Abstract
Description
Technical Field
[0001] This utility model relates to the field of fixing mechanism technology, and in particular to a fixing mechanism for automobile brakes. Background Technology
[0002] A fixing mechanism is a device that facilitates adjustment after clamping the brake. This utility model (CN222386909U) discloses a fixing mechanism for an automobile brake, including an operating table. The top of the operating table has a first sliding groove, within which a first slider is slidably connected. A second threaded rod is rotatably inserted between the inner walls of both ends of the first sliding groove, and the second threaded rod is threadedly inserted into the first slider. A tray is fixedly connected to the top of the first slider. An electric push rod is fixedly connected to the top of the operating table, and a slide cylinder is fixedly connected to the top of the electric push rod. A second slider is slidably inserted into one end of the slide cylinder, and a third threaded rod is threadedly inserted into the other end of the slide cylinder. This utility model uses the second threaded rod to move the first slider within the first sliding groove, thereby moving the placement plate. This adjusts the position of the tray. Then, by turning the third threaded rod, the second slider is moved, thus adjusting its position to clamp a large automobile brake. In practical applications, it is somewhat inadequate. The device relies on only two sets of vertical devices to clamp the brake, which is not stable enough and may fall off during operation, causing danger. Improvement is needed. Utility Model Content
[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.
[0004] The present invention adopts the following technical solution: a car brake fixing mechanism, including a housing, a groove is provided on the surface of the housing, a pawl is slidably connected inside the groove, a movable plate is fixedly installed on the bottom surface of the pawl, a connecting rod is rotatably connected to the surface of the movable plate, a rotating plate is rotatably connected to the other end of the connecting rod, a protruding rod is rotatably connected to the rotating plate, and one end of the protruding rod is fixedly installed inside the housing.
[0005] Preferably, the number of sliding grooves is four sets, which are distributed diagonally on the surface of the outer shell. Here, the four sets of sliding grooves, symmetrically distributed on the diagonal of the outer shell surface, ensure that the four jaws are evenly distributed around the brake. This layout significantly improves the stability and balance of the clamping, effectively preventing the brake from tilting or shifting during the fixing process, and is particularly suitable for brake operations requiring precise alignment and stable support.
[0006] Preferably, there are four sets of connecting rods, each rotatably connected to one of the four corners of the rotating plate. Here, four sets of connecting rods are used, each connected to one of the four corners of the rotating plate. This design ensures that a single power input can precisely and synchronously drive all four jaws to move inward or outward simultaneously. This eliminates the risk of uneven force on the jaws or jamming due to asynchronous movements, improving the reliability and clamping accuracy of the mechanism.
[0007] Preferably, a connecting block is fixedly mounted on the surface of one of the sets of movable plates. A lead screw is internally threaded onto the connecting block, and a handwheel is fixedly mounted at one end of the lead screw. Here, the connecting block, lead screw, and handwheel mounted on one of the sets of movable plates provide a mechanism for manually and precisely adjusting the initial position or clamping range of the chuck. The lead screw drive has a self-locking characteristic, locking the position after adjustment to prevent accidental loosening. This allows the mechanism to adapt to brakes of different sizes and specifications, improving versatility and ease of operation.
[0008] Preferably, a bracket is fixedly mounted on the side of the housing, and a collar is fixedly mounted on one end of the bracket. A slider is slidably connected inside the collar, and a second lead screw is threadedly connected inside the slider. A second handwheel is fixedly mounted on one end of the second lead screw. Here, the bracket and collar provide a support track for the entire hydraulic clamping assembly. The slider slides within the collar in conjunction with the second lead screw and the second handwheel, enabling precise and flexible manual adjustment of the hydraulic cylinder and clamping block along the axial position of the brake. This allows the mechanism to accurately position the specific part of the brake that needs to be clamped, enhancing its applicability and operational flexibility.
[0009] Preferably, a hydraulic cylinder is fixedly mounted at one end of the slider, and a clamping block is fixedly mounted at the output end of the hydraulic cylinder. Here, the hydraulic cylinder, as a power source, provides a strong and controllable axial clamping force, ensuring that the brake is firmly pressed against the worktable or positioning surface during operation, preventing movement or vibration. The clamping block, as an actuator, is designed to increase friction, disperse the clamping force, and protect the brake surface from hard damage. This is an important supplement to radial jaw clamping, providing all-around fixation.
[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting up a shell, sliding groove, cleats, moving blocks, connecting rods and rotating plate structure, rotating the No. 1 handwheel drives the No. 1 lead screw, the lead screw rotates and drives the connecting block and moving plate to move, the connecting rod drives the rotating plate so that the four sets of moving plates move simultaneously under the drive of the connecting rod, thus realizing stable clamping of the brake. By using multiple sets of cleats to clamp the brake simultaneously, the brake is prevented from falling off due to unstable clamping.
