[0038] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. It should also be understood that after reading the contents of the present invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined by the appended claims.

[0039] See also Figures 1 to 6 , specific embodiment 1, this embodiment 1 provides a three-axis positioning device, including a Z-direction drive mechanism for moving the positioning pin 1 in the vertical direction, a Y-direction drive mechanism for moving the Z-direction drive mechanism in the front-to-back direction, and an X-direction drive mechanism for moving the Y-direction drive mechanism in the left-to-right direction, the flat plate 9 of the Z-direction drive mechanism is connected to the second slider 111 of the Y-direction drive mechanism, the third connecting plate 15 of the Y-direction drive mechanism is connected to the third slider 241 of the X-direction drive mechanism, and the X-direction drive mechanism is fixed on the base plate 34.

[0040] The Z-drive mechanism also includes a first connecting plate 2, a first bracket 3, a second connecting plate 4, a Z-direction linear module 5, a first motor 6 (a Yaskawa motor can be used), and a second bracket 8. The second bracket 8 is in the shape of a vertical strip. The bottom of the second bracket 8 is connected to the flat plate 9, and the side of the second bracket 8 is connected to the Z-direction linear module 5. The first slider 51 of the Z-direction linear module 5 is driven by the first motor 6 to achieve vertical movement. The first slider 51 is connected to the second connecting plate 4, and the second connecting plate 4 is connected to the first bracket 3. The top of the first bracket 3 is connected to the horizontal first connecting plate 2, and the first connecting plate 2 is connected to the vertical positioning pin 1. Under the control of the first motor 6, the Z-direction linear module 5 drives the positioning pin 1 (i.e., used to position the product or workpiece and match the workpiece hole) to move in the Z direction. The positioning pin 1 is detachably connected to the first connecting plate 2 to facilitate the replacement of the positioning pin 1 size.

[0041] A linear module, also known as a linear actuator, is a linear motion platform module that precisely assembles a guide system and a transmission system into a single unit. Typically consisting of a motor, reducer, guide rails, and a support frame system, it enables high-speed, high-precision, and high-load linear motion. As linear modules are currently available, they will not be discussed in detail here.

[0042] A first stopper 7 is provided at the bottom of the second bracket 8, facing the Z-axis linear module 5. The first slider 51 is provided with a first positioning hole A52. The first stopper 7 also has a first positioning hole B71. The first positioning hole A52 and the first positioning hole B71 correspond to each other. Specifically, when the first slider 51 slides to the bottom of the Z-axis linear module 5, the first positioning hole A52 and the first positioning hole B71 overlap. A first positioning pin 1 (not shown in the drawings) is used to position the first slider 51, preventing it from moving. The first positioning hole B71 has two holes at different heights, which can be used to control the first slider 51 at different heights.

[0043] The Y-direction drive mechanism also includes a Y-direction linear module 11, a second motor 10 (Yaskawa motor can be selected) and a second limit block 12. The Y-direction linear module 11 is arranged on the third connecting plate 15. The second slider 111 of the Y-direction linear module 11 is driven by the second motor 10 to realize Y-direction linear movement; the Y-direction linear module 11 drives the Z-direction drive mechanism to move in the Y-direction under the control of the second motor 10, indirectly realizing the Y-direction movement of the positioning pin 1.

[0044] The second stopper 12 is mounted on the third connecting plate 15 on one side of the Y-axis linear module 11. The second slider 111 is provided with a second positioning hole C112. The second stopper 12 is also provided with a second positioning hole D121. The second positioning hole C112 corresponds to the second positioning hole D121. Specifically, when the second slider 111 slides to one end of the Y-axis linear module 11, such as the end of the Y-axis linear module 11 near the second motor 10, the second positioning hole C112 and the second positioning hole D121 coincide. The second positioning pin 1 (not shown in the drawings) is used to position the second slider 111, preventing it from moving. The second positioning hole D121 has two holes at different locations, which can be used to control the second slider 111 in different positions.

[0045] The second slider 111 of the Y-direction linear module 11 is connected to the flat plate 9 , and the flat plate 9 is used to support the Z-direction driving mechanism so that the positioning pin can move in the Y direction through the Y-direction linear module 11 .

[0046] The third connecting plate 15 is also provided with a Y-guide rail 16, which is parallel to the Y-linear module 11. The Y-guide rail 16 is connected to a Y-slider 161, which is connected to the flat plate 9 through a second L-shaped connecting plate 17. The third connecting plates 15 corresponding to the two ends of the Y-guide rail 16 are respectively provided with a first baffle 13 and a fourth baffle 14, which limit the moving range of the Y-slider 161, and the Y-slider 161 is connected to the flat plate 9 through the second L-shaped connecting plate 17, and the flat plate 9 is connected to the second slider 111. Therefore, the Y-guide rail 16 and the Y-slider 161 are used to indirectly limit the moving range of the second slider 111 of the Y-linear module 11. At the same time, the Y-slider 161 can share the weight of the flat plate 9 and help the flat plate 9 maintain balance, that is, the Y-guide rail 16 assists in supporting the balancing movement of the Y-linear module 11 when it moves back and forth.

