Description

Technical Field

[0001] The present application belongs to the technical field of sand core dip coating, and specifically relates to a transfer device for sand core dip coating. Background Art

[0002] The cylinder head sand core is a core body of a certain geometric shape made of sand or resin with certain requirements through a certain process, so as to form the filler of the casting cavity. Sand core dipping plays a vital role in the casting process. It has the advantages of improving the quality of castings, increasing the surface quality of castings, improving the corrosion resistance of castings, and enhancing the performance of sand cores.

[0003] In the related art, when dipping the sand core, it is necessary to first place the sand core on the workbench, then the robot grabs the sand core and places the sand core into the coating to form a protective layer on the surface of the sand core. However, after the sand core is placed on the workbench, the particles adhering to the sand core will fall onto the workbench, and then after the next sand core is placed on the workbench, the particles that fall onto the workbench may be located at the bottom of the sand core and may adhere to the sand core under the pressure of the sand core, which will affect the surface quality of the casting, so that the staff needs to clean the workbench in time, which results in a large workload for the staff and affects the dipping efficiency of the sand core.

[0045] Reference Figures 1 to 7 A sand core dipping and transferring device comprises a frame 1, a rotating frame 2 arranged on the frame 1, a positioning plate 3 arranged on the top of the rotating frame 2, and a driving member 4 arranged on the frame 1 for driving the rotating frame 2 to rotate. The positioning plate 3 has a sand falling opening 31 and a positioning jig 32 detachably connected thereto for positioning the sand core. A sand collecting tray 21 is arranged at the bottom of the rotating frame 2 corresponding to the sand falling opening 31.

[0046] When using the transfer device for dipping sand cores in the present application, the sand core is placed on the positioning jig 32 so that the positioning jig 32 positions and supports the sand core, and then the driving member 4 drives the rotating frame 2 so that the rotating frame 2 drives the sand core to rotate, and then the sand core rotates to the side where the robot is located, and then the robot grabs the sand core and places it in the coating to complete the dipping of the sand core. If the particles of the sand core fall off when the sand core is placed on the positioning plate 3, the particles will directly enter the sand collecting tray 21 through the sand falling port 31 to be collected in the sand collecting tray 21, thereby avoiding the need for the staff to clean the positioning plate 3 in time, thereby reducing the workload of the staff, and at the same time saving the time required for the staff to clean the positioning plate 3, thereby improving the dipping efficiency of the sand core.

[0047] The present application does not specifically limit the structure of the driving member 4. Preferably, the driving member 4 includes a motor, a reducer, and a turntable provided at the output end of the reducer, which are arranged on the frame 1. The input end of the reducer is connected to the output shaft of the motor, and the turntable is connected to the rotating frame 2, so that when the motor is working, the reducer drives the rotating frame 2 to move, so as to realize the rotation of the rotating frame 2. In other embodiments, the setting of the reducer can also be eliminated, so that the output shaft of the motor directly drives the rotating frame 2 to rotate.

[0048] In a preferred embodiment, the rotating frame 2 has a connecting area and a transfer area outside the connecting area, the positioning plate 3 is arranged in the transfer area, the driving member 4 is connected to the connecting area, and a guard plate 22 is arranged in the connecting area.

[0049] Since the transfer area is located outside the connection area and the driving member 4 is connected to the connection area, the space required to be occupied by the rotating frame 2 during the rotation process is reduced; a guard plate 22 is provided in the connection area so that the guard plate 22 shields the connection area to increase the aesthetics of the sand core dipping and transfer device, while increasing the safety of the sand core dipping and transfer device to prevent other components from falling into the connection area and affecting the rotation of the rotating frame 2, thereby ensuring the normal operation of the sand core dipping and transfer device.

[0050] The present application does not specifically limit the number of transfer zones. Preferably, the transfer zones are located on opposite sides of the connection zone. That is, the transfer device for dipping sand cores in the present application has two transfer zones, so that after one transfer zone rotates to the position of the robot, the other transfer zone rotates to the position where the sand core is placed, so as to shorten the waiting time of the robot, thereby further improving the efficiency of dipping sand cores and simplifying the control program of the drive member 4 to reduce the control cost of the transfer device for dipping sand cores. In other embodiments, multiple transfer zones may be provided and arranged along the circumference of the connection zone.

[0051] In a preferred embodiment, the frame 1 has a feeding end and a grabbing end arranged opposite to the feeding end, and the driving member 4 is located between the feeding end and the grabbing end.

[0052] Since the driving member 4 is located between the feeding end and the grabbing end, when the driving member 4 is working, the positioning plate 3 reciprocates between the feeding end and the grabbing end, so as to facilitate the placement of the sand core on the positioning plate 3 and the robot to grab the sand core on the positioning plate 3, so as to further improve the dipping efficiency of the sand core.

