Technical Field

[0001] This invention relates to the field of hardware processing technology, specifically a precision oscillating sawing device. Background Technology

[0002] In the large-scale batch processing of precision hardware parts, a sawing device is needed to precisely cut long materials into short finished products that meet specifications. Considering that hardware production generally adopts a large-batch mode, during the processing, the hardware parts that have been securely clamped need to be transferred to the processing station in sequence; then, the sawing device moves to the location of the hardware part to perform the sawing operation; after the sawing operation is completed, the sawing device needs to leave the processing station to make room for the subsequent hardware parts to be transferred to the processing station in sequence. However, the existing mechanisms used to adjust the position of the sawing device generally have shortcomings such as inconvenient operation and insufficient structural design; in addition, since the sawing device will be subjected to large reverse torque and vibration during the sawing process, if the structural strength is insufficient, it will affect the stability of the operation process. Based on this, we propose a precision oscillating sawing device. Summary of the Invention

The inner surface of the fine-tuning large gear is threadedly connected to the outer surface of the first outer shaft. The fine-tuning large gear is meshed with a fine-tuning small gear. The axle corresponding to the fine-tuning small gear is rotatably connected to the main shaft fixing seat. The fine-tuning large gear is provided with arc-shaped through grooves that correspond one-to-one with the fastening bolts.

[0006] Further options include: The upper clamping mechanism is used to clamp the upper end of the workpiece transferred to the sawing mechanism and lift the workpiece after it has been sawn off. A high-pressure oil nozzle, which is used to align with the workpiece after it has been sawn off; The receiving mechanism is used to receive the workpiece sent by the high-pressure oil nozzle after the upper clamping mechanism releases the workpiece that has been sawn off.

[0007] A further embodiment includes a drive motor for rotating a shaft. A cam is mounted on the end of the shaft away from the drive motor. At least one side of the cam has an annular pressing section. The height of the pressing section gradually increases and then gradually decreases. The pressing section is used to press the lower drive wheel, causing the lower drive wheel to drive the lower drive block downward and compress the first spring. The lower drive block is used to abut against the end of the lever away from the pull rod. The sawing mechanism hooks one end of the tension spring through a tension spring hook, and the other end of the tension spring is connected to a tension spring adjusting block.

[0008] A further embodiment includes a long lever, a third spring, and an upper drive block; both the upper and lower surfaces of the cam are provided with annular extrusion portions, with the extrusion portion away from the lower drive wheel acting on the upper drive wheel; the upper drive block is used to abut against one end of the long lever; the middle part of the long lever is rotatably connected to the first support column, and the other end of the long lever cooperates with the upper clamping mechanism; when the upper drive wheel drives the upper drive block to move upward, the upper clamping mechanism simultaneously compresses the third spring.

[0009] A further embodiment is that the upper clamping mechanism includes a clamping head, and a strip groove is formed on the circumferential surface of one end of the clamping head that is close to the workpiece. The clamping head is engaged with the clamping head mounting base, and the outer surface of the clamping head is wedge-shapedly fitted with the bottom end of the second central shaft. The second central shaft moves up and down under the action of the moving mechanism.

[0010] A further embodiment is that the upper clamping mechanism includes a second outer shaft, which is used to drive the drive rod to move synchronously; the outer wall of the guide sleeve is rotatably connected to one end of the receiving head, the receiving head is equipped with a receiving tube and has a limit groove, and one end of the drive rod is slidably engaged with the limit groove; so that when the upper clamping mechanism lifts the sawn workpiece, the receiving mechanism moves closer to the workpiece synchronously.

[0012] A further embodiment is that the moving mechanism includes a first cylinder, a second lever, a support base, and a second spring. The middle part of the second lever is rotatably connected to the support base, and the end of the second lever away from the first cylinder is used to abut against a threaded sleeve. The threaded sleeve is connected to one end of a second central shaft, and the outer surface of the threaded sleeve is provided with an annular portion that cooperates with the second lever. The output end of the first cylinder acts on one end of the second lever, so that the second lever lifts the threaded sleeve and simultaneously compresses the second spring.

