Description

Technical Field

[0001] This utility model relates to the field of engine cylinder block thrust surface machining technology, specifically a combination tool for machining engine cylinder block thrust surfaces. Background Technology

[0002] When the engine is running, the crankshaft experiences axial movement. The cylinder block thrust surfaces are used to install thrust washers to adjust the crankshaft axial clearance. If the axial clearance is too large, it will cause abnormal noise; if it is too small, it will increase the crankshaft rotation resistance, and may even lead to serious problems such as cylinder scoring, burning, or crankshaft seizure. In addition, the thrust surfaces at the camshaft bores are used to install camshaft thrust washers, providing axial support for the camshaft. The machining quality of the thrust surfaces directly affects the installation quality of the thrust washers, indirectly affecting engine performance. When machining the cylinder block of an inline four-cylinder engine, the sides of the ribs on both sides of each cylinder chamber need to be milled. These machined surfaces are called the thrust surfaces of the corresponding cylinder blocks. A combination tool for machining the thrust surfaces of the engine block is required during the machining process.

[0003] Most currently used combination cutting tools cannot adjust the height of the tool. During use, the thrust surface height varies depending on the type of engine block. If the height of the combination cutting tool cannot be adjusted according to the engine height, the engine block height will be too high or too low, making it impossible for the tool to properly mill the thrust surface. This results in poor flexibility and a narrow range of applications for the combination cutting tool, and it is not convenient for milling the thrust surface. In use, traditional machining methods usually involve using a milling machine to process each surface one by one, which is not only inefficient, but also requires precise positioning each time the surface is changed, which consumes a lot of time, making the working efficiency of the combination cutting tool poor. Utility Model Content

[0004] The purpose of this invention is to provide a combined tool for machining the thrust surface of an engine cylinder block, in order to solve the problems raised in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined tool for machining the thrust surface of an engine cylinder block, comprising a fixed plate, a lifting and adjusting mechanism provided on one side of the fixed plate, the lifting and adjusting mechanism comprising a support frame, a support frame fixedly connected to one side of the fixed plate, a first motor bracket fixedly connected to both sides of the support frame, a first motor fixedly connected to the inner side of the first motor bracket, a first motor fixedly connected to the output shaft of the first motor via a coupling, the outer wall of the first motor shaft penetratingly connected to the top of the support frame, a ball screw fixedly connected to the bottom end of the first motor shaft, a ball nut movably connected to the outer wall of the ball screw, a connecting rod fixedly connected to the outer wall of the ball nut, and a housing fixedly connected to one side of the connecting rod.

[0006] As a preferred technical solution, a slide rail is fixedly connected to the top of the fixed plate, and a slider is slidably connected to the outer wall of the slide rail.

[0007] As a preferred technical solution, one side of the slider is fixedly connected to one side of the housing, and a baffle is fixedly connected to the top of the slide rail.

[0008] As a preferred technical solution, the first motor bracket is C-shaped, and there are two first motor brackets.

[0009] As a preferred technical solution, the inner wall of the fixing plate is threaded with bolts, and the number of bolts is four.

[0010] As a preferred technical solution, the interior of the housing is provided with a rotary processing mechanism, which includes a second motor bracket, and the second motor bracket is fixedly connected to the interior of the housing.

[0011] As a preferred technical solution, a second motor is fixedly connected to the inner side of the second motor bracket, and the output shaft of the second motor is fixedly connected to the second motor shaft through a coupling.

[0012] As a preferred technical solution, the outer wall of the second motor shaft is connected through the interior of the housing, and the tool body is fixedly connected to the outer wall of the second motor shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of a lifting and adjusting mechanism, can achieve the function of adjusting the height of the cutting tool according to the height of different engine cylinder blocks. During use, the first motor is started to drive the cutting tool body to rise and fall to a suitable height. During the lifting and falling of the cutting tool body, the sliding of the slider on the outer wall of the slide rail can make the lifting and falling of the cutting tool body more stable and smooth. This can avoid the situation where the height of the combined cutting tool cannot be adjusted according to the height of the engine, resulting in the engine cylinder block being too high or too low, which would prevent the cutting tool from performing milling on the thrust surface normally. This ensures the flexibility and applicability of the combined cutting tool.

[0015] 2. This utility model, through the setting of a rotary machining mechanism, can facilitate the machining of thrust surfaces. During use, by starting the second motor, multiple tool bodies are driven to simultaneously machine multiple thrust surfaces. This avoids the situation where traditional machining methods typically use a milling machine to machine each surface one by one, which is not only inefficient but also requires precise positioning each time a surface is changed, which consumes a lot of time and delays the progress of subsequent work. This ensures the working efficiency of the combined tool. Attached Figure Description

[0021] 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.

[0022] Example: Figure 1 As shown, the present invention provides the following technical solution, including a fixing plate 1, a lifting adjustment mechanism 2 on one side of the fixing plate 1, bolts 4 threadedly connected to the inner wall of the fixing plate 1, the number of bolts 4 being four, and a rotating processing mechanism 3 being provided inside the housing 211.

