Description

Technical Field

[0001] This utility model relates to the field of casting technology, and in particular to an automatic core assembly device. Background Technology

[0002] In the casting industry, some sand cores are composed of multiple sub-sand cores. When assembling sand cores, manual assembly or robotic assembly can be used. However, for some cylindrical or conical sand cores, when these sand cores are composed of multiple sub-sand cores, robotic assembly can only assemble multiple sand cores sequentially from the outside, which is not efficient enough and can easily damage the outer surface of the sand cores, resulting in low adaptability. Utility Model Content

[0003] This utility model provides an automatic core assembly device, including a base plate, a fixing plate fixedly mounted on the base plate, a plurality of guide grooves radially arranged on the fixing plate, a sand core positioning component movably mounted in the guide grooves, a rotating disk mounted on the base plate, the rotating disk being rotatable relative to the base plate, the rotating disk being connected to a drive mechanism, a plurality of arc-shaped sliding grooves being provided on the rotating disk, the arc-shaped sliding grooves extending arc-shaped from one end near the center of the rotating disk to the direction away from the center of the rotating disk, the sand core positioning component movably mounted in the arc-shaped sliding grooves, and the sand core positioning component having a sand core positioning block.

[0004] In an optional embodiment, the sand core positioning assembly includes a connecting rod that is slidably disposed within an arcuate groove of the rotating disk.

[0005] In an optional implementation, the outer surface of the connecting rod is circular.

[0006] In an optional embodiment, the core positioning assembly includes a slider that is slidably disposed within a guide groove of a fixed plate.

[0007] In an optional embodiment, at least two sand core positioning blocks are provided longitudinally on the inner side of the sand core positioning assembly.

[0008] In an optional embodiment, the sand core positioning block includes a positioning boss and a positioning post, with the positioning post located on the positioning boss and used to insert the sub-sand core.

[0009] In an optional embodiment, a fixed plate is disposed above a base plate, and a rotating disk is disposed between the base plate and the fixed plate.

[0010] In an optional embodiment, a support column is provided between the fixed plate and the base plate, and the support column is located on the outside of the rotating disk.

[0011] In an optional implementation, the guide groove extends through the fixed plate, and the sand core positioning assembly passes through the guide groove and connects to the arc-shaped slide.

[0012] In an optional embodiment, the driving element is a cylinder, and a transmission mechanism is provided between the cylinder and the rotary disk.

[0013] The automatic core assembly device provided by this utility model has the following advantages: the guide groove of the fixed plate restricts multiple sand core positioning components to only approach or move away from each other along the guide groove. The rotating disk drives the sand core positioning components through the arc-shaped sliding groove. When the rotating disk rotates, the sand core positioning components move in the arc-shaped sliding groove. Due to the restriction of the guide groove, the sand core positioning components can only approach or move away from each other along the guide groove. Therefore, this utility model can complete the assembly of sand cores of cylindrical and conical rotating bodies by driving the rotating disk to rotate with only one drive mechanism. The structure is simple and the cost is low. Attached Figure Description

[0023] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] This utility model embodiment provides an automatic core assembly device, such as... Figures 1 to 6 As shown, the device includes a base plate 100, on which a fixing plate 200 is fixedly mounted. The fixing plate 200 has a plurality of radially arranged guide grooves 210. A sand core positioning assembly 300 is movably disposed within the guide grooves 210. The base plate 100 also has a rotating disk 400, which can rotate relative to the base plate 100. The rotating disk 400 is connected to a drive mechanism 500. The rotating disk 400 has a plurality of arc-shaped sliding grooves 410. The arc-shaped sliding grooves 410 extend arcuately from one end near the center of the rotating disk 400 to the direction away from the center of the rotating disk 400. The sand core positioning assembly 300 is movably disposed within the arc-shaped sliding grooves 410. The sand core positioning assembly 300 has a sand core positioning block 310.

[0025] in, Figure 1 This is a schematic diagram of the overall structure of the automatic core assembly device provided in an embodiment of the present utility model. Figure 2 This is a schematic diagram of the structure of the sand core positioning component 300 in the automatic core assembly device provided in this embodiment of the utility model. Figure 3 This is a top view schematic diagram of the automatic core assembly device provided in an embodiment of the present utility model. Figure 4 This is a schematic diagram of the automatic core assembly device provided in this embodiment of the present invention with the fixing plate 200 removed, exposing the structure of the rotating disk 400. Figure 5 This is one of the usage states of the automatic core assembly device provided in this embodiment of the utility model. This state is before core assembly. Figure 6 This is the second schematic diagram of the automatic core assembly device provided in this embodiment of the present invention, showing the state in which core assembly is completed.

