Description

Technical Field

[0001] This utility model relates to a constant pressure application mechanism and application device, belonging to the technical field of pressurization equipment. Background Technology

[0002] In processes such as material forming, component assembly, and pressure testing, it is often necessary to apply constant pressure to an object to meet specific requirements. Common methods of applying pressure include:

[0003] 1. Pressure is applied using fixed counterweights, and the pressure is adjusted by increasing or decreasing the number of counterweights or replacing them with counterweights of different weights. This method is difficult to adjust the pressure precisely and is cumbersome to operate.

[0004] 2. Applying pressure using pneumatic or hydraulic cylinders. This method requires complex air and hydraulic sources and corresponding control systems, resulting in complex structures, high costs, and maintenance issues such as air and oil leaks, thus limiting its effectiveness. In the prior art, Chinese invention patent application publication number CN105500242A discloses a pressure clamp for constant force application to copper sheet bonding assemblies. Its technical solution is as follows: by rotating the pressure handle, the pressure screw rotates, and the spring limiting plate at the lower end of the pressure screw applies pressure to the helical spring and pushes the helical spring downwards. The lower end of the helical spring pushes the movable pressure plate to slowly move downwards on the guide rod. The movable pressure plate's recessed groove converts the pressure into a uniformly applied force, which, in conjunction with the recessed groove of the lower connecting plate, applies pressure to the two force-bearing surfaces of the copper sheet bonding assembly, completing the uniform pressure application and holding of various parts of the copper sheet bonding assembly. This patent, by using components such as a pressure screw, helical spring, and movable pressure plate, can apply constant pressure with uniform and accurate pressure application. However, the structure of this patent has the following problems:

[0005] On the one hand, the structure in this patent is somewhat complex. On the other hand, when it is necessary to release the applied pressure, the helical spring and movable pressure plate in this patent are not stable enough due to the influence of their connection settings, which can easily affect the accuracy and stability of pressure adjustment during later use. Utility Model Content

[0006] The present invention aims to provide a constant pressure application mechanism and application device to solve the problems of complex structure and insufficient stability of existing devices, and to achieve precise and stable pressure regulation.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A constant pressure application mechanism includes a threaded rod, a bracket, an elastic element, and a pressure block; the threaded rod is threadedly connected to the bracket, the elastic element is disposed between the threaded rod and the pressure block, and the pressure block and the bracket form a sliding pair; one end of the threaded rod is provided with a connecting post, and the elastic element is sleeved on the connecting post; the pressure block has a channel and a receiving space communicating with the channel, the end of the connecting post passes through the channel and extends into the receiving space, and the receiving space is provided with a one-way stop that can rotate relative to the channel and move along the length direction of the connecting post, the one-way stop being connected to the end of the connecting post and used to prevent the end of the connecting post from retracting from the receiving space into the channel.

[0009] During operation, the object to be pressed is placed in a predetermined position under the pressure block. Since the threaded rod is threadedly connected to the support, rotating the threaded rod causes the connecting column to rotate as well, moving the threaded rod and connecting column along their axes. This compresses the elastic element. Under the reaction force of the elastic element, the pressure block slides relative to the support and applies pressure to the object. As the compression of the elastic element increases, the pressure gradually increases. When the desired pressure value is reached, rotating the threaded rod stops, allowing the mechanism to continuously and stably apply constant pressure to the object. When it is necessary to release the applied pressure, rotating the threaded rod in the opposite direction causes the connecting column to rotate in the same direction. Because a one-way stop is connected to the end of the connecting column, the pressure block is pulled out in the opposite direction along with the connecting column and threaded rod, thus releasing the object. This constant pressure application mechanism solves the problems of complex structure and insufficient stability in existing devices, achieving precise and stable pressure regulation.

[0010] Furthermore, in order to enhance the structural stability of the connection between the threaded rod and the bracket, a nut is provided on the threaded rod, and the nut is located on the side of the bracket away from the pressure block.

[0011] Furthermore, the bracket includes a main column and guide columns fixed at both ends of the main column. The threaded rod is threadedly connected to the main column. The pressure block is disposed between the two guide columns and forms a sliding pair with the guide columns. The nut is located on the side of the main column away from the pressure block.

[0012] Furthermore, to facilitate the rotation of the threaded rod, a screwing block is provided at the end of the threaded rod away from the connecting post.

[0013] Furthermore, to enhance structural stability, the diameter of the threaded rod is greater than the diameter of the elastic element and the diameter of the connecting post, and the elastic element is a spring.

[0014] Furthermore, in order to simplify the structure, reduce costs, and enhance stability, the threaded rod and the connecting post are integrally formed.

[0015] Furthermore, the threaded rod and the connecting post are combined to form a stepped rod-like structure.

[0016] Furthermore, in order to intuitively display the test results and facilitate pressure adjustment, a pressure sensor is provided between the elastic element and the pressure block. The pressure sensor is fixed to the pressure block and sleeved on the connecting column, and a digital display is connected to the pressure sensor.

[0017] Based on the same inventive concept, this utility model also provides a constant pressure application device. The constant pressure application device includes the above-mentioned constant pressure application mechanism and the object to be pressed; the pressure block is provided with a pressure application hole, and the object to be pressed is disposed in the pressure application hole.

[0018] During operation, the object to be pressed is placed in the pressure hole of the pressure block, and the above steps are repeated. In this way, the constant pressure application device solves the problems of complex structure and insufficient stability of existing devices, and realizes precise and stable pressure regulation.

[0019] Furthermore, in order to ensure that the pressure is evenly transmitted to the object being pressed while preventing damage or displacement to the surface of the object being pressed, a protective structure is provided inside the pressure hole, and the protective structure is disposed between the pressure hole and the object being pressed.

[0020] Compared with the prior art, this utility model has the following advantages:

[0021] 1. The constant pressure application mechanism of this utility model solves the problems of complex structure and insufficient stability of existing devices by setting a one-way stop and setting a connection structure for the elastic element, connecting column, pressure block and one-way stop, and realizes precise and stable pressure adjustment. It has the advantages of low cost, convenient operation and stable reliability.

[0022] 2. The constant pressure application mechanism of this utility model can continuously provide constant and reliable pressure, and is suitable for a variety of scenarios that require constant pressure, and has a wide range of application prospects.

[0023] 3.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Example 1

[0030] See Figures 1 to 3 This embodiment provides a constant pressure application mechanism for providing constant pressure. It features simple structure, low cost, convenient operation, and stable reliability, making it suitable for various scenarios requiring constant pressure and possessing broad application prospects. The constant pressure application mechanism includes a threaded rod 1, a connecting column 2, a bracket 3, an elastic element, a pressure block 5, and a one-way stop. The bracket 3 includes a main column 31 and guide columns 32 vertically fixed to both ends of the main column 31. The elastic element is a spring 4. The pressure block 5 has a channel 51 and a receiving space 52 communicating with the channel 51.

[0031] Both the threaded rod 1 and the connecting post 2 are round rods. The threaded rod 1 is threadedly connected to the main post 31. One end of the connecting post 2 is coaxially fixed to the end of the threaded rod 1, and the other end passes through the spring 4 and the channel 51 and extends into the receiving space 52; the connecting post 2 serves to support the installation of the spring 4 and prevent slippage and disengagement. Both the main post 31 and the guide post 32 are columnar structures, and the combined bracket 3 is U-shaped.

[0032] The spring 4 is selected according to the characteristics of the object being pressed 9 and the required pressure range. The spring 4 is located between the threaded rod 1 and the pressure block 5 and is sleeved on the connecting post 2; the end of the spring 4 can be fixed to the end of the threaded rod 1, which can enhance the structural stability. The diameter of the threaded rod 1 is larger than the diameter of the spring 4 and the diameter of the connecting post 2, which can limit the end of the spring 4, facilitate the application of uniform pressure to the spring 4, and enhance the structural stability.

[0033] The pressure block 5 has a circular hole 51 and a square hole 52 for receiving space. The pressure block 5 is positioned between two guide posts 32 and forms a sliding pair with them. Specifically, the pressure block 5 has grooves 53 at both ends, allowing it to slide smoothly through these grooves to the two guide posts 32. This enhances structural stability and improves overall stability. The shape and size of the pressure block 5 can be adjusted as needed.

[0034] A one-way stop is located within the receiving space 52, is rotatable relative to the channel 51, and can move along the length of the connecting post 2. The one-way stop is connected to the end of the connecting post 2 and prevents the end of the connecting post 2 from retracting from the receiving space 52 into the channel 51. The one-way stop can be a retaining ring 6, with a slot 21 formed at the end of the connecting post 2, into which the retaining ring 6 is snapped.

[0035] To enhance the structural stability of the connection between the threaded rod 1 and the main column 31, a nut 7 can be threaded onto the threaded rod 1. This nut 7 is located on the side of the main column 31 away from the pressure block 5. After the threaded rod 1 is tightened, the nut 7 can be turned closer to the end face of the main column 31. This increases the axial force on the threaded rod 1 due to the action of the spring 4, thereby increasing the friction between the threads of the threaded rod 1 and the threads of the main column 31, preventing the threaded rod 1 from easily loosening. The nut 7 serves to further enhance stability.

[0036] To facilitate the rotation of the threaded rod 1, a screwing block 8 is provided at the end of the threaded rod 1 furthest from the connecting post 2. The screwing block 8 is hexagonal in shape. To simplify the structure, reduce costs, and enhance stability, the threaded rod 1 and the connecting post 2 are integrally formed, combining to form a stepped rod-like structure. The screwing block 8, the threaded rod 1, and the connecting post 2 can be integrally installed. Through the threaded connection between the threaded rod 1 and the bracket 3, the sequential passage of the connecting post 2 through the spring 4 and the pressure block 5, and the movement of the pressure block 5 under the constraint of the sliding groove 53, it is ensured that the threaded rod 1 can stably perform linear motion during rotation, thereby precisely controlling the compression of the spring 4 and achieving precise pressure adjustment.

[0037] To visually display the test results and facilitate pressure adjustment, a pressure sensor can be installed between the elastic element and the pressure block 5. The pressure sensor is fixed to the end face of the pressure block 5 and sleeved on the connecting post 2, while an external digital display is connected to the pressure sensor. The pressure sensor can be a ring-shaped hollow force sensor.

[0038] Example 2

[0039] This embodiment provides an application of a constant pressure application mechanism: when performing a pressure test on an electronic component, the electronic component is placed under the pressure block 5, and the compression of the spring 4 is adjusted by rotating the threaded rod 1 so that the pressure block 5 applies a set constant pressure to the electronic component. At the same time, the value of the pressure monitoring component, such as a digital display, is observed to ensure the accuracy and stability of the pressure, thereby ensuring the accuracy of the test results.

[0040] Example 3

[0041] The difference between this embodiment and Embodiment 1 is that this embodiment provides a constant pressure application device. This constant pressure application device includes the constant pressure application mechanism from Embodiment 1, and the object to be pressed 9; simultaneously, a pressure hole 54 for placing the object to be pressed 9 is provided within the pressure block 5. During operation, the object to be pressed 9 is placed within the pressure hole 54 of the pressure block 5, and then pressure is applied.

[0042] The pressure hole 54 can be a round hole, which facilitates the application of pressure and enhances stability.

[0043] To ensure that pressure is evenly transmitted to the object being pressed 9 while preventing damage or displacement to the surface of the object being pressed 9, a protective structure can be provided inside the pressure hole 54, with the protective structure positioned between the pressure hole 54 and the object being pressed 9. For example, when the object being pressed 9 is a shaft, the protective structure can be a bearing.
