Description

Technical Field

[0001] The utility model relates to the field of electromagnetic brake detection, in particular to an electromagnetic brake detection platform. Background Art

[0002] Electromagnetic brake is a connector that transmits the torque of the active side to the passive side. It can be freely connected, disconnected or braked as needed. It is an ideal automatic actuator in modern industry. It mainly plays the role of transmitting power and controlling movement in mechanical transmission systems. It has the advantages of compact structure, simple operation, sensitive response, long life, reliable use, and easy remote control. The gap of the electromagnetic brake refers to the distance between the brake clutch plates. The appropriate gap is the guarantee for the normal operation of the electromagnetic brake. Too large or too small a gap will affect the braking performance and even cause the brake to fail. Therefore, the gap of the electromagnetic brake should be detected to ensure normal operation. However, at present, most of the gaps are measured manually using a measuring ruler, which is inefficient and inaccurate.

[0003] Chinese patent document CN220083895U discloses a fault detection device for an electromagnetic brake. By setting a movable block, a No. 1 plate and a No. 3 plate, the detection device is convenient for starting the motor to push the movable block to move backwards during use. The movable block drives the No. 2 plate and the No. 4 plate to move backwards, while the spring drives the No. 1 plate and the No. 3 plate to move backwards. Then, the position state of the No. 1 plate, the No. 2 plate, the No. 3 plate and the No. 4 plate in the brake gap is observed, and it is convenient and clear to determine whether the size of the brake gap meets the standard, thereby reducing the burden of manual measurement and greatly improving the measurement accuracy and efficiency. The utility model proposes a detection platform for an electromagnetic brake with other structures. Utility Model Content

[0029] like Figure 1-2 As shown, an electromagnetic brake detection platform includes an operating platform 1 and a limiting device 4 and a placing table 10 arranged on the operating platform 1. The limiting device 4 includes a bidirectional threaded rod 2, a slider 5, a limiting plate 7 and a rubber wheel 8. The bidirectional threaded rod 2 can be rotatably arranged in a groove opened in the operating platform 1. The bidirectional threaded rod 2 passes through the side wall of the operating platform 1 and is provided with a hand wheel 3. Two sliders 5 are respectively threadedly connected to two threaded sections of the bidirectional threaded rod 2. When the bidirectional threaded rod 2 rotates, the two sliders 5 move in the same direction or in opposite directions; the two sliders 5 match the grooves in the operating platform 1, and the grooves make the sliders The block 5 cannot rotate; a connecting seat 6 is provided on the top of the slider 5, and a long hole 9 for the connecting seat 6 to slide is provided at the corresponding position on the top of the operating platform 1. A limit plate 7 is provided on the top of the connecting seat 6, and a plurality of rubber wheels 8 are provided at the lower end of the limit plate 7 for horizontal rotation. A mounting groove is provided on the surface of the limit plate 7, and rubber wheels 8 are installed in the mounting groove for horizontal rotation; the placing table 10 can be rotatably set on the base 15, and the base 15 is fixedly set in the groove in the operating platform 1, and the bidirectional threaded rod 2 passes through the base 15. The part of the bidirectional threaded rod 2 passing through the base 15 is a smooth section, and the bidirectional threaded rod 2 can rotate relative to the base 15. A spacing measuring instrument 19 and a display screen 20 for displaying measurement data are provided on the upper surface of the operating platform 1 in front of the placing table 10.

[0030] It is worth noting that the electromagnetic brake is limited and fixed by the limit device 4, and the electromagnetic brake is preliminarily positioned by the placement table 10, which is convenient for the limit device 4 to limit and fix the electromagnetic brake, and can rotate with the electromagnetic brake at the same time. The limit device 4 is driven to slide by the bidirectional threaded rod 2, and the two sets of limit devices 4 can be moved away or close at the same time, and the bidirectional threaded rod 2 is driven to rotate by the hand wheel 5. Specifically, the limit plate 7 is driven to move by the slider 5, and the groove makes the slider 5 not rotate with the bidirectional threaded rod 2 when it rotates, but produces left and right displacement. The limit plate 7 is set to produce a limit effect on the electromagnetic brake, and the rubber wheel 8 is set to reduce the friction when the electromagnetic brake rotates. Further, the gap of the electromagnetic brake is measured by the spacing measuring instrument 19, and the data measured by the spacing measuring instrument 19 is displayed by the display screen 20, and the data that does not meet the standard is marked in red.

