Description

Technical Field

[0001] This invention relates to the field of screw processing technology, specifically to a milling and turning composite machining device for injection molding screw production. Background Technology

[0002] The injection screw is an important component of the injection molding machine. Its function is to transport, compact, melt, mix and pressurize plastic.

[0003] Currently, when processing injection molding screws, to avoid the splashing of debris generated during processing, the process is usually carried out inside a box. However, since the length of the workpiece material being processed varies, operators need to change processing devices of different lengths. This method leads to higher production costs for enterprises and also reduces the applicability of the equipment. Another method is to send one end of the workpiece material into the box when the workpiece material is long, exposing the other end, and sealing it. After processing that end, if continuous threads need to be processed on the workpiece, the workpiece material is turned around and sealed again. This method is more troublesome, time-consuming, labor-intensive, and has a low degree of automation. Summary of the Invention

[0040] 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.

[0041] Example 1

[0042] Please refer to Figures 1-15 As shown, a milling and turning composite machining device for injection molding screw production includes a body 1. The body 1 has two sets of support plates 102 fixedly installed on its top left side. A machining box 103 is rotatably connected between the two sets of support plates 102. A machining mechanism 3 is installed at the top of the machining box 103. A first drive motor 104 for driving the machining box 103 to rotate is installed on the front side of one set of machining boxes 103. A robotic arm 101 for feeding is installed on the top right side of the body 1. A feeding mechanism 2, a first auxiliary mechanism 4, and a second auxiliary mechanism 5 are installed between the robotic arm 101 and the machining box 103. The first auxiliary mechanism 4 and the second auxiliary mechanism 5 are located at the back and front of the feeding mechanism 2, respectively.

[0043] Please refer to Figure 2 and Figure 9As shown, the bottom of the processing box 103 is provided with an inclined surface. The bottom left side of the processing box 103 is provided with a discharge port. A cover plate 105 is installed on the outside of the discharge port. The top center of the cover plate 105 is fixedly connected to the output end of the cylinder 106. The cylinder 106 is located on the left side of the processing box 103, and a first sealing groove 107 is provided on the right side of the processing box 103.

[0044] Example 2

[0045] Please refer to Figure 4 As shown, the feeding mechanism 2 includes two sets of first fixed blocks 201 welded to the top of the machine body 1. A first lead screw 202 is rotatably connected between the two sets of first fixed blocks 201. A movable block 205 is threaded onto the first lead screw 202. The movable block 205 is slidably connected to the first guide rod 203. The two ends of the first guide rod 203 are respectively fixedly connected to the inner walls of the two sets of first fixed blocks 201. A first stepper motor 204 for driving the first lead screw 202 to rotate is provided on the outer wall of one set of first fixed blocks 201. A second drive motor 206 is installed on the top of the movable block 205. A connecting frame 207 is fixedly installed on the output end of the second drive motor 206.

[0046] Please refer to Figure 5 As shown, a first threaded rod 208 is rotatably connected inside the connecting frame 207. The threads at both ends of the first threaded rod 208 have opposite directions of rotation. Both ends of the outer surface of the first threaded rod 208 are threadedly connected to clamping members 211. A first fixing rod 209 is also welded inside the connecting frame 207. The clamping members 211 and the first fixing rod 209 are slidably connected. The outer end of the first threaded rod 208 is fixedly connected to the output end of the first servo motor 210. The first servo motor 210 is fixedly installed on the outside of the connecting frame 207.

[0047] Those skilled in the art will understand that the output of the first stepper motor 204 drives the first lead screw 202 to rotate, causing the movable block 205 to move horizontally back and forth along the surface of the first guide rod 203, thereby driving the two sets of clamping members 211 to move horizontally back and forth; the output of the first servo motor 210 drives the first threaded rod 208 to rotate, causing the two sets of clamping members 211 to move closer or further away from each other. When the two sets of clamping members 211 are close together, the workpiece material is clamped, and when the two sets of clamping members 211 are far apart, the clamping of the workpiece material is released.

[0048] Example 3

[0049] Please refer to Figure 4As shown, the machining mechanism 3 includes a second lead screw 301, a second guide rod 302, and a movable part 304. The second lead screw 301 is rotatably connected to the top of the inside of the machining box 103. The second guide rod 302 is fixedly installed at the top of the inside of the machining box 103. The movable part 304 is threadedly connected to the outer surface of the second lead screw 301 and slidably connected to the outer surface of the second guide rod 302. A second stepper motor 303 is installed on the top left side of the machining box 103. The output end of the second stepper motor 303 extends into the machining box 103 and is fixedly connected to the second lead screw 301. The inner part of component 304 is rotatably connected to a first rotating gear ring 305. A first electric push rod 308 is mounted on the outer side of the first rotating gear ring 305. The output end of the first electric push rod 308 is connected to a mounting base. A milling cutter 309 is rotatably connected inside the mounting base. A third drive motor 306 is provided on the outer side of the movable component 304. A first drive gear 307 that meshes with the first rotating gear ring 305 is fixedly mounted on the output end of the third drive motor 306. A second electric push rod 310 is also provided on the outer side of the movable component 304. The output end of the second electric push rod 310 is fixedly connected to a cutting tool 311.

