[0061] Embodiment 1:

[0062] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 5 , the present embodiment provides a polishing device for needle machining, comprising:

[0063] a base 1;

[0068] The polishing mechanism 4 comprises:

[0069] The groove 41 is arranged on the top of the support plate 2;

[0070] The bracket 42 is arranged in the groove 41 of the support plate 2;

[0071] The motor one 43 is arranged between the two brackets 42;

[0072] The support shaft 44 is arranged on the output shaft of the motor one 43;

[0073] The fixing cylinder 45 is arranged on the support shaft 44;

[0074] The polishing shaft 46 is arranged in the fixing cylinder 45, and one end of the polishing shaft 46 extends out of the fixing cylinder 45 and is used for polishing the inner ring of the needle roller;

[0075] The connecting shaft 47 is arranged on the outer side of the lower end of the polishing shaft 46 in the axial direction;

[0076] The polishing grinding wheel 48 is arranged between the plurality of connecting shafts 47 and is used for polishing the outer ring of the needle roller.

[0077] In the technical solution, the base 1 provides a stable support platform for the entire device, the support plates 2 are arranged on the top of the base 1 on the left and right sides to ensure the stability of the overall structure of the device. The workbench 3 is slidingly arranged between the two support plates 2, which can be flexibly adjusted in position to conveniently adapt to the polishing requirements of different specifications of the needle roller and simultaneously support the needle roller. The fixing mechanism 5 is arranged on the workbench 3 and can be quickly adjusted and adapted according to the different sizes of the needle roller to stably fix the needle roller and ensure that the needle roller does not displace or shake during polishing, thereby providing protection for accurate polishing. The polishing mechanism 4 is arranged on the support plate 2 and is a core component for realizing polishing of the needle roller. The motor one 43 is installed between the two supports 42 to provide power for the entire polishing action. The support shaft 44 is connected to the output shaft of the motor one 43 to transmit the rotating power of the motor. The fixed cylinder 45 is installed on the support shaft 44 to protect and support the polishing shaft 46. The polishing shaft 46 is arranged inside the fixed cylinder 45 and extends out of the fixed cylinder 45 at one end and is specially used for polishing the inner ring of the needle roller. The plurality of connecting shafts 47 are arranged on the outer side of the lower end of the polishing shaft 46 in the axial direction and can stably support the polishing grinding wheel 48. The polishing grinding wheel 48 is used for polishing the outer ring of the needle roller. Through the cooperative work of the polishing shaft 46 and the polishing grinding wheel 48, the inner and outer rings of the needle roller are simultaneously polished.

[0078] Work flow: Place the needle roller on the workbench 3, adjust the fixing mechanism 5 on the workbench 3 according to the size of the needle roller to be polished, so that the needle roller can be stably fixed. Then turn on the motor one 43, the motor one 43 drives the support shaft 44 to rotate, and then the fixed cylinder 45 and the polishing shaft 46 installed in the fixed cylinder 45 rotate together, and the connecting shaft 47 connected with the polishing shaft 46 and the polishing grinding wheel 48 also start to rotate. Adjust the position of the workbench 3 to move the needle roller to the appropriate position under the polishing mechanism 4. At this time, the rotating polishing shaft 46 polishes the inner ring of the needle roller, and the rotating polishing grinding wheel 48 polishes the outer ring of the needle roller, realizing simultaneous polishing of the inner and outer rings. During the polishing process, the polishing speed can be controlled by adjusting the rotating speed of the motor one 43 according to the material of the needle roller, the precision requirement and other factors to achieve the best polishing effect. When the inner and outer rings of the needle roller are polished, stop the motor one 43, move the workbench 3 out from under the polishing mechanism 4, take out the polished needle roller, and complete the entire polishing work flow, thereby realizing synchronous polishing of the inner and outer rings to improve production efficiency, reduce production cost, and reduce equipment occupation space and resource waste.

