[0044] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0046] It should be emphasized and explained that the various connection methods involved in this utility model can be arbitrary unless otherwise specified. For example, fixed connection can be achieved by bolts and nuts for detachable fixing, welding or integral molding, etc. Sliding connection can be achieved by groove-like or guide rail-like structures of various shapes, and rotating connection can be achieved by hinges, shafts, etc. Any existing method that can achieve the corresponding connection relationship is acceptable.

[0047] The following is combined Figures 1-10 The sand-vibrating device for irregularly shaped castings involved in this utility model will be further explained.

[0048] A sand-vibrating device for irregularly shaped castings 6 includes a frame 1, a fixing component 2, a support column 3, a housing 4, and a connecting pipe 5. The fixing component 2 is mounted on the frame 1 and used to fix the irregularly shaped casting 6. The support column 3 is mounted on the frame 1. The housing 4 is fixedly connected to the end of the support column 3 away from the frame 1. A through hole 41 is provided on the bottom of the housing 4, through which steel balls 7 are received. One end of the connecting pipe 5 communicates with the space inside the housing 4 through the through hole 41, and the other end communicates with the irregularly shaped casting 6, so that the steel balls 7 can be guided into the irregularly shaped casting 6 to impact and vibrate it.

[0049] In this embodiment, the sand-vibrating device can guide steel balls 7 one by one into the inner cavity of the irregular casting 6 through the connecting pipe 5. This can impact and vibrate the irregular casting 6, thereby helping to shake out the sand particles in the inner cavity of the irregular casting 6, solving the technical problem that the inner cavity of the existing irregular casting 6 is difficult to clean.

[0050] Specifically, during use, the user can directly place the steel balls 7 into the through holes 41 on the box body 4, or directly pour a large number of steel balls 7 into the box body 4, and then roll the steel balls 7 so that the steel balls 7 enter the through holes 41 in sequence. It can be understood that the box body 4 is open-ended.

[0051] In addition, the fixing component 2 can be a fixing seat-like structural member that matches the shape of the special-shaped casting 6 for support and fixation, or can also be fixed by clamping, tying, etc.

[0052] In addition, the sand shaking device of the present utility model is aimed at special-shaped castings 6 with inner cavities, and has channels inside, that is, the connecting pipe 5 is the connecting channel entrance, and the steel balls 7 can flow out from the channel outlet.

[0053] In an embodiment of a sand shaking device for special-shaped castings 6, the number of the fixing components 2, the through holes 41, and the connecting pipes 5 is multiple. One end of each connecting pipe 5 corresponds to each through hole 41 respectively, and the other end is used to communicate with the special-shaped castings 6 on each fixing component 2.

[0054] In this embodiment, by providing multiple fixing components 2, multiple through holes 41, and multiple connecting pipes 5, sand shaking can be performed on multiple special-shaped castings 6 in this way.

[0055] Preferably, the distribution of the fixing components 2 can be arranged in a circumferential array.

[0056] In an embodiment of a sand shaking device for special-shaped castings 6, the connecting pipe 5 includes a first section and a second section that are fixedly connected and communicate with each other. The end of the first section far from the second section communicates with the through hole 41, and the second section is a telescopic pipe. The end of the second section far from the first section is used to communicate with the special-shaped casting 6.

[0057] In this embodiment, by setting the second section as a telescopic pipe, it is convenient to dock with special-shaped castings 6 of different sizes and shapes, improving the versatility of the overall sand shaking device.

[0058] Further preferably, the shape of the connecting pipe 5 can be straight cylindrical, Z-shaped, arc-shaped, L-shaped, etc., and can also be bent in the middle in the attached drawing to form a shape similar to a "person" character.

[0059] In an embodiment of a sand shaking device for special-shaped castings 6, the frame body 1 includes a support disk 11 and multiple support rods 12. The outer circle of the support disk 11 is fixedly connected to the middle of the support rods 12. Each support rod 12 is evenly distributed along the circumferential direction of the support disk 11 and is arranged parallel to the axial direction of the support disk 11.

[0060] In this embodiment, the frame body 1 includes a support disk 11 and support rods 12. By using the support rods 12 to lift the support disk 11, the support disk 11 can be elevated, thus leaving a bottom space for conveniently placing other components.

[0061] In one embodiment of a sand-vibrating device for irregularly shaped castings 6, the sand-vibrating device further includes a motor 81, an internal gear ring 82, a sun gear 83, and planetary gears 84 in the same number as the fixed assembly 2. The internal gear ring 82 is fixedly mounted on a support plate 11. The output shaft of the motor 81 passes through the support plate 11 and is fixedly connected to and coaxially arranged with the sun gear 83. The sun gear 83 is coaxially arranged with the internal gear ring 82. Each planetary gear 84 is evenly distributed between the sun gear 83 and the internal gear ring 82 and meshes with the sun gear 83 and the internal gear ring 82. A protrusion 841 is provided at the axial position of the planetary gear 84 so as to connect the planetary gear 84 to the fixed assembly 2. The fixed assembly 2 is connected to the protrusion 841 through a bottom embedded bearing. The support column 3 includes a column body 31 and a rotating disk 32. The rotating disk 32 is fixedly connected to the column body 31 and to the sun gear 83. The end of the column body 31 away from the rotating disk 32 is fixedly connected to the box body 4. The gap between the rotating disk 32 and the internal gear ring 82 is smaller than the diameter of the steel ball 7.

