Description

Technical Field

[0001] This invention relates to the field of injection molding machine screw processing technology, specifically to a high-precision integrated turning, milling, and grinding machine for the tail end of an injection molding machine screw. Background Technology

[0002] The injection screw is an important component of the injection molding machine. Its function is to convey, compact, melt, stir and pressurize the plastic. All of these are accomplished by the rotation of the screw inside the barrel. In the production and processing of injection screws, the outer wall of the screw is first tapped to form a threaded section, and then the threaded section is finely polished.

[0003] Currently, when processing injection molding screws, most existing devices typically only clamp one end of the workpiece, exposing the tail. However, this method makes the workpiece susceptible to centrifugal force, which affects the accuracy of thread milling and reduces the processing efficiency and quality of the injection molding screw. In addition, the "waste chips" generated during processing are prone to splashing, making it inconvenient for workers to clean and collect, and failing to meet the needs of workers. Summary of the Invention

Detailed Implementation

[0039] 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.

[0040] Example 1

[0041] Please refer to Figures 1-13 As shown, a high-precision milling and turning machine for the screw tail of an injection molding machine includes a machine body 1. A robotic arm 101 for loading and unloading is installed on the front top of the machine body 1. A fixed frame 102 is welded to the left top of the machine body 1. A rotating frame 104 is rotatably connected inside the fixed frame 102. A first drive motor 103 for driving the rotating frame 104 to rotate is provided on the front side of the fixed frame 102. The top of the rotating frame 104 is connected to a sliding frame 105 through a moving mechanism 2. The sliding frame 105 is slidably connected to the outer wall of the rotating frame 104. A blocking frame 107 is rotatably connected to the right end of the sliding frame 105. A second drive motor 106 for driving the blocking frame 107 to rotate is installed on the outside of the sliding frame 105. A left-end clamping mechanism 3 is provided on the left side inside the rotating frame 104. A processing mechanism 4 and a limiting mechanism are installed on the right side inside the sliding frame 105. A storage mechanism 5 and a detection mechanism 6 are also installed on the top of the machine body 1. A waste collection box 111 is provided on the right side of the machine body 1.

[0042] Example 2

[0043] Please refer to Figure 2 and Figure 3As shown, the moving mechanism 2 includes a first fixed block 201 welded to the top left side of the rotating frame 104. The right side of the first fixed block 201 is fixedly connected to the connecting block 203 via a first guide rod 202. A first lead screw 204 is rotatably connected between the connecting block 203 and the first fixed block 201. A first stepper motor 205 for driving the first lead screw 204 to rotate is provided on the outside of the first fixed block 201. A movable block 206 is threadedly connected to the first lead screw 204. The bottom of the movable block 206 is welded to the sliding frame 105. The movable block 206 is slidably connected to the first guide rod 202.

[0044] Those skilled in the art will understand that the first lead screw 204 is rotated by the output end of the first stepper motor 205, causing the movable block 206 to reciprocate left and right, thereby causing the sliding frame 105 to reciprocate left and right along the outer wall of the rotating frame 104.

[0045] Example 3

[0046] Please refer to Figure 3 and Figure 4 As shown, the left-end clamping mechanism 3 includes a fourth drive motor 308, which is installed on the left side of the rotating frame 104. The output end of the fourth drive motor 308 extends into the rotating frame 104 and is fixedly connected to the first rotating plate 301. Several sets of mounting slots are provided on the right side of the first rotating plate 301. A second lead screw 302 is rotatably connected inside the mounting slot. A second guide rod 303 is also fixedly installed inside the mounting slot. A second clamping member 307 is slidably connected to the second guide rod 303. The second clamping member 307 is threadedly connected to the second lead screw 302, and the outer end of the second lead screw 302 extends to the outside of the mounting slot and is fixedly connected to the driven gear 304. An end face gear 305 is also rotatably connected to the circumferential surface of the first rotating plate 301. A third drive motor 306 is fixedly installed on the first rotating plate 301. The middle part of the outer end of one set of driven gears 304 is fixedly connected to the output end of the third drive motor 306.

