Description

Technical Field

[0001] The present invention relates to the technical field of braking equipment in the automation industry, and particularly to a short-type motor brake and its working test device. Background Art

[0002] The short-type brake for motors, especially the micro electromagnetic brake, is a supporting device designed specifically for servo motors, stepper motors, micro motors or special motors. The most remarkable feature of the short-type brake is its small size and compact structure, which enables it to easily adapt to various application scenarios with limited space. To achieve better performance, the short-type brake selects more slender and stable friction materials in its structure while ensuring the overall strength of the product. With the progress of technology, modern brake performance detection devices have achieved automation, intelligence and high efficiency, and can automatically complete various performance tests of the brake and output detailed test reports.

[0003] The following defects still exist in the prior art during use:

[0004] 1. The brake for motors in the prior art needs to be installed at the tail of the motor when connected to the motor. The motor rear cover requires an installation plane, the motor shaft center needs to be modified, the installation position of the shaft sleeve needs to be processed, and the brake air hood also needs to be lengthened. Non-professional processing personnel are unable to perform this work. In the moment of emergency braking or locking the shaft to prevent the motor from rotating when powered off, it cannot be quickly installed and used.

[0005] 2. When the performance detection device of the motor brake in the prior art detects the performance of the brake, since the detection platform is not suitable for manual contact, it is necessary to move the detected product to the detection platform through a manipulator, etc., and it is also necessary to replace the detected product through a manipulator. The overall cost of the detection equipment is relatively high, and it may cause the product to fall off; during the detection process of the product, it is also necessary to adjust the position of the product to observe the braking performance of the brake from two sides. Currently, the detection platform in the technology either designs a detection camera that rotates around the workbench or realizes it by controlling the rotation of the placement table, which is relatively cumbersome and requires a large equipment cost.

[0006] In view of this, we propose a short-type motor brake and its working test device to solve the existing problems. Summary of the Invention

[0029] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] Embodiment 1

[0031] As Figure 1As shown, a short motor brake proposed by the present invention includes a motor axis 7, brake coil bodies 1 are installed on both sides of the motor axis 7, single-sided brake pads 2 are installed on the upper end of the brake coil body 1, and hexagon socket screws 3 are installed on the single-sided brake pads 2. The brake coil body 1 and the single-sided brake pads 2 are fixed on both sides of the motor axis 7 by the hexagon socket screws 3, the single-sided brake pads 2 are connected to the brake blades 4, the middle of the brake blades 4 are connected to the motor axis 7, a dish-shaped spring piece 5 and a flat gasket 6 are arranged between the brake blades 4 and the motor axis 7, an adjusting screw 9 is installed on the brake blades 4, and fixing screws 8 are arranged on both sides of the adjusting screws 9, the brake blades 4 are fixedly installed on the motor axis 7 by the adjusting screws 9 and the fixing screws 8, a motor hood 10 is installed on one side of the motor, and the brake coil body 1 and the brake blades 4 are both located in the motor hood 10.

[0032] It includes from left to right a brake coil body 1, a single-sided brake pad 2, a dish-shaped spring piece 5, a flat gasket 6, a brake blade 4, an adjustment screw 9 and a fixing screw 8 of the adjustment screw 9, which relies on the brake spring of the coil body to compress the single-sided brake pad 2 and the brake blade 4, so that the single-sided brake pad 2 and the brake blade 4 generate friction. The inner side of the brake coil body 1 has three through screw holes, which are fixed and positioned with three hexagon socket screws 3 to the rear cover of the motor. The position and direction of the single-sided brake pad 2 are limited by the head of the hexagon socket screw 3 that fixes the coil body. The dish-shaped spring piece 5 and the flat gasket 6 cooperate to support the brake blade 4 to ensure that the brake blade 4 will not indirectly cause a braking effect due to the forward and backward sliding of the motor axis 7. The adjustment screw 9 has a screw to limit the brake blade 4 and the single-sided brake pad 2 to adjust the brake clearance. The fixing screw 8 of the adjustment screw 9 is used to fix the adjustment screw 9 so that it will not affect the braking performance due to loosening and displacement during long-term operation.

