[0020] Reference Figures 1 to 5This application provides a comprehensive inspection fixture for shaft parts, including: a base 100; a support mechanism 200 disposed on the base 100, the support mechanism 200 supporting the shaft 600 to be measured; a rotation mechanism 300 including a fixed seat 310 and a tip 320, the fixed seat 310 being slidably disposed at both ends of the support mechanism 200, the fixed seat 310 sliding to approach or move away from the support mechanism 200, the tip 320 being rotatably disposed on the fixed seat 310, the tip 320 being used to embed into the shaft holes at both ends of the shaft 600 to be measured; and a measuring mechanism including an outer diameter measuring component 410 and a circular runout measuring component 420, the outer diameter measuring component 410 being slidably disposed on one side of the support mechanism 200, the outer diameter... The measuring component 410 slides to approach or move away from the supporting mechanism 200. The outer diameter measuring component 410 includes multiple sets of outer diameter measuring modules 411. The multiple sets of outer diameter measuring modules 411 measure the diameter of the four shaft segments and the grooves at both ends of the shaft rod 600 to be measured. Each set of outer diameter measuring modules 411 is connected to a first sensor. The circular runout measuring component 420 is located on the other side of the supporting mechanism 200. The circular runout measuring component 420 includes a circular runout measuring module 421. The circular runout measuring module 421 is used to measure the circular runout of the four shaft segments of the shaft rod 600 to be measured. The circular runout measuring module 421 is connected to a second sensor. The microcontroller 500 is connected to the first sensor and the second sensor respectively.

[0021] During measurement, the standard parts are first used for calibration; then the shaft 600 to be measured is placed on the support mechanism 200; next, the fixed seat 310 slides to approach the support mechanism 200, so that the tip 320 approaches the support mechanism 200 and is embedded in the shaft holes at both ends of the shaft 600 to be measured; then the outer diameter measuring assembly 410 slides to approach the support mechanism 200, so that multiple outer diameter measuring modules 411 respectively measure the diameter of the four shaft segments and the grooves at both ends of the shaft 600 to be measured, and transmit the measurement results to the microcontroller 500 through the first sensor; the rotating mechanism 300 drives the shaft 600 to be measured to rotate, and the circular runout measuring module 421 measures the circular runout of the four shaft segments of the shaft 600 to be measured, and transmits the measurement results to the microcontroller 500 through the second sensor. The comprehensive inspection fixture for shaft parts described in this application can simultaneously measure the diameter of the four shaft segments and the grooves at both ends of the shaft 600 to be tested, as well as the circular runout of the four shaft segments, without the need for manual operation. This not only improves measurement efficiency but also enhances measurement accuracy, ensuring product quality.

[0022] The microcontroller's control method is simply trigger control. Therefore, the microcontroller's control method is not within the scope of this application and belongs to the prior art. This application mainly protects the connection relationship between the various components.

[0023] Reference Figure 1It is easy to understand that the base 100 is also provided with a placement seat 150 for placing standard parts. The structure of the standard parts is the same as that of the shaft to be tested 600, and the diameters of the four shaft segments and the grooves at both ends of the standard parts, as well as the circular runout of the four shaft segments, all meet the requirements. Furthermore, the base 100 is provided with lifting holes 160, which allows for the transport of shaft-type parts using a comprehensive inspection fixture, improving work efficiency.

[0024] Reference Figure 2 The outer diameter measuring assembly 410 also includes a mounting base 412, which is slidably disposed on the base 100. Multiple sets of outer diameter measuring modules 411 are arranged on the base 100. Each outer diameter measuring module 411 includes an upper measuring part 413 and a lower measuring part 414, which are arranged vertically on the mounting base 412. The upper measuring part 413 and the lower measuring part 414 cooperate to measure the outer diameter of shaft-like parts. By simultaneously placing multiple sets of outer diameter measuring modules 411 on the mounting base 412, when the mounting base 412 slides close to the support mechanism 200, the multiple sets of outer diameter measuring modules 411 respectively measure the diameter of the four shaft segments and the grooves at both ends of the shaft 600 to be measured. The structure is simple, easy to operate, and has low production costs. Furthermore, the mounting base 412 is provided with an adjustment hole, which is an elongated hole. The upper measuring part 413 and the lower measuring part 414 are respectively provided in the adjustment hole, so that the distance between the upper measuring part 413 and the lower measuring part 414 can be adjusted to adapt to different specifications of the shaft rod 600 to be measured, expand the scope of application, and reduce production costs.

