Specifically, the number of the abutting vertical blocks 3 and the number of the follow-up barb locking mechanisms can be four, and the abutting vertical blocks and the follow-up barb locking mechanisms are respectively arranged on the outer sides of four side surfaces of the middle block 2.
Example two
Referring to fig. 4 to 6 in conjunction with fig. 1 to 3, the present embodiment further provides a clamping device for an automobile part, the clamping device for an automobile part provided in the present embodiment is substantially the same as the clamping device for an automobile part provided in the first embodiment, and the difference between the two embodiments is: compared with the clamping device for the automobile parts in the first embodiment, the clamping device for the automobile parts in the present embodiment is additionally provided with the following structures:
as an example, a receiving groove 10 is further provided on a side surface of the fastening vertical block 3 where the follow-up type barb locking mechanism is provided, the receiving groove 10 is communicated with a first end of the hydraulic chamber 13, and a size of the receiving groove 10 matches a size of the stressed plate 8. Specifically, the shape of the receiving groove 10 is completely the same as the shape of the force-bearing plate 8, the size (width or diameter) of the receiving groove 10 is completely the same as the size of the force-bearing plate 8, and the depth of the receiving groove 10 is completely the same as the thickness of the force-bearing plate 8; this ensures that the force-bearing plate 8 is completely accommodated in the accommodating groove 10 when an external force is applied.

By arranging the telescopic part 9 between the middle-arranged block 2 and the abutting vertical block 3, when the stress plate 8 is stressed, the abutting vertical block 3 can move towards the middle-arranged block 2 and recover when external force is eliminated.
Said telescopic means 9 comprise, as an example, a telescopic cylinder or a hydraulic cylinder.
In the clamping device for the automobile parts, a tubular part penetrates through four abutting vertical blocks 3 and is placed on the bottom platform 1, then four telescopic parts 9 are controlled to drive the four abutting vertical blocks 3 to be far away from the middle-arranged block 2, the outer edges of the four abutting vertical blocks 3 gradually abut against the inner wall of the tubular part, in the process that the four abutting vertical blocks 3 abut against the inner wall of the tubular part, four stress plates 8 are gradually pressed to be close to four accommodating grooves 10 outside the four abutting vertical blocks 3, so that the four second connecting blocks 7 respectively drive four first piston blocks 11 in the four hydraulic cavities 13 to extend into the four hydraulic cavities 13, liquid filled in the four hydraulic cavities 13 is pushed to the second ends of the hydraulic cavities, and the four first connecting blocks 15 are respectively pushed out of the hydraulic cavities 13 by four second piston blocks 14, four of the installation clamping seats 6 are driven to move towards one side close to the bottom platform 1 in the installation groove 16, so that the four barbs 4 can fasten the outer edge of the end part of the tubular part.
According to the clamping device for the automobile parts, the four abutting vertical blocks 3 are used for compressing the inner wall of the tubular part, and meanwhile, the four barbs 4 can be used for synchronously fastening the outer edge of the end part of the tubular part through the matching of the hydraulic systems in the four abutting vertical blocks 3, so that the tubular part is not prone to tilting during clamping operation, the clamping of the part in place can be greatly guaranteed, the phenomenon of accidental rotation of the tubular part after stress can be avoided due to the synchronous fastening of the four barbs 4 on the outer edge of the end part of the tubular part, and the assembly efficiency and the assembly effect after clamping are guaranteed.
