The central axis of the clamping wheel 44 forms a 10-20° angle with the central axis of the polishing wheel 42. The clamping wheel 44 is located in front of the polishing wheel 42, and the circumferences of the clamping wheel 44 and the polishing wheel 42 are opposite each other, with their minimum distance being less than the outer diameter of the middle outer circle 7. The support plate adjustment mechanism 45 is located to the right of the feeding cylinder 33 and between the polishing wheel 42 and the clamping wheel 44. The laser temperature measuring device 43 is located above the support plate adjustment mechanism 45. The laser temperature measuring device 43 and the servo feed mechanism 41 are simultaneously connected to the control box 6.

[0055] All electrical components in the intermediate cylindrical grinding machine are connected to control box 6;

[0056] The intermediate external cylindrical grinding machine of this utility model can perform automatic grinding. The specific process is as follows:

[0057] (1) Artificially put the middle outer circle 7 into the feeding box 22;

[0058] (2) The control box 6 controls the feeding cylinder 21 to push the middle outer circle 7 in the feeding box 22 upward until the middle outer circle 7 rolls into the trough 36 of the feeding mechanism 3, and the position is random;

[0059] (3) The inductive switch a 34 monitors the state of the middle outer circle 7 in the trough 36 in real time. Once it detects the presence of the middle outer circle 7, it immediately sends a signal to the control box 6, which controls the feeding cylinder 21 to reset, and at the same time controls the pushing cylinder 31 to move, driving the pushing rod 35 to push the middle outer circle 7 to the position of the clamping cylinder 32. After the inductive switch b senses that the middle outer circle 7 reaches the clamping area of the clamping cylinder 32, it sends a signal to the control box 6, which controls the clamping cylinder 32 to clamp the middle outer circle 7;

[0060] (4) After the clamping cylinder 32 clamps the middle outer circle 7, it sends a signal to the control box 6, which controls the pushing cylinder 31 to reset, and at the same time controls the feeding cylinder 33 to send the middle outer circle 7 clamped by the clamping cylinder 32 to the support plate adjusting mechanism 45;

[0061] (5) After the feeding cylinder 33 finishes work, it sends a signal to the control box 6, which controls the clamping cylinder 32 and the feeding cylinder 33 to reset, and at the same time controls the polishing wheel driving motor 46, the tight wheel driving motor 47, the laser temperature measuring device 43, the servo feeding mechanism 41, the dust suction system, and the flat belt driving motor 55 to start;

[0062] The polishing wheel driving motor 46 drives the polishing wheel 42 to rotate around its central axis, and the tight wheel driving motor 47 drives the tight wheel 44 to rotate around its central axis, together realizing the grinding of the middle outer circle 7;

[0063] The laser temperature measuring device 43 monitors the temperature T of the ground area of the middle outer circle 7 in real time. After collecting n Ts, it sends them to the control box 6. The control box 6 calculates the average value T* of the n Ts and compares it with the threshold τ. n is 3-5, and τ is 55-65℃. If T* is higher than τ, the control box 6 controls the polishing wheel 42 to retreat 0.05-0.5mm through the servo feeding mechanism 41, and vice versa;

[0064] In this process, due to the 10-20° angle between the central axis of the tight wheel 44 and the central axis of the polishing wheel 42, the ground middle outer circle 7 will automatically move to the flat belt 52;

[0065] The flat belt driving motor 55 drives the flat belt 52, and the middle section outer circle 7 after grinding is driven by the flat belt 52 to move to the right until it is blocked by the discharging baffle 53, and then the middle section outer circle 7 falls off the flat belt 52 and enters the discharging box 51, and thus the whole grinding process is completed.
