DETAILED DESCRIPTION

[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0041] See also Figures 1 to 5 , which is an adjustable universal tool for caliper drag test as the best embodiment of the utility model, comprises:

[0042] The base 10 is in the shape of a long plate and serves as the base of the entire tooling;

[0043] Brake disc installation tool 20, used to install and fix the brake disc to be tested;

[0044] The driving motor 30 has an output shaft 31;

[0045] The torque sensor 40 has two output ends 41, and the two output ends 41 are respectively connected to the brake disc installation tool 20 and the output shaft 31 of the driving motor 30 for recording torque data;

[0046] The adjusting mechanism 50 includes an adjusting seat 51, a mounting seat 52 slidably disposed on the adjusting seat 51 in a direction approaching or moving away from the brake disc mounting tool 20, and an adjusting component 53 for controlling the movement of the mounting seat 52;

[0047] The caliper installation tool 60 is detachably arranged on the upper end of the adjustment seat 51, and is used to install and fix the caliper that matches the brake disc to be tested on the brake disc installation tool 20;

[0048] The driving motor 30 , the torque sensor 40 , the brake disc installation tool 20 , the caliper installation tool 60 and the adjustment mechanism 50 are collinearly arranged along the same straight line on the upper end surface of the base 10 .

[0049] Preferably, Figure 3 , 4 As shown, the torque sensor 40 has two output ends 41 at both ends, and the two output ends 41 are both transmission-connected to the coupling kit 70, and the coupling kit 70 forms docking slots 71 at both ends along its axial direction, and the output shaft 31 of the drive motor 30 is inserted into the docking slot 71 to achieve transmission connection with the torque sensor 40. Therefore, the transmission connection between the torque sensor 40 and the drive motor 30 at its axial ends and the brake disc mounting tooling 20 can be stably achieved through the coupling kit 70.

[0050] Specifically, Figure 2 , 3 As shown, an L-shaped fixing plate 80 is provided on the upper end surface of the base 10, the bottom of the fixing plate 80 is locked to the upper end surface of the base 10, and the torque sensor 40 is locked and fixed to the top of its side wall, thereby facilitating the installation and fixation of the torque sensor 40.

[0051] Preferably, Figure 2 , 3As shown in Figure 4, the brake disc installation tool 20 includes an outer set 21, a coupling 22 and a brake disc fixing sleeve 23. The coupling 22 is pivotally connected to the inner side of the outer set 21. One end of the coupling 22 forms a disc-shaped fixed end 221 and the other end forms a columnar plug-in end 222. The plug-in end 222 is inserted into the docking slot 71 of the adjacent coupling set 70 to achieve a transmission connection with the torque sensor 40. Further, the brake disc fixing sleeve 23 is sleeve-shaped, and its two ends along the axial direction respectively form a fixed disc 231 and a docking end 232. The plate 232 and the fixed plate 231 are used to fit with the brake disc to be tested and be coaxially fixed, and the docking plate 232 fits with the fixed end 221 and is coaxially transmission connected. Therefore, through the brake disc installation tool 20, it is possible to conveniently realize the installation and fixation between the brake disc to be tested and the fixed plate 231, and to realize the transmission connection with the torque sensor 40 through the plug-in shaft end 222, thereby opening up the transmission connection relationship between the brake disc to be tested, the torque sensor 40 and the drive motor 30, and realizing stable testing of the brake disc to be tested and the caliper.

[0052] Preferably, Figure 3 , 5 As shown, the adjustment seat 51 includes a bottom plate 511 and a left side plate 512 and a right side plate 513 erected on both sides of the upper end surface of the bottom plate 511, a guide rail 514 and a slide seat 515 slidably arranged along the guide rail 514 are arranged between the left side plate 512 and the right side plate 513, the mounting seat 52 is arranged on the slide seat 515, a screw rod 516 parallel to the guide rail 514 is rotatably connected between the left side plate 512 and the right side plate 513, a connecting portion 5331 (not marked in the figure) threadedly connected to the screw rod 516 is provided on the mounting seat 52, a driven gear 517 is provided at the position where the screw rod 516 passes through the left side plate 512, and the adjustment component 53 includes an active adjustment gear 531 meshing with the driven gear 517, a transmission mechanism 532 fixed on the left side plate 512 and transmission-connected to the active adjustment gear 531, and an adjustment hand wheel 533 fixed on the rotating shaft of the active adjustment gear 531.

