[0043] In this embodiment, the centering block seat 9 is connected to the housing 1 and the centering block 10 by the third bolt 13.

[0044] The following description will further illustrate the characteristics and functions of this utility model.

[0045] This embodiment aims to establish a machining benchmark by quickly locating the center of the track beam, thereby improving the quality and efficiency of track beam machining. A track beam centering device for skid steer loaders is provided, which can quickly and accurately locate the center of the track beam, greatly improving the quality and efficiency of track beam machining.

[0046] The main structure of the centering device in this embodiment is described below:

[0047] The structure of the track beam centering device for skid steer loaders is as follows: Figure 1 and Figure 2 The assembly shown consists of: housing 1, centering screw 2, centering shaft 3, rubber spring pad 4, flange cover 5, first bolt 6, support column 7, second bolt 8, centering block seat 9, and centering block 10 (where parts numbered 3 to 8 are symmetrical about the center plane of housing 1).

[0048] The centering screw 2 is threaded onto the top center of the housing 1. The centering shaft 3 is assembled inside the housing 1, and the rubber spring pad 4 is assembled inside the flange cover 5. The flange cover 5 is fixed to the side of the housing 1 by three first bolts 6 (model M5x20). The support column 7 is fixed to the outside of the centering shaft 3 by one second bolt 8 (model M8x20) (where parts numbered 3 to 8 are symmetrical about the center plane of the housing 1). The first connecting surface 91 of the centering block seat 9 is fixed to the front side of the housing 1 by two third bolts 13 (model M5x20). The inner surface 101 of the centering block 10 is fixed to the second connecting surface 92 of the centering block seat 9 by two third bolts 13 (model M5x20). After all assembly is completed, the outer surface 102 of the centering block 10 coincides with the center plane (i.e., the line of symmetry) of the housing 1.

[0049] The flange covers 5 on both sides are equipped with rubber spring pads 4. In addition to their sealing function, they can also automatically retract the centering shaft 3 under the elastic action of the rubber spring pads 4 after use and loosening of the centering screw 2.

[0050] The function and principle of the centering device in this embodiment are as follows:

[0051] Rotating the centering screw 2 causes it to move downwards, pushing the centering shaft 3 and causing the support column 7 to move outwards (due to left-right symmetry, the left and right sides move outwards synchronously by equal distances). This causes the outer surfaces of the support columns 7 on both sides to press firmly against the inner surface of the sliding track beam, fixing them in place. At this point, the outer surface 102 of the centering block 10 becomes the center surface of the track beam. This achieves the goal of quickly and accurately positioning the track beam center, improving the quality and efficiency of track beam machining.

[0052] In summary, the centering device of this invention can quickly and accurately locate the center of the track beam, thereby improving the quality and efficiency of track beam machining.

[0053] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
