This equipment is usually used in laboratories, biopharmaceuticals, electronic device manufacturing, and other fields that require highly clean conditions.

[0003] When processing workpieces, the existing vacuum equipment worktable mostly simply supports the workpieces through its table surface. The worktable as a whole lacks a rotating structure for rotating the workpiece, which results in a limited processing angle when the workpiece is processed on the table surface, making it difficult to meet processing requirements. For example, in the process of coating or painting the workpiece, rotation processing can achieve uniform coating distribution. If there is no rotating structure, the processing time and complexity will be increased. At the same time, the workpiece on the worktable lacks positioning processing, which is prone to deviation during processing, resulting in insufficient processing accuracy. Therefore, a vacuum equipment workpiece table rotating device is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with 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 in 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.

[0029] Example

[0030] Depend on Figure 1-Figure 3 A vacuum equipment workpiece table rotating device is provided, which mainly utilizes an electric rotating table 2 to rotatably carry the workpiece, and utilizes a positioning mechanism 7 to clamp and position the workpiece, so as to prevent the workpiece from being offset during processing and increase the processing angle of the workpiece.

[0031] In actual use, the workpiece table of the vacuum equipment lacks a rotating structure when performing rotational processing on the workpiece, which results in a limited processing angle when the workpiece is processed on the table, making it difficult to meet processing requirements. At the same time, the workpiece on the work table lacks positioning processing, which makes it easy to offset during processing, resulting in insufficient processing accuracy.

[0032] In a specific application scenario, the vacuum equipment workpiece table rotating device of the present invention is further described below in combination with the application scenario, and includes a base 1:

[0033] An electric rotating table 2 is arranged on the upper end surface of the base 1 , a main shaft 3 is connected to the output end of the electric rotating table 2 , and a rotating platform 4 is connected to the upper end surface of the main shaft 3 .

[0034] Specifically, in actual use, the user controls the rotation processing angle of the electric rotary table 2. When the workpiece is carried on the rotating platform 4, the workpiece is rotated by driving the electric rotary table 2 in cooperation with the transmission of the spindle 3. The electric rotary table 2 can make the workpiece rotate in the horizontal direction, thereby increasing the flexibility of the processing angle, which is very useful for workpieces that need to be processed or handled at multiple angles, such as cutting, grinding, coating and other processes.

[0035] Furthermore, considering that the workpiece may deviate during the rotation process, resulting in insufficient processing accuracy, a positioning mechanism 7 is also provided on the rotating platform 4 to clamp and position the workpiece; Figure 4-Figure 5 , a positioning mechanism 7 is arranged on the upper end surface of the rotating platform 4, and the positioning mechanism 7 is arranged around the center of the rotating platform 4;

[0036] The positioning mechanism 7 includes a clamping assembly 70, which includes a mounting seat 71 arranged on the upper end surface of the rotating platform 4. The mounting seat 71 is inverted U-shaped and forms a lower chamber. Two slide grooves 72 are provided on the upper end surface of the mounting seat 71. The two slide grooves 72 are respectively provided on one side of the slide rail 73 and the two are staggered. A through hole is provided at the center of the axis of the slide rail 73. The upper end surface of the mounting seat 71 is provided with a slide rail 73 along its horizontal direction. Two clamping seats 74 are slidably provided on the slide rail 73. Side seats 75 are provided on both sides of the two clamping seats 74, and a connecting spring 76 is provided between two adjacent side seats 75 on the same side.

[0037] In this embodiment, by utilizing the clamping seat 74 that slides on the slide rail 73, when the user places the workpiece to be processed between the two clamping seats 74, the two clamping seats 74 will slide in opposite directions, thereby separating the distance between them. After the workpiece is placed, the two clamping seats 74 can be pulled back by the connecting springs 76 arranged on both sides, and then the clamping and positioning of the workpiece is completed by the clamping of the two clamping seats 74.