[0013] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention facilitates the automatic switching of the saw blade between the first and second positions by setting a swing mechanism; when the saw blade is in the first position, the saw blade will not obstruct the transfer of the workpiece to be processed to the sawing mechanism; when the saw blade is switched to the second position, the saw blade can easily cut the workpiece to be processed; in addition, the swing mechanism structure of the present invention is not only ingeniously designed, but also compact in structure and will not occupy the external space of the lower disc; due to the use of lever and pull rod, the swing mechanism structure has high strength, and the pure mechanical structure design has the characteristics of high running stability; therefore, the present invention has the advantages of precision, stability and durability. (2) Through the mutual cooperation of the fine adjustment pinion, fine adjustment large gear, main shaft fixing seat, first outer shaft, copper sleeve, first central shaft, fastening bolt and arc through groove, the present invention can drive the fine adjustment large gear to rotate after the fine adjustment pinion is turned, thereby driving the first outer shaft to produce a small displacement in the height direction, and finally realize the precise fine adjustment of the sawing mechanism in the height direction, effectively eliminating the assembly error of the sawing mechanism and improving the sawing accuracy; (3) After the cam is driven to rotate by the drive motor, the upper drive wheel will be driven to move up and the lower drive wheel will move down simultaneously. This will automatically realize the simultaneous operation of the two actions of the upper clamping mechanism moving down to clamp the workpiece and the sawing mechanism moving close to the workpiece to saw the workpiece. This ensures that the upper clamping mechanism can clamp the workpiece at the same time during the sawing process. (4) The present invention clamps the upper end of the workpiece transferred to the sawing mechanism by the upper clamping mechanism, which can effectively prevent the finished workpiece after sawing from falling out of order, and provides a guarantee for the receiving mechanism to receive the finished workpiece smoothly. (5) After the clamping head releases the finished workpiece, the second cylinder is started simultaneously. The second cylinder can drive the ejector head to move downward. The ejector head plays the role of ejecting the workpiece out of the clamping head, which makes it easier for the workpiece to get out of the clamping head and prevents the workpiece from falling smoothly by its own weight due to being contaminated with metal cutting oil. (6) The present invention drives the guide seat to move upward synchronously through the second outer shaft, so that the drive rod slides upward along the limiting groove, thereby making the receiving mechanism approach the finished workpiece synchronously, which makes it easier for the receiving mechanism to receive the finished workpiece sent by the high pressure oil. (7) The structure of the present invention is ingeniously designed and has the advantages of high rigidity, good stability and high precision, and is suitable for mass production of precision small hardware parts; (8) The present invention is designed to be precise and compact, and can achieve high output and high output value.

[0016] To make the objectives, features, and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0018] Please see Figure 1 This invention provides a precision oscillating sawing device, including a base 1, a lower disc 2 mounted on the upper end of the base 1, and a middle disc 3 rotatably connected to the lower disc 2. Furthermore, the lower disc 2 is connected to a small disc 13 via a third guide rod 12, and the small disc 13 is fixed to the upper disc 4 by a positioning pin and several screws. The middle disc 3 can be driven to rotate by a servo motor (not shown in the figure). Since the servo motor can precisely control the rotation angle, it can also precisely control the rotation angle of the middle disc 3. It should be noted that, besides precisely controlling the rotation angle of the middle disc 3 via a servo motor, other methods in the prior art can also be used, and those skilled in the art can set them according to actual needs; all of these fall within the scope of protection in this field. A lower clamping mechanism is distributed in a ring array on the middle disc 3. The lower clamping mechanism is used to clamp the bottom end of the metal part to be processed. The lower clamping mechanism can be an existing clamping mechanism; this invention does not limit the specific structure of the lower clamping mechanism. The material of the metal part to be processed can be brass, stainless steel, steel, and aluminum, etc., but is not limited to these.

[0019] It should be noted that, in order to clearly demonstrate the specific structure of the present invention, Figure 1 The middle disk 3, small disk 13 and upper disk 4 in the figure all show a part of the structure, which does not mean that the middle disk 3, small disk 13 and upper disk 4 are fan-shaped structures.

