Description

A high-efficiency valve block clamping device Technical Field

[0001] This application relates to workpiece clamping technology in the field of machining, and in particular to a high-efficiency valve block clamping device. Background Technology

[0002] High-efficiency clamping devices are widely used in the machining field, especially in scenarios requiring frequent workpiece changes. With the rapid development of industrial production, higher demands are placed on the efficiency and precision of mechanical equipment. Traditional clamping methods often struggle to meet complex and ever-changing production needs, particularly in the machining of parts with various specifications. Quickly switching machining states becomes a key factor in improving production efficiency. Therefore, developing a high-efficiency valve block clamping device that can adapt to diverse machining needs and improve work efficiency is particularly important. Currently, the industry typically employs the following methods to address similar problems: first, manually adjusting the position of a single clamping tool to adapt to the machining requirements of different workpieces; second, designing a fixed multi-station clamping platform and using manual or simple robotic arms for station switching; and third, adopting a modular design concept, making the clamping components detachable for easy replacement. While these methods can alleviate the limitations of traditional single-station clamping to some extent, they still present many inconveniences in actual operation. Furthermore, the aforementioned conventional methods generally suffer from insufficient flexibility, failing to simultaneously achieve high efficiency, convenience, and machining continuity. For example, manual adjustment of a single clamping tool is time-consuming and labor-intensive, while fixed multi-station platforms limit their application scenarios due to a lack of flexibility. They cannot be processed while changing workpieces; processing can only continue after the change is complete. Furthermore, while existing modular designs can achieve some functional improvements, they still cannot fully meet the needs of rapid workpiece changeover in continuous processing, thus restricting overall production efficiency. Summary of the Invention

[0003] The purpose of this application is to overcome the above-mentioned technical problems and provide an efficient valve block clamping device.

[0004] A high-efficiency valve block clamping device includes a base, a base frame, and clamping devices mounted on the base frame. The base frame is rotatably connected to the base. The position of the clamping devices is adjusted by the relative rotation of the base frame and the base. Multiple clamping devices are provided, and each clamping device is detachably connected to the base frame. Continuous processing is achieved by rotating the base frame to change the workpiece processing state on the clamping devices, and the workpiece can be replaced after processing by disassembling the clamping devices. By adopting the above technical solution, multiple clamping devices are detachably connected to the base frame, allowing for rapid switching and replacement of workpieces under different processing states. Specific effects are as follows: The design of multiple clamping devices allows for the simultaneous loading of multiple workpieces, improving processing efficiency. The detachable connection between the clamping devices and the base frame facilitates the rapid replacement of completed workpieces, reducing non-processing time. The rotatable connection between the base frame and the base frame allows for flexible adjustment of the clamping device position, quickly moving the workpiece to be processed to the processing position and simultaneously moving the processed workpiece to the disassembly position, improving the continuity and ease of operation of the equipment. Preferably, the base is equipped with a locking device. By unlocking the locking device, the base frame can be rotated to change the processing position, and then locked again after the change is complete. This technical solution achieves stable locking and quick unlocking between the base frame and the base, facilitating the rotation of the base frame to change different processing positions. This design ensures accuracy and reliability when switching processing states, while improving operational efficiency and reducing processing errors caused by positional offset. Preferably, the base frame has a positioning plate at its bottom, and the base has a positioning disc. The base frame is installed through the cooperation of the positioning plate and the positioning disc. This technical solution achieves precise installation and stable connection between the base frame and the base. The cooperation between the positioning plate and the positioning disc ensures the correct assembly position of the base frame on the base, speeding up the adjustment time when placing the clamping device. Preferably, the surface of the positioning plate has a limiting protrusion, the end of which is a conical cylindrical surface. This technical solution effectively prevents the base frame from shifting during rotation, ensuring precise alignment between the base frame and the positioning disc. The protruding post is designed with a conical cylindrical surface, which makes the positioning process smoother, reduces assembly difficulty, and improves positioning accuracy and stability. Preferably, the positioning plate has an inner conical surface. By adopting the above technical solution, the inner conical surface on the positioning plate can closely cooperate with the conical cylindrical surface of the limiting protruding post, thereby improving the installation accuracy and stability between the base frame and the base. Through the guidance of the cone of the protruding post on the positioning plate and the inner conical surface on the positioning plate, the installation of the valve block clamping device can be completed quickly. This design effectively reduces the relative offset between the two, ensuring the reliability and accuracy of the clamping device during operation. At the same time, this structure simplifies the assembly process and improves operating efficiency. Preferably, the positioning plate is slidably connected to the base, and a spring is provided at the bottom of the positioning plate.By adopting the above technical solution, the positioning plate is slidably connected to the base and a spring is provided at the bottom of the positioning plate. Under the action of the spring, the positioning plate protrudes from the top horizontal surface of the base before installation, which facilitates the cooperation with the limiting protrusion on the positioning plate, further improving the assembly convenience and operational reliability.

[0005] In summary, this application includes at least one of the following beneficial technical effects: 1. By using the rotating connection between the base frame and the base and the design of multiple clamping devices, rapid switching of workpiece processing states is achieved, significantly improving production efficiency and adapting to diverse processing needs; 2. The clamping device is detachably connected to the base frame, facilitating timely replacement of processed workpieces during continuous processing and improving operational convenience; 3.

