[0031] like Figures 1 to 4As shown, the embodiment of the present invention provides a car seat cushion processing and punching device, including a punching machine 1 and a limiting component 3, and also includes a placing table. When punching the car seat cushion, the car seat cushion needs to be placed on the placing table, and then the car seat cushion is punched with the help of a punching motor and a punching cylinder 2. This is the prior art. A connecting clamp 4 is provided inside the punching machine 1, and a punching cylinder 2 is fixedly sleeved inside the connecting clamp 4. The limiting component 3 includes a connecting sleeve 301, which is installed at the bottom of the connecting clamp 4. A plurality of positioning arc plates 302 are provided on the top of the connecting sleeve 301. A groove 306 is provided inside the positioning arc plate 302, and an elastic pressure plate 303 is provided inside the groove 306. A circular pressure plate 304 is provided at one end of the elastic pressure plate 303, and a plurality of mounting grooves 309 are provided inside the circular pressure plate 304. A limiting arc plate 310 is provided inside the mounting groove 309. The shape of the elastic pressure plate 303 is an arc-shaped elastic structure. A weakening groove 305 is provided inside the elastic pressure plate 303. The shape of the positioning arc plate 302 is U-shaped and is a circular arc plate. The positioning arc plate 302 is made of metal. One end of the elastic pressure plate 303 contacts the inner wall of the circular pressure plate 304. The shape of the circular pressure plate 304 is circular. The connecting sleeve 301, the positioning arc plate 302 and the elastic pressure plate 303 are an integrated structure. The positioning arc plates 302 are arranged circumferentially at the bottom of the connecting sleeve 301. The circular pressure plate 304 and the limiting arc plate 310 are provided at the bottom of the connecting sleeve 301. It is an integrated structure, and the shape of the arc plate 310 is an arc-shaped elastic structure. By setting the limiting component 3, the elastic pressure plate 303 is connected to the connecting sleeve 301 through the positioning arc plate 302. The elastic pressure plate 303 is set inside the internal groove 306 of the positioning arc plate 302. The shape of the elastic pressure plate 303 is an arc-shaped elastic structure. When the punching cylinder 2 punches holes in the seat cushion, the elasticity of the elastic pressure plate 303 is utilized, and with the help of the circular pressure plate 304, the seat cushion can be pressed down in advance to make the seat cushion deform in advance, so as to avoid the uneven punching edge caused by the deformation of the seat cushion, which affects the quality of the seat cushion. The arc plates 310 are arranged circumferentially on the inner wall of the circular pressure plate 304, and the shape of the arc plates 310 is limited. It is an arc-shaped elastic structure. When the circular pressing plate 304 is used to press the seat cushion, the limiting arc plate 310 is embedded in the seat cushion, which can further limit the position of the seat cushion to avoid the seat cushion position deviation during the punching process, causing the hole position to deviate from the predetermined marking point, thereby affecting the punching accuracy. The punching position of the seat cushion can be limited to avoid the seat cushion from moving during the punching process, causing the punching position to deviate from the predetermined marking point, thereby affecting the accuracy of the product. Moreover, during the punching process of the seat cushion, the seat cushion is pressed in advance to avoid deformation of the seat cushion during the punching process, resulting in uneven punching edges, burrs or tears, and different hole sizes, thereby affecting the quality of the seat cushion.

[0032] like Figure 4As shown, a limiting slide bar 308 is provided on the outer wall of the elastic pressure plate 303, and a limiting slide groove 307 that is adapted to the shape of the limiting slide bar 308 is provided on the inner wall of the groove 306. By setting the limiting slide groove 307 and the limiting slide bar 308, the limiting slide bar 308 is provided on the outer wall of the elastic pressure plate 303 and has a mirror structure. When in use, the limiting slide bar 308 is slidably sleeved into the limiting slide groove 307 that is adapted to the shape of the limiting slide bar 308. When the elastic pressure plate 303 is deformed, the movement process of the elastic pressure plate 303 is limited to avoid excessive deformation of the elastic pressure plate 303 and damage to the elastic pressure plate 303, and to avoid the elastic pressure plate 303 from deforming inward and affecting the efficiency of the punching tube 2 in punching holes in the seat cushion.

[0033] like Figure 2 and Figure 3 As shown, a plurality of connecting arc plates 6 are provided on the top of the connecting sleeve 301, and a connecting card groove 5 adapted to the shape of the connecting arc plate 6 is provided on the outer wall of the connecting clamp 4, and a dial plate 7 is provided at one end of the connecting arc plate 6. The connecting arc plate 6 and the dial plate 7 are an integrated structure, and the shape of the connecting arc plate 6 is an arc-shaped curved surface elastic structure. By setting the connecting arc plate 6, the connecting arc plate 6 is set on the top of the connecting sleeve 301, and multiple connecting arc plates 6 are arranged circumferentially on the top of the connecting sleeve 301. The shape of the connecting arc plate 6 is an arc-shaped curved surface elastic structure. During installation, the dial plate 7 is dialed to fix the connecting arc plate 6 into the inside of the connecting card groove 5 adapted to the shape of the connecting arc plate 6, so as to facilitate the installation of the limiting component 3 to the outside of the connecting clamp 4.

[0034] The working principle of the technical solution provided by the present invention is as follows: when in use, the car seat cushion to be processed is first placed on the placement table, and then the connecting arc plate 6 and the connecting slot 5 are fixedly connected to fix the limiting component 3 to the outer wall of the connecting clamp 4, and the positioning arc plate 302 is sleeved on the outer wall of the punching cylinder 2. Then, in the process of punching the seat cushion using the punching cylinder 2, the limiting component 3 is driven to move downward, so that the positioning arc plate 302 is inserted into the seat cushion to limit the position where the seat cushion needs to be punched. At the same time, the elastic pressure plate 303 and the circular pressure plate 304 are used to press the seat cushion in advance and press the car seat cushion on the placement table to avoid deformation of the seat cushion during the punching process, which may cause uneven punching edges, burrs or tearing, and uneven hole sizes, affecting the quality of the seat cushion. At the same time, the limiting arc plate 310 can be used to further limit the seat cushion to avoid deviation of the position of the seat cushion during the punching process, causing the position of the hole to deviate from the predetermined marking point, thereby affecting the accuracy of the product.
