[0026] To make the technical solution and advantages of this utility model clearer, the exemplary embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not an exhaustive list of all embodiments. Furthermore, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0027] An embodiment of this utility model provides a clamping device for circular end cap-type workpieces. For example... Figures 1 to 4 As shown, the clamping device for circular end cap-type workpieces includes a base plate 1, clamping members 2, and an elastic reset member 3. The base plate 1 is plate-shaped and primarily serves as a basic support. There are multiple clamping members 2, arranged in groups. Each group includes two clamping members 2. One end of each clamping member 2 is connected to the base plate 1, while the other end extends out of the base plate 1 to form a clamping portion 21. The clamping portions 21 of the two clamping members 2 in a group are arranged with a gap between them. At least one clamping member 2 in the group is movably connected to the base plate 1 to adjust the distance between the two clamping portions 21. The elastic reset member 3 is disposed between the base plate 1 and the clamping members 2 movably connected to the base plate 1 to actuate the clamping members 2 to reset.

[0028] During use, a circular end cap-type workpiece 20 is placed between the clamping portions 21 of a set of clamping members 2 for restraint. Specifically, when the circular end cap-type workpiece 20 needs to be clamped, the clamping member 2, which is movably connected to the base plate 1, moves relative to the base plate 1, increasing the distance between the two clamping portions 21 to open them, facilitating the entry of the circular end cap-type workpiece 20 between the two clamping portions 21. After the circular end cap-type workpiece 20 is in place, under the action of the elastic reset member 3, the moving clamping member 2 performs a reset movement to stably clamp the circular end cap-type workpiece 20. It can be seen that the clamping device for circular end cap-type workpieces of this application has a simple structure. The clamping member 2 can automatically reset under the elastic reset member 3, making the clamping operation simple. By adjusting the parameters of the elastic clamping member 3, the clamping force can be effectively guaranteed, thereby stably restraining the circular end cap-type workpiece 20. Furthermore, using this clamping device for circular end cap-type workpieces, high-efficiency oxidation treatment of the circular end cap-type workpiece 20 can be ensured.

[0029] In one embodiment, two of the clamping members 2 in a set of clamping members 2 are connected to the base plate 1 via an elastic reset member 3. In this configuration, both clamping members 2 can move relative to the base plate 1, thus the distance between them can be adjusted over a relatively large range, making adjustment flexible. However, the structure is relatively complex, which increases manufacturing costs.

[0030] In another embodiment, one of the set of clamping members 2 is fixedly connected to the base plate 1. Figure 1 The clamping member 2 is marked as 2'. Another clamping member 2 in a set is connected to the base plate 1 via a resilient reset member 3. Figure 1 The clamping member 2 is marked as "2". In this configuration, the distance between the two clamping parts 21 in a set can be adjusted by the movement of another clamping member 2", to ensure the requirements of use are met. Furthermore, this structure can reduce the number of elastic reset members 3, simplify the structure, and reduce manufacturing costs.

[0031] In one embodiment, the elastic reset element 3 is a torsion spring. In the connection, one end of the torsion spring is fixed to the base plate 1, while the other end of the torsion spring is fixed to the clamping element 2". This arrangement can take advantage of the torsion spring's simple structure and low manufacturing cost.

[0032] A support column 4 is provided on the base plate 1. A torsion spring is sleeved onto the outer wall of the support column 4. It can be seen that the position of the torsion spring on the base plate 1 is defined by the support column 4. One end of the torsion spring is fixed to the support column 4. That is, one end of the torsion spring is fixed to the base plate 1 by the support column 4. Specifically, a snap-fit ​​groove 41 is provided at the free end of the support column 4. The snap-fit ​​groove 41 is a through groove penetrating the side wall of the support column 4. Simultaneously, a straight extension 31 is provided at one end of the torsion spring. The straight extension 31 snaps into the snap-fit ​​groove 41. This design simplifies the installation of the torsion spring and also effectively ensures the positional definition of the torsion spring.

[0033] All clamping components 2 are made of filamentous material. That is, clamping component 2' is constructed as filamentous material and fixed to the base plate 1. Clamping component 2', fixed to the base plate 1, is constructed as filamentous material, while clamping component 2" movably connected to the base plate 1 is integrally connected to the torsion spring; that is, clamping component 2" and the torsion spring are made as a single unit. It is evident that all clamping components 2 are made by machining filamentous metal, which is simple to manufacture and has low production costs. In particular, the other clamping component 2" in a set of clamping components 2 is integrally constructed with the torsion spring and manufactured together with the torsion spring, making manufacturing convenient and inexpensive. Especially, this configuration of the torsion spring allows for rapid response and excellent reset operation.

