Description

Technical Field

[0001] This utility model relates to the technical field of brake unit calibration devices, and in particular to a brake unit torque calibration workstation. Background Technology

[0002] The braking unit is a key component of a locomotive, enabling it to decelerate and stop. The fasteners of the braking unit are a crucial part of the system. Loose fasteners significantly impact the braking unit's performance; therefore, torque checks are necessary for all fasteners in the braking unit to ensure safe locomotive operation.

[0003] Traditionally, torque verification of brake units is done manually using tools such as manual torque wrenches. This process requires using cranes to flip and move the brake units, which poses safety hazards, is inefficient, and consumes a lot of manpower. For fasteners that require visual inspection, manual operation may involve a lack of concentration and uncertainty. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a braking unit torque verification workstation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A braking unit torque verification workstation is provided, characterized in that it includes a robot, an image acquisition device, a torque verification device, an anti-loosening line marking device, a bit storage table, and a material tray; The material tray is placed at the entrance of the verification workstation. The material tray, the image acquisition device, the torque verification device, the bit storage table, and the anti-loosening line marking device are arranged in sequence around the robot. The robot's gripping end is fixedly equipped with a braking unit clamp and a bit clamp. The torque verification device is equipped with a tightening shaft for mounting the bit and providing the set torque.

[0006] Compared with the prior art, the present invention has the following technical effects: The brake unit torque verification workstation in this application uses a brake unit gripper mounted on a robot to hold brake units and move them between a material pallet, an image acquisition device, a torque verification device, a bit storage table, and an anti-loosening line marking device. This allows for verification operations of the brake units at different verification stations. The bit gripper allows for the replacement of bits used for torque verification, and, in conjunction with tightening shafts providing different torques, the torque of the brake unit can be verified. This workstation improves the efficiency and accuracy of brake unit verification. Attached Figure Description

The material tray is placed at the entrance of the verification workstation. The material tray, the image acquisition device 20, the torque verification device 30, the bit storage table 50, and the anti-loosening line marking device 40 are arranged in sequence around the robot 10. The robot 10 is fixedly equipped with a braking unit clamp and a bit clamp. The torque verification device 30 is equipped with a tightening shaft 32 for mounting the bit and providing the set torque.

[0013] In practice: The braking unit torque verification workstation is equipped with a robot 10, and an image acquisition device 20, a torque verification device 30, a bit storage table 50, a marking device, and a manual operation table arranged around the robot 10. All of the above devices are placed in a workroom with an entrance. The robot 10 is equipped with a braking unit clamp and a bit clamp, which can respectively clamp the braking unit and the bit for verification.

[0014] The image acquisition device 20 includes a mounting frame 21 and a camera. The camera includes a first image acquisition device 22 and a second image acquisition device 23, which are respectively mounted on the top and middle of the mounting frame 21. Image acquisition is completed by the robot 10 driving the movement of the braking unit. The process involves two steps: first, locating and identifying the fasteners on the braking unit; and second, for the fasteners on the braking unit that require image acquisition, moving the braking unit to the image acquisition station, acquiring images, and then identifying and analyzing whether the fasteners are qualified according to standards.

[0015] The torque verification device 30 includes a tightening shaft 32 and a tightening column 31. It can quickly install and remove the bit and change the torque value in real time to verify the torque of the fasteners. Multiple torque verification devices 30 are used; in this embodiment, four torque verification devices 30 are used to verify the torque of all fasteners at the bottom and top of the braking unit. The tightening shaft 32 employs various installation methods to accommodate fasteners in different orientations and positions. Based on the verification position, it can be divided into a bottom torque verification device 30 and a top torque verification device 30. The tightening shaft 32 of the bottom torque verification device 30 is installed on the top of the tightening column 31, with the test end of the tightening shaft 32 facing upwards. The top torque verification device 30 also includes a mounting base 33, which is installed on the top of the tightening column 31. The tightening shaft 32 is installed on the mounting base 33, with the test end of the tightening shaft 32 facing downwards. In this embodiment, three bottom torque verification devices 30 are used, and one top torque verification device 30 is used.

[0016] Anti-loosening line marking device 40: The robot 10 drives the braking unit to the anti-loosening line marking device 40 to mark the fasteners of the braking unit. The marking of each fastener is completed by the rotation of the robot 10. The anti-loosening line marking device 40 includes a mounting bracket 41, a first marking device 42 and a second marking device 43. The first marking device 42 and the second marking device 43 are respectively installed on the top and middle of the mounting bracket 41.

