Description

Technical Field

[0001] The present invention relates to the technical field of engine processing, and specifically to a device for removing burrs on an engine cylinder block. Background Art

[0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, etc. For example, an internal combustion engine usually converts chemical energy into mechanical energy. An engine is applicable to a power generating device or can refer to the entire machine including the power device; however, after the injection molding of an existing engine cylinder, there will be certain burrs adhering to the surface. If not cleaned, the following problems will occur: 1. Uncleaned sharp burrs may scratch the hands of operators. Especially in the assembly process, workers frequently contact the surface of the cylinder block, and the incidence of such work-related injury accidents is relatively high; 2. Burrs will cause the subsequent machining tools to wear more severely. For example, in the boring process, burrs may cause uneven force on the tool, resulting in deviation of the hole diameter size. At the same time, the remaining burrs may block the internal oil passages and water passages of the cylinder block, triggering faults in the engine cooling or lubrication system; 3. Burrs will damage the clearance between the cylinder block and precision components such as pistons and valves, resulting in a decrease in sealing performance after assembly, directly affecting the engine power output and fuel efficiency; 4. Traditional cleaning methods mainly rely on manual operations, such as using sandpaper for grinding and scrapers for removal; the manual cleaning of a single cylinder block takes a long time and the quality is unstable: manual operations are greatly affected by fatigue and responsibility, and it is easy to have problems such as missed cleaning or excessive grinding, resulting in inconsistent surface roughness of the cylinder block; and long-term repetitive actions are likely to cause occupational diseases such as tenosynovitis and lumbar muscle strain for workers.

[0003] Therefore, in order to solve the above problems, a device for removing burrs on an engine cylinder block is proposed. Summary of the Invention

[0029] The connecting rod 303 is connected to the connecting ring 305 through a disassembly component 50.

[0030] The disassembly component 50 includes a guiding member 51 disposed in the connecting ring 305. Limiting rods 52 are slidably disposed on both sides of the guiding member 51. Limiting springs 53 are disposed on each of the limiting rods 52, and the connecting rod 303 is limited by the limiting springs 53.

[0032] Working principle: When in use, first start the second drive motor 209 to make the rope 210 drive the cover plate 211 to move upward, and connect the cylinder block to the support rod 202 to limit the cylinder block. Then start the second drive motor 209 to make the cover plate 211 move downward, and start the first drive motor 206. The first drive motor 206 drives the second rotating disk 301 with the belt 208. When the second rotating disk 301 rotates, it drives the third pipe 310 to rotate. Then start the air extraction pump 104. The air extraction pump 104 pumps the grit in the storage box 101 and transmits it into the third pipe 310 through the first pipe 105, and sprays it out through the nozzle 311 in the third pipe 310, so as to remove burrs from the cylinder block; The guide member 51 is installed inside the connecting ring 305 to provide a sliding guide path for the limiting rod 52; the limiting rods 52 are arranged in pairs on both sides of the guide member 51 and can slide along the guide member. A limiting spring 53 is sleeved on the surface thereof; the limiting spring 53 is sleeved on the limiting rod 52 and pushes the limiting rod to move inward through the elastic force to realize the limiting and fixing of the connecting rod 303; the limiting block 56 is located outside the limiting rod 52 and is used to limit the displacement range of the limiting spring 53 to prevent the spring from falling off. The limiting protrusion 57 is arranged inside the connecting rod 303 and forms a clamping structure with the end of the limiting rod 52. The operation port 55 is opened at the bottom of the connecting rod 303 to facilitate manually pressing the limiting rod 52 to release the limiting state; The usage principle of the disassembly component is as follows: The limiting spring 53 is in a natural extension state, pushing the limiting rod 52 to slide inward along the guide 51, so that the end of the limiting rod 52 is caught in the card slot of the limiting protrusion 57 inside the connecting rod 303; at this time, the connecting rod 303 is stably connected to the connecting ring 305 through the clamping connection between the limiting rod 52 and the limiting protrusion 57, ensuring that components such as the second rotating disk 301 and the third pipe 310 of the removing device 3 will not fall off during rotation, and at the same time ensuring the sealed connection between the limiting pipe 306 and the first pipe 105 to prevent sand leakage; through the operation port 55 at the bottom of the connecting rod 303, use a tool or finger to press the limiting rod 52 outward, compressing the limiting spring 53, so that the end of the limiting rod 52 disengages from the card slot of the limiting protrusion 57; when the limiting rod 52 completely disengages from the card slot, the connecting rod 303 can be pulled out from the connecting ring 305 to complete the disassembly; after disassembly, components such as the nozzle 311 and the third pipe 310 of the removing device 3 can be conveniently cleaned, maintained or replaced, improving the maintainability of the device; using the elastic force of the limiting spring 53 to push the limiting rod 52 to form a mechanical clamping connection with the limiting protrusion 57 to achieve stable fixation of the components; applying an external force through the operation port 55 to compress the spring to release the clamping state, and rapid disassembly can be achieved without tools, improving the operation efficiency; the guide 51 ensures the stable sliding track of the limiting rod 52, and the limiting block 56 prevents excessive displacement of the spring, ensuring the reliability of the connection and the stability of repeated disassembly; Guide 51 and limiting rod 52: The guide provides a sliding track for the limiting rod to ensure a smooth clamping and unlocking process; The limiting spring provides the clamping force, and the limiting block limits the displacement range of the spring to prevent the spring from failing; Operation port 55 and limiting protrusion 57: The operation port serves as the unlocking entrance, and the limiting protrusion serves as the clamping fulcrum. The two cooperate to achieve the functions of pressing to unlock and releasing the lock; Through the above structural design, while ensuring the working stability of the device, the disassembly component 50 significantly simplifies the maintenance process and meets the requirements of the engine block burr removing device for convenience and reliability.

[0033] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention; Any ordinary technician in the industry can smoothly implement the present invention as shown in the accompanying drawings of the specification and described above; However, any equivalent changes made by those skilled in the art within the scope of the technical solution of the present invention by using the technical content disclosed above, such as slight modifications, decorations and evolutions, are equivalent embodiments of the present invention; At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
