[0028] The following further describes the present utility model in conjunction with specific implementation cases and attached Figures 1 to 4 drawings, but the present utility model is not limited to these embodiments.

[0029] Referring to Figures 1 to 4 as shown, an outer diameter dimension measuring device includes a bracket 1, a first upright post 2 is vertically installed on the bracket 1, a first connecting seat 3 is fixedly installed at the top of the first upright post 2, mounting plates 4 are fixedly and vertically installed on the right side and the rear side of the first connecting seat 3 respectively, scales 5 are arranged on each mounting plate 4, and the starting scales of the two scales 5 are respectively in contact with the right side wall and the rear side wall of the first connecting seat 3. A first moving frame 6 is slidably sleeved on the scale 5 arranged in the front-rear direction, a first through slot 7 is formed in the first moving frame 6 from front to back, and the first through slot 7 is sleeved on the scale 5 arranged in the front-rear direction. A second moving frame 8 is slidably sleeved on the scale 5 arranged in the horizontal direction, a second through slot 9 is formed in the second moving frame 8 from left to right, and the second through slot 9 is sleeved on the scale 5 arranged in the horizontal direction; wherein, the first moving frame 6 is slidably embedded in the inner cavity of the second through slot 9, so as to ensure that the first moving frame 6 can move along the second moving frame 8, and the movements of the two do not interfere with each other;

[0030] By moving the mounting plate 4 and the scale 5 arranged horizontally through the second moving frame 8 and the second through groove 9, it is possible to cause the second moving frame 8 to displace relative to the scale 5 arranged horizontally, so as to display the distance between the first connecting seat 3 and the left edge of the second moving frame 8. The distance between the starting scale of the horizontally arranged scale 5 and the left edge of the second moving frame 8 is the size of the horizontal outer diameter of the component. By moving the mounting plate 4 and the scale 5 arranged in the front-back direction through the first moving frame 6 and the first through groove 7, it is possible to cause the first moving frame 6 to displace relative to the scale 5 arranged in the front-back direction, so as to display the distance between the first connecting seat 3 and the front edge of the first moving frame 6. The distance between the starting scale of the front-back direction scale 5 and the front edge of the first moving frame 6 is the size of the front-back outer diameter of the component.

[0031] For main reference Figure 2 As shown, a second upright post 10 is vertically installed on the bracket 1. A second connecting seat 11 is fixedly installed at the top of the second upright post 10. Support arms 12 are fixedly and vertically installed on the right side and the rear side of the second connecting seat 11 respectively. Through the second upright post 10 and the second connecting seat 11, support can be provided for the two support arms 12.

[0032] For main reference Figure 2 and Figure 3 As shown, guiding components are respectively arranged on the two support arms 12. The guiding component includes a groove body 13 opened on the upper surface of the support arm 12. A first limiting rod 14 is installed in the groove body 13. A moving block 15 is slidably sleeved on the first limiting rod 14, and the moving block 15 is slidably embedded in the inner cavity of the groove body 13. A connecting block 16 is fixedly installed at the top of the moving block 15. The connecting block 16 on the left side is connected to the side wall of the first moving frame 6, and the connecting block 16 on the front side is connected to the side wall of the second moving frame 8, so as to ensure that both the first moving frame 6 and the second moving frame 8 can be effectively limited. Two sets of mounting seats 17 are vertically installed on each support arm 12. A second limiting rod 18 is installed between the two mounting seats 17, and the connecting block 16 is slidably sleeved on the second limiting rod 18. When the connecting block 16 moves, it can move along the corresponding second limiting rod 18, and cause the moving block 15 installed at the bottom of the connecting block 16 to move along the outer wall of the first limiting rod 14. Thus, it is ensured that both the moving block 15 and the connecting block 16 can move stably without skewing, and further ensure that during the moving process, the second moving frame 8 and the first moving frame 6 can always move vertically relative to the scales 5 at their respective corresponding positions.

[0033] In addition, for main reference Figure 3 As shown, a vertical rod 25 is installed on the outer side wall of the connecting block 16. It is easier to drive the connecting block 16 to move by moving the vertical rod 25.

