[0051] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0052] See also Figure 1-Figure 7 As shown, according to an embodiment of the present application, an engine cylinder bore honing device is provided, comprising:

[0053] The constant temperature water tank 1 includes a tank bottom plate 11 and a tank side plate 12 arranged on the tank bottom plate 11;

[0054] The magnetic bottom plate 2 is arranged on the bottom plate 11 of the box body;

[0055] The magnetic side panel 3 is vertically arranged on the box bottom plate 11 , and the magnetic side panel 3 is located between the magnetic bottom plate 2 and the box side panel 12 .

[0056] Specifically, the constant temperature water tank 1 includes a tank bottom plate 11 and a tank side plate 12. The tank side plates 12 are vertically mounted on the tank bottom plate 11 and together enclose the internal space of the constant temperature water tank 1. The internal space of the constant temperature water tank 1 is used to store liquid and provide a processing environment for the engine. The magnetic side plates 3 are vertically mounted on the tank bottom plate 11 and are located between the magnetic bottom plate 2 and the tank side plates 12. When the engine is placed in the liquid of the constant temperature water tank 1 for cylinder bore honing, the magnetic bottom plate 2 and the magnetic side plates 3 can use magnetic force to absorb the ferromagnetic abrasive particles generated during the processing, preventing the abrasive particles from flowing freely in the constant temperature water tank 1 and causing secondary grinding, reducing the suspension time of the abrasive particles in the liquid, and thus reducing the probability of secondary grinding. Moreover, the magnetic bottom plate 2 is horizontally installed at the bottom of the constant temperature water tank 1, and the magnetic side plate 3 is vertically installed inside the constant temperature water tank 1, forming a multi-directional abrasive adsorption structure, which can greatly improve the abrasive adsorption efficiency generated during the honing process of the engine cylinder bore and improve the processing quality of the cylinder bore.

[0057] When in use, first adjust the liquid temperature in the constant temperature water tank 1 to an appropriate range, place the engine in the constant temperature water tank 1, start the honing device, and the driving part of the honing device drives the honing head to hone the cylinder bore. The abrasive particles generated during the processing will be adsorbed by the magnetic bottom plate 2 and the magnetic side plate 3. Since the abrasive particles in the liquid are effectively removed, the occurrence of secondary grinding is greatly reduced. The cylinder bore can maintain good surface quality during the honing process, thereby improving the overall manufacturing quality of the engine.

[0058] Among them, the magnetic bottom plate 2 and the magnetic side plate 3 can be detachably installed in the constant temperature water tank 1, so that they can be disassembled after use and taken out of the constant temperature water tank 1, so that the staff can remove the abrasive particles attached to the magnetic bottom plate 2 and the magnetic side plate 3 for the next use.

[0059] Combine Figure 1 、 Figure 2 As shown, in some embodiments, optionally, the magnetic base plate 2 includes:

[0060] a first magnetic plate 21;

[0061] The first fixed side plates 22 are symmetrically arranged on the first magnetic plate 21 , and the first filter elements 23 and the second filter elements 24 are alternately arranged between the first fixed side plates 22 .

[0062] Specifically, the first magnetic plate 21 generates a stable magnetic field, creating a strong adsorption force for ferromagnetic abrasive particles. The first fixed side plate 22 is symmetrically positioned on the first magnetic plate 21, primarily providing mounting support and a fixed framework for the first filter element 23 and the second filter element 24. The first and second filter elements 23, 24 are alternately positioned between the first fixed side plate 22, forming a multi-layered filtration structure. The first filter element 23 can be a large-pore metal mesh or porous plastic filter, primarily used to intercept larger impurities and non-ferromagnetic abrasive particles in the liquid. The second filter element 24 is constructed from filter cotton, capable of filtering out finer particles and further adsorbing and removing abrasive particles.

[0063] The first and second filter elements 23, 24 are detachably connected to the first fixed side plate 22, facilitating regular replacement and cleaning while maintaining the stability of the filtration effect. Furthermore, both sides of the first and second filter elements 23, 24 are connected to the first fixed side plate 22 via sliding buckles.

