Description

Technical Field

[0001] The present application relates to the technical field of turret detection, and in particular to a turret detection device with automatically adjustable angle. Background Art

[0002] The turret, also known as a CNC turret machine or a turret CNC lathe, is a high-precision, high-efficiency automated machine tool. The CNC turret is a CNC machine tool that integrates milling, drilling, tapping and other functions. It mainly realizes the processing of complex workpieces through programming and has a high degree of automated processing capabilities. In order to ensure the processing accuracy of CNC workpieces and improve the processing quality of workpieces, it is necessary to inspect the turret before or after the work is completed. The turret inspection usually includes tool locking accuracy inspection, tool holder mounting surface accuracy inspection and tool disc positioning groove accuracy inspection, etc. Among the many inspection items, tool repeat positioning accuracy inspection is an indispensable step in turret inspection.

[0003] For example, the patent with authorization announcement number CN206702239U discloses a fixture for detecting a turret, including a base, a turret housing, a detection device and a turret. The eight surfaces of the turret are detected in turn through a detection fixture arranged on the turret housing and a hydraulic device for fixing the turret. With the fixation of the hydraulic device, the detection of the turret is more accurate.

[0004] Although the above device realizes the detection of the turret, due to the diversity of workpieces, there are many different forms of CNC turrets used for processing workpieces. Usually, turrets are divided into two categories: straight rails and inclined rails. When processing more complex parts, an inclined rail turret is required. In order to flexibly adjust the cutting direction and cutting depth of the tool, the inclined rail turret needs to be continuously adjusted in the working process. However, when detecting the inclined rail turret, if the angle of the turret installed on the detection fixture cannot be adjusted, it will affect the accuracy of the turret detection. Therefore, it is necessary to provide a turret detection device with automatically adjustable angle to solve the above problem.

[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0035] Embodiment 1: This embodiment mainly introduces the basic structure and working principle of the turret detection device, specifically:

[0036] like Figure 1-Figure 3 As shown, the present application provides a turret detection device with automatically adjustable angle, including a base 1, which is a support part of the turret detection device, and provides support for the turret detection operation to ensure the smooth progress of the turret detection operation. The interior of the base 1 is hollow and has an upward opening. A support plate 21 is rotatably connected to the base 1 through a bearing, and a mounting platform 2 is fixedly mounted on the support plate 21. The mounting platform 2 is mainly used to install and fix the turret;

[0037] A hydraulic rod 6 is fixedly installed at the bottom of the base 1, and the output end of the hydraulic rod 6 is fixedly connected to the bottom of the support plate 21 to provide support for the support plate 21. In this way, the installation platform 2 can be supported and fixed by the hydraulic rod 6;

[0038] A detection member 4 is fixedly installed on the top of the installation platform 2. The detection member 4 is the existing turret to be detected. The detection member 4 includes a tower body 41 fixedly installed on the top of the installation platform 2. The tower body 41 is the main part of the turret. A driving motor 42 is fixedly installed on one side of the tower body 41. At the same time, a transmission mechanism (not shown in the figure) is arranged inside the tower body 41. The output end of the driving motor 42 is connected to one end of the transmission mechanism. A tower seat 43 is movably connected to the other side of the tower body 41 through a bearing. The tower seat 43 is connected to the other end of the transmission structure. The tower seat 43 is mainly used to install CNC tools. A plurality of groups of tool installation grooves (not marked in the figure) are arranged on the tower seat 43. The CNC tools are installed in the tool installation grooves. Figure 4 as well as Figure 6 A detection surface 431 is provided on the tool installation groove, and the detection surface 431 is the tool installation surface. When inspecting the turret, the flatness of the detection surface 431 is an indispensable part of the turret inspection;

[0039] It should be noted that the flatness of the tool installation groove determines the flatness of the tool after installation, and the flatness of the detection surface 431 represents the flatness of the tool installation groove. If the detection surface 431 is tilted or uneven, the tool after installation will also be tilted, thereby affecting the processing accuracy. Therefore, the flatness of the detection surface 431 determines the processing accuracy of the workpiece;

[0040] In order to facilitate the detection of the detection member 4 on the installation platform 2, as shown in FIG. Figure 2 , Figure 4 As shown, a detection assembly 5 is fixedly installed on the installation platform 2, and the detection assembly 5 includes a driving cylinder 51 fixedly installed on one side of the tower body 41. At the same time, a slide rail 52 is also fixedly installed on the installation platform 2, and a slider 53 is slidably installed on the slide rail 52. The output end of the driving cylinder 51 is fixedly connected to the slider 53. When the driving cylinder 51 is started, the slider 53 can be pushed to slide toward the position of the tower body 41;

