[0028] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

The two groups of positioning members 5 are slidably provided on the moving member 3.

[0031] A driving assembly, which is disposed on the moving member 3 and is used to provide rotational power to the connecting member 4;

[0032] A power assembly is arranged inside the mounting base 1 and is used to provide lateral movement power to the moving member 3;

[0033] The conducting component is arranged on the driving component and is used to provide longitudinal moving power to the moving part 3; the connecting part 4 rotatably arranged in the inner hole of the moving part 3 and the two groups of positioning parts 5 symmetrically arranged on the connecting part 4 jointly construct a stable three-dimensional positioning system to ensure that the robot can be accurately and firmly positioned on the mounting part 6. The arrangement of multiple groups of limiting parts 2 and adjusting parts 24 further enhances the overall stability and positioning accuracy of the device and meets the needs of industrial robots in high-precision working occasions;

[0034] The driving component provides rotational power for the connecting part 4, so that the robot can rotate 360° on the horizontal plane to achieve all-round work coverage. The power component provides lateral movement power for the moving part 3, allowing the robot to quickly and smoothly move horizontally within a certain range. The transmission component provides longitudinal movement power for the moving part 3, so that the robot has the ability to move forward and backward. This multi-dimensional movement ability greatly improves the flexibility and working efficiency of the robot in a complex working environment.

[0035] The power assembly, the drive assembly and the transmission assembly are integrated into one, and the lateral, longitudinal and rotational movements of the moving part 3 are uniformly controlled, which simplifies the operation process, reduces the complexity of the system, and facilitates the user to quickly and accurately adjust the robot posture to adapt to different working tasks;

[0036] Each component including the mounting base 1, moving part 3, connecting part 4, positioning part 5, mounting part 6, limiting part 2, adjusting part 24, driving assembly, power assembly and conduction assembly adopts modular design, standard interface and connection method, and is easy to disassemble, replace or upgrade. When a component fails or needs to be upgraded, there is no need to replace the entire component, but only need to replace the corresponding module, which greatly reduces maintenance costs and downtime and improves the availability of equipment.

[0037] like Figures 1 to 5 As shown, as a preferred solution, the driving assembly includes a support member 7 arranged on the moving member 3, the support member 7 passes through the long slot hole of the mounting base 1, a conductive member 8 is rotatably arranged at the through hole of the support member 7, the conductive member 8 is coaxially installed with the connecting member 4, and the conductive member 8 is rotatably connected with the hole slot of the moving member 3, a worm gear 9 is coaxially arranged on the conductive member 8, an auxiliary member 10 is arranged on the support member 7, a worm 11 is rotatably arranged on the auxiliary member 10, and the worm 11 is meshed and connected with the worm gear 9;

[0038] The driving assembly includes a first motor 12 arranged inside the mounting base 1, a driving member 13 is coaxially arranged at the output end of the first motor 12, a multi-prism inner hole is arranged on the worm 11, and the driving member 13 is arranged in the multi-prism inner cavity of the worm 11; the driving assembly adopts the driving member 13 coaxially arranged at the output end of the first motor 12, and realizes efficient and direct power transmission by cooperating with the multi-prism inner hole of the worm 11, and the transmission relationship between the worm 11 and the driving member 13 remains unchanged when the connection position changes, and the meshing transmission of the worm 11 and the worm wheel 9 further transmits the power to the transmission member 8, and then the transmission member 8 is installed coaxially with the connecting member 4, and finally drives the connecting member 4 and the robot installed thereon to rotate. This precise transmission chain design reduces energy loss, improves overall transmission efficiency, helps save energy and reduce consumption, and ensures the smooth and accurate rotation of the robot;

[0039] The coaxial installation of the transmission member 8 and the connecting member 4, and the rotational connection between the transmission member 8 and the hole groove of the moving member 3, ensure the accuracy of the robot's rotation axis and avoid positioning deviations caused by transmission errors. The meshing transmission of the worm 11 and the worm wheel 9 has a self-locking characteristic, which can prevent the robot from accidentally rotating in a non-driven state and improve the positioning stability. In addition, the cooperation between the support member 7 and the long slot hole of the mounting base 1, and the support of the auxiliary member 10 to the worm 11, enhance the structural rigidity of the entire transmission system and further ensure the positioning accuracy.

[0040] The first motor 12 serves as a driving source, and centrally controls the rotation of the connecting member 4 through the connection between the driving member 13 and the worm 11. The user only needs to input instructions to the first motor 12 through the control system to realize the 360° rotation operation of the robot, which greatly simplifies the operation process and reduces the manual burden.

