Description

Technical Field

[0001] This utility model relates to the field of spring brake processing technology, specifically a spring brake energy storage spring pressing tool. Background Technology

[0002] A brake is a device that decelerates, stops, or keeps a moving part (or machine) at a stop. It is a mechanical component that stops or slows down moving parts in machinery, commonly known as a brake or brake. A brake mainly consists of a bracket, braking components, and an operating device. Some brakes also have an automatic adjustment device for the braking component clearance. To reduce braking torque and structural dimensions, brakes are usually mounted on the high-speed shaft of the equipment. However, for large equipment with high safety requirements (such as mine hoists and elevators), brakes should be mounted on the low-speed shaft closer to the working part of the equipment.

[0003] Currently, the pressing of springs on brakes is generally done manually. However, due to the large load on some brake springs, manual pressing is quite laborious, so pressing fixtures are used. For example, CN203305160U discloses a spring pressing fixture, which includes a base plate with a vertically arranged base cylinder fixed at one end. The upper end of the base cylinder is threaded to a stud coaxially arranged therewith. The upper end of the stud is threaded to a horizontally arranged crossbeam. A vertically arranged pressure rod is connected to the crossbeam via a slider, wherein the slider and the pressure rod are threaded together. The upper end of the pressure rod passes through a horizontally arranged rotating rod. The lower end of the pressure rod is connected to a detachable spring-loaded auxiliary tool. The bottom surface of the spring-loaded auxiliary tool has a cavity with a diameter of 20mm-56mm. The length of the pressure rod is equal to or greater than 320mm, and the length of the stud is equal to or greater than 370mm.

[0004] However, this spring pressing fixture lacks protective functions during use. Due to the large elasticity of the spring, it may loosen and spring open during the pressing process, which may cause accidental injury. Therefore, a spring brake energy storage spring pressing fixture is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a spring brake energy storage spring pressing fixture, which has advantages such as easy protection. It solves the problem that existing spring pressing fixtures lack protective functions during use, and that the large elasticity of the spring may cause accidental injury if it loosens and springs open during the pressing process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spring brake energy storage spring pressing fixture, comprising a base, a vertical plate and a top plate, wherein a clamping mechanism is provided on the top of the base, a hydraulic rod is fixedly installed on the upper side of the top plate, and a pressing assembly corresponding to the clamping mechanism is provided on the lower side of the hydraulic rod.

[0007] The clamping mechanism includes two drive cylinders fixedly installed on the top of the base, and clamping blocks are fixedly installed on the output shafts of the two drive cylinders.

[0008] The press-fit assembly includes a mounting plate fixedly mounted on the hydraulic rod output shaft. A connecting shaft is fixedly connected to the bottom of the mounting plate, and a press-fit plate is fixedly connected to the bottom of the connecting shaft. A protective plate is provided between the press-fit plate and the mounting plate. A protective cover is fixedly connected to the bottom of the protective plate, and a buffer assembly is provided between the mounting plate and the protective plate.

[0009] Furthermore, the output shafts of the two drive cylinders correspond to each other, the base is fixedly connected to the lower part of the vertical plate, and the top plate is fixedly installed on the top of the vertical plate.

[0010] Furthermore, the inner side of the protective plate is provided with an insertion port that is compatible with the connecting shaft, and the connecting shaft passes through the inner side of the insertion port.

[0011] Furthermore, the upper wall of the pressing plate abuts against the lower wall of the protective plate, and the diameters of both the pressing plate and the mounting plate are larger than the inner diameter of the socket.

[0012] Furthermore, a first guide rod is fixedly connected to the top of the protective plate, and a fixed sliding sleeve is fixedly installed on the upper side of the top plate, with the first guide rod movably inserted into the upper side of the fixed sliding sleeve.

[0013] Furthermore, a second guide rod is fixedly connected to the top of the protective plate, and a movable sliding sleeve is fixedly connected to the side of the mounting plate. The movable sliding sleeve is movably sleeved on the outer wall of the second guide rod.

[0014] Furthermore, the buffer assembly includes a fixed rod fixedly connected to the top of the protective plate, a sleeve sleeved on the upper side of the fixed rod, the upper end of the sleeve being fixedly connected to the mounting plate, and a buffer spring provided between the sleeve and the protective plate, the buffer spring being sleeved on the outer wall of the fixed rod.

[0015] Compared with the prior art, this utility model provides a spring brake energy storage spring pressing fixture, which has the following beneficial effects:

[0016] 1. This spring brake storage spring pressing fixture uses a drive cylinder to move clamping blocks, which, in conjunction with the two clamping blocks, hold and fix the brake housing. A hydraulic rod then moves the mounting plate, connecting shaft, and pressing plate downwards, pressing the spring into the brake housing. During pressing, a protective plate and cover cover the upper part of the brake housing to prevent accidental loosening and potential safety hazards, providing excellent protection. This solves the problem of existing spring pressing fixtures lacking protective functions and potentially causing injury due to the spring's high elasticity and potential loosening during pressing.

