[0002] With the rapid development of the automobile industry and increasingly fierce market competition, in order to meet the ever-higher requirements of consumers for automobile quality, each automobile manufacturer is constantly seeking technological innovation and process improvement. Against this background, the assembly accuracy and efficiency in the body manufacturing process become particularly important. The pre-assembly of the vehicle side panel and the lower floor is one of the key links in the entire vehicle body assembly process, and its assembly accuracy directly affects the quality and performance of the whole vehicle.

[0003] Currently, mainstream automobile manufacturers usually pre-assemble the buckle on the outer panel of the side panel wheelhouse with the lower floor. In this process, the buckle used on the side panel wheelhouse is punched out by a stamping die and then welded through multiple processes. However, during transportation and subsequent processing, the angle of the buckle is prone to deviation, resulting in the problem of buckle angle deviation during pre-assembly. This deviation not only increases the probability of pre-assembly failure but also may cause the side panel to fall off and be scrapped, bringing unnecessary cost increase and efficiency loss to the production line. In addition, frequent adjustment and repair also consume a large amount of human and material resources, affecting the continuity and stability of production. Content of the Utility Model

[0004] The purpose of the utility model is to provide a novel buckle pre-assembly structure to solve the problems of pre-assembly failure and side panel falling off and being scrapped caused by buckle angle deviation during the pre-assembly of the current vehicle side panel and the lower floor as mentioned in the above background art.

The limit block is installed on the base of the buckle pre-assembly tooling and is used to determine the in-place position of the buckle pre-assembly. The fixed positioning block is located at the upper end of the limit block and is fixedly connected to the base through a connecting block. The movable positioning block is connected to the end of the piston rod of the double-rod cylinder and can move along the direction of the fixed positioning block to press the buckle onto the fixed positioning block. And the double-rod cylinder is installed on the base, and the piston rod of the double-rod cylinder can drive the movable positioning block to move along the direction of the fixed positioning block.

[0006] Preferably, a limiting surface is provided inside the limit block, and the limiting surface inside the limit block matches the pre-assembly position of the buckle and is provided with anti-slip lines.

[0007] Preferably, the machined surface of the fixed positioning block is vertically distributed with the base, and a positioning groove is provided on the machined surface of the fixed positioning block.

[0009] Preferably, the cylinder block of the double-rod cylinder is fixedly connected to the base through a bracket, and the position of the double-rod cylinder is diagonally distributed relative to the limiting block.

