[0049] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0050] like Figure 1-3 As shown, a high-precision shaft grinding tooling includes:

[0051] Base;

[0052] A longitudinal moving component, the longitudinal moving component is movably mounted on the base, and the longitudinal moving component is suitable for longitudinal linear movement relative to the base;

[0053] Lateral movement components, the lateral movement components include:

[0054] A transverse moving guide rail 31, wherein the transverse moving guide rail 31 is mounted on the base;

[0055] Two transverse moving positioning support assemblies 32, the transverse moving positioning support assemblies 32 are slidably mounted on the transverse moving guide rail 31;

[0056] A transversely movable axial positioning support assembly 33, wherein the transversely movable axial positioning support assembly 33 is slidably mounted on the transversely movable guide rail 31;

[0057] Two positioning components, the positioning components are movably mounted on the transverse movable positioning support component 32, and the positioning components include a horizontal positioning component 41 and a vertical positioning component 42;

[0058] The horizontal positioning assembly 41 is adapted to be actuated to adjust the horizontal position of the axis of the workpiece 10 abutted against the horizontal positioning assembly 41;

[0059] The vertical positioning assembly 42 is adapted to be actuated to adjust the vertical position of the axis of the workpiece 10 abutted against the vertical positioning assembly 42;

[0060] An axial positioning assembly, which is movably mounted on the transversely movable axial positioning support assembly 33, and is adapted to be moved to abut against the end surface of the workpiece 10 to locate the axial position of the workpiece 10;

[0061] The driving device is installed on the longitudinal moving assembly, and the driving device is suitable for abutting against the outer surface of the workpiece 10 and driving the workpiece 10 to rotate around the axis.

[0062] In this embodiment, if Figure 2-3 As shown, the workpiece 10 is mainly for stepped shafts or optical shafts that require high coaxiality grinding. When using a high-precision shaft grinding tool, first adjust the position of the lateral moving positioning support assembly 32 and the lateral moving axial positioning support assembly 33 to provide a suitable position for placing the workpiece 10. Subsequently, the workpiece 10 is placed on the vertical positioning assembly 42 of the lateral moving positioning support assembly 32. By finely adjusting the vertical positioning assembly 42, the vertical position of the axis of the workpiece 10 can be accurately determined to ensure that the vertical position of the axis of the workpiece 10 is aligned during the processing. At the same time, by adjusting the horizontal positioning assembly 41, the horizontal position of the axis of the workpiece 10 is further determined to ensure that the coaxiality requirements of the workpiece 10 are met.

[0063] Next, by adjusting the lateral movement of the axial positioning support assembly 33, the axial positioning assembly is used to abut against the end face of the workpiece 10 to limit the axial position of the workpiece 10. Finally, the drive device is moved by the longitudinal movement assembly, and the drive device is used to press the workpiece 10 and drive the workpiece 10 to rotate. The whole process ensures the position accuracy and rotation accuracy of the workpiece 10 during the processing, and improves the processing accuracy.

[0064] In some embodiments, the number of the laterally movable positioning support assembly 32 and the positioning assembly is not limited to two and can be set according to specific needs.

[0065] Specifically, Figure 1 As shown, the longitudinal moving component can be the following structure, including:

[0066] A longitudinal guide rail 21, the longitudinal guide rail 21 is fixed on the base, and the longitudinal guide rail 21 extends along the longitudinal direction of the base;

[0067] A longitudinal movable slider 22, the longitudinal movable slider 22 is movably mounted on the longitudinal guide rail 21;

[0068] The driving device is mounted on the longitudinal moving slide 22 .

[0069] In this embodiment, if Figure 1-2 As shown, the arrangement of the longitudinal guide rail 21 and the longitudinal movable slider 22 can realize the smooth movement of the driving device along the longitudinal direction of the base, so that the driving device can abut against the outer surface of the workpiece 10 of different coarseness and fineness, drive the workpiece 10 to rotate, so as to perform grinding on the workpiece 10.

[0070] During use, the longitudinal movable slider 22 can be slid to a suitable position first, and then the workpiece 10 can be driven to rotate at a low speed by the driving device.

[0071] Specifically, Figure 1 and Figure 3 As shown, the longitudinal moving slider 22 is also provided with a longitudinal moving limit screw 34 which is connected to the longitudinal moving slider 22 by threads;

[0072] The longitudinal movement limiting screw 34 is adapted to be screwed against the base to limit the sliding position of the longitudinal movement slider 22 relative to the longitudinal guide rail 21 .

