DETAILED DESCRIPTION

[0023] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0024] In the present disclosure, the orientation words such as "inner, outer" used herein refer to the inner and outer relative to the outline of the component or structure itself; "first, second" and the like are used to distinguish one element from another element, and do not have sequential and important nature; in addition, the same reference numerals in different reference drawings represent the same elements.

[0025] The present disclosure provides a gearbox assembly turnover device, referring to Figures 1 to 4 the gearbox assembly turnover device includes a base 1, a supporting mechanism 2 and a positioning mechanism 3, wherein the supporting mechanism 2 is rotatably connected to the base 1 about a first pivoting axis A; the positioning mechanism 3 is rotatably connected to the supporting mechanism 2 about a second pivoting axis B, and the positioning mechanism 3 is used to connect the gearbox, wherein the first pivoting axis A and the second pivoting axis B are arranged at an angle.

[0026] Through the above-mentioned scheme, i.e. the gearbox assembly turnover device provided by the present disclosure, when assembling each part (such as a gear) on the gearbox through the device, the base 1 can be placed on a horizontal plane, and after being connected to the gearbox through the positioning mechanism 3, the rotation of the supporting mechanism 2 about the first pivoting axis A and the rotation of the positioning mechanism 3 about the second pivoting axis B in two dimensions in the manner that the first pivoting axis A and the second pivoting axis B are arranged at an angle can conveniently realize the turnover of the gearbox in three-dimensional space, so as to facilitate the assembly of each part with the gearbox and reduce the difficulty of assembling the gearbox.

[0027] The positioning mechanism 3 mentioned in the above embodiments can be any structure capable of being connected to the gearbox and capable of fixing the gearbox to the gearbox assembly turnover device. For example, the positioning mechanism can be a connecting rod and a bolt capable of being connected to a screw mounting position of the gearbox, or a mechanical hand capable of clamping the gearbox and driving the gearbox to turn. The specific components or structures can be selected according to actual conditions, and the disclosure does not make specific limitations thereto.

[0028] In some embodiments, as shown in Figures 1 to 4 The first pivot axis A is an axis perpendicular to the horizontal plane, and the second pivot axis B is an axis parallel to the horizontal plane. In this way, the first pivot axis A and the second pivot axis B perpendicular to each other can realize the three-dimensional turnover of the gearbox when the gearbox assembly turnover device is connected to the gearbox. For example, as shown in Figure 2 The second pivot axis B extends in a direction parallel to the horizontal plane, and when the positioning mechanism 3 rotates around the second pivot axis B, it can drive the gearbox to rotate relative to the horizontal direction. The first pivot axis A extends in a direction perpendicular to the horizontal plane, i.e., in a vertical direction, and when the support mechanism 2 rotates around the first pivot axis A, it can drive the positioning mechanism 3 and the gearbox connected to the positioning mechanism 3 to rotate relative to the vertical direction, thereby realizing the 360° turnover of the gearbox in two dimensions. When assembling parts on the surfaces of the gearbox in different directions, the gearbox can be turned to a direction convenient for manual assembly, thereby facilitating the assembly of the gearbox by the staff.

[0029] In addition, in the above-mentioned way of turning the gearbox, the turning can be electrically driving the support mechanism 2 and the positioning mechanism 3 to rotate, or manually rotating the support mechanism 2 and the positioning mechanism 3. The disclosure will be described in detail below, and no further description is given here.

[0030] In some embodiments, as shown in Figures 1 to 4 The support mechanism 2 includes a first plate body 210 and a second plate body 220 perpendicular to the first plate body 210. The first plate body 210 is rotationally connected to the base 1 with the first pivot axis A as the center, and the positioning mechanism 3 is rotationally connected to the second plate body 220 with the second pivot axis B as the center. In this way, the first plate body 210 and the second plate body 220 perpendicular to each other can provide a turnover space for the gearbox when the gearbox is connected to the positioning mechanism 3, and the first plate body 210 and the second plate body 220 perpendicular to each other can also stably support the gearbox after the gearbox is connected. For example, as shown in Figure 1 and Figure 2As shown, the first plate body 210 and the second plate body 220 are connected to each other perpendicularly and form an L-shaped plate body, the inner side of the bending of the L-shaped plate body can leave a turnover space for the gearbox, and when the gearbox is connected to the positioning mechanism 3, the gearbox can be more balanced supported by the weight of the gearbox and the connection position of the L-shaped plate body and the base 1.

[0034] It should be noted that, since the structures and sizes of the gearboxes of different vehicle models are different, in order to facilitate the gearbox assembly turnover device provided by the present disclosure to turn over different types of gearboxes for assembly, the connecting plate 312 can also be designed to be detachably connected with the rotating shaft 311, and the connecting plate 312 can be replaced to adapt to different sizes of the gearbox, and the plurality of positioning holes on the connecting plate 312 can also be selected at appropriate positions according to the specific positions of the connecting rods 313 connected with the gearbox, in addition, according to the different specific shapes of the gearbox, different lengths of the connecting rods 313 can also be used to connect with different positions of the gearbox, for example, in the examples of Figure 1 and Figure 2 The number of the connecting rods 313 is three, and the lengths of the three connecting rods 313 are different, so as to be connected with different positions of the gearbox, in the embodiments not shown in the drawings, the number of the connecting rods 313 can be more, for example, four or five, or less, two, and the lengths of the plurality of connecting rods 313 can be the same or different, and part of the lengths can be the same and part of the lengths can be different, and the appropriate lengths of the connecting rods 313 can be selected according to the specific structure of the connected gearbox, and the connecting mode of the connecting rods 313 with the connecting plate 312 can also be any suitable mode, for example, in the examples of Figure 1 and Figure 2 The connecting rods 313 are fixed with the connecting plate 312 by screwing the screw through the positioning holes provided in the connecting plate 312 and threadedly connecting the connecting rods 313, and the end surface of the screw abuts against the connecting plate 312.

[0035] In some embodiments, as shown in Figures 1 to 4 , the connecting piece 314 can be moved along the extension direction of the connecting rod 313 by rotating. In this way, when connected to different structures or different size gearboxes through the connecting piece 314, the specific position connected to the gearbox can be fine-tuned by rotating the connecting piece 314 relative to the connecting rod 313, for example, as shown in Figure 1 , Figure 2 and Figure 4 , the connecting piece 314 can be a semicircular arched piece, the part close to one of the arched edges can be provided with a hole body for the screw to pass through, and the part close to the other arched edge can be rotatably connected to the connecting rod 313. When connected to the gearbox through the connecting piece 314, the connecting piece 314 can be rotated to adjust the position connected to the gearbox.

[0036] In some embodiments, the base 1 includes a shaft body 110 and a first bearing 120, wherein the central axis of the shaft body 110 forms a first pivot axis A; the support mechanism 2 is rotatably connected to the shaft body 110 through the first bearing 120.
