Description

Technical Field

[0001] The present invention relates to the field of motion platforms, and more specifically, to a multi-axis motion platform. Background Art

[0002] In the existing mechanical manufacturing technology practice, XY linear motion platform is widely used. Many manufacturing companies need XY linear motion platform to realize various manufacturing processes such as dispensing, welding, assembly, etc. It is also suitable for the operation of mechanical processing equipment and various cutting equipment. It has a very important application role and is a universal working platform.

[0003] However, in some non-standard mechanical design processes, especially for some processing equipment with multi-angle adjustment and rotation requirements, additional superimposed rotating structures are required. The current mainstream relies on hollow rotating platforms as the main actuators. Although they can be used separately as modules and are easy to disassemble and assemble, there are other problems: the hollow rotating platform can only rotate in a certain dimension. For adjustment of other angles, only a rotating structure in another direction can be superimposed, which makes the overall structural layout inconvenient. Moreover, the locking strength of this type of rotating structure depends entirely on the self-locking force of the motor itself, which is not effective. The load is concentrated on the motor, which can easily cause damage to the motor. Especially for some superimposed rotating structures, there is a lack of interrelated locking components, and the probability of damage is higher, which needs to be improved.

[0033] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0034] like Figures 1 to 4 As shown, a multi-axis motion platform is disclosed in a specific embodiment of the present invention, comprising a first platform 100, a second platform 200, and a third platform 300 which are stacked in sequence along the vertical direction; the first platform at least provides horizontal movement and / or vertical movement; the second platform provides horizontal rotation movement; a support frame 400 is installed on the third platform 300, and the third platform drives the support frame to rotate and swing in the vertical direction; a locking structure 500 is installed on the third platform 300, which is used to lock the support frame 400 after it is rotated into place;

[0035] The above-mentioned multi-axis motion platform can move in multiple directions when combined with each other, meet different processing requirements, and expand the scope of application; wherein, a locking structure is installed on the third platform, which is used to lock the support frame after it is rotated into place, providing a locking force in addition to the self-locking of the motor, providing a more stable locking effect, reducing the load stress on the motor, preventing motor damage, and extending the service life.

[0036] It should be noted that the second platform is installed on the topmost moving part of the first platform, the third platform is installed on the rotating part of the second platform, and the support frame is installed on the rotating part of the third platform. Under the coordinated movement of multiple platforms, the support frame is driven to move in multiple dimensions; among them, the first platform includes but is not limited to a single-axis horizontal / vertical moving platform, or a dual-axis horizontal / horizontal-vertical moving platform, or a three-way moving platform, providing the required lateral and / or vertical movement; the above-mentioned motion platforms are relatively common and will not be elaborated in detail.

[0037] Furthermore, the second platform 200 is a hollow rotating platform; the third platform 300 includes a casing 310 with an open bottom, and the bottom of the casing 310 is installed on the rotating part of the second platform 200 by bolts; the locking structure 500 is arranged inside the casing and the second platform, and the rotation movement of the second platform 200 and the third platform 300 is simultaneously limited, so as to realize the linkage locking cooperation between the two rotating structures, on the one hand, strengthening the overall locking force and providing more stable support; on the other hand, it can further disperse the load force of the motor and transfer the force to other structural components to prevent damage to the motor; it should be noted that the hollow rotating platform is also a common motion platform, and the specific structure will not be repeated.

[0038] Furthermore, the locking structure 500 includes a first locking mechanism 510 and a second locking mechanism 520; the first locking mechanism and the second locking mechanism are adjusted to move synchronously, and the rotational movements of the second platform 200 and the third platform 300 are limited respectively; separate locking mechanisms are adopted, but the two mechanisms have linkage and coordination movements, and can be driven by the same power component to reduce the use of electrical components, and can also achieve synchronous locking movements of the two, and utilize the limited coordination of the two locking mechanisms themselves to further enhance the transmission and dispersion of force and better reduce the load.

[0039] Furthermore, if Figure 2 As shown, a gear ring 210 is fixedly provided on the inner ring wall of the second platform 200. This part does not rotate and provides a fixed point for locking; Figure 4 , Figure 5As shown, the first locking mechanism 510 includes a support shaft 511, an electric push rod 512, and a first universal sleeve 513; the support shaft 511 includes a first rod body 5111, a second rod body 5112, and a third rod body 5113 connected in sequence from bottom to top, the diameter of the second rod body 5112 is larger than the diameter of the first rod body 5111, and a step portion is formed at the connection; the first rod body 5111 is installed on the inner wall of the housing 310 through a linear bearing, and the piston rod end of the electric push rod 512 is A first push frame 514 is installed, and a first guide hole is provided on the first push frame. The aperture of the first guide hole is adapted to the diameter of the first rod body. The first rod body is movably arranged between the first push frame and the linear bearing; the top surface of the first push frame 514 abuts against the bottom surface of the second rod body 512; the electric push rod is used to drive the support shaft to move upward; a third gear 515 is fixedly provided at the bottom end of the first rod body 5111, and the third gear 515 is meshed with the gear ring 210 for transmission; the third rod body 5113 is a prismatic structure, The first universal sleeve 513 is located above the support shaft 511 and is fixedly mounted on the bracket 320 inside the casing; the third rod body pushed upward is stuck in the first universal sleeve to lock the support shaft, and the casing cannot rotate along the gear ring through the third gear, thereby locking the casing and limiting the rotation movement of the second platform; in the above-mentioned structural design, the gear ring is fixed on the inner ring wall of the second platform, and it is in a fixed position relative to the rotating part of the second platform, and the third platform is installed on the rotating part of the second platform, which means that the gear ring is also in a fixed position relative to the third platform; when not locked, the support shaft rotates, and the third gear is engaged with the gear ring, which does not affect the rotation of the third platform; when the electric push rod drives the support shaft to move up to the third rod body and is stuck in the first universal sleeve, the support shaft cannot rotate, which means that the third gear cannot rotate along the gear ring, and the third platform cannot rotate, thereby achieving the desired locking effect.

