Description

Technical Field

[0001] This utility model relates to the field of hydraulic component technology, specifically a fixing fixture for testing the performance of hydraulic components. Background Technology

[0002] An airplane is a heavier-than-air aircraft that flies within the atmosphere, powered by an engine that generates forward thrust or pull and by fixed wings that generate lift. Aircraft components are divided into various types, among which hydraulic components are an essential functional component in the drive area, and therefore require great attention in their testing.

[0003] A search revealed a Chinese patent document disclosing a fixing fixture for testing the performance of hydraulic components [Application No.: CN202221066864.X]. This fixing fixture for testing the performance of hydraulic components includes two limiting plates movably mounted on the upper end of a base. Each limiting plate has a first groove on its inner side, and a first movable plate is movably connected to each of the two first grooves. A probe is mounted on the inner side of each limiting plate. A first sliding groove is formed at the upper end of the base, and the two limiting plates are slidably connected to the first sliding groove. Support plates are provided at both ends of the front end of the base, and a second movable plate is movably mounted on the upper end of each of the two support plates.

[0004] The clamp disclosed in this patent replaces the first movable plate by means of a magnet. However, the limiting effect of the magnet is limited. When clamping and fixing the hydraulic components, the pressure can easily cause the first movable plate to shift position and the magnet to be over-compressed and broken, thus reducing the applicability of the clamp in use.

[0005] Meanwhile, when using this clamp, regardless of the size of the hydraulic component, the drive motor needs to be turned on to achieve the fixing effect. After changing the size of the hydraulic component, the clamp requires the drive motor to rotate for a longer time, which not only affects the fixing efficiency of the hydraulic component, but also causes the clamp to consume more energy when in use. Utility Model Content

[0006] The purpose of this invention is to provide a fixing fixture for testing the performance of hydraulic components, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fixing fixture for testing the performance of hydraulic components, comprising a mounting frame and a mounting groove formed on its top, and further comprising:

[0008] A bidirectional threaded rod rotates within the mounting groove. Sleeves are threadedly connected to both sides of the surface of the bidirectional threaded rod. A mounting plate is fixedly connected to one side of the top of the sleeve. An electric push rod is bolted to one side of the mounting plate. A fixing plate is fixedly connected to the output shaft of the electric push rod.

[0009] A fixing frame is fixed to the top of the fixing plate. A positioning groove is provided on one side of the fixing frame. A positioning block is slidably connected to the inner cavity of the positioning groove. A clamping plate is fixedly connected to one side of the positioning block. A positioning mechanism is installed on one side of the inner cavity of the positioning groove.

[0010] Preferably, the positioning mechanism includes compression springs fixed at two locations on one side of the positioning groove cavity and a movable block fixed at the other end thereon, with a movable frame fixedly connected to one side of the movable block.

[0011] Preferably, a locking rod is fixedly connected to the bottom of the inner cavity of the positioning groove, and a through groove is opened on the surface of the positioning block, and the surface of the locking rod is slidably connected to the inner wall of the through groove.

[0012] Preferably, guide grooves are provided on both sides of the top of the mounting frame, and guide blocks are fixedly connected to the inner cavity of the guide grooves. The top of the guide blocks is fixedly connected to the bottom of the mounting frame.

[0013] Preferably, one end of the bidirectional threaded rod is fixedly connected to a bearing seat, and the other side of the bearing seat is fixedly connected to the inner wall of the mounting groove.

