Description

Technical Field

[0001] The present invention relates to the technical field of manufacturing industrial automatic control system devices, and specifically relates to a water spray pipe driving mechanism for piston pin cutting and processing. Background Art

[0002] A piston pin is a cylindrical pin installed in the piston skirt. Its middle part passes through the small end hole of the connecting rod and is used to connect the piston and the connecting rod. Its function is to transmit the gas force borne by the piston to the connecting rod, or to drive the piston to move together with the small end of the connecting rod. In order to reduce weight, piston pins are generally made of high-quality alloy steel and are made hollow. When processing piston pins, a boring tool is required to cut the surface of the piston pin to ensure that the outer diameter of the piston pin meets the required dimensions; In the prior art, in order to prevent the piston pin from thermal deformation and the tool from excessive wear, when cutting the piston pin, it is generally necessary to use a nozzle to spray coolant onto the piston pin and the tool to achieve an effective cooling effect. For example, a Chinese patent with the publication number CN118617170B discloses a cutting device for piston pin production that is easy to adjust. By arranging the water spray pipe above the processing table, the water outlet of the water spray pipe faces the cutting tool, and the water spray pipe is used to move together with the moving mechanism, which can continuously and stably spray water onto the cutting part, reducing the temperature and friction during the cutting process, and further improving the cutting efficiency and the service life of the cutting tool; Although the above cutting device can achieve the spraying of coolant and the water spray pipe can move synchronously with the tool, the angle of the water spray pipe is fixed, and its water spraying end is always located above the tool, which can only achieve single-point spraying and cannot spray and cool other cutting positions (such as the side and bottom) of the tool, and cannot adjust the angle of the water outlet end of the spray pipe.

Detailed implementation manners

[0028] The principles and features of the present invention will be described below in conjunction with the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0029] The present invention provides the following preferred embodiments: Embodiment 1, as Figures 1 - 10 shown, a water spray pipe driving mechanism for piston pin cutting and processing includes a processing table 11, and also includes a water spray pipe 30, a conveying structure and a swinging structure; A positioning structure and a cutting structure are further provided at the top of the processing table 11; The positioning structure is used to position and fix the piston pin to be processed, and the cutting structure is used to cut the surface of the piston pin to make its size meet the requirements. During cutting, in order to prevent the piston pin from thermal deformation and the cutting tool 25 from excessive wear, the coolant is conveyed to the water spray pipe 30 through the conveying structure, and the water spray pipe 30 sprays the coolant to the cutting area, which has an effective cooling effect on the cutting area, reduces the temperature and friction during cutting. At the same time, when the water spray pipe 30 sprays, the swinging structure can be used to swing the water spray pipe 30 to achieve multi-directional spraying and cooling, increase the coverage area of the coolant, and reduce the temperature of the cutting area; The cutting structure includes a cutting tool 25, a first electric slide table 21 and a second electric slide table 23. The electric slide table mainly consists of a slider, a linear guide rail, a driving unit, etc. The driving unit is used to drive the slider to move to achieve transmission. The electric slide table is mainly used in the field of industrial automation, which is prior art and will not be elaborated here. In this mechanism, the first electric slide table 21 and the second electric slide table 23 are mainly used to drive the cutting tool 25 to move to adjust the position of the cutting tool 25. Specifically, the second electric slide table 23 can drive the cutting tool 25 to move towards the direction of the piston pin, and the first electric slide table 21 can drive the cutting tool 25 to move along the length direction of the piston pin. At the same time, with the rotation of the piston pin, boring of the piston pin is achieved. The positioning structure includes a driving component and a pressing component; The swinging structure includes a supporting component, a rotating component and a transmission component. The supporting component and the rotating component are both installed above the second electric slide table 23. The water spraying pipe 30 is installed above the supporting component, and the transmission component is located on one side of the rotating component; The conveying structure is installed at one end of the water spraying pipe 30; This driving mechanism belongs to the manufacturing technology of industrial automatic control system devices. The driving mechanism of the water spraying pipe plays a key role in the cutting process of the piston pin. Through the automatic control and adjustment of the industrial automatic control system for the operation of this driving structure, during the cutting process of the piston pin, the smooth processing of the piston pin can be guaranteed through the industrial automatic control system.

[0030] As Figures 1 - 10 shown, the first electric slide table 21 is fixed to the top of the processing table 11. Above the first electric slide table 21, there is a first moving plate 22. Specifically, the first moving plate 22 is fixed above the slider of the first electric slide table 21. When the first electric slide table 21 works, it can drive the first moving plate 22 to move along the length direction of the first electric slide table 21. The second electric slide table 23 is fixed to the top of the first moving plate 22. That is, when the first moving plate 22 moves driven by the first electric slide table 21, it can synchronously drive the second electric slide table 23 to move. Above the second electric slide table 23, there is a second moving plate 24. Specifically, the second moving plate 24 is fixed on the slider of the second electric slide table 23. When the second electric slide table 23 works, it can drive the second moving plate 24 to move along the length direction of the second electric slide table 23. The cutting tool 25 is installed above the second moving plate 24. When the second moving plate 24 moves driven by the second electric slide table 23, it can drive the cutting tool 25 to move. The supporting component and the rotating component are both installed above the second moving plate 24.

