Description

Technical Field

[0001] This utility model relates to the field of CNC lathe tool technology, specifically a CNC machine tool tool holder with quick tool change capability. Background Technology

[0002] CNC lathes are high-precision, high-efficiency automated machine tools with a wide range of machining capabilities. They can process straight cylinders, inclined cylinders, arcs, and various threads, and perform various compensation functions for arc interpolation. They have played a significant role in the mass production of complex parts, and the CNC machine tool tool holder plays a very important role.

[0003] CN219234549U discloses a CNC machine tool clamping mechanism. This device inserts the upper part of the tool between four locking plates, facilitating the tightening of nuts. This causes two annular plates to move closer together along positioning screws, which in turn causes two hinged rods to move the locking plate laterally, locking it against the surface of the locking plate. The locking plate then slides along a groove and locks against the tool. When the nut is tightened, the conical head abuts against the positioning hole, ensuring the horizontal stability of the annular plate. This makes the annular plate more stable under the locking of the nut, ensuring the overall fastening strength after installation. This facilitates tool positioning and clamping, and allows for the installation of tools of different specifications. However, this patent still has the following problems in practical use:

[0004] This device inserts the upper part of the cutter between four locking plates, causing two annular plates to move closer together along the positioning screws. This, in turn, causes two hinged rods to move the locking plates laterally, making the annular plates more stable under the locking of the nuts. This facilitates the positioning and setting of the cutter. However, the device requires the use of tools such as wrenches to operate the nuts during the cutter installation process, which greatly reduces the efficiency of cutter installation and cannot achieve the effect of quick installation and removal of cutters, causing inconvenience to the staff during use.

[0005] A CNC machine tool tool holder with quick tool change capability is proposed to address the problems mentioned above. Utility Model Content

Currently, the tool is inserted between four locking plates, and two annular plates are brought closer together along the positioning screws. This causes two hinge rods to move the locking plates laterally, making the annular plates more stable under the locking of the nuts, thus facilitating tool positioning. However, this device requires the use of wrenches or other tools to operate the nuts during tool installation, which greatly reduces tool installation efficiency and fails to achieve the effect of quick tool installation and removal, causing inconvenience to operators.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a CNC machine tool tool holder with quick tool change capability, comprising a tool holder, wherein a tool head body is provided at the bottom end of the tool holder; an adjustment mechanism is provided at the bottom end of the tool holder, and a limit component is provided inside the adjustment mechanism;

[0008] The adjustment mechanism includes a circular box mounted on the bottom of the tool holder. A gear is rotatably connected to the bottom of the circular box, and a gear is rotatably connected to one side of the circular box, meshing with the gear. A rotating rod is rotatably connected to one side of the circular box, and a first conical tooth is installed on one side of the gear. A second conical tooth is installed at one end of the rotating rod inside the circular box, meshing with the first and second conical teeth. An arc-shaped rod is rotatably connected to the side of the gear away from the center, and a fixed rod is installed inside one end of the arc-shaped rod. A sliding groove is formed inside one side of the circular box, and one end of the fixed rod is slidably connected inside the sliding groove. An arc-shaped plate is installed on the outer side of one end of the fixed rod, and an insert block is installed on the inner side of the arc-shaped plate. A connecting block is provided at the bottom of the circular box, and the insert block and the connecting block are inserted into each other.

[0009] Preferably, a limiting groove is formed inside one side of the circular box, and a support rod is installed inside the limiting groove. A connecting plate is rotatably connected to the outer side of one end of the fixed rod, and sliders are symmetrically installed at both ends of the connecting plate. One end of the slider is slidably connected to the outer side of the support rod, and a first retraction spring is sleeved on the outer side of the support rod.

[0010] Preferably, the limiting component includes a fixed box installed on one side of the round box, and fixed tubes are symmetrically installed inside both ends of the fixed box. A slide rod is slidably connected inside the fixed tube, and a slide plate is installed at one end of the slide rod. A slot is opened on the outer side of one end of the rotating rod, and an insert plate is installed on one side of the slide plate. The insert plate is inserted into the slot, and a second retraction spring is sleeved on the outer side of the slide rod.

[0011] Preferably, sliding sleeves are symmetrically installed on both sides of the fixed tube, and a movable rod is slidably connected inside the sliding sleeve, with one end of the movable rod being fixedly connected to the sliding plate.

[0013] Preferably, one end of the rotating rod passes through the fixed box and is rotatably connected to the fixed box.

