[0001] The utility model belongs to the field of automobile parts assembly, and in particular relates to an auxiliary clamping device for frame welding. Background Art

[0002] When welding a frame, a stable welding environment needs to be provided to prevent external factors from affecting the welding efficiency. In the prior art, the positioning of the frame is mainly done manually, and the process relies on the proficiency of the employees to balance the welding quality of the frame. The existing frame welding fixture is prone to poor welding quality due to the unstable welding environment, and the delicate frame fixing process will affect the operation rhythm and reduce production efficiency.

[0003] Patent application number CN204430658U A sub-frame bracket welding fixture includes a fixture base, a clamping mechanism and a positioning mechanism, the fixture base includes a fixture base, a first fixture base located at the lower left of the fixture base and a second fixture base located at the lower right of the fixture base, the clamping mechanism includes a first clamp located at the upper left of the fixture base, a second clamp located at the upper right of the fixture base, a first clamp welded on the first clamp and a second clamp welded on the second clamp, the positioning mechanism includes a first positioning pin, a second positioning pin, a third positioning pin, a fourth positioning pin and a fifth positioning pin, the first positioning pin and the second positioning pin are located on the first fixture base, the second positioning pin is located on the first clamp, the third positioning pin is located on the second fixture base, and the fourth positioning pin and the fifth positioning pin are located on the second clamp. The frame is fixed by only a small number of positioning pins and clamps. During the frame welding process, the frame may be unstable, thereby affecting the welding efficiency. Therefore, it is urgent for those skilled in the art to solve the above technical problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an auxiliary clamping device for frame welding in view of the deficiencies of the above-mentioned prior art. The auxiliary clamping device for frame welding fixes the frame above the base through a support member, a clamping arm and a positioning member, thereby providing a stable working environment for manual welding.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] An auxiliary clamping device for frame welding comprises a base, feet, a support, a clamping arm and a positioning member, wherein five feet are arranged at the bottom of the base, the positioning member is used to fix the frame on the base, the support member is used to support the frame to prevent the frame from contacting the base, a plurality of support members and a plurality of positioning members are arranged on the base, and a plurality of clamping arms are also arranged at the head and tail ends of the base.

[0007] Furthermore, the support member is L-shaped as a whole, and the bottom of the support member is connected to the base by bolts; the upper part of the support member is provided with a connecting member, a buffer member and a limit member, the connecting member is used to connect the support member, the buffer member and the limit member, and the connecting member fixes the buffer member and the limit member to the upper part of the support member by screws.

[0008] The L-shaped support design, combined with the connection method of bolts and the base, can form a stable mechanical structure, ensuring that it can withstand large loads without deformation or failure during the welding process, and ensuring that the frame is firmly clamped. The setting of the buffer helps to absorb and disperse the vibration and impact force generated during the welding process, reduce potential damage to the frame and the device itself, and improve welding quality and equipment life. The function of the connector is to integrate the support, buffer and limiter together. By fixing with screws, the position of each component can be fine-tuned according to actual welding requirements to adapt to frames of different sizes and shapes. The limiter can ensure that the frame remains in the set position during welding, avoids position deviation during welding, and thus improves welding accuracy and product quality. This design improves the functionality and durability of the frame welding auxiliary clamping device, optimizes the welding operation process, and ensures the quality of the final product.

[0009] Furthermore, the contact surface between the buffer and the frame is arc-shaped, and the buffer is made of rubber, and the limiting member is also an L-shaped structure made of rubber.

[0010] Rubber materials have good elasticity and buffering properties. When the frame is impacted or vibrated, the rubber buffer can effectively absorb and disperse these forces, thereby protecting the frame from damage. At the same time, it also reduces noise and vibration transmission and improves the stability of the welding process. The arc contact surface design fits the contour of the frame better, can evenly disperse the pressure, and prevent local stress from being excessive and causing deformation or damage to the frame. At the same time, it also enhances the friction between the two, making the frame more stable during the welding process. The limiter adopts a rubber L-shaped structure, which not only has certain flexibility and resilience, but can also constrain the position of the frame while avoiding wear or scratches caused by hard contact. In addition, the rubber material can also play a certain degree of sound absorption and noise reduction. The rubber material has good wear resistance and anti-aging performance, and can still maintain good buffering and limiting effects under long-term use, thereby extending the service life of the device. This design not only achieves effective fixation and protection of the frame, but also takes into account the convenience and durability of the equipment.

