Description
Technical Field
[0001] This application relates to the technical field of processing of asymmetric clamping blocks, and particularly relates to a tooling for opening holes in an asymmetric clamping block. Background Art
[0002] In modern industrial production, tooling fixtures, as an indispensable part of the machining process, directly affect the machining accuracy, production efficiency, and cost of workpieces. With the continuous development of the manufacturing industry, the requirements for tooling fixtures are getting higher and higher. Especially when dealing with workpieces with asymmetric features, traditional symmetric fixtures often fail to meet the machining requirements. Therefore, developing a tooling for opening holes in an asymmetric clamping block has important practical significance and application value.
[0003] Traditional tooling fixture design is mainly based on the symmetry principle. This design shows good stability and reliability when dealing with workpieces with symmetric features. However, for workpieces with asymmetric features, such as some special-shaped parts or components, traditional symmetric fixtures often fail to provide sufficient clamping force and stability, resulting in deviations or quality problems during the machining process.
[0004] Therefore, when traditional tooling fixtures clamp asymmetric workpieces, complex adjustment and positioning operations are often required, which not only increases the labor intensity of workers but also reduces production efficiency. At the same time, due to unstable clamping, the workpiece may move or deform during the machining process, further affecting the machining quality. Summary of the Utility Model
[0005] The purpose of this application is to solve the problem that traditional tooling fixtures often require complex adjustment and positioning operations when clamping asymmetric workpieces, which reduces production efficiency and affects the stability of the workpiece during the machining process.

One end of the L-shaped base is provided with a driving chute, and a driving slider is slidably connected inside the driving chute. The top of the driving slider is fixedly connected with an L-shaped fixing table. One end of the L-shaped fixing table is symmetrically and fixedly connected with partition blocks. One end of the L-shaped fixing table is symmetrically provided with slots, and a prefabricated clamping block is inserted into the slots. A driving screw is rotatably connected inside the driving chute, the driving slider is threadedly connected with the driving screw, one end of the driving screw passes through the L-shaped base and is fixedly connected with a driving handle, and a processing through-hole is provided at one end of the L-shaped base.
[0008] By adopting the above technical solution, through the combined use of the partition block, the slot, and the prefabricated clamping block, after the two prefabricated clamping blocks are driven to drive the workpiece to be processed into the interior of the slot, by rotating the driving screw rod, the L-shaped fixing table is driven to push the workpiece to be processed to form a fixed contact with the L-shaped base, so as to facilitate the fixation of the workpiece through the processing holes and processing through holes opened on the surface of the prefabricated clamping block, thereby facilitating the rapid fixation and clamping of the workpiece to be processed, improving the stability of the device processing, and reducing the labor intensity of the staff.

[0016] By adopting the above technical solution, through the combined use of the driving chute and the chip discharge port three, the chips remaining in the slot pass through the chip discharge port three and the driving chute and fall into the interior of the collection tank, facilitating the rapid discharge of the chips remaining in the slot and effectively improving the practicability of the device.
[0017] Further, a scale is provided at the bottom of the collection tank, one end of the L-shaped base is fixedly connected with an indicating mark adapted to the scale, and an adjusting assembly is installed at the bottom of the L-shaped base.
[0018] By adopting the above technical solution, through the combined use of the adjusting assembly, the scale and the indicating mark, it is convenient to drive the L-shaped base to drive the indicating mark to rotate by rotating the adjusting assembly, and cooperate with the scale to drive the L-shaped base to rotate to the required angle, thereby further improving the practicability of the device.
[0019] Further, the adjusting assembly includes a bevel gear one fixedly connected to the bottom of the L-shaped base, a bevel gear two meshing with the bevel gear one is rotatably connected inside the L-shaped base, and one end of the bevel gear two passes through the L-shaped base and is fixedly connected with a knob.