[0031] As Figures 1 - 10As shown, the support assembly includes an arc-shaped guide rail 26, an arc-shaped plate 28, a mounting block 29, a swing rod 36, a connecting rod 37, a first vertical plate 35 and two mounting rods 27. The arc-shaped guide rail 26 is located outside the tool 25. Both mounting rods 27 are fixed to one side of the arc-shaped guide rail 26. The bottom end of each mounting rod 27 is fixedly connected to the second moving plate 24. The arc-shaped guide rail 26 is supported and installed by the two mounting rods 27. The arc-shaped plate 28 is slidably arranged outside the arc-shaped guide rail 26. The mounting block 29 is fixed to the surface of the arc-shaped plate 28. The water spray pipe 30 is installed on the mounting block 29. The first vertical plate 35 is located on one side of the two mounting rods 27 and is fixed to the top end of the second moving plate 24. One end of the swing rod 36 is fixed with a rotating shaft. The rotating shaft is rotatably arranged on one side of the first vertical plate 35. The other end of the swing rod 36 is connected to one end of the connecting rod 37. The other end of the connecting rod 37 is connected to the surface of the arc-shaped plate 28; When the rotating shaft at the end of the swing rod 36 swings, it can drive the swing rod 36 to swing synchronously. The swing rod 36 can drive the arc-shaped plate 28 to reciprocate above the arc-shaped guide rail 26 through the connecting rod 37, so that the water spray pipe 30 can be driven to reciprocate through the mounting block 29, enabling the water spray pipe 30 to reciprocate in the top, side and bottom directions of the tool 25, thereby realizing water spraying and cooling at the top, side and bottom positions of the boring area, continuously adjusting the water flow direction during boring, ensuring that the coolant can accurately cover the cutting area, avoiding spraying blind spots caused by single-point spraying, thus achieving an effective cooling effect, reducing the temperature and friction during cutting, and further improving the cutting efficiency and the service life of the cutting tool; It should be noted that when the arc-shaped plate 28 moves on the arc-shaped guide rail 26, it does not contact the second moving plate 24. At the same time, when the water spray pipe 30 reciprocates, it does not contact the piston pin.

[0032] As Figures 1 - 10 shown, the rotating assembly includes a first pulley 38, a second pulley 39, a transmission belt 40, a second vertical plate 41, a turntable 42, a plug post 43, a rotating rod 44 and a strip-shaped groove 45. The second vertical plate 41 is fixed to the top end of the second moving plate 24. The turntable 42 is rotatably arranged on one side of the second vertical plate 41. The first pulley 38 is fixed to the rotating shaft at one end of the swing rod 36, that is, the first pulley 38 is fixedly connected to the swing rod 36 through the rotating shaft. The second pulley 39 is located below the first pulley 38 and is rotatably arranged on one side of the first vertical plate 35. The transmission belt 40 is sleeved on the first pulley 38 and the second pulley 39. One end of the rotating rod 44 is fixed to the middle of one side of the second pulley 39. When the rotating rod 44 rotates, it can drive the second pulley 39 to rotate synchronously. The strip-shaped groove 45 is opened on the surface of the rotating rod 44. One end of the plug post 43 is inserted into the strip-shaped groove 45, and the other end of the plug post 43 is fixed to the surface of the turntable 42; When the cutting tool 25 moves along the length direction of the piston pin under the action of the first electric slide table 21, it can drive the rotary table 42 to rotate under the action of the transmission assembly. When the rotary table 42 rotates, the swinging rod 44 can be swung through the cooperation of the insertion post 43 and the strip-shaped groove 45, so as to drive the second pulley 39 to swing reciprocally on the first vertical plate 35. Under the action of the transmission belt 40, when the second pulley 39 swings reciprocally, it can drive the first pulley 38 to swing reciprocally, so as to drive the swinging rod 36 to swing reciprocally, realizing the swinging of the water spray pipe 30; When rotating, the water outlet end of the water spray pipe 30 always aims at the position between the cutting tool 25 and the piston pin, that is, the water outlet end of the water spray pipe 30 always aims at the cutting contact point, which can accurately cool the boring point in multiple directions, ensure that the water flow directly focuses on the cutting point, and reduce water consumption.

