Description

Technical Field

[0001] This invention relates to the field of machine tool processing technology, and in particular to an integrated composite machining tool. Background Technology

[0002] As an important branch of machine tools, CNC lathes require advanced development to meet the needs of modern production, namely, machining complex, high-precision workpieces and improving machining efficiency. Therefore, the development of tool changing systems is crucial. The tool turret, a key component of the tool changing system, effectively expands the machine tool's technological range, improves machining efficiency, and reduces human error. Consequently, the design of the tool turret and the study of its performance are of paramount importance.

[0003] However, existing machine tool turrets generally have certain shortcomings. The tools on the turret are mostly fixed one by one with bolts, which is inefficient. Furthermore, when maintenance is required later, they need to be removed one by one, which is also inefficient. In other words, the overall disassembly and assembly efficiency is low, which is not conducive to the initial installation and the later maintenance process. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an integrated composite machining tool that uses a locking disc and a locking mechanism to lock and fix the cutting tool, effectively improving the efficiency of tool assembly and disassembly, and aiming to solve the problems in the background technology.

[0005] To achieve the above technical objectives, the specific technical solution of the present invention is as follows: The present invention proposes an integrated composite machining center, comprising a machine body, a spindle box, and a tool processing mechanism. A three-jaw chuck is fixedly mounted on the spindle box shaft for fixing the workpiece. An X-axis drive mechanism and a Y-axis drive mechanism are mounted on the machine body for driving the tool processing mechanism to move along the X-axis and Y-axis, respectively. The tool processing mechanism includes a turret box, a turret plate, a drive motor for rotating the turret plate, and multiple tools mounted on the circumference of the turret plate, wherein the tools are fixedly mounted on tool holders. The turret box has a rotating shaft, and the turret plate is fixedly mounted on the rotating shaft. The circumference of the turret plate has multiple mounting slots, and the tool holders are fixedly mounted in the mounting slots. A locking disc is threadedly connected to the rotating shaft, and multiple locking mechanisms are connected to the locking disc for locking and fixing the tool holders in the mounting slots.

[0006] Furthermore, the locking mechanism includes a V-shaped locking frame, with a pair of pressure rods symmetrically fixedly connected to both ends of the locking frame, and a locking block slidably connected to the end of each pressure rod.

[0007] Furthermore, the inner walls on both sides of the mounting groove are provided with receiving grooves that are slidably connected to the locking block, and the two sides of the mounting groove are provided with guide holes that are slidably connected to the pressure rod, with one end of the guide hole extending into the receiving groove.

[0008] Furthermore, the locking block has an inclined groove on one side, the pressure rod has an inclined block that is slidably connected to the inclined groove, the locking block has a locking part with a trapezoidal structure, and the side of the tool holder has a locking groove that cooperates with the locking part.

[0009] Furthermore, a pressure seat is fixedly connected to one end of the locking frame, and an arc-shaped sliding groove is provided on the side of the pressure seat. An extrusion block corresponding to the locking mechanism is fixedly connected to the locking plate. The extrusion block is arc-shaped and slides with the sliding groove. The thickness of the extrusion block gradually increases from one end to the other along its circumference.

[0010] Furthermore, a pressure block is fixedly connected to the inner side of the locking frame for pressing and fixing the tool holder; a threaded post is fixedly connected to the locking frame, and an L-shaped frame that mates with the threaded post is fixedly connected to the pressure block, and a pair of adjusting nuts are threadedly connected to the threaded post.

[0011] Furthermore, a pair of threaded rods are fixedly connected to the back of the turret disc, and a limit block is fixedly connected to the threaded rod for limiting and fixing the locking disc. The limit block is provided with a limit groove, and a locking nut for locking the limit block is threadedly connected to the threaded rod.

[0012] Furthermore, the locking disc is provided with a slot that cooperates with the limiting block, and the center of the locking disc is provided with a threaded sleeve that is threadedly connected to the rotating shaft.

