[0039] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0040] Reference Figures 1 to 3In some embodiments of the present invention, a tooling for testing a spindle 400 is disclosed, comprising a base 100, a first support assembly 200, and a second support assembly 300. The base 100 is provided with a guide portion 110, the first support assembly 200 comprises two first support members 210, and the two first support members 210 are respectively slidably mounted on the guide portion 110; the second support assembly 300 comprises two second support members 310, both of which are mounted on the base 100 and located on either side of the guide portion 110. The first support assembly 200 has a first state and a second state, and can switch between the first state and the second state. When the first support assembly 200 is in the first state, the two first support members 210 are close to each other to cooperate in supporting the main shaft 400, and the main shaft 400 can be statically inspected at this time. When the first support assembly 200 is in the second state, the two first support members 210 are separated from each other to avoid the main shaft 400, so that the two second support members 310 can cooperate with each other to support the main shaft 400, and the main shaft 400 can be dynamically inspected at this time. In the technical solution proposed in this application, the main shaft 400 can be subjected to static and dynamic inspections on the same tooling, which reduces the working cycle of the precision inspection of the main shaft 400 and improves the efficiency of the precision inspection of the main shaft 400.

[0041] The two first support members 210 can slide along the guide portion 110, and the two first support members 210 can slide toward each other, so that the two first support members 210 can approach each other, so that the first support assembly 200 is in the first state. The two second support members 210 can also slide back to back, so that the two first support members 210 can move away from each other, so that the first support assembly 200 is in the second state. Figure 4 Since the height of the support position formed by the two first support members 210 is greater than the height of the support position of the two second support members 310 when the first support assembly 200 is in the first state, the first support assembly 200 can support the main shaft 400 alone. When the first support assembly 200 supports the main shaft 400, static detection of the main shaft 400 can be performed; the two first support members 210 can also slide toward each other along the guide portion 110, so that the two first support members 210 move away from each other, so that the two first support members 210 avoid the main shaft 400, and the main shaft 400 can fall to be supported by the second support assembly 300. At this time, dynamic detection of the main shaft 400 can be performed.

[0042] The tooling for detecting the spindle 400 of the present application can perform static detection on the spindle 400 when the two first support members 210 support the spindle 400. By adjusting the positions of the two first support members 210 so that the two second support members 310 support the spindle 400, dynamic detection can be performed on the spindle 400. The spindle 400 only needs to be installed on one device to perform static and dynamic detection, which saves the working cycle of the spindle 400 precision detection and improves the detection efficiency of the spindle 400 precision.

[0043] Reference Figure 3 It should be noted that when the spindle 400 is subjected to static testing, the spindle 400 is supported by the first support assembly 200, and a core rod 410 is installed at the end of the spindle 400. The core rod 410 is rotated, and a lever meter (not shown in the figure) is used to detect the height of each point of the core rod 410 close to and away from the end of the spindle 400, and the value of the lever meter is read to see if it is within the qualified range; the detection head of the lever meter is placed against the flange end face of the spindle 400, the spindle 400 is rotated, and the value of the lever meter is read to see if it is within the qualified range.

[0044] Reference Figure 6 and Figure 7 It should also be noted that when the spindle 400 is dynamically detected, the spindle 400 is supported by the second support assembly 300, the spindle 400 is started by a frequency converter (not shown in the figure), and then the vibration data of the spindle 400 is detected.

[0045] In some embodiments of the present invention, the first support assembly 200 further includes an adjusting member 220, which is connected to the two first support members 210 respectively and can drive the two first support members 210 to slide synchronously in opposite directions, that is, move closer to or away from each other. Figure 1 The adjusting member 220 can drive the two first supporting members 210 to move closer to each other, so that the two first supporting members 210 can cooperate to support the main shaft 400, so as to perform static detection on the main shaft 400. Figure 5 The adjusting member 220 can also drive the two first supporting members 210 to move away from each other to avoid the main shaft 400, so that the two second supporting members 310 can cooperate with each other to support the main shaft 400, thereby enabling dynamic detection of the main shaft 400.

[0046] In some embodiments of the present invention, the adjusting member 220 is a screw, which is respectively threaded through the two first support members 210. By rotating the screw, the two first support members 210 can be driven to slide. The screw has a first threaded portion and a second threaded portion with opposite spiral directions. One of the two first support members 210 is screwed to the first threaded portion, and the other is screwed to the second threaded portion. By rotating the screw, the two first support members 210 can be driven to slide synchronously toward or away from each other. It should be noted that when the first support assembly 200 is in the first state, the two first support members 210 are close to the middle position of the guide portion 110. When the first support assembly 200 is in the second state, the two first support members 210 are located at both ends of the guide portion 110. By rotating the screw, the two first support members 210 are driven to slide toward each other, so that the two first support members 210 can lean against each other, so that the first support assembly 200 is switched to the first state; or the screw is rotated in the opposite direction, the two first support members 210 are driven to slide back to back, so that the two first support members 210 are moved away from each other, so that the first support assembly 200 is switched to the second state.

