[0002] With the continuous improvement of precision requirements in mechanical processing, the requirements for the machining accuracy of rotating parts are also getting higher and higher. At present, scholars at home and abroad have conducted extensive research on the measurement of relevant parameters such as diameter, coaxiality, roundness, circular runout, angle, symmetry, etc. of rotating parts. However, most measurement tools can only measure a certain parameter of the rotating body and cannot perform comprehensive measurement of two or more parameters of more complex rotating bodies at the same time.

[0003] For example, for a rotating workpiece with a housing welded with a locking hole seat and a closed air tube, the locking hole seat requires high symmetry, making it difficult to achieve the required accuracy by milling alone after welding. Milling is necessary, and then the milled surfaces on both sides must be precisely filed to meet the required accuracy. Manual filing is labor-intensive and difficult to guarantee accuracy. 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 closed air tube to ensure compliance. Existing measurement tools are unable to meet these requirements for measuring the symmetry of the locking hole seat and the angle between the locking hole seat and the closed air tube.

[0004] Therefore, it is necessary to design a comprehensive measuring tool for filing the rotating workpiece, which can not only conveniently perform filing processing on the locking hole seat of the rotating workpiece, but also measure the symmetry and angle. This is an urgent problem that needs to be solved. Utility Model Content

DETAILED DESCRIPTION

[0027] In the following, reference will be made to the Figure 1-9 The embodiments of the present invention are described. In the following description, the same modules are represented by the same reference numerals. In the case of the same reference numerals, their names and functions are also the same. Therefore, their detailed description will not be repeated.

[0028] In order to make the purpose, technical solutions and advantages of this utility model more clear, the following Figure 1-9It should be understood that the specific embodiments described herein are only used to explain the present invention and do not constitute a limitation of the present invention.

[0029] A comprehensive measuring tool for filing and repairing a rotating workpiece is used to perform filing and repair measurements on a rotating workpiece. Figure 5 As shown, the workpiece to be measured includes a small circular shell 25 and a large circular shell 26 of 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-blocking tube 28.

[0030] like Figure 1 、 Figure 2 As shown, the filing and repairing comprehensive measuring tool includes a base body 1 and a cantilever assembly arranged at the upper end of the base body 1, and the base body 1 is connected to a spindle 2 located below the cantilever assembly, as shown in FIG. Figure 8 As shown, the spindle 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 measured, and the locking section 4 is used to lock the spindle 2 as a whole on the base 1. The positioning section 3 includes a small circular table 23 and a large circular table 24. The small circular table 23 and the large circular table 24 respectively position the small circular shell 25 and the large circular shell 26 of the workpiece to be measured. Figure 1 In the figure, the workpiece to be measured is shown at K. At the same time, the center axis L3 of the spindle 2 coincides with the center axis of the workpiece to be measured, and the adjustment basis for the symmetry of the workpiece to be measured is also to make the center axis L3 of the spindle coincide with the center axis of the workpiece to be measured.

[0031] like Figures 1 to 3 、 Figure 7 As shown, an axial hole 29 is opened on the base body 1, and the positioning section 3 of the main shaft 2 is located on the side of the axial hole 29 away from the locking assembly. A shaft sleeve 7 is arranged in the axial hole 29, and the locking section 4 of the main shaft 2 is installed in the shaft sleeve 7 and extends to the outside of the shaft sleeve 7. A locking assembly is provided on the locking section 4. The locking assembly locks the main shaft 2 to the shaft sleeve 7 and the base body 1 on the outside of the shaft sleeve 7. The inner diameters of the small cone 23 and the large cone 24 gradually increase from the outside toward the shaft sleeve 7.

[0032] The end of the base body 1 is provided with a tail groove 18, which includes a plurality of tail grooves 18 uniformly opened in the circumferential direction at the end of the base body 1 with the central axis L3 as the 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 clamped in the tail groove 18 to lock the spindle 2 and the base body 1. Figure 9 As shown, the stop rod 19 is connected to the tail end of the spindle 2 by rotating at X1, and the rotating handle at X2 is locked in the tail groove 18. The locking assembly also includes a locking member located between the stop rod 19 and the sleeve 7, which locks the spindle 2 and the sleeve 7. Figure 1As shown, the locking member includes a locking nut 21 and a locking screw 22 , and the spindle 2 and the sleeve 7 are locked by the locking nut 21 and the locking screw 22 .

[0033] 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 on the side of the spindle 2. The main cantilever 8 and the side cantilever 9 are installed on the base 1. Figure 7 The cantilever assembly is connected to a measuring assembly 1 5 for limiting the position of the airtight tube 28 and a measuring assembly 2 6 for performing file repair and measurement on the locking hole seat 27. The measuring assembly 1 5 is mounted on the side cantilever 9, and the measuring assembly 2 is mounted on the main cantilever 8. The angle between the locking hole seat 27 and the airtight tube 28 to be measured is the angle α between the central axis L1 of the measuring assembly 1 5 and the central axis L2 of the measuring assembly 2 6. The central axis L3 of the spindle 2 is perpendicular to the central axis L2 of the angle measuring plate 11 or the symmetrical measuring plate.

[0034] like Figure 2 、 Figure 6 As shown, a test slot 10 is provided on the main cantilever 8. Test assembly 2 includes an angle measuring plate 11 and a symmetry measuring plate installed in the test slot 10. When measuring angles, the angle measuring plate 11 is installed in the test slot 10. When testing symmetry, the symmetry measuring plate is installed in the test slot 10. In this embodiment, the angle test is used as an example, and 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 matches the angle measurement requirement, and the width of the inner measuring slot 12 on the symmetry measuring plate matches the symmetry measurement requirement.

[0035] The difference between the angle measuring plate 11 and the symmetrical measuring plate is that the width of the inner groove 12 is different. If the width of the inner groove 12 measured on the angle measuring plate 11 is C1, then C1 is calculated by the tolerance range of the angle α. If the width of the inner groove 12 measured on the symmetrical measuring plate is C2, then C2 is determined by the maximum physical dimension of the width dimension of the locking hole seat 27. The maximum physical dimension is as follows: Figure 4 As shown in C. Figure 6 Taking the angle measuring plate 11 as an example, the angle measuring plate 11 and the width C1 of the measuring inner groove 12 are shown. The symmetrical measuring plate is not shown. The symmetrical measuring plate and the width C2 of the measuring inner groove 12 can be analogous to the angle measuring plate 11.

[0036] like Figure 2 、 Figure 3As shown, a mounting hole is provided on the side cantilever 9, and the measuring component 15 includes a bushing 17 provided in the mounting hole and a connecting rod 13 passed through the bushing 17, the bushing 17 is locked by a large screw 30, and the side of the connecting rod 13 close to the central shaft 2 includes a limit block 14 that can lock the airtight tube 28, and the end of the connecting rod 13 away from the limit block 14 is connected to the handle 31 through a locking pin 32, and the symmetry accuracy and the angle α accuracy are ensured by the measuring components 15 and 26.

[0037] The limit block 14 includes a limit socket, which includes a limit socket 15 close to the side cantilever 9 and a guide port 16 close to the core shaft 2. The limit port 15 is a cylindrical port structure that matches the outer end of the air-blocking tube 28, and the guide port 16 is an eight-shaped port structure. The inner diameter of the upper end of the air-blocking tube 28 is larger than the inner diameter of the lower end. The air-blocking tube 28 has a stepped structure as a whole. The limit port 15 matches the upper small-diameter end of the air-blocking tube 28 to limit the position, and the guide port 16 can match the size of the lower large-diameter end of the air-blocking tube 28, which can assist the limit port 15 in limiting the position without causing interference.

[0038] During actual operation, the workpiece to be measured is first installed on the positioning section 3 of the spindle 2. At this time, the large circular table 24 positions the large circular shell 26, and the small circular table 23 positions the small circular shell 25. Then, the stop rod 19 is rotated and the stop rod 19 is inserted into the tail groove 18 of the base body 1 to lock the spindle 2 and the base body 1.

[0039] Compare the angle measuring plate 11 and the symmetry measuring plate respectively, and use a fine flat file to file the milling surfaces on both sides of the locking hole seat 27 until the milling surfaces on both sides of the locking hole seat 27 meet the requirements, such as Figure 4 As shown, ensure that the dimensions C and D of the workpiece to be measured are qualified. Then, loosen the stop rod 19, lock the air-tight pipe 28 through the limit block 14 and press the workpiece to be measured.

[0040] Next, install the angle measuring plate 11 into the test slot 10 and insert the inner measuring groove 12 of the angle measuring plate 11 into the locking hole seat 27. If it is inserted properly, the angle between the locking hole seat 27 and the air-blocking tube 28 is acceptable. Install the symmetry measuring plate into the test slot 10 and insert the inner measuring groove 12 of the symmetry measuring plate into the locking hole seat 27. If it is inserted properly, the symmetry of the locking hole seat 27 is acceptable.

[0041] In this way, the filing processing of the workpiece to be measured and the comprehensive measurement of angle and symmetry can be completed through the filing comprehensive measuring tool.