[0014] Preferably, the top end of the cutter head body is fixedly connected to the connecting block.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: A CNC machine tool tool holder with quick tool change capability is described below: The operator rotates a rotating rod to drive the rotation of the second conical tooth, which in turn drives the rotation of the gear. The gear's rotation drives the rotation of the gear disc, which in turn drives multiple sets of arc-shaped rods to rotate. The rotation of the arc-shaped rods causes the fixed rod to slide inside the groove. At this time, the fixed rod drives the arc-shaped plate to move, thereby using multiple sets of arc-shaped plates to press and limit the outer side of the top of the connecting block. At this time, multiple sets of insert blocks are inserted into the connecting block, thus achieving the effect of quickly fixing and limiting the connecting block, thereby enabling… This design enables quick installation and disassembly of the cutter head body, facilitating inspection and maintenance by staff. Compared to existing technologies using bolts and nuts for fixing, this method is more convenient and significantly improves the efficiency of daily maintenance. By pulling the sliding rod inside the fixed tube, the rod causes the sliding plate to slide inside the fixed box. At this point, the second compression spring contracts, and its reset function allows multiple insert plates to connect to the slots. This, in turn, fixes and limits the adjusted rotating rod, preventing external forces from causing it to rotate and reducing the probability of the curved plate shifting.

[0016] 1. The operator attaches the top of the connecting block to the tool holder, then rotates the rotating rod to drive the second conical tooth to rotate. The rotation of the second conical tooth drives the rotation of the first conical tooth, which in turn drives the rotation of the gear. The gear drives the rotation of the gear disc, which in turn drives multiple sets of arc rods to rotate. The rotation of the arc rods causes the fixing rod to slide inside the groove. At this time, the fixing rod drives the arc plate to move. The multiple sets of arc plates move in a convergence and unfolding trajectory, thereby using the multiple sets of arc plates to squeeze and limit the outer side of the top of the connecting block. At this time, multiple sets of insert blocks are inserted into the connecting block, thereby achieving the effect of quickly fixing and limiting the connecting block. This enables the quick installation and disassembly of the tool head body, making it easier for operators to inspect and maintain the tool head body. Compared with the bolt and nut fixing method in the existing technology, this is more convenient and greatly improves the daily maintenance efficiency of the tool head body. Furthermore, operators can install tool heads of various specifications at the bottom of the connecting block, thus achieving the effect of installing and disassembling tool heads of various specifications, bringing practicality to operators during use.

[0017] 2. When the operator pulls the sliding rod, it slides inside the fixed tube. At this time, the sliding rod drives the slide plate to slide inside the fixed box. The second contraction spring contracts, and by releasing the sliding rod, the second contraction spring returns to its original position, allowing multiple sets of insert plates to be inserted into the slots. This fixes and limits the adjusted rotating rod, preventing external forces from causing the rotating rod to rotate on its own, reducing the probability of the curved plate shifting, making the connection block installation more stable, and providing convenience for operators.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 The present invention provides a technical solution: a CNC machine tool tool holder with quick tool change, including a tool holder 1, a tool body 101 at the bottom end of the tool holder 1; an adjustment mechanism 2 at the bottom end of the tool holder 1, and a limit component 3 inside the adjustment mechanism 2;

[0027] The adjusting mechanism 2 includes a circular box 201 mounted on the bottom of the tool holder 1. A gear disk 202 is rotatably connected to the bottom inside the circular box 201, and a gear 203 is rotatably connected to one side inside the circular box 201. The gear 203 meshes with the gear disk 202. A rotating rod 204 is rotatably connected to one side inside the circular box 201, and a first conical tooth 205 is mounted on one side of the gear 203. A second conical tooth 205 is mounted on one end of the rotating rod 204 inside the circular box 201. Two conical teeth 206 are connected, with the first conical tooth 205 meshing with the second conical tooth 206. An arc-shaped rod 207 is rotatably connected to the side of the gear disc 202 furthest from the center. A fixing rod 208 is installed inside one end of the arc-shaped rod 207. A sliding groove 209 is formed inside one side of the circular box 201, and one end of the fixing rod 208 is slidably connected inside the sliding groove 209. An arc-shaped plate 210 is installed on the outer side of one end of the fixing rod 208. The inner side of the 10 is equipped with a plug 211, and the bottom of the round box 201 is provided with a connecting block 212. The top of the cutter body 101 is fixedly connected to the connecting block 212, and the plug 211 and the connecting block 212 are inserted together. Thus, multiple sets of arc plates 210 are used to squeeze and limit the outer side of the top of the connecting block 212. At this time, multiple sets of plug 211 and the connecting block 212 are inserted together, so as to achieve the effect of quickly fixing and limiting the connecting block 212, and thus achieve the effect of quickly installing and disassembling the cutter body 101. This makes it easier for staff to inspect and maintain the cutter body 101. Compared with the bolt and nut fixing method in the prior art, it is more convenient and greatly improves the daily maintenance efficiency of the cutter body 101. Moreover, staff can install cutter bodies 101 of various specifications at the bottom of the connecting block 212, so as to achieve the effect of installing and disassembling cutter bodies 101 of various specifications, which brings practicality to the staff when using it.