[0041] like Figures 1 to 5 As shown, as a preferred solution, the power assembly includes a lead screw 14 disposed inside the mounting base 1, at least one group of lead screws 14 is provided, and the lead screws 14 are disposed inside the threaded hole of the support member 7;

[0042] The power assembly also includes a second motor 15 arranged inside the mounting base 1, the second motor 15 is coaxially arranged on the lead-out member 16, the lead-out member 16 is coaxially arranged with a first gear 17, the lead screw 14 is coaxially arranged with a second gear 18, the second gear 18 is meshed and connected with the first gear 17, when multiple groups of lead screws 14 are provided, the second gears 18 on the multiple groups of lead screws 14 are all meshed and connected with the first gear 17; the lead screw 14 is used as a power transmission element, and its thread pair transmission has high transmission accuracy and self-locking performance, which can ensure that the moving part 3 is accurately positioned and does not slip during the lateral movement, and is particularly suitable for operating occasions that require high-precision positioning. The cooperation between the lead screw 14 and the threaded hole of the support member 7 further enhances the guiding property of the lateral movement of the moving part 3 and avoids positioning deviation caused by transmission clearance or deformation;

[0043] The second motor 15, as a power source, transmits power to the lead screw 14 smoothly and evenly through the transmission chain of the lead-out member 16, the first gear 17, and the second gear 18, thereby driving the moving member 3 to move laterally. This precise gear transmission system reduces vibration and impact, and ensures the stability of the moving process. When multiple sets of lead screws 14 are provided, the second gears 18 on all the lead screws 14 are meshed and connected with the first gear 17, achieving balanced distribution of power, avoiding tilting or jamming of the moving member 3 due to uneven load, and improving the stability of lateral movement;

[0044] Through the combination of the second motor 15, the lead-out piece 16, the first gear 17, the second gear 18 and the lead screw 14, the power is efficiently converted into linear motion, which reduces energy loss and improves power utilization. At the same time, the design of multiple sets of lead screws 14 can distribute the load according to actual needs, optimize power distribution, adapt to the lateral movement requirements under different load conditions, and further improve the power distribution efficiency.

[0046] The transmission component includes a third motor 21 arranged on the support member 7, a third gear 22 is coaxially arranged at the output end of the third motor 21, a fourth gear 23 is coaxially arranged on the transmission crankshaft 19, the third gear 22 is meshed and connected with the fourth gear 23, a damping pad is arranged at the connection between the transmission crankshaft 19 and the axial cavity of the transmission member 8, and the rotation resistance of the transmission crankshaft 19 and the transmission member 8 is greater than the external force driving power of the third motor 21 in the non-working state; the transmission crankshaft 19 is slidably arranged in the arc groove in the transmission member 20, forming a precise and stable transmission connection, ensuring that when the moving member 3 is moving longitudinally, the robot mounting member 6 can move and adjust at various angles in the same plane;

[0047] The third motor 21 serves as a power source, and transmits power to the transmission crankshaft 19 smoothly and evenly through the meshing transmission of the third gear 22 and the fourth gear 23, thereby driving the movable member 3 to move longitudinally. This precise gear transmission system reduces vibration and impact, and ensures the smoothness of the movement process. The damping pad provided at the connection between the transmission crankshaft 19 and the axial cavity of the conductive member 8 enables the transmission crankshaft 19 to rotate synchronously with the conductive member 8 when the mounting member 6 rotates. At this time, the third motor is in a forced rotation state, and the phase position of the mounting member 6 and the movable member 3 is stationary.

[0048] like Figures 1 to 5 As shown, as a preferred solution, its working process is as follows:

[0049] Robot rotation operation: The user sends a command to the first motor 12 through the control system, and the first motor 12 drives the driving member 13 to rotate, and transmits power to the worm 11 by cooperating with the multi-faceted inner hole of the worm 11. The worm 11 meshes with the worm wheel 9 to further transmit power to the transmission member 8. The transmission member 8 is coaxially installed with the connecting member 4, thereby driving the connecting member 4 and the robot installed thereon to rotate 360°;

[0050] The robot moves laterally: the user sends a command to the second motor 15 through the control system. The second motor 15 transmits power to the lead screw 14 smoothly and evenly through the transmission chain of the lead-out member 16, the first gear 17, and the second gear 18. The lead screw 14 acts as a power transmission element to drive the moving member 3 to move laterally.

[0051] Robot longitudinal movement and angle adjustment: The user sends instructions to the third motor 21 through the control system. The third motor 21 transmits power to the transmission crankshaft 19 through the meshing transmission of the third gear 22 and the fourth gear 23. The transmission crankshaft 19 is slidably set in the arc groove in the transmission member 20, driving the moving member 3 to move longitudinally.

[0052] The utility model provides a positioning slide for an industrial robot, and its installation method, connection method or setting method are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented.
