Detailed Embodiment

[0018] Please refer to Figure 1 - Figure 2 , the present utility model provides a technical solution: an auxiliary device for processing transmission gears, including a processing table 1. A limiting table 11 is fixedly installed in the middle of the upper surface of the processing table 1. It further includes four clamping blocks 13. The four clamping blocks 13 are evenly distributed outside the limiting table 11. Four first water tanks 12 are opened inside the limiting table 11. The four clamping blocks 13 correspond to the four first water tanks 12 one by one. A first piston 14 is slidably connected inside the first water tank 12. A first connecting rod 15 is horizontally and fixedly installed in the middle of the side of the first piston 14 close to the clamping block 13. One end of the first connecting rod 15 penetrates through the first water tank 12 and is fixedly connected to the middle of one side of the clamping block 13. Four second water tanks 2 are vertically opened at the upper end inside the processing table 1. The tops of the four second water tanks 2 are respectively communicated with the bottoms of the four first water tanks 12. A second piston 21 is slidably connected inside the second water tank 2. A second connecting rod 22 is vertically and fixedly installed in the middle of the bottom side of the second piston 21. An installation groove 23 is opened at the lower end inside the processing table 1. A connecting plate 25 is slidably connected inside the installation groove 23. The bottoms of the four second connecting rods 22 penetrate through the top inner wall of the installation groove 23 and are fixedly connected to the upper surface of the connecting plate 25. An electro - hydraulic push rod 24 is fixedly connected to the bottom inner wall of the installation groove 23 by bolts. The telescopic end of the electro - hydraulic push rod 24 is fixedly connected to the middle of the bottom side of the connecting plate 25.

[0019] In this technical solution, through the limiting platform 11 on the upper surface of the processing table 1, the fixing groove of the gearbox gear can be penetrated, so as to limit the gearbox gear. By controlling the electro-hydraulic push rod 24 to work through the corresponding controller, the push plate can be pushed upward. Through the four groups of second connecting rods 22, the four groups of second pistons 21 can be pushed to move upward in the second water tank 2, so as to press the water into the four groups of first water tanks 12. Further, the water in the first water tank 12 can push the first piston 14 to move in the first water tank 12. Through the four groups of first connecting rods 15, the four groups of clamping blocks 13 can be pushed to move in the opposite direction and press against the inner wall of the fixing groove of the gearbox gear, so as to effectively fix the gearbox gear.

[0020] In this embodiment, four groups of storage grooves 17 are opened on the outer side of the limiting platform 11. The storage grooves 17 are matched with the sizes of the clamping blocks 13. A return spring 16 is sleeved on the outer side of the first connecting rod 15. The two ends of the return spring 16 are respectively fixedly connected with the first piston 14 and the inner wall of the first water tank 12.

[0021] In this technical solution, when it is necessary to remove the processed gearbox gear, by controlling the electro-hydraulic push rod 24 to work through the corresponding controller, the connecting plate 25 can be pulled downward to reset. Through the second connecting rod 22, the second piston 21 can be pulled to move downward in the second water tank 2, so as to pump the water in the first water tank 12 back into the second water tank 2. Through the elastic force of the return spring 16 on the outer side of the first connecting rod 15, the four groups of first pistons 14 can be pushed to move relatively. Further, the four groups of first connecting rods 15 can pull the four groups of clamping blocks 13 into the storage grooves 17, which is convenient for the staff to remove the processed gearbox gear.

[0022] In this embodiment, the first connecting rod 15 is matched with the size of the first water tank 12, the first water tank 12 is matched with the size of the second water tank 2, and the second connecting rod 22 is matched with the sizes of the second piston 21 and the installation groove 23.

[0023] In this technical solution, through the matching of the size of the first connecting rod 15 and the first water tank 12, the first water tank 12 can accommodate the first connecting rod 15, avoiding the excessive length of the first connecting rod 15 and affecting the fixing of the installation groove 23 of the gearbox gear by the clamping block 13.

[0024] When an auxiliary device for processing transmission gears is in use, through the limiting platform 11 on the upper surface of the processing table 1, the fixing groove of the transmission gear can be penetrated, so as to limit the transmission gear. By controlling the electro-hydraulic push rod 24 to work through the corresponding controller, the push plate can be pushed upward. Through the four groups of second connecting rods 22, the four groups of second pistons 21 can be pushed to move upward in the second water tank 2, so as to press the water into the four groups of first water tanks 12. Further, the water in the first water tank 12 can push the first piston 14 to move in the first water tank 12. Through the four groups of first connecting rods 15, the four groups of clamping blocks 13 can be pushed to move in the opposite direction and abut against the inner wall of the fixing groove of the transmission gear, so as to effectively fix the transmission gear. When it is necessary to remove the processed transmission gear, by controlling the electro-hydraulic push rod 24 to work through the corresponding controller, the connecting plate 25 can be pulled downward to reset. Through the second connecting rod 22, the second piston 21 can be pulled to move downward in the second water tank 2, so as to pump the water in the first water tank 12 back into the second water tank 2. Through the elastic force of the return spring 16 outside the first connecting rod 15, the four groups of first pistons 14 can be pushed to move relatively. Further, the four groups of first connecting rods 15 can pull the four groups of clamping blocks 13 into the storage groove 17, which is convenient for the staff to remove the processed transmission gear.
