Description

Technical Field

[0001] This invention belongs to the field of turning, specifically a device for machining the outer diameter of mechanical parts. Background Technology

[0002] When processing and producing mechanical parts made of rod-shaped materials, it is necessary to turn the outer circle of the workpiece to remove excess material from the outside of the workpiece. The usual method is to use an automatic gripper to center and clamp the end of the rod-shaped workpiece, and then the other end is positioned by the tailstock mechanism, which drives the workpiece to rotate. The tool is then used to complete the turning of the outer circle of the mechanical part.

[0003] A patent document with announcement number CN220880562U discloses an external cylindrical lathe for valve stem production, including a base, a support mechanism, and a fixing device. The support mechanism includes a sliding plate slidably connected to the upper surface of the base along its length direction. One end of the raw material is fixed by the fixing device. Then, the position of the support mechanism can be adjusted according to the length of the raw material. After the position of the support mechanism is adjusted, the distance between the two support rollers in the support mechanism can be adjusted according to the diameter of the raw material to adapt to the raw material, so that the device can provide good support for the material.

[0004] In traditional technology, after the workpiece is clamped at one end by an automatic gripper, the other end is positioned by a tailstock mechanism. Then, the workpiece is rotated to perform external turning. However, since the end of the workpiece also needs to be externally turned, the structure of the tailstock mechanism that holds the workpiece at one end will be conical. That is, the closer this structure is to the end of the workpiece, the smaller its diameter becomes. This leads to vibration when the workpiece is rotated and turned, as the workpiece is clamped at only one end. The end of the workpiece that is far from the automatic gripper is prone to vibration during turning, which affects the turning quality of the workpiece.

[0005] Therefore, the present invention provides a machining apparatus for the outer diameter of mechanical parts to solve the problems mentioned in the background art. Summary of the Invention

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a machining device for machining the outer diameter of mechanical parts, including a machine tool and an automatic gripper mounted at one end of the machine tool. A movable positioning component is movably mounted at the other end of the machine tool. A valve stem mechanical component is positioned between the automatic gripper and the movable positioning component. A sliding mechanism is also slidably mounted on the machine tool. The sliding mechanism is located between the automatic gripper and the movable positioning component. A machining table and a turning tool are slidably mounted on one side above the sliding mechanism. A shock-absorbing workpiece is mounted on the other side above the sliding mechanism. The valve stem mechanical component is located between the turning tool and the shock-absorbing workpiece. The shock-absorbing component includes a fixed frame fixedly installed above the sliding mechanism and an elastic shock-absorbing mechanism slidably installed inside the fixed frame. A pushing mechanism is installed inside the fixed frame, and one end of the pushing mechanism is connected to the side of the elastic shock-absorbing mechanism. The elastic shock-absorbing mechanism includes a displacement frame and two guide rails fixedly installed on one side of the displacement frame. A frame-shaped component is slidably installed on the outer side of the two guide rails. The frame-shaped component moves horizontally through a sliding connection with the two guide rails. A roller component is rotatably installed inside the frame-shaped component. An elastic telescopic component is installed on one side of the roller component. One end of the elastic telescopic component is fixedly connected to the side of the displacement frame. Two automatic oil supply components are also symmetrically distributed inside the fixed frame. The two automatic oil supply components are used to lubricate the roller component.

[0007] Preferably, the roller component includes a shock-absorbing roller rotatably mounted inside the center of the frame member, the diameter of the shock-absorbing roller being larger than the width of the frame member, and the roller component also includes a U-shaped block fixedly mounted on one side of the center of the frame member, one end of the elastic telescopic member being connected to the side of the U-shaped block.

[0008] Preferably, the upper and lower positions inside the fixed frame are provided with limit grooves, and the upper and lower ends of the displacement frame are slidably installed inside the corresponding limit grooves.

[0009] Preferably, elastic cover strips are installed on both sides of the structure at the upper and lower ends of the displacement frame that are inside the corresponding limiting groove, and the other end of each elastic cover strip is connected to the inner wall of the corresponding limiting groove.

