Due to the weight of the dial indicator and the connecting rod, the connecting rod will have a large deflection, which in turn will lead to a large error in the alignment result. Summary of the Invention

[0004] This application aims to at least partially solve the technical problem of large errors in current concentricity detection devices. To this end, this application provides a display stand and a concentricity detection device.

[0005] In a first aspect, an embodiment of this application provides a mounting frame for installing a micrometer. The frame includes an upright plate, a crossbeam, and a diagonal brace.

[0031] This application is described below with reference to the accompanying drawings and specific embodiments:

[0032] Example 1

[0033] Please refer to Figures 1-3 This application discloses a gauge frame, including a vertical plate 100, a horizontal beam 200, and a diagonal tie beam 300. This gauge frame can be used in a concentricity testing device. Specifically, when a micrometer 400 is mounted on the gauge frame, it constitutes a concentricity testing device for measuring and aligning the concentricity of the coupling wheels of a transmission device.

[0034] Among them, the upright plate 100 is the basic component of the table frame of this application. The upright plate 100 can provide an installation base for at least some other components of the table frame. Therefore, since the upright plate 100 has the function of supporting at least some other components of the table frame, the upright plate 100 can be made of metal structural parts with a certain strength, so that the upright plate 100 and the components set on the upright plate 100 can remain stable and reliable.

[0035] The upright plate 100 is a plate-shaped structural member, which gives it two opposing plate surfaces, thus providing more reliable structural stability compared to rod-shaped structural members in related technologies.

[0036] One end of the crossbeam 200 is connected to the vertical plate 100. The crossbeam 200 is provided with a first mounting position 210 and a second mounting position 220. The micrometer 400 can be installed in both the first mounting position 210 and the second mounting position 220. The micrometer 400 is detachably mounted on the first mounting position 210 and / or the second mounting position 220. Therefore, one micrometer 400 or two micrometers 400 can be installed on the crossbeam 200. Thus, the concentricity detection device of the table frame of this application can be used in either single-tablet mode or double-tablet mode, and can be applied to different detection scenarios.

[0037] When only the first mounting position 210 on the crossbeam 200 is equipped with a micrometer 400, the alignment of the gears of the transmission equipment can be performed using a single-meter alignment method. Specifically, when the transmission equipment has a first gear 500 and a second gear 600, two gauge holders of this application can be used, and a micrometer 400 can be installed on each of the two gauge holders. The two gauge holders are fixed on the first gear 500 and the second gear 600 respectively. The pointer of the micrometer 400 on the gauge holder fixed on the first gear 500 is aligned with the circumferential outer wall of the second gear 600, and the pointer of the micrometer 400 on the gauge holder fixed on the second gear 600 is aligned with the circumferential outer wall of the first gear 500. In this way, the concentricity of the first gear 500 and the second gear 600 can be detected.

[0038] When micrometers 400 are installed at both the first mounting position 210 and the second mounting position 220 on the crossbeam 200, the coupling wheels of the transmission equipment can be aligned using a dual-micrometer alignment method. Specifically, a micrometer frame of this application can be used, and micrometers 400 are simultaneously installed at the first mounting position 210 and the second mounting position 220 of the crossbeam 200 of the micrometer frame. The micrometer frame is fixed on the first coupling wheel 500, and the pointers of the two micrometers 400 are aligned with the circumferential outer wall and the axial outer wall of the second coupling wheel 600, respectively. This allows for the detection of the concentricity of the first coupling wheel 500 and the second coupling wheel 600.

[0039] It should be understood that the micrometer 400 mentioned above can be a dial indicator or a micrometer, or other length measuring devices. The specific choice can be made according to the actual test conditions and accuracy requirements. This application does not limit the specific structure of the micrometer 400.

[0040] One end of the diagonal brace 300 is connected to the vertical plate 100, and the other end is connected to the horizontal beam 200. The vertical plate 100, the horizontal beam 200, and the diagonal brace 300 can form a triangular structure. The triangular structure has excellent structural stability, so the diagonal brace 300 can fix the horizontal beam 200, making the horizontal beam 200 stable. At the same time, the diagonal brace 300 can also support the horizontal beam 200 in the opposite direction of the horizontal beam 200's gravity, preventing the horizontal beam 200 from deflecting relative to the vertical plate 100 due to its own weight and the self-weight of the micrometer 400 set on the horizontal beam 200. This ensures that the test structure using the concentricity testing device of the table frame of this application is accurate.

