Description

Technical Field

[0001] The present application relates to the technical field of taper detection, and in particular to a testing tool for conveniently testing the taper of shaft parts. Background Art

[0002] A gauge is a specialized inspection tool designed based on product characteristics and testing requirements. It's used to quickly determine a part's quality status, including its size, shape, and position. It's widely used for quality control on production sites and can replace specialized measuring tools for efficient testing. Examples of gauges include smooth plug gauges, thread plug gauges, calipers, and outside diameter ring gauges.

[0003] Related technology discloses a shaft workpiece, referring to Figure 1 , including a shaft seat 01 and a shaft body 02. The shaft body 02 is integrally formed on the shaft seat 01. A first conical surface 03 and a second conical surface 04 are processed on the outer wall of the shaft body 02 along its axial direction.

[0004] The above products are usually processed by machine tools, and shaft workpieces are usually made of steel. Therefore, during the processing of the machine tool, the turning tool will be worn, which will cause the diameter of the conical surface of the shaft to be too large when the machine tool processes the conical surface on the shaft. Therefore, it is necessary to measure, adjust and compensate the cutting amount of the turning tool.

[0005] However, since the conical surface of the shaft is inclined, it is difficult for common measuring tools to quickly and accurately measure the diameter of the conical surface. As a result, in the process of compensating the cutting depth of the turning tool, the diameter of the conical surface of the shaft is easily over-cut, thereby causing the workpiece to be scrapped, which is a shortcoming. Summary of the Invention

[0006] In order to improve the difficulty in measuring the taper of a shaft, the present application provides a testing fixture that is convenient for testing the taper of shaft parts.

[0009] By adopting the above technical solution, the worker first places the workpiece to be measured on the base plate, and then fixes and positions the workpiece by the positioning clamping member so that the axis of the workpiece coincides with the axis of the base plate. Then the lifting member drives the lifting plate to descend and gradually approaches the top of the workpiece until the abutment plate abuts the top of the workpiece. Finally, the detection component on the abutment plate directly measures the taper index of the workpiece, which is convenient for the worker to adjust the amount of cutting of the compensating turning tool later, thereby reducing the possibility of over-turning of the workpiece. After the abutment plate abuts against the top of the workpiece, the measuring member first drives the second measuring rod to descend so that the second ring gauge can It can be put on the second conical surface of the workpiece, and then the first measuring rod is driven to descend so that the first ring gauge can be put on the first conical surface of the workpiece. At this time, the worker reads the distance between the abutment disk and the second ring gauge, and the abutment disk and the first ring gauge through the marked arrow, and then compares it with the distance value of the design standard. When the read distance value is greater than the standard distance value, it indicates that the workpiece has been over-turned and is scrap. When the read distance value is less than the standard distance value, it indicates that the conical surface diameter of the workpiece is too large. Then the worker compensates the cutting amount of the turning tool on the machine tool according to the read distance value, so as to facilitate precise processing of the workpiece.

[0015] By adopting the above technical solution, the control system starts the second cylinder, the piston rod of the second cylinder extends, and the piston rod of the second cylinder drives the second mounting plate to descend through the support plate, and the second mounting plate drives the second ring gauge to descend synchronously through the second measuring rod until the second ring gauge is sleeved on the second conical surface of the workpiece. At this time, the piston rod of the second cylinder will drive the support plate to continue to descend until the support plate is separated from the second mounting plate, and then the control system starts the first cylinder, so that the first ring gauge is sleeved on the first conical surface of the workpiece, and at the same time the support plate is separated from the first mounting plate, which is beneficial to improve the measurement accuracy of the conical surface of the workpiece.

[0016] Optionally, the detection assembly includes a first sliding plate and a second sliding plate slidably mounted on the guide column, the second sliding plate is located between the first sliding plate and the abutment plate, the lifting plate is provided with a third cylinder and a fourth cylinder electrically connected to the control system, the first sliding plate is provided on the piston rod of the third cylinder, the second sliding plate is provided on the piston rod of the fourth cylinder, and the first sliding plate and the second sliding plate are both provided with a cone measuring part for measuring the taper of the workpiece.