[0026] like Figure 5 As shown, firstly, the rotating disk 400 is rotated to a position where the multiple sand core positioning components 300 are relatively far apart, fixing the sub-sand core 800 using the sand core positioning components 300. Then, the drive element is activated, driving the rotating disk 400 to rotate. Since the sand core positioning components 300 are movably disposed within the arc-shaped groove 410, when the rotating disk 400 rotates, the arc-shaped groove 410 also rotates. However, because the sand core positioning components 300 are also movably disposed within the guide groove 210, they are restricted by the guide groove 210, allowing them to move only along the direction of the guide groove 210. Since the arc-shaped groove 410 extends arc-shaped from one end near the center of the rotating disk 400 towards the direction away from the center, the sand core positioning components 300 move within the guide groove 210 as the arc-shaped groove rotates. Finally, as... Figure 6As shown, multiple sand core positioning components 300 drive the sub-sand cores 800 to close together, completing the core assembly action.

[0027] The automatic core assembly device provided in this embodiment can complete the assembly of sand cores of cylindrical and conical shapes by driving the rotating disk 400 to rotate using only one drive mechanism 500. It has a simple structure and low cost.

[0028] In some embodiments, such as Figure 2 As shown, the sand core positioning assembly 300 includes a connecting rod 320, which is slidably disposed within the arc-shaped groove 410 of the rotating disk 400. Preferably, the outer surface of the connecting rod 320 is circular. Figure 2 As shown, a longitudinal limiting mechanism can also be set on the connecting rod 320 to achieve longitudinal limiting of the connecting rod 320 and the rotating disk 400.

[0029] In some embodiments, such as Figure 2 and Figure 3 As shown, the sand core positioning assembly 300 includes a slider 330, which is slidably disposed within the guide groove 210 of the fixed plate 200. Figure 2 As shown, the slider 330 can also be equipped with a longitudinal limiting mechanism to achieve longitudinal limiting between the slider 330 and the guide groove 210 of the fixed plate 200.

[0030] like Figure 2 As shown, in some embodiments, two sand core positioning blocks 310 are provided longitudinally on the inner side of the sand core positioning assembly 300. In some embodiments, the sand core positioning assembly 300 has only one sand core positioning block 310. In some embodiments, the sand core positioning assembly 300 has three or more sand core positioning blocks 310. The inner side of the sand core positioning assembly 300 refers to... Figure 1 The inner side of multiple sand core positioning components in a 300-degree enclosed state. For example... Figure 5 and Figure 6 As shown, the sub-sand core 800 is placed inside the sand core positioning assembly 300.

[0031] In some embodiments, such as Figure 2 As shown, the sand core positioning block 310 includes a positioning boss 311 and a positioning post 312. The positioning post 312 is located on the positioning boss 311 and is used to insert the sub-sand core 800.

[0032] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the fixed plate 200 is positioned above the base plate 100, and the rotating disk 400 is positioned between the base plate 100 and the fixed plate 200. In this configuration, the fixed plate 200 can also serve as the upper limit structure for the rotating disk 400, simplifying the overall structure. Figure 1As shown, a support column 700 is provided between the fixed plate 200 and the base plate 100, and the support column 700 is located on the outside of the rotating disk 400. The fixed plate 200 and the base plate 100 are fixedly connected by the support column 700.

[0033] In some embodiments, the guide groove 210 extends through the fixed plate 200, and the sand core positioning assembly 300 passes through the guide groove 210 and is connected to the arc-shaped slide 410.

[0034] In some embodiments, such as Figure 3 and Figure 4 As shown, the driving element is a cylinder, and a transmission mechanism 600 is provided between the cylinder and the rotating disk 400. The cylinder can be a linear cylinder, and the transmission mechanism 600 converts the linear motion of the cylinder into the rotation of the rotating disk 400. In some embodiments, the cylinder can also be a rotary cylinder. In other embodiments, the driving element can also be a motor, and the transmission mechanism 600 is provided to drive the rotating disk 400 to rotate.

[0035] In other embodiments, the relative positions of the rotating disk 400 and the fixed plate 200 can also be adjusted, for example, the rotating disk 400 can be positioned above the fixed plate 200.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
