[0013] The present invention also discloses a high-precision stainless steel casting thickness measurement method, which uses the above-mentioned high-precision stainless steel casting thickness measuring device, and comprises the following steps:

[0014] S1. First, when testing the stainless steel casting, the stainless steel casting is first placed on the support plate, and then the movable ring located on the right side of the stainless steel casting is pushed to move toward the disc, so that the connecting seat is pushed to contact the clamping plate through the sliding rod, so that the clamping plate is rotated ninety degrees and fits the outer wall of the stainless steel casting, so as to fix the stainless steel casting. Since the distance between the first laser measuring instrument and the second laser measuring instrument is fixed, the thickness of the stainless steel casting can be obtained by subtracting the values ​​measured by the first laser measuring instrument and the second laser measuring instrument from the distance between the first laser measuring instrument and the second laser measuring instrument. When a position After the thickness measurement of the device is completed, the second drive motor is started intermittently, and the output end of the second drive motor drives the disc to drive the stainless steel casting to rotate in a circle, so as to detect different positions of the stainless steel casting, and the first drive motor is started, and the output end of the first drive motor is started and stopped intermittently, and the output end of the first drive motor drives the one-way threaded screw to rotate, thereby driving the sliding seat to drive the stainless steel casting to move laterally intermittently, so as to cooperate with the circumference measurement of the stainless steel casting to realize the full-scale thickness measurement of the stainless steel casting, without the need for the staff to measure manually one by one, which can improve the efficiency and accuracy of the measurement, and at the same time improve the overall practicality of the device;

[0015] S2. When the stainless steel casting is fixed, the movable ring is pushed to move toward the disc, so that the roller pushes the clamping plate to rotate 90 degrees. When the clamped part is uneven, the second movable rods can be adaptively pressed against the outer wall of the stainless steel casting under the action of the power spring, thereby improving the clamping stability and ensuring that the stainless steel casting will not shake during the rotation detection process, thereby ensuring the accuracy of the measurement;

[0016] S3, after the clamping plate rotates 90 degrees, it continues to push the movable ring to move, thereby driving the transmission rod driven by the second spur gear to rotate in a circle through the third spur rack, and then driving the multiple groups of arc-shaped clamping plates to clamp the outer wall of the connecting column under the action of positive thread and negative thread, so as to tighten the second movable rod after adaptive clamping, thereby improving the stability of clamping;

[0017] S4, when the movable ring at the right end of the stainless steel casting moves laterally to push the clamping plate to rotate, when the movable ring stops at a specified position, the fixing hole is aligned with the latch, so that the latch is reset and inserted into the fixing hole under the action of the auxiliary spring, thereby fixing the movable ring;

[0018] S5. The elastic coefficient of the second connecting spring is greater than the elastic coefficient of the first connecting spring. When the first laser measuring instrument and the second laser measuring instrument complete the measurement of the thickness of the stainless steel casting located at the left side during the transverse process of the stainless steel casting, when the sliding seat continues to move transversely, the first movable rod contacts the movable ring located at the left end of the stainless steel casting. During the process of continuing to move transversely, the movable ring is pushed by the resistance of the second connecting spring to move the movable ring located at the left end of the stainless steel casting, so that the clamping plate located at the left end of the stainless steel casting can be clamped on the outer wall of the stainless steel casting. The movable ring located at the left end of the stainless steel casting drives the first straight rod through the connecting ring while moving. The rack moves laterally, and then drives the second spur rack through the first spur gear to drive the fixed ring to move in the direction of the pin, so that the inclined surface at one end of the trapezoidal block contacts the spherical rod, thereby pushing the spherical rod to drive the pin to move away from the sliding rod. When the movable ring at the left end of the stainless steel casting stops moving, the pin at the right end of the stainless steel casting moves out from the inside of the sliding rod, so that the movable ring at the right end of the stainless steel casting is no longer fixed, and then the clamping plate can automatically reset under the action of the torsion spring and no longer block the side of the stainless steel casting, thereby realizing the switching of the clamping part of the stainless steel casting so that the thickness of the stainless steel casting can be measured in all directions.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By setting the clamp and the auxiliary measuring mechanism, first, when the stainless steel casting needs to be inspected, the stainless steel casting can be placed on the support plate first, and then the movable ring on the right side of the stainless steel casting can be pushed to move toward the disc, so that the connecting seat is pushed to contact the clamping plate through the sliding rod, so that the clamping plate is rotated ninety degrees and fits the outer wall of the stainless steel casting, so as to fix the stainless steel casting. Since the distance between the first laser measuring instrument and the second laser measuring instrument is fixed, the thickness of the stainless steel casting can be obtained by subtracting the value measured by the first laser measuring instrument and the second laser measuring instrument from the distance between the first laser measuring instrument and the second laser measuring instrument. After the thickness measurement of one position is completed, the second drive motor is started intermittently, and the output end of the second drive motor drives the disc to drive the stainless steel casting to rotate in a circle, so as to detect different positions of the stainless steel casting, and the first drive motor is started, and the output end of the first drive motor can be started and stopped intermittently, and the output end of the first drive motor drives the one-way threaded screw to rotate, thereby driving the sliding seat to drive the stainless steel casting to move horizontally intermittently, so as to cooperate with the circumference measurement of the stainless steel casting to realize the full-scale thickness measurement of the stainless steel casting, without the need for the staff to measure manually one by one, which can improve the efficiency and accuracy of the measurement, and at the same time improve the overall practicality of the device;