[0017] By adopting the above technical solution, the worker first installs the standard workpiece on the base plate. When the abutment plate is pressed against the top of the workpiece, the control system starts the fourth cylinder, the piston rod of the fourth cylinder extends, and the piston rod of the fourth cylinder drives the second slide plate to descend. At this time, the measuring cone on the second slide plate measures the second conical surface on the workpiece, and then the control system starts the third cylinder to make the measuring cone on the first slide plate measure the first conical surface on the workpiece, thereby completing the initial adjustment. After that, it is only necessary to place the workpiece to be measured on the base plate.

[0018] Optionally, the measuring cone member includes an adjusting block slidably arranged on the abutment disk, the adjusting block slides along the radial direction of the abutment disk axis, the abutment disk is provided with an adjusting slot for the adjusting block to slide, the abutment disk is bolted with a locking plate, an adjusting screw is rotatably arranged on the locking plate, the adjusting block is threadedly connected to the adjusting screw, the adjusting screw is threadedly connected with a locking nut, the locking nut is used to abut the locking plate, a measuring cone rod is vertically slidably arranged on the adjusting block, and A second scale is provided on the measuring cone rod and along the axial direction of the guide column. A bottom mounting plate is provided at the bottom of the measuring cone rod, and a measuring cone block is arranged on the bottom mounting plate. The measuring cone block is used to abut the first conical surface or the second conical surface on the workpiece. An anti-slip plate is provided on the top of the measuring cone rod. The first sliding plate and the second sliding plate are both provided with an avoidance groove for the sliding of the measuring cone rod. An end block is provided with a sliding sleeve on the measuring cone rod. The end block slides along the length direction of the avoidance groove, and the anti-slip plate is used to abut the top of the end block.

[0019] By adopting the above technical solution, after the standard workpiece is fixed on the base plate, the worker rotates the adjusting screw, and the rotating adjusting screw pushes the adjusting block to slide, and the adjusting block drives the measuring cone rod to slide synchronously, and the measuring cone rod drives the measuring cone block to slide synchronously, so that the measuring cone block can abut against the second conical surface on the standard workpiece. At this time, the worker tightens the locking nut, and then the second sliding plate drops a certain distance. Under the action of the anti-slip plate, the measuring cone rod drives the measuring cone block to abut against the second conical surface on the standard workpiece. At the same time, the reading between the top of the standard workpiece and the measuring cone block is recorded at this time. In the same way, the measuring cone block corresponding to the first sliding plate is recorded. The value on the first conical surface of the standard workpiece is used to complete the initial measurement of the standard workpiece. Then the control system starts the lifting cylinder, and the piston rod of the lifting cylinder drives the lifting plate to rise. At this time, the measuring cone block will be separated from the standard workpiece. After that, the workpiece to be tested is placed on the base plate in turn. As the measuring cone block at the bottom of the measuring cone rod abuts against the conical surface on the workpiece, the worker reads the reading between the top of the workpiece and the measuring cone block at this time, and then compares the read value with the corresponding value of the standard workpiece, so as to quickly and accurately measure the taper of the workpiece, and can measure the taper on shaft workpieces of different sizes.