[0020] Please see Figures 1-7A sawing mechanism 6 is provided on the lower disc 2, and the sawing mechanism 6 includes a main shaft fixing seat 605 mounted on the lower disc 2. A first outer shaft 604 is provided on the main shaft fixing seat 605, and a copper sleeve 603 is interference-fitted to the inner surface of the first outer shaft 604. A first central shaft 602 is rotatably fitted to the inner surface of the copper sleeve 603; a first inner shaft 601 is provided on the inner surface of the first central shaft 602, and the first central shaft 602 is rotatably connected to the first inner shaft 601 through a bearing. The first inner shaft 601 is driven to rotate by a power mechanism 5. A gearbox lower cover 616 is installed at the top of the first central shaft 602, and the gearbox lower cover 616 is fixedly connected to the gearbox upper cover 615 by a locating pin and bolts. A transmission mechanism is provided within the space enclosed by the lower gearbox cover 616 and the upper gearbox cover 615. The transmission mechanism includes a first helical gear 606, a second helical gear 607, and a third helical gear 608. The first helical gear 606 meshes with the third helical gear 608 via the second helical gear 607. The first helical gear 606 and the second helical gear 607 are respectively mounted on a first rotating spindle 609 and a second rotating spindle 610. Of course, the transmission mechanism can also be implemented in other ways as described in the prior art, and this application does not impose specific limitations. Furthermore, the top end of the first inner shaft 601 extends into the space enclosed by the lower gearbox cover 616 and the upper gearbox cover 615 to facilitate the mounting of the third helical gear 608 onto the first inner shaft 601. Additionally, a saw blade 611 is mounted on the upper end of the first rotating spindle 609 after it passes through the upper gearbox cover 615. Specifically, the saw blade 611 is an alloy saw blade, which is mounted on the rotating spindle 609 via an upper pressure ring 612 and a lower pad ring 613. The saw blade 611, upper pressure ring 612, and lower pad ring 613 are first inserted into the rotating spindle 609 and then locked in place by a locking cap. Therefore, after the power mechanism 5 drives the first inner shaft 601 to rotate, the high-speed rotational cutting function of the saw blade 611 is achieved through the cooperation of the transmission mechanism, enabling the saw blade 611 to cut the alloy workpiece to be processed.

[0021] Preferably, the top end of the first inner shaft 601 is rotatably connected to the gearbox cover 615 via a bearing. The outer surface of the second rotating spindle 610 is interference-fitted with the inner ring of the bearing. The outer ring of the bearing corresponding to the second rotating spindle 610 is interference-fitted with the inner ring of the second helical gear 607. The first rotating spindle 609 is rotatably connected to the gearbox cover 615 and the gearbox cover 616 via bearings. This effectively reduces the frictional resistance and vibration amplitude during the operation of the first inner shaft 601, improves the overall rigidity and operational stability of the device, ensures the accuracy and durability of the saw blade 611 during high-speed cutting, and guarantees the reliability of the equipment for long-term continuous operation.

[0022] Better, such as Figure 3 and Figure 7As shown, a saw blade guard 614 is provided on the upper surface of the gearbox cover 615. The saw blade guard 614 is located on the side of the saw blade 611 away from the workpiece to be processed. A guard cover plate is also provided on the upper end of the saw blade guard 614. The saw blade guard 614 and the guard cover plate cover the saw blade 611, which can play a protective role.

[0023] Preferably, such as Figure 2 As shown, the power mechanism 5 includes a motor 501, a drive wheel 502, a timing belt 503, and a driven wheel 504. The motor 501 is mounted on the outer surface of the base 1. The output end of the motor 501 is connected to the drive wheel 502. The drive wheel 502 drives the driven wheel 504 to rotate via the timing belt 503. The driven wheel 504 is connected to the bottom end of the first inner shaft 601 via a locking cap, thereby driving the first inner shaft 601 to rotate at high speed. It should be noted that, in addition to the motor 501 driving the first inner shaft 601 to rotate at high speed through the cooperation of the drive wheel 502 and the driven wheel 504, in practical applications, the motor 501 can also directly drive the first inner shaft 601 to rotate at high speed, or the motor 501 can drive the first inner shaft 601 to rotate at high speed through gear meshing. All of these are within the scope of protection of this application.

