[0037] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "install", "connect", "connect", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can also be a mechanical connection. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0038] Please refer to Figure 1 and Figure 2 The present invention proposes a test piece angle adjustment tool, the adjustment tool includes at least one first adjustment mechanism 10 and at least one second adjustment mechanism 20, each first adjustment mechanism 10 includes a first driving member 110 and an outer frame 120, and the first driving member 110 is used to drive the outer frame 120 to rotate along its axial direction.

[0039] Each second adjustment mechanism 20 includes a support 210 and a second driving member 220. The opposite ends of the support 210 are respectively connected to the outer frame 120. The second driving member 220 is installed on the support 210. A sliding component 211 is provided on the support 210. The sliding component 211 slides with the support 210. The second driving member 220 is used to drive the sliding component 211 to slide along the support 210 to adjust the side slip angle of the test piece 30 installed on the sliding component 211.

[0040] It should be noted that the first driving member 110 is used to drive the outer frame 120 to rotate along its axial direction, and the support 210 is installed on the outer frame 120, and the rotation of the outer frame 120 will drive the support 210 to rotate together. The test piece 30 is installed on the sliding assembly 211, and the sliding assembly 211 can slide relative to the support 210, and then the rotation of the outer frame 120 will drive the test piece 30 to rotate along the axial direction of the outer frame 120.

[0041] At the same time, the second driving member 220 is used to drive the sliding assembly 211 to slide relative to the support 210 , and then the side sliding angle of the test piece 30 is adjusted under the drive of the second driving member 220 .

[0042] It can be seen that under the cooperative driving of the first driving member 110 and the second driving member 220, the test piece 30 can reach a specified angle, thereby realizing adjustment of different angles with a high degree of automation. Compared with the manual adjustment method, the adjustment efficiency of the test piece 30 is higher.

[0043] In one embodiment, the sliding assembly 211 includes a gear ring 212 and a slider 213 disposed on the gear ring 212. The test piece 30 is connected to the gear ring 212 via a support rod 310. A guide rail 214 is provided on the side of the support 210 facing the sliding assembly 211, and the slider 213 slidably cooperates with the guide rail 214.

[0044] The support rod 310 is used to place the test piece 30 in a direction away from the support 210 and the gear ring 212, thereby leaving enough space for testing and also leaving space for adjusting the rotation position of the test piece 30.

[0045] The gear ring 212 is slidably matched with the guide rail 214 via the slider 213 , so that the position of the gear ring 212 relative to the support 210 can be adjusted by the second driving member 220 , and the side slip angle of the test piece 30 can be adjusted under the rotation of the gear ring 212 .

[0046] In some other embodiments, a slider 213 may be provided on the support 210, and a guide rail 214 may be provided on the side of the ring gear 212 facing the support 210, so that the guide rail 214 on the ring gear 212 can slide relative to the slider 213, and the relative sliding between the ring gear 212 and the support 210 can also be satisfied. The setting positions of the slider 213 and the guide rail 214 are not limited here.

[0047] Specifically, the gear ring 212 and the support 210 are both arc-shaped, and the test piece 30 is located at the arc center of the gear ring 212 and the support 210 .

[0048] The gear ring 212 and the support 210 are set to be arc-shaped, so that the side slip angle of the test piece 30 can be adjusted when the gear ring 212 slides relative to the support 210. Preferably, the gear ring 212 and the support 210 are both semicircular. The specific angle can be adjusted according to the actual demand for the side slip angle, which is not limited here.

[0049] Furthermore, the outer end of the ring gear 212 is meshed with the output end gear of the second driving member 220, so that when the output end of the second driving member 220 is running, the ring gear 212 will be driven to rotate, and the rotation of the ring gear 212 will slide relative to the guide rail 214 under the sliding cooperation of the slider 213 and the guide rail 214, and then the side slip angle of the test piece 30 can be adjusted under the rotation of the ring gear 212.

[0050] In one embodiment, the outer frame 120 includes a first rotating disk 121 and a second rotating disk 122 that are spaced apart. The test piece 30 is located between the first rotating disk 121 and the second rotating disk 122, and the first rotating disk 121 and the second rotating disk 122 are both mounted on the base 40 (see below), and the opposite ends of the support 210 extend to the outside of the first rotating disk 121 and the second rotating disk 122 respectively and are connected to the first rotating disk 121 and the second rotating disk 122 respectively; the second driving member 220 is mounted on the outside of the first rotating disk 121 and the second rotating disk 122.

[0051] The first rotating disk 121 and the second rotating disk 122 are spaced apart to provide a test space for the test piece 30, and the opposite ends of the support 210 extend to the outside of the first rotating disk 121 and the second rotating disk 122, so as to facilitate the installation of the second driving member 220 outside the first rotating disk 121 and the second rotating disk 122, and facilitate the control and maintenance of the first driving member 110 and the second driving member 220 outside the outer frame 120. At the same time, it is also to avoid the installation of the first driving member 110 and the second driving member 220 from interfering with the moving path of the test piece 30.

