[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] like Figures 1 to 4As shown, the utility model discloses a detection tool for the installation hole of the cutting platform bridge, including a frame 1, the frame 1 is rectangular as a whole, the frame 1 is an aluminum alloy frame, the overall weight of the frame 1 is reduced, it is convenient to carry, and the labor intensity is reduced. A detachable adjustment component is installed at the lower end of the frame 1, and a plurality of detection holes are provided on the frame 1. The number and position of the detection holes correspond to the number and position of the installation holes of the cutting platform bridge 8, respectively. A detection pin is inserted in the detection hole, and the detection pin is used to detect the installation hole of the cutting platform bridge 8. When in use, according to the different sizes of the feeding inlet of the cutting platform bridge 8, the height of the adjustment component at the bottom is adjusted, the detection tool is placed parallel to the feeding inlet of the cutting platform bridge 8, and the detection pin is inserted into the installation hole of the cutting platform bridge 8 for positioning detection, so that the relative positions of the plurality of installation holes of the cutting platform bridge 8 can be quickly detected to be qualified. The detection is convenient and quick, and the installation holes with excessive position can be quickly identified, so as to achieve accurate repair of the installation holes, reduce the number of overall repairs of the installation holes, and improve production efficiency.

[0022] In this embodiment, the adjustment assembly includes an adjustment pad 4 and a positioning block 5. The adjustment pad 4 and the positioning block 5 are detachably mounted on the frame 1 through fasteners, and the adjustment pad 4 is located between the frame 1 and the positioning block 5. Specifically, the fastener is a screw or a bolt, and two fasteners are provided. The positioning block 5 is provided with two corresponding receiving holes, and the end of the fastener is located in the receiving hole. The fastener passes through the receiving hole to install the adjustment point 4 and the positioning block 5 at the lower end of the frame 1, which is not only convenient for disassembly and assembly, but also ensures the flatness of the lower end surface of the positioning block 5, avoids the frame 1 from tilting, and ensures that the detection pin can accurately detect the position of the installation hole. By increasing or decreasing the number of adjustment points 4, the overall height of the frame 1 can be adjusted, thereby meeting the detection requirements of different models of header bridges 8, improving versatility, and reducing the cost of use.

[0023] Furthermore, two groups of adjustment components can increase the stability of the frame 1, reduce shaking, ensure the accuracy of detection, and can adjust the number of pads 4 in each group to one, two or more according to the size of the feeding port of the cutting platform bridge 8, thereby meeting the detection requirements of different models and facilitating operation.
