[0029] In this embodiment, the structure and working principle of a special grinder for oil needle are described in detail. The grinder mainly consists of a rack 1, a clamping mechanism 2 and a grinding assembly 3. The clamping mechanism 2 is the core part of the grinder, which includes a first driving unit 4 arranged on the rack 1. The driving shaft of this first driving unit 4 is designed with a plug-in slot 5, which is specially used for plugging the oil needle, and the plug-in slot 5 and the oil needle are clearance fit, so as to avoid the influence on the mounting seat 14 and the abutting piece 16, so as to ensure the accurate positioning of the oil needle in the grinding process.

[0030] In order to further fix the oil needle, a floating clamping assembly 6 is arranged on the driving shaft. The function of this floating clamping assembly 6 is to clamp the oil needle, so that the oil needle can rotate with the rotation of the floating clamping assembly 6, so as to realize the rotary grinding of the oil needle. This design not only improves the grinding accuracy, but also enhances the flexibility and safety of operation. Through this structure design, the special grinder for oil needle can efficiently and accurately complete the grinding work of the oil needle, meet the demand of high-precision machining, and make the driving shaft of the first driving unit 4 rotate coaxially with the oil needle in the process of driving the oil needle to rotate.

[0031] As shown in Figure 3 and Figure 4 , as a further technical solution, the floating clamping assembly 6 comprises:

[0032] The driving shaft on the first driving unit 4 is provided with two clamping shafts 7 in the Y-axis direction and two tensioning shafts 8 in the X direction;

[0033] It also includes a clamping plate 9 with two sliding grooves 10 and two tensioning grooves 11, the two sliding grooves 10 are respectively slidingly arranged on the two clamping shafts 7, and the two tensioning grooves 11 are respectively sleeved on the two tensioning shafts 8, the clamping plate 9 has an opening 12 which communicates with the two tensioning grooves 11, and the clamping plate 9 also has a clamping groove 13 located at the opening 12, one of the sliding grooves 10 is used to adjust the opening size of the opening 12 and the clamping groove 13 after sliding on one of the clamping shafts 7.

[0034] In this embodiment, the specific structure and working principle of the floating clamping assembly 6 of the oil needle special purpose grinding machine are described. The floating clamping assembly 6 includes two clamping shafts 7 arranged along the Y-axis direction and two tensioning shafts 8 arranged along the X direction, which are fixed on the driving shaft of the first driving unit 4. The clamping plate 9 has two sliding grooves 10 and two tensioning grooves 11, which are matched with the clamping shafts 7 and the tensioning shafts 8 respectively. The two sliding grooves 10 on the clamping plate 9 allow it to slide on the two clamping shafts 7, while the two tensioning grooves 11 are sleeved on the tensioning shafts 8 to ensure the stability of the clamping plate 9. The opening 12 of the clamping plate 9 is connected with the two tensioning grooves 11, and the design of the opening 12 allows the oil needle to float during rotation, so that the oil needle and the driving shaft rotate along the same axis. The clamping plate 9 is also provided with a clamping groove 13 located at the opening 12, which can adjust the opening size of the opening 12 and the clamping groove 13 after one sliding groove 10 slides on the clamping shaft 7, so as to realize the accurate clamping of the oil needle, so that the driving shaft of the first driving unit 4 rotates more coaxially with the oil needle during driving the oil needle to rotate. The oil needle can remain stable during grinding, while providing sufficient flexibility to adapt to oil needles of different specifications. By adjusting the position of the sliding groove 10, the opening size of the clamping groove 13 can be easily changed to adapt to oil needles of different diameters, ensuring accurate positioning and fixation of the oil needle during grinding. The design of this floating clamping assembly 6 not only improves the adaptability and operation convenience of the grinding machine, but also enhances the safety and efficiency of the grinding process.

[0035] As shown in Figure 1 and Figure 2 As a further technical solution, the clamping mechanism 2 also includes a mounting seat 14 arranged on the rack 1 behind the clamping plate 9 along the axis direction of the driving shaft of the first driving unit 4, the mounting seat 14 has a placing groove 15 for placing the oil needle, and a plurality of abutting pieces 16 are threaded through the mounting seat 14, which are used to abut against the bottom of the oil needle after being rotated.

[0036] In this embodiment, in order to improve the clamping stability and the convenience of operation of the oil needle, we add a mounting seat 14 on the rack 1 along the axis direction of the first driving unit 4 driving shaft, located after the clamping plate 9. The mounting seat 14 is designed with a placing groove 15, which is used to place the oil needle, ensuring the accurate positioning of the oil needle during grinding.

[0037] In order to further stabilize the oil needle, a plurality of abutting pieces 16 are threaded on the mounting seat 14. These abutting pieces 16 can be adjusted in position by rotating to abut the bottom of the oil needle. When the oil needle is placed in the placing groove 15, the operator can rotate the abutting pieces 16 to make them contact with the bottom of the oil needle and generate abutting force, thereby ensuring that the oil needle does not shift or rotate during grinding, improving the accuracy and efficiency of grinding. The fixed stability of the oil needle is enhanced, making the operation of the grinding machine more flexible and efficient. Through the optimization of this structure, the oil needle special grinding machine can better meet the high requirements of oil needle grinding accuracy in industrial production, and also improve the use convenience and application range of the equipment.

[0038] As shown in Figure 1 and Figure 2 , as a further technical solution, the clamping mechanism 2 further comprises:

[0039] The rack 1 is provided with a swing arm 17, and a telescopic piece 18 is arranged on the rack 1. The telescopic end of the telescopic piece 18 is arranged on the side of the swing arm 17 away from the rack 1. After the telescopic piece 18 is telescoped, it is used to drive the swing arm 17 to swing. A abutting wheel 19 is rotatably arranged on the swing arm 17 and used to abut the top end of the oil needle.

