Description

Technical Field

[0002] As a critical braking component in mechanical equipment, brakes ensure rapid braking in the event of unexpected power outages, gas outages, or emergency shutdowns, effectively protecting the equipment and personnel. However, if the brakes fail, the equipment cannot be shut down quickly, potentially causing production accidents or even endangering lives. Therefore, to ensure their effectiveness, regular brake inspections are essential.

[0003] In the brake, it mainly relies on the contact between the brake parts and the friction plate to increase the friction force so as to pause the equipment. In the existing technology, the friction disc is usually made of metal materials, ceramic materials and organic materials. Among them, the friction plate of organic materials has the advantages of low noise and less wear on the brake parts.

[0004] However, in high temperature environments, the performance of the brake pad is easily reduced and the wear resistance is poor.

[0005] In order to fully test the performance of the composite electromagnetic brake, it is necessary to test its internal friction plate to understand the performance of the friction plate. However, the existing technical solutions cannot fully realize the monitoring of the composite brake pad when the brake is operating, so improvements are needed. Summary of the Invention

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Reference Figure 1-7 A composite electromagnetic brake detection tooling includes a driving mechanism, which is provided with a support shaft assembly 8. The driving mechanism can control the rotation data of the support shaft assembly 8 to drive the electromagnetic brake assembly 19 to operate, thereby simulating the operation of the composite plastic brake pad 194 in the electromagnetic brake assembly 19 under different working conditions, thereby improving the accuracy of the detection. A detection box assembly 7 is rotatably sleeved on the support shaft assembly 8, and an installation mechanism is provided on the detection box assembly 7. The detection components are all located in the detection box assembly 7 and can be effectively protected by the installation mechanism. It is also convenient to control the electromagnetic brake assembly 19 to operate under different temperature conditions, thereby improving the range of the simulated environment.

[0031] In this embodiment, the electromagnetic brake assembly 19 is detachably connected to the support shaft assembly 8, and the electromagnetic brake assembly 19 is provided with a mounting box 196 and a composite plastic brake pad 194; the electromagnetic brake assembly 19 can be installed on the support shaft assembly 8 as needed, and at the same time, by setting the corresponding components on the support shaft assembly 8, the range of adaptable specifications of the electromagnetic brake assembly 19 is improved, and the stable transmission of power to the electromagnetic brake assembly 19 can be fully guaranteed, so that the electromagnetic brake assembly 19 can operate stably, and the composite plastic brake pad 194 and the mounting box 196 can be made to rub against each other, simulating the operation of the electromagnetic brake assembly 19 and obtaining accurate data.

[0032] In this embodiment, a clamping mechanism is provided on the side wall at one end of the detection box assembly 7, and two clamping plates 18 are provided on the clamping mechanism. The position of the clamping plate 18 can be adjusted through the clamping mechanism, and the two clamping plates 18 respectively abut against the upper and lower ends of the installation box 196; the movement of the clamping plate 18 can achieve clamping of the installation box 196, so as to ensure that the electromagnetic brake assembly 19 is firmly installed.

[0033] In this embodiment, a friction linkage component 15 is passed through the clamping plate 18 at the upper end, and the lower end of the friction linkage component 15 passes through the clamping plate 18 and interferes with the upper end of the composite plastic brake pad 194; a carrier 16 is installed on the upper end of the clamping plate 18, and a double gear component 12 is rotatably sleeved on one side of the carrier 16. The double gear component 12 and the friction linkage component 15 are meshed, and a lifting sensor component 14 is meshed on one side of the double gear component 12. The lifting sensor component 14 is slidably installed on the upper end of the clamping plate 18, and a detection sensing component 13 is installed on one side of the upper end of the carrier 16. The detection sensing component 13 corresponds to the lifting sensor component 14; a plurality of teeth are provided on one side of the friction linkage component 15 that is meshed with the double gear component 12, so that the friction linkage component 15 can be lifted and lowered by rotating the double gear component 12, and the friction linkage component The lower end of 15 will come into contact with the composite plastic brake pad 194. When the composite plastic brake pad 194 and the mounting box 196 perform the braking operation, the composite plastic brake pad 194 will generate heat by friction with the mounting box 196. At this time, the composite plastic brake pad 194 will expand due to the heat, become damaged, and its hardness changes. The tension spring 17 makes the conflict linkage assembly 15 come into contact with the outside of the composite plastic brake pad 194. All changes in the composite plastic brake pad 194 cause the conflict linkage assembly 15 to move. The dual gear assembly 12 is composed of a large gear and a small gear arranged coaxially. The conflict linkage assembly 15 is meshed with the small gear. When the angular velocity of the large gear and the small gear is the same, the large gear moves more in the linear velocity. This will make the lifting range of the lifting sensor assembly 14 larger, which is convenient for detection by the detection sensing assembly 13 to understand the condition of the composite plastic brake pad 194.

[0034] A temperature detection component is provided through the clamping plate 18 at the lower end. The temperature detection component passes through the clamping plate 18 at the lower end and contacts the lower end of the composite plastic brake pad 194. The temperature detection component can detect the temperature change in the composite plastic brake pad 194.

[0035] A tension spring component 17 is fixed on one side of the temperature detection component and the friction linkage component 15. The two tension spring components 17 are respectively fixedly connected to the two clamping plates 18. The action of the tension spring component 17 can fully ensure that the temperature detection component and the friction linkage component 15 are in friction with the outside of the composite plastic brake pad 194, thereby ensuring the quality of detection.

The ends of the two clamping plates 18 away from the electromagnetic brake assembly 19 are slidably mounted on the side walls inside the detection box assembly 7; the angle between the two oblique rods 11 can be adjusted by the extension and contraction of the piston rod on the hydraulic telescopic assembly 5. When the angle between the two oblique rods 11 changes, the distance between the two clamping plates 18 can be changed. For example, when the angle between the two oblique rods 11 gradually increases, the distance between the two clamping plates 18 will increase. When the angle between the two oblique rods 11 decreases, the distance between the two clamping plates 18 will decrease, which helps to clamp the electromagnetic brake assembly 19.
