Description

Technical Field

[0001] The present invention belongs to the technical field of cutting processing, and relates to a mechanical chemical effect reagent coating and drying device and method for curved surface parts used in a milling machine. Background Art

[0002] Milling is one of the most widely used cutting methods in machining. The magnitude of the cutting force during milling directly affects the machining efficiency, surface quality, and tool life. In order to reduce the cutting force while ensuring the machining quality, weakening the material surface to reduce the cutting load is a technical means with broad application prospects. As a new type of material surface weakening technology, the mechanochemical effect can significantly reduce the cutting force during machining by coating a specific reagent on the material surface. The principle is that a strong adsorption effect is formed between the surfactant molecules and the atoms of the metal material to be machined. During the deformation process of the material, this adsorption effect promotes the movement of dislocations, making the material easier to deform and finally break. Applying this effect to the machining process can not only reduce the machining energy consumption but also reduce tool wear.

[0003] Currently, due to the diverse surface shapes of the workpieces processed by milling machines, and mainly complex structures, the coating method of the reagent still uses manual operation. The characteristics of the mechanochemical effect also require that machining can only be carried out after the reagent is dried, which not only increases the workload of personnel but also greatly reduces the machining efficiency. After retrieval, the patent with the authorized publication number CN118976646B in China proposes a coating treatment device for mechanical parts. The device mainly consists of a coating driving mechanism and a vacuum-breaking mechanism. The coating driving mechanism sprays the coating on the surface of the part, and then enters the vacuum-breaking mechanism to remove the surface bubbles to make the coating evenly distributed. The coating device proposed by this invention is relatively large in size and requires sufficient space for device layout. Moreover, the vacuum-breaking mechanism requires a closed space, which determines that the device does not meet the requirements for use on a milling machine and lacks a drying device to meet the requirements of mechanochemical effect reagent coating.

[0004] Therefore, it is particularly necessary to invent a mechanochemical effect reagent coating and drying device and method that can be used on a milling machine and adapt to the workpiece surface with curvature changes to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the pain points of the current lack of an automatic coating device for use on a milling machine, and to propose a mechanochemical effect reagent coating and drying device and method for curved surface parts used in a milling machine.

[0006] To achieve the above technical objectives, the technical solutions adopted by the present invention are as follows:

[0007] A mechanical-chemical effect reagent coating and drying device for curved parts used in a milling machine, comprising a rear-pulling tool holder of the milling machine. A coating mechanism is installed on the rear-pulling tool holder of the milling machine. The coating mechanism includes an installation valve plate, an air nozzle, a reagent nozzle, a brush mounting plate, a brush, a spring and a snap ring. The reagent nozzle, the brush mounting plate and the air nozzle are sequentially installed on the installation valve plate from front to back. The workpiece is placed below the coating mechanism. The reagent nozzle and the air nozzle are facing the workpiece. A reagent channel and an air channel are arranged inside the installation valve plate. The reagent channel is communicated with the reagent nozzle, and the air channel is communicated with the air nozzle. The reagent can be sprayed out through the reagent nozzle via the reagent channel, and the air can be sprayed out from the air nozzle through the air channel. The brush is elastically installed on the brush mounting plate through the spring and the snap ring, and the brush can float up and down to contact the curved surface of the workpiece.

[0008] To optimize the above technical solution, the specific measures taken also include:

[0009] The above-mentioned mechanical-chemical effect reagent coating and drying device for curved parts used in a milling machine further includes a control cabinet, which includes a programmable logic controller, a pressure reducing valve, a two-position two-way direct-acting valve, a liquid supply device and an air heating module.

The liquid supply device is connected to the pressure reducing valve, the pressure reducing valve is connected to the two-position two-way direct-acting valve, and the two-position two-way direct-acting valve is connected to the reagent channel. When the programmable logic controller starts the liquid supply device and the two-position two-way direct-acting valve, the liquid supply device can input the reagent into the reagent channel. The air heating module is connected to the air channel, and the programmable logic controller can control the air heating module to heat the air and input the heated air into the air channel.

[0010] The above-mentioned rear-pulling tool holder of the milling machine is connected to the coating mechanism through a steering mechanism. The steering mechanism includes a mounting flange, a rotary table and a speed sensor. The upper end of the mounting flange is fixedly connected to the rear-pulling tool holder of the milling machine, and the lower end is fixedly connected to the rotary table. The rotary table can rotate in the horizontal direction. The lower end of the rotary table is fixedly connected to the installation valve plate. The speed sensor is fixed to the top of the mounting flange with screws. The speed sensor is used to sense the moving direction of the rear-pulling tool holder of the milling machine. The control cabinet includes a rotary table motor driver. Both the speed sensor and the rotary table motor driver are signal-connected to the programmable logic controller. The programmable logic controller can, according to the moving direction of the rear-pulling tool holder of the milling machine transmitted by the speed sensor, make the rotary table motor driver control the rotation of the rotary table, so that the front-rear direction of the coating mechanism is consistent with the front-rear direction of the movement of the rear-pulling tool holder of the milling machine.

