Figures 1 to 6 As shown, the base 40 is a device for improving the surface processing quality of a workpiece fixed as a whole and connected to a support plate of a machine tool body. The base 40 is made of a metal material with good rigidity to ensure that it will not deform during processing.

[0062] The device for improving the surface processing quality of a workpiece provided in the present application can specifically be used to prepare a gradient nanostructure on the surface of a metal material of a rotating part.

[0063] The tool system 10 includes two tool systems 10, which are arranged opposite to each other. The force directions of the two tool systems 10 on the workpiece 30 extend in the horizontal direction. The force directions of the two tool systems 10 on the workpiece 30 can be arranged in a collinear manner. In this case, the connecting line of the force directions of the two tool systems 10 on the workpiece 30 can pass through the rotation center of the workpiece 30 or be arranged offset from the rotation center of the workpiece 30.

[0064] In a specific embodiment, two vibration reduction modules 20 are symmetrically arranged on opposite sides of the workpiece 30, and the force directions of the two vibration reduction modules 20 on the workpiece 30 are on the same straight line. For example, the two vibration reduction modules 20 are symmetrically arranged on the left and right sides of the workpiece 30.

[0065] During specific assembly, the tool system 10 is installed on the base 40 through the support base 109. The support base 109 is installed in two installation holes set on the left and right of the base 40, and the vibration reduction module 20 is installed in two installation holes set on the front and back of the base 40.

[0066] In the present invention, the force direction of the tool system 10 on the workpiece 30 and the force direction of the vibration reduction module 20 on the workpiece 30 are coplanar, and such an arrangement further reduces the vibration of the workpiece 30 .

[0067] During specific assembly, the tool system 10 is installed on the base 40 as a whole through the support seat 109. The support seat 109 is installed in two mounting holes set on the left and right of the base 40, and the vibration reduction module 20 is installed in two mounting holes set on the front and back of the base 40. During the arrangement, the center line of the mounting hole can be coplanar with the force direction of the tool system 10 on the workpiece 30 to be processed.

[0068] In another embodiment, one direction in which the forces applied by the two tool systems 10 to the workpiece 30 are higher than the rotation centerline of the workpiece 30 , and the other direction in which the forces applied by the two tool systems 10 are lower than the rotation centerline of the workpiece 30 .

[0069] The vibration reduction modules 20 include two vibration reduction modules 20, which are respectively attached to opposite ends of the workpiece 30. In one specific embodiment, the two vibration reduction modules 20 are symmetrically arranged at the left and right ends of the workpiece 30. In another embodiment, the two vibration reduction modules 20 are symmetrically arranged at the top and bottom ends of the workpiece 30.

[0070] The present application provides a device for improving the surface processing quality of a workpiece, which is modified by a commonly used commercial machine tool on the market and is verified for use after batch processing.

[0071] When a device for improving the surface processing quality of a workpiece is used to process a workpiece 30, the tool system 10 and the vibration reduction module 20 are both installed on the base 40, and then the base 40 is installed on the machine tool body of the machine tool system. The two vibration reduction modules 20 are respectively attached to the opposite sides of the workpiece 30 to be processed, and the two tool systems 10 are set to clamp the workpiece 30. During processing, the machine tool base 40 is fed back and forth along the Y axis (the length direction of the workpiece) to process the workpiece 30. As the processing proceeds, the relative position of the device for improving the surface processing quality of a workpiece and the workpiece 30 to be processed changes. The workpiece 30 to be processed can specifically be a metal workpiece to be processed.

[0072] In one embodiment, the same workpiece 30 to be processed can be processed using a set of devices for improving the surface processing quality of the workpiece.

