[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0018] Example 1
[0019] like Figures 1 to 4As shown, a specific embodiment of a contour gauge for a sliding bracket described in the utility model comprises: a gauge base 1, a fixing buckle 2 for fixing a sliding bracket 3 is installed on the upper end surface of the gauge base 1, the sliding bracket 3 is placed on the gauge base 1 and clamped under the fixing buckle 2, a fixed limit block 4 and a movable limit block 5 are respectively installed on the front and rear sides of the upper end surface of the gauge base 1, the fixed limit block 4 and the movable limit block 5 are used to clamp the sliding bracket 3 front and back, a support 7 is also installed on the gauge base 1, a contour reference block 8 is installed on the support 7, a measuring hole is opened on the contour reference block 8, a pin gauge 9 is inserted in the measuring hole, and the pin gauge 9 is used to penetrate into the hole on the sliding bracket 3 to detect the deviation of the hole.
[0020] A tension adjustment head 6 is threadedly mounted on the movable limit block 5 , and the tension adjustment head 6 is used to adjust the clamping force of the sliding bracket 3 . By rotating the tension adjustment head 6 , the length of the movable limit block 5 can be adjusted, thereby adjusting the clamping force.
[0021] A handle 10 is provided on the left and right sides of the gauge base 1 , respectively, and the handle 10 is used to take, place and move the gauge.
[0022] The fixing buckle 2 is detachably mounted on the upper end surface of the gauge base 1 by means of fastening screws, so that the fixing buckle 2 can be easily replaced or repaired. There are three fixing buckles 2, which are evenly distributed around the sliding bracket 3. The support 7 and the contour reference block 8 are arranged in two groups, corresponding to the holes to be measured on the left and right sides of the sliding bracket 3, respectively.
[0023] Working principle of the utility model: the base 1 of the inspection tool provides a stable support for the sliding bracket 3, and the fixed buckle 2 installed thereon can firmly fix the sliding bracket 3 in a predetermined position, and the fixed limit block 4 and the movable limit block 5 work together to accurately position and clamp the sliding bracket 3 in the front and rear directions; the length of the movable limit block 5 is adjusted by adjusting the tension adjustment head 6, so as to adjust the clamping force; the contour reference block 8 is the core component of the inspection tool, and the measuring hole provided thereon corresponds to the hole on the sliding bracket 3. When the needle gauge 9 is inserted into the measuring hole and penetrates into the hole of the sliding bracket 3, the deviation of the hole can be intuitively judged by manual plugging and unplugging operations: if the needle gauge 9 can be inserted smoothly without obvious resistance, it means that the position and size of the hole meet the requirements; otherwise, it indicates that there is a deviation; secondly, a go / no-go gauge is used to measure whether the gap between the contour reference block 8 and the sliding bracket 3 meets the standard. In addition, the inspection tool is also provided with a handle 10, which is convenient for operators to take, place and move the inspection tool.

Various changes can be made within the knowledge of ordinary technicians in the field without departing from the purpose of the present invention, and modifications or deformations without creative labor are still within the scope of protection of the present invention.