[0041] A connecting seat 54 is fixedly installed on the top of the slider 53 by bolts, a gauge seat 56 is fixedly installed on one side of the connecting seat 54, a bracket 57 is fixedly installed on one side of the gauge seat 56, a micrometer 58 is fixedly installed on the side of the bracket 57 away from the gauge seat 56, and a contact end (not shown in the figure) is provided at the bottom of the micrometer 58, and the contact end is used to contact the detection surface 431. When the surface inclination angle of the detection surface 431 is large, the contact end feeds back the contact result to the micrometer 58, and the staff can observe the flatness of the detection surface 431 through the pointer on the micrometer 58;

[0042] When inspecting the turret, the staff starts the driving cylinder 51, and the output end of the driving cylinder 51 drives the slider 53 to slide, and the sliding of the slider 53 drives the connecting seat 54 to move, and the movement of the connecting seat 54 drives the meter seat 56 and the bracket 57 to move, and synchronously drives the micrometer 58 to move, and the contact end of the micrometer 58 moves on the detection surface 431. At this time, the staff can clearly know the flatness of the detection surface 431 through the pointer on the micrometer 58. Further, in order to facilitate the detection operation, the staff can install a camera (not shown in the figure) on one side of the installation platform 2. The camera is mainly used to shoot and record the micrometer 58 and the detection surface 431 area. When the pointer of the micrometer 58 moves too much, the camera marks the video. In this way, the staff does not need to stare at the micrometer 58 all the time. After the detection operation is completed, the staff can know the turret detection result through the video.

[0043] It should be noted that, since there are multiple tool installation slots on the same group of turrets, and each group of tool installation slots needs to continuously install and remove different tools, when the tool installation slots are installed with different tools for processing, their detection surfaces 431 may have angle deviations, so it is necessary to perform cyclic fatigue testing on the detection surfaces 431 of each group of tool installation slots. When the staff starts the driving cylinder 51 to drive the micrometer 58 to move, after completing the detection of one group of detection surfaces 431, the staff first controls the output end of the driving cylinder 51 to retract, driving the micrometer 58 back to the initial position, and then starts the driving motor 42. The driving motor 42 starts to drive the turret base 43 to rotate, rotating the next group of tool installation slots to the specified detection position, and then the staff starts the driving cylinder 51 again to detect the next group of detection surfaces 431. In this cycle, the detection surfaces 431 of each tool installation slot on the turret can be detected. In this embodiment, a PLC control system is provided in the base 1 to facilitate the alternating opening or closing of each electrical component.

[0044] In the above test, the micrometer 58 is driven to move by the driving cylinder 51, and the tower base 43 is driven to rotate by the driving motor 42, so as to perform a flatness test on the detection surface 431 of each group. At the same time, the detection process and results are recorded by the camera, and the staff does not need to operate alone, thereby improving the detection efficiency of the turret;

[0045] Furthermore, in order to facilitate the testing of the turret of the inclined rail, Figure 3 As shown, a rack 22 is fixedly installed on one side of the support plate 21, and a servo motor 3 is fixedly installed on one side of the base 1. The output end of the servo motor 3 passes through the base 1 and is fixedly installed with a gear 31. The gear 31 is meshed with the rack 22. When the servo motor 3 is started, the gear 31 rotates and synchronously drives the rack 22 to rotate. In this way, the angle of the mounting platform 2 fixedly installed on the support plate 21 can be adjusted, and during the angle adjustment process, the output end of the hydraulic rod 6 extends or contracts according to the angle adjustment to support the mounting platform 2, and after the angle adjustment, it is ensured that the mounting platform 2 is fixed at a specified angle and no longer deflects;

[0046] Since the gear 31 and the rack 22 have high precision, the mounting platform 2 can be easily adjusted to any specified angle. Secondly, since the detection part 4 and the mounting platform 2 have a large weight, and the gear 31 and the rack 22 have good bearing capacity, the detection part 4 and the mounting platform 2 can be stably supported while the angle adjustment can be conveniently performed. At the same time, the transmission speed of the gear 31 and the rack 22 is fast. When the angle adjustment is required, the gear 31 rotates to drive the rack 22 to rotate, thereby speeding up the efficiency of the turret detection.

