Description

Technical Field

[0001] This invention relates to the field of ball screw processing technology, specifically to a CNC tapping device for ball screw processing. Background Technology

[0002] Ball screws are core components of precision transmission and are widely used in CNC machine tools, industrial robots, and various automated transmission equipment. Cyclone milling is an efficient machining method for ball screw thread processing. CNC cyclone milling machines rely on high-speed rotating milling cutter heads to mill the workpiece blank, resulting in high processing efficiency and good thread forming quality. It is widely used in the field of ball screw processing.

[0003] In the actual milling process of ball screws, existing CNC cyclone milling equipment still has many technical defects: First, the milling cutter mechanism on the traditional cyclone milling cutter disc generally adopts the installation form of multiple independent bolts for clamping and locking. When machining different specifications of ball screws and needing to change different milling cutter mechanisms, the operator needs to complete the disassembly and tightening of multiple sets of bolts one by one. The disassembly and assembly process is cumbersome and the tool changing auxiliary operation is time-consuming. Secondly, existing equipment generally only has simple fixed chip baffles and lacks a targeted chip guiding and removal structure. During cyclone milling, the high-speed rotating cutter head will use centrifugal force to throw metal chips and milling fluid outward at high speed. Chips and milling fluid will splash everywhere and are very likely to fall onto the machine tool's moving parts such as the base, Z-axis slide, and Y-axis slide. Small metal chips can easily enter the mating gaps of the guide rail pairs, causing guide rail scratches, movement jamming, and other equipment malfunctions. A large amount of chips are scattered in various parts of the machine tool, resulting in a large amount of subsequent equipment cleaning and maintenance work.

[0004] Therefore, this solution provides a CNC tapping machine for ball screw processing to solve the above problems. Summary of the Invention

[0011] Preferably, the side plate is fixedly connected to the guide block, the outer side of the side plate is fixedly connected to the limit block, the two ends of the limit block are fixedly connected to the limit rod, the limit rod is inserted into the guide plate, the limit rod is surrounded by a second spring, the second spring is located between the limit block and the guide plate, and the outer periphery of the guide plate is provided with multiple annular grooves.

[0012] Preferably, the guide plate extends through the side plate, and an arc plate is fixedly connected to one end of the guide plate, with the arc plate cooperating with a roller.

[0013] Preferably, the mounting block has an insertion hole that fits the outer periphery of the plug-in block, and the inner wall of the insertion hole has a slot that fits the plug-in block.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention features a cyclone milling mechanism with a built-in locking assembly.

[0017] This invention incorporates a chip guiding mechanism. During machining, a guide block is positioned outside the cyclone cutter head. The guide plate, guide block, and inner guide plate block and guide the centrifugally ejected milling fluid and metal chips, allowing the chips and milling fluid to be concentrated and guided into the machine tool chip collection tank. This prevents chips and milling fluid from splashing onto moving parts such as the base, Z-axis slide, and Y-axis slide, thus preventing metal chips from scratching the guide rail pair, reducing the risk of equipment failure, and simultaneously reducing scattered chips on the machine tool, thereby reducing the workload of daily cleaning and maintenance.

[0018] This invention directly utilizes the rotational power of the cyclone milling mechanism itself. Relying on the rollers on the snap-fit ​​assembly to circulate against the arc plate, and in conjunction with spring two, it drives the guide plate to perform reciprocating horizontal motion. The reciprocating motion of the guide plate, combined with the annular groove on it, can break up and disperse chips and milling fluid, preventing chips from concentrating and impacting local positions of the guide block, reducing local wear of the baffle, and extending the service life of the chip guiding mechanism parts. At the same time, it prevents chips from clumping together and further improves chip removal performance. Attached Figure Description

[0022] Example: Please refer to Figures 1-10 The present invention relates to a CNC tapping machine for ball screw machining, comprising a cyclone milling machine 1, wherein the cyclone milling machine 1 comprises a base 11 and an internal Z-axis slide 12, a tailstock 13, a Y-axis slide 14, an inclined mounting seat 15 and a cyclone milling seat 16, wherein a cyclone milling mechanism 2 is installed inside the cyclone milling mechanism 16, a ring-shaped milling cutter mechanism 3 is installed on one side of the cyclone milling mechanism 2, and a chip guiding mechanism 4 is installed on the outer side of the cyclone milling seat 16; The cyclone milling mechanism 2 includes a cyclone cutter disc 22 and a connecting ring 21 that are fixedly connected on the left and right sides. The cyclone milling mechanism 2 also includes a linkage disc 24, a block 25 and a snap-fit ​​assembly 26 inside the cyclone cutter disc 22. The snap-fit ​​assembly 26 includes a plug block 261 and a groove 262, as well as a top rod 263 that is slidably connected inside the groove 262.

The milling cutter mechanism 3 includes an integral mounting block 31 and a milling cutter head 32; The chip guiding mechanism 4 includes a receiving seat 41, a guide block 43 and a side plate 44.

