[0019] In this embodiment, as Figure 1 and Figure 2 As shown, a car seat steel wire frame clamp includes a base plate 1 and a pressure plate 2. The pressure plate 2 is connected to the base plate 1 through a telescopic member 21. A serpentine clamping assembly 3 clamps the steel wire frame placed in the car seat at multiple points to disperse the stress on the steel wire frame. A seat support assembly 4 is used to fix the car seat to prevent the car seat from moving during processing. The serpentine clamping assembly 3 includes: a first hinge arm 31, which is connected to the pressure plate 2 via a connector 32; a second hinge arm 33, which is connected to the first hinge arm 31 via a pin 331, and the pin 331 is connected to the first hinge arm 31 via a positioning pin 332; and a flexible pressure plate 34, which is located at the end of the second hinge arm 33 away from the first hinge arm 31, and the top end of the flexible pressure plate 34 is connected to the second hinge arm 33 via a connecting rod 341.

[0020] Thus, the second hinge arm 33 in the first hinge arm 31 is rotated by the pin 331, and an angle appears between the first hinge arm 31 and the second hinge arm 33. Then, the positioning pin 332 is used to press against the pin 331 in the first hinge arm 31 to fix the first hinge arm 31 and the second hinge arm 33. Then, the first hinge arm 31 and the second hinge arm 33 bend, so as to change the position of the flexible pressure plate 34, which facilitates flexible pressing of different steel wire skeletons and disperses the stress on the steel wire skeleton.

[0021] Specifically, the base plate 1 is connected to the pressure plate 2 via the telescopic member 21. The output end of the telescopic member 21 drives the pressure plate 2 to move. The base plate 1 and the pressure plate 2 are arranged in parallel. The base plate 1 supports the overall mechanism. During the processing of the car seat, it is located between the base plate 1 and the pressure plate 2. The second hinge arm 33 rotates in the first hinge arm 31 via the pin 331. The first hinge arm 31 and the pressure plate 2 are designed to be detachable, which is convenient for selective use according to needs. The outer wall of the positioning pin 332 is threaded. The positioning pin 332 is used to abut against the pin 331 to fix the included angle between the second hinge arm 33 and the first hinge arm 31. The design of the flexible pressure plate 34 provides multi-point abutment to the steel wire skeleton.

[0022] In some embodiments, such as Figure 2 As shown, the connector 32 includes: multiple pads 321, which are symmetrically distributed based on the pressure plate 2; a prismatic rod 322, the bottom end of which is connected to the pads 321, and a screw 322a is fixedly connected to the top end of the prismatic rod 322, with a nut 322b threadedly connected to the outer periphery of the screw 322a; and a sleeve 323, which has a prismatic groove 323a that is adapted to the prismatic rod 322, and the outer periphery of the sleeve 323 is connected to the first hinge arm 31.

[0023] Specifically, there are ten pads 321, which are divided into two groups and symmetrically distributed based on the pressure plate 2. (The actual number of pads 321 used can be selectively installed according to the needs.) The design of the prismatic rod 322 facilitates the determination of the included angle between the first hinge arm 31 and the pressure plate 2, and prevents the sleeve 323 from rotating arbitrarily. The design of the screw 322a and nut 322b is used to constrain the position of the sleeve 323 on the outer wall of the prismatic rod 322. The number of edges of the prismatic groove 323a is consistent with the number of edges of the prismatic rod 322.

[0024] In some embodiments, such as Figure 2 As shown, the rhomboid rod 322 is an octagonal prism; Specifically, the prismatic rod 322 is designed as an octagonal prism, which facilitates the sleeve 323 to drive the first hinge arm 31 to make multi-angle adjustments. In addition, the outer wall of the prismatic rod 322 can also be processed into four edges, six edges, etc., depending on the usage requirements.

[0025] In some embodiments, such as Figure 3 As shown, the seat support assembly 4 includes: a bearing shell 41, the bottom end of which is connected to the base plate 1, and a groove 41a is machined in the bearing shell 41; two clamping plates 42, both of which are slidably connected to the groove 41a; and a driving member 43, which is used to drive the two clamping plates 42 to move towards each other.

