Description

Technical Field

[0001] The utility model relates to the technical field of pressing equipment, in particular to a linear pressure control mechanism. Background Art

[0002] When assembling or welding two materials, precise pressure is required to press them together. The required pressure varies depending on the material specifications, and therefore the required pressure also varies. Existing pressure mechanisms typically have their own pressure, and when used in conjunction with a downward pressure mechanism, pressure control is often inaccurate. This not only results in insufficient precision in pressing the materials together, but also fails to meet user requirements for pressing materials of varying specifications. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a linear pressure control mechanism, which not only realizes its own force balance and does not carry its own pressure, but also cooperates with the downward pressure mechanism disk to provide stable linear pressure, while meeting the pressing requirements of materials of different specifications.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a linear pressure control mechanism, including a main body bracket, a balancing component, a pressure sensor and a pressure head, and connecting plates are provided at both ends of the pressure head. The two ends of the main body bracket are slidably connected to the connecting plates through a sliding component, and the main body bracket can move up and down along the connecting plates.

[0005] The balancing assembly includes a compression spring and a tension spring, one end of the compression spring is connected to the top of the main bracket, the other end of the compression spring is connected to the pressure sensor, the pressure sensor is connected to the pressure head, one end of the tension spring is connected to the top side end of the main bracket, the other end of the tension spring is connected to the end of the compression spring close to the pressure sensor through a connecting ring, and the tension spring is located on one side of the compression spring.

[0006] In one embodiment, the tension of the extension spring of the linear pressure control mechanism=the elastic force of the compression spring+the weight of the pressure head.

[0007] In one embodiment, the pressure sensor and the pressure head of the linear pressure control mechanism are connected by a bolt assembly, which includes a bolt and a nut. The pressure sensor is connected to the bolt, and the bolt passes through the nut and is threadedly connected to the pressure head, and the nut fixes the bolt.

[0008] In one embodiment, the sliding assembly of the linear pressure control mechanism includes a linear guide rail and a slider. The linear guide rail is vertically installed on the side end of the main bracket, and the slider is installed on the inner side of the connecting plate. The slider slides with the linear guide rail.

[0009] In one embodiment, the connecting ring of the linear pressure control mechanism includes a fixed block and a fixed ring, the fixed block is connected to the fixed ring, the fixed ring is fixedly sleeved on the bottom end of the compression spring, and the fixed block is connected to one end of the tension spring.

[0010] The beneficial effects of this application are:

[0011] This application provides a linear pressure control mechanism that achieves self-balancing force by providing a balancing component that works with the pressure head, pressure sensor, and main frame. This linear pressure control mechanism not only does not generate its own pressure but also works with the downward pressure mechanism to achieve precise pressing of materials, providing stable linear pressure and meeting the pressing requirements of materials of different specifications.

[0012] The linear pressure control mechanism uses a tension spring and a compression spring in combination, so that the tension of the tension spring is equal to the elastic force of the compression spring plus the gravity of the pressure head, realizing the self-force balance of the mechanism and meeting the precise pressure control of the material.

[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 As shown, an embodiment of the present application provides a linear pressure control mechanism, including a main support 1, a balancing component 2, a pressure sensor 3 and a pressure head 4, and connecting plates 5 are provided at both ends of the pressure head 4. The two ends of the main support 1 are slidingly connected to the connecting plate 5 through a sliding component 6, and the main support 1 can move up and down along the connecting plate 5.

[0020] like Figure 2 As shown, the balancing assembly 2 includes a compression spring 21 and a tension spring 22. One end of the compression spring 21 is connected to the top of the main bracket 1, and the other end of the compression spring 21 is connected to the pressure sensor 3. The pressure sensor 3 is connected to the pressure head 4. One end of the tension spring 22 is connected to the top side end of the main bracket 1, and the other end of the tension spring 22 is connected to the end of the compression spring 21 close to the pressure sensor 3 through a connecting ring 23. The tension spring 22 is located on one side of the compression spring 21.

