[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0017] It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a front suspension lower bracket comprehensive inspection tool of this embodiment includes a base 1 and a detection block 2, a first positioning column 3 and a plurality of first detection holes 4 are arranged above the base 1, the first positioning column 3 cooperates with one or more connection holes in the front suspension lower bracket 9 body, the first detection hole 4 corresponds to the plurality of connection holes in the front suspension lower bracket body, a detection rod 5 is inserted into the first detection hole 4, a second positioning column 6 is arranged at one end of the base 1, the second positioning column 6 cooperates with the axial hole of the front suspension lower bracket 9, and the front suspension lower bracket 9 is placed above the base 1 Afterwards, the first positioning column 3 cooperates with the connecting hole in the body of the front suspension lower bracket 9, and the second positioning column 6 cooperates with the axial hole of the front suspension lower bracket 9 to realize the positioning of the front suspension lower bracket 9; a pair of detection columns 7 are provided at the other end of the base 1, and a guide rod 8 is provided above the detection column 7. The diameter of the guide rod 8 is smaller than the diameter of the detection column 7, and the guide rod 8 passes through the detection block 2 and is slidably connected to the detection block 2. A second detection hole 21 is provided in the middle of the detection block 2, and the second detection hole 21 corresponds to the stepped shaft 91 of the front suspension lower bracket 9.

[0020] During inspection, the front suspension lower bracket 9 is placed above the base 1, the first positioning column 3 is inserted into the connecting hole of the body of the front suspension lower bracket 9, and the second positioning column 6 is inserted into the axial hole of the front suspension lower bracket 9. The front suspension lower bracket is positioned by the first positioning column 3 and the second positioning column 6, and the remaining connecting holes in the body are made to correspond to the first detection hole 4. The position of the connecting hole is detected by inserting the detection rod 5 through the connecting hole of the body into the first detection hole 4; the detection block 2 is inserted into the guide rod 8, and the contact between the detection block 2 and the detection column 7 and the step surface of the step shaft 91 is detected to detect the position or height difference between the step surface of the step shaft 91 and the end face of the axial hole and the end face of the connecting hole.

[0021] During detection, both ends of the detection block 2 are in contact with the upper end surface of the detection column 7, and the middle part of the detection block 2 is in contact with the step surface of the step shaft 91 of the front suspension lower bracket 9, that is, during detection, the small diameter axis of the step shaft 91 of the front suspension lower bracket 9 passes through the second detection hole 21, the bottom of the detection block 2 is in contact with the upper end surface of the detection column 7, and the middle part of the detection block 2 is in contact with the end surface of the large diameter axis of the step shaft 91 of the front suspension lower bracket 9; by taking the upper end surface of the detection column 7 as a reference, the height difference between the step surface of the step shaft 91 and the upper end surface of the detection column 7 is detected, so as to judge whether the positional accuracy between the step surface of the step shaft 91 of the front suspension lower bracket 9 and the end surface of the shaft hole and the end surface of the connecting hole meets the requirements.

[0022] After the front suspension lower bracket is placed above the base 1, the second detection hole 21 is coaxial with the stepped shaft 91 of the front suspension lower bracket. During inspection, it is convenient for the small diameter shaft of the front suspension lower bracket 9 to pass through the second detection hole 21, and the second detection hole 21 is used to detect whether the position of the axis hole of the front suspension lower bracket 9 and the stepped shaft 91 meets the requirements.

[0023] The depth of the second detection hole 21 is equal to the length of the small diameter shaft of the stepped shaft 91 of the front suspension lower bracket. During detection, the bottom surface of the detection block 2 contacts the stepped surface of the stepped shaft 91. The depth of the second detection hole 21 can be used to detect whether the length of the small diameter shaft of the stepped shaft 91 meets the processing requirements.

[0024] A cushion block 61 is provided at the bottom of the second positioning column 6. Since the end face of the axial hole of the front suspension lower bracket 9 and the end face of the main body of the front suspension lower bracket 9 are not at the same height or in the same plane, the end face of the axial hole can be supported by the cushion block 61, and the position of the end face of the axial hole relative to the end face of the connecting hole and the step surface of the stepped shaft 91 can be detected through the contact between the end face of the axial hole and the cushion block 61.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