[0017] Braking unit clamp: In one embodiment, a first clamping component 100 and a second clamping component 200 are fixedly connected by a connector 300. The braking unit clamp clamps and fixes the mounting plate of the brake caliper and the brake pad support, respectively. Any other clamping device capable of gripping and moving the braking unit can also be used. The quick-connect coupling 400 can be fixedly connected to either the first clamping component 100 or the second clamping component 200. In this embodiment, the quick-connect coupling 400 is fixedly connected to the second clamping component 200.

[0018] The first clamping component 100 includes a first mounting base 110, a telescopic device 130, and a support claw 120. The telescopic device 130 is fixedly connected to the first mounting base 110. The telescopic device 130 is preferably a telescopic cylinder, using pneumatic, electric, or hydraulic power. The telescopic cylinder is a double-headed telescopic cylinder, or a combination of two or four telescopic cylinders. The output ends of the telescopic cylinders are symmetrically arranged on both sides of the first mounting base 110. The support claw 120 is fixedly connected to the output ends. The telescopic device 130 synchronously drives the support claw 120 to extend or retract. To ensure the extension effect of the support claw 120, guide holes 115 are provided on both sides of the first mounting base 110. One or two guide blocks are provided on the side of the support claw 120 facing the first mounting base 110, and the guide blocks are located within the guide holes 115. When the first clamping component 100 is working, the telescopic device 130 operates, and the support claws 120 on both sides of the first mounting base 110 move outward until they abut against the inner wall of the brake caliper pad support, thus fixing the brake caliper pad support. The support claw 120 is made of high-strength materials such as stainless steel. The bearing surface of the support claw 120 that contacts the brake pad support is equipped with a rubber or plastic pad to avoid damage to the surface of the brake caliper.

[0019] The second clamping component 200 includes a second mounting base 210, a mounting plate gripper 220, and a lifting device 230. For integration with the robot 10, a quick-connect coupling 400 is also provided, fixedly connected to the second mounting base 210. The lifting device 230 is preferably a telescopic cylinder, using pneumatic, electric, or hydraulic power. The second mounting base 210 is symmetrical, with a through hole in the center. The lifting device 230 is mounted on one side of the second mounting base 210, with its output end passing through the through hole and extending to the other side. Downward-extending fixing plates are provided on both sides of the second mounting base 210, each with a guide groove. The mounting plate gripper 220 is located on the side of the second mounting base 210 away from the lifting device 230. The hook 226 is connected to the base 225 of the mounting plate gripper 220 via a connecting beam 2255 located within the guide groove, moving up and down along the guide groove under the action of the lifting device 230. The claw 226 includes a fixed plate 2265 and side claws 2266. The side claws 2266 are inwardly extending structures, and each claw 226 includes two side claws 2266. The side claws 2266 are located inside the fixed plate 2265 and at both ends of the fixed plate 2265. The two side claws 2266 are used to cooperate with the mounting plate of the brake caliper. When the robot 10 drives the second clamping component 200 to clamp the brake caliper, one of the side claws 2266 passes through the notch on the side of the mounting plate from top to bottom. Then, the robot 10 drives the second clamping component 200 to move laterally, so that all the side claws 2266 move to directly below the mounting plate. The lifting device 230 drives the mounting plate claw 220 to move upward until the side claws 2266 abut against the mounting plate, thereby clamping and fixing the brake caliper mounting plate.

[0020] Furthermore, the material pallets include a pallet 61 for materials to be inspected, a pallet 62 for defective products, and a pallet 63 for qualified products. The material transfer vehicle transports the pallet 61, which contains the torque braking unit to be calibrated, to the designated workstation. Before the torque calibration process begins, the robot 10 automatically picks up different specifications of bits according to the specifications and torque requirements of different fasteners on the braking unit, and installs the required bits on the corresponding torque calibration device 30. The torque calibration device 30 receives instructions from the upper system and automatically adjusts to the required torque value. According to the braking unit inspection standards, some fasteners on the braking unit require image acquisition calibration, while others require torque calibration. When the calibration of the braking unit begins, the robot 10 holds the braking unit with the installed braking unit fixture, moves it to the working position of the image acquisition device 20, takes pictures and positions it, records the position of all fasteners on the braking unit, and then performs image calibration and torque calibration on the braking unit.

[0021] For fasteners on the braking unit that require image verification, images of the fasteners requiring verification are acquired, and rapid and accurate identification and analysis are performed based on the acquired images and image standards. If the image verification fails, robot 10 will place the defective braking unit on a manual operating table for result confirmation. If the manual inspection finds that the braking unit has repairable problems, it will be repaired and the image verification will be performed again. If the manual inspection confirms that the braking unit has irreparable quality defects, it will be placed on the defective product tray 62.

