[0033] The assembly of the tripod pin 50 requires that the three ball heads 512 and the three ball rings 52 on the tripod frame 51 are respectively snapped together. The commonly used method is to manually align and then tighten. The snapping of the ball head 512 and the ball ring 52 requires that the ball ring 52 and the ball head 512 are contacted and then tightened. Moreover, one tripod pin 50 needs to repeat the above steps three times before it can be installed. The operator is required to have a certain level of proficiency, the assembly is relatively complicated, and the assembly efficiency is low.

[0034] This embodiment discloses a tripod 50 assembly tool, such as Figure 1 and Figure 5 As shown, it may include a workbench 10 , three sets of rotating components 20 and a driving component 30 .

[0035] The workbench 10 can serve as a tooling frame to play a supporting role, and the rotating assembly 20 and the driving unit 31 are both arranged on the workbench 10 .

[0036] The three groups of rotating components 20 are distributed in a ring around the reference axis L1. The rotating component 20 may include a rotating unit 21, a rotating shaft 22 and a positioning ring 23. The rotating unit 21 may be rotatably connected to the workbench 10 through the rotating shaft 22, so as to rotate to a set angle to achieve loosening and pressing actions. The plane where the axes of the three rotating shafts 22 are located is the first plane, and the reference axis L1 is perpendicular to the first plane. The positioning ring 23 may be fixedly connected to the rotating unit 21, the axis of the positioning ring 23 is perpendicular to the rotating shaft 22, and the axis of the positioning ring 23 intersects with the reference axis L1. As a preferred embodiment, the first plane Q1 may be a horizontal plane, the reference axis L1 may be vertically arranged, and the rotating shaft 22 may be horizontally arranged. This facilitates placing the tripod 51 on the workbench 10 from above the workbench 10, and placing the ball ring 52 on the positioning ring 23.

[0037] The driving assembly 30 can be detachably connected to the workbench 10 , and the driving assembly 30 can drive the three rotating units 21 to rotate synchronously along a first rotation direction, where the first rotation direction is a direction in which the positioning ring 23 rotates toward the reference axis L1 .

[0038] like Figure 2 , Figure 3 and Figure 6 As shown, the positioning ring 23 can be engaged with the ball ring 52 to achieve accurate positioning of the ball ring 52, and then the annular base 511 is placed in the middle of the three groups of rotating components 20. Specifically, the ball ring 52 can be placed first, and under the positioning of the positioning ring 23, the angle between the axis of the ball ring 52 and the reference axis L1 is an acute angle, and then the ball head 512 on the tripod 51 is set in the ball ring 52. It should be understood that the ball head 512 on the tripod 51 corresponds to the ball ring 52 one by one. When the rotating component 20 rotates around the rotating shaft 22 in the direction of the reference axis L1, the ball ring 52 can be pressed onto the ball head 512.

[0039] In this embodiment, if Figure 6As shown, the rotating unit 21 includes a first push plate 211 and a second push plate 212. The first push plate 211 and the second push plate 212 are integrally formed, and the rotating shaft 22 is located at the connecting portion of the first push plate 211 and the second push plate 212. The positioning ring 23 is located on the side of the first push plate 211 facing the reference axis L1. The length direction of the first push plate 211 is perpendicular to the rotating shaft 22, and the length direction of the second push plate 212 is perpendicular to the rotating shaft 22. In the projection of the rotating unit 21 along the direction parallel to the rotating shaft 22, there is an angle between the first push plate 211 and the second push plate 212, and the angle can be an obtuse angle. In other embodiments, the angle between the first push plate 211 and the second push plate 212 can be a right angle or an acute angle, and the driving unit 31 can make adaptive adjustments according to the angle to push the second push plate 212, and at the same time, the first push plate 211 will rotate around the rotating shaft 22 in the direction close to the reference axis L1, so that the ball ring 52 is engaged with the ball head 512. When the angle between the first push plate 211 and the second push plate 212 is a right angle or an acute angle, the angle between the length direction of the first push plate 211 and the reference axis L1 is smaller, and the angle between the length direction of the second push plate 212 and the reference axis L1 is larger, so that the rotating unit 21 tends to rotate toward the second push plate 212. After completing the assembly of the tripod pin 50, the rotating unit 21 can automatically reset.

[0040] In this embodiment, if Figure 6 As shown, the rotating unit 21 also includes a first limiting protrusion and a second limiting protrusion. The first limiting protrusion and the second limiting protrusion are located on the side of the first push plate 211 facing the reference axis L1, and the positioning ring 23 is located between the first limiting protrusion and the second limiting protrusion. One end of the first limiting protrusion and the second limiting protrusion is fixedly connected to the first push plate 211, and the other end extends in a direction perpendicular to the first push plate 211. The first limiting protrusion can be longer than the second limiting protrusion, supporting the ball ring 52 from the bottom end so that it is not easy to fall off. At the same time, the second limiting protrusion is shorter, which can make it easier for the ball ring 52 to fit with the ball head 512 for press-fitting.

[0041] In this embodiment, if Figure 4 As shown, the assembly tool of the tripod 50 may also include a connecting component 40, and the connecting component 40 may include a supporting block 41 and three connecting blocks 42. The three connecting blocks 42 are arranged in a ring around the reference axis L1, and the connecting blocks 42 are detachably connected to the workbench 10. The three connecting blocks 42 are staggered with the three rotating units 21. The three connecting blocks 42 are distributed around the supporting block 41. The supporting block 41 is fixedly connected to the three connecting blocks 42 respectively, and the rotating shaft 22 is rotatably connected to two adjacent connecting blocks 42, so that the three rotating units 21 are also rotatably connected to the connecting blocks 42 through the rotating shaft 22. When the tool is assembled, the rotating unit 21 can be installed and fixed more conveniently.

