Description

Technical Field

[0001] This utility model relates to the field of engine processing, and in particular to a secondary grinding device for marking surfaces of engines. Background Technology

[0002] In the field of engine manufacturing technology, secondary processing of the engine marking surface is a crucial step. This process typically occurs after engine assembly, when the original markings need to be removed due to defects in the equipment markings or changes in information. Specific equipment is then used to reprocess the engine's marking surface to ensure it meets design requirements and quality standards. Grinding technology plays a key role in this process, allowing for precise machining of the engine marking surface to achieve the required dimensions and shape.

[0003] In existing technologies, secondary processing of engine marking surfaces typically requires transferring the engine from the assembly site to a specialized rework area and using stamp milling equipment. This processing method mainly involves using a high-speed rotating milling cutter to cut the engine marking surface to achieve the required dimensions and shape. However, this processing method has several problems. First, because the cutting head trajectory of the milling equipment interferes with some engine components, a series of components need to be removed before milling the stamp, such as the air compressor, air compressor inlet water pipe, and air compressor return water pipe. This not only increases the complexity of the operation but may also lead to leaks at oil passages, water passages, and other connections, causing quality problems.

[0004] Therefore, there is an urgent need for a secondary grinding device for marking the engine surface to solve the above-mentioned technical problems. Utility Model Content

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0032] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] This embodiment provides a secondary grinding device for marking the surface of an engine. The control mechanism can achieve precise control without removing any engine parts, which greatly simplifies the operation process and reduces the complexity of operation. At the same time, it avoids leakage at the connection of oil passages, water passages and other connections that may be caused by disassembling parts, thus reducing the occurrence of quality problems.

[0036] like Figure 1 and Figure 2 As shown, the secondary grinding device for the marking surface of the engine includes a bracket 1, a moving component 2, a grinding component 4, and a feed component 3. The bracket 1 is fixedly installed on the engine; the moving component 2 is fixedly installed on the bracket 1; the feed component 3 is movably installed on the moving component 2 in a first direction. The feed component 3 includes a fixing member 31, a first screw 32, and a carrier member 33. One end of the first screw 32 passes through the fixing member 31 and is connected to the carrier member 33 to adjust the feed amount of the carrier member 33 in a second direction; the grinding component 4 is installed on the feed component 3 and is driven by the feed component 3 to move closer to or further away from the marking surface in the second direction.

[0037] Since the feed assembly 3 can be movably mounted on the moving assembly 2 in the first direction, the grinding assembly 4 can move in the first direction. One end of the first screw 32 passes through the fixing member 31 and is connected to the carrier member 33 to adjust the feed amount of the carrier member 33 in the second direction, so the grinding assembly 4 can move in the second direction. In this way, the grinding assembly 4 can be precisely controlled by the feed assembly 3 and the moving assembly 2 without removing any engine parts, which greatly simplifies the operation process, reduces the complexity of operation, and avoids leakage at the connection of oil passages, water passages, etc. that may be caused by disassembling parts, thus reducing the occurrence of quality problems.

[0038] In some embodiments, such as Figure 3 and Figure 4As shown, the fixing member 31 has a threaded through hole that engages with the threaded part of the first screw 32. The first screw 32 has an internal threaded hole. The bearing member 33 is provided with a second screw 34, which is inserted into the internal threaded hole and threadedly engages with it. The direction of rotation of the threaded through hole is the same as that of the internal threaded hole, while the direction of rotation of the internal threaded hole is opposite to that of the external thread of the first screw 32. For example, both the internal threaded hole of the first screw 32 and the second screw 34 are left-handed threads, while both the external thread of the first screw 32 and the threaded through hole are right-handed threads. When the first screw 32 is turned to the right, the second screw 34 will move forward, and vice versa, thus controlling the movement of the bearing member 33 in the second direction to achieve feed control of the bearing member 33.

[0039] In some other embodiments, the fixing member 31 has a threaded through hole that threadedly engages with the first screw 32. The first screw 32 has an internal threaded hole. The carrier member 33 is provided with a second screw 34, which is inserted into the internal threaded hole and threadedly engages with it. The internal threaded hole, the threaded through hole, and the external thread of the first screw 32 have the same direction of rotation, but the pitch of the internal threaded hole is different from the pitch of the external thread. When the first screw 32 is turned clockwise, because the pitch of the second screw 34 is different from that of the first screw 32, the second screw 34 will move forward, and vice versa. This controls the movement of the carrier member 33 in the second direction, thereby achieving feed control of the carrier member 33.