[0050] Those skilled in the art will understand that by driving the second lead screw 301 to rotate through the output end of the second stepper motor 303, the moving part 304 reciprocates horizontally, thereby driving the milling cutter 309 and the turning tool 311 to reciprocate horizontally. According to common sense in machining, turning is used to machine rotating workpieces, while milling is used when the workpiece is fixed and the milling cutter rotates around the workpiece. Therefore, in this invention, the first drive gear 307 is driven to rotate through the output end of the third drive motor 306, causing the first rotating gear ring 305 to rotate, which in turn causes the milling cutter 309 to rotate around the center of the first rotating gear ring 305, thus providing the prerequisite for the "milling" operation.

[0051] Example 4

[0052] Please refer to Figure 4 As shown, the first auxiliary mechanism 4 includes a fixing member 401 welded to the rear top of the body 1. A third electric push rod 402 is provided on the outer side of the fixing member 401. The output end of the third electric push rod 402 is fixedly connected to the fixing frame 403. A second threaded rod 404 is rotatably connected inside the fixing frame 403. The threads at both ends of the second threaded rod 404 have opposite directions. A second fixing rod 405 is also fixedly connected inside the fixing frame 403. Two sets of locking blocks 407 are slidably connected on the second fixing rod 405. The two sets of locking blocks 407 are respectively threaded to both ends of the outer surface of the second threaded rod 404. A second servo motor 406 is provided on the outer side of the fixing frame 403. The outer end of the second threaded rod 404 is fixedly installed on the output end of the second servo motor 406.

[0053] As will be understood by those skilled in the art, initially, the two sets of locking blocks 407 are locked inside the slots 409 on the auxiliary ring 408. The output end of the second servo motor 406 drives the second threaded rod 404 to rotate, causing the two sets of locking blocks 407 to move closer or further apart. When the two sets of locking blocks 407 move further apart, they disengage from the slots 409, thereby releasing the auxiliary ring 408 from its clamping position. Furthermore, by controlling the extension or retraction of the output end of the third electric push rod 402, the two sets of locking blocks 407 are driven to move forward or to the right.

[0054] Please refer to Figure 11 and Figure 12 As shown, the first auxiliary mechanism 4 also includes an auxiliary ring 408. The outer side of the auxiliary ring 408 has a slot 409 that matches the locking block 407. A first sealing ring 410 that matches the first sealing groove 107 is installed on the side of the auxiliary ring 408 near the processing box 103. A second rotating gear ring 411 is rotatably connected inside the auxiliary ring 408. A fourth drive motor 412 is fixedly installed inside the auxiliary ring 408. The output end of the fourth drive motor 412 is fixedly connected to a second drive gear 413, and the second drive gear 413 meshes with the second rotating gear ring 411. Two sets of second fixing blocks 414 are welded to the outer side of the second rotating gear ring 411. A third threaded rod 415 is rotatably connected between the two sets of second fixing blocks 414. The threads at both ends of the third threaded rod 415 are in opposite directions. Clamping plates 418 are threaded to both ends of the outer surface of the third threaded rod 415. A third servo motor 417 for driving the third threaded rod 415 to rotate is provided on the outer wall of one set of second fixing blocks 414. The clamping plate 418 is slidably connected to the third fixing rod 416. The third fixing rod 416 is welded between the two sets of second fixing blocks 414.

[0055] Those skilled in the art will understand that when the left end of the workpiece material is inserted into the auxiliary ring 408, the output end of the third servo motor 417 drives the third threaded rod 415 to rotate, causing the two sets of clamping plates 418 to move closer to each other and clamp and fix the workpiece material. Meanwhile, the two sets of locking blocks 407 release the clamping of the auxiliary ring 408, thus enabling the auxiliary ring 408 to be installed on the outer surface of the workpiece material. Furthermore, the output end of the fourth drive motor 412 drives the second drive gear 413 to rotate, causing the second rotating gear ring 411 to rotate, which in turn causes the workpiece material to rotate, providing the prerequisite for the "car" operation of the machining.

