Detailed Description
In order to make the above objects, features and advantages of the present application more comprehensible, embodiments accompanied with figures are described in detail below.
Embodiments of the present application will now be described in detail with reference to the accompanying drawings. Reference will now be made in detail to the preferred embodiments of the present application, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. Furthermore, although terms used in the present application are selected from publicly known and commonly used terms, some terms mentioned in the present specification may be selected by the applicant at his or her discretion, the detailed meanings of which are described in relevant parts of the description herein. Furthermore, it is required that the present application is understood, not simply by the actual terms used but by the meaning of each term lying within.
Referring to fig. 1 and 2, the present application provides a scissor lifting mechanism, which includes a vertical platform 10, a scissor matching mechanism 20 and a driving mechanism 30, wherein a first sliding rail 110 and a second sliding rail 120 are arranged on the vertical platform 10 in parallel, and a sliding block 70 is arranged on the first sliding rail 110. The scissors assembly 20 is slidably engaged with the second rail 120 and has one end connected to the slider 70. The driving mechanism 30 is connected to the scissors assembly 20, and is used for driving the scissors assembly 20 to compress or relax, so as to drive the sliding block 70 to slide along the first sliding rail 110.
In one embodiment, a first slide rail 110 and a second slide rail 120 are provided on the vertical platform 10, the first slide rail 110 being used to limit the movement of the slider 70 such that the slider 70 moves along the first slide rail 110 under the drive of the drive mechanism 30. The second sliding rail 120 is used for limiting the movement of the scissor matching mechanism 20, so that the scissor matching mechanism 20 cannot deviate under the driving of the driving mechanism 30, and the scissor matching mechanism 20 cannot effectively support the sliding block 70 due to twisting.
Since the scissor assembly mechanism 20 is operated, it is necessary to ensure that the driving mechanisms 30 on both sides are operated synchronously, so that the resultant force of the driving forces generated by the two driving mechanisms 30 is consistent with the length extension direction of the first rail 110 and the second rail 120. In practical situations, the driving mechanism 30 is easy to be driven in a non-synchronous way, both sides of the scissor matching mechanism 20 are subjected to unbalanced force to generate distortion, so that a certain included angle is formed between the resultant force of the two driving mechanisms 30 applied to the scissor matching mechanism 20 and the length extension direction of the first sliding rail 110 and the second sliding rail 120, the resultant force of the driving mechanism 30 applied to the sliding block 70 is greatly weakened on the forming aspect of the included angle, moreover, the scissor matching mechanism 20 is subjected to unbalanced force to generate distortion force easily, and the force is easy to damage the scissor matching mechanism 20, so that the structural strength of the scissor matching mechanism 20 is greatly reduced.
Further, the forces output by the corresponding driving mechanisms 30 driven by different loads are also inconsistent, and if the resultant force of the scissors mating mechanism 20 is smaller than the resultant force which should be output originally, the motion precision of the motion platform 60 is positively affected.
Therefore, the present application can limit the operation of the scissor matching mechanism 20 under the driving of the first sliding rail 110 and the second sliding rail 120, even if the forces output by the driving mechanisms 30 at two sides of the scissor matching mechanism 20 are inconsistent, the forces are limited by the first sliding rail 110 and the second sliding rail 120, and the forces exerted by the driving mechanisms 30 on the scissor matching mechanism 20 are consistent with the length extension directions of the first sliding rail 110 and the second sliding rail 120 all the time, so that the driving stability of the sliding block 70, the connecting rod 50 and the moving platform 60 is further ensured.
In one embodiment, the scissor engagement mechanism 20 includes a bottom engagement mechanism 210, at least one middle engagement mechanism 220, and a top engagement mechanism 230, the middle engagement mechanism 220 being in rotational engagement with the bottom engagement mechanism 210 and the top engagement mechanism 230, respectively; opposite ends of the bottom mating mechanism 210 are respectively connected with one driving mechanism 30, and the middle part of the top mating mechanism 230 is connected with the slider 70.
