Abstract
Description
Technical Field
[0001] The utility model relates to a rotary workbench and belongs to the technical field of adjustable tool supports. Background Art
[0002] In the field of machining, especially in situations where high-precision, multi-angle machining is required, the five-axis rotary table has been widely used because it can provide five degrees of freedom. However, for some specific applications or small businesses, the high cost and long delivery cycle of the five-axis rotary table have become bottlenecks restricting its use.
[0003] At present, the four-axis rotary table has become a common solution due to its relatively simple structure and low cost. However, with the increasing complexity of processing requirements, especially when it is necessary to process positions on multi-angle planes, the limitations of the four-axis rotary table have gradually become apparent. Due to the lack of a vertical rotation axis, the four-axis rotary table cannot achieve precise control of certain specific angles during the processing process, which limits its application in some high-precision processing fields. Utility Model Content
[0004] The purpose of the utility model is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.
[0008] Further, the horizontal support assembly includes a relatively arranged horizontal lower limit column and a relatively arranged horizontal upper limit column, the lower end surface of the horizontal lower limit column and the upper end surface of the horizontal upper limit column are both planes, the horizontal lower limit column is installed on the base plate, and the horizontal upper limit column is installed on the rotating plate; the inclined support assembly includes a relatively arranged inclined lower limit column and an inclined upper limit column, the lower end surface of the inclined upper limit column is an inclined surface, and the upper end surface of the inclined lower limit column is a plane, the inclined lower limit column is installed on the base plate, and the inclined upper limit column is installed on the rotating plate.

When the rotating plate is tilted to a certain angle, the inclined surface of the inclined upper limit column is fit with the plane of the inclined lower limit column in the horizontal direction, so that the rotating plate can remain stable in the inclined direction.
[0010] Furthermore, the inclination angle α of the lower end surface of the inclined upper limit post has a value range of 0° to 15°.

[0014] The beneficial effect of adopting the above further scheme is that when the piston rod of the first driving cylinder extends upward, the piston rod of the first driving cylinder fits with the lower end surface of the first piston top block, and the piston rod can accurately fit with the inclined surface of the lower end surface of the first piston top block, ensuring that the piston rod can smoothly push the rotating plate through the first piston top block.
[0015] Furthermore, it also includes a second piston top block, which is mounted on the rotating plate and located above the second driving cylinder, and the lower end surface of the second piston top block is a plane.
[0016] The beneficial effect of adopting the above further solution is that when the piston rod of the second driving cylinder extends upward, the piston rod of the second driving cylinder fits against the lower end surface of the second piston top block, ensuring that the piston rod can smoothly push the rotating plate through the second piston top block.

[0020] The beneficial effect of adopting the above-mentioned further scheme is that the first dustproof telescopic cover can effectively prevent dust, particles and other impurities in the external environment from entering the interior of the horizontal support assembly. Since the direct contact between dust and impurities is reduced, the friction and wear of the horizontal support assembly will also be reduced accordingly, thereby improving the reliability and stability of the equipment.
[0021] Furthermore, it also includes a second dustproof telescopic cover, and the second dustproof telescopic cover is arranged outside the inclined support assembly.
[0022] The beneficial effect of adopting the above-mentioned further scheme is that the second dustproof telescopic cover can effectively prevent dust, particles and other impurities in the external environment from entering the interior of the tilt support assembly.