Among them, the mounting block 31 and the milling cutter head 32 are existing cyclone cutter heads; the external part of the cyclone milling machine 1 is equipped with a CNC terminal, which can control the operation of other equipment.

[0023] In this embodiment, the connecting ring 21 is rotatably connected to the inside of the cyclone milling base 16, and an annular distribution slot 221 is provided on one side of the cyclone cutter disc 22. The plug block 261 is fixedly connected to the inside of the slot 221, and the milling cutter mechanism 3 fits into the inside of the slot 221. The milling cutter mechanism 3 can be quickly installed and removed from the slot 221 via the snap-fit ​​assembly 26, thereby improving replacement efficiency.

[0024] In this embodiment, a drive rod 23 is rotatably connected inside the cyclone cutter disc 22, and a toothed ring 241 and a planar spiral guide block 242 are fixedly connected to both sides of the linkage disc 24. The toothed ring 241 is engaged with the bottom end of the drive rod 23, and the block 25 is slidably connected inside the cyclone cutter disc 22. One side of the block 25 is engaged with the planar spiral guide block 242. The bottom end of the drive rod 23 is a bevel gear that meshes with the gear ring 241. In addition, the top end of the drive rod 23 can be driven to rotate by a hex wrench, which in turn drives the linkage disc 24 to rotate, thereby allowing the block 25 to move. The block 25 is oriented toward the central axis of the cyclone cutter disc 22.

[0025] In this embodiment, the top rod 263 is provided with a linkage plate 267 fixedly connected to both ends and a roller 264 rotatably connected to both ends. The linkage plate 267 cooperates with the block 25. Two connecting rods 265 are rotatably connected to both sides of the top rod 263. The other end of the connecting rod 265 is rotatably connected to the snap-fit ​​block 266. The snap-fit ​​block 266 is inserted into the snap-fit ​​assembly 26. A spring 268 is provided between the linkage plate 267 and the snap-fit ​​block 261. Among them, the four corners of the snap-fit ​​block 266 are fixedly connected with limit guide rods, which are inserted into the inside of the snap-fit ​​block 261. The outer periphery of the snap-fit ​​block 266 fits the insertion hole 33 and the slot 34 in a stepped shape. The spring 268 is used to push the linkage plate 267, along with the push rod 263 and the roller 264, into the cyclone cutter disc 22, so that the snap-fit ​​block 266 can be quickly pulled out from the slot 34 after the block 25 moves up.

[0026] In this embodiment, a cylinder 42 is rotatably connected to one side of the receiving seat 41, the top of the guide block 43 is rotatably connected to the receiving seat 41, the output end of the cylinder 42 is rotatably connected to the top of the guide block 43, and an inner guide plate 431 is fixedly connected to the bottom of both ends of the guide block 43. The inner walls of the guide block 43 and the inner guide plate 431 are provided with equally spaced guide grooves 432. Among them, the cylinder 42 is used to retract its output end when the milling cutter mechanism 3 needs to be replaced, so that the guide block 43 and the side plate 44 no longer cover the cyclone cutter head 22; the guide block 43 is inverted U-shaped, while the inner guide plate 431 guides its port inward and is bucket-shaped; the guide groove 432 is used to guide the milling fluid and chips.

[0027] In this embodiment, the side plate 44 is fixedly connected to the guide block 43, the outer side of the side plate 44 is fixedly connected to the limit block 47, the two ends of the limit block 47 are fixedly connected to the limit rod 49, the limit rod 49 is inserted into the guide plate 45, the outer periphery of the limit rod 49 is surrounded by a second spring 48, the second spring 48 is located between the limit block 47 and the guide plate 45, and the outer periphery of the guide plate 45 is provided with a plurality of annular grooves 451; Among them, the limiting block 47 is used to support the limiting rod 49. After the guide plate 45 passes through the side plate 44, it limits the guide plate 45 so that the guide plate 45 is always perpendicular to the side plate 44. The guide plate 45 is tilted inward at 45 degrees, so as to face the tangent of the cyclone cutter 22. There are only four guide plates 45. The multiple annular grooves 451 are distributed in a scattering manner to disperse debris.

[0028] In this embodiment, the guide plate 45 passes through the side plate 44, and an arc plate 46 is fixedly connected to one end of the guide plate 45. The arc plate 46 cooperates with the roller 264. The arc shape of the arc plate 46 allows the cyclone milling mechanism 2 to contact the arc plate 46 when it rotates with the roller 264, thereby allowing the guide plate 45 to perform reciprocating left and right movements.

[0029] In this embodiment, the mounting block 31 has an insertion hole 33 that fits the periphery of the insertion block 261, and the inner wall of the insertion hole 33 has a slot 34 that fits the insertion block 266. Among them, the cross-sections of the socket 33, the plug block 261 and the roller 264 at the rotation point are all rhomboid.

