Technical Field

[0001] This invention relates to the field of machining technology, specifically to a dual-head coaxial boring and milling machining device. Background Technology

[0002] Boring and milling machines are commonly used machining equipment. They are machine tools that use milling cutters to mill workpieces. In addition to milling planes, grooves, gear teeth, threads, and splined shafts, milling machines can also process relatively complex profiles. They are more efficient than planers and are widely used in mechanical manufacturing and repair departments. Double-headed coaxial boring and milling equipment is often used to process both sides of a workpiece simultaneously, providing good synchronization.

[0003] In the prior art, when machining a workpiece with a dual-head coaxial boring and milling machine, the machining is usually carried out in a splash guard to avoid the flying of chips. However, even in this way, the chips will still be scattered inside the splash guard, which is inconvenient for workers to clean and collect. Moreover, chips usually remain inside the workpiece, which also requires workers to clean them later, making it difficult to meet the needs of workers. Summary of the Invention

Detailed Implementation

[0018] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] Example 1 Please refer to Figures 1-13 As shown, a dual-head coaxial boring and milling machining device includes a base plate 1. The top of the base plate 1 is connected to a worktable 101 via an inclined assembly. A clamping mechanism 2 for fixing a rod-shaped workpiece is installed on the top of the worktable 101. An adjustment mechanism 3 for connecting two sets of collection boxes 107 is provided on the rear side of the clamping mechanism 2. A machining mechanism 4 is installed inside the collection box 107. Storage mechanisms 5 are provided on both sides of the top of the base plate 1. A drill bit 108 and a baffle plate 109 are placed inside the storage mechanism 5. A robotic arm 106 for loading and unloading rod-shaped workpieces is installed on the top of the worktable 101.

[0020] Example 2 Please refer to Figure 3As shown, the clamping mechanism 2 includes a first fixed frame 201 fixedly installed on the top of the workbench 101. A first threaded rod 202 is rotatably connected inside the first fixed frame 201. Both ends of the first threaded rod 202 are threadedly connected to movable plates 205. Both sets of movable plates 205 are slidably connected to the outer wall of the first fixed rod 203. The first fixed rod 203 is welded inside the first fixed frame 201. A first servo motor 204 is installed on the outside of the first fixed frame 201. The outer end of the first threaded rod 202 is fixedly connected to the output end of the first servo motor 204, and the threads at both ends of the first threaded rod 202 are in opposite directions.

[0021] Please refer to Figure 3 As shown, the clamping mechanism 2 also includes two sets of double-headed electric cylinders 206. The two sets of double-headed electric cylinders 206 are respectively fixedly installed inside the two sets of movable plates 205. Both output ends of the double-headed electric cylinders 206 can be detachably connected to clamping parts 207. The clamping parts 207 are provided with sealing grooves 208.

[0022] Those skilled in the art will understand that the first threaded rod 202 is rotated by the output end of the first servo motor 204, causing the two sets of movable plates 205 to move closer or further apart, thereby causing the two sets of clamping members 207 on the left and right sides to move closer or further apart; and by controlling the two output ends of the double-headed electric cylinder 206 to extend and retract synchronously, the two sets of clamping members 207 connected to it can move closer to each other to a close fit state. Since the clamping members 207 are detachably connected to the output ends of the double-headed electric cylinder 206, when fixing rod-shaped workpieces of different outer diameters, the present invention can replace the appropriate clamping members 207, so that the two sets of clamping members 207 on the same side can wrap the outer wall of the rod-shaped workpiece.

[0023] Example 3 Please refer to Figure 4 As shown, the adjustment mechanism 3 includes a second fixed frame 301, a second threaded rod 302, and a movable part 305. The second fixed frame 301 has two sets of parts welded to the top rear side of the workbench 101. The second threaded rod 302 is rotatably connected inside the second fixed frame 301. The movable part 305 is threadedly connected to the outer wall of the second threaded rod 302. A second fixed rod 303 is also fixedly installed inside the second fixed frame 301. The movable part 305 is slidably connected to the second fixed rod 303. The outer ends of the two sets of second threaded rods 302 are respectively fixedly installed at the two output ends of the dual-axis motor 304. The dual-axis motor 304 is located on the top rear side of the workbench 101. A motor is installed on the top of the horizontal plate of the movable part 305. The rear side of the collection box 107 is fixedly installed on the output end of the motor. A sealing ring that matches the sealing groove 208 is provided at the opening of the collection box 107.