[0024] Please see Figures 8-10 To achieve fine-tuning of the saw blade 611 in the height direction, this invention provides a fine-tuning mechanism 8, which includes a large fine-tuning gear 802 and a small fine-tuning gear 801. The axle corresponding to the small fine-tuning gear 801 is rotatably connected to the main shaft fixing seat 605, while the large fine-tuning gear 802 is mounted on the main shaft fixing seat 605 by fastening bolts, and the large fine-tuning gear 802 has arc-shaped through grooves 8021 corresponding to the fastening bolts. In addition, the inner surface of the large fine-tuning gear 802 is threadedly connected to the outer surface of the first outer shaft 604, and the first outer shaft 604 is slidably engaged with the main shaft fixing seat 605; moreover, the top of the first outer shaft 604 and the copper sleeve 603 abuts against the stepped portion provided on the outer surface of the first central shaft 602. When there is an assembly error in the height direction of the saw blade 611, the fastening bolts of the fixed connection between the large fine-tuning gear 802 and the main shaft fixing seat 605 can be loosened slightly, so that the large fine-tuning gear 802 can rotate. At this time, the small fine-tuning gear 801 can be turned by using an Allen wrench in conjunction with the hexagonal hole on the bottom surface of the small fine-tuning gear 801, so as to drive the large fine-tuning gear 802 to rotate, thereby causing the first outer shaft 604 to move slightly in the height direction. Finally, the sawing mechanism 6 can be precisely fine-tuned in the height direction, which can eliminate the assembly error.

[0025] It should be noted that, as Figure 9As shown, the fine-tuning gear 802 has an arc-shaped through groove 8021 that corresponds to the fastening bolt. Therefore, during the rotation of the fine-tuning gear 802, the fine-tuning gear 802 will not interfere with the fastening bolt, so that the fastening bolt will not hinder the rotation of the fine-tuning gear 802, thereby enabling the saw blade 611 to be finely adjusted in the height direction.

[0026] For example, the number of fastening bolts can be set to 3, and the corresponding arc through groove 8021 has 3 grooves; it is understood that setting the number of fastening bolts to 3 is just an example, and the specific number of fastening bolts can be set according to the requirements.

[0027] Better, such as Figure 8 and Figure 10 As shown, the fine-tuning mechanism 8 also includes a large gear pressure ring 803 and a locking ring 804. The large gear pressure ring 803 is sleeved on the first central shaft 602, while the locking ring 804 is threaded onto the first central shaft 602. The large gear pressure ring 803 limits the fine-tuning large gear 802 under the action of the locking ring 804. In order not to affect the rotation of the fine-tuning large gear 802 during the fine-tuning process, the locking ring 804 needs to be turned downwards in advance so that the large gear pressure ring 803 no longer limits the fine-tuning large gear 802. It should be noted that the large gear pressure ring 803 has a groove 8031, making the large gear pressure ring 803 step-shaped, so that the first outer shaft 604 can move downwards in the height direction to the height corresponding to the depth of the groove 8031 ​​without affecting the large gear pressure ring 803 pressing against the fine-tuning large gear 802. After the assembly error is eliminated, the fine-tuning gear 802 is fixed to the main shaft mounting base 605 by tightening the bolts. At this time, the large gear pressure ring 803 is brought close to the fine-tuning gear 802 under the action of the locking ring 804. The large gear pressure ring 803 can prevent the fastening screws of the fine-tuning gear 802 from loosening due to long-term device vibration, which would cause the entire sawing mechanism 6 to move up and down. It is worth noting that the large gear pressure ring 803 is not completely pressed against the lower surface of the fine-tuning gear 802. By adjusting the gap, it can be ensured that the fine-tuning gear 802 will not interfere with the swing of the sawing mechanism 6, and the large gear pressure ring 803 can limit the fine-tuning gear 802, thereby preventing the entire sawing mechanism 6 from moving up and down.

[0028] Please see Figure 2 and Figure 6To enable the sawing mechanism 6 to swing so that the saw blade 611 neither obstructs the transfer of the workpiece to be processed to the sawing mechanism 6 nor fails to cut the conveyed workpiece, the present invention also includes a swinging mechanism 7. The swinging mechanism 7 includes a swing block 701, a pull rod 702, a first lever support 703, a second lever support 704, and a first lever 705. The swing block 701 is mounted on the swing shaft corresponding to the sawing mechanism 6, that is, the swing block 701 is mounted on the first central shaft 602; specifically, the swing block 701 is fixedly connected to the first central shaft 602 by a pin and screws. The swing block 701 is rotatably connected to one end of the pull rod 702 via a fisheye bearing, and the other end of the pull rod 702 is rotatably connected to the second lever support 704. The second lever support 704 is mounted on the end of the first lever 705, and the middle part of the first lever 705 is rotatably connected to the first lever support 703; the first lever support 703 is mounted on the lower disc 2. Furthermore, the other end of lever 705 reciprocates up and down under the action of drive mechanism 9; therefore, lever 705 will swing around lever support 703, thereby pulling pull rod 702 back and forth, and thus realizing the reciprocating swing of swing block 701. Since gearbox lower cover 616 is installed at the top of first central shaft 602, the sawing mechanism 6 can swing, so that saw blade 611 will not obstruct the transfer of workpiece to be processed to the sawing mechanism 6, and can saw the conveyed workpiece to be processed.

