Description

Technical Field

[0002] A displacement platform is a device used to precisely control the movement of an object in a specific direction, and it can achieve high-precision position adjustment. This device is widely used in many fields such as scientific research, industrial automation, precision machining, optical experiments, and biotechnology. According to the motion mode and control requirements, displacement platforms can be divided into different types, including single-axis displacement platforms, multi-axis displacement platforms, manual displacement platforms, and electric displacement platforms, etc.

[0003] After retrieval, the existing Chinese patent publication number is: CN219234402U, which provides a displacement platform, including: an X-axis displacement component, the X-axis displacement component includes a first "U"-shaped bracket and a first lead screw drive mechanism arranged on the first "U"-shaped bracket; a Y-axis displacement component, the Y-axis displacement component includes a second "U"-shaped bracket arranged crosswise with the first "U"-shaped bracket and a second lead screw drive mechanism arranged on the second "U"-shaped bracket, and the first "U"-shaped bracket is connected to the output screw block of the first lead screw drive mechanism; a rotation drive mechanism, the rotation drive mechanism is fixed on the output screw block of the second lead screw drive mechanism; a workpiece fixing plate, the workpiece fixing plate is connected to the output end of the rotation drive mechanism. This patent can complete the position adjustment in the X-axis direction, the position adjustment in the Y-axis direction, and the angle adjustment at a specific position by setting the X-axis displacement component, the Y-axis displacement component, and the rotation drive mechanism, so as to perform two-axis and rotation adjustments on the processed workpiece according to the working conditions.

[0004] Although the above patent can complete the position adjustment in the X-axis direction, the position adjustment in the Y-axis direction, and the angle adjustment at a specific position, so as to perform two-axis and rotation adjustments on the processed workpiece according to the working conditions, the above displacement platform still has the following problems: when the displacement platform cannot perform vertical angle adjustment, its flexibility in use is relatively reduced. In occasions where it is necessary to adjust an object or equipment to a specific angle to meet the experimental, measurement, or processing requirements, this type of displacement platform may not be able to meet the needs; in the case of no vertical angle adjustment function, users may need to use other external devices or complex settings to compensate for this defect, which not only increases the complexity of the operation, but also may affect the overall working efficiency, the accuracy of the final result, and the cost of the entire equipment.

[0005] In view of the above problems, for this reason, a displacement platform with adjustable verticality and angle is proposed. Content of the Utility Model

[0006] The utility model aims to provide a displacement platform with adjustable verticality and angle, which solves the problem that when the displacement platform in the background technology cannot adjust the vertical angle, its flexibility of use is relatively reduced, and when an object or equipment needs to be adjusted to a specific angle to adapt to experimental, measurement or processing requirements, this type of displacement platform may not be able to meet the requirements.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a displacement platform with adjustable verticality and angle, comprising a bottom frame, a platform body is arranged on the top of the bottom frame, a rotating block is fixed at the bottom center of the platform body, a double linkage rod is rotated inside the rotating block, a hollow prism is fixed at the bottom of the bottom frame, a fixing plate is fixed at the bottom of the inner wall of the hollow prism, a servo motor is fixed at the front end of the fixing plate, a driving rod is passed through and fixed at the output end of the servo motor, a single linkage rod is fixed above the driving rod, and one end of the single linkage rod is rotatably connected to the double linkage rod; an all-round angle adjustment mechanism is arranged at the bottom of the hollow prism.

[0008] By adopting the above technical solution, the servo motor is used as a driving source, and in conjunction with the single linkage rod and the double linkage rod, the vertical angle of the platform body is changed.

[0009] As a further description of the above technical solution: a connecting block is fixed at the top left position of the bottom frame, connecting ears are fixed at the front and rear ends of the left side of the platform body, and the connecting ears are hingedly connected to the connecting block.

[0010] By adopting the above technical solution, the platform body is allowed to rotate around the connecting block within a certain range, thereby changing the angle of the platform body.

[0011] As a further description of the above technical solution: a buffer strip is fixed to the top right side of the bottom frame, and the buffer strip is made of rubber material.

[0012] By adopting the above technical solution, the buffer strip made of rubber material has good elasticity and compressibility, which can effectively absorb and reduce the vibration and impact force caused by descending to the bottom, protect the platform body from damage, and extend the service life.

[0013] As a further description of the above technical solution: the omnidirectional angle adjustment mechanism includes a mounting member arranged at the bottom of the hollow prism, a hollow connecting disk passes through and rotates at the top of the mounting member, and the top of the hollow connecting disk is fixed to the hollow prism.

[0014] By adopting the above technical solution, the hollow connecting plate is allowed to rotate above the mounting member, and due to the fixing method of the hollow connecting plate and the hollow prism body, the angle adjustment in the horizontal direction can also be achieved.

[0015] As a further description of the above technical solution: an inner gear ring is fixed to the inner diameter of the hollow connecting disk, and a gear is meshingly connected to the inner diameter of the inner gear ring.