[0010] Preferably, a ring spring is installed inside the limiting groove, and a pressure sensor is installed at the end of the limiting groove. One end of the ring spring is connected to the corresponding end of the displacement frame, and the other end of the ring spring is connected to the pressure sensor.

[0011] Preferably, the frame member has a rotating groove inside and an annular cavity surrounding the outside of the rotating groove. The diameter of the annular cavity is larger than the diameter of the rotating groove, and the thickness of the annular cavity is smaller than the thickness of the rotating groove. The rotating groove is used for the rotation of the shafts on both sides of the center of the shock-absorbing roller. The frame member also has an L-shaped oil groove inside, which is connected to the annular cavity.

[0012] Preferably, the frame member also has an outwardly facing annular groove, and a silicone check valve is installed inside the annular groove. The silicone check valve is a silicone diaphragm, and the silicone diaphragm has a cross or Y-shaped slit cut on it.

[0013] Preferably, the automatic oil supply component includes a fixing bar and a transmission block movably installed on one side thereon. An oil supply nozzle is installed on one side of the transmission block.

[0015] Preferably, a pressure sensor two is installed inside the upper end of the fixing bar, and one end of the annular spring two is connected to the pressure sensor two.

[0016] The beneficial effects of this invention are as follows: 1. The present invention discloses a machining device for the outer diameter of mechanical parts. An automatic gripper drives the workpiece to rotate, and the machining table and turning tool move towards the workpiece until the turning tool contacts the outer side of the workpiece, thus achieving turning. The extension of the pushing mechanism drives the elastic anti-vibration mechanism to move inside the fixed frame until the roller component contacts the outer side of the workpiece. The distance between the roller component and the moving positioning component is greater than the distance between the turning tool and the moving positioning component. The roller component has a rolling structure that rotates with the workpiece and forms a positioning and pressing effect with the turning tool. Therefore, it can avoid severe vibration when a workpiece clamped at one end is turned.

[0017] 2. The mechanical part external cylindrical machining device of the present invention includes an elastic telescopic component inside the elastic anti-vibration mechanism. When the roller component contacts the outer side of the workpiece, if the pushing mechanism continues to extend, the frame component and the roller component will be horizontally displaced in the direction of the pushing mechanism through the two guide rails. At this time, the elastic telescopic component is compressed. The reverse elastic force of the compressed elastic telescopic component allows the roller component to press against the outer side of the workpiece with a certain pressure, thereby providing a better shock absorption effect and reducing tool deflection. After the turning process is completed, the pushing mechanism will retract and drive the elastic anti-vibration mechanism to return to its original position. At this time, the frame component will contact the automatic oil supply component, which can supply oil to the internal rolling structure of the roller component, extending the service life of the workpiece.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: As Figures 1-3 As shown, an embodiment of the present invention provides a machining device for machining the outer diameter of a mechanical part, including a machine tool 1 and an automatic gripper 2 installed at one end of the machine tool 1. A movable positioning component 11 is movably installed at the other end of the machine tool 1. A valve stem mechanical part is positioned between the automatic gripper 2 and the movable positioning component 11. A sliding mechanism 12 is also slidably installed on the machine tool 1. The sliding mechanism 12 is positioned between the automatic gripper 2 and the movable positioning component 11. A machining table 121 and a turning tool 122 are slidably installed on one side above the sliding mechanism 12. A shock-absorbing workpiece 3 is installed on the other side above the sliding mechanism 12. The valve stem mechanical part is positioned between the turning tool 122 and the shock-absorbing workpiece 3. The shock-absorbing component 3 includes a fixed frame 4 fixedly installed above the sliding mechanism 12 and an elastic shock-absorbing mechanism 6 slidably installed inside the fixed frame 4. A pushing mechanism 5 is installed inside the fixed frame 4, and one end of the pushing mechanism 5 is connected to the side of the elastic shock-absorbing mechanism 6. The elastic shock-absorbing mechanism 6 includes a displacement frame 61 and two guide rails 63 fixedly installed on one side of the displacement frame 61. A frame-shaped component 64 is slidably installed on the outside of the two guide rails 63. The frame-shaped component 64 moves horizontally through the sliding connection with the two guide rails 63. A roller component 65 is rotatably installed inside the frame-shaped component 64. An elastic telescopic component 62 is installed on one side of the roller component 65. One end of the elastic telescopic component 62 is fixedly connected to the side of the displacement frame 61. Two automatic oil supply components 7 are also symmetrically distributed inside the fixed frame 4. The two automatic oil supply components 7 are used to lubricate the roller component 65.

