Description

Technical Field

[0001] This utility model relates to the field of cylindrical casting production technology, and in particular to a cylindrical casting gate trimming device. Background Technology

[0002] Castings are metal shaped objects obtained by various casting methods. They are objects with a certain shape, size and properties obtained by pouring, injecting, sucking or other casting methods into a pre-prepared mold after smelting liquid metal, cooling and then grinding.

[0003] For example, after a cylindrical casting is formed, there will be burrs at the gate position. Therefore, the gate position of the casting needs to be repaired. The conventional repair method is usually for workers to use a hand-held grinder to grind the gate position of the casting. Prolonged operation can easily lead to operational errors by workers, causing them to injure themselves, which is not conducive to production and processing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a cylindrical casting gate trimming device to solve the problems mentioned in the background art.

[0005] A cylindrical casting gate trimming device includes a base and a grinding mechanism and a limiting component mounted on the base. The grinding mechanism includes a slide rod, a movable frame, a fixed rod, a spring, a screw, a connecting plate, a motor, and a grinding roller. Two slide rods are mounted opposite each other on the base. The movable frame is slidably mounted on the slide rods. The fixed rod is fixed to the bottom surface of the connecting plate and inserted downward into the movable frame. The spring is sleeved on the outside of the fixed rod and located between the connecting plate and the movable frame. The screw is fixedly mounted on the movable frame and passes upward through the connecting plate. The screw is also provided with a nut to limit the upward movement of the connecting plate. The motor is mounted below the connecting plate, and the grinding roller is fixedly connected to the output end of the motor. The limiting assembly includes a limiting plate, a limiting head, and bolts. Multiple limiting plates are provided, and the limiting plates can be threadedly connected to the corresponding threaded holes on the base through the bolts to limit the movement of the limiting plates. The limiting head is installed on the side of the limiting plate and is used to limit the cylindrical casting by cooperating with an adjacent limiting plate.

[0006] By adopting the above technical solution, it is possible to grind the gate position of the cylindrical casting.

[0007] The bottom of the mobile frame is also equipped with multiple rollers that slide along the upper surface of the base.

[0008] The above technical solution is used to assist in the movement of the mobile frame.

[0009] A handheld part is also fixedly installed on the connecting plate.

[0010] By adopting the above technical solution, the grinding mechanism can be manually pushed to grind the gate position of the cylindrical casting.

[0011] The limiting head includes a fixing block and a rubber pad. The fixing block is generally arranged in a trapezoidal structure, and the rubber pad is adhered to the inclined surfaces on both sides of the fixing block.

[0012] By adopting the above technical solution, the cylindrical casting is limited, reducing hard contact.

[0013] The base has two rows of threaded holes evenly arranged, and the limiting head is located between the two rows of threaded holes and below the grinding roller.

[0014] By adopting the above technical solution, the distance between two adjacent limiting plates is adjusted according to the size of the cylindrical casting.

[0015] The beneficial effects of this utility model's cylindrical casting gate trimming device are: The spacing between the limiting plates can be adjusted in advance according to the size of the cylindrical casting to limit the cylindrical casting. Then, the height of the connecting plate can be adjusted according to the height of the cylindrical casting so that the grinding roller can contact the top of the cylindrical casting to facilitate grinding at the gate position of the cylindrical casting. After adjusting the height of the connecting plate, the bolt on the screw can be rotated to restrict the upward movement of the connecting plate. The hand-held part can be used to push the grinding mechanism to move as a whole. At this time, the moving frame can move along the base surface via the roller and move horizontally along the slide rod at the same time. The grinding roller can be used to grind the cylindrical casting to facilitate grinding at the gate position of the cylindrical casting. Attached Figure Description

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0019] This utility model provides a trimming device, such as a trimming device for the gate of a cylindrical casting.

