Description

Technical Field

[0001] The utility model relates to the technical field of engines, in particular to a stable support for machining precision parts of an engine. Background Technique

[0002] The engine accessory block mainly consists of parts such as a cylinder block, a cylinder liner, a cylinder head, and a cylinder gasket. When machining precision parts of an engine, in order to improve the stability of the parts during machining, a support is usually used to fix the precision parts of the engine.

[0003] During the production of cylinder liners, in order to reduce the friction between the piston and the cylinder liner and to facilitate the connection between the cylinder liner and the cylinder block, it is necessary to polish the cylinder liner to make its surface smooth. The existing stable support can only clamp and fix a single side of the cylinder liner during use, resulting in inconvenient polishing of the cylinder liner. Therefore, we propose a stable support for machining precision parts of an engine to solve the problems raised above. Content of the Utility Model

[0004] The purpose of the utility model is to provide a stable support for machining precision parts of an engine to solve the problem that the existing stable support can only clamp and fix a single side of the cylinder liner during use, resulting in inconvenient polishing of the cylinder liner as mentioned in the above background technique.

Detailed implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution: a stable support for the processing of precision engine parts, including: a support frame 1, a bearing plate 2, a hydraulic telescopic rod 3, a connecting sleeve 4, an ejector rod 5, a push rod 6, a top plate 7, a telescopic rod 8, a first spring 9, an installation groove 10, an inner clamping plate 11, a second spring 12, an outer clamping rod 13, a connecting shaft 14 and a rubber pad 15;

[0024] The support frame 1, a bearing plate 2 is fixedly installed at the top of the support frame 1, and a hydraulic telescopic rod 3 is fixedly installed below the middle of the support frame 1. A connecting sleeve 4 is arranged above the hydraulic telescopic rod 3, and the connecting sleeve 4 is fixedly connected to the support frame 1. The top of the hydraulic telescopic rod 3 is fixedly connected to an ejector rod 5, and a push rod 6 is connected to the outer side of the top of the ejector rod 5. A top plate 7 is arranged above the connecting sleeve 4, and a telescopic rod 8 is connected below the top plate 7. A first spring 9 is connected below the top plate 7, and an installation groove 10 is opened inside the top plate 7. An inner clamping plate 11 is arranged inside the installation groove 10, and a second spring 12 is connected to the inner top of the inner clamping plate 11;

[0025] The outer clamping rod 13 is arranged on the outer side of the top of the hydraulic telescopic rod 3, and the middle of the outer clamping rod 13 is rotatably connected to the support frame 1 through a connecting shaft 14.

[0026] As Figure 1 , Figure 2 and Figure 3 shown, the top of the ejector rod 5 is in a conical structure, and the ejector rod 5 is movably connected to the bottom of the first spring 9 through the push rod 6, which is convenient for driving the top plate 7 to lift and lower. The top plate 7 and the connecting sleeve 4 form a telescopic structure through the telescopic rod 8, and the installation groove 10 inside the top plate 7 is arranged in a "cross" structure, which is convenient for limiting the position where the top plate 7 rises. The inner clamping plate 11 is slidably connected to the top plate 7 through the installation groove 10, and the inner side of the inner clamping plate 11 is in an inclined structure, which is convenient for the ejector rod 5 to push the inner clamping plate 11 to move outward to clamp and fix the cylinder sleeve.

[0027] As Figure 1 , Figure 3 and Figure 4 The outer clamping rods 13 on both the inside and outside are arranged in an arc structure, and the bottom of the outer clamping rod 13 is movably connected to the hydraulic telescopic rod 3. Moreover, the outer clamping rods 13 are arranged at equal angles on the outside of the hydraulic telescopic rod 3, facilitating the outer clamping rods 13 to clamp and fix the cylinder liner. Rubber pads 15 are provided on the outer side of the inner clamping plate 11 and the inner side of the top of the outer clamping rod 13 to avoid damaging the cylinder liner.

[0028] Working principle: When using the stable support for machining precision parts of the engine, as Figure 1 shown, place the center of the cylinder liner to align with the center of the bearing plate 2. By extending the hydraulic telescopic rod 3, the hydraulic telescopic rod 3 drives the ejector rod 5 to move upward. As Figure 3 shown, the ejector rod 5 drives the push rod 6 to push the first spring 9 to drive the top plate 7 to move upward through the push rod 6. When the hydraulic telescopic rod 3 moves to a certain height and the top plate 7 is located inside the cylinder liner, the telescopic rod 8 below the top plate 7 engages with the connecting sleeve 4, preventing the top plate 7 from rising further. At this time, by continuing to extend the hydraulic telescopic rod 3, the push rod 6 on the ejector rod 5 squeezes the first spring 9 to contract, which is conducive to the conical structure at the top of the ejector rod 5 squeezing the inclined structure on the inner side of the inner clamping plate 11, causing the inner clamping plate 11 to move outward. Thus, the inner clamping plate 11 clamps and fixes the cylinder liner from the inside through the rubber pad 15. When the hydraulic telescopic rod 3 extends, the top of the hydraulic telescopic rod 3 drives the bottom of the outer clamping rod 13 to move upward, causing the middle part of the outer clamping rod 13 to rotate around the connecting shaft 14, and the top of the outer clamping rod 13 to open, facilitating the grinding of the outer side of the cylinder liner;

[0029] After the outer surface of the cylinder liner is ground, by retracting the hydraulic telescopic rod 3, the hydraulic telescopic rod 3 drives the top plate 7 to reset. As Figure 4 shown, at the same time, the bottom of the outer clamping rod 13 moves downward, driving the middle part of the outer clamping rod 13 to rotate around the connecting shaft 14, causing the top of the outer clamping rod 13 to close, thereby clamping and fixing the cylinder liner from the outside, facilitating the grinding of the inside of the cylinder liner;

[0030] Note: When the telescopic amount of the hydraulic telescopic rod 3 is at half, it is convenient to place the cylinder liner on the bearing plate 2;

[0031] This is the entire working process of the stable support for machining precision parts of the engine. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0032] The standard parts used in the present utility model can all be purchased from the market.
