Description

Technical Field

[0001] This invention relates to the field of turning machine tool technology, and more specifically to a turning machine tool with a rigid cutting direct drive rotary table. Background Technology

[0002] Turning machine tools, as fundamental equipment in the field of machining, are widely used in the machining of rotating parts such as shafts and discs. Their working principle typically involves a drive motor rotating the workpiece while a cutting tool on the tool post feeds it linearly or along curves, thus removing excess material. During the turning process, metal chips and turning fluid used for cooling and lubrication are generated.

[0003] In existing technologies, the common practice for cleaning chips and coolant inside the working cavity of turning machine tools relies on manual cleaning by the operator during machining breaks or after the machining process. This method is inefficient and cannot achieve real-time cleaning during machining, affecting automated continuous production. Some higher-end machine tools are equipped with independent cleaning devices, such as additional air or liquid spraying systems, and scrapers or chip conveyors driven by independent motors. However, these solutions have certain drawbacks: First, they require an additional power source, increasing the overall energy consumption, manufacturing costs, and control system complexity of the machine. Second, the independent drive cleaning device lacks direct mechanical linkage between its movement and the spindle machining motion, and the cleaning rhythm may not be optimally matched with the machining conditions (such as spindle speed), potentially leading to wasted power or untimely cleaning. Third, the additional devices often occupy valuable internal or external space of the machine tool, making the machine tool's structural layout less compact, thus requiring further improvement. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a turning machine tool with a rigid cutting direct-drive rotary table, solving the problems mentioned in the background art.

[0005] The solution of the present invention to the above-mentioned technical problems is as follows: This invention provides a turning machine tool with a rigid cutting direct-drive rotary table, including a lathe body, a collection box at the bottom of the lathe body, a moving platform on the lathe body, a tool holder mounted on the moving platform, a housing mounted on the side of the lathe body, a drive motor installed inside the housing, a rotating shaft at the output end of the drive motor, and a rotary table body mounted on the rotating shaft, and further comprising: The reciprocating conversion mechanism, the airflow generating mechanism, and the transmission mechanism are all housed within the chassis; Cleaning component one and cleaning component two are both disposed within the lathe body; A connecting mechanism is provided on the lathe body; The drive motor drives the turntable body to rotate for turning via the rotating shaft, and simultaneously drives the reciprocating conversion mechanism and the transmission mechanism to operate; the reciprocating conversion mechanism drives the second cleaning component to reciprocate within the lathe body for scraping and cleaning, and drives the first cleaning component to move synchronously for scraping and cleaning via the connecting mechanism; the transmission mechanism drives the airflow generating mechanism to generate airflow, and supplies the airflow to the first cleaning component and the second cleaning component for spray cleaning; the scraped and sprayed debris and turning fluid fall into the collection box.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the reciprocating conversion mechanism includes a mounting bracket fixedly installed inside the chassis, with a guide groove provided in the mounting bracket. The reciprocating conversion mechanism also includes a connecting wheel fixedly installed on the rotating shaft, with a cam groove provided on the connecting wheel. A follower is fitted inside the cam groove, and a guide block is installed at the bottom end of the follower. An auxiliary wheel is rotatably installed inside the guide block. The guide block is slidably disposed in the guide groove via the auxiliary wheel. A push rod is installed at the bottom end of the guide block, and the end of the push rod facing away from the guide block is fixedly connected to the second cleaning component.

[0008] The beneficial effects of adopting the above-mentioned further solutions are: The reciprocating conversion mechanism reliably converts the continuous rotational motion of the main shaft into the linear reciprocating motion of the guide block and push rod through the engagement of the cam groove on the connecting wheel and the guide groove on the mounting bracket. This provides a direct mechanical drive for the periodic scraping action of the cleaning component two, eliminating the need for an additional motor or control system.