[0021] By adopting the above technical solution, when the measuring cone rod descends, the measuring cone rod drives the measuring cone block on the bottom plate to descend synchronously, and the descending measuring cone block will gradually abut against the conical surface of the workpiece until the measuring cone block fits the inclination direction of the conical surface on the workpiece. During this process, the measuring cone block will continue to rotate, and the rotating measuring cone block will abut the measuring end of the dial indicator, and the index of the dial indicator will change to adapt to workpieces with different conical surface inclination angles. At the same time, workers can quickly judge whether the workpiece to be measured is qualified by the index of the dial indicator. At the same time, the misreading of the second scale is reduced, which is conducive to improving the accuracy of the taper measurement results of the workpiece.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The worker first places the workpiece to be measured on the base plate. The workpiece is then fixed and positioned using the positioning clamps so that the axis of the workpiece coincides with the axis of the base plate. The lifting member then drives the lifting plate down and gradually approaches the top of the workpiece until the abutment plate abuts the top of the workpiece. Finally, the detection component on the abutment plate directly measures the taper index of the workpiece, which facilitates the worker's subsequent adjustment to compensate for the cutting depth of the turning tool, thereby reducing the possibility of over-cutting the workpiece.

[0024] 2. After the abutment disc is pressed against the top of the workpiece, the measuring part first drives the second measuring rod down so that the second ring gauge can be put on the second conical surface of the workpiece, and then drives the first measuring rod down so that the first ring gauge can be put on the first conical surface of the workpiece. At this time, the worker reads the distance between the abutment disc and the second ring gauge, and between the abutment disc and the first ring gauge through the marked arrows, and then compares them with the distance value of the design standard. When the read distance value is greater than the standard distance value, it indicates that the workpiece has been over-turned and is scrapped. When the read distance value is less than the standard distance value, it indicates that the conical surface diameter of the workpiece is too large. Then the worker compensates the cutting amount of the turning tool on the machine tool according to the read distance value, which facilitates precise processing of the workpiece.

[0025] 3. The worker rotates the adjusting screw, and the rotating adjusting screw pushes the adjusting block to slide. The adjusting block drives the measuring cone rod to slide synchronously, and the measuring cone rod drives the measuring cone block to slide synchronously, so that the measuring cone block can abut the second cone surface on the standard workpiece. At this time, the worker tightens the locking nut, and then the second slide plate drops a distance. Under the action of the anti-slip plate, the measuring cone rod drives the measuring cone block to abut the second cone surface on the standard workpiece. At the same time, the reading between the top of the standard workpiece and the measuring cone block is recorded. In the same way, the reading of the measuring cone block corresponding to the first slide plate on the first cone surface of the standard workpiece is recorded. The value is used to complete the initial measurement of the standard workpiece, and then the control system starts the lifting cylinder. The piston rod of the lifting cylinder drives the lifting plate to rise. At this time, the measuring cone block will be separated from the standard workpiece. After that, the workpiece to be tested is placed on the base plate in turn. As the measuring cone block at the bottom of the measuring cone rod abuts against the conical surface on the workpiece, the worker reads the reading between the top of the workpiece and the measuring cone block at this time, and then compares the read value with the corresponding value of the standard workpiece, so as to quickly and accurately measure the taper of the workpiece, and can measure the taper on shaft workpieces of different sizes.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 2-Figure 6 This application is described in further detail.

[0034] The embodiment of the present application discloses a checking fixture for conveniently checking the taper of shaft parts. Example

[0035] Reference Figure 2 A convenient inspection tool for testing the taper of shaft parts includes a base plate 1, a stand 2 is welded on the base plate 1, and a workpiece 0 is placed on the base plate 1.

[0036] Reference Figure 2 and Figure 3 A positioning clamp 3 is arranged on the base plate 1. The positioning clamp 3 is used to make the axis of the workpiece 0 coincide with the axis of the base plate 1. The positioning clamp 3 includes a plurality of clamping blocks 31 slidably arranged on the base plate 1. The plurality of clamping blocks 31 are evenly distributed circumferentially along the axis of the base plate 1. The clamping blocks 31 slide in the radial direction of the axis of the base plate 1. A plurality of sliding grooves 32 for the clamping blocks 31 to slide are provided on both vertical sides of the base plate 1.