[0047] Those skilled in the art will understand that the output of the third drive motor 306 drives one set of driven gears 304 to rotate, causing the end face gear 305 to rotate, which in turn drives all the second lead screws 302 to rotate synchronously. Consequently, all the second clamping members 307 move synchronously toward a position closer to the center of the first rotating plate 301 or away from the center of the first rotating plate 301, thereby achieving workpiece clamping or unclamping. Furthermore, the output of the fourth drive motor 308 drives the first rotating plate 301 to rotate, thereby driving the workpiece in the clamped state to rotate.

[0048] Example 4

[0049] Please refer to Figure 3As shown, the limiting mechanism includes a first electric push rod 108, which is fixedly installed at the bottom of the inner side of the shielding frame 107. The output end of the first electric push rod 108 is fixedly connected to a first double-headed cylinder 109, and both output ends of the first double-headed cylinder 109 are fixedly connected to the first clamping member 110.

[0050] Those skilled in the art will understand that by controlling the extension or retraction of the output end of the first electric push rod 108, the first double-headed cylinder 109 and the two sets of first clamping members 110 can move to the left or to the right as a whole; and by controlling the extension or retraction of the two output ends of the first double-headed cylinder 109, the two sets of first clamping members 110 can be driven to move away from or closer to each other, and when they are close together, the outer wall of the workpiece can also be clamped.

[0051] Example 5

[0052] Please refer to Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the processing mechanism 4 includes a second rotating plate 401, which is rotatably connected to the inside of the shielding frame 107. A connecting tooth 402 is fixedly installed on the outer end of the second rotating plate 401. A fifth drive motor 404 is provided on the inner wall of the shielding frame 107. The connecting tooth 402 meshes with a drive tooth 403, which is fixedly installed on the output end of the fifth drive motor 404. A second stepper motor 405 is connected to the inner wall of the second rotating plate 401, and a third lead screw is installed on the output end of the second stepper motor 405. 406, a lifting block 408 is threadedly connected to the third lead screw 406. The lifting block 408 is slidably connected to the third guide rod 407. The third guide rod 407 is welded inside the second rotating plate 401. A multi-stage electric telescopic rod 409 is fixedly connected to the left side of the lifting block 408. A moving plate 410 is fixedly connected to the sliding rod at the end of the multi-stage electric telescopic rod 409. When the multi-stage electric telescopic rod 409 is fully extended, the length of the multi-stage electric telescopic rod 409 is matched with the sum of the lengths of the rotating frame 104 and the sliding frame 105.

[0053] Those skilled in the art will understand that the output of the fifth drive motor 404 drives the drive gear 403 to rotate, causing the connecting gear 402 and the second rotating plate 401 to rotate as a whole, thereby causing all structures located on the left side of the second rotating plate 401 to rotate synchronously; and the output of the second stepper motor 405 drives the third lead screw 406 to rotate, causing the lifting block 408 to move up and down along the outer wall of the third guide rod 407, thereby enabling all structures connected to the lifting block 408 to move up and down; and the multi-stage electric telescopic rod 409 can be said to consist of two parts, one part being the mounting rod and the other part being several sets of sliding rods. The right end of the mounting rod is fixed to the left side wall of the lifting block 408, and the several sets of sliding rods slide relative to each other, and can be completely housed inside the mounting rod or can be completely extended outside the mounting rod. In other words, the multi-stage electric telescopic rod 409 can drive the moving plate 410 to move back and forth.

[0054] Please refer to Figure 8 and Figure 9 As shown, a first electric lifting rod 411 is rotatably connected inside the movable plate 410. The output end of the first electric lifting rod 411 is fixedly connected to the first lifting component 415. A blower 416 is installed at the bottom of the first lifting component 415. A first driven wheel 414 is connected to the outer surface of the first electric lifting rod 411. A sixth drive motor 412 is provided at the top of the movable plate 410. The output end of the sixth drive motor 412 is connected to the first drive wheel 413. The first drive wheel 413 is connected to the first driven wheel 414 via a first belt.

