[0003] After the production of brake shoes is completed, their thickness needs to be tested. Products that do not meet the thickness standards need to be picked out to ensure product quality. The patent document with the prior art publication number CN219455034U provides a brake shoe thickness detection device. The device clamps the brake pad through a first measuring rod and a second measuring rod to obtain the thickness of the brake pad. Because the cross-sections of the support rod, the first measuring rod and the second measuring rod are all circular, and there is line contact between them and the brake pad, it can solve the influence of the curvature of the brake pad and improve the accuracy of thickness detection.

[0004] This device requires the brake pad to be placed on a first measuring rod and a support rod during testing. The second measuring rod then moves vertically to the first measuring rod to clamp the brake pad and perform the measurement. This cumbersome operation results in low testing efficiency, making it unsuitable for use in industrial production environments. Therefore, a brake shoe thickness testing device is urgently needed to address this issue. Utility Model Content

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a brake shoe thickness detection device, which includes a conveying platform 1, a detection unit 2 is installed at one end of the conveying platform 1, the detection unit 2 includes a control panel 201 and a distance sensor 202 connected thereto, a storage box 3 is installed at the other end of the conveying platform 1, a discharge port is opened at one end of the storage box 3, and a discharge mechanism 4 is installed in the storage box 3.

[0027] The discharging mechanism 4 includes a push plate 401, one side of which is elastically connected to two sliders 402, and the sliders 402 are threaded with a screw 404, one end of the screw 404 is transmission-connected to a driven gear 408, and one side of the driven gear 408 is meshed with an arc-shaped rack 409, and the arc-shaped rack 409 is transmission-connected to the conveying platform 1.

[0028] In the above technical solution, the conveyor platform 1 is composed of a support frame, a synchronous belt, a synchronous roller and a drive system. The brake shoe to be tested is placed between the storage box 3 and the push plate 401. When the synchronous roller rotates, it drives the arc rack 409 to rotate. The arc rack 409 intermittently contacts the driven gear, so that the screw 404 rotates intermittently. The screw 404 cooperates with the slider 402 to drive the push plate 401 to move intermittently, so that the push plate 401 can push the brake shoe to move each time it moves, so that the brake shoe near the discharge port falls down onto the synchronous belt. When the synchronous belt drives the brake shoe to move below the distance sensor 202, the distance sensor 202 detects the thickness of the brake shoe.

[0029] The detection unit 2 further includes a fixing frame 203 fixedly mounted on one end of the conveying platform 1 , and the control panel 201 and the distance sensor 202 are both connected to the fixing frame 203 .

[0030] In the above technical solution, the detection end of the distance sensor 202 is facing one side of the synchronous belt. When the brake shoe does not pass under the distance sensor 202, the detection value of the distance sensor 202 is the distance from the detection end to the upper surface of the synchronous belt. When the brake shoe passes, the detection value of the distance sensor 202 is the distance from the detection end to the upper surface of the brake shoe. The difference between the two distances is the thickness value of the brake shoe.

[0031] It is understandable that a control module and a preset algorithm are set in the control panel 201, and a display screen is provided on the control panel 201. When the brake shoe is detected by the distance sensor 202, its thickness value can be displayed on the display screen.

[0032] A material guide plate 301 is fixedly connected to one side of the material storage box 3, and the material guide plate 301 is arranged on one side of the material discharge port.

[0033] In the above technical solution, the guide plate 301 is arranged at an angle, so that the brake shoe pushed away from the discharge port can slide onto the synchronous belt through the guide plate 301, avoiding damage during the detection process.

[0034] The arc-shaped rack 409 is fixedly connected to the rotating plate 410 , and the rotating plate 410 is coaxially connected to the synchronous roller of the conveying platform 1 .

[0035] In the above technical solution, the driven gear 408 is connected to the screw 404 through a steering gear. Whenever the arc-shaped rack 409 contacts the driven gear 408, the driven gear 408 can be driven to rotate a certain number of circles, thereby driving the screw 404 to rotate. The screw 404 cooperates with the slider 402 to drive the push plate 401 to move a certain distance.

[0036] During use, the brake shoe to be tested is placed between the push plate 401 and the storage box 3, the driving system drives the synchronous belt to rotate, and a synchronous roller drives the rotating disk 410 to rotate. Whenever the arc rack 409 contacts the driven gear 408, the driven gear 408 can be driven to rotate a certain number of circles, so that the screw 404 cooperates with the slider 402 to drive the push plate 401 to move a certain distance, thereby pushing the brake shoe close to the discharge port side to the guide plate 301 and slide it onto the synchronous belt. The synchronous belt drives the detection unit 2 on the brake shoe to move. When the brake shoe passes under the distance sensor 202, the thickness of the brake shoe can be detected and displayed on the control panel 201.

[0037] Example 2

[0038] Reference Figure 4 , which is the second embodiment of the present utility model. This embodiment is different from the first embodiment in that: a threaded groove 403 adapted to the screw 404 is provided on one side of the slider 402, and a pull rod 405 is fixedly connected to the other side. The pull rod 405 is slidably connected to the push plate 401, and a spring 406 is sleeved on the pull rod 405, and both ends of the spring 406 are respectively connected and fixed to the pull rod 405 and the push plate 401.

[0039] In the above technical solution, the elastic force of the spring 406 is used to drive the thread groove 403 of the slider 402 to fit tightly against the screw 404, so that the screw 404 can drive the slider 402 to move horizontally. When the pull rod 405 is pulled to move the slider 402 away from the screw 404, the slider 404 is not limited by the screw 404. At this time, the push plate 401 can be driven to slide quickly, so that it can be moved to the side away from the discharge port.

[0040] The screw rod 404 is rotationally connected to the material storage box 3 , and the slider 1 402 is slidably connected to the slider 2 407 . The slider 2 407 is sleeved on the screw rod 404 and slidably connected to the material storage box 3 .

[0041] In the above technical solution, the slider 1 402 is limited by the sliding cooperation between the slider 2 407 and the storage box 3, and the push plate 401 can slide straight.

[0042] The remaining structures are the same as those of Example 1.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