[0011] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of this utility model and not all possible implementations. Those skilled in the art can obtain other embodiments in combination with the embodiments of this utility model without creative effort, and these embodiments are also within the protection scope of this utility model. The inventors of this application have found that the high-efficiency valve block clamping device has the problem of insufficient flexibility and continuity in practical applications, and cannot simultaneously achieve high efficiency and convenience. To this end, this application mainly adopts the following solution, which achieves the effect of flexibly switching processing states and improving production efficiency by rotatably connecting multiple clamping devices with the base frame. Embodiment 1 A high-efficiency valve block clamping device provided by this application, as shown in Figures 1 and 2, includes a base 1, a base frame 2 and a clamping device 3, wherein the base frame 2 is rotatably connected to the base 1, and the position of the clamping device 3 is adjusted by relative rotation. The clamping device 3 is provided in multiple sets and is detachably connected to the base frame 2. Rotating the base frame 2 can change the workpiece processing state to achieve continuous processing. The workpiece that has been processed can be replaced by disassembling the clamping device 3, thereby improving the changeover efficiency.

[0012] Specifically, the base 1 is a mounting seat for the valve block clamping device that is fixedly installed at the processing position of the processing equipment. The base 1 is used to install the base frame 2 to realize the positioning and rotation limit of the base frame 2. The base 1 is provided with a receiving platform 11, and a rotating plate 111 is provided on the receiving platform 11. A plane bearing 112 is installed between the rotating plate 111 and the receiving platform 11. The rotating plate 111 is rotatably connected to the receiving platform 11 through the plane bearing 112.

[0013] The base frame 2, as the core component, supports multiple clamping devices 3 and enables position switching. A positioning plate 21 is located at the bottom of the base frame 2, with limiting protrusions 211 that cooperate with the rotating plate 111 on the receiving platform 11 of the base 1, allowing relative rotation with the base. A clamping mounting base 22 is provided on the base frame. The base frame 2 can be a square metal frame or a circular ring structure for fixing each clamping device 3. As shown in Figure 2, the clamping device 3 is detachably connected to the mounting base 22 of the base frame 2. Specifically, after the clamping device 3 is inserted into the mounting base 22 via positioning pins, it is fixed to the mounting base 22 with bolts. Multiple sets, such as four sets, of clamping devices 3 can be provided depending on the processing type. Each set of clamping devices 3 consists of a clamping unit 31 and a support unit 32. The clamping unit 31 mainly includes a clamping block and a limiting block; the support unit is the worktable of the clamping device, used to place the parts to be processed. Additionally, anti-slip pads can be embedded inside the clamping unit to prevent damage to precision surfaces. The locking device 4 prevents the base frame 2 from rotating further after a specific processing position is selected, ensuring the stability of subsequent processes. Typically, this is achieved using bolt locking or snap-fit ​​engagement. For ease of operation, a positioning pin 41 is provided on the top end face of the base 1, and positioning holes 23 corresponding to the number of clamping devices 3 are opened on the bottom of the base frame 2. The positioning pin 41 is controlled by a cylinder 42, enabling vertical movement. By adjusting the extension and retraction of the cylinder 42, the positioning pin 41 moves, allowing it to engage and disengage with the positioning holes 23 on the base frame 2, thus locking and releasing the base frame 2. Furthermore, the positioning pin 41 can be configured as an elastic telescopic positioning pin, with a chamfered or rounded corner at the front end. It can retract under pressure when contacting the bottom surface of the base 2 and pop out when it reaches the corresponding positioning hole 23, pre-positioning the base frame 2. Then, the extension rod of the cylinder 42 pushes out the positioning pin 41 to lock it in place. This simplifies the process and enhances safety measures. As shown in Figure 3, the base 1 is also provided with a positioning plate 12. The positioning plate 12 is used to cooperate with the positioning plate 21 provided at the bottom of the base frame 2 for positioning. Since the valve block clamping device is installed by hoisting, the addition of the positioning plate 12 can achieve efficient positioning of the base frame 2 and shorten the installation time.

[0014] Specifically, a positioning plate 12 is provided between the receiving platform 11 and the positioning plate 21. The center of the positioning plate 12 has a recessed inner conical surface, which guides and limits the protrusion 211. The end face of the limiting protrusion 211 has a conical surface, further facilitating its engagement with the positioning plate. The positioning plate 12 is slidably connected to the base 1, and a spring 13 is provided at the bottom of the positioning plate 12. The spring 13 acts on the positioning plate 12. When the base frame 2 is not installed on the base 1, the positioning plate 12 is supported by the spring, and the top surface of the positioning plate 12 protrudes, facilitating its engagement with the limiting protrusion 211 on the positioning plate 21. After installation, the abutment part at the bottom of the positioning plate 12 is used for the rotating plate 111 on the receiving platform 11, realizing the installation of the base frame 2 and the base. The principle of this embodiment is as follows: When the user uses the base frame 2, it is installed by hoisting. When it is hoisted directly above the base 1, the base frame 2 is slowly lowered so that the limiting protrusion at the bottom of the base frame 2 is aligned with the positioning plate 12. If there is any horizontal error, it is corrected by the tight fit between the conical surface on the limiting protrusion 211 and the inner conical surface on the positioning plate 12. After the positioning plate 12 abuts against the limiting protrusion 211, the base frame 2 continues to descend. By compressing the spring 13 at the bottom of the positioning plate 12, the spring 13 provides buffering and shock absorption for the descending base frame 2 until the positioning plate 21 is in complete contact with the rotating plate 111 on the receiving platform 11, thus realizing the installation of the base frame 2. Then, a suitable clamping device 3 is installed on the mounting base 22 of the base frame 2. The base frame 2 is rotatably connected to the receiving platform 11 through the rotating plate 111, and the locking device 4 locks the rotated base frame 2. The base frame 2 is rotated to the machining position to process the part on the clamping device 3. At the same time, the clamping device 3 on the other end of the base frame 2 is replaced, so as to realize machining on one end and clamping on the other end, thereby improving machining efficiency and saving time.