[0047] Reference Figure 2 In some embodiments of the present invention, the first support assembly 200 further includes two fixing members 230, which are respectively mounted on both sides of the base 100 along the length direction of the screw, and the two ends of the screw are rotatably connected to the fixing members 230. The fixing members 230 can support the screw so that the screw can stably drive the first support member 210 to slide. It should be noted that the fixing member 230 is provided with a mounting hole, in which a bearing 231 is mounted, and the screw is connected to the bearing 231 hole of the bearing 231. By providing the bearing 231, the screw can rotate smoothly.

[0048] Reference Figure 2 In some embodiments of the present invention, the first support assembly 200 further includes a rotating handle 240 connected to the screw. An operator can rotate the screw by rotating the handle 240. The rotating handle 240 also has a grip 241 to facilitate the operator's rotation of the rotating handle 240.

[0049] It should be noted that the screw adopts a trapezoidal thread, which has a self-locking property and can automatically fix the two first support members 210 to facilitate static testing of the main shaft 400 and improve the accuracy of the precision testing of the main shaft 400.

[0050] Reference Figure 2In some embodiments of the present invention, the guide portion 110 comprises two parallel guide rails, and the first support member 210 comprises two parallel sliders. The sliders have a slide groove on one side facing the guide rails, and the two sliders are slidably connected to the two guide rails via the slide grooves, allowing the two sliders to slide synchronously along the guide rails. It should be noted that only one guide rail may be provided, and the two first support members 210 may be slidably mounted on the guide rail.

[0051] In some embodiments of the present invention, the first support member 210 includes a roller 211 for supporting the main shaft 400, and the roller 211 is installed on the opposite side of the two first support members 210. When the first support assembly 200 supports the main shaft 400, the two first support members 210 both support the main shaft 400 via the roller 211. The first support member 210 includes two interconnected sliders, each of which is provided with a roller 211. By providing the roller 211, the friction force applied to the main shaft 400 during rotation can be reduced, and the main shaft 400 rotates more smoothly, which is conducive to improving the accuracy of the precision detection of the main shaft 400. At the same time, the wear of the outer wall of the main shaft 400 can be reduced, thereby improving the quality of the main shaft 400.

[0052] Reference Figure 2 In some embodiments of the present invention, the base 100 is further provided with a positioning portion 120 for mounting the second support member 310. There are two positioning portions 120, and the two second support members 310 are respectively mounted on the two positioning portions 120. It should be noted that the positioning portion 120 is a groove that matches the second support member 310. The lower end of the second support member 310 is inserted into the groove. The bottom wall of the groove is provided with a connecting hole 121. The second support member 310 is fixedly connected to the base 100 by fasteners such as screws or bolts. By providing the positioning portion 120, the positioning and installation of the second support member 310 can be assisted, thereby improving the installation efficiency of the tooling. It should be noted that the positioning portion 120 can also be provided as a positioning rod. The second support member 310 is provided with a positioning hole that matches the positioning rod. The positioning rod is inserted into the positioning hole for positioning.

[0053] Reference Figure 2 In some embodiments of the present invention, the second support member 310 is provided with a V-shaped support portion 311, and the two V-shaped support portions 311 cooperate to support the main shaft 400, so as to perform dynamic detection of the main shaft 400. By providing the V-shaped support portion 311, it is possible to adapt to main shafts 400 of different diameters, thereby improving the applicability of the tooling. A shock absorber 312 is also provided in the V-shaped support portion 311. The second support member 310 supports the main shaft 400 through the shock absorber 312, which can prevent the main shaft 400 from resonating with the base 100. By providing the shock absorber 312, the interference of external factors can be reduced when the main shaft 400 rotates, thereby improving the accuracy of the precision detection of the main shaft 400. It should be noted that the shock absorber 312 can be an elastic rubber material or a plastic material.

[0054] The second embodiment of the present invention is applied to the spindle detection method of the tooling for spindle detection according to the first embodiment, including:

[0055] The two first support members 210 are brought closer together to adjust the first support assembly 200 to the first state. When the first support assembly 200 is in the first state, the two first support members 210 can cooperate with each other to support the main shaft 400, thereby enabling static testing of the main shaft 400. It should be noted that the two first support members 210 can slide toward each other along the guide portion 110, thereby allowing them to approach each other.

[0056] The spindle is placed on the first support assembly 200, with the two first support members 210 cooperating to support the spindle 400. When the first support assembly 200 is in the first state, the height of the support position formed by the two first support members 210 is greater than the height of the support position of the two second support members 310, so the first support assembly 200 can independently support the spindle 400.

[0057] Performing a static test on the main shaft 400. When the first support assembly 200 is in the first state, the two first support members 210 can cooperate with each other to support the main shaft 400. At this time, a static test can be performed on the main shaft 400.

[0058] The two first support members 210 are moved away from each other to adjust the first support assembly 200 to the second state, where the spindle 400 is supported by the two second support members 310. By sliding the two first support members 210 away from each other along the guide portion 110, the two first support members 210 are moved away from each other, and the spindle 400 falls to be supported by the second support assembly 300.

[0059] When the first support assembly 200 is in the second state, the two second support members 310 cooperate with each other to support the main shaft 400 , and at this time, the main shaft 400 can be dynamically tested.

[0060] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