[0079] As shown in Figure 2 and Figure 5 In the embodiment, the polishing grinding wheel 48 is hollow, the polishing shaft 46 is inside the polishing grinding wheel 48, and the polishing grinding wheel 48 and the polishing shaft 46 realize polishing of the inner and outer rings of the needle roller.

[0080] In the technical solution, the polishing wheel 48 is hollow, and the polishing shaft 46 is located inside the polishing wheel 48, and the two constitute a closely coordinated polishing assembly. When the device is running, the polishing shaft 46 finely polishes the inner ring of the needle roller by virtue of its high-speed rotation, and removes defects and unevenness on the surface of the inner ring; and the hollow polishing wheel 48 rotates synchronously around the polishing shaft 46 to carry out polishing work on the outer ring of the needle roller, so as to ensure that the smoothness and precision of the outer ring meet the standards, thereby realizing that the polishing of the inner and outer rings of the needle roller can be completed at one time of clamping, and the polishing efficiency and the consistency of the precision are greatly improved. The unique structure of the hollow polishing wheel and the built-in polishing shaft 46 ingeniously utilizes the space, and realizes multifunctional polishing in a limited device volume. Meanwhile, the structure can adapt to different specifications of needle rollers, and can flexibly cope with the processing needs of various needle rollers by adjusting the extension length of the polishing shaft 46, the size of the polishing wheel 48 and other parameters.

[0081] Work flow: According to the specific size of the needle roller to be polished, first, the fixing mechanism 5 on the workbench 3 is adjusted to ensure that the needle roller can be firmly and accurately fixed. The motor is started, and the motor drives the polishing shaft 46 to rotate at high speed. Since the polishing shaft 46 is connected to the polishing wheel 48 through a specific connecting structure, the polishing wheel 48 also rotates synchronously around the polishing shaft 46. The workbench 3 with the fixed needle roller is moved to the lower side of the polishing assembly, so that the needle roller accurately enters the polishing area. At this time, the high-speed rotating polishing shaft 46 acts on the inner ring of the needle roller to grind it; and the hollow polishing wheel 48 polishes the outer ring of the needle roller. During the polishing process, the operator can observe the polishing state in real time, and adjusts the motor speed according to the actual situation to meet the polishing needs at different stages. When the inner and outer rings of the needle roller reach the preset polishing precision, the motor is stopped, the workbench 3 is moved out of the polishing area, and the polished needle roller is taken out, and the whole polishing process is completed. The device breaks through the bottleneck of the prior art by designing the polishing wheel 48 as hollow and placing the polishing shaft 46 therein to construct an innovative polishing structure, realizing simultaneous polishing of the inner and outer rings of the needle roller, thereby improving the production efficiency, reducing resource consumption, and optimizing the overall processing process.

[0082] Embodiment 2:

[0083] The embodiment provides a polishing device for needle roller processing, which has the following technical features in addition to the technical solutions of the above-mentioned embodiments.

[0084] As shown in Figure 1 , Figure 3 and Figure 4 , in the embodiment, the optimized fixing mechanism 5 comprises:

[0085] The mounting groove 51 is opened on the left and right sides of the middle part of the workbench 3.

[0086] A guide groove 52 is arranged on the left and right sides of the bottom of the workbench 3, and the guide groove 52 is in communication with the mounting groove 51.

[0087] A guide rod 53 is arranged in the guide groove 52.

[0088] A sliding block 54 is slidingly arranged on the guide rod 53, and the sliding block 54 is slidingly connected with the guide groove 52.

[0089] A fixed shaft 55 is arranged on the top of the sliding block 54.

[0090] An arc-shaped clamping plate 56 is arranged on the fixed shaft 55, and the arc-shaped clamping plate 56 is used for clamping the rolling pin.

[0091] A reset spring 57 is sleeved on the guide rod 53 and arranged between the sliding block 54 and the workbench 3.

