[0034] Please refer to Figures 1 to 11 , this application provides a grooving auxiliary tool for assisting in processing installation grooves for installing hinges on frames such as doors and windows.

[0035] Combined with Figure 11 As shown, the installation groove is opened on frames such as door frames and window frames, and it includes a first-stage groove and a second-stage groove from inside to outside to correspondingly place the body and the installation part of the concealed hinge.

[0036] Specifically, combined with Figure 1 As shown, in an embodiment, the grooving auxiliary tool includes a first auxiliary part for assisting in processing the first-stage groove and a second auxiliary part for assisting in processing the second-stage groove.

[0037] Among them, the first auxiliary part is provided with a first-shaped hole penetrating from the upper surface to the lower surface, and the first-shaped hole is used for assisting in processing the first-stage groove; the second auxiliary part is provided with a second-shaped hole penetrating from the upper surface to the lower surface, and the second-shaped hole is used for assisting in processing the second-stage groove. A positioning part is downwardly extended from the lower surface of the second auxiliary part, and the positioning part is adapted to the first-stage groove and is used for positioning the second auxiliary part in the first-stage groove.

[0038] The main function of the first auxiliary part is to assist in processing the first-stage groove on the door frame, and it is provided with a first-shaped hole of a strip-shaped through hole penetrating through it. The first-shaped hole serves as a guide for processing tools (such as milling cutters or grooving machines) to ensure that the required first-stage groove can be accurately processed on the frame.

[0039] For more stable placement, the lower surface of the first auxiliary part is a flat surface to better fit the surface of the frame.

[0040] The second auxiliary part is mainly used to assist in processing the second-stage groove on the basis of the first-stage groove. Similar to the first auxiliary part, a second-shaped hole is penetratingly provided on the second auxiliary part, and the second-shaped hole serves as a guide for processing the second-stage groove.

[0041] In this application, one of the core designs of the second auxiliary part is the positioning part downwardly extended from its lower surface. The positioning part is adapted to the first-stage groove and can accurately snap the second auxiliary part into the first-stage groove. Through the design of the positioning part, the second auxiliary part can be stably fixed in the first-stage groove, avoiding processing errors caused by improper manual positioning. In addition, the design of the positioning part enables the second auxiliary part to be quickly and accurately positioned, greatly reducing the time for adjustment and calibration, thereby improving the processing efficiency.

[0042] Combined with Figures 2 to 4 As shown, in this embodiment, the first type of hole in the first auxiliary part is a strip-shaped through hole. The structural design of the strip-shaped through hole can be adapted to the main body structure of the current conventional concealed hinge.

[0043] In other embodiments, according to the main body structure of the concealed hinge main body, different forms of the first type of hole can be adaptively designed.

[0044] Combined with Figure 2 and Figure 4 As shown, in order to enhance the stability of the first auxiliary part during the processing, in this embodiment, the first auxiliary part is provided with a plurality of limiting holes for passing through fasteners such as screws and bolts from the upper surface to the lower surface.

[0045] The first auxiliary part is firmly fixed on the frame through fasteners, thereby preventing the first auxiliary part from shifting or loosening during the processing. This design not only improves the processing accuracy, but also significantly enhances the stability and safety of the operation.

[0046] Specifically, in order to improve the fixing effect, a plurality of limiting holes can be provided, and the limiting holes are arranged on both sides of the first type of hole.

[0047] Combined with Figure 2 As shown, in this embodiment, the limiting holes are set to 4, and two limiting holes are arranged on each side of the first type of hole, which can not only improve the fixing stability, but also, when processing the second-level groove subsequently, the fasteners can be drilled into the residual holes formed in the frame and removed together by hollowing out, so that the frame will not leave the residual holes formed by processing.

[0048] In other embodiments, the limiting holes can also be set to two, three or more, which can also play a role in restricting the position of the first auxiliary part.

[0049] Combined with Figures 2 to 4 As shown, in this embodiment, a limiting part for aligning with the edge of the frame is downwardly extended on the outer side of the lower surface of the first auxiliary part.

[0050] The limiting part is used to align with the edge of the frame to ensure the accurate processing position of the first type of hole. The limiting part can keep the first auxiliary part always in a state parallel to the edge of the door frame, effectively avoiding the deviation caused by manual operation. Through this design, the operator can greatly simplify the measurement steps, reduce the positioning error, and significantly improve the work efficiency.