A connector 420 is rotatably connected inside the mounting frame 418. An eighth drive motor 419 for driving the connection 420 to rotate is installed on the outside of 418, and a ninth drive motor 421 is provided at the outer end of the connection 420. A fixed frame 422 is installed at the output end of the ninth drive motor 421. A first threaded rod 423 is rotatably connected inside the fixed frame 422. The threads at both ends of the first threaded rod 423 have opposite directions. A first fixed rod 424 is also installed inside the fixed frame 422. Two sets of third clamping members 426 are slidably connected to the first fixed rod 424. The two sets of third clamping members 426 are respectively threaded to the two ends of the outer surface of the first threaded rod 423. A first servo motor 425 for driving the first threaded rod 423 to rotate is provided on the outside of the fixed frame 422. The two sets of third clamping members 426 are used to clamp milling cutters or grinding heads.

[0055] Those skilled in the art will understand that the first lifting member 415 is driven to move up and down by the output end of the first electric lifting rod 411, thereby driving the blower 416 to move up and down and the milling cutter or grinding head held by the two sets of third clamping members 426 to move up and down.

[0056] The output of the sixth drive motor 412 drives the first drive wheel 413 to rotate. Under the drive of the first belt, the first driven wheel 414 and the first electric lifting rod 411 rotate synchronously, causing the milling cutters or grinding heads held by the two sets of third clamping members 426 to rotate around the first electric lifting rod 411 as the "center". The output of the seventh drive motor 417 drives the mounting frame 418 to rotate, causing the milling cutters or grinding heads held by the two sets of third clamping members 426 to rotate in the vertical plane. The output of the eighth drive motor 419 drives the connecting member 420 to rotate, causing the milling cutters or grinding heads held by the two sets of third clamping members 426 to rotate in another vertical plane. These two vertical planes are perpendicular. In summary, the milling cutters or grinding heads in the clamping state can be adjusted at a good angle, which is suitable for milling and grinding during the processing of injection molding machine screws.

[0057] The first servo motor 425 drives the first threaded rod 423 to rotate, causing the two sets of third clamping members 426 to move closer or further apart. When they move closer, they can securely clamp the milling cutter or grinding head, and when they move further apart, they can release the clamping of the milling cutter or grinding head.

[0058] Please refer to Figure 7 and Figure 10 As shown, a second electric lifting rod 427 is fixedly connected to the mounting rod of the multi-stage electric telescopic rod 409.

A third stepper motor 436 that drives the fourth lead screw 434 to rotate is installed on the outside of the connecting frame 433.

[0059] Please refer to Figure 10 and Figure 11As shown, a second threaded rod 438 is rotatably connected inside the movable frame 437. Both ends of the second threaded rod 438 are threadedly connected to fourth clamping members 441. Both sets of fourth clamping members 441 are slidably connected to a second fixed rod 439. The second fixed rod 439 is welded inside the movable frame 437. A second servo motor 440 is provided on the outer side of the movable frame 437 to drive the second threaded rod 438 to rotate. The two sets of fourth clamping members 441 are used to clamp the drill bit. A rotating member 443 is rotatably connected inside the movable disk 442. Inner and outer circumferential surfaces of the rotating member 443 are respectively equipped with inner... The movable disk 442 is rotatably connected to a set of first gears 444 and several sets of second gears 445. A transmission motor 446 that drives the first gears 444 to rotate is fixedly installed on the inner wall of the movable disk 442. Several sets of toothed plates 447 are also slidably connected inside the movable disk 442. The several sets of toothed plates 447 mesh with several sets of second gears 445 respectively. The first gears 444 mesh with the external teeth, and the second gears 445 mesh with the internal teeth. A cross plate 448 is welded to the outer end of the toothed plate 447, and a sliding plate 449 is installed on the outer end of the cross plate 448.