[0016] By adopting the above technical solution, the gear and the inner gear ring are allowed to convert or transmit rotational motion.

[0017] As a further description of the above technical solution: a driving motor is fixed at the bottom of the inner wall of the mounting member, a rotating rod is fixed at the output end of the driving motor, and the top end of the rotating rod is fixed to the gear.

[0018] By adopting the above technical solution, the driving motor is used as the driving source of the rotating rod, so that the gear is driven to rotate simultaneously during the rotation of the rotating rod.

[0019] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0020] 1.

By adjusting the angle, specific experimental conditions or working requirements can be met; in short, the vertical angle adjustment function brings higher accuracy, adaptability and flexibility to the displacement platform.

[0021] 2. The utility model provides a displacement platform with adjustable verticality and angle. Through the horizontal angle adjustment function, the platform body has multi-axis motion control capabilities and can perform precise angle adjustments in the horizontal direction. In this way, the platform body can better adapt to complex working requirements and experimental conditions.

[0022] In summary, combined with vertical angle adjustment and horizontal angle adjustment, the displacement platform can achieve all-round angle adjustment, providing greater flexibility and precision, and the combination of vertical and horizontal angle adjustment functions can better adapt to complex working environments and irregular surfaces, ensuring that the platform is always in an ideal working state; the displacement platform with vertical angle adjustment and horizontal angle adjustment can not only provide precise positioning and adaptability respectively, but also combined to provide users with a more comprehensive, flexible and precise working experience, which is suitable for various application scenarios that require high flexibility and high-precision positioning.

DETAILED DESCRIPTION

[0029] The following will refer to the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In order to further understand the content of the utility model, the utility model is described in detail with reference to the accompanying drawings.

[0031] Reference Figure 1 , 2 and Figure 4The utility model discloses a displacement platform with adjustable verticality and angle, comprising a bottom frame 1, a platform body 4 is arranged on the top of the bottom frame 1, a rotating block 11 is fixed at the bottom center of the platform body 4, a double linkage rod 10 is rotated inside the rotating block 11, a hollow prism 5 is fixed at the bottom of the bottom frame 1, a fixing plate 6 is fixed at the bottom of the inner wall of the hollow prism 5, a servo motor 7 is fixed at the front end of the fixing plate 6, a driving rod 8 is passed through and fixed at the output end of the servo motor 7, a single linkage rod 9 is fixed above the driving rod 8, and one end of the single linkage rod 9 is rotatably connected with the double linkage rod 10; an all-round angle adjustment mechanism is arranged at the bottom of the hollow prism 5; a connecting block 2 is fixed at the top left position of the bottom frame 1, connecting ears 3 are fixed at the front and rear ends of the left side of the platform body 4, and the connecting ears 3 are hingedly connected to the connecting block 2; a buffer strip 12 is fixed at the top right side of the bottom frame 1, and the buffer strip 12 is made of rubber material;

[0032] The driving rod 8 is driven to rotate through the output end of the servo motor 7, so that the single linkage rod 9 connected thereto is driven to change its angle. At the same time, one end of the single linkage rod 9 drives the double linkage rod 10 to change its angle, so that one end of the double linkage rod 10 changes its angle with the rotating block 11 as the axis point and lifts up the platform body 4, so that the vertical angle of the platform body 4 can be adjusted according to the actual usage or scene.

[0033] Reference Figure 3 and Figure 5 , the all-round angle adjustment mechanism includes a mounting member 13 arranged at the bottom of the hollow prism 5, a hollow connecting disk 131 is passed through and rotated at the top of the mounting member 13, and the top of the hollow connecting disk 131 is fixed to the hollow prism 5; an inner gear ring 132 is fixed to the inner diameter of the hollow connecting disk 131, and a gear 133 is meshed and connected to the inner diameter of the inner gear ring 132; a driving motor 134 is fixed at the bottom of the inner wall of the mounting member 13, a rotating rod 135 is fixed to the output end of the driving motor 134, and the top of the rotating rod 135 is fixed to the gear 133;

[0034] When the driving motor 134 is started, the rotating rod 135 at the output end will drive the gear 133 to rotate. Since the gear 133 and the inner ring gear 132 are in meshing connection, the inner ring gear 132 will also rotate accordingly. At the same time, the upper part of the hollow connecting disk 131 is fixed to the hollow prism body 5, and will also rotate with the hollow connecting disk 131. Therefore, the platform body 4 above can adjust the horizontal angle according to the actual usage and scene; in this way, through the control of the driving motor 134, the angle adjustment function of the all-round angle adjustment mechanism can be realized.

[0035] In addition, it should be noted that when using the displacement platform in this embodiment, the mounting member 13 is installed above the driving source for use. The driving source is mostly a guide rail, which can perform precise position displacement in one or more dimensions (usually X, Y, and Z axes). The above are all existing technologies and relatively mature technologies, so they will not be elaborated in this application.

[0036] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