[0047] To sum up, before inspecting the turret, the servo motor 3 can be started to drive the gear 31 to rotate, and the gear 31 can then drive the rack 22 to rotate, so that the angle of the mounting platform 2 can be adjusted. After the angle adjustment is completed, the drive motor 42 and the drive cylinder 51 are started in sequence to perform fatigue detection on each detection surface 431 on the tower base 43, and the detection process and results are recorded by a camera, thereby improving the inspection efficiency of the turret. While adjusting the angle of the mounting platform 2, since the detection component 5 is installed on the mounting platform 2, when the mounting platform 2 is deflected, it will not affect the detection component 5 from detecting the detection surface 431.

[0048] Embodiment 2: In the above detection method, the contact end of the micrometer 58 is always in contact with the detection surface 431 for detection. When there is local unevenness on the detection surface 431, the contact end can easily slide directly over it, ignoring the local unevenness on the detection surface 431.

[0049] In order to solve this problem, this embodiment makes partial improvements to the structure of the detection component 5, specifically: Figure 4-Figure 7 As shown, first, in the first embodiment, the slider 53 and the connecting seat 54 are fixedly connected by bolts. In this embodiment, a slot is provided on the slider 53, and a latch 511 is placed in the slot. The top of the latch 511 is fixedly connected to the bottom of the connecting seat 54. In the initial state, due to the action of gravity, the connecting seat 54 is close to the slider 53. When the connecting seat 54 is subjected to an upward force, the connecting seat 54 and the slider 53 are separated, but the latch 511 is still inserted in the slot. In this way, when the slider 53 moves, it will always drive the connecting seat 54 to move synchronously, and will not affect the detection of the detection surface 431 by the micrometer 58;

[0050] A limit block 9 is fixedly installed on the top of the connecting seat 54, and a fixing plate 55 is fixedly installed on the mounting platform 2 by fasteners. The fixing plate 55 is located above the connecting seat 54, and a limit slot 8 is provided in the fixing plate 55. The limit block 9 is slidably connected with the limit slot 8. When the connecting seat 54 moves driven by the slider 53, the limit block 9 slides in the limit slot 8.

[0051] like Fig. 9 As shown, a first channel 81 is provided in the limiting groove 8, and the first channel 81 is a horizontal channel. At the same time, a limiting pin 91 is fixedly installed on one side of the limiting block 9 close to the first channel 81, and one end of the limiting pin 91 abuts in the first channel 81 to form an abutting end 92. In the embodiment, one end of the abutting end 92 close to the first channel 81 is made of a flexible material, which has a certain elasticity. In the initial state, the abutting end 92 abuts in the first channel 81 and is already in an extruded state. For the convenience of description, the position of the abutting end 92 is defined as the initial position.

[0052] A second channel 82 is provided on one side of the first channel 81 away from the abutting end 92. The second channel 82 is a downwardly inclined channel. A third channel 83 is provided at the end of the second channel 82. The third channel 83 is an upwardly inclined channel. The second channel 82 and the third channel 83 form a V-shaped channel. A first detection point 87 is provided at a position where the second channel 82 and the third channel 83 are connected.

[0053] In this embodiment, in the initial state, the connection seat 54 is at a certain distance from the slider 53, the latch pin 511 protrudes less from the slot, and the contact end of the micrometer 58 is at a higher level than the detection surface 431 to be detected. In order to enable the connection seat 54 to maintain this state before the detection begins, the limit pin 91, the limit block 9 and a part of the abutting end 92 are all made of a material with a relatively high hardness so that they can support the connection seat 54, the gauge seat 56, the bracket 57 and the micrometer 58. When the connection seat 54 moves driven by the slider 53, the limit block 9 slides in the limit slot 8, and the abutting end 92 slides in the first channel 81. When the abutting end 92 slides in the first channel 81, since the level of the abutting end 92 is higher than the level of the detection surface 431 to be detected, the micrometer 58 has not yet detected the detection surface 431.

[0054] As the slider 53 continues to move, the abutting end 92 enters the second channel 82 from the first channel 81. Since the second channel 82 is an inclined channel, when the abutting end 92 slides in the second channel 82, the limit block 9 also slides downwardly until it reaches the first detection point 87. During this process, the connecting seat 54 slides downward to approach the slider 53, the latch 511 slides downward, and the micrometer 58 slides downward at the same time. When the abutting end 92 reaches the first detection point 87, the contact end of the micrometer 58 is attached to and abuts against the detection surface 431. At this time, the micrometer 58 detects the detection surface 431.