[0023] Specifically, after one end of the rod-shaped mechanical part is clamped by the automatic gripper 2, the electric drive causes the movable positioning component 11 to move until its end presses against the other end of the rod workpiece, thereby achieving workpiece positioning. Since the end of the workpiece near the movable positioning component 11 also needs to be turned, the structure of the movable positioning component 11 in contact with the workpiece end is conical, that is, the diameter of this structure becomes smaller the closer it is to the workpiece. At this time, the automatic gripper 2 drives the workpiece to rotate, and the machining table 121 and the turning tool 122 move towards the workpiece until the turning tool 122 contacts the outer side of the workpiece to achieve turning. However, since the workpiece is only clamped at one end and the other end is only for positioning, the outer circle of the workpiece will vibrate during turning, which is not conducive to the machining quality of the workpiece. At this time, the extension of the pushing mechanism 5 can drive the elastic anti-vibration mechanism 6 to move inside the fixed frame 4 until the roller component 65 contacts the outer side of the workpiece. The distance between the roller component 65 and the movable positioning component 11 is greater than that of the turning tool. The distance between the 122 and the movable positioning member 11 is such that the roller member 65 has a rolling structure inside. This structure rotates with the workpiece and forms a positioning and pressing effect with the turning tool 122. Therefore, it can avoid the phenomenon of severe vibration when the workpiece clamped at one end is turned on the outer diameter. The elastic anti-vibration mechanism 6 also has an elastic telescopic member 62 inside. When the roller member 65 contacts the outer side of the workpiece, if the pushing mechanism 5 continues to extend, it will cause the frame member 64 and the roller member 65 to be pushed by the two guide rails 63. The moving mechanism 5 moves horizontally, at which time the elastic telescopic member 62 is compressed. The reverse elastic force of the compressed elastic telescopic member 62 allows the roller component 65 to press against the outside of the workpiece with a certain pressure, thereby providing a better shock absorption effect and reducing tool deflection. After the turning process is completed, the pushing mechanism 5 will retract and drive the elastic anti-vibration mechanism 6 to return to its original position. At this time, the frame component 64 will contact the automatic oil supply component 7. The automatic oil supply component 7 can supply oil to the internal rolling structure of the roller component 65, extending the service life of the workpiece.

[0024] like Figures 4-5 As shown, the roller component 65 includes a shock-absorbing roller 651 rotatably installed at the center position inside the frame component 64. The diameter of the shock-absorbing roller 651 is larger than the width of the frame component 64. The roller component 65 also includes a U-shaped block 652 fixedly installed on one side of the center position of the frame component 64. One end of the elastic telescopic member 62 is connected to the side of the U-shaped block 652.

[0025] Limiting grooves 41 are provided at both the upper and lower positions inside the fixed frame 4, and the upper and lower ends of the displacement frame 61 are slidably installed inside the corresponding limiting grooves 41.

[0026] The upper and lower ends of the displacement frame 61 are equipped with elastic cover strips 42 on both sides of the structure inside the corresponding limiting grooves 41. The other end of the elastic cover strips 42 is connected to the inner wall of the corresponding limiting grooves 41.

[0027] A ring spring 43 is installed inside the limiting groove 41, and a pressure sensor 44 is installed at the end of the limiting groove 41. One end of the ring spring 43 is connected to the corresponding end of the displacement frame 61, and the other end of the ring spring 43 is connected to the pressure sensor 44.