[0022] For braking units that pass image verification, after image acquisition, robot 10 moves the braking unit to the torque verification device 30. The robot aligns the fasteners requiring torque verification with the bit and performs torque testing on each fastener on the braking unit according to the set torque parameters. During the testing process, the bit size can be changed at any time, and the required torque value is readjusted after each change. After the bit change, the torque verification device 30 continues to verify the fasteners (bolts) of the braking unit to ensure the reliability and stability of the bolt connection. If the braking unit is deemed unqualified in the torque verification stage, robot 10 places it on the manual operating table. The manual inspector performs the final confirmation of the verification results. If the manual inspection finds a repairable problem in the braking unit, it is repaired and the torque verification is repeated. If the manual inspection confirms that the braking unit has an irreparable quality defect, it is placed on the non-conforming product tray 62.

[0023] After the braking unit passes torque verification and image validation, robot 10 carries it to the automatic anti-loosening line marking station. Anti-loosening line markings are drawn at designated locations on the braking unit, allowing staff to quickly identify whether bolts are loose during subsequent use and providing important reference for the maintenance and inspection of the braking unit. After marking is completed, robot 10 places the braking unit onto the qualified product tray 63.

[0024] The entire verification process was automated, ensuring quality control of the braking unit in key aspects such as torque verification, image acquisition, and anti-loosening marking, thus providing strong assurance for the reliability and safety of the braking unit.

[0025] The brake unit torque verification workstation in this application uses a brake unit gripper mounted on a robot to hold brake units and move them between a material pallet, an image acquisition device, a torque verification device, a bit storage table, and an anti-loosening line marking device. This allows for verification operations of the brake units at different verification stations. The bit gripper allows for the replacement of bits used for torque verification, and, in conjunction with tightening shafts providing different torques, the torque of the brake unit can be verified. This workstation improves the efficiency and accuracy of brake unit verification.

[0026] As one possible implementation, the torque verification device 30 also includes a tightening column 31. The torque verification device 30 is divided into a bottom torque verification device 30 and a top torque verification device 30. The tightening shaft 32 of the bottom torque verification device 30 is installed on the top of the tightening column 31, with the test end of the tightening shaft 32 facing upward. The top torque verification device 30 also includes a mounting bracket 21, which is fixedly connected to the tightening column 31. The tightening shaft 32 is fixedly connected to the mounting bracket 21, with the test end of the tightening shaft 32 facing downward.

[0027] The bottom torque verification device 30 and the top torque verification device 30 can respectively verify the torque of the fasteners at the bottom and top of the braking unit, ensuring the verification of all fasteners on the braking unit.

[0028] As one possible implementation, the image acquisition device 20 includes a mounting frame 21, a first image acquisition device 22, and a second image acquisition device 23; the first image acquisition device 22 and the second image acquisition device 23 are respectively installed on the top and middle of the mounting frame 21, with the first image acquisition device 22 acquiring images downwards and the second image acquisition device 23 acquiring images to the side.

[0029] The image acquisition device 20 can acquire the position of all fasteners on the braking unit, providing basic data for torque verification, and can also verify whether the fasteners that need image calibration are qualified; the first image acquisition device 22 and the second image acquisition device 23 set up realize the all-round acquisition of the braking unit.

[0030] As one possible implementation, the material pallet includes a material pallet 61 to be inspected, a non-conforming product pallet 62, and a conforming product pallet 63; the material pallet 61 to be inspected, the non-conforming product pallet 62, and the conforming product pallet 63 are arranged side by side.

[0031] By setting up trays 61 for materials to be tested, 62 for defective products, and 63 for qualified products, different types of braking units can be stored separately.

[0032] As one possible implementation, the verification workstation also includes a manual inspection workbench 70; the manual inspection workbench 70 is located at the entrance of the verification workstation and on the side of the material pallet away from the anti-loosening line marking device 40.

[0033] The manual inspection workbench 70 can manually inspect braking units that fail image verification and torque verification, re-inspect and re-verify braking units that pass manual verification, and mark braking units that fail manual verification as defective products. Through the manual inspection workbench 70, the re-verification of braking units that fail image verification and torque verification is realized.

[0034] As one possible implementation, the verification workstation also includes a material transfer vehicle for moving material pallets.

[0035] The material transfer vehicle enables the automatic transfer of material pallets.