[0021] 2. By setting an adaptive resistance piece, when the stainless steel casting needs to be fixed, the movable ring is pushed to move toward the disc, so that the roller pushes the clamping plate to rotate 90 degrees. When the clamped part is uneven, the multiple second movable rods can be adaptively pressed against the outer wall of the stainless steel casting under the action of the power spring, thereby improving the clamping stability, thereby ensuring that the stainless steel casting will not shake during the rotation detection process, thereby ensuring the accuracy of the measurement;

[0022] 3. By arranging the cooperation of parts such as the transmission rod, when the clamping plate rotates 90 degrees, it continues to push the movable ring to move, so that the transmission rod driven by the second spur gear is driven by the third spur rack to rotate in a circle, and then drives multiple sets of arc clamping plates to clamp on the outer wall of the connecting column under the action of positive thread and negative thread, so as to tighten the second movable rod after adaptive clamping, thereby improving the stability of clamping;

[0023] 4. By setting an auxiliary switching part, the elastic coefficient of the second connecting spring is greater than the elastic coefficient of the first connecting spring. When the first laser measuring instrument and the second laser measuring instrument complete the thickness measurement of the stainless steel casting located at the left side during the lateral movement of the stainless steel casting, the first movable rod contacts the movable ring located at the left end of the stainless steel casting when the sliding seat continues to move lateral. The movable ring is pushed to move by the resistance of the second connecting spring during the lateral movement, so that the clamping plate at the left end of the stainless steel casting can be clamped on the outer wall of the stainless steel casting, and the movable ring at the left end of the stainless steel casting is connected to the movable rod while moving. The ring drives the first spur rack to move laterally, and then drives the second spur rack through the first spur gear to drive the fixed ring to move in the direction of the pin, so that the inclined surface at one end of the trapezoidal block contacts the spherical rod, thereby pushing the spherical rod to drive the pin to move away from the sliding rod. When the movable ring at the left end of the stainless steel casting stops moving, the pin at the right end of the stainless steel casting moves out from the inside of the sliding rod, so that the movable ring at the right end of the stainless steel casting is no longer fixed, and then the clamping plate can automatically reset under the action of the torsion spring and no longer block the side of the stainless steel casting, thereby realizing the switching of the clamping position of the stainless steel casting, so that the thickness of the stainless steel casting can be measured in all directions.

When a position After the thickness measurement is completed, the second drive motor 11 is started intermittently, and the output end of the second drive motor 11 drives the disc 19 to drive the stainless steel casting to rotate in a circle, so as to detect different positions of the stainless steel casting, and the first drive motor 4 is started, and the output end of the first drive motor 4 is started and stopped intermittently, and the output end of the first drive motor 4 drives the one-way threaded screw 6 to rotate, thereby driving the sliding seat 7 to drive the stainless steel casting to move laterally intermittently, so as to cooperate with the circumferential measurement of the stainless steel casting to realize the full-dimensional thickness measurement of the stainless steel casting, without the need for the staff to measure manually one by one, which can improve the efficiency and accuracy of the measurement, and at the same time improve the overall practicality of the device;

[0046] S2. When the stainless steel casting is fixed, the movable ring 23 is pushed to move toward the disk 19, so that the roller 30 pushes the clamping plate 21 to rotate 90 degrees. When the clamped part is uneven, the second movable rods 37 can be adaptively pressed against the outer wall of the stainless steel casting under the action of the power spring 38, thereby improving the clamping stability, thereby ensuring that the stainless steel casting will not shake during the rotation detection process, thereby ensuring the accuracy of the measurement;

[0047] S3. After the clamping plate 21 rotates 90 degrees, it continues to push the movable ring 23 to move, thereby driving the transmission rod 48 driven by the second spur gear 47 to rotate in a circle through the third spur rack 31, and then driving the multiple sets of arc clamping plates 39 to clamp on the outer wall of the connecting column 36 under the action of the positive thread and the negative thread, so as to tighten the second movable rod 37 after adaptive clamping, thereby improving the stability of clamping;

[0049] S5. The elastic coefficient of the second connecting spring 40 is greater than the elastic coefficient of the first connecting spring 22. When the first laser measuring instrument 2 and the second laser measuring instrument 3 complete the thickness measurement of the stainless steel casting located at the left side during the lateral movement of the stainless steel casting, the first movable rod 10 contacts the movable ring 23 located at the left end of the stainless steel casting when the sliding seat 7 continues to move lateral. The movable ring 23 is pushed to move by the resistance of the second connecting spring 40 during the lateral movement, so that the clamping plate 21 located at the left end of the stainless steel casting can be clamped on the outer wall of the stainless steel casting. The movable ring 23 located at the left end of the stainless steel casting drives the first straight rack 1 through the connecting ring 17 while moving. 2 is moved laterally, and then the second spur rack 14 is driven by the first spur gear 13 to drive the fixed ring 15 to move in the direction of the latch 26, so that the inclined surface of one end of the trapezoidal block 43 contacts the spherical rod 44, thereby pushing the spherical rod 44 to drive the latch 26 to move away from the sliding rod 18. When the movable ring 23 at the left end of the stainless steel casting stops moving, the latch 26 at the right end of the stainless steel casting moves out from the inside of the sliding rod 18, so that the movable ring 23 at the right end of the stainless steel casting is no longer fixed, and then the clamping plate 21 can automatically reset under the action of the torsion spring 34 and no longer block the side of the stainless steel casting, thereby realizing the switching of the clamping position of the stainless steel casting, so that the stainless steel casting can be measured in all directions.