[0028] Specifically, the anti-vibration roller 651 can move until it contacts the outside of the workpiece. When the workpiece rotates, the anti-vibration roller 651 is driven to rotate. The two sides of the anti-vibration roller 651 are rotatably installed inside the frame member 64 via shafts. When the automatic oil supply component 7 performs oil supply work, its liquid lubricating oil will be supplied to the rotational connection between the two shafts on the outside of the anti-vibration roller 651 and the frame member 64. When the push mechanism 5 extends and drives the elastic anti-vibration mechanism 6 to move, the upper and lower ends of the displacement frame 61 will move inside the corresponding limiting groove 41. At this time, the two elastic covering strips 42 inside the limiting groove 41 will extend and retract to cover the limiting groove 41. When the elastic anti-vibration mechanism 6 moves toward the workpiece, the upper and lower ends of the elastic anti-vibration mechanism 6 will squeeze the two corresponding ring springs 43. This squeezing will cause the ring springs 43 to compress, and the pressure value can be displayed on the two pressure sensors 44. The moving distance of the elastic anti-vibration mechanism 6 can be confirmed by the pressure value, and it can be used to adapt to the turning of the outer diameter of mechanical parts bar stock of different diameters.

[0029] Example 2: Figures 6-8 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the frame member 64 has a rotating groove 645 and an annular cavity 644 surrounding the outside of the rotating groove 645. The diameter of the annular cavity 644 is larger than the diameter of the rotating groove 645, and the thickness of the annular cavity 644 is smaller than the thickness of the rotating groove 645. The rotating groove 645 is used for the rotation of the shafts on both sides of the center of the shock-absorbing roller 651. The frame member 64 also has an L-shaped oil groove 643 inside, which is connected to the annular cavity 644.

[0030] The frame component 64 also has an outwardly opening an annular groove 642, and a silicone check valve 641 is installed inside the annular groove 642. The silicone check valve 641 is a silicone diaphragm, and the silicone diaphragm has cross or Y-shaped slits cut on it.

[0031] The automatic oil supply component 7 includes a fixing bar 71 and a transmission block 72 movably installed on one side of it. An oil supply nozzle 76 is installed on one side of the transmission block 72. The diameter of the end of the oil supply nozzle 76 facing the frame member 64 matches the diameter of the L-shaped oil trough 643, and both are at the same horizontal height.

[0032] A ring spring 73, a flexible oil pipe 74, and a telescopic component 75 are installed between the fixed bar 71 and the transmission block 72. The ring spring 73, the flexible oil pipe 74, and the telescopic component 75 are at different horizontal heights.

[0033] Pressure sensor 2 711 is installed inside the upper end of the fixing bar 71, and one end of the annular spring 2 73 is connected to pressure sensor 2 711.

