Description

Technical Field

[0001] This utility model relates to the field of guide rail device technology, and more specifically, to a manual displacement platform. Background Technology

[0002] A manual displacement platform is a mechanical device used to manually move objects in space. It can be used in various fields such as industrial production, medical devices, and scientific research. A manual displacement platform typically consists of a worktable, guide rails, handles, scales, and fixing devices, providing stable and precise displacement adjustment. Existing displacement platforms on the market often have low load capacities and cannot be adjusted using matching tools. Under heavy loads, adjustment becomes difficult, knobs become loose, and some rotating modules malfunction during use. Traditional multi-degree-of-freedom displacement adjustment platforms can no longer meet the needs of complex and high-load actual working conditions.

These four modules are connected sequentially from bottom to top. The base of the Z-axis linear displacement module is generally fixed, and a sleeve drives the other three modules to complete Z-axis linear motion. The XY-axis linear displacement module can drive the two modules above it to complete X and Y-axis linear motion. The XY-axis rotary displacement module drives the Z-axis rotary displacement module to complete X and Y-axis axial rotation. The Z-axis rotary displacement module enables the cover plate to rotate axially in the Z-direction. The cover plate is generally connected to the target carrier. Through bottom-up motion transmission, the target's displacement can be adjusted in six degrees of freedom in space. Each degree of freedom is equipped with a locking device to lock the position in each degree of freedom. This stable and reliable locking function makes the platform of this embodiment sufficient to meet displacement requirements under heavy load conditions, solving the problem that existing mobile platforms cannot meet application requirements under heavy loads. Furthermore, it can be easily adjusted using tools, has a simple structure, is labor-saving to use, and has high adjustment efficiency.

[0016] The innovative aspects of the embodiments in this specification include: 1. In this specification, the entire platform has a compact structure and transmits motion from bottom to top. It first performs linear displacement in the ZXY direction, and then performs rotational displacement around the XY axis to complete a 360° rotation around the Z axis. This realizes the flexible adjustment of the manually moved platform in six degrees of freedom, which is one of the innovative points of the embodiments in this specification.

[0017] 2.

Detailed Implementation

[0021] The technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] It should be noted that the terms "comprising" and "having," and any variations thereof, in the embodiments and drawings of this specification are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0023] This specification discloses a manual displacement platform, which will be described in detail below.

[0024] Figure 1 This is a schematic diagram of a manually operated displacement platform provided in one embodiment of this specification. The platform is a multi-layered stacked structure, such as... Figure 1As shown, the manual displacement platform can include four functional modules arranged coaxially from bottom to top and fixedly connected by screws: Z-axis linear displacement module 1, XY-axis linear displacement module 2, XY-axis rotary displacement module 3, and Z-axis rotary displacement module 4. The connection relationship between the modules forms a motion transmission chain. Z-axis linear displacement module 1 is located at the bottom layer, and its top is fixedly connected to the bottom of the XY-axis linear displacement module 2 above it. The top of XY-axis linear displacement module 2 is fixedly connected to the bottom of the XY-axis rotary displacement module 3. The top of the XY-axis rotary displacement module 3 is fixedly connected to the bottom of the Z-axis rotary displacement module 4. The top of the Z-axis rotary displacement module 4 is provided with a cover plate 44 for mounting a target carrier. This cover plate 44 can serve as a mounting surface for target carriers such as optical devices and sensors; that is, the cover plate 44 serves as the final output end and load mounting interface of the entire motion chain.

[0025] The motion transmission path of the above technical solution is explained below. When the Z-axis linear displacement module 1 moves, it will drive all the modules above it to move linearly in the Z-axis as a whole. The XY-axis linear displacement module 2 can realize linear movement in the X and Y directions, and drive the XY-axis rotational displacement module 3 and the Z-axis rotational displacement module 4 above it to move together in the XY plane. The top of the XY-axis rotational displacement module 3 is fixedly connected to the bottom of the Z-axis rotational displacement module 4. This module can realize rotational swing around the X and Y axes, and drive the Z-axis rotational displacement module 4 above it to perform pitch (rotation around the X axis) and roll (rotation around the Y axis) movements. The Z-axis rotational displacement module 4 can make the cover plate 44 and the target carrier on it rotate 360° around the Z axis. Through this layer-by-layer motion transmission mechanism from bottom to top, the target carrier installed on the cover plate 44 can obtain three linear degrees of freedom (X, Y, Z) and three rotational degrees of freedom (rotation around the X axis, rotation around the Y axis, and rotation around the Z axis) in space, for a total of six degrees of freedom of displacement adjustment capability.

[0026] The driving and control methods of the above technical solution are described below. Each module in this application is equipped with an adjustment knob and a locking knob. Thus, the operator can manually rotate the corresponding adjustment knob of each module to convert the rotational motion into linear displacement or rotation in the required direction of that module via a transmission mechanism such as a slider or linkage. Simultaneously, after the target carrier is adjusted to the required posture, tightening the locking knob of each module can lock the motion of that degree of freedom, preventing it from shifting under load or external force, and ensuring the stability and reliability of the posture.

[0027] In summary, the platform's design enables motion decoupling and hierarchical transmission. The motion of the bottom module (Z-axis linear motion) affects the reference position of the entire platform, while the motion of the top module (Z-axis rotation) only changes the orientation of the end-effector. This structure allows for both global (through the lower module) and local precision (through the upper module) adjustment of the end-effector's pose.
