Description

Technical Field

[0001] The utility model relates to the technical field of servo mechanism assembly, in particular to a servo mechanism assembly punching device. Background Art

[0002] A two-axis rotary servo mechanism typically consists of an outer frame spindle, an inner frame, and a pitch frame. While the outer frame spindle drives the inner frame's rotation, the pitch frame within the inner frame can also rotate about its axis. During drilling and assembly, the servo mechanism workpiece must be adjusted to a specific position, secured, and then holes drilled on the back of the pitch frame. This requires extremely high positioning accuracy for the servo mechanism workpiece, as it rotates flexibly and freely in a free state, making it difficult to secure. Failure to pay attention to the inner frame's orientation during drilling can result in holes being drilled in the wrong direction.

[0003] The existing technology uses caulking and gluing to fix the position of the servo mechanism, which is unstable and has low precision. There is also the possibility of reverse drilling of the holes, and excess materials will remain inside the product.

[0004] Therefore, there is an urgent need to design a special tooling to punch holes in the workpiece of the two-axis rotary servo mechanism and ensure the accurate punching position. Utility Model Content

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] In the description of the utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," "the other end," and the like, indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of the utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] In the description of the utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0038] See also Figure 1-8 The utility model provides a technical solution: a servo mechanism assembly punching device, including a tooling base 1 and a servo mechanism component 4.

[0039] A first positioning groove 11 and a second positioning groove 12 are formed on the top of the tooling base 1 . The first positioning groove 11 is connected to the anti-error support frame 2 , and the second positioning groove 12 is connected to the angle positioning frame 3 .

[0040] Recessed mounting grooves 21 are provided on both sides of the anti-error support frame 2, and a first mounting hole 22 is provided through the bottom of the recessed mounting groove 21. The first mounting hole 22 is connected to the tooling base 1 through a first bolt 23 through a threaded structure, and an intermediate anti-deviation groove 24 is provided on the top of the anti-error support frame 2. Two groups of supports 26 are fixedly connected in the intermediate anti-deviation groove 24, and a card slot 27 is provided between the two groups of supports 26.

[0041] Specifically, since the structures on both sides of the pitch frame 43 are different, in order to avoid drilling the wrong holes, a slot 27 is provided for embedding the protrusion connected to the pitch frame 43, and the two sets of supports 26 support the pitch frame 43, providing stability while allowing the drilling drill bit to extend into the inner side of the slot 27 during processing, thereby reserving processing space for the drill bit and avoiding damage to the device.

[0042] The width of the anti-error support frame 2 is adapted to the width of the first positioning slot 11. Figure 2 And the instruction manual Figure 5By setting the first positioning groove 11, it is ensured that the anti-error support frame 2 can be accurately positioned on the tooling base 1 during installation. The design of adaptive width enables the first positioning groove 11 to have a positioning effect on the anti-error support frame 2, and it can be more firmly fixed on the tooling base 1 after installation, avoiding the position displacement of the servo mechanism component 4 due to the loosening of the support frame during the punching process, thereby ensuring the stability and accuracy of the punching.

[0043] The top sides of the anti-error support frame 2 are provided with contour fitting grooves 25, and two groups of contour fitting grooves 25 are respectively provided on both sides of the middle anti-deviation groove 24, and the two sides of the inner frame 42 are respectively adapted to be connected to the two groups of contour fitting grooves 25. Figure 3 And the instruction manual Figure 5 The design of the contoured fitting groove 25 enables the anti-error support frame 2 to better fit the shape of the servo mechanism component 4 during installation, ensuring that the components can fit tightly during the installation process, avoiding positioning errors caused by loose fitting, and improving the accuracy of punching. In addition, the contoured fitting groove 25 can effectively support and fix the inner frame 42, preventing deformation and position displacement caused by uneven force during the punching process.

[0044] A second mounting hole 31 is formed through the lower end of the angle positioning frame 3. A second bolt 32 is threadedly connected to the tooling base 1. A spindle hole 33 is formed through the upper end of the angle positioning frame 3. Specifically, the angle positioning frame 3 enables the servo mechanism 4 to maintain a desired angle.

