Technical Field
[0001] This utility model relates to the field of casting auxiliary equipment, and in particular to a rotary worktable for a casting machine. Background Technology
[0002] In the casting production field, multiple casting machines are often needed to cast castings simultaneously. Currently, commonly used casting machines are usually configured with one station, that is, only one worktable for placing molds or carrying workpieces. During the casting process, only one mold can be processed. After the casting liquid is injected into the mold, the casting machine is usually in standby mode and must wait for the casting to be completed before the next injection operation can be performed. This method is inefficient. Therefore, there is an urgent need to provide a rotating worktable for casting machines to solve the above problems. Summary of the Invention

[0005] The rotating platform is provided with several workstations, and the rotating platform is connected to the drive mechanism. The rotating platform is mounted on the base.
[0006] The support assembly is located below the rotary table. The support assembly includes a support base, a support plate, a connecting seat, and rollers. The rollers are rotatably connected to the connecting seat. The connecting seat is located on the support plate. The support plate is located on the support base. The rollers are in contact with the lower surface of the rotary table.

Finished workpieces can also be transferred to the next processing area via the multiple workstations of the rotary table, effectively improving casting and production efficiency. The drive mechanism facilitates automated casting production, enabling the rotary table to rotate to the corresponding workstation automatically for easy workpiece handling, further improving efficiency and reducing labor costs, while also avoiding the health risks associated with high-temperature environments.

[0028] To explain in detail the technical content, structural features, objectives, and effects of the technical solution, the following description is provided in conjunction with specific embodiments and accompanying drawings.
[0029] like Figures 1 to 5 As shown, this embodiment provides a casting machine rotary table, including: a rotary table 1, a drive mechanism, a base 3, and several support components 4;
[0030] The rotary table 1 is provided with several workstations 101. The rotary table 1 is connected to the drive mechanism and is located on the base. In this embodiment, the rotary table 1 can be circular or regular polygonal. During the casting process, multiple molds can be placed on the rotary table 1. After the casting machine completes one pour, the part can be taken out again and the next pouring operation can be carried out without waiting for the previous mold to cool down. The castings after casting can also be transferred to the next processing area through the rotary table 1. In addition, different processing equipment, such as grinding machines and cutting machines, can be set around the rotary table 1 to improve the efficiency of casting production and processing.
[0031] like Figure 2 and Figure 3 As shown, the drive mechanism can be a drive motor 201, a reducer 202 and a bearing 203. The drive motor 201 is connected to the reducer 202 in a transmission connection. The outer bearing 2031 of the bearing 203 is fixedly connected to the rotary table 1. A gear is provided or fixedly sleeved on the outer circumference of the outer bearing 2031. The gear is connected to the output end of the reducer 202 in a transmission connection. The inner bearing 2032 of the bearing is fixedly connected to the base.
[0032] In the above embodiment, the axis of the rotary table 1 is located on the base 3. When there are many workpieces on the rotary table 1 or it is biased to one side, its stability cannot be guaranteed. Therefore, in this embodiment, if... Figure 2 , Figure 4 and Figure 5 As shown, by providing several support components 4 below the rotary table 1, the stability of the rotary table 1 is effectively improved. Specifically, the support components 4 are located below the rotary table 1 and include a support base 401, a support plate 402, a connecting seat 403, and rollers 404. The rollers 404 are rotatably connected to the connecting seat 403, which is located on the support plate 402. The support plate 402 is located on the support base 401, and the rollers 404 are in contact with the lower surface of the rotary table 1. That is, the support components 4 provide support force to the rotary table 1, and the rollers 404 facilitate the rotation of the rotary table 1. In some embodiments, several height adjustment bolts 405 are provided between the support base 401 and the support plate 402; that is, when it is necessary to adjust the height of the rollers 404, it can be adjusted by adjusting the bolts, which is convenient for operation.
[0033] like Figure 1 As shown, in order to facilitate the connection of multiple pipelines, a rotary coupling 102 can also be provided at the axis of the rotary table 1 in this embodiment.
[0034] In the above embodiments, in order to improve the stability of the rotary table 1 and the contact area between the roller 404 and the rotary table 1, in this embodiment, as follows: Figure 5As shown, a plurality of spacer plates 406 are fixedly provided on the connecting seat 403. The spacer plates are arranged in parallel. Rollers 404 are rotatably disposed between two connected spacer plates 406 and can be connected to the connecting seat 403 by means of pins 408, thus allowing multiple sets of rollers 404 to be provided. In order to avoid interference between the rollers 404 and the spacer plates 406 and to reduce friction, spacer rings 407 can also be provided on both sides of the rollers 404 and between them and the spacer plates 406.
[0035] like Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the rotary table of this casting machine further includes a centering component 5. The centering component 5 includes a fixed plate 501, a moving plate 504, a centering bearing 505, and a moving rod 506. The fixed plate 501 is provided with a first through hole 502. The fixed end of the moving rod 506 is connected to the fixed plate 501, and the telescopic end passes through the first through hole 502 and is connected to one side of the moving plate 504. The moving rod can be a hydraulic cylinder. The centering bearing 505 is rotatably located on the other side of the moving plate 504. A centering block 601 is provided below the rotary table 1, and a centering groove 602 adapted to the centering bearing 505 is provided on the centering block 601. In this embodiment, by setting the centering component 5 and the centering groove 602 below the rotary table 1, it is convenient to correct the rotation angle of the rotary table 1, avoiding the rotation angle error of the rotary table 1, which would cause the mold or workpiece on the station 101 of the rotary table 1 to not reach the predetermined position.
[0036] In the above embodiments, to improve the telescopic stability of the moving bar 506 and the connectivity between the moving plate 504 and the fixed plate 501, in some embodiments, the centering assembly 5 further includes a column guide bushing 507. The fixed plate 501 has a second through hole 503. The outer bushing 5071 of the column guide bushing 507 is fixedly connected to the fixed plate 501, and the inner column of the column guide bushing 507 passes through the second through hole 503 and is connected to one side of the moving plate 504. That is, a column guide bushing 507 can be provided on both sides of the moving bar 506 to guide and improve stability. In addition, in different embodiments, a proximity switch 508 can also be fixedly provided on one side of the fixed plate 501 to facilitate the detection and control of whether the centering block 601 has reached the correct position.
[0037] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of patent protection for this utility model.