[0056] Please refer to Figure 10As shown, a fourth threaded rod 419 is rotatably connected to the outer side of the auxiliary ring 408. Both ends of the outer surface of the fourth threaded rod 419 are threadedly connected to clamping blocks 422. The clamping blocks 422 are slidably connected to the fourth fixed rod 420. The fourth fixed rod 420 is fixedly installed on the outer side of the auxiliary ring 408. The threads at both ends of the fourth threaded rod 419 are in opposite directions. A fourth servo motor 421 is provided on the outer wall of the auxiliary ring 408. The outer end of the fourth threaded rod 419 is fixedly installed on the output end of the fourth servo motor 421. Both sets of clamping blocks 422 are detachably connected to sealing gaskets 423 on the side that is close to each other.

[0057] Those skilled in the art will understand that when the left end of the workpiece material is inserted into the auxiliary ring 408, a hole is provided on the right side of the auxiliary ring 408. In order to prevent debris generated during the processing from splashing out of the auxiliary ring 408, the present invention drives the fourth threaded rod 419 to rotate through the output end of the fourth servo motor 421, so that the two sets of clamping blocks 422 move closer to each other, and drive the two sets of sealing gaskets 423 to move closer to each other, thus wrapping the surface of the workpiece material. However, the function here is not clamping, and it will not affect the rotation of the workpiece material during the processing. Moreover, the sealing gaskets 423 are removable, and the appropriate sealing gaskets 423 can be selected according to the workpiece material with different outer diameters, which improves the practicality of the device.

[0058] Example 5

[0059] Please refer to Figure 13 As shown, the second auxiliary mechanism 5 includes two sets of third fixed blocks 501 fixedly connected to the top of the machine body 1. A third lead screw 502 is rotatably connected between the two sets of third fixed blocks 501. A movable plate 505 is threadedly connected to the third lead screw 502. The movable plate 505 is slidably connected to the third guide rod 503. The two ends of the third guide rod 503 are fixedly connected to the inner walls of the two sets of third fixed blocks 501 respectively. The outer end of the third lead screw 502 is fixedly connected to the output end of the third stepper motor 504. The third stepper motor 504 is set on the outer wall of one of the sets of third fixed blocks 501. A fourth electric push rod 506 is set on the outer side of the movable plate 505. A movable plate 507 is fixedly installed on the output end of the fourth electric push rod 506.

[0060] Please refer to Figure 14 and Figure 15As shown, a third rotating gear ring 508 is rotatably connected inside the moving plate 507. A fifth drive motor 509 is provided on the outer side of the moving plate 507. The output end of the fifth drive motor 509 is fixedly connected to a third drive gear 510 that meshes with the third rotating gear ring 508. A fifth threaded rod 511 is rotatably connected to the outer side of the third rotating gear ring 508. A fifth fixing rod 512 is also fixedly connected to the outer side of the third rotating gear ring 508. Two sets of clamping bars 514 are slidably connected to the fifth fixing rod 512. The two sets of clamping bars 514 are respectively threaded to both ends of the outer surface of the fifth threaded rod 511, and the threads at both ends of the fifth threaded rod 511 are in opposite directions. The two sets of clamping bars 514 are used to clamp the auxiliary thread gauge 515. A second sealing ring 516 that matches the first sealing groove 107 is also installed on the side of the auxiliary thread gauge 515 near the processing box 103. A fifth servo motor 513 that drives the fifth threaded rod 511 to rotate is provided on the outer side of the third rotating gear ring 508.

[0061] Those skilled in the art will understand that the output of the third stepper motor 504 drives the third lead screw 502 to rotate, causing the movable plate 505 to move horizontally back and forth along the surface of the third guide rod 503, thereby causing the auxiliary thread gauge 515 to move horizontally back and forth; the output of the fifth servo motor 513 drives the fifth thread rod 511 to rotate, causing the two sets of clamping bars 514 to move closer or further apart. When they move closer, the auxiliary thread gauge 515 is quickly clamped and installed, and when they move further apart, the installation of the auxiliary thread gauge 515 is released; and the output of the fifth drive motor 509 drives the third drive gear 510 to rotate, causing the third rotating gear ring 508 to rotate, thereby causing the auxiliary thread gauge 515, which is in the clamping state, to rotate.

[0062] 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 16 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 explanation is as follows:

[0063] (a) Machining of auxiliary screw:

[0064] When machining the auxiliary screw with a tapered tail, a turning operation is required:

[0065] S1. The robotic arm 101 clamps and transfers the workpiece material to be processed from the outside, keeping the workpiece material horizontal and between the two sets of clamping parts 211. Through the extension of the output end of the third electric push rod 402, the two sets of clamping blocks 407 and auxiliary ring 408 move forward, so that the center of the auxiliary ring 408 is concentric with the center of the workpiece material. The robotic arm 101 pushes the workpiece material to the left, so that the auxiliary ring 408 is located in the middle of the workpiece material.

