DETAILED DESCRIPTION

[0032] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1:

[0035] Please see the attached Figure 1 -Attached Figure 2 , of which Figure 2The X direction is movement toward the center of the base 1; the Y direction is movement away from the center of the base 1. The present invention provides a clamp, comprising a base 1, a clamping assembly, and a drive assembly 3. The base 1 is provided with a circular array of sliding grooves 11. The clamping assembly includes clamping members 21, which are movably connected to the sliding grooves 11, with the area between adjacent clamping members 21 forming a movable area 22. The clamping members 21 and the base 1 enclose a clamping cavity 23 for placing products. The drive assembly 3 is drivably connected to the clamping assembly, allowing the clamping members 21 to move within the sliding grooves 11.

[0036] There are five sliding grooves 11, corresponding to five clamping members 21. The sliding grooves 11 are used to move the clamping members 21, and the positions of the clamping members 21 in the sliding grooves 11 can be adjusted according to the product size. That is, the closer the clamping member 21 is to the middle of the base 1, the smaller the product size will be.

[0037] The active area 22 is used for the movable range of the clamping piece 21 when the clamping assembly is performing loosening and tightening operations. When the clamping assembly is tightened, the clamping piece 21 moves in the X direction, that is, adjacent clamping pieces 21 are close to each other, and the active area 22 becomes smaller; when the clamping assembly is loosened, the clamping piece 21 moves in the Y direction, that is, adjacent clamping pieces 21 are away from each other, and the active area 22 becomes larger. The setting of the active area 22 can ensure the adequacy of clamping and the stability of clamping.

[0038] The clamp in this embodiment operates as follows: before clamping, the clamping assembly is in a relaxed state, allowing the product to be placed in the clamping cavity 23. Once the product enters the clamping cavity 23, the drive assembly 3 drives the clamping member 21 to move in the X direction, thereby shrinking the clamping cavity 23 until the product is firmly locked in the clamping cavity 23. When the product needs to be released, the drive assembly 3 drives the clamping member 21 to move in the Y direction, and the active area 22 and the clamping cavity 23 expand accordingly, allowing the product to escape from the clamping member 21 and be easily removed from the clamping cavity 23.

[0039] Through the circular array of sliding slots 11 arranged on the base 1, the position of the clamping member 21 within the sliding slot 11 can be determined according to the size of the product, and the corresponding clamping member 21 can be replaced accordingly to meet the clamping function of products of different sizes. The structure of this embodiment does not require the replacement of the entire clamp, but only requires the switching of the clamping member 21 that is compatible with the product. The switching operation is simple, convenient for adapting to products of different sizes, and has a wide range of applications and strong practicality.

[0040] In addition, the overall structural design of the clamp in this embodiment is simple and reasonable, the production cost is low, and it is easy to operate and switch the clamp to cope with different products, thereby improving the ease and convenience of operation.

[0041] Example 2:

[0042] The difference between this embodiment and embodiment 1 is that, see Figure 3 In this embodiment, the sliding groove 11 is provided with a clamping groove 111, and the clamping member 21 is embedded in the clamping groove 111 and slidably connected to the clamping groove; the sliding groove 11 is formed into a T-shaped sliding groove. Through this arrangement, the clamping member 21 is embedded in the clamping groove 111 and moves within the clamping groove 111. The clamping groove 111 provides a limit for the movement of the clamping member 21, effectively ensuring the stability of the clamping member 21 during the tightening and loosening operation, and ensuring that multiple clamping members 21 are on the same plane during the movement, avoiding the deviation of the clamping members 21, ensuring the balance of the clamping force, and avoiding the phenomenon of uneven clamping force on the product causing damage to the product, thereby effectively protecting the product.

[0043] In some embodiments, see Figure 4 The clamping assembly also includes a sliding block 24 and a connecting block 25. One end of the connecting block 25 is connected to the clamping piece 21, and the other end of the connecting block 25 is connected to the sliding block 24. The sliding block 24 is driven and connected to the driving assembly 3. The specific action is: when the clamping piece 21 needs to clamp the product, the driving assembly 3 drives the sliding block 24 to move in the X direction, and then the connecting block 25 moves accordingly, and drives the clamping piece 21 to move in the X direction, so that the space of the active area 22 and the clamping cavity 23 is reduced, and the function of clamping the product is realized. When the clamping piece 21 needs to release the product, the driving assembly 3 drives the sliding block 24 to move in the Y direction, and then the connecting block 25 moves accordingly, and drives the clamping piece 21 to move in the Y direction, so that the space of the active area 22 and the clamping cavity 23 is expanded, and the function of releasing the product is realized. Through this setting, the linkage of each component is smooth, the mechanical action process is not redundant, the beat is strong, and the clamping response efficiency is fast.

