Description

A smart turning device to prevent chip flying Technical Field

[0001] This invention relates to the field of piston head machining technology, specifically to an intelligent turning device that prevents chip splashing. Background Technology

[0002] Grinding is expensive, has a long lead time, low batch processing efficiency, and high overall cost. To address these drawbacks, the company plans to replace grinding with precision lathes. This will be achieved through high-precision tooling and high-precision lathes, resulting in more efficient machining. However, turning generates a significant amount of debris. This debris not only causes equipment wear but also poses safety risks if it hits operators.

[0003] To address this, Chinese Patent No. CN116140655B discloses a turning device for machining the ring groove of a low-speed machine piston head. During use, the device contacts the outer wall of the piston head body through the arc-shaped chip inlet in the transparent chip guide cover. At the same time, the connection between the arc-shaped chip inlet and the outer wall of the piston head body is sealed by the connecting component, so that the contact position between the cutting head and the piston head body is in a relatively closed space. This restricts the chips generated during turning from being discharged through the chip outlet of the transparent chip guide cover, making it less likely for chips to fly off, which would make it difficult to clean and collect later and could easily cause damage to the equipment or cause personal injury to the operator due to flying chips.

[0004] However, in order to prevent chips from escaping from the contact point between the chip guide and the workpiece, traditional turning equipment needs to control the synchronous rotation of the parts and the workpiece.

[0016] The advantages of this invention compared to the prior art are:

[0017] 1. This invention achieves the function of preventing chip splashing during turning through a frame, chip guide, telescopic mechanism, and control mechanism, actively collecting chips through the chip guide. This solves the problem of increased wear on parts caused by the chip guide rotating with the workpiece in existing turning devices. In operation, the operator first places the workpiece, equipped with auxiliary and counterweight fixtures, onto the positioning clamping fixture. Then, the workpiece and the positioning clamping fixture are connected by bolts. Next, the rotary drive assembly is activated, driving the positioning clamping fixture to rotate, which in turn rotates the workpiece. Then, the operator controls the chip guide to move closer to the workpiece via the telescopic mechanism until the rollers on the chip guide abut against the workpiece. The control mechanism then extends the cutting head, performing the turning operation.

[0018] 2. This invention achieves the function of controlling the movement of the chip guide cover through a guide rail, a movable bracket, a first linear driver, and a buffer assembly. The buffer assembly ensures that the pressure between the chip guide cover and the workpiece remains within a specified range, preventing damage to the chip guide cover due to fluctuations in pressure. When the support wheel on the chip guide cover contacts the workpiece and its movement is obstructed, the buffer assembly is compressed. When the buffer assembly is compressed to a specified range, the first linear driver stops. The expansion and contraction of the buffer assembly ensures that the chip guide cover remains in contact with the workpiece. Furthermore, when the buffer assembly is compressed to the specified range, the control assembly controls the cutting head to extend. At this point, chips are stably collected by the chip guide cover, preventing chip splashing that would occur if turning was performed before the chip guide cover was in contact with the workpiece.

[0019] 3. This invention achieves the function of controlling the extension and retraction of the cutting head through a movable seat, a first support rod, a second linear actuator, a guide frame, and a linear drive assembly. Furthermore, the cooperation between the movable seat and the first support rod enables control of the cutting depth and cutting position. During the cutting process, the linear drive assembly controls the movable seat to rise and fall along the guide frame, which in turn drives the first support rod to rise and fall, adjusting the cutting position for precise cutting.

Detailed Implementation

[0034] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0035] Referring to Figures 1-4 and 13: A smart turning device for preventing chip splashing includes a frame 1, a chip guide cover 2 on the frame 1, two rotating shafts 21 on the chip guide cover 2, and support wheels 211 sleeved on the rotating shafts 21; a cutting head 22 is provided inside the chip guide cover 2; the frame 1 is provided with a telescopic structure and a control mechanism 4, which are used to control the movement of the chip guide cover 2 and the cutting head 22, respectively.

