Description

Technical Field

[0001] This utility model relates to the field of casting turning technology, and more specifically, it relates to a vibration-damping clamping device for casting turning. Background Technology

[0002] In the process of turning castings, it is necessary to quickly change and adjust the clamping components according to the shape and size of the castings to adapt to different processing requirements. The clamping components of existing clamping devices are mostly installed by bolt fastening or pin insertion. Both installation and disassembly require special tools and involve many steps. Frequent changes seriously affect processing efficiency. At the same time, there is no quick snap-locking function between the clamping components and the mounting base. Multiple fasteners need to be tightened one by one to complete the fixation. The entire installation process is time-consuming and labor-intensive, making it difficult to meet the actual needs of rapid changeover in batch processing.

[0003] After the clamping device completes locking, it needs to maintain a stable and reliable connection to withstand the cutting force and vibration generated during turning. Existing locking mechanisms lack automatic limit function after locking, requiring operators to manually perform a secondary locking operation, increasing the operation steps and time. Furthermore, the locking components lack an automatic reset function, requiring manual repositioning for each operation. Disassembly also requires manually pulling out the connecting components, which is inconvenient. The overall operation process is complex and lacks automation. Under vibration conditions, the locking state is prone to loosening, affecting the clamping reliability. Utility Model Content

[0008] The present invention is further configured such that limit holes are provided on the outer walls of multiple sets of rotating rods, and multiple sets of limit holes are provided and respectively inserted into multiple sets of limit rods to achieve precise positioning and stable locking of the control sleeve position.

[0009] The present invention is further configured such that the outer wall of the fixed sleeve is provided with an installation groove, and the installation groove is provided in multiple sets and is rotatably connected to multiple sets of clamping plates respectively, providing a fulcrum for the multiple sets of clamping plates to facilitate the clamping plates to rotate and engage in the groove to complete the engagement.

[0010] The present invention is further configured such that a control groove is provided on the inner side of the control sleeve, and the control groove abuts against multiple sets of abutment plates. By moving the control sleeve, the abutment plates are pushed to rotate the locking plate, thereby realizing the quick locking and unlocking of the insertion rod.

[0011] The present invention is further configured such that a guide plate is fixedly provided on the inner side of the control sleeve, and a guide groove is provided on the outer wall of the fixed sleeve. Multiple sets of the guide plate and the guide groove are provided and slidably connected to ensure the stability and guidance of the control sleeve moving along the outer wall of the fixed sleeve.

[0012] The present invention is further configured such that a reset block is fixedly provided on the top surface of the rotating sleeve, and a pressure plate is fixedly provided on the outer wall of the fixed sleeve. Multiple sets of reset blocks and pressure plates are provided, and reset springs are respectively connected to their outer sides. Arc-shaped rods are fixedly provided on the outer walls of the multiple sets of reset blocks, and the multiple sets of arc-shaped rods are slidably connected to the multiple sets of pressure plates, so as to provide automatic reset elasticity for the rotating sleeve and ensure the stability and guidance of the rotation process.

[0013] The present invention is further configured such that a compression spring is connected inside the insertion rod, and a compression block is connected to the top of the compression spring. The compression block is slidably connected to the insertion rod, and after unlocking, the compression spring automatically pushes out the fixing sleeve for easy and quick disassembly.

[0014] The present invention is further configured such that a vortex groove is formed in the disc body, and multiple sets of movable blocks are threadedly connected to the vortex groove, so as to realize that multiple sets of movable blocks move synchronously in the radial direction to facilitate adjustment of the clamping position.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a vibration-damping clamping device for turning castings, which has the following advantages:

[0017] 1. This device achieves rapid positioning of the claw by having its bottom surface abut against the movable block and inserting the rod into the insertion hole on the outer wall of the claw. After the fixing sleeve is inserted into the top of the rod, the control sleeve is slid to make the control groove on its inner side push multiple sets of abutment plates, which in turn drive multiple sets of locking plates to rotate and engage in the locking groove on the outer wall of the rod. The sliding cooperation between the guide plate and the guide groove ensures the stability of the control sleeve movement. The entire installation process does not require tools and is simple and quick to operate, effectively improving the claw replacement efficiency and ease of operation.

[0018] 2. This device uses multiple sets of return springs to connect the return block and the pressure plate to provide automatic return force for the rotating sleeve. After the snap-fit ​​is completed, the return spring automatically pushes the return block to drive the rotating sleeve to rotate, so that the multiple sets of limit holes on the multiple sets of rotating rods on the outer wall of the rotating sleeve are aligned and inserted with the multiple sets of limit rods on the outer wall of the control sleeve. This achieves automatic limit locking of the control sleeve position without the need for manual secondary operation. The sliding cooperation between the arc rod and the pressure plate ensures the stability and guidance of the rotating sleeve during rotation, effectively simplifying the operation process and improving the reliability of the locking state. Under vibration conditions, it can effectively prevent the locking components from loosening.

[0019] 3. This device incorporates a compression spring and compression block within the insertion rod. When installing the fixing sleeve, the compression block is compressed, causing the compression spring to store energy. When the chuck needs to be disassembled, rotating the sleeve causes the limiting hole to disengage from the limiting rod, releasing the limiting of the control sleeve. After multiple sets of chucks disengage from the slots and release the clamping of the insertion rod, the compression spring automatically resets, pushing the compression block to eject the fixing sleeve from the top of the insertion rod. This allows for rapid separation of the fixing sleeve from the insertion rod without manual removal, facilitating quick disassembly and replacement of the chuck, effectively improving assembly and disassembly efficiency and reducing operational difficulty.
