Description

Technical Field

[0001] This invention relates to the field of measuring tooling technology, specifically providing a comprehensive measuring tool for filing and repairing rotating workpieces and its operating method. Background Technology

[0002] With the increasing demands for precision in machining, the requirements for machining accuracy of rotating parts are also getting higher and higher. At present, scholars at home and abroad have conducted a lot of research on the measurement of related parameters such as diameter, coaxiality, roundness, circular runout, angle, and symmetry of rotating parts. However, most measuring tools can only measure one parameter of the rotating body and cannot simultaneously measure two or more parameters of a more complex rotating body.

[0003] For a rotating workpiece with a locking hole seat and a vent tube welded to its shell, the high symmetry precision of the locking hole seat makes it difficult to achieve the required accuracy by milling alone after welding. It is necessary to mill the surface and then manually file the milled surfaces on both sides to achieve the required precision. This manual filing method is labor-intensive and its accuracy is difficult to guarantee. Furthermore, after filing, it is necessary to measure both the symmetry of the locking hole seat and the angle between the locking hole seat and the vent tube to ensure they are within acceptable limits. Existing measuring tools are insufficient to meet the measurement requirements for both the symmetry of the locking hole seat and the angle between the locking hole seat and the vent tube.

[0004] Therefore, the urgent problem to be solved is to design a comprehensive tool for filing and repairing rotating workpieces that can both facilitate the filing and repair of locking holes and measure symmetry and angles. Summary of the Invention

[0005] To solve the above problems, this invention provides a comprehensive tool for filing and repairing rotating workpieces and its operating method. It can file and repair the milled surfaces on both sides of the locking hole seat, and can also measure the angle between the locking hole seat and the air-sealing pipe, as well as the symmetry of the locking hole seat.

[0006] The present invention provides a comprehensive measuring tool for filing and repairing rotating workpieces, specifically including a base and a cantilever assembly disposed on the upper end of the base. A mandrel located below the cantilever assembly is connected to the base. The mandrel includes a positioning section for positioning the workpiece to be measured and a locking section for locking the mandrel as a whole onto the base. A locking component is provided on the locking section. The workpiece to be measured is fitted onto the positioning section. A measuring component one that cooperates with the air-sealing tube for limiting and a measuring component two that cooperates with the locking hole seat for filing and repair measurement are connected to the cantilever assembly.

[0007] Furthermore, the base has a shaft hole and a bushing is provided inside the shaft hole. The locking section of the spindle is installed inside the bushing and extends to the outside of the bushing. The locking assembly locks the spindle to the bushing and the base on the outside of the bushing. The positioning section of the spindle is located on the side of the shaft hole away from the locking assembly.

[0008] Furthermore, the cantilever assembly includes a main cantilever located above the spindle and a side cantilever located to the side of the spindle. Measurement component one is mounted on the side cantilever, and test component two is mounted on the main cantilever.

[0009] Furthermore, a test slot is provided on the main cantilever, and the second test component includes an angle measuring plate and a symmetry measuring plate installed in the test slot; both the angle measuring plate and the symmetry measuring plate have inner measuring slots, the width of the inner measuring slot on the angle measuring plate is set to match the angle measurement requirements, and the width of the inner measuring slot on the symmetry measuring plate is set to match the symmetry measurement requirements.

[0010] Furthermore, let the width of the inner groove on the angle measuring plate be C1, then C1 is calculated from the tolerance range of the included angle α; let the width of the inner groove on the symmetry measuring plate be C2, then C2 is determined from the maximum material dimension of the width of the locking hole seat.

[0011] Furthermore, a mounting hole is provided on the side cantilever, and the measuring component includes a bushing provided in the mounting hole and a connecting rod passing through the bushing. The side of the connecting rod near the spindle includes a limiting block that can lock the air-closing tube.

[0012] Furthermore, the limiting block includes a limiting port, which includes a limiting port near the side cantilever and a guiding port near the spindle; the limiting port is a cylindrical port structure that matches the outer end of the breech tube, and the guiding port is a figure-eight port structure.

[0013] Furthermore, a tail groove is provided at the end of the seat body, and the locking assembly includes a stop rod rotatably connected to the locking section of the spindle. The stop rod can rotate on the spindle and be locked in the tail groove to lock the spindle and the seat body. The locking assembly also includes a locking member located between the stop rod and the bushing, and the locking member locks the spindle and the bushing together.

[0014] Furthermore, the positioning section of the mandrel includes a small truncated cone and a large truncated cone with gradually increasing inner diameter from the outside towards the bushing. The small truncated cone and the large truncated cone are used to position the small and large circular shells of the workpiece to be measured, respectively. The central axis L3 of the mandrel coincides with the central axis of the workpiece to be measured, and the central axis L3 of the mandrel is perpendicular to the central axis L2 of the angle measuring plate or symmetry measuring plate.

[0015] A method for operating a comprehensive filing and repair measuring tool for a rotating workpiece, comprising the following steps:

[0016] S1: Install the workpiece to be tested onto the positioning section of the mandrel. At this time, the large circular platform positions the large circular shell, and the small circular platform positions the small circular shell.