[0038] In more detail, considering the different sliding distances between the two clamping seats 74 when the workpiece is placed, in order to better clamp the workpiece synchronously, a synchronization component 701 is also provided below the two clamping seats 74 for synchronously connecting the workpiece. Figure 6 The positioning mechanism 7 also includes a synchronization component 701, which includes a positioning shaft 711 arranged in the through hole; the positioning shaft 711 vertically penetrates the slide rail 73 and extends to the lower chamber of the mounting seat 71, and a bearing member is provided on the outside of the positioning shaft 711, and a positioning gear 712 is provided on the outside of the bearing member; the synchronization component 701 also includes a connecting plate 79 arranged on the lower end surface of the clamping seat 74, and a rack 710 is provided on the lower end surface of the connecting plate 79, and the two racks 710 are arranged in an opposite and staggered manner; the positioning gear 712 is arranged between the two racks 710 and is meshed with the two racks 710 at the same time.

[0039] In this embodiment, when the workpiece is placed between the two clamping seats 74, the two clamping seats 74 will be stretched apart by the length of the workpiece, and then the clamping seats 74 will move and drive the connecting plate 79 to move, and the movement of the connecting plate 79 will drive the rack 710 to move radially. Due to the rotation of the positioning gear 712 and the meshing between the two racks 710, the two racks 710 will move synchronously when moving, and finally drive the two clamping seats 74 to move synchronously and clamp the workpiece.

[0040] More preferably, considering that the vacuum environment needs to be ensured during processing and the workpiece clamping stability is further improved, a first push rod motor 5 and a second push rod motor 6 are further provided on one side of the positioning mechanism 7 for controlling the positioning mechanism 7. Figure 1-Figure 3As shown in FIG. 1 , the first push rod motor 5 and the second push rod motor 6 are arranged on the upper end surface of the rotating platform 4 , a connecting shaft 77 is arranged on one side of a clamp seat 74 , and a limiting plate 78 is fixedly arranged on the other side of the connecting shaft 77 .

[0041] In a specific preferred embodiment, Figure 1-Figure 3 As shown in, by controlling the output end of the first push rod motor 5 to extend forward and fit with the inner wall of the limiting plate 78, by controlling the output end of the first push rod motor 5 to move backward, the limiting plate 78 can be pulled by its output end, and through the movement of the limiting plate 78, one of the clamping seats 74 can be driven to move, and then under the synchronous drive of the synchronization component 701, the automatic opening between the two clamping seats 74 is realized, so that the workpiece can be placed between the two clamping seats 74. With the rotation of the rotating platform 4, when the positioning mechanism 7 that clamps the workpiece is transferred to one side of the second push rod motor 6, the output end of the second push rod motor 6 is controlled to advance forward, so that the end of the set second push rod motor 6 can push the limiting plate 78, so that the two clamping seats 74 can be squeezed by the output end of the second push rod motor 6, so as to better clamp the workpiece.

[0042] Further preferably, by programming and controlling the push-out and retraction of the output ends of the first push rod motor 5 and the second push rod motor 6 and coordinating the rotation cycle of the rotating platform 4, it is also possible to automatically complete the clamping and releasing of the workpiece by controlling the first push rod motor 5 and the second push rod motor 6 and coordinating with the positioning mechanism 7.

[0043] Further, it can be understood that the matching of the rotation numbers of the first push rod motor 5, the second push rod motor 6 and the positioning mechanism 7, as well as the automated control circuit between the three can be achieved through simple programming by technicians in this field, which is common knowledge in this field, so the control method and circuit connection will not be described in detail.

[0044] Working principle:

[0045] The first step: When the user is positioning the workpiece, the workpiece is placed between the two clamping seats 74. The length of the workpiece is stretched out by the two clamping seats 74. Then the clamping seat 74 moves and drives the connecting plate 79 to move. The movement of the connecting plate 79 drives the rack 710 to move radially. Due to the rotation of the positioning gear 712 and the meshing between the two racks 710, the two racks 710 move synchronously when moving, and finally drive the two clamping seats 74 to move synchronously and clamp the workpiece. After the workpiece is clamped, the two clamping seats 74 can be further stretched by the connecting spring 76 to ensure that the workpiece is stably clamped.

[0046] Step 2: The user controls the rotation processing angle of the electric rotary table 2. When the workpiece is carried on the positioning mechanism 7, the electric rotary table 2 is driven by the set electric rotary table 2 and cooperates with the transmission of the spindle 3, so that the electric rotary table 2 can rotate the workpiece in the horizontal direction, and finally the set rotating platform 4 can rotate and carry the workpiece.

[0047] 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.
