Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, and in particular to a grinding device for grooves in castings. Background Technology

[0002] Castings are pressure-cast parts. They are made by using a pressure casting machine equipped with a casting mold. The heated metal such as copper, zinc, aluminum or aluminum alloy is poured into the feed port of the die casting machine and then pressure-cast to produce copper, zinc, aluminum or aluminum alloy parts with the shape and size limited by the mold. Such parts are usually called castings.

[0003] Many castings have numerous vertical surfaces on their surface, with a certain radius between two vertical surfaces to ensure the uniformity of stress distribution. However, existing grinding equipment lacks specialized grinding equipment for the radius of the castings, and there is also a lack of universal grinding equipment for the radius of different sizes, which affects the grinding efficiency of the castings.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0005] To address the aforementioned shortcomings, the present invention aims to provide a grinding device for grooves in castings. This device can be equipped with an adaptive grinding head structure, which ensures that during grinding, the grinding head can automatically adjust the state of its edge according to the different grinding positions. This allows it to adapt to grinding rounded corners of different sizes, thereby optimizing the grinding efficiency of castings.

[0009] A control sleeve is disposed on the outside of the grinding head. A deformable grinding layer is provided between the control sleeve and the grinding head. When the grinding head moves to the point where the control sleeve is in contact with the side wall, the grinding layer is forced to adhere to the rounded corner of the workpiece and grinds the rounded corner.

[0010] In one embodiment, the bottom of the grinding head is provided with a grinding plate, the control sleeve is sleeved on the outside of the grinding head, the outer ring of the grinding layer is fixed to the outside of the bottom of the control sleeve, and the inner ring is fixed to the outer wall of the grinding head. When grinding the rounded corner, the control sleeve abuts against the top of the rounded corner, and the grinding layer adheres tightly to the rounded corner under the action of the rotation of the grinding head.

[0011] In one embodiment, the top of the grinding head is provided with a rotating shaft, the rotating shaft is fixedly installed on the output shaft of the drive component, a drive plate is slidably provided on the rotating shaft, and an elastic layer is provided between the drive plate and the top of the control sleeve.

[0017] In one embodiment, a filling space is provided between the grinding head and the drive plate, and the filling space is filled with a non-Newtonian fluid. The top of the grinding plate is provided with a plurality of top baffles, and the bottom of the drive plate is provided with a plurality of bottom baffles. The rotation of the grinding plate drives the drive plate to rotate synchronously, and under centrifugal force, the grinding layer is pressed tightly against the rounded corner.

[0018] In one embodiment, the control sleeve has an external mounting ring groove, and a grinding ring is installed inside the mounting ring groove.

[0036] See Figure 1 , Figure 2 , Figure 3 and Figure 4This invention provides a grinding device for grooves in castings. The device includes a drive unit, which can be a rotary motor, that drives a grinding mechanism 4 to rotate, thereby effectively grinding the grooves 2 of the casting 1. The grinding mechanism 4 is located at the output end of the drive unit. By grinding the grooves 2 of the casting 1 with the grinding mechanism 4, the grinding effect of the grooves 2 is ensured. The grinding mechanism 4 includes:

[0037] A grinding head 41 is used to grind the surface of the casting 1. The grinding head 41 is installed at the output end of the drive component. The drive component drives the grinding head 41 to rotate synchronously, thereby effectively achieving the grinding effect of the grinding head 41 on the groove 2 of the casting 1.

[0038] A control sleeve 46 is provided on the outside of the grinding head 41. A deformable grinding layer 45 is provided between the control sleeve 46 and the grinding head 41. By providing a deformable grinding layer 45, it is ensured that when the rounded corner 3 needs to be ground, the grinding layer 45 can be tightly attached to the outer wall of the rounded corner 3, so that the rounded corner 3 can be effectively ground. When the grinding head 41 moves to the point where the control sleeve 46 is in contact with the side wall, the grinding layer 45 is forced to adhere to the rounded corner 3 and grinds the rounded corner 3, so that the rounded corner 3 can be effectively and fully ground.