[0055] Then the slider 53 continues to move, and the abutting end 92 leaves the first detection point 87 and enters the third channel 83, and continues to slide in the third channel 83. Since the third channel 83 is a section of an upwardly inclined channel, when the abutting end 92 slides in the third channel 83, the connecting seat 54 moves upward and separates from the slider 53, and at the same time, the micrometer 58 moves upward and separates from the detection surface 431, and no longer detects the detection surface 431.

[0056] Continue to refer Fig. 9 At the end of the third channel 83, a first extension section 89 is provided. The first extension section 89 is a horizontal channel. At the end of the first extension section 89, a V-shaped channel similar to the second channel 82 and the third channel 83 is also provided. A detection point is also provided at the bottom of the channel.

[0057] It can be understood that when the abutting end 92 slides in the first channel 81, the position height of the micrometer 58 is higher than the position height of the detection surface 431. At this time, the micrometer 58 will not detect the detection surface 431. When the abutting end 92 passes through the second channel 82 and reaches the first detection point 87, the contact end of the micrometer 58 will contact the detection surface 431 and perform a touch detection on the detection surface 431. Then, the abutting end 92 passes through the third channel 83 and enters the first extension section 89. When the abutting end 92 passes through the first extension section 89 and reaches the detection point, the micrometer 58 will detect the detection surface 431. In this way, multiple groups of V-shaped channels can be provided in the limiting groove 8. When the abutting end 92 passes through the V-shaped channel, the micrometer 58 will perform a touch detection on the detection surface 431.

[0058] In this embodiment, specific reference is made to Fig. 9 A V-shaped channel is provided at the end of the first extension section 89, and a second extension section 810 is provided at the end of the V-shaped channel. Meanwhile, a third extension section 811 is provided on the side of the second extension section 810 away from the first extension section 89. A V-shaped channel is provided between each group of extension sections. There are three groups of V-shaped channels in total, that is, the micrometer 58 performs three point touch detections on the detection surface 431 during the movement. After the point touch detection, the average value is obtained to determine the flatness of the detection surface 431. In addition, the point touch detection method can be used to focus on the detection of a part of the detection surface 431, so as to detect the local roughness in the tool installation groove. Uneven position, improve the detection accuracy, it should be noted that the staff can replace the limit groove 8 according to the shape of the tool and the detection requirements. In this embodiment, the first channel 81 and its extension end can be understood as the detection surface 431, and the position of each group of detection points, that is, the micrometer 58 detects the detection surface 431. The staff can adjust the number and position of the detection points according to the needs to meet the detection of different types of turrets. When replacing, the staff only needs to remove the fixing plate 55 from the mounting platform 2, and then install the fixing plate 55 with the specified limit groove 8. The specific installation and disassembly method will not be elaborated here.

[0059] A fourth channel 84 is provided at the end of the first channel 81, and the fourth channel 84 is a channel inclined downward. A fifth channel 85 is provided at the end of the fourth channel 84, and the fifth channel 85 is a horizontal channel. A sixth channel 86 is provided at the end of the fifth channel 85, and the sixth channel 86 is a channel inclined upward. The end of the sixth channel 86 communicates with the first channel 81.

[0060] Depend on Fig. 9It can be known that the first detection point 87 and the remaining detection points are all set in the fifth channel 85, and a transition slope 88 is set on one side of each group of detection points. The highest position of the transition slope 88 is higher than the groove bottom height of the fifth channel 85 and forms a transition step, so that when the abutting end 92 reaches the detection point, it will not directly enter the fifth channel 85, but will rise again along the rising end of the V-shaped channel and return to the extended end of the first channel 81. Secondly, a blocking slope is set at the end of the sixth channel 86. The highest position of the blocking slope is higher than the groove bottom height of the sixth channel 86 and forms a blocking step, so that when the abutting end 92 slides in the first channel 81, it will not directly enter the sixth channel 86;

[0061] After the limit block 9 is displaced under the drive of the driving cylinder 51, the abutting end 92 finally reaches the end position of the third extension section 811. At this time, the dial gauge 58 slides over the detection surface 431 close to the axis of the tower base 43, and then the output end of the driving cylinder 51 retracts and drives the limit block 9 to retreat. The retreat of the limit block 9 drives the abutting end 92 to move. The abutting end 92 enters the fourth channel 84 from the end position of the extension end of the first channel 81, enters the fifth channel 85 through the fourth channel 84, slides through the fifth channel 85 into the sixth channel 86, and finally returns to the initial position of the first channel 81 through the sixth channel 86.