[0047] A second Z-shaped partition plate 18 is installed between the Y-direction guide rail 16 and the Y-direction linear module 11. The taller horizontal plate of the second Z-shaped partition plate 18 is located between the Y-direction slider 161 and the flat plate 9. The third connecting plate 15 is also connected to a second U-shaped bent plate 21. A second tank chain 20 is mounted on this second U-shaped bent plate 21. The taller end of the second tank chain 20 is connected to the flat plate 9 via a second Z-shaped bracket 19. The second tank chain 20 protects the Y-direction moving circuitry, facilitating future maintenance and replacement of new circuitry.

[0048] The X-direction drive mechanism also includes an X-direction linear module 24, a third motor 23 (a Yaskawa motor can be selected), and a third limit block 25. The X-direction linear module 24 is arranged on the base plate 34. The third slider 241 of the X-direction linear module 24 is driven by the third motor 23 to achieve X-direction linear movement; under the control of the third motor 23, the X-direction linear module 24 drives the Z-direction drive mechanism and the Y-direction drive mechanism to move in the X direction, indirectly achieving the X-direction movement of the positioning pin 1. At this time, the positioning pin 1 can achieve free movement in the three directions of X / Y / Z.

[0049] The third stopper 25 is mounted on the base plate 34 on one side of the X-axis linear module 24. The third slider 241 is provided with a third positioning hole E242, and the third stopper 25 is provided with a third positioning hole F251. The third positioning hole E242 and the third positioning hole F251 correspond to each other. Specifically, when the third slider 241 slides to one end of the X-axis linear module 24, such as the end of the X-axis linear module 24 near the third motor 23, the third positioning hole E242 and the third positioning hole F251 coincide with each other. A third positioning pin 1 (not shown) is used to position the third slider 241, preventing it from moving. The third positioning hole F251 has two holes at different locations, which can be used to control the third slider 241 in different positions.

[0050] The third slider 241 of the X-axis linear module 24 is connected to the square plate, and the square plate is connected to the third connecting plate 15, so as to facilitate separation of the Y-axis driving mechanism and the X-axis driving mechanism and facilitate disassembly and replacement of their respective components.

[0051] The base plate 34 is also provided with an X-direction guide rail 26, which is parallel to the X-direction linear module 24. The X-direction guide rail 26 connects to an X-direction slider 261, which is connected to the square plate via a third L-shaped connecting plate 30, which is in turn connected to the third connecting plate 15. A second stopper 27 and a third stopper 28 are respectively provided on the base plate 34 at either end of the X-direction guide rail 26. The second stopper 27 and the third stopper 28 limit the range of motion of the X-direction slider 261. The X-direction slider 261 is connected to the square plate via the third L-shaped connecting plate 30, which is in turn connected to the third slider 241. Therefore, the X-direction guide rail 26 and the X-direction slider 261 indirectly limit the range of motion of the third slider 241 of the X-direction linear module 24. Furthermore, the X-direction slider 261 shares the weight of the flat plate 9, helping to maintain balance between the square plate and the third connecting plate 15. Specifically, the X-direction guide rail 26 provides auxiliary support and balancing for the X-direction linear module 24 during left and right movement.

[0052] A third Z-shaped partition plate 29 is provided between the X-direction guide rail 26 and the X-direction linear module 24 . The higher transverse plate of the third Z-shaped partition plate 29 is located between the X-direction slider 261 and the third connecting plate 15 .

[0053] A third U-shaped bent plate 31 is also provided on the bottom plate 34. A third tank chain 33 is provided within the third U-shaped bent plate 31. The higher end of the third tank chain 33 is connected to the third connecting plate 15 via a third Z-shaped bracket 32. The third tank chain 33 protects the circuit in the X-direction motion state, facilitating future maintenance and replacement of new circuits.

[0054] A reinforcing plate 81 is further provided between the flat plate 9 and the second bracket 8 .

[0055] The working principle and usage process of the utility model are as follows: the three-axis positioning device drives the Z-direction linear module 5 through the first motor 6 to make the first driving positioning pin 1 of the Z-direction linear module 5 move up and down, the second motor 10 drives the Y-direction linear module 11 so that the second slider 111 of the Y-direction linear module 11 can drive the flat plate 9 fixing the Z-direction linear module 5 to move in the Y direction (so that the Z-direction linear module 5 can move forward and backward), the third motor 23 drives the X-direction linear module 24 so that the third slider 241 of the X-direction linear module 24 can drive the third connecting plate 15 fixing the Y-direction linear module 11 to move in the X direction, so that the Y-direction linear module 11 and the Z-direction linear module 5 connected thereto can drive the positioning pin 1 to move left and right. When the work stops, the X / Y / Z-direction linear module 5 returns to the origin, and the hole on the slider of the X / Y / Z-direction linear module 5 coincides with the hole on the limit block. At this time, a pin can be inserted to fix the X / Y / Z-direction linear module 5 to prevent movement.