[0034] Specifically, when the pushing mechanism 5 extends, the anti-vibration roller 651 will abut against the outside of the workpiece to achieve a vibration reduction effect. At this time, the anti-vibration roller 651 will rotate with the workpiece through the rotating connection of the shafts on both sides inside the rotating groove 645. When the outer circle machining of the workpiece is completed, the pushing mechanism 5 will retract, driving the elastic anti-vibration mechanism 6 to move inward toward the fixed frame 4 until the limit position. At this time, the small diameter end of the oil nozzle 76 will enter the limit position of the horizontal position of the L-shaped oil groove 643 through the silicone check valve 641. Then, the liquid lubricating oil is fed into the oil nozzle 76 through the internal pipe of the fixed bar 71, the soft oil delivery pipe 74, and the internal pipe of the transmission block 72 in the order of feeding by the external oil pump. At this time, the liquid lubricating oil is injected into the L-shaped oil groove 643 through the oil nozzle 76. The vertical pipe 63 and the annular cavity 644 are filled until both are completely filled. This indicates that the rotation of the anti-vibration roller 651 is in optimal condition. As the anti-vibration roller 651 rotates with the workpiece, its horizontal displacement force is damped by the elastic restoring force of the elastic expansion member 62, ensuring that the anti-vibration roller 651 always presses against the outside of the workpiece. The lubricating oil filled in the annular cavity 644 ensures smooth rotation of the shafts on both sides of the anti-vibration roller 651 within the rotating groove 645, and also counteracts vertical vibration forces, further improving shock resistance and extending the service life of the device. After the vertical pipe 643 and the annular cavity 644 are completely filled, if the oil inlet 76 continues to inject oil, it will cause lubricating oil to enter... Upon reaching the horizontal pipe of the L-shaped oil sump 643, due to the installation of the flexible oil delivery pipe 74, the telescopic component 75, and the second annular spring 73, the telescopic component 75 retracts from its naturally extended state, the flexible oil delivery pipe 74 bends from its straight state, and the second annular spring 73 is compressed. Once the second annular spring 73 is compressed, the pressure sensor 711 in contact with it will sense the pressure value. That is, when the transmission block 72 and the oil nozzle 76 move a certain distance toward the fixed bar 71, if the pressure value sensed by the pressure sensor 711 is too high, it indicates that the liquid lubricating oil has not only filled the vertical pipe of the L-shaped oil sump 643 and the interior of the annular cavity 644, but has also entered the horizontal pipe of the L-shaped oil sump 643. At this point, the operation of the external oil pump can be stopped, and oil delivery can cease. The nozzle 76 injects oil, completing the automatic oil injection process. When the pushing mechanism 5 extends and moves the elastic shock-absorbing mechanism 6, the oil nozzle 76 disengages from the silicone one-way valve 641. The silicone one-way valve 641 prevents lubricating oil from leaking out of the L-shaped oil groove 643 and the annular cavity 644. The principle of the silicone one-way valve 641 is similar to the one-way passage principle of a heart valve. The elastic shock-absorbing mechanism 6 moves by the contraction of the pushing mechanism 5, allowing the automatic oil supply component 7 to enter the elastic shock-absorbing mechanism 6 for oil injection. After one oil injection is completed, the contraction of the pushing mechanism 5 allows the elastic shock-absorbing mechanism 6 to move as usual, meaning the shock-absorbing roller 651 no longer presses against the outside of the workpiece, but it prevents the automatic oil supply component 7 from entering the elastic shock-absorbing mechanism 6 for oil injection.Automated oil injection is achieved by controlling the movement distance of the elastic shock-absorbing mechanism 6.

