Description

Technical Field

[0001] The utility model belongs to the field of workpiece processing equipment, in particular to a hexagonal workpiece wire cutting processing fixture. Background Art

[0002] Hexagonal workpieces refer to workpieces with a hexagonal shape. Workpieces of this shape are very common in mechanical processing. Common hexagonal workpieces include worm gears, hexagonal nuts, etc. The characteristics of hexagonal workpieces are that the six sides are equal and the six angles are 120 degrees. Therefore, they have good positioning and fixing performance and are widely used in mechanical assembly. Hexagonal workpieces are widely used in mechanical processing, especially in occasions where positioning and fixing are required. For example, when assembling machines, hexagonal nuts can be used as connectors. By screwing them into threaded holes, machine parts can be fixed and connected. In addition, when manufacturing precision mechanical parts, hexagonal workpieces can also be used as reference surfaces to ensure the accuracy of the size and position of the parts.

[0003] In the process of cutting hexagonal workpieces, cylindrical blanks are usually cut. When the cylindrical blanks are clamped by a fixture, it is easy for the cylindrical blanks to be non-concentric with the inscribed circle of the hexagonal workpiece to be cut, resulting in the shape and size of the cut hexagonal workpiece being inconsistent with the shape and size required to be cut, which affects the processing of the hexagonal workpiece.

After the column blank is extruded, the wire cutting machine 101 can be started, and the first threaded rod 4 can be controlled to rotate, so that the first threaded rod 4 cooperates with the thread of the sliding seat 5, driving the sliding seat 5 to move to the position corresponding to the wire cutting machine 101. After the sliding seat 5 passes through the wire cutting machine 101, the extrusion rotating block 11 can be controlled to rotate 60°, thereby driving the cylindrical blank to rotate 60°, and controlling the first threaded rod 4 to rotate in the opposite direction, driving the cylindrical blank to move in the opposite direction. This reciprocating process is repeated three times to complete the cutting of the six sides of the hexagonal workpiece, thereby making it more convenient to cut the hexagonal workpiece.

[0025] like Figure 1 As shown, the sliding rail 3 is slidably connected to the top position of the cutting body 1; an electric push rod is fixedly connected to the side wall of the cutting body 1, and a push-pull rod 12 is fixedly connected to the output end of the electric push rod; the end of the push-pull rod 12 is fixedly connected to the side wall of the sliding rail 3; during operation, when the hexagonal workpiece is cut, the push-pull rod 12 can be driven to slide by the electric push rod, thereby driving the sliding rail 3 to slide, and the position of the sliding rail 3 can be adjusted, and the distance between the sliding seat 5 and the wire cutting machine 101 can be adjusted, so that the size of the processed hexagonal workpiece can be adjusted, making the processing of the hexagonal workpiece more convenient.

[0028] like Figure 5 As shown, a positioning block 16 is fixedly connected to the side wall of the first threaded rod 4; the positioning block 16 is rotatably connected to the internal position of the sliding rail 3; during operation, when the first threaded rod 4 rotates inside the sliding rail 3, by arranging the positioning block 16 on the side wall of the first threaded rod 4, the first threaded rod 4 can be less likely to tilt during rotation, thereby making the rotation of the first threaded rod 4 more stable.

[0029] like Figure 5As shown, a plurality of balls 17 are provided between the sliding rail 3 and the positioning block 16; the side walls of the balls 17 are in contact with the side walls of the sliding rail 3 and the positioning block 16; during operation, when the positioning block 16 rotates inside the sliding rail 3, by providing the balls 17 between the sliding rail 3 and the positioning block 16, the sliding friction between the sliding rail 3 and the positioning block 16 can be converted into rolling friction, so that the friction force between the sliding rail 3 and the positioning block 16 is smaller, thereby reducing the wear between the sliding rail 3 and the positioning block 16.

[0030] During operation, when it is necessary to cut the hexagonal workpiece, the cylindrical blank can be placed on the top of the sliding seat 5, and the second threaded rod 7 can be controlled to rotate so that the push guide block 6 cooperates with the thread of the second threaded rod 7, and the cylindrical blank is extruded and pushed through the guide groove 601, so that the cylindrical blank can stay at a position concentric with the extrusion rotating block 11, and then the third threaded rod 9 can be controlled to rotate so that the third threaded rod 9 cooperates with the thread of the push plate 10, driving the push plate 10 to descend, and the cylindrical blank is extruded through the extrusion rotating block 11. Afterwards, the wire cutting machine 101 can be started, and the first threaded rod 4 can be controlled to rotate, so that the first threaded rod 4 cooperates with the thread of the sliding seat 5, driving the sliding seat 5 to move to the position corresponding to the wire cutting machine 101.

[0032] When the cylindrical blank is pushed by the extrusion rotating block 11 and driven to rotate, by arranging the driven block 13 inside the sliding seat 5, when the cylindrical blank rotates, the driven block 13 can rotate together with the cylindrical blank, thereby making the friction between the cylindrical blank and the sliding seat 5 smaller, making it more stable when the extrusion rotating block 11 drives the cylindrical blank to rotate, and at the same time, setting the guide groove 601 inside the pushing guide block 6 can make the friction between the cylindrical blank and the pushing guide block 6 smaller, thereby making it more stable when driving the cylindrical blank.

[0033] When the push plate 10 slides inside the third threaded rod 9 , the positioning rod 15 is provided to limit the sliding of the push plate 10 , so that the push plate 10 can be more stable when sliding.

[0034] When the first threaded rod 4 rotates inside the sliding rail 3, by providing a positioning block 16 on the side wall of the first threaded rod 4, the first threaded rod 4 can be less likely to tilt during rotation, thereby making the rotation of the first threaded rod 4 more stable.

[0035] When the positioning block 16 rotates inside the sliding rail 3, by arranging the ball 17 between the sliding rail 3 and the positioning block 16, the sliding friction between the sliding rail 3 and the positioning block 16 can be converted into rolling friction, so that the friction force between the sliding rail 3 and the positioning block 16 is smaller, thereby reducing the wear between the sliding rail 3 and the positioning block 16.