[0024] Those skilled in the art will understand that by controlling the synchronous rotation of the two output ends of the dual-axis motor 304, the second threaded rods 302 on both sides rotate synchronously, causing the two sets of moving parts 305 to move closer or further apart. When they move closer, the two sets of collection boxes 107 can be moved closer together, so that the sealing rings on the two sets of collection boxes 107 can be respectively locked inside the sealing grooves 208 on both sides to achieve sealing.

[0025] Example 4 Please refer to Figure 5 As shown, the processing mechanism 4 includes a first sleeve 401 rotatably connected inside the collection box 107. A second sleeve 402, a third sleeve 403, and a fourth sleeve 404 are slidably connected inside the first sleeve 401. A fixing disk 405 is fixedly connected to the outer end of the fourth sleeve 404. Telescopic components are provided inside the first sleeve 401, the second sleeve 402, the third sleeve 403, and the fourth sleeve 404. An installation component is provided inside the fixing disk 405. The installation component is used to fix the drill bit 108 or the baffle plate 109. A driven gear 408 is fixedly connected to the outer wall of the first sleeve 401. The driven gear 408 is meshed with a drive gear 407. A first drive motor 406 is installed on the outside of the collection box 107. The drive gear 407 is fixedly installed on the output end of the first drive motor 406.

[0026] Those skilled in the art will understand that the telescopic assembly allows the second sleeve 402, the third sleeve 403, and the fourth sleeve 404 to extend or retract sequentially from or into the first sleeve 401, thereby moving the fixed disk 405 closer to or further away from the end of the clamped rod-shaped workpiece. This, in turn, causes the drill bit 108 to move closer to or further away from the end of the clamped rod-shaped workpiece. Furthermore, the output of the first drive motor 406 drives the drive gear 407 to rotate, causing the meshing driven gear 408 to rotate, which in turn rotates the first sleeve 401, thus rotating the drill bit 108. In summary, if the drill bit 108 rotates while simultaneously approaching the end of the rod-shaped workpiece, drilling can be performed on the end of the workpiece.

[0027] Please refer to Figure 7 , Figure 8 and Figure 9 As shown, the telescopic assembly includes a first lead screw 409 and a first guide rod 410. An installation groove is provided on the inner wall of the first sleeve 401. The first lead screw 409 is rotatably connected to the installation groove, and the first guide rod 410 is fixedly connected to the installation groove. A movable plate 412 is slidably connected to the outer wall of the first guide rod 410. The movable plate 412 is threadedly connected to the first lead screw 409. A first stepper motor 411 is installed on the outer side of the first sleeve 401, and the outer end of the first lead screw 409 is fixedly connected to the output end of the first stepper motor 411.

[0028] Please refer to Figure 9 and Figure 10 As shown, the telescopic assembly also includes a scissor-type telescopic component 414. Two sets of first movable blocks 413 are slidably connected to the inner wall of the first sleeve 401. One end of the scissor-type telescopic component 414 is rotatably connected to the two sets of first movable blocks 413 respectively. The other end of the scissor-type telescopic component 414 is rotatably connected to the two sets of second movable blocks 416 respectively. The two sets of second movable blocks 416 are slidably connected to the inner wall of the fourth sleeve 404. A strip groove 415 is provided through the middle of the moving plate 412. The pin on the scissor-type telescopic component 414 is rotatably connected to the inner wall of the strip groove 415. Sliding grooves 418 are provided on the inner walls of the second sleeve 402, the third sleeve 403 and the fourth sleeve 404. A sliding rod 417 is also provided on the scissor-type telescopic component 414. The outer end of the sliding rod 417 is slidably connected to the sliding groove 418.

