[0001] The present application relates to the technical field of parts processing, and in particular to a tooling fixture for processing precision parts of die-casting molds. Background Art

[0002] Fixtures and fixtures are process equipment used to position and clamp workpieces in the field of mechanical processing. Their core function is to ensure that the workpiece maintains a stable posture under cutting force, thermal deformation and other working conditions through precise geometric constraints and reliable mechanical clamping, thereby ensuring processing accuracy and efficiency.

[0003] In the processing of precision parts of die-casting molds (such as cores, cavities, sliders, etc.), workpieces often need to be precisely processed on multiple sides and angles to meet complex surface and high precision requirements. In the workpiece processing system, the coordinate system is generally established with the length direction of the workpiece as the X-axis and the height direction of the workpiece as the Y-axis. The existing tooling and fixtures have the following defects: Most tooling and fixtures adopt a fixed positioning structure. After the workpiece is clamped, it cannot move along the X-axis and Y-axis, and cannot rotate around the X-axis, which cannot meet the multi-faceted and multi-angle processing needs of the workpiece.

[0004] Therefore, a tooling fixture for processing precision parts of die-casting molds is needed to solve the problem that the existing tooling fixtures have insufficient flexibility in angle adjustment. Summary of the invention

[0005] In order to achieve rapid and high-precision adjustment of the angle of a workpiece, the present application provides a tooling fixture for processing precision accessories of a die-casting mold.

[0007] By adopting the above technical scheme, the clamping assembly can place and stably clamp the workpiece, the placement groove on the clamping seat enables the workpiece to slide along the axial direction of the workpiece, the clamping assembly can adjust the clamping position to accommodate workpieces of different sizes, the clamping seat and the rotating disk slide together, so that the workpiece can move along the radial direction of the rotating disk, and the rotating assembly drives the clamping assembly to rotate, thereby realizing the self-rotation of the workpiece. Compared with the existing technology, the tooling fixture can quickly and accurately adjust the position of the workpiece to meet the needs of multi-faceted and multi-angle processing of the workpiece.

[0009] By adopting the above technical solution, the sliding member can slide on the clamping seat to adjust its position, thereby realizing the position adjustment of the first locking member. The clamping position of the workpiece can be adjusted to adapt to workpieces of different sizes, thereby enhancing the applicability of the tooling fixture. After the first locking member is threadedly connected to the first locking hole, it interferes with the workpiece, thereby ensuring the stability of the workpiece during the processing.

[0010] Optionally, the clamping seat is provided with a long slide groove extending along the length direction of the workpiece, and the sliding member is provided with a protruding block that slidably cooperates with the long slide groove.

[0011] By adopting the above technical solution, the protrusion and the long slide groove are slidably matched to achieve stable sliding of the sliding member on the clamping seat along the length direction of the workpiece, thereby improving the position accuracy and stability when the workpiece is fixed and enhancing the versatility of the tooling fixture.

[0012] Optionally, a plurality of the long sliding grooves are arranged along the radial direction of the rotating disk, and one of the long sliding grooves is slidably matched with the protrusion.

[0014] Optionally, the rotating disk is provided with a radial groove extending radially along the rotating disk, the end of the clamping seat is provided with a sliding block slidably matched with the radial groove, the clamping seat is provided with a second locking hole set through, the second locking hole is threadedly connected with a second locking piece, and the second locking piece passes through the sliding block and contacts with the inner wall of the radial groove.

[0015] By adopting the above technical solution, the radial slide groove arranged on the rotating disk cooperates with the slider at the end of the clamping seat, so that the clamping seat can slide and adjust along the radial direction of the rotating disk, adjust the position of the workpiece to meet the processing requirements of the workpiece, and the second locking member passes through the slider and contacts the inner wall of the radial slide groove, so that the clamping seat can be firmly locked after the position of the clamping seat is adjusted, thereby preventing the clamping seat from being offset after the rotating disk rotates, thereby ensuring the stability of the workpiece during the processing.

[0016] Optionally, a limiting ridge is protruding from the inner side of the radial sliding groove and extending radially along the rotating disk, and a limiting groove is formed on the sliding block to cooperate with the limiting ridge.

[0017] By adopting the above technical solution, the limiting cooperation between the limiting ridge and the limiting groove makes the sliding between the slider and the radial slide groove precisely constrained along the length direction of the workpiece, ensuring that the sliding of the clamping seat in the radial slide groove is smoother, and effectively preventing the slider and the clamping seat from deviating during operation, thereby improving the overall stability of the tooling fixture.

[0021] By adopting the above technical scheme, the locking assembly cooperates with the long hole on the base to realize flexible control of the rotation state of the rotating disk. When the rotating disk needs to be fixed, the sliding cooperation between the protrusion and the first slide groove enables the resistance rod to firmly resist the rotating disk, preventing the rotating disk from rotating accidentally and ensuring stable processing of the workpiece. When it is necessary to contact the rotating disk to lock in order to adjust the angle of the workpiece, the resistance rod is rotated to allow the protrusion to enter the second slide groove, which improves the operating convenience of the tooling fixture and enhances the stability and safety during the processing.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. The clamping assembly can place and stably clamp the workpiece.