[0033] Further, the single-sided brake pad 2 is composed of an armature plate and a brake pad, which kills two birds with one stone and saves space.

[0034] Furthermore, the brake blade 4 is an integrated thin blade with an inwardly concave flange, so that the overall thickness of the brake is not affected by the protrusion of the hexagon socket screw 3.

[0035] Embodiment 2

[0036] like Figures 2 - 6As shown in the figure, a working test device for a short-type motor brake proposed by the present invention includes a working test device 11. Inside the working test device 11, there is a workbench 14. On the workbench 14, there is a through groove 29. Inside the through groove 29, there is a placement table 22. Directly below the lower end of the placement table 22, there is a connecting rotating column 24. On the surface of the connecting rotating column 24, there is a side arc groove 25. Near the inner side of the lower end of the placement table 22, there is a linkage rod 31. The lower end of the linkage rod 31 is connected to a sliding block 26. At the lower end of the workbench 14, there are a driving member 37, an upper rack 35, a lower rack 36, and an auxiliary rotating mechanism 33. The upper rack 35 is installed at the lower end of the sliding block 26. The lower rack 36 and the auxiliary rotating mechanism 33 are meshed and connected. The driving member 37 is connected to a driving assembly, and the driving member 37 is meshed and connected to both the upper rack 35 and the lower rack 36;

[0037] The workbench 14 is the main platform for detecting the motor brake. Through the control of the driving member 37, the upper rack 35 moves because of the rotation of the driving member 37. The movement of the upper rack 35 drives the sliding block 26 to move. The movement of the sliding block 26 drives the placement table 22 to move. At the same time when the placement table 22 moves to the detection position on the workbench 14, the driving member 37 also controls the movement of the lower rack 36. The movement of the lower rack 36 will control the rotation of the auxiliary rotating mechanism 33. During the rotation of the auxiliary rotating mechanism 33, through the abutting relationship between the movement rod 38 and the side arc groove 25, the rotation of the connecting rotating column 24 is controlled, so that the rotating storage rack 20 connected to the center of the placement table 22 and the connecting rotating column 24 starts to rotate.

[0038] During the rotation of the driving member 37, it drives the upper rack 35 to drive the sliding block 26 to move so that the placement table 22 moves to the upper end of the workbench 14. At the same time, the driving member 37 drives the lower rack 36 to control the auxiliary rotating mechanism 33 to drive the workstations on the placement table 22 to rotate.

[0039] Furthermore, the auxiliary rotating mechanism 33 includes a mounting shaft 40 and a connecting rod 41. The mounting shaft 40 is installed inside the workbench 14. On both sides of the mounting shaft 40, there are connecting rods 41. A ring member 39 is connected to the connecting rods 41. On one side of the ring member 39, there is a fixed movement rod 38. Near the rear end of the auxiliary rotating mechanism 33, there is a movement gear 23. The movement gear 23 is meshed and installed with the lower rack 36.

[0040] The driving member 37 drives the lower rack 36 to move. During the movement of the lower rack 36, the moving gear 23 will rotate accordingly. And during the rotation of the moving gear 23, the entire auxiliary rotating mechanism 33 rotates. Due to the abutting relationship between the moving rod 38 and the side arc groove 25, during the abutting movement of the moving rod 38 and the side arc groove 25, the moving rod 38 controls the connecting rotating column 24 to rotate to a certain extent, so as to change the working station direction on the placement table 22. After the moving rod 38 leaves the side arc groove, the connecting rotating column 24 stops moving, thus leaving sufficient inspection time for the inspected products on the placement table 22.