[0017] S2: Rotate the stop rod and make it engage in the groove at the tail of the seat to lock the spindle and the seat.

[0018] S3: Compare with the angle measuring plate and the symmetry measuring plate respectively, and file the milled surfaces on both sides of the locking hole seat until the milled surfaces on both sides of the locking hole seat meet the requirements.

[0019] S4: Release the stop rod, lock the air-sealing tube with the limit block and press the workpiece to be tested;

[0020] S5: Install the angle measuring plate into the test slot, insert the measuring inner groove of the angle measuring plate into the locking hole seat. If it is inserted in place, the angle between the locking hole seat and the air-sealing tube is qualified.

[0021] Install the symmetry measuring plate into the test slot, and insert the measuring inner groove of the symmetry measuring plate into the locking hole seat. If it is inserted in place, the symmetry of the locking hole seat is qualified.

[0022] Compared with the prior art, the present invention can achieve the following beneficial effects: The rotary workpiece filing and repair integrated measuring tool and its operation method in the present invention can make the design datum and measurement datum coincide after the workpiece is installed and positioned. The angle measuring plate and symmetry measuring plate are compared on the measuring tool to file and repair the workpiece to be measured, and then the angle and symmetry are measured. The measurement of this solution is precise and reliable, the operation is simple, and it can realize multi-functional integrated operation. Attached Figure Description

Detailed Implementation

[0033] The appendix will be referenced below. Figure 1-9 Embodiments of the present invention are described below. In the following description, the same modules are denoted by the same reference numerals. Where the same reference numerals are used, their names and functions are also the same. Therefore, their detailed description will not be repeated.

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the following description is provided in conjunction with the appendix. Figure 1-9 The present invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and do not constitute a limitation thereof.

[0035] A comprehensive measuring tool for filing and repairing rotating workpieces, used for measuring the filing and repair of workpieces with rotating structures, such as... Figure 5 As shown, the workpiece to be tested includes a small circular shell 25 and a large circular shell 26 with a rotating body structure. The inner diameter of the small circular shell 25 is smaller than the inner diameter of the large circular shell 26. The connection between the small circular shell 25 and the large circular shell 26 includes a locking hole seat 27 and an air-sealing tube 28.

[0036] like Figure 1 , Figure 2 As shown, the filing and finishing tool includes a base 1 and a cantilever assembly disposed on the upper end of the base 1. A spindle 2 located below the cantilever assembly is connected to the base 1. Figure 8 As shown, the mandrel 2 includes a positioning section 3 and a locking section 4. The positioning section 3 is used to position and install the workpiece to be tested, and the locking section 4 is used to lock the mandrel 2 as a whole onto the base 1. The positioning section 3 includes a small frustum 23 and a large frustum 24, which are used to position the small circular shell 25 and the large circular shell 26 of the workpiece to be tested, respectively. Figure 1 In the diagram, the workpiece to be tested is shown at point K. Simultaneously, the central axis L3 of the mandrel 2 coincides with the central axis of the workpiece to be tested. The adjustment datum for the symmetry of the workpiece to be tested is also to ensure that the central axis L3 of the mandrel coincides with the central axis of the workpiece to be tested.

[0037] like Figures 1 to 3 , Figure 7 As shown, a shaft hole 29 is provided on the base 1. The positioning section 3 of the spindle 2 is located on the side of the shaft hole 29 away from the locking assembly. A bushing 7 is provided in the shaft hole 29. The locking section 4 of the spindle 2 is installed in the bushing 7 and extends to the outside of the bushing 7. A locking assembly is provided on the locking section 4. The locking assembly locks the spindle 2 to the bushing 7 and the base 1 on the outside of the bushing 7. The inner diameter of the small truncated cone 23 and the large truncated cone 24 gradually increases from the outside towards the bushing 7.

[0038] The end of the base 1 is provided with a tail groove 18, which includes multiple grooves evenly spaced circumferentially at the end of the base 1 with the central axis L3 as a reference. The locking assembly includes a stop rod 19 rotatably connected to the locking section 4 in the spindle 2. The stop rod 19 can rotate on the spindle 2 and be engaged in the tail groove 18 to lock the spindle 2 and the base 1. Figure 9 As shown, the stop rod 19 is rotatably connected to the tail end of the spindle 2 via X1, and the rotating handle at X2 is engaged in the tail groove 18. The locking assembly also includes a locking member located between the stop rod 19 and the bushing 7, which locks the spindle 2 and the bushing 7 together. Figure 1 As shown, the locking components include a locking nut 21 and a locking screw 22, which lock the spindle 2 and the bushing 7 together.