[0064] Combine Figure 2 、 Figure 4 As shown, in some embodiments, optionally, the first magnetic plate 21 includes:

[0065] A first installation box body 211, wherein a first installation cavity is defined inside the first installation box body 211;

[0066] A first adjusting rod 212 is provided on the first mounting box body 211 and passes through the first mounting cavity;

[0067] The first magnetic block 213 is provided on the first adjusting rod 212 . The first magnetic block 213 is located in the first mounting cavity. By rotating the first adjusting rod 212 , the magnetic strength of the first magnetic plate 21 facing the first fixed side plate 22 can be adjusted.

[0068] Specifically, the first mounting cavity opened inside the first mounting box body 211 provides mounting space for the first adjusting rod 212 and the first magnetic block 213. The surface of the first mounting box body 211 is waterproof and sealed to prevent liquid from seeping into the first mounting cavity and affecting the normal operation of the internal components. The first adjusting rod 212 is mounted on the first mounting box body 211 and passes through the first mounting cavity. The first magnetic block 213 is mounted on the first adjusting rod 212 and is located in the first mounting cavity. The first magnetic block 213 is made of high-performance magnetic materials, such as neodymium iron boron permanent magnets. When the operator rotates the first adjusting rod 212, the first magnetic block 213 moves accordingly in the first mounting cavity. By changing its relative position with the first fixed side plate 22, the first magnetic block 213 adjusts the magnetic field strength of the first magnetic plate 21 toward the side of the first fixed side plate 22. For example, when the first adjusting rod 212 is rotated, the first magnetic block 213 moves toward the first fixed side plate 22, the magnetic field strength increases, and the adsorption force on the ferromagnetic abrasive particles increases; conversely, when the first adjusting rod 212 is rotated, the first magnetic block 213 moves away from the first fixed side plate 22, the magnetic field strength weakens.

[0069] The first adjustment rod 212 is connected to the first mounting box 211 via a sealing sleeve, ensuring rotation of the first adjustment rod 212 while preventing liquid from entering the first mounting cavity. A dial and pointer are provided on the end of the first adjustment rod 212, located outside the first mounting box 211. The dial is marked with different magnetic strength levels. By observing the pointer position, the operator can intuitively understand the current magnetic strength of the first magnetic plate 21, facilitating precise adjustment. Furthermore, the dial can be made of fluorescent material, making it easier to read in dimly lit environments.

[0070] The first magnetic block 213 and the first adjustment rod 212 are connected by a detachable connection, such as a threaded or snap-fit ​​connection. If the first magnetic block 213 experiences magnetic degradation or damage, it can be quickly removed and replaced without replacing the entire first magnetic plate 21, reducing maintenance costs and time. The first magnetic block 213 has a semicircular cylindrical cross-section.

[0071] Combine Figure 1 、 Figure 3 As shown, in some embodiments, optionally, the magnetic side panel 3 includes:

[0072] A second magnetic plate 31;

[0073] The second fixed side plates 32 are symmetrically arranged on the second magnetic plate 31 , and the third filter elements 33 and the fourth filter elements 34 are alternately arranged between the second fixed side plates 32 .

[0074] Specifically, the second magnetic plate 31 generates a stable magnetic field, creating a strong adsorption force for ferromagnetic abrasive particles. The second fixed side plate 32 is symmetrically positioned on the second magnetic plate 31, primarily providing mounting support and a fixed framework for the third and fourth filter elements 33, 34. The third and fourth filter elements 33, 34 are alternately positioned between the second fixed side plate 32, forming a multi-layered filtration structure. The third filter element 33 can be a large-pore metal mesh or porous plastic filter, primarily designed to intercept larger impurities and non-ferromagnetic abrasive particles in the liquid. The fourth filter element 34 is constructed of filter cotton, which can filter out finer particles and further adsorb and remove abrasive particles.

[0075] The third filter element 33 and the fourth filter element 34 are connected to the second fixed side plate 32 in a detachable manner, which facilitates regular replacement and cleaning and maintains the stability of the filtering effect.

[0076] Combine Figure 3 、 Figure 5 As shown, in some embodiments, optionally, the second magnetic plate 31 includes:

[0077] A second installation box body 311, wherein a second installation cavity is defined inside the second installation box body 311;

[0078] A second adjusting rod 312 is provided on the second mounting box body 311 and passes through the second mounting cavity;

[0079] The second magnetic block 313 is set on the second adjustment rod 312. The second magnetic block 313 is located in the second installation cavity. By rotating the second adjustment rod 312, the magnetic strength of the second magnetic plate 31 facing the second fixed side plate 32 can be adjusted.