[0035] Working principle: After one end of the rod-shaped mechanical part is clamped by the automatic gripper 2, the electric drive causes the movable positioning component 11 to move until its end presses against the other end of the workpiece, thereby achieving workpiece positioning. Since the end of the workpiece near the movable positioning component 11 also needs to be turned, the structure of the movable positioning component 11 in contact with the workpiece end is conical, that is, the diameter of this structure becomes smaller the closer it is to the workpiece. At this time, the automatic gripper 2 drives the workpiece to rotate, and the machining table 121 and the turning tool 122 move towards the workpiece until the turning tool 122 contacts the outer side of the workpiece, realizing the turning process. However, since the workpiece is only clamped at one end and the other end is only for abutment positioning, the outer circle of the workpiece is turned... Vibration occurs during machining, which is detrimental to the machining quality of the workpiece. In this case, the extension of the pushing mechanism 5 drives the elastic anti-vibration mechanism 6 to move inside the fixed frame 4 until the roller component 65 contacts the outer side of the workpiece. The distance between the roller component 65 and the moving positioning element 11 is greater than the distance between the turning tool 122 and the moving positioning element 11. The roller component 65 has a rolling structure that rotates with the workpiece and forms a positioning and pressing effect with the turning tool 122. Therefore, it can prevent severe vibration when a workpiece clamped at one end is turned on its outer diameter. An elastic telescopic element 62 is also provided inside the elastic anti-vibration mechanism 6. When the roller component 65 contacts the outer side of the workpiece, if the pushing mechanism 5 continues to extend, it will cause… The frame component 64 and the roller component 65 are horizontally displaced towards the pushing mechanism 5 via two guide rails 63. During this time, the elastic telescopic component 62 is compressed. The reverse elastic force of the compressed elastic telescopic component 62 allows the roller component 65 to press against the outside of the workpiece with a certain pressure, thus providing better shock absorption and reducing tool deflection. After the turning process is completed, the pushing mechanism 5 retracts, causing the elastic anti-vibration mechanism 6 to return to its original position. At this time, the frame component 64 will contact the automatic oil supply component 7, which can supply oil to the internal rolling structure of the roller component 65, extending the workpiece's service life. When the pushing mechanism 5 extends, the anti-vibration roller 651 will press against the outside of the workpiece to achieve a shock absorption effect. At this time, the anti-vibration roller 651 will rotate via the shafts on both sides. The rotating connection inside groove 645 follows the workpiece's rotation. When the outer diameter of the workpiece is machined, the pushing mechanism 5 retracts, causing the elastic anti-vibration mechanism 6 to move towards the inside of the fixed frame 4 until it reaches its limit position. At this time, the small-diameter end of the oil nozzle 76 enters the limit position of the horizontal position of the L-shaped oil groove 643 through the silicone check valve 641. Subsequently, liquid lubricating oil is fed into the oil nozzle 76 through the internal pipes of the fixed bar 71, the soft oil supply pipe 74, and the internal pipes of the transmission block 72 via an external oil pump. The liquid lubricating oil is then injected into the vertical pipe of the L-shaped oil groove 643 and the annular cavity 644 through the oil nozzle 76 until both cavities are filled. This indicates that the rotation of the anti-vibration roller 651 is in optimal condition.As the anti-vibration roller 651 rotates with the workpiece, its horizontal displacement force is damped by the elastic restoring force of the elastic expansion member 62, ensuring that the anti-vibration roller 651 always presses against the outside of the workpiece. Meanwhile, the lubricating oil stored inside the annular cavity 644 ensures smooth rotation of the shafts on both sides of the anti-vibration roller 651 within the rotating groove 645, and also counteracts vertical vibration forces, further enhancing its anti-vibration capability and extending the service life of the device. When the vertical pipe of the L-shaped oil groove 643 and the interior of the annular cavity 644 are both filled, if the oil nozzle... 76. Continuing to inject oil will cause lubricating oil to enter the transverse pipe of the L-shaped oil trough 643. At this time, due to the setting of the flexible oil delivery pipe 74, the telescopic component 75, and the second annular spring 73, the telescopic component 75 will retract from its naturally extended state, the flexible oil delivery pipe 74 will bend from its straight state, and the second annular spring 73 will be compressed. Once the second annular spring 73 is compressed, the pressure sensor 711 in contact with it will sense the pressure value. That is, when the transmission block 72 and the oil nozzle 76 move a certain distance toward the fixed bar 71, the pressure sensor 711 will detect the pressure value. When the pressure reading is too high, it indicates that the liquid lubricating oil has not only filled the vertical pipe of the L-shaped oil sump 643 and the interior of the annular cavity 644, but has also entered the horizontal pipe of the L-shaped oil sump 643. At this point, the operation of the external oil pump can be stopped, and the oil inlet 76 can no longer inject oil, thus completing the automatic oil injection process. When the push mechanism 5 extends and drives the elastic anti-vibration mechanism 6 to move, the oil inlet 76 will disengage from the silicone check valve 641. The silicone check valve 641 prevents the lubricating oil inside the L-shaped oil sump 643 and the annular cavity 644 from leaking out. The principle of valve 641 can be compared with the one-way passage principle of heart valves. The elastic shock-absorbing mechanism 6 moves by the contraction of the pushing mechanism 5, allowing the automatic oil supply component 7 to enter the elastic shock-absorbing mechanism 6 for oil injection. After one oil injection is completed, the contraction of the pushing mechanism 5 allows the elastic shock-absorbing mechanism 6 to move as usual; that is, the shock-absorbing roller 651 no longer presses against the outside of the workpiece, but it prevents the automatic oil supply component 7 from entering the elastic shock-absorbing mechanism 6 for oil injection. Automated oil injection is achieved by controlling the moving distance of the elastic shock-absorbing mechanism 6.