[0011] The above-mentioned coating mechanism includes a baffle, which is fixed on the installation valve plate and also surrounds the reagent nozzle to block the reagent splashing out from the reagent nozzle in all directions.

[0012] The above-mentioned brush mounting plate is a "C"-shaped plate. The upper end of the "C"-shaped plate is fixedly connected to the mounting valve plate. A perforation is provided at the lower end of the "C"-shaped plate. A connecting bolt passes through the perforation. The upper end of the connecting bolt is connected to a circlip, and the lower end is connected to a brush. A spring is sleeved on the connecting bolt. The upper end of the spring abuts against the lower surface of the brush mounting plate, and the lower end abuts against the brush. The brush can move up and down relative to the brush mounting plate.

[0013] The above-mentioned air heating module includes a heating block, a spiral copper tube, a housing, a plug, and two copper tube connectors at the front and back. The heating block is placed in the middle of the spiral copper tube. The spiral copper tube is clamped on the housing. The plug is threadedly connected to the housing. The copper tube connectors are threadedly installed at both ends of the spiral copper tube. The front copper tube connector is connected to a blower, and the rear copper tube connector is connected to an air passage.

[0014] An optoelectronic sensor is installed on the above-mentioned mounting valve plate. The optoelectronic sensor is used to sense the distance between the coating mechanism and the workpiece. The optoelectronic sensor is signal-connected to a programmable logic controller.

[0015] The above-mentioned mounting valve plate is provided with a reagent passage connector at the end of the reagent passage. The reagent passage connector is connected to the outlet of a two-position two-way direct-acting valve through a hose. The mounting valve plate is provided with an air passage connector at the end of the air passage. The air passage connector is connected to the rear copper tube connector through a hose.

[0016] A usage method of a mechanical chemical effect reagent coating and drying device for curved surface parts of a milling machine, applying the above-mentioned mechanical chemical effect reagent coating and drying device for curved surface parts of a milling machine, specifically includes the following steps:

[0017] Step 1: The rear-pulling tool holder of the milling machine drives the coating mechanism to run above the workpiece. The programmable logic controller starts the two-position two-way direct-acting valve, the liquid supply device, and the air heating module. The liquid supply device injects reagent into the reagent passage, and the air heating module inputs hot air into the air passage. The rear-pulling tool holder of the milling machine drives the coating mechanism to move forward, so that the reagent nozzle, the brush, and the air nozzle pass by the workpiece in sequence.

[0018] Step 2: The reagent is sprayed on the surface of the workpiece through the reagent nozzle; then the brush spreads the unevenly distributed reagent on the surface of the workpiece evenly. Due to the existence of the spring, when there is a curvature change on the surface of the workpiece, the brush can float up and down to ensure fitting with the surface of the workpiece. Finally, hot air is ejected from the air nozzle to dry the evenly spread reagent.

[0019] Step 3: The programmable logic controller closes the two-position two-way direct-acting valve, the liquid supply device, and the air heating module to complete the reagent coating and drying of the workpiece.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. In the present invention, by providing a brush, the brush is fixed on the brush mounting plate by a spring and a retaining ring. Due to the presence of the spring, when there are undulations on the surface of the machined part, the spring allows the brush to float up and down, thus avoiding the phenomenon of uneven application of the reagent during spraying. Multiple brushes can be provided in the present invention, and different brushes can move independently to adapt to local curvature changes on the part surface.

[0022] 2. In the present invention, by providing a commutation mechanism, the commutation mechanism consists of a rotary table and a speed sensor. During the coating process, since the coating mechanism operates in a certain sequence, it is necessary to ensure that the nozzle is in the front and the air nozzle is in the back so as to realize the processes of spraying the reagent, applying the reagent, and drying the reagent. Therefore, it is necessary to ensure that the coating mechanism is consistent with the movement direction. After the rotary table and the speed sensor are calibrated, the rotary table can adjust the entire coating mechanism according to the speed direction of the speed sensor to make it consistent with the movement direction. Thus, when planning the coating path, there is no need to consider the commutation problem, and only the entire surface coverage needs to be achieved, which can reduce the idle stroke and improve the programming efficiency.

[0023] 3. In the present invention, by providing a mounting flange, it can be connected to the existing rear-pull tool holder of the milling machine, and the device body is installed on the spindle of the milling machine, thereby reducing the occupation of the milling machine space. Moreover, through the spindle installation, the coating path can be planned using the milling machine programming.

[0024] 4. In the present invention, by providing an air heating module, the air at the inlet of the air nozzle can be heated to an appropriate temperature, thereby accelerating the drying of the reagent and improving the operating speed of the coating device.

