[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a transmission front housing rotation positioning device, including a mounting frame, a clamping mechanism for fixing and clamping the transmission front housing on one side of the mounting frame, a rotating mechanism for driving the clamping mechanism to rotate on the mounting frame, and a cleaning mechanism for cleaning the inner wall of the transmission front housing fixedly clamped by the clamping mechanism on the rotating mechanism.

[0008] The clamping mechanism is provided with a hollow rotating shaft. One end of the hollow rotating shaft passes through a bearing at the center of the outer wall of the limiting disk and is connected to the hollow diverter plate. The hollow diverter plate is provided with jet pipes in a ring array on its circumferential outer wall.

A second reduction motor is installed on the outer wall of the other side of the mounting plate.

[0009] The cleaning mechanism is equipped with an air pump. The exhaust end of the air pump is connected to a rigid connecting pipe through a flexible connecting pipe. The other end of the rigid connecting pipe is installed in a sealed bearing on the inner circumferential wall of the other end of the hollow rotating shaft.

[0010] Preferably, the rotating mechanism is composed of a first geared motor, a rotating plate, an annular slide rail, an arc-shaped slider, and a connecting shaft. The connecting shaft is installed at the center of one side of the outer wall of the rotating plate. The other end of the connecting shaft passes through a bearing on the outer wall of the mounting frame and is connected to the first geared motor through a coupling. The geared motor is mounted on the mounting frame.

[0011] Preferably, arc-shaped sliders are installed on both sides of the outer wall of one side of the rotating plate, and the other end of the arc-shaped sliders is installed on an annular slide rail, and the arc-shaped sliders and the annular slide rail are slidably connected.

[0015] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0016] 1. In this utility model, through a series of coordinated structural arrangements, when the operator clamps the transmission, after placing one end of the transmission front housing inside the four clamping plates, the operator starts the second reduction motor. The start of the second reduction motor indirectly drives the spiral disk to rotate forward or backward. The rotation of the spiral disk causes the clamping plates to move outward or inward. The operator uses the second reduction motor to drive the spiral disk to move the clamping plates to clamp the transmission front housing. The operator then starts the first reduction motor, which indirectly drives the transmission front housing clamped by the clamping mechanism to rotate. The rotation of the transmission front housing changes the position to be processed. Thus, this utility model not only facilitates the operator in clamping transmission front housings of different outer diameters, but also facilitates the operator in adjusting the position to be processed on the transmission front housing, making it convenient to operate and use.

[0017] 2. In this utility model, through a series of coordinated structural arrangements, when external equipment processes the front housing of the transmission, the air pump on the cleaning mechanism is activated. When the debris generated during the processing of the front housing falls into the interior of the front housing, the air pump sequentially delivers the generated gas through a soft connecting pipe, a hard connecting pipe, a hollow rotating shaft, and a hollow splitter plate to the jet pipe. The gas discharged from the jet pipe blows towards the inner wall of the front housing and blows the debris inside the front housing to the outside. Thus, this utility model can effectively remove the debris that falls onto the inner wall of the front housing during processing, eliminating the need for subsequent cleaning equipment to clean the debris adhering to the inner wall of the front housing, thereby improving the efficiency of the front housing production and processing.

[0035] like Figure 1-7As shown, a transmission front housing rotation positioning device includes a mounting bracket 100. A clamping mechanism 400 for fixing and clamping the transmission front housing is provided on one side of the mounting bracket 100. A rotating mechanism 200 for driving the clamping mechanism 400 to rotate is provided on the mounting bracket 100. A cleaning mechanism 500 for cleaning the inner wall of the transmission front housing fixed and clamped by the clamping mechanism 400 is provided on the rotating mechanism 200.

[0036] A hollow rotating shaft 460 is provided on the clamping mechanism 400. One end of the hollow rotating shaft 460 passes through the bearing at the center of the outer wall of the limiting disk 430 and is connected to the hollow diverter plate 440. The hollow diverter plate 440 is provided with jet pipes 441 in a ring array on the outer wall of the circumference. The other end of the hollow rotating shaft 460 passes through the bearing at the center of the outer wall of the mounting plate 450. A second reduction motor 470 is installed on the outer wall of the other side of the mounting plate 450.