[0053] In a preferred embodiment, referring to Figure 1 , Figure 2 , Figure 3 and Figure 5 A tire placing plate 11 is provided at the feeding end, and a plurality of tire placing plates 11 are arranged at intervals along the vertical direction.

[0054] Since different sand cores require different positioning jigs 32, the jig placement plate 11 can be used to place idle positioning jigs 32 on the jig placement plate 11, thereby storing idle positioning jigs 32 to improve the utilization rate of the sand core dipping transfer device, and at the same time make it easier for staff to find suitable positioning jigs 32 to further improve the dipping efficiency of the sand core.

[0055] Further, see Figure 1 , Figure 2 , Figure 3 and Figure 6 A tire storage rack 12 is provided at the feeding end, and the tire storage rack 12 is arranged on one side of the tire placement plate 11.

[0056] Since the jig storage rack 12 and the jig placement plate 11 are provided, it is possible to classify and store idle positioning jigs 32 of different types to increase the flexibility of the transfer device for sand core dipping, and at the same time, it is further convenient for staff to find the corresponding type of positioning jig 32 to further improve the dipping efficiency of the sand core.

[0057] The present application does not specifically limit the positional relationship between the tire placement plate 11 and the tire storage rack 12 and the frame 1. Preferably, refer to Figure 1 , Figure 2 and Figure 3 An extension frame 13 is provided extending from the feeding end toward the outside of the frame 1 , and at least a portion of the tire placement plate 11 and the tire storage frame 12 are located in the extension frame 13 .

[0058] Since the extension frame 13 is extended toward the outside of the frame 1, and at least part of the jig placement plate 11 and the jig storage rack 12 are located in the extension frame 13, the internal space of the frame 1 occupied by the jig placement plate 11 and the jig storage rack 12 is reduced, so that the jig placement plate 11 and the jig storage rack 12 are avoided from the driving member 4, thereby achieving the effect of facilitating the assembly of the transfer device for sand core dipping.

[0059] In other implementation examples, the tire placement plate 11 and the tire storage rack 12 can be disposed inside the frame 1 .

[0060] Better, refer to Figure 6 The tire storage rack 12 is a box structure with an opening toward the outside of the frame 1 and has multiple accommodating cavities inside. The height between two adjacent tire placement plates 11 is greater than the space of the accommodating cavity, so that the tire storage rack 12 and the tire placement plate 11 are respectively used to place idle positioning tires 32 of different models.

[0061] Further, see Figure 1 , Figure 2and Figure 3 A tool box 131 with an upward opening is provided on the side of the extension frame 13 to store tools used when replacing the positioning jig 32, so as to facilitate the replacement of the positioning jig 32 and thereby improve the replacement efficiency of the positioning jig 32.

[0063] Since the extension piece 132 is provided with a placement hole, the columnar accessory of the transfer device for sand core dipping can be placed in the placement hole, so that the staff can take the accessory, thereby improving the dipping efficiency of the sand core.

[0064] The present application does not specifically limit the structure of the extension sheet 132. Preferably, refer to Figure 1 , Figure 2 and Figure 3 The extension piece 132 is L-shaped, one end of the extension piece 132 is fixedly connected to the tool box 131, and the other end of the extension piece 132 extends in a direction away from the tool box 131 to increase the connection stability between the extension piece 132 and the tool box 131. In other embodiments, the extension piece 132 can also be a sheet structure.

[0065] The present application does not specifically limit the connection method between the sand collecting tray 21 and the rotating frame 2. Preferably, refer to Figure 1 , Figure 2 , Figure 3 and Figure 7 A drawer tray 23 is provided at the bottom of the rotating frame 2, and an accommodating space with an opening toward the outside of the rotating frame 2 is formed between the drawer tray 23 and the rotating frame 2, and the sand collecting tray 21 extends into the accommodating space through the opening of the accommodating space.

[0066] Since the opening of the accommodating space faces the outside of the rotating frame 2 and the sand collecting tray 21 extends into the accommodating space through the opening of the accommodating space, the sand collecting tray 21 can be easily taken out to clean the particles in the sand collecting tray 21.

[0067] Further, see Figure 7 The sand collecting tray 21 has a pull rod 211 located outside the accommodating space, so that the staff can install the sand collecting tray 21 to the accommodating space and take the sand collecting tray 21 out of the accommodating space.

[0068] In other embodiments, the sand collecting tray 21 can also be fixedly connected to the rotating frame 2, and the bottom of the sand collecting tray 21 has a waste outlet, and a door body is movably connected to the waste outlet so that the door body can open or close the waste outlet to facilitate the cleaning of particles.
