Description

Technical Field

[0001] This invention relates to the field of forming machine tool technology, and in particular to a multi-station metal shaft cutting device. Background Technology

[0002] A multi-station shaft machining unit is an automated or semi-automated mechanical device used for efficient and continuous cutting of metal shaft parts. Its core design concept is to integrate multiple machining positions (stations) and corresponding functional modules, enabling the workpiece to sequentially complete multiple different cutting operations (such as turning external diameters, milling grooves, drilling, and grooving) in a single clamping or according to a predetermined flow, thereby significantly reducing repetitive clamping time and improving machining accuracy and production efficiency. A typical unit usually includes: a rotary fixture (such as a chuck or center) for clamping and driving the workpiece rotation; cutting tools (such as turning tools or milling cutters) for cutting the shaft; a feed mechanism (such as a linear module or slide table) for controlling the relative movement of the tool and the workpiece; and key components to achieve the "multi-station" function, such as a movable or indexable tool post, multiple spindle heads capable of synchronous or asynchronous machining, or multiple tool systems configured on a single spindle that can work alternately. These devices, through reasonable mechanical layout and control system coordination, realize the centralization and assembly of the processing process. They are important equipment in the modern mass production of shaft parts. During the processing, guide wheels are often set to assist the shaft in rotating to achieve auxiliary support and guidance, so as to avoid the workpiece bending and vibration caused by cutting force when cutting long or slender shafts, which would affect the processing accuracy and surface quality. However, in the existing devices, before clamping the shaft parts, that is, during the process of hoisting the shaft parts into the device, the shaft parts are very prone to collision with the guide wheels, which will lead to a decrease in the accuracy of the workpiece to be processed.

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] Example 1: Reference Figures 1-14 A multi-station metal shaft cutting device includes: a base 1, a rotary clamp 2, a cutting tool 3, a moving mechanism 4, a second moving mechanism 5, a tube 6, a rod 7, a guide wheel 8, and a spring 9. The rotary clamp 2 is connected to the base 1 to clamp both ends of the shaft. The moving mechanism 4 on the base 1 is connected to the cutting tool 3. The second moving mechanism 5 on the base 1 is connected to two tubes 6. Each end of the tube 6 is slidably connected to a rod 7. The end of the rod 7 is connected to a baffle 10 through the spring 9. The baffle 10 is connected to the tube 6. The end of the rod 7 away from the tube 6 is rotatably connected to the guide wheel 8. Two electric actuators 55 are connected to the tube 6. The output shaft of the electric actuator 55 is slidably connected to the tube 6. The end of the output shaft placed inside the tube 6 is inserted into the insertion hole 56 of the rod 7.

[0019] The principle behind the above scheme is as follows: The rotary clamp 2 is used to fix the shaft to be processed. The device has two sets of guide wheels 8, each set containing two guide wheels. Before clamping the shaft part into the device, the shaft part first contacts the guide wheels 8. Simultaneously, the output shaft of the electric actuator 55 is pulled out from the insertion hole 56 to release the locking state of the insertion tube 6 and the insertion rod 7. The two insertion rods 7 in the same insertion tube 6 and their respective connected guide wheels 8 move in opposite directions, and the spring 9 is stretched to cushion the surface of the shaft part. When adjusting the axis of the shaft part relative to the rotary clamp... After the two concentric parts are aligned, the shaft parts move upward a certain distance. Under the action of the spring 9, the reset insert rod 7 drives the guide wheel 8 connected to it to reset. The output of the electric push rod 55 is inserted into the insertion hole 56 to restore the locking state of the insert tube 6 and the insert rod 7. At this time, the guide wheel 8 guides and supports the shaft parts during processing. During processing, the tool 3 on the moving mechanism 4 can be different tool heads to perform external turning, milling, drilling, grooving and other work, and finally complete the multi-station processing of the shaft parts.

[0020] The beneficial effects of the above scheme are as follows: The device is equipped with a guide wheel 8 that is rotatably connected to the insertion rod 7. The insertion rod 7 is slidably connected to the insertion tube 6. The insertion tube 6 and the insertion rod 7 are connected by a spring 9, which can buffer the surface of the shaft parts before clamping and avoid damage to the parts and a decrease in machining accuracy. The buffer function of guide wheel 8 can reduce the accuracy requirements of the tool for moving shaft parts, thereby reducing the cost of the supporting facilities used. The guide wheel 8 not only buffers the parts, but also supports and guides the rotating shaft parts during machining, further ensuring the stability of the parts within the device and thus ensuring machining accuracy. The electric actuator 55 can unlock or lock the insert rod 7 inside the insert tube 6. Therefore, when it is necessary to buffer the shaft parts, it is only necessary to pull the output shaft out of the insert hole 56. When it is necessary to use the guide wheel 8 to guide and support the shaft parts, it is only necessary to insert the output shaft back into the insert hole 56. The guide wheel 8 can switch between two working states. When the guide wheel 8 is unlocked, it can buffer the shaft parts through the spring 9. When the guide wheel 8 is locked, it can provide rigid support for the shaft parts.