[0060] Those skilled in the art will understand that the output end of the second electric lifting rod 427 drives the second lifting component 428 to move up and down, thereby driving the connecting frame 433 to move up and down, which in turn drives the drill head held by the two sets of fourth clamping components 441 to move up and down, as well as all the abutting horizontal plates 448 and abutting inclined plates 449 to move up and down as a whole.

[0061] The output of the tenth drive motor 430 drives the active gear 431 to rotate, which causes the passive gear 432 and the second electric push rod 429 to rotate synchronously. This causes the connecting frame 433, the drill head, and the abutting horizontal plate 448 and the abutting inclined plate 449 to rotate around the second electric push rod 429 as the "center".

[0062] The output of the third stepper motor 436 drives the fourth lead screw 434 to rotate, so that the moving frame 437 and the moving disk 442 move back and forth synchronously along the fourth guide rod 435, realizing that both the moving frame 437 and the moving disk 442 can move to the middle of the connecting frame 433, and the middle of the connecting frame 433 and the center of the second electric push rod 429 are on the same straight line.

[0063] The output of the second servo motor 440 drives the second threaded rod 438 to rotate, causing the two sets of fourth clamping members 441 to move closer or further apart. When they move closer, the drill head is firmly clamped, and when they move further apart, the drill head is released from clamping.

[0064] The first gear 444 is driven to rotate by the output end of the transmission motor 446. The first gear 444 meshes with the external teeth, causing the external teeth, rotating part 443 and internal teeth to rotate as a whole. This causes all the second gears 445 to rotate synchronously, so that all the toothed plates 447 move synchronously toward the center of the moving disk 442 or away from the center of the moving disk 442. This causes the abutting plate 448 and the abutting inclined plate 449 to move synchronously toward the center of the moving disk 442 or away from the center of the moving disk 442.

The fifth lead screw 502 is rotatably connected between the two sets of second fixing blocks 501. The fifth guide rod 503 is fixedly installed between the two sets of second fixing blocks 501. The storage component 505 is threadedly connected to the fifth lead screw 502 and slidably connected to the fifth guide rod 503. A fourth stepper motor 504 for driving the fifth lead screw 502 to rotate is provided on the outer side of one set of second fixing blocks 501. Several sets of milling cutters, grinding heads, and drilling heads are provided inside the storage component 505.

[0067] Those skilled in the art will understand that the output of the fourth stepper motor 504 drives the fifth lead screw 502 to rotate, causing the storage component 505 to reciprocate along the fifth guide rod 503, thereby driving the several sets of milling cutters, grinding heads and drilling heads stored thereon to reciprocate, and all of them can move sequentially to the middle of the fifth guide rod 503.

[0068] Example 7

[0069] Please refer to Figure 13As shown, the detection mechanism 6 includes a third fixing block 601. Two sets of the third fixing blocks 601 are welded to the rear side of the top of the machine body 1. A sixth lead screw 602 is rotatably connected between the two sets of third fixing blocks 601. A moving part 605 is threadedly connected to the sixth lead screw 602. The moving part 605 is slidably connected to a sixth guide rod 603. The sixth guide rod 603 is welded between the two sets of third fixing blocks 601. A fifth stepper motor 604 that drives the sixth lead screw 602 to rotate is installed on the outer side of one set of third fixing blocks 601. A flip motor 606 is provided on the top of the outer side of the moving part 605. The output end of the flip motor 606 is fixedly connected to the flip plate 607. Furthermore, a third electric push rod 608 is rotatably connected inside the flip plate 607. A motor 610 is installed on the outer wall of the flip plate 607. A second drive wheel 611 is fixedly installed at the output end of the motor 610. A second driven wheel 609 is connected to the third electric push rod 608.

A fifth clamping member 614 is installed at both output ends of the second double-headed cylinder 613. The two sets of fifth clamping members 614 are used to clamp the thread gauge 615.

