[0002] Excavators are currently widely used in civil engineering, water conservancy projects and other basic construction engineering machinery. Hydraulic excavators have complex movements and need to be started, braked, and switched frequently, which generates a lot of heat. Therefore, the effectiveness of the radiator will directly affect the use of the equipment. However, due to the common bumps in the working environment of the excavator, the installation plane and the installation holes of the radiator and the radiator's mounting frame may have large installation errors, making the radiator sensitive to vibrations, which in turn leads to failures and reduces the service life.

[0003] In order to improve the assembly accuracy between the radiator and the radiator mounting frame, generally, when the radiator mounting frame is received, manual inspection of the accuracy is usually adopted. Currently, calipers and tape measures are commonly used to measure the accuracy, which is time-consuming and labor-intensive, and has large errors. Summary of the invention

[0004] The purpose of the present application is to provide a check fixture for a radiator mounting frame, so as to improve the efficiency and accuracy of checking the machining precision of the radiator mounting frame.

[0006] A gauge positioning structure, used for aligning with the frame positioning structure;

[0007] The inspection tool body is formed with a first inspection plane for aligning a high-level inspection plane and a second inspection plane for aligning a low-level inspection plane. The first inspection plane and the second inspection plane are arranged in parallel and spaced apart.

[0033] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0034] The following describes a check fixture for a heat sink mounting frame according to the present application with reference to the accompanying drawings.

[0035] It should be noted that, in the present application, unless otherwise stated, “upper, lower, front, rear, inside, outside” generally refers to the directions shown in the accompanying drawings. When there is no reference to the accompanying drawings, “inside” and “outside” refer to the lateral inside and outside with the center line C as the reference.

[0036] The present application discloses a novel inspection tool for a radiator mounting frame, such as Figure 1 to Figure 4As shown, a gauge for a radiator mounting frame in a specific embodiment includes:

[0037] A gauge positioning structure, used for aligning with the frame positioning structure;

[0038] The inspection tool body is formed with a first inspection plane 100 for aligning a high-level inspection plane and a second inspection plane 200 for aligning a low-level inspection plane. The first inspection plane 100 and the second inspection plane 200 are arranged in parallel and spaced apart.

[0039] Specifically, see Figure 1 After the gauge for the radiator mounting frame is positioned relative to the frame positioning structure of the radiator mounting frame by the gauge positioning structure, the spatial position of the gauge for the radiator mounting frame on the horizontal plane is determined. After the first detection plane 100 is fitted with the high-position plane to be detected, the position of the gauge for the radiator mounting frame is determined. At this time, the operator visually confirms the fitting of the first detection plane 100 and the second detection plane 200 with the high-position plane to be detected and the low-position plane to be detected, respectively. When they are well fitted, it can be confirmed that the flatness of the high-position plane to be detected and the low-position plane to be detected meets the processing standard. In addition, since the first detection plane 100 and the second detection plane 200 are arranged in parallel and spaced apart, after the operator confirms that they are well fitted, it can be determined that the parallelism and distance between the high-position plane to be detected and the low-position plane to be detected also meet the processing requirements. Therefore, compared with the prior art, in which the operator measures the processing accuracy of the radiator mounting frame by tools such as calipers and tape measures, the detection efficiency of the gauge for the radiator mounting frame of the present application is high and the accuracy is good.

[0040] In this embodiment, if Figure 1 and Figure 2 As shown, the low-level plane to be detected may include a plurality of mounting holes, and the second detection plane 200 includes:

[0041] A plurality of positioning holes 210 are arranged in alignment with a plurality of mounting holes of the low-level plane to be detected.

[0042] Specifically, see Figure 1After the operator confirms that the first detection plane 100 and the second detection plane 200 are well fitted with the high-level plane to be detected and the low-level plane to be detected respectively, that is, the flatness of the high-level plane to be detected and the low-level plane to be detected as well as the parallelism and distance between the high-level plane to be detected and the low-level plane to be detected meet the installation requirements of the radiator, it can be detected whether the positioning holes 210 provided on the second detection plane 200 are aligned one by one with the mounting holes for radiator installation on the low-level plane to be detected, so as to confirm whether the mounting holes meet the manufacturing standards, wherein the operator can connect the mounting holes and the positioning holes 210 by holding the positioning pin to confirm that the mounting holes and the positioning holes 210 are aligned one by one.

[0043] In this embodiment, if Figure 1 and Figure 2 As shown, the gauge body may include U-shaped plates symmetrically arranged on both sides of the center line C of the first detection plane 100, and the U-shaped bottom surface of the U-shaped plate is the second detection plane 200;

[0044] The U-shaped plate includes a first straight plate, an end plate and a second straight plate connected in sequence, and the positioning hole 210 is provided on the end plate.

