Technical Field

[0001] This utility model relates to the field of clamping structure technology, and in particular to a cylinder clamping structure. Background Technology

[0002] In the current production process of long, irregularly shaped products (with different heights at the front and rear ends), workers usually use manual clamping to attach fixtures. Each time, they need to use measuring tools to align the center, which is time-consuming and greatly reduces production efficiency. Due to individual differences in worker operation, not only is their workload increased, but they also need to have a high level of technical skills, which to some extent limits the expansion of production scale.

[0003] The existing manual clamping method still has the problem of mass production and cannot meet the needs of large-scale industrial production, thus affecting production efficiency and product quality. When workers clamp parts, the pressure applied is inconsistent, which often causes the parts to deform during the clamping process, making it difficult to maintain stable product quality, and further affecting product performance and customer satisfaction.

[0004] Therefore, we propose a cylinder clamp structure. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a cylinder clamping structure that can improve clamping efficiency, reduce the labor intensity of workers, ensure product quality, and realize mass production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cylinder clamping structure includes a clamping base plate, wherein a plurality of first cylinder positioning structures and second cylinder positioning structures are respectively provided on both sides of the top of the clamping base plate.

[0008] The first cylinder positioning structure includes a positioning seat, a first cylinder and a pressure plate. The pressure plate is installed at the output end of the first cylinder. There are two first cylinders, which are symmetrically arranged on both sides of the positioning seat. The positioning seat is installed on the top of the fixture base plate.

[0009] The second cylinder positioning structure includes a pad seat, a second cylinder, and a movable clamping plate. The movable clamping plate is movably connected to the output end of the second cylinder. There are two second cylinders, which are symmetrically arranged on both sides of the pad seat. The pad seat is installed on the top of the fixture base plate.

[0010] The pad seat has a centering positioning cavity through both ends, and a movable groove is opened at the top of the pad seat. The movable groove is connected to the centering positioning cavity, and guide frames are provided on both sides extending to the output end of the second cylinder. The movable clamp is located inside the guide frame.

[0011] Furthermore, the bottom of the positioning seat is fixed to the base plate of the fixture by a pin, and the end of the positioning seat away from the base plate of the fixture is adapted to the product structure.

[0012] Furthermore, the pressure plate extends above the positioning seat and moves closer to / away from the positioning seat via the first cylinder. A plastic pad is bonded and wrapped around the periphery of the pressure plate.

[0013] Furthermore, the bottom of the pad is fixed to the base plate of the fixture by a pin.

[0014] Furthermore, the movable clamping plate is extended and retracted towards / away from the center point of the centering positioning cavity by the second cylinder, and a plastic pad is bonded and wrapped around the periphery of the movable clamping plate.

[0015] Furthermore, the bottom surface of the centering positioning cavity is horizontal to the supporting surface of the positioning seat.

[0016] Furthermore, the fixture base plate is equipped with two independent cylinder switches, which are used to control the first cylinder and the second cylinder respectively.

[0017] Furthermore, the number of the first cylinder positioning structure and the second cylinder positioning structure is no less than two sets.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. Significantly improved clamping efficiency: The clamping operation is carried out by automatically driving the pressure plate and movable clamping plate with a cylinder, eliminating the tedious steps of center alignment with measuring tools each time in the traditional manual clamping method. This greatly shortens the clamping time, effectively improves production efficiency, and can better adapt to the pace of large-scale production.

[0020] 2. Significantly reduces the labor intensity of workers: The automated clamping process reduces the amount of manual operation required by workers and lowers the requirements for workers' operating skills. Workers do not need to perform repetitive and high-intensity manual clamping actions for a long time, which reduces the burden on their bodies, helps to improve work comfort and reduce the occurrence of occupational diseases.

[0021] 3. Stable and reliable product quality: The cylinder provides a stable and uniform clamping force, avoiding product deformation caused by inconsistent pressure when manually clamping by workers. At the same time, the positioning seat is adapted to the product structure and the design of the centering positioning cavity and the positioning seat support surface are horizontal, ensuring the accurate positioning of the product during the clamping process and guaranteeing the stability and consistency of product quality.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] Example 1

[0036] like Figure 1-2 As shown, this utility model provides a technical solution: a cylinder clamping structure, which aims to achieve precise positioning and stable clamping of long strip-shaped products with different front and rear heights during the production process. It mainly includes a clamping base plate 1, which serves as the basic support component of the entire clamping device. Several sets of first cylinder positioning structures 2 and second cylinder positioning structures 3 are respectively provided on both sides of its top end.

[0037] The first cylinder positioning structure 2 includes a positioning seat 21, a first cylinder 22, and a pressure plate 23. The pressure plate 23 is installed at the output end of the first cylinder 22. There are two first cylinders 22, which are symmetrically arranged on both sides of the positioning seat 21. The positioning seat 21 is installed at the top of the fixture base plate 1. Its function is to provide a stable positioning reference surface for the product. The first cylinder 22 drives the pressure plate 23 to move closer to or away from the positioning seat 21 through telescopic movement, thereby realizing the clamping or releasing operation of the product. The two first cylinders 22 are symmetrically arranged, which can ensure that the pressure plate 23 is subjected to uniform force when clamping the product, and avoid the product from shifting or deforming due to uneven force.