[0009] Furthermore, the airflow generating mechanism includes a fixed pipe fixedly installed inside the chassis, a piston slidably sleeved inside the fixed pipe, a fixed block mounted on the piston via a connecting bracket, the fixed block being connected to the transmission mechanism, an air inlet pipe 1 and an air inlet pipe 2 with an air inlet one-way valve connected to the side wall of the fixed pipe, an air outlet pipe 1 and an air outlet pipe 2 with an air outlet one-way valve connected to the end of the fixed pipe opposite to the air inlet pipe 1 and the air inlet pipe 2, an air outlet pipe 1 connected to the cleaning component 2, and an air outlet pipe 2 connected to the cleaning component 1.

[0010] The beneficial effects of adopting the above-mentioned further solutions are: The airflow generating mechanism utilizes the reciprocating motion of a piston within a fixed tube, in conjunction with one-way valves on the inlet and outlet air pipes, to form a self-driven air pump. Its simple structure effectively converts mechanical energy into compressed airflow, providing a stable air source for jet cleaning. Through mechanical linkage air supply, it avoids the need for independent air sources such as external air compressors, reducing equipment costs and energy consumption.

[0011] Furthermore, the transmission mechanism includes a driving gear fixedly mounted on the rotating shaft and a driven gear meshing with the driving gear. A mounting shaft is mounted on the driven gear, and the mounting shaft is rotatably mounted in the housing via a base. A connecting rod one is mounted on the mounting shaft, and the connecting rod one is connected to a connecting rod two via a pin. The connecting rod two is connected to a fixed block in the airflow generating mechanism via a pin.

[0012] The beneficial effects of adopting the above-mentioned further solutions are: The transmission mechanism transmits power through gear meshing, and then converts the rotational motion into the linear reciprocating motion of the fixed block through connecting rod one and connecting rod two. This transmission method can accurately transmit the rotational power of the main shaft to the piston of the airflow generating mechanism, ensuring that the air supply rhythm matches the main shaft speed.

[0013] Furthermore, the cleaning component includes a partition plate that is slidably disposed within the lathe body. A slanted baffle plate is installed at the top of the partition plate, and a blowpipe is installed at the side end of the partition plate. The blowpipe has multiple air outlets.

[0014] The beneficial effects of adopting the above-mentioned further solutions are: When the partition moves, it can scrape off the debris and liquid adhering to the inner wall of the lathe body; the inclined baffle at the top can effectively prevent debris from crossing the partition and entering the non-cleaning area; the blow pipe at the side and its air outlet can concentrate and direct the airflow to further blow away the fine debris and droplets remaining after scraping, achieving a dual cleaning effect of scraping and blowing.

[0015] Furthermore, the cleaning component two includes a partition two that is slidably disposed within the lathe body, a slanted baffle two installed at the top of the partition two, and a blowpipe two installed at the side end of the partition two. The blowpipe two has multiple air outlets, and the partition two is connected to the reciprocating conversion mechanism.

[0016] The beneficial effects of adopting the above-mentioned further solutions are: Cleaning component two corresponds to cleaning component one and together they form a complete cleaning surface. Partition two is directly driven by the reciprocating conversion mechanism for active scraping, and the inclined baffle two on it also serves to prevent spillage. The blow pipe two is responsible for blow cleaning on this side. The coordinated work of the two cleaning components can achieve cleaning of the working area inside the lathe body.

[0017] Furthermore, the connecting mechanism includes a transmission gear rotatably mounted on the lathe body, and a guide frame 1 and a guide frame 2 respectively mounted on the partition 2 and the partition 1. The top end of the guide frame 1 is equipped with a rack frame 1 that meshes with the transmission gear, and the bottom end of the guide frame 2 is equipped with a rack frame 2 that meshes with the transmission gear.

[0018] The beneficial effects of adopting the above-mentioned further solutions are: The connecting mechanism simultaneously engages two racks, rack one and rack two, in opposite directions via transmission gears, synchronously converting the active reciprocating motion of cleaning component two into the reciprocating motion of cleaning component one in the opposite direction. This ensures that the two cleaning components always work synchronously and symmetrically.

