Description

Technical Field

[0001] This utility model relates to the field of testing equipment, specifically a testing device for rotating equipment. Background Technology

[0002] In China, for small metal processing products or sheet metal stamping parts of a certain size, flatness inspection typically uses coordinate measuring machines (CMMs) or machining centers; larger parts can be inspected using gantry milling machines. Roundness inspection of metal workpieces usually uses an inside dial indicator. However, current quality inspection systems and conventional methods and existing equipment can only inspect equipment parts of a certain specification and size.

[0003] When manufacturing industries encounter large rotating products or engineering steel structures, conventional quality inspection equipment struggles to provide effective testing with detailed data ranges. In such cases, testing costs are high, or it's difficult to collect high-precision data, and there are no effective testing methods available. Utility Model Content

[0004] To address the above problems, this utility model provides a rotating body equipment testing device that can simultaneously solve the problems of testing quality and testing cost for large rotating body products.

[0005] According to a first aspect of this disclosure, a rotating body equipment testing device is provided, comprising: a flatness testing module and a coaxiality testing module, both of which employ a pre-compressed spring-type displacement measurement structure; the flatness testing module abuts against the radial plane of the rotating body equipment for collecting flatness data of the radial plane; the coaxiality testing module abuts against the outer circumferential surface of the rotating body equipment for collecting coaxiality data of the outer circumferential surface.

[0006] In some possible implementations, the flatness detection module employs a pre-compressed spring-type displacement measurement structure, including a first damping housing assembly, a ball head, a damping rod, a spring, a first detection pointer, and a first scale. The ball head is in direct contact with the radial plane. One end of the damping rod extends from the first damping housing assembly and connects to the ball head, and the damping rod has a convex ring. The spring is sleeved on the outer periphery of the convex ring of the damping rod on the side away from the ball head and is located inside the first damping housing assembly. One end of the spring abuts against the convex ring, and the other end abuts against the end of the first damping housing assembly away from the ball head. The first detection pointer is fixedly connected to the damping rod and moves relative to the first scale, displaying a reading of the flatness data based on the first scale.

[0007] In some possible implementations, the spring is in a compressed state when the rotation of the rotating device is not initiated.

[0008] In some possible implementations, the coaxiality detection module includes a second damping housing assembly, a force-bearing plate, a damping component, a second detection pointer, and a second scale. The force-bearing plate is in direct contact with the outer circumferential surface of the rotating body device. The damping component is rod-shaped, with one end extending from the second damping housing assembly and connected to the force-bearing plate, and the other end elastically extendable within the second damping housing assembly. The second detection pointer is fixedly connected to the damping component. The second detection pointer moves relative to the second scale, displaying the coaxiality data reading based on the second scale.

[0009] In some possible implementations, the damping components are in an elastically compressed state when the rotation of the rotating device is not initiated.

[0010] In some possible implementations, the coaxiality detection module also includes two positioning guide rods, which are respectively arranged opposite to each other and connected to the two opposite ends of the force-bearing plate.

[0011] In some possible implementations, the testing device further includes: a detachable support frame for fixing the flatness testing module above the radial plane; and an adjustable support assembly for fixing the coaxiality testing module to the side of the rotating body device.

[0012] Implementing this disclosure has the following beneficial effects: This disclosure achieves high-precision detection of key dimensional and positional tolerances (flatness and roundness) of large rotating equipment through spring preload and mechanical lever / guide structure, solves the problem of large workpiece inspection, significantly reduces inspection costs and improves the reliability of quality control.

[0027] In this article, the "pre-compressed spring displacement measurement structure" refers to a structure that uses a compressed spring to hold the measuring head against the surface to be measured during measurement, thereby obtaining information on the flatness or coaxiality of the surface to be measured.

[0028] Figure 1 A schematic diagram of the overall structure of a rotating body equipment detection device 100 provided for an embodiment of this utility model is shown below. Figure 1 As shown, the rotating body equipment testing device 100 provided in this embodiment includes a flatness testing module 200 and a coaxiality testing module 300. Both the flatness testing module 200 and the coaxiality testing module 300 adopt a pre-compressed spring type displacement measurement structure; the flatness testing module 200 abuts against the radial plane of the rotating body equipment and is used to collect the flatness data of the radial plane; the coaxiality testing module 300 abuts against the outer circumferential surface of the rotating body equipment and is used to collect the coaxiality data of the outer circumferential surface.

