Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a pneumatic measuring instrument for blade measurement, comprising a frame 1, a conveyor belt 2 is arranged inside the frame 1, and a U-shaped frame 3 is symmetrically installed on the top of the frame 1, wherein:

[0024] A U-shaped probe 4 is installed on the inner top of the U-shaped frame 3, a pneumatic measuring instrument 5 is installed on the top of the U-shaped frame 3, a bracket 6 is installed equidistantly on the outer side of the conveyor belt 2, a support 7 is rotatably connected to the middle of the bracket 6, a blade 8 is installed on the top of the support 7, and the blade 8 is installed on the support 7 through a clamping mechanism;

[0025] A gear rod 15 is installed on the side wall of the frame 1 between the U-shaped frames 3, and a transmission tooth 16 is fixedly connected to the ring side of the support 7 corresponding to the gear rod 15 at equal distances, and a limit frame 17 is fixedly connected to the bottom of the support 7 near the ring side, and a guide frame 18 is symmetrically installed on the inner wall of the frame 1 at the U-shaped frame 3;

[0026] When it is necessary to measure the blade 8, the blade 8 is limited at the top of the support 7 by the clamping mechanism, and the blade 8 is driven to move toward the first U-shaped frame 3 by the conveyor belt 2. When the blade 8 passes the first U-shaped probe 4, the width of the blade 8 is measured by the U-shaped probe 4 and the pneumatic measuring instrument 5. Then the blade 8 continues to move. When the support 7 moves to the gear rod 15, the gear rod 15 is engaged with the transmission tooth 16, so that the support 7 drives the blade 8 to rotate 90°, and then the blade 8 passes the second U-shaped probe 4 to measure the thickness of the blade 8. The pneumatic measuring instrument 5 used for measuring the blade 8 can quickly complete the measurement of the size of the blade 8, effectively improving the measurement efficiency of the blade 8.

[0027] See also Figures 1 to 4The clamping mechanism includes a fixing frame 9, and the fixing frames 9 are symmetrically fixedly connected to the top of both sides of the support 7. The fixing frame 9 is penetrated by a guide rod groove 10, and a guide rod 11 is penetrated in the guide rod groove 10. A clamping frame 12 is fixedly connected to one end of the guide rod 11 close to the blade 8, and an anti-skid pad 13 is installed on the side of the clamping frame 12 close to the blade 8. A spring 14 is sleeved on the guide rod 11 between the clamping frame 12 and the fixing frame 9. The guide rod 11 is a rectangular column, and the external size of the guide rod 11 coincides with the internal size of the guide rod groove 10. When the blade 8 needs to be clamped, the blade 8 is placed between the clamping frames 12, and the clamping frame 12 is tightly pressed against the side of the blade 8 through the spring 14. The friction between the clamping frame 12 and the blade 8 is increased by the anti-skid pad 13, so as to facilitate the clamping and fixing of the blade 8, avoid the shaking of the blade 8 during measurement, and facilitate the measurement of the blade 8.

[0028] See also Figures 1 to 4 The tooth pitch of the gear rod 15 is equal to the tooth pitch of the transmission tooth 16, the outer surface of the limit frame 17 is octagonal, and the width of the limit frame 17 coincides with the spacing between the guide frames 18. When the support 7 drives the blade 8 to pass through the inner side of the U-shaped frame 3 and the blade 8 is measured, the movement of the support 7 is limited by the guide frame 18 and the limit frame 17 to prevent the blade 8 from rotating when passing through the inner side of the U-shaped frame 3, so that the blade 8 can move vertically, thereby improving the accuracy of measuring the blade 8.

[0029] Working principle: This pneumatic measuring instrument for blade measurement, when it is necessary to measure the blade 8, the blade 8 is limited at the top of the support 7 by the clamping mechanism, and the blade 8 is driven to move toward the first U-shaped frame 3 by the conveyor belt 2. When the blade 8 passes the first U-shaped probe 4, the width of the blade 8 is measured by the U-shaped probe 4 and the pneumatic measuring instrument 5. Then the blade 8 continues to move. When the support 7 moves to the gear rod 15, the gear rod 15 is meshed with the transmission tooth 16, so that the support 7 drives the blade 8 to rotate 90°, and then the blade 8 passes the second U-shaped probe 4 to measure the thickness of the blade 8. The pneumatic measuring instrument 5 for measuring the blade 8 can quickly complete the measurement of the size of the blade 8. The measurement efficiency of the blade 8 is effectively improved, and when the blade 8 needs to be clamped, the blade 8 is placed between the clamping frames 12, and the clamping frames 12 are tightly pressed against the side of the blade 8 through the spring 14. The clamping frames 12 increase the friction between the blade 8 and the blade 8 through the anti-slip pad 13, thereby facilitating the clamping and fixing of the blade 8, avoiding the shaking of the blade 8 during measurement, and facilitating the measurement of the blade 8. The support 7 drives the blade 8 to pass through the inner side of the U-shaped frame 3. When the blade 8 is measured, the movement of the support 7 is limited by the guide frame 18 and the limit frame 17, avoiding the rotation of the blade 8 when passing through the inner side of the U-shaped frame 3, so that the blade 8 can move vertically, thereby improving the accuracy of the measurement of the blade 8.