[0080] Specifically, the second mounting cavity opened inside the second mounting box body 311 provides mounting space for the second adjusting rod 312 and the second magnetic block 313. The surface of the second mounting box body 311 is waterproof and sealed to prevent liquid from seeping into the second mounting cavity and affecting the normal operation of the internal components. The second adjusting rod 312 is mounted on the second mounting box body 311 and passes through the second mounting cavity. The second magnetic block 313 is mounted on the second adjusting rod 312 and is located in the second mounting cavity. The second magnetic block 313 is made of high-performance magnetic materials, such as neodymium iron boron permanent magnets. When the operator rotates the second adjusting rod 312, the second magnetic block 313 moves accordingly in the second mounting cavity. By changing its relative position with the second fixed side plate 32, the magnetic field strength of the second magnetic plate 31 toward the side of the second fixed side plate 32 is adjusted. For example, when the second adjusting rod 312 is rotated, the second magnetic block 313 moves toward the second fixed side plate 32, the magnetic field strength increases, and the adsorption force on the ferromagnetic abrasive particles increases; conversely, when the second adjusting rod 312 is rotated, the second magnetic block 313 moves away from the second fixed side plate 32, the magnetic field strength weakens.

[0081] The second adjustment rod 312 is connected to the second mounting box 311 via a sealing sleeve, ensuring rotation of the second adjustment rod 312 while preventing liquid from entering the second mounting cavity. A dial and pointer are located on the end of the second adjustment rod 312, located outside the second mounting box 311. The dial is marked with different magnetic strength levels. By observing the pointer position, the operator can intuitively understand the current magnetic strength of the second magnetic plate 31, facilitating precise adjustment. Furthermore, the dial can be made of fluorescent material, making it easier to read in dimly lit environments.

[0082] The second magnetic block 313 and the second adjustment rod 312 are connected by a detachable connection, such as a threaded or snap-fit ​​connection. If the second magnetic block 313 experiences magnetic degradation or damage, it can be quickly removed and replaced without replacing the entire second magnetic plate 31, reducing maintenance costs and time. The second magnetic block 313 has a semicircular cylindrical cross-section.

[0083] Combine Figure 1 As shown, in some embodiments, optionally, at least one first reference block 4 and at least one second reference block 5 are provided on the box bottom plate 11, the first reference block 4 and the second reference block 5 are arranged opposite to each other, and the magnetic bottom plate 2 is arranged between the first reference block 4 and the second reference block 5;

[0084] The first reference block 4 comprises:

[0085] A first block 41 is provided on the bottom plate 11 of the box;

[0086] A first rib 42 connected to the first block 41;

[0087] The second reference block 5 comprises:

[0088] The second block 51 is disposed on the bottom plate 11 of the box body and is located on one side of the first block 41;

[0089] The second rib 52 is connected to the second block 51 .

[0090] Specifically, there are two first reference blocks 4 and two second reference blocks 5, each symmetrically mounted on the bottom plate 11 of the box. The first reference blocks 4 and the second reference blocks 5 can secure the magnetic bottom plate 2 while also securing the engine. The first rib 42 is vertically mounted on the first block 41, with its top located above the first block 41. The second rib 52 is vertically mounted on the second block 51, with its top also located above the second block 51. The first block 41 and the second block 51 can support and secure the bottom of the engine. The first rib 42 and the second rib 52 can secure the engine circumferentially, improving its placement stability and machining accuracy.

[0091] The inner surfaces of the first rib 42 and the second rib 52 are finely ground to form smooth and flat positioning surfaces, thereby reducing damage to the engine during fixation.

[0092] Combine Figure 1 As shown, in some embodiments, optionally, a fixing seat 6 is further provided on the bottom plate 11 of the box body, and the fixing seat 6 is located between the magnetic bottom plate 2 and the magnetic side plate 3 , and a flexible pressure plate 7 is provided on the fixing seat 6 .

[0093] Specifically, the fixing seat 6 is symmetrically installed on the bottom plate 11 of the box body, which includes a base and a cover plate. The cover plate is installed on the base by bolts. The cover plate can fix the flexible pressure plate 7 on the base. After the engine is stably placed on the first reference block 4 and the second reference block 5, the flexible pressure plate 7 can be passed through the hole in the middle of the engine, and then the two ends of the flexible pressure plate 7 are fixed on the fixing seat 6, further strengthening the fixing effect of the engine, preventing it from moving due to processing, and improving the processing accuracy.