[0070] Those skilled in the art will understand that the rotating plate 607 can be rotated by the output end of the rotating motor 606, so that the rotating plate 607 can be in a vertical or horizontal state; the sixth lead screw 602 can be rotated by the output end of the fifth stepper motor 604, so that the moving part 605 can move horizontally back and forth, thereby realizing the reciprocating motion of the thread gauge 615; and by controlling the extension or retraction of the two output ends of the second double-headed cylinder 613, the two sets of fifth clamping parts 614 can be moved closer or further apart, thereby realizing the rapid installation and removal of the thread gauge 615.

[0071] In real-world injection molding machines, there are two types of screws used for molding: single-screw diamond screws and auxiliary-screw diamond screws, such as... Figure 14 As shown, the tail of the single-screw diamond screw is cylindrical, while the tail of the auxiliary-screw diamond screw is conical. To clearly describe the working principle of this invention, we use... Figure 1 The azimuth angle will be explained in detail below:

[0072] S1. The output of the second drive motor 106 drives the shielding frame 107 to rotate upward, opening the opening at the right end of the sliding frame 105. The robotic arm 101 clamps the external workpiece and transfers it into the interior of the rotating frame 104. The output of the third drive motor 306 drives one set of driven gears 304 to rotate, so that all the second clamping parts 307 move synchronously toward the center of the first rotating plate 301 to clamp the left end of the workpiece. This makes the device well applicable to the processing of workpieces with different outer diameters.

[0073] S2. The output end of the first stepper motor 205 drives the first lead screw 204 to rotate, causing the movable block 206 to move to the right, thereby driving the sliding frame 105 to move to the right along the outer wall of the rotating frame 104, so that the workpiece is located inside the rotating frame 104 and the sliding frame 105. The output end of the second drive motor 106 rotates in the opposite direction, and the blocking frame 107 covers the opening at the right end of the sliding frame 105, so that the device can be well applied to the processing of workpieces of different lengths.

[0074] S3. When processing a single-screw diamond screw with a "cylindrical" tail, the output end of the first electric push rod 108 is extended by controlling it, so that the two sets of first clamping parts 110 move to the tail of the workpiece. Then, the two output ends of the first double-headed cylinder 109 are retracted by controlling them, so that the two sets of first clamping parts 110 move closer to each other and clamp the outer wall of the tail of the workpiece.

[0075] The output end of the second electric lifting rod 427 drives the second lifting component 428 to move downward. Then, under the action of the output end of the third stepper motor 436, the moving frame 437 moves to the middle of the connecting frame 433, that is, the center of the drilling head and the center of the second electric push rod 429 are on the same straight line. With the cooperation of the output end of the second electric push rod 429 and the output end of the tenth drive motor 430, the drilling head moves to the left and rotates at the same time, thereby realizing the drilling of the right end of the tail of the workpiece.

[0076] Based on the outer diameter of the workpiece, the output end of the second stepper motor 405 is controlled to rotate, driving the third lead screw 406 to rotate. This causes the lifting block 408 to reciprocate up and down, moving the milling cutters held by the two sets of third clamping members 426 to the outer wall of the workpiece. Then, the output end of the second electric lifting rod 427 drives the second lifting member 428 to move downwards again, aligning the center of the second electric push rod 429 with the center of the drill hole at the right end of the workpiece's tail. Again, under the action of the output end of the third stepper motor 436, the moving disk 442 moves to the connecting frame 433. The center of the moving disk 442 and the center of the second electric push rod 429 are on the same straight line. The output end of the second electric push rod 429 extends, driving all the abutting horizontal plates 448 and abutting inclined plates 449 to extend into the drill hole. The output end of the transmission motor 446 drives the first gear 444 to rotate, so that the abutting horizontal plates 448 and abutting inclined plates 449 move synchronously away from the center of the moving disk 442. The outer wall of the abutting horizontal plate 448 abuts against the inner wall of the drill hole, thereby clamping the right end of the tail of the workpiece.