[0021] Example 2: Reference Figures 1-14 The moving mechanism 4 includes a motor 11, a screw 12, and a slide rail 13. The output end of the motor 11 on the base 1 is connected to the screw 12. The screw 12 is threadedly connected to the top of the cutter 3 away from the base 1. The cutter 3 is slidably connected to the slide rail 13 on the base 1.

[0022] The principle behind the above scheme is as follows: During machining, the motor 11 is started, and the output end of the motor 11 drives the screw 12 to rotate. The tool 3, which is threadedly connected to the screw 12, moves stably and accurately along the preset path of the slide rail 13 under the guidance of the slide rail 13, thereby controlling the cutting depth, feed rate or switching machining positions to realize multi-station machining of shaft parts.

[0023] The beneficial effects of the above scheme are as follows: The moving mechanism 4, which works in conjunction with the screw 12 and the slide rail 13, enables the tool 3 to achieve high-precision and high-stability linear feed motion, ensuring the accuracy and surface quality of the cutting process, simplifying the control logic, and improving the reliability and automation level of the device.

[0024] Example 3: Reference Figures 1-14 The base 1 has a debris collection port 17, and a collection box is installed inside the debris collection port 17. The top opening of the collection box faces the output end of the tool 3.

[0025] The principle behind the above scheme is as follows: During the cutting process, the metal chips generated fall or are guided to the chip collection port 17 on the base 1 under the action of gravity and coolant or auxiliary airflow, and fall into the collection box installed therein. The collection box can be removed from the chip collection port 17 to clean up the chips and collect the coolant.

[0026] The beneficial effects of the above scheme are as follows: By setting up the debris recovery port 17 and the collection box, the metal debris and coolant generated during processing can be collected in a centralized manner, which helps to keep the working area clean, prevent debris accumulation from affecting equipment accuracy, personnel safety or causing secondary pollution, and improves the environmental friendliness and maintenance convenience of the device.

[0027] Example 4: Reference Figures 1-14 The second moving mechanism 5 includes: a screw block 14, a twin screw 15, and a second motor 16. The bottoms of the two insertion tubes 6 are respectively connected to a screw block 14. The screw block 14 is slidably connected to the base 1. The screw block 14 is threadedly connected to the twin screw 15. The twin screw 15 is connected to the output end of the second motor 16 on the base 1.

[0028] The principle behind the above scheme is as follows: When it is necessary to adjust the spacing between the two guide wheels 8 according to the length of the shaft parts or the support position requirements, start the motor 16, and its output end drives the double screw 15 to rotate. Due to the specific thread design of the double screw 15, the two screw blocks 14 that are threaded to it can move synchronously towards or away from each other, thereby driving the tube 6 and guide wheel 8 assembly connected to it to slide precisely along the slide rail or guide structure on the base 1 to achieve automatic adjustment of the spacing.

[0029] The beneficial effects of the above scheme are as follows: The moving mechanism 25 driven by the twin screw 15 achieves synchronous, symmetrical, and precise adjustment of the spacing between the two sets of guide wheels 8 support components, ensuring the balanced distribution of the auxiliary support force on the shaft parts.

[0030] Example 5: Reference Figures 1-14 The guide wheel 8 has an internal mounting cavity 18, and a tube 19 is connected inside the mounting cavity 18. The tube 19 is rotatably connected to the side wall outside the mounting cavity 18 and the insertion rod 7. Multiple sliding grooves 20 equidistantly opened on the side wall of the guide wheel 8 are all connected to the mounting cavity 18. A cleaning plate 21 is slidably connected in the sliding groove 20. The top of the cleaning plate 21 is coplanar with the side wall of the guide wheel 8. The inner wall of the mounting cavity 18 is connected to the ends of multiple tension springs 22. The other end of the tension springs 22 is connected to the connecting block 23 on the side wall of the cleaning plate 21. The connecting block 23 is placed inside the mounting cavity 18. The side wall of the cleaning plate 21 has an end of an exhaust hole 24. The exhaust hole 24 is placed inside the mounting cavity 18. The other end of the exhaust hole 24 is opened at the bottom of the cleaning plate 21. The inner wall of the other end of the exhaust hole 24 is slidably sealed to the top end of the air guide tube 25. The bottom end of the air guide tube 25 is connected to the inner wall of the tube 19. A locking member 26 is connected to the cleaning plate 21.