[0040] A grinding depth control compass 35 is provided at the end of the first screw 32 away from the second screw 34, and the grinding depth control compass 35 is threadedly connected to the first screw 32. The grinding depth control compass 35 is prior art and will not be described in detail here.

[0041] In some embodiments, to ensure that the fixing member 31 and the bearing member 33 are in contact at their initial positions and to avoid excessive grinding debris entering due to excessive distance between them, the bearing member 33 is provided with a groove 331 on the side facing the first screw 32 for the first screw 32 to pass through. The end of the second screw 34 facing away from the first screw 32 is installed at the bottom of the groove 331. The diameter of the groove 331 is larger than the diameter of the first screw 32, which facilitates the insertion of the first screw 32 into the groove 331.

[0042] In some embodiments, the carrier 33 is provided with two spaced-apart slots 332, the length of which extends along a second direction. Bolts pass through the slots 332 and connect to the moving assembly 2 to limit the travel of the carrier 33. This prevents the carrier 33 from disengaging from the moving assembly 2 due to over-tightening of the first screw 32.

[0043] In some embodiments, the moving component 2 includes a linear slide rail 21 and a guide member 22. The guide member 22 is slidably connected to the linear slide rail 21. The guide member 22 has a receiving groove 221 for accommodating a fixing member 31 and a carrier member 33. The fixing member 31 is fixedly installed in the receiving groove 221, and the carrier member 33 can move in the receiving groove 221 along a second direction. The receiving groove 221 provides guidance for the movement of the carrier member 33, preventing positional deviation during movement. The guide member 22, slidably connected to the linear slide rail 21, can move in a first direction, thereby driving the grinding component 4 to move together in the first direction. The linear slide rail 21 and the guide member 22 have a simple structure, which reduces the overall volume of the secondary grinding device for the engine marking surface. Since the grinding component 4 can be adjusted in the first and second directions, space limitations are avoided, enabling secondary processing of the marking surface.

[0044] To ensure that the support member 33 moves more smoothly without shaking, the receiving groove 221 is a dovetail groove, and the shape of the support member 33 is the same as that of the dovetail groove. That is, both ends of the support member 33 have inclined sidewalls that fit against the groove wall of the dovetail groove, so as to improve the smoothness of the movement of the support member 33.

[0045] It should be noted that both ends of the linear guide rail 21 are fixedly installed on the bracket 1.

[0046] Specifically, the grinding assembly 4 is fixedly mounted on the carrier 33 by the mounting bracket 5.

[0047] like Figure 1 and Figure 2 As shown, the bracket 1 includes a connecting rod 11 and two support rods 12. A support rod 12 is installed at each end of the connecting rod 11, and the two support rods 12 are installed on the same side of the connecting rod 11. The connecting rod 11 is C-shaped; a specific shape of the connecting rod 11 is provided here, as long as it can secure the grinding assembly 4 to the engine, it is within the protection range. The connecting rod 11 has a connecting hole 111, through which bolts are passed to mount the bracket 1 entirely onto the engine block.

[0048] In addition, such as Figure 5 As shown, the secondary grinding device for the engine marking surface also includes a protective cover 6 and a transparent observation plate 7. The protective cover 6 is mounted on the support rod 12, and the transparent observation plate 7 is mounted on the protective cover 6. The protective cover 6 is used to prevent grinding chips from flying, while the transparent observation plate 7 helps the operator to know the grinding status in real time.

The support rods 12 located on both sides of the connecting rod 11 measure 200mm*40mm*40mm and are made of aluminum alloy. Two 10mm diameter holes are provided on the connecting frame for fixing bracket 1 to the engine block using bolts.

[0051] 2. Install the moving component 2. The moving component 2 includes a linear slide rail 21, a guide member 22, a first parallelism adjusting bolt 23, and a second parallelism adjusting bolt 24. The linear slide rail 21 is model HG25. Through-type T-slots are provided on the support rods 12 on both sides of the connecting rod 11. The first parallelism adjusting bolt 23 is connected to the support rod 12 on the left side of the linear slide rail 21 by a special semi-circular head bolt, and the second parallelism adjusting bolt 24 is connected to the support rod 12 on the right side of the linear slide rail 21 by a special semi-circular head bolt.