[0037] Reference Figure 2 and Figure 3The clamping block 31 corresponds to the slide groove 32 one by one. The slide groove 32 of the base plate 1 is bolted with a slot rod 11. The clamping block 31 is slidably sleeved on the slot rod 11. The bottom of the base plate 1 is coaxially connected to the driving plate 33. The circumferential edge of the driving plate 33 is hinged with a connecting rod 34 between each clamping block 31. The bottom of the base plate 1 is bolted with a clamping motor 35 electrically connected to the control system, and the driving plate 33 is coaxially bolted to the output shaft of the clamping motor 35.

[0038] Reference Figure 2 A lifting plate 4 coaxial with the base plate 1 is arranged on the vertical frame 2 for vertical sliding. A lifting component 5 for driving the lifting plate 4 to slide vertically is arranged on the vertical frame 2. The lifting component 5 includes connecting plates 51 welded on both sides of the lifting plate 4. Two lifting cylinders 52 electrically connected to the control system are bolted to the vertical frame 2. The lifting cylinders 52 correspond to the connecting plates 51 one by one, and the connecting plates 51 are bolted to the piston rods of the lifting cylinders 52.

[0039] Reference Figure 2 and Figure 3 A guide column 6 is coaxially welded to the bottom of the lifting plate 4, and an abutment plate 7 is coaxially welded to the end of the guide column 6 facing away from the lifting plate 4. The abutment plate 7 is used to abut the top of the workpiece 0, and a detection component for detecting the taper of the workpiece 0 is arranged on the abutment plate 7.

[0040] The worker first places the workpiece 0 on the base plate 1. Then, the control system starts the clamping motor 35. The output shaft of the clamping motor 35 drives the driving disk 33 to rotate forward. The rotating driving disk 33 drives multiple clamping blocks 31 synchronously and close to each other through the connecting rod 34. The multiple sliding clamping blocks 31 will push the workpiece 0 to slide toward the axis of the base plate 1 until the workpiece 0 stops moving. At this time, the workpiece 0 is clamped and fixed at the axis of the base plate 1.

[0041] Reference Figure 2 and Figure 3 The detection assembly includes a first measuring rod 81 and a second measuring rod 82 arranged vertically for sliding on the abutment plate 7. The first measuring rod 81 is bolted with a first ring gauge 83 coaxial with the guide column 6. Two first measuring rods 81 are circumferentially arranged on the first ring gauge 83. The first ring gauge 83 is used to be sleeved on the first conical surface 03 of the workpiece 0. The second measuring rod 82 is bolted with a second ring gauge 84 coaxial with the guide column 6.

[0042] Reference Figure 2 、 Figure 3 and Figure 4Two second measuring rods 82 are arranged circumferentially on the second ring gauge 84. The second ring gauge 84 is used to be sleeved on the second conical surface 04 of the workpiece 0. A first scale 85 is provided on the first measuring rod 81 and the second measuring rod 82 along the axial direction of the guide column 6. A marking arrow 86 for indicating the first scale 85 is bolted to the abutment disk 7. The marking arrow 86 points to the intersection of the lower surface of the abutment disk 7 and the first scale 85.

[0043] Reference Figure 2 and Figure 3 A measuring piece 87 is arranged on the lifting plate 4 to drive the first ring gauge 83 and the second ring gauge 84 to be sleeved on the workpiece 0. The measuring piece 87 includes a first mounting plate 871 and a second mounting plate 872 slidably sleeved on the guide column 6. The second mounting plate 872 is located between the first mounting plate 871 and the abutment plate 7. The end of the first measuring rod 81 facing away from the first ring gauge 83 is bolted to the first mounting plate 871. The lifting plate 4 is bolted with a first cylinder 873 and a second cylinder 874.

[0044] Reference Figure 2 and Figure 3 The first cylinder 873 and the second cylinder 874 are both electrically connected to the control system, and the piston rods of the first cylinder 873 and the second cylinder 874 are both bolted with a support plate 875. The support plate 875 on the piston rod of the first cylinder 873 is used to abut the bottom of the first mounting plate 871, and the end of the second measuring rod 82 facing away from the second ring gauge 84 is bolted to the second mounting plate 872, and the support plate 875 on the piston rod of the second cylinder 874 is used to abut the bottom of the second mounting plate 872.

