Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a positioning clamp for measuring different bending radii of planar bent pipes. Background Technology

[0002] In precision manufacturing fields such as automobile manufacturing and pipeline engineering, the bending accuracy of planar pipe bends (such as engine intake and exhaust pipes and hydraulic system oil pipes) directly determines the assembly sealing performance and system operating efficiency. After production, planar pipe bends need to be dimensionally inspected using equipment such as coordinate measuring machines and laser scanners. Positioning fixtures are the core auxiliary devices that ensure measurement accuracy. Their main function is to clamp the bends and ensure the precision of the measurements.

[0003] However, existing clamps for flat pipe bending still have certain drawbacks. For example, the bending radius of flat pipes varies significantly, and traditional positioning clamps are mostly designed for one-to-one use with fixed clamping structure dimensions, which cannot adapt to multiple specifications of pipes, resulting in poor applicability of the clamps. Secondly, the fixed position of the clamps means that they can only clamp specific positions of the flat pipe. Once the position of the flat pipe is changed, it will affect the clamping stability of the clamp at that point. Utility Model Content

[0029] Working principle: During operation, the first motor 2 is activated according to the bending position of the flat bend, driving the rotating shaft 3 to rotate the disc 4 and the first adjusting frame 5, thereby adapting the included angle between the first adjusting frame 5 and the second adjusting frame 6 to the bending position of the flat bend.

Then, the hexagonal rotating block 19 is loosened, driving the threaded column 18 to disengage the anti-slip pad 21 from the connecting plate. 10. Then, the clamping frame 13 is rotated around the connecting shaft 11 as the axis, so that the flat bend can be placed between the two corresponding clamping plates 16 according to the bending direction of the flat bend. At the same time, the hexagonal rotating block 19 is rotated in the opposite direction, which drives the threaded column 18 to drive the contact block 20 and the anti-slip pad 21 to abut against the connecting plate 10, so as to realize the rotation limit of the clamping frame 13, thereby ensuring that the flat bend can be stably placed between the two corresponding clamping plates 16. Then, the turntable 15 is rotated, which drives the bidirectional threaded rod 14 to drive the two corresponding clamping plates 16 to move towards each other, thereby clamping and fixing the flat bend.