[0019] Furthermore, the air outlet end of the first air outlet pipe is connected to the inside of the second blow pipe of the second cleaning component.

[0020] The beneficial effects of adopting the above-mentioned further solutions are: Compressed air generated by the airflow generating mechanism is directly introduced into the cavity of the blowpipe 2 through the air outlet pipe 1, so that the air outlet of the blowpipe 2 can receive a direct airflow supply, thereby achieving the effect of blowpipe cleaning.

[0021] Furthermore, the air outlet end of the second air outlet pipe is connected to the inside of the first blow pipe of the first cleaning component.

[0022] The beneficial effects of adopting the above-mentioned further solutions are: The connection of the second air outlet pipe provides an airflow delivery channel for the first blow pipe of the first cleaning component, ensuring that both cleaning components can obtain an independent and sufficient air source for blowing operations, thereby improving the balance and reliability of the overall system's cleaning capacity.

[0023] Furthermore, the collection box is connected to the interior of the lathe body.

[0024] The beneficial effects of adopting the above-mentioned further solutions are: This structure allows scraped and blown debris and cutting fluid to be smoothly and directly discharged into the collection box below for centralized treatment under the action of gravity and airflow. This maintains the continuous cleanliness of the machining area inside the lathe body, avoids secondary pollution or cleaning, and facilitates the unified cleaning and maintenance of waste in the future.

[0025] As can be seen, the present invention provides a turning machine tool with a rigid cutting direct-drive rotary table. It has the following beneficial effects: By integrating the reciprocating conversion mechanism, transmission mechanism, airflow generation mechanism, cleaning component one, cleaning component two, and connecting mechanism into the lathe body and chassis, and directly mechanically linking them with the drive motor and rotating shaft as the power source, the functions of turning and cleaning maintenance are integrated. Specifically, while the rotating shaft drives the rotary table body to perform cutting, it drives the cleaning component two to reciprocate for mechanical scraping through the reciprocating conversion mechanism, and drives the cleaning component one to move synchronously in the opposite direction through the connecting mechanism, thereby achieving bidirectional and comprehensive scraping of the inner wall of the lathe body; on the other hand, it drives the airflow generator through the transmission mechanism. The system generates compressed airflow, which is then supplied to cleaning components one and two for directional blowing. This combined scraping and blowing cleaning method significantly improves the efficiency and cleanliness of removing debris and cutting fluid. The removed waste falls directly into the collection box under the action of gravity and airflow, achieving online and automatic collection. The entire cleaning process relies entirely on the rotational power of the spindle itself, without the need for additional independent motors, air pumps, or complex control systems. This results in a compact structure and reliable linkage, effectively solving the problems of low efficiency, reliance on external power, and loose structure in traditional lathe cleaning methods.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 14 As shown, the embodiments provided by the present invention are as follows: Example 1: A turning machine tool with a rigid cutting direct-drive rotary table includes a lathe body 1, a collection box 101 at the bottom of the lathe body 1, a moving platform 3 on the lathe body 1, a tool holder 301 mounted on the moving platform 3, a housing 2 on the side of the lathe body 1, a drive motor 201 installed inside the housing 2, a rotating shaft 202 at the output end of the drive motor 201, and a rotary table body 203 mounted on the rotating shaft 202. The machine tool also includes: The reciprocating conversion mechanism 4, the airflow generating mechanism 5, and the transmission mechanism 6 are all housed inside the casing 2; Cleaning component 1 7 and cleaning component 2 8 are both installed inside the lathe body 1; The connecting mechanism 9 is mounted on the lathe body 1; The drive motor 201 drives the turntable body 203 to rotate for turning via the rotating shaft 202, and simultaneously drives the reciprocating conversion mechanism 4 and the transmission mechanism 6 to operate; the reciprocating conversion mechanism 4 drives the second cleaning component 8 to reciprocate within the lathe body 1 for scraping and cleaning, and drives the first cleaning component 7 to move synchronously for scraping and cleaning via the connecting mechanism 9; the transmission mechanism 6 drives the airflow generating mechanism 5 to generate airflow, and supplies the airflow to the first cleaning component 7 and the second cleaning component 8 respectively for spray cleaning; the scraped and sprayed debris and turning fluid fall into the collection box 101; The reciprocating conversion mechanism 4 includes a mounting bracket 401 fixedly installed inside the chassis 2. A guide groove 404 is provided inside the mounting bracket 401. The reciprocating conversion mechanism 4 also includes a connecting wheel 402 fixedly installed on the rotating shaft 202. A cam groove 403 is provided on the connecting wheel 402. A follower 405 is fitted inside the cam groove 403. A guide block 406 is installed at the bottom end of the follower 405. An auxiliary wheel 408 is rotatably installed inside the guide block 406. The guide block 406 is slidably disposed within the guide groove 404 via the auxiliary wheel 408. A push rod 407 is installed at the bottom of the guide block 406. The end of the push rod 407 away from the guide block 406 is fixedly connected to the second cleaning component 8. The reciprocating conversion mechanism 4 converts the continuous rotation of the main shaft 202 into the linear reciprocating motion of the guide block 406 and the push rod 407 through the cam groove 403 on the connecting wheel 402 and the guide groove 404 on the mounting bracket 401. This provides a direct mechanical drive for the periodic scraping action of the second cleaning component 8 without the need for an additional motor or control system. The collection box 101 is connected to the interior of the lathe body 1. This structure allows the scraped and blown debris and cutting fluid to be smoothly and directly discharged into the collection box 101 below for centralized treatment under the action of gravity and airflow. This keeps the internal machining area of ​​the lathe body 1 clean and avoids secondary pollution or cleaning. It also facilitates the unified cleaning and maintenance of waste in the future.