[0045] When the workpiece 0 is clamped and fixed by the clamping block 31, the control system starts the lifting cylinder 52, the piston rod of the lifting cylinder 52 contracts, and the piston rod of the lifting cylinder 52 drives the lifting plate 4 to descend through the connecting plate 51. The lifting plate 4 drives the abutment plate 7 to descend synchronously through the guide column 6 until the abutment plate 7 is tightly pressed against the top of the workpiece 0, thereby completing the fixation of the workpiece 0 in the vertical direction.

[0046] Then the control system starts the second cylinder 874, the piston rod of the second cylinder 874 extends, and the piston rod of the second cylinder 874 drives the support plate 875 to descend, and the second mounting plate 872 descends synchronously under the action of gravity. The second mounting plate 872 drives the second ring gauge 84 to descend synchronously through the second measuring rod 82 until the second ring gauge 84 is mounted on the second conical surface 04 of the workpiece 0. At this time, the piston rod of the second cylinder 874 will drive the support plate 875 to continue to descend.

[0047] Until the support plate 875 is separated from the second mounting plate 872, then the control system starts the first cylinder 873, and the piston rod of the first cylinder 873 drives the support plate 875 to descend, and the first mounting plate 871 descends synchronously under the action of gravity, until the first ring gauge 83 is sleeved on the first conical surface 03 of the workpiece 0. As the piston rod of the first cylinder 873 drives the support plate 875 to continue to descend, the support plate 875 is separated from the bottom of the first mounting plate 871.

[0048] The worker reads the distance between the abutment disk 7 and the second ring gauge 84, and between the abutment disk 7 and the first ring gauge 83 through the marked arrow 86, and then compares them with the distance value of the design standard. When the read distance value is greater than the standard distance value, it indicates that the workpiece 0 has been over-turned and is scrap.

[0049] When the read distance value is smaller than the standard distance value, it indicates that the conical surface diameter of the workpiece 0 is insufficiently turned. The worker then adjusts the machine tool to compensate for the cutting amount of the turning tool according to the read distance value, thereby accurately processing the conical surface of the workpiece 0.

[0050] The implementation principle of Example 1 is as follows: the worker first places the workpiece 0 on the base plate 1, and then the control system starts the clamping motor 35. The output shaft of the clamping motor 35 drives the driving disk 33 to rotate forward, and the rotating driving disk 33 drives multiple clamping blocks 31 synchronously and close to each other through the connecting rod 34. The multiple sliding clamping blocks 31 will push the workpiece 0 to slide toward the axis of the base plate 1 until the workpiece 0 stops moving. At this time, the workpiece 0 is clamped and fixed at the axis of the base plate 1.

[0051] When the workpiece 0 is clamped and fixed by the clamping block 31, the control system starts the lifting cylinder 52, the piston rod of the lifting cylinder 52 contracts, and the piston rod of the lifting cylinder 52 drives the lifting plate 4 to descend through the connecting plate 51. The lifting plate 4 drives the abutment plate 7 to descend synchronously through the guide column 6 until the abutment plate 7 is tightly pressed against the top of the workpiece 0, thereby completing the fixation of the workpiece 0 in the vertical direction.

[0052] Then the control system starts the second cylinder 874, the piston rod of the second cylinder 874 extends, and the piston rod of the second cylinder 874 drives the support plate 875 to descend, and the second mounting plate 872 descends synchronously under the action of gravity. The second mounting plate 872 drives the second ring gauge 84 to descend synchronously through the second measuring rod 82 until the second ring gauge 84 is mounted on the second conical surface 04 of the workpiece 0. At this time, the piston rod of the second cylinder 874 will drive the support plate 875 to continue to descend.