[0040] In this embodiment, a swing arm 17 is rotatably arranged on the rack 1. The swing arm 17 can swing around a fixed axis to adapt to oil needles of different lengths.

[0041] The telescopic piece 18 is used in cooperation with the swing arm 17. The telescopic piece 18 is arranged on the rack 1, and the telescopic end is located on the side of the swing arm 17 away from the rack 1. Through the telescoping action of the telescopic piece 18, the swing arm 17 can be driven to swing, thereby realizing dynamic abutment of the top end of the oil needle. This design allows the swing arm 17 to be adjusted according to the length and position of the oil needle, ensuring that the oil needle maintains the correct posture during grinding.

[0042] The swing arm 17 is also provided with a contact wheel 19 that is used to contact the top end of the oil needle. When the oil needle is placed in the placement slot 15 of the clamping plate 9 and the bottom is fixed by the abutting piece 16, the contact wheel 19 can be in contact with the top end of the oil needle, providing additional support and positioning. Not only does it improve the stability of the oil needle during grinding, but it also makes the entire clamping mechanism 2 adaptable to oil needles of different lengths and shapes, enhancing the versatility and applicability of the grinding machine.

[0043] As a further technical solution, one end of the abutting piece 16 for abutting the bottom of the oil needle is made of flexible material.

[0044] In this embodiment, the abutting piece 16 is designed with flexible material. Specifically, the end of the abutting piece 16 for abutting the bottom of the oil needle is made of flexible material, which can provide better adaptability and buffering effect. The choice of flexible material can be rubber or flexible metal, which has good elasticity and shape recovery ability, and can provide certain buffering when contacting the oil needle, reducing the impact of uneven or size differences in the bottom of the oil needle.

[0045] By using the abutting piece 16 made of flexible material, when the oil needle is placed in the placement slot 15 of the clamping plate 9, the abutting piece 16 can better adapt to the shape of the bottom of the oil needle, ensuring the stability of the oil needle during grinding. At the same time, the abutting piece 16 made of flexible material can also absorb part of the impact force generated during grinding, reducing damage to the oil needle and the grinding machine, improving the safety of processing and the processing quality of the oil needle. The application of this flexible material makes the clamping mechanism 2 more flexible and adaptable to a wider variety of oil needles, enhancing the versatility and applicability of the grinding machine.

[0046] As shown in Figure 1 and Figure 3 As a further technical solution, the rack 1 is arranged in a T shape, the rack 1 has a first end 20 and a second end 21, the clamping mechanism 2 and the polishing assembly 3 are respectively slidingly arranged on the first end 20 and the second end 21, the polishing assembly 3 includes a sliding seat 22 slidingly arranged on one end of the rack 1 and a polishing wheel 23 rotatingly arranged on the sliding seat 22, the sliding seat 22 is also provided with a second driving unit 24 for driving the polishing wheel 23 to rotate, and the sliding seat 22 is used to approach or move away from the clamping mechanism 2 after sliding on the second end 21.

[0047] In this embodiment, the rack 1 is arranged in a T shape to improve space utilization and operational flexibility. The rack 1 has a first end 20 and a second end 21, and the clamping mechanism 2 and the polishing assembly 3 are respectively slidingly arranged on the first end 20 and the second end 21. Such a layout design allows the distance between the clamping mechanism 2 and the polishing assembly 3 to be adjusted as needed, facilitating operation and maintenance.

[0048] The polishing assembly 3 comprises a sliding seat 22 which is slidingly arranged on the second end 21 of the rack 1 and is rotationally arranged with a polishing wheel 23. The polishing wheel 23 is designed to efficiently process the oil needle during grinding. In order to drive the rotation of the polishing wheel 23, a second driving unit 24 is further arranged on the sliding seat 22, which can provide the required power to keep the polishing wheel 23 at a stable rotating speed during work.

[0049] The design of the sliding seat 22 allows it to slide on the second end 21, thereby realizing the function of approaching or moving away from the clamping mechanism 2. This adjustable design allows the operator to flexibly adjust the distance between the polishing assembly 3 and the clamping mechanism 2 according to the length of different oil needles and grinding requirements, to ensure the best grinding effect. Through the T-shaped arrangement of the rack 1 structure, the oil needle special grinding machine not only improves the convenience of operation, but also enhances the overall stability and machining precision, providing a good foundation for efficient grinding of oil needles.

[0050] As shown in Figure 1 and Figure 3 , as a further technical solution, the polishing wheel 23 and the second end 21 are arranged at an angle of 60°.

[0051] In this embodiment, the polishing assembly 3 comprises a sliding seat 22 and a polishing wheel 23 rotationally arranged on the sliding seat 22, and the polishing wheel 23 is arranged at an angle of 60° with the second end 21 of the rack 1. This design allows the polishing wheel 23 to contact the oil needle at a more favorable angle during work, thereby improving the grinding efficiency and machining precision.

[0052] By arranging the polishing wheel 23 at an angle of 60°, it can better adapt to the conical or beveled features of the oil needle, which is particularly important for multi-cone processing of common rail oil needles. This arrangement can complete the processing of multiple cones based on one clamping, greatly improving the processing efficiency and ensuring the processing quality with good consistency. In addition, the 60° arrangement also helps to reduce vibration and noise during grinding, as the contact between the polishing wheel 23 and the oil needle is more stable, thereby improving the stability of the entire grinding process and the quality of the processed surface of the oil needle.

[0053] The above is only a preferred embodiment of the present application and does not limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
