Description

Technical Field

[0001] This utility model relates to the field of needle valve body processing, and in particular to a novel grinding tool for the slender inner hole and seat surface of a needle valve body. Background Technology

[0002] In the field of precision machining, the needle valve body, as a core component of the fuel injection system, directly affects the fuel atomization effect, combustion efficiency, and operational stability of the engine due to the precision of its slender inner bore and seat surface. To ensure machining quality, the grinding process of the needle valve body requires real-time cooling and lubrication with cooling oil to reduce frictional heat during grinding, minimize defects such as burns and cracks on the workpiece surface, and extend the service life of the grinding wheel. However, during the grinding of the slender inner bore and seat surface of the needle valve body, the cooling oil tends to splash under high-pressure injection, which is difficult to control effectively. It often adheres to surrounding grinding rods, equipment guide rails, transmission components, and other equipment, polluting the machining environment and requiring time-consuming and labor-intensive cleaning.

[0003] Therefore, a new type of grinding tool is needed that can absorb and collect splashed cooling oil during the grinding process, preventing the cooling oil from adhering to the slender inner hole of the needle valve body and the seat surface of the other grinding rods or equipment. Utility Model Content

[0004] To overcome the shortcomings of the large amount of cooling oil splashing easily formed under high-pressure jet during the grinding of the slender inner hole and seat surface of the needle valve body, which is difficult to control effectively and often adheres to the surrounding grinding rod, equipment guide rail, transmission components and other equipment, the present invention provides a new type of grinding tool that can absorb and collect the splashed cooling oil during the grinding process, preventing the cooling oil from adhering to the slender inner hole and seat surface of the needle valve body on other grinding rods or equipment.

[0005] Technical Solution: A novel grinding tool for a needle valve body with a slender inner bore and seat surface, comprising a base, a chuck, a first rodless cylinder, a sliding frame, a slide rail, a moving frame, a second rodless cylinder, a sliding seat, a grinding rod, internal threads, an oil suction component, and a cleaning component. The base has a chuck on its right side, and the first rodless cylinder is connected inside the base. The sliding frame is connected to the slider of the first rodless cylinder. A slide rail is connected to the upper side of the base, and a moving frame is slidably connected to the slide rail. The moving frame is connected to the sliding frame, and the second rodless cylinder is connected to the middle of the moving frame. Both the second and first rodless cylinders are electrically connected to a processor via a control module. The sliding seat is connected to the slider of the second rodless cylinder. Grinding rods are located at both the front and rear of the sliding seat, with a through hole in the middle and internal threads on the inner right side of the grinding rod. Oil suction components capable of collecting splashed cooling oil are located at both the front and rear of the sliding seat, and cleaning components capable of removing grinding debris are located on the oil suction components.

[0006] Furthermore, it is particularly preferred that the sliding seat has connecting nozzles on both the front and rear left sides.

[0007] Furthermore, it is particularly preferred that the oil suction assembly includes guide rods, an oil suction frame, a protective net, and springs. The upper part of the sliding seat is slidably connected with two sets of guide rods, each set consisting of two guide rods. An oil suction frame is connected between the guide rods in the same set, and a protective net is connected to the outside of the oil suction frame. A spring is connected between each guide rod and the sliding seat.

[0008] In addition, it is particularly preferred that the outer side of the oil suction frame is provided with a docking nozzle.

[0009] In addition, it is particularly preferred that a cleaning assembly is also included, which includes a motor, gears, a rotating frame and cleaning brushes. The upper left part of the oil suction frame is connected to a motor, and the motor and the processor are electrically connected through a control module. Gears are connected to the output shaft of the motor. The middle part of the oil suction frame is rotatably connected to a rotating frame, and gears are also connected to the left side of the rotating frame. Adjacent gears mesh with each other. Cleaning brushes are connected to the front and rear sides of the rotating frame, and the cleaning brushes are in contact with the adjacent protective nets.

[0010] In addition, it is particularly preferred that the cleaning brush is made of nylon.

[0011] Beneficial effects: 1. When the grinding rod is pushed forward, the guide rod is squeezed and moves to the left, which drives the oil suction frame to move to the left. Then, the suction device generates suction in the collection hose, which allows the cooling oil to enter the oil suction frame through the protective net. The protective net blocks the grinding debris, thus achieving the effect of absorbing and collecting the splashed cooling oil during the grinding process and preventing the cooling oil from adhering to other grinding rods or equipment.

[0012] 2. The grinding rod of this utility model adopts a variable diameter structure, which increases its strength, reduces vibration during the grinding process, and ensures machining accuracy.

