The base 1 is provided with an adjusting threaded hole 11, a slide table 12, a positioning post 13, and a fixing platform 14. The slider 2 is slidably disposed on the slide table 12. The adjusting push rod 3 has a threaded section that mates with the adjusting threaded hole 11, and one end of the adjusting push rod 3 abuts against the slider 2. The limiting block 4 is placed above the fixing platform 14, and the limiting block 4 is provided with a receiving hole 41 and a mounting hole 42. The mounting hole 42 is located on one side of the receiving hole 41 and communicates with the receiving hole 41. The thrust gauge 5 is mounted on the slider 2, and the push pin 51 of the thrust gauge 5 abuts against the limiting block 4. In this embodiment, the slider 2 has a mounting cavity 21, and the thrust gauge 5 is mounted in the mounting cavity 21.

[0063] Specifically, the base 1 has a boss 15, which is located on the side of the slide 12 away from the fixed platform 14. The adjusting threaded hole 11 is provided on the boss 15. It is easy to understand that the adjusting threaded hole 11 is a threaded through hole.

[0064] The fixed platform 14 is provided with a contour positioning groove 141. Optionally, the fixed platform 14 is provided with a relief groove 142 on the side near the positioning post 13. The relief groove 142 is connected to the contour positioning groove 141.

[0065] To facilitate assembly personnel operation, a knob 31 is fixedly provided at the end of the adjusting push rod 3 away from the slider 2.

[0066] The sliding direction of the slider 2 is consistent with the axial direction of the adjusting push rod 3.

[0067] In a preferred embodiment, the slide table 12 is provided with a slide groove 121, and the slider 2 is provided with a slide bar 22 adapted to the slide groove 121. Of course, it is also possible to provide a slide groove 121 on the slider 2 and a slide bar 22 on the slide table 12.

[0068] The bottom of the limiting block 4 is provided with multiple support feet 43. Some or all of the bottom surfaces of the support feet 43 contact the fixing plate 74 of the power source. When only a portion of the bottom surfaces of the support feet 43 contact the fixing plate 74 of the power source, the bottom surfaces of the remaining support feet 43 contact the fixing platform 14. In this embodiment, each corner of the limiting block 4 is provided with a corresponding support foot 43.

[0069] In one or more embodiments, the outer wall of the limiting block 4 is provided with a locking screw hole communicating with the receiving hole 41, and a locking screw 6 is provided at the locking screw hole.

[0070] Please combine Figure 1 , Figure 4 and Figure 5 The usage process of this belt tensioning fixture is briefly described as follows:

[0071] The spindle 73 and the motor 71 are respectively mounted on the fixed plate 74. The motor 71 is fixed to the fixed plate 74 by only one pre-fixing screw 75. The two ends of the belt 72 are respectively sleeved on the output shafts of the spindle 73 and the motor 71, thereby obtaining a pre-installed power source.

[0072] The spindle 73 with the pre-installed power source is fitted onto the positioning post 13. The fixing plate 74 is adjusted so that a portion of the fixing plate 74 is engaged in the contour positioning groove 141 of the fixing table 14. Then, the limiting block 4 is fitted onto the outside of the motor 71 using the receiving hole 41 (at this time, the mounting hole 42 on the limiting block 4 exposes the locking hole 741 of the fixing plate 74 and the strip-shaped locking hole 711 on the motor 71 corresponding to the locking hole 741). Figure 5 (As shown).

[0073] Rotating the adjusting push rod 3 causes it to contact the slider 2, bringing it closer to the limiting block 4 along the slide groove 121. This causes the push pin 51 of the thrust gauge 5 to gradually approach the limiting block 4 and continuously contact the side wall of the limiting block 4 until the pointer of the thrust gauge 5 reaches the preset value. During this process, the limiting block 4 causes the motor 71 to move slightly, causing the output end of the motor 71 to pull the belt 72 to tension (the main shaft 73 is limited by the positioning pin 13, so the main shaft 73 cannot move) to the standard value.

[0074] Finally, screw in the screws to lock the exposed strip-shaped lock hole 711 of the mounting hole 42 to the locking hole 741.

[0075] In summary, the belt tensioning fixture provided by this utility model has a simple and novel structure, low manufacturing cost, easy operation, and high assembly efficiency. Assemblers can visually adjust the belt tension through a thrust gauge and lock the motor, thereby ensuring consistent belt tension.

[0076] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
