[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The engine housing is processed using a deburring device. This device consists of a motor protective shell, a servo motor, a connecting column, a sliding column, a fixed shell, a fixed shaft, and a fixed connecting rod. First, the servo motor is started, and its output drives the first threaded rod to rotate. This rotation moves the connecting column, which in turn moves the sliding column. The sliding column then moves the pull rod, which moves within a groove. The machine then opens up using the fixed connecting rod as a fixed point, allowing the cylindrical engine housing to be placed into the fixed wall. The servo motor is then started again to reset and fix the cylindrical engine housing. This device can be adjusted for cylindrical engine housings of different sizes and can also achieve center calibration of the cylindrical engine housing, thereby improving processing accuracy.

[0014] 2. The engine housing uses a deburring device with a sliding groove, a snap-fit ​​groove, a limiting block, an electric push rod, and a return spring. When the cylindrical engine housing enters the fixed wall, it compresses the limiting block, pulling the return spring to prevent it from being fixed all the way in. When it is necessary to remove the cylindrical engine housing, simply activate the electric push rod. The electric push rod pushes the limiting block forward, which in turn pushes the cylindrical engine housing outward, facilitating its removal. This automation reduces operator workload and alleviates worker stress. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a deburring processing device for engine housing, including a processing frame 1, a motor protective shell 2 fixedly connected inside the processing frame 1, a servo motor 3 fixedly connected inside the motor protective shell 2, a first threaded rod 21 fixedly connected to the output end of the servo motor 3, a connecting post 4 sleeved on the external thread of the first threaded rod 21, a sliding post 5 fixedly connected to one end of the connecting post 4, a fixed shell 6 fixedly connected inside the motor protective shell 2, and a fixed shaft 7 fixedly connected to the outer arc surface of the fixed shell 6, the number of fixed shafts 7 being four;

[0022] A fixed connecting rod 8 is movably connected to the fixed shaft 7. One end of the fixed connecting rod 8 is connected to the fixed wall 9 via a pin. The outer arc surface of the sliding column 5 is connected to a pull rod 10 via a pin. There are several pull rods 10. The fixed shell 6 has a moving groove 11. There are several moving grooves 11. The pull rod 10 is slidably connected in the moving groove 11. Through the setting of the moving groove 11 and the pull rod 10, the pull rod 10 moves in the moving groove 11 to support the fixed wall 9 and prevent the pull rod 10 from getting stuck, which would make it difficult to open the fixed wall 9.

[0023] Two corresponding pull rods 10 are connected to the fixed wall 9 by a pin. The fixed wall 9 is provided with a sliding groove 12. The two inner walls of the sliding groove 12 are provided with snap-fit ​​grooves 13. The snap-fit ​​grooves 13 are engaged with the limit blocks 14. An electric push rod 15 is provided in the sliding groove 12. One end of the electric push rod 15 is fixedly connected to one side of the limit block 14. The other side of the limit block 14 is fixedly connected to a return spring 16. The other end of the return spring 16 is fixedly connected to one side of the sliding groove 12. By setting the return spring 16, when the limit block 14 needs to be reset after moving in the sliding groove 12, the return spring 16 performs auxiliary reset to prevent the limit block 14 from getting stuck, so as to facilitate the discharge of the cylindrical engine housing.

[0024] A rotary motor 17 is installed inside the fixed wall 9. A connecting gear 18 is fixedly connected to the output end of the rotary motor 17. A limit plate 19 is fixedly connected to one side of the connecting gear 18. Fixed columns 20 are movably connected to both sides of the processing frame 1. A second threaded rod 22 is fixedly connected to the top of the processing frame 1 through a bearing. By setting the fixed column 20 and the second threaded rod 22, rotating the second threaded rod 22 will drive the processing frame 1 to adjust its height within the fixed column 20, making it convenient to adjust the height of the processing frame 1.

[0025] The top end of the second threaded rod 22 is fixedly connected to a rotating handle 23, and the bottom end of the fixed column 20 is fixedly connected to a base 24. The base 24 serves as a support to prevent the fixed column 20 from tipping over.

[0026] The working principle of this utility model is as follows: First, the servo motor 3 is started, and the output end of the servo motor 3 drives the first threaded rod 21 to rotate. The rotation of the first threaded rod 21 drives the connecting column 4 to move. The connecting column 4 drives the sliding column 5 to move. When the sliding column 5 moves, it drives the pull rod 10 to move. The pull rod 10 moves in the moving groove 11. At this time, it opens with the fixed connecting rod 8 as the fixed point. Then, the cylindrical engine housing is put into the fixed wall 9. When the cylindrical engine housing enters the fixed wall 9, the cylindrical engine housing will compress the limiting block 14. The compression inward will pull the pull rod 10 to move the limiting block 14 ... The return spring 16 is activated to prevent the cylindrical engine housing from being fixed to the innermost position. Then, the servo motor 3 is activated to reset and fix the cylindrical engine housing. The rotary motor 17 is activated, which drives the connecting gear 18 and the limiting plate 19 to rotate, limiting the cylindrical engine housing inside the fixed wall 9. The deburring mechanism installed on the processing frame 1 is used to process the cylindrical engine housing. When the cylindrical engine housing needs to be removed, the electric push rod 15 is activated. The electric push rod 15 pushes the limiting block 14 to move forward, and the limiting block 14 pushes the cylindrical engine housing to be discharged.
