Description

Technical Field

[0001] The invention relates to the technical field of automobile cooler components, in particular to a wire width adjustment device. Background Art

[0002] While the rapid development of the automotive industry has brought convenience to people's lives, it has also caused serious damage to the ecological environment. To limit the pollution caused by automobile exhaust, the country has issued a series of regulations setting emission limits. EGR cooler technology has emerged as a response to this and is widely used in automobiles, playing an indispensable role in dissipating exhaust gas heat and cooling. The compact engine space layout requires EGR coolers to have extremely strong heat exchange performance.

[0003] Common EGR cooler fins have a wavy structure. In order to improve the heat exchange performance, the existing technology optimizes the design of the fins into staggered zigzag shapes, forcing the gas to be continuously divided during the flow process, generating turbulence to improve thermal efficiency. During the production and transportation of the fins, the length of the fins needs to be determined according to the length of the mixing tube. The lengths of different models are inconsistent, so it is necessary to improve the adaptability of the fin production equipment to avoid the cost waste caused by replacing tooling parts. Therefore, a line width adjustment device is needed. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a wire width adjustment device for solving the problem of tooling adaptability in the prior art during the transportation of fins of different lengths.

[0005] To achieve the above-mentioned and other related purposes, the present invention provides the following technical solutions:

[0007] The width adjustment assembly includes two sets of trapezoidal screws mounted between two sets of brackets, the upper and lower surfaces of the trapezoidal screws are respectively provided with left and right threaded surfaces, two sets of conveying frames are provided between the two sets of material conveying belts and the trapezoidal screws, the material conveying belts are slidably connected to the conveying frames, the trapezoidal screws penetrate the conveying frames, and the two sets of conveying frames are respectively threadedly connected to the left and right threaded surfaces on the trapezoidal screws.

[0008] To implement the above technical solution, the fin material can be transported by setting two sets of material conveyor belts above the base and between the two sets of brackets. The width adjustment component can adjust the width between the two sets of material conveyor belts, so that the center position of the line body remains unchanged. The overall line body width can be widened or narrowed within a certain range, thereby realizing fast reading and changing of different models without having to replace any tooling parts.

[0009] By providing left and right threaded surfaces on the surface of the trapezoidal screw, when the trapezoidal screw is rotated, the two sets of conveying frames respectively threadedly connected to the left and right threaded surfaces on the trapezoidal screw can move relative to each other, so that the width of the line between the two sets of conveying frames can be widened or narrowed within a certain range to meet the needs of equipment use.

[0010] In one embodiment of the present invention, the driving assembly includes a driving shaft and an optical shaft respectively provided at both ends of the two sets of material conveyor belts, the driving shaft is a spline shaft, and the driving shaft is externally connected to a driving member.

[0011] To implement the above technical solution, by setting a drive shaft of the spline shaft, it is convenient for an external drive component to use the drive shaft to drive the material conveyor belt, and the optical shaft at the other end can reduce the friction during the movement of the material conveyor belt, thereby improving the practicality of the equipment.

[0012] In one embodiment of the present invention, a screw base is provided on the two sets of brackets, and the two sets of trapezoidal screws are both provided on the screw base. A screw base is provided between the two ends of the trapezoidal screw and the screw base. The screw base is detachably connected to the screw base, and the trapezoidal screw and the screw base are rotatably connected.

[0013] To implement the above technical solution, the setting of the screw base can provide stable support for the trapezoidal screw and ensure the reliability of the use of the trapezoidal screw. The screw base is detachably connected to the screw base, which can facilitate the movement of the screw base. A screw base is provided between the two ends of the trapezoidal screw and the screw base, which can facilitate the movement of the trapezoidal screw and maintain the position accuracy after movement.

A dust cover is provided on the screw base on the side equipped with the synchronous belt, and the dust cover covers the synchronous belt setting, and the handwheel extends out of the dust cover setting.

[0015] To implement the above technical solution, the setting of the synchronous belt can facilitate the driving synchronization of the two sets of trapezoidal screws and improve the driving convenience. The setting of the dust cover can reduce the impact of dust particles on the working stability of the synchronous belt. The setting of the handwheel can facilitate manual driving of the synchronous belt and improve the practicality of the equipment.

[0016] In one embodiment of the present invention, a limiting groove is provided between the left and right thread surfaces on the trapezoidal screw, and the radial dimension of the limiting groove is smaller than the radial dimension of the left and right thread surfaces of the trapezoidal screw.

[0017] By implementing the above technical solution, the setting of the limiting groove can avoid the overshoot of the two sets of trapezoidal screws during the displacement process, thereby ensuring the stability and reliability of the trapezoidal screws.

[0018] In one embodiment of the present invention, a limiting block is sleeved on the limiting groove, and the radial dimension of the limiting block is larger than the radial dimension of the left and right thread surface portions of the trapezoidal lead screw.

[0019] To implement the above technical solution, by setting a limit block, the overrun situation during the displacement of the two sets of trapezoidal screws can be avoided, and the radial size of the limit block is set to be larger than the radial size of the left and right threaded surface parts of the trapezoidal screw, which can block the displacement of the two sets of trapezoidal screws.

[0020] As described above, a wire width adjustment device of the present invention has the following beneficial effects: by providing left and right threaded surfaces on the surface of the trapezoidal screw, respectively, when the trapezoidal screw is rotated, the two groups of conveying racks respectively threadedly connected to the left and right threaded surfaces on the trapezoidal screw can move relative to each other, so that the wire width between the two groups of conveying racks can be widened or narrowed within a certain range to meet the needs of equipment use, and the two groups of material conveyor belts set above the base and between the two groups of brackets can realize the transportation of fin materials, and the setting of the width adjustment component can adjust the width between the two groups of material conveyor belts, so that the center position of the wire remains unchanged, and the overall wire width can be widened or narrowed within a certain range, thereby realizing fast reading and changing of different models without having to replace any tooling parts.
