Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of engine support, especially to an engine support bearing detection device. BACKGROUND

[0002] The engine support, also known as the support foot, is a necessary structure for supporting, bearing and stabilizing the engine. If the support is problematic, it will cause the engine to shake and the support to deform. Therefore, the bearing detection device needs to be used to test the bearing capacity of the support during the production and processing of the engine support.

[0003] For example, Chinese utility model patent (CN221148355U) discloses a kind of engine support bearing detection devices for taking things, which is described as follows: "by the setting of base, drive motor, transmission belt, turntable, screw rod, movable block and support frame, by placing the motor support to be detected on the placing plate, then clamping and fixing, then starting drive motor switch, driving the external transmission belt and turntable to rotate, while the screw rod fixedly installed at one end of the turntable is rotated, the movable block is driven to slide together with the support frame and the motor support above the screw rod to the detection area, which avoids accidents and ensures the safety of workers without the need for workers to put their hands into the detection area.", It is also described that: "the above-mentioned patent introduces a carton bearing detection, and the bearing detection property is the same as the motor support. In this patent, the carton is directly placed in the detection area, and if the worker directly puts his hand in, there will be a certain safety hazard. When mechanical failure occurs or the mechanical corners of the detection area are accidentally touched, hand injury is likely to occur, thus there is a certain risk."

[0004] In summary, the existing technology uses a cylinder to drive a clamping plate to clamp and position the motor support. However, this method has the following technical problems: the clamping plate of the above-mentioned device is a flat plate, and the shapes and sizes of different motor supports vary greatly. The above-mentioned device only relies on the clamping plate to clamp and fix the motor support, and the clamping plate contacts the convex surface of the motor support, causing uneven stress on the motor support when it is clamped, which affects the stability and fixing effect of the support. Therefore, the present application proposes an engine support bearing detection device to solve the technical problems mentioned in the above-mentioned patent and provides a new technical solution.

The clamping plates are installed on the outer shape of the engine support body to clamp the engine support body, so that the clamping plate and the engine support body are adapted to the concave-convex surface, so that the force applied to the engine support body is uniform, thereby ensuring the stability of the clamping and limiting of the engine support body. At the same time, since the clamping plate is adapted to the engine support body, unnecessary damage or indentation is caused to the surface of the engine support body during clamping of the engine support body by the clamping plate, and the installation and disassembly of the clamping plate are more convenient.

Specific implementation

[0028] In order to make the personnel in the technical field better understand the utility model scheme, the technical scheme in the utility model embodiment will be described clearly and completely in conjunction with the drawings in the utility model embodiment below, obviously, the described embodiment is only a part of the embodiment of the utility model, not all. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor should belong to the protection scope of the utility model.

[0029] As described in the background, but the above-mentioned device clamping plate is a flat plate, and the shape and size of different engine supports are quite different, the above-mentioned device only relies on the clamping plate to clamp and fix the engine support, the clamping plate is in contact with the convex surface of the engine support, so that the engine support is unevenly stressed when clamped, thereby affecting the stability and fixing effect of the support.

[0030] In order to solve this technical problem, the utility model provides a kind of engine support bearing detection device, it is applied to engine support bearing detection.

[0031] Specifically, please refer to Figures 1-4 , engine support bearing detection device specifically includes:

[0032] The device base 1 has a support shell 2 fixedly connected to its top. A hydraulic cylinder body 3 is fixedly installed on the support shell 2. A pressure sensor body 4 is fixedly installed at the output end of the hydraulic cylinder body 3. A pressure plate 5 is fixedly installed at the bottom end of the pressure sensor body 4. The pressure plate 5 is slidably connected to the inner wall of the support shell 2. A receiving platform 6 is slidably connected to the top of the device base 1. A clamping mechanism 7 is provided on the receiving platform 6. Two adjustment mechanisms 8 are provided on the inner wall of the receiving platform 6. An engine bracket body 9 is placed on the receiving platform 6.

[0033] The clamping mechanism 7 includes a rotating shaft 10, a bidirectional threaded rod 11, a transmission assembly, a moving assembly, and a replacement assembly. The rotating shaft 10 is rotatably connected to the inner wall of the receiving platform 6, and the bidirectional threaded rod 11 is rotatably connected to the inner wall of the receiving platform 6.