[0013] Furthermore, the machine body is provided with a waste trough, which is located below the three-jaw chuck.

[0014] The beneficial effects of this invention are as follows: 1. This invention features a locking disc and multiple locking mechanisms. Rotating the locking disc drives the locking mechanisms to move, thus fixing the cutting tools one by one onto the turret disc. This allows for simultaneous installation and removal of the cutting tools, making the installation and removal of the tools more convenient and facilitating the later maintenance of the machine tool.

[0015] 2. The locking mechanism of the present invention is provided with a pressure rod, a locking block and a pressure block. When the locking disc drives the locking mechanism to move, the locking block presses the two sides of the tool holder, and the pressure block presses one end of the tool holder, thereby pressing and fixing the tool holder in all directions. The tool holder is installed stably and is easy to disassemble. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] This embodiment discloses an integrated composite machining tool, such as Figures 1-8As shown, the machine includes a body 1, a spindle box 101, and a tool processing mechanism 2. A three-jaw chuck 102 is fixedly mounted on the spindle box 101 to fix the workpiece. An X-axis drive mechanism 3 and a Y-axis drive mechanism 4 are mounted on the body 1 to drive the tool processing mechanism 2 to move along the X-axis and Y-axis, respectively. Both the X-axis drive mechanism 3 and the Y-axis drive mechanism 4 adopt the drive method of a motor driving a lead screw, which is the existing technology. The tool processing mechanism 2 includes a turret box 21, a turret plate 23, a drive motor 22 for rotating the turret plate 23, and multiple tools 27 mounted on the circumference of the turret plate 23. The tools 27 include milling cutters, drills, grinding tools, etc. The tools 27 are fixedly mounted on a tool holder 271. The workpiece is processed in an integrated composite manner by using different types of tools 27 to improve processing efficiency.

[0027] Preferably, the machine body 1 is provided with a waste trough 103, which is located below the three-jaw chuck 102 and is used to receive waste generated during workpiece processing.

[0028] like Figures 2-4 As shown, the turret box 21 is provided with a rotating shaft 26, and the turret plate 23 is fixedly installed on the rotating shaft 26 by bolts. The turret plate 23 has a plurality of mounting slots 231 for mounting tools 27 on its circumference. A locking plate 24 is threadedly connected to the rotating shaft 26. The rotating shaft 26 has a threaded line on its surface. The locking plate 24 has a threaded sleeve 243 at its center that is threadedly connected to the rotating shaft 26. A plurality of locking mechanisms 25 are connected to the locking plate 24. Each locking mechanism 25 corresponds to a tool 27. The locking mechanism 25 is used to lock and fix the tool holder 271 in the mounting slot 231.

[0029] like Figure 5-7As shown, the locking mechanism 25 includes a V-shaped locking frame 251. A pair of pressure rods 254 are symmetrically fixed to both ends of the locking frame 251, and locking blocks 255 are slidably connected to the ends of the pressure rods 254. The inner walls of both sides of the mounting groove 231 are provided with receiving grooves 232 that slidably connect with the locking blocks 255. Guide holes 233 that slidably connect with the pressure rods 254 are provided on both sides of the mounting groove 231, with one end of the guide hole 233 extending into the receiving groove 232. One side of the locking block 255 is provided with an inclined groove 256, and the pressure rod 254 is provided with an inclined block 257 that slidably connects with the inclined groove 256. When the inclined block 257 slides within the inclined groove 256, it will lock the mechanism. Block 255 slides within the receiving groove 232, and locking block 255 is provided with a trapezoidal locking part 2511. The width of tool holder 271 is adapted to the width of mounting groove 231, allowing for sliding assembly. The side of tool holder 271 is provided with a locking groove 272 that mates with locking part 2511. When locking bracket 251 moves toward the turret 23, it drives pressure rod 254 to slide within guide hole 233, causing inclined block 257 to slide within inclined groove 256, which in turn drives locking block 255 to slide within receiving groove 232. Locking part 2511 is inserted into locking groove 272, locking and fixing both sides of tool holder 271 to prevent tool wobbling.

