Description

Technical Field

[0001] This utility model relates to the technical field of grinding devices, specifically a grinding device for ductile iron castings. Background Technology

[0002] Ductile iron is a high-performance cast iron obtained by spheroidizing and inoculating white cast iron. The precipitated graphite is spherical, hence the name ductile iron. The plasticity and toughness of ductile iron are significantly improved compared to ordinary cast iron, so it can "replace steel with iron" in some areas.

[0003] Currently, ductile iron parts require surface grinding after forming to remove burrs. However, most grinding methods currently involve external clamping of the ductile iron parts, making it difficult to grind the clamped areas. This necessitates adjusting the position of the ductile iron parts, but conventional support platforms are not convenient for height adjustment. Consequently, the rotation of the ductile iron parts is easily affected by the clamping structure. Therefore, we propose a grinding device for ductile iron parts. Utility Model Content

[0004] The purpose of this invention is to provide a grinding device for ductile iron castings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a grinding device for ductile iron parts, comprising a first support member, a second support member rotatably connected to the first support member, the second support member being rotatable by a driving component, a third support member slidable up and down connected to the second support member, a lifting component for driving the third support member to slide up and down in the inner cavity of the second support member, a fourth support member mounted on the first support member, and a clamping component mounted on the fourth support member.

[0006] Preferably, the lifting assembly includes a cam, a first motor, and a first limiting rod. The inner cavity of the second support member is fitted with the rotatable cam. One end of the camshaft is connected to the output end of the first motor. Two sets of the first limiting rods are symmetrically installed at the bottom end of the third support member. The first limiting rods pass through the second support member and are slidably connected to it.

[0007] Preferably, the drive assembly includes a first gear, a second gear, and a second motor. The rotating rod of the second support penetrates the first support and connects to the first gear. The first gear meshes with the second gear, and the second gear is connected to the output end of the second motor mounted on the upper surface of the first support.

[0008] Preferably, the clamping assembly includes a first electric push rod and a clamping block. A set of the first electric push rods is installed on each side of the fourth support member. The two sets of the first electric push rods are arranged in a mirror image. The output end of each set of the first electric push rods is connected to a set of clamping blocks. The two sets of clamping blocks are arranged in a mirror image.

[0009] Preferably, one side of the fourth support member is connected to a limiting seat via an adjustment component, and the limiting seat is connected to a grinding component via a moving component.

[0010] Preferably, the adjustment assembly includes a second electric push rod and a second limiting rod. The second electric push rod is installed in the inner cavity of the fourth support member. The output end of the second electric push rod extends toward one side of the fourth support member and is connected to the limiting seat. Two sets of the second limiting rods are symmetrically installed on one side of the limiting seat facing the fourth support member. The two sets of the second limiting rods penetrate the fourth support member and are slidably connected to it.

[0011] Preferably, the moving component includes a screw, a third motor, and a third limiting rod. The screw is rotatable and installed in the inner cavity of the limiting seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model utilizes a lifting component to allow the third support to rise and fall along the second support. By adjusting the height of the third support, its upper surface can extend beyond the clamping component. Thus, when the second and third supports are rotated by the driving component, the ductile iron part placed on the third support will not be affected by the clamping component, thereby not affecting the orientation adjustment of the ductile iron part, facilitating subsequent grinding and improving grinding efficiency.

[0014] 2. This utility model starts the first motor, which drives the cam to rotate, causing it to lift the third support member. At the same time, the first limiting rod connected to it slides along the second support member, which can improve the stability of the lifting and lowering of the third support member. By starting the second motor, the second gear is driven to rotate, causing the first gear meshing with it to rotate, which in turn drives the second support member to rotate, thus causing the third support member connected to it to rotate, realizing the rotation of the ductile iron part. By extending the first electric push rod, the clamping block can be moved. The two sets of clamping blocks can clamp and limit the ductile iron part, ensuring stability during the grinding process.

[0015] 3. This utility model, through the extension of the second electric push rod, can push the limiting seat to move the grinding part away from the fourth support, so that the ductile iron part will not be affected when rotating. When the limiting seat moves, it will drive the second limiting rod to move, which can improve its stability during movement. By starting the third motor, the screw connected to it will rotate, and the third limiting rod connected to it will slide along the inner cavity of the limiting seat, which can drive the grinding part to move, and the outer wall of the ductile iron part can be ground.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please refer to Figure 1-3 As shown, this utility model provides a grinding device for ductile iron parts, including a first support member 1, a second support member 2 rotatably connected to the first support member 1, the second support member 2 being able to rotate via a drive assembly, a third support member 3 slidably connected to the second support member 2, a lifting assembly for driving the third support member 3 to slide up and down in the inner cavity of the second support member 2, a fourth support member 4 installed on the first support member 1, and a clamping assembly installed on the fourth support member 4.