[0038] The second cylinder positioning structure 3 includes a pad seat 31, a second cylinder 32, and a movable clamping plate 33. The movable clamping plate 33 is movably connected to the output end of the second cylinder 32. There are two second cylinders 32, which are symmetrically arranged on both sides of the pad seat 31. The pad seat 31 is installed on the top of the fixture base plate 1. Its structural design is different from that of the positioning seat 21. The pad seat 31 has a centering positioning cavity 4 through both ends. The centering positioning cavity 4 is used to center and position the product to ensure the positional accuracy of the product in the fixture. The top of the pad seat 31 has a movable groove 5, which is connected to the centering positioning cavity 4. Guide frames 6 are provided on both sides extending to the output end of the second cylinder 32. The movable clamping plate 33 is located inside the guide frame 6. The function of the guide frame 6 is to provide guidance for the movement of the movable clamping plate 33, ensuring that the movable clamping plate 33 can accurately approach or move away from the center point of the centering positioning cavity 4 under the drive of the second cylinder 32, thereby achieving precise clamping of the product.

[0039] Example 2

[0040] like Figure 1-2 As shown, the bottom of the positioning seat 21 is fixed to the fixture base plate 1 by a pin. This fixing method not only ensures the connection stability between the positioning seat 21 and the fixture base plate 1, but also facilitates disassembly and replacement when needed. The end of the positioning seat 21 away from the fixture base plate 1 is adapted to the product structure. That is, the shape of the positioning seat 21 is designed according to the shape and size of different products to ensure that the product can be accurately placed on the positioning seat 21 and achieve precise positioning.

[0041] The pressure plate 23 extends above the positioning seat 21 and moves closer to / away from the positioning seat 21 via the extension and retraction of the first cylinder 22. When the first cylinder 22 retracts, the pressure plate 23 moves downward and presses the product placed on the positioning seat 21; when the first cylinder 22 extends, the pressure plate 23 moves upward and releases the product. The pressure plate 23 is covered with a plastic pad, which has good elasticity and friction, and can play a buffering role when clamping the product to avoid damage to the product surface caused by the pressure plate 23. At the same time, it increases the friction between the pressure plate 23 and the product and improves the stability of clamping.

[0042] The bottom of the pad block seat 31 is fixed to the fixture base plate 1 by a pin, similar to the fixing method of the positioning seat 21, which ensures the reliability of the connection between the pad block seat 31 and the fixture base plate 1.

[0043] The movable clamping plate 33 extends and retracts towards / away from the center point of the centering positioning cavity 4 via the second cylinder 32. When the second cylinder 32 extends, the movable clamping plate 33 moves towards the center point of the centering positioning cavity 4, clamping the product placed in the centering positioning cavity 4. When the second cylinder 32 retracts, the movable clamping plate 33 moves away from the center point of the centering positioning cavity 4, releasing the product. The movable clamping plate 33 is also covered with a plastic pad, which serves the same purpose as the plastic pad on the pressure plate 23, both of which are to protect the product surface and improve clamping stability.

[0044] The bottom surface of the centering positioning cavity 4 is level with the supporting surface of the positioning seat 21. This design ensures that the product can remain horizontal when placed on the fixture, which helps to improve the positioning accuracy and processing quality of the product.

[0045] In addition, the fixture base plate 1 is equipped with two independent cylinder switches 7, which are used to control the first cylinder 22 and the second cylinder 32 respectively. The operator can operate the cylinder switches 7 to independently control the extension and retraction of the first cylinder 22 and the second cylinder 32, so as to realize the step-by-step clamping or releasing operation of the product, which improves the flexibility and convenience of operation.

[0046] The number of the first cylinder positioning structure 2 and the second cylinder positioning structure 3 shall not be less than two sets. Setting multiple sets of positioning structures can further improve the clamping stability and positioning accuracy of the fixture on the product.

[0047] The working process of this utility model is as follows: When using a cylinder clamping structure, the product is first placed on the positioning seat 21, so that one side of the product is closely attached to the positioning surface of the positioning seat 21 to achieve preliminary positioning. At the same time, the other part of the product is placed in the centering positioning cavity 4 of the pad seat 31. The product is centered and positioned by the centering positioning cavity 4 to ensure the positional accuracy of the product in the clamp.

[0048] Next, the cylinder switch 7 controlling the first cylinder 22 is operated to retract the first cylinder 22, which drives the pressure plate 23 to move downward and press the product, so that the product is firmly fixed on the positioning seat 21. During the process of the pressure plate 23 pressing the product, the plastic pad around the pressure plate 23 can play a buffering and protective role, preventing the pressure plate 23 from damaging the surface of the product.

[0049] Then, the cylinder switch 7 of the second cylinder 32 is operated to extend the second cylinder 32, which drives the movable clamping plate 33 to move towards the center point of the centering positioning cavity 4, clamping the product placed in the centering positioning cavity 4. The plastic pad around the movable clamping plate 33 can also protect the product surface and improve the clamping stability.

[0050] After the product is securely clamped, subsequent processing operations can be performed. After processing is completed, first operate the cylinder switch 7 that controls the second cylinder 32 to retract the second cylinder 32, which will move the movable clamping plate 33 away from the center point of the centering positioning cavity 4 and release the product. Then, operate the cylinder switch 7 that controls the first cylinder 22 to extend the first cylinder 22, which will move the pressure plate 23 upward and release the product. Finally, remove the processed product from the fixture to complete the entire processing process.

[0051] If you need to process products of different shapes or sizes, simply repeat the above steps, replace the corresponding positioning seat 21 and pad seat 31, and readjust the product placement and clamping method.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