[0062] In this process, since the fourth channel 84 is a channel inclined downward, when the abutting end 92 slides in the channel, the micrometer 58 continuously moves downward, and the horizontal height of its contact end is close to the horizontal height of the detection surface 431. When the abutting end 92 slides in the fifth channel 85, the contact end of the micrometer 58 contacts the detection surface 431, and the detection surface 431 is subjected to sliding detection. When the abutting end 92 slides in the sixth channel 86, the micrometer 58 moves upward. Finally, the micrometer 58 is driven by the abutting end 92 to return to the initial position and the initial horizontal height, so as to facilitate the next group of detection.

[0063] In summary, the present embodiment mainly makes partial improvements to the detection component 5, and divides the detection process into a first section and a second section based on the movement process of the driving cylinder 51. In the first section, the micrometer 58 performs point-touch detection on the detection surface 431, and can focus on the detection of local areas of the tool mounting groove, thereby improving the detection accuracy. In the second section, the sliding detection in the first embodiment can be used to understand the overall flatness of the detection surface 431, and the staff can replace different fixed plates 55 according to needs to adjust the movement trajectory of the limit block 9, thereby adjusting the movement trajectory of the micrometer 58 to meet the detection of different types of turrets.

[0064] Embodiment 3: In the above embodiment, the movement trajectory of the micrometer 58 is changed by the cooperation of the limit groove 8 and the limit block 9, thereby improving the detection method. However, after long-term use, the contact end of the micrometer 58 may be fatigued, thereby affecting the detection accuracy. Therefore, the micrometer 58 needs to be recalibrated. However, when the micrometer 58 is calibrated, the detection needs to be interrupted to cooperate with the calibration operation.

[0065] To solve this problem, Figure 5-Figure 8 As shown, first, in the above embodiment, the meter base 56 and the connecting base 54 are fixedly installed. In this embodiment, the meter base 56 and the connecting base 54 are slidably connected. It should be noted that when the meter base 56 is subjected to an upward or downward force, the meter base 56 is suitable for sliding up and down on the connecting base 54. At the same time, two groups of first lead screws 59 are fixedly installed on one side of the slider 53. The first lead screw 59 includes a bottom plate fixedly installed on one side of the slider 53 and a screw connected to the bottom plate through a bearing. A threaded block is also threadedly connected on the surface of the screw. A driving device is fixedly installed at one end of the screw. The driving device is mainly used The screw rod is used to drive the rotation of the screw rod, and one end of the driving device is fixedly connected to the bottom plate to ensure its stability. A lifting block 510 is fixedly installed on the threaded block, and the top of the lifting block 510 is fixedly connected to the bottom of the meter base 56. When the driving device is started, the screw rod rotates to drive the threaded block to move, thereby driving the lifting block 510 to move. When the lifting block 510 slides up and down driven by the first lead screw 59, it will drive the meter base 56 to slide up and down synchronously, thereby facilitating the adjustment of the horizontal height of the micrometer 58. It should be noted that the first lead screw 59 is a precision lead screw, which can accurately adjust the moving distance of the lifting block 510.

[0066] A second lead screw 7 is fixedly mounted on one side of the mounting platform 2, a connecting rod 71 is fixedly mounted on one side of the second lead screw 7, a check block 72 is fixedly mounted on one end of the connecting rod 71 away from the second lead screw 7, in order to facilitate the check of the micrometer 58, a boss 73 is provided on the top of the check block 72, the surface of the boss 73 protrudes from the top of the check block 72, the horizontal height of the top of the boss 73 is on the same horizontal plane as the horizontal height of the detection surface 431, when the contact end of the micrometer 58 reaches the position of the boss 73, the contact end of the micrometer 58 contacts the boss 73, after the contact, the pointer of the micrometer 58 will rotate, if it rotates to within the specified range, it means that the micrometer 58 is normal, otherwise the micrometer 58 is fatigued or damaged, the boss 73 is provided so that the contact end of the micrometer 58 can check the micrometer 58 before reaching the detection surface 431;

[0067] After multiple tests, the contact end of the micrometer 58 may be fatigued, so the micrometer 58 needs to be recalibrated. At the beginning of each set of tests, the contact end of the micrometer 58 is driven by the driving cylinder 51 to approach the position of the calibration block 72. In this embodiment, the starting position of the micrometer 58 needs to be redefined. When the abutting end 92 reaches the first detection point 87, the contact end of the micrometer 58 is in contact with the boss 73. Since the highest position of the boss 73 is higher than the top position of the calibration block 72, the pointer of the micrometer 58 rotates after the contact, thereby simulating the micrometer 58 detecting the detection surface 431. In the subsequent process, when the abutting end 92 reaches the detection point through the first extension section 89, the contact end of the micrometer 58 is in contact with the detection surface 431.

