Abstract
Description
Technical Field
[0001] This utility model relates to the field of CNC lathe technology, and more specifically, it relates to a CNC lathe tool setting device bracket. Background Technology
[0002] In the machining process of CNC lathes, precise tool position adjustment is crucial to ensuring machining accuracy. However, in the existing technology, it is usually necessary to manually disassemble and install the tool setter. This process is not only cumbersome and time-consuming, but also inefficient, especially when changing tools or adjusting the tool setter multiple times. It may even lead to damage to the tool setter or unstable installation, affecting the machining quality. Traditional installation methods generally rely on screws or fixing devices, which require a lot of time to disassemble and install and are complicated to operate, failing to meet the needs of rapid switching.
[0003] Furthermore, when adjusting the tool position, the existing fixing methods often fail to provide precise positioning. During the adjustment process, the rotating adjustment mechanism may become loose or shift, making it difficult to guarantee the accuracy after adjustment. This not only affects the working position of the tool but also increases the difficulty of operation during the adjustment process. In order to ensure the stability of the position after adjustment, a mechanism that can quickly and accurately lock the adjustment position must be designed. Most existing technologies lack an effective positioning mechanism, resulting in the inability to achieve reliable fixing after adjustment, which affects the continuity and accuracy of machining. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the problems existing in the prior art, this utility model provides a CNC lathe tool setting device bracket, which solves the technical problem mentioned in the background art that the traditional installation method generally relies on screws or fixing devices, and disassembly and installation require a lot of time and are complicated to operate, thus failing to meet the needs of rapid switching.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a CNC lathe tool setting device bracket, comprising a connecting rod, a rotating rod rotatably connected to the top of the connecting rod, an installation rod mounted on the top of the rotating rod, and a tool setting device body mounted on the installation rod via a quick-release mechanism. The quick-release mechanism includes a quick-release sleeve, a plug rod, a screw sleeve, a gear, a screw, a locking block, a locking groove, a guide groove, a sliding sleeve, a rack, a limiting sleeve, a baffle, and an abutment sleeve. The quick-release sleeve is mounted on the top of the installation rod, and the plug rod is fixed to the outer wall of the tool setting device body and inserted into the quick-release sleeve. Inside, multiple sets of threaded sleeves are rotatably mounted on the outer wall of the quick-release sleeve. Gears are mounted on the top of multiple sets of threaded sleeves. A screw is connected inside multiple sets of threaded sleeves. A locking block is mounted on the bottom of multiple sets of screws. Multiple sets of locking grooves are distributed on the outer wall of the insertion rod. A guide groove is located on the top of multiple sets of locking grooves. A sliding sleeve slides on the outer wall of the quick-release sleeve. Multiple sets of racks are mounted on the sliding sleeve and mesh with multiple sets of gears. A limiting sleeve slides on the outer wall of the quick-release sleeve. Multiple sets of baffles are mounted on the bottom surface of the limiting sleeve. An abutment sleeve is threadedly connected to the outer wall of the quick-release sleeve. The top of the mounting rod has an insertion hole that is compatible with the insertion rod.
[0008] The present invention is further configured such that a positioning mechanism is provided at the top of the connecting rod, the positioning mechanism including a limiting sleeve, a fixing block, a positioning groove, a push spring and a locking sleeve, the limiting sleeve being fixed at the top of the connecting sleeve, the fixing block having multiple sets of sliding on the upper arm of the limiting sleeve, the positioning groove having multiple sets distributed on the outer wall of the rotating rod, the push spring being installed on the outer wall of the limiting sleeve, and the locking sleeve being installed at the top of the push spring.
[0009] This invention is further configured such that the outer wall of the insertion rod is provided with a limiting strip, and multiple sets of the limiting strip are slidably connected to the inner wall of the quick-release sleeve. The slidable connection between the limiting strip and the inner wall of the quick-release sleeve ensures that the insertion rod can move within a specified range within the quick-release sleeve, preventing the insertion rod from being excessively inserted or pulled out. This allows the tool setter body to be accurately and stably connected to the mounting rod, reducing loosening or instability of the device during operation and ensuring the safe installation of the tool setter.
[0010] This invention is further configured such that all sets of the locking blocks and slots are polygonal and interlock. The polygonal design of the locking blocks and slots, through precise interlocking, ensures that the locking blocks are firmly embedded in the slots, preventing loosening or displacement and ensuring the stability of the tool setter body after installation. This interlocking method provides higher fixation reliability, increases the device's vibration resistance, and effectively avoids loosening problems caused by vibration during operation.
