Description

Technical Field

[0001] This utility model belongs to the field of metal product processing technology, specifically referring to a deburring device for cast iron parts. Background Technology

[0002] Cast iron parts generally refer to iron components manufactured using the casting process. Cast iron is made by pouring molten cast iron into a pre-made mold and then cooling and solidifying it. This process allows for the one-time molding of complex shapes, resulting in high production efficiency. Cast iron typically contains a high proportion of carbon (usually between 2% and 4%), as well as elements such as silicon and manganese. These components give cast iron good fluidity and castability, and also determine its mechanical properties.

[0003] When cylindrical parts are cast, there may be uneven wall thickness or ellipticity deviation, resulting in inconsistent distribution of grinding allowance. During semi-automatic grinding, it is difficult to maintain uniform pressure of the grinding wheel on the cylindrical surface, causing local over-grinding or under-grinding. When the grinding wheel plane contacts the cylindrical surface, it is easy to produce "line contact" rather than "surface contact" due to curvature mismatch, resulting in excessive local pressure or scratches. Utility Model Content

The upper part of the first grinding rod has grinding threads.

[0009] Furthermore, the grinding assembly also includes a first motor, a placement platform, a lower rotating rod, a grinding wheel, a second motor, a second slider, and a third gripper. The first motor is located on the upper part of the base frame and on the same side as the first grinding rod. The placement platform is fixed to the upper part of the first motor. The grinding wheel is located in front of the first motor and below the placement platform. The lower rotating rod is located below the grinding wheel and is rotatably connected to the base frame. The second motor is located at the rear of the first grinding rod. The second slider is located in the middle of the base frame and is fixed to the lower part of the second gripper. The third gripper is located at the front end of the base frame.

[0010] Furthermore, the conveying assembly includes a positioning block, a blocking plate, a mounting plate, a rotating motor, conveying rollers, and a base plate.

[0013] Furthermore, the rotating motor and the conveyor roller are connected by a power belt.

[0014] Furthermore, the bottom of the spacer assembly is connected to the moving cylinder.

[0015] The beneficial effects of this utility model by adopting the above structure are as follows: (1) The lower rotating rod is part of the grinding assembly. At this time, the lower rotating rod and the cylindrical cast iron part above it rotate at the same time, which will ensure uniform contact between the grinding wheel and the cylindrical surface of the cylindrical cast iron part, maintain the roundness and straightness of the workpiece, and match the cylindrical curvature of the cylindrical cast iron part by adjusting the rotation speed, feed angle and grinding wheel shape (such as flat, cup, disc). (2) Adjust the pressure of the grinding wheel on the lower cylindrical cast iron part to treat local defects such as porosity. In addition, the grinding wheel can be combined with coolant to control the frictional heat between the grinding wheel and the cylindrical cast iron part and avoid deformation of the cylindrical part due to local overheating. (3) When grinding by grinding threads, the grinding threads form a continuous spiral feed motion when they come into contact with the surface of the cylindrical cast iron parts, thereby ensuring uniform force during the grinding process, avoiding local overheating or insufficient grinding, which helps to further improve the surface quality. In addition, the movement of the grinding threads is spiral, and the dust and shavings generated by the cylindrical cast iron parts during the grinding process are more easily carried away. Finally, the grinding threads vibrate less during the working process and move more smoothly, which helps to achieve higher processing accuracy and more consistent surface roughness.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model proposes a deburring device for cast iron parts, including a grinding component 2 and a conveying component 3, wherein the conveying component 3 is located at the front of the grinding component 2; The conveying assembly 3 is used to convey the cylindrical cast iron parts 1 one by one to the grinding assembly 2; The grinding assembly 2 is used to grind the cylindrical cast iron part 1.

[0022] like Figure 1 , Figure 2and Figure 3 As shown, the grinding assembly 2 further includes a first motor 208, a placement platform 209, a lower rotating rod 210, a grinding wheel 211, a second motor 212, a second slider 213, and a third gripper 214.

The grinding wheel 211 is located in front of the first motor 208 and below the placement platform 209.

The second slider 213 is located in the middle of the base frame and is fixed to the lower part of the second gripper 205. The third gripper 214 is located at the front end of the base frame.