[0073] In this embodiment, if Figure 1 and Figure 3 As shown, the longitudinal movement limit screw 34 is threadedly connected to the longitudinal movement slider 22. By screwing the longitudinal movement limit screw 34, the end of the longitudinal movement limit screw 34 can be pressed against the base, thereby limiting the longitudinal movement slider 22 from continuing to move along the longitudinal guide rail 21, thereby playing a role of limiting and fixing.

[0074] During use, when the longitudinal movable slider 22 is moved to a desired suitable position, the longitudinal movable limit screw 34 is tightened to make it abut against the base, so that the longitudinal movable slider 22 can be fixed at the position to prevent it from being displaced due to vibration and other reasons during the processing, thereby ensuring the accuracy of the processing position. When it is necessary to move to another position for processing, the longitudinal movable limit screw 34 is first loosened, and then the longitudinal movable slider 22 is moved.

[0075] The longitudinal movement limit screw 34 can be a manually tightened screw, which is simple and convenient to operate. It can also be a spring-loaded latch or a knob with a handle or other fastener forms.

[0076] In order to accurately control the tightness of the longitudinal movement limit screw 34, a graduated adjustment nut can be provided on the longitudinal movement limit screw 34. The extension length of the longitudinal movement limit screw 34 can be controlled by adjusting the nut, thereby accurately controlling the force with which the screw presses against the base, which can both reliably limit and fix the screw and prevent damage to components due to over-tightening.

[0077] In addition, a countersunk hole or threaded hole that cooperates with the longitudinal movement limit screw 34 can be opened on the base, so that the end of the longitudinal movement limit screw 34 can be inserted or screwed into the base instead of against the base surface, which can improve the reliability and repeatability of the limit positioning.

[0078] In some embodiments, a plurality of longitudinal movement limit screws 34 may be provided and distributed at different positions of the longitudinal movement slider 22 , so as to further improve the positioning accuracy and reliability of the longitudinal movement slider 22 through multi-point limiting.

[0079] Specifically, Figure 2 As shown, both the lateral movement positioning support assembly 32 and the lateral movement axial positioning support assembly 33 are provided with lateral movement limiting assemblies suitable for limiting the sliding positions of the lateral movement positioning support assembly 32 and the lateral movement axial positioning support assembly 33 relative to the lateral movement guide rail 31;

[0080] The lateral movement limiting assembly includes a lateral movement limiting screw 35, which is connected to the corresponding lateral movement positioning support assembly 32 and the lateral movement axial positioning support assembly 33 through threads;

[0081] The lateral movement limiting screw 35 is suitable for abutting against the lateral movement guide rail 31 by being screwed, so as to limit the sliding position of the lateral movement positioning support assembly 32 and the lateral movement axial positioning support assembly 33 relative to the lateral movement guide rail 31 .

[0082] In this embodiment, if Figure 2As shown, both the lateral movement positioning support assembly 32 and the lateral movement axial positioning support assembly 33 can slide along the lateral movement guide rail 31, and by arranging lateral movement limiting assemblies on them, they can be conveniently locked in the required positions.

[0083] The lateral movement limiting screw 35 is a common limiting fastener, which is respectively arranged on the lateral movement positioning support assembly 32 and the lateral movement axial positioning support assembly 33 through threaded connection. When it is necessary to fix the lateral movement positioning support assembly 32 and the lateral movement axial positioning support assembly 33 at a certain position, the lateral movement limiting screw 35 is screwed so that its end abuts against the lateral movement guide rail 31, thereby limiting the lateral movement positioning support assembly 32 and the lateral movement axial positioning support assembly 33 from continuing to slide on the lateral movement guide rail 31.

[0084] During use, first loosen the lateral movement limit screw 35, move the lateral movement positioning support assembly 32 and the lateral movement axial positioning support assembly 33 to the desired position, and then tighten the lateral movement limit screw 35 to reliably fix them at the target position on the lateral movement guide rail 31. When the position needs to be adjusted, loosen the lateral movement limit screw 35 again, and slide the lateral movement positioning support assembly 32 and the lateral movement axial positioning support assembly 33.