[0045] The width of the angle positioning frame 3 is adapted to the width of the second positioning slot 12, and the angle positioning frame 3 is an "L" shaped structure. Figure 4-5 The width of the angle positioning frame 3 is adapted to the width of the second positioning groove 12, ensuring that the angle positioning frame 3 can be accurately positioned on the tooling base during installation, avoiding positioning errors caused by size mismatch, and improving the positioning accuracy of the overall device. The width-adaptive design enables the angle positioning frame 3 to be more firmly fixed on the tooling base 1 after installation.

[0046] Specifically, the angle positioning frame 3 is designed to be an oblique "L" shape, and the angle of the servo mechanism component 4 when punching is determined by the oblique angle. A vertical incision is designed at the sharp corner of the angle positioning frame 3, so that the angle positioning frame 3 can perform the punching operation in the second direction alone. At the same time, the hollow design on both sides of the main shaft hole 33 can facilitate subsequent balancing operations, and the servo mechanism component 4 can be suspended to prevent it from rolling directly on the desktop and damaging the wiring harness.

[0047] The servo mechanism component 4 includes an outer frame spindle 41, an inner frame 42 and a pitch frame 43. The outer frame spindle 41 is fixedly connected to the inner frame 42, and the pitch frame 43 is rotatably connected to the inner side of the inner frame 42. The outer frame spindle 41 is inserted into the spindle hole 33, and the pitch frame 43 is connected to the middle anti-deflection groove 24. One side of the pitch frame 43 is connected to the card slot 27.

[0048] For details, please refer to the attached manual. Figure 1 And the instruction manual Figure 4 Several groups of pin holes are opened on the outer frame main shaft 41, and several groups of pin holes in corresponding positions are opened near the main shaft hole 33 of the angle positioning frame 3. During installation, the pins can be inserted into the pin holes on the inner side of the angle positioning frame 3 and the outer frame main shaft 41, thereby avoiding the rotation of the outer frame main shaft 41, and the circumferential positioning is accurate, and the inner diameter length of the main shaft hole 33 is adapted to the outer diameter length of the lower end of the outer frame main shaft 41.

[0049] One side of the tooling base 1 is designed with an inclined surface. The inclined surface of the tooling base 1 is on the same inclined surface as the bottom of the error-proofing support frame 2, and the inclined surface of the tooling base 1 is perpendicular to the upper end of the angle positioning frame 3. Specifically, the inclined surface design allows the tooling base 1 to remain stable on the work surface after rotating to a certain angle. Figure 5-7 The inclined surface design enables the tooling base 1 to be tilted, thereby completing the punching operation in two directions in one clamping, simplifying the operation process and improving work efficiency.

[0050] The middle anti-deflection groove 24 is parallel to the bottom surface of the tooling base 1. Specifically, the top surface of the support platform 26 is parallel to the bottom surface of the tooling base 1. Figure 7-8 When the bottom of the tooling base 1 is placed on the work surface, the pitch frame 43 can be punched in the first punching direction. Figure 6 After the entire device is tilted at a certain angle so that the inclined surface on the left side of the tooling base 1 is placed on the work surface, the pitch frame 43 can be punched in the second punching direction.

[0051] Specifically, when in use, first use the first bolt 23 to fix the anti-error support frame 2 to the first positioning groove 11 on the tooling base plate 1, ensuring that all installation surfaces are flat, and then the servo mechanism component 4 is positioned and installed on the angle positioning frame 3 through the pin hole, and the servo mechanism component 4 and the angle positioning frame 3 are fixed together with the second bolt 32 to the second positioning groove 12 on the tooling base 1, and at the same time, the pitch frame 43 and the inner frame 42 are leaned against the anti-error support frame 2, so that the two sides of the pitch frame 43 are respectively connected to the two groups of contoured fitting grooves 25, and the inner frame 42 is connected to the two groups of supports 26 and the card slots 27. After being fixed and stabilized, ensuring that all mating surfaces are tight, the punching operation in the first punching direction can be started. After the punching is completed, the entire device is tilted so that the left inclined surface is flush with the work table. After fixing it with a vise, the punching operation in the second punching direction can be carried out, and the operation in two directions can be completed with one clamping.

[0052] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
