[0002] A vehicle centerline calibrator is a precision tool specifically designed to adjust and calibrate a vehicle's centerline. It can accurately detect whether a vehicle's centerline is offset while driving. In practice, vehicle centerline calibration tools typically require the following technologies:

[0003] 1. The measuring reference component is marked with scale on the reference rod so that the measurement data can be read intuitively;

[0004] 2. Adjust the mechanism and adjust the position to correct the center line of the vehicle;

[0005] 3. Install the fixing parts to firmly install the calibrator on the vehicle;

[0006] Install the calibrator's fixture at a suitable location on the vehicle, ensuring it is securely connected to the vehicle. Adjust the measuring pointer or probe to point to a specific measuring point on the vehicle, such as the wheel hub edge or axle center. The offset direction and magnitude of the vehicle's centerline can be determined based on the scale on the display.

[0007] In order to ensure stable use or accurate detection, the calibration tools are mostly fixedly connected between components. However, the hard connection method makes the tool larger, inconvenient to carry and transport, and limits the place of use. Utility Model Content

[0024] The embodiment of the present application provides a portable tracked vehicle centerline correction tool, which effectively solves the problem that the correction tool has a fixed connection structure between parts for stable use or accurate detection. However, the hard connection method makes the tool larger in size, inconvenient to carry and transport, and limits the use site. By rotating the two, the pre-tightening bolts drive the sleeve to rotate at the side end of the second mounting rod, and by moving the first mounting rod, the two ends of the first mounting rod are respectively disconnected from the inner sides of the two second mounting rods. By inserting the ring into the interior of the first slider and rotating the bolts at the side end of the ring, the ring is connected to the first mounting rod, and at the same time, one end of the support rod is connected to the second mounting rod, and the support rod is used to connect and assemble the first mounting rod and the second mounting rod. By designing the first mounting rod, the second mounting rod, and the support rod separately and then using them in combination, it is convenient to carry and replace.

[0025] Example

[0026] like Figure 1 - Figure 5 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the calibration tool has a fixed connection structure between the components in order to ensure stable use or accurate detection. However, the hard connection method makes the tool larger, inconvenient to carry and transport, and limits the use site. The overall idea is as follows:

[0027] In response to the problems existing in the prior art, the utility model provides a portable tracked vehicle centerline correction tool, comprising a first mounting rod 11 and a second mounting rod 12. The side end of the first mounting rod 11 is rotatably mounted with a threaded sleeve 14, the surface of the first mounting rod 11 is slidably mounted with a first slider 13, and both side ends of the second mounting rod 12 are rotatably mounted with pre-tightening bolts 16, the side end of each pre-tightening bolt 16 is slidably mounted with a sleeve 27, and the side end of each telescopic sleeve 27 is fixedly mounted with a buffer pad. 28. By rotating the pre-tightening bolt 16, the sleeve 27 is driven to rotate, and the sleeve 27 is rotated at the side end of the second mounting rod 12. At the same time, the pre-tightening bolt 16 moves toward the side end of the second mounting rod 12. At the same time, the spring 26 generates a pulling force on the engaging block 25, allowing the engaging block 25 to slide toward the inside of the sleeve 27. The side end of the pre-tightening bolt 16 drives the docking rod 24 to dock with the socket at the side end of the second mounting rod 12. The outer side of the first slider 13 is rotatably installed with a ring 18, and the outer surface of the ring 18 is fixedly installed with a support rod 17.

[0028] A balancing elbow 22 is slidably installed on the surface of the ring 18, and a reference line 23 is provided on the top of the balancing elbow 22. A hexagonal bolt 21 is rotatably installed on the bottom end of the balancing elbow 22. At least two scale lines 19 are provided on the surface of the support rod 17, and the multiple scale lines 19 are divided into two groups. A second slider 15 is slidably installed on the surface of the second mounting rod 12, and a fastening bolt is rotatably installed on the surface of the second slider 15. By moving the first mounting rod 11, the two ends of the first mounting rod 11 are respectively disconnected from the inner sides of the two second mounting rods 12, and the first mounting rod 11 is placed between the driving gear discs. By rotating the threaded sleeve 14, the interior of the threaded sleeve 14 is a threaded design, so that the overall length of the first mounting rod 11 is increased, and the two ends of the first mounting rod 11 are squeezed and fixed between the driving gear disc, and the side end of each pre-tightening bolt 16 is fixedly installed with a fitting block 25, and the side end of each fitting block 25 is fixedly installed with a spring 26. The inner side wall of each pre-tightening bolt 16 is fixedly installed with two docking rods 24.