[0036] This invention achieves the function of preventing chip splashing during turning through a frame 1, a chip guide 2, a telescopic mechanism 3, and a control mechanism 4, and actively collects chips through the chip guide 2. Furthermore, the chip guide 2 abuts against the workpiece 7 via two support wheels 211, eliminating the need for synchronous rotation with the workpiece 7 during its rotation, thus preventing excessive wear and ensuring stable chip collection. The frame 1 is equipped with a positioning clamping fixture 11 and a rotary drive assembly 12 for driving the positioning clamping fixture 11 to rotate. Auxiliary fixtures 71 and counterweight fixtures 72 are respectively fitted onto both ends of the workpiece 7 to improve the stability of the workpiece 7's rotation. In operation, the operator first places the workpiece 7, fitted with the auxiliary fixtures 71 and counterweight fixtures 72, onto the positioning clamping fixture 11, then connects the workpiece 7 and the positioning clamping fixture 11 with bolts, and then activates the rotary drive assembly 12, which drives the positioning clamping fixture 11 to rotate, thereby rotating the workpiece 7. Then, the operator controls the chip guide 2 to move closer to the workpiece 7 via the telescopic mechanism 3 until the rollers on the chip guide 2 come into contact with the workpiece 7. The control mechanism 4 controls the cutting head 22 to extend, and turning is performed through the cutting head 22.

[0037] Referring to Figures 2 and 3: The telescopic mechanism 3 includes a guide rail 31, a movable bracket 32, a first linear driver 33, and a buffer assembly 34; the guide rail 31 is mounted on the frame 1, and the movable bracket 32 ​​is slidably mounted on the guide rail 31; the first linear driver 33 is mounted on the guide rail 31, and the first linear driver 33 is used to drive the movable bracket 32 ​​to move; the movable bracket 32 ​​is connected to the chip guide cover 2 through the buffer assembly 34.

[0038] This invention achieves the function of controlling the movement of the chip guide 2 through the guide rail 31, the movable bracket 32, the first linear actuator 33, and the buffer assembly 34. Furthermore, the buffer assembly 34 ensures that the pressure between the chip guide 2 and the workpiece 7 is within a specified range, preventing damage to the chip guide 2 due to fluctuations in pressure. In operation, the operator first drives the movable bracket 32 ​​towards the workpiece 7 using the first linear actuator 33. The movable bracket 32, through the buffer assembly 34, moves the chip guide 2. When the support wheel 211 on the chip guide 2 contacts the workpiece 7, its movement is hindered, and the buffer assembly 34 is compressed. When the buffer assembly 34 is compressed to a specified range, the first linear actuator 33 stops. The expansion and contraction of the buffer assembly 34 ensures that the chip guide 2 remains in contact with the workpiece 7. When the buffer assembly 34 is compressed to the specified range, the control assembly 54 controls the cutting head 22 to extend. At this point, the chip guide 2 stably collects chips, preventing chip splashing during turning operations when the chip guide 2 is not in contact with the workpiece 7.

[0039] Referring to Figures 1, 2, and 5: the control mechanism 4 includes a movable seat 41, a first support rod 42, a second linear actuator 43, a guide frame 44, and a linear drive assembly 45; the movable seat 41 is mounted on the frame 1, and the first support rod 42 is slidably mounted on the movable seat 41; the second linear actuator 43 is used to drive the first support rod 42 to move horizontally relative to the movable seat 41; the guide frame 44 is mounted on the frame 1, and the movable seat 41 is slidably engaged with the guide frame 44; the linear drive assembly 45 is used to drive the movable seat 41 to move up and down along the guide frame 44.

[0040] This invention achieves the function of controlling the extension and retraction of the cutting head 22 through the movable seat 41, the first support rod 42, the second linear actuator 43, the guide frame 44, and the linear drive assembly 45. Furthermore, the cooperation between the movable seat 41 and the first support rod 42 enables control of the cutting depth and cutting position of the cutting head 22. When machining the workpiece 7, it is necessary to flexibly control the movement of the cutting head 22, and to prevent chips from flying out, it is also necessary to keep the cutting head 22 within the chip guide 2. Therefore, the position of the cutting head 22 is controlled by the movement of the first support rod 42. In the working state, the operator drives the first support rod 42 horizontally via the second linear actuator 43, bringing the cutting head 22 closer to the workpiece 7. During the cutting process, the linear drive assembly 45 controls the movable seat 41 to rise and fall along the guide frame 44, which in turn drives the first support rod 42 to rise and fall, adjusting the cutting position for precise cutting. Instead of a hydraulic cylinder, the control mechanism 4 employs a second linear actuator 43 and a linear drive assembly 45. This allows for more precise horizontal movement and vertical adjustment of the cutting head 22, meeting the precise control requirements for depth of cut and cutting position during turning. It also ensures that the cutting head 22 remains within the chip guide 2 to prevent chip splashing. This drive method provides more stable operation. Due to the higher displacement accuracy of the electric drive, the movement distance of the cutting head 22 can be controlled more precisely, avoiding the positional deviation of the cutting head 22 caused by hydraulic oil pressure fluctuations, thus ensuring the accuracy of the cutting process. Furthermore, the electric drive keeps the cutting head 22 stably within the coverage area of ​​the chip guide 2, effectively preventing chip splashing. Simultaneously, the electric drive has a faster response speed, allowing for more timely control of the movable seat 41 along the guide frame 44 via the linear drive assembly 45 when adjusting the cutting position, thereby driving the first support rod 42 and the cutting head 22 to complete the action and improving machining efficiency.

