Description

Technical Field

[0001] This utility model relates to the field of processing technology for cooling modules of engineering machinery, and specifically to an assembly tooling for cooling modules of engineering machinery. Background Technology

[0002] When construction machinery is in operation, cooling modules are needed for real-time cooling to prevent the equipment from overheating. For example... Figures 1-3 The diagram illustrates a cooling module for engineering machinery, comprising a rectangular frame. The rectangular frame is assembled from four end-to-end components: a bottom frame A, a right frame B, a top frame C, and a left frame D. Inside the rectangular frame, from left to right, are sequentially fitted a water cooler E, an oil cooler F, and an air cooler G. The upper ends of the water cooler E, oil cooler F, and air cooler G are fixedly fitted into a downward-opening cavity inside the top frame C, and the lower ends are fixedly fitted into an upward-opening cavity inside the bottom frame A. Two vertical stiffeners L are fixedly spaced on the rear sides of the bottom frame A and the top frame C. Two horizontal stiffeners J for mounting fans are fixedly spaced on the front sides of the left frame D and the right frame B. A fan shroud K is fixedly mounted on the front side of the rectangular frame. The module also includes a fuel filler located horizontally at the lower right corner of the rear side of the rectangular frame. The cooler M is a fuel cooler with one end vertically fixed to the rear side of the left side frame D and the other end vertically fixed to the rear side of a vertical stiffener L near the left side frame D. The water inlet pipe E-1 at the upper end of the water cooler E, the oil inlet pipe F-1 at the upper end of the oil cooler F, and the air inlet pipe G-1 at the upper end of the air cooler G pass through the notch on the front side wall of the top frame C and the notch on the top edge of the fan shroud K to the front outside of the rectangular frame. The water outlet pipe E-2 and the drain pipe E-3 at the lower end of the water cooler E, the oil outlet pipe F-2 at the lower end of the oil cooler F, and the air outlet pipe G-2 at the lower end of the air cooler G pass through the notch on the front side wall of the bottom frame A and the notch on the bottom edge of the fan shroud K to the front outside of the rectangular frame. Bottom support plates H along the front-rear direction are fixed at the left and right ends of the lower end face of the bottom frame A. The aforementioned engineering machinery cooling modules are currently assembled using a manual splicing method. This manual splicing method has the following problems: (1) The rectangular frame assembly is greatly affected by human factors, making it difficult to assemble correctly in one go. If the rectangular frame is found to be inaccurate when assembling other components, the screws at the corners of the rectangular frame need to be loosened for secondary or even multiple adjustments, severely restricting the overall assembly efficiency of the engineering machinery cooling modules and making it difficult to meet the demand for large-volume delivery; (2) It requires a high level of technical skill from operators. If the operators lack experience, the assembly efficiency of the engineering machinery cooling modules will further decrease, leading to a large workload and high labor costs for the operators. This utility model proposes an assembly fixture for engineering machinery cooling modules to solve the above-mentioned technical problems. Summary of the Invention

[0003] The purpose of this utility model is to overcome the defects existing in the prior art and provide an assembly fixture for cooling modules of engineering machinery. In use, firstly, two bottom support plates are positioned and installed on positioning components three at the left and right ends of the base plate. Secondly, the bottom frame is positioned and installed on positioning component two in the middle of the base plate. Thirdly, the lower ends of the water cooler, oil cooler, and air cooler are embedded in the internal cavity of the bottom frame. Fourthly, the top frame is snapped onto the upper ends of the water cooler, oil cooler, and air cooler. Finally, the left and right frames are positioned and installed on positioning components one on a corresponding set of vertical supports, and the two sets of vertical supports are pushed towards the middle of the base plate so that the left and right frames are aligned and fixed with the bottom and top frames to form a rectangular frame structure. Compared with the traditional manual assembly method, this significantly improves the accuracy of the alignment of various components. A rectangular frame assembled in one step can meet the requirements. It requires low technical skills from operators, is easy to operate, helps to significantly reduce manual labor and fatigue, and significantly improves the finished product quality and assembly efficiency of the engineering machinery cooling module, helping to meet the needs of large-volume delivery.

On the vertical surfaces of the two sets of vertical supports on opposite sides, there are positioning components one for positioning the left or right side frame of the cooling module of the engineering machinery. The middle of the upper side of the base plate has positioning components two for positioning the bottom frame of the cooling module of the engineering machinery. At the left and right ends of the upper side of the base plate, there are positioning components three for positioning the corresponding bottom support plate of the cooling module of the engineering machinery.

[0005] This utility model discloses an assembly fixture for cooling modules of engineering machinery. In use, firstly, two bottom support plates are positioned and installed on positioning components three at the left and right ends of the base plate. Secondly, the bottom frame is positioned and installed on positioning component two in the middle of the base plate. Thirdly, the lower ends of the water cooler, oil cooler, and air cooler are embedded in the internal cavity of the bottom frame.

Finally, the left and right frames are positioned and installed on positioning components one on corresponding sets of vertical supports, and the two sets of vertical supports are pushed towards the middle of the base plate to align and fix the left and right frames with the bottom and top frames into a rectangular frame structure. Compared with traditional manual assembly methods, this significantly improves the accuracy of splicing and aligning of various components. A rectangular frame assembled in one step can meet the requirements. It requires low operator skill levels, is highly operable, and helps to significantly reduce manual labor and fatigue. It significantly improves the finished product quality and assembly efficiency of the engineering machinery cooling module, helping to meet the needs of large-volume delivery.

[0006] The preferred technical solution is that the positioning component includes a plurality of U-shaped blocks fixedly fixed along the longitudinal direction on the vertical side of a set of vertical supports facing the middle of the base plate. The openings of the plurality of U-shaped blocks face the other set of vertical supports, and the inner openings of the plurality of U-shaped blocks are correspondingly formed to form positioning grooves for positioning and embedding the left or right side frame of the engineering machinery cooling module. One side arm of the U-shaped block has a positioning hole that communicates with its inner opening.

[0007] The positioning component 2 includes several U-shaped blocks 2 fixed at intervals along the horizontal direction on the middle of the side of the base plate. The openings of the several U-shaped blocks 2 all face upward, and the inner openings of the several U-shaped blocks 2 are correspondingly formed to form positioning grooves 2 for positioning and embedding the bottom frame of the engineering machinery cooling module.

[0008] The third positioning component includes a base plate, which is laid flat and fixed to the left or right end of the upper side of the base plate.