[0041] In the formwork frame of this application embodiment, the upright plate 100 provides an installation base for the crossbeam 200. The first mounting position 210 and the second mounting position 220 on the crossbeam 200 can be used to mount the micrometer 400, and the micrometer 400 is detachably mounted on the first mounting position 210 and the second mounting position 220. This allows the concentricity testing device using the formwork frame of this application to perform concentricity testing using either a single-meter alignment method or a double-meter alignment method, thereby improving its applicability. The diagonal beam 300, the crossbeam 200, and the upright plate 100 form a triangular structure, giving the formwork frame of this application better structural strength. The diagonal beam 300 can support the crossbeam 200, thereby preventing the crossbeam 200 from deflecting relative to the upright plate 100 and causing deflection.

[0042] In some embodiments, the crossbeam 200 mentioned above can be configured to be perpendicular to the vertical plate 100. This creates a right-angled triangle structure formed by the vertical plate 100, crossbeam 200, and diagonal beam 300, resulting in better overall structural stability. Furthermore, when the crossbeam 200 is perpendicular to the vertical plate 100, it is easier to align the pointer of the micrometer 400 mounted on the crossbeam 200 with the vertical plate 100, thus facilitating the alignment of the transmission equipment's coupling wheels.

[0043] In some embodiments, the crossbeam 200 described above is provided with a first end 230 and a second end 240, which are arranged opposite to each other. The first end 230 is connected to the vertical plate 100, and the second end 240 is the end of the crossbeam 200 facing away from the vertical plate 100. The diagonal tie beam 300 has opposite third ends 310 and fourth ends 320. The third end 310 of the diagonal tie beam 300 is connected to the vertical plate 100, and the fourth end 320 of the diagonal tie beam 300 is connected to the crossbeam 200, located between the first end 230 and the second end 240 of the crossbeam 200. Thus, the diagonal tie beam 300 can support the crossbeam 200 in the position between the first end 230 and the second end 240, thereby better supporting the crossbeam 200 and keeping it stable.

[0044] Specifically, the extension line from the third end 310 to the fourth end 320 of the cable-stayed beam 300 can be set to pass through the center of gravity of the crossbeam 200. In this way, the fourth end 320 of the cable-stayed beam 300 can be supported at the center of the crossbeam 200, thereby making the stability of the crossbeam 200 better after the fourth end 320 of the cable-stayed beam 300 supports the crossbeam 200, and thus avoiding the deflection of the crossbeam 200 due to its own weight.

[0045] Meanwhile, the extension line from the third end 310 to the fourth end 320 of the cable tie beam 300 can also be configured to pass through the second mounting position 220. When the micrometer 400 is installed on the second mounting position 220, the micrometer 400 on the second mounting position 220 is located at the center of gravity of the crossbeam 200. In this way, the center of gravity of the crossbeam 200 is subjected to the greatest force of its own weight, and the fourth end 320 of the cable tie beam 300 supports the center of gravity of the crossbeam 200, thereby further preventing the crossbeam 200 from deflecting.

[0046] In some embodiments, in order to allow the first mounting position 210 and the second mounting position 220 to be distributed in an orderly manner on the crossbeam 200, the first mounting position 210 may be set at the second end 240 of the crossbeam 200, so that the first mounting position 210 and the second mounting position 220 have a certain distance, thereby reserving installation space for the micrometer 400 set at the first mounting position 210 and the micrometer 400 set at the second mounting position 220, and preventing mutual interference between the two micrometers 400.

[0047] Meanwhile, the first mounting position 210 can form a first projection on the vertical plate 100, and the second mounting position 220 can form a second projection on the vertical plate 100. There is a certain distance between the first projection and the second projection. In this way, the first mounting position 210 and the second mounting position 220 have a certain distance in the width direction of the crossbeam 200, so that the micrometer 400 located at the first mounting position 210 and the micrometer 400 located at the second mounting position 220 are staggered. In this way, the pointers of the two micrometers 400 can respectively contact the circumferential outer wall and the axial outer wall of the transmission equipment.