[0034] The hydraulic cylinder body 3 and the pressure sensor body 4 in this application have the same specific structure and working principle as the hydraulic cylinder and pressure sensor in the prior art mentioned in the background of this application.

[0035] The engine mount load-bearing detection device provided by this utility model selects two clamping plates 23 that are compatible with the engine mount body 9 to be clamped and tested. The two clamping plates 23 are then installed onto two fixed housings 16, and the engine mount body 9 is placed between the two clamping plates 23. Rotating the rotating shaft 10 causes the two moving plates 15, carrying the corresponding clamping plates 23, to move closer together, thereby clamping and fixing the engine mount body 9. By installing clamping plates 23 that are compatible with the shape of different engine mount bodies 9, the engine mount body 9 is clamped, thus... The clamping plate 23 is matched with the concave and convex surfaces of the engine mount body 9, ensuring that the force applied to the engine mount body 9 is uniform, thereby ensuring the stability of the clamping restriction on the engine mount body 9. At the same time, since the clamping plate 23 is matched with the engine mount body 9, unnecessary damage or indentation to the surface of the engine mount body 9 is reduced during the clamping process. The installation and removal of the clamping plate 23 are also more convenient, improving the efficiency of the operator in changing the clamping plate 23 to match the engine mount body 9 to be tested, and improving the practicality of the device.

[0036] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0037] Example 1:

[0038] Please refer to Figures 2-6 An engine bracket load-bearing detection device, comprising:

[0039] The transmission assembly includes a first bevel gear 12. The first bevel gear 12 is fixedly connected to one end of the rotating shaft 10 located inside the receiving platform 6. A second bevel gear 13 is fixedly connected to the outer wall of the bidirectional threaded rod 11. The first bevel gear 12 meshes with the outer wall of the second bevel gear 13. Two friction discs 14 are fixedly connected to the outer wall of the bidirectional threaded rod 11. After the operator rotates the rotating shaft 10, the bidirectional threaded rod 11 can be rotated through the transmission assembly. The friction between the friction discs 14 and the receiving platform 6 can reduce the accidental rotation of the bidirectional threaded rod 11, thereby reducing the accidental movement of the two moving plates 15, so as to ensure the stability of clamping the engine bracket body 9.

[0040] The movable component includes a movable plate 15, and the outer wall of the bidirectional threaded rod 11 is threaded with movable plates 15 on both sides of the middle. Both movable plates 15 are slidably connected to the inner wall of the receiving platform 6. The distance between the two movable plates 15 can be adjusted to facilitate the operator to install or remove the clamping plate 23 and clamp the engine bracket body 9.

[0041] The replacement component includes a fixed housing 16. Two movable plates 15 are respectively fixedly connected to the fixed housing 16 on their adjacent sides. A pull rod 17 is slidably connected to the inner wall of each fixed housing 16. A disc 19 is fixedly connected to the bottom end of the pull rod 17, and the disc 19 is slidably connected to the inner wall of the fixed housing 16. A connecting plate 18 is fixedly connected to the top end of the pull rod 17. A first spring 20 is sleeved on the outside of the pull rod 17. The two ends of the first spring 20 are respectively fixedly connected to the outer wall of the disc 19 and the inner wall of the fixed housing 16. A plug rod 21 is fixedly connected to the bottom of the connecting plate 18, and the plug rod 21 is slidably connected to the inner wall of the fixed housing 16. The fixed housing 16 has a movable inner wall. The mounting block 22 is movably inserted, and the insertion rod 21 is movably inserted into the mounting block 22. The outer wall of the mounting block 22 is fixedly connected to a clamping plate 23 that is adapted to the engine bracket body 9. The clamping plate 23 can be molded to fit the shape of the engine bracket body 9 to be tested. The mounting block 22 is fixedly connected to each clamping plate 23. By pulling the connecting plate 18 to the bottom end of the insertion rod 21 and retracting it into the fixing shell 16, the mounting block 22 can be inserted into the fixing shell 16. After releasing the connecting plate 18, the installation of the clamping plate 23 is completed. This process is relatively simple and improves the convenience of the operator in installing the clamping plate 23.

[0042] Through the above structural design, by selecting two clamping plates 23 that are compatible with the engine bracket body 9 to be clamped and tested, and pulling the connecting plate 18 to the bottom end of the insertion rod 21 and retracting it into the fixed shell 16, the disc 19 and the pull rod 17 slide inside the fixed shell 16. The first spring 20 deforms accordingly, allowing the mounting block 22 to be inserted into the fixed shell 16. When the connecting plate 18 is released, the disc 19 moves downward under the elastic force of the first spring 20, and the insertion rod 21 slides downward through the pull rod 17 and the connecting plate 18, thus inserting the insertion rod 21 into the mounting block 22, completing the installation of the clamping plate 23. The engine bracket body 9 is then placed between the two clamping plates 23. After that, rotating the rotating shaft 10 drives the second bevel gear 13 to rotate through the first bevel gear 12, thereby causing the bidirectional threaded rod 11 to rotate, causing the friction disc 14 to rotate inside the receiving platform 6, thus causing the two... The movable plates 15, each carrying a corresponding clamping plate 23, move closer together to clamp and fix the engine mount body 9. Then, the switch of the hydraulic cylinder body 3 is turned on, driving the power source of the hydraulic pump. The hydraulic pump presses hydraulic oil into the switch of the hydraulic cylinder body 3, and the hydraulic cylinder body 3 pushes the pressure plate 5 to press down on the engine mount body 9 to bear the load. The pressure sensor body 4 above the pressure plate 5 detects the pressure on the engine mount body 9. When the detected load reaches the standard load value, the hydraulic cylinder body 3 raises the pressure plate 5 to the initial position. Then, the rotating shaft 10 can be rotated in the opposite direction to drive the bidirectional threaded rod 11 to rotate in the opposite direction, thereby moving the two movable plates 15 away from each other, so that the engine mount body 9 can be removed. When it is necessary to remove the clamping plate 23 later, simply pull the connecting plate 18 upward to the bottom end of the insertion rod 21 and retract it into the fixing shell 16 to pull out the clamping plate 23 and the mounting block 22 from the fixing shell 16.

[0043] Example 2:

[0044] The engine bracket load-bearing detection device provided in Example 1 has been further optimized, specifically, as follows: Figures 2-4 As shown, the adjustment mechanism 8 includes a rotating rod 24. The rotating rod 24 is rotatably connected to the inner wall of the receiving platform 6. A gear ring 25 is fixedly connected to the outer wall of the rotating rod 24. A rack 26 is slidably connected to the inner wall of the receiving platform 6. The rack 26 meshes with the outer wall of the gear ring 25. The rack 26 is movably inserted into the support shell 2. A handle is fixedly connected to one end of the rotating rod 24 located outside the receiving platform 6 to facilitate rotating and pulling the rotating rod 24.

[0045] The adjustment mechanism 8 also includes a second spring 27. The outer wall of the rack 26 is fixedly connected to the second spring 27. The end of the second spring 27 away from the rack 26 is fixedly connected to the inner wall of the receiving platform 6. The second spring 27 causes the rack 26 to have a tendency to move outward from the receiving platform 6. Multiple holes adapted to the rack 26 are opened on the support shell 2, corresponding to the positions of the rack 26 when the receiving platform 6 is below the pressure plate 5 and when it is away from the pressure plate 5.

[0046] With the above structural design, by holding the two rotating rods 24 and rotating both of them by a certain angle, the rack 26 is retracted into the receiving platform 6, causing the second spring 27 to deform. Then, the constraint between the receiving platform 6 and the support shell 2 can be released. Then, the rotating rods 24 can be pulled to make the receiving platform 6 slide on the device base 1. After the receiving platform 6 is slid to a suitable position away from the pressure plate 5, the two rotating rods 24 can be released, so that the rack 26 is inserted into the support shell 2 under the action of the second spring 27. Then, the engine bracket body 9 on the receiving platform 6 can be disassembled or installed.