[0092] In the technical solution, the mounting groove 51 arranged on the left and right sides of the middle of the workbench 3 and the guide groove 52 arranged on the left and right sides of the bottom of the workbench 3 and in communication with the mounting groove 51 provide a stable mounting basis for the entire fixing mechanism 5. The guide rod 53 is arranged in the guide groove 52, and the sliding block 54 is slidingly arranged on the guide rod 53 and slidingly connected with the guide groove 52, so that the sliding block 54 can move along a precise path. The fixed shaft 55 is arranged on the top of the sliding block 54, and the arc-shaped clamping plate 56 is arranged on the fixed shaft 55. When the sliding block 54 moves, the arc-shaped clamping plate 56 can accurately approach or move away from the rolling pin. By virtue of the arc-shaped design, the arc-shaped clamping plate 56 closely fits the surface of the rolling pin, thereby achieving stable clamping of the rolling pin and preventing the rolling pin from deviating during polishing, so as to ensure polishing accuracy. Since the reset spring 57 is sleeved on the guide rod 53 and arranged between the sliding block 54 and the workbench 3, when it is necessary to fix rolling pins of different sizes, an operator can push the sliding block 54 by external force to overcome the elastic force of the reset spring 57, so that the distance between the arc-shaped clamping plates 56 changes, thereby adapting to the fixing requirement of rolling pins of different diameters. When the rolling pin is placed and the sliding block 54 is released, the elastic force of the reset spring 57 can automatically reset the sliding block 54, so as to drive the arc-shaped clamping plate 56 to tightly clamp the rolling pin, thereby achieving rapid and accurate self-adaptive adjustment.

[0093] Work flow: When the fixed needle is needed, first according to the preliminary judgment of the needle size, manually push the slider 54, make the slider 54 slide on the guide rod 53 along the guide groove 52. During the pushing process, the slider 54 will compress the reset spring 57, at this time the distance between the arc-shaped clamping plates 56 gradually increases. Place the needle in the appropriate position of the workbench 3, make sure the needle is between the two arc-shaped clamping plates 56. Loosen the slider 54, the reset spring 57 starts to stretch due to its own elastic force, pushes the slider 54 to move towards the needle, and then drives the fixed shaft 55 and the arc-shaped clamping plate 56 to move towards the needle. Finally, the arc-shaped clamping plate 56 closely fits the surface of the needle, and the needle is firmly clamped on the workbench 3. After the needle is fixed, the polishing device starts, and the inner and outer rings of the needle are polished according to the predetermined polishing process. During the polishing process, due to the stable clamping of the arc-shaped clamping plate 56, the needle will not shift or shake, ensuring the smooth progress and polishing accuracy.

[0094] But because the arc-shaped clamping plate 56 clamps the outer surface of the needle, the polishing shaft 46 smoothly polishes the inner ring of the needle, and the polishing wheel 48 can only polish the surface of the outer ring of the needle that is not clamped. After polishing is completed, the needle is taken out and rotated by one hundred and eighty degrees and placed on the workbench 3, and the turned needle is clamped by the arc-shaped clamping plate 56, and then the needle is polished again, so as to realize the polishing of the inner and outer rings of the needle as a whole.

[0095] When the polishing is completed, the slider 54 is manually pushed again to compress the reset spring 57, so that the distance between the arc-shaped clamping plates 56 increases, thereby loosening the clamping of the needle. At this time, the polished needle can be taken out from the workbench 3, completing the entire fixing and processing process and preparing for the next fixing and polishing of a new needle. In order to ensure the polishing accuracy and quality during the needle processing and polishing process, a reliable fixing mechanism 5 is provided to stably fix the needle so that it will not shift or shake during polishing. At the same time, the fixing mechanism 5 also needs to have the ability to quickly adapt to different sizes of needles to meet the diversified production needs and improve the processing efficiency.

[0096] Embodiment 3:

[0097] The embodiment provides a polishing device for needle processing, in addition to the technical solutions of the above-mentioned embodiments, further having the following technical features.