[0029] Those skilled in the art will understand that by driving the first lead screw 409 to rotate through the output end of the first stepper motor 411, the moving plate 412 is driven to reciprocate left and right along the outer wall of the first guide rod 410, causing the scissor-type telescopic member 414 to be in an extended or retracted state. When the scissor-type telescopic member 414 is in an extended state, the two sets of first movable blocks 413 and the two sets of second movable blocks 416 are all in a close-to-each-other state, thereby realizing that the second sleeve 402, the third sleeve 403 and the fourth sleeve 404 extend out from the first sleeve 401 in sequence. Conversely, when the scissor-type telescopic component 414 is in the retracted state, the two sets of first movable blocks 413 and the two sets of second movable blocks 416 are all in a state of mutual distance, thereby realizing that the second sleeve 402, the third sleeve 403 and the fourth sleeve 404 retract into the first sleeve 401 in sequence. In summary, it can drive the fixed plate 405 to approach or move away from the end of the clamped rod-shaped workpiece. Moreover, through the cooperation of the sliding rod 417 and the sliding groove 418, the stability of the movement of the second sleeve 402, the third sleeve 403 and the fourth sleeve 404 is improved. The telescopic component in this invention is a multi-stage telescopic structure, which can provide a greater range of motion for the fixed disk 405 when it is extended. Therefore, it is well-suited for processing long rod-shaped workpieces, thus improving the applicability of the device.

[0030] Please refer to Figure 7 and Figure 11As shown, the mounting assembly includes a rotating gear ring 419 rotatably connected inside a fixed disk 405. A set of first gears 420 and several sets of second gears 421 are also rotatably connected inside the fixed disk 405. The outer teeth of the rotating gear ring 419 mesh with the first gears 420, and the inner teeth of the rotating gear ring 419 mesh with several sets of second gears 421. A second drive motor 423 is fixedly connected to the inner wall of the fixed disk 405. The output end of the second drive motor 423 is fixedly connected to the first gears 420. Several sets of clamping plates 422 are also slidably connected inside the fixed disk 405. Each set of clamping plates 422 is equipped with a toothed plate, and the toothed plates mesh with several sets of second gears 421 respectively.

[0031] Those skilled in the art will understand that the first gear 420 is driven to rotate by the output end of the second drive motor 423, causing the rotating gear ring 419 to rotate within the fixed disk 405, which in turn drives all the second gears 421 to rotate synchronously. This causes all the gear plates to move synchronously toward or away from the center of the fixed disk 405, thereby enabling all the clamping plates 422 to move synchronously toward or away from the center of the fixed disk 405. When they are close, they can clamp the outer wall of the rod portion of the drill bit 108 or the shielding plate 109, and when they are far away, they can release the clamping.

[0032] Example 5 Please refer to Figure 12 As shown, the storage mechanism 5 includes a support plate 501 and a frame 502. The support plate 501 and the frame 502 are respectively fixedly installed on the left and right sides of the top of the workbench 101. A second lead screw 503 is rotatably connected inside the frame 502. A lifting plate 506 is threadedly connected to the second lead screw 503. The lifting plate 506 is slidably connected to the second guide rod 504. The second guide rod 504 is fixedly connected inside the frame 502. The top of the second lead screw 503 is fixedly connected to the output end of the second stepper motor 505. The second stepper motor 505 is located on the top of the frame 502. A third drive motor 507 is installed on the outer side of both the support plate 501 and the lifting plate 506. A storage tray 508 is fixedly connected to the output end of the third drive motor 507. Drill bits 108 are evenly installed on the two sets of storage trays 508. A baffle plate 109 is also installed at the center of the right storage tray 508.

[0033] Those skilled in the art will understand that the output of the second stepper motor 505 drives the second lead screw 503 to rotate, causing the lifting plate 506 to move up and down along the outer wall of the second guide rod 504, thereby driving the storage tray 508 on the right side to move up and down. When the storage trays 508 on both sides are at the same height, that is, when their centers are at the same height, the center of the drill bit 108 at the bottom of the storage trays 508 on both sides is on the same plane as the center of the fixed plate 405 on both sides.

[0034] Example 6 Please refer to Figure 2 As shown, the tilting assembly includes a first fixed seat 102, a second fixed seat 103, and a third fixed seat 105. The first fixed seat 102 is fixedly installed on the top left side of the base plate 1. The bottom rod of the worktable 101 is rotatably connected inside the first fixed seat 102. The second fixed seat 103 has two sets welded to the top of the base plate 1, and the third fixed seat 105 also has two sets welded to the bottom of the worktable 101. A cylinder 104 is rotatably connected inside the second fixed seat 103, and the output end of the cylinder 104 is rotatably connected inside the third fixed seat 105.