[0033] As Figures 1 - 10 shown, the transmission assembly includes a first sprocket 46, a second sprocket 47, a chain 48, a first mounting plate 49, a rotating sleeve rod 50, a second mounting plate 54, a gear 55, a rack 56, a connecting component and two support plates 57. The first mounting plate 49 is fixed to one side of the second moving plate 24. The rotating sleeve rod 50 is rotatably arranged on the first mounting plate 49 through a bearing. The second sprocket 47 is fixed to one end of the rotating sleeve rod 50. The first sprocket 46 is located on the side of the second vertical plate 41 away from the rotary table 42. The first sprocket 46 is coaxially and fixedly connected to the rotary table 42. The chain 48 is sleeved outside the first sprocket 46 and the second sprocket 47. The second mounting plate 54 is fixed to the top of the first moving plate 22. The gear 55 is located on one side of the second mounting plate 54. The rack 56 is located below the gear 55 and meshes with the gear 55. The two support plates 57 are symmetrically fixed to both sides of the rack 56. Each support plate 57 is mounted on the top of the processing table 11. The connecting component is located between the rotating sleeve rod 50 and the gear 55; When boring the piston pin, that is, when the cutting tool 25 cuts along the length direction of the piston pin under the action of the first electric slide table 21, the cutting tool 25 can synchronously drive the first moving plate 22, the second electric slide table 23 and the second moving plate 24 to move, and the first moving plate 22 drives the second mounting plate 54 to move.

[0034] As Figures 1 - 10 shown, the connecting component includes a limiting groove 51, an insertion rod 52 and a limiting strip 53. The insertion rod 52 is slidably inserted into the inside of the rotating sleeve rod 50. The limiting groove 51 is opened on the inner wall of the rotating sleeve rod 50. The limiting strip 53 is fixed to the surface of the insertion rod 52. The limiting strip 53 is slidably arranged inside the limiting groove 51. One end of the insertion rod 52 away from the rotating sleeve rod 50 is rotatably arranged on the second mounting plate 54 through a bearing. The gear 55 is fixed to the end of the insertion rod 52; When the second mounting plate 54 moves, it can drive the insertion rod 52 and the gear 55 fixed to the end of the insertion rod 52 to move. Since the gear 55 meshes with the rack 56, the gear 55 can rotate along its axis when moving, thereby driving the insertion rod 52 to rotate on the second mounting plate 54. When the insertion rod 52 rotates, it can drive the rotating sleeve rod 50 to rotate on the first mounting plate 49 under the cooperation of the limiting groove 51 and the limiting strip 53, thereby driving the second sprocket 47 to rotate. Under the action of the chain 48, when the second sprocket 47 rotates, it can drive the turntable 42 to rotate; Through the arranged transmission assembly, when the cutting tool 25 moves along the piston pin for cutting, it can synchronously drive the rotating assembly to work, so that the water spraying pipe 30 on the supporting assembly can reciprocally swing, that is, when the cutting tool 25 moves, the water spraying pipe 30 can reciprocally swing, realizing multi-directional spraying and cooling of the cutting tool 25, increasing the coverage area of the coolant, and reducing the temperature of the cutting area; It should be noted that when the second electric sliding table 23 works to move the second moving plate 24, the second moving plate 24 can drive the first mounting plate 49 to move. The first mounting plate 49 drives the rotating sleeve rod 50 to slide above the insertion rod 52, so that a connection relationship can be maintained between the rotating sleeve rod 50 and the insertion rod 52, that is, when the second moving plate 24 slides on the second electric sliding table 23, the insertion rod 52 can drive the rotating sleeve rod 50 to rotate when rotating.

Specifically, the storage device includes a pump body and a storage tank. One end of the conveying pipe 33 is connected to the output end of the pump body, and the input end of the pump body is connected to the inner cavity of the storage tank. During boring, the controller controls the pump body to work, conveys the coolant inside the storage tank through the pump body to the conveying pipe 33, and then conveys the coolant to the water spraying pipe 30 through the hose 32 and the connecting pipe 31, and sprays the coolant through the water spraying pipe 30 to achieve an effective cooling effect.

[0036] As Figures 1 - 10As shown, the driving component includes a side plate 12, a motor 13, and an electric gripper 14. The side plate 12 is fixed to one side of the top of the processing table 11.

