, the contact wheel 311 can select different surface treatment methods according to the specific material of the workpiece 500 to achieve the best protection effect.

[0058] For example, for a fragile workpiece 500 , a contact wheel 311 with a rubber coating may be selected to provide better cushioning and anti-slip performance.

[0059] In this embodiment, the clamping portion 310 contacts the workpiece 500 through the contact wheel 311. Therefore, when the rotating arm 300 rotates and lifts the workpiece 500, the contact wheel 311 can convert the sliding of the clamping portion 310 at the bottom of the workpiece 500 into sliding friction, further reducing the wear on the workpiece 500.

[0060] like Figure 1-Figure 6 As shown, based on the above embodiment, the movable seat 200 also has a first hidden groove 220, and the rotating arm 300 is located in the first hidden groove 220. When the driving device 100 drives the two movable seats 200 to move away from each other, the rotating arm 300 extends out of the first hidden groove 220, and when the driving device 100 drives the two movable seats 200 to move closer to each other, the rotating arm 300 retracts into the first hidden groove 220.

[0061] This not only protects the rotating arm 300, but also improves the safety and aesthetics of the overall equipment. The design of the hidden groove can also prevent external dust and debris from entering, thereby extending the service life of the equipment.

[0062] In this embodiment, when the power clamp is not working, the rotating arm 300 retracts into the first hidden groove 220. At this time, the movable seat 200 can well protect the power clamp through the first hidden groove 220. At the same time, the first hidden groove 220 can also assist in guiding the rotation of the rotating arm 300.

[0063] like Figure 1-Figure 6 As shown, based on the above embodiment, the contact wheel 311 is a flexible member.

[0064] In this embodiment, the contact wheel 311 is configured as a flexible member, so that the contact between the contact wheel 311 and the workpiece 500 is a flexible contact, further reducing the wear on the workpiece 500 .

[0065] like Figure 1-Figure 6 As shown, on the basis of the above embodiment, the positioning portion 210 is provided with a contact block 211 , the surface of the contact block 211 is higher than or equal to the surface of the positioning portion 210 , and the contact block 211 is used to contact the workpiece 500 .

[0066] Specifically, the contact block 211 and the rotating arm 300 correspond in position up and down.

[0067] The contact block 211 is usually made of wear-resistant material and can be customized according to the surface characteristics of the workpiece 500 to ensure the best clamping effect.

[0068] In this embodiment, the contact block 211 can be provided with a contact block 211 whose surface is higher than or equal to its own surface through the positioning portion 210. The positioning portion 210 contacts the top of the workpiece 500 through the contact block 211. When the rotating arm 300 lifts the workpiece 500 through the clamping portion 310, the two can firmly clamp the workpiece 500.

[0069] like Figure 1-Figure 6 As shown, based on the above embodiment, the movable seat 200 further has a second hidden groove 230 , and the contact block 211 is located in the second hidden groove 230 .

[0070] In this embodiment, the contact block 211 is located in the second hidden groove 230, so that the contact block 211 is not easy to fall off the movable seat 200. At the same time, the wall surface around the second hidden groove 230 reinforces the contact block 211, thereby increasing the strength of the contact block 211.

[0071] like Figure 1-Figure 6 As shown, based on the above embodiment, the contact block 211 is a flexible member.

[0072] In this embodiment, the contact block 211 is configured as a flexible member, so that the contact between the contact block 211 and the workpiece 500 is a flexible contact, further reducing the wear on the workpiece 500 .

[0073] It is worth mentioning that the power gripper is widely used in automated production lines, storage and logistics systems, and various precision processing equipment. Its high flexibility and precision enable it to handle workpieces 500 of various shapes and sizes, greatly improving work efficiency and product quality. Especially in applications where the type of workpiece 500 needs to be frequently changed, the quick adjustment capability of the gripper is particularly important.

[0074] For example, in the automotive industry, the power gripper can quickly adapt to the gripping needs of different types of parts, greatly improving production efficiency. In addition, in the field of electronic product manufacturing, the gripper can accurately handle small and fragile components to ensure the high quality standards of the products.

[0075] In summary, this power gripper ensures high efficiency and reliability in various application scenarios through multi-faceted detail optimization. Its unique design not only improves the accuracy of operation, but also effectively reduces the risk of damage to the workpiece 500.
