[0022] In order to further understand the utility model content, characteristics and efficacy of the utility model, the following examples are cited, and the following is described in detail with the help of the drawings.

[0023] The structure of the utility model is described in detail below in combination with the drawings.

[0024] As Figures 1 to 5 The utility model embodiment provides a kind of automobile parts clamp, including guide plate 4, guide plate 4 upper portion is set to the clamping assembly 5 for clamping automobile parts, wherein, clamping assembly 5 includes fixed plate 505, fixed plate 505 is fixed on the upper portion of one side of guide plate 4, guide plate 4 upper portion is also slidably installed with sliding plate 504, sliding plate 504 is screw-connected with first screw 502, first screw 502 is rotatably installed on the upper portion of guide plate 4, sliding plate 504 is driven to approach fixed plate 505 and do clamping action by screw rod, wherein, the inner side of fixed plate 505 and sliding plate 504 is respectively fixedly connected with the protection plate 506 for protecting the outer wall of automobile parts, protection plate 506 is provided with air cavity 509, the strength adjustment of protection plate 506 itself is realized by adjusting internal air pressure by protection plate 506, and protection plate 506 is flexibly arranged.

[0025] The guiding plate 4 is used to support the whole structure, and the upper part of the guiding plate 4 is provided with the fixed plate 505 and the sliding plate 504, so as to form a clamping space, and the sliding plate 504 can slide along the guiding plate 4 under the driving of the first screw rod 502, so as to realize the action of clamping or loosening the automobile parts. Specifically, when the clamping action starts, the first screw rod 502 rotates to drive the sliding plate 504 to slide towards the fixed plate 505. When the sliding plate 504 moves close to the fixed plate 505, the inner side surfaces of the two protection plates 506 gradually approach each other to cover the outer surface of the automobile parts, so as to realize the clamping action.

[0026] The protection plates 506 are respectively fixed to the inner sides of the fixed plate 505 and the sliding plate 504, and the design purpose is to avoid damage to the outer shell of the automobile parts when the clamping assembly 5 clamps. The protection plates 506 are designed to be flexible, and the inner part is provided with an air cavity 509. By adjusting the air pressure of the air cavity 509, the flexibility of the protection plates 506 can be changed. When the air pressure is high, the hardness of the protection plates 506 increases, which is suitable for clamping high-strength parts. When the air pressure is low, the softness of the protection plates 506 increases, which is more suitable for clamping fragile parts.

[0027] Before clamping the automobile parts, the air pressure in the protection plates 506 is adjusted according to the material and pressure-bearing capacity of the parts. Different air pressure values can be selected for different types of parts to ensure that the protection plates 506 are clamped at appropriate flexibility and hardness to avoid damaging the part shell. For example, plastic or thin-walled automobile parts can adjust the air pressure of the air cavity 509 to be low, so that the protection plates 506 are more flexible and avoid pressure concentration on the surface of the parts. For metal parts, the air pressure can be appropriately increased to increase the hardness of the protection plates 506 and provide sufficient clamping force.

[0028] By adjusting the air pressure of the air cavity 509 of the protection plates 506, the clamp can adapt to different automobile parts during clamping, achieving flexible protection of the parts and effectively avoiding damage to the part shell at the clamping position, while improving the applicability and safety.

[0029] In this embodiment, one end of the first screw rod 502 extends through the guiding plate 4 to the outside and is fixedly connected with the knob 501. The knob 501 is internally slidably provided with a slide rod 503 for holding and driving the knob 501 to rotate. The automobile part clamp further comprises a rotating platform 1, and the rotating part of the rotating platform 1 is fixedly connected with a rotating shaft 2 at the upper part. The rotating shaft 2 is fixedly connected with a support disc 3 at the upper part, and the support disc 3 is fixedly connected with the guiding plate 4 at the upper part.

[0030] The design of the slide rod 503 makes it easier for the operator to drive the knob 501, thereby saving labor and rotating the first screw rod 502. Especially when clamping larger or heavier parts, the operator's operation burden is reduced.

[0031] The rotating platform 1 allows the operator to accurately control the angle of the automobile part in the state of clamping the automobile part. This function is suitable for operation scenarios that require different direction and angle inspection, testing or assembly of the clamped part. Through the rotating part of the rotating platform 1, the rotating angle can be fine-tuned during the clamping process, ensuring high-precision control during the machining or inspection process, and avoiding error accumulation caused by repeated picking and placing.