[0073] In another embodiment, the same workpiece 30 is processed simultaneously using two sets of devices for improving the surface processing quality of the workpiece, which effectively offsets the force that causes the bending deformation of the workpiece 30. When the workpiece 30 of metal material is nano-processed, the devices for improving the surface processing quality of the workpiece located at the left and right ends apply pressure to the surface of the metal material from both ends and roll with the workpiece, and at the same time, the devices for improving the surface processing quality of the workpiece are adjusted according to the vibration of the workpiece 30 to stabilize the vibration within a reasonable range.

[0074] It can be seen from the above description that in a device for improving the surface processing quality of a workpiece provided in a specific embodiment of the present application, a vibration reduction module 20 is integrated in the device for improving the surface processing quality of a workpiece.

Specifically, the isolation distance between the first magnetic member 509 and the second magnetic member 5013 is the size of the tool assembly height fine adjustment.

[0086] The first magnetic member 509 and the second magnetic member 5013 may be electromagnetic coils, or two electromagnetic plates.

[0087] like Fig.21 As shown, the tool assembly includes a knife ball seat 102, a knife head seat 103 and a knife ball 101, a pressure sensor 104 and the knife ball seat 102 are installed at opposite ends of the knife head seat 103, and the knife ball 101 is installed at one end of the knife ball seat 102 away from the pressure sensor 104. Specifically, in order to facilitate disassembly and assembly, the knife ball seat 102 is threadedly connected to the knife head seat 103, and specifically, a stud is provided at the threaded connection position of the knife ball seat 102 or the knife head seat 103, and a threaded hole is provided at the other.

[0088] In a specific embodiment, the pressure regulating device includes a hydraulic module and a pressure regulating module, and the pressure sensor 104 is used to sense the pressure of the tool assembly. The hydraulic module 105 is connected to the tool assembly to provide the tool assembly processing pressure. The pressure regulating module 106 is connected to the tool assembly to provide the pneumatic module processing pressure, and the pressure response speed of the pressure regulating module 106 applied to the tool assembly is greater than that of the hydraulic module 105. During specific assembly, the pressure sensor 104 is installed on the housing of the hydraulic module 105 through the first fastener.

[0089] The pressure regulating module 106 is a pneumatic module, and a push rod 1015 of the pneumatic module is connected to the housing of the hydraulic module 105. The pneumatic module includes a housing and a push rod 1015 arranged on the housing, and the output end of the push rod 1015 acts on the end of the hydraulic module 105 away from the pressure sensor 104. A chamber for installing a piston at the end of the push rod 1015 is provided in the housing, and the housing is provided with a gas quick connector connected to the chamber, wherein two gas quick connectors are provided, namely, a first pneumatic quick connector 1010 and a second pneumatic quick connector 1011, so as to facilitate the connection of the housing with the gas source to realize the air intake and exhaust of the chamber.

[0090] The pressure sensor 104 and the pressure regulating module 106 are located on opposite sides of the hydraulic module 105 . A guide module for guiding the movement direction of the pressure regulating module 106 is provided between the housing of the pressure regulating module 106 and the housing of the hydraulic module 105 .

[0091] like Figures 1 to 3 As shown, specifically, the guide module can be a guide column 107 , and one of the housing of the pressure regulating module 106 and the housing of the hydraulic module 105 is fixedly connected to the guide column 107 , and the other is slidably connected to the guide column 107 .

[0092] When the tool system 10 is in working state, the hydraulic module 105 and the pressure sensor 104 module are both in a state of pressurizing the tool assembly.

[0093] The pressure sensor 104, the hydraulic module 105 and the pressure regulating module 106 are all connected to the motion control module. Specifically, the pressure sensor 104, the hydraulic module 105 and the pressure regulating module 106 can realize signal transmission with the motion control module through wire electrical connection or wireless communication.

[0094] When the pressure value received by the action control module from the pressure sensor 104 rises to a value exceeding the first pressure value within a preset time, the action control module controls the pressure regulating module 106 to reduce the pressure of the tool assembly; when the pressure value received by the action control module from the pressure sensor 104 drops to a value exceeding the second pressure value within a preset time, the action control module controls the pressure regulating module 106 to increase the pressure of the tool assembly. Specifically, the tool assembly can be a traditional tool for processing parts. The first pressure value and the second pressure value are determined according to the pressure of the tool assembly and the part processing. The preset time period is set as required.

