[0019] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.
[0020] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. When the number of an element is referred to as "plurality", it may be any number of two or more. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.
[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific implementations and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0022] The present invention is described in detail below in conjunction with the embodiments shown in the accompanying drawings:
[0023] A rotary lifting drive for a ceramic production fixture includes a lifting base 3, a bracket 4 that can be lifted and lowered is slidably provided on the lifting base 3, and a plurality of servo rotating components are fixedly provided on the bracket 4 at intervals. The plurality of servo rotating components can synchronously control the fixture to rotate, or individually control a certain fixture to rotate, and can control the fixture to rotate at any angle. The servos are controlled synchronously or asynchronously, and how to control is a well-known prior art in the technical field of servo motor control, which will not be described in detail here. The bracket 4 serves as a carrier to control the up and down movement of the plurality of servo rotating components relative to the lifting base 3. The bracket 4 is used to limit the spacing between the plurality of servo rotating components. During assembly, the spacing between the servo rotating components needs to be longer than the longest side of the fixture, so that the fixture will not collide during rotation.
[0024] When rotating, it will not collide with the adjacent fixtures. The tops of multiple servo rotating components are each separately provided with a centrifugal cross slider 5 for plugging into the fixture. In the prior art, the bottom of the fixture to be rotated is provided with a pluggable rotating slot (card-connecting structure). The lifting base 3 includes two groups of slider 2 support columns, and one group of slider 2 support columns includes two slider 2 support columns. Therefore, the utility model has a total of four slider 2 support columns, all of which are used to support the bracket 4. The two groups of slider 2 support columns are respectively equipped with a buffer component, which is connected to the bracket 4. The buffer component is used to make the rest of the bracket 4 more stable, avoid shaking when the servo rotating component is running, and provide support. If a separate tie rod cylinder 7 is used as both a power mechanism and a support, it is easy to be worn and loosened, because when the ceramic slurry in the mold is centrifuged, if it is offset, it will cause the bottle to be deformed. Tie rod cylinders 7 are symmetrically installed at both ends of the bracket 4, and the bracket 4 is slidably connected to the lifting base 3 through the tie rod cylinder 7.
[0025] In this embodiment, the support column of the slider 2 is provided with a linear slide rail 1 and a slider 2, the slider 2 is slidably engaged with the linear slide rail 1, the linear slide rail 1 is fixedly connected with the support column of the slider 2, the slider 2 is slidably connected with the linear slide rail 1, the slider 2 is fixedly connected with the bracket 4, and the bracket 4 is slidably connected with the support column of the slider 2 through the linear slide rail 1 and the slider 2. The opposite sides of the sliding support column are provided with the above-mentioned linear slide rails 1 and are used for sliding connection with the bracket 4. The support column of the slider 2 provides support for the bracket 4 and also improves the stability of the bracket 4 sliding up and down.
[0026] The shell of the pull rod cylinder 7 is fixedly connected to the bracket 4, and the piston rod of the pull rod cylinder 7 is fixedly connected to the lifting base 3. When it needs to rise, the piston rod pushes downward to force the bracket 4 to move upward. When the bracket 4 descends, the piston rod contracts, so the bracket 4 will move downward.
[0027] To further explain, the buffer components are symmetrically arranged at two locations near the ends of the bracket 4, and a centrifugal synchronization shaft 10 is also installed under the bracket 4. The above-mentioned buffer components are respectively installed on two different slider 2 support columns, so a centrifugal synchronization shaft 10 is required to synchronize the up and down translation of both sides of the bracket 4 to avoid the left and right sides of the bracket 4 being uneven. The buffer assembly includes a pulley 11, an arc synchronous belt 12, a synchronous belt pressure block 13 and a synchronous shaft pulley 14. The pulley 11 is rotatably connected to the support column of the slider 2. The arc synchronous belt 12 is covered and meshed with the pulley 11 and the synchronous shaft pulley 14. The synchronous belt pressure block 13 is fixedly connected to the bracket 4. The arc synchronous belt 12 is pressed on the side surface of the bracket 4 by the synchronous belt pressure block 13. The synchronous shaft pulley 14 is fixedly connected to the centrifugal synchronous shaft 10. The arc synchronous belt 12, the pulley 11 and the synchronous shaft pulley 14 are all provided with meshing teeth. In other words, a certain section of the arc synchronous belt 12 is also restricted on the bracket 4 by the above-mentioned synchronous belt pressure block 13. Therefore, the misalignment and movement that may be caused by the up and down sliding of the bracket 4 will be buffered by the meshing teeth on the arc synchronous belt 12, thereby improving the smoothness of the up and down sliding of the bracket 4.
[0028] To further elaborate, the servo rotating assembly includes a connecting shaft, the connecting shaft sleeve is provided with an origin sensing block 15, the side wall of the origin sensing block 15 is provided with a protrusion, the bracket 4 is fixedly provided with a plurality of electric eyes 16 whose number matches the servo rotating assembly, and a plurality of electric eye brackets 17 are arranged at intervals on the bracket 4, and the electric eye 16 is fixedly provided on the electric eye bracket 17. The electric eye 16 corresponds to the position of the origin sensing block 15, so as to detect the number of revolutions of the origin sensing block 15, and whenever one end of the protrusion of the origin sensing block 15 turns to the electric eye 16, it will be detected and an electrical signal will be output. Because the origin sensing block 15 is suitable for detecting the number of revolutions of the connecting shaft, the origin sensing block 15 needs to be fixedly connected to the connecting shaft, or the origin sensing block 15 needs to be interference fit with the connecting shaft.
[0029] To further explain, the servo rotating assembly also includes a mounting block 18, a bearing, a cross coupling 19, a reducer 20 and a servo motor 21; the bearing is embedded and fixedly arranged in the mounting block 18, the mounting block 18 is fixedly connected to the bracket 4, the connecting shaft passes through the bearing, the connecting shaft is rotatably connected to the mounting block 18 through the bearing, the two ends of the connecting shaft are respectively fixedly connected to the cross coupling 19 and the reducer 20, the output end of the servo motor 21 is connected to the reducer 20, the servo motor 21 is transmission-connected to the cross connecting shaft through the reducer 20, and the top of the cross coupling 19 is fixedly connected to the centrifugal cross slider 5. When the bracket 4 moves upward, the above-mentioned centrifugal cross slider 5 will be plugged into the clamping structure, and then the rotation of the servo motor 21 will cause the centrifugal cross slider 5 to rotate, so the clamp plugged into the centrifugal cross slider 5 will also rotate.
[0030] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. For ordinary technicians in this field, they can make several modifications and improvements without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
