Description

Technical Field

[0001] This utility model relates to the field of engine manufacturing technology, specifically to a grinding machine for engine crankshaft castings. Background Technology

[0002] Engine crankshaft castings are critical components of engines, converting the reciprocating linear motion of the piston into its own rotational motion to output power. Some outdated factories still use sand casting to produce engine crankshafts. After sand removal, the crankshaft forms a blank, which requires rough machining on a lathe. The crankshaft casting is clamped and rotated, and a cutting tool is used to smooth the surface. Rough machining of the crankshaft's main journals and connecting rod journals is necessary. Currently, some factories lack protective structures during the rough grinding of crankshaft castings, resulting in debris flying everywhere and a messy working environment. Furthermore, due to the numerous eccentric structures on the crankshaft casting, its rotational inertia is significant, potentially causing the crankshaft to be thrown out, resulting in machine damage or personnel injury. This makes the operation dangerous and inconvenient. Utility Model Content

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Please see Figure 1-4In this embodiment of the present invention, a crankshaft casting grinding machine includes two limiting seats 10, a clamp 101 slidably connected to the top of the limiting seats 10, a first limiting shell 11 and a second limiting shell 12 fixedly connected between the two limiting seats 10, a protective shell 13 slidably connected to the top of the second limiting shell 12, a C-shaped plate 14 slidably connected to the top of the first limiting shell 11, multiple grinding components 141 slidably connected to the outside of the C-shaped plate 14, an adjustment module 15 disposed inside the first limiting shell 11, capable of adjusting the grinding components 141, and an auxiliary module 16 disposed between the two limiting seats 10, capable of auxiliary positioning of the crankshaft casting.

[0041] Specifically, a protective shell 13 is slidably connected to the top of the limiting shell 12. The protective shell 13 can be used to guide the grinding waste to the inside of the collection cabinet 111 for collection, making the working environment cleaner. At the same time, the protective shell 13 can cover the loose crankshaft casting, making the operation safer. The two positioning plates 164 can stably support and adjust the position of the crankshaft casting, making it more convenient to position the crankshaft casting using the clamp 101. Example 1

[0042] like Figure 1-3 As shown, in this embodiment, the control module 15 includes multiple locking rods 151, which are fixed to the inner top surface of the C-shaped plate 14. The locking rods 151 pass through the limiting shell 11 and are slidably connected to it. The connecting plate 152 is fixed between the bottom ends of two locking rods 151. Multiple hydraulic rods 153 are fixed inside the limiting shell 11. The output end of the hydraulic rod 153 is fixed to the connecting plate 152. Multiple mounting shells 154 are fixed to the bottom of the C-shaped plate 14. The fixing plate 155 is slidably connected to the top of the mounting shell 154 and is fixed to the adjacent grinding assembly 141. A hydraulic rod 156 is fixed to the inner bottom surface of the mounting shell 154. The output end of the hydraulic rod 156 is fixed to the fixing plate 155. Multiple hydraulic rods 102 are fixed to the top of the limiting seat 10. The output end of the hydraulic rod 102 is fixed to the adjacent clamp 101.

[0043] In this embodiment, the limiting shell 11 limits the clamping rod 151, thereby limiting the vertical sliding of the C-shaped plate 14. The hydraulic rod 153, activated, drives the clamping rod 151 up and down via the connecting plate 152, thus moving the two grinding components 141 up and down. This prevents the grinding components 141 from obstructing the feeding of the crankshaft casting. The mounting shell 154 limits the fixing plate 155, thereby limiting the lateral sliding of the grinding component 141. The hydraulic rod 156, activated, drives the grinding component 141 to move, thus determining whether the grinding component 141 is used individually or not. Two grinding components 141 can be used simultaneously to grind the two crankshaft connecting rod diameters of the crankshaft casting, thereby improving processing efficiency. Activating hydraulic rod 102 can drive the crankshaft casting to move laterally, thereby aligning the grinding components 141 with different parts of the crankshaft casting that need to be processed. Activating hydraulic rod 102 can also drive the jig 101 to move. Through the synchronous operation of multiple hydraulic rods 102, the two jigs 101 can be moved synchronously, thereby moving the crankshaft casting fixed by the two jigs 101 and aligning different parts of the crankshaft casting with the grinding components 141 for grinding.

[0044] like Figure 1-2 As shown, in this embodiment, a collection cabinet 111 is movably connected inside the limiting shell 11, a tempered glass 131 is fixedly embedded on one side of the protective shell 13, multiple limiting rods 133 are fixedly connected to both sides of the protective shell 13, multiple positioning frames 132 are fixedly connected to the top of the limiting shell 11 and the limiting shell 12, the limiting rods 133 pass through the adjacent positioning frames 132 and are slidably connected to them, multiple hydraulic rods 134 are fixedly connected to the top of the limiting shell 12, and the output end of the hydraulic rods 134 is fixedly connected to the outer wall of the protective shell 13.

[0045] In practice, the inner walls of the limiting seat 10 and the limiting shell 12 are both inclined. The protective shell 13 can shield the splashed waste and allow the waste to fall automatically into the collection cabinet 111 for unified collection. Pulling the collection cabinet 111 can remove it from the limiting shell 11, thereby cleaning the waste inside the collection cabinet 111. The tempered glass 131 allows observation of the casting processing inside the protective shell 13. The protective shell 13 can concentrate the splashed waste and prevent the crankshaft casting from being thrown outward and causing injury to the workers when it detaches. By limiting the limiting rod 133 with multiple positioning frames 132, the protective shell 13 can be sliding and limited in the vertical direction. Activating multiple hydraulic rods 134 can adjust the height of the protective shell 13, raising the protective shell 13 to facilitate the loading and unloading of the crankshaft casting. After the crankshaft casting is positioned, the protective shell 13 can be lowered to shield and protect the crankshaft casting. Example 2

[0046] Based on Embodiment 1, in order to provide auxiliary support and adjustment for the crankshaft casting, making it more convenient for the fixture 101 to position the crankshaft casting.

[0047] like Figure 4 As shown, in this embodiment, the auxiliary module 16 includes multiple rectangular shells 161, which are slidably connected to the inner wall of the limiting seat 10. A sleeve 162 is fixed between two rectangular shells 161. Multiple sliding rods 163 are slidably connected to the outer wall of the sleeve 162. A positioning plate 164 is fixed to the top of the sliding rod 163. A bidirectional screw 165 is rotatably connected to the inside of the sleeve 162. The bidirectional screw 165 passes through two sliding rods 163 and is screwed to them. A motor 166 is fixed to the outer wall of the rectangular shell 161. The output end of the motor 166 passes through the rectangular shell 161 and is fixed to the bidirectional screw 165. A hydraulic rod 167 is fixed to the inner bottom surface of the limiting seat 10. The output end of the hydraulic rod 167 is fixed to the bottom of the adjacent rectangular shell 161. Multiple baffles 168 are fixedly sleeved on the outer wall of the sleeve 162.

[0048] In practice, the sleeve 162 is slidable vertically by two rectangular shells 161, which allows the positioning plate 164 to be docked and separated from the connecting rod part of the crankshaft casting. The support of the two positioning plates 164 facilitates the positioning of the crankshaft casting by the two clamps 101. The starting motor 166 drives the bidirectional lead screw 165 to rotate, thereby adjusting the distance between the two positioning plates 164, which facilitates positioning through different parts of the crankshaft casting and has greater adaptability. The starting hydraulic rod 167 drives the two positioning plates 164 to move up and down as a whole. The baffle 168 prevents waste from entering the interior of the limit seat 10 through the connection between the slide rod 163 and the limit seat 10.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
