Description

TECHNICAL FIELD

[0001] The utility model relates to spring processing technical field more specifically, the utility model relates to a kind of cutter position adjusting mechanism of multifunctional special-shaped spring processing equipment. BACKGROUND

[0002] Spring processing equipment is the core equipment for realizing the accurate forming of spring shape and size, and its performance directly determines the quality and production efficiency of spring products. In the field of special-shaped spring processing, the equipment needs to complete complex operations such as bending, cutting and forming of wire through the tool system, and as a core component, the function design of the tool position adjusting mechanism needs to meet the needs of multi-dimensional motion control, high-precision positioning and multi-tool collaborative work. Taking a typical numerical control spring processing equipment as an example, it usually integrates a feeding mechanism, a forming die and a tool adjusting system, and through the driving of a servo motor, the tool moves along a linear guide rail to realize the step-by-step processing of spring wire. For conventional types such as spiral springs and conical springs, existing equipment can complete standardized production through preset programs, but when facing special-shaped structures such as variable-pitch springs and space-bending springs, the limitations of equipment performance gradually become apparent.

[0003] However, the tool adjusting mechanism of existing equipment generally adopts the mode of "multiple tools fixed installation + overall straight movement", which can only realize the synchronous movement of the tool set along a single axis (such as X-axis or Y-axis), and cannot independently adjust the position of a single tool in multiple directions. For example, when processing a composite spring with variable-diameter spiral segments and vertical bending segments, different tools need to work in a horizontal cutting and vertical cutting manner, but the traditional mechanism lacks the ability to control the X / Y / Z axis linkage of a single tool, so it can only complete rough positioning through overall movement of the tool holder, which causes deviations in the processing trajectories of adjacent tools and increases the scrap rate. In addition, for non-symmetrical structures such as oval cross-section springs, the equipment cannot drive the tool to perform linkage interpolation motion along the oval trajectory, but can only approximate it through segmented straight lines, which causes the roughness of the processed surface to deteriorate, and additional polishing processes are needed, reducing production efficiency.

[0004] Secondly, when dealing with multi-process processing tasks, existing equipment is prone to mechanical interference and loss of processing accuracy due to fixed tool position or limited adjustment range. For example, when processing a multi-layer nested special-shaped spring, the installation distance between the inner tool and the outer tool needs to be dynamically adjusted according to the inner diameter of the spring, but the traditional fixed tool holder cannot change the tool distance in real time, which increases the risk of tool collision.