[0041] Referring to Figures 2, 6, and 7: the buffer assembly 34 includes a guide post 341, a telescopic rod 342, and a first elastic element 343; the guide post 341 is disposed on the movable bracket 32, and the guide post 341 is slidably engaged with the chip guide cover 2; the telescopic rod 342 is connected to the movable bracket 32, and the first elastic element 343 is sleeved on the telescopic rod 342, with both ends of the first elastic element 343 connected to the chip guide cover 2 and the movable bracket 32, respectively.

[0042] This invention utilizes a guide post 341, a telescopic rod 342, and a first elastic element 343 to buffer the impact on the chip guide cover 2 during its extension and retraction. The front end of the telescopic rod 342 slides in conjunction with the chip guide cover 2. In operation, the first linear actuator 33 drives the movable support 32 to move along the guide rail 31, and the movable support 32 pushes the chip guide cover 2 to move via the first elastic element 343. During movement, the guide post 341 and the telescopic rod 342 stably support the chip guide cover 2, stabilizing its extension and retraction path. After the support wheel 211 on the chip guide cover 2 abuts against the workpiece 7, the first elastic element 343 is gradually compressed. Once the deformation of the first elastic element 343 is within a specified range, the driving of the first linear actuator 33 stops. Simultaneously, the control mechanism 4 controls the extension of the cutting head 22 for turning operations. Compared to existing technologies, this invention has a simple and compact structure, eliminating the need for complex components such as hydraulic pipelines and control valves, saving installation space between the movable bracket 32 ​​and the chip guide cover 2, and adapting to the overall design of the device; it also has lower maintenance costs, as components such as the first elastic element 343 are easy to replace after wear, avoiding potential hydraulic system malfunctions such as oil leakage and pipeline blockage, thus reducing maintenance workload; its buffering performance is stable and unaffected by environmental factors such as temperature and pressure, maintaining a consistent buffering effect under various turning conditions, ensuring that the deformation of the first elastic element 343 is within a specified range, thereby precisely coordinating with the start and stop control of the first linear actuator 33 to achieve timely extension of the cutter head 22 after the chip guide cover 2 is in place, ensuring machining safety and chip collection effectiveness.

[0043] Referring to Figures 5, 8, and 9: A vertical plate 5 is provided on the frame 1, and a mounting plate 51 and a first guide rod 52 are provided on the vertical plate 5; a baffle is connected to the mounting plate 51, and a first straight groove 421 that cooperates with the baffle is opened on the first support rod 42; the first guide rod 52 is connected to the vertical plate 5, and the mounting plate 51 and the first guide rod 52 are slidably engaged; a second elastic element 521 is sleeved on the first guide rod 52, and the two ends of the second elastic element 521 are respectively connected to the mounting plate 51 and the vertical plate 5; a limiting component 53 for limiting the movement of the mounting plate 51 is provided on the vertical plate 5.

