[0024] The utility model will be described in detail in combination with the drawings.

[0025] In order to make the utility model's purpose, technical scheme and advantage more clearly, the following will be further detailed with the drawings and examples. It should be understood that the specific examples described here are only to explain the utility model, and are not used to limit the utility model.

[0026] A divided boring indexing template, as shown in Figures 1-4 the drawing, includes a template body, which is provided with an indexing mark and two sets of connecting hole groups corresponding to two components.

[0027] The divided boring indexing template 1 with high-precision positioning features can provide a unified positioning reference on different components. The divided boring indexing template 1 is installed on the runner body 2 and the operating frame 3 respectively, and the positioning features of the template are accurately aligned with the corresponding machining positions on the components. A numerical control boring machine is used to individually index each component through the divided boring indexing template 1. After indexing is completed, the template and the components are fixed, and then boring machining of shaft holes and ear holes is performed. Since the two components use the same divided boring indexing template 1, the relative position accuracy between them can be ensured. The center or a suitable position of the template body is provided with an indexing mark, and this hole is used to cooperate with the precision indexing device of the numerical control boring machine to ensure the accurate position of the template on the machine tool. Different regions of the template body are provided with two sets of connecting hole groups, and each set of hole groups corresponds to the specific connection and positioning requirements of a component. The layout and size of these hole groups are determined according to the interface design of the two components to ensure that the template can be accurately connected with the components, and the corresponding indexing positions of the two components and the divided boring indexing template 1 are the same indexing mark after they are connected, so as to realize the relative position accuracy of the template and the components. The indexing mark can be an indexing hole 11 or an indexing line 12.

[0028] As another specific embodiment, the outer periphery of the template body is a regular polygon structure. It can be used to ensure the accurate alignment and repeatability of the assembly.

[0029] As another specific embodiment, the indexing mark is an indexing hole 11 and / or an indexing line 12. The indexing hole 11 is used to cooperate with a specific positioning pin of the boring machine to realize accurate positioning. The indexing line 12 provides a visual reference for aligning the machining center line or checking the machining position. Through the indexing hole 11 and / or the indexing line 12, the operator can quickly and accurately set the position of the workpiece, align the boring machine, and ensure the accuracy of the boring machining.

[0030] As another specific embodiment, the alignment holes 11 include four holes arranged in a "cross" shape. The four alignment holes 11 are arranged on two mutually perpendicular axes, forming a layout similar to a "cross". Two holes on one axis are parallel to each other, and two holes on the other axis are also parallel to each other, and the two axes intersect perpendicularly. By aligning the workpiece through the two holes on the diagonal, the accuracy of the alignment is improved.

[0031] As another specific embodiment, the alignment line 12 is an X-Y line engraved on the two end faces and the generatrix of the template body. By engraving the X-Y line on the two end faces and the generatrix, positioning in three dimensions can be achieved, ensuring the correct position of the workpiece in space for initial alignment when machining the runner body 2 and the operating frame 3. The engraving of the X-Y line provides an intuitive visual reference, allowing the operator to quickly and accurately adjust the position of the workpiece.

[0032] As another specific embodiment, the set of connection holes includes a set of runner body 2 connection holes 13 and a set of operating frame 3 connection holes 14. The set of runner body 2 connection holes 13 is used to match the specific structure of the runner body 2, ensuring the accurate position of the runner body 2 on the template. The set of operating frame 3 connection holes 14 is used to match the structure of the operating frame 3, ensuring the correct position of the operating frame 3 on the template. Since the operating frame 3 and the runner body 2 use the same indexing alignment template 1 for partial body boring, the consistency of the machining positioning between the two can be ensured, which is crucial for the overall performance and reliability of the assembly. The two sets of connection holes provide a unified machining standard for the two different components, standardizing the machining process and reducing errors caused by component differences.

