Description

Technical Field

[0001] This utility model relates to the field of chuck shaft and bushing connection technology, and in particular to an adjustable hydraulic pressurized chuck shaft and bushing integrated assembly. Background Technology

[0002] In the field of machining, the connection stability between the chuck shaft and bushing is a core element in ensuring machining accuracy and safe equipment operation. Traditional chuck shaft and bushing assemblies often employ a single fixed structure, such as connection via bolts, a single set of pins, or a simple keyway fit. However, this single fixed method has gradually revealed many insurmountable defects in practical applications, failing to meet the demands of modern machining for high precision, high stability, and high reliability. Traditional single fixed structures perform poorly under complex loads. During hydraulic pressurization, the chuck generates significant axial thrust and radial torque, while cutting forces, vibrations, and centrifugal forces generated by high-speed equipment operation continuously act on the connection. A single fixed structure struggles to effectively distribute these loads, easily leading to stress concentration at the connection. Over time, this can result in bolt loosening, pin wear, or keyway deformation, ultimately causing the connection to loosen. The assembly process for traditional connection structures is often cumbersome. Many structures require multiple tools for tightening or calibration, demanding high operator skills and resulting in low assembly efficiency, especially in mass production or scenarios requiring frequent changes in workpiece specifications, severely impacting production progress. Furthermore, the locking mechanism of the traditional structure is imperfect. During equipment operation, the connecting parts are prone to unexpected loosening due to external forces such as vibration and impact. The existing structure lacks an effective limiting and anti-loosening device, making it difficult to stably lock the connection state and increasing the safety hazards of equipment operation. Therefore, we propose an adjustable hydraulic pressure chuck shaft and bushing integrated assembly to solve this problem. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable hydraulic pressure chuck shaft and bushing integrated assembly to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable hydraulic pressure chuck shaft and bushing integrated assembly includes: a tube shaft one and a tube shaft two. Connecting chuck one and connecting chuck two are respectively fixedly installed on the outer sides of the adjacent ends of tube shaft one and tube shaft two. Two sets of mounting positioning plates are fixedly installed on one side of connecting chuck two. Both sets of mounting positioning plates are movably inserted into the interior of connecting chuck one. Connecting chuck one has two sets of placement grooves and sliding grooves inside. Connecting chuck two has two sets of rectangular grooves inside. Connecting components and limiting components are respectively arranged inside the placement grooves, sliding grooves, and rectangular grooves located on the same side. The components include: a sliding frame, in which a sliding plate is slidably mounted; a pull rod and a plug rod are fixedly mounted on both sides of the sliding plate, the plug rod being movably inserted into the interior of a connecting chuck; a connecting plate is fixedly mounted on the bottom of the sliding frame; a square plate is fixedly mounted on the bottom of the connecting plate; a plug block is fixedly mounted on the top of the square plate, the plug block being movably inserted into the interior of a mounting positioning plate; and a limiting component including: a movable plate, in which a limiting plate and a connecting shaft are fixedly mounted on both sides of the movable plate, the limiting plate being movably inserted into the interior of a placement groove, the top of the limiting plate being movably abutting against the bottom of the sliding frame.

[0005] Preferably, the two sets of sliding frames are slidably installed inside the corresponding placement slots, and each set of sliding frames is provided with a spring. The two ends of the two sets of springs are respectively fixedly connected to the inner wall of one side of the corresponding slide plate and sliding frame. One end of each set of pull rods slides through to one side of the corresponding sliding frame, and a pull plate is fixedly installed on one end of each set of pull rods.

[0006] Preferably, each of the two sets of placement slots is provided with a second spring, and the two ends of the two sets of second springs are respectively fixedly connected to the corresponding sliding frame and the inner wall of one side of the placement slot.

[0007] Preferably, the two sets of square plates are slidably installed inside the corresponding slide grooves, and each set of slide grooves is provided with a spring three. The two ends of the two sets of spring three located on the same side are fixedly connected to the inner wall of one side of the corresponding square plate and slide groove.

[0008] Preferably, the two sets of movable plates are slidably installed inside the corresponding rectangular grooves, and springs four are sleeved on the outer side of the two sets of connecting shafts. The two ends of the two sets of springs four are fixedly connected to the inner wall of one side of the corresponding movable plate and the rectangular groove, respectively. The two sets of connecting shafts slide through to one side of the connecting chuck two, and a pull plate two is fixedly installed at one end of the two sets of connecting shafts.

[0009] Preferably, guide rods are slidably installed inside both sets of square plates, and the two ends of the two sets of guide rods are fixedly connected to the inner walls of the corresponding sliding grooves on both sides. Limiting grooves are opened on both sides of the inner walls of the rectangular grooves, and limiting blocks are fixedly installed on both sides of the movable plate. The two sets of limiting blocks are slidably installed inside the corresponding limiting grooves.

[0010] In this utility model, the adjustable hydraulic pressure chuck shaft and bushing integrated assembly is provided with a connecting component. By pulling the pull plate one horizontally to the left, the pull plate one moves the pull rod and the sliding plate, causing the sliding plate to disengage the insert rod from the inside of the connecting chuck one while simultaneously compressing spring one. Then, by pulling the pull plate one vertically, the sliding frame moves the connecting plate while simultaneously compressing spring two, causing the connecting plate to move the square plate, which in turn moves the insert block while simultaneously compressing spring three. This causes the insert block to move into the sliding groove. Through the reset of springs one, two, and three, the insert rod is re-inserted into the inside of the connecting chuck one, and the insert block is movably inserted into the inside of the mounting positioning plate. This facilitates the connection of the chuck... The first and second connecting chucks are effectively double-fixed. The insertion and engagement of the plug rod with the first connecting chuck and the insertion and engagement of the plug block with the mounting positioning plate form a double limiting structure, which facilitates the stable fixing of the first and second connecting chucks. This double fixing method greatly improves the overall rigidity of the connection part, so that the assembly can maintain a stable connection state when subjected to complex loads such as the impact force generated by hydraulic pressurization and the cutting force during workpiece processing. It effectively reduces the risk of decreased processing accuracy and equipment wear caused by loose connection, significantly improves the structural load-bearing capacity and working reliability of the assembly, and provides a stable structural foundation for subsequent hydraulic pressurization control and workpiece processing accuracy. In this invention, an adjustable hydraulic pressure chuck shaft and bushing integrated assembly is provided. By setting a limiting component, pulling the second pull plate causes the connecting shaft to move the moving plate while simultaneously squeezing the fourth spring. This causes the moving plate to move the limiting plate into the rectangular groove. Under the elastic force of the fourth spring, the moving plate drives the limiting plate to insert into the placement groove and movably abut against the bottom of the sliding frame, thus limiting the sliding frame and preventing the insertion rod and block from disengaging from their corresponding insertion positions. This ensures the double-fixed structure remains stable at all times. This multi-locking mechanism superimposes and enhances the connection strength between connecting chuck one and connecting chuck two, effectively resisting external impacts even under complex working conditions. This significantly reduces the risk of connection loosening or failure, and significantly improves the overall reliability of the assembly connection. Attached Figure Description

This facilitates effective double fixation of the connecting chuck 3 and the connecting chuck 4. When the pull plate 606 is released, the moving plate 602, under the elastic force of the spring 605, drives the limiting plate 601 to insert into the placement slot and move against the bottom of the slide frame 501, thus limiting the slide frame 501 and preventing it from shifting due to external force during operation. This achieves multiple locking and fixing of the connecting chuck 3 and the connecting chuck 4. When separation is required, the operation can be repeated to release the connection lock of the connecting chuck 3 and the connecting chuck 4.