[0011] This invention is further configured such that multiple sets of screws are threadedly connected to multiple sets of threaded sleeves. The threaded connection between the screws and sleeves provides a reliable transmission method, allowing the screws to rotate smoothly and precisely, thereby driving the locking block to accurately engage with the locking slot, ensuring the stable fixation of the tool setter body. This design guarantees high efficiency and precision during device operation, reduces operational difficulties caused by friction or jamming, and improves work efficiency.
[0012] This invention is further configured such that each of the multiple sets of fixing blocks is connected to a return spring at its top end, and the other end of each of the multiple sets of return springs is connected to the outer wall of the limiting sleeve. The return springs, through their elastic action, ensure that the fixing blocks can quickly reset to their initial position when unlocked, thus allowing for quick and convenient adjustment of the device. The return spring design not only improves the ease of operation of the device but also ensures the stability of the fixing blocks during operation, reducing positioning errors caused by improper operation or fatigue.
[0013] This invention is further configured such that the bottom ends of the multiple sets of fixing blocks and the positioning grooves are all arc-shaped. The arc-shaped design reduces friction between the fixing blocks and the positioning grooves, avoiding difficulties in adjustment or disassembly due to jamming, and ensuring smooth operation of the device. The arc shape provides better positioning accuracy and makes the fit between the fixing blocks and the positioning grooves smoother, improving the overall performance of the device.
[0014] This invention is further configured such that the outer wall of the limiting sleeve is provided with guide plates, and multiple sets of guide plates are provided, all of which are slidably connected to the locking sleeve. The slidable connection between the guide plates and the locking sleeve allows the locking sleeve to move smoothly along the outer wall of the limiting sleeve, ensuring that the operation of the locking sleeve is not obstructed. Through the design of the guide plates, the locking sleeve can be accurately guided during adjustment, thereby making the positioning and locking process of the device more stable and precise, and avoiding misoperation caused by unstable sliding.
[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides a CNC lathe tool setting device bracket, which has the following beneficial effects:
[0017] 1. The quick-installation mechanism enables rapid installation and disassembly of the tool setter body, which not only greatly improves installation efficiency, but also ensures the stability and accuracy of the installation process through the cooperation of the sliding sleeve and the rack, avoiding errors in the manual installation process. The cooperation of the quick-installation sleeve and the insertion rod allows the tool setter to be installed or disassembled quickly, and work adjustments or replacements can be completed in a short time, saving a lot of time. Especially in production environments where frequent adjustments or replacements of the tool setter are required, it can significantly improve production efficiency.
[0018] 2. When disassembling the tool setter, rotating the screw sleeve drives the movement of the gear and the sliding sleeve, quickly releasing the lock between the locking block and the slot. The operation is simple and quick. This quick disassembly method ensures the efficient operation of the device and reduces the inconvenience and errors of manual operation, making equipment maintenance more convenient and efficient.
[0019] 3. The positioning mechanism ensures the stability of the rotating rod through precise structural design. This positioning mechanism not only ensures the accurate positioning of the rotating rod after adjustment, but also allows for easy release of the position lock when needed, facilitating quick adjustment of the angle or height of the rotating rod to meet the adjustment requirements of different cutting tools. Through these designs, the operation of the CNC lathe becomes more flexible and efficient, improving working accuracy and ensuring the high stability and durability of the equipment.

[0029] Please see Figures 1-5 A CNC lathe tool setting device bracket includes a connecting rod 1, a rotating rod 2 rotatably connected to the top of the connecting rod 1, and a mounting rod 3 mounted on the top of the rotating rod 2. A tool setting device body 4 is mounted on the mounting rod 3 via a quick-release mechanism. The quick-release mechanism includes a quick-release sleeve 5, an insert rod 6, a screw sleeve 7, a gear 8, a screw 9, a locking block 10, a locking groove 11, a guide groove 12, a sliding sleeve 13, a rack 14, a limiting sleeve 15, a baffle 16, and an abutment sleeve 17. The quick-release sleeve 5 is mounted on the top of the mounting rod 3. The insert rod 6 is fixed to the outer wall of the tool setting device body 4 and inserted into the quick-release sleeve 5. The screw sleeve 7 has multiple sets of rotatably mounted on the quick-release sleeve. The outer wall of the quick-release sleeve 5 has gears 8 installed at the top of multiple sets of threaded sleeves 7, screws 9 connected inside multiple sets of threaded sleeves 7, and locking blocks 10 installed at the bottom of multiple sets of screws 9. Multiple sets of locking grooves 11 are provided on the outer wall of the insertion rod 6, and guide grooves 12 are provided at the top of multiple sets of locking grooves 11. Sliding sleeves 13 slide on the outer wall of the quick-release sleeve 5, and multiple sets of racks 14 are installed on the sliding sleeves 13 and mesh with multiple sets of gears 8. Restricting sleeves 15 slide on the outer wall of the quick-release sleeve 5, and multiple sets of baffles 16 are provided on the bottom surface of the restricting sleeves 15. Abutting sleeves 17 are threadedly connected to the outer wall of the quick-release sleeve 5. The top of the mounting rod 3 has an insertion hole 18 that is compatible with the insertion rod 6.