[0029] Working principle:

[0030] In the first step, by rotating the two pre-tightening bolts 16, the pre-tightening bolts 16 drive the sleeve 27 to rotate on the side end of the second mounting rod 12. The reverse rotation of the sleeve 27 allows the side end of the sleeve 27 to reduce the extrusion of the two ends of the first mounting rod 11. By moving the first mounting rod 11, the two ends of the first mounting rod 11 are disconnected from the inner sides of the two second mounting rods 12 respectively, and the first mounting rod 11 is placed between the driving gear discs. By rotating the threaded sleeve 14, the interior of the threaded sleeve 14 is a threaded design, so that the overall length of the first mounting rod 11 is increased, and the two ends of the first mounting rod 11 are squeezed between the driving gear discs. Press and fix, and at the same time, push the first slider 13 to move the first slider 13 along the surface of the first mounting rod 11, and fix the position of the first slider 13 by tightening the bolts on the surface of the first slider 13, and clamp the second mounting rod 12 on the inducer. By rotating the pre-tightening bolt 16, the inside of the pre-tightening bolt 16 drives the sleeve 27 to rotate, and the sleeve 27 rotates at both ends of the second mounting rod 12, squeezing the side end of the inducer, and installing the second mounting rod 12. Put the correction line into the line groove of the active wheel and inducer correction tool. At this time, the center line of the action system can be corrected according to this correction line.

[0031] In the second step, after the correction tools of the driving wheel and the idler are installed respectively, adjust the position of the driving wheel and the idler, use brakes or other supports to fix the driving wheel and the idler so that the center correction line is flush with the center of the six torsion shaft mounting holes, and insert the ring 18 into the inside of the first slider 13, and connect the ring 18 to the first mounting rod 11 by rotating the bolts at the side end of the ring 18. At the same time, one end of the support rod 17 is connected to the second mounting rod 12. The support rod 17 plays a role in connecting and assembling the first mounting rod 11 and the second mounting rod 12. The support rod 17 is flush with the inner bearing shoulder, and the balancing elbow 22 is moved up and down to align the groove of the balancing elbow 22 with the pull line, and the corresponding torsion shaft is installed. The center line correction rod is placed parallel to the balancing elbow 22, and the fastening bolts are tightened. The balancing elbow 22 is moved horizontally to align the groove of the balancing elbow 22 with the center line, that is, The center line correction of the motion system can be achieved. The scale lines 19 are divided into two groups, one group has two values ​​for the X end, and the other group has three values ​​for the Y end. By rotating the pre-tightening bolt 16, the sleeve 27 is driven to rotate, and the sleeve 27 is rotated at the side end of the second mounting rod 12. At the same time, the pre-tightening bolt 16 moves toward the side end of the second mounting rod 12. At the same time, the spring 26 generates a pulling force on the engaging block 25, allowing the engaging block 25 to slide toward the inside of the sleeve 27. The side end of the pre-tightening bolt 16 drives the docking rod 24 to dock with the socket at the side end of the second mounting rod 12, limiting the reverse rotation of the pre-tightening bolt 16 and the sleeve 27 to prevent the pre-tightening bolt 16 from loosening. At the same time, by pulling the pre-tightening bolt 16, the pre-tightening bolt 16 is allowed to slide on the side end of the sleeve 27, allowing the pre-tightening bolt 16 to drive the docking rod 24 away from the side end of the second mounting rod 12, and then the sleeve 27 can be selected to rotate in the opposite direction.

[0032] Finally, it should be noted that the above embodiments are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
