Description

Technical Field

[0001] The present invention relates to the technical field of grinding equipment, and particularly relates to a surface grinding equipment for machining an electronic throttle valve. Background Art

[0002] The surface grinding of the electronic throttle valve machining aims to ensure the performance and precision of the throttle body, which is a key link in the production process. During machining, first, the burrs and surplus after casting or forging are removed by rough grinding to initially level the surface, and then, with fine grinding or even mirror grinding processes, fine-grained abrasives, grinding paste, etc. are used to further improve the surface finish and dimensional accuracy, and reduce the air flow resistance. Most grinding equipment adopts an automated robot grinding system and a numerically controlled grinding machine tool to accurately control the grinding path, force, and speed. In terms of quality control, a surface roughness measuring instrument, a coordinate measuring machine, etc. are used to detect the surface roughness and key dimensions, and visual inspection and optical magnifying glasses are combined to check the appearance, ensuring that the inner wall of the throttle valve after grinding can achieve good intake efficiency, sealing performance, and control accuracy to meet the high-performance requirements of the engine; When the existing grinding equipment grinds the inner cavity of the throttle valve, the surface of the grinding wheel will have a roughness decrease due to grinding waste chips embedding in the surface of the grinding wheel, and when fixing the throttle valve, the throttle valve is prone to looseness, affecting the grinding accuracy. Therefore, we propose a surface grinding equipment for machining an electronic throttle valve. Summary of the Invention

The rotary drive assembly is started, and the output end of the rotary drive assembly drives the clamping assembly to rotate, thereby driving the throttle to rotate. The grinding assembly is started, and the grinding assembly is close to the throttle to grind the inner wall of the throttle to achieve the roughness required by the design. The smooth inner wall helps to form a good seal between the throttle valve plate and the inner wall to prevent intake leakage, and can also reduce air flow resistance, allowing air to enter the engine more smoothly, thereby improving intake efficiency and ensuring the power output and fuel economy of the engine. The grinding assembly has a corrugated structure at a position directly below the grinding position. When grinding, the grinding waste can be received in the depression to facilitate the collection of the waste. The cleaning assembly can clean the waste on the top of the grinding assembly to facilitate further recycling.

[0004] Furthermore, the grinding assembly includes a slide cylinder, which is fixedly connected to the top of the base plate, a fixed frame is arranged directly above the slide cylinder, and the bottom of the fixed frame is fixedly connected to the output end of the slide cylinder, the inner side surface of the fixed frame is fixedly connected to a grinding drive assembly, and the side of the grinding drive assembly away from the fixed frame is fixedly connected to an electric grinder, and the slide cylinder is started, and the output end of the slide cylinder drives the fixed frame, the grinding drive assembly, and the electric grinder to move, and finally drives the electric grinder to enter the throttle valve, and the electric grinder runs to grind the inner wall of the throttle valve. At the same time, the grinding drive assembly drives the electric grinder to revolve, and the rotation direction is opposite to the rotation direction of the throttle valve, so that the relative speed is increased and the grinding efficiency is improved.

[0005] Furthermore, the grinding drive assembly includes an electric rotating rod, the outer side surface of the electric rotating rod is fixedly connected to the inner side surface of the fixed frame, and the output end of the electric rotating rod is rotatably connected to the inner side surface of the fixed frame, the side of the electric rotating rod close to the clamping assembly is fixedly connected to an electric slide rail, the side of the electric slide rail away from the electric rotating rod is fixedly connected to the side of the electric grinder away from the clamping assembly, and the output end of the electric slide rail is fixedly connected to the electric grinder, when the electric rotating rod is started, the output end of the electric rotating rod drives the electric slide rail and the electric grinder to rotate, and when the electric slide rail is started, the electric slide rail drives the electric grinder away from the rotation center of the electric rotating rod, thereby adjusting the grinding thickness and adapting to throttle inner walls of different diameters.

[0006] Furthermore, the electric grinder includes a shell, a side of the shell away from the clamping assembly is fixedly connected to the output end of the electric slide rail, the inner side of the shell is rotatably connected to a grinding wheel body through a rotating rod, and the electric grinder is started, and the output end of the electric grinder drives the grinding wheel body to rotate, thereby grinding the inner wall of the throttle valve.

