Description

Technical Field

[0001] This utility model relates to the field of diesel engine cylinder block grinding technology, and in particular to a grinding device for diesel engine cylinder blocks. Background Technology

[0002] During the grinding process of diesel engine cylinder blocks, since the cylinder block material is mostly cast iron or alloy cast iron, which has high hardness and complex structure, the high-speed friction between the grinding head and the cylinder block surface will generate a lot of heat and metal chips, causing the grinding head temperature to rise sharply. This not only easily leads to accelerated wear of the grinding head and shortens its service life, but also, if the metal chips are not removed in time, the chips will easily adhere to the cylinder block surface, affecting the surface roughness and dimensional accuracy of the cylinder block.

[0003] Existing grinding equipment typically uses coolant to flush the grinding head and grinding area. The flow of coolant carries away heat, achieving cooling, and the liquid washes away metal debris. However, existing technology is not convenient for collecting and filtering the coolant carrying metal debris, resulting in low functionality and increased production costs.

[0004] Therefore, we propose a grinding device for diesel engine cylinder blocks. Utility Model Content

[0028] like Figures 1-6As shown, a drain pipe 11 is fixedly installed at the bottom of one side of the coolant tank 8. The drain pipe 11 extends to the outside of the grinding table 1. A valve 12 is installed at the outer end of the drain pipe 11. A cylinder 13 is fixedly installed on the inner wall of the groove 2. A clamping plate 14 is fixedly installed at the transmission end of the cylinder 13. A mounting groove 15 is opened on one side of the grinding table 1. A geared motor 16 is fixedly installed on one side of the grinding table 1. The output shaft end of the geared motor 16 extends into the interior of the mounting groove 15. A lead screw 17 is fixedly installed at the output shaft end of the geared motor 16. The lead screw 17 is movably connected to the grinding table 1. A nut seat 18 is threadedly installed at the outer end of the lead screw 17. A slide rail 19 is embedded on one side of the grinding table 1 away from the mounting groove 15. A slider 20 is movably installed at the inner end of the slide rail 19. A U-shaped frame 21 is fixedly installed on one side of the slider 20 and the nut seat 18. A through groove 22 is opened at the inner end of the U-shaped frame 21. A geared motor 23 is fixedly installed on one side of the inner end of the 22. A lead screw 24 is fixedly installed on the output shaft end of the geared motor 23. The lead screw 24 is movably connected to the U-shaped frame 21. A protective disc 25 is fixedly installed on the outer end of the lead screw 24 near the geared motor 23. A nut seat 26 is threaded on the outer end of the lead screw 24. An electric push rod 27 is fixedly installed on the bottom end of the nut seat 26. A base 28 is fixedly installed on the transmission end of the electric push rod 27. A grinding motor 29 is fixedly installed on the bottom end of the base 28. A grinding head 30 is fixedly installed on the output shaft end of the grinding motor 29. A connecting ring 31 is fixedly installed on one side of the base 28. A spray nozzle 32 is fixedly installed on the inner end of the connecting ring 31. A water pump 33 is fixedly installed on one side of the grinding table 1. The water pump 33's suction end extends into the interior of the coolant tank 8. A hose 34 is fixedly installed on one side of the water pump 33. The hose 34 is fixedly connected to the spray nozzle 32.

[0029] Working principle: First, when grinding the diesel engine cylinder block, the operator places the diesel engine cylinder block in the center of the groove 2 of the grinding table 1. The cylinder 13 pushes the clamping plate 14 to clamp and fix the diesel engine cylinder block. The electric push rod 27 pushes the base 28 and the grinding head 30 down to contact the surface of the diesel engine cylinder block. The grinding motor 29 drives the grinding head 30 to rotate and grind the diesel engine cylinder block. During the grinding process, the second reduction motor 23 drives the grinding head 30 to move back and forth through the second lead screw 24 and the second nut seat 26. The protective plate 25 can protect the transmission end of the second reduction motor 23 to prevent the second nut seat 26 from hitting the second reduction motor 23. The first reduction motor 16 drives the U-shaped frame 21 and the grinding head 30 to move left and right through the first lead screw 17 and the first nut seat 18. During the movement of the U-shaped frame 21, the slider 20 will move synchronously within the slide rail 19. This improves the stability of the U-shaped frame 21 and the grinding head 30 when moving left and right. During the grinding process, metal dust and high temperature are generated. The water pump 33 draws out the coolant from the coolant tank 8 and flows out from the spray nozzle 32 through the hose 34 to rinse the grinding head 30 and the grinding area. This not only cools down the grinding head 30 but also prevents metal dust from floating out of the grinding table 1. The coolant carrying the metal dust flows through the drain hole 9 to the guide plate 10. Under the action of the guide plate 10, the coolant carrying the metal dust can be introduced into the filter drawer 4. The filter screen 6 filters and intercepts the metal dust in the coolant. The filtered coolant flows back into the coolant tank 8 for reuse. Later, the filter drawer 4 can be pulled out from the grinding table 1, and the filter screen 6 can be removed for cleaning. The positioning frame 3 supports and limits the filter drawer 4.