The output end of the motor 13 passes through the side plate 12 and is fixedly connected to the electric gripper 14. The electric gripper 14 is a prior art device used to clamp the end of the piston pin to achieve the positioning and support of the piston pin. During boring, the controller controls the motor 13 to operate. The motor 13 can drive the electric gripper 14 to rotate on one side of the side plate 12, thereby driving the piston pin to rotate. At the same time, in cooperation with the tool 25, the processing of the piston pin can be achieved. As Figures 1 - 10 shown, the pressing component includes a pressing block 15, a moving frame 16, and a moving member. The moving frame 16 is slidably arranged on the top of the processing table 11. The pressing block 15 is rotatably arranged on one side of the moving frame 16 through a bearing. The moving member is located between the processing table 11 and the moving frame 16. After the electric gripper 14 clamps one end of the piston pin, to ensure the positioning effect of the piston pin, the moving member is used to drive the moving frame 16 to move. The moving frame 16 can drive the pressing block 15 to move, so that the pressing block 15 can press the other end of the piston pin, improving the positioning effect.

[0037] As Figures 1 - 10 shown, the moving member includes a guide seat 17, a connecting plate 18, a cylinder 19, and a support seat 20. The guide seat 17 is fixed to the top of the processing table 11. The moving frame 16 is slidably arranged on the guide seat 17. The connecting plate 18 is fixed to one side of the moving frame 16. The support seat 20 is located on one side of the guide seat 17 and is fixed to the top of the processing table 11. The cylinder 19 is installed on the top of the support seat 20. The output end of the cylinder 19 is fixedly connected to the connecting plate 18. During use, the controller controls the cylinder 19 to operate. The cylinder 19 can drive the moving frame 16 to slide on the guide seat 17 through the connecting plate 18, thereby realizing the movement of the pressing block 15.

[0038] The specific working process of the present invention is as follows: First, the electric gripper 14 is used to clamp one end of the piston pin. Subsequently, the controller controls the cylinder 19 to operate. The cylinder 19 can drive the moving frame 16 to slide on the guide seat 17 through the connecting plate 18, thereby realizing the movement of the pressing block 15, so that the pressing block 15 can press the other end of the piston pin, improving the positioning effect. Subsequently, the position of the cutting tool 25 is adjusted by the first electric slide 21 and the second electric slide 23. When boring the piston pin, the controller controls the motor 13 to work. The motor 13 can drive the electric gripper 14 to rotate on one side of the side plate 12, so as to drive the piston pin to rotate. At the same time, the controller controls the first electric slide 21 to work. The first electric slide 21 drives the first moving plate 22, the second electric slide 23, the second moving plate 24 and the cutting tool 25 to move along the length direction of the piston pin, and the cutting tool 25 is used to cut the piston pin. At the same time, a storage device for storing cooling water is used to convey the coolant into the inside of the conveying pipe 33, and then the coolant is conveyed into the water spraying pipe 30 through the hose 32 and the connecting pipe 31, and the coolant is sprayed out through the water spraying pipe 30; When the first moving plate 22 drives the second mounting plate 54 to move, the second mounting plate 54 can drive the inserting rod 52 and the gear 55 fixed at the end of the inserting rod 52 to move. Since the gear 55 meshes with the rack 56, the gear 55 can rotate along the axis of the gear 55 when moving, so as to drive the inserting rod 52 to rotate on the second mounting plate 54. When the inserting rod 52 rotates, the rotating sleeve rod 50 can be driven to rotate on the first mounting plate 49 under the cooperation of the limiting groove 51 and the limiting strip 53, so as to drive the second sprocket 47 to rotate. Under the action of the chain 48, when the second sprocket 47 rotates, the turntable 42 can be driven to rotate. When the turntable 42 rotates, the swinging of the rotating rod 44 can be realized through the cooperation of the inserting column 43 and the strip-shaped groove 45, so as to drive the second belt pulley 39 to swing reciprocally on the first vertical plate 35. Under the action of the transmission belt 40, when the second belt pulley 39 swings reciprocally, the first belt pulley 38 can be driven to swing reciprocally, so as to drive the swinging rod 36 to swing reciprocally. The swinging rod 36 can drive the arc-shaped plate 28 to move reciprocally above the arc-shaped guide rail 26 through the connecting rod 37, so as to drive the water spraying pipe 30 to move reciprocally through the mounting block 29, so that the water spraying pipe 30 can move reciprocally in the top, side and bottom directions of the cutting tool 25, so as to realize the water spraying and cooling of the top, side and bottom positions of the boring area, and can continuously adjust the water flow direction during boring, ensure that the coolant can accurately cover the cutting area, avoid the spraying blind area caused by single-point spraying, so as to achieve an effective cooling effect, reduce the temperature and friction force during cutting, and further improve the cutting efficiency and the service life of the cutting tool. That is, when the cutting tool 25 moves along the piston pin for cutting, the rotating assembly can be driven to work synchronously, so that the water spraying pipe 30 on the supporting assembly can realize reciprocating swing. That is, when the cutting tool 25 moves, the reciprocating swing of the water spraying pipe 30 can be realized, with high synchronism, realizing multi-directional spraying and cooling of the cutting tool 25, increasing the coverage area of the coolant, and reducing the temperature of the cutting area.