[0007] Furthermore, a flange pipe is fixedly connected to one side of the outer shell away from the grinding wheel body. A material storage cavity is formed inside the outer shell, and the material storage cavity is communicated with the flange pipe. A groove plate is arranged at the interval between the grinding wheel body and the outer shell. One side of the groove plate away from the grinding wheel body is fixedly connected to the outer shell. One side of the groove plate away from the outer shell is slidably connected to the outer side surface of the grinding wheel body. And there is a gap between one side of the groove plate located directly above the center of the grinding wheel body and the grinding wheel body. A communication hole is formed in the inner side surface of the material storage cavity, and the material storage cavity is communicated with the groove plate through the communication hole. The grinding paste is communicated through the flange pipe. The grinding paste enters the material storage cavity through the flange pipe, and then enters the groove plate through the communication hole. The grinding paste contacts the grinding wheel body. With the rotation of the grinding wheel body, the grinding wheel body carries part of the grinding paste to grind the throttle valve. The setting of the gap can limit the thickness of the applied grinding paste and ensure uniform grinding. One side of the groove plate close to the center of the grinding wheel body scrapes the grinding wheel body to scrape off the grinding waste chips, ensuring the roughness of the grinding wheel body and the grinding effect. And the unutilized grinding paste falls onto the inner wall of the throttle valve and continues to participate in grinding, which can make full use of the grinding paste.

[0008] Furthermore, a flexible plate is fixedly connected to the inner wall of the sliding table cylinder. One end of the flexible plate away from the inner wall of the sliding table cylinder is fixedly connected to one side of the fixed frame close to the clamping assembly. The flexible plate is arranged in a waveform. A waveform groove is formed in one side of the sliding table cylinder away from the bottom plate, and the groove shape of the waveform groove is the same as that of the flexible plate. When the fixed frame moves, it drives the flexible plate to fold. The flexible plate can block the sliding table cylinder to prevent waste chips from entering the inside of the sliding table cylinder. The waveform depression of the flexible plate can also collect the waste chips combined with the grinding waste chips and the grinding paste.

[0009] Furthermore, the cleaning assembly includes a receiving box. The receiving box is fixedly connected to the top of the bottom plate, and the outer side surface of the receiving box is fixedly connected to the outer side surface of the sliding table cylinder. A support plate is fixedly connected to one side of the sliding table cylinder away from the receiving box, and the support plate is fixedly connected to the top of the bottom plate. An expansion link is arranged on one side of the support plate away from the bottom plate. The surface of the expansion link is fixedly connected to the inner side surface of the support plate. One end of the expansion link away from the support plate is fixedly connected to a scraper, and the scraper is fixedly connected to the output end of the expansion link. One side of the scraper close to the bottom plate is slidably connected to the waveform groove and the flexible plate. The expansion link is started, and the output end of the expansion link drives the scraper to move. The scraper scrapes the top of the waveform groove and the flexible plate, and finally pushes the waste chips into the receiving box to complete the collection of the waste chips. At the same time, the waveform surface of the scraper straightens the flexible plate horizontally to maintain the shape of the flexible plate and ensure the shielding effect of the flexible plate on the sliding table cylinder.

[0010] Further, the rotation drive assembly includes a motor. The outer side surface of the motor is fixedly connected to the inner side surface of the mounting frame. One side of the motor near the center of the bottom plate is fixedly connected to a rotating shaft, and the rotating shaft is fixedly connected to the output end of the motor. The surface of the rotating shaft is rotatably connected to the inner side surface of the mounting frame. The end of the rotating shaft away from the motor is fixedly connected to a chuck. The inner side surface of the chuck is slidably connected to the clamping assembly, and the output end of the chuck is fixedly connected to the clamping assembly. The clamping assembly fixes the electronic throttle. Start the motor, the output end of the motor drives the rotating shaft to rotate, drives the chuck to rotate, and finally drives the throttle to rotate. The throttle rotates in the opposite direction to the revolution direction of the grinding wheel body, achieving efficient grinding.