[0095] Specifically, when the action control module receives the pressure value of the pressure sensor 104 and the pressure value rises by a value exceeding the first pressure value of the preset pressure range within the preset time, the action control module controls the pressure regulating module 106 to reduce the pressure of the tool assembly; when the action control module receives the pressure value of the pressure sensor 104 and the pressure value drops by a value exceeding the second pressure value of the preset pressure range within the preset time, the action control module controls the pressure regulating module 106 to increase the pressure of the tool assembly. The preset pressure range value is the pressure value required when the tool assembly normally processes parts, and the specific range value can be set according to actual needs, and this application does not make specific limitations.

[0096] When the action control module receives the pressure value of the pressure sensor 104 and the pressure value rises by more than the first pressure value of the preset pressure range within the preset time, the action control module controls the pressure regulating module 106 and the hydraulic module 105 to reduce the pressure of the tool assembly at the same time; when the action control module receives the pressure value of the pressure sensor 104 and the pressure value drops by more than the second pressure value of the preset pressure range within the preset time, the action control module controls the pressure regulating module 106 and the hydraulic module 105 to increase the pressure of the tool assembly at the same time. At this time, the pressure regulating module 106 and the hydraulic module 105 can be used to adjust the pressure of the tool assembly at the same time. During processing, the action control module applies the load according to the process parameters, and the pressure sensor 104 senses the force loading and feeds back to the action control module. According to the changes in the processing process, the pressure can be accurately adjusted in real time to ensure the processing accuracy.

[0097] In terms of specific materials, the knife ball 101 of the tool assembly is made of cemented carbide material, specifically YG6 cemented carbide; the rest is made of bearing steel, and specifically the rest of the parts are all made of hardened tool steel material.

[0098] During operation, the motion control module is first used to return the position of the knife ball 101 to 0. At this time, the force extension line of the knife ball 101 passes through the rotation center line of the workpiece 30 to be processed. Then, the left tool assembly uses the position adjustment device 50 to adjust the tool assembly upward along the Z axis by 0.1 mm, and the right tool assembly uses the position adjustment device 50 to adjust the tool assembly upward along the Z axis by -0.1 mm. The knife ball 101 contacts the workpiece 30, and the hydraulic module applies pressure, which is fed back to the pressure adjustment module by the pressure sensor and remains constant after reaching the set value.

[0099] The power source of the pressure regulating device is a telescopic rod or a motor. Specifically, the pressing force can be provided by the extension and retraction of the telescopic cylinder.

[0100] The pressure controller can be adjusted by a screw. Specifically, the motor drives the screw to rotate, and the end of the screw is threadedly connected to the cutter head seat 103. The position of the cutter head seat 103 is adjusted by rotating the screw forward and backward, thereby adjusting the position of the cutter ball 101.

[0101] In a specific embodiment, the vibration reduction module 20 includes a mounting seat 201, a vibration sensor, and a vibration adjustment device 202 connected to the vibration sensor to adjust the force between the mounting seat 201 and the workpiece 30 to be processed. The vibration sensor is used to measure the amplitude of the mounting seat 201. Specifically, when the amplitude is greater than 0.1 mm, the vibration adjustment device 202 is adjusted. Of course, according to actual conditions, when the vibration adjustment device 202 adjusts the mounting seat 201, the amplitude is not limited to the above situation.

[0102] The vibration sensor is connected to the vibration adjustment device 202 by signal. The mounting seat 201 is provided with a limit groove 203 that fits the workpiece 30. Specifically, the limit groove 203 can be a V-shaped groove opening toward the workpiece 30. The vibration adjustment device 202 can be a cylinder or hydraulic control adjustment device.

