[0022] The following is a combination of the appended examples of the present invention Figure 1-5 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] As shown in the figure, a shell cleaning device for reducer production includes a frame 1, on which a ring-shaped purge pipe 2 is rotatably provided and is transmission-connected to a first driving source provided on the frame 1. The purge pipe 2 is driven by the first driving source to rotate along the center of the purge pipe 2. The inner side surface of the purge pipe 2 is connected to a plurality of purge nozzles 21 arranged along the center ring array of the purge pipe 2 and connected to the inside of the purge pipe 2. The ports of the purge nozzles 21 face the central axis of the purge pipe 2. A clamp 3 transmission-connected to a second driving source provided on the frame 1 is slidingly provided on the frame 1. The clamp 3 is driven by the second driving source to slide through the purge pipe 2 in a direction parallel to the central axis of the purge pipe 2.

[0024] Specifically, the purge pipe 2 is rotatably arranged on the frame 1 and is transmission-connected to the first driving source: a supporting ring 4 is fixedly arranged on the frame 1, and a mounting ring groove 41 matching the purge pipe 2 is opened on the inner wall of the supporting ring 4, and the purge pipe 2 is arranged in the mounting ring groove 41, and a first sliding groove 42 and a second sliding groove 43 symmetrical along the center of the supporting ring 4 are opened on the bottom of the mounting ring groove 41. The outer surface of the purge pipe 2 is connected with a connecting pipe 22 and a transmission rod 23 symmetrical along the center of the purge pipe 2, and the connecting pipe 22 is connected to the interior of the purge pipe 2 and passes through the first sliding groove 42. The first driving source is a cylinder 5 hinged on the frame 1, and the transmission rod 23 is hinged to the output shaft of the cylinder 5 through the second sliding groove 43. Through the above structure, the purge pipe 2 can be rotatably maintained in the mounting ring groove 41, and the cylinder 5 drives the transmission rod 23 to swing back and forth in the second sliding groove 43, and the transmission rod 23 drives the purge pipe 2 to rotate back and forth in the mounting ring groove 41.

[0025] Specifically, the structure of the clamp 3 is as follows: the clamp 3 includes a first support plate 31, a second support plate 32 and a sliding plate 33 arranged parallel to each other, the first support plate 31 and the second support plate 32 are connected by at least two connecting rods 34, the sliding plate 33 is passed through the connecting rod 34, a locking rod 35 is hinged on the first support plate 31, a locking groove 331 matching the locking rod 35 is provided on the sliding plate 33, the locking rod 35 can be inserted into the locking groove 331 and a locking nut 36 is screwed on the locking rod 35, and the cross-section of the first support plate 31 and the second support plate 32 is L-shaped.

[0026] Specifically, the clamp 3 is slidably arranged on the frame 1 and is connected to the second driving source by transmission: the frame 1 is provided with two linear slide rails 6 respectively located on one side of the first support plate 31 and the second support plate 32 and passing through the purge pipe 2, and the first support plate 31 and the second support plate 32 are each connected to a rotating shaft 37, and the two rotating shafts 37 are respectively arranged on the sliding seats of the two linear slide rails 6, and the second driving source is a synchronous belt 7 connected to the motor transmission arranged on the frame 1, and the sliding seat of the linear slide rail 6 is fixedly connected to the synchronous belt 7.

[0027] When the cam 33 is in the unlocking state, the locking lever 35 is locked and the locking lever 331 is locked. The clamp 3 is driven to move the reducer housing toward the purging pipe 2. In the process of the reducer housing moving toward the purging pipe 2 with the clamp 3 and passing through the purging pipe 2, the purging pipe 2 is connected to the external air supply equipment through the connecting pipe 22. The air supply equipment works to deliver high-pressure airflow into the purging pipe 2. The high-pressure airflow entering the purging pipe 2 flows out from the purging nozzle 21 and blows toward the moving reducer housing. At the same time, the cylinder 5 drives the purging pipe 2 to swing back and forth and drives the purging nozzle 21 to swing back and forth. Through the reciprocating swing of the purging nozzle 21 and the movement of the reducer housing, the high-pressure airflow blown toward the reducer housing can cover the reducer housing without dead angles, thereby achieving a more thorough cleaning effect. After cleaning is completed, the reducer housing can be removed from the clamp 3.

[0028] Furthermore, the frame 1 is provided with a rack 8 located below the moving path of the rotating shaft 37, and the rotating shaft 37 is fixedly connected with a gear 38 that can move with the rotating shaft 37 and engage with the rack 8, and the rotating shaft 37 is rotatably set on the sliding seat of the linear slide rail 6.

[0029] Specifically, the rotating shaft 37 is rotatably arranged on the sliding seat of the linear slide rail 6: a ball bearing 39 is connected to the rotating shaft 37, and a placement groove 61 matching the ball bearing 39 is opened on the sliding seat of the linear slide rail 6, and the ball bearing 39 is placed in the placement groove 61.

[0030] In the above preferred embodiment, during the movement of the clamp 3 through the purge pipe 2, the gear 38 engages with the rack 8. Through the cooperation of the gear 38 and the rack 8, the rotating shaft 37 rotates on the sliding seat of the linear slide 6 while the clamp 3 moves, thereby driving the clamp 3 and the reducer housing fixed on the clamp 3 to rotate. Through the rotation of the reducer housing, the high-pressure airflow blown out from the purge nozzle 21 can be blown onto the reducer housing from multiple angles, so that the high-pressure airflow can more comprehensively cover the interior and surface of the reducer housing, achieving a more thorough cleaning effect. By placing the ball bearing 39 in the placement groove 61 to realize the rotatable connection between the rotating shaft 37 and the sliding seat of the linear slide 6, it is convenient to connect the clamp 3 with the sliding seat of the linear slide 6, so that the worker can fix the reducer housing on the clamp 3 in advance when operating, and then connect the clamp 3 to the sliding seat of the linear slide 6, thereby facilitating the loading and unloading operations of the reducer housing during cleaning.

[0031] Preferably, the purging nozzle 21 is tilted in the direction opposite to the moving direction of the clamp 3, so that the port of the purging nozzle 21 is tilted in the direction opposite to the moving direction of the clamp 3, and thus the high-pressure airflow blown from the purging nozzle 21 to the reducer housing fixed on the clamp 3 is blown onto the reducer housing in the opposite direction of the moving direction of the reducer housing, so that the dust debris blown off the reducer housing falls in the direction opposite to the moving direction of the reducer housing, and does not fall on the reducer housing that has been cleaned, thereby ensuring the cleaning effect.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
