A main body of the engine to be processed is first fixed on the support table 110. The bezel to be press-fitted is then slid along the slide 220, passing through the refrigeration passage as the bezel slides along the slide 220. And then utilize cooling piece 210 to cool down the seat circle, make the volume of seat circle diminish under the effect of expend with heat and contract with cold. The pressing end is adjusted to the second position to wait for the seat to be guided out of the slide way 220. The pressing end is then adjusted to a first position, whereby the retainer is press-fitted to the body of the engine using the pressing end. The cylinder cover seat ring press-mounting machine provided by the invention can reduce the seat ring by utilizing low-temperature treatment, can enable the seat ring to be more easily embedded into a mounting position, and reduces the difficulty of press-mounting the seat ring, thereby improving the press-mounting efficiency of the seat ring.
Based on the above solution, the support assembly 100 further includes a frame 120, the support table 110 can move in a horizontal plane relative to the frame 120, and the support table 110 can stay at any position on the sliding track. The main body of the engine is fixed on the support table 110, and the support table 110 moves on a horizontal plane relative to the frame 120, so that the position of the main body of the engine can be adjusted, and the press-fitting operation of the cylinder cover seat ring is facilitated.

On the basis of the above scheme, the supporting assembly 100 further includes a sliding seat 130, a first driving member 140 and a second driving member 150, a first guide rail 121 is laid on the rack 120, the sliding seat 130 is slidably disposed on the first guide rail 121, a second guide rail 131 perpendicular to the first guide rail 121 is laid on the sliding seat 130, the supporting table 110 is slidably disposed on the second guide rail 131, the first driving member 140 drives the sliding seat 130 to slide along the first guide rail 121, and the second driving member 150 drives the supporting table 110 to slide along the second guide rail 131.
It should be noted that the first driving unit 140 drives the sliding base 130 to move along the first guiding rail 121, and the second driving unit 150 drives the supporting base 110 to move along the second guiding rail 131. Since the first rail 121 and the second rail 131 are perpendicular to each other, the support table 110 can move on the horizontal plane. Further, it is understood that the first driving member 140 and the second driving member 150 may be implemented in various embodiments as long as the linear driving is achieved, for example, the first driving member 140 and the second driving member 150 may be a linear motor, a hydraulic cylinder 310, an air cylinder, or the like. The embodiment shown in fig. 1 adopts a screw rod and screw hole matching structure for driving, and details are not repeated herein, and those skilled in the art can select an appropriate implementation manner according to actual needs.
In some embodiments, the hold-down assembly 300 further comprises a hydraulic cylinder 310, the hydraulic cylinder 310 being mounted to the frame 120 with the pressing end located at the piston rod of the hydraulic cylinder 310.

In the above embodiment, the seat ring sliding down from the slide rail 220 is received by the buffer collar 320, and the seat ring is suspended above the engine body because the elastic end of the elastic portion 321 blocks the seat ring and the gravity of the seat ring itself cannot overcome the elastic force of the elastic portion 321. Under the pressure action of the pressing end, the seat ring can overcome the elasticity of the elastic part 321, so that the elastic end retracts, and the seat ring can smoothly pass through the seat ring.
Since the cooling member 210 takes time to effectively cryogenically treat the seat insert, it requires orderly passage of the seat insert into and out of the cooling passage. In some embodiments, the slide way 220 includes the refrigeration section 221, the detention section 222 and the transition section 223, the refrigeration section 221 is located the refrigeration passageway, the detention section 222 both ends dock refrigeration section 221 and transition section 223 respectively, and the detention section 222 is perpendicular to the refrigeration section 221, the cylinder cover seat ring press-fitting machine further includes an adjustment assembly 400, the adjustment assembly 400 includes a detention cylinder 410, the detention cylinder 410 is parallel to the detention section 222, and the piston rod of the detention cylinder 410 has a material pushing end that slides along the detention section 222 to reciprocate, so as to push the seat ring on the detention section 222 to the transition section 223.
In the above embodiment, the seat ring in the cooling section 221 is in the cooling passage, and the cooling member 210 can perform cryogenic treatment on the seat ring. When the seat ring reaches the stagnation section 222, the stagnation section 222 blocks the seat ring from continuing to travel because the stagnation section 222 is perpendicular to the cooling section 221, and the stagnation cylinder 410 can push the seat ring on the stagnation section 222 to a transition, so that whether the seat ring passes through the stagnation section 222 can be controlled by the stagnation cylinder 410. Meanwhile, as the seat rings in the slide way 220 are arranged closely in sequence, only the detention cylinder 410 is operated to block the seat rings from passing through the detention section 222. The seat ring in the cooling section 221 can be made to stay in the cooling passage, so that the residence time of the seat ring in the cooling passage can be controlled.
On the basis of the above scheme, if the posture of the seat ring in the slide way 220 is derived, the seat ring cannot be directly pressed on the engine. The following embodiments can be used to adjust the placing posture of the seat ring, the slide 220 further includes a turning section 224, one end of the turning section 224 is close to the free end of the transition section 223, the adjusting assembly 400 further includes a turning seat 420, a turning cylinder 430 and a material pushing cylinder 440, one end of the turning seat 420 is open to form a material storage cavity 421, the turning seat 420 has a material receiving position enabling the opening thereof to be in butt joint with the transition section 223 and a material discharging position enabling the opening thereof to be in butt joint with the turning section 224, the turning cylinder 430 drives the turning seat 420 to switch between the material receiving position and the material discharging position, and the material pushing cylinder 440 pushes the seat ring in the turning seat 420 to push the turning section 224.