[0044] In some embodiments, a flat key 251 is provided at one end of the connecting block 25 near the clamping member 21, and a key slot 211 is provided on the clamping member 21 corresponding to the flat key 251. The flat key 251 is interlocked with the key slot 211. Through this arrangement, the flat key 251 and the key slot 211 are interlocked, realizing a locking method in which the flat key 251 replaces a screw, satisfying the positioning function between the connecting block 25 and the clamping member 21. The use of the flat key 251 can effectively improve the bearing capacity of the clamping member 21, avoiding the phenomenon of breakage caused by hot spinning or when a large force is applied when using a screw locking method, thereby ensuring a reliable and secure connection between the connecting block 25 and the clamping member 21.

[0045] In addition, the connection method using the flat key 251 can effectively reduce the installation gap between the connecting block 25 and the clamping piece 21, improve the installation stability, and this setting facilitates the replacement of the clamping piece 21, making the operation simpler and easier.

[0046] In some embodiments, the drive assembly 3 is positioned in the central region of the base 1 and abuts against the sliding blocks 24. This arrangement allows the movement of the drive assembly 3 to drive the sliding blocks 24 in response, thereby driving the clamping member 21 to clamp or release the product. This ingenious overall structural design, with the drive assembly 3 positioned in the central region of the base 1, allows for a relatively even movement of the circular array of sliding blocks 24, ensuring that the multiple sliding blocks 24 move in unison to achieve the clamping function.

[0047] In some embodiments, the driving assembly 3 includes a push block 31, a pull rod 32, and a power element 33. The push block 31 is connected to the pull rod 32, and the power element 33 is driven and connected to the pull rod 32. Specifically, the pull rod 32 and the push block 31 can be fixedly connected by a nut with a washer. Preferably, the power element 33 can adopt a rotary cylinder to push the pull rod 32 to move in the W direction or the Z direction, so that the push block 31 moves in the W direction or the Z direction along with the pull rod 32. The overall structure of this setting is simple and compact, and the action process rhythm is strong.

[0048] For details, see Figure 5 The push block 31 is provided with a push groove 34 corresponding to the sliding block 24, and the sliding block 24 is embedded in the push groove 34 for sliding connection; the push groove 34 is provided with a first inclined surface 311 opposite to the push groove 34, and the sliding block 24 is provided with a second inclined surface 241 that is arranged to abut against the first inclined surface 311. Through the arrangement of the push groove 34, the first inclined surface 311, and the second inclined surface 241, when the push block 31 moves in the W direction, the push groove 34 moves in the W direction. Due to the abutting movement of the first inclined surface 311 and the second inclined surface 241, the vertical movement is converted into a horizontal movement, that is, the sliding block 24 moves in the X direction, driving the clamping member 21 to move in the X direction, thereby realizing the function of the clamping member 21 clamping the product. Similarly, when the push block 31 moves in the Z direction, the push groove 34 moves in the Z direction, the sliding block 24 moves in the Y direction, thereby driving the clamping member 21 to move in the Y direction, thereby realizing the function of the clamping member 21 releasing the product. This structural setting makes the overall structure simple to operate, the mechanical linkage efficiency is high, the manufacturing cost is low, and it is conducive to later maintenance.

[0049] In addition, by setting the pushing groove 34, a guiding and limiting function can be provided for the movement of the sliding block 24, ensuring the stability of the sliding block 24 in the W direction or Z direction, ensuring smooth movement, and at the same time avoiding the lifting and tilting of the pushing block 31, thereby ensuring the clamping stability of the clamping piece 21.

[0050] In some embodiments, there are 4-6 push slots, preferably 5. The number of push slots can be flexibly adjusted based on actual conditions and production requirements, improving flexibility. This arrangement also ensures that each part of the product is clamped firmly, ensuring the stability of the clamping.

[0051] In some embodiments, see Figure 7 The sliding block 24 is provided with a lubricating oil groove 242. Specifically, the lubricating oil groove 242 is used to store lubricating oil. This configuration allows the lubricating oil in the lubricating oil groove 242 to flow between the push block 31 and the sliding block 24, thereby reducing friction between the push block 31 and the sliding block 24, preventing jamming, improving the movement sensitivity between the push block 31 and the sliding block 24, ensuring smooth linkage, and achieving smooth and stable material clamping.
