DETAILED DESCRIPTION
[0014] like Figure 1As shown, a chain outer section correction fixture comprises a first correction fixture body 1 and a second correction fixture body 2. The first correction fixture body 1 is in a vertical direction, the upper end of the second correction fixture body 2 is in a vertical structure with the first correction fixture body 1 in contact with the upper end of the second correction fixture body 2, and the lower end of the second correction fixture body 2 is an inclined structure inclined toward the right side. When in use, it can have a reliable activity space, and can be used to carry out active cooperation through the fulcrum using the lever principle, so as to achieve correction, which is more labor-saving during use. The rear sides of the first correction fixture body 1 and the second correction fixture body 2 are respectively connected to the outer section calibration fixture plate 3 in the horizontal direction through the fastening combination hole 4. The second correction fixture body 2 can rotate relative to the outer section calibration fixture plate 3, and the connection position is used as the active fulcrum for rotational cooperation during activity. The front side of the outer section calibration fixture plate 3 is located on the right side of the second correction fixture body 2 and is provided with two standard pitch matching calibration holes 5. After correction, inspection can be carried out through this position to ensure the position accuracy between adjacent pin shafts. The front of the first correction fixture body 1 and the second correction fixture body 2 is provided with a cylindrical inner eight adjustment hole 6 at the upper end, and the front of the first correction fixture body 1 and the second correction fixture body 2 is provided with an outer eight adjustment hole 7 at the lower position of the outer section calibration fixture plate 3, which can align and match different deformations. The lower end of the first correction fixture body 1 and the second correction fixture body 2 is provided with an outer section correction fixture operating handle 9, and a spring steel wire 8 is connected between the two outer section correction fixture operating handles 9, and the straightening operation is performed by hand when in use. It adopts a brand-new structural design, the overall structure is simple, and the production and use costs are relatively low. When in use, the two pins on the outer sections of the adjacent chains can be corrected, and the calibration test after correction can be performed through the standard hole spacing set on the main structure. It has stronger flexibility in use, higher position accuracy between the pins, and can ensure better safety and more reliable stability of the chain in later use, which can effectively extend the service life of the chain.
[0015] Preferably, the inclination angle of the second correction fixture body 2 with respect to the vertical direction is less than 45 degrees. If the angle is too large, it will affect the operator's holding and require the operator to use it with both hands, which will reduce the convenience during use.
[0016] Preferably, the outer section correction fixture operating handle 9 is connected to the first correction fixture body 1 and the second correction fixture body 2 in a detachable manner, and this structure can be replaced as needed, which is more convenient in production and use.
[0017] Preferably, the left end face of the first correction fixture body 1 and the left end face of the outer section calibration fixture plate 3 are on the same plane, so that the flatness of the outer structure is better and has a better avoidance effect when in use.