[0051] Combined with Figures 2 to 4 As shown, in order to further improve the consistency of the processing depth of the first-level groove, the first auxiliary part is provided with a first depth-determining part, and the first depth-determining part protrudes from the surface of the first auxiliary part.

[0052] Specifically, the first fixed depth part can be prominently arranged on the side surface of the first auxiliary part. The distance between the first fixed depth part and the outer side end face is set according to the required machining depth of the first-stage groove, so that the first fixed depth part can be used as a reference for the machining depth positioning of machining tools such as milling cutters. During operation, the tool tip of the machining tool can be pushed into the first fixed depth part from the outer side of the first auxiliary part, and the machining depth of the first-stage groove can be determined according to the locked pushing-in depth.

[0053] In this embodiment, multiple first fixed depth parts can be provided. According to different hinge product specifications, the positions of the first fixed depth parts (i.e., the distances from their outer ends of the first auxiliary part) can be set to be the same or different.

[0054] Combined with Figure 4 As shown, in order to make the whole more lightweight, the inside of the first auxiliary part can be set as a cavity structure, and at the same time, rib plates are used to connect and strengthen components such as the limit hole and the first type hole to ensure the structural strength.

[0055] Combined with Figure 5 As shown, in this embodiment, two second type holes are provided, and the second type holes are symmetrically arranged at both ends of the second auxiliary part. Through the design of the two symmetric second type holes, when machining the second-stage groove, the complete machining of the second-stage groove can be realized without moving the second auxiliary part.

[0056] Combined with Figure 6 As shown, in another embodiment, one second type hole is provided, and the second type hole is arranged at one end of the second auxiliary part. Through the design of a single second type hole, when machining the second-stage groove, first machine one part of the groove through the second type hole, and then turn the position of the second auxiliary part to symmetrically machine the other part of the groove, thereby completing the entire machining of the second-stage groove.

[0057] Combined with Figure 5 、 Figure 7 As shown, the second auxiliary part is provided with a second fixed depth part, and the second fixed depth part is prominently arranged on the surface of the second auxiliary part.

[0058] Referring to the above description of the design principle of the first fixed depth part, the second fixed depth part is used to assist in determining the machining depth of the machining tool for the second-stage groove.

[0059] In this embodiment, multiple second fixed depth parts can also be provided. According to different hinge product specifications, the positions of the second fixed depth parts (i.e., the distances from their outer ends of the second auxiliary part) can be set to be the same or different.

[0060] Combined with Figure 8As shown, in order to ensure that the machining tool has sufficient movement space during the machining process and is not affected by interference from the second auxiliary part, a clearance groove is provided on the side of the positioning part facing the second hole. This clearance groove is a concave design, which can effectively avoid interference from tools or materials during the machining process, ensuring the smoothness and integrity of the entire machining process.

[0061] Combined with Figure 7 As shown, in order to make the whole more lightweight, the interior of the second auxiliary part can be set as a cavity structure, and at the same time, reinforcing ribs are provided to ensure the structural strength.

[0062] Combined with Figures 9 to 11 As shown, the usage method of the grooving auxiliary tool in this application is as follows:

[0063] First, align the first auxiliary part with the edge of the frame through the limiting part, and drill fasteners such as screws into the frame through the limiting holes to fasten the first auxiliary part to the frame.

[0064] Then, a milling cutter or grooving machine can be used to machine the first-stage groove through the first hole. Due to the guiding function of the first hole and the depth control of the depth setting part, the machined first-stage groove has an accurate shape and depth.

[0065] Next, remove the first auxiliary part, insert the positioning part of the second auxiliary part into the machined first-stage groove, and achieve stable positioning of the second auxiliary part through the precise engagement of the positioning part; then, the first-stage groove can be further machined through the second hole to form a second-stage groove. When machining the second-stage groove, half of the residual hole of the fastener drilled into the frame can be removed.

[0066] The guiding function of the second hole ensures the accuracy of the machining position, while the design of the clearance groove ensures the smoothness of the machining process and the safety of the tool.

[0067] Through the above steps, the machining of the installation groove structure for the concealed hinge on the frame can be completed quickly and accurately, ensuring the installation effect of the hinge.

[0068] The above has introduced the grooving auxiliary tool provided by the embodiment of this application in detail, and specific embodiments are used to explain the principle and implementation method of this application. The above description is only used to help understand the method and its core mechanism of this application; at the same time, for those of ordinary skill in the art, according to the idea of this application, there will be changes in specific embodiments and application scopes. In summary, the content of this specification should not be construed as a limitation to this application.