[0037] The cleaning mechanism 500 is equipped with an air pump 510. The exhaust end of the air pump 510 is connected to the rigid connecting pipe 530 through a flexible connecting pipe 520. The other end of the rigid connecting pipe 530 is installed in a sealed bearing on the inner circumferential wall of the other end of the hollow rotating shaft 460.

[0038] The rotating mechanism 200 is composed of a first reduction motor 210, a rotating plate 220, an annular slide rail 230, an arc-shaped slider 240, and a connecting shaft 250. The connecting shaft 250 is installed at the center of one outer wall of the rotating plate 220. The other end of the connecting shaft 250 passes through a bearing on the outer wall of the mounting frame 100 and is connected to the first reduction motor 210 through a coupling. The reduction motor is mounted on the mounting frame 100. When the first reduction motor 210 starts, it drives the connecting shaft 250 to rotate. When the connecting shaft 250 rotates, it drives the rotating plate 220 to rotate. The rotation of the rotating plate 220 drives the clamping mechanism 400 to rotate through the connecting rod 300.

[0039] Arc-shaped sliders 240 are installed on both sides of the outer wall of one side of the rotating plate 220. The other end of the arc-shaped sliders 240 is installed on the annular slide rail 230, and the arc-shaped sliders 240 and the annular slide rail 230 are slidably connected. The annular slide rail 230 is installed on the outer wall of one side of the mounting bracket 100. The arrangement of the arc-shaped sliders 240 and the annular slide rail 230 enhances the stability of the rotating plate 220 when rotating, thereby enhancing the stability of the front housing of the transmission held by the clamping mechanism 400 when rotating.

[0040] The air pump 510 is installed on the outer wall of the other side of the rotating plate 220, and the outer wall of the other side of the rotating plate 220 is connected to the mounting plate 450 through the connecting rod 300.

[0041] A drive pulley is mounted on the output shaft of the second geared motor 470. The drive pulley is connected to the driven pulley via a transmission belt. The driven pulley is located on one side of the outer wall of the hollow rotating shaft 460. When the second geared motor 470 starts, it drives the drive pulley to rotate. When the drive pulley rotates, it drives the driven pulley to rotate via the transmission belt. When the driven pulley rotates, it drives the hollow rotating shaft 460 to rotate. When the hollow rotating shaft 460 rotates, it drives the spiral disc 410 to rotate.

[0042] An installation plate 450 is installed on one outer wall of the limiting plate 430. A spiral plate 410 is provided between the limiting plate 430 and the installation plate 450. The spiral plate 410 is provided on the outer wall of the hollow rotating shaft 460. A clamping plate 420 is provided between the limiting plate 430 and the spiral plate 410.

[0043] Working Principle: In use, after connecting to an external power source, when the operator clamps the gearbox, they place one end of the gearbox front housing inside the four clamping plates 420. The operator then starts the second reduction motor 470, which indirectly drives the spiral disk 410 to rotate forward or backward. This rotation causes the clamping plates 420 to move outward or inward, allowing the second reduction motor 470 to drive the spiral disk 410 and the clamping plates 420 to clamp the gearbox front housing. The operator then starts the first reduction motor 210, which indirectly rotates the gearbox front housing clamped by the clamping mechanism 400. This rotation changes the desired processing position, thus facilitating the operation of gearboxes with different outer diameters. The fixed clamping of the transmission front housing facilitates the adjustment of the processing position by the operator, making it easy to operate. When external equipment processes the transmission front housing, the air pump 510 on the cleaning mechanism 500 is activated. When the debris generated during the processing of the transmission front housing falls into the interior of the transmission front housing, the air pump 510 delivers the generated gas sequentially through the soft connecting pipe 520, the rigid connecting pipe 530, the hollow rotating shaft 460, and the hollow diverter plate 440 to the jet pipe 441. The gas discharged from the jet pipe 441 blows towards the inner wall of the transmission front housing and blows the debris inside the transmission front housing to the outside. Thus, this invention can effectively remove the debris that falls onto the inner wall of the transmission front housing during processing, eliminating the need for subsequent cleaning equipment to clean the debris adhering to the inner wall of the transmission front housing, thereby improving the efficiency of transmission front housing production and processing.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