[0062] In conjunction with the previous embodiments, the motor 81 in this embodiment can be placed in the bottom space of the frame 1. The internal gear ring 82, the sun gear 83, and the planet gears 84 form a planetary gear transmission mechanism. Through the motor 81 and the planetary gear transmission mechanism, the fixed component 2 can be driven to rotate the irregularly shaped casting 6 on it around the plane. In this way, during the rotation of the box 4, the steel ball 7 inside the box 4 can move, so that the steel ball 7 can automatically enter the connecting pipe 5. In addition, since a planetary gear transmission mechanism is used, in order to prevent the steel ball 7 from entering between the sun gear 83 and the planet gears 84, the gap between the rotating disk 32 and the internal gear ring 82 is set to be smaller than the diameter of the steel ball 7, which can prevent the steel ball 7 from entering between the sun gear 83 and the planet gears 84.

[0063] It is understandable that the sand particles in the irregular casting 6 are in a dead corner and are in small quantities, requiring vibration to shake them out. Therefore, the amount of sand particles entering between the sun gear 83 and the planet gear 84 is also small and will not affect the movement. More preferably, the gap between the rotating disk 32 and the internal gear ring 82 is set to be smaller than the diameter of the steel ball 7, and the gap between the two is zero, that is, the planetary gear transmission mechanism is completely closed. The protrusion 841 on the planet gear 84 extends through the rotating disk 32 and is fixedly connected to the fixed component 2. After the protrusion 841 passes through, the gap is sealed. This can completely prevent the sand particles flowing out of the irregular casting 6 from entering between the sun gear 83 and the planet gear 84.

[0064] In addition, by providing a bearing on the fixed component 2 to connect with the protrusion 841, it is possible to prevent the planetary gear 84 from rotating and causing the fixed component 2 to rotate, so that the fixed component 2 can only rotate around the sun gear 83.

[0065] In one embodiment of a sand-vibrating device for a non-shaped casting, the internal gear ring 82 includes, in sequence along the axial direction, a connected ring 821, a connecting ring 822, and a disc 823. The diameter of the connecting ring 822 is smaller than the diameter of the ring 821. The inner wall of the connecting ring 822 is provided with teeth. A hole is opened at the axial position of the disc 823 for the output shaft of the motor 81 to pass through.

[0066] In this embodiment, by configuring the internal gear ring 82 into a structure consisting of a circular ring 821, a connecting ring 822, and a disc 823, the teeth on the internal gear ring 82 can be located on the inner wall of the connecting ring 822 in the middle. This can effectively enclose part of the planetary gear 84, thus achieving a better enclosing effect. In conjunction with the previous embodiment, the rotating disc 32 of the support column 3 abuts against the inner wall of the circular ring 821 and is sealed by a sealing ring.

[0067] In one embodiment of a sand-vibrating device for irregularly shaped castings, the column 31 is a hollow structure.

[0068] In this embodiment, by making the column 31 hollow, the mass of the column 31 can be reduced.

[0069] In one embodiment of a sand-vibrating device for a non-shaped casting 6, the sand-vibrating device further includes multiple impact modules. Each impact module is arranged circumferentially around the support plate 11 and connected to each support rod 12. Each impact module includes an elastic element 91 and an impact ball 92. One end of the elastic element 91 is fixedly connected to the support rod 12, and the other end is fixedly connected to the impact ball 92. The impact ball 92 is located on the rotation path of the non-shaped casting 6.

[0070] In this embodiment, by setting the elastic element 91 and the impact ball 92, the irregular casting 6 can collide with the impact ball 92 when it rotates. After being impacted, the impact ball 92 will deviate and then rebound under the action of the elastic element 91. The rebound produces an erratic swing direction, thus producing irregular knocking on the irregular casting 6, thereby further strengthening the vibration of the irregular casting 6 and further improving the effect of removing sand particles from the cavity of the irregular casting 6.

[0071] Specifically, the number of impact modules can be the same as the number of fixing components 2, or half the number of support rods 12.

[0072] In one embodiment of a sand-vibrating device for a non-shaped casting 6, the fixing component 2 includes a mounting base 21 and a clamping module. The mounting base 21 is fixedly connected to the protrusion 841, and the clamping module is mounted on the mounting base 21 and used to clamp the non-shaped casting 6. The clamping module includes two jaws 22 and a lead screw 23. A groove 211 is provided on the mounting base 21, and parts of the two jaws 22 extend into the groove 211. The lead screw 23 passes through the two jaws 22 along the extension direction of the groove 211 and is threadedly connected to the two jaws 22. The threads of the lead screw 23 and the two jaws 22 are in opposite directions.

[0073] In this embodiment, the fixing component 2 uses a clamping method to fix the irregular casting 6. By using a lead screw 23 and two jaws 22, it is convenient for the staff to operate and clamp the irregular casting 6 by themselves. When clamping, the outlet of the irregular casting 6 is placed outside the groove 211 to prevent sand particles from entering the groove 211.

[0074] In conjunction with the previous embodiment, the bearing is embedded in the mounting base 21.

[0075] In one embodiment of a sand-vibrating device for irregularly shaped castings, the fixing component 2 is a pneumatic gripper 22.

[0076] Unlike the previous embodiments, the fixing component 2 can directly adopt a pneumatic gripper 22, which can reduce development costs and facilitate operation by staff. The clamping of the irregular casting 6 can be completed with a simple switch, while the previous embodiments require the screw 23 to be rotated manually.

[0077] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0078] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
