[0019] The embodiment of the present application effectively solves the problem of detecting the position accuracy of the axis lines of the two pulley grooves by providing a checking fixture for the mutual position of the wheel grooves of the same pulley system. Generally, indirect measurement is used, which is not accurate enough and has a large deviation. If the axis position deviation is large, the belt will deflect and twist during operation, which will accelerate the damage of the belt and shorten its service life. The deviation of the axis positions of the two pulleys seriously affects the service life of the belt. The bottom ends of the measuring body and the positioning body are both conical in design and can be placed inside the wheel groove. The measuring body passes through the wheel groove on the surface of the pulley body, and the gap between the two side surfaces of the wheel groove and the measuring body is respectively detected with a feeler gauge. The difference between the gaps on both sides is the deviation size of the axis positions of the two pulley grooves. By measuring with this checking fixture, the deviation of the axis positions of the two pulley bodies can be detected conveniently, accurately and quickly.

[0020] Example

[0021] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the problem of detecting the position accuracy of the axis of the two pulley grooves. Generally, the measurement is performed indirectly, which is not accurate enough and has a large deviation. If the axis position deviation is large, the belt will be deflected and twisted during operation, accelerating the damage of the belt and shortening its service life. The technical problem that the position deviation of the two pulley axes seriously affects the service life of the belt is solved. The overall idea is as follows:

[0022] In response to the problems existing in the prior art, the utility model provides a measuring tool for measuring the mutual position of the wheel grooves of the same pulley system, comprising two pulley bodies 17, the tops of the two pulley bodies 17 are both provided with the same measuring body 11, the side ends of the measuring body 11 are movably mounted with a connecting block 13, the side ends of the connecting block 13 are provided with a positioning body 12, the bottom ends of the measuring body 11 and the positioning body 12 are both conical in design and can be placed inside the wheel groove, the measuring body 11 passes through the wheel groove on the surface of the pulley body 17, and the gap between the two side surfaces of the wheel groove and the measuring body 11 is respectively detected with a feeler gauge, and the difference between the gaps on both sides is the wheel groove axis of the two pulleys The linear position deviation size can be measured by this inspection fixture, which can conveniently, accurately and quickly detect the axis position deviation of the two pulley bodies 17 and adjust it to ensure that the axis position deviation of the pulley body 17 is within a reasonable range. At least two fixing bolts 14 are installed for rotation inside the connecting block 13. Two second threaded openings 16 are provided at the side end of the measuring body 11, and a first threaded opening 15 is provided at the side end of the positioning body 12. The positioning body 12 is a trapezoidal cuboid with a bevel on one side. The bottom ends of the measuring body 11 and the positioning body 12 are both conical in design, and the positioning body 12 is fixed at an angle by a fixing bolt 14.

[0023] Working principle:

[0024] In the first step, the design angle between the measuring body 11 and the positioning body 12 is 38 degrees. The measuring body 11 is 300mm long and 15mm wide, and the positioning body 12 is 100mm long and 15mm wide. At the same time, the connecting block 13 is 50mm long and 5mm wide. At least two fixing bolts 14 are rotatably installed on the side end of the connecting block 13. A second threaded opening 16 and a first threaded opening 15 are respectively opened on the side ends of the measuring body 11 and the positioning body 12. By docking the side ends of the measuring body 11 and the positioning body 12 with the fixing bolts 14, and rotating the fixing bolts 14 so that the fixing bolts 14 are respectively rotated into the interior of the measuring body 11 and the positioning body 12, the measuring body 11 and the positioning body 12 are assembled and installed. At the same time, the two pulleys to be measured are The distance between the two bodies 17 is short, and the spacing must be within 300mm. The measuring body 11 and the positioning body 12 are simultaneously inserted into the wheel groove of the pulley body 17 as a positioning reference. Since the bottom ends of the measuring body 11 and the positioning body 12 are both tapered, they can be placed inside the wheel groove. The measuring body 11 passes through the wheel groove on the surface of the pulley body 17, and uses a feeler gauge to detect the gap between the two side surfaces of the wheel groove and the measuring body 11 respectively. The difference in the gap on both sides is the position deviation size of the axis of the two pulley grooves. By measuring with this inspection fixture, the position deviation of the axis of the two pulley bodies 17 can be detected conveniently, accurately and quickly, and adjusted to ensure that the position deviation of the axis of the pulley body 17 is within a reasonable range, thereby reducing wear and increasing the service life of components.
