Detailed Description
In order to make the structure and function of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention.
Referring to the attached drawings 1-2, the fixture for the broaching machine comprises a broaching tool 3 and a sliding block device 5 which are arranged on the broaching machine, wherein a linear guide rail 4 is arranged on the broaching machine, the direction of the linear guide rail 4 is consistent with the processing direction of the broaching tool 3, the sliding block device 5 is in sliding connection with the linear guide rail 4, and the tail part of the broaching tool 3 is connected with the sliding block device 5 and drives the sliding block device 5 to slide along the linear guide rail 4. The broaching machine is provided with a clamping fixture for fixing the retainer, and the center position of the broaching tool is consistent with that of the retainer.
Based on the technical scheme, the sliding block device 5 moves along with the broaching tool 3, and plays a role in balancing weight stability for the tail part of the broaching tool, so that the tail part of the broaching tool is positioned without swinging during machining, and the sliding block device 5 is arranged on the fixed linear guide rail 4, so that the stability of the main motion of linear broaching is ensured.
Further, the section of the linear guide rail 4 is of an i-shaped structure. The I-shaped structure has upper and lower limit, and prevents the slide block device 5 from moving up and down and vibrating.
Further, the slider device comprises a slider body 8, the lower portion of the slider body 8 is matched with the linear guide rail 4, the upper portion of the slider body 8 is provided with a cavity, V-shaped iron 10 is arranged in the cavity, and the tail portion of the broach 3 is placed on the V-shaped iron 10 and fastened through a fastening bolt 9.
Based on the technical scheme, the size of the V-shaped iron 10 is matched with that of the cavity, so that the V-shaped iron 10 is prevented from moving in the cavity and affecting the positioning effect of the tail of the broach.