[0094] Among them, the flexible pressure plate 7 can be made of polyamide fiber, which can pass through the bearing hole at the bottom of the engine. The flexible pressure plate 7 and the bearing hole inner cover can produce a better fitting effect, thereby fixing the engine on the first reference block 4 and the second reference block 5. Moreover, in the process of fixing the engine cylinder body through the flexible pressure plate 7, it can reduce the damage to the surface of the engine cylinder body bearing hole cover.

[0095] Combine Figure 6 、 Figure 7 As shown, in some embodiments, optionally, a constant temperature component 8 is further included, and the constant temperature component 8 includes:

[0096] A cooling water tank 81 is provided with a delivery pipe 82 and a return pipe 83 between the cooling water tank 81 and the constant temperature water tank 1. Regulating valves are provided on the delivery pipe 82 and the return pipe 83. A temperature sensor 84 and a refrigerator are provided in the cooling water tank 81.

[0097] The temperature probe 85 is provided on one side of the constant temperature water tank 1 and is used to monitor the temperature of the liquid in the constant temperature water tank 1;

[0098] Heater 86 , heater 86 is arranged on the constant temperature water tank 1 .

[0099] A universal adjustment arm 87 is provided between the temperature probe 85 and the constant temperature water tank 1 .

[0100] The constant temperature assembly 8 further includes a controller, which is electrically connected to the regulating valve, the temperature sensor 84 , the refrigerator, the temperature probe 85 and the heater 86 .

[0101] Specifically, during conventional engine cylinder bore honing, grinding heat is generated, which affects the honing accuracy. In the engine cylinder bore honing apparatus, the thermostatic assembly 8 includes a cooling water tank 81, a temperature probe 85, a heater 86, a universal adjustment arm 87, and a controller. This assembly monitors the cylinder bore temperature in real time and adjusts the temperature of the liquid within the thermostatic water tank 1 according to processing requirements, effectively reducing temperature fluctuations in the cylinder bore and improving processing quality.

[0102] The cooling water tank 81 and the thermostatic water tank 1 form a circulation loop through the delivery pipe 82 and the return pipe 83. The delivery pipe 82 is responsible for delivering the low-temperature liquid in the cooling water tank 81 to the thermostatic water tank 1 to cool it down; the return pipe 83 returns the heated liquid in the thermostatic water tank 1 to the cooling water tank 81, forming a circulating cooling system for the liquid. The regulating valves on the delivery pipe 82 and the return pipe 83 are controlled by the controller. The temperature probe 85 is installed on the side of the thermostatic water tank 1 and can monitor the temperature changes of the engine cylinder bore in real time and transmit the data to the controller in real time. The heater 86 is installed on the bottom of the thermostatic water tank 1 and is also electrically connected to the controller.

[0103] During operation, temperature probe 85 monitors the engine cylinder bore temperature during machining in real time and transmits the monitored temperature data to the controller, which analyzes and processes the temperature detected by temperature probe 85 in real time. If the temperature exceeds a preset range, or if it exceeds a set upper limit, the controller first increases the opening of the regulating valve on delivery pipe 82, increasing the amount of liquid delivered from cooling water tank 81 to constant-temperature water tank 1. It also increases the opening of the regulating valve on return pipe 83, accelerating the flow of liquid from constant-temperature water tank 1 into cooling water tank 81 and activating the refrigerator to cool the liquid in cooling water tank 81. If the temperature falls below the set lower limit, the controller activates heater 86 and adjusts the heating power based on the temperature deviation. It also adjusts the regulating valve appropriately to reduce the flow rate from cooling water tank 81 to constant-temperature water tank 1, ensuring that the temperature quickly and stably returns to the target range. During operation, a universal adjustment arm 87, manually operated, ensures that temperature probe 85 is always monitoring the machined engine cylinder bore.

[0104] Circulation pumps are installed on both the delivery pipe 82 and the return pipe 83 .

[0105] The heater 86 adopts a high-efficiency electric heating element, such as a ceramic heating tube or a stainless steel heating rod, which has the characteristics of fast heating speed and high thermal efficiency.