[0030] The outer wall of the insertion rod 6 is provided with a limiting strip 24. Multiple sets of limiting strips 24 are provided and are slidably connected to the inner wall of the quick-release sleeve 5. The sliding connection between the limiting strip 24 and the inner wall of the quick-release sleeve 5 ensures that the insertion rod 6 can be accurately positioned within the quick-release sleeve 5 and limits its range of movement, preventing the insertion rod 6 from being over-inserted or pulled out, thereby ensuring the stability and accuracy of the tool setter.
[0031] Multiple sets of locking blocks 10 and locking slots 11 are all polygonal and interlock. The cooperation between the polygonal locking blocks 10 and the locking slots 11 allows the locking blocks 10 to be firmly embedded in the locking slots 11, preventing loosening or displacement, thereby ensuring that the tool setter body 4 remains stable after installation, providing a highly reliable fixing effect and increasing vibration resistance.
[0032] Multiple sets of screws 9 are threadedly connected to multiple sets of threaded sleeves 7. The threaded connection between the screws 9 and the threaded sleeves 7 provides a precise transmission method, which can effectively drive the locking or unlocking of the locking block 10 and the locking groove 11, ensuring the rapid and accurate adjustment of the device, while reducing friction and wear, and ensuring smooth operation.
[0033] In this embodiment, firstly, the insertion rod 6 is fixed to the outer wall of the tool setting device body 4 and inserted into the quick-release sleeve 5 on the mounting rod 3. Through multiple sets of guide grooves 12, it slides and connects with the locking block 10. Through the cooperation of the insertion rod 6 and the quick-release sleeve 5, the insertion rod 6 can accurately align within the quick-release sleeve 5, ensuring a tight connection between the tool setting device body 4 and the quick-release sleeve 5. Next, the threaded sleeve 7 is rotatably mounted on the outer wall of the quick-release sleeve 5. Through the sliding sleeve 13, it drives the rack 14 to mesh with the gear 8, and the rotating gear 8 drives the threaded sleeve 7 to rotate, thereby causing the screw 9 to rotate. The rotation of screw 9 allows the locking block 10 to slide and engage with the corresponding position in the slot 11. The locking block 10, positioned by the slot 11 and the insertion rod 6, ensures the tool setter body 4 is firmly fixed. The sliding sleeve 13 is slid to the bottom of the quick-release sleeve 5. At this point, the teeth on the multiple sets of gears 8 are aligned with the multiple sets of baffles 16. The rotating abutment sleeve 17 engages with the outer wall of the quick-release sleeve 5 through a threaded connection, pushing the limiting sleeve 15 to slide. The limiting sleeve 15 pushes the multiple sets of baffles 16 to engage with the teeth on the outer wall of the multiple sets of gears 8, limiting the movement of the gears 8. During the entire operation of the device, the connecting rod 1 provides support and transmission, connecting the entire tool setter bracket to the CNC lathe. During operation, the height and angle of the tool setter can be adjusted by rotating the rotating rod 2 at the top of the connecting rod 1 to adapt to different tool measurement needs.
[0034] Please see Figure 5 As one implementation of the positioning mechanism: a positioning mechanism is provided at the top of the connecting rod 1. The positioning mechanism includes a limiting sleeve 19, a fixing block 20, a positioning groove 21, a push spring 22, and a locking sleeve 23. The limiting sleeve 19 is fixed to the top of the connecting sleeve. The fixing block 20 is provided with multiple sets of sliding on the upper arm of the limiting sleeve 19. The positioning groove 21 is provided with multiple sets distributed on the outer wall of the rotating rod 2. The push spring 22 is installed on the outer wall of the limiting sleeve 19, and the locking sleeve 23 is installed at the top of the push spring 22.
