Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic presses, specifically to a positioning platform for hydraulic presses. Background Technology

[0002] When performing pressure tests or molding operations, hydraulic presses typically require placing containers or test samples on their platforms.

[0003] However, most existing hydraulic press platforms adopt a planar structure, and the pressurized containers are generally placed directly on the platform surface for pressure operation. Since the platform lacks a dedicated limiting or positioning mechanism, the containers are often placed and adjusted manually by visual inspection, resulting in low positioning accuracy.

[0004] During the operation of a hydraulic press, the vibration or reaction force generated by pressurization can easily cause the container to shift or tilt, affecting the stability of the pressure direction and thus causing uneven force distribution or experimental errors. Utility Model Content

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning platform for a hydraulic press, comprising a hydraulic press body, wherein an operating table is provided inside the hydraulic press body; The top of the operating table is provided with a fixing component, which includes four fixing plates. The four fixing plates are symmetrically arranged on the upper surface of the operating table, and connecting blocks are inserted between the four fixing plates. The fixed plate is provided with a buffer assembly, which includes a groove. The groove is formed inside the fixed plate, and a spring is fixedly connected to the inner top of the groove. A buffer rod is fixedly connected to the top of the spring.

[0007] Preferably, the fixing plate is constructed as an outer square and inner circle structure, wherein the inner side of the fixing plate is annular for circumferentially limiting and centering the pressure vessel, and the outer side of the fixing plate is provided with a square groove.

[0008] Preferably, an extension plate is fixedly connected to one side of the connecting block.

[0009] Preferably, the four fixing plates are arranged in a centrally symmetrical manner with respect to the center of the operating table.

[0010] Preferably, the connecting block is symmetrically fixedly connected to both sides of the connecting block, and each of the fixed plates has a symmetrically opened fixing groove on one side of each adjacent side, and the outside of the fixing block is inserted into the inside of the fixing groove.

[0012] Preferably, a positioning rod is fixedly connected to the bottom of the fixing plate, and four positioning slots are provided on the top of the operating table.

[0013] Compared with the prior art, this utility model forms a rectangular closed frame by setting four plug-in fixing plates on the top of the operating table, and arranges buffer components inside the fixing plates to achieve stable support and pressure impact absorption for the pressurized container.

[0016] 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.

[0017] Please see Figure 1 An embodiment of this utility model provides a positioning platform for a hydraulic press, including a hydraulic press body 10, and an operating table 11 is provided inside the hydraulic press body 10.

[0018] A fixing component 20 is provided on the top of the operating table 11. The fixing component 20 includes four fixing plates 21, which are symmetrically arranged on the upper surface of the operating table 11. Connecting blocks 23 are inserted between the four fixing plates 21. According to the above technical solution, by setting an operating platform 11 on the hydraulic press body 10 and arranging a fixing component 20 on the top of the operating platform 11, the pressurization area of ​​the hydraulic press forms a relatively independent bearing and positioning space. Four fixing plates 21 are distributed along the four corners of the operating platform 11 and are connected to each other by connecting blocks 23, so that the operating platform 11 forms a closed rectangular frame structure, making the load more evenly distributed on the surface of the operating platform 11. The reaction force under pressure is borne by the four fixing plates 21 together, forming a stable support system.

[0019] like Figure 2 As shown, a buffer assembly 30 is provided inside the fixed plate 21. The buffer assembly 30 includes a groove 31, which is opened inside the fixed plate 21. A spring 33 is fixedly connected to the inner top of the groove 31, and a buffer rod 32 is fixedly connected to the top of the spring 33.

[0020] According to the above technical solution, when the hydraulic press is working, the bottom of the pressure container contacts the buffer rod 32, and the external pressure is transmitted downward to the spring 33 through the buffer rod 32. The spring 33 absorbs the instantaneous impact load during the compression process, and the groove 31 provides movement space for the elastic deformation of the spring 33.

[0021] This structure allows the platform to respond flexibly under pressure, making the load transmitted to the operating table 11 more gradual, preventing high-frequency vibrations from accumulating between the operating table 11 and the hydraulic press body 10, and maintaining the stability of the assembly gaps and relative positions between the components.

[0022] In one embodiment, the fixing plate 21 is constructed as an outer square and inner circle structure, wherein the inner side of the fixing plate 21 is annular for circumferentially limiting and centering the pressure vessel, and the outer side of the fixing plate 21 is provided with a square groove 34.