[0010] Preferably, the movable positioning block is provided with a pressing surface matching the shape of the buckle, and the pressing surface on the movable positioning block is provided with anti-slip protrusions.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The novel buckle pre-assembly structure significantly improves the consistency and reliability of the pre-assembly of the automobile side wall and the lower floor, improves the production efficiency and reduces the maintenance cost.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-4, the present utility model provides a technical solution: a new type of buckle pre-assembly structure, including a base 1, a limit block 2, a fixed positioning block 3, a movable positioning block 4, and a double-rod cylinder 5. The limit block 2 is installed on the base 1 of the buckle pre-assembly tooling, used to determine the in-place position of the buckle pre-assembly. The fixed positioning block 3 is located above the limit block 2 and is fixedly connected to the base 1 through a connecting block. The movable positioning block 4 is connected to the end of the piston rod of the double-rod cylinder 5 and can move along the direction of the fixed positioning block 3 to press the buckle onto the fixed positioning block 3. And the double-rod cylinder 5 is installed on the base 1, and the piston rod of the double-rod cylinder 5 can drive the movable positioning block 4 to move along the direction of the fixed positioning block 3. The base 1 of this structure serves as the basic support platform for the entire new type of buckle pre-assembly structure. It bears all other components and ensures that they can work accurately and stably together during the pre-assembly process. The limit block 2 first ensures that the buckle is accurately positioned to the in-place position of the pre-assembly. The fixed positioning block 3 provides precise angular positioning for the buckle through its machined surface. And the movable positioning block 4, under the drive of the double-rod cylinder 5, presses the buckle onto the fixed positioning block 3, achieving efficient correction of the buckle angle, thus ensuring the consistency and reliability of the buckle pre-assembly. This structure effectively avoids the problem of pre-assembly failure caused by the angular deviation of the buckle in the traditional technology, reduces the risk of side panel shedding and scrapping, and further improves the production efficiency and reduces the maintenance cost. At the same time, it simplifies the operation process and is convenient for maintenance, and is applicable to the buckle pre-assembly process in fields such as automobile manufacturing. The inner side of the limit block 2 is provided with a limiting surface, and the limiting surface on the inner side of the limit block 2 matches the pre-assembly position of the buckle and is provided with anti-slip lines. The limit block 2 of this structure can ensure that the buckle can be accurately positioned to the in-place position of the pre-assembly and prevent the buckle from sliding during the pre-assembly process through the anti-slip lines, so as to ensure the consistency of the clamping in-place point each time, that is, the limiting surface of the limit block 2 contacts the buckle to ensure that the buckle stays accurately at the predetermined position. The anti-slip lines enhance the friction between the limit block 2 and the buckle, effectively preventing the buckle from shifting in position due to external forces during the pre-assembly process, and further ensuring the consistency and reliability of the pre-assembly. The machined surface of the fixed positioning block 3 is vertically distributed with the base 1, and a positioning groove is provided on the machined surface of the fixed positioning block 3. The fixed positioning block 3 of this structure can ensure that the buckle can be accurately positioned to the preset angle and matches the shape of the buckle after pre-bending through the positioning groove, so as to ensure that the angle of the buckle after pre-bending is consistent with the machined surface of the fixed positioning block 3, achieving precise angle correction and further ensuring the consistency and reliability of the pre-assembly. The movable positioning block 4 is connected to the piston rod of the double-rod cylinder 5 through a pin shaft, and a guiding groove is provided at the bottom of the movable positioning block 4. The movable positioning block 4 of this structure can move smoothly along the direction of the fixed positioning block 3 and accurately move along the direction of the fixed positioning block 3 through the guiding groove, so as to ensure that the position of the buckle is accurate when it is pressed onto the fixed positioning block 3, achieving efficient correction of the buckle angle. The cylinder block of the double-rod cylinder 5 is fixedly connected to the base 1 through a bracket,Moreover, the positions of the double-rod cylinder 5 are diagonally distributed relative to the limit block 2. The double-rod cylinder 5 with this structure can stably provide driving force, enabling the movable positioning block 4 to move along the direction of the fixed positioning block 3, thereby more effectively pressing the buckle onto the fixed positioning block 3. The movable positioning block 4 is provided with a pressing surface matching the shape of the buckle, and the pressing surface on the movable positioning block 4 is provided with anti-slip protrusions. When the double-rod cylinder 5 works, the movable positioning block 4 moves along the direction of the fixed positioning block 3, its pressing surface is in close contact with the buckle, and the anti-slip protrusions ensure that the buckle will not slide during the pressing process, thus ensuring that the buckle can be accurately pre-assembled at the angle set by the fixed positioning block 3, further improving the consistency and reliability of the pre-assembly.

[0019] Working principle: When using this new buckle pre-assembly structure, first place the buckle on the limiting surface of the limit block 2. The limiting surface of the limit block 2 matches the pre-assembly position of the buckle and is provided with anti-slip lines to ensure that the buckle can be accurately positioned to the pre-assembled position. Then, through the positioning groove on the machined surface of the fixed positioning block 3, the buckle is accurately positioned to the preset angle. Subsequently, start the double-rod cylinder 5. The double-rod cylinder 5 drives the movable positioning block 4 to move along the direction of the fixed positioning block 3. The movable positioning block 4 moves smoothly through the guiding groove at the bottom and presses the buckle onto the fixed positioning block 3. Finally, the pressing surface on the movable positioning block 4 is in close contact with the buckle, and the anti-slip protrusions on the pressing surface ensure that the buckle will not slide during the pressing process, realizing the accurate correction of the buckle angle and completing the pre-assembly process, thus completing a series of operations.