Specifically, opposite ends of the side of the bottom mating mechanism 210 facing away from the middle mating mechanism 220 are each adapted to be connected to the drive mechanism 30.
The plurality of middle matching mechanisms 220 help to raise the height of the moving platform 60 so as to raise the moving platform 60 above the vertical platform 10, avoid interference of the vertical platform 10 to the movement of the moving platform 60, and meet the movement requirement of the moving platform 60 with a large angle.
The top mating mechanism 230 is used to connect with the slider 70, and the driving mechanism 30 may be, but not limited to, a driving motor, an oil cylinder, an air cylinder, or the like.
The bottom matching mechanism 210 drives the middle matching mechanism 220 and the top matching mechanism 230 to lift together under the driving of the driving mechanism 30, so that the force is transmitted to the sliding block 70, and the force is further transmitted to the connecting rod 50 and the moving platform 60 through the sliding block 70.
The present application is described by taking the driving mechanism 30 as a driving motor, and the driving mode of the driving motor is favorable for improving the motion precision and the dynamic response characteristic of the sliding block 70. Under the driving of the driving motor, the bottom matching mechanism 210 contracts, and then drives the middle matching mechanism 220 and the top matching mechanism 230 to perform contraction movement, so that the driving sliding block 70 slides along the first sliding rail 110.
In one embodiment, the bottom mating mechanism 210 includes two first scissor arms 211 that are engaged in a cross-over manner, wherein the middle portion of the two first scissor arms 211 is engaged in a rotation manner, two opposite sides of the two first scissor arms respectively extend out of two connecting ends 212, one of the connecting ends 212 is connected with the driving mechanism 30, and the other is connected with the middle portion mating mechanism 220 in a rotation manner.
The middle parts of the two first shearing arms 211 can be matched through rotation of the rotating shaft, and the two end parts of the two first shearing arms 211 are respectively connected with the driving mechanism 30 and the middle matching mechanism 220. The driving mechanism 30 drives the first scissor arm 211 to retract up and down, so as to drive the middle matching mechanism 220 and the top matching mechanism 230 to passively move up and down, and further drive the sliding block 70 to move up and down.
Further, each middle matching mechanism 220 includes two second shearing arms 221 which are matched in a crossed and rotating way, the middle parts of the two second shearing arms 221 are matched in a rotating way, and the end parts of the two second shearing arms 221 are matched with the first shearing arms 211 or the top matching mechanism 230 in a rotating way; the top matching mechanism 230 includes two third shearing arms 231, the two third shearing arms 231 are disposed at an included angle, one end of each third shearing arm is connected with the sliding block 70, and the other end of each third shearing arm is in running fit with the second shearing arm 221.
The number of the middle coupling mechanisms 220 may be plural, and the specific number may be determined according to the height of the vertical platform 10, so long as the moving platform 60 can move above the vertical platform 10 under the driving of the driving mechanism 30.
The contraction movement of the top engagement mechanism 230 and the middle engagement mechanism 220 is performed under the drive of the bottom engagement mechanism 210, and the bottom engagement mechanism 210, the middle engagement mechanism 220, and the top engagement mechanism 230 together constitute a support structure for the slider 70, the link 50, and the motion platform 60. Accordingly, the more stable the operation of the top engagement mechanism 230, the middle engagement mechanism 220, and the bottom engagement mechanism 210, the more support force is to the slider 70, the link 50, and the motion platform 60.
In one embodiment, the bottom mating mechanism 210, the middle mating mechanism 220, and the top mating mechanism 230 are slidably mated with the second rail 120, respectively, at their opposite ends.
In order to meet the miniaturization design of the whole device, a space for avoiding the shearing mechanism is formed in the inner side of the vertical platform 10, the shearing mechanism is partially accommodated in the space, the second sliding rail 120 is also formed in the space, and the shearing mechanism is in sliding fit with the second sliding rail 120 towards the end part of the space, so that the operation state of the shearing mechanism is limited.