[0052] Specifically, the first rotating disk 121 and the second rotating disk 122 are both provided with avoidance holes 123 , and opposite ends of the support 210 are respectively passed through the avoidance holes 123 and connected to the first rotating disk 121 and the second rotating disk 122 through threaded connectors.

[0053] The avoidance hole 123 includes two upper and lower holes, one of which is used to accommodate the extended support 210, and the other is used to accommodate the extended gear ring 212. Extending the opposite ends of the support 210 to the outside of the outer frame 120 facilitates the disassembly and assembly of the support 210 and the outer frame 120, and at the same time determines the installation position of the second driving member 220.

[0054] Specifically, a seat body is provided at the end of the support 210 , the seat body is located outside the outer frame 120 and is detachably connected to the outer frame 120 via a threaded connector. In order to improve the strength of the seat body, reinforcing ribs may also be provided on the seat body.

[0055] In one embodiment, the length between two opposite ends of the gear ring 212 is at least greater than the distance between the first rotating disk 121 and the second rotating disk 122 .

[0056] It should be noted that one of the first rotating disk 121 and the second rotating disk 122 can be used as a driving disk and the other as a driven disk, so only one first driving member 110 is required.

[0057] Alternatively, the first rotating disk 121 and the second rotating disk 122 may both serve as active disks, and a first driving member 110 is disposed on one side of each of the first rotating disk 121 and the second rotating disk 122 .

[0058] The lengths of the two opposite ends of the gear ring 212 are set to be greater than the distance between the first rotating disk 121 and the second rotating disk 122 in order to facilitate the second driving member 220 to drive the gear ring 212 .

[0059] Specifically, because the second driving member 220 is disposed on the outside of the outer frame 120, one end of the gear ring 212 needs to at least extend to the outside of the outer frame 120 to cooperate with the second driving member 220. When the distance that the gear ring 212 extends is too short, the second driving member 220 cannot continue to drive the gear ring 212 after driving it to the inside of the outer frame 120. At this time, the other end of the gear ring 212 has extended to the outside of the other side of the outer frame 120, and another second driving member 220 cooperates with it. When the gear ring 212 moves to the specified position and needs to return, the other second driving member 220 can be operated to return the gear ring 212 to the initial position, thereby reciprocatingly adjusting the sideslip angle of the test piece 30.

[0060] Alternatively, the gear ring 212 may be set to be long enough to at least meet the position requirement that the test piece 30 needs to reach, and a second driving member 220 may be set. The forward and reverse rotation of the second driving member 220 can drive the gear ring 212 to drive the test piece 30 to reach different inclination positions. The specific number of the second driving members 220 and the length of the gear ring 212 are only given as examples and are not specifically limited.

[0061] Reference Figure 2 In one embodiment, the adjusting tool further includes a base 40 , the outer frame 120 and the first driving member 110 are mounted on the base 40 , and the output end of the first driving member 110 is meshed with the outer end gear of the outer frame 120 .

[0062] That is, the first driving member 110 is disposed outside the outer frame 120 and is gear-engaged with the outer frame 120 .

[0063] It should be noted that a first driving member 110 may be disposed on each of the two opposite sides of the outer frame 120 . The two first driving members 110 may support the outer frame 120 on one hand, and may jointly drive the outer frame 120 to rotate on the other hand.

[0064] Alternatively, a first driving member 110 is disposed on one side of the outer frame 120 , and a rotating shaft and a bearing are disposed on the other side for rotational cooperation. One first driving member 110 can also meet the rotation requirements of the outer frame 120 .

[0065] As for the base 40, a mounting hole for accommodating the outer frame 120 is provided on the base 40, and the first rotating disk 121 and the second rotating disk 122 of the outer frame 120 are respectively arranged on opposite sides of the base 40. One end of the first driving member 110 is fixedly mounted on the base 40, and the output end is a matching gear, which meshes and rotates with the outer peripheral gear of the first rotating disk 121 or the second rotating disk 122, so that the rotation of the first driving member 110 will drive the first rotating disk 121 and / or the second rotating disk 122 to rotate, and then drive the test piece 30 to rotate along the axial direction of the first rotating disk 121 or the second rotating disk 122, thereby adjusting the pitch angle of the test piece 30.

[0066] It should be noted that the first driving member 110 and the second driving member 220 are both driving motors, and the output ends of the driving motors are both provided with shaft sleeves, and the outer side of the shaft sleeves is provided with external gears for meshing and rotating with the gear ring 212 or the gear of the outer frame 120.

[0067] In summary, the test piece angle adjustment tooling of the present invention utilizes the first driving member 110 to drive the outer frame 120 to rotate, thereby driving the test piece 30 to rotate to different angles to adjust the pitch angle of the test piece 30, and under the drive of the second driving member 220, the test piece 30 can be driven to slide relative to the support 210, thereby adjusting the sideslip angle of the test piece 30. The adjustment efficiency and accuracy of different angles of the test piece 30 are higher, and the test cycle of the test piece 30 is shortened.
