[0041] like Figure 2 As shown in the embodiment of this application, the torsion beam testing device is used to perform dimensional testing on a torsion beam 700. The testing device includes a testing table 100, a positioning module 200, and a testing module 500. The positioning module 200 and the testing module 500 are both disposed on the table surface of the testing table 100, so that the torsion beam 700 can be dimensionally tested on the testing table 100. Figure 1 As shown, the torsion beam 700 includes two symmetrically distributed longitudinal arms 710 and a connecting arm 720 connecting the two longitudinal arms 710. The positioning module 200 is engaged with the longitudinal arms 710 to pre-position the torsion beam 700 as a whole, so as to facilitate subsequent dimensional inspection. The detection module 500 can slide relative to the torsion beam 700 so that the detection module 500 can slide to correspond to the detection position of the torsion beam 700, so that the dimensional inspection of the torsion beam 700 can be realized through the detection module 500, thereby improving the efficiency and accuracy of the dimensional inspection of the torsion beam 700.
[0042] like Figure 6 As shown, each longitudinal arm 710 is provided with a positioning hole 711, and the positioning hole 711 is provided on the bottom surface of the longitudinal arm 710. The positioning hole 711 corresponds to the longitudinal arm 710 one by one, so that the torsion beam 700 can be positioned and engaged with the positioning module 200 through the positioning hole 711.
[0043] like Figures 3-4 As shown, the positioning module 200 includes a positioning module body, a positioning pin 202, and a first driving member 201. The positioning module body is fixedly connected to the table surface of the detection table 100. The positioning pin 202 is movably connected to the top of the positioning module body and can be engaged with the positioning hole 711. The fixed end of the first driving member 201 is fixedly connected to the inside of the positioning module body, and the driving end of the first driving member 201 is connected to the positioning pin 202 for transmission, so that the first driving member 201 can drive the positioning pin 202 to reciprocate linearly along the axial direction of the first driving member 201, so that the positioning pin 202 can be engaged with the positioning hole 711 to achieve pre-positioning of the torsion beam 700.
[0044] To enhance the fixing effect on the torsion beam 700, each longitudinal arm 711 is equipped with at least two positioning surfaces, such as... Figure 3 As shown, the detection device provided in this application embodiment also includes a clamping module 300. The clamping module 300 is used to clamp and position the torsion beam 700 with the positioning surface. There are at least four clamping modules 300, and each clamping module 300 corresponds to a positioning surface to improve the fixing effect of the torsion beam 700.
[0045] In some embodiments, such as Figure 6 As shown, the bottom surface of each longitudinal arm 711 is provided with a first positioning surface 712 and a second positioning surface 713, so as to pre-position with the clamping module 300 through the positioning surface, so that the clamping module 300 can relatively fix the torsion beam 700, thereby improving the stability of the subsequent detection process and further improving the detection accuracy.
[0046] like Figure 5 As shown, the clamping module 300 includes a positioning platform 301, a second driving component 302, and a clamping block 303. The positioning platform 301 is fixedly connected to the surface of the detection table 100, and its position corresponds one-to-one with the first positioning surface 712 and the second positioning surface 713, allowing the first and second positioning surfaces 712 and 713 to be placed on the positioning platform 301 and engage with it to achieve pre-positioning. The second driving component 302 is fixedly connected to... The testing platform 100 has a platform surface, and the second driving member 302 is connected to a clamping block 303 so that the second driving member 302 can drive the clamping block 303 to reciprocate linearly along the axis of the second driving member 302, so that the clamping block 303 can abut against the opposite side of the positioning surface. Through the relative abutment force of the positioning platform 301 and the clamping block 303 on the longitudinal arm 710, the torsion beam 700 is relatively fixed, improving the stability of the torsion beam 700 fixation and thus improving the subsequent testing accuracy.
[0047] In some embodiments, the first driving member 201 and the second driving member 302 can both be driving devices capable of linear drive, such as pneumatic drive, hydraulic drive, and electric drive. This application embodiment does not limit this.
[0048] like Figure 1 As shown, each longitudinal arm 710 is equipped with a first detection position 714 and a second detection position 715. There is one first detection position 714 and one second detection position 715 on one longitudinal arm 710, and two first detection positions 714 and two second detection positions 715 on one torsion beam 700. In this way, the detection module 500 is matched with each detection position one by one to detect the distance between the detection positions, so as to realize the size detection of the torsion beam 700, improve the detection efficiency and detection accuracy.
[0049] like Figures 2-3 As shown, the detection device provided in this application embodiment also includes a moving module 400, and a detection module 500 is disposed on the moving module 400 so that the moving module 400 can drive the detection module 500 to move so that the detection module 500 can correspond to the first detection position 714 and the second detection position 715 of the torsion beam 700 respectively.