[0029] Figure 2 This is a schematic diagram of the overall structure of a flatness detection module 200 provided for an embodiment of this utility model. (See attached diagram.) Figure 2As shown, the flatness detection module 200 in this embodiment adopts a pre-compressed spring-type displacement measurement structure, which includes a ball head 1, an elastic measurement structure, and a displacement indicating unit. The ball head 1 is in direct contact with the plane to be measured (i.e., the radial plane). The elastic measurement structure consists of a first nylon guide sleeve 2, a shock-absorbing rod 3, a first shock-absorbing housing assembly 4, and a spring 5. The ball head 1 is located at the end of the shock-absorbing rod 3 extending from the first nylon guide sleeve 2. The first nylon guide sleeve 2 is fitted around the outer periphery of the convex ring of the shock-absorbing rod 3 on the side near the ball head 1. The spring 5 is fitted around the outer periphery of the convex ring of the shock-absorbing rod 3 on the side away from the ball head 1. One end of the spring 5 abuts against the convex ring, and the other end abuts against the end of the first shock-absorbing housing assembly 4 away from the ball head 1. The displacement indicating unit consists of a first scale 6 fixed on the first shock-absorbing housing assembly 4, a first detection pointer 7 that moves synchronously with the shock-absorbing rod 3, and a first connecting assembly 8.

[0030] The damping rod 3 can be based on the undulations of the plane under test (as the rotating body rotates, if there are uneven parts on the plane under test, it will cause the plane under test to undulate vertically). Figure 2 The vertical movement of the pointer further drives the first detection pointer 7 to move vertically relative to the first scale 6, thereby indicating the flatness of the plane to be measured. The first connecting component 8 is used to fix the flatness detection module 200.

[0031] In this embodiment of the disclosure, the spring is initially in a compressed state, so that the ball head 1 is in close contact with the plane to be measured, and the first detection pointer 7 points to the zero point of the first scale 6.

[0032] In some possible embodiments, when the measured plane has a positive tolerance runout, the spring is further compressed, and the first detection pointer 7 moves upward; when the measured plane has a negative tolerance runout, the spring releases the compression, and the first detection pointer 7 moves downward.

[0033] In some possible embodiments, the rotating body equipment testing device 100 further includes a detachable support frame for fixing the flatness testing module 200 above the plane to be tested.

[0034] refer to Figure 1 and Figure 2In this embodiment, the flatness detection module 200 is mounted on one side of the rotational radial plane of the rotating body equipment via an adjustable support frame, ensuring that the ball head 1 is in close contact with the plane to be detected. When the spring 5 inside the first shock-absorbing housing assembly 4 is in contact with the plane to be detected, the spring is in a compressed state (at this time, the engagement position of the first detection pointer 7 and the first scale 6 is 0). Thus, when the large rotating body equipment rotates, if there is a positive tolerance runout in the flatness, the first detection pointer 7 moves upward relative to the first scale 6 (the steel ruler remains stationary). If there is a negative tolerance runout in the flatness, since the spring 5 is in a compressed state, the first detection pointer 7 can move downward relative to the first scale 6 (the spring 5 releases its compression, and the spring 5 was originally fixed in compression), thus obtaining the runout amount and consequently the flatness data.

[0035] Figure 3 A schematic diagram of the overall structure of the coaxiality detection module 300 of the rotating body equipment detection device 100 provided in this embodiment of the utility model. Figure 4 A schematic diagram along direction A of the rotating body equipment detection device 100 provided for an embodiment of this utility model. (See diagram below.) Figure 3 , Figure 4 As shown, in some possible embodiments, the coaxiality detection module 300 adopts a pre-compressed spring-type displacement measurement structure, which includes a force-bearing plate 9, a displacement conversion structure, and a displacement indicating unit. The force-bearing plate 9 is in direct contact with the radial outer circumferential surface of the rotating device.