[0041] Further, a sliding groove 28 is provided inside the workbench 14, the sliding block 26 is installed in the sliding groove 28, and a spring member 34 is provided on one side of the sliding groove 28 close to the inside.

[0042] After the sliding block 26 is driven by the upper rack 35 to move to one end, it will no longer move. Because it is necessary to maintain the meshing relationship between the upper rack 35 and the driving member 37, after the placement table 22 moves upward, the sliding block 26 will move back and forth to a certain extent. Through the contact between the spring member 34 and the sliding block 26, the upper rack 35 is under the action of the spring member 34 and the driving member 37, so as to keep the upper rack 35 in meshing with the driving member 37 and avoid the failure of smooth reset.

[0043] Further, a positioning rod 32 is installed downward inside the workbench 14 near the through groove 29. The lower end of the positioning rod 32 is fixedly connected to the sliding groove 28, and an inspection product replacement window 27 is provided on the back of the workbench 14.

[0044] After the hinge member 30 at the upper end of the linkage rod 31 moves to be close to the positioning rod 32, the hinge member 30 slides upward along the positioning rod 32, thereby driving the placement table 22 to move upward. The inspection product replacement window 27 is installed at the rear end to replace and fix the inspection products on the placement table 22.

[0045] Further, a rotating placement rack 20 connected to the connecting rotating column 24 is provided at the center of the placement table 22, and positioning grooves 21 are provided on both sides of the placement table 22.

[0046] The rotating placement rack 20, as a placement platform following the movement of the connecting rotating column 24, can be used to change the inspection surface of the platform, and the positioning grooves 21 are used to fix the position of the placement table 22.

[0047] Further, clamping control members 16 are provided on both sides of the upper end of the workbench 14. Clamping rods 17 are installed on the clamping control members 16 facing the placement table 22. The clamping rods 17 are connected with clamping blocks 15, and the clamping blocks 15 extend into the positioning grooves 21.

[0048] The clamping control member 16 controls the movement of the clamping rod 17, thereby fixing the position of the clamping block 15 with respect to the placement table 22. Since it is necessary to maintain the meshing relationship between the upper rack 35 and the driving member 37, after the placement table 22 moves to the specified detection position, the linkage rod 31 and the sliding block 26 will exhibit a certain reciprocating movement, which may affect the instability of the placement table 22. Therefore, the clamping control member 16 can control the placement table 22 to make it more stable.

[0049] Further, a vision detection device 19 is installed inside the working test device 11 on the side far from the placement table 22, and multiple groups of detection camera heads 18 are installed on the side of the vision detection device 19 close to the placement table 22.

[0050] The vision detection device 19 can control the extension of the detection camera heads 18, and multiple groups of detection camera heads 18 can comprehensively detect the working performance of the motor brake.

[0051] Further, a transparent glass 12 is provided at the front end of the working test device 11, a telescopic support foot 13 is provided at the bottom of the working test device 11, and a detection product replacement window 27 is provided at the rear end of the working test device 11.

[0052] The transparent glass 12 is used to facilitate the staff to observe the detection situation. The telescopic support foot 13 can control the lifting of the working test device 11. The detection product replacement window 27 is used to facilitate the staff to replace the detection product.

[0053] Further, hinge members 30 are provided at both the upper and lower ends of the linkage rod 31. The upper end of the linkage rod 31 is installed at the lower end of the placement table 22 through the hinge member 30, and the lower end of the linkage rod 31 is installed at the upper end of the sliding block 26 through the hinge member 30.

[0054] There is a certain connection space at the connection between the hinge member 30 and the upper end of the linkage rod 31. When the upper rack 35 and the driving member 37 maintain the meshing relationship and cause the movement of the linkage rod 31, it has sufficient movement space. And a limiting block is provided at the connection between the hinge member 30 and the lower end of the linkage rod 31. When the sliding block 26 resets, the linkage rod 31 can stabilize the position of the placement table 22.

[0055] The above specific embodiments are merely several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