[0030] Preferably, a pressure seat 252 is fixedly connected to one end of the locking frame 251. The pressure seat 252 has an arc-shaped groove 253 on its side. An extrusion block 241 corresponding to the locking mechanism 25 is fixedly connected to the locking disc 24. The extrusion block 241 has an arc-shaped strip structure and slides with the groove 253. The thickness of the extrusion block 241 gradually increases along the circumference. The thickness of the extrusion block 241 refers to the thickness along the central axis of the locking disc 24. When the locking disc 24 rotates in the forward direction, the extrusion block 241 rotates in the groove 253. The extrusion block 241 rotates from the thinner end to the thicker end, and the thickness of the extrusion block 241 gradually increases. The surface of the extrusion block 241 continuously extrudes the pressure seat 252, thereby driving the locking frame 251 to move closer to the turret disc 23, thereby locking and fixing the tool 27.

[0031] Preferably, a pressure block 258 is fixedly connected to the inner side of the locking frame 251 for pressing and fixing the tool holder 271; a threaded post 259 is fixedly connected to the locking frame 251, and an L-shaped frame 2512 that mates with the threaded post 259 is fixedly connected to the pressure block 258, and a pair of adjusting nuts 2510 are threadedly connected to the threaded post 259. The adjusting nuts 2510 are located on both sides of the L-shaped frame 2512. The position of the pressure block 258 is finely adjusted by adjusting the nuts 2510 to ensure that each tool is pressed; when the locking frame 251 moves towards the turret 23, the locking block 255 locks and fixes both sides of the tool, and at the same time, the pressure block 258 presses and fixes one end of the tool, thereby locking the tool 27 in all directions and ensuring the stability of the tool.

[0032] Preferably, a pair of threaded rods 234 are fixedly connected to the back of the turret disc 23. A limit block 235 is fixedly connected to the threaded rod 234 for limiting and fixing the locking disc 24. The limit block 235 is provided with a limit groove 236. A locking nut 237 for locking the limit block 235 is threadedly connected to the threaded rod 234. The locking disc 24 is provided with a slot 242 that mates with the limit block 235. The locking disc 24 is also provided with a handle for easy rotation. The axial position of the locking disc 24 is limited by the limit block 235. At the same time, the threaded connection between the locking disc 24 and the rotating shaft 26 ensures the stability of the axial and circumferential positions of the locking disc 24, prevents the locking disc 24 from rotating on its own, and ensures the locking effect on each tool 27.

[0033] Working principle: This invention rotates the locking disc 24, causing the locking frame 251 to move closer to the turret disc 23. During the movement of the locking frame 251, the locking block 255 locks and fixes both sides of the tool holder 271, and the pressure block 258 presses and fixes one end of the tool holder 271, thereby limiting the tool holder 271 in different directions and ensuring the stability of the tool holder 271. Furthermore, the axial position of the locking disc 24 is limited by the limiting block 235, and the locking nut 237 limits and fixes both sides of the limiting block 235, ensuring the axial position of the locking disc 24. The stability of the directional and circumferential positions prevents the locking disc 24 from rotating on its own. Similarly, when the tool 27 needs to be disassembled for maintenance, first loosen the locking nut 237, then rotate the locking disc 24 in the opposite direction to move the locking mechanism 25 away from the turret disc 23, and then remove the tool 27 from the mounting slot 231. Compared with the prior art, this embodiment allows multiple tools 27 to be locked and fixed simultaneously by the locking disc 24 and the locking mechanism 25, enabling the simultaneous installation and removal of multiple tools 27. The installation and removal of the tools 27 are more convenient and conducive to the maintenance of the machine tool.
