[0024] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0025] Example 1:
[0026] This embodiment 1 provides a fixing fixture 1, which is used as a fixing tool for the processing of drone blades 2. The drone blades 2 adopt the conventional structure in the current drone technology field, so the brief description is as follows: Please refer to the attached Figure 1 As shown, the UAV blade 2 is provided with a hub 20 and blades 21 connected to the hub 20, wherein the hub 20 is used to connect with the motor drive mechanism in the UAV, that is, it can be understood that a plurality of mounting holes 22 are provided on the hub 20; the blades 21 can be configured to be no less than two and connected to the hub 20 at intervals according to product design requirements; when the motor drive mechanism drives the hub 20 to rotate, the blades 21 can be driven to rotate together.
[0027] Based on the above structure of the drone blade 2, the structure of the fixing fixture 1 preferably used in this embodiment 1 is: Figure 2 As shown, the fixing fixture 1 includes a base plate 10, and a limiting seat 11 and a clamping assembly respectively arranged on the base plate 10, wherein the limiting seat 11 can accommodate and limit the hub 20, the number of the clamping assemblies configured is consistent with the number of the blades 21, and is arranged at intervals on the periphery of the limiting seat 11 according to the arrangement of the blades 21, and each of the clamping assemblies can clamp and limit at least two different parts on the blade 21 corresponding to it. It can be understood that this embodiment 1 can achieve firm support / support and fixation of the drone blade 2 by adopting the limiting seat 11 and a combination of no less than two groups of the clamping assemblies (see the attached Figure 5 As shown in the figure), the machining accuracy and quality of the UAV blades can be effectively improved, which satisfies the production requirements.
[0028] The specific structure of the fixing fixture 1 described in this embodiment 1 is described in detail below.
[0029] First, regarding the limiting seat 11.
[0030] In order to realize the above-mentioned "support / support and fixation" function of the limit seat 11 and combine it with the hub 20 structure, the structure of the limit seat 11 preferably adopted in this embodiment 1 is: Figure 2 and attached Figure 3 As shown, the limiting seat 11 is provided with a receiving groove 110 that matches the shape of the hub 20 and can accommodate the hub 20, and a positioning member 111 that is provided in the receiving groove 110 and can limit the positioning of the hub 20. It can be understood that the receiving groove 110 is a contoured groove structure, which can not only accommodate the hub 20 but also limit the hub 20; when combined with the limiting effect of the positioning member 111 on the hub 20, the hub 20 can be securely positioned in the receiving groove 110. Please refer to the attached figure. Figure 5 shown.
[0031] Furthermore, the positioning member 111 is a positioning pin that can be inserted into the mounting hole 22 on the hub 20. By combining the positioning pin with the mounting hole 22 to achieve the restricted positioning of the hub 20, the operation is simple and convenient, the positioning effect is good, and the structure is simple and the production cost is low.
[0032] In addition, the positioning pin can be fixedly arranged on the inner wall of the bottom of the receiving groove 110 by tight fitting or screw connection, which is a conventional technical means and will not be described in detail here.
[0033] For further information, please refer to the attached Figure 3 As shown, the receiving groove 110 is also integrally provided with a penetration opening 112, and the penetration opening 112 corresponds to the blade 21 one by one, so that the blade 21 can pass through freely. Figure 1 The drone blade 2 shown is provided with two blades 21 that are arranged opposite to each other, and the penetration openings 112 are also provided with two blades that are arranged opposite to each other.
[0034] Next, regarding the clamping assembly.
[0035] Based on the above configuration of the blades 21 , in this embodiment 1, the clamping components are also configured in two groups and are respectively disposed on opposite sides of the limiting seat 11 to cooperate with the two blades 21 in a one-to-one correspondence.
[0036] Regarding the specific structure of the clamping assembly, the preferred embodiment 1 is as follows: Figure 2 and attached Figure 4As shown, the clamping assembly is provided with at least two sets of clamping members 12 (attached Figure 2 Two sets of clamping members 12 are shown in the figure, but the present embodiment 1 is not limited thereto). Each of the clamping members 12 is provided with a support block 120 capable of receiving / supporting a portion of the blade 21, and a pressing member 121 capable of firmly pressing the portion of the blade 21 against the support block 120. It is understandable that by combining the fixed support block 120 with the movable pressing member 121, the blade 21 can be clamped and fixed (see the attached diagram). Figure 5 as shown) or loosen.
[0037] Furthermore, in each of the clamping members 12, a supporting slope 1200 is integrally provided on the top side of the support block 120, which matches the local shape of the blade 21, so that the supporting slope 1200 can fit the local shape of the blade 21 thereon, thereby facilitating the pressing member 121 to firmly press the local part of the blade 21 against the support block 120 to avoid shaking; the pressing member 121 is preferably an elbow clamp (also known as a horizontal quick clamp), and is detachably fixed to the top side of the support block 120 by screws; the elbow clamp is easy to operate, has a good clamping effect, and has a low production cost, which is conducive to production applications.
[0038] Furthermore, in each of the clamping assemblies, at least two groups of the clamping members 12 are spaced apart along the length direction of the blade 21 to achieve balanced and stable clamping and fixing of the blade 21 .
[0039] Next, let's discuss the base plate 10 .
[0040] Based on the shape of the drone blade 2 and to save costs and facilitate installation and use, in this embodiment 1, the bottom plate 10 adopts a rectangular plate shape, which can be seen in the attached figure. Figure 2 As shown. Accordingly, the limit seat 11 is centrally located in the middle of the upper side of the base plate 10, and the two sets of clamping assemblies are respectively located on either side of the limit seat 11 along the length of the base plate 10. That is, the limit seat 11 and the two sets of clamping assemblies are spaced apart along the length of the base plate 10 and fixedly disposed on the upper side of the base plate 10. Furthermore, the limit seat 11 and the plurality of support blocks 120 are each fixed to the upper side of the base plate 10 by rivets or screws.
[0041] In addition, a handle 13 for the operator to hold is fixedly provided on the upper side of the base plate 10, that is, the operator can move the fixing fixture 1 through the handle 13. Furthermore, the handle 13 is detachably mounted on the upper side of the base plate 10 by screws.