[0025] It is conceivable that the base 100 is equipped with a first translation component 110, and the mounting base 412 is disposed on the first translation component 110. The first translation component 110 drives the mounting base 412 to slide, and the first translation component 110 is connected to the microcontroller 500. Specifically, the first translation component 110 includes a slide rail, a slider, and a first cylinder. The slide rail is disposed on the base 100, and the slider is disposed on the mounting base 412. The slider and the slide rail are connected in cooperation. The telescopic end of the first cylinder is connected to the mounting base 412. When the first cylinder operates, it causes the mounting base 412 to slide along the slide rail, so that the outer diameter measuring component 410 moves closer to or further away from the support mechanism 200, thereby realizing the diameter measurement of the four shaft segments and the grooves at both ends of the shaft rod 600 to be measured. It is easy to understand that the base 100 is provided with a limiting component, which is located on the side of the first translation component 110 near the support mechanism 200. The limiting component is used to restrict the sliding position of the first translation component 110, thereby avoiding damage to the outer diameter measuring component 410, extending its service life, and improving the measurement accuracy.

[0026] Of course, the first translation component 110 can also be implemented by a structure such as a lead screw and nut or a gear and rack, and this application does not limit it.

[0027] Reference Figure 3 Two sets of circular runout measurement modules 421 are arranged in an array. A second translation component 120 is mounted on the base 100, and the two sets of circular runout measurement modules 421 are respectively positioned on the second translation component 120. The second translation component 120 drives the circular runout measurement modules 421 to slide and connects to the microcontroller 500. Each circular runout measurement module 421 includes a measuring rod 422, which is equipped with a connecting seat 423. The second translation component 120 is configured as a second cylinder, which is connected to the connecting seat 423. By using two sets of circular runout measurement modules 421 and driving them to slide via the second translation component 120, the circular runout of the four segments of the shaft 600 under test can be measured, simplifying the structure and reducing production costs.

[0028] Of course, four circular runout measurement modules 421 can also be configured, with each of the four circular runout measurement modules 421 corresponding one-to-one with the four shaft segments of the shaft 600 to be measured, so as to simultaneously realize the circular runout measurement of the four shaft segments of the shaft 600 to be measured; or, only one circular runout measurement module 421 can be configured, and then the second translation component 120 can drive the circular runout measurement module 421 to move, so as to realize the circular runout measurement of the four shaft segments of the shaft 600 to be measured in sequence. Those skilled in the art can reasonably select the number of circular runout measurement modules 421 according to the actual situation, and this application does not impose any restrictions on this.

[0029] Reference Figure 4 The base 100 is equipped with a third translation component 130, and the fixed seat 310 is disposed on the third translation component 130. The third translation component 130 drives the fixed seat 310 to slide, and the third translation component 130 is connected to the microcontroller 500. The structure of the third translation component 130 is the same as that of the first translation component 110. By driving the fixed seat 310 to slide through the third translation component 130, the tip 320 can be inserted into or disengaged from the shaft holes at both ends of the shaft rod 600 to be tested. The structure is simple and the operation is convenient.

[0030] Reference Figure 5The base 100 is equipped with a fourth translation component 140, and the support mechanism 200 is disposed on the fourth translation component 140. The fourth translation component 140 drives the support mechanism 200 to slide, and the fourth translation component 140 is connected to the microcontroller 500. The structure of the fourth translation component 140 is the same as that of the first translation component 110. By providing the fourth translation component 140, the position of the support mechanism 200 can be adjusted, thereby ensuring the coaxiality of the shaft 600 to be measured and the center 320, improving the stability and reliability of the measurement. Further, the support mechanism 200 includes a support base 210 and support blocks 220. The support base 210 is disposed on the fourth translation component 140, and the support blocks 220 are symmetrically disposed at both ends of the support base 210. The support blocks 220 are provided with slots 230, and both ends of the shaft 600 to be measured are embedded in the slots 230. The slot 230 is designed as a V-groove, which can accommodate different specifications of the shaft 600 to be tested, thus expanding its applicability.

[0031] It is understandable that the support mechanism 200 is equipped with a detector 240, which is used to detect whether the support mechanism 200 has the shaft 600 to be measured. The detector 240 is connected to the first translation component 110, the second translation component 120, the third translation component 130, the first translation component 110, the rotation mechanism 300, the measuring mechanism and the microcontroller 500 respectively, so that it can be fully automated and improve measurement efficiency.

[0032] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