[0053] Until the support plate 875 is separated from the second mounting plate 872, then the control system starts the first cylinder 873, and the piston rod of the first cylinder 873 drives the support plate 875 to descend, and the first mounting plate 871 descends synchronously under the action of gravity, until the first ring gauge 83 is sleeved on the first conical surface 03 of the workpiece 0. As the piston rod of the first cylinder 873 drives the support plate 875 to continue to descend, the support plate 875 is separated from the bottom of the first mounting plate 871.

[0054] The worker reads the distance between the abutment disk 7 and the second ring gauge 84, and between the abutment disk 7 and the first ring gauge 83 through the marked arrow 86, and then compares them with the distance value of the design standard. When the read distance value is greater than the standard distance value, it indicates that the workpiece 0 has been over-turned and is scrap.

[0055] When the read distance value is smaller than the standard distance value, it indicates that the conical surface diameter of the workpiece 0 is insufficiently turned. The worker then adjusts the machine tool to compensate for the cutting amount of the turning tool according to the read distance value, thereby accurately processing the conical surface of the workpiece 0.

The measuring cone block 9509 is used to abut the first cone surface 03 or the second cone surface 04 on the workpiece 0. A dial indicator 10 is bolted to the bottom mounting plate 9508. The measuring end of the dial indicator 10 is located on the side of the measuring cone block 9509 facing away from the workpiece 0. An anti-slip plate 9510 is bolted to the top of the measuring cone rod 9506.

[0060] The worker first installs and fixes the standard workpiece 0 on the base plate 1, and after the abutment plate 7 is pressed against the top of the workpiece 0, the worker rotates the adjustment screw 9504 corresponding to the second sliding plate 92. The rotating adjustment screw 9504 pushes the adjustment block 9501 to slide, and the adjustment block 9501 drives the measuring cone rod 9506 to slide synchronously. The measuring cone rod 9506 drives the measuring cone block 9509 to slide synchronously, so that the perpendicular line along the axis direction of the guide column 6 can fall on the second cone surface 04 on the standard workpiece 0.

[0061] Then, the worker tightens the locking nut 9505 to fix the position of the adjustment block 9501. Subsequently, the control system starts the fourth cylinder 94, and the piston rod of the fourth cylinder 94 extends. The piston rod of the fourth cylinder 94 drives the second slide plate 92 to descend. Under the action of the anti-slip plate 9510, the measuring cone rod 9506 on the second slide plate 92 descends synchronously under the action of gravity. At the same time, the measuring cone rod 9506 drives the measuring cone block 9509 and the dial indicator 10 to descend synchronously.

[0062] refer to Figure 5 and Figure 6 The first sliding plate 91 and the second sliding plate 92 are both provided with an avoidance groove 9511 for the sliding of the measuring cone rod 9506. There are two measuring cone rods 9506 on the first sliding plate 91 and the second sliding plate 92 respectively, and the vertical sliding sleeve on the measuring cone rod 9506 is provided with an end block 9512.

[0063] refer to Figure 5 and Figure 6 A guide rail 12 is welded in the avoidance groove 9511 of the first sliding plate 91 and the avoidance groove 9511 of the second sliding plate 92. The length direction of the guide rail 12 is parallel to the axial direction of the adjustment screw 9504. The end block 9512 slides in cooperation with the guide rail 12, and the anti-slip plate 9510 is used to abut the top of the end block 9512.

[0064] Until the rotating measuring cone block 9509 abuts against the second conical surface 04 on the standard workpiece 0. As the second slide 92 continues to descend, the measuring cone block 9509 will gradually rotate and fit the second conical surface 04 on the standard workpiece 0, and the measuring cone rod 9506 will slide relative to the second slide 92.

[0065] During this process, the measuring cone block 9509 will push the measuring end of the dial indicator 10, and the index of the dial indicator 10 will change. The worker will then record the second scale 9507 reading and the dial indicator 10 index at this time. Following the same operation, the first slide 91 will be lowered, and then the second scale 9507 reading and the dial indicator 10 index corresponding to the first cone surface 03 on the standard workpiece 0 will be recorded.

