[0003] Since the quality of the refrigerator door hinge 100 directly affects the installation effect of the refrigerator door, the deviation of the rotating shaft 101 or the hole position 102 on the refrigerator door hinge 100, the poor perpendicularity of the rotating shaft 101, or the poor flatness of the surface of the refrigerator door hinge 100 will all cause the refrigerator door to be offset or tilted after being installed on the refrigerator body, resulting in the refrigerator door being unable to close normally and affecting the sealing performance of the refrigerator. Therefore, it is necessary to detect the shape of the refrigerator door hinge 100 before assembly to screen out the refrigerator door hinges 100 with poor quality. However, using measuring tools such as vernier calipers to measure the refrigerator door hinge 100 has low efficiency and poor reliability. Summary of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides a detection tooling for a refrigerator door hinge, which solves the problems of low detection efficiency and poor reliability of the refrigerator door hinge in the prior art.

[0009] Further, a vertical limiting rod is provided on the base body, and a limiting hole matching with the limiting rod is provided on the detection block.

[0010] Further, a first spring is sleeved on the limiting rod. The opposite two ends in the telescopic direction of the first spring are respectively abutted against the base body and the detection block, and the first spring drives the detection block to move away from the base body.

[0011] Further, the driving assembly includes a guiding base. A movable slider is provided on the guiding base, and the moving direction of the slider is horizontal. A rotatable connecting rod is provided on the slider, and one end of the connecting rod far away from the slider is rotatably connected with the detection block.

DETAILED DESCRIPTION

[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figures 1 to 6 As shown, an embodiment of the utility model proposes a refrigerator door hinge inspection tool for inspecting the quality of the refrigerator door hinge 100 product to ensure that the surface flatness of the refrigerator door hinge 100 product, the positions of the rotating shaft 101 and the hole 102, and the verticality of the rotating shaft 101 meet the requirements, thereby preventing defects such as offset or tilting of the refrigerator door after assembly.

[0025] Please refer to Figure 1 , Figure 2 and Figure 3, the refrigerator door hinge detection tooling includes a base body 1, the base body 1 has a profiling groove 11 for accommodating the refrigerator door hinge 100 to be detected, the profiling groove 11 has parallel first and second support surfaces 12 and 13, and the height where the first support surface 12 is located is greater than the height where the second support surface 13 is located. The first support surface 12 has a positioning hole 14 for accommodating one end of the rotating shaft 101 on the refrigerator door hinge 100. The base body 1 is also provided with a detection block 2 that can be lifted and lowered in the vertical direction and a driving component 3 for driving the detection block 2 to lift and lower in the vertical direction. One side of the detection block 2 close to the base body 1 has a detection hole 21, and the center of the detection hole 21 and the center of the positioning hole 14 are located on the same vertical line. The second support surface 13 is also provided with a plurality of protruding positioning posts 15, and the positioning posts 15 are spaced apart on the second support surface 13.

[0026] Specifically, the operation steps for detecting the refrigerator door hinge 100 using the refrigerator door hinge detection tooling provided in this embodiment are as follows: Place the refrigerator door hinge 100 into the profiling groove 11 so that the first support surface 12 and the second support surface 13 are respectively in contact with the refrigerator door hinge 100. If both the first support surface 12 and the second support surface 13 can fit well with the refrigerator door hinge 100, it indicates that the flatness of the surface of the refrigerator door hinge 100 is good; after the refrigerator door hinge 100 is placed into the profiling groove 11, one end of the rotating shaft 101 on the refrigerator door hinge 100 extends into the positioning hole 14, and at the same time, the positioning posts 15 are inserted into the hole positions 102 on the refrigerator door hinge 100 to respectively detect the position of the rotating shaft 101 and the position of the hole positions 102 on the refrigerator door hinge 100. If one end of the rotating shaft 101 can normally cooperate with the positioning hole 14 and the positioning posts 15 can all be inserted into the corresponding hole positions 102, it indicates that the positions of the rotating shaft 101 and the hole positions 102 on the refrigerator door hinge 100 are qualified; after the refrigerator door hinge 100 is placed into the profiling groove 11, the driving component 3 drives the detection block 2 to descend so that one end of the rotating shaft 101 extends into the detection hole 21. If the rotating shaft 101 can be normally inserted into the detection hole 21, it indicates that the perpendicularity of the rotating shaft 101 is good. After the detection is completed, the detection block 2 is reset under the drive of the driving component 3, and the refrigerator door hinge 100 is taken out from the profiling groove 11 to complete the detection. The refrigerator door hinge detection tooling provided in this embodiment can comprehensively detect the quality of the refrigerator door hinge 100, improve the detection efficiency of the refrigerator door hinge 100 products, and the detection results are reliable while the detection operation is simple and convenient.

[0027] Such as Figure 2 And Figure 3As shown, the profiling groove 11 further includes a connecting surface 16 connecting the first support surface 12 and the second support surface 13, and an avoidance groove 17 is provided on the connecting surface 16. The connecting surface 16 is used to support the refrigerator door hinge 100, so that the position of the refrigerator door hinge 100 in the profiling groove 11 remains stable during the detection process, preventing the refrigerator door hinge 100 from moving unexpectedly. And the avoidance groove 17 is used to avoid the protruding part on the refrigerator door hinge 100, avoiding deformation of the refrigerator door hinge 100 when the refrigerator door hinge 100 is pressed against the first support surface 12 or the second support surface 13.