[0045] Specifically, see Figure 1 The design of forming the second detection plane 200 by the bottom surface of the U-shaped plate can not only save materials, but also ensure the structural strength of the second detection plane 200 through the frame structure of the U-shaped plate, so as to avoid the influence of the deformation of the inspection fixture body itself on the inspection result, thereby improving the inspection accuracy. The positioning hole 210 is set on the end plate, which can further save materials while ensuring the structural strength and facilitate positioning.

[0046] In this embodiment, if Figure 2 As shown, the inspection tool body may include a bottom plate with a four-frame structure, and the bottom surfaces of the four frames of the bottom plate are the first inspection plane 100 .

[0047] Specifically, see Figure 2 In this way, the four-frame structure is conducive to saving materials and ensuring the structural strength of the first detection plane 100. The middle of the left frame of the bottom plate is connected to the middle of the right frame by a reinforcing beam 110 to further improve the structural strength of the first detection plane 100, so as to avoid the influence of the deformation of the inspection fixture itself on the detection result and thus improve the detection accuracy.

[0048] Since the gauge used for the radiator mounting frame is large in size and is often made of metal, it is heavy and difficult to move manually and is easily deformed due to its own weight. Figure 3 As shown, the gauge body may further include a vertical plate 120 disposed around the circumference of the four frames. The vertical plate 120 is vertically disposed on the top surface of the frame, and the vertical plate 120 is a hollow structure.

[0049] Specifically, see Figure 3 and Figure 4 The gauge for the radiator mounting frame is preferably made of aluminum and is provided with vertical plates 120 arranged around the four sides of the frame. Such a configuration can save costs, reduce deadweight, and ensure its own strength, and the hook can be inserted into the hollow part of the hollow structure for hoisting, thereby facilitating the cooperation between the gauge for the radiator mounting frame and the radiator mounting frame.

[0050] In this embodiment, if Figures 1 to 3 As shown, the frame positioning structure may include a first frame edge located on a first side of the high-level plane to be detected, and the fixture positioning structure also includes a positioning block 400, which extends downward from the side of the fixture body and is used to abut against the first frame edge for positioning.

[0051] Specifically, see Figure 1 The end of the positioning block 400 extending downward forms a clamping positioning portion, and the front side of the clamping positioning portion can abut against the radiator mounting frame, thereby realizing the positioning of the inspection fixture for the radiator mounting frame relative to the first frame edge. Such an arrangement is convenient for positioning, simple in structure and easy to process.

[0052] The formation orientation of the snap-fit ​​positioning portion is not limited to the rear side of the heat sink mounting frame, and may also be other orientations.

[0053] On the basis of realizing the positioning of the gauge for the heat sink mounting frame relative to the first frame edge, in this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the frame positioning structure may further include a second frame edge located on the second side of the high-level plane to be detected, and the inspection fixture positioning structure may further include an auxiliary positioning block 500, which extends downward from the side of the inspection fixture body and is used to abut against the second frame edge for positioning.

[0054] Specifically, see Figure 1 The end of the auxiliary positioning block 500 extending downward forms an auxiliary clamping positioning portion, the inner side of which can abut against the radiator mounting frame, so as to perform secondary positioning relative to the second frame edge on the basis of realizing the positioning of the gauge for the radiator mounting frame relative to the first frame edge. Such a setting is convenient for positioning, simple in structure, easy to process and has a better positioning effect.

[0055] The formation orientation of the auxiliary clamping and positioning portion is not limited to the outer side of the heat sink mounting frame, and may also be other orientations.

[0056] When the distance between the high-level plane to be detected and the low-level plane to be detected does not meet the processing requirements, the error between the distance and the processing standard should be considered. Figure 1 , Figure 3 and Figure 4 As shown, the gauge body may also include:

[0057] The adjusting rod 600 is suspended from the first detection plane 100 and extends downward toward the second detection plane 200 and is used to detect the distance between the lower detection plane and the first detection plane 100 .

[0058] Specifically, see Figure 1 , by adjusting the height of the adjusting rod 600 until the bottom end of the adjusting rod 600 abuts against the low-position plane to be detected, the length of the adjusting rod 600 is the distance between the low-position plane to be detected and the first detection plane 100. After obtaining the distance, the operator can perform subsequent processing on the radiator mounting frame according to the error, so that the radiator mounting frame meets the radiator installation requirements.

[0059] In this embodiment, if Figure 1 As shown, there may be a plurality of adjusting rods 600 , and the top end of the adjusting rod 600 may be screwed to the side edge of the first detection plane 100 .

[0060] Specifically, see Figure 1 , the distance between the low-position plane to be detected and the first detection plane 100 can be detected by rotating a plurality of adjustment rods 600, so that the error between the distance and the processing standard can be detected more accurately, thereby facilitating the subsequent processing of the operator. Such a setting has a simple structure, accurate measurement, convenient operation and easy processing.

[0061] In this embodiment, the radiator mounting frame is disposed on an excavator.

[0062] Obviously, all the technical effects brought by the above-mentioned inspection fixture for the radiator mounting frame can also improve the processing efficiency of the radiator mounting frame of the excavator and reduce the cost.