That is, when the two driving mechanisms 30 are not synchronously driven, the movement of the scissor mechanism is limited by the second sliding rail 120, and the force applied to the slider 70 is also directed to the length extending direction of the second sliding rail 120, so that the scissor mechanism is prevented from being distorted and damaged in the driving process, and the operation stability of the scissor mechanism is ensured.
In still another embodiment, a third slide rail (not shown) may be further provided, and the third slide rail and the second slide rail 120 respectively define opposite sides of the scissor assembly mechanism 20, so that the definition of the scissor assembly mechanism 20 may be further improved.
In one embodiment, the scissor lift mechanism further comprises a base 40, and the driving mechanism 30 is disposed on the base 40; a connecting seat 410 is further arranged between the bottom matching mechanism 210 and the driving mechanism 30, and the connecting seat 410 is in sliding fit with the base 40.
The driving direction of the driving mechanism 30 is transverse, the moving direction of the sliding block 70 is vertical, the transverse driving force of the driving mechanism 30 can be converted into the sliding of the sliding block 70 along the vertical direction under the adjustment of the shearing mechanism, and then the driving mechanism 30 does not participate in the movement, and the shearing mechanism, the connecting rod 50, the sliding block 70 and other structures participating in the movement are small in self mass and volume, so that the dynamic response characteristic of the movement platform 60 is improved.
Moreover, the drive mechanism 30 is configured for lateral drive to facilitate heavy load support requirements. Because once the drive mechanism 30 is set to the vertical, the drive mechanism 30 itself becomes the main support of the load, and the drive mechanism 30 itself does not have such support strength. Therefore, the force of the output of the driving mechanism 30 needs to be set to be transverse, and then the scissor-fitting mechanism 20 is used as a main supporting structure of the load, so that the heavy-load supporting requirement can be satisfied.
The connecting seat 410 and the base 40 may be slidably engaged by a sliding structure such as a sliding shaft or a sliding groove, which is not limited herein.
In one embodiment, the middle portions of the bottom mating mechanism 210, the middle mating mechanism 220, and the top mating mechanism 230 are coaxial and disposed parallel to the first rail 110 and the second rail 120.
The middle parts of the bottom matching mechanism 210, the middle matching mechanism 220 and the top matching mechanism 230 are adjusted to be parallel to the first sliding rail 110 and the second sliding rail 120, which is beneficial to outputting more stable driving force to the sliding block 70 by the scissor mechanism and is also beneficial to prolonging the service life of the scissor mechanism.
Further, the structural dimensions of the top mating mechanism 230, the middle mating mechanism 220, and the bottom mating mechanism 210 are increased.
The structural dimensions of the top matching mechanism 230, the middle matching mechanism 220 and the bottom matching mechanism 210 are set to be in an increasing mode, so that the shape of the whole scissor matching mechanism 20 is close to a triangle, and the triangle has the most stable supporting force, thereby being beneficial to improving the stability of the structure of the scissor mechanism and meeting the heavy-load supporting requirement.
In one embodiment, the top engagement mechanism 230, the middle engagement mechanism 220, and the bottom engagement mechanism 210 are each further provided with a plurality of weight-reducing apertures 240.
The lightening holes 240 may be round holes, square holes, shaped holes, etc., and are not limited herein. The lightening holes 240 may further lighten the movable structure and further improve the dynamic response characteristics of the driving motor to the moving platform 60.
The application also provides a six-degree-of-freedom swinging device, which comprises a connecting rod 50, a moving platform 60 and the scissor lifting mechanism, wherein one end of the connecting rod 50 is in two-degree-of-freedom rotation fit with a sliding block 70, and the other end of the connecting rod 50 is in three-degree-of-freedom rotation fit with the moving platform 60, so that the moving platform 60 can meet the driving of six degrees of freedom under the driving of the driving mechanism 30.