[0039] In one embodiment, in order to achieve the grinding effect on the outer wall of the rounded corner 3, a grinding plate 413 is provided at the bottom of the grinding head 41. By setting the grinding plate 413, the groove 2 of the casting 1 is ground to ensure the grinding effect. The control sleeve 46 is sleeved on the outside of the grinding head 41. The outer ring of the grinding layer 45 is fixed to the outside of the bottom of the control sleeve 46, and the inner ring is fixed to the outer wall of the grinding head 41. When grinding the rounded corner 3, the control sleeve 46 abuts against the top of the rounded corner 3. The grinding layer 45 is tightly attached to the rounded corner 3 under the action of the rotation of the grinding head 41, so as to effectively grind the position of the rounded corner 3. It is ensured that the grinding layer 45 can be displaced relative to the rounded corner 3 while the grinding head 41 is rotating, so as to effectively grind the position of the rounded corner 3.

[0040] In one exemplary implementation, combined with Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9To enable the grinding head 41 to adapt to different sizes of fillets 3, a rotating shaft is provided on the top of the grinding head 41. The rotating shaft is fixedly mounted on the output shaft of the drive component, ensuring that the rotating shaft can be driven to rotate synchronously by the drive component, thereby grinding the predetermined position. A drive plate 43 is slidably mounted on the rotating shaft, and an elastic layer 48 is provided between the drive plate 43 and the top of the control sleeve 46. This ensures that the rotational force can be transmitted to the control sleeve 46 through the elastic layer 48 by the rotation of the drive plate 43, thereby effectively driving the control sleeve 46 to rotate synchronously without affecting the position of the control sleeve 46, ensuring that it can be used for grinding. For grinding of different sized fillet 3, the elastic layer 48 is a rubber layer, ensuring that when the control sleeve 46 is moved under force, the rubber layer can drive the control sleeve 46 to move. And when the control sleeve 46 is in any position, the rotation of the rotating shaft can synchronously drive the control sleeve 46 to rotate. In order to ensure that the rubber layer can transmit the power to the control sleeve 46, one end of the rubber layer can be fixed to the drive plate 43 and the other end can be fixed to the top of the control sleeve 46. The drive plate 43 rotates synchronously with the rotating shaft and drives the control sleeve 46 to rotate synchronously. While ensuring rotation, the position of the control sleeve 46 can be moved.

[0041] In one embodiment, in order to provide space for the control sleeve 46 to move, a movable space is provided between the outer side of the drive plate 43 and the inner side of the control sleeve 46. The rubber layer is disposed inside the movable space. The control sleeve 46 moves relative to the position of the drive plate 43 when subjected to force, so that the control sleeve 46 can move under force to adapt to different sizes of rounded corners 3, and ensure that the polishing layer 45 can fit tightly against the outer wall of rounded corners 3 of different sizes.

[0042] Specifically, to ensure the normal sliding and installation effect of the drive plate 43, a groove 411 is provided on the rotating shaft, and a sliding hole and a sliding protrusion 432 that is slidably connected to the inside of the groove 411 are provided on the drive plate 43. This ensures that the drive plate 43 can slide up and down on the rotating shaft, and the rotation of the rotating shaft can drive the drive plate 43 to rotate normally. A tension spring 42 is provided between the drive plate 43 and the grinding head 41 to move the drive plate 43 closer to the grinding head 41. The grinding layer 45 is made of elastic material, and a grinding surface is provided on the outer side of the grinding layer 45. The grinding surface is in close contact with the rounded corner 3 and grinds the rounded corner 3. Under the action of centrifugal force, the grinding layer 45 deforms to be in close contact with the rounded corner 3, ensuring the grinding effect of the rounded corner 3.