[0011] Furthermore, the clamping arm comprises an operating rod, a clamping claw and a clamping arm bracket, the clamping arm bracket is fixed to the base by bolts, the clamping claw is arranged on the upper part of the clamping arm bracket, and the operating rod is arranged on the outer wall of the clamping arm.

[0012] The clamping arm bracket is fixed to the base by bolts, so that it can be flexibly adjusted according to different frame sizes and welding parts to achieve accurate positioning and effective clamping of the frame. The operating lever is set on the outer wall of the clamping arm. The staff can easily control the opening and closing of the clamping jaws through the operating lever without direct contact with high temperature or dangerous areas, which not only ensures the safety of the operator but also improves work efficiency. The clamping jaws are set on the upper part of the clamping arm bracket, which can clamp the frame in the vertical direction to prevent the frame from shaking or slipping during welding, thereby ensuring the stability and quality of the welding work. The clamping arm bracket is fixed by bolts, which makes the entire clamping mechanism have high structural strength and durability, and can withstand long-term high-intensity workloads. If the clamping arm part fails or accessories need to be replaced, it is easy to disassemble and repair due to the non-permanent connection method of bolt fixing, which greatly reduces the maintenance cost and difficulty.

[0013] Further, the positioning member is arranged in the middle of the bottom, and the positioning member includes a support foot, a driving cylinder, a first positioning clamp and a second positioning clamp. The support foot is connected to the base by bolts, and the driving cylinder is arranged on the base in contact with the support foot. The first positioning clamp is arranged on the upper part of the support foot, and the first positioning clamp is connected to the support foot by screws, and the second positioning clamp is connected to the driving cylinder by screws.

[0014] The locating piece is arranged in the middle of the bottom, which can better center the frame and ensure that the frame is placed in the center during welding, thereby improving the welding accuracy and consistency of the finished product. The setting of the driving cylinder realizes automatic control. Through the air pressure drive, the position of the first locating clamp and the second locating clamp can be adjusted quickly and accurately, which greatly improves the work efficiency and positioning accuracy. The support feet are connected to the base by bolts to form a stable basic support structure, ensuring that the entire device remains stable when strong clamping or facing a large impact. The first locating clamp and the second locating clamp are connected to the support feet and the driving cylinder respectively by screws, which can move independently or synchronously to adapt to frames of different shapes and sizes, increasing the flexibility and adaptability of clamping. Since all components are connected by bolts or screws, daily inspection, maintenance and replacement are convenient, reducing the complexity and cost of equipment maintenance.

[0015] Furthermore, the first positioning clamp and the second positioning clamp are both made of rubber, and the first positioning clamp and the second positioning clamp are square in shape as a whole, and the driving cylinder drives the second positioning clamp to move in the vertical direction along the supporting leg.

[0016] The rubber material has excellent elasticity and buffering properties, which can effectively prevent scratches or damage to the surface of the frame when clamping it, and provides good protection for precision or vulnerable parts. The square design makes the contact area between the positioning clamp and the frame larger, increases the friction, and thus enhances the clamping stability. Even if the frame is impacted during welding, it can maintain a stable position. The driving cylinder can accurately control the movement of the second positioning clamp, so that the two positioning clamps can be dynamically adjusted according to the specific shape and size of the frame to achieve more accurate positioning and clamping. The rubber material can not only absorb part of the vibration energy and reduce noise, but also reduce the stress concentration caused by the clamping process, and further protect the structural integrity of the frame and the quality of the weld. The rubber material has good wear resistance and anti-aging properties, is durable, and is suitable for long-term use in industrial environments.

[0017] The utility model has the following beneficial effects:

[0018] The utility model is provided with a plurality of supporting members, a plurality of clamping arms and a plurality of positioning members to provide support for the frame to be welded, and a plurality of groups of supporting members and positioning members are provided on the base, which can be flexibly adjusted according to the actual shape and size of the frame to meet the welding requirements of frames of different specifications. The clamping arms provided at the head and tail ends of the base can firmly clamp the frame from both ends, further enhancing the stability during the welding process, ensuring that the frame is always kept in the best posture during the welding process, which is conducive to completing the welding operation with high quality.

[0019] The first positioning clamp on the positioning member cooperates with the second positioning clamp on the driving cylinder to further position the frame. The second positioning clamp can be separated from the first positioning clamp by simply starting the driving cylinder. The operation is simple and convenient.

[0020] An operating lever is provided on the clamping arm. The staff only needs to rotate the operating lever to fix and separate the clamping claw and the clamping arm bracket. The clamping claw and the frame can be fixed and released by controlling the clamping claw through the operating lever. The overall operation is simple. BRIEF DESCRIPTION OF THE DRAWINGS