[0098] As shown in Figure 1 and Figure 3 , in this embodiment, the base 1 is provided with an adjusting mechanism 6 for adjusting the relative position of the clamped needle on the workbench 3 and the polishing wheel 48 and the polishing shaft 46, and the adjusting mechanism 6 comprises:

[0099] Motor two 61 is arranged on the left and right sides of the top of the base 1;

[0100] Ball screw 62, provided on the output shaft of motor two 61;

[0101] Slide plate 63, provided on the left and right sides of the workbench 3, the slide plate 63 is threadedly connected with the ball screw 62.

[0102] In the technical solution, the motor two 61 provided on the left and right sides of the top of the base 1 provides power source for adjustment. The ball screw 62 connected with the output shaft of the motor two 61 can efficiently and accurately convert the rotary motion of the motor into linear motion. The slide plate 63 provided on the left and right sides of the workbench 3 is threadedly connected with the ball screw 62. When the motor two 61 drives the ball screw 62 to rotate, the slide plate 63 will move linearly along the axial direction of the ball screw 62, thereby driving the workbench 3 and the roller pin fixed by the clamping mechanism 5 to adjust the position. By accurately controlling the rotation direction and rotation number of the motor two 61, the position of the roller pin can be accurately adjusted to the micron level, meeting various high-precision polishing requirements. Since the size, shape and polishing process requirements of the roller pin are different, the adjustment mechanism 6 can flexibly adjust the relative position of the roller pin, the polishing grinding wheel 48 and the polishing shaft 46 according to the actual situation. Whether it is to polish different diameter roller pins or to adjust the polishing angle according to the specific polishing process requirements, the adjustment mechanism 6 can quickly respond to ensure that the roller pin is always in the most suitable polishing position, improving the versatility and processing capacity of the equipment.

[0103] Work flow: Before the polishing operation, according to the specifications of the needle, polishing process requirements and other parameters, the control system sets the operating parameters of motor two 61, including the rotation direction, rotation speed and rotation number. Turn on motor two 61, motor two 61 starts to rotate according to the preset parameters, driving the ball screw 62 to rotate synchronously. With the rotation of the ball screw 62, the sliding plate 63 connected with the ball screw 62 starts to move along the axial direction of the screw, the movement of the sliding plate 63 drives the workbench 3 to adjust the position, and the needle clamped firmly by the fixing mechanism 5 on the workbench 3 also moves, gradually approaching or moving away from the polishing wheel 48 and the polishing shaft 46, until the best polishing position is reached. When the needle is adjusted to the appropriate position, stop the operation of motor two 61, start the polishing assembly (polishing shaft 46 and polishing wheel 48) of the polishing device, and polish the inner and outer rings of the needle according to the predetermined polishing process. During the polishing process, since the adjusting mechanism 6 has accurately adjusted the needle in place, the polishing assembly can accurately polish the needle, ensuring the polishing accuracy and quality. If the polishing effect of the needle is not ideal or the position of the needle needs to be adjusted during the process according to the process requirements, motor two 61 can be started again to fine-tune the motor parameters through the control system to adjust the position of the needle again, ensuring the smooth progress of the polishing work. When the needle polishing is completed, if it is necessary to replace the needle for the next processing, the workbench 3 and the needle can be moved to a position convenient for loading and unloading the needle by starting the adjusting mechanism 6 again, taking out the polished needle and putting in a new needle to be polished, and then adjusting the new needle to the appropriate polishing position through the adjusting mechanism 6 again to prepare for the next polishing operation. In this way, the position of the needle can be accurately controlled, the inner and outer rings of the needle can be accurately positioned at the best polishing position of the polishing assembly, ensuring the consistency and high precision of the polishing effect, improving the adaptability of the equipment to different processing tasks, and further improving the production efficiency.

[0104] Example 4:

[0105] The embodiment provides a polishing device for needle processing, which has the following technical features in addition to the technical solutions of the above-mentioned embodiments.

