Description

Technical Field

[0001] This utility model relates to the field of three-axis positioning technology, specifically a three-axis linkage precision positioning structure in automated equipment. Background Technology

[0002] With the continuous advancement of industrial automation technology, the requirements for equipment precision and flexibility are also gradually increasing. In modern manufacturing, especially in fields such as aerospace, precision machinery, electronic assembly, and medical equipment, precise workpiece positioning is crucial. Traditional positioning devices mostly rely on two-dimensional planar positioning systems, which can typically only achieve coordinate adjustments within a single plane. This two-dimensional positioning technology has significant limitations, making it difficult to meet the precision machining needs that require adjustments at multiple angles and directions. Especially when handling complex shapes and large-sized workpieces, accuracy and efficiency are difficult to guarantee.

[0003] Existing two-dimensional planar positioning devices can only adjust position in the X and Y axes, and cannot perform precise positioning in the Z axis or more complex three-dimensional space. This leads to several problems: First, the workpiece is not accurately positioned in three-dimensional space, which can easily cause processing errors; second, it cannot achieve synchronous adjustment of multiple angles and axes, limiting the application of automated equipment in complex processes; finally, traditional positioning devices cannot provide sufficient flexibility and adaptability when dealing with different types of workpieces, resulting in low efficiency of the production line.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a three-axis linkage precision positioning structure for automated equipment. Utility Model Content

[0010] The lifting and rotating positioning module includes a lifting cylinder, a rotating cylinder, and a pneumatic clamp; the lifting cylinder is mounted on the left and right push blocks of the horizontal positioning module, the rotating cylinder is mounted on the piston rod end of the lifting cylinder, and the pneumatic clamp is mounted on the output shaft of the rotating cylinder, and the pneumatic clamp is provided with grippers for clamping the workpiece.

[0011] As a preferred technical solution, the flipping guide wheel is used to guide and limit the flipping trajectory of the flipping frame.

Detailed Implementation

[0022] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a three-axis linkage precision positioning structure technical solution for automated equipment: it consists of a column 1, a flip positioning module, a horizontal positioning module and a lifting and rotating positioning module.

[0024] For the flipping positioning module, the flipping cylinder 21 and the flipping guide frame 23 are mounted on the column 1, the flipping guide wheel 22 is set on the flipping guide frame 23, and the flipping frame 25 is rotatably mounted on the column 1 via the rotating shaft 24 and is driven by the flipping cylinder 21 to perform the flipping movement. In actual operation, the flipping cylinder 21 is activated, pushing the flipping frame 25 to flip around the rotating shaft 24. The flipping guide wheel 22 guides and restricts the flipping trajectory of the flipping frame 25 on the flipping guide frame 23, ensuring the stability and accuracy of the flipping action.

[0025] The horizontal positioning module is mounted on the flipping frame 25 of the flipping positioning module. Left and right cylinders 31 are mounted on the flipping frame 25, with their piston rods connected to the left and right push blocks 32. Left and right guide shafts 33 pass through guide sliders 34 and provide horizontal movement guidance for the left and right push blocks 32. When horizontal positioning is required, the left and right cylinders 31 are activated, pushing the left and right push blocks 32 to move horizontally along the left and right guide shafts 33. The guide sliders 34 ensure the smoothness and accuracy of the movement process, thereby achieving precise horizontal positioning of the workpiece.

[0026] The lifting and rotating positioning module is installed on the left and right push blocks 32 of the horizontal positioning module. The lifting cylinder 41 is mounted on the left and right push blocks 32, the rotating cylinder 42 is mounted on the piston rod end of the lifting cylinder 41, and the pneumatic clamp 43 is mounted on the output shaft of the rotating cylinder 42. The pneumatic clamp 43 is equipped with grippers 44 for holding the workpiece. In operation, the lifting cylinder 41 is activated, driving the rotating cylinder 42 and the pneumatic clamp 43 to move up and down. When a suitable height is reached, the rotating cylinder 42 is activated, driving the pneumatic clamp 43 to rotate 360 ​​degrees (because the rotating cylinder is a 360-degree rotating swing cylinder). The grippers 44 of the pneumatic clamp 43 hold the workpiece, achieving precise positioning of the workpiece in both the vertical and rotational directions. Among them, the cylinder body of the lifting cylinder 41 is provided with a buffer device between the cylinder body and the left and right push blocks 32 to reduce the impact force during the movement and protect the equipment; the pneumatic clamp 43 is a parallel opening and closing type or toggle type pneumatic finger, and its gripper 44 surface is provided with anti-slip texture or flexible pads to effectively prevent the workpiece from slipping and being damaged during the clamping process.

[0027] When using this three-axis linkage precision positioning structure, first install the equipment in a suitable position in the automated equipment and debug it to ensure that each module is operating normally.

[0028] Based on the initial position and shape of the workpiece, the flipping cylinder 21 of the flipping positioning module drives the flipping frame 25 to flip, adjusting the approximate angle and position of the workpiece.

[0029] The left and right cylinders 31 of the horizontal positioning module are activated, which push the left and right push blocks 32 to move the lifting and rotating positioning module and the workpiece horizontally, adjusting the workpiece to a suitable position in the horizontal direction.

[0030] The lifting cylinder 41 of the lifting and rotating positioning module is activated to lift the pneumatic clamp 43 and the workpiece to a suitable height. Then, the rotating cylinder 42 is activated to drive the pneumatic clamp 43 and the workpiece to rotate to the required angle. Finally, the workpiece is clamped by the jaws 44 of the pneumatic clamp 43, completing the precise positioning of the workpiece in three-dimensional space for subsequent processing operations.

[0031] Throughout the process, the modules work together to achieve precise positioning of the workpiece in three-dimensional space from multiple angles and directions, greatly improving processing accuracy and efficiency.
