Description

Technical Field

[0001] This utility model relates to the field of oil outlet valve connector processing equipment, specifically an end face grinding device for oil outlet valve connectors. Background Technology

[0002] Oil outlet valve connectors are commonly used in fuel systems or hydraulic systems. The flatness of the end face directly affects the poor contact between the connector and the connecting parts, which may cause loosening or vibration, affecting the stability and safety of the system. The end face grinding device for oil outlet valve connectors is a device used to perform precision machining on the end face of the oil outlet valve connector. It aims to make the end face flat and smooth through the grinding process to ensure its sealing and connection reliability.

[0003] In the prior art, publication number "CN218081859U" discloses a device for grinding the end face of an oil outlet valve connector. This device includes a base, with a positioning seat fixedly connected to the upper surface of the base. A placement groove is formed on the upper surface of the positioning seat, and a discharge mechanism is installed at the bottom of the placement groove. The discharge mechanism includes a stop block, a fixing plate, a fixing rod, a guide groove, and a second spring. The guide groove is located at the bottom of the placement groove, the fixing rod is fixedly connected to the lower surface of the fixing plate, and the second spring is fixedly connected to the lower surface of the fixing plate. The bottom of the second spring is fixedly connected to the bottom of the placement groove. A pressing mechanism is installed above the positioning seat. With this structure, by setting the discharge mechanism, after the end face of the oil outlet valve connector is ground, the elastic force generated by the second spring can be used to eject the oil outlet valve connector, exposing a larger portion of it, thus facilitating its removal from the placement groove.

[0004] However, existing technologies still have significant shortcomings. Traditional devices can usually only clamp oil valve connectors one piece at a time, making it impossible to achieve batch clamping, resulting in low clamping efficiency. Furthermore, traditional devices use mechanical clamping methods such as jaws and clamps, which may cause scratches or indentations on the surface of the oil valve connector during the clamping process, affecting the surface quality of the workpiece. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By combining the workpiece positioning plate and the vacuum chuck, the oil outlet valve connector can be quickly placed on both sides of the vacuum chuck and fixed by adsorption. The vacuum chuck fixes the connector by negative pressure adsorption, avoiding scratches or indentations on the workpiece surface that may be caused by traditional mechanical clamping methods.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution:

[0023] Example 1: End face grinding device for oil outlet valve connector: The device includes a vacuum suction cup 2 on the top surface of a processing table 1. Workpiece positioning discs 3 are installed at the suction positions on both sides of the vacuum suction cup 2. The workpiece positioning discs 3 have mounting holes 4 arranged in a circular array on their sides. Control boxes 5 are located on both sides of the top surface of the processing table 1. Grinding discs 6 are located on the sides of the control boxes 5, with the vacuum suction cup 2 positioned between the two grinding discs 6. Both the grinding discs 6 and the workpiece positioning discs 3 are circular, and the center of the grinding discs 6 and the center of the vacuum suction cup 2 are on the same horizontal plane. The end face of the oil outlet valve connector typically needs to be ground smooth during processing to achieve a flat and smooth surface, ensuring reliable connection. The processing device... Table 1 is the workpiece processing platform, in which components such as vacuum chuck 2 and grinding disc 6 are located. Vacuum chuck 2, together with workpiece positioning disc 3, can fix the workpiece to be ground in the installation position by adsorption. Multiple mounting holes 4 in a circumferential array on workpiece positioning disc 3 can simultaneously place multiple oil valve connectors, realizing batch clamping and significantly improving clamping efficiency. The position and size of mounting holes 4 are precisely designed to ensure that oil valve connectors can be placed in the designated position quickly and accurately, reducing clamping time. The shape and size of mounting holes 4 on workpiece positioning disc 3 match the oil valve connector, ensuring that the connector is accurately positioned during clamping and improving processing accuracy.

[0024] It is worth noting that both sides of the vacuum suction cup 2 can be used to mount workpieces. By mounting and processing on both sides, the space of the equipment is fully utilized, improving the utilization rate of the equipment. Simultaneous processing on both sides reduces the idle time of the equipment and improves production efficiency. A vacuum pump is added to the vacuum suction cup 2 and connected to the vacuum suction cup 2 through a hose. The vacuum suction cup 2 generates negative pressure, which is a pressure lower than atmospheric pressure, through the vacuum pump. A sealed space is formed between the suction surface of the suction cup and the surface of the oil outlet valve connector. Due to the negative pressure, atmospheric pressure firmly presses the oil outlet valve connector onto the suction surface of the suction cup, achieving adsorption and fixation. The suction surface of the suction cup is usually equipped with a sealing ring such as rubber or silicone to ensure a good seal between the suction surface and the workpiece surface, prevent gas leakage, and maintain a stable negative pressure state. The workpiece positioning plate 3 is provided with mounting holes 4 that match the shape and size of the oil outlet valve connector, ensuring that the connector can be accurately placed in the designated position. The design of the positioning component ensures that the oil outlet valve connector is accurately positioned during clamping, avoiding offset or tilting. The workpiece positioning plate 3 and both sides of the vacuum suction cup 2 can be connected and fixed by flanges or bolts, etc., which facilitates replacement according to the size of the workpiece later.