[0032] In this embodiment, each protection plate 506 is fixedly connected with a limiting rod 508 on one side, and the inner side of the fixed plate 505 and the sliding plate 504 is respectively provided with a limiting groove 511, and the two limiting rods 508 are respectively inserted into the limiting grooves 511 of the fixed plate 505 and the sliding plate 504.

[0033] The limiting rod 508 is added to each protection plate 506, which cooperates with the limiting grooves 511 of the fixed plate 505 and the sliding plate 504 to ensure the stable positioning of the protection plate 506 during clamping, avoid falling off after long-term use, and avoid wear or displacement caused by frequent clamping actions

[0034] In this embodiment, the fixed plate 505 is provided with a pressure regulating part 507 on one side for adjusting the air pressure of the air cavity 509 of the protection plate 506. The pressure regulating part 507 includes a gas storage plate 5073, a transmission pipe 5072 is fixedly connected to the through hole of the gas storage plate 5073, and the transmission pipe 5072 is fixedly connected to the fixed plate 505 away from the gas storage plate 5073. A transmission channel 5071 is formed in the fixed plate 505, and a gas hole 510 is formed in the protection plate 506. The transmission pipe 5072 penetrates the transmission channel 5071 and the gas hole 510 and the air cavity 509. A second screw rod 5076 is rotatably installed in the gas storage plate 5073, a screw pipe 5075 is screwed to the outside of the second screw rod 5076, one end of the screw pipe 5075 is fixedly connected with a piston plate 5074, the piston plate 5074 is slidably installed in the gas storage plate 5073, one end of the second screw rod 5076 extends to the outside through the gas storage plate 5073 and is fixedly connected with a rotating disc 5077, and the piston plate 5074 is controlled by the rotating disc 5077 to slide in the gas storage plate 5073 to adjust the pressure of the air cavity 509.

[0035] The pressure regulating part 507 is used for adjusting the air pressure in the air cavity 509 of the protection plate 506, and the pressure regulating part 507 includes a gas storage plate 5073 and a transmission pipe 5072. The gas storage plate 5073 is connected to the transmission pipe 5072 through the through hole, and is connected to the air cavity 509 of the protection plate 506 through the transmission channel 5071. The adjustment of the air pressure can directly act on the air cavity 509 of the protection plate 506.

[0036] Specifically, when the rotating disc 5077 rotates to drive the second screw rod 5076, the piston plate 5074 moves inside the gas storage plate 5073, changing the gas pressure inside the gas storage plate 5073. If the piston plate 5074 moves towards the transmission pipe 5072, the gas inside the gas storage plate 5073 is compressed, increasing the pressure in the gas cavity 509 through the transmission pipe 5072 and the transmission channel 5071, increasing the hardness of the protection plate 506, and being suitable for clamping high-strength parts. If the piston plate 5074 moves in the opposite direction, the gas pressure in the gas cavity 509 will decrease, increasing the flexibility of the protection plate 506, which is more suitable for clamping fragile parts.

[0037] By controlling the position of the piston plate 5074 through the rotating disc 5077, the gas pressure in the gas cavity 509 can be finely adjusted to meet the needs of different clamping forces. This structure can ensure that the hardness of the protection plate 506 matches the material properties of the parts during use, improving the safety and adaptability of the clamping process, so that the protection plate 506 has appropriate hardness during clamping, meeting the clamping needs of different automobile parts, and effectively reducing the risk of damage during clamping.

[0038] The working principle of the utility model:

[0039] When the clamping action starts, the first screw rod 502 rotates to drive the sliding plate 504 to slide towards the fixed plate 505. When the sliding plate 504 moves close to the fixed plate 505, the inner surfaces of the two protection plates 506 gradually approach each other, covering the outer surface of the automobile parts, and realizing the clamping action. The protection plates 506 are fixed on the inner sides of the fixed plate 505 and the sliding plate 504, respectively, and the design purpose is to avoid damage to the automobile part shell during the clamping action of the clamping assembly 5. The protection plate 506 is designed to be flexible, with a gas cavity 509 inside. By adjusting the gas pressure of the gas cavity 509, the flexibility of the protection plate 506 can be changed. When the gas pressure is high, the hardness of the protection plate 506 increases, which is suitable for clamping high-strength parts. When the gas pressure is low, the softness of the protection plate 506 increases, which is more suitable for clamping fragile parts.
