[0037] Furthermore, the accompanying drawings are not drawn to a 1:1 scale, and the relative dimensions of the components are shown in the drawings only as examples and not necessarily to actual scale.
[0038] like Figures 1-3 The accompanying drawing shows a structural diagram of a position gauge for a motor suspension bracket according to an embodiment of the present invention; for ease of description, the drawing only shows the structure related to the embodiment of the present invention.
[0039] This application provides a position measurement tool for a motor suspension bracket, including a base plate 1, a linear guide rail 2, a connector 6, a guide seat 7, a first detection pin 10, a second detection pin 11, a first positioning post 8, a second positioning post 9, a quick clamp 5, a first limiting member 3, a second limiting member 4, and a handle 13. The components work together to achieve efficient position measurement of the motor suspension bracket product 12.
[0040] In this embodiment, the base plate 1 is a rectangular plate, which serves as the support base for the entire fixture; its surface is precision machined to ensure that the flatness error is less than 0.05mm; furthermore, a pair of handles 13 are symmetrically fixedly installed on both sides of the base plate 1. The handles 13 are arranged parallel to the extension direction of the linear guide rail 2, and their outer surfaces are covered with an anti-slip rubber layer, which makes it easy for operators to hold and move the fixture.
[0041] In this embodiment, the linear guide rail 2 is fixed to the center of the upper surface of the base plate 1 by bolts, and its length direction is parallel to the long side of the base plate 1. A first limiting member 3 and a second limiting member 4 are respectively installed at both ends of the guide rail. Both are limiting block structures and are fastened to the ends of the guide rail by threads to limit the sliding range of the connecting member 6 and prevent it from falling off the guide rail.
[0042] In this embodiment, the connector 6 is a slider structure that slides with the linear guide rail 2 and can move freely along the length of the guide rail.
[0043] In this embodiment, a quick clamp 5 is provided on the right side wall of the connector 6. The handle of the quick clamp 5 faces outward. When the connector 6 slides to the target position, tightening the quick clamp 5 can lock the connector 6 and ensure the stability of the guide seat 7.
[0044] In this embodiment, the guide seat 7 is an "I"-shaped component, vertically fixed to the top of the connector 6 by bolts. The structure of the guide seat 7 includes a laterally extending support portion and a longitudinally extending guide portion. The support portion is connected to the connector 6, and the guide portion extends toward the motor suspension bracket product 12. The second detection pin 11 is vertically installed at the end of the guide portion by an interference fit, and its axial direction is consistent with the detection direction of the detection point B. The diameter tolerance of the second detection pin 11 matches the detection hole tolerance of the motor suspension bracket product 12, forming a clearance fit to detect the positional accuracy of the detection point B.
[0045] In this embodiment, a first positioning post 8 and a second positioning post 9 are respectively installed on both sides of the upper surface of the base plate 1 near the linear guide rail 2. The two positioning posts are diagonally distributed, and their height is designed according to the specifications of the motor suspension bracket product 12. The top has a tapered guide structure to facilitate the rapid positioning of the motor suspension bracket product 12. The first detection pin 10 is fixed on the base plate 1 and located directly below the detection point A at the bottom of the motor suspension bracket product 12. Its diameter tolerance also matches the detection hole to detect the position accuracy of the detection point A.
[0046] In practice, the testing process for this utility model is as follows:
[0047] The motor suspension bracket product 12 is placed on the base plate 1, and the initial positioning is completed by the tapered guide structure of the first positioning post 8 and the second positioning post 9 to ensure the positioning of the motor suspension bracket product 12.
[0048] Slide the connecting piece 6 along the linear guide rail 2 to drive the guide seat 7 and the second detection pin 11 to move toward the motor suspension bracket product 12; when the second detection pin 11 is aligned with the detection point B, tighten the quick clamp 5 to fix the position of the connecting piece 6.
[0049] Observe whether the second detection pin 11 can be smoothly inserted into the hole of detection point B, and at the same time check the fit between the first detection pin 10 and detection point A;
[0050] If both detection pins can be inserted without interference, the product's position is deemed to be qualified.
[0051] After the test is completed, release the quick clamp 5, reset the connector 6 to its initial position, and remove the motor suspension bracket product 12 to proceed to the next round of testing.
[0052] This utility model has a reasonable structure and is easy to operate. Through the synergistic effect of the linear guide rail 2 and the quick clamp 5, the guide seat 7 can be quickly positioned and locked, reducing the time for manual adjustment. The design of the "I"-shaped guide seat 7 enhances the stability of the second detection pin 11 and avoids deviation caused by force during the detection process. The diagonally distributed first positioning post 8 and second positioning post 9 ensure the stability of the motor suspension bracket product 12 and reduce the impact of vibration or operation error on the detection results. The symmetrical arrangement of the handle 13 and the rubber layer design take into account both portability and operational safety.
[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0054] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