[0085] Specifically, Figure 2-3 As shown, the horizontal positioning assembly 41 is provided with a horizontal waist-shaped hole extending in the horizontal direction;

[0086] The lateral movable positioning support assembly 32 is provided with a first mounting threaded hole corresponding to the horizontal waist-shaped hole;

[0087] The horizontal positioning assembly 41 is suitable for being connected to the first mounting threaded hole through the horizontal waist-shaped hole by a first fastener so as to be installed on the lateral movement positioning support assembly 32 .

[0088] In this embodiment, if Figure 2-3 As shown, the setting of the horizontal waist-shaped hole allows the horizontal positioning component 41 to adjust its position in the horizontal direction within a certain range. When the horizontal position of the workpiece 10 needs to be adjusted, the first fastener is first loosened so that the horizontal positioning component 41 can slide along the horizontal waist-shaped hole on the lateral movable positioning support component 31. After the workpiece 10 is adjusted to a suitable horizontal position, the first fastener is then tightened to lock the horizontal positioning component 41 on the lateral movable positioning support component 31, thereby fixing the workpiece 10 at the target horizontal position.

[0089] The length of the horizontal waist-shaped hole determines the horizontal adjustment range of the horizontal positioning assembly 41. The width of the horizontal waist-shaped hole generally matches the diameter of the first fastener, but larger circular holes can be opened at both ends of the horizontal waist-shaped hole to facilitate the insertion and extraction of the first fastener.

[0090] The first fastener can be selected from common fasteners such as bolts and screws. For the convenience of quick assembly and disassembly, quick-change fasteners such as quick-locking screws with handles and spring pins can also be used.

[0091] In some embodiments, a positioning pin and a positioning hole for use in conjunction may be provided between the horizontal waist-shaped hole and the first mounting threaded hole. When the horizontal positioning component 41 slides along the horizontal waist-shaped hole to a specific position, the positioning pin may be inserted into the positioning hole to achieve accurate positioning of the horizontal positioning component 41 relative to the lateral movement positioning support component, thereby improving positioning efficiency and repeatability.

[0092] In addition, the contact surface between the horizontal positioning assembly 41 and the workpiece 10 can be made of a material with elasticity or vibration-damping properties, such as a rubber pad, to reduce vibration and impact during the grinding process and improve the quality of the machined surface.

[0093] Specifically, Figure 2-3 As shown, the vertical positioning assembly 42 is provided with a vertical waist-shaped hole extending in the vertical direction;

[0094] The lateral movable positioning support assembly 32 is provided with a second mounting threaded hole corresponding to the vertical waist-shaped hole;

[0095] The vertical positioning assembly 42 is suitable for being connected to the second mounting threaded hole through the vertical waist hole by a second fastener so as to be installed on the lateral movement positioning support assembly 32 .

[0096] In this embodiment, if Figure 1-3 As shown, the vertical waist-shaped hole allows the vertical positioning component 42 to adjust its position in the vertical direction within a certain range. When the vertical position of the workpiece 10 needs to be adjusted, the second fastener is first loosened to allow the vertical positioning component 42 to slide along the vertical waist-shaped hole on the lateral movable positioning support component 32. After the workpiece 10 is adjusted to a suitable vertical position, the second fastener is then tightened to lock the vertical positioning component 42 on the lateral movable positioning support component, thereby fixing the workpiece 10 at the target vertical position.

[0097] The length of the vertical waist-shaped hole determines the vertical adjustment range of the vertical positioning assembly 42. Similar to the horizontal waist-shaped hole, the width of the vertical waist-shaped hole generally matches the diameter of the second fastener, but larger circular holes can be opened at both ends of the vertical waist-shaped hole to facilitate the insertion and extraction of the second fastener.

[0098] The second fastener may be a common fastener such as a bolt or a screw similar to the first fastener, or a quick-change fastener such as a quick-locking screw or a spring pin to improve the adjustment efficiency.

[0099] In some embodiments, a positioning pin and a positioning hole for use in conjunction may be provided between the vertical waist-shaped hole and the second mounting threaded hole. When the vertical positioning assembly slides to a specific position along the vertical waist-shaped hole, the positioning pin may be inserted into the positioning hole to achieve precise positioning of the vertical positioning assembly relative to the lateral movement positioning support assembly, thereby improving positioning efficiency and repeatability.

[0100] In addition, the contact surface between the vertical positioning assembly 42 and the workpiece 10 may also be made of a material with elasticity or vibration-damping properties, such as a rubber pad, to reduce vibration and impact during the grinding process and improve the quality of the machined surface.