[0042] In this embodiment, if Figure 3As shown, the assembly tool of the tripod 50 may also include a positioning rod, which is coaxial with the reference axis L1 and detachably connected to the support block 41. The positioning rod is provided to facilitate the positioning of the tripod frame 51. When assembling the tripod 50, the annular base 511 can be sleeved on the positioning rod so that the ball head 512 and the ball ring 52 are accurately aligned.

[0043] In this embodiment, if Figure 3 As shown, the drive assembly 30 may include a cylinder and a drive block 32. The cylinder is detachably connected to the workbench 10, and the piston rod of the cylinder is parallel to the reference axis L1. The end of the drive block 32 away from the cylinder has a conical surface, and the axis of the conical surface is coaxial with the reference axis L1. One end of the rotating unit 21 is in sliding contact with the conical surface. The drive block 32 is located on the side of the first plane Q1 away from the positioning ring 23. When the tripod pin 50 is pressed, it is only necessary to start the cylinder, and the drive block 32 is pushed upward by the action of the piston rod, and the first push plate 211 will rotate around the rotating shaft 22 in the direction close to the reference axis L1, so that the ball ring 52 is pressed onto the ball head 512. This driving method has a simple structure and low cost.

[0044] In another embodiment, if Figure 5 As shown, each group of rotating components 20 can correspond to a second plane Q2, the axis of the rotating shaft 22 is located in the second plane Q2, and the reference axis L1 is parallel to the second plane Q2. The center of gravity of the rotating unit 21 is located on the side of the second plane Q2 away from the reference axis L1, and the distance from the center of gravity of the rotating unit 21 to the reference axis L1 is greater than the distance from the rotating shaft 22 to the reference axis L1. The rotating unit 21 can include an initial posture and a clamping posture. The driving component 30 can drive the rotating unit 21 to rotate from the initial posture toward the clamping posture. When the driving component 30 stops working, the driving component 30 will automatically convert from the clamping posture to the initial posture under the action of gravity. When the rotating unit 21 is in the initial posture, the rotating unit 21 abuts against the driving component 30 under the action of gravity, and the angle between the axis of the positioning ring 23 and the reference axis L1 is an acute angle. This method of resetting by gravity is highly reliable and has a long service life.

[0045] In another embodiment, the assembly tool of the tripod 50 may further include an elastic component. The elastic component is detachably connected to the workbench 10, and the elastic component is detachably connected to the rotating unit 21. The elastic unit may be a spring or a torsion spring, and the elastic unit may be arranged in a one-to-one correspondence with the rotating shaft 22. The rotating unit 21 includes an initial posture and a clamping posture. The driving component 30 may drive the rotating unit 21 to rotate from the initial posture toward the clamping posture. When the rotating unit 21 is in the initial posture, the rotating unit 21 may abut against the driving component 30 under the action of the elastic component, and the angle between the axis of the positioning ring 23 and the reference axis L1 is an acute angle. After completing a press-fitting, the elastic component may drive the three rotating units 21 to rotate to the initial posture along the second rotation direction. The second rotation direction is opposite to the first rotation direction. Using the elastic unit for resetting can simplify the structural design of the rotating unit 21.

[0046] In this embodiment, if Figure 3 As shown, the assembly tool of the tripod 50 may also include a pressure rod, which is slidably connected to the workbench 10 along the reference axis L1, and the pressure rod and the positioning ring 23 are located on the same side of the first plane Q1. The assembly of the tripod 50 requires sufficient driving force. In order to avoid over-reliance on the power of the driving assembly 30, the assembly efficiency of the tripod 50 can be improved by the downward pressing action of the pressure rod on the annular base 511.

[0047] In this embodiment, a tripod 50 assembly method is provided, and the tripod 50 assembly method is applied to any of the tripod 50 assembly tools in the above embodiments, such as Figure 7 As shown, the assembly method of the tripod pin 50 may include steps S10 to S20, and each step is described in detail as follows:

[0048] Step S10, after the tripod 51 and the ball ring 52 are positioned in the tripod 50 assembly tool, the drive assembly 30 can be controlled to operate, and the drive block 32 moves upward, so that the rotating unit 21 is forced to rotate along the first rotation direction until the ball ring 52 is pressed against the ball head 512 of the tripod 51;

[0049] Among them, when the tripod 51 and the ball ring 52 are positioned in the tripod 50 assembly tool, the angle between the axis of the ball ring 52 and the reference axis is an acute angle, and the ball head 512 of the tripod 51 corresponds to the ball ring 52 one by one. As a preferred embodiment, when the first plane is a horizontal plane, when the tripod 51 is positioned, the bottom part of the ball head 512 of the tripod 51 is placed in the ball ring 52.

[0050] Step S20, after the ball ring 52 is pressed onto the ball head 512 of the tripod 51, the driving assembly 30 stops running and controls the rotating unit 21 to rotate along the second rotation direction until the rotating unit 21 is separated from the ball ring 52, and the assembly is completed.

[0051] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present disclosure, and in actual applications, various changes may be made thereto in form and detail without departing from the scope of the present disclosure.