[0023] like Figure 3 , Figure 4 and Figure 5 As shown, the conveying assembly 3 includes a positioning block 301, a blocking plate 302, a mounting plate 303, a rotating motor 304, a conveying roller 305, and a base plate 306. The positioning block 301 is located on the upper part of the base frame, the blocking plate 302 is located at the front of the base frame and at the rear of the third gripper 214, the base plate 306 is located in the middle of the base frame and above the second slider 213, the rotating motor 304 is located on the mirror side of the third gripper 214 and below the third gripper 214, the conveying roller 305 is located in the middle of the base frame and at the rear of the blocking plate 302, and the mounting plate 303 is located at the front of the base frame.

[0024] like Figure 3 , Figure 4 and Figure 6 As shown, the conveying assembly 3 also includes an inclined plate 307, a moving cylinder 308, a sliding base 309, a bottom slide rail 310, a mounting frame 311, and a spacing assembly 312. The inclined plate 307 is located at the front end of the base frame. The moving cylinder 308 is located in front of the inclined plate 307 and is located at the lower part of the inclined plate 307. The sliding base 309 is fixed to the bottom of the moving cylinder 308. The bottom slide rail 310 is located at the lower part of the sliding base 309. The mounting frame 311 is located outside the bottom slide rail 310. The spacing assembly 312 is located above the mounting frame 311.

[0025] like Figure 4 , Figure 5 and Figure 6As shown, the first grinding rod 206 is rotatably connected to the front of the mounting plate 303.

[0026] like Figure 4 , Figure 5 and Figure 6 As shown, the rotating motor 304 and the conveyor roller 305 are connected by a power belt.

[0027] like Figure 4 , Figure 5 and Figure 6 As shown, the bottom of the spacer assembly 312 is connected to the actuating cylinder 308.

[0028] While cylindrical cast iron parts 1 have many advantages in casting and use, they also have some inherent disadvantages, mainly including: high brittleness: due to the presence of graphite, the structure of cast iron has good compressive strength, but it also leads to low overall toughness of the material, making it easy to crack or break when subjected to impact or vibration.

[0029] The machining process is quite difficult: due to the hardness of cast iron and the unevenness of its internal structure, problems such as grinding wheel clogging and uneven surface are likely to occur during subsequent finishing.

[0030] Casting defect risk: During the casting process, defects such as shrinkage cavities and porosity may occur, which can affect the mechanical properties and dimensional accuracy of the parts.

[0031] Dimensional and shape deviations: The inherent cooling and solidification process of casting can easily cause uneven shrinkage, resulting in deviations in the size and roundness of cylindrical parts, which will increase the difficulty of subsequent machining corrections.

[0032] In this embodiment, since the bottom of the spacer assembly 312 is connected to the moving cylinder 308, when the moving cylinder 308 works, the spacer assembly 312 will be raised. Multiple sets of cylindrical cast iron parts 1 are placed on the upper part of the spacer assembly 312, and the upper part of the spacer assembly 312 is provided with a slot so that the multiple sets of cylindrical cast iron parts 1 can be fixedly placed on the upper part of the spacer assembly 312.

[0033] Furthermore, since the inclined plate 307 is located at the front end of the base frame, when the partition component 312 is raised, the multiple sets of cylindrical cast iron parts 1 placed on the upper part of the partition component 312 will be higher than the inclined plate 307. The sliding base 309 is fixed to the bottom of the moving cylinder 308, and the bottom slide rail 310 is located at the lower part of the sliding base 309. At this time, the sliding base 309 can slide to the end of the bottom slide rail 310, thereby driving the moving cylinder 308 to move to the end of the bottom slide rail 310.

[0034] When the moving cylinder 308 moves to the end of the bottom slide rail 310, it means that the moving cylinder 308 has moved to the end of the spacer assembly 312. At this time, if the moving cylinder 308 at the end is raised further, the spacer assembly 312 will tilt. When the spacer assembly 312 tilts, the multiple sets of cylindrical cast iron parts 1 on its upper part will slide forward.

[0035] When the cylindrical cast iron part 1 slides forward, it will roll forward to the inclined plate 307. The inclined plate 307 is not installed horizontally, but is higher on the side closer to the moving cylinder 308 and lower on the side closer to the base frame. Therefore, the cylindrical cast iron part 1 will continue to roll down when it is on the inclined plate 307.

[0036] The baffle plate 302 is located at the front of the foundation frame and is close to the inclined plate 307. At this time, the cylindrical cast iron part 1 rolling down from the inclined plate 307 will be blocked by the baffle plate 302. The third gripper 214 is located near the baffle plate 302. At this time, the third gripper 214 will start to work and grab the cylindrical cast iron part 1 blocked by the baffle plate 302. A cylinder is installed at the lower part of the third gripper 214. The cylinder will lift the third gripper 214, and the cylindrical cast iron part 1 grabbed by the third gripper 214 will also be lifted.

