[0022] like Figures 1-6 As shown, a pipe bending detection fixture includes a base 1. The upper surface of the base 1 is provided with a first locking block 2, a second locking block 3, and a third locking block 4 of equal height. There are two first locking blocks 2, all arranged on a virtual straight line 8. The base 1 is provided with two coordinate movers. The execution end of one coordinate mover is connected to the second locking block 3 via a rotator, and the execution end of the other coordinate mover is connected to the third locking block 4 via a rotator. Each first locking block 2 has a first locking groove 5 on its upper surface. The length lines of all first locking grooves 5 are parallel to the virtual straight line 8. The first locking grooves 5 on the two first locking blocks 2 are coaxial and penetrate two opposite sidewalls of the first locking block 1. The upper surfaces of the second locking block 3 and the third locking block 4 are respectively provided with a second locking groove 6 and a third locking groove 7. The two ends of the second locking groove 6 penetrate two opposite sidewalls of the second locking block 3, and the two ends of the third locking groove 7 penetrate two opposite sidewalls of the third locking block 4. The rotation axis of the rotator is perpendicular to the upper surface of the base 1.

[0023] In this embodiment, during use, the position of the third clamping block 4 and the second clamping block 3 relative to the overall structure formed by the two first clamping blocks 2 is adjusted using a coordinate mover, based on the required bending angle of the pipe fitting 19 to be detected. The angles between the length lines of the second clamping slot 6 and the third clamping slot 7 and the virtual straight line 8 are also adjusted. After adjustment, the worker places the manufactured pipe fitting 19 into the first clamping slot 5, the second clamping slot 6, and the third clamping slot 7, observing whether the pipe fitting 19 can be simultaneously placed into these slots. If it can, the pipe fitting 19 is qualified; otherwise, it is unqualified. This detection method reduces the difficulty of detection and does not require a high level of worker education, thus saving manufacturing costs from a labor perspective. Furthermore, the first clamping slot 5, the second clamping slot 6, and the third clamping slot 7 can simultaneously detect the first angle 20 and the second angle 21 on the pipe fitting 19 (e.g., ...). Figure 1 The pipe fitting 19 shown illustrates a first angle 20 and a second angle 21, meaning that a worker's action can detect two angles, thus increasing detection efficiency and consequently improving production efficiency.

After such arrangement, since the two coordinate movers are located on the two sides of the whole formed by the two first clamping blocks 2, collision or interference of the two coordinate movers during adjustment is avoided, thereby reducing the range of the pipe 19 that can be detected by the present application.

[0025] As a preferred mode, the coordinate mover comprises a linear mover X and a linear mover Y, the linear mover Y is arranged on the execution end of the linear mover X, the execution end of the linear mover Y is the execution end of the whole coordinate mover, the moving direction of the linear mover X driving the linear mover Y is parallel to the upper surface of the base 1, the moving direction of the linear mover Y driving the rotator is parallel to the upper surface of the base 1, and the moving direction of the linear mover X driving the linear mover Y is perpendicular to the moving direction of the linear mover Y driving the rotator. After such arrangement, the linear mover X drives the linear mover Y to adjust the position of the first clamping block 2 or the second clamping block 3 on the X axis in the upper surface of the base 1, the linear mover Y drives the rotator to move to adjust the position of the first clamping block 2 or the second clamping block 3 on the Y axis in the upper surface of the base 1, and the rotation of the rotator is used to adjust the angle relationship between the length line of the second clamping groove 6 or the third clamping groove 7 and the virtual straight line 8.

[0026] As a preferred mode, the linear mover X comprises a first motor 9, a lead screw 10 and a sliding block 11, the first motor 9 is fixed on the base 1, the output shaft of the first motor 9 is coaxially connected with the lead screw 10, the lead screw 10 is parallel to the upper surface of the base 1, the sliding block 11 is slidingly connected on the base 1, a screw hole is arranged on the sliding block 11 and threadedly connected with the two ends of the lead screw 10, and the linear mover Y is fixedly arranged on the sliding block 11. After such arrangement, the first motor 9 drives the lead screw 10 to rotate, so that the sliding block 11 moves along the axial direction of the lead screw 10, thereby adjusting the position of the second clamping block 3 or the third clamping block 4 on the X axis in the upper surface of the base 1. Preferably, the sliding block 11 is in the shape of a block, that is, a cuboid, a sliding groove with the same width as the width of the cuboid is arranged on the upper surface of the base 1, and then the lead screw 10 and the sliding block 11 are installed in the sliding groove, and the length line of the lead screw 10 is parallel to the length line of the sliding groove, so that the sliding connection between the sliding block 11 and the base 1 is achieved.

[0027] In a preferred embodiment, the linear actuator Y includes a cylinder 12, which is fixedly mounted on the slider 11. The piston rod of the cylinder 12 is perpendicular to the direction in which the linear actuator X drives the cylinder 12 to move, and the piston rod is parallel to the upper surface of the base 1. The free end of the piston rod is fixedly connected to the rotator. With this configuration, the position of the second locking block 3 or the third locking block 4 on the Y-axis within the upper surface of the base 1 can be adjusted by controlling the length of the cylinder 12.

[0028] In a preferred embodiment, the rotator is a second motor 14, and the output shaft of the second motor 14 is the rotation shaft of the rotator.

[0029] As a preferred embodiment, since some fittings 19 also have a third angle 22, and the plane containing the third angle 22 is perpendicular to the base 1, this application also includes a fourth locking block 15. A section of a crossbar 17 is fixedly connected to the side of the third locking block 15 away from the integral formed by the two first locking blocks 2. A vertical rod 18 is vertically arranged at the other end of the crossbar 17. The fourth locking block 15 is arranged on the side of the vertical rod 18 facing the third locking block 4.