[0036] The displacement conversion structure consists of a second nylon guide sleeve 10, a third nylon guide sleeve 11, a positioning guide rod 12, a second damping housing assembly 13, and a damping assembly 14. The second nylon guide sleeve 10 is fixed and limited by a second connecting assembly 17 and is fitted around the outer periphery of the rod-shaped damping assembly 14, restricting the movement direction of the damping assembly 14. The second damping housing assembly 13 is located on the side of the second nylon guide sleeve 10 away from the force-bearing plate 9 and surrounds the main body of the damping assembly 14. A spring is located between the second damping housing assembly 13 and the damping assembly 14 to provide restoring force for the elastic expansion and contraction of the damping assembly 14. The third nylon guide sleeve 11 is located at the end of the damping assembly 14 away from the force-bearing plate 9, and the third nylon guide sleeve 11 and the second nylon guide sleeve 10 limit and guide the damping assembly 14 from both ends.

[0037] The displacement indicator unit consists of a second scale 15 fixed on the second shock absorber housing assembly 13 and a second detection pointer 16 linked to the shock absorber assembly 14.

[0038] When the rotating device rotates, if the outer circumferential surface of the rotating device is not perfectly coaxial, the outer diameter of the outer circumferential surface will fluctuate as the rotating device rotates, thereby causing the force plate 9 to move along... Figure 3It moves back and forth in the left and right directions. Since the force plate 9 is fixed to the shock absorption component 14, the shock absorption component 14 can move in the left and right directions, thereby driving the second detection pointer 16 to move back and forth in the radial direction of the rotation of the rotating body equipment.

[0039] During measurement, the spring of the shock absorption assembly 14 is initially in a compressed state. After the force plate 9 is pressed tightly against the radial outer end face of the rotating body equipment, the second detection pointer 16 is zeroed and points to the zero point of the second scale 15.

[0040] In some possible embodiments, the displacement conversion structure satisfies the following: when the outer circumferential surface of the rotating body device has a positive tolerance runout, the compression of the damping component 14 increases and the second detection pointer 16 moves to the left; when the outer circumferential surface of the rotating body device has a negative tolerance runout, the compression of the damping component 14 decreases and the second detection pointer 16 moves to the right.

[0041] In some possible embodiments, the detection device also includes an adjustable support assembly for fixing the coaxiality detection module 300 to the side of the rotating body.

[0042] In this embodiment, the coaxiality detection module 300 can be fixed to the side of the large rotating body equipment to be tested. The fixing method can be combined with the characteristics of the equipment, such as directly fixing it to the equipment structure, or temporarily adding a simple support component and then fixing the coaxiality detection module 300 to the added support component. The fixing method is relatively flexible.

[0043] In this embodiment, the front force plate 9 of the coaxiality detection module 300 is tightly fitted to the outer circumferential surface of the large rotating body to be tested, and the spring inside the second shock-absorbing housing assembly 13 needs to be in a certain compressed state before the second detection pointer 16 is returned to zero. Thus, when the large rotating body rotates, if there is positive tolerance runout on the outer circumferential surface, the second detection pointer 16 moves to the left relative to the second scale 15; if there is negative tolerance runout on the outer circumferential surface, the second detection pointer 16 moves to the right relative to the second scale 15 because the spring is in a compressed state. This method allows for the acquisition of positive and negative tolerance data for the large rotating body. The change in the positive and negative tolerance values ​​represents the runout of the outer circumferential surface of the large rotating body. By calculating the runout, coaxiality (or roundness) data can be further obtained.

[0044] By simultaneously equipping a flatness detection module 200 and a coaxiality detection module 300 in a rotating equipment testing device 100, flatness and coaxiality testing can be performed simultaneously, improving testing efficiency. Furthermore, both the flatness detection module 200 and the coaxiality detection module 300 adopt a pre-compressed spring displacement measurement structure, allowing for component sharing and effectively reducing design and manufacturing costs. Moreover, either flatness or coaxiality testing can provide information for the positioning of the rotating equipment, helping users identify whether the deviation detected by the other should be attributed to the skewness of the rotating shaft or the coaxiality or flatness deviation of the rotating equipment itself.

[0045] The above are merely optional embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
