Description

Technical Field

[0001] This utility model relates to the field of press technology, and in particular to a press with assembly positioning. Background Technology

[0002] Traditional presses suffer from technical problems such as insufficient positioning accuracy, poor structural stability, and low automation during the pressure assembly of parts. Specifically: First, workpiece positioning relies heavily on manual clamping or simple mechanical structures, making high-precision centering difficult. Misalignment or tilting easily occurs during pressurization, leading to unstable assembly quality, especially with circular or symmetrical workpieces. Existing presses lack automatic positioning mechanisms linked to the hydraulic system; clamping force adjustment depends on manual experience and cannot be dynamically adjusted according to workpiece material or precision requirements. Excessive clamping force can damage the workpiece, while insufficient force can cause positioning failure. Furthermore, clamping and releasing actions require multiple steps, and the reset mechanism has low reliability, increasing manual intervention and production cycle time, making it difficult to meet the high-efficiency, continuous operation requirements of automated production lines. Therefore, a press with assembly positioning capabilities is needed. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4 A press with assembly positioning includes a base plate 1, two base plates 1 are arranged in parallel, and a column 2 is connected to the inner side of the base plate 1 by screw thread. The surface of the column 2 is provided with a socket hole 3. Multiple socket holes 3 are linearly arranged in the vertical direction. A mounting plug screw 4 is movably sleeved on the inner wall of every two opposite socket holes 3. A locking nut 5 is threaded to one end of the mounting plug screw 4. A supporting base plate 13 is sleeved on the surface of the mounting plug screw 4.

[0021] A connecting support plate 7 is fixedly installed between the two columns 2. A top plate 8 is fixedly installed on the top of each of the four columns 2, and a hydraulic cylinder 9 is installed in the middle of the top plate 8. A hydraulic pump 10 is fixedly installed on the side of each of the two columns 2 on the left. The side of the hydraulic pump 10 is connected to the surface of the hydraulic cylinder 9 through oil pipes. A motor mounting plate 11 is fixedly installed on the top of the hydraulic pump 10, and a motor 12 is fixedly installed on the surface of the motor mounting plate 11. The operation of the motor 12 converts the mechanical kinetic energy of the motor 12 into hydraulic driving energy, thereby realizing the action of delivering hydraulic oil to the hydraulic cylinder 9.

[0022] Specifically, the press uses a motor 12 to drive a hydraulic pump 10, converting mechanical energy into hydraulic energy. High-pressure oil is then delivered to the hydraulic cylinder 9 via oil pipes, pushing the piston 68 downwards and applying pressure to the workpiece placed on the support plate 13. The hydraulic system features stable pressure, high force, and controllable speed. The connecting support plate 7 enhances the rigidity between the columns 2, while the top plate 8 serves as the mounting base for the hydraulic cylinder 9, ensuring stable and reliable pressure transmission throughout the process. The overall structure forms a closed-loop power and execution system: motor 12 - hydraulic pump 10 - hydraulic cylinder 9 - workpiece.

[0023] This device significantly improves the performance and practicality of the press through the organic integration of a hydraulic system and a rigid frame. First, the motor 12 drives the hydraulic pump 10 to achieve efficient energy conversion, providing a stable and adjustable high-pressure output to meet the processing needs of different workpieces, and features overload protection to enhance safety. Second, the placement of the top plate 8 and the connecting support plate 7 greatly enhances the rigidity and stability of the overall structure, reducing deformation under pressure and ensuring processing accuracy. The centrally mounted hydraulic cylinder 9 ensures even pressure distribution, preventing equipment damage caused by uneven loading.

[0024] An assembly positioning mechanism 6 is provided on the top of the support base plate 13. The assembly positioning mechanism 6 realizes the assembly and positioning of parts during pressure assembly. The assembly positioning mechanism 6 includes an assembly positioning plate 61, which is installed on the top of the support base plate 13. A clamping groove 62 is provided on the top of the assembly positioning plate 61, and an annular drive cavity 63 is provided on the bottom of the assembly positioning plate 61.