DETAILED DESCRIPTION
[0035] The principles and features of the present invention are described below in conjunction with examples. The examples are only used to explain the present invention and are not used to limit the scope of the present invention.
[0036] like Figure 1-6As shown, a rotating workbench includes a base plate 1, a rotating plate 2, a first driving cylinder 3, a second driving cylinder 4, a horizontal support assembly 5 and a tilting support assembly 6. The rotating plate 2 is hinged above the base plate 1 by a hinge pin 12. The rotating plate 2 can tilt relative to the base plate 1 around a hinge point. The two sides of the hinge point are a horizontal support side 21 and a tilting support side 22 respectively. The first driving cylinder 3 and the tilting support assembly 6 are arranged on the tilting support side 22. The second driving cylinder 4 and the horizontal support assembly 5 are arranged on the horizontal support side 21. The horizontal support assembly 5 is used to keep the rotating plate 2 in a horizontal state after the first driving cylinder 3 lifts one end of the rotating plate 2. The tilting support assembly 6 is used to keep the rotating plate 2 in a tilted state after the second driving cylinder 4 lifts the other end of the rotating plate 2.
[0037] More specifically, the first drive cylinder 3, the second drive cylinder 4, the horizontal support assembly 5 and the inclined support assembly 6 are respectively located at the four corners of the base plate 1, the inclined support assembly 6 and the second drive cylinder 4 are diagonally arranged, and the horizontal support assembly 5 and the first drive cylinder 3 are diagonally arranged.
[0038] The horizontal support assembly 5 includes a relatively arranged horizontal lower limit column 51 and a relatively arranged horizontal upper limit column 52, the lower end surface of the horizontal lower limit column 51 and the upper end surface of the horizontal upper limit column 52 are both planes, the horizontal lower limit column 51 is installed on the base plate 1, and the horizontal upper limit column 52 is installed on the rotating plate 2; the inclined support assembly 6 includes a relatively arranged inclined lower limit column 61 and an inclined upper limit column 62, the lower end surface of the inclined upper limit column 62 is an inclined surface, and the upper end surface of the inclined lower limit column 61 is a plane, the inclined lower limit column 61 is installed on the base plate 1, and the inclined upper limit column 62 is installed on the rotating plate 2.
[0039] The embodiment of the utility model does not limit the inclination angle of the lower end face of the inclined upper limit positioning column 62. The inclination angle α of the lower end face of the inclined upper limit positioning column 62 has a value range of 0° to 15°, preferably 5° to 10°. As long as the processing requirements are met, it should be within the protection scope of the utility model.
[0040] The cylinder bodies of the first driving cylinder 3 and the second driving cylinder 4 are both fixed on the base plate 1 .
[0041] The rotary workbench further includes a first piston top block 7, which is mounted on the rotary plate 2 and is located above the first drive cylinder 3, and the lower end surface of the first piston top block 7 is an inclined surface. The rotary workbench further includes a second piston top block 8, which is mounted on the rotary plate 2 and is located above the second drive cylinder 4, and the lower end surface of the second piston top block 8 is a plane. When the piston rod of the first drive cylinder 3 extends upward, the piston rod of the first drive cylinder 3 fits with the lower end surface of the first piston top block 7. When the piston rod of the second drive cylinder 4 extends upward, the piston rod of the second drive cylinder 4 fits with the lower end surface of the second piston top block 8.
[0042] The rotary workbench further comprises a first dustproof telescopic cover 9, and the first dustproof telescopic cover 9 is disposed on the outer surface of the horizontal support assembly 5. The rotary workbench further comprises a second dustproof telescopic cover 10, and the second dustproof telescopic cover 10 is disposed on the outer surface of the tilt support assembly 6.
[0043] In this embodiment, the first drive cylinder 3 and the second drive cylinder 4 are both hydraulic cylinders. The working method of the rotary workbench of the utility model is as follows:
[0044] like Figure 2 - Figure 4 As shown, when the high-pressure oil enters the oil cylinder of the first drive cylinder 3 and the oil cylinder of the second drive cylinder 4 is discharging oil, the piston rod in the first drive cylinder 3 gradually moves upward, and the piston rod in the second drive cylinder 4 gradually moves downward. When the piston rod in the first drive cylinder 3 contacts the first piston top block 7, it will push the rotating plate 2 to rotate around the hinge pin 12 toward the horizontal support side 21. As the rotating plate 2 rotates, the horizontal upper limit column 52 and the horizontal lower limit column 51 gradually approach and finally contact. The contact of these two limit columns limits the further rotation of the rotating plate 2. At this time, the piston rod of the first drive cylinder 3 stops moving upward, and the rotating plate 2 stops at this position. Since the height of the contact surface between the horizontal upper limit column 52 and the horizontal lower limit column 51 is the same as the center position of the hinge shaft, under the joint support of the piston rod of the first drive cylinder 3, the horizontal upper limit column 52 and the horizontal lower limit column 51, the rotating plate 2 can be stably maintained in this horizontal state. In this horizontal position, all forces acting on the rotating plate 2 (mainly the thrust from the piston rod of the first drive cylinder 3 and the reaction force between the horizontal upper limit column 52 and the horizontal lower limit column 51) are in a balanced state, so the rotating plate 2 will not move or rotate by itself.
[0045] like Figure 5 and Figure 6As shown, when the high-pressure oil enters the oil cylinder of the second drive cylinder 4 and the oil cylinder of the first drive cylinder 3 is discharging oil, the piston rod in the second drive cylinder 4 gradually moves upward, and the piston rod in the first drive cylinder 3 gradually moves downward. When the piston rod in the second drive cylinder 4 contacts the second piston top block 8, it will push the rotating plate 2 to rotate around the hinge pin 12 toward the tilting support side 22 until the tilting upper limit column 62 touches the tilting lower limit column 61, and the inclined surface of the lower end of the tilting upper limit column 62 contacts the plane of the tilting lower limit column 61 to form a limit. At this time, the piston rod of the second drive cylinder 4 stops moving upward, and the rotating plate 2 stops at this tilted position. The tilt angle β of the rotating plate 2 is equal to the tilt angle α of the lower end surface of the tilting upper limit column 62. Under the joint support of the piston rod of the second drive cylinder 4, the tilting upper limit column 62 and the tilting lower limit column 61, the rotating plate 2 can stably remain in this tilted state.
[0046] like Figure 7 and Figure 8 As shown, the rotary workbench further includes a turntable 11, and the turntable 11 is fixed above the turntable 2. When the turntable 2 is horizontal, the turntable 11 can be supported to work in a horizontal state, and when the turntable 2 is tilted, the turntable 11 can be supported to work in a tilted state.
[0047] The traditional way of achieving five-axis machining capabilities often requires large-scale modification or replacement of the existing four-axis turntable 11, which not only greatly increases the complexity and manufacturing cost of the equipment, but also may have an adverse effect on the stability and precision of the equipment. In contrast, the rotary worktable of the utility model can increase the degree of freedom of the turntable 11 and improve the machining capacity of the turntable 11 on the basis of retaining the basic structure of the original turntable 11, which not only simplifies the equipment structure and reduces the manufacturing cost, but also maintains the stability and precision of the equipment.
[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