[0029] It should be noted that, since the outer surface of the first central shaft 602 rotates in conjunction with the copper sleeve 603, and the copper sleeve 603 itself has self-lubricating and wear-resistant properties, the entire sawing mechanism 6 will rotate smoothly, and the sawing rigidity and stability will be excellent.

[0030] It should be further explained that the swing mechanism 7 of the present invention is not only ingeniously designed, but also compact in structure, and will not occupy the external space of the lower disc 2. Due to the use of lever 705 and pull rod 702, the swing mechanism 7 has high structural strength, and the pure mechanical structure design has the characteristics of high operational stability, thus having the advantages of precision, stability and durability.

[0031] Please see Figure 1 and Figure 11The driving mechanism 9 includes a drive motor 901, the output end of which is connected to the input end of a reducer. The output end of the reducer is connected to one end of a rotating shaft 902. A cam 903 is mounted on the end of the rotating shaft 902 away from the reducer. Both the upper and lower surfaces of the cam 903 have annular pressing portions, the height of which gradually increases and then gradually decreases. The pressing portion corresponding to the lower curved surface of the cam 903 engages with a lower drive wheel 905, which is rotatably connected to a lower drive seat 904. A lower drive shaft 9061 is mounted on the lower drive base 904. A lower drive block 907 and a lower limit block 908 are mounted on the outer surface of the lower end of the lower drive shaft 9061 at intervals. The side of the lower drive block 907 near the lower limit block 908 is used to abut against the end of the lever 705 away from the pull rod 702. In addition, the side of the lower limit block 908 away from the lower drive block 907 is connected to one end of the first spring 910. The other end of the first spring 910 is connected to the first guide rod 911, and the first guide rod 911 is installed at the bottom of the inner cavity of the base 1. Therefore, when the drive motor 901 starts and drives the cam 903 to rotate, the height of the pressing part on the cam 903 gradually increases and then gradually decreases, so that the pressing part applies a pressing force to the lower drive wheel 905. Under the action of the downward pressing force, the lower drive wheel 905 will drive the lower drive block 907 to move downward and compress the first spring 910; and the downward moving lower drive block 907 will drive the lever 705 to swing downward; when the pressing part stops pressing, under the reset action of the first spring 910, the lower drive wheel 905 will move upward, so that the lower drive wheel 905 always abuts against the lower curved surface of the cam 903.

[0032] It should be noted that, in order to make the up-and-down movement of the lower drive shaft 9061 more stable, a lower cylinder sleeve 906 is provided on the outer surface of the lower drive shaft 9061. The lower cylinder sleeve 906 is fixedly installed in the inner cavity of the lower disc 2. A lower ball sleeve 9062 is provided on the inner wall of the lower cylinder sleeve 906. The lower drive shaft 9061 and the lower ball sleeve 9062 are in sliding engagement.

[0033] In this embodiment, the downward-moving lower drive block 907 causes lever 705 to swing downwards, which in turn drives the sawing mechanism 6 closer to the alloy part to be processed and completes the sawing operation. The upward-moving lower drive block 907 does not cause lever 705 to swing upwards. Therefore, the present invention provides a tension spring hook 710 on the gearbox cover 615. The tension spring hook 710 is used to hook one end of the tension spring 709, and the other end of the tension spring 709 hooks onto another tension spring hook mounted on tension spring adjusting block 708. Tension spring adjusting block 708 is mounted on tension spring adjusting block 707. Tension spring adjusting block 707 is mounted on a triangular plate 706, which is mounted on the lower disc 2 via a cylinder. When the sawing mechanism 6 approaches the alloy part to be processed and completes the sawing operation, it will stretch the tension spring 709. Then, when the lower drive block 907 is no longer pressed down by the cam 903, under the reset action of the tension spring 709, the sawing mechanism 6 moves away from the alloy part to be processed, so that the middle disc 3 can transfer the next alloy part to be processed to the processing station.