[0077] Then, the multi-stage electric telescopic rod 409 can drive the milling cutter to move left and right, and the angle of the milling cutter can be well adjusted. The output end of the fourth drive motor 308 drives the first rotating plate 301 to rotate, thereby driving the workpiece in the clamping state to rotate, thus realizing the engraving and milling of threads on the outer wall of the tail of the workpiece. Since both ends of the workpiece are in the clamping state, the engraving and milling is more precise, meeting the needs of the workers. It is worth noting that during processing, the output end of the fifth drive motor 404 also needs to drive the drive gear 403 to rotate, so that the second rotating plate 401 rotates, which is also a way to drive the milling cutter to rotate. Since the second electric push rod 429 rotates inside the second lifting member 428, there is no motion interference problem.

[0078] S4. When machining the conical auxiliary screw, the two sets of first clamping parts 110 are brought close to each other to clamp the outer wall of the tail of the workpiece. First, the conical shape is machined at the tail of the workpiece by milling cutter. Then, the above steps are repeated. The moving disk 442 is moved to the middle of the connecting frame 433. Then, the output end of the transmission motor 446 drives the first gear 444 to rotate, so that the abutting horizontal plate 448 and the abutting inclined plate 449 move synchronously towards the center of the moving disk 442. The outer wall of the abutting inclined plate 449 abuts against the conical outer wall, thereby clamping the right end of the tail of the workpiece. Then, the thread is milled by milling cutter. Since both ends of the workpiece are also clamped, the milling is more accurate and further meets the needs of the workers.

[0079] S5. Whether it is the processing of the tail end of a single-screw diamond screw or the processing of the tail end of a secondary-screw diamond screw, the generated "waste chips" fall inside the rotating frame 104 and the sliding frame 105. The output end of the first stepper motor 205 drives the sliding frame 105 to move to the right along the outer wall of the rotating frame 104, so that the right end of the sliding frame 105 moves to the top of the waste collection box 111. The output end of the second drive motor 106 drives the shielding frame 107 to rotate upward, opening the opening at the right end of the sliding frame 105. Then, the output end of the first drive motor 103 drives the rotating frame 104 to rotate, so that the opening at the right end of the sliding frame 105 tilts downward, thereby realizing the "waste chips" being poured into the waste collection box 111 for collection, maintaining the cleanliness of the environment, and also meeting the needs of the staff.

[0080] S6. During processing, if the milling cutter, grinding head, or drilling head is damaged, the output end of the second drive motor 106 drives the shielding frame 107 to rotate upward by 90 degrees, so that the second rotating plate 401 is in a horizontal state. The output end of the fourth stepper motor 504 drives the fifth lead screw 502 to rotate, so that the required milling cutter, grinding head, and drilling head can move sequentially to the middle of the fifth guide rod 503. Under the action of the output end of the second stepper motor 405, the two sets of third clamping members 426 or the two sets of fourth clamping members 441 can move to directly above the middle of the fifth guide rod 503. The output end of the multi-stage electric telescopic rod 409 drives the two sets of third clamping members 426 to move downward, and then the two sets of third clamping members 426 can clamp the milling cutter or grinding head. Similarly, the output end of the second electric push rod 429 drives the two sets of fourth clamping members 441 to move downward, and then the two sets of fourth clamping members 441 can clamp the drilling head. It is convenient and quick.

[0081] S7. After the single-screw or auxiliary-screw screw is processed, the threads can be inspected. The output of the flipping motor 606 drives the flipping plate 607 to rotate, so that the flipping plate 607 is in a horizontal state, and the center of the thread gauge 615 is on the same straight line as the center of the single-screw or auxiliary-screw screw. The output of the fifth stepper motor 604 drives the sixth lead screw 602 to rotate, so that the moving part 605 moves horizontally to the left, realizing that the thread gauge 615 moves to the right end position of the single-screw or auxiliary-screw screw. Then, with the cooperation of the motor 610 and the third electric push rod 608, the thread gauge 615 moves to the left and rotates at the same time to observe whether the thread gauge 615 can be twisted on the single-screw or auxiliary-screw screw. According to the different thread requirements of different processing, the thread gauge 615 can be adapted and replaced. Thus, the present invention realizes automated mass production of injection molding machine screws without manual operation, which has substantial improvement and is conducive to widespread use.