[0023] According to the above technical solution, the fixing plate 21 adopts a structure of outer square and inner circle, wherein the inner ring area matches the bottom of the pressure container, which can automatically generate a circumferential limiting effect when placed, so that the bottom of the container is supported along the circular edge and maintains a concentric position.

[0024] The outer edge of the fixing plate 21 is square, and a square groove 34 is opened on the outside. The square groove 34 provides an embedding space for the installation of the buffer component 30 and the fixing block 24. At the same time, it forms a reinforcing rib area in the structure, so that the fixing plate 21 is not easy to deform when subjected to longitudinal pressure. The combination of the inner ring and the outer square not only ensures the circular fit of the container, but also maintains the overall support strength of the platform under the square shape, realizing the stability of the structure and the standardization of assembly.

[0025] In one embodiment, an extension plate 25 is fixedly connected to one side of the connecting block 23.

[0026] According to the above technical solution, an extension plate 25 is provided on one side of the connecting block 23 so that the outer edge of the fixing component 20 can be spliced ​​and connected with the operating table 11 or other extension parts. The extension plate 25 is integrally formed with the connecting block 23 and is inserted between adjacent fixing plates 21. This can increase the length of the connection surface, limit the lateral displacement of the fixing plate 21, and bear part of the tensile or shear force when the compressive load changes. Through this structure, the overall fit of the platform is enhanced, and the four fixing plates 21 form a closed loop fit, so that the platform maintains the consistency of geometric shape during the stress process.

[0027] In one embodiment, the four fixed plates 21 are arranged in a centrally symmetrical manner with respect to the center of the operating table 11.

[0028] According to the above technical solution, the four fixed plates 21 are arranged symmetrically with the center of the operating platform 11 as the symmetrical point, and the angle between each plate is 90°. This centrally symmetrical layout makes the reaction force path of the platform uniform when under pressure, avoids stress concentration on one side, and can maintain the overall geometric symmetry when the pressure vessel is placed in the center. At the same time, the symmetrical arrangement is also convenient for processing and assembly, and each plate can be manufactured with the same specifications to achieve structural universality.

[0029] In one embodiment, fixing blocks 24 are symmetrically fixedly connected to both sides of the connecting block 23, and fixing slots 22 are symmetrically opened on the adjacent side of each fixing plate 21, with the outside of the fixing block 24 inserted into the inside of the fixing slot 22.

[0030] According to the above technical solution, the plug-in connection ensures the relative position between adjacent fixing plates 21. The plug-in connection generates an inward limiting effect, preventing the fixing plates 21 from sliding relative to each other under vibration or reaction force. This makes the fixing assembly 20 have an integral feature after installation, and the platform maintains geometric stability during operation, ensuring the accurate position of each limiting component.

[0031] In one embodiment, the interior of the connecting block 23 is constructed as an arc-shaped structure, which is connected to the four fixing plates 21 to form a circular structure.

[0032] According to the above technical solution, the arc connection forms a smooth transition interface between the inner edges of each fixing plate 21, so that the pressure vessel can naturally fit against the circular interface when placed, reducing corner interference. At the same time, it helps to disperse the circumferential load and uniformly transfer the local force to the adjacent fixing plates 21 during the pressure process, thereby improving the force consistency of the entire circular limiting area.

[0033] In one embodiment, such as Figure 3As shown, a positioning rod 27 is fixedly connected to the bottom of the fixed plate 21, and four positioning slots 26 are provided on the top of the operating table 11.

[0034] According to the above technical solution, when the fixing plate 21 is installed on the operating table 11, the positioning rod 27 can be inserted into the positioning groove 26. The spatial constraint between the fixing plate 21 and the operating table 11 is achieved through the insertion and cooperation. The positioning rod 27 is arranged vertically, which can limit the translational displacement of the fixing plate 21 in the horizontal direction, and at the same time prevent the fixing plate 21 from rotating and shifting under the action of external force or reaction force. The positioning groove 26 provides a precise installation position for the fixing plate 21, so that the four fixing plates 21 can automatically align with the geometric center of the operating table 11 during assembly, thereby ensuring that the positioning assembly as a whole is symmetrically arranged.

[0035] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