[0011] 2. In this utility model, by setting up a bracket, collar, slider, second lead screw, second handwheel, hydraulic cylinder, and clamping block structure, the bracket and collar provide a support track for the entire hydraulic clamping assembly. The slider slides within the collar, engaging with the second lead screw and second handwheel, enabling precise and flexible manual adjustment of the hydraulic cylinder and clamping block along the axial position of the brake. This allows the mechanism to accurately position the specific part of the brake that needs to be clamped, enhancing its applicability and operational flexibility. Attached Figure Description

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0016] Example 1 Please see Figure 1-4This utility model provides a technical solution: a car brake fixing mechanism, including a housing 1. A groove 2 is formed on the surface of the housing 1. A claw 3 is slidably connected inside the groove 2. A movable plate 4 is fixedly installed on the bottom surface of the claw 3. A connecting rod 5 is rotatably connected to the surface of the movable plate 4. A rotating plate 6 is rotatably connected to the other end of the connecting rod 5. A protruding rod 7 is rotatably connected to the rotating plate 6. One end of the protruding rod 7 is fixedly installed inside the housing 1. There are four sets of grooves 2, distributed diagonally on the surface of the housing 1. The four sets of grooves 2, symmetrically distributed on the diagonal of the surface of the housing 1, ensure that the four claws 3 are evenly distributed around the brake. This layout significantly improves the stability and balance of the clamping, effectively preventing the brake from tilting or shifting during the fixing process. It is particularly suitable for brake operations requiring precise centering and stable support. There are four sets of connecting rods 5, rotatably connected to the four corners of the rotating plate 6. This design ensures that a single power input can precisely and synchronously drive all four jaws 3 to move inward or outward simultaneously. This eliminates the risk of uneven force on the jaws 3 or mechanism jamming due to asynchronous movements, improving the reliability and clamping accuracy of the mechanism. A connecting block 8 is fixedly mounted on the surface of one set of movable plates 4. The connecting block 8 is internally threaded with a lead screw 9, and a handwheel 10 is fixedly mounted at one end of the lead screw 9. Through the connecting block 8, lead screw 9, and handwheel 10 mounted on one set of movable plates 4, a mechanism for manually and precisely adjusting the initial position or clamping range of the jaws 3 is provided. The lead screw 9 transmission has a self-locking characteristic, locking the position after adjustment to prevent accidental loosening. This allows the mechanism to adapt to brakes of different sizes and specifications, improving versatility and ease of operation.
[0017] Example 2 Please see Figure 1-2A bracket 11 is fixedly mounted on the side of the outer casing 1. A collar 12 is fixedly mounted on one end of the bracket 11. A slider 13 is slidably connected inside the collar 12. A second lead screw 14 is threadedly connected inside the slider 13. A second handwheel 15 is fixedly mounted on one end of the second lead screw 14. The bracket 11 and collar 12 provide a support track for the entire hydraulic clamping assembly. The slider 13 slides within the collar 12 in conjunction with the second lead screw 14 and the second handwheel 15, enabling precise and flexible manual adjustment of the hydraulic cylinder 16 and the clamping block 17 along the axial position of the brake. This allows the mechanism to accurately position the brake at the specific part that needs to be clamped, enhancing its applicability and operational flexibility. A hydraulic cylinder 16 is fixedly mounted on one end of the slider 13, and a clamping block 17 is fixedly mounted on the output end of the hydraulic cylinder 16. The hydraulic cylinder 16 serves as a power source, providing a strong and controllable axial clamping force to ensure that the brake is firmly clamped onto the worktable or positioning surface during operation, preventing movement or vibration. The clamping block 17, as the actuating element, is designed to increase friction, disperse clamping force, and protect the brake surface from hard damage. This is an important complement to the radial jaws 3, providing all-around fixation.
[0018] Working principle: First, the operator rotates the first handwheel 10 according to the diameter of the brake to be fixed, driving the first lead screw 9 to rotate. This causes the threaded connecting block 8 and the corresponding moving plate 4 to move along the slide groove 2. The moving plate 4 pushes the rotating plate 6 to rotate via the connecting rod 5. When the rotating plate 6 rotates, it drives the other three moving plates 4 and their claws 3 synchronously via the other three sets of connecting rods 5 to slide synchronously inward or outward along the diagonal direction of the outer shell 1 within the slide groove 2, until the four sets of claws 3 evenly abut against the outer edge of the brake to complete the radial pre-positioning. The self-locking characteristic of the first lead screw 9... This position can be maintained; next, adjust the position of the hydraulic components along its axis according to the position where the brake needs to be pressed, turn the second handwheel 15 to drive the second lead screw 14 to rotate, and drive the slider 13 to slide axially within the collar 12 of the bracket 11, thereby adjusting the axial position of the hydraulic cylinder 16 and the clamping block 17 fixed on the slider 13, so that they are aligned with the brake to be pressed surface. Finally, start the hydraulic cylinder 16, and its output end pushes the clamping block 17 to axially press the brake with a controllable and powerful pressure. The design of the clamping block 17 ensures that the pressing force is evenly distributed and prevents surface damage.
[0019] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