[0103] Specifically, the control structure and the motion control module of the vibration adjustment device 202 may be integrated into one control module 60 .

[0104] The limiting groove 203 of the mounting seat 201 is preferably made of polytetrafluoroethylene, which has excellent self-lubricating properties and moderate hardness, and will not scratch the surface of the workpiece 30 during the processing.

[0105] The force application position of the tool system 10 on the workpiece 30 is separated from the rotation centerline of the workpiece 30, and the distance between the force application position of the two tool systems 10 on the workpiece 30 and the rotation centerline of the workpiece 30 is equal. In order to ensure the smooth rolling of the spherical cutter head, the knife balls 101 of the two sets of tool systems 10 abandon the traditional center-to-top method and adopt an eccentric arrangement, which solves the problem of the spherical cutter head getting stuck when a large load is applied to a metal material with high processing strength, making the processing smoother and the tool wear more even.

[0106] In one processing method, two vibration reduction modules 20 are arranged up and down, the two vibration reduction modules 20 are centered and facing each other, and the tool system 10 is arranged left and right, and the two tool systems 10 are eccentrically facing each other, that is, the force direction of the tool system on the workpiece to be processed is isolated from the rotation center line of the workpiece to be processed. When processing metal materials with high strength, the applied load is very large, in order to ensure the smooth rolling of the spherical cutter head. Figure 4 As shown, the two tool systems 10 abandon the traditional centered alignment method and adopt an eccentric arrangement, that is, the left tool head uses the tool position adjustment system to adjust 0.1mm upward along the Z axis, and the right tool head uses the tool position adjustment system to adjust -0.1mm upward along the Z axis, and vice versa.

[0107] During processing, the vibration regulating device 202 reduces the vibration of the rotating part by controlling the two clamping mounting seats 201, and at the same time, the vibration sensor senses the real-time force loading and feeds back to the vibration regulating device 202. The present application uses a closed-loop controlled tool system 10 and a vibration reduction module 20, which are detected by a pressure sensor 104 and a vibration sensor and fed back to the control module. According to the changes in the processing process, the system can be accurately adjusted and responded to in real time, and the workpiece processing and clamping methods can be changed, thereby effectively suppressing the vibration of the workpiece 30 to be processed and the tool system 10, and the fit of the workpiece 30 to be processed is better, and a continuous and stable surface hardening can be formed, which effectively suppresses the "vibration marks" caused by uneven force and the runout and axial straightness deviation caused by the deflection deformation when the slender shaft is processed with a single-sided tool, that is, during the processing process, the problem of tool vibration of the metal material of the workpiece to be processed during the gradient nanostructure processing is reduced.

[0108] The limit groove 203 of the vibration reduction module 20 is made of polytetrafluoroethylene, and the other parts are made of hardened tool steel. The vibration adjustment device 202 uses a hydraulic device. During operation, the limit groove 203 contacts the workpiece 30 to be processed, and the vibration sensor measures the vibration and feeds it back to the control system. When the amplitude is greater than 0.001mm, the vibration adjustment device 202 uses a hydraulic device to tighten the limit groove 203 to the position to be processed, lower its vibration beam, and keep it within 0.001mm.

[0109] During specific processing, the workpiece 30 rotates at a speed of 60 rpm, and the base 40 moves along the Y axis at a speed of 2 mm / s. Of course, the above is only a specific implementation method. According to different requirements of the workpiece 30, the rotation speed of the workpiece to be processed and the moving speed of the base can be appropriately adjusted.

[0110] The present application provides a device for improving the surface processing quality of a workpiece, which can be configured with two sets of back-to-back operations or three sets of segmented operations on a workpiece 30 to be processed.

[0111] The processing equipment designed by this utility model has been used to process rotary hardened steel with different aspect ratios. The processing effect is good and the surface hardening is obvious. The specific test parameters are shown in the following table:
