Description

Technical Field

[0001] The utility model relates to the technical field of rotor measurement, in particular to a numerically controlled inclined car rotor diameter measuring tool. Background Art

[0002] With the rapid development of industrial technology, the rotor, as a core component in many mechanical equipment, has a significant impact on the performance and stability of the entire equipment due to its accuracy and quality. As one of the important parameters of the rotor size, the measurement accuracy of the rotor diameter directly affects the performance evaluation and use effect of the rotor. In the prior art, the diameter of the rotor is generally measured by traditional tools such as micrometers and vernier calipers, as well as high-precision measuring equipment such as coordinate measuring machines. The measurement accuracy of traditional tools is insufficient, and the measurement efficiency of high-precision measuring equipment is low. At the same time, due to the complex shape of the rotor, its outer cylindrical surface may have only one side that can abut against the measuring tool, that is, the other side symmetrical to it is the inclined groove on the rotor, and it is impossible to directly abut on both sides of the rotor to measure the diameter of the rotor.

[0003] Chinese patent CN218511602U discloses a special outer diameter micrometer for odd-numbered grooves, which includes: a base, a curved surface is provided on the base, and the diameter of the virtual circle formed by the curved surface is larger than the diameter of the screw rotor; a measuring rod is vertically arranged on the base, and the axis of the measuring rod is perpendicular to and intersects with the axis of the curved surface; after the user places the odd-numbered groove screw rotor on the curved surface, the odd-numbered groove screw rotor can automatically roll along the curved surface to the lowest position on the curved surface by gravity and align with the measuring rod in the vertical direction, so that the axis of the odd-numbered groove screw rotor is perpendicular to and intersects with the axis of the measuring rod, and at the same time, the outer diameter of the odd-numbered groove screw rotor will first contact the curved surface in a straight line, so that when the lower end of the measuring rod is against the outer diameter of the odd-numbered groove screw rotor, it can be ensured that the measured data is the maximum outer diameter size of the odd-numbered groove screw rotor, thereby facilitating the measurement of the outer diameter size of the odd-numbered groove screw rotor, and the utility model is highly practical.

[0004] However, this technical solution has the following problems: first, the rotor to be measured needs to be repositioned, and this technical solution only relies on gravity to naturally bring the rotor to the lowest position and then clamp it, which is inconvenient to measure and the rotor is easy to deviate during measurement; second, the axis of the measuring rod can only be perpendicular and intersecting with the axis of the rotor when it is in a vertical state, and it needs to be leveled before each use, otherwise measurement errors will occur; third, it can only measure the outer diameter of the straight screw rotor. If the outer circumference of the rotor tends to shrink or expand along the axial direction, it will be in a tilted state after being placed on the base, and its diameter cannot be measured.

[0031] Embodiment 1

[0032] like Figure 1-5 As shown, this embodiment provides a CNC inclined car rotor diameter measuring tool, including a machine platform 1, a rotor 2 horizontally rotatably connected to the machine platform 1, and a CNC turret 3 movably connected to the machine platform 1; the CNC turret 3 is horizontally movably arranged, and a measuring component 4 is installed on its top surface; the measuring component 4 includes a fixed frame 41, an adjustment mechanism 42 connecting the fixed frame 41 and the CNC turret 3, and a measuring device 43 installed on the fixed frame 41, and the measuring part 431 of the measuring device 43 is arranged toward the rotor 2.

[0033] After the rotor 2 is machined, the measuring assembly 4 is directly mounted on the CNC turret 3 to measure the diameter of the rotor 2 without the need to re-clamp and reposition the rotor 2, thereby realizing the function of quickly measuring the diameter of the rotor 2.

[0034] like Figure 2 As shown, the measuring assembly 4 also includes a support arm 44 connecting the measuring device 43 and the fixing frame 41, and the measuring device 43 is longitudinally mounted at one end of the support arm 44. The fixing frame 41 is L-shaped, and its bottom is mounted on the adjusting mechanism 42. The measuring device 43 is a lever dial indicator, and its measuring part 431 is arranged at the bottom of the measuring device 43. After the CNC turret 3 moves the measuring assembly 4 so that the measuring part 431 abuts against the rotor, the adjusting mechanism 42 is adjusted up and down so that the measuring device 43 is at the maximum reading. At this time, the line connecting the abutment point and the center of the circle is the radius in the horizontal direction.

[0035] Through the precise control of the CNC turret 3 and the accurate measurement of the measuring device 43, high-precision measurement of the diameter of the rotor 2 is achieved.

[0036] like Figure 1 As shown, the CNC turret 3 is located on one side of the rotor 2 and is controlled to move parallel to and perpendicular to the axial direction of the rotor 2. It should be noted that the CNC turret 3 is controlled by a handheld computer, and the handheld computer can record the distance that the CNC turret 3 moves parallel to and perpendicular to the rotor 2.

[0037] By installing the measuring component 4 on the CNC turret 3, the purpose of moving the measuring component 4 on the horizontal plane is achieved, so that it can measure multiple points distributed axially on the outer periphery of the rotor 2 to detect whether various parts of the rotor 2 meet the processing accuracy requirements.

[0038] like Figure 3 , 4As shown in the figure, since the numerical control turret 3 can only move on the horizontal plane, and the measuring part 431 of the measuring instrument 43 needs to be adjusted in the vertical direction after contacting the rotor 2 to find the point with the maximum display value, an adjusting mechanism 42 needs to be added to adjust the measuring instrument 43 in the vertical direction. The adjusting mechanism 42 includes an adjusting seat 421, a lifting block 422 arranged vertically on the top of the adjusting seat 421, an adjusting block 423 installed between the lifting block 422 and the adjusting seat 421, and an adjusting rod 424 rotatably connected to the side of the adjusting seat 421. The bottom surface of the lifting block 422 and the top surface of the adjusting block 423 are mutually matching inclined surfaces. The adjusting block 423 is horizontally slidably arranged with the adjusting seat 421, and the adjusting rod 424 is in threaded transmission connection with the adjusting block 423. The cross-section of the adjusting seat 421 is U-shaped, and both sides of the lifting block 422 are in contact with the vertical parts of the adjusting seat 421, so that the lifting block 422 will not shift when lifting. When the adjusting rod 424 rotates, the adjusting block 423 moves horizontally relative to the adjusting seat 421, and the lifting block 422 matching the top surface of the adjusting block 423 rises and falls as the adjusting seat 421 moves. The adjusting range of the lifting block 422 is -10mm to 10mm.

[0039] By setting the adjusting mechanism 42, the up and down adjustment can be carried out after the measuring part 431 contacts the rotor 2, so as to achieve the purpose of accurately finding the measuring point.

[0040] As Figure 1 , 4 shown in the figure, a first fixture 5 and a second fixture 6 are also installed on the machine table 1. The first fixture 5 is the active end, and the second fixture 6 is the driven end. Both ends of the rotor 2 are respectively installed on the first fixture 5 and the second fixture 6. The first fixture 5 is provided with a plurality of clamping blocks 51 evenly distributed in the circumferential direction. The clamping blocks 51 move synchronously in the radial direction to clamp one end of the rotor 2. The second fixture 6 includes a mounting seat 61 installed on the machine table 1, a telescopic shaft 62 slidably arranged in the mounting seat 61, and a center point 63 rotatably connected to one end of the telescopic shaft 62. The first fixture 5 and the second fixture 6 can position rotors 2 of various specifications. A guide groove 621 is formed on the side surface of the telescopic shaft 62, and the guide groove 621 is parallel to the telescopic direction. A guide member 64 matching the guide groove 621 is installed on the mounting seat 61. The other end of the telescopic shaft 62 is in transmission connection with a screw rod 65. The screw rod 65 is rotatably connected to the mounting seat 61, and a hand wheel 66 is installed at the outer end of the screw rod 65.

[0041] By setting the first fixture 5 and the second fixture 6 to position the rotor 2 during the processing and measuring processes, the rotor 2 is kept in an axially horizontal state during the processing and measuring processes, and the rotor will not shift during the measurement, ensuring the reliability of the measurement results.

[0042] The measurement method of this embodiment is as follows: a conventional tool such as a micrometer or a vernier caliper is clamped on both sides of the rotor shaft 2 to quickly measure the rotor diameter. Figure 5 As shown, point o is the axis, and with the axis of the rotor 2 as the reference, the measuring device 43 first contacts the axis of the rotor 2, point a is the contact point between the measuring device 43 and the axis of the rotor 2, and point c is the initial position of the measuring part 431 when the measuring device 43 measures the axis diameter of the rotor 2, so the length oa is equal to the axis radius of the rotor 2, and the adjusting rod 424 of the adjusting mechanism 42 is rotated to fine-tune the height of the measuring device 43 so that it stops at the maximum value displayed and records the value, at which point oa is in a horizontal state, and the projection of the distance between ac on oa is the deviation value between the initial position of the measuring part 431 and the axis radius of the rotor 2, that is, the display value of the measuring device 43 in the current state. It should be noted that, because the measurement of this embodiment is based on the axis of the rotor 2, point c can be zeroed so that point a coincides with point c, specifically, when the measuring device 43 is at the maximum value displayed, the numerical control turret 3 is adjusted to make the display value of the measuring device 43 return to zero, that is, ac=0, to facilitate subsequent calculations.

[0043] After the above data are recorded, the handheld machine is used to control the CNC turret 3 to drive the measuring device 43 to move until it abuts against the outer periphery of the rotor 2, and the distance of the axial movement of the CNC turret 3 perpendicular to the rotor 2 displayed on the handheld machine is recorded. Point b is the abutment point of the measuring device 43 and the outer periphery of the rotor 2, and point d is the initial position of the measuring part 431 when the measuring device 43 measures the outer periphery of the rotor 2. Therefore, cd is equal to the distance of the axial movement of the CNC turret 3 perpendicular to the rotor 2. Turn the adjustment rod 424 of the adjustment mechanism 42 to fine-tune the height of the measuring device 43 so that it stops at the maximum value displayed. At this time, ob is in a horizontal state, and the projection of the distance between bd on ob is the deviation value between the initial position of the measuring part 431 and the outer radius of the rotor 2, that is, the displayed value of the measuring device 43 in the current state.

[0044] By projecting the five points o, a, b, c, and d onto the same horizontal line, it can be seen that the outer radius of the rotor ob=oa+cd-ac+bd, and its diameter is 2ob.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
