Description

Technical Field

[0001] This invention relates to the field of fine needle processing, and more specifically to a method for processing fine needles. Background Technology

[0002] Currently, with the rapid development of cutting-edge industries such as aerospace, defense, microelectronics, modern medicine, and bioengineering in recent years, the demand for ultra-precision, complex, and micro-sized parts has become increasingly urgent. In the field of fine needle machining, the fine needle needs to be mounted on a chuck of an external rotating device. The chuck rotates at high speed, and the fine needle is processed while rotating. When machining fine needles with a diameter of less than 0.5 mm, the fine needle will vibrate to varying degrees relative to the chuck, resulting in unstable surface finish, chatter marks, and difficulty in controlling precision. Summary of the Invention

[0003] The main objective of this invention is to provide a method for processing fine needles to solve the problem of unstable needle surface finish caused by vibration of the fine needle relative to the chuck.

[0010] The step of clamping the end of the clamping section away from the processing section onto the chuck of the rotary device, and making the pasting area and the processing section extend outside the chuck, includes:

[0011] The end of the clamping segment away from the processing segment is clamped in the clamping space, and the pasting area and the processing segment extend out of the working end face;

[0012] The step of attaching the adhesive area to the chuck using shock-absorbing adhesive includes:

[0013] The shock-absorbing adhesive is adhered to the functional end face;

[0014] Push the damping adhesive toward the clamping space until the damping adhesive adheres to the adhesive area.

[0015] Preferably, the step of attaching the damping adhesive to the functional end face includes:

[0016] The damping adhesive is attached to the working end face in a ring shape, so that the damping adhesive is wrapped around the outer periphery of the fine needle;

[0017] The step of pushing the damping adhesive toward the clamping space until the damping adhesive adheres to the adhesive area includes:

[0018] The damping adhesive is pushed radially toward the clamping space until it adheres to the outer periphery of the adhesive area.

[0019] Preferably, the step of pushing the damping adhesive radially toward the clamping space until the damping adhesive is adhered to the outer periphery of the adhesion area includes:

[0020] The damping adhesive is simultaneously pushed from multiple different positions along its radial direction toward the clamping space until it adheres to the outer periphery of the adhesive area along the circumferential direction and completely covers the adhesive area; wherein the portion of the damping adhesive covering the outer periphery of the adhesive area forms a sleeve structure.

[0021] Preferably, the length of the sleeve structure along the extension direction of the fine needle is 3mm to 4mm, and the length of the sleeve structure is greater than or equal to the length of the adhesive area.

[0022] Preferably, the chuck includes a plurality of jaws, which are spaced apart circumferentially along the chuck. The inner ring surfaces of the plurality of jaws enclose the clamping space, and the outer end faces of the plurality of jaws form the working end faces. The clamping section includes an adhesive area and a clamping area that are connected to each other.

[0023] The step of clamping the end of the clamping segment away from the processing segment within the clamping space, and making the pasting area and the processing segment extend beyond the functional end face, includes:

[0024] The clamping area is extended into the clamping space;

[0025] Adjust the fine needle so that the position where the pasting area and the clamping area are connected is aligned with the working end face;

[0026] The multiple jaws move toward each other and clamp the clamping area, causing the pasting area and the processing section to extend beyond the working end face.

[0034] The chuck releases the clamping section, peels off the shock-absorbing rubber and the fine needle, and removes the shock-absorbing rubber and the fine needle from the chuck;

[0035] The fine needle is pulled out of the shock-absorbing rubber.

[0036] The fine needle processing method of this invention involves reserving an adhesive area on the clamping section near the processing section, extending the adhesive area beyond the chuck, and using shock-absorbing adhesive to bond the adhesive area to the chuck. This makes the connection between the fine needle and the chuck more secure and stable, preventing the fine needle from easily detaching from the chuck. The shock-absorbing adhesive also provides shock absorption and buffering, reducing vibration in the processing section, resulting in a more stable surface finish and preventing chatter marks on the surface of the processing section, thereby improving the processing accuracy of the fine needle.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0055] In this invention, the descriptions of directions such as "up," "down," "front," "back," "left," and "right" are as follows: Figure 7 The directions shown are for reference only and are used to interpret the location. Figure 7 The relative positional relationship between the components in the shown posture is such that if the specific posture changes, the directional indication will also change accordingly.