[0031] The principles and beneficial effects of the above scheme are as follows: When the guide wheel 8 carries the shaft part, under the elastic force of the tension spring 22 and the locking of the locking member 26, the cleaning plate 21 remains stationary in the slide groove 20 and will not extend out of the surface of the guide wheel 8 due to the centrifugal force. Its top is flush with the side wall of the guide wheel 8 and does not affect the normal rolling of the guide wheel 8. When the guide wheel 8 contacts the surface of the shaft part, the shaft part will not collide with the cleaning plate 21. At this time, the locking member 26 remains locked. When the processing is completed and the debris on the surface of the guide wheel 8 needs to be cleaned, airflow is introduced into the tube 19, the locking part 26 is opened, and the airflow can enter the exhaust hole 24 through the air guide pipe 25 and be ejected from the end of the exhaust hole 24. The ejected gas is directed towards the side wall of the guide wheel 8 to blow away the debris or oil stains on it. At the same time, the cleaning plate 21 extends out of the guide wheel 8, and the airflow flows between two adjacent cleaning plates 21. The airflow further flows between the two cleaning plates 21 to assist in cleaning the surface of the guide wheel 8, blowing away the oil stains, debris, etc. in this area. The cleaning plate 21 itself can also scrape the shaft surface during sliding, playing an auxiliary cleaning role. After cleaning is completed, the airflow supply to the tube 19 is stopped. The removed debris will not cause friction with the surface of the shaft parts, avoiding scratches or indentations on the surface of the shaft parts; at the same time, it will prevent debris from interfering with the smooth rotation of the guide wheel, causing vibration of the support point, and affecting the cutting stability; furthermore, it will not cause debris accumulation to change the actual size or position of the guide wheel, causing the support axis of the shaft parts to shift, thereby reducing the machining dimensional accuracy and surface quality. After the surface of the guide wheel 8 is cleaned, debris or oil stains are removed. Therefore, when placing shaft parts on it, it can further prevent the accumulation or sharp debris on the guide wheel 8 from causing damage to the shaft parts during placement. It can also prevent the shaft parts from slipping relative to the guide wheel 8 when placed, further ensuring the buffering effect of the guide wheel 8 during use.

[0032] Example 6: Reference Figures 1-13 The locking component 26 includes: a baffle tube 27, a second spring 28, a slot 29, a connecting rod 30, a plug 31, and a socket 32. The baffle tube 27 is slidably connected inside the tube body 19. The inner wall of the baffle tube 27 is connected to the inner wall of the tube body 19 through the second spring 28. The top surface of the baffle tube 27 is set facing the air inlet of the tube body 19. Multiple slots 29 are opened through the side wall of the tube body 19. The tube body 19 seals against the slots 29. The bottom ends of multiple connecting rods 30 are connected to the side wall of the baffle tube 27. The plug 31 on the top side wall of the connecting rod 30 is inserted into the socket 32. The plug 31 is set facing the air inlet of the tube body 19. The socket 32 ​​is opened at the bottom of the cleaning plate 21.

[0033] The inner wall of the tube body 19 is connected to the ends of multiple auxiliary tube bodies 50. The other end of the auxiliary tube body 50 is set towards the inclined surface 51 at the bottom of the cleaning plate 21. The inclined surface 51 is set towards the insertion rod 7. The fixing ring 52 inside the auxiliary tube body 50 is connected to the bottom end of the unlocking spring 53. The top end of the unlocking spring 53 is connected to the bottom end of the unlocking post 54. The unlocking post 54 and the auxiliary tube body 50 are in sliding sealing cooperation. The top end of the unlocking post 54 is set towards the inclined surface 51.

[0034] The principles and beneficial effects of the above scheme are as follows: When the cleaning plate 21 is unlocked, the baffle 27 moves away from the insertion rod 7 under the action of airflow, and at the same time compresses the second spring 28. The connecting rod 30 in the slot 29 moves synchronously. At this time, the connecting rod 30 drives the plug 31 to disengage from the socket 32. Meanwhile, the airflow in the auxiliary tube 50 drives the unlocking post 54 to move upward. At this time, the unlocking spring 53 is stretched. The upwardly moving unlocking post 54 applies an upward force to the inclined surface 51 at the bottom of the cleaning plate 21, thereby unlocking the cleaning plate 21. After the airflow supply to the tube 19 ends, the unlocking spring 53 shortens and resets, the unlocking post 54 resets, and the second spring 28 extends and resets. Under the elastic force of the reset tension spring 22, the cleaning plate 21 moves downward, and the plug 31 locks again from the socket 32. This realizes the automatic locking of the components in the mechanism, avoids the complexity of manual operation, and further improves the automation level of the device during use.