[0026] Specifically, the top of the carrier shell 41 is used to place the car seat, and the slide 41a is designed to constrain the lateral movement of the two clamps 42, which extend to the top of the carrier shell 41 according to a preset height.

[0027] In some embodiments, such as Figure 4 As shown, the driving component 43 includes: a double-threaded rod 431, which is connected to the bearing housing 41 via a bearing, and a slide block 432 is threadedly connected to the outer periphery of the double-threaded rod 431, with the outer periphery of the slide block 432 fixedly connected to the clamping plate 42; and a motor 433, the output end of which is connected to the double-threaded rod 431, and the bottom end of which is connected to the bearing housing 41 via a motor base 433a. Specifically, the slide 432 is designed with two internal threads connected to the double-threaded rod 431. The slide 432 is used to drive the clamping plate 42 to move. The motor 433 is connected to the double-threaded rod 431 through a coupling. The motor 433 is controlled by an external PLC. The motor base 433a is used to support the motor 433. The two clamping plates 42 can move towards each other to clamp the car seat and drive the car seat to move towards the middle position of the carrier shell 41.

[0028] In some embodiments, such as Figure 2 As shown, the flexible pressure plate 34 is made of rubber material; Specifically, the flexible pressure plate 34 is designed with rubber material, which utilizes the plasticity of rubber material to prevent excessive resistance from causing deformation of the steel wire skeleton.

[0029] In some embodiments, such as Figure 5 As shown, a guide rod 22 is slidably connected in the pressure plate 2, and the bottom end of the guide rod 22 is connected to the base plate 1; Specifically, the pressure plate 2 is machined with through holes that are compatible with the guide rod 22, and the design of the guide rod 22 constrains the vertical movement of the pressure plate 2.

[0030] In some embodiments, such as Figure 5 As shown, the telescopic component 21 is an electro-hydraulic push rod.

[0031] Specifically, the telescopic component 21 adopts an electro-hydraulic push rod design, which facilitates connection with an external PLC and allows the external PLC to control the lifting and lowering of the electro-hydraulic push rod.

[0032] The working principle of this application is illustrated below with a preferred embodiment: The stamped car seat frame is placed flat on top of the bearing shell 41. Then the motor 433 is started. The output end of the motor 433 drives the double-threaded rod 431 to rotate in the bearing shell 41 through the coupling. As the double-threaded rod 431 rotates, it drives the two slide blocks 432 to move. The slide blocks 432 drive the two clamping plates 42 to move towards each other in the slide groove 41a to clamp the car seat frame. The steel wire skeleton is placed in the groove of the car seat frame, and then the telescopic component 21 is activated (the telescopic component 21 is controlled by an external PLC). The output end of the telescopic component 21 drives the pressure plate 2 to move downward. When the pressure plate 2 moves downward along the outer wall of the guide rod 22, it drives the flexible pressure plate 34 to press against the steel wire skeleton to fix the position of the steel wire skeleton in the car seat frame for welding. When it is necessary to change the contact position of the flexible pressure plate 34, rotate the nut 322b to separate it from the screw 322a, move the sleeve 323 upward to the position of the screw 322a, then rotate the sleeve 323 so that an angle is formed between the first hinge arm 31 and the pressure plate 2, and then move it downward along the outer wall of the prismatic rod 322 through the prismatic groove 323a. The sleeve 323 is reinserted into the prismatic rod 322, and the bottom end of the sleeve 323 contacts the pad 321. Tighten the nut 322b to fix the position of the sleeve 323. Then, through... The second hinge arm 33 in the first hinge arm 31 is rotated by the pivot pin 331, and an angle appears between the first hinge arm 31 and the second hinge arm 33. Then, the positioning pin 332 is used to press against the pivot pin 331 in the first hinge arm 31 to fix the first hinge arm 31 and the second hinge arm 33. As a result, the first hinge arm 31 and the pressure plate 2, as well as the first hinge arm 31 and the second hinge arm 33, are bent to change the position of the flexible pressure plate 34, so as to facilitate the pressing of different steel wire skeletons.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