[0034] A bend is provided on one of the clamping members 2 to form a "V"-shaped clamping part 21. The opening of the "V"-shaped clamping part 21 faces the other clamping part 21. In this application, in order to simplify processing and installation, the clamping member 2' fixed to the base plate 1 in the clamping members 2 can be bent. The clamping member 2" which is movably connected to the base plate 1 is constructed in a straight line. On the one hand, during the clamping process, the "V"-shaped clamping part 21 has two contact points with the circular end cap type workpiece 20. With the clamping of the other clamping member 2", the circular end cap type workpiece 20 can be stably constrained between the two clamping parts 21, ensuring clamping stability and preventing the circular end cap type workpiece 20 from falling off. On the other hand, the "V"-shaped clamping part 21 can be adapted to circular end cap type workpieces 20 of different diameters, which can ensure that the clamping device for circular end cap type workpieces has a wider range of applications.

[0035] Clamping member 2' of a set of clamping members 2 is fixedly connected to the fixing block 5. The fixing block 5 is fixed to the base plate 1. For example, clamping member 2' is connected to the fixing block 5 by welding. This structure makes it easy to set the filamentous clamping member 2' onto the base plate 1.

[0036] A pressure strip 6 is provided on the fixing block 5. The clamping member 2 extends through the gap between the pressure strip 6 and the base plate 1. For example, the fixing block 5 and the pressure strip 6 are connected in sequence by connecting bolts 7 passing through the base plate 1, the fixing block 5 and the pressure strip 6 relative to the base plate 1. In particular, the clamping part 21 at the other end of the torsion spring can extend through the gap between the pressure strip 6 and the base plate 1. It can be seen that the pressure strip 6 can also limit the position of the clamping part 21, further preventing the torsion spring from falling off.

[0037] The base plate 1 is a long strip. Multiple sets of clamping members 2 are provided on both sides of the base plate 1 along its length. On the same side of the base plate 1 along its length, adjacent sets of clamping members 2 are spaced apart to ensure the movement space of the clamping members 2', allowing them to open and place circular end cap-type workpieces 20. To simplify the structure, the clamping members 2' that are fixed to the base plate 1 in corresponding sets of clamping members 2 on both sides of the base plate 1 can be manufactured as a single unit. Of course, the corresponding clamping members 2' also share the same fixing block 5. This structure utilizes two pressure strips 6. These two pressure strips 6 extend along the length of the base plate 1, sequentially fixing all the fixing blocks 5 on both sides of the fixing block 5. In this structure, multiple sets of clamping members 2 can operate simultaneously to simultaneously place multiple circular end cap-type workpieces 20 onto the clamping device for circular end cap-type workpieces, enabling linkage with automated equipment. Furthermore, this structure can complete the clamping of multiple circular end cap-type workpieces 20, resulting in high work efficiency.

[0038] The following is based on Figures 1 to 4 Describe in detail the working principle of the clamping device used for circular end cap workpieces.

[0039] When a circular end cap-type workpiece 20 needs to be clamped, force is applied to the clamping member 2”, increasing the distance between the clamping members 2” and 2” in the set. At this time, the torsion spring at the clamping member 2” is stressed and stores energy. Then, the circular end cap-type workpiece 20 is placed into the clamping part 21. Finally, the clamping member 2” is released, and under the action of the torsion spring, the clamping member 2” returns to its original position and clamps onto the circular end cap-type workpiece 20. At this time, the clamping member 2” presses the circular end cap-type workpiece 20 against the V-shaped clamping part 21, forming a stable clamping of the circular end cap-type workpiece 20. Based on the above operation, multiple circular end cap-type workpieces 20 can be placed on a clamping device for circular end cap-type workpieces. Afterwards, the circular end cap-type workpieces 20 can be driven to undergo an oxidation operation through the clamping device for circular end cap-type workpieces. It is easy to understand that when unloading the circular end cap workpiece 20, it is only necessary to push the clamping member 2” to open the set of clamping parts 21 relative to each other, thus releasing the circular end cap workpiece 20. Therefore, the clamping device for circular end cap workpieces of this application has a simple structure and is easy to perform clamping and unloading operations. The clamping device for circular end cap workpieces can clamp multiple circular end cap workpieces at once, resulting in high work efficiency. This clamping device for circular end cap workpieces is applicable to circular end cap workpieces of different diameters, exhibiting strong versatility and high applicability. This clamping device for circular end cap workpieces has the capability to be linked with automated equipment, enabling automated production and improving work efficiency.