[0017] 2. This spring brake energy storage spring pressing fixture, when the protective plate is restricted from moving further by the brake housing, and the pressing plate continues to move deeper, causes the movable sliding sleeve outside the mounting plate to move along the outer wall of the second guide rod, and drives the sleeve to move downward along the outer wall of the fixed rod, so that the pressing plate always maintains a stable movement trajectory. It is flexible in use and can adaptively adjust the distance between the pressing plate and the protective plate, which facilitates processing. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4 The spring brake energy storage spring pressing fixture in this embodiment includes a base 1, a vertical plate 2 and a top plate 3. The base 1 is fixedly connected to the lower part of the vertical plate 2, and the top plate 3 is fixedly installed on the top of the vertical plate 2. A clamping mechanism is provided on the top of the base 1. The clamping mechanism includes two drive cylinders 4 fixedly installed on the top of the base 1. A clamping block 5 is fixedly installed on the output shaft of each of the two drive cylinders 4, and the output shafts of the two drive cylinders 4 correspond to each other.

[0025] In this embodiment, a hydraulic rod 6 is fixedly installed on the upper side of the top plate 3, and a pressing assembly corresponding to the clamping mechanism is provided on the lower side of the hydraulic rod 6. The pressing assembly includes a mounting plate 7 fixedly installed on the output shaft of the hydraulic rod 6, a connecting shaft 8 fixedly connected to the bottom of the mounting plate 7, a pressing plate 9 fixedly connected to the bottom of the connecting shaft 8, a protective plate 10 between the pressing plate 9 and the mounting plate 7, and a protective cover 11 fixedly connected to the bottom of the protective plate 10.

[0026] The inner side of the protective plate 10 is provided with a socket that is compatible with the connecting shaft 8. The connecting shaft 8 passes through the inner side of the socket. The upper wall of the pressing plate 9 is close to the lower wall of the protective plate 10. The diameters of the pressing plate 9 and the mounting plate 7 are both larger than the inner diameter of the socket. Through the mutual restraint of the pressing plate 9 and the mounting plate 7, the protective plate 10 will not separate from the connecting shaft 8.

[0027] It should be noted that a first guide rod 12 is fixedly connected to the top of the protective plate 10, and a fixed sliding sleeve 13 is fixedly installed on the upper side of the top plate 3. The first guide rod 12 is movably inserted into the upper side of the fixed sliding sleeve 13. The cooperation between the fixed sliding sleeve 13 and the first guide rod 12 can guide the protective plate 10.

[0028] It should be noted that the top of the protective plate 10 is fixedly connected to the second guide rod 14, and the side of the mounting plate 7 is fixedly connected to the movable sliding sleeve 15. The movable sliding sleeve 15 is movably sleeved on the outer wall of the second guide rod 14, and the mounting plate 7 can be guided by the cooperation of the movable sliding sleeve 15 and the second guide rod 14.

[0029] In this embodiment, a buffer assembly is provided between the mounting plate 7 and the protective plate 10. The buffer assembly includes a fixing rod 16 fixedly connected to the top of the protective plate 10, a sleeve 17 sleeved on the upper side of the fixing rod 16, the upper end of the sleeve 17 being fixedly connected to the mounting plate 7, and a buffer spring 18 provided between the sleeve 17 and the protective plate 10. The buffer spring 18 is sleeved on the outer wall of the fixing rod 16. The cooperation of the sleeve 17, the fixing rod 16 and the buffer spring 18 provides buffer for the mounting plate 7, thereby improving the stability of the structure.

[0030] The working principle of the above embodiments is as follows:

[0031] In use, the drive cylinder 4 is activated to move the clamping block 5. With the cooperation of the two clamping blocks 5, the brake housing is clamped and fixed. The hydraulic rod 6 is activated to move the mounting plate 7, connecting shaft 8 and pressing plate 9 downward. The pressing plate 9 presses the spring into the brake housing. During the pressing process, the protective plate 10 and the protective cover 11 cover the upper part of the brake housing to prevent accidental loosening and popping out, which may cause safety hazards. Since the protective plate 10 cannot continue to move due to the restriction of the brake housing, when the pressing plate 9 continues to move deeper, the movable sliding sleeve 15 outside the mounting plate 7 moves along the outer wall of the second guide rod 14, and drives the sleeve 17 to move downward along the outer wall of the fixed rod 16, so that the pressing plate 9 always maintains a stable movement trajectory.

[0032] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.

[0033] It should be noted that the orientations or positional relationships indicated herein are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of facilitating the description of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