[0034] Please see Figure 1 and Figure 12 To facilitate the collection of sawn finished workpieces, this invention includes an upper clamping mechanism 10, a high-pressure oil nozzle, and a receiving mechanism 11. The upper clamping mechanism 10 clamps the upper end of the workpiece transferred to the sawing mechanism 6 and lifts the sawn finished workpiece to prevent it from falling off. Of course, the upper clamping mechanism 10 can also release the clamped workpiece. The high-pressure oil nozzle is aimed at the sawn workpiece and sprays high-pressure oil (not shown in the figure). When the upper clamping mechanism 10 releases the sawn workpiece, the receiving mechanism 11 receives the workpiece sent by the high-pressure oil and transports the finished workpiece out, thereby completing the collection of finished workpieces.

[0035] Specifically, such as Figure 11 and Figure 12As shown, the upper clamping mechanism 10 includes a long lever 1001, the middle of which is rotatably connected to a first support column 1002. The end of the first support column 1002 away from the long lever 1001 is mounted on a small disc 13. The pressing part of the cam 903 away from the lower drive wheel 905 engages with the upper drive wheel 913. The upper drive wheel 913 is rotatably connected to an upper drive seat 912. An upper drive shaft 9141 is mounted on the upper drive seat 912, and upper drive blocks 915 and upper limit blocks 916 are mounted on the upper drive shaft 9141 at intervals. The side of the upper drive block 915 near the upper limit block 916 abuts against one end of the long lever 1001; the other end of the long lever 1001 engages with the upper clamping mechanism 10. Therefore, when the upper drive wheel 913 drives the upper drive block 915 upward, it drives the upper clamping mechanism 10 downward to clamp the upper end of the workpiece transferred to the processing station. It is understandable that after the drive motor 901 drives the cam 903 to rotate, it will synchronously drive the upper drive wheel 913 to move upward and the lower drive wheel 905 to move downward. This will automatically realize the synchronous operation of the two actions of the upper clamping mechanism 10 moving downward to clamp the workpiece and the sawing mechanism 6 approaching the workpiece to saw it. This will ensure that the upper clamping mechanism 10 can clamp the workpiece at the same time when sawing it.

[0036] It should be noted that, in order to make the up-and-down movement of the upper drive shaft 9141 more stable, an upper cylinder liner 914 is provided on the outer surface of the upper drive shaft 9141, and the upper cylinder liner 914 is fixedly mounted on the small disc 13. An upper ball sleeve 9142 is provided on the inner wall of the upper cylinder liner 914, and the upper drive shaft 9141 slides in conjunction with the upper ball sleeve 9142.

[0037] Please see Figure 16 To achieve the upward reset of the upper clamping mechanism 10 after it has moved downward, the present invention provides a second sleeve 1019, which is mounted on the upper disc 4. A second movable block 1022 is slidably fitted at the upper end of the second sleeve 1019. The upper end of the second movable block 1022 extends through the top wall of the second sleeve 1019 and outwards, acting on the upper clamping mechanism 10. A second guide post 1020 is also provided inside the second sleeve 1019, which slidably fits with the middle of the second movable block 1022. A third spring 1021 is provided inside the second sleeve 1019, which abuts against the lower surface of the second movable block 1022. When the upper clamping mechanism 10 moves downward, the third spring 1021 is compressed synchronously, causing the upper drive block 915 to stop driving the long lever 1001. Under the reset action of the third spring 1021, the upper clamping mechanism 10 will reset upwards.

[0038] It should be noted that the present invention can either synchronously drive the upper clamping mechanism 10 to move downward and the sawing mechanism 6 to move closer to the workpiece to be processed by the driving mechanism 9, or it can use different driving methods to achieve the synchronous action of the upper clamping mechanism 10 moving downward and the sawing mechanism 6 moving closer to the workpiece to be processed; for example, the sawing mechanism 6 can be driven closer to the workpiece to be processed by the driving mechanism 9, while the upper clamping mechanism 10 can be directly driven downward by the electric telescopic rod; the technology in the field can be determined according to the actual situation, and the above methods are all within the protection scope of this application.

[0039] In some preferred embodiments, such as Figure 11 As shown, a set of guide wheels 909 are provided on the outer surfaces of both the lower drive seat 904 and the upper drive seat 912. The guide wheels 909 are in rolling cooperation with the third guide rod 12, so that the lower drive shaft 9061 and the upper drive shaft 9141 corresponding to the drive mechanism 9 will not tilt or deviate when moving up and down.