[0028] Specifically, a receiving groove 4 is further provided on the base body 1, and the receiving groove 4 is arranged around the profiling groove 11. By providing the receiving groove 4 around the profiling groove 11 on the base body 1, the receiving groove 4 is used to accommodate the edge part of the refrigerator door hinge 100, so as to improve the tightness of the cooperation between the refrigerator door hinge 100 and the base body 1, keep the refrigerator door hinge 100 in the profiling groove 11 and avoid damage to the refrigerator door hinge 100 caused by extrusion during the detection process. And one side of the receiving groove 4 away from the profiling groove 11 has a fillet 41, and the fillet 41 is used to guide the refrigerator door hinge 100 to fall into the receiving groove 4 and the profiling groove 11, preventing the refrigerator door hinge 100 from being damaged by friction with the base body 1.

[0029] Please refer to Figure 3 and Figure 4 , a vertical limiting rod 5 is further provided on the base body 1, and a limiting hole matching with the limiting rod 5 is provided on the detection block 2. The limiting rod 5 is used to limit the moving direction of the detection block 2, so that the detection block 2 can only move reciprocally in the vertical direction, preventing the position of the detection hole 21 from shifting due to the detection block 2 moving deviating from the preset direction and affecting the detection accuracy.

[0030] Specifically, a first spring 51 is sleeved on the limiting rod 5, and the opposite ends of the first spring 51 in the telescopic direction are respectively abutted against the base body 1 and the detection block 2, and the first spring 51 drives the detection block 2 to move away from the base body 1. When the detection block 2 moves towards the base body 1, the first spring 51 is compressed. After the detection is completed, the elastic force provided by the first spring 51 is used to push the detection block 2 to move away from the base body 1 and reset. At this time, the first spring 51 returns to its original length, ensuring that the detection block 2 resets and moves away from the refrigerator door hinge 100 after the detection is completed, so as to facilitate taking out the detected refrigerator door hinge 100 from the base body 1.

[0031] Such as Figure 3 , Figure 5 and Figure 6As shown, the driving assembly 3 includes a guide seat 31, a movable slider 32 is provided on the guide seat 31, and the moving direction of the slider 32 is horizontal, and a rotatable connecting rod 33 is provided on the slider 32, and one end of the connecting rod 33 away from the slider 32 is rotatably connected to the detection block 2. The movement of the slider 32 on the guide seat 31 drives the connecting rod 33 to rotate, and when the connecting rod 33 rotates, it pulls the detection block 2 to move, and the detection block 2 can be driven to move in the vertical direction, and the moving direction of the slider 32 can be controlled by toggling the slider 32 to control the moving direction of the slider 32, so as to control the detection block 2 to descend in the vertical direction to detect the refrigerator door hinge 100 and reset after the detection is completed.

[0032] In detail, the guide seat 31 is provided with a guide rod 34, the axial direction of the guide rod 34 is consistent with the moving direction of the slider 32, and the slider 32 is provided with a guide hole matched with the guide rod 34. The guide rod 34 is used to limit the moving direction of the slider 32 on the guide seat 31, ensuring that the slider 32 moves along the preset direction and drives the connecting rod 33 to rotate, so as to prevent the slider 32 from deviating from the preset direction and causing the driving assembly 3 to get stuck and fail to operate normally.

[0033] Please refer to Figure 5 and Figure 6 The guide rod 34 is sleeved with a second spring 35, and the opposite ends of the second spring 35 in the telescopic direction are respectively in contact with the guide seat 31 and the slider 32. The second spring 35 is used to drive the slider 32 to reset. When the slider 32 is moved to make the detection block 2 descend under the pull of the connecting rod 33, the second spring 35 is compressed. At this time, the detection block 2 is close to the refrigerator door hinge 100 to be detected and the rotating shaft 101 on the refrigerator door hinge 100 is inserted into the detection hole 21. After the detection is completed, the slider 32 is released. At this time, the second spring 35 restores its original length and pushes the slider 32 to reset by the elastic force provided by the second spring 35. During the reset of the slider 32, the connecting rod 33 rotates and pushes the detection block 2 to rise so that the detection block 2 is reset synchronously, so that the refrigerator door hinge 100 that has been detected can be taken out and a new refrigerator door hinge 100 to be detected can be put in, so that the refrigerator door hinge detection tooling can continuously perform detection operations, further improving the detection efficiency.

[0034] Specifically, a pull rod 36 is further provided on the slider 32. The length direction of the pull rod 36 is consistent with the moving direction of the slider 32, and a slotted opening for the pull rod 36 to pass through is provided on the guide seat 31. By pushing or pulling the connecting rod 33, the slider 32 can be conveniently moved. When the pull rod 36 is pulled, the slider 32 drives the detection block 2 to descend vertically and approach the refrigerator door hinge 100 to be detected. After the detection is completed, pushing the pull rod 36 can reset the slider 32, or releasing the pull rod 36 enables the second spring 35 to push the slider 32 to reset and drive the pull rod 36 to reset, facilitating the operation of the refrigerator door hinge detection tooling.
