[0031] In addition, it should be understood that, for the convenience of description, the sizes of various components shown in the drawings are not drawn in accordance with the actual proportional relationship, for example: the thickness or width of certain layers can be exaggerated relative to other layers.

[0032] It should be noted that similar reference numbers and letters represent similar items in the following drawings, and therefore, once an item is defined or described in one drawing, it will not need to be further specifically discussed and described in the description of subsequent drawings.

[0033] To solve the technical problems in the background art, as shown in Figures 1-6 The present application provides a technical solution: a pipe material shot blasting conveying clamping mechanism, characterized by:

[0034] The fixed seat 1 is the basis of the whole clamping mechanism, which is formed by the top plate 2, the side plate 3 and the bottom plate 4 connected in turn to form a I-shaped structure. This structure design not only provides stable support, but also facilitates the installation and maintenance of other components. The fixed seat 1 is provided with mechanisms for transverse clamping and vertical clamping of the pipe. The V-shaped clamping surface 5 is provided on the bottom plate 4 and is used for preliminary positioning and clamping of the pipe. The V-shaped clamping surface 5 is V-shaped with an included angle of 90 degrees and is symmetrically designed. The screw rod 7 has external threads and is threadedly connected with the internal threaded hole 6 on the top plate 2. One end of the screw rod 7 is provided with a clamping block 8, and the side of the clamping block 8 facing the V-shaped clamping surface 5 is provided with a V-shaped surface 9. The V-shaped clamping surface 5 and the V-shaped surface 9 are coaxial. By rotating the screw rod 7, the position of the clamping block 8 can be adjusted so that it forms a transverse clamping of the pipe together with the V-shaped clamping surface 5. The guide sleeve 11 is a cylindrical sleeve coaxially arranged with the through hole 10 on the top plate 2. One end of the guide sleeve 11 is provided with a fixed block 12, and the fixed block 12 is provided with a center hole 13. The pipe passes through the through hole 10 and enters the guide sleeve 11 to remain vertical. The fixed shaft 15 passes through the center hole 13 in the fixed block 12 and the positioning hole 14 in the side plate 3. One end of the fixed shaft 15 is provided with a fastening nut 16, and the other end is hingedly connected with an eccentric wheel 17. The side wall of the eccentric wheel 17 abuts against the side plate 3, and one side of the eccentric wheel 17 is provided with a handle 18. By rotating the handle 18, the eccentric wheel 17 can be driven to rotate, and the eccentric distance of the eccentric wheel 17 is used to realize the reciprocating motion of the fixed shaft 15, thereby realizing the clamping or releasing of the guide sleeve 11.

[0035] In actual operation, when the pipe needs to be transversely fixed, the pipe is placed on the V-shaped clamping surface 5, which has a centering effect and can automatically ensure that the center line of the pipe is aligned with the axis of symmetry of the V-shaped clamping surface 5. Rotate the screw rod 7 to move the clamping block 8 towards the pipe until the V-shaped surface 9 contacts the pipe and forms a stable clamping. When the pipe needs to be longitudinally fixed, one end of the pipe is inserted into the guide sleeve 11 through the through hole 10 to ensure the correct position of the pipe. Rotate the handle 18 to make the fixed shaft 15 reciprocate through the rotation of the eccentric wheel 17, thereby realizing the clamping of the guide sleeve 11 and ensuring the stability of the pipe during the shot blasting process. After the shot blasting process is completed, the handle 18 is rotated in the opposite direction to release the clamping force of the guide sleeve 11, and the pipe is taken out. Of course, transverse and longitudinal fixation and clamping can be performed simultaneously.

[0036] It should be noted that the guide surface 19 is arranged on the periphery of the through hole 10 of the top plate 2, and the guide surface 19 is designed in a trumpet shape. This design makes the diameter of one end of the guide surface 19 connected to the through hole 10 smaller than the diameter of the other end, thereby forming a gradually expanding entrance, facilitating the introduction and positioning of the pipe. The main function of the guide surface 19 is to provide a smooth guide path before the pipe enters the clamping mechanism. The trumpet-shaped design allows the pipe to be smoothly guided to the correct position even if there is a slight deviation in the initial position, and then accurately clamped by the V-shaped clamping surface 5 and the V-shaped surface 9 of the clamping block 8.