[0014] Preferably, one side of the movable block and one side of the bottom of the positioning block are both designed with an inclined structure, and the surface of the movable frame is used in conjunction with the positioning block.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention, through the cooperation of a positioning mechanism and a positioning block, facilitates the fixing and replacement of the clamping plate. This not only makes the clamping plate more stable during use but also allows for easy disassembly and replacement, effectively improving the applicability of the fixture. Furthermore, the cooperation of the bidirectional threaded rod and the sleeve allows for significant adjustment of the clamping plate. When continuously testing hydraulic components of the same size, the electric push rod can be used to directly clamp the hydraulic components with the clamping plate, enabling rapid fixing of the hydraulic components and saving energy consumption. This solves the problems of existing fixtures being inconvenient to use and having poor applicability. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-4As shown, a fixing fixture for testing the performance of hydraulic components includes a mounting frame 1. A mounting groove 2 is formed on the top of the mounting frame 1. A bidirectional threaded rod 3 is rotatably connected to the inner cavity of the mounting groove 2. Sleeves 4 are threadedly connected to both sides of the surface of the bidirectional threaded rod 3. Under this action, when the bidirectional threaded rod 3 rotates, the two sleeves 4 can move simultaneously in opposite directions due to the action of the threads on its surface. A bearing seat 17 is fixedly connected to one end of the bidirectional threaded rod 3, and the other side of the bearing seat 17 is fixedly connected to the inner wall of the mounting groove 2. Under this action, the bearing seat 17 supports one end of the bidirectional threaded rod 3, making it more stable during rotation and preventing instability during rotation from affecting its movement with the sleeves. The sleeve 4 is connected by a threaded connection. A mounting plate 5 is fixedly connected to one side of the top of the sleeve 4. An electric push rod 6 is bolted to one side of the mounting plate 5. The output shaft of the electric push rod 6 is fixedly connected to a fixing plate 7. A fixing bracket 8 is fixedly connected to the top of the fixing plate 7. The surface of the fixing bracket 8 is slidably connected to the surface of the mounting bracket 1. This reduces the pressure of the fixing bracket 8 on the electric push rod 6, thereby reducing the possibility of damage to the output shaft of the electric push rod 6 due to excessive force. Guide grooves 15 are provided on both sides of the top of the mounting bracket 1. Guide blocks 16 are fixedly connected to the inner cavity of the guide grooves 15. The top of the guide blocks 16 is fixedly connected to the bottom of the fixing bracket 8. This allows the fixing bracket 8 to be guided when it moves through the cooperation of the guide grooves 15 and the guide blocks 16. This makes the movement more stable, effectively reducing the possibility of positional deviation due to instability of the fixing frame 8 during movement. A positioning groove 9 is provided on one side of the fixing frame 8, and a positioning block 10 is slidably connected to the inner cavity of the positioning groove 9. A clamping plate 11 is fixedly connected to one side of the positioning block 10. The clamping plate 11 is used to limit the hydraulic components that need to be fixed, making the clamping device more convenient. When it is necessary to limit hydraulic components of different sizes, the bidirectional threaded rod 3 can be rotated to move the mounting plate 5 through the sleeve 4 until the position of the clamping plate 11 is adapted to the surface of the hydraulic component. Then, the electric push rod 6 is activated. Under the action of the electric push rod 6, the clamping plate is moved through the cooperation of the fixing plate 7 and the fixing frame 8. The hydraulic components are clamped and fixed in place to prevent easy movement. When it is necessary to fix hydraulic components of the same size, the electric push rod 6 can be directly activated to fix and release the limit, making the fixture more convenient to use and effectively improving its applicability. A positioning mechanism 12 is installed on one side of the inner cavity of the positioning groove 9. The positioning mechanism 12 can limit the positioning block 10, so that when it is necessary to fix hydraulic components of different shapes, the clamping plate 11 can be moved out of the positioning groove 9, which facilitates the replacement of the clamping plate 11. Under the action of the positioning mechanism 12, it is also convenient to fix the positioning block 10, so that the replaced clamping plate 11 is more stable during use.This allows the clamp to select a suitable clamping plate 11 based on the shape of the hydraulic component during use. A locking rod 13 is fixedly connected to the bottom of the inner cavity of the positioning groove 9. A through groove 14 is formed on the surface of the positioning block 10. The surface of the locking rod 13 is slidably connected to the inner wall of the through groove 14. Under this action, the cooperation between the locking rod 13 and the through groove 14 enhances the limiting effect on the positioning block 10. Therefore, when the positioning block 10 is fixed inside the positioning groove 9 under the action of the positioning mechanism 12, the positioning block 10 is more stable, effectively improving the limiting effect on the positioning block 10.

[0024] The positioning mechanism 12 includes two compression springs 122 fixed to one side of the inner cavity of the positioning groove 9. The other end of the compression spring 122 is fixedly connected to a movable block 121. One side of the movable block 121 is fixedly connected to a movable frame 123. The other side of the movable frame 123 extends through to the outside of the fixed frame 8 and is movably connected to the inner wall of its penetration point. Under this action, the positioning block 10 can be blocked by the cooperation of the compression spring 122 and the movable block 121, so that it will not move easily inside the positioning groove 9. When it is necessary to release the restriction on the positioning block 10, the position of the movable block 121 can be adjusted by pulling the movable frame 123. One side of the movable block 121 and the bottom side of the positioning block 10 are both inclined structure designs. The surface of the movable frame 123 is used in conjunction with the positioning block 10. Under this action, the positioning block 10 can be stuck inside the positioning groove 9 by the action of the shape. The movable block 121 can enter the other side of the inner cavity of the positioning groove 9 by the shape, so that the operator can install the positioning block 10 more conveniently and effectively improve the applicability of the fixture.

[0025] Working principle: First, when the clamping plate 11 needs to be replaced, simply pull the movable frame 123 so that the movable block 121 no longer obstructs the positioning block 10. Then, the operator removes the positioning block 10 through the clamping plate 11. After selecting a suitable clamping plate 11, the operator installs the clamping plate 11 through the cooperation of the positioning block 10 and the positioning mechanism 12. This not only facilitates the replacement of the clamping plate 11 but also effectively improves the working efficiency of the fixture. When a significant adjustment to the position of the clamping plate 11 is required, the operator can directly... Rotate the bidirectional threaded rod 3 so that it drives the sleeve 4 and the parts on its surface to move under the action of the surface thread until the clamping plate 11 is moved to the appropriate position. Then turn on the electric push rod 6. Under its action, the clamping plate 11 can be squeezed and fixed by the cooperation of the fixing plate 7 and the fixing frame 8. This method allows the operator to continuously test the hydraulic components of the same size without having to make a large adjustment to the position of the clamping plate 11 each time, thus making the fixture more convenient to use and effectively improving the applicability of the fixture.