[0044] This invention achieves the function of restricting the movement of the first support rod 42 through the mounting plate 51, the first guide rod 52, and the limiting component 53. After the chip guide cover 2 abuts against the workpiece 7 and the compression of the first elastic element 343 reaches a specified value, the movement restriction of the mounting plate 51 by the limiting component 53 is released, and then the control mechanism 4 controls the cutter head 22 to extend, maintaining the chip guide cover 2's collection of debris. A limiting block 522 for limiting the movement range of the mounting plate 51 is provided at the end of the first guide rod 52 away from the mounting plate 51. In the working state, the stop block 511 cooperates with the first straight groove 421, restricting the movement of the mounting plate 51 through the limiting component 53, and further restricting the extension of the first support rod 42 through the stop block 511. When the support wheel 211 on the chip guide cover 2 abuts against the workpiece 7, and the first elastic element 343 is compressed to a specified length, the movement restriction of the mounting plate 51 by the limiting component 53 is released. The mounting plate 51 moves under the elastic force of the second elastic element 521, and the mounting plate 51 drives the stop block 511 to move, causing the stop block 511 to separate from the first straight groove 421, thus releasing the movement restriction of the first support rod 42. Then, the movement of the cutting head 22 is controlled by the control mechanism 4 to perform turning. Compared to existing technologies, the mechanical limiting structure consisting of mounting plate 51, first guide rod 52, second elastic element 521, and limiting component 53, rather than the limiting method driven by hydraulic cylinder, precisely controls the movement permission of the first support rod 42 through mechanical linkage. This ensures that the cutter head 22 can only extend after the chip guide cover 2 and the workpiece 7 are stably abutted by the support wheel 211 and the compression of the first elastic element 343 reaches a specified value. This mechanically avoids the risk of chip splashing caused by the cutter head 22 moving prematurely before the chip guide cover 2 is in place.

[0045] Referring to Figures 8 and 9: the limiting component 53 includes a side plate 531, a mounting base 532, a locking block 533, and a third elastic member 534; the side plate 531 is disposed on the upright plate 5, and the mounting base 532 is disposed on the side plate 531; the locking block 533 is slidably mounted on the mounting base 532, and the two ends of the third elastic member 534 are respectively connected to the locking block 533 and the mounting base 532; the upright plate 5 is provided with a control component 54 for controlling the retraction of the locking block 533.

[0046] This invention achieves the function of restricting the movement of the mounting plate 51 through the side plate 531, mounting base 532, locking block 533, and third elastic element 534. The locking block 533 has an arc surface. In the working state, when the locking block 533 is in the extended state and abuts against the mounting plate 51, it restricts the movement of the mounting plate 51. When the support wheel 211 on the chip guide cover 2 abuts against the workpiece 7 and the buffer assembly 34 is compressed to a specified range, the locking block 533 is controlled to retract by the control assembly 54. After the locking block 533 separates from the mounting plate 51, the mounting plate 51 drives the stop block 511 to move under the elastic force of the second elastic element 521. After the stop block 511 separates from the first straight groove 421, the first support rod 42 is controlled to extend by the linear drive assembly 45, and the tool head 22 is controlled to move by the second linear driver 43 and the linear drive assembly 45 to perform turning machining on the workpiece 7.

[0047] Referring to Figures 1 and 10: The movable bracket 32 ​​is provided with a mounting frame 6, and the mounting frame 6 is provided with a movable rod 61 and a connecting rod assembly 62; the chip guide cover 2 is provided with a push plate 23 at one end near the movable bracket 32; the movable rod 61 is provided with an abutment plate 611 at one end near the chip guide cover 2, and the other end of the movable rod 61 is connected to the control component 54 through the connecting rod assembly 62; as the chip guide cover 2 and the movable bracket 32 ​​approach each other, the push plate 23 on the chip guide cover 2 pushes the abutment plate 611 of the movable rod 61.

[0048] This invention achieves the function of automatically releasing the movement restriction of the mounting plate 51 by the restrictive component 53 through the movable rod 61 and the connecting rod assembly 62. In the working state, when the support wheel 211 contacts the workpiece 7, the first elastic element 343 gradually contracts, and the chip guide 2 gradually approaches the movable bracket 32. After the push plate 23 on the chip guide 2 contacts the abutment plate 611 on the movable rod 61, it pushes the movable rod 61. The movable rod 61 drives the control mechanism 4 through the connecting rod assembly 62. The control mechanism 4 releases the movement restriction of the mounting plate 51 by the restrictive component 53, and then automatically controls the stop block 511 to separate from the first straight groove 421, allowing subsequent feed actions to proceed.

[0049] Referring to Figures 10 and 11: the linkage assembly 62 includes a main rod 621, a third guide rod 622, a movable hinge seat 623, and a secondary rod 624; the main rod 621 is vertically mounted on the mounting frame 6 and is connected to the control assembly 54 in a transmission manner; the third guide rod 622 is mounted on the mounting frame 6, and the main rod 621 and the third guide rod 622 are slidably engaged; the movable hinge seat 623 is slidably mounted on the mounting frame 6, and the movable rod 61 is connected to the movable hinge seat 623; the two ends of the secondary rod 624 are hinged to the main rod 621 and the movable hinge seat 623, respectively.

[0050] This invention achieves the function of driving the control component 54 via the movable rod 61 through the main rod 621, the movable hinge seat 623, and the auxiliary rod 624. The mounting frame 6 is provided with a fixed hinge seat 625. A sliding groove is formed at the end of the main rod 621, and an auxiliary rod 624 is hinged to the fixed hinge seat 625. The auxiliary rod 624 is slidably hinged to the sliding groove of the main rod 621. When the push plate 23 on the chip guide shroud 2 pushes the abutment rod, the abutment plate 611 drives the movable rod 61 to move, and the movable rod 61 pushes the movable hinge seat 623 to move. The movable hinge seat 623 pulls the main rod 621 through the auxiliary rod 624, and the main rod 621 moves downward under the pulling force. During this process, the main rod 621 drives the control component 54, and the control component 54 releases the movement restriction of the mounting plate 51 by the limiting component 53.

[0051] Referring to Figures 10 and 11: the control assembly 54 includes a push rod 541 and a connecting plate 542; the top end of the push rod 541 is provided with a connecting seat 5411, which is connected to the main rod 621; the connecting plate 542 is provided with a second guide rod 5421 connected to the locking block 533; the bottom end of the push rod 541 is provided with a wedge 5412 for pushing the connecting plate 542.

[0052] This invention achieves the function of driving the movement of the locking block 533 through the push rod 541 and the connecting plate 542. A third linear actuator for driving the mounting plate 51 to reset is built into the frame 1. In operation, when the push plate 23 on the chip guide shroud 2 pushes the movable rod 61 to move, the movable rod 61 pulls the main rod 621 downwards via the auxiliary rod 624, and the main rod 621 drives the connecting seat 5411 downwards. The connecting seat 5411 drives the wedge block 5412 downwards via the push rod 541, and then the wedge block 5412 presses against the connecting plate 542. The connecting plate 542 drives the locking block 533 to move via the second guide rod 5421, and the third elastic element 534 is compressed, thereby controlling the locking block 533 to separate from the mounting plate 51. After processing, the first support rod 42 is reset by the control mechanism 4, and then the mounting plate 51 is reset by the third linear driver. During the reset process, the mounting plate 51 presses the arc surface of the locking block 533 until the mounting plate 51 completely passes through the locking block 533, and the locking block 533 restricts the movement of the mounting plate 51 again.

[0053] Referring to Figures 5 and 12: the control mechanism 4 further includes a second support rod 46, on which a fourth guide rod 461 is provided that slides with the first support rod 42. A fourth elastic element 462 is sleeved on the fourth guide rod 461, and the two ends of the fourth elastic element 462 are respectively connected to the first support rod 42 and the second support rod 46. A second straight groove 422 and a third straight groove 463 are respectively provided on the first support rod 42 and the second support rod 46. The driving end of the second linear actuator 43 is connected to a gripper 431 for clamping the first support rod 42 and the second support rod 46, and the second straight groove 422 and the third straight groove 463 are used to cooperate with the gripper 431.

[0054] This invention achieves the function of adjusting the clamping position of the second linear actuator 43 through the second support rod 46 and the gripper 431. During rough machining of the workpiece 7, the gripper 431 clamps the third straight groove 463 on the second support rod 46, and then the second linear actuator 43 pushes the second support rod 46 to move. The second support rod 46, through the fourth elastic element 462, pushes the first support rod 42 to move, and the first support rod 42 drives the cutting head 22 to move for cutting. During machining, the fourth guide rod 461 and the fourth elastic element 462 act as a buffer to protect the cutting head 22. During finish machining, the gripper 431 is controlled to clamp the second straight groove 422 on the first support rod 42, and then the second linear actuator 43 and the gripper 431 directly drive the first support rod 42 to move, thus precisely controlling the position of the cutting head 22.

[0055] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