[0101] Specifically, Figure 2-3 As shown, the axial positioning assembly includes an axial positioning block 51 and a locking nut 52;

[0102] The axial positioning block 51 is provided with an abutting surface abutting against the end surface of the workpiece 10, and a mounting surface opposite to the abutting surface;

[0103] The mounting surface is provided with mounting threaded holes;

[0104] The lateral movement axial positioning support assembly 33 is provided with a threaded through hole corresponding to the mounting threaded hole;

[0105] The locking nut 52 passes through the threaded through hole and is connected to the axial positioning block 51 . The locking nut 52 is suitable for locking the axial positioning block 51 at a predetermined position on the transversely movable axial positioning support assembly 33 .

[0106] In this embodiment, if Figure 2-3 As shown, there are two important surfaces on the axial positioning block 51: one is the abutting surface abutting against the end face of the workpiece 10, which is used for axial positioning of the workpiece; the other is the mounting surface opposite to the abutting surface, and a mounting threaded hole is provided on the mounting surface, which is used to install the axial positioning block 51 on the laterally movable axial positioning support assembly 33.

[0107] A threaded through hole corresponding to the mounting threaded hole is provided on the lateral movement axial positioning support assembly 33. The locking nut 52 passes through the threaded through hole and is threadedly connected with the mounting threaded hole on the axial positioning block 51. By screwing the locking nut 52, the axial positioning block 51 can be firmly locked at a predetermined position on the lateral movement axial positioning support assembly 33.

[0108] When in use, firstly, the axial positioning block 51 is passed through the threaded through hole on the transversely movable axial positioning support assembly 33, and its abutting surface is abutted against the end surface of the workpiece 10. Then, the locking nut 52 is rotated to make it fully contact with the mounting threaded hole on the axial positioning block 51 and tightened, thereby locking the axial positioning block 51 on the transversely movable axial positioning support assembly 33. In this way, the axial position of the workpiece 10 is fixed and will not move axially during the grinding process. The abutting surface can also be made of a material with buffering or vibration reduction properties, such as rubber, to reduce vibration and impact during the grinding process.

[0109] Specifically, Figure 1-2 As shown, the driving device includes a driving source 61 and a pressure wheel 62;

[0110] The driving source 61 is slidably mounted on the transversely movable axial positioning support assembly 33, and a driving shaft is provided on the driving source 61;

[0111] The pressure wheel 62 is installed on the shaft end of the driving shaft, and the wheel surface of the pressure wheel 62 is perpendicular to the axis of the driving shaft;

[0112] When the driving source 61 drives the driving shaft to rotate, the pressure wheel 62 is adapted to abut against the outer surface of the workpiece and drive the workpiece 10 to rotate.

[0113] Specifically, the driving source 61 is a speed-regulating motor.

[0114] In this embodiment, if Figure 1-3 As shown, when in use, the driving source 61 is first slid to a suitable position by laterally moving the axial positioning support assembly 33 so that the pressure wheel 62 contacts the outer surface of the workpiece 10. Then, the driving source 61 is started, the driving shaft starts to rotate, and the pressure wheel 62 rolls and drives the workpiece 10 to rotate. By controlling the rotation speed and direction of the driving source 61, the rotation speed and direction of the workpiece 10 can be adjusted.

[0115] During use, taking the stepped shaft as an example, first fix the transverse moving guide rail 31 on the base, and then adjust the two transverse moving positioning support components 32 and one transverse moving axial positioning support component 33 according to the length of the workpiece 10 and the support position of the stepped shaft. After the position is adjusted, use the transverse moving limit screw 35 to lock the transverse moving positioning support component 32 on the transverse moving guide rail 31. Then, adjust the horizontal positioning component 41 and the vertical positioning component 42 according to the diameter of the workpiece to ensure that the front and back and the height are in a straight line. Finally, fine-tune the axial positioning component through the transverse moving axial positioning support component 33, and the axial position of the workpiece 10 can be limited by its position. After the position is adjusted, the locking nut 52 locks it on the transverse moving axial positioning support component 33.

[0116] The speed regulating motor is installed on the longitudinal moving assembly, and the position of the longitudinal moving assembly is adjusted to make the pressing wheel 62 contact with the workpiece 10, and the pressing wheel 62 presses the workpiece 10 downward to prevent the workpiece 10 from radial movement. The speed regulating motor runs at a low speed to drive the pressing wheel 62 to rotate, and then drives the workpiece 10 to rotate.

[0117] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