[0056] This invention provides a method for processing fine needles.

[0057] Reference Figure 1 This is a flowchart illustrating the first embodiment of the fine needle processing method of the present invention. The method includes the following steps:

[0058] Step S10: Provide a thin needle, which is divided into a clamping section and a processing section connected to each other along its extension direction; wherein, an adhesive area is reserved on the clamping section near the processing section;

[0059] Reference Figure 8The fine needle 10 extends in a left-right direction and is divided into a clamping section 11 and a processing section 12. The clamping section 11 is located to the right of the processing section 12. The clamping section 11 is used to clamp the fine needle 10 onto a rotating device so that the external rotating device can drive the fine needle 10 to rotate, thereby realizing various processing of the fine needle 10. A pasting area 112 is reserved on the clamping section 11 near the processing section 12, that is, a pasting area 112 is reserved at the left end of the clamping section 11. The pasting area 112 is not clamped by the chuck 20 of the rotating device.

[0060] Step S20: Clamp the end of the clamping section away from the processing section onto the chuck of the rotating device, and make the pasting area and the processing section extend out of the chuck;

[0061] Reference Figure 8 The external rotating device includes a chuck 20, which is used to clamp the fine needle 10 and drive it to rotate. The end of the clamping section 11 furthest from the processing section 12 is clamped onto the chuck 20 of the rotating device, i.e., the right end of the clamping section 11 is clamped onto the chuck 20, thus fixing the fine needle 10 onto the chuck 20. The processing section 12 extends beyond the chuck 20 to facilitate grinding or polishing processes on the processing section 12.

[0062] In this embodiment, the external rotating device can be an electric rotary dial machine. Electric rotary dial machines, as precision tools in precision mold processing, are widely used in the forming of fine needles 10. In other embodiments, the external rotating device can be any other device capable of clamping and rotating the fine needles 10. This invention does not limit the specific device used for the external rotating device.

[0063] Step S30: Use shock-absorbing adhesive to attach the pasting area to the chuck;

[0064] Reference Figure 7 By attaching the bonding area 112 to the chuck 20 with the damping adhesive 30, the connection between the fine needle 10 and the chuck 20 becomes stronger and more stable, making it less likely for the fine needle 10 to detach from the chuck 20. Furthermore, the damping adhesive 30 provides shock absorption and cushioning, reducing vibration in the machining section 12, resulting in a more stable surface finish and preventing chatter marks on the surface of the machining section 12, thereby improving the machining accuracy of the fine needle 10.

[0065] Step S40: Rotate the chuck and process the processing section.

[0066] The chuck 20 rotates at high speed, which drives the fine needle 10 to rotate. The processing section 12 performs processing during the rotation so that the fine needle 10 can complete the processing.

[0067] In this embodiment, the machining method for the fine needle 10 involves reserving an adhesive area 112 on the clamping section 11 near the machining section 12, extending the adhesive area 112 beyond the chuck 20, and using damping adhesive 30 to adhere the adhesive area 112 to the chuck 20. This makes the connection between the fine needle 10 and the chuck 20 more secure and stable, preventing the fine needle 10 from easily detaching from the chuck 20. The damping adhesive 30 also provides shock absorption and buffering, reducing vibration in the machining section 12, resulting in a more stable surface finish and preventing chatter marks on the surface of the machining section 12, thereby improving the machining accuracy of the fine needle 10.

[0068] Reference Figure 2 This is a flowchart illustrating a second embodiment of the fine needle processing method of the present invention. Based on the first embodiment described above, refer to... Figure 9 The chuck has a clamping space, and one end face of the chuck is the working end face;

[0069] A clamping space 22 is formed in the middle of the chuck 20, extending in the left-right direction. The clamping space 22 is used to accommodate the end of the clamping section 11 that is away from the processing section 12. The left end face of the chuck 20 is the working end face 23, and the shock-absorbing adhesive 30 is attached to the working end face 23.

