Description

Technical Field

[0001] This utility model relates to the field of bearing saddle perpendicularity detection, specifically a bearing saddle inspection fixture structure. Background Technology

[0002] Bearing saddle perpendicularity gauges are primarily used to inspect the perpendicularity of the bearing saddle relative to a reference surface or other components, ensuring their precise positioning during assembly and operation. Currently used bearing saddle perpendicularity gauges are typically designed to contact the saddle surface, allowing direct display of perpendicularity deviation via a dial indicator. However, this type of gauge has a drawback: it can only inspect one face of the bearing saddle at a time. If inspecting different end faces requires multiple adjustments, each face must be inspected individually, increasing inspection time and cost. Furthermore, these multiple adjustments may cause misalignment of the bearing saddle, affecting the inspection results. Utility Model Content

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] Example 1

[0028] like Figures 1 to 2As shown, a bearing saddle inspection fixture structure is provided. This fixture structure overcomes the drawback of existing bearing saddles that can only be inspected on one side. Through this improved saddle inspection fixture structure, the perpendicularity of multiple end faces of the bearing saddle can be inspected at one time. The fixture structure includes a saddle fixture base 1. A horizontally positioned guide beam 11 is mounted on the top surface of the saddle fixture base 1. A limiting sliding block 12 is provided on one side of the horizontal positioning guide beam 11 to stably limit the bearing saddle on the saddle fixture base 1. A first dial indicator 2 is movably mounted on one side of the horizontal positioning guide beam 11. A first sensitive probe is mounted and connected to the first dial indicator 2 and is used to contact the surface of the bearing saddle. A second dial indicator 3 is movably mounted on one end of the horizontal positioning guide beam 11 away from the first dial indicator 2. A second sensitive probe is mounted and connected to the second dial indicator 3 and is used to contact the surface of the bearing saddle. A third dial indicator 4 is movably mounted on the other end of the horizontal positioning guide beam 12 away from the first dial indicator 2. A third sensitive probe is mounted and connected to the third dial indicator 4 and is used to contact the surface of the bearing saddle. The second dial indicator 3 and the third dial indicator 4 are movably mounted on the saddle fixture base 1.

[0029] In this embodiment, the bearing saddle to be inspected is placed on the saddle inspection fixture base 1, and one end face of the bearing saddle is placed against the horizontal positioning guide beam 11. Then, the bearing saddle is temporarily limited and stabilized on the saddle inspection fixture base 1 by adjusting the limiting sliding block 12. Then, by adjusting the first dial indicator 2, the first sensitive probe connected to the first dial indicator 2 is brought into contact with one end face of the bearing saddle, and the perpendicularity of that end face of the saddle fixture base 1 is determined by the reading on the first dial indicator 2. Similarly, by adjusting the second dial indicator 3, the second sensitive probe connected to the second dial indicator 3 is brought into contact with one side end face of the bearing saddle, and the perpendicularity of that side end face of the saddle fixture base 1 is determined by the reading on the second dial indicator 3. Likewise, by adjusting the third dial indicator 4, the third sensitive probe connected to the third dial indicator 4 is brought into contact with the other side end face of the bearing saddle, and the perpendicularity of that side end face of the saddle fixture base 1 is determined by the reading on the third dial indicator 4. Thus, this fixture structure enables the measurement of the perpendicularity of multiple sides of the bearing saddle.

[0030] Example 2

[0031] Based on Embodiment 1, the first micrometer 2 is movably connected to the saddle fixture base 1 via a first movable adjustment structure. The first movable adjustment structure includes a first telescopic rod that can be raised and lowered. One end of the first telescopic rod is rotatably connected to the first micrometer 2 via a bearing, and the other end is retractably mounted on a first sliding block 21. A first movable support block 22 is provided at the bottom of the first sliding block 21, and a groove is provided at the top of the first movable support block 22. The first sliding block 21 and the groove at the top of the first movable support block 22 are slidably adapted to each other. A first movable rod is connected to the bottom of the first movable support block 22, and a first movable limiting groove is provided on the saddle fixture base 1. The first movable rod is movably adapted to the first movable limiting groove and can slide horizontally along the first movable limiting groove and the saddle fixture base 1. With this configuration, the first micrometer 2 and the first sensitive probe mounted on and connected to it can move freely along the X, Y, and Z axes, enabling measurement of any position on the end face of the bearing saddle.

[0032] Example 3

[0033] Furthermore, the second micrometer 3 is movably connected to the saddle fixture base 1 via a second movable adjustment structure. The second movable adjustment structure includes a horizontally telescopic second telescopic rod. One end of the second telescopic rod is rotatably connected to the second micrometer 3 via a bearing, and the other end of the second telescopic rod is telescopically mounted on the second sliding block 31. The end of the second sliding block 31 away from the second micrometer 3 is connected to the second movable support block. The second movable support block is slidably adapted to the second movable support column 32 and can be moved up and down along the second movable support column 32. The bottom end of the second movable support column 32 is horizontally slidably connected to the saddle fixture base 1.

[0034] Similarly, the third micrometer 4 is movably connected to the saddle fixture base 1 via a third movable adjustment structure. The third movable adjustment structure includes a horizontally telescopic third telescopic rod. One end of the third telescopic rod is rotatably connected to the third micrometer 4 via a bearing, and the other end is telescopically connected to the third sliding block 41. The end of the third sliding block 41 furthest from the third micrometer 4 is connected to a third movable support block. The third movable support block is slidably fitted onto a third movable support column 42 and can move up and down along the third movable support column 42. The bottom end of the third movable support column 42 is horizontally slidable with the saddle fixture base 1, and the third movable support column 42 and the second movable support column 32 can slide relative to each other along the saddle fixture base 1.

[0035] The second dial indicator 3 and the third dial indicator 4, configured in this way, can move freely along the X, Y, and Z axes in space. The second dial indicator 3 drives the second sensitive probe connected to it to measure one end face of the bearing saddle. Simultaneously, the third dial indicator 4 drives the third sensitive probe connected to it to measure the other end face of the bearing saddle. The end face of the bearing saddle facing away from the first dial indicator 2 can be measured using either the second dial indicator 3 or the third dial indicator 4. It should be noted that, in practice, more second dial indicators 3 that can move up and down along the second movable support column 32, and more third dial indicators 4 that can move up and down along the third movable support column 42, can be added to meet the measurement needs.

[0036] Ultimately, the improved saddle fixture structure enables the perpendicularity inspection of multiple end faces of the bearing saddle in a single operation. This not only improves inspection efficiency and saves inspection time, but also avoids the potential shift in the bearing saddle position caused by multiple adjustments, thus ensuring the accuracy of the inspection results.