[0013] 3. This utility model starts the motor, drives the gears to rotate, and the meshing of the gears drives the rotating frame to rotate, which in turn causes the cleaning brush to rotate, thus achieving the effect of cleaning the abrasive attached to the protective net and preventing the protective net from clogging.

The sliding frame 4 is connected to the slider of the first rodless cylinder 3. The slide rail 5 is connected to the upper side of the base 1. The moving frame 51 is slidably connected to the slide rail 5 and is connected to the sliding frame 4. A second rodless cylinder 52 is connected to the middle of the first rodless cylinder 3. Both the second rodless cylinder 52 and the first rodless cylinder 3 are electrically connected to the processor through a control module. A sliding seat 6 is connected to the slider of the second rodless cylinder 52. Connecting nozzles are provided on the left side of both the front and rear parts of the sliding seat 6 to facilitate the injection of cooling oil. Grinding rods 7 are provided on both the front and rear parts of the sliding seat 6. A through hole 8 is opened in the middle of the grinding rod 7. An internal thread 9 is provided on the inner side of the right side of the grinding rod 7. Oil suction components are provided on both the front and rear parts of the sliding seat 6. Cleaning components are provided on the oil suction components.

[0022] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the oil suction assembly includes guide rods 10, oil suction frames 11, protective nets 12, and springs 17. The upper part of the sliding seat 6 is slidably connected with two sets of guide rods 10, each set consisting of two guide rods 10. The guide rods 10 in the same set are connected to the oil suction frames 11. The outer side of the oil suction frames 11 is provided with a docking nozzle to facilitate the external reception of the collection hose. The outer side of the oil suction frames 11 is connected to the protective nets 12. The guide rods 10 are connected to the sliding seat 6 with springs 17.

[0023] like Figure 4 and Figure 5 As shown, it also includes a cleaning assembly, which includes a motor 13, a gear 14, a rotating frame 15, and a cleaning brush 16. The upper left part of the oil suction frame 11 is connected to the motor 13. The motor 13 and the processor are electrically connected through a control module. The output shaft of the motor 13 is connected to the gear 14. The middle part of the oil suction frame 11 is rotatably connected to the rotating frame 15. The left side of the rotating frame 15 is also connected to the gear 14. Two adjacent gears 14 mesh with each other. The front and rear sides of the rotating frame 15 are connected to the cleaning brush 16. The cleaning brush 16 is in contact with the adjacent protective net 12. The cleaning brush 16 is made of nylon, which has good resistance and moderate softness, and will not scratch the surface of the protective net 12.

[0024] When using this utility model, first place the base 1 in the needle valve body processing area, then clamp and fix the needle valve body with the chuck 2, then connect the grinding wheel rod with the grinding rod 7, then rotate the grinding wheel rod so that the grinding wheel rod is moved and installed on the grinding rod 7 through the internal thread 9, then connect the cooling oil input hose through the connecting nozzle on the sliding seat 6, and then receive the collection hose through the connecting nozzle on the oil suction frame 11. Then the processor starts the first rodless cylinder 3 through the control module, which drives the sliding frame 4 to move, so that the moving frame 51 moves along the slide rail 5, which drives the grinding rod 7 to push towards the needle valve body. At the same time, the grinding rod 7 is driven to rotate by the drive device built into the sliding seat 6 to grind the inner hole of the needle valve body. When it is necessary to grind the seat surface of the needle valve body, the processor can start the second rodless cylinder 52 through the control module to drive the sliding seat 6 to move and quickly switch the grinding rod 7. The grinding rod 7 adopts a variable diameter structure, which increases its strength, reduces the vibration during the grinding process, and ensures the processing accuracy. During the advancement of the grinding rod 7, cooling oil is sprayed out through the through hole 8. This cooling oil cools the machined parts of the needle valve body and also promptly removes grinding debris and particles from the grinding wheel rod. As the grinding rod 7 advances, the guide rod 10 is compressed, causing it to move to the left. The spring 17 is compressed and contracts, moving the oil suction frame 11 to the left. Because cooling oil splashes during spraying, the suction device on the collection hose is activated, creating suction within the hose and forcing the cooling oil through the protective net 12 into the oil suction frame 11. The protective net 12 blocks the grinding debris, thereby absorbing and collecting the splashed cooling oil during the grinding process and preventing the cooling oil from adhering to the other grinding rods 7 or equipment. When the grinding rod 7 moves to the left, the spring 17 returns to its original position, driving the guide rod 10 to move and reset. When it is necessary to clean the grinding debris attached to the protective net 12, the motor 13 can be started to drive the gear 14 to rotate. The gears 14 mesh with each other, driving the rotating frame 15 to rotate, so that the cleaning brush 16 rotates, thereby cleaning the grinding debris attached to the protective net 12 and preventing the protective net 12 from becoming clogged.