[0066] S2. The output of the third servo motor 417 drives the third threaded rod 415 to rotate, causing the two sets of clamping plates 418 to move closer together. The workpiece material is installed on the second rotating gear ring 411. The output of the second servo motor 406 drives the second threaded rod 404 to rotate, causing the two sets of clamping blocks 407 to move away from each other and disengage from the clamping slots 409. The auxiliary ring 408 is released from clamping, and the auxiliary ring 408 is installed in the middle of the workpiece material. The output of the third electric push rod 402 is reset. Then, the output of the fourth servo motor 421 drives the fourth threaded rod 419 to rotate, causing the two sets of clamping blocks 422 to move closer together. This causes the two sets of sealing gaskets 423 to move closer together, wrapping the surface of the workpiece material. However, the function here is not clamping and will not affect the rotation of the workpiece material during the "car" operation.

[0067] S3. The output end of the first stepper motor 204 drives the first lead screw 202 to rotate, causing the movable block 205 and the two sets of clamping parts 211 to move to the left as a whole. The two sets of clamping parts 211 move to the position of the auxiliary ring 408 and are located on the front and rear sides of the auxiliary ring 408. The output end of the first servo motor 210 drives the first threaded rod 208 to rotate, causing the two sets of clamping parts 211 to move closer to each other, thereby clamping the auxiliary ring 408. The robotic arm 101 releases the clamping of the workpiece material.

[0068] S4. Continue to drive the movable block 205 and the two sets of clamping parts 211 to move to the left through the output end of the first stepper motor 204, so that the auxiliary ring 408 and the workpiece material move to the left. The first sealing ring 410 on the auxiliary ring 408 is stuck inside the first sealing groove 107. Then, drive the second drive gear 413 to rotate through the output end of the fourth drive motor 412, so that the second rotating gear ring 411 rotates, causing the workpiece material to rotate. At the same time, control the extension of the output end of the second electric push rod 310 to drive the cutting tool 311 to approach the left end of the workpiece material, thereby realizing the machining of a "cone" at the left end of the workpiece material.

[0069] When creating threads on the outer surface of the auxiliary screw, a milling operation is required:

[0070] S5. The output end of the fourth drive motor 412 no longer drives the second rotating gear ring 411 to rotate, so that the workpiece material is in a clamped and fixed state. With the cooperation of the rotating milling cutter 309 and the output end of the second stepper motor 303, the thread is opened on the outer surface of the auxiliary screw.

[0071] S6. Since the other half of the workpiece material is outside the processing box 103, if it is necessary to completely open the thread on the other half, the output end of the first stepper motor 204 drives the auxiliary ring 408 and the workpiece material as a whole to move to the right until reset. The robotic arm 101 clamps the right end of the workpiece material, and the two sets of clamping blocks 407 re-clamp the auxiliary ring 408 and reach the reset state. The output end of the fourth electric push rod 506 extends and drives the moving plate 507 to move to the rear. The center of the auxiliary thread gauge 515 is concentric with the center of the workpiece material. Under the action of the output end of the fifth drive motor 509, the auxiliary thread gauge 515 in the clamping state is driven to rotate. At the same time, the output end of the third stepper motor 504 drives the third lead screw 502 to rotate, so that the auxiliary thread gauge 515 moves to the right, thereby realizing the threaded connection between the auxiliary thread gauge 515 and the thread opened on the workpiece material. The auxiliary thread gauge 515 is located in the middle of the workpiece material.

[0072] S7. The output of the first servo motor 210 drives the first threaded rod 208 to rotate, causing the two sets of clamping members 211 to move closer to each other, thereby clamping the outer wall of the third rotating gear ring 508. The output of the first stepper motor 204 drives the movable block 205 and the two sets of clamping members 211 to move to the left as a whole, causing the third rotating gear ring 508, the auxiliary thread gauge 515 and the workpiece material to move to the left as a whole. The second sealing ring 516 on the auxiliary thread gauge 515 is also stuck inside the first sealing groove 107. The purpose of this is that, on the one hand, the debris generated during the subsequent milling operation cannot pass through the auxiliary thread gauge 515. If the auxiliary thread gauge 515 is not used, since the workpiece material has already been threaded, the two sets of sealing gaskets 423 cannot tightly wrap the surface of the workpiece material, and the generated debris can easily pass through the threads of the workpiece material. On the other hand, it can realize the creation of complete and continuous threads on the workpiece material, which meets the needs of the workers.

[0073] (II) Machining of single-screw diamond screws:

[0074] Similar to the machining steps of the auxiliary screw, the "turning" operation is reduced, and only the "milling" operation is required.

[0075] Furthermore, it is worth mentioning that, regardless of whether it is single-screw or auxiliary-screw machining, the generated debris will only fall inside the machining box 103. With the cooperation of the inclined surface at the bottom of the machining box 103, the output end of the cylinder 106 and the output end of the first drive motor 104, the debris can be quickly slid into the collection box at the bottom, which is convenient, fast and fully automated.