[0070] Reference Figure 8 Step S20 includes:

[0071] Step S21: Clamp the end of the clamping segment away from the processing segment in the clamping space, and make the pasting area and the processing segment extend out of the working end face;

[0072] The end of the clamping section 11 furthest from the processing section 12 is clamped within the clamping space 22, thereby clamping the end of the clamping section 11 furthest from the processing section 12 onto the chuck 20 of the rotating equipment. The processing section 12 extends beyond the working end face 23 to facilitate grinding or polishing processes on the processing section 12. The adhesive area 112 extends beyond the working end face 23 to facilitate the bonding of the adhesive area 112 to the chuck 20 using the shock-absorbing adhesive 30.

[0073] Reference Figure 7 and Figure 8 Step S30 includes:

[0074] Step S31: Adhere the shock-absorbing adhesive to the functional end face;

[0075] First, attach the damping adhesive 30 to the working end face 23 to ensure a stable connection between the damping adhesive 30 and the working end face 23, and to prevent the damping adhesive 30 from detaching from the chuck 20.

[0076] Step S32: Push the damping adhesive toward the direction of the clamping space until the damping adhesive adheres to the adhesive area.

[0077] Push the shock-absorbing adhesive 30 to move it. The shock-absorbing adhesive 30 moves in the direction close to the clamping space 22 until the shock-absorbing adhesive 30 is attached to the adhesive area 112. Avoid applying too much force when directly applying the shock-absorbing adhesive 30 to the adhesive area 112, which could cause the fine needle 10 to break and injure the operator.

[0078] Reference Figure 3 This is a flowchart illustrating the third embodiment of the fine needle processing method of the present invention. Based on the second embodiment described above, and referring to... Figures 7 to 9 Step S31 includes:

[0079] Step S311: The damping adhesive is attached to the working end face in a ring shape, so that the damping adhesive is wrapped around the outer periphery of the fine needle;

[0080] The damping adhesive 30 is annularly bonded to the working end face 23, increasing the contact area between the damping adhesive 30 and the working end face 23. This makes the connection between the damping adhesive 30 and the working end face 23 more stable and reliable, improving the connection stability between the damping adhesive 30 and the chuck 20. Furthermore, the damping adhesive 30 is wrapped around the outer periphery of the fine needle 10, ensuring complete adhesion to the outer periphery of the fine needle 10. This allows the damping adhesive 30 to uniformly dampen vibrations in all directions of the fine needle 10, resulting in better damping effect and more stable surface finish of the machining section 12, thereby further improving the machining accuracy of the fine needle 10.

[0081] Step S32 includes:

[0082] Step S321: Push the damping adhesive radially toward the clamping space until the damping adhesive is adhered to the outer periphery of the adhesive area.

[0083] The damping adhesive 30 is pushed radially along its direction, moving towards the clamping space 22, i.e., from the periphery of the chuck 20 towards the clamping space 22, until it adheres to the outer periphery of the adhesion area 112. This ensures complete adhesion between the damping adhesive 30 and the outer periphery of the fine needle 10, allowing the damping adhesive 30 to uniformly dampen vibrations in all directions of the fine needle 10, thus improving the damping effect. Furthermore, the complete adhesion of the damping adhesive 30 to the outer periphery of the fine needle 10 makes the connection between the fine needle 10 and the chuck 20 more stable and reliable.

[0084] Reference Figure 4 This is a flowchart illustrating the fourth embodiment of the fine needle processing method of the present invention. Based on the third embodiment described above, and referring to... Figures 7 to 9 Step S321 includes:

[0085] Step S3211: Simultaneously push the damping adhesive from multiple different positions along the radial direction of the damping adhesive towards the clamping space until the damping adhesive is pasted along the circumference of the pasting area and completely covers the pasting area; wherein, the portion of the damping adhesive covering the outer periphery of the pasting area forms a sleeve structure.