[0040] Furthermore, if Figure 2 As shown, the bottom of the two opposite side walls of the support frame 400 are respectively installed with a first rotating shaft 410 and a second rotating shaft 420; the top of the two opposite side walls of the housing is provided with a first through hole, and the first through hole is installed with a first bearing seat, and the first rotating shaft and the second rotating shaft are respectively rotatably installed at the first bearing seat and the second bearing seat, so that the support frame 400 is rotatably installed on the top of the housing 310; Figure 4As shown, a first motor 330 is fixedly mounted on the bracket 320, a first gear 340 is fixedly mounted on the output shaft of the first motor 330, a second gear 430 is fixedly mounted on the first rotating shaft 410, the second gear 430 is meshed with the first gear 340 for transmission, and the first motor 330 is used to drive the support frame 400 to rotate and swing; the second locking mechanism 520 moves synchronously with the first locking mechanism 510, and is used to lock the first rotating shaft 410, thereby locking the entire support frame 400; with the above structure, the support frame is driven to rotate and swing by the first motor, the overall structure is simple, and also provides installation conditions for the subsequent structure for locking the support frame;

[0041] Furthermore, if Figure 6 As shown, a clamping block 440 is fixedly provided at the end of the first rotating shaft 410, and the clamping block is a prismatic structure; Figure 4 , Figure 7 As shown, the second locking mechanism 520 includes a second push frame 521, a spring 522, and a second universal sleeve 523; two guide rods 524 are fixedly provided on one side of the second push frame 521 close to the first rotating shaft, and a second guide hole is provided on the bracket corresponding to the guide rod. The guide rod movably passes through the second guide hole, and the end is limited by a retaining spring; the spring 522 is sleeved on the guide rod 524 to provide the second push frame with a thrust in the direction of the second rotating shaft; the second universal sleeve 523 is fixedly installed on the second push frame 521, and its position corresponds to the clamping block 440; when the second push frame is only acted upon by the elastic force of the spring, the second universal sleeve is separated from the clamping block, and the first rotating shaft is in a rotating state; when the electric push rod is started, the support shaft pushed upward provides the second push frame with a thrust of the compression spring, so that the second universal sleeve is sleeved on the clamping block to lock the first rotating shaft, thereby locking the support frame;

[0042] Among them, the second push frame is installed on the bracket through two guide rods, and the second push frame can only move along the direction of the guide rods and cannot rotate; the second universal sleeve is installed on the second push frame, which means that the second universal sleeve can also only move along the direction of the guide rods and cannot rotate; therefore, the block at the end of the first rotating shaft is locked by the second universal sleeve, so that the first rotating shaft cannot rotate, thereby completing the locking of the support frame;

[0043] More specifically, when the electric push rod is working, it drives the support shaft to move upward, and during the movement, the second push frame moves toward the first rotating shaft; when the support shaft rises to a preset height position, the third column is clamped at the first universal sleeve, and the second universal sleeve is sleeved on the outside of the clamping block, thereby synchronously locking the rotating parts of the second platform and the third platform, maintaining them in a stable position and not easily loosening, and effectively dispersing the force to prevent damage caused by excessive concentration of local force;

[0044] It should be noted that the first universal socket and the second universal socket are universal wrench structures, which can be purchased and used on the market, and the specific structures are not described in detail.

[0045] Furthermore, if Figure 8 , Fig. 9 As shown, the second push frame 521 includes a push plate 525, and two guide rods 524 are respectively arranged at the two ends of the side wall of the push plate 525 close to the first rotating shaft; a push block 526 is fixedly arranged in the middle of the other side wall of the push plate 525, and the side of the push block away from the push plate is an inclined structure, and the lower end of the inclined surface is inclined to the side of the push plate; a notch 527 larger than the maximum diameter of the third rod body 5113 is arranged in the middle of the push block 526; Figure 5 As shown, the top of the second rod body 5112 is narrowed and has a frustum-shaped structure. The conical surface formed is slidably connected with the inclined surface of the push block, and the second rod body 5112 pushed upward provides a lateral thrust to the second push frame 521; by adopting the inclined surface sliding connection method, part of the force of the support shaft moving upward is converted into a lateral force to push the second push frame, thereby achieving the desired synchronous movement effect; when the force is released, the support shaft will fall back downward under its own gravity, and the second push frame will also move in the direction under the action of the spring, which will also prevent the support shaft from falling and quickly reset to the unlocked state to maintain the desired rotation and swinging action.

[0046] Furthermore, if Fig.10 As shown, a first bayonet 321 is provided on the top surface of the bracket 320 corresponding to the third rod body, and a second bayonet 322 is provided on the side wall of the bracket 320 corresponding to the block, and both the first bayonet and the second bayonet are prismatic hole structures; the outer walls of the first universal sleeve and the second universal sleeve are prismatic structures; the first universal sleeve 530 is adapted to be clamped in the first bayonet 321, and the top of the first universal sleeve is fixed to the bracket by bolts; the second universal sleeve 523 is adapted to be penetrated at the second bayonet 322 and slides along the second bayonet; the above structure can further strengthen the connection strength between the first universal sleeve and the bracket, and further limit the moving trajectory of the second universal sleeve, and can transfer the force of the second universal sleeve to the bracket, further disperse it, and prevent the connection between the second universal sleeve and the second push frame from being damaged due to concentrated force.

[0047] The present invention is described by preferred embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention.