[0048] In some embodiments, the frame of this application further includes a first fixing member 410. The first mounting position 210 mentioned above can be configured as a first strip-shaped hole opened in the crossbeam 200. The micrometer 400 can be detachably mounted in the first strip-shaped hole through the first fixing member 410, thereby achieving the purpose of detachably mounting the micrometer 400 in the first mounting position 210. At the same time, due to the strip-shaped hole structure of the first strip-shaped hole, the first fixing member 410 can be fixed at various positions in the first strip-shaped hole, thereby achieving the purpose of adjusting the position of the tester mounted in the first mounting position 210.

[0049] Similarly, the second mounting position 220 can be configured as a second strip-shaped hole opened on the crossbeam 200, and the micrometer 400 can also be detachably mounted in the second strip-shaped hole via the first fixing member 410, thus allowing the position of the micrometer 400 located on the second mounting position 220 to be adjusted. When the positions of the micrometer 400 on the first mounting position 210 and the micrometer 400 on the second mounting position 220 are adjustable, the concentricity detection device using the gauge frame of this application can be applied to various transmission equipment of different specifications and sizes, thereby improving applicability.

[0050] In some embodiments, the extension directions of the first and second strip holes mentioned above are in the same direction as the direction from the first end 230 to the second end 240 of the crossbeam 200. Accordingly, the micrometer 400 provided in the first strip hole and the micrometer 400 provided in the second strip hole can both be adjusted in the direction from the first end 230 to the second end 240 of the crossbeam 200.

[0051] Specifically, when the distance between the first pair of wheels 500 and the second pair of wheels 600 of the transmission device to be tested is relatively large, after fixing the upright plate 100 to the first pair of wheels 500, the first fixing member 410 can be adjusted to the position of the second end 240 of the crossbeam 200 adjacent to the first and second strip holes, so that the distance between the micrometer 400 set on the first and second strip holes and the upright plate 100 is increased, thereby allowing the micrometer 400 to make corresponding contact with the second pair of wheels 600.

[0052] When the distance between the first pair of wheels 500 and the second pair of wheels 600 of the transmission device to be tested is relatively small, after fixing the upright plate 100 to the first pair of wheels 500, the first fixing member 410 can be adjusted to the position adjacent to the first end 230 of the crossbeam 200 in the first and second slots, so that the distance between the micrometer 400 set on the first and second slots and the upright plate 100 is reduced, thereby allowing the micrometer 400 to make corresponding contact with the second pair of wheels 600.

[0053] In some embodiments, to enable the gauge holder to be fixed to the coupling of the transmission device to be tested, the gauge holder of this application embodiment further includes a second fixing member 110. The second fixing member 110 is disposed on the upright plate 100 and can fix the upright plate 100 to the test piece. Specifically, the second fixing member 110 can be a bolt and a nut. A screw hole for the bolt to pass through can be opened on the upright plate 100. The bolt can pass through the screw hole on the upright plate 100 and through the through hole on the coupling, and then the upright plate 100 is fixed to the coupling with the nut. Fixing the upright plate 100 to the coupling with the first fixing member 410 can make the connection between the upright plate 100 and the coupling stable and reliable, thereby making the detection effect of the concentricity detection device using the gauge holder of this application more accurate and reliable.

[0054] In some embodiments, to improve the applicability of the concentricity detection device of the table frame of this application, the table frame of the present application embodiment may also be provided with an extension connector 120. The extension connector 120 is connected to the second fixing member 110. The extension connector 120 can increase the distance between the upright plate 100 and the pair of wheels used to install the upright plate 100, thereby reducing the distance between the upright plate 100 and the other pair of wheels.

[0055] Specifically, the extension connector 120 can adopt a sleeve structure. The extension connector 120 is sleeved on the bolt, and the two ends of the extension connector 120 abut against the upright plate 100 and the matching wheel, respectively. In this way, the extension connector 120 can increase the distance between the upright plate 100 and the matching wheel, thereby reducing the distance between the upright plate 100 and the other matching wheel, thus improving the applicability of the concentricity detection device of the table frame of this application.

[0056] Example 2

[0057] Based on the aforementioned micrometer frame, this application embodiment also proposes a concentricity detection device, including two micrometers 400 and the aforementioned micrometer frame. The two micrometers 400 are detachably mounted on the first mounting position 210 and the second mounting position 220 of the crossbeam 200, respectively. This allows the concentricity detection device to detect the concentricity of the transmission equipment wheels using both a single-micrometer alignment method and a double-micrometer alignment method.