[0025] Specifically, the design of the clamping slot 62 enables rapid and stable initial positioning, effectively preventing workpiece displacement or tilting during pressurization and ensuring assembly quality. Secondly, the introduction of the annular drive cavity 63 gives the positioning mechanism automated adjustment capabilities, allowing it to be linked with an external drive system to automatically clamp, release, or adjust the angle of the workpiece, reducing manual intervention and labor intensity.

[0026] An oil inlet pipe 64 is installed on one side surface of the assembly positioning plate 61. One end of the oil inlet pipe 64 is fixedly connected to the inner wall of the annular drive cavity 63. A valve 65 is provided on the surface of the oil inlet pipe 64. The oil inlet end of the oil inlet pipe 64 is connected to the discharge end of the oil pump.

[0027] Specifically, this is achieved through valve 65 control, which allows for precise adjustment of the clamping force. This ensures stable workpiece positioning while preventing damage due to excessive pressure, adapting to assembly requirements of different materials and precision levels. Secondly, the hydraulic drive offers fast response and smooth operation, significantly improving assembly efficiency and reducing manual adjustment time. Furthermore, the integrated design of the oil inlet pipe 64 and the oil pump links the positioning mechanism with the main hydraulic system, simplifying piping layout and reducing equipment complexity.

[0028] The oil inlet pipe 64 introduces high-pressure oil from the oil pump into the annular drive chamber 63 at the bottom of the assembly positioning plate 61. The valve 65 controls the on / off state and flow rate of the oil circuit. When valve 65 is open, hydraulic oil enters the annular drive chamber 63, driving the internal drive structure to move, thereby clamping, releasing, or adjusting the position of the workpiece in the clamping slot 62. By adjusting valve 65, the pressure and flow rate of the hydraulic oil can be precisely controlled, thereby adjusting the clamping force and action speed, forming a controllable hydraulic drive positioning system.

[0029] The top of the assembly positioning plate 61 has a ring array of rectangular driving cavities 66. The inner bottom walls of the four rectangular driving cavities 66 are fixedly connected to the inner wall of the ring driving cavity 63. A clamping rod 67 is slidably inserted into one side surface of the rectangular driving cavity 66. The opposite ends of the four clamping rods 67 are all arc-shaped.

[0030] Specifically, this is implemented by assembling a positioning plate 61 with four rectangular drive cavities 66 arranged in a ring array on the top, which are connected to a ring drive cavity 63 at the bottom, forming a hydraulic linkage structure. When high-pressure oil enters the ring drive cavity 63 through the oil inlet pipe 64, the hydraulic oil is synchronously distributed to the four rectangular drive cavities 66, pushing the clamping rod 67 to slide outward. Since one end of the clamping rod 67 is arc-shaped, the four rods can evenly clamp the workpiece from all sides when moving outward, forming a centrally symmetrical clamping force. This structure utilizes hydraulic synchronous drive and mechanical guidance to achieve rapid, accurate, and uniform clamping and positioning of the workpiece.

[0031] The four clamping rods 67 move synchronously, ensuring a uniform distribution of clamping force and preventing workpiece displacement or deformation due to uneven force. This is particularly suitable for high-precision assembly of circular or symmetrical workpieces. Secondly, the rounded ends of the clamping rods 67 increase the contact area with the workpiece, reducing localized stress concentration, effectively protecting the workpiece surface, and improving assembly quality. Furthermore, the synchronous hydraulic drive allows for rapid and adjustable clamping actions, adapting to the flexible production needs of workpieces of different sizes. The compact overall structure and rapid response not only improve assembly efficiency but also enhance the equipment's adaptability to complex workpieces, providing an efficient and reliable positioning solution for automated production lines.