[0033] As another specific embodiment, the upper end face of the template body is provided with a first stop 15 corresponding to the stop of the runner body 2; the lower end face of the template body is provided with a second stop 16 corresponding to the stop of the operating frame 3. The first stop 15 matches the stop of the runner body 2, ensuring the accurate docking between the template body and the runner body 2, thereby ensuring the positioning accuracy during machining. The second stop 16 cooperates with the stop of the operating frame 3 to accurately position the operating frame 3, ensuring the correct position of the operating frame 3 on the template body. The design of the stop generally has a certain guiding and error-proofing function, which can prevent the template body from rotating or mispositioning during installation. The stops of the runner body 2 and the operating frame 3 are similar or need to be separated in space, and the design of the stops on the upper end face and the lower end face can avoid interference during assembly.

[0034] As another specific embodiment, the rotating body 2 connecting hole group 13 and the operating frame 3 connecting hole group 14 are respectively arranged on the two end faces of the template body. The rotating body 2 connecting hole group 13 is arranged on one end face of the template body, and the operating frame 3 connecting hole group 14 is arranged on the other end face, so that the connection of each component corresponds to a specific end face of the template body. The connecting hole group of each end face matches the corresponding stop opening (the first stop opening 15 and the second stop opening 16), which ensures the correct position and direction of the component on the template body. Through the corresponding design of the end face and the stop opening, the precise positioning of the rotating body 2 and the operating frame 3 can be realized, thereby improving the assembly accuracy of the whole system.

[0035] As another specific embodiment, a plurality of observation holes 17 are arranged in the middle part of the template body. During assembly and adjustment, the coaxiality of the template and the rotating body 2 and the operating frame 3 can be intuitively checked and adjusted. Among them, when the observation hole 17 is arranged from one end face to the other end face, it does not pass through the opposite stop opening position.

[0036] The use method of the split boring indexing template in the embodiment includes the following steps:

[0037] Step A, processing the rotating body 2:

[0038] A1, the split boring indexing template 1 is mounted on the rotating body 2; the split boring indexing template 1 is accurately installed on the predetermined position of the rotating body 2. The connecting hole group of the template matches the specific interface of the rotating body 2, which ensures the relative position accuracy of the template and the rotating body 2.

[0039] A2, the split boring indexing template 1 is used to align the rotating body 2 with the numerical control boring machine; the accurate position of the rotating body 2 on the machine tool is ensured by aligning the alignment mark of the split boring indexing template 1 with the alignment device of the numerical control boring machine. This process ensures the accuracy of subsequent processing.

[0040] A3, the rotating body 2 is processed by the numerical control boring machine; the rotating body 2 is accurately aligned, and the numerical control boring machine starts to bore the blade shaft hole of the rotating body 2. Due to the positioning effect of the split boring indexing template 1, the position accuracy of the shaft hole is guaranteed.

[0041] Step B, processing the operating frame 3:

[0042] B1, the split boring indexing template 1 is mounted on the operating frame 3; similar to step A1, this step involves installing the split boring indexing template 1 on the predetermined position of the operating frame 3. Another set of connecting hole groups of the template matches the interface of the operating frame 3, which ensures the relative position accuracy of the template and the operating frame 3.

[0043] B2, the degree of the split boring degree of the template 1 is used to find the alignment between the numerical control boring machine and the numerical control boring machine, and the operation frame 3 is aligned; the alignment mark of the degree of the split boring degree of the template 1 is aligned with the alignment device of the numerical control boring machine, and the accurate position of the operation frame 3 on the machine tool is ensured. This process ensures the machining accuracy of the ear hole of the operation frame 3.

[0044] B3, the operation frame 3 is processed by the numerical control boring machine; after the operation frame 3 is accurately aligned, the numerical control boring machine starts to bore the ear hole of the operation frame 3. Because the same degree of the split boring degree of the template 1 is used, the position accuracy of the ear hole of the operation frame 3 matches the position accuracy of the shaft hole of the runner body 2.

[0045] Wherein, the order of steps A and B is not limited. The order of steps A and B can be interchanged, which means that the machining order can be adjusted according to the production plan and resource availability, improving the flexibility of the production process. Each component can be machined independently, reducing the risk of affecting the entire production process due to the delay of one component.

The present application extends to any new features or any new combinations disclosed in the specification, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
