Description

Technical Field

[0001] The utility model relates to the technical field of casting processing, in particular to a stable cutting device positioning mechanism. Background Art

[0002] Investment casting is a common metal casting process used to manufacture complex-shaped, high-precision metal parts. The die set refers to the mold or pattern used to form the investment pattern, and its design and manufacture are critical to the quality and performance of the final product.

[0003] The structure of investment casting molds is complex and changeable. The mold cutting operation is arduous and labor-intensive. Horizontal moving cutting is often performed using an X-axis with a fixture. The X-axis is manually controlled to move horizontally to the cutting piece. After cutting, it is necessary to constantly stop and adjust the fixed angle of the mold before cutting to ensure the cutting effect.

[0004] When the existing X-axis walking structure fixes the module, the cutting position is adjusted on one side of the cutting device. Since the position adjustment is done manually by workers, it is easy to cause a certain deviation in the cutting position after the module is fixed on the X-axis, thereby reducing the accuracy of controlling the incision position, resulting in a large amount of gate residue and the grinding wheel scratching the casting. Utility Model Content

[0005] The purpose of the utility model is to provide a stable cutting device positioning mechanism to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a stable cutting device positioning mechanism, comprising: a workbench, an X-axis walking structure, a Z-axis walking structure and a Y-axis walking structure; the X-axis walking structure is arranged at the bottom of the workbench, the Z-axis walking structure is arranged at one side of the X-axis walking structure, the Z-axis walking structure includes a connecting head welded on one side of the X-axis walking structure, a first screw rod rotatably connected to the top of the connecting head rotates to drive a first nut seat with a threaded connection to move up and down; the Y-axis walking structure is arranged at one side of the first nut seat, the Y-axis walking structure includes a connecting plate connected to one side of the first nut seat by bolts, a second screw rod rotatably connected to one side of the connecting plate rotates to drive a second nut seat with a threaded connection to move horizontally.

[0007] By adopting the above technical solution, by adding a Z-axis walking structure to the X-axis walking structure, and installing a Y-axis walking structure on the Z-axis walking structure, the device can drive the module to move on the Y-axis and Z-axis during cutting, and the positions of the Y-axis and Z-axis can be adjusted after cutting a position, so as to achieve the effect of adjusting the position of the module at any time, and determine the cutting position before cutting, thereby improving the effect of controlling the accuracy of the incision position.