[0037] Further, in order to enhance the structural stability and carrying capacity of the fixed seat 1, the pipe shot blasting conveying clamping mechanism in the embodiment further comprises a reinforcing rib 20. The reinforcing rib 20 connects the side plate 3 and the bottom plate 4, providing additional support and stability to the entire clamping mechanism. The main function of the reinforcing rib 20 is to improve the structural strength and rigidity of the fixed seat 1, especially when clamping heavy pipes, the reinforcing rib 20 can effectively prevent deformation or damage at the connection between the side plate 3 and the bottom plate 4.

[0038] It should be noted that the limiting rod 21 is arranged on the side plate 3 and in contact with the side wall of the guide sleeve 11, providing additional positioning and limiting function for the pipe. The main function of the limiting rod 21 is to prevent excessive movement or rotation of the pipe during clamping and conveying, ensuring that the pipe always remains in the predetermined position and posture.

[0039] Further, the fixed block 12 is designed in a cylindrical sleeve structure, which not only enhances the stability of the structure, but also provides a flexible layout scheme for the guide sleeve 11. Along the side wall of the fixed block 12, multiple guide sleeves 11 are arranged. The fixed block 12, as a key component for carrying and positioning the guide sleeve 11, provides uniform support force through its cylindrical sleeve structure, ensuring the stability and durability of the guide sleeve 11. The arrangement of multiple guide sleeves 11 allows the clamping mechanism to improve utilization, as one guide sleeve 11 can be replaced with another when it is worn out.

[0040] It should be noted that in order to further enhance the adaptability and flexibility of the pipe shot blasting conveying clamping mechanism, multiple guide sleeves 11 are specially designed, which have different inner diameters. This design allows the same clamping mechanism to adapt to pipes of different diameters, thereby improving the versatility and economic benefits of the equipment. The inner diameter of each guide sleeve 11 is designed according to the common pipe diameter specifications, ensuring that the pipe can be tightly fitted to avoid shaking during shot blasting.

[0041] Notably, in order to enhance the positioning accuracy and stability of the pipe during the shot blasting process, a stop surface 22 is specially provided inside the guide sleeve 11. The design of the stop surface 22 is an innovation of our organization, which provides additional limiting and supporting for the pipe, ensuring that the pipe does not move axially or radially during high-speed shot blasting. When the pipe is placed in the guide sleeve 11, the stop surface 22 contacts the end of the pipe to provide stable support.

[0042] It should be noted that the operating handle 23 is sleeved on one end of the screw rod 7 and is cross-shaped. The main function of the operating handle 23 is to provide an easy-to-hold and operate interface, so that the operator can adjust the position of the screw rod 7 by rotating the handle, thereby realizing the clamping or releasing of the pipe. This design makes it more convenient and comfortable for the operator to clamp and release the pipe. When clamping or releasing the pipe is needed, the operator only needs to hold the operating handle 23 and rotate it to drive the screw rod 7 to move forward or backward. By rotating the operating handle 23, the screw rod 7 drives the clamping block 8 to move towards the V-shaped clamping surface 5, realizing the clamping of the pipe; reversing the rotation can release the pipe. The cross-shaped design of the operating handle 23 makes the operator more stable when exerting force, reducing the risk of hand slipping or misoperation during operation.

[0043] It is worth mentioning that the gasket 24 is sleeved on the fixed shaft 15 and abuts against the side plate 3 and the eccentric wheel 17 on both sides. This design plays a key role in buffering and positioning. The main function of the gasket 24 is to reduce the direct contact between the fixed shaft 15 and the side plate 3 and the eccentric wheel 17, thereby reducing wear and noise, while providing certain elastic buffering, enhancing the stability and durability of the entire mechanism. The gasket 24 can be made of wear-resistant materials such as polytetrafluoroethylene PTFE, nylon or other engineering plastics to ensure its wear resistance and stability in long-term use.

[0044] Although embodiments of the present application have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and alterations can be made thereto without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
