On the one hand, many devices cannot ensure that the clamping arms move synchronously, resulting in unstable clamping, and the tire is prone to tilting or slipping, posing a safety hazard. On the other hand, the part of the clamping arm that contacts the tire lacks cushioning and adaptive design, making it difficult to flexibly adjust according to the tire shape and size, which can easily damage the tire and result in poor clamping reliability. Utility Model Content

[0003] This utility model provides an automobile tire transfer clamping device to solve the problem that the contact part between the clamping arm and the tire in the prior art lacks buffering and adaptive design, making it difficult to flexibly adjust according to the tire shape and size.

Detailed Implementation

[0018] To make the technical means, creative features, achieved objectives and functions of this utility model clearer and easier to understand, the utility model will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 3 As shown, this utility model proposes a car tire transfer clamping device, including: a clamping base 1 and a clamping mechanism 2. The clamping base 1 is equipped with the clamping mechanism 2. The clamping mechanism 2 includes: a first clamping arm 21, a second clamping arm 22, a first driving mechanism 23, a second driving mechanism 24, and a synchronous holding mechanism 25. The clamping base 1 is equipped with the first clamping arm 21, the second clamping arm 22, the first driving mechanism 23, and the second driving mechanism 24. The first clamping arm 21 and the second clamping arm 22 can move relative to the clamping base 1 in a horizontal straight line. The first driving mechanism 23... The output end of the first clamping arm 21 is connected to the first clamping arm 21. The first driving mechanism 23 is used to drive the first clamping arm 21 away from or closer to the second clamping arm 22. The output end of the second driving mechanism 24 is connected to the second clamping arm 22. The second driving mechanism 24 is used to drive the second clamping arm 22 away from or closer to the first clamping arm 21. The clamping base 1 is equipped with a synchronous holding mechanism 25. The output end of the synchronous holding mechanism 25 is connected to the first clamping arm 21 and the second clamping arm 22. The synchronous holding mechanism 25 is used to make the first clamping arm 21 and the second clamping arm 22 move away from or closer to each other in a consistent manner.

[0019] The first drive mechanism 23 and the second drive mechanism 24 respectively drive the first clamping arm 21 and the second clamping arm 22 to move relative to the clamping base 1 in a horizontal straight line. When it is necessary to clamp the tire, the first drive mechanism 23 drives the first clamping arm 21 to move closer to the second clamping arm 22, while the second drive mechanism 24 drives the second clamping arm 22 to move closer to the first clamping arm 21. Conversely, the two clamping arms can be moved away from each other, thus releasing the tire. The synchronous holding mechanism 25 plays a key role in this process. Its output end is connected to the first clamping arm 21 and the second clamping arm 22, which can ensure that the two clamping arms move in unison when moving away from or closer to each other, thereby ensuring the accuracy and stability of the clamping action and avoiding unstable or damaged tire clamping due to asynchronous movement of the two clamping arms.

[0020] Both the first clamping arm 21 and the second clamping arm 22 are provided with contact portions 3 that contact the tire to be clamped. The contact portions 3 can rise and fall relative to their respective clamping arms 21 and 22, and are positioned on the clamping arm 21 or 22 by a buffer assembly 4. When clamping tires of different sizes, the contact portions 3 can be adjusted to a suitable position to contact the tire. Simultaneously, the contact portions 3 are positioned on the clamping arms by the buffer assembly 4, which absorbs impact force during clamping, providing a cushioning effect and preventing damage to the tire or contact portions 3 due to excessive clamping force.

[0021] A tire clamping area is formed between the first clamping arm and the second clamping arm. Both the first and second clamping arms include a sliding seat 211, a support arm 212, and a mounting bracket 213. The support arm 212 is connected to the sliding seat 211. The mounting bracket 213 is mounted on the end of the support arm 212 closest to the tire clamping area. A contact part 3 and a buffer assembly 4 are mounted on the end of the mounting bracket 213 closest to the tire clamping area. The sliding seat 211 cooperates with the clamping base 1 to achieve overall sliding of the clamping arm. The support arm 212 is connected to the sliding seat 211, serving to support and transmit force.

[0022] Mounting bracket 213 includes a mounting plate 2131 and a clamping shaft 2132. The mounting plate 2131 is fixedly connected to the support arm 212. The mounting plate 2131 has mounting portions protruding at both ends. The clamping shaft 2132 is rotatably connected to the mounting portions at both ends. Contact portions 3 are sleeved on the clamping shaft 2132. When clamping the tire, multiple contact portions 3 cooperate to clamp the tire. The contact portions 3 can rotate around the clamping shaft 2132 to adapt to the tire's rotation angle for subsequent tire processing.

[0023] The buffer assembly 4 includes a pad 41 and an elastic buffer part 42 (which may be a spring). One end of the elastic buffer part 42 is tightly attached to the mounting bracket 213, and the other end of the elastic buffer part 42 is connected to the pad 41. The pad 41 is tightly attached to the contact part 3. When the tire is clamped, the force on the contact part 3 is transmitted to the elastic buffer part 42, causing it to deform and adjust the angle of the contact part 3 so that it better fits the tire surface, ensuring the stability and adaptability of the clamping. At the same time, it absorbs the impact force and avoids damage to the first clamping arm and the second clamping arm. The specific reason is as follows: When the tire is clamped and placed, the tire impacts the platform to be placed. The tire may cause the first clamping arm and the second clamping arm to deflect upward. In order to mitigate the impact force of the tire on the first clamping arm and the second clamping arm during placement, the elastic buffer part 42 is designed to buffer the impact force, so that the first clamping arm and the second clamping arm will not be subjected to a large impact force, reducing the possibility of the first clamping arm and the second clamping arm being damaged by the impact force, and protecting the first clamping arm and the second clamping arm.

[0024] The synchronous holding mechanism 25 includes a turntable 251 and a transmission belt 252. Two turntables 251 are provided, and both turntables 251 are rotatably connected to the clamping base 1. The transmission belt 252 wraps around the two turntables 251. The two sections of the transmission belt 252 between the two turntables 251 are a first middle section and a second middle section. A first clamping arm is fixed to the first middle section, and a second clamping arm is fixed to the second middle section. When the first drive mechanism 23 and the second drive mechanism 24 drive the first clamping arm and the second clamping arm to move respectively, the transmission action of the transmission belt 252 and the turntables 251 ensures that the two clamping arms move in unison when moving away from or towards each other, thereby achieving stable clamping and release of the tire and ensuring the synchronicity of the clamping process.

[0025] Both the first drive mechanism 23 and the second drive mechanism 24 include a pulling part 231 and a cylinder 232. The cylinder 232 is mounted on the clamping base 1, and the piston rod of the cylinder 232 is fixed to the pulling part 231. The pulling part 231 is hinged to the first clamping arm 21 or the second clamping arm 22. The extension and retraction of the piston rod drives the pulling part 231 to move. The pulling part 231 transmits force to the clamping arm through the hinge point, thereby driving the clamping arm to move in a horizontal straight line to achieve the action of clamping or releasing the tire.

[0026] A drive pin 233 is fixed on the first clamping arm 21 and the second clamping arm 22. The pulling part 231 has a drive hole through which the drive pin 233 passes, and there is a gap between the inner wall of the drive hole and the pulling part 231. When the cylinder 232 is started, its output end, together with the pulling part 231, drives the two clamping arms to move horizontally. The two clamping arms move away or closer synchronously under the drive of the synchronous holding mechanism 25. The gap provides a certain buffer space to accommodate the inconsistency between the pulling distance of the cylinder 232 and the synchronous holding mechanism 25 driving the two clamping arms.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
