Description
Hydraulic hybrid high torque brake Technical Field

[0002] Hydraulic torque wrenches, as commonly used tightening and loosening tools, are widely used in industrial production, machinery maintenance, and other fields. Powered by a hydraulic system, they can output significant torque. When testing hydraulic torque wrenches, it is necessary to accurately control and measure their output torque. Currently, the commonly used method is to use a magnetic particle controller and a mechanical disc brake device to achieve torque testing.
[0003] Existing magnetic particle controllers and mechanical disc brake devices have shortcomings. On the one hand, they can only generate limited braking torque, and with the increasing torque requirements of industry, traditional devices are unable to meet the needs of high torque testing. On the other hand, these devices are bulky, inconvenient to install and use, and occupy a large space, which is not conducive to the miniaturization and integration design of the equipment.
[0004] The reason for this problem is that the braking principle and structural design of traditional devices have limitations. The braking torque of a magnetic powder controller is limited by the characteristics of the magnetic powder and the magnetic field strength, while the braking torque of a mechanical disc brake is limited by the contact area of the mechanical friction pair and the material properties, making precise measurement impossible. Therefore, we propose a hydraulic hybrid ultra-high torque brake to solve the above problems. Summary of the Invention

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0028] This application provides a hydraulic hybrid ultra-high torque brake, which solves the shortcomings of existing magnetic powder controllers and mechanical disc brake devices. On the one hand, they can only generate limited braking torque, and with the increasing torque requirements of industry, traditional devices are unable to meet the needs of high torque testing. On the other hand, these devices are bulky, inconvenient to install and use, occupy a large space, and are not conducive to the miniaturization and integrated design of equipment.
[0029] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0030] This invention provides a hydraulic hybrid ultra-high torque brake as shown in Figures 1-2.
[0031] Example 1: Includes a device body 1, with a hexagonal rotating shaft 2 inside the device body 1, and a braking unit 3 inside the device body 1. The braking unit 3 includes a quick connector 31, a piston 32, and a friction element 33.
[0032] Quick connector 31 is located at the bottom of the device body 1 and communicates with the device body 1. Quick connector 31 is used to inject hydraulic oil into the interior of the device body 1. Piston 32 is slidably connected to the interior of the device body 1. Hydraulic oil is used to push piston 32 to move vertically inside the device body 1. Friction element 33 is sleeved on the outer surface of hexagonal rotating shaft 2. The end of piston 32 is in close contact with friction element 33. Piston 32 is used to prevent friction element 33 from rotating.
[0033] The body 1 includes a friction plate housing 11, an upper bearing cover plate 12, and a lower bearing seat plate 13. The upper bearing cover plate 12 is fixedly mounted on the friction plate housing 11. The lower bearing seat plate 13 is located below the friction plate housing 11. Springs 34 are provided on both sides of the piston 32. The ends of the springs 34 abut against the inner wall of the friction plate housing 11. A sealing ring 35 is provided inside the friction plate housing 11. The sealing ring 35 is tightly fitted with the piston 32. Protrusions 36 are provided on both sides of the hexagonal rotating shaft 2. The protrusions 36 are movably engaged inside the friction plate rotor 331. A support plate 37 is provided below the hexagonal rotating shaft 2. The support plate 37 is used to support the friction component 33.
[0034] In this embodiment, the spring 34 pushes the piston 32 to reset when the hydraulic oil pressure disappears, ensuring the normal operation of the brake. An oil drain is provided on one side of the body 1 to drain excess hydraulic oil. The sealing ring 35 fits tightly against the piston 32 to prevent hydraulic oil leakage and ensure the sealing of the hydraulic system. When braking the hexagonal rotating shaft 2 is required, hydraulic oil is injected into the body 1 through the quick connector 31. The hydraulic oil pushes the piston 32 upward, causing it to contact the friction plate 333, generating friction and preventing the friction plate 33 from rotating, thus achieving braking of the hexagonal rotating shaft 2. When braking is no longer needed, the injection of hydraulic oil stops, the spring 34 pushes the piston 32 to reset, the friction plate 333 separates from the inner wall of the body 1, and the hexagonal rotating shaft 2 can rotate freely.
[0035] This utility model discloses a hydraulic hybrid ultra-high torque brake, which is based on Embodiment 1 and more specifically, as shown in Figures 1, 3, and 4.
[0036] Example 2: Includes a device body 1, with a hexagonal rotating shaft 2 inside the device body 1, and a braking unit 3 inside the device body 1. The braking unit 3 includes a quick connector 31, a piston 32, and a friction element 33.
[0037] Quick connector 31 is located at the bottom of the device body 1 and communicates with the device body 1. Quick connector 31 is used to inject hydraulic oil into the interior of the device body 1. Piston 32 is slidably connected to the interior of the device body 1. Hydraulic oil is used to push piston 32 to move vertically inside the device body 1. Friction element 33 is sleeved on the outer surface of hexagonal rotating shaft 2. The end of piston 32 is in close contact with friction element 33. Piston 32 is used to prevent friction element 33 from rotating.
[0038] Friction component 33 includes friction plate rotor 331 and sliding groove 332; the sliding groove 332 is formed on the outer surface of friction plate rotor 331 and the sliding groove 332 is distributed in a ring array; friction component 33 includes friction plate 333 and top cover 334.
[0039] Friction plates 333 are slidably connected inside the slide groove 332, and the friction plates 333 are arranged in a vertical array; the top cover 334 is located above the friction plate rotor 331, and the bottom of the top cover 334 abuts against the top of the friction plate rotor 331. The friction component 33 also includes a locking block 335 and a bolt 336; the locking block 335 is fixedly assembled below the top cover 334, and the locking blocks 335 are distributed in a ring array. The locking blocks 335 are slidably connected inside the slide groove 332; the bolt 336 is located inside the locking block 335, and the bolt 336 is threadedly engaged with the friction plate rotor 331.
[0040] In this embodiment, the friction plate 333 can slide within the groove 332. When the piston 32 pushes the friction element 33, the friction plate 333 contacts the piston 32, generating frictional force, thereby preventing the friction element 33 from rotating and achieving braking. The top cover 334 can be fixed to the friction plate rotor 331 by bolts 336, which facilitates the installation and replacement of the friction plate 333 and prevents the friction plate 333 from detaching from the inside of the friction plate rotor 331.
[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
