Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making creative efforts belong to the protection scope of the present invention.
The present invention will be described in further detail with reference to examples and specific embodiments.
Examples are given.
As shown in fig. 1, 2, 3 and 4, a small punch pin finish milling tool comprises a tool main body 1, a pressing plate block 2 and a pressing bolt 3; the top of the tool main body 1 is transversely provided with two cylindrical mounting holes 4, the middle of the tool main body 1 is longitudinally provided with a long strip-shaped through hole 5, and the bottoms of the two cylindrical mounting holes 4 are communicated with the long strip-shaped through hole 5; the pressing plate block 2 is of a two-section strip-shaped structure, the two sections 2 are respectively inserted into two sides of the strip-shaped through hole 5, a pressing screw hole is formed between the two sections, and the bottom of the cylindrical mounting hole 4 is covered by the pressing plate block 2; the center of the top of the tool main body between the tops of the two cylindrical mounting holes 4 is provided with a vertical downward pressing screw hole 6, the pressing screw hole 6 penetrates through the lower part of the strip-shaped through hole 5, the pressing bolt 3 is arranged on the upper part of the pressing screw hole 6, and the bottom of the pressing bolt 3 can press the pressing plate block 2 below the pressing screw hole 6 towards the lower part of the pressing screw hole after being screwed downwards.
The top of the cylindrical mounting hole 4 is transversely provided with a strip-shaped opening 7 along the top of the tool main body 1, an arc-shaped adjusting plate 8 is further arranged below the strip-shaped opening 7 and above the cylindrical mounting hole 4, and an adjusting bolt 9 is arranged at the top of the arc-shaped adjusting plate 8. Just so can satisfy the fixed demand of clamping that the drift was waited to process to different specifications, to the less cylindrical mounting hole 4 of packing into of the drift that waits to process of diameter, only need screw up adjusting bolt 9 and push up arc adjusting plate 8 downwards and make the lower surface of arc adjusting plate 8 and the top surface in close contact with who waits to process the drift can.
Meanwhile, a strip-shaped notch 10 is transversely formed in the middle of the top of the tool main body 1, the compression bolt 3 is an inner hexagon bolt, and the compression screw hole 6 is formed in the middle of the strip-shaped notch 10. Therefore, when the compression bolt 3 is screwed into the compression screw hole 6, the nut of the compression bolt 3 can be hidden in the strip-shaped notch 10, so that the looseness caused by processing vibration is not easy to occur, and the attractiveness of the tool main body 1 cannot be influenced by the fact that the nut protrudes out of the top surface of the tool main body.
The two end portions of the pressing plate block 2 are vertically bent to form retaining ends 21. The middle of the side faces of the two longitudinal ends of the tool main body 1 are provided with hidden notches 11, the anti-falling ends 21 are hidden in the hidden notches, and gaps are reserved between the inner side faces of the anti-falling ends and the bottoms of the hidden notches. Therefore, the pressing plate block 2 can move back and forth and upwarp in the strip-shaped through hole 5 and cannot fall off from the strip-shaped through hole when the pressing bolt 3 is screwed in and pressed down.
In this example, the utility model discloses the theory of operation of little drift finish milling pin frock as follows: when the punch 12 to be processed needs finish milling, the punch is inserted into the cylindrical mounting hole 4, then the adjusting bolt 9 is screwed down to press the arc-shaped adjusting plate 8, so that the lower surface of the arc-shaped adjusting plate 8 is tightly contacted with the top surface of the punch 12 to be processed, then the pressing bolt 3 is screwed down into the pressing screw hole 6, the inner sides of the pressing plate blocks 2 at the two sides of the pressing bolt 3 are pressed towards the lower part of the pressing screw hole 6 by the screw thread of the pressing bolt 3, at the moment, the edge of the pressing screw hole 6 in the long strip-shaped through hole 5 is used as a fulcrum, so that the pressing plate block 2 at the bottom of the cylindrical mounting hole 4 is driven to upwarp and is upwards extruded from the bottom surface of the punch 12 to be processed, and the punch 12 to be processed is clamped in the cylindrical mounting hole 4 to be firmly fixed. Therefore, the punch 12 to be machined can be clamped easily when placed in the tool with the arc-shaped characteristic, the pressing plate block 2 is stressed to press the punch 12 to be machined by screwing the pressing bolt 3, and the punch 12 is effectively machined and measured after machining.
