The ends of telescopic rod A and telescopic rod B have enlarged suction cups; one ends of at least two resisting mold rods are hinged together, and are hinged together at the corner of the right-angle frame, and the other ends conflict with the chamfering steel mold.

The telescopic rod A and the telescopic rod B have the same structure, the telescopic rod A and the telescopic rod B both include a sleeve, a strut and a locking bolt; each sleeve has a built-in strut, and the strut is passed through the locking bolt lock tight.

There is a mounting slot at the intersection of the right-angle frame, and one end of the resisting rod is hingedly installed in the mounting slot.

The end surface of the end contacting with the chamfering steel mold on the mold ejector rod is spherical.

Described resisting mold bar has two, and one end of two resisting mold bars is hinged together, and is hinged together at the corner of right-angle frame, and the other end conflicts with chamfering steel mold.

Compared with the prior art, the utility model has the following beneficial technical effects:

(1) The right-angle frame supports and fixes the entire tooling, and the resisting rod plays a role in positioning the chamfering steel mold. The combination of the two secures the chamfering steel plate firmly; and the resisting rod has two pieces that can simultaneously hold both sides of the chamfering steel mold , the positioning is firm;

(2) The telescopic rod is telescopic, and the strut extends and retracts in the sleeve, and is tightened with bolts, which can adapt to chamfering steel molds of different sizes and inclination angles;

(3) The resisting rod is set in the installation slot in the right-angle frame, the positioning is firm, and the force on the right-angle frame is in the same plane, and the stability is good;

(4) The spherical end of the mold rod is convenient for conflicting with different chamfered steel plates.

detailed description

The utility model will be further described in detail below in conjunction with specific embodiments, which are explanations of the utility model rather than limitations.

Referring to Fig. 1 to Fig. 3, a station floor and side wall chamfering steel mold positioning tool includes a right-angle frame, and the right-angle frame is formed by intersecting the telescopic rod A 3 and the telescopic rod B 4 through the intersection angle, and the intersection angle is a right angle, and the telescopic rod A 3 and telescopic rod B 4 ends have enlarged sucker 34; Arresting rod 2 has two, and one end of two resisting rods 2 is hinged together, and is hinged at the intersection of right-angle frame together, and the other end and chamfering steel mold 1 conflicts.

The right-angle frame supports and fixes the entire tooling, and the resisting rod 2 plays a role in positioning the chamfering steel mold 1. The combination of the two fixes the chamfering steel mold 1 firmly; Resist and position securely.

As a technical optimization scheme of the present utility model, the telescopic rod A3 and the telescopic rod B4 have the same structure, consisting of a sleeve 32, a strut 31 built in the sleeve 32, and a locking pin perpendicular to the side of the sleeve 32. The locking bolt 33 of strut 31 is formed.

As a technical optimization solution of the utility model, there is a mounting slot 5 at the corner of the right-angle frame, and one end of the resisting rod 2 is hingedly installed in the mounting slot 5 . The telescopic rod is telescopic, and the strut 31 stretches out and retracts in the sleeve 32, and is tightened with the locking bolt 33, which can adapt to the chamfering steel mold 1 of different sizes and inclination angles.

As a technical optimization solution of the present invention, the end surface of the resisting rod 2 which is in contact with the chamfered steel mold 1 is spherical. The spherical end of the resisting mold rod 2 is convenient for conflicting with different chamfering steel molds 1 .

When the utility model is in use, the right-angle frame is erected on the chamfering steel mold 1, the telescopic rod A3 is in contact with the side wall, the telescopic rod B4 is in contact with the bottom plate, and the spherical ends of the resisting mold rod 2 are respectively in contact with both sides of the chamfering steel mold 2.