[0023] In this embodiment, the lifting component allows the third support 3 to be raised and lowered along the second support 2. Adjusting the height of the third support 3 allows its upper surface to extend beyond the clamping component. Thus, when the second support 2 and the third support 3 are rotated by the driving component, the ductile iron part placed on the third support 3 will not be affected by the clamping component, thereby not affecting the orientation adjustment of the ductile iron part, facilitating subsequent grinding and improving grinding efficiency.

[0024] Please refer to Figure 1-3 As shown, the lifting assembly includes a cam 5, a first motor 6, and a first limiting rod 7. A rotatable cam 5 is installed in the inner cavity of the second support member 2. One end of the cam 5 shaft is connected to the output end of the first motor 6. Two sets of first limiting rods 7 are symmetrically installed at the bottom end of the third support member 3. The first limiting rods 7 pass through the second support member 2 and are slidably connected to it. The driving assembly includes a first gear 8, a second gear 9, and a second motor 10. The rotating rod of the second support member 2 passes through the first support member 1 and is connected to the first gear 8. The first gear 8 meshes with the second gear 9. The second gear 9 is connected to the output end of the second motor 10 installed on the upper surface of the first support member 1. The clamping assembly includes a first electric push rod 11 and a clamping block 12. A set of first electric push rods 11 is installed on each side of the fourth support member 4. The two sets of first electric push rods 11 are arranged in a mirror image. The output end of each set of first electric push rods 11 is connected to a clamping block 12. The two sets of clamping blocks 12 are arranged in a mirror image.

[0025] In this embodiment, by starting the first motor 6, the cam 5 is driven to rotate, which lifts the third support 3. At the same time, the first limiting rod 7 connected to it slides along the second support 2, which can improve the stability of the lifting and lowering of the third support 3. By starting the second motor 10, the second gear 9 is driven to rotate, which in turn drives the first gear 8 meshing with it to rotate, thereby driving the second support 2 to rotate, which in turn drives the third support 3 connected to it to rotate, realizing the rotation of the ductile iron part. By extending the first electric push rod 11, the clamping block 12 can be pushed to move. The two sets of clamping blocks 12 can clamp and limit the ductile iron part, ensuring the stability during the grinding process.

[0026] Please refer to Figure 1-3As shown, one side of the fourth support member 4 is connected to a limiting seat 13 via an adjustment assembly. The limiting seat 13 is connected to a grinding member 14 via a moving assembly. The adjustment assembly includes a second electric push rod 15 and a second limiting rod 16. The second electric push rod 15 is installed in the inner cavity of the fourth support member 4. The output end of the second electric push rod 15 extends toward one side of the fourth support member 4 and is connected to the limiting seat 13. Two sets of second limiting rods 16 are symmetrically installed on one side of the limiting seat 13 facing the fourth support member 4. The two sets of second limiting rods 16 penetrate the fourth support member 4 and are slidably connected to it. The moving assembly includes a screw 17, a third motor 18, and a third limiting rod 19. The rotatable screw 17 is installed in the inner cavity of the limiting seat 13. One end of the screw 17 is connected to the output end of the third motor 18. The screw 17 passes through the third limiting rod 19, and the two are threadedly connected. The third limiting rod 19 can slide along the inner cavity of the limiting seat 13. The bottom end of the third limiting rod 19 is connected to the grinding member 14.

[0027] In this embodiment, by extending the second electric push rod 15, the limiting seat 13 can be pushed to move the grinding part 14 away from the fourth support member 4, so that the ductile iron part will not be affected when rotating. When the limiting seat 13 moves, it will drive the second limiting rod 16 to move, which can improve its stability when moving. By starting the third motor 18, the screw 17 connected to it will rotate, and the third limiting rod 16 connected to it will slide along the inner cavity of the limiting seat 13, which can drive the grinding part 14 to move, and the outer wall of the ductile iron part can be ground.

[0028] Working principle: First, by starting the first motor 6, the cam 5 rotates, lifting the third support 3. Simultaneously, the first limiting rod 7 connected to it slides along the second support 2, improving the stability of the lifting of the third support 3. By starting the second motor 10, the second gear 9 rotates, causing the first gear 8 meshing with it to rotate, which in turn rotates the second support 2, allowing the third support 3 connected to it to rotate, thus realizing the rotation of the ductile iron casting. By extending the first electric push rod 11, the clamping block 12 can be moved. Using the two sets of clamping blocks 12, the ductile iron casting can be rotated. The iron part is clamped and limited to ensure stability during the grinding process. By extending the second electric push rod 15, the limit seat 13 can be pushed to move the grinding part 14 away from the fourth support 4, so that the ductile iron part will not be affected when rotating. When the limit seat 13 moves, it will drive the second limit rod 16 to move, which can improve its stability during movement. By starting the third motor 18, the screw 17 connected to it will rotate, and the third limit rod 16 connected to it will slide along the inner cavity of the limit seat 13, which can drive the grinding part 14 to move, so that the outer wall of the ductile iron part can be ground.