[0025] 5. In the present invention, by providing a baffle, since the reagent is ejected through the nozzle and the spraying range is not easy to control, it may be sprayed outside the area where the part is located, resulting in waste of the reagent and environmental pollution. The presence of the baffle can prevent the reagent from being sprayed onto other areas. After being sprayed onto the baffle, it flows back along the inner wall of the baffle to the surface of the workpiece, avoiding waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The present invention discloses a mechanical chemical effect reagent coating and drying device for curved parts of a milling machine, as Figures 1-6 shown, which includes a rear-pulling tool holder 1 of the milling machine, a coating mechanism and a control cabinet 5. The coating mechanism includes a mounting valve plate 11, an air nozzle 13, a reagent nozzle 18, a spring 16, a brush 15, a brush mounting plate 14, and a snap ring 21. The reagent nozzle 18 and the air nozzle 13 are threadedly connected to the mounting valve plate 11. The brush mounting plate 14 is fixed to the mounting valve plate 11 by screws. A groove is designed at the top of the brush 15, and it is fixed to the brush mounting plate 14 by the snap ring 21 and the spring 16.

[0038] In order to spray the surface active reagent on the surface of the workpiece, a reagent channel and an air channel are designed inside the mounting valve plate 11. The reagent is transmitted to the reagent nozzle 18 through a reagent channel joint 20 and the reagent channel. In order to prevent the reagent from contaminating other places when spraying, a baffle 17 is provided to limit the spraying range of the reagent. The reagent on the baffle 17 can flow back to the surface of the workpiece, thus avoiding waste.

[0039] In order to make the reagent sprayed on the surface of the workpiece evenly distributed, a brush 15 is provided behind in the moving direction. A spring 16 is provided between the brush 15 and the brush mounting plate 14. Due to the existence of the spring 16, when the surface of the workpiece is a curved surface, the brush 15 can float up and down, so as to achieve uniform coating on the curved surface.

[0040] In order to accelerate the drying speed of the mechanochemical effect reagent, two rows of air nozzles 13 are provided behind the brush 15. The air nozzles 13 are connected to the air passage joint 12 through the air passage inside the mounting valve plate 11. The air passage joint 12 is connected to the air heating module in the control cabinet 5. The heating block 24 in the air heating module is arranged in the middle of the spiral copper tube 22. The excellent thermal conductivity of copper is utilized to heat the air in the spiral copper tube 22, so that hot air is ejected from the air nozzles 13 to accelerate the drying of the reagent.

[0041] During the use of this embodiment, the whole coating mechanism is driven by the milling machine spindle. The photoelectric sensor 19 senses through distance that the coating mechanism has run above the workpiece. Since there is a certain distance between the reagent nozzle 18 and the photoelectric sensor 19, after receiving the signal from the photoelectric sensor 19, the programmable logic controller 9 starts the two-position two-way direct-acting valve 8 after a period of delay. The liquid supply device 6 is started by air pressure, and the reagent is transported to the reagent nozzle 18 through a hose and sprayed on the surface of the workpiece; then the brush 15 smears the unevenly distributed reagent on the workpiece surface evenly. Due to the existence of the spring 16, when there is a curvature change on the workpiece surface, the brush 15 can float up and down to ensure the fit with the surface. At the same time as the liquid supply device 6 is started, the air heating module is also started at the same time. Hot air is ejected from the air nozzles 13 behind the brush 15 to dry the evenly smeared reagent. When the photoelectric sensor 19 senses through distance that it has left the workpiece surface, the programmable logic controller 9 closes the two-position two-way direct-acting valve 8, the liquid supply device 6 and the air heating module after a period of delay to prevent the reagent from being sprayed on the milling machine platform and polluting the environment.

[0042] The present invention has a further embodiment:

[0043] A mechanochemical effect reagent coating and drying device for curved parts of a milling machine. In order to keep the coating mechanism in the same direction as the moving direction, it is installed below the reversing mechanism through screws. The reversing mechanism includes a rotary table 4, a mounting flange 3, a speed sensor 2, and a milling machine pull-back tool holder 1. The rotary table 4 is connected to the mounting flange 3 through screws. The mounting flange 3 and the milling machine pull-back tool holder 1 are clamped and connected through a collet. The whole reversing mechanism can be installed on the milling machine spindle through the milling machine pull-back tool holder 1.

[0044] During use of this example, the rotary slide 4 first calibrates the zero point positions of its own angular displacement sensor and the speed sensor 2 to make the zero point directions of the two consistent. During operation, the speed sensor 2 monitors the movement direction of the spindle in the XY plane in real time, and feeds back to the rotary slide motor driver 10, and drives the rotary slide 4 to rotate to the corresponding angle according to the change in the movement direction, thereby driving the coating mechanism to make its direction consistent with the movement direction, simplifying the work of coating path planning, and because it can be reversed, the movement in the opposite direction can be achieved without idle stroke, thereby improving work efficiency.

[0045] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principles of the present invention shall be equivalent replacement methods and shall be included in the protection scope of the present invention.