[0021] Specifically, the main frame 1 and the pressure head 4 are connected via two connecting plates 5, with both ends of the main frame 1 slidingly engaged with the connecting plates 5. One end of the pressure sensor 3 is connected to the top of the main frame 1 via a compression spring 21, and the pressure sensor 3 and the pressure head 4 are connected via a bolt assembly. One end of the tension spring 22 is connected to the top side of the main frame 1, and the other end of the tension spring 22 is connected to the compression spring 21 via a connecting ring 23. The tension spring 22 is located outside the compression spring 21. Based on the required elastic coefficient and Z-axis height, the appropriate tension spring 22 and compression spring 21 are selected so that the tension of the tension spring 22 is equal to the sum of the elastic force of the compression spring 21 and the weight of the pressure head 4, ensuring the force balance of the mechanism itself.

[0022] Connect the main support 1 of the linear pressure control mechanism to the Z-axis downward pressure mechanism. The Z-axis downward pressure mechanism can drive the main support 1 to move the pressure head 4 up and down. When the material is pressed, the connecting plates 5 at both ends of the pressure head 4 move upward along the main support 1. At the same time, the pressure sensor 3 is forced upward to compress the compression spring 21 and tension spring 22, thereby obtaining the pressure detection result. The downward pressure mechanism drives the linear pressure control mechanism to press downward. The linear pressure control mechanism starts to apply pressure to the material from zero. During the downward pressure process, it provides stable linear pressure to prevent the pressure from zero to exceed the force of its own weight.

[0023] In the above structure, the balancing assembly 2, in conjunction with the main support 1, pressure sensor 3, and pressure head 4, achieves self-balancing force within the mechanism, enabling precise pressure control of the material. When the pressing mechanism drives the linear pressure control mechanism downward, a stable linear pressure output is generated starting from zero pressure, meeting various production requirements for pressing and pressure-maintaining mechanisms.

[0024] like Figure 1 As shown, in one embodiment, the tension of the tension spring 22 of the linear pressure control mechanism equals the elastic force of the compression spring 21 + the weight of the pressure head 4. Based on the calculation of the spring elastic coefficient and the Z-axis height design requirements, the appropriate tension spring 22 and compression spring 21 are selected to ensure that, at a specific Z-axis position, the tension of the tension spring 22 is equal to the sum of the elastic force of the compression spring 21 and the weight of the pressure head 4, achieving the mechanism's own force balance and ensuring precise pressure control of the material.

[0025] like Figure 3 As shown, in one embodiment, the pressure sensor 3 and the pressure head 4 of the linear pressure control mechanism are connected by a bolt assembly comprising a bolt 31 and a nut 32. The pressure sensor 3 is connected to the bolt 31, which is threaded through the nut 32 and connected to the pressure head 4. The nut 32 secures the bolt 31. The bolt 31 on the pressure sensor 3 is threaded through the nut 32 and connected to the pressure head 4. When rotated to the appropriate position, the bolt 31 is tightened by the nut 32. When the pressure head 4 is subjected to force, the pressure sensor 3 detects pressure. This arrangement facilitates the securement of the pressure head 4 and the pressure sensor 3.

[0026] like Figure 2 As shown in one embodiment, the sliding assembly 6 of the linear pressure control mechanism includes a linear guide 61 and a slider 62. The linear guide 61 is vertically mounted on the side of the main frame 1, and the slider 62 is mounted on the inner side of the connecting plate 5. The slider 62 slides in engagement with the linear guide 61. When the ram 4 is subjected to force, the slider 62 of the connecting plate 5 moves up and down along the linear guide 61 of the main frame 1. This arrangement facilitates micro-movement of the ram 4 under force.

[0027] like Figure 2 and Figure 3 As shown, in one embodiment, the connecting ring 23 of the linear pressure control mechanism includes a fixing block 231 and a fixing ring 232. The fixing block 231 is connected to the fixing ring 232. The fixing ring 232 is fixedly mounted on the bottom end of the compression spring 21. The fixing block 231 is connected to one end of the tension spring 22. This arrangement facilitates the tension spring 22 to exert a certain pulling force on the pressure sensor 3 and the pressure head 4.

[0028] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
