Description

Technical Field

[0001] The present invention belongs to the field of mechanical processing technology. It is a fixture design for modular processing of collaborative CNC equipment. It is a clamping device for four-axis processing of strip sheets by CNC equipment. It can be used for precise and complex special-shaped structural parts with complex and compact structures, strong dimensional correlation, dispersed processing procedures, and the formation of a multi-dimensional processing system. Background Art

[0002] The processing of complex and diverse precision and special-shaped structural parts presents numerous challenges. These components feature thin-walled cavities, stepped steps, narrow slots, deep holes, circular arcs, and threads. These components require numerous machining elements, with closely interconnected and mutually influential geometric dimensions, resulting in a multi-dimensional machining precision system. Traditional machining methods involve fragmented processes, difficult positioning and clamping, inconsistent datums, and poor structural rigidity. These methods are prone to deformation or displacement, making it difficult to maintain the original geometric shape and stability. This makes it impossible to guarantee machining accuracy and product quality, and results in long production cycles and high processing costs.

[0003] To ensure effective control of geometric dimensions during machining, in-depth research into the clamping of complex structural parts is required to ensure machining accuracy. The main factors affecting the machining accuracy of complex and special-shaped structural parts can be summarized as follows: the close geometric relationship between the various dimensions of complex and special-shaped structural parts requires a complex dimensional chain to control accuracy; the inclusion of multiple machining surfaces, hole systems, and irregular shapes requires multiple machining steps and is difficult to arrange; and the lack of uniformity between design and process datums requires frequent datum conversions during machining, increasing the risk of error accumulation.

[0004] Therefore, in response to the above situation, a fixture for modular processing of collaborative CNC equipment was designed and manufactured. The fixture has a simple structure, is light and fast to operate, and has good practicality and versatility. Summary of the Invention

[0005] The purpose of the present invention is to provide a processing fixture for products with complex special-shaped structures, which realizes multi-faceted processing by one clamping through the cooperation of numerical control equipment and four-axis linkage processing, thereby improving the physical quality of the product and production efficiency. The fixture is characterized in that: the fixture consists of a clamp body (1) and a locking screw (2). A numerical control dividing head is connected to a three-jaw chuck to clamp the clamp body (1), and the locking screw (2) locks the blank through the threaded holes in the Y direction and the Z direction on the clamp body (1), thereby realizing modular processing.

[0006] This fixture transforms traditional discrete processing into an integrated one, resolving the challenges of machining complex, irregularly shaped parts with strong dimensional correlations, complex structures, and multi-faceted machining. Part deformation is particularly effectively controlled, improving machining accuracy and product quality. Furthermore, the fixture, in conjunction with four-axis CNC equipment, can replace the basic functions of a five-axis machining center, reducing equipment purchase costs. Furthermore, consideration is given to operational convenience, practicality, and structural versatility, resulting in a more efficient and stable machining process.

[0010] The present invention provides a fixture for modular processing of collaborative numerical control equipment. Figure 1 In the schematic diagram shown, the blank material is passed through the clamp body (1), set to a suitable processing position, and then the locking screw (2) is tightened with an inner hexagonal wrench to fix the blank material before processing.

[0011] This fixture effectively solves the problem of processing complex and special-shaped structural parts caused by factors such as complex structure, close dimensional correlation, and poor processing technology. The specifications of the part blank can be flexibly adjusted according to the standard parameters of the four-axis CNC equipment. It has good practicality and structural versatility, improves processing accuracy and production efficiency, and greatly reduces production costs.