[0025] Example 2:

[0026] Based on Embodiment 1, the top surface of the processing table 1 is provided with a lead screw 8 and a limiting rod 9, and the bottom surface of the vacuum suction cup 2 is connected to a support base 10. The support base 10 is sleeved on the surface of the lead screw 8 and the limiting rod 9. The limiting rod 9 is located on both sides of the lead screw 8, and the positions of the limiting rod 9 and the lead screw 8 are directly below the vacuum suction cup 2. The support base 10 is threadedly connected to the surface of the lead screw 8. To further explain, the addition of a lead screw 8 and a limiting rod 9 to the top surface of the processing table 1, and the connection of a servo motor to one end of the lead screw 8 for driving the lead screw 8 to rotate, and the positions of the lead screw 8 and the limiting rod 9 being directly below the vacuum suction cup 2, ensures that the positions of the lead screw 8 and the limiting rod 9 will not affect the workpiece grinding operation. The support base 10 is used to connect the lead screw 8 to the vacuum suction cup 2. When the lead screw 8 rotates, it cooperates with the limiting rod 9 to limit the support base 10, thereby completing the linear movement of the vacuum suction cup 2.

[0027] The control box 5 houses a grinding motor 7, whose rotating end is connected to the center of the grinding disc 6. After the workpiece is adsorbed and fixed, the vacuum suction cup 2 moves linearly along the top surface of the processing table 1, moving the workpieces on both sides to the position of the grinding disc 6, making them flush. The lateral position of the grinding disc 6 is adjusted so that it is located at the grinding end face of the workpiece. Starting the grinding motor 7 allows for grinding multiple workpieces. Lateral adjustment cylinders 12 are installed on both sides of the processing table 1. Fixed brackets 13 are fitted onto the surface of the lateral adjustment cylinders 12, and one end of the fixed brackets 13 is screwed to the side of the processing table 1. The grinding motor 7 is located inside the control box 5, and the grinding disc 6 is connected to the grinding motor. The rotating end of 7 is connected. Since the horizontal adjustment cylinders 12 on both sides of the processing table 1 are connected and fixed by the fixed bracket 13, when the extension end of the horizontal adjustment cylinder 12 works, it can drive the control box 5 and grinding disc 6 and other components to move horizontally on the processing table 1, and complete the distance adjustment between the grinding disc 6 and the workpiece. The top surface of the processing table 1 is provided with slide rails 11, and the sliding end of the bottom surface of the control box 5 is located inside the slide rail 11. The extension end of the horizontal adjustment cylinder 12 is connected to the control box 5. It is necessary to note that in order to ensure that the control box 5 can move horizontally accurately, slide rails 11 are added on both sides of the top surface of the processing table 1 so that the control box 5 can be adjusted along the slide rail 11 when moving horizontally.

[0028] Working Principle: The end face of the oil outlet valve connector usually needs to be ground flat during processing to achieve a smooth and flat surface, ensuring reliable connection. The processing table 1 of the device is the platform for workpiece processing, where components such as the vacuum suction cup 2 and the grinding disc 6 are located. The vacuum suction cup 2, in conjunction with the workpiece positioning disc 3, can fix the workpiece to be ground in the installation position by adsorption. Multiple mounting holes 4 in a circumferential array on the workpiece positioning disc 3 can simultaneously place multiple oil outlet valve connectors, achieving batch clamping and significantly improving clamping efficiency. The position and size of the mounting holes 4 are precisely designed to ensure that the oil outlet valve connector can be placed quickly and accurately in the designated position, reducing clamping time. Both sides of the vacuum suction cup 2 can be used to install workpieces. Through double-sided installation and processing, the workpiece is adsorbed and fixed, and then the vacuum... The suction cup 2 moves linearly along the top surface of the processing table 1, moving the workpieces on both sides to the position of the grinding disc 6, making them level. The lateral position of the grinding disc 6 is adjusted so that it is located at the grinding end face of the workpiece. The grinding motor 7 is started to grind multiple sets of workpieces. The grinding motor 7 is located inside the control box 5. The grinding disc 6 is connected to the rotating end of the grinding motor 7. Since the lateral adjustment cylinders 12 on both sides of the processing table 1 are connected and fixed by the fixed brackets 13, when the extension end of the lateral adjustment cylinders 12 is working, it can drive the control box 5 and the grinding disc 6 and other components to move laterally on the processing table 1, completing the adjustment of the distance between the grinding disc 6 and the workpiece. It is worth noting that in order to ensure that the control box 5 can move laterally accurately, slide rails 11 are added on both sides of the top surface of the processing table 1, so that the control box 5 can be adjusted along the slide rails 11 when moving laterally.