[0031] Example 2: In order to convert the rotational motion of the spindle into the airflow required for cleaning, for example, such as Figures 1 to 14 As shown, the present invention also includes: The airflow generating mechanism 5 includes a fixed pipe 501 fixedly installed inside the housing 2. A piston 508 is slidably sleeved inside the fixed pipe 501. A fixing block 507 is mounted on the piston 508 via a connecting bracket 506. The fixing block 507 is connected to the transmission mechanism 6. An intake pipe 1 504 and an intake pipe 2 505 with intake one-way valves are connected to the side wall of the fixed pipe 501. An exhaust pipe 1 502 with an exhaust one-way valve is connected to the end of the fixed pipe 501 opposite to the intake pipe 1 504 and the intake pipe 2 505. The second air outlet pipe 503 and the first air outlet pipe 502 are connected to the second cleaning component 8, and the second air outlet pipe 503 is connected to the first cleaning component 7. The airflow generating mechanism 5 uses the reciprocating motion of the piston 508 in the fixed pipe 501, in conjunction with the one-way valves on the inlet and outlet air pipes, to form a self-driven air pump. Its structure is simple and can effectively convert mechanical energy into compressed airflow, providing a stable air source for jet cleaning. Through mechanical linkage air supply, it avoids the need for an external air compressor or other independent air source, reducing equipment costs and energy consumption. The middle section of vent pipe 1 502 and vent pipe 2 503 needs to be made of a retractable corrugated pipe to accommodate the displacement of cleaning component 2 8 and cleaning component 1 7. The transmission mechanism 6 includes a drive gear 601 fixedly mounted on the rotating shaft 202 and a driven gear 602 meshing with the drive gear 601. A mounting shaft 605 is mounted on the driven gear 602. The mounting shaft 605 is rotatably mounted in the housing 2 via the base 603. A connecting rod 604 is mounted on the mounting shaft 605. The connecting rod 604 is connected to a connecting rod 606 via a pin. The connecting rod 606 is connected to a fixed block 507 in the airflow generating mechanism 5 via a pin. The transmission mechanism 6 transmits power through gear meshing, and then converts the rotational motion into the linear reciprocating motion of the fixed block 507 via the connecting rod 604 and the connecting rod 606. This transmission method can accurately transmit the rotational power of the main shaft to the piston 508 of the airflow generating mechanism 5, ensuring that the air supply rhythm matches the main shaft speed.

