DETAILED DESCRIPTION

[0024] The first point positioning mechanism 11 includes: a cylindrical positioning pin, which extends into a first positioning hole in the gearbox body; the second point positioning mechanism 12 includes: a prism positioning pin, which extends into a second positioning hole in the gearbox body. The first positioning fixture performs two-point positioning first.

[0025] The edge support mechanism 14 includes: at least three support columns, the support columns support the edge of the gearbox body, and at least three support columns are located in a position that can be connected to form three points in a plane to stably support the gearbox body.

[0026] The side positioning mechanism 13 comprises at least three close-fitting columns, which are located beside the supporting columns and are in close contact with the outer wall of the gearbox body.

[0027] The first clamping actuator 15 includes: a rotary cylinder 151 and a clamping arm 152 . The rotary cylinder 151 is mounted on the first base 10 . The output shaft of the rotary cylinder 151 is connected to the clamping arm 152 . The clamping arm 152 is used to clamp the outer wall of the gearbox body.

[0028] like Figure 3 as well as Figure 4 As shown, the multi-model gearbox body shared production line also includes: a second positioning fixture, the second positioning fixture includes: a second base 20, a first edge insertion column 21, a second edge insertion column 22 and a second clamping actuator 23, the first edge insertion column 21, the second edge insertion column 22 and the second clamping actuator 23 are installed on the second base 20, a connecting ring is provided at one end of the gearbox body, and a first connecting ear, a second connecting ear, a third connecting ear, a fourth connecting ear and a fifth connecting ear are provided at the other end of the gearbox body, the first connecting ear and the second connecting ear are both provided with a first circular hole, and the first The connecting ear and the second connecting ear are relatively arranged on one end of the gearbox body, the first edge insertion column 21 supports the first connecting ear and extends into the first circular hole, the second edge insertion column 22 supports the second connecting ear and extends into the second circular hole, the third connecting ear is arranged in the middle of the first side between the first connecting ear and the second connecting ear, the fourth connecting ear and the fifth connecting ear are arranged on the second side between the first connecting ear and the second connecting ear, the fourth connecting ear is located next to the first connecting ear, and the fifth connecting ear is located next to the second connecting ear, and the second clamping actuator 23 is used to support and clamp the third connecting ear, the fourth connecting ear and the fifth connecting ear.

[0029] The second clamping actuator 23 includes: a clamping pad 231 and a clamping actuator assembly 232. The clamping pad 231 is relatively isolated from the second base 20. The clamping pad 231 is equipped with a clamping actuator assembly 232. The clamping actuator assembly 232 is used to clamp the third connecting ear, the fourth connecting ear or the fifth connecting ear onto the clamping pad 231. The structure of the clamping actuator assembly 232 is the same as that of the first clamping actuator 15. The clamping pad 231 supports the third connecting ear, the fourth connecting ear or the fifth connecting ear. These three supporting points and three-point fixed surface realize the support of the gearbox body at three positions, ensuring that the gearbox body can be initially suspended by the three supporting points, thereby realizing stable support. The second positioning fixture realizes the positioning of the gearbox body in the second processing step on the production line.

[0030] A side post 24 is installed on the second base 20. There are at least three side posts 24, and all side posts 24 are used to surround the outside of the gearbox body connecting ring. Since the five supporting points are at the top of the gearbox body, the side posts 24 are designed to prevent the bottom of the gearbox body from swinging.

[0031] A support portion 25 is mounted on the second base 20, and the support portion 25 is used to support the middle of the second side of the gearbox body. Since the first side of the gearbox body has been supported in the middle at the third connecting ear, in order to avoid deformation of the second side of the gearbox body during processing, the support portion 25 is designed to avoid deformation of the middle of the second side of the gearbox body. (Although the clamping pad 231 supports the third connecting ear, the fourth connecting ear or the fifth connecting ear, these three supporting points have preliminarily positioned the gearbox body product, but because the gearbox body product is large and long, the strength is not good during processing, so a support part 25 for an auxiliary adaptive support mechanism is added. Since the second side span of the gearbox body is long, an auxiliary adaptive support mechanism is set in the middle part of the second side of the gearbox body with a longer span. The support part 25 includes: a lifting drive structure and a floating support column. The output end of the lifting drive structure is connected to the floating support column. The floating support column can be lifted and lowered relative to the lifting drive structure. The floating support column supports the middle part of the second side of the gearbox body. At this time, the gearbox body is a blank and the height is unstable. Therefore, a floating support column is set to adjust the height to adapt to the height change of the gearbox body blank. If there is no such support, the strength here is not good during processing, which makes the gearbox body blank easy to deform and damage). After the clamping pad 231 supports the third connecting ear, the fourth connecting ear and the fifth connecting ear, the support of the support part 25 is adjusted. The lifting drive structure can be driven by oil pressure or the like.

[0032] like Figure 5 as well as Figure 6As shown, the multi-model gearbox housing shared production line also includes: a third positioning fixture, the third positioning fixture includes: a third base 30, a first positioning column 31, a second positioning column 32, a support pad 33 and a third clamping actuator 34, the first positioning column 31 and the second positioning column 32 are installed on the third base 30, the first positioning column 31 extends into the first through hole opened in the middle of the gearbox housing, the second positioning column 32 extends into the second through hole opened in the middle of the gearbox housing, a plurality of support pads 33 surround the first positioning column 31 and the second positioning column 32, the support pads 33 are used to support the edge of the gearbox housing, a third clamping actuator 34 is installed next to the support pad 33, and the third clamping actuator 34 is used to clamp the edge of the gearbox housing located on the support pad 33. The third positioning fixture realizes the second step of positioning the gearbox housing on the production line. The third positioning fixture realizes the third processing step of positioning the gearbox housing on the production line. In the third positioning fixture, first, the first through-hole and the second through-hole of the gearbox body are positioned by the larger first positioning column 31 and the second positioning column 32, so that the gearbox body is positioned at two points first; then, a support pad 33 is provided to support the edge of the gearbox body, and the number and distribution position of the support pad 33 can be adjusted to stably support the gearbox body and avoid the position change of the gearbox body during processing; finally, the third clamping actuator 34 presses the edge of the gearbox body on the support pad 33, thereby achieving stable support of the gearbox body and adapting to a variety of gearbox bodies. As long as the gearbox body has the first through-hole and the second through-hole, it can be positioned on the support pad 33.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
