[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0040] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0042] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0043] This embodiment provides an adjusting device for adjusting the position of a workpiece, such as Figure 1-Figure 3As shown, the device mainly includes a platform 10, a first driving mechanism 20, a second driving mechanism 30 and a rotating member 40; wherein the top surface of the platform 10 is used to install the workpiece, and the edge of the platform 10 is opened to form a limiting groove 11; the first driving mechanism 20 is arranged at the bottom of the platform 10 and is pivotally connected to the platform 10; the second driving mechanism 30 is arranged at the bottom of the platform 10 and is located on the side of the first driving mechanism 20 close to the limiting groove 11; the rotating member 40 is arranged on the second driving mechanism 30 and is movably arranged in the limiting groove 11; when the first driving mechanism 20 and the second driving mechanism 30 move at the same speed and in the same direction, they can drive the platform 10 to move synchronously; when relative motion occurs between the first driving mechanism 20 and the second driving mechanism 30, the rotating member 40 can abut the inner wall of the limiting groove 11 and drive the platform 10 to rotate around the pivot position.

[0044] In this device, a plurality of mounting grooves 12 are provided on the platform 10, and the plurality of mounting grooves 12 can improve the convenience and stability of installing the workpiece; moreover, when the first driving mechanism 20 and the second driving mechanism 30 move at the same speed and in the same direction, the platform 10 can drive the product to move together, thereby realizing horizontal movement; and when the first driving mechanism 20 is stationary and the second driving mechanism 30 moves, relative movement occurs between the two, and the rotating member 40 will follow the movement of the second driving mechanism 30, and then can abut against the inner wall of the limiting groove 11, and the platform 10 is pivotally connected to the first driving mechanism 20, so the abutment force between the rotating member 40 and the limiting groove 11 can drive the platform 10 to rotate a certain angle around the pivot position. Therefore, the device is not only simple in overall structure and easy to operate, but can also drive the product to move horizontally, and can also rotate the product around the vertical direction to a preset angle, thereby ensuring the operation accuracy.

[0045] Specifically, Figure 2 As shown, the rotating member 40 is a transmission double roller bearing, which includes a first roller portion 41 and a second roller portion 42 arranged in a vertical direction, and the first roller portion 41 and the second roller portion 42 can rotate relative to each other. The transmission double roller bearing has a higher load-bearing capacity and a higher structural strength; at the same time, the symmetrically arranged first roller portion 41 and the second roller portion 42 have a good clearance elimination effect.

[0046] Correspondingly, such as Figure 2As shown, the inner wall of the limiting groove 11 close to the second driving mechanism 30 is designed with a first protrusion 111, and the inner wall of the limiting groove 11 away from the second driving mechanism 30 is provided with a second protrusion 112; when the first driving mechanism 20 and the second driving mechanism 30 generate relative motion, the first roller part 41 can abut against the first protrusion 111, or the second roller part 42 can abut against the second protrusion 112, so that the platform 10 can rotate clockwise or counterclockwise around the pivot position (from the perspective of looking down at the platform 10). This arrangement is not only simple in structure, but also has a clear division of labor. When the platform 10 needs to be rotated clockwise, it is only necessary to abut the first protrusion 111 through the first roller part 41, otherwise, the platform 10 is driven to rotate counterclockwise. When the rotation in one direction is not smooth, it is only necessary to check and replace the corresponding parts.

[0047] It should be noted that when the first roller portion 41 abuts against the first protrusion 111, a rotation gap can be formed between the second roller portion 42 and the second protrusion 112, thereby providing a certain space for the rotation of the platform 10; conversely, when the second roller portion 42 abuts against the second protrusion 112, a rotation gap can be formed between the first roller portion 41 and the first protrusion 111, thereby providing a certain space for the rotation of the platform 10.

[0048] In addition, the first drive mechanism 20 and the second drive mechanism 30 can only extend in the first direction or the second direction, so the platform 10 can rotate at a relatively small angle (the angle of rotation in the clockwise or counterclockwise direction does not exceed 3°). In this embodiment, the rotation accuracy of the platform 10 around the pivot position is ±0.003°, thereby further improving the operation accuracy.

[0049] Specifically, Figure 1 As shown, the first driving mechanism 20 includes a first driving member 21 and a first carrier plate 22, the first carrier plate 22 is connected to the output end of the first driving member 21, a rotating member 23 is arranged on the first carrier plate 22, and the platform 10 is pivotally connected to the rotating member 23. The first carrier plate 22 is arranged at a preset position and then connected to the platform 10, which can effectively improve the stability of the platform 10. The rotating member 23 is arranged on the first carrier plate 22 to improve the convenience of installing the platform 10 and ensure good rotation ability.