[0020] Includes a base 1 and a grinding mechanism and a limiting component 12 mounted on the base 1. Reference Figure 1 Detailed description of the grinding mechanism: The grinding mechanism includes a slide rod 2, a movable frame 3, a fixed rod 5, a spring 6, a screw 7, a connecting plate 8, a motor 9, and a grinding roller 10. The slide rod 2 consists of two opposing parts mounted on the base 1. The movable frame 3 is slidably mounted on the slide rod 2. The fixed rod 5 is fixed to the bottom surface of the connecting plate 8 and inserted downward into the movable frame 3. The spring 6 is sleeved on the outside of the fixed rod 5 and located between the connecting plate 8 and the movable frame 3. The screw 7 is fixedly mounted on the movable frame 3 and extends upward through the connecting plate 8. The screw 7 is also provided with a nut to restrict the upward movement of the connecting plate 8. The motor 9 is mounted below the connecting plate 8. The grinding roller 10 is fixedly connected to the output end of the motor 9. Two fixing rods 5 are set at the bottom of both ends of the connecting plate 8 to increase the stability of the connecting plate 8. Two sets of springs 6 are set, with two springs in each set, which can support the connecting plate 8. Then, pressing the connecting plate 8 will cause it to move slightly downward, which will allow the position of the cylindrical casting gate to be polished.

[0021] The bottom of the movable frame 3 is also provided with multiple rollers 4 that slide along the upper surface of the base 1; when the grinding mechanism is pushed to move, the movable frame 3 moves along the slide bar 2, and the rollers 4 at the bottom of the movable frame 3 can assist the rollers 4 in moving.

[0022] A handheld part 11 is also fixedly installed on the connecting plate 8; the handheld part 11 can be used to push the grinding mechanism to move, so as to facilitate operation and grind the position of the gate of the cylindrical casting.

[0023] Reference Figure 2 Detailed description of the limiting component 12: The limiting component 12 includes a limiting plate 1201, a limiting head 1202, and bolts 1203. Multiple limiting plates 1201 are provided and can be threadedly connected to corresponding threaded holes 101 on the base 1 via bolts 1203 to limit the movement of the limiting plates 1201. The limiting head 1202 is installed on the side of the limiting plate 1201 and is used to limit the cylindrical casting by engaging with an adjacent limiting plate 1201. The limiting heads 1202 on opposite sides of two adjacent limiting plates 1201 can restrict the cylindrical casting. A cylindrical casting can be limited by being surrounded by four closely spaced limiting heads 1202. (Refer to...) Figure 2 In other words, two cylindrical castings can be placed between two adjacent limiting plates 1201.

[0024] In order to reduce hard contact with the cylindrical casting, the limiting head 1202 includes a fixing block and a rubber pad. The fixing block is generally arranged in a trapezoidal structure, and the rubber pad is bonded to the inclined surfaces on both sides of the fixing block, thereby increasing the contact with the side wall of the cylindrical casting. The base 1 has two rows of threaded holes 101 evenly arranged. The limiting head 1202 is located between the two rows of threaded holes 101 and is located below the grinding roller 10. Since the processing size of the cylindrical casting may be different, the threaded holes 101 can be pre-reserved on the base 1 according to the size of the cylindrical casting to make the distance between the limiting plates 1201 adjustable.

[0025] Working principle: Based on the diameter of the cylindrical casting, the spacing between multiple limiting plates 1201 is adjusted, and then 1203 passes through the side ears of the limiting plates 1201 and is tightened into the threaded holes 101 on the base 1; the cylindrical casting can then be placed between two adjacent limiting plates 1201, and its movement is restricted by the limiting head 1202. Since the height of the limiting plates 1201 and the limiting head 1202 are both designed to be half the height of the cylindrical casting, the cylindrical casting can remain stable during the grinding process and will not come out from between the limiting heads 1202.

[0026] Then, adjust the height of the connecting plate 8 according to the height of the cylindrical casting so that the grinding roller 10 can contact the top of the cylindrical casting to facilitate grinding at the gate position of the cylindrical casting. After adjusting the height of the connecting plate 8, the bolt on the screw 7 can be rotated to restrict the freedom of the connecting plate 8 to move upward. The hand-held part 11 is used to push the grinding mechanism to move as a whole. At this time, the moving frame 3 can move along the surface of the base 1 through the roller 4 and move horizontally along the slide rod 2 at the same time, gradually grinding the cylindrical casting through the grinding roller 10. Alternatively, depending on the actual situation, the following operation can be performed: the grinding roller 10 can be adjusted to be slightly higher than the cylindrical casting. When moving the grinding mechanism, the hand-held part 11 can be pressed down on the connecting plate 8 to make the connecting plate 8 move down slightly, thereby causing the grinding roller 10 to move down to grind the burrs at the gate position of the cylindrical casting.

[0027] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. 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 modifications and improvements all fall within the protection scope of this utility model.