[0032] A piston 68 is fixedly installed at the other end of the clamping rod 67. The piston 68 is located inside the rectangular drive cavity 66. The four sides of the piston 68 are slidably inserted into the inner wall of the rectangular drive cavity 66 through sealing rings. A spring 69 is fixedly installed on the other side of the piston 68. The two springs 69 are located on both sides of the clamping rod 67, and the other ends of the two springs 69 are in contact with the inner sidewall of the rectangular drive cavity 66.

[0033] Specifically, the clamping rod 67 is hydraulically driven and mechanically reset within the rectangular drive chamber 66 via the piston 68. When hydraulic oil enters the rectangular drive chamber 66, it pushes the piston 68 to slide outward, causing the clamping rod 67 to extend and clamp the workpiece. When the hydraulic oil is depressurized, the preload of the springs 69 on both sides pushes the piston 68 to reset, causing the clamping rod 67 to automatically release the workpiece. The sealing rings around the piston 68 ensure that the hydraulic oil does not leak, maintaining stable system pressure. The symmetrical arrangement of the springs 69 ensures the smoothness and centering of the clamping rod 67 during the reset process, forming a closed-loop control mechanism of "hydraulic drive clamping - spring 69 reset and release".

[0034] The combination of piston 68 and sealing ring ensures the sealing of the hydraulic drive, preventing oil leakage, maintaining stable system pressure, and guaranteeing precise control of clamping force. Secondly, the symmetrical arrangement of springs 69 on both sides enables rapid and smooth reset of the clamping rod 67, completing the release action without an additional power source, simplifying the control system and reducing energy consumption. Furthermore, the preload of springs 69 provides an initial positioning function, preventing the clamping rod 67 from loosening when not in operation, thus improving equipment safety. The overall structure combines efficient clamping and automatic reset capabilities, making it particularly suitable for automated assembly scenarios with frequent start-stop cycles, significantly improving production efficiency and equipment lifespan.

[0035] This press achieves efficient, precise, and safe pressure assembly operations through structural innovation and system integration. Firstly, the modular column 2 and adjustable design provide high flexibility, adapting to the processing needs of workpieces of different sizes. The hydraulic system provides a stable and adjustable high-pressure output, while the rigid frame ensures uniform pressure transmission, preventing deformation and improving processing accuracy. Secondly, the assembly positioning mechanism 6, through a hydraulically synchronized four-way clamping rod 67 and spring 69 reset mechanism, achieves rapid and precise workpiece positioning and automatic release, reducing manual intervention and improving assembly efficiency and consistency. The sealing ring and valve 65 ensure system sealing and pressure controllability, preventing workpiece damage and oil leakage. The overall design combines high rigidity, high precision, high automation, and high safety, making it particularly suitable for mass production and precision assembly scenarios, significantly improving production efficiency and product quality.

[0036] Working principle: Clamping preparation: The workpiece is placed in the clamping slot 62 of the assembly positioning plate 61 for initial positioning. The ends of the four clamping rods 67 are arc-shaped, which can fit against the surface of the workpiece to achieve multi-point contact clamping.

[0037] Hydraulic clamping: High-pressure oil output from the oil pump enters the annular drive chamber 63 through the oil inlet pipe 64, and then flows into four rectangular drive chambers 66. The oil pressure pushes the piston 68 to slide within the rectangular drive chambers 66, driving the clamping rod 67 to move outward and clamp the workpiece. The piston 68 is equipped with sealing rings to ensure that the oil does not leak and to maintain stable pressure.

[0038] Pressure assembly: After the workpiece is clamped, the hydraulic cylinder 9 pushes the piston rod 68 downward to apply a set pressure to the workpiece and complete the assembly operation.

[0039] Automatic Reset: After pressure assembly, the hydraulic system is depressurized, and the oil in the rectangular drive chamber 66 flows back. Springs 69 on both sides of the piston 68 provide preload, pushing the piston 68 and clamping rod 67 to reset, releasing the workpiece. The springs 69 are symmetrically arranged to ensure smooth reset of the clamping rod 67 and prevent misalignment.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