[0050] It should be noted that, in this embodiment, the rotating member 23 is a cross roller bearing. This bearing can simultaneously withstand large radial loads, axial loads, and overturning moments (multi-directional composite loads), and has good rigidity, high rotation accuracy, and long service life. By installing a cross roller bearing on the first carrier plate 22, the load-bearing weight of the platform 10 can be greatly increased, thereby improving the scope of use of the device.

[0051] In addition, if Figure 1As shown, the second driving mechanism 30 includes a second driving member 31 and a second carrier plate 32, the second carrier plate 32 is connected to the output end of the second driving member 31, and the rotating member 40 is pivotally connected to the second carrier plate 32. This arrangement can simplify the overall structure, improve the convenience of installing the second driving mechanism 30, and also facilitate the installation of the rotating member 40 on the second carrier plate 32, and improve the stability of the rotating member 40 when driving the platform 10 to rotate, thereby improving the user experience.

[0052] It should be noted that the first driving member 21 and the second driving member 31 are both roller screws, which have high transmission efficiency, low friction resistance, low wear resistance, high axial strength, high driving accuracy and repeated positioning accuracy, which helps to improve the rotation accuracy of the platform 10. Figure 1 As shown, the device also includes a fixing seat 60, and the first driving member 21 and the second driving member 31 are both installed on the fixing seat 60 to improve the stability of the overall structure; the output end of the first driving member 21 is connected to the first driving block 25, and the output end of the second driving member 31 is connected to the second driving block 34. The first driving block 25 and the second driving block 34 are respectively provided with a first guide rod 24 and a second guide rod 33, one end of the first guide rod 24 and the second guide rod 33 are respectively connected to the first bearing plate 22 and the second bearing plate 32, and the other end is penetrated into the guide hole of the fixing seat 60; when the first When the output ends of the driving member 21 and the second driving member 31 are extended or retracted, they respectively drive the first driving block 25 and the second driving block 34 to move. The first driving block 25 drives the first carrying plate 22 to move along the first or second direction through the first guide rod 24. The second driving block 34 drives the second carrying plate 32 to move along the first or second direction through the second guide rod 33. At the same time, the first guide rod 24 and the second guide rod 33 move in the guide hole, which can play a good guiding role, thereby ensuring that the first carrying plate 22 and the second carrying plate 32 can always move along the first or second direction, thereby improving the adjustment accuracy.

[0053] To improve mobility efficiency, Figure 3 As shown, a sliding assembly 50 is provided on the side of the first carrier plate 22 and the second carrier plate 32 facing away from the platform 10, so that the first carrier plate 22 and the second carrier plate 32 can slide along a preset direction. By providing the sliding assembly 50, not only can the first carrier plate 22 and the second carrier plate 32 be supported, and the radial load of the roller screw can be reduced, but also the sliding smoothness of the first carrier plate 22 and the second carrier plate 32 can be ensured, thereby improving the moving efficiency.

[0054] Specifically, Figure 3As shown, the sliding assembly 50 includes a slide rail 51 and a slider 52. The slide rail 51 is arranged on the support surface and extends along the output direction of the first driving member 21 or the second driving member 31 (that is, parallel to the first direction or the second direction). The first carrier plate 22 and the second carrier plate 32 are both provided with a slider 52, and the slider 52 is slidably connected to the slide rail 51. The slide rail 51 is arranged on the support surface to improve the stability during the sliding process. The slider 52 is arranged at the bottom ends of the first carrier plate 22 and the second carrier plate 32, which can not only simplify the overall structure, but also ensure the sliding effect of the first carrier plate 22 and the second carrier plate 32.

[0055] It should be noted that a plurality of sliding assemblies 50 are arranged in parallel and at intervals, and each slide rail 51 is slidably connected to a plurality of sliders 52, which further improves the sliding effect and the stability of the sliding. In addition, since the area of ​​the second carrier plate 32 is small and does not need to support the platform 10, only one sliding assembly 50 is provided.

[0056] Based on the above adjustment device, this embodiment also provides a position adjustment method, which specifically includes the following steps:

[0057] S100, connecting the workpiece to the mounting groove 12 through a fixture, and then mounting it on the platform 10;

[0058] S200, start the first driving mechanism 20 and the second driving mechanism 30, and make the output ends of the two move at the same speed and in the same direction, so as to drive the platform 10 to move to the preset position (that is, the movement amount of the first carrier plate 22 is X1 and the movement amount of the second carrier plate 32 is X2, X1 and X2 are equal in size, direction and movement speed, so that the horizontal movement distance of the platform 10 is X=X1=X2);

[0059] S300, close the first driving mechanism 20, continue to open the second driving mechanism 30, so that the two produce relative movement, the second driving mechanism 30 drives the rotating member 40 to abut the inner wall of the limiting groove 11, so that the platform 10 can rotate around the pivot position by a preset angle (that is, the rotation angle α of the platform 10 is determined by the relative displacement of X1 and X2).

[0060] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
