[0025] The clamping assembly comprises clamping plates 9, which are directly used for clamping the sound insulation pads, are adapted to sound insulation pads of different sizes through relative movement, and realize fixation of the sound insulation pads. The lower surfaces of the clamping plates 9 are slidingly connected to the upper surface of the top plate 8. The lower surface of each clamping plate 9 is fixedly connected with a connecting rod 10. The lower surface of the connecting rod 10 is fixedly connected with a sliding plate two 11, which moves under the pushing of the cylinder two 22, drives the synchronous movement of the connecting block two 14, the connecting rod 10, the clamping plate 9, the connecting block one 12, the rack 15 and other components connected thereto, and guarantees the stability and accuracy of the movement of the sliding plate two 11. The lower surface of the sliding plate two 11 is fixedly connected with the connecting block two 14, which is connected with the sliding plate two 11 and slides along the slide rail 13. The outer wall of the connecting block two 14 is slidingly connected with the slide rail 13, which provides a sliding track for the connecting block two 14 and limits the movement direction thereof. The lower surface of the connecting block one 12 is fixedly connected with the rack 15, which is engaged with the gear 16 and moves under the driving of the connecting block one 12. Through cooperation with the gear 16, the relative movement of the two clamping plates 9 is realized, the clamping action on sound insulation pads of different sizes is completed, and the outer wall of the rack 15 is engaged with the gear 16. The inner wall of the base 2 is fixedly connected with the cylinder two 22, which is used for providing power to push the sliding plate two 11 to move. The output end of the cylinder two 22 is fixedly connected to the outer wall of the sliding plate two 11. The upper surface of the base 2 is fixedly connected with the slide rod 3. The upper surface of the slide rod 3 is fixedly connected with the support plate 4. The upper surface of the support plate 4 is fixedly connected with the cylinder one 6, which provides power in the hot-pressing link to push the sliding plate one 5 to move downward. The output end of the cylinder one 6 is fixedly connected with the sliding plate one 5. The outer wall of the slide rod 3 is slidingly connected with the sliding sleeve 7, and the outer wall of the sliding sleeve 7 is fixedly connected to the inner wall of the sliding plate one 5. The sliding plate one 5 is internally provided with a buffer assembly.
[0026] Specifically, when the sound insulation pad is clamped, the cylinder two 22 starts to work, and the pushing force output by the cylinder two 22 directly pushes the sliding plate two 11 to move. The connecting block two 14 is fixedly connected with the sliding plate two 11, so when the sliding plate two 11 moves, the connecting block two 14 stably slides along the slide rail 13. The clamping plate 9 is connected with the sliding plate two 11 through the connecting rod 10, and then moves synchronously with the sliding plate two 11. When the connecting block two 14 moves, the rack 15 connected thereto moves. Since the rack 15 and the gear 16 are engaged with each other, the two clamping plates 9 move relatively, so that stable clamping of sound insulation pads of different sizes is realized.
[0027] Referring to Figure 1 - Figure 3The buffer assembly comprises a spring 18 fixedly connected at one end to the upper surface of the sliding plate 5 and at the other end to a limiting plate 17, which limits the movement range of the sliding rod 21 to avoid excessive expansion and contraction of the spring 18 and the spring 20, thereby ensuring the stability and reliability of the hot pressing process.

The lower surface of the sliding rod 21 is fixedly connected with a hot pressing plate 19, and the upper surface of the hot pressing plate 19 is fixedly connected with the spring 20. The spring 18 and the spring 20 play a buffering role during the pressing process of the hot pressing plate 19, absorbing and dispersing the impact force generated when the hot pressing plate 19 is pressed down, so that the hot pressing plate 19 can uniformly and stably exert pressure on the sound insulation pad, avoiding damage to the sound insulation pad due to uneven or excessive pressure.

The outer wall of the spring 20 is slidingly connected to the inner wall of the sliding plate 1, and the spring 20 is used to buffer the hot pressing plate 19. The outer wall of the sliding rod 3 is slidingly connected to the inner wall of the sliding plate 1, and the sliding rod 3 is used to guide the sliding plate 1.
[0028] Specifically, the cylinder 6 starts to work, and its output end pushes the sliding plate 5 to move downward. During the pressing process of the sliding plate 5, the spring 18 and the spring 20 play a buffering role. With the pressing of the sliding plate 5, the spring 18 and the spring 20 are squeezed and expanded, effectively buffering the impact force generated when the hot pressing plate 19 is pressed down, so that the hot pressing plate 19 can act on the sound insulation pad with stable and uniform pressure. One end of the sliding rod 21 is connected to the hot pressing plate 19, and the other end penetrates the sliding plate 5 and is connected to the limiting plate 17. The sliding rod 21 provides a guide for the expansion and contraction of the spring 18 and the spring 20, ensuring that the spring 18 and the spring 20 maintain stable movement during the expansion and contraction process, and limiting the downward stroke of the hot pressing plate 19. The limiting plate 17 limits the movement range of the sliding rod 21 to avoid excessive expansion and contraction of the spring 18 and the spring 20, thereby ensuring the stability and reliability of the hot pressing process and effectively improving the quality and efficiency of the hot pressing of the automobile sound insulation pad.
[0029] Working principle: when the automobile sound insulation pad hot pressing machine needs to be used, firstly, the sliding plate two 11 is pushed to move by the air cylinder two 22, the movement of the sliding plate two 11 drives the connecting block two 14 to slide along the slide rail 13, and drives the clamping plate 9 to move, when the connecting block two 14 moves, the rack 15 moves under the cooperation of the gear 16, at this time, the two clamping plates 9 move relatively, different sizes of sound insulation pads are clamped, then, the air cylinder one 6 is started, the output end of the air cylinder one 6 pushes the sliding plate one 5 to press down, in the process, the hot pressing plate 19 can stably press down the sound insulation pad through the expansion and contraction of the spring one 18 and the spring two 20, the buffering effect is achieved, at the same time, the expansion and contraction of the spring one 18 and the spring two 20 can be guided through the sliding rod 21, the hot pressing plate 19 can also be limited to press down, finally, the sliding rod 21 is limited by the limiting plate 17, so that the spring one 18 and the spring two 20 are prevented from overexpanding.
[0030] Finally, it should be noted that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. within the spirit and principles of the utility model, should be included in the protection scope of the utility model.