[0086] The damping adhesive 30 is simultaneously pushed from multiple different positions along its radial direction towards the clamping space 22 to increase the bonding speed of the damping adhesive 30, thereby improving the processing efficiency of the fine needle 10. The damping adhesive 30 is bonded circumferentially to the outer periphery of the bonding area 112, completely covering the bonding area and increasing the bonding area between the damping adhesive 30 and the fine needle 10, resulting in a tighter and more reliable connection. The portion of the damping adhesive 30 covering the outer periphery of the bonding area 112 forms a sleeve structure, with the bonding area 112 located within the sleeve structure. By forming this sleeve structure, the damping adhesive 30 completely covers the entire outer periphery of the bonding area 112, enabling it to uniformly dampen the fine needle 10 in all directions.

[0087] Furthermore, the length of the sleeve structure along the extension direction of the fine needle 10 is 3mm to 4mm, and the length of the sleeve structure is greater than or equal to the length of the adhesive area 112.

[0088] The extension direction of the fine needle 10 is left-right, and the length of the sleeve structure in the left-right direction is 3mm to 4mm. If the length of the sleeve structure in the left-right direction is less than 3mm, the contact area between the damping adhesive 30 and the fine needle 10 is small, the damping effect of the damping adhesive 30 is poor, and the fine needle 10 will still vibrate to some extent, causing chatter marks on the surface of the processing section 12, affecting the processing accuracy of the fine needle 10. If the length of the sleeve structure in the left-right direction is greater than 4mm, the damping adhesive 30 may stick to the processing section 12, affecting the processing of the processing section 12; or the length of the pasting area 112 needs to be increased, but if the pasting area 112 extends too far beyond the working end face 23, it may cause greater vibration in the processing section 12. Therefore, the length of the sleeve structure in the extension direction of the fine needle 10 is 3mm to 4mm, which can make the damping effect of the damping adhesive 30 better. Furthermore, if the length of the sleeve structure is greater than or equal to the length of the pasting area 112, and the length of the sleeve structure is equal to the length of the pasting area 112, then the damping adhesive 30 will completely cover the entire outer periphery of the pasting area 112. If the length of the sleeve structure is greater than the length of the adhesive area 112, the sleeve structure extends into the clamping space 22, filling the gap between the claw 21 and the clamping area 111, making the connection between the claw 21 and the clamping area 111 tighter and more reliable.

[0089] In the preferred technical solution, the length of the sleeve structure along the extension direction of the fine needle 10 is 3mm to 3.5mm, which further improves the shock absorption effect of the damping rubber 30.

[0090] Reference Figure 5 This is a flowchart illustrating the fifth embodiment of the fine needle processing method of the present invention. Based on the second embodiment described above, the chuck includes multiple jaws, which are spaced apart circumferentially along the chuck. The inner ring surfaces of the multiple jaws enclose the clamping space, and the outer end faces of the multiple jaws form the working end faces. The clamping section includes the adhesive area and the clamping area that are connected to each other.

[0091] Reference Figure 8 and Figure 9 Multiple jaws 21 are spaced apart around the circumference of the chuck 20, and the inner ring surfaces of the multiple jaws 21 enclose a clamping space 22, thereby enabling the chuck 20 to have a clamping space 22. By forming a clamping space 22 with multiple jaws 21, the multiple jaws 21 cooperate to clamp the fine needle 10, making the force on the fine needle 10 more uniform and stable.

[0092] In this embodiment, there are three jaws 21. The three jaws 21 make the force on the fine needle 10 more even, and make the connection between the fine needle 10 and the chuck 20 more stable and reliable. In other embodiments, the number of jaws 21 can be flexibly adjusted to other numbers according to actual needs. The present invention does not limit the number of jaws 21.

[0093] Step S21 includes:

[0094] Step S211: Extend the clamping area into the clamping space;

[0095] Multiple jaws 21 move in opposite directions to open the clamping space 22, and the fine needle 10 moves to the right to extend the clamping area 111 into the clamping space 22.