[0031] In some feasible embodiments, the limiting plate 7 is an arc-shaped structure, and its arc-shaped opening faces the placement platform 10 .

[0032] In some feasible embodiments, the placement table 10 is a circular structure, and a positioning shaft 12 is coaxially disposed on the top thereof. The electromagnetic brake is sleeved on the positioning shaft 12 to play a positioning role, so that the electromagnetic brake is located at the center of the placement table 10, which is convenient for the limiting device 4 to limit and fix.

[0033] In some feasible embodiments, a sleeve 13 is coaxially disposed at the bottom of the placement table 10, a support shaft 14 is disposed at the center of the top of the base 15, and the sleeve 13 is rotatably connected to the support shaft 14 through a bearing. The arrangement of the sleeve 13 and the support shaft 14 allows the placement table 10 to rotate freely.

[0034] In some feasible embodiments, an anti-skid layer 11 is disposed on the upper surface of the placement platform 10. The anti-skid layer 11 prevents the electromagnetic brake from sliding against the placement platform 10.

[0035] In some feasible embodiments, a second slide groove 17 is provided at the connection between the operating platform 1 and the placement table 10, a first slide groove 16 is provided at the edge of the placement table 10, and the sizes of the first slide groove 16 and the second slide groove 17 match, and a moving block 18 is slidably provided in the second slide groove 17, and the moving block 18 can slide in the first slide groove 16 and the second slide groove 17. When the moving block 18 is located in the second slide groove 17, the placement table 10 can rotate freely, and when the moving block 18 moves toward the first slide groove 16 and is located in the first slide groove 16 and the second slide groove 17 at the same time, the placement table 10 cannot be transferred.

[0036] In some feasible embodiments, the upper surface of the operating platform 1 is located behind the placement table 10 and is provided with a thickness gauge 21 through a mounting seat. When adjusting the gap of the electromagnetic brake, the thickness gauge 21 can limit the gap to facilitate the adjustment operation. Specifically, first select a suitable thickness gauge 21, then insert the selected thickness gauge 21 into the gap of the electromagnetic brake, and then adjust the hollow bolt. It should be emphasized that the thickness gauge 21 needs to be inserted into the gap from different positions for multiple times to ensure that the gap of the electromagnetic brake can be adjusted in place.

[0037] In some feasible embodiments, a hole is opened in the base 15 for the smooth section of the bidirectional threaded rod 2 to pass through, and the bidirectional threaded rod 2 can rotate relative to the base 15, so that the base 15 does not restrict the rotation of the bidirectional threaded rod 2.

[0038] In some feasible embodiments, the placement table 10 is disposed in the operating platform 1 , and the top thereof is flush with the upper surface of the operating platform 1 .

[0039] When in use, the electromagnetic brake is sleeved on the positioning shaft 12, placed on the placement table 10, the moving block 18 is moved so that it is located in the second slide groove 17, the hand wheel 3 is turned to drive the bidirectional threaded rod 2 to rotate, and then the limit device 4 is driven to approach the electromagnetic brake until the two limit devices 4 clamp the electromagnetic brake, and then the spacing measuring instrument 19 is started, and the electromagnetic brake is slowly rotated, so that the spacing measuring instrument 19 measures the gap of the electromagnetic brake for one week. If the measurement result meets the standard, the hand wheel 3 is rotated in the opposite direction to make the limit device 4 move outward at the same time, and the next electromagnetic brake to be measured is replaced; if the measurement result does not meet the standard, the moving block 18 is pushed to make the placement table 10 unable to rotate, and then the installation bolts are evenly loosened with a hexagonal wrench, and then the appropriate thickness gauge 21 is inserted into the gap, and then the hollow screw is adjusted. The thickness gauge 21 needs to be inserted into the gap from different positions for multiple times for adjustment. After the adjustment is completed, the installation bolts are tightened, and then the gap is detected for one week. If it is unqualified, repeat the above steps and readjust until the gaps at all locations of the electromagnetic brake meet the standard.