[0011] Further, the clamping assembly includes positioning posts. There are four positioning posts, and the four positioning posts are respectively fixedly connected to the four output ends of the chuck. One side of the positioning post away from the center of the chuck is fixedly connected to a driving arm. The output end of the driving arm is fixedly connected to a driving plate. The inner side surface of the chuck is fixedly connected to a sliding rod. The outer side surface of the sliding rod is slidably connected to the inner side surfaces of the positioning post and the driving arm. One side of the driving arm away from the driving plate is fixedly connected to a spring, and the spring is sleeved outside the sliding rod. The end of the spring away from the driving arm is fixedly connected to the surface of the sliding rod. The output end of the chuck drives the positioning post, the driving arm, and the driving plate to move, so as to adapt to throttles of different sizes. The driving arm and the positioning post slide on the surface of the sliding rod to achieve limiting, and the spring contracts for buffering. Start the driving arm, and the driving arm drives the driving plate to approach the positioning post, thereby clamping the throttle.

[0012] Further, a threaded hole is opened at the end of the positioning post away from the chuck. One side of the driving plate close to the positioning post is fixedly connected to a screw rod. The screw rod is threadedly connected to the threaded hole, and the screw rod is fixedly connected to the output end of the driving plate. The driving plate drives the screw rod to rotate. The screw rod is threadedly connected to the throttle, and finally threadedly connected to the threaded hole, realizing a more firm fixation, preventing the throttle from loosening when rotating. And when the screw rod is adapted to the throttle and the screw rod can pass through the throttle, the screw rod is still adapted to the threaded hole and can still realize a firm fixation.

[0013] The beneficial effects of the present invention are as follows: 1. By setting a grinding mechanism in the present invention, the grinding assembly grinds the inner wall of the throttle to reach the required roughness. The smooth inner wall helps to form a good seal between the throttle valve plate and the inner wall, preventing air leakage, and can also reduce the air flow resistance, allowing air to enter the engine more smoothly, thereby improving the intake efficiency and ensuring the power output and fuel economy of the engine. The position of the grinding assembly directly below the grinding position has a waveform structure. During grinding, the grinding waste can be received in the recesses, facilitating the collection of waste. The cleaning assembly can clean the waste on the top of the grinding assembly, facilitating further recycling.

[0014] 2. The present invention improves the grinding efficiency by setting a grinding assembly. The grinding drive assembly drives the electric grinder to revolve, and the rotation direction is opposite to that of the throttle valve, increasing the relative speed. The electric slide rail drives the electric grinder away from the rotation center of the electric rotating rod, thereby adjusting the grinding thickness and adapting to the inner walls of throttle valves with different diameters.

[0015] 3. The present invention sets a groove plate. The gaps of the groove plate can limit the thickness of the applied grinding paste to ensure uniform grinding. One side of the groove plate close to the center of the grinding wheel body scrapes the grinding wheel body to scrape off the grinding waste, ensuring the roughness of the grinding wheel body and the grinding effect. Moreover, the unutilized grinding paste that falls onto the inner wall of the throttle valve continues to participate in grinding, making full use of the grinding paste.

[0016] 4. The present invention sets a cleaning assembly. The flexible plate can shield the slide cylinder to prevent waste chips from entering the inside of the slide cylinder. The waveform depressions of the flexible plate can also collect the waste chips combined with the grinding waste and the grinding paste. The scraper scrapes the waveform grooves and the top of the flexible plate to push the waste chips into the accommodating box to complete the collection of the waste chips. At the same time, the waveform surface of the scraper straightens the flexible plate horizontally to maintain the shape of the flexible plate and ensure the shielding effect of the flexible plate on the slide cylinder.

[0017] 5. The present invention sets a clamping assembly. The driving arm drives the driving plate to approach the positioning post to clamp the throttle valve. The screw is threadedly connected to the throttle valve and finally threadedly connected to the screw hole to achieve a more firm fixation, preventing loosening when the throttle valve rotates. And when the screw is adapted to the throttle valve and the screw can pass through the throttle valve, the screw is still adapted to the screw hole and can still achieve a firm fixation.