[0035] Example 7: Reference Figures 1-13 The air inlet of the pipe body 19 is rotatably and sealed to the end of the adapter pipe 33, the adapter pipe 33 is fixedly connected to the insertion rod 7, and the other end of the adapter pipe 33 is connected to the output end of the air pump.

[0036] The two inner walls of the adapter pipe 33 are each connected to the end of a second pipe body 34. The other end of the inner wall of the second pipe body 34 is slidably sealed to the end of a telescopic pipe 35. The mounting ring on the side wall of the telescopic pipe 35 is connected to the end of a third spring 36. The other end of the third spring 36 is connected to the other end of the second pipe body 34.

[0037] The top of the longitudinal tube 37 is connected to the inner wall of the other end of the telescopic tube 35. The bottom of the longitudinal tube 37 away from the telescopic tube 35 is rotatably connected to the inner wall of the end of the guide tube 38. The guide tube 38 is located on the side of the guide wheel 8. The included angle between the two guide tubes 38 is set at an obtuse angle, which is set towards the guide wheel 8. The end of the wiping tube 39 is rotatably connected to the inner wall of the other end of the guide tube 38. The wiping tube 39 is provided with bristles 40. Multiple inclined cleaning exhaust ports 41 are opened on the side wall of the wiping tube 39.

[0038] The insertion rod 7 is rotatably connected to the ends of two guide rods 42. The other end of the guide rod 42 is slidably connected to the second groove 43 of the guide tube 38. The second groove 43 is arranged parallel to the axis of the guide tube 38. The end of the locking air tube 44 is connected to the inner wall of the longitudinal tube 37. The other end of the locking air tube 44 is arranged on the side wall of the longitudinal tube 37. The inner wall of the locking air tube 44 is provided with an annular groove 45. A piston 46 is slidably connected in the annular groove 45. The end face of the piston 46 away from the inner wall of the longitudinal tube 37 is connected to the end of the fourth spring 47. The other end of the fourth spring 47 is connected to the end of the locking ball 48. The other end of the locking ball 48 is placed outside the longitudinal tube 37 and is positioned towards the guide wheel 8. The guide tube 38 is connected to a groove 49. The locking air tube 44 is arranged between the guide wheel 8 and the groove 49 for engaging with the locking ball 48.

[0039] The principles and beneficial effects of the above scheme are as follows: When the tube body 19 is ventilated, airflow flows synchronously within the transfer tube 33. A portion of the airflow enters the tube body 2 34. Since the inner diameter of the telescopic tube 35 is smaller than the inner diameter of the tube body 2 34, the inner diameter of the longitudinal tube 37 is smaller than the inner diameter of the telescopic tube 35, and the inner diameter of the wiping tube 39 is smaller than the inner diameter of the guide tube 38, after inflation, the end face of the telescopic tube 35 is pushed out by the air pressure while still allowing airflow to pass through. The spring 36 is stretched. Under the sliding cooperation of the guide rod 42 and the slide groove 2 43, the guide tube 38 drives the wiping tube 39 to rotate in the direction of the guide wheel 8. When the bristles on the wiping tube 39... 40 contacts the side wall of the guide wheel. At this time, in order to provide sufficient friction, the part of the brush 40 that contacts the guide wheel 8 will be bent. The airflow discharged from the inclined cleaning exhaust port 41 can drive the wiping tube 39 to rotate. Since the cleaning exhaust ports 41 on the two wiping tubes 39 are arranged in opposite directions, the rotation of the brush bristles 40 can drive the guide wheel 8 that it rubs against to rotate, and assist in cleaning the debris on the guide wheel 8. When the cleaning of the guide wheel 8 is finished, the mechanism resets, the length of the spring 36 shortens, the telescopic tube 35 retracts into the tube body 2 34, and the guide tube 38 rotates in the opposite direction to reset. To ensure the stability of the wiping tube 39 after rotation, when there is airflow in the longitudinal tube 37, the air pressure in the locking air tube 44 increases, and the piston 46 moves away from the inner wall of the longitudinal tube 37. At the same time, the piston 46 is limited by the annular groove 45, and the spring 47 drives the locking ball 48 to move. The rotating guide tube 38 drives the groove 49 to move towards the locking ball 48 until the groove 49 and the locking ball 48 are engaged. At this time, the spring 47 is first compressed and then extended, thereby fixing the guide tube 38. After the airflow supply ends, the piston 46 loses the outward pressure, and the locking ball 48 is pressured by the groove 49 and moves into the interior of the longitudinal tube 37. The locking of the longitudinal tube 37 ends and the guide tube 38 resets.