[0096] Step S212: Adjust the fine needle so that the position where the pasting area and the clamping area are connected is aligned with the working end face;

[0097] Align the position of the adhesive area 112 and the clamping area 111 with the working end face 23 so that the clamping area 111 is entirely within the clamping space 22 and the adhesive area 112 extends out of the working end face 23 to facilitate the clamping claw 21 to clamp the clamping area 111 and the shock-absorbing adhesive 30 to adhere the adhesive area 112.

[0098] In step S213, the multiple jaws move toward each other and clamp the clamping area, causing the pasting area and the processing section to extend beyond the working end face.

[0099] Multiple jaws 21 move toward each other and cooperate to clamp the clamping area 111, thereby enabling the chuck 20 to clamp the fine needle 10.

[0100] Furthermore, the shock-absorbing adhesive 30 is Blu-Tack. Blu-Tack has a good shock-absorbing effect, and it can be installed without leaving any marks, avoiding the residue of adhesive on the fine needle 10. Blu-Tack is reusable, safe and environmentally friendly.

[0101] Step S40 includes:

[0102] Step S41: Rotate the chuck at a preset speed and grind the processing section with preset parameters.

[0103] Grinding is a micro-machining process that involves relative motion between the workpiece's surface and the grinding tool, applying pressure to remove tiny surface protrusions from the workpiece, resulting in very low surface roughness and high dimensional and geometric accuracy. Grinding is performed on machining section 12 according to preset parameters to reduce its surface roughness and improve its finish.

[0104] Step S41 includes:

[0105] In step S411, the chuck 20 is rotated at a speed of 2500 rpm to 3000 rpm, and the processing section 12 is ground at a grinding feed rate of 100 mm / min to 150 mm / min and a grinding accuracy of less than 0.002 mm.

[0106] The preset rotational speed of chuck 20 is 2500 rpm to 3000 rpm. Grinding time is inversely proportional to the rotational speed of chuck 20; the higher the rotational speed, the shorter the required grinding time. Therefore, to improve efficiency, a rotational speed of 2500 rpm or higher is needed. However, excessively high rotational speeds result in excessive energy consumption, which can cause the grinding equipment to shake. Furthermore, achieving higher rotational speeds places higher demands on the rotating shaft, increasing costs. Therefore, setting the rotational speed of chuck 20 to 2500 rpm to 3000 rpm ensures grinding efficiency while avoiding excessive energy consumption. Additionally, the preset parameters are a grinding feed rate of 100 mm / min to 150 mm / min and a grinding accuracy of less than 0.002 mm. Grinding the machining section 12 with a grinding feed rate of 100 mm / min to 150 mm / min can offset the resistance during feed, improve grinding efficiency, and ensure a grinding accuracy of less than 0.002 mm.

[0107] Reference Figure 6This is a flowchart illustrating the sixth embodiment of the fine needle processing method of the present invention. Based on the first embodiment described above, after step S40, the method further includes:

[0108] Step S50: Stop rotating the chuck;

[0109] The chuck 20 stops rotating, making it easy to remove the fine needle 10 and the shock-absorbing rubber 30.

[0110] Step S60: The chuck releases the clamping section, peels off the shock-absorbing rubber and the fine needle, and removes the shock-absorbing rubber and the fine needle from the chuck.

[0111] Step S70: The fine needle is pulled out of the shock-absorbing adhesive.

[0112] The chuck 20 releases its clamping section 11, thus releasing the fixation of the fine needle 10 and allowing it to be removed from the chuck 20. The damping rubber 30 and the fine needle 10 are then peeled off and removed together from the chuck 20. The fine needle 10 is then pulled out of the damping rubber 30. If the fine needle 10 is directly pulled out of the damping rubber 30 from the chuck 20, the operator's field of vision may be limited, reducing the efficiency of needle removal. Furthermore, after removing the damping rubber 30 and the fine needle 10 together from the chuck 20, the next fine needle 10 to be processed can be installed on the chuck 20, accelerating the production pace and improving production efficiency.

[0113] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural transformations made under the concept of the present invention using the description and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