[0039] like Figures 1 to 3 As shown, the cantilever assembly includes a main cantilever 8 located above the spindle 2 and a side cantilever 9 located to the side of the spindle 2. The main cantilever 8 and the side cantilever 9 are mounted on the seat 1. Figure 7 Point Y is shown. The cantilever assembly is connected to a measuring component 5 that cooperates with the air-closing tube 28 for limiting and a measuring component 6 that cooperates with the locking hole seat 27 for filing and measurement. The measuring component 5 is set on the side cantilever 9, and the measuring component 6 is set on the main cantilever 8. The angle between the locking hole seat 27 and the air-closing tube 28 to be measured is the angle α between the central axis L1 of the measuring component 5 and the central axis L2 of the measuring component 6. The central axis L3 of the mandrel 2 is perpendicular to the central axis L2 of the angle measuring plate 11 or the symmetrical measuring plate.

[0040] like Figure 2 , Figure 6As shown, a test slot 10 is provided on the main cantilever 8. The second test component includes an angle measuring plate 11 and a symmetry measuring plate installed in the test slot 10. When measuring the angle, the angle measuring plate 11 is installed in the test slot 10. When testing the symmetry, the symmetry measuring plate is installed in the test slot 10. In this embodiment, taking the angle test as an example, the angle measuring plate 11 is installed in the test slot 10. Both the angle measuring plate 11 and the symmetry measuring plate have inner measuring slots 12. The width of the inner measuring slot 12 on the angle measuring plate 11 is set to match the angle measurement requirements, and the width of the inner measuring slot 12 on the symmetry measuring plate is set to match the symmetry measurement requirements.

[0041] The difference between the angle measuring plate 11 and the symmetry measuring plate lies in the different width dimensions of the inner groove 12 they measure. Let C1 be the width of the inner groove 12 measured on the angle measuring plate 11, then C1 is calculated from the tolerance range of the included angle α. Let C2 be the width of the inner groove 12 measured on the symmetry measuring plate, then C2 is determined by the maximum material dimension of the width of the locking hole seat 27. The maximum material dimension is as follows: Figure 4 As shown in C. Figure 6 Taking the angle measuring plate 11 as an example, the width C1 of the angle measuring plate 11 and its measuring inner groove 12 is shown. The symmetrical measuring plate is not shown. The width C2 of the symmetrical measuring plate and its measuring inner groove 12 can be compared with the angle measuring plate 11.

[0042] like Figure 2 , Figure 3 As shown, the side cantilever 9 has a mounting hole. The measuring component 1 5 includes a bushing 17 located in the mounting hole and a connecting rod 13 passing through the bushing 17. The bushing 17 is locked by a large screw 30. The side of the connecting rod 13 near the spindle 2 includes a limiting block 14 that can lock the air-sealing tube 28. The end of the connecting rod 13 away from the limiting block 14 is connected to a handle 31 by a locking pin 32. The symmetry accuracy and the angle α accuracy are ensured by the measuring component 1 5 and the measuring component 2 6.

[0043] The limiting block 14 includes a limiting port, which includes a limiting port 15 near the side cantilever 9 and a guide port 16 near the spindle 2. The limiting port 15 is a cylindrical structure that matches the outer end of the air-closing tube 28, and the guide port 16 is a figure-eight structure. The inner diameter of the upper end of the air-closing tube 28 is larger than the inner diameter of the lower end. The air-closing tube 28 has a stepped structure. The limiting port 15 matches and limits the upper small-diameter end of the air-closing tube 28, and the guide port 16 can match the size of the lower large-diameter end of the air-closing tube 28. It can assist the limiting port 15 in limiting without causing interference.

[0044] A method for operating a comprehensive filing and repair measuring tool for a rotating workpiece, comprising the following steps:

[0045] S1: Install the workpiece to be tested onto the positioning section 3 of the mandrel 2. At this time, the large circular platform 24 positions the large circular shell 26, and the small circular platform 23 positions the small circular shell 25.

[0046] S2: Rotate the stop rod 19 so that the stop rod 19 is engaged in the tail groove 18 of the seat body 1, thereby locking the spindle 2 and the seat body 1.

[0047] S3: Compare the milled surfaces on both sides of the locking hole seat 27 with the angle measuring plate 11 and the symmetry measuring plate, respectively, using a fine-tipped flat file until the milled surfaces on both sides of the locking hole seat 27 meet the requirements. Figure 4 As shown, ensure that the dimensions C and D of the workpiece to be tested are within acceptable limits.

[0048] S4: Release the stop rod 19, lock the air-sealing tube 28 through the limit block 14 and press the workpiece to be tested.

[0049] S5: Install the angle measuring plate 11 into the test slot 10, insert the measuring inner slot 12 of the angle measuring plate 11 into the locking hole seat 27. If it is inserted in place, the angle between the locking hole seat 27 and the air-closing tube 28 is qualified.

[0050] Install the symmetry measuring plate into the test slot 10, and insert the measuring inner slot 12 of the symmetry measuring plate into the locking hole seat 27. If it is inserted in place, the symmetry of the locking hole seat 27 is qualified.

[0051] This allows for the filing and finishing of the workpiece under test, as well as the comprehensive measurement of angles and symmetry, using a filing and finishing comprehensive measuring tool.