[0106] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 5 , in this embodiment, the polishing shaft 46 is connected to the fixed cylinder 45 through the locking mechanism 7, and the locking mechanism 7 comprises:

[0107] The fixed hole 71 is opened on the upper part of the polishing shaft 46;

[0108] The positioning hole 72 is opened on the fixed cylinder 45, and the fixed hole 71 and the positioning hole 72 are in communication;

[0109] Bolt 73, threaded into fixing hole 71 and positioning hole 72;

[0110] Nut 74, threaded onto bolt 73.

[0111] In this technical solution, during the processing and polishing of the needle, the polishing shaft 46 needs to be stably connected with the fixing cylinder 45 to ensure the accuracy and stability of the polishing operation. The locking mechanism 7 is provided to realize reliable and detachable connection between the polishing shaft 46 and the fixing cylinder 45, so as to ensure that the polishing shaft 46 does not displace or loosen during high-speed rotation, maintain stable operation of the entire polishing system, and facilitate disassembly and reassembly of the two during equipment maintenance and replacement of the polishing shaft 46.

[0112] The fixing hole 71 opened in the upper part of the polishing shaft 46 is in communication with the positioning hole 72 on the fixing cylinder 45. When the bolt 73 is threaded into the fixing hole 71 and the positioning hole 72 and fixed on the bolt 73 by the nut 74, the polishing shaft 46 can be tightly fixed in the fixing cylinder 45. This connection method utilizes the fastening force between the bolt 73 and the nut 74, effectively prevents the polishing shaft 46 from displacing radially or axially during high-speed rotation, and ensures that the polishing shaft 46 always maintains coaxial with the fixing cylinder 45 during operation, providing stable power transmission for precise polishing. By simply rotating the nut 74, the bolt 73 can be fastened and loosened. When the polishing shaft 46 needs to be maintained or replaced with different specifications to adapt to different polishing requirements, the operator can quickly unscrew the nut 74, remove the bolt 73, and then easily disassemble the polishing shaft 46 from the fixing cylinder 45; during installation, the reverse steps can be followed, which greatly improves the efficiency of equipment maintenance and adjustment.

[0113] Example 5:

[0114] The embodiment provides a polishing device for needle processing, which comprises the technical solutions of the above-mentioned embodiments and has the following technical features.

[0115] As shown in Figure 1 and Figure 3 In this embodiment, the optimized device further comprises a splash-proof mechanism 8, which comprises:

[0116] The buckle 81 is arranged on the fixing cylinder 45.

[0117] The protective cover 82 is arranged on the outer lower end of the buckle 81, and the protective cover 82 surrounds the polishing shaft 46 and the polishing grinding wheel 48.

[0118] The ear plate 83 is arranged on the front side of the two ends of the buckle 81.

[0119] The insertion hole 84 is arranged on the ear plate 83.

[0120] The insertion rod 85 is slidably positioned between the two insertion holes 84.

[0121] In this technical solution, during the needle roller grinding process, the grinding shaft 46 and the grinding wheel 48 rotate at high speed, generating a large amount of metal shavings and dust. If allowed to splash freely, this will not only pollute the working environment but may also threaten the safety of operators and even affect the normal operation of the equipment. The anti-splash mechanism 8 is designed to effectively block the shavings and dust generated during the grinding process, confining them within a certain range, creating a safe and clean working environment for operators, reducing damage to other parts of the equipment, and ensuring the continuous and stable operation of the grinding process.