[0040] For further details, please refer to Figures 12-17 The upper clamping mechanism 10 includes a fixed plate 1005. A first cylinder mounting plate 1010 is fixedly connected to the upper surface of the fixed plate 1005 via a fixed post 1009. A first cylinder 1011 is mounted on the first cylinder mounting plate 1010. A support seat 1007 is also mounted on the fixed plate 1005. A lever 1008 is rotatably connected to the support seat 1007. The end of the lever 1008 away from the first cylinder 1011 is used to abut against a threaded sleeve 1023. The outer surface of the threaded sleeve 1023 is provided with an annular portion that mates with the lever 1008. When the output end of the first cylinder 1011 acts on one end of the second lever 1008, the second lever 1008 will lift the threaded sleeve 1023. In order to enable the second lever 1008 to drive the threaded sleeve 1023 to move downward, a first sleeve 1014 is provided on the fixing plate 1005 directly below the second lever 1008 near the first cylinder 1011. A first guide post 1015 and a first fixing block 1017 are installed in the first sleeve 1014. A first movable block 1018 is also slidably fitted in the first sleeve 1014, and the middle part of the first movable block 1018 is slidably fitted with the first guide post 1015. A second spring 1016 is also installed in the first sleeve 1014, and the two ends of the second spring 1016 are connected to the first fixing block 1017 and the first movable block 1018, respectively. When the output end of the first cylinder 1011 extends, it will synchronously compress the second spring 1016 through the first movable block 1018; when the output end of the first cylinder 1011 retracts, under the reset action of the second spring 1016, it will drive the lever 1008 to rotate upward at the end near the first cylinder 1011.

[0041] It should be noted that the present invention can also directly drive the threaded sleeve to move up and down using an electric telescopic rod or an electric push rod; as to which method to achieve the upward and downward movement of the threaded sleeve, those skilled in the art can determine according to the actual situation, and this application does not make specific limitations, all of which are within the protection scope of this application.

[0042] Preferably, a second support column 1004 is installed on the fixed plate 1005. The second support column 1004 is fixedly connected to a handle plate 1003 via a connecting rod. The handle plate 1003 cooperates with the end of the long lever 1001 near the upper clamping mechanism 10. Specifically, the end of the long lever 1001 near the upper clamping mechanism 10 is hook-shaped and used to hook the round rod on the handle plate 1003. In addition, a limit post and a limit plate 1006 are respectively provided on the fixed plate 1005 and the upper disc 4. The limit post and the limit plate 1006 are used to limit the movement stroke of the second lever 1008 and the long lever 1001, respectively.

[0043] For further details, please refer to Figures 13-15 The threaded sleeve 1023 is used to connect to the upper end of the second central shaft 1024. The outer surface of the second central shaft 1024 slides in fit with the inner surface of the second outer shaft 1025. The upper end of the second outer shaft 1025 is mounted on the fixing plate 1005 by fastening bolts. A guide sleeve 1027 is provided on the outer side of the second outer shaft 1025. A linear bearing 1026 is provided between the guide sleeve 1027 and the second outer shaft 1025. The guide sleeve 1027 is mounted on the upper disc 4. In addition, the bottom end of the second central shaft 1024 extends to the clamping head 1030, which is used to clamp the upper end of the workpiece transferred to the processing station. The clamping head 1030 is engaged with the clamping head mounting seat 1031, which is mounted on the bottom end of the second outer shaft 1025. The bottom circumferential surface of the clamping head 1030 is provided with a strip-shaped groove, and the outer surface of the clamping head 1030 is wedge-shapedly engaged with the bottom end of the second central shaft 1024. Therefore, when the threaded sleeve 1023 drives the second central shaft 1024 to move downward, the second central shaft 1024 will squeeze the clamping head 1030, so that the clamping head 1030 can deform and clamp the upper end of the workpiece; conversely, when the threaded sleeve 1023 drives the second central shaft 1024 to move upward, the second central shaft 1024 no longer squeezes the clamping head 1030, and the clamping head 1030 will reset and release the workpiece.

[0044] Preferably, the upper clamping mechanism 10 further includes a second cylinder 1013, which is mounted on a second cylinder mounting plate 1012, which is mounted on the top of the support base 1007. A second inner shaft 1028 is fixedly connected to the output end of the second cylinder 1013, and the second inner shaft 1028 is disposed within the second central shaft 1024. A top-loading head 1029 is connected to the end of the second inner shaft 1028 away from the second cylinder 1013. When the clamping head 1030 releases the workpiece, the invention can activate the second cylinder 1013, which drives the top-loading head 1029 downwards. The top-loading head 1029 pushes the workpiece out of the clamping head 1030, facilitating the workpiece's detachment from the clamping head 1030 and preventing the workpiece from falling downwards due to its own weight after being contaminated with metal cutting oil.

[0045] It should be noted that the ejector head 1029 can be designed to extend into the clamping head 1030, or it can be designed not to extend into the clamping head 1030. Those skilled in the art can determine the appropriate design based on the specific circumstances. For example, when the workpiece is long enough and its upper end penetrates the clamping head 1030, the ejector head 1029 can be designed not to extend into the clamping head 1030. Conversely, when the workpiece is short enough and its upper end does not penetrate the clamping head 1030, the ejector head 1029 can be designed to extend into the clamping head 1030.

[0046] Please see Figure 13 To facilitate the receiving mechanism 11 in receiving finished workpieces delivered by high-pressure oil jets, a guide seat 1032 is installed on the outer surface of the bottom end of the second outer shaft 1025. The guide seat 1032 is slidably engaged with the second guide rod 1033, which is mounted on the bottom end of the guide sleeve 1027. A fixing block 1103 is installed on the outer surface of the guide seat 1032, and a drive rod 1104 is mounted on the fixing block 1103. Furthermore, the bottom end of the guide sleeve 1027 is rotatably connected to one end of the receiving head 1101. The receiving head 1101 is equipped with a receiving tube 1102 and has a limiting groove 1105. One end of the drive rod 1104 is slidably engaged with the limiting groove 1105. After the sawing mechanism 6 cuts the workpiece, the second outer shaft 1025 will drive the guide seat 1032 to move upward synchronously, so that the drive rod 1104 slides upward along the limiting groove 1105, thereby making the receiving mechanism 11 approach the finished workpiece synchronously, so that the receiving mechanism 11 can receive the finished workpiece sent by the high-pressure oil.

[0047] The working process of this invention is as follows: In specific use, the invention drives the cam 903 to rotate via the drive mechanism 9. The rotated cam 903 synchronously drives the upper drive wheel 913 to move upwards and the lower drive wheel 905 to move downwards. Simultaneously, the middle disc 3 transports the alloy part to be processed to the processing station. The upward movement of the upper drive wheel 913 drives the upper clamping mechanism 10 to move downwards to clamp the workpiece. The downward movement of the lower drive wheel 905 drives the sawing mechanism 6 to approach the workpiece for sawing operations. This achieves the synchronous execution of the two actions: the upper clamping mechanism 10 moving downwards to clamp the workpiece and the sawing mechanism 6 approaching the workpiece to saw it. This ensures that the upper clamping mechanism 10 can simultaneously clamp the workpiece while sawing it. After the finished workpiece is sawn off, the upper clamping mechanism 10 moves upwards... The second outer shaft 1025 drives the guide seat 1032 to move upward synchronously, causing the drive rod 1104 to slide upward along the limiting groove 1105, thereby causing the receiving mechanism 11 to move closer to the finished workpiece synchronously. At this time, the output end of the first cylinder 1011 extends, driving the second lever 1008 to swing downward, thereby lifting the threaded sleeve 1023 and the second central shaft 1024. The second central shaft 1024 no longer squeezes the clamping head 1030, causing the clamping head 1030 to release the clamped workpiece. The finished workpiece falls downward under the action of gravity, and then the high-pressure oil nozzle sprays high pressure. High-pressure oil is used to propel the finished workpiece to the receiving mechanism 11, which then transports the workpiece out, thus completing the workpiece sawing and collection process. It is worth noting that when the clamping head 1030 releases the workpiece, the second cylinder 1013 is activated simultaneously. The second cylinder 1013 drives the ejector head 1029 to move downwards. The ejector head 1029 ejects the workpiece from the clamping head 1030, making it easier for the workpiece to detach from the clamping head 1030 and preventing it from falling downwards due to its own weight after being contaminated with metal cutting oil.
