Description

Technical Field

[0001] This invention relates to the field of Alpha winding machines, specifically to an Alpha winding mechanism applicable to multiple product names. Background Technology

[0002] Alpha winding machines are widely used for the automatic winding of various coils, bobbins or cores. The commonly used core structure is a fixed central shaft with upper and lower blades: the upper blade is usually an integral disc, and the lower blade is an integral ring or a piece. They are fixed to the central shaft with screws to form a clamping circle. The clamping diameter depends on the blade size and the central shaft diameter. It is usually a special structure for a single product name.

[0003] However, these specialized mechanisms have poor versatility. When it is necessary to switch to workpieces with different inner diameters or heights, it is often necessary to replace the entire mechanism or multiple parts. The changeover process is cumbersome and time-consuming, and multiple mechanisms must be stocked, which increases costs and management burden. If adjustment is made solely by screws in the round holes, there are problems such as poor coaxiality, unstable positioning, and limited adjustment range. It can also easily cause damage to the workpiece surface. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art, adapt to practical needs, and provide an Alpha winding mechanism applicable to multiple product names. This addresses the problem that current dedicated mechanisms have poor versatility. When it is necessary to switch to workpieces with different inner diameters or heights, it is often necessary to replace the entire mechanism or multiple parts. The changeover process is cumbersome and time-consuming, and multiple sets of mechanisms must be kept in stock, increasing costs and management burden. If adjustment is made solely by screws in round holes, there are problems such as poor coaxiality, unstable positioning, and limited adjustment range. It is also easy to cause damage to the workpiece surface.

[0005] To achieve the objective of this invention, the technical solution adopted is as follows: An Alpha winding mechanism suitable for multiple product names is designed, comprising a central shaft, an upper blade, and a lower blade. The upper blade is disc-shaped and has guide slots evenly distributed along the radial direction. The lower blade consists of an annular fixed seat and several movable lower blades. The movable lower blades are equidistantly arranged on the circumference and correspond to the guide slots. Fasteners pass through the guide slots and connect to the central shaft. The upper blade and the movable lower blades together form a clamping circle for clamping the workpiece.

[0006] Preferably, the movable lower blade has four blades, with concentric arcs on the inner edge and fan-shaped arcs on the outer edge.

[0007] Preferably, the guide slot is an elongated hole, which is used to cooperate with the movable lower blade to form a sliding structure under guidance and constraint.

[0008] Preferably, the fastener is a wing nut.

[0009] Preferably, the central axis is detachable and switchable to achieve rapid switching within the range of 20 to 27.6 mm.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] 1. This invention enables rapid adjustment of the effective clamping diameter on a single movement, with the central shaft covering a diameter range of 20 to 27.6 mm. This shortens changeover time, reduces the number of movement reserves, improves positioning accuracy, and lowers the risk of workpiece damage, thereby enabling continuous production of multiple product names.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: An Alpha winding mechanism applicable to multiple product names, see [link to example]. Figures 1 to 7 It includes a central shaft 1, an upper blade 2 and a lower blade. The upper blade 2 is disc-shaped and has guide grooves 6 evenly distributed along the radial direction. The lower blade consists of an annular fixed seat 5 and several movable lower blades 4. The movable lower blades 4 are equidistantly arranged on the circumference and correspond to the guide grooves 6. Fasteners pass through the guide grooves 6 and are connected to the central shaft 1. The upper blade 2 and the movable lower blades 4 together form a clamping circle for clamping the workpiece.

[0022] The central shaft 1 is installed as a reference in the transmission part of the winding machine. The upper blade 2 is fixed on the central shaft 1 and serves as an adjustment and positioning structure. The lower blade consists of an annular fixed seat 5 and several movable lower blades 4.

[0023] For details, see Figure 3 The movable lower blade 4 consists of four blades, with concentric arcs on the inner edge and fan-shaped arcs on the outer edge.

[0024] Further, see Figure 5 The guide slot 6 is an elongated hole, which is matched with the movable lower blade 4 to form a sliding structure that is guided and constrained.

[0025] The operator first moves the movable lower blade 4 radially within the guide groove 6 according to the inner diameter of the workpiece to be wound. During the adjustment process, the guide groove 6 cooperates with the lower blade. When the movable lower blade 4 is adjusted to the required diameter position, the lower blade is locked to complete the clamping of the workpiece.

[0026] It is worth noting that, see Figure 1 The fastener is a wing nut 3.

[0027] It is worth noting that, see Figure 6 The central axis 1 is detachable and switchable, allowing for rapid switching within the range of 20 to 27.6 mm.

[0028] If it is necessary to switch between workpieces of different diameter ranges, simply replace or adjust the central shaft sleeve 1 to quickly switch within the range of 20 to 27.6 mm without replacing the entire mechanism.

[0029] When using the Alpha winding mechanism applicable to multiple product names, the central shaft 1 is installed as a reference in the transmission part of the winding machine. The upper blade 2 is fixed on the central shaft 1 and serves as an adjustment and positioning structure. The lower blade consists of an annular fixed seat 5 and several movable lower blades 4. The operator first slides the movable lower blades 4 radially in the guide groove 6 according to the inner diameter of the workpiece to be wound. During the adjustment process, the guide groove 6 cooperates with the lower blades. When the movable lower blades 4 are adjusted to the required diameter position, the lower blades are locked to complete the clamping of the workpiece. If it is necessary to switch workpieces with different diameter ranges, it is only necessary to replace or adjust the sleeve of the central shaft 1 to quickly achieve switching within the range of 20 to 27.6 mm without replacing the entire mechanism.

[0030] In addition, all components designed in this invention are general standard parts or components known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this invention does not involve improvements to the internal structure and method.