[0030] In this embodiment, the Z-axis slide 12 is installed inside the base 11, and the Y-axis slide 14 and the tailstock 13 are both slidably connected above the Z-axis slide 12. The base 11 also has an installation chuck inside for fixing one end of the ball screw, which can be used with the tailstock 13 to fix and clamp the blank rod at the left and right ends.

[0031] In this embodiment, the tilt mounting base 15 is slidably connected above the Y-axis slide block 14, and the cyclone milling base 16 is rotatably connected inside the tilt mounting base 15. One end of the Y-axis slide 14 is equipped with a drive motor, which can control the Y-axis movement of the tilt mounting base 15. A telescopic cylinder is installed on the outside of the tilt mounting base 15, which can control the tilt angle of the cyclone milling base 16, the cyclone milling mechanism 2, the milling cutter mechanism 3 and the chip guide mechanism 4. A drive motor is installed on the top of the cyclone milling base 16, which can be connected to the connecting ring 21 through the belt at the output end, so that the cyclone milling mechanism 2 rotates along with the milling cutter mechanism 3. Thus, together with the Z-axis slide 12 and the tailstock 13, it constitutes the CNC cyclone milling machine in the existing equipment.

[0032] The working principle of this invention is as follows: When it is necessary to process a ball screw, the blank rod can be positioned inside the base 11, so that the blank rod passes through the inside of the cyclone milling mechanism 2 and both ends are positioned by the chuck and tailstock 13 of the cyclone milling machine 1. Then, the tilt angle of the cyclone milling base 16 and the cyclone milling mechanism 2 is controlled by the cylinders on both sides of the tilt mounting base 15, and the position of the tilt mounting base 15 is controlled by the motor on one side of the Y-axis slide 14. Then, the motor above the cyclone milling base 16 can be started, so that the cyclone milling mechanism 2 can be driven to rotate by the belt at the output end of the motor. Finally, the blank rod is rotated by CNC while the Y-axis slide 14 moves the component above it in the Z direction, thus completing the processing of the blank rod into a ball screw. When it is necessary to produce ball screws of different diameters or different screw depths, the milling cutter mechanism 3 can be placed inside the slot 221 and the insertion block 261 can be passed through the insertion hole 33. Then, the drive rod 23 can be connected by an external tool to make the linkage plate 24 rotate, thereby causing the block 25 to slide towards the center of the cyclone cutter disc 22. At this time, the linkage plate 267, the push rod 263 and the roller 264 will be pushed outward, so that the outer side of the locking block 266 can be locked into the inside of the slot 34 through the connecting rod 265. This allows for quick locking and unlocking of the cutter head in the slot 221, making replacement more convenient and faster. Furthermore, when the motor above the cyclone milling head 16 operates, the cylinder 42 operates synchronously, causing the guide block 43 to rotate downwards along with the side plate 44 until the guide block 43 is parallel to the cyclone cutter head 22. At this point, the guide block 43 will cover the periphery of the cyclone cutter head 22. When the cylinder 42 stops operating, and the cyclone milling mechanism 2 performs clockwise cyclone milling on the blank rod, the milling fluid and debris will be thrown outwards by the centrifugal force of the cyclone cutter head 22, and then initially blocked by the guide plate 45 on the inner side of the guide block 43. Furthermore, since the guide plate 45 has an inclined angle and faces the tangent of the cyclone cutter head 22, the centrifugal milling fluid and chips can be initially blocked and guided by the guide plate 45 and then impact the inner wall of the guide block 43 along the tangent direction. After being guided by the guide groove 432 of the guide block 43 and the inner wall of the inner guide plate 431, they are concentrated in the chip collection groove between the Z-axis slide 12. This can prevent the milling fluid and chips from being thrown outside the collection groove of the cyclone milling machine 1 itself during the cyclone milling process, so that they can be collected more conveniently. Furthermore, during the rotation of the cyclone milling mechanism 2, the locking assembly 26 also rotates, causing the roller 264 to continuously abut against the arc plate 46, causing the guide plate 45 to move horizontally. Since the other end of the guide plate 45 has a spring 48, the cyclone milling mechanism 2 drives the guide plate 45 to reciprocate left and right during high-speed rotation. In conjunction with the dispersed annular grooves 451 on the periphery of the guide plate 45, the guide plate 45 can evenly disperse the milling fluid and chips during the initial guiding process, thereby preventing the milling fluid and chips from concentrating in one place and impacting the inner wall of the guide block 43, extending its service life. At the same time, it can also disperse the milling fluid and chips so that they do not accumulate when they are guided into the collection tank of the cyclone milling machine 1.

[0033] The cyclone milling machine 1 and cylinder 42 used in this invention are both existing known electrical devices, and both can be purchased and used directly on the market. Their structure, circuit and control principle are all existing known technologies. Therefore, the structure, circuit and control principle of the cyclone milling machine 1 and cylinder 42 will not be described in detail here.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art and are also general components, which are common knowledge in this field.