[0043] In one embodiment, in order to ensure the grinding force between the grinding layer 45 and the rounded corner 3, a plurality of uniformly arranged gravity blocks 47 are attached to the inner wall of the grinding layer 45. During the rotation of the grinding head 41, the gravity blocks 47 press the grinding layer 45 outward so that the grinding surface is in close contact with the inner wall of the rounded corner 3. This ensures that the gravity blocks 47 can move outward under the action of centrifugal force, thereby ensuring the centrifugal force of the grinding layer 45 and further ensuring the adhesion between the grinding layer 45 and the rounded corner 3. During relative rotation, the grinding surface can effectively grind the rounded corner 3.

[0044] In this embodiment, during use, when the grinding head 41 grinds the inner surface of the groove 2, the drive plate 43 is pulled to its lowest point under the action of the tension spring 42. Simultaneously, the control sleeve 46 moves downwards under the pulling force of the drive plate 43. To ensure the initial position of the control sleeve 46, a limiting part can be provided on the rotating shaft. The limiting part restricts the position of the drive plate 43, further ensuring the position of the control sleeve 46. At this time, the grinding layer 45 corresponds to the grinding surface, grinding the inner surface of the groove 2. When the grinding head 41 moves to the edge of the groove 2, the rounded corner 3 abuts against the outside of the control sleeve 46. Under the action of the abutment force of the rounded corner 3, it slides upward and pulls the polishing layer 45 to bend. Under the action of the rapid rotation of the polishing head 41, the control sleeve 46 abuts against the side wall of the groove 2 and is located at the top of the rounded corner 3. At the same time, the bottom polishing head 41 is located at the bottom edge of the rounded corner 3. Simultaneously, the polishing layer 45 rotates, and the gravity block 47 is subjected to centrifugal force to press the polishing surface of the polishing layer 45 onto the rounded corner 3, thereby polishing the rounded corner 3. When the position of the control sleeve 46 is squeezed, the control sleeve 46 can move laterally. When the axis of the control sleeve 46 does not coincide with the axis of the rotating shaft, the control sleeve 46 can still be driven to rotate synchronously through the action of the elastic layer 48.

[0045] In another embodiment, combined with Figure 8 and Figure 9 To achieve the desired polishing effect and the synchronous rotation of the grinding head 41, driving the drive plate 43 and control sleeve 46, the main difference from the previous embodiment is that a filling space is provided between the grinding head 41 and the drive plate 43. The filling space is filled with a non-Newtonian fluid. The top of the grinding plate 413 is provided with several top baffles 412, and the bottom of the drive plate 43 is provided with several bottom baffles 431. Alternatively, an inner baffle can be provided on the inner wall of the control sleeve 46. This ensures that while the grinding head 41 rotates, it can drive the control sleeve 46 and drive plate 43 to rotate synchronously under the shear resistance effect of the non-Newtonian fluid, thus achieving the polishing effect. At the same time, the rotation of the grinding plate 413 drives the drive plate 43 to rotate synchronously, and under centrifugal force, it presses the polishing layer 45 tightly against the rounded corner 3.

[0046] In this embodiment, when the control sleeve 46 is pressed upward against the top edge of the rounded corner 3 during use, the force of the polishing layer 45 pressing against the rounded corner 3 is provided by the centrifugal force of the non-Newtonian fluid. This method ensures that the pressing force on the polishing layer 45 is uniform, thereby guaranteeing the polishing effect of the rounded corner 3.

[0047] In another embodiment, in order to ensure that the control sleeve 46 can polish the sidewall of the groove 2, the control sleeve 46 is provided with an installation ring groove 461 on the outside. A polishing ring 44 is installed inside the installation ring groove 461. When the control sleeve 46 rotates synchronously, the sidewall of the groove 2 can be polished synchronously to ensure the polishing effect. Alternatively, a rotating bearing can be directly set on the outside of the control sleeve 46 to ensure that the outside of the rotating bearing does not rotate synchronously with the control sleeve 46, so that the sidewall of the groove 2 will not be polished.

[0048] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