[0122] The buckle 81 on the fixed cylinder 45 is used to fix the protective cover 82. The protective cover 82 surrounds the grinding shaft 46 and the grinding wheel 48, forming a closed space that effectively prevents metal chips and dust generated during the grinding process from flying outwards. Its special enclosure structure design ensures that when the grinding shaft 46 and the grinding wheel 48 rotate at high speed, no matter which direction the chips fly, they can be intercepted by the protective cover 82. The ear plates 83 at both ends of the front side of the buckle 81, and the insertion holes 84 opened on the ear plates 83, together with the insertion rod 85 slidably set between the two insertion holes 84, constitute a convenient opening and closing structure. When it is necessary to maintain or replace the grinding shaft 46 and the grinding wheel 48, or to place or remove the needle roller, the operator only needs to slide the insertion rod 85 out of the insertion hole 84 to easily open the protective cover 82; after the operation is completed, the insertion rod 85 is slid back into the insertion hole 84 to quickly close the protective cover 82, which is convenient, quick and easy and improves work efficiency.

[0123] like Figure 1 and Figure 3 As shown, in this embodiment, the support plate 2 is optimized to have an installation plate 9 on its outer side, and the bracket 42 is provided with a rotating shaft 91. The rotating shaft 91 is rotatably mounted on the installation plate 9, and the bracket 42 can rotate to facilitate the disassembly and replacement of the grinding shaft 46 and the grinding wheel 48.

[0124] In this technical solution, the mounting plate 9 on the outer side of the support plate 2 provides a stable support and rotational foundation for the bracket 42. The rotating shaft 91 on the bracket 42 is rotatably mounted on the mounting plate 9, allowing the bracket 42 to rotate around the shaft 91. When maintenance operations are required on the grinding shaft 46 and the grinding wheel 48, the operator can easily rotate the bracket 42 to move the grinding components to a convenient position, greatly improving the convenience of maintenance operations. By rotating the bracket 42 and moving the grinding shaft 46 and the grinding wheel 48 to the appropriate position, the operator can more easily access the relevant components, thus facilitating disassembly and replacement. This design avoids the problem of difficult operation due to limited component positions, effectively improving the efficiency and quality of equipment maintenance.

[0125] Work flow: When it is detected that the polishing shaft 46 or the polishing wheel 48 needs to be replaced due to wear or maintenance according to the regular maintenance plan, the operator first stops the operation of the polishing device and ensures that the device is in a safe and stationary state. The operator manually holds the support 42 and rotates the support 42 along the mounting plate 9 with the rotating shaft 91 as the center. During the rotation, the support 42 can be smoothly rotated due to the good rotating performance of the rotating shaft 91 until the polishing shaft 46 and the polishing wheel 48 are rotated to a position that is convenient for operation, such as a position close to the standing position of the operator and a position with a relatively open space for the operation of tools. After reaching the appropriate position, the operator uses the corresponding tools to disassemble the polishing shaft 46 and the polishing wheel 48 according to the correct disassembly process. For example, the nut 74 in the locking mechanism 7 is first unscrewed, the bolt 73 is removed, and the polishing shaft 46 is disassembled from the fixed cylinder 45. Then, the components connecting the polishing wheel 48 and the connecting shaft 47 are disassembled, and the polishing wheel 48 is removed. The operator takes out a new polishing shaft 46 and a new polishing wheel 48 that meet the specifications, and installs the polishing shaft 46 into the fixed cylinder 45 and fixes it with the locking mechanism 7 according to the installation requirements. Then, the polishing wheel 48 is installed on the connecting shaft 47 to ensure firm installation. After completing the replacement of the polishing shaft 46 and the polishing wheel 48, the operator holds the support 42 again and rotates it back to the initial working position to restore the polishing assembly on the support 42 to the normal working state. At this time, the device can be restarted to continue the polishing process of the needle roller. The polishing shaft 46 and the polishing wheel 48 are key vulnerable components of the needle roller polishing device, and they need to be disassembled and replaced due to wear and other reasons during long-term use. The traditional fixed installation method makes the disassembly and replacement operation difficult and time-consuming. The mounting plate 9 is arranged outside the support plate 2, and the support 42 is rotatably installed on the mounting plate 9 through the rotating shaft 91, which is designed to facilitate the disassembly and replacement of the polishing shaft 46 and the polishing wheel 48, improve the maintenance efficiency of the device, reduce the downtime of the device, and ensure the continuity of production.