[0023] Specifically: When this combination tool is needed to machine the thrust surface of the engine cylinder block, it is first necessary to install and fix the combination tool in a specific location. At this time, the bottom of the fixing plate 1 is tightly attached to the specific location, and then the threaded hole inside the fixing plate 1 is aligned with the threaded hole in the specific location. Then, the four bolts 4 are rotated and inserted into the threaded holes respectively to fix the fixing plate 1 in the specific location. Then, the thrust surface of the engine cylinder block is aligned directly below the tool body 304. Then, the height of the tool body 304 needs to be adjusted. The tool body 304 is raised and lowered to a suitable height by the lifting adjustment mechanism 2. Then, the machining work can begin. The thrust surface is machined by the rotation machining mechanism 3 to complete the work.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a lifting adjustment mechanism 2 is provided on one side of the fixed plate 1. The lifting adjustment mechanism 2 includes a support frame 201. The support frame 201 is fixedly connected to one side of the fixed plate 1. First motor brackets 202 are fixedly connected to both sides of the support frame 201. A first motor 203 is fixedly connected to the inner side of the first motor bracket 202. The output shaft of the first motor 203 is fixedly connected to a first motor shaft 204 through a coupling. The outer wall of the first motor shaft 204 is connected through the top of the support frame 201. A ball screw is fixedly connected to the bottom end of the first motor shaft 204. A ball screw 205 is movably connected to the outer wall of a ball nut 206. A connecting rod 207 is fixedly connected to the outer wall of the ball nut 206. A housing 211 is fixedly connected to one side of the connecting rod 207. A slide rail 208 is fixedly connected to the top of the fixing plate 1. A slider 209 is slidably connected to the outer wall of the slide rail 208. One side of the slider 209 is fixedly connected to one side of the housing 211. A baffle 210 is fixedly connected to the top of the slide rail 208. The first motor bracket 202 is C-shaped, and there are two first motor brackets 202.

[0025] Specifically: When it is necessary to adjust the height of the tool body 304 to a suitable height, the first motor 203 is started, causing the first motor shaft 204 to rotate. The first motor shaft 204 then rotates the ball screw 205, which in turn causes the ball nut 206 to descend along its outer wall. The ball nut 206 then causes the connecting rod 207 to descend, which in turn causes the housing 211 to descend. During the descent of the housing 211, the sliding of the slider 209 along the outer wall of the slide rail 208 makes the lifting and lowering of the housing 211 more stable and smooth. The housing 211 then causes the tool body 304 to descend to a suitable height, ensuring that the tool body 304 is in close contact with the thrust surface, thus completing the lifting and adjustment work.

[0026] like Figure 1 and Figure 4 As shown, a rotary machining mechanism 3 is provided inside the housing 211. The rotary machining mechanism 3 includes a second motor bracket 301. The second motor bracket 301 is fixedly connected inside the housing 211. A second motor 302 is fixedly connected to the inner side of the second motor bracket 301. The output shaft of the second motor 302 is fixedly connected to a second motor shaft 303 through a coupling. The outer wall of the second motor shaft 303 is connected through the interior of the housing 211. A tool body 304 is fixedly connected to the outer wall of the second motor shaft 303.

[0027] Specifically: When machining is required, the second motor 302 is started, which drives the second motor shaft 303 to start rotating. The second motor shaft 303 drives the tool body 304 to start rotating, so that the tool body 304 can simultaneously machine multiple thrust surfaces, thereby completing the rotary machining work.

[0028] The working principle of this utility model is as follows: When the combined tool is needed to machine the thrust surface of the engine cylinder block, the combined tool must first be installed and fixed in a specific location. At this time, the bottom of the fixing plate 1 is tightly attached to the specific location. Then, the threaded hole inside the fixing plate 1 is aligned with the threaded hole at the specific location. Next, the four bolts 4 are rotated and inserted into the threaded holes to fix the fixing plate 1 in place. Then, the thrust surface of the engine cylinder block is aligned directly below the tool body 304. The height of the tool body 304 needs to be adjusted. The tool body 304 is raised and lowered to a suitable height. At this time, the first motor 203 is started, causing the first motor 203 to drive the first motor shaft 204 to rotate. The first motor shaft 204 drives the ball screw 205 to rotate. The ball nut 206 descends along the outer wall of the ball screw 205, causing the connecting rod 207 to descend. The connecting rod 207 then causes the housing 211 to descend. During the descent of the housing 211, the sliding of the slider 209 along the outer wall of the slide rail 208 makes the lifting and lowering of the housing 211 more stable and smooth. The housing 211 then causes the tool body 304 to descend. The tool body 304 is lowered to a suitable height so that it is in close contact with the thrust surface, thus completing the lifting and lowering adjustment. Then, the machining work can begin. At this time, the second motor 302 is started, causing the second motor shaft 303 to rotate. The second motor shaft 303 then causes the tool body 304 to rotate, allowing the tool body 304 to simultaneously machine multiple thrust surfaces, thus completing the rotary machining work.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