[0068] If the pointer rotation range of the micrometer 58 exceeds the specified range or does not reach the specified range after contacting the boss 73, it means that the micrometer 58 is fatigued, and the process is recorded by a camera. After knowing that the micrometer 58 is fatigued, the staff can start the first screw 59 through the PLC control system. The first screw 59 starts to drive the lifting block 510 to move upward or downward. The movement of the lifting block 510 drives the meter base 56 to slide up and down on the side of the connecting base 54, and the movement of the meter base 56 drives the micrometer 58 to move synchronously. Since the first screw 59 is an existing precision screw, it can strictly control the moving distance of the lifting block 510, thereby precisely controlling the moving distance of the micrometer 58, so as to calibrate the micrometer 58;

[0069] In the second embodiment, when the abutting end 92 reaches the first detection point 87 or the other detection points, the contact end of the micrometer 58 has already contacted with the detection surface 431 to start detection, while in the present embodiment, when the abutting end 92 reaches the first detection point 87, the contact end of the micrometer 58 contacts the boss 73, and the micrometer 58 is calibrated first, and when the contact end of the micrometer 58 contacts the other detection points, the contact end of the micrometer 58 contacts the detection surface 431 to detect the detection surface 431;

[0070] In summary, in this embodiment, the micrometer 58 can be calibrated before the detection begins through the calibration block 72, and the horizontal height of the dial base 56 can be adjusted through the first lead screw 59 and the lifting block 510, so as to facilitate the adjustment of the horizontal height of the micrometer 58, and complete the calibration and adjustment of the micrometer 58;

[0071] It should be noted that, in the present embodiment, the second lead screw 7 is also an existing precision lead screw, and the structure and working principle of the second lead screw 7 are the same as those of the first lead screw 59. For details, reference may be made to the working principle of the first lead screw 59 mentioned above. When the driving device of the second lead screw 7 is started, it is suitable for driving the connecting rod 71 to move up and down, so as to facilitate the adjustment of the horizontal height of the calibration block 72. When the turret test is performed, it is not necessary to calibrate the micrometer 58 before each test. Therefore, in the initial state, the connecting rod 71 can be controlled to descend by the second lead screw 7, and the calibration block 72 can be driven to move downward synchronously. When the micrometer 58 moves synchronously driven by the driving cylinder 51, it will not contact the calibration block 72, and the test can be started directly.

[0072] After a certain number of tests, the staff will start the second lead screw 7 again, drive the connecting rod 71 to move upward, and the check block 72 will move up to the specified position. At the beginning of the next test, the contact end of the micrometer 58 will first contact the boss 73 to calibrate the micrometer 58. The start of the second lead screw 7 can be selectively started according to the number of starts of the driving cylinder 51. This process can be pre-programmed and then realized through the PLC control system. After a specified number of tests, the second lead screw 7 will start to drive the check block 72 to move upward to calibrate the micrometer 58.

[0073] Since the micrometer 58 is a periodic inspection, during the inspection process, if the micrometer 58 detects that the inspection surface 431 is tilted, the second screw 7 will start and drive the verification block 72 to move upward. The micrometer 58 will contact the verification block 72 during the retraction process. If the micrometer 58 passes the inspection, it means that the inspection surface 431 is indeed uneven. If the micrometer 58 fails, the first screw 59 will start and drive the lifting block 510 to move up or down to adjust the horizontal height of the micrometer 58. This shows that the micrometer 58 is unqualified and the inspection surface 431 is flat. Subsequently, during the next inspection, if the micrometer 58 also detects that the inspection surface 431 is uneven after verification, staff intervention is required to re-inspect the micrometer 58 and the inspection surface 431. When this happens, the micrometer 58 may be damaged and cannot continue to be inspected through verification, or the inspection surface 431 may be unqualified.

[0074] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
