[0002] At present, in the process of processing products, the positioning end face of the workpiece is not absolutely perpendicular to the broaching tool, which will lead to unqualified keyway symmetry after keyway drawing, and the keyway mouth is prone to collapse, resulting in poor appearance. This tooling uses a movable spherical support to automatically align the workpiece during the broaching process, always maintaining the perpendicularity with the broaching tool, effectively solving the previous problems. Summary of the invention

[0003] In view of this, the present invention aims to propose an automatic alignment broaching machine tool, which realizes automatic alignment with a spherical elastic matching structure that can be automatically adjusted, so that after the keyway is processed, the symmetry and appearance of the keyway are good.

[0004] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0005] An automatic alignment broaching machine tool comprises a connecting plate, a spherical movable support and a fixed plate. One end of the connecting plate is connected and installed with the broaching machine, a spherical groove is arranged in the middle of one end, and the fixed plate is fixedly connected to the outer side. One end of the spherical movable support is provided with a spherical portion that slides with the spherical groove, and one end is provided with an L-shaped ring groove for installing a gear. A U-shaped ring groove is arranged in the middle of the spherical support, and one end of the fixed plate close to the spherical movable support is arranged in the groove. The inner sides of the connecting plate and the spherical movable support are provided with through and equal-sized broaching tool holes.

[0006] Furthermore, the fixing plate is semicircular, and two fixing plates are provided. The inner ring of the semicircular plate is arranged in the U-shaped ring groove, and the inner ring and both side surfaces of the semicircular plate have a certain adjustment space with the inner surface of the U-shaped ring groove.

[0007] Furthermore, a semi-annular boss is arranged inward from the outer edge on one side of the fixing plate close to the connecting disk, the inner ring position of the annular boss cannot exceed the spherical groove, the end face of the boss away from the fixing plate is fitted with the connecting disk, and the fixing plate is provided with a screw through hole for connecting the fixing plate and the connecting disk at the position where the boss is arranged.

[0008] Furthermore, one end of the spherical portion of the spherical movable support close to the fixed plate and one end of the connecting plate close to the fixed plate may be on the same plane;

[0009] The spherical portion of the spherical movable support has a cylindrical groove vertically formed at one end close to the fixed plate, a spring and a push pin are fixed in the cylindrical groove, one end of the spring is fixed to the bottom of the cylindrical groove, and the other end is fixed to the push pin, an end of the push pin away from the spring abuts against the fixed plate, and the abutting position is arranged at one end of the fixed plate close to the spherical groove and located on the inner side of the boss.

[0010] Furthermore, a cylinder is vertically fixed to one end of the spherical portion of the spherical movable support close to the fixed plate, a ring is vertically fixed to the middle of the cylinder, a U-shaped ring groove for setting the fixed plate is formed between the ring and the spherical portion, and an L-shaped ring groove for installing the gear is formed with the cylinder on the side of the ring away from the fixed plate.

[0011] Furthermore, a small plane 1 is arranged at one end of the spherical portion of the spherical movable support away from the fixed plate, a small plane 2 is arranged at one end of the spherical groove away from the fixed plate, and a certain adjustment space is arranged between the small plane 1 and the small plane 2.

[0013] The connecting disk described in the present invention is connected to the broaching machine, and the fixing plate is connected to the connecting disk by screws. The fixing plate limits the position of the spherical movable support by a spring and a push pin. The connecting disk and the spherical support are in contact through the spherical surface, and relative sliding can occur. In the process of broaching the keyway, the workpiece is subjected to the axial clamping force of the broach, and the end face rests on the outer end face of the circular ring of the spherical movable support. The spherical surfaces slide relative to each other, so that the end face of the spherical movable support and the end face of the workpiece always remain perpendicular to the broach. After the keyway is completed, the symmetry and appearance of the keyway are good. BRIEF DESCRIPTION OF THE DRAWINGS
