DETAILED DESCRIPTION
[0028] The content of the utility model will be further described in detail below in combination with specific examples:
[0029] For example, Figures 1-4As shown, a six-axis table includes a first support plate 1, a second support plate 2, an adjusting plate 4 and a bearing plate 3; wherein the first support plate 1 is provided with a first mounting hole 11 for accommodating and positioning the second support plate 2, and the upper surface of the first support plate 1 is provided with a first driving device 12, and the second support plate 2 is connected with the driving end of the first driving device 12 and is completely located in the first mounting hole 11, and the first support plate 1 is driven to move along the X direction in the first mounting hole 11 by the first driving device 12, and the second support plate 2 is provided with a second mounting hole 21 for mounting the bearing plate 3, and the second driving device 22 is arranged on the side wall of the second support plate 2, and the opposite sides of the bearing plate 3 are connected with the driving end of the second driving device 22, so as to realize the movement of the second support plate 2 along the Y direction in the second mounting hole 21, and the upper surface of the bearing plate 3 is provided with a first recess 31 for mounting and fixing the adjusting plate 4, and the adjusting plate 4 is arranged in the first recess 31 through the adjusting device 5, and the adjusting plate 4 is further provided with a second recess 41, and the third driving device 6 is arranged in the second recess 41 for adjusting the rotation angle of the workbench, and the third driving device 6 can be adjusted horizontally through the adjusting device 5.
[0030] Through the cooperation of the first driving device 12 and the second driving device 22, the horizontal linear motion of the workbench in the X axis and the Y axis directions is realized; the third driving device 6 is used to drive the rotary motion of the workbench, that is, the motion in the Rz axis direction; the motion of the three voice coil motors 51 in the Z axis direction is matched, and the three voice coil motors 51 are used to make small movements at different positions, and the heights of the three movements are different, so that the workbench can be offset in different angles and directions, that is, the Rx axis and the Ry axis directions, so as to satisfy the fine adjustment of the six-axis table in six-axis directions, and achieve the flexible adjustment of the workbench in multiple dimensions. In structure, the second support plate 2 is completely nested in the first mounting hole 11, and the bearing plate 3 is also completely arranged in the second mounting hole 21, so as to avoid the simple stacking and thickness superposition between structures, effectively reduce the overall structure height, make the six-axis table device more compact, and smoothly install and run in limited space.
[0031] In this embodiment, as shown in Figures 4-5 two sides of the second support plate 2 are bent twice to form an L-shaped mounting part 23, so that the side surface of the second support plate 2 is concave, and the mounting part 23 is connected with the driving end of the first driving device 12, so that the second support plate 2 can stably move with the driving end of the first driving device 12. At the same time, the second support plate 2 is completely recessed in the first mounting hole 11, so that the overall structure is more compact and stable, and space is effectively saved, so that the six-axis table device can move in limited space.
[0032] Further, the side of the mounting portion 23 adjacent to the first support plate 1 and the side of the second driving device 22 adjacent to the first support plate 1 are not tightly attached, but have a certain gap with the inner wall surface of the first support plate 1, thereby providing a certain movement space for the mounting portion 23 and the second driving device 22, reducing the direct contact between the mounting portion 23 and the second driving device 22 and the inner wall surface of the first support plate 1 during movement, thereby reducing the possibility of collision and improving the stability and precision of movement.
[0033] As shown in Figure 4 In order to adjust the level of the workbench, the adjusting device 5 includes three voice coil motors 51 and two pneumatic counterweight devices 52, and the surface of the adjusting plate 4 is in a symmetrical trapezoidal structure, so that the adjusting plate 4 has three force application points, the three voice coil motors 51 are respectively arranged at the three force application points of the adjusting plate 4, to ensure that driving force can be directly applied to the adjusting plate 4, and the adjusting plate 4 needs to be balanced under the joint action of the three voice coil motors 51. At the same time, the two pneumatic counterweight devices 52 are located in the first groove 31 and symmetrically arranged below the adjusting plate 4, for balancing the load, the three voice coil motors 51 move slightly at different positions, and the heights of the movements of the three voice coil motors 51 are different, so that the workbench can be offset in different angles and directions, thereby adjusting the position of the product above the workbench. The driving shaft of the voice coil motor 51 directly contacts the adjusting plate 4, can directly apply the driving force of the motor to the adjusting plate 4, so that the adjusting plate 4 quickly responds to the movement instruction of the motor, realizes accurate position adjustment, meets the demand of high-precision adjustment, and the adjusting plate 4 is not fixedly connected with the voice coil motor 51, so that the adjusting plate 4 can change the angle slightly when the voice coil motor 51 moves. The driving shaft of the pneumatic counterweight device 52 is fixedly connected with the adjusting plate 4 through the fixed plate 53, can stably transmit the driving force of the pneumatic counterweight device 52 to the adjusting plate 4, ensures that the adjusting plate 4 receives uniform and stable driving force during movement, avoids shaking and deviation during movement, and reduces the large-scale adjustment of the voice coil motor 51.
[0034] Further, a plurality of mounting grooves 311 are arranged on the bottom surface of the first groove 31, and the plurality of mounting grooves 311 are respectively arranged at the mounting positions of the voice coil motors 51 and the pneumatic counterweight devices 52, which not only provides a stable mounting basis, but also ensures the accurate alignment between the motor and the adjusting plate 4, thereby realizing efficient and accurate driving force transmission. At the same time, because the mounting grooves 311 have a lower height relative to the first groove 31, when the voice coil motors 51 and the pneumatic counterweight devices 52 are mounted in the mounting grooves 311, the overall height will also be relatively reduced, thereby further reducing the height of the six-axis table.
[0035] The above examples are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and to implement it, and cannot limit the protection scope of the present application. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application, therefore, from any point of view, the examples should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
