[0002] In the production and manufacturing process of heavy trucks, the bracket on the inner panel of the front door pillar is a key structure connecting the vehicle body and related components of the front door. Its installation accuracy directly affects the assembly quality of the front door, the smoothness of opening and closing, and the overall stability of the vehicle body.

[0003] Currently, patent document CN205129230U discloses a limiting device for a bracket on the inner panel of a heavy-duty truck front door pillar. It includes a base A for placing a connecting plate a on the inner panel of the front door pillar. An upper clamp is positioned above the base A. The upper clamp includes first and second limiting blocks arranged in parallel, sequentially arranged along a direction gradually approaching the rotating mechanism of the upper clamp. The second limiting block is positioned higher than the first limiting block. A strip-shaped groove is provided at the lower end of the second limiting block along the length of the bracket on the inner panel of the front door pillar. The width of the strip-shaped groove is equal to the width of the bracket on the inner panel of the front door pillar, and the depth of the strip-shaped groove is equal to the thickness of the bracket on the inner panel of the front door pillar. The shape of the strip-shaped groove matches the upper arc-shaped contour of the bracket on the inner panel of the front door pillar. The first and second limiting blocks of the upper clamp constitute a limiting device for the welding fixture of the bracket on the inner panel of the front door pillar, ensuring the stability of the welding.

[0004] In practical use, it was found that the spacing and placement height between the first and second limiting blocks are fixed. When facing brackets on the inner panel of the front door pillar of heavy trucks of different models and sizes, it is not convenient to adjust the position and height of the first and second limiting blocks as needed. Therefore, we proposed a limiting device for the bracket on the inner panel of the front door pillar of heavy trucks to solve the above problems. Utility Model Content

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a bracket limiting device on the inner panel of the front door pillar of a heavy truck, including a fixed base, a column installed on the top of the fixed base, an upper clamp slidably sleeved on the column, and a limiting block one and a limiting block two for limiting the upper bracket below the upper clamp, with the limiting block two located to the right of the limiting block one; a rectangular mounting hole is opened on the top of the upper clamp, and mounting seats are fixedly installed on the tops of the limiting blocks one and two, the mounting seats are installed in the rectangular mounting hole, and the mounting seats can slide horizontally within the rectangular mounting hole, a fixing screw is fixedly installed on the top of the mounting seat, the fixing screw passes through the rectangular mounting hole and is threaded with a fixing nut, and the bottom of the fixing nut contacts the top of the upper clamp.

[0007] A further feature of this invention is that multiple handles are fixedly installed on the outer side of the fixing nut, and the multiple handles are arranged in a ring with equal spacing.

[0008] By adopting the above technical solution, the handle allows operators to easily rotate the fixing nut without the need for additional tools, improving operational convenience and saving adjustment time.

[0009] A further feature of this invention is that a horizontal plate is fixedly installed on the top of the column, and a limiting guide mechanism is provided between the upper clamp and the horizontal plate.

[0010] By adopting the above technical solution, the limiting and guiding mechanism can limit and guide the sliding direction of the upper clamp, prevent the upper clamp from deviating during the up and down sliding process, ensure the stability and accuracy of the upper clamp's movement, and thus ensure the limiting accuracy of the limit block one and limit block two on the bracket on the inner plate of the front door pillar of the heavy truck.

[0011] A further feature of this invention is that the limiting and guiding mechanism includes a fixed plate and a guide rod. The fixed plate is fixedly installed on the column, and the guide rod is fixedly installed on the top of the fixed plate.