[0053] Thus, by rotating the adjusting hand wheel 533, the active adjusting gear 531 follows the rotation, and the driven gear 517 meshing therewith drives the screw rod 516 to rotate, and the slide seat 515 drives the mounting seat 52 to move along the extension direction of the screw rod 516, thereby finally realizing the position adjustment of the caliper mounting tool 60 at the upper end of the mounting seat 52.

[0054] Preferably, Figure 5 As shown, the adjusting hand wheel 533 includes a connecting portion 5331 fixed on the rotating shaft of the active adjusting gear 531 and three adjusting rods 5332 which are columnar and extend outwardly obliquely around the circumference of the connecting portion 5331 , and the three adjusting rods 5332 are evenly distributed about the connecting portion 5331 .

[0055] Preferably, Figure 4 ,5 As shown, the transmission mechanism 532 includes a disc-shaped rotating seat 5321 and a transmission shaft 5322 rotatably connected to the rotating seat 5321 axially, the rotating seat 5321 is fixed to the side of the seat side plate close to the right side plate 513 and the transmission shaft 5322 passes through the left side plate 512 and is connected to the active adjustment gear 531, and the adjusting hand wheel 533 is fixed to the end of the transmission shaft 5322, so that the transmission shaft 5322 provides a transmission basis for the integral coaxial rotation of the active adjustment gear 531 and the adjusting hand wheel 533, so that the position of the mounting seat 52 can be controlled by the adjusting hand wheel 533.

[0056] Preferably, Figure 5 As shown, the caliper mounting fixture 60 is plate-shaped and has a pair of protruding mounting edges 61 formed on its upper end. The caliper to be tested can be locked and fixed on the mounting edges 61. A mounting plate 521 that fits the caliper mounting fixture 60 is formed on the upper end of the mounting seat 52. A plurality of first mounting holes 522 are formed on the upper end of the mounting plate 521 along the height direction. A second mounting hole 62 opposite to the first mounting hole 522 is formed through the lower end of the caliper mounting fixture 60. Therefore, through the alignment between the first mounting hole 522 and the second mounting hole 62, the mounting height of the caliper mounting fixture 60 can be adaptively adjusted according to the mounting height of the different brake discs to be tested, so as to achieve stable installation and testing of the caliper and the brake disc to be tested.

[0057] In particular, such as Figure 1 As shown, a protective plate 90 is disposed around the upper edge of the left side plate 512 , and the protective plate 90 covers and protects the active adjustment gear 531 and the driven gear 517 .

[0058] The beneficial effects of the utility model are as follows:

[0059] The utility model can adapt to calipers of different sizes and designs by introducing an adjustment mechanism 50, particularly a sliding mounting seat 52 and an adjustment assembly 53, thereby significantly improving the versatility and flexibility of tooling, reducing the time and cost of replacing fixtures, improving detection efficiency, and meeting the diverse market demands for automobile brake systems.

[0060] In addition, the present invention directly integrates the torque sensor 40 with the drive motor 30 and the brake disc installation tool 20, and realizes transmission through a precise coupling kit 70, thereby ensuring the accuracy and real-time recording of torque data, and facilitating accurate evaluation of the drag performance of the caliper.

[0061] In addition, the present invention adopts an adjustment method combining a screw rod 516 and a driven gear 517. By adjusting the hand wheel 533, the position of the mounting seat 52 can be adjusted conveniently and quickly, thereby achieving precise positioning of the pressure point applied to the caliper. It is not only easy to operate, but also has a wide adjustment range, thereby improving the accuracy of the test and work efficiency.

[0062] In addition, the combined design of the new caliper mounting tool 60 and the adjustment seat 51 ensures the stable installation of the caliper during the test. The design of the protruding mounting edge 61 and the corresponding mounting plate 521, combined with the multi-point mounting holes, enhances the installation stability and repeatable positioning accuracy, ensuring the safe conduct of the test.

[0063] In addition, the modular design of the entire tooling structure in the present invention facilitates maintenance and replacement of parts. The innovative design of the adjustment hand wheel 533 (such as the three adjustment rods 5332 are evenly distributed) simplifies the operation process and reduces the difficulty of operation, so that non-professionals can also quickly get started.

[0064] In summary, the universal tooling for adjustable caliper drag testing of the utility model improves the versatility, accuracy and efficiency of detection through its unique design, and effectively solves the limitations of traditional testing devices.

[0065] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