[0032] Example 3: To achieve effective scraping and directional blowing cleaning functions, for example, such as Figures 1 to 14 As shown, the present invention also includes: The cleaning component 7 includes a partition 701 slidably disposed inside the lathe body 1. A slanted baffle 702 is installed at the top of the partition 701, and a blowpipe 703 is installed at the side end of the partition 701. The blowpipe 703 has multiple air outlets 704. When the partition 701 moves, it can scrape off the debris and liquid adhering to the inner wall of the lathe body 1. The slanted baffle 702 at the top can effectively prevent debris from crossing the partition and entering the non-cleaning area. The blowpipe 703 at the side end and its air outlets 704 can concentrate and direct the airflow to further blow away the fine debris and liquid droplets remaining after scraping, achieving a dual cleaning effect of scraping and blowing. Cleaning component 2 8 includes a partition 2 801 slidably disposed inside the lathe body 1. A slanted baffle 2 802 is installed at the top of the partition 2 801, and a blowpipe 2 803 is installed at the side end of the partition 2 801. The blowpipe 2 803 has multiple air outlets 704. The partition 2 801 is connected to the reciprocating conversion mechanism 4. Cleaning component 2 8 corresponds to cleaning component 1 7 and together they form a complete cleaning surface. The partition 2 801 is directly driven by the reciprocating conversion mechanism 4 for active scraping. The slanted baffle 2 802 on it also serves to prevent spillage. The blowpipe 2 803 is responsible for blow cleaning on this side. The coordinated work of the two cleaning components can achieve cleaning of the working area inside the lathe body 1. The air outlet end of the air outlet pipe 502 is connected to the inside of the blow pipe 803 of the cleaning component 8. The compressed air generated by the airflow generating mechanism 5 is directly introduced into the cavity of the blow pipe 803 through the air outlet pipe 502, so that the air outlet 704 of the blow pipe 803 can obtain a direct airflow supply, thereby achieving the effect of blow cleaning. The air outlet end of the second air outlet pipe 503 is connected to the inside of the first blow pipe 703 of the first cleaning component 7. The connection of the second air outlet pipe 503 provides an airflow delivery channel for the first blow pipe 703 of the first cleaning component 7, ensuring that both cleaning components can obtain independent and sufficient air sources for blowing operations, thereby improving the balance and reliability of the cleaning capacity of the entire system.

[0033] Example 4: To ensure that the two cleaning components can perform synchronous reciprocating movements in opposite directions, thereby achieving full-range coordinated cleaning of the lathe's inner wall, for example, such as... Figures 1 to 14 As shown, the present invention also includes: The connecting mechanism 9 includes a transmission gear 903 rotatably mounted on the lathe body 1, and guide frames 901 and 905 respectively mounted on partition 801 and partition 701. A rack frame 902 meshing with the transmission gear 903 is mounted on the top of the guide frame 901, and a rack frame 904 meshing with the transmission gear 903 is mounted on the bottom of the guide frame 905. The connecting mechanism 9 simultaneously meshes the two rack frames 902 and 904 in opposite directions with the transmission gear 903, thereby synchronously converting the active reciprocating motion of the cleaning component 8 into the reciprocating motion of the cleaning component 7 in opposite directions. This ensures that the two cleaning components always work synchronously and symmetrically.