[0028] Each side of the round box 201 has a limiting groove 213, and a support rod 214 is installed inside the limiting groove 213. A connecting plate 215 is rotatably connected to one end of the fixed rod 208. Slider 216s are symmetrically installed at both ends of the connecting plate 215, and one end of the slider 216 is slidably connected to the outside of the support rod 214. A first retraction spring 217 is sleeved on the outside of the support rod 214. The movement of the arc rod 207 drives the movement of the connecting plate 215, and the movement of the connecting plate 215 causes the slider 216 to slide on the support rod 214. The first contraction spring 217 extends, and its contraction and restoring properties assist the arc plate 210 in moving, thereby making the movement of the arc plate 210 more stable. A handle 218 is installed at one end of the rotating rod 204, and a limit block 219 is installed on one side of the inside of the round box 201. The rotating rod 204 is located inside the limit block 219 and is engaged and rotated. The design of the handle 218 makes it easier for the operator to operate the rotating rod 204, and the design of the limit block 219 makes the rotation of the rotating rod 204 more stable.

[0029] The limiting component 3 includes a fixed box 301 installed on one side of the round box 201. One end of the rotating rod 204 passes through the fixed box 301 and is rotatably connected to it. Fixed tubes 302 are symmetrically installed inside both ends of the fixed box 301. A sliding rod 303 is slidably connected inside the fixed tubes 302. A sliding plate 304 is installed at one end of the sliding rod 303. Slots 305 are provided on the outer side of one end of the rotating rod 204. Insert plates 306 are installed on one side of each sliding plate 304, and the insert plates 306 are inserted into the slots 305. A second retraction spring 307 is sleeved on the outer side of the sliding rod 303. The second retraction spring 307, through its restoring property, allows the sliding rod to stop. The multiple sets of insert plates 306 can be inserted into the slots 305, thereby fixing and limiting the adjusted rotating rod 204. This prevents the rotating rod 204 from rotating due to external forces, reduces the probability of the arc plate 210 shifting, and makes the connecting block 212 more stable to install, providing convenience for the operator. Sliding sleeves 308 are symmetrically installed on both sides of the fixing tube 302, and a moving rod 309 is slidably connected inside the sliding sleeve 308. One end of the moving rod 309 is fixedly connected to the slide plate 304. By sliding the moving rod 309 inside the fixing tube 302, the movement of the slide plate 304 can be made more stable.

[0030] Working principle: Before using this type of CNC machine tool tool holder with quick-change tooling, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6As shown, the operator attaches the top of the connecting block 212 to the tool holder 1, and then rotates the rotating rod 204 to drive the second conical tooth 206 to rotate. The rotation of the second conical tooth 206 drives the first conical tooth 205 to rotate, which in turn drives the gear 203 to rotate. The gear 203 then drives the gear disc 202 to rotate, which in turn drives multiple sets of arc-shaped rods 207 to rotate. The rotation of the arc-shaped rods 207 causes the fixing rod 208 to slide inside the slide groove 209. At this time, the fixing rod 208 drives the arc plate 210 to move. The multiple sets of arc-shaped plates 210 move in a convergence and unfolding trajectory, thereby using the multiple sets of arc-shaped plates 210 to squeeze and limit the outer side of the top of the connecting block 212. At this time, multiple sets of insert blocks 211 are inserted into the connecting block 212, thereby achieving the effect of quickly fixing and limiting the connecting block 212, and thus achieving the effect of quickly installing and disassembling the tool head body 101, which facilitates... The inspection and maintenance of the cutter head body 101 by the staff is more convenient than the bolt and nut fixing method in the existing technology, which greatly improves the daily maintenance efficiency of the cutter head body 101. Moreover, the staff can install cutter head bodies 101 of various specifications at the bottom of the connecting block 212, so as to realize the installation and disassembly of cutter head bodies 101 of various specifications, which brings practicality to the staff. The movement of the arc rod 207 drives the movement of the connecting plate 215. The movement of the connecting plate 215 drives the slider 216 to slide on the support rod 214. At this time, the first contraction spring 217 extends. The contraction and reset property of the first contraction spring 217 can assist the movement of the arc plate 210, thereby making the movement of the arc plate 210 more stable. The design of the handle 218 makes it easy for the staff to operate the rotating rod 204. The design of the limit block 219 makes the rotation of the rotating rod 204 more stable.

[0031] When the operator pulls the slide bar 303 to slide inside the fixed tube 302, the slide bar 303 drives the slide plate 304 to slide inside the fixed box 301. At this time, the second contraction spring 307 contracts. By releasing the slide bar 303 and then restoring the second contraction spring 307, multiple sets of insert plates 306 can be inserted into the slots 305. This can fix and limit the adjusted rotating rod 204, thereby preventing the rotating rod 204 from rotating due to external forces, reducing the probability of the arc plate 210 shifting, making the installation of the connecting block 212 more stable, and bringing convenience to the operator during use.