[0034] For main reference Figures 2 to 4As shown in the figure, a base 19 is provided below the bracket 1, and a height adjustment component is provided on the base 19; the height adjustment component includes a first fixing block 20 fixedly installed on the side wall of the bracket 1, and further includes a lead screw 21 rotatably provided on the base 19, and the first fixing block 20 is threadedly sleeved on the lead screw 21. A second fixing block 23 is also installed on the side wall of the bracket 1, and a dial rod 24 is installed on the base 19, and the dial rod 24 penetrates through the outer wall of the second fixing block 23. A hand wheel 22 is installed at the top of the lead screw 21. Rotating the hand wheel 22 drives the lead screw 21 to rotate synchronously, prompting the first fixing block 20 to move vertically along the lead screw 21, thereby prompting the bracket 1 to drive the two second fixing blocks 23 to move vertically along the corresponding dial rods 24, thereby adjusting the height of the bracket 1, that is, adjusting the height of the first moving frame 6 and the second moving frame 8 installed on the bracket 1, ensuring that the side wall of the component placed on the upper surface of the base 19 can adapt to the side wall height of the adjusted first moving frame 6 and the second moving frame 8, and prompting the side walls of the first moving frame 6 and the second moving frame 8 to accurately fit the side wall height of the component.

[0035] The working principle of an outer diameter dimension measuring device in this embodiment is as follows:

[0036] Place the component to be measured in the hollow space formed by the two mounting plates 4, the first moving frame 6, and the second moving frame 8. When measuring the outer diameter in the horizontal direction, drive the vertical rod 25 at the front side to drive the corresponding connecting block 16 and the second moving frame 8 to move to the left synchronously. The second through groove 9 at the second moving frame 8 moves to the left along the mounting plate 4 and the scale 5 arranged in the horizontal direction until the left side wall of the second moving frame 8 fits the right side wall of the component. At this time, the distance between the starting scale of the horizontal scale 5 and the left side wall of the second moving frame 8 is the length of the horizontal outer diameter of the component; similarly, when measuring the outer diameter in the front-back direction, drive the left vertical rod 25 to drive the connecting block 16 and the first moving frame 6 to move forward synchronously. The first through groove 7 at the first moving frame 6 moves forward along the mounting plate 4 and the scale 5 arranged in the front-back direction. Finally, the distance between the starting scale of the front-back scale 5 and the front side wall of the first moving frame 6 is the length of the front-back outer diameter of the component; thus, the measurement of the horizontal and front-back outer diameters of the component is realized.

[0037] When the connecting block 16 moves, it can move along the corresponding second limiting rod 18, and prompt the moving block 15 installed at the bottom of the connecting block 16 to move along the outer wall of the first limiting rod 14, thereby ensuring that both the moving block 15 and the connecting block 16 can move stably without skewing, and further ensuring that during the moving process, the second moving frame 8 and the first moving frame 6 can always move vertically relative to the scales 5 at their respective corresponding positions.

[0038] When the height of the component changes, rotate the handwheel 22 to drive the lead screw 21 to rotate synchronously, prompting the first fixed block 20 to move vertically along the lead screw 21, thereby prompting the bracket 1 to drive the two second fixed blocks 23 to move vertically along the corresponding position of the lever 24, thereby adjusting the height of the bracket 1, that is, adjusting the height of the first moving frame 6 and the second moving frame 8 installed on the bracket 1, ensuring that the side wall of the component placed on the upper surface of the base 19 can adapt to the adjusted side wall height of the first moving frame 6 and the second moving frame 8, and prompting the side wall of the first moving frame 6 and the second moving frame 8 to accurately fit the side wall height of the component;

[0039] The utility model does not need to re - arrange the reference points. When performing horizontal and front - back direction measurements, they do not interfere with each other and can be carried out synchronously, avoiding human errors caused by re - arranging the reference points. The measurement results are more accurate and consistent, and the device can adapt to components of different heights, meeting the requirements for measuring the outer diameters of components of different heights.