[0035] Those skilled in the art will understand that by controlling the extension or retraction of the output end of the cylinder 104, the bottom rod at the bottom of the worktable 101 is rotated within the first fixed seat 102, thereby allowing the worktable 101 to remain in an inclined or horizontal state.

[0036] To clearly describe the working principle of this invention, we will use... Figure 1 This is an explanation of the directional perspective, specifically referring to the "up, down, left, right, front, and back" as mentioned below, as follows: S1. The staff selects the clamping part 207 according to the outer diameter of the rod-shaped workpiece to be processed on the production line and fixes it on the output end of the double-headed electric cylinder 206. The robotic arm 106 clamps the rod-shaped workpiece to be processed on the end of the external conveyor and transfers it to the clamping mechanism 2. The rod-shaped workpiece is in a horizontal state. S2. The output end of the first servo motor 204 drives the first threaded rod 202 to rotate, causing the two sets of movable plates 205 to move closer or further apart, thereby causing the two sets of clamping parts 207 on the left and right sides to move closer or further apart, so that the outer walls of the two sets of clamping parts 207 on the left and right sides are flush with the outer walls of both ends of the rod-shaped workpiece. Then, by controlling the two output ends of the double-headed electric cylinder 206 to extend and retract synchronously, the two sets of clamping parts 207 connected to it can move closer to each other to a close fit, so that the two sets of clamping parts 207 on the same side can wrap the outer wall of the rod-shaped workpiece. S3. By controlling the synchronous rotation of the two output ends of the dual-axis motor 304, the second threaded rods 302 on both sides rotate synchronously, driving the two sets of moving parts 305 to move closer to each other, thereby driving the two sets of collection boxes 107 to move closer to each other, so that the sealing rings on the two sets of collection boxes 107 can be respectively stuck inside the sealing grooves 208 on both sides to achieve sealing. S4. With the combined action of the telescopic component and the output end of the first drive motor 406, the drill bits 108 on both sides move closer to the end of the rod-shaped workpiece while rotating, thus enabling simultaneous drilling of both ends of the rod-shaped workpiece, which speeds up the drilling efficiency. In addition, the telescopic component in this invention is a multi-stage telescopic structure, which can provide a greater movement process for the drill bits 108 when it is extended. Therefore, it is well-suited for processing long rod-shaped workpieces, which improves the applicability of the device. S5. Since collection boxes 107 are provided on both sides, and the bottom of the collection box 107 near the rod-shaped workpiece has an inclined surface, the debris generated during processing will slide down the inclined surface into the collection box 107 for collection, preventing it from splashing into the external environment and meeting the needs of the workers. It is worth noting that some debris will still remain inside the drilled hole of the rod-shaped workpiece. Therefore, the output end of the right side of the dual-axis motor 304 is rotated, causing the right collection box 107 to move away from the right end of the rod-shaped workpiece. Then, the motor on the right movable part 305 is rotated, causing the collection box 107 to move away from the right end of the rod-shaped workpiece. The machine rotates slowly so that the opening of the collection box 107 faces the storage tray 508 on the right. Then, under the action of the telescopic component, the drill bit 108 fixed in the fixed plate 405 is pushed forward and put back into the storage tray 508 on the right, and the clamping is released. Then, under the action of the output end of the second stepper motor 505, the storage tray 508 on the right moves downward, which drives the baffle plate 109 in the storage tray 508 to move downward as well, so that the center of the baffle plate 109 is concentric with the center of the fixed plate 405 on the right. After that, the mounting component in the fixed plate 405 on the right clamps the baffle plate 109. S6. Under the rotation of the right output end of the dual-axis motor 304, the sealing ring on the right collection box 107 is re-engaged and locked in the sealing groove 208. Then, under the action of the telescopic component, the baffle plate 109 blocks the right end opening of the rod-shaped workpiece. Next, the output end of the control cylinder 104 extends, which drives the bottom rod of the worktable 101 to rotate in the first fixed seat 102, thereby keeping the worktable 101 in an inclined state. This keeps the rod-shaped workpiece in an inclined state, and the debris inside the rod-shaped workpiece slides down into the left collection box 107 for collection under the action of gravity. Due to the presence of the baffle plate 109, even if the right collection box 107 is also in an inclined state, the debris inside the right collection box 107 will not enter the rod-shaped workpiece again through the right opening, thus meeting the needs of the workers.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention. The scope of protection claimed by the appended claims and their equivalents is defined.