[0050] like Figure 8 As shown, the detection module 500 includes a first detection component 510 and a second detection component 520. There are two first detection components 510, which correspond one-to-one with the first detection bit 714; there are two second detection components 520, which correspond one-to-one with the second detection bit 715.
[0051] like Figures 9-10 As shown, the first detection component 510 includes a first probe 511, which can abut and sense the first detection position 714; the second detection component 520 includes a second probe 521, which can abut and sense the second detection position 715. In this way, through the sensing detection of the first probe 511 and the second probe 521, the size detection between the first detection position 714 and the second detection position 715 is realized, thereby realizing the size detection of the torsion beam 700 and improving the detection accuracy of the torsion beam 700.
[0052] like Figure 3 As shown, in order to drive the first detection component 510 and the second detection component 520 respectively, the moving module 400 includes a first moving component 410 and a second moving component 420.
[0053] The first moving component 410 is fixedly connected to the table surface of the detection stage 100, and the first detection component 510 is slidably engaged with the first moving component 410. Specifically, the first moving component 410 may include a sliding rail and a moving stage that slide relative to each other. By placing the first detection component 510 on the moving stage, the first moving component 410 drives the first detection component 510 to move through the sliding engagement between the moving stage and the sliding rail, so that the first detection component 510 can drive the first probe 511 to contact and sense the first detection position 714.
[0054] like Figure 3 As shown, there are two first moving components 410, and each first moving component 410 corresponds to a first detection component 510, so that the first detection component 510 can detect the corresponding first detection position 714.
[0055] like Figure 3 and Figure 7 As shown, the second moving component 420 includes a first guide rail 421 and a second guide rail 422. The first guide rail 421 is fixedly connected to the table surface of the detection table 100. The second guide rail 422 is slidably engaged with the first guide rail 421. The second detection component 520 is slidably engaged with the second guide rail 422. The sliding direction of the first guide rail 421 and the sliding direction of the second guide rail 422 have an angle to expand the moving range of the second detection component 520, so that the second detection component 520 can be more accurately positioned with the second detection position 715.
[0056] Specifically, the second guide rail 422 may include a sliding rail and a moving stage. By placing the second detection component 520 on the moving stage and through the sliding cooperation between the moving stage and the slide rail, the second moving component 420 drives the second detection component 520 to move, so that the second detection component 520 can drive the second probe 521 to contact and sense the second detection position 715.
[0057] It should be noted that the angle between the first guide rail 421 and the second guide rail 422 can be acute, right, or obtuse. In order to further improve the accuracy of the second detection position 715, the first guide rail 421 and the second guide rail 422 are vertically distributed in this embodiment of the application, so as to further improve the movement range of the second detection component 520 driving the second probe 521.
[0058] like Figure 2As shown, the detection device provided in this application embodiment also includes a control module 600. The positioning module 200, the clamping module 300, the moving module 400, and the detection module 500 are all electrically connected to the control module 600, so that the control module 600 can control the movement of the first driving member 201, the second driving member 302, the first moving component 410, and the second moving component 420. The control module 600 can acquire the size data sensed by the first probe 511 and the second probe 521. In practice, the data can be displayed through a display device to realize the size detection of the torsion beam 700.
[0059] When the torsion beam testing device provided in this embodiment is in operation, the torsion beam 700 is first placed on the testing table 100. Positioning is achieved by the positioning holes 711 and positioning pins 202 in the longitudinal arm 710, thus pre-positioning the torsion beam 700 as a whole. This ensures that the first positioning surface 712 and the second positioning surface 713 are both located on the positioning platform 301, keeping the torsion beam 700 stable. Then, the second driving component 302 is driven to move the clamping blocks 303 towards the longitudinal arm 710 until all clamping blocks 303 abut against the side of the longitudinal arm 710 corresponding to the positioning surfaces, thereby relatively fixing the torsion beam 700 as a whole. Afterwards, the first moving component 410 and the second moving component 420 respectively drive the first testing group... The first probe 510 and the second detection component 520 move so that the first probe 511 and the second probe 521 contact and sense with the first detection position 714 and the second detection position 715 respectively, so as to detect the size data of the torsion beam 700 through the first probe 511 and the second probe 521 and display it through the display device to obtain the size data of the torsion beam 700. Then, the second driving component 302 is driven to move the clamping block 303 away from the longitudinal arm 710, and the first driving component 201 is driven to lower the positioning pin 202 and disengage it from the positioning hole 711, so that the torsion beam 700 can be removed from the detection device, completing the size detection. By performing size detection on the torsion beam 700 through each module, the detection efficiency and detection accuracy of the torsion beam 700 are improved.
[0060] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