[0035] Each of the multiple sets of fixing blocks 20 has a return spring 25 connected to its top end, and the other end of each return spring 25 is connected to the outer wall of the limiting sleeve 19. The elasticity of the return spring 25 ensures that the fixing block 20 can quickly return to its initial position after being unlocked, allowing the device to be quickly adjusted and restored to its standard state, simplifying the operation process and maintaining the stability and flexibility of the device.
[0036] The bottom ends of multiple sets of fixing blocks 20 and positioning grooves 21 are all designed in an arc shape. The arc shape design reduces the friction between the fixing blocks 20 and the positioning grooves 21, avoids jamming problems, makes the cooperation between the fixing blocks 20 and the positioning grooves 21 smoother, ensures smoothness during precise positioning, and improves overall work efficiency.
[0037] The outer wall of the limiting sleeve 19 is provided with guide plates 26, and multiple sets of guide plates 26 are provided, all of which are slidably connected to the locking sleeve 23. The guide plates 26 can smoothly guide the locking sleeve 23 to slide, ensuring that the operation of the locking sleeve 23 is not obstructed, and can provide precise positioning to avoid deviations caused by improper operation, thus ensuring the stability and efficiency of the locking process.
[0038] More specifically, when the rotating rod 2 needs to be positioned, multiple sets of push springs 22 push the locking sleeve 23 to slide along the limiting sleeve 19 and abut against the top of multiple sets of fixing blocks 20, so that the bottom of the multiple sets of fixing blocks 20 is engaged in the positioning groove 21 and simultaneously squeezes the multiple sets of return springs 25. When the positioning needs to be released, the locking sleeve 23 is pushed to slide down along the limiting sleeve 19 and squeezes the multiple sets of push springs 22 and releases the abutment against the multiple sets of fixing blocks 20. The elastic reset of the multiple sets of return springs 25 pulls the multiple sets of fixing blocks 20 to move outward and disengage from the positioning groove 21, releasing the restriction on the rotating rod 2. Then the positioning rod can be rotated for adjustment.
[0039] In summary, during the use or operation of the entire device: First, the insertion rod 6 is fixed to the outer wall of the tool setter body 4 and inserted into the quick-release sleeve 5 on the mounting rod 3. Through multiple sets of guide grooves 12 and sliding connections with the locking block 10, the insertion rod 6 and the quick-release sleeve 5 work together to accurately align the insertion rod 6 within the quick-release sleeve 5, ensuring a tight connection between the tool setter body 4 and the quick-release sleeve 5. Next, the threaded sleeve 7 is rotatably mounted on the outer wall of the quick-release sleeve 5. Through the sliding sleeve 13, it drives the rack 14 to mesh with the gear 8, and the rotating gear 8 drives the threaded sleeve 7 to rotate, thereby causing the screw 9 to rotate. The rotation of screw 9 allows the locking block 10 to slide and engage with the corresponding position in the slot 11. The locking block 10, positioned by the slot 11 and the insertion rod 6, ensures the tool setter body 4 is firmly fixed. The sliding sleeve 13 is slid to the bottom of the quick-release sleeve 5. At this point, the teeth on the multiple sets of gears 8 are aligned with the multiple sets of baffles 16. The rotating abutment sleeve 17 engages with the outer wall of the quick-release sleeve 5 through a threaded connection, pushing the limiting sleeve 15 to slide. The limiting sleeve 15 pushes the multiple sets of baffles 16 to engage with the teeth on the outer wall of the multiple sets of gears 8, limiting the movement of the gears 8. During the entire operation of the device, the connecting rod 1 provides support and transmission, connecting the entire tool setter bracket to the CNC lathe. During operation, the height and angle of the tool setter can be adjusted by rotating the rotating rod 2 at the top of the connecting rod 1 to adapt to different tool measurement needs.
[0040] When the rotating rod 2 needs to be positioned, multiple sets of push springs 22 push the locking sleeve 23 to slide along the limiting sleeve 19 and abut against the top of multiple sets of fixing blocks 20, so that the bottom of the multiple sets of fixing blocks 20 is engaged in the positioning groove 21 and simultaneously squeezes the multiple sets of return springs 25. When the positioning needs to be released, push the locking sleeve 23 to slide down along the limiting sleeve 19 and squeeze the multiple sets of push springs 22 and release the abutment of the multiple sets of fixing blocks 20. The elastic return of the multiple sets of return springs 25 pulls the multiple sets of fixing blocks 20 to move outward and disengage from the positioning groove 21, releasing the restriction on the rotating rod 2. Then the positioning rod can be rotated for adjustment.
[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. 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 variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