[0066] The control system starts the lifting cylinder 52 to separate the measuring cone block 9509 from the standard workpiece 0, then removes the standard workpiece 0 and places the same workpiece 0 to be measured on the base plate 1. As the control system starts the lifting cylinder 52 again, the abutment plate 7 abuts against the top of the workpiece 0 to be measured. At this time, the dial indicator 10 will directly measure the value corresponding to the cone surface of the workpiece 0 to be measured.

[0067] The worker can intuitively determine whether the workpiece 0 to be measured is qualified by comparing the index of the dial indicator 10 of the workpiece 0 to be measured with the index value of the dial indicator 10 at the corresponding position of the standard workpiece 0. At the same time, if the reading of the second scale 9507 of the workpiece to be measured is less than the reading difference at the corresponding position of the standard workpiece 0, the worker can adjust the cutting depth of the turning tool on the lathe to ensure that the workpiece 0 is accurately processed.

[0068] The implementation principle of Example 2 is as follows: the worker first installs and fixes the standard workpiece 0 on the base plate 1, and after the abutment plate 7 is pressed against the top of the workpiece 0, the worker rotates the adjustment screw 9504 corresponding to the second sliding plate 92, and the rotating adjustment screw 9504 pushes the adjustment block 9501 to slide, and the adjustment block 9501 drives the measuring cone rod 9506 to slide synchronously, and the measuring cone rod 9506 drives the measuring cone block 9509 to slide synchronously, so that the perpendicular line along the axial direction of the guide column 6 can fall on the second cone surface 04 on the standard workpiece 0.

[0069] Then, the worker tightens the locking nut 9505 to fix the position of the adjustment block 9501. Subsequently, the control system starts the fourth cylinder 94, and the piston rod of the fourth cylinder 94 extends. The piston rod of the fourth cylinder 94 drives the second slide plate 92 to descend. Under the action of the anti-slip plate 9510, the measuring cone rod 9506 on the second slide plate 92 descends synchronously under the action of gravity. At the same time, the measuring cone rod 9506 drives the measuring cone block 9509 and the dial indicator 10 to descend synchronously.

[0070] Until the rotating measuring cone block 9509 abuts against the second conical surface 04 on the standard workpiece 0. As the second slide 92 continues to descend, the measuring cone block 9509 will gradually rotate and fit the second conical surface 04 on the standard workpiece 0, and the measuring cone rod 9506 will slide relative to the second slide 92.

[0071] During this process, the measuring cone block 9509 will push the measuring end of the dial indicator 10, and the index of the dial indicator 10 will change. The worker will then record the second scale 9507 reading and the dial indicator 10 index at this time. Following the same operation, the first slide 91 will be lowered, and then the second scale 9507 reading and the dial indicator 10 index corresponding to the first cone surface 03 on the standard workpiece 0 will be recorded.

[0072] The control system starts the lifting cylinder 52 to separate the measuring cone block 9509 from the standard workpiece 0, then removes the standard workpiece 0 and places the same workpiece 0 to be measured on the base plate 1. As the control system starts the lifting cylinder 52 again, the abutment plate 7 abuts against the top of the workpiece 0 to be measured. At this time, the dial indicator 10 will directly measure the value corresponding to the cone surface of the workpiece 0 to be measured.

[0073] The worker can intuitively determine whether the workpiece 0 to be measured is qualified by comparing the index of the dial indicator 10 of the workpiece 0 to be measured with the index value of the dial indicator 10 at the corresponding position of the standard workpiece 0. At the same time, if the reading of the second scale 9507 of the workpiece to be measured is less than the reading difference at the corresponding position of the standard workpiece 0, the worker can adjust the cutting depth of the turning tool on the lathe to ensure that the workpiece 0 is accurately processed.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