[0037] The rotating motor 304 is located on the mirror side of the third gripper 214, and the conveying roller 305 is located in the middle of the base frame and behind the baffle plate 302. At this time, the rotating motor 304 starts to work and drives the conveying roller 305 to rotate. Then the cylindrical cast iron part 1 gripped by the third gripper 214 will be placed on the conveying roller 305 and will be conveyed by the conveying roller 305 to the remaining parts in the rear.

[0038] Furthermore, since the lower rotating rod 210 is located in the middle of the base frame and is located behind the conveying roller 305, the cylindrical cast iron part 1 conveyed by the conveying roller 305 will be conveyed to the lower rotating rod 210. The placement platform 209 is fixed to the upper part of the first motor 208, the grinding wheel 211 is located in front of the first motor 208 and below the placement platform 209, and the lower rotating rod 210 is located below the grinding wheel 211.

[0039] At this time, the first motor 208 starts working and drives the grinding wheel 211 to start rotating. The grinding wheel 211 is located above the lower rotating rod 210. At this time, the cylindrical cast iron part 1 on the lower rotating rod 210 will be ground by the grinding wheel 211. The lower rotating rod 210 is rotatably connected to the base frame. When the cylindrical cast iron part 1 is ground by the grinding wheel 211, it will inevitably start to rotate. At this time, the lower rotating rod 210 will also rotate along with the cylindrical cast iron part 1.

[0040] The lower rotating rod 210 is part of the grinding assembly 2. When the lower rotating rod 210 and the cylindrical cast iron part 1 above it rotate simultaneously, it will ensure uniform contact between the grinding wheel 211 and the cylindrical surface of the cylindrical cast iron part 1, which can maintain the roundness and straightness of the workpiece. Furthermore, the rotation speed, feed angle and wheel shape (such as flat, cup-shaped, or disc-shaped) of the grinding wheel 211 can be adjusted to match the cylindrical curvature of the cylindrical cast iron part 1.

[0041] Furthermore, the pressure of the grinding wheel 211 on the lower cylindrical cast iron part 1 is adjusted to address local defects such as porosity and slag inclusions. In addition, the frictional heat between the grinding wheel 211 and the cylindrical cast iron part 1 can be controlled by combining the grinding wheel 211 with coolant, thus preventing the cylindrical part from deforming due to local overheating.

[0042] The second slider 213 is located in the middle of the base frame and is fixed to the lower part of the second gripper 205. At this time, the cylindrical cast iron part 1, which has been polished by the grinding wheel 211, will be gripped by the second gripper 205. The second slider 213 will then start to work and slide, causing the cylindrical cast iron part 1 on the second gripper 205 to continue to slide backward.

[0043] Then, when the second gripper 205 drives the cylindrical cast iron part 1 to continue sliding backward and slides above the first grinding rod 206, the second gripper 205 stops working and causes the cylindrical cast iron part 1 to fall above the first grinding rod 206. The upper part of the first grinding rod 206 has a grinding thread 207. At this time, the first grinding rod 206 starts to rotate under the influence of the outside, and then the first grinding rod 206 drives the grinding thread 207 to start rotating.

[0044] When grinding is performed by grinding thread 207, the grinding thread 207 forms a continuous spiral feed motion when it contacts the surface of the cylindrical cast iron part 1, thereby ensuring uniform force during the grinding process, avoiding local overheating or insufficient grinding in some areas, and helping to further improve the surface quality. In addition, the movement mode of grinding thread 207 is spiral, and the dust and grinding debris generated by the cylindrical cast iron part 1 during the grinding process are more easily carried away. Finally, grinding thread 207 has less vibration and smoother movement during operation, which helps to achieve higher machining accuracy and more consistent surface roughness.

[0045] The first slide rail 201 is located at the very end of the basic frame, and the first gripper 202 is located on the upper part of the first slide rail 201. The first gripper 202 and the first slide rail 201 are connected by a sliding module. After the cylindrical cast iron part 1 is polished, the second gripper 205 will continue to work and will clamp the cylindrical cast iron part 1 on the first polishing rod 206.

[0046] It is then transported to the rear parts, where the second gripper 205 stops working and lowers the cylindrical cast iron part 1. Then the first gripper 202 grabs the polished cylindrical cast iron part 1 and continues to transport it to other subsequent processes.

[0047] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.

[0049] The present invention and its embodiments have been described above.
