Technical Field
[0001] This utility model relates to the field of fuel injector control valve grinding and testing technology, specifically to a fuel injector control valve sleeve grinding and testing device. Background Technology
[0002] The fuel injector control valve is an important component used inside the gasoline injector. It usually needs to be precision ground and shaped before it is put into use. Therefore, the grinding and testing of the fuel injector control valve sleeve plays an important role in ensuring the quality of the fuel injector.
[0003] During the grinding process, the injector control valve sleeve needs to be limited by a three-jaw chuck and a push rod, then ground by a grinding device, and finally the size and shape of the valve sleeve are accurately measured by a measuring device.
[0004] The clamps used in the grinding process of valve sleeves are generally three-jaw chucks. When clamping, they occupy a certain distance from the outer surface of the valve sleeve, which means that the grinding process needs to be divided into two or more clamping operations. After each clamping, it is necessary to check and position the valve sleeve to ensure that it is in the center point of the valve sleeve, which makes the inspection quite troublesome.
[0005] Therefore, a grinding detection device for injector control valve sleeve is proposed to solve the problem that multiple clamping and adjustment are required during grinding, which makes detection more troublesome. Utility Model Content
[0006] The technical problem this invention aims to solve is that the grinding process requires multiple clamping and adjustment, which makes the inspection process cumbersome. Therefore, this invention proposes a grinding inspection device for injector control valve sleeves.
[0007] The technical solution adopted by this utility model to solve the technical problem is: a grinding and detection device for an injector control valve sleeve, including an operating table, a top plate, a limiting groove, a first motor, a lead screw, and a sliding plate. A second motor is fixedly connected to the two sliding plates on opposite sides. A rotating drum is fixedly connected to the output end of the second motor. An electric chuck is fixedly connected to one side of the rotating drum. An electric telescopic rod is fixedly connected inside the rotating drum. A connecting plate is fixedly connected to the output end of the electric telescopic rod. A top column is fixedly connected to one side of the connecting plate. An industrial camera is fixedly connected to the center of the bottom end of the top plate. The position of the industrial camera corresponds to that of the operating table.
[0008] As a preferred technical solution of this utility model, a first groove is provided on the operating table, and a second groove is provided on both sides of the first groove on the operating table. A movable plate is inserted into the second groove, and an electric push rod is fixedly connected to the movable plate in the first groove. A receiving block is fixedly connected to the electric push rod, and a V-shaped groove is provided on the upper end of the receiving block. By setting the receiving block and the V-shaped groove that can move up and down, the valve sleeve can be received, and the center point of the valve sleeve can be adjusted to correspond with the center point of the electric chuck.
[0009] As a preferred technical solution of this utility model, a pressure rod is in contact with one side of the movable plate. The pressure rod is threadedly connected to the operating table. By setting the pressure rod, the position of the movable plate can be fixed, and the contact position between the receiving block and the valve sleeve can be adjusted.
[0010] As a preferred technical solution of this utility model, the upper and lower sides of the movable plate are rotatably embedded with sliding balls, which contact the second groove. By setting the sliding balls, the friction of the movable plate movement is reduced.
[0011] As a preferred technical solution of this utility model, a circular groove is provided on one side of the skateboard, and a guide fan is provided in the circular groove. The circular groove corresponds to the position of the receiving block. By providing the guide fan, the V-shaped groove of the receiving block can be cleaned.

[0017] The present invention will be further described below with reference to the accompanying drawings.
[0018] Please refer to the following: Figure 1-3 The device shown is a grinding and testing device for an injector control valve sleeve, comprising an operating platform 1, a top plate 2, a limiting groove 3, a first motor, a lead screw 4, and a sliding plate 5. The top plate 2 can be connected to a grinding device to grind the valve sleeve. The first motor drives the lead screw 4 to rotate, causing the two sliding plates 5 to move relative to each other. A second motor is fixedly connected to the side of each sliding plate 5 that is far apart. The second motor drives a rotating drum 6 to rotate, which, in conjunction with an electric chuck 7, causes the valve sleeve to rotate. The programs for the first and second motors are built into the motors themselves. The output end of the second motor is fixedly connected to the rotating drum 6, and an electric chuck 7 is fixedly connected to one side of the rotating drum 6. The electric chuck 7 is driven by the motor, allowing it to engage or disengage. The materials, electric chuck 7 and top column 10 are paired. Electric telescopic rod 8 is fixedly connected inside the rotating drum 6. The extension and retraction of electric telescopic rod 8 can drive the top column 10 to extend from the central groove of electric chuck 7. The output end of electric telescopic rod 8 is fixedly connected to connecting plate 9. Top column 10 is fixedly connected to one side of connecting plate 9. Industrial camera 11 is fixedly connected to the center of the bottom end of top plate 2. Distance sensors are set on both sides of industrial camera 11. The distance sensors monitor the distance parameters on both sides of the circumference of valve sleeve, which can provide multi-point monitoring and improve detection accuracy. Then, industrial camera 11 is used to monitor the outer surface of valve sleeve, which can provide circumferential monitoring of valve sleeve. The position of industrial camera 11 corresponds to that of operating table 1.
[0019] The control panel 1 has a first groove 12, and two second grooves 13 are provided on both sides of the first groove 12. A movable plate 14 is inserted into the second groove 13. An electric push rod 15 is fixedly connected to the movable plate 14 in the first groove 12. A receiving block 16 is fixedly connected to the electric push rod 15. A V-shaped groove is provided on the upper end of the receiving block 16. By manually moving the movable plate 14, the position of the electric push rod 15 in the first groove 12 can be adjusted, changing the contact position between the two receiving blocks 16 and the valve sleeve.
[0020] The movable plate 14 has a pressure rod 17 in contact with one side. The pressure rod 17 is threaded to the operating table 1. By setting the pressure rod 17, the movable plate 14 can be squeezed by rotation.
[0021] The movable plate 14 has rotatably embedded sliders 18 on both its upper and lower sides. The sliders 18 contact the second groove 13. By setting the sliders 18, the friction of the movable plate 14 during movement is reduced.
[0022] The slide plate 5 has a circular groove on one side, and a guide fan 19 is installed in the circular groove. The circular groove corresponds to the position of the receiving block 16. By installing the guide fan 19, the V-shaped groove of the receiving block 16 can be cleaned as the slide plate 5 gradually approaches the receiving block 16.
[0023] Working principle: The guide fan 19 is activated to drive airflow to clean the V-groove of the receiving block 16. Then, during the valve sleeve grinding process, the first motor can be controlled to rotate the lead screw 4 and move the slide plate 5 relative to it. The extension of the electric push rod 15 can drive the receiving block 16 to move up and down, thereby ensuring that the central axis of the valve sleeve is consistent with the center point of the top column 10 or the electric chuck 7. Then, the valve sleeve is connected to the electric chuck 7 or the top column 10. Through the extension and contraction of the electric telescopic rod 8 and the retraction and extension of the electric chuck 7, the two ends of the valve sleeve contact the top column 10 or the electric chuck 7 respectively. After that, the second motor can drive the valve sleeve to rotate. The industrial camera 11 can provide monitoring of the outer surface of the valve sleeve, and the distance sensor provides monitoring of the distance between the valve sleeve and the camera. This reduces the need for two or more clamping operations during grinding, and after each clamping operation, it is necessary to detect and reposition whether the valve sleeve is at the center point of the valve sleeve, thus improving detection efficiency.