[0034] Working principle: Step 1: When turning is performed, the drive motor 201 starts and its output drives the rotating shaft 202 to rotate. The rotating shaft 202 directly drives the turntable body 203 on it to rotate, thereby driving the clamped workpiece to perform the main cutting motion. At the same time, the operator adjusts the position of the tool on the tool holder 301 through the moving platform 3 to turn the rotating workpiece. During this process, metal chips and turning fluid will be generated.

[0035] Step 2: While rotating the rotary table body 203, the rotating shaft 202 also drives the connecting wheel 402 of the reciprocating conversion mechanism 4 fixedly mounted on it to rotate synchronously. The cam groove 403 on the connecting wheel 402 rotates accordingly, driving the driven member 405 sleeved therein to produce regular radial displacement. The guide block 406 at the bottom of the driven member 405 is restricted to slide in the guide groove 404 of the fixed mounting bracket 401 through the auxiliary wheel 408 inside it, thereby accurately converting the rotational motion of the connecting wheel 402 into the stable linear reciprocating motion of the guide block 406. The guide block 406 transmits this reciprocating motion directly to the cleaning component 2 8 through the push rod 407 at its bottom, driving the cleaning component 2 8 to make reciprocating linear movements in the lathe body 1, using its physical structure to scrape off the debris and liquid attached to the inner wall.

[0036] Step 3: When cleaning component 2 8 reciprocates, it drives the guide frame 1 901 and rack frame 1 902 of the connecting mechanism 9 installed at its rear end to move synchronously. The linear motion of rack frame 1 902 drives the transmission gear 903 meshing with it to rotate. The transmission gear 903 then drives rack frame 2 904 meshing with it on the other side to move in the opposite direction. Rack frame 2 904 is connected to and drives cleaning component 1 7 through guide frame 2 905, so that cleaning component 1 7 and cleaning component 2 8 always maintain synchronous but opposite reciprocating motion, realizing bidirectional and coordinated scraping and cleaning of the inner wall of the lathe body 1.

[0037] Step 4: At the same time as the rotating shaft 202 rotates, the driving gear 601 of the transmission mechanism 6 on it rotates accordingly, and drives the driven gear 602 to rotate through meshing transmission. The driven gear 602 drives the connecting rod 604 to rotate through the mounting shaft 605, and then converts the rotational motion into linear reciprocating motion through the connecting rod 606, and drives the fixed block 507 of the airflow generating mechanism 5 to move up and down reciprocally. The fixed block 507 drives the piston 508 to perform reciprocating piston motion in the fixed tube 501 through the connecting frame 506.

[0038] When piston 508 moves downward: the volume of the cavity above piston 508 in fixed tube 501 increases, forming a negative pressure. Under the action of pressure, external air pushes open the one-way valve on the second air intake pipe 505 and enters the cavity. At the same time, the volume of the cavity below piston 508 decreases and the pressure increases. The air in the cavity pushes open the one-way valve on the first air outlet pipe 502 and is forced into the second cleaning component 8 through the first air outlet pipe 502, providing airflow for its blowing.

[0039] When piston 508 moves upward: the process is reversed. External air is drawn into the cavity below piston 508 through intake pipe 504, while the compressed air in the cavity above piston 508 opens the exhaust check valve on exhaust pipe 503 and is forced into cleaning assembly 7 through exhaust pipe 503, providing airflow for its blowing. This cycle continues, continuously supplying pulsed compressed air to both cleaning assemblies.

[0040] Step 5: Compressed air supplied to cleaning component 1 7 and cleaning component 2 8 enters the blow pipe 1 703 and blow pipe 2 803 on their side ends, respectively, and is concentrated and sprayed out at a certain angle through multiple air outlets 704 opened on the pipe wall. This airflow can effectively blow away the fine debris and droplets with strong adhesion that remain after scraping away from the inner wall of the machine tool, forming a composite cleaning effect with mechanical scraping as a supplement and airflow blowing as the main method. Finally, all the scraped and blown debris and turning fluid fall into the collection box 101 connected to the inside of the lathe body 1 under the guidance of gravity and airflow, and the collection is completed.
