Description

Technical Field

[0001] The utility model relates to the technical field of deep hole processing of engine cylinders, in particular to a deep hole processing device for engine cylinders. Background Art

[0002] The engine cylinder block is one of the important components of the engine. The cylinder block, piston, connecting rod, crankshaft, cylinder head and other components together constitute the engine. In some engine cylinder block processing processes, a deep hole processing device is required to perform deep hole rough processing on the designated positions of the engine cylinder block.

[0003] However, when the engine cylinder deep hole processing device in the prior art is performing rough drilling, the drill bit is prone to shaking, which makes the drilled deep hole prone to deviation. In addition, the positioning method in the existing engine cylinder deep hole processing device is mostly a clamping fixed structure, and the positioning effect of this fixed structure is poor, which causes the engine cylinder to be prone to slight displacement during the drilling process. Once this situation occurs, it will also affect the accuracy of deep hole processing, and its practicality is poor. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1.

[0033] The positioning assembly 5 includes a limiting groove 51, a support rod 53, a positioning pressure plate 54, an upper fixing nut 55, a lower fixing nut 56 and a limiting block 57. A limiting groove 51 is provided on the right side of the upper end surface of the processing table 3. The limiting groove 51 matches the limiting block 57.

A support rod 53 is provided in the middle position of the upper end surface of the limiting block 57. The support rod 53 can support the upper fixing nut 55 and the lower fixing nut 56.

[0034] A positioning plate 54 is installed on the upper side of the annular side of the support rod 53, and the positioning plate 54 can press and position the engine cylinder block 1 to be processed. A lower fixing nut 56 is installed on the lower side of the annular side of the support rod 53. A second external thread is provided on the lower side of the annular side of the support rod 53, and the second external thread is engaged with the lower fixing nut 56. The engaged second external thread and the lower fixing nut 56 can fix the bottom of the support rod 53.

A blocking bar 52 is fixedly connected to the right side of the upper end surface of the processing table 3. The blocking bar 52 is connected to the processing table 3 by welding. The blocking bar 52 can block and limit the right end of the engine cylinder block 1 to be processed, so as to prevent the engine cylinder block 1 to be processed from displacing to the right during the rough drilling process.

[0035] Working principle: When performing deep hole rough machining on the engine cylinder block 1 to be machined, the staff first places the engine cylinder block 1 to be machined at the required position on the right side of the upper end face of the machining table 3. During this process, it is necessary to make the right end face of the engine cylinder block 1 to be machined fit with the left end face of the blocking bar 52. Then, the support rods 53 and the positioning pressure plates 54 on the front and rear sides are moved inward respectively, and the positioning pressure plates 54 on the front and rear sides are placed on the upper end face of the engine cylinder block 1 to be machined. At this time, the upper fixing nuts 55 and the lower fixing nuts 56 on the front and rear sides are tightened respectively with the help of an external wrench. During this process, the tightened upper fixing nut 55 will press and fix the engine cylinder block 1 to be machined through the positioning pressure plate 54, and the tightened lower fixing nut 56 will fix the bottom of the support rod 53 (reference Figure 1When the deep hole drill 21 is in place, it is only necessary to control the first electric push rod 24 to extend the first electric push rod 24 so that the deep hole drill 21 can be moved to the right through the linkage plate 23 and the drive motor 22, so that the rotating deep hole drill 21 can perform deep hole rough machining on the engine cylinder 1 to be machined. When the movable push rod 24 contracts, the linkage plate 23 can drive the deep hole drill bit 21 to move left to the initial position through the driving motor 22. When the second electric push rod 214 is controlled to be extended and retracted at this time, the second electric push rod 214 can drive the support plate 26 to move up and down, so that the staff can adjust the working height of the deep hole drill bit 21 according to needs, and in this process, the limit cylinder 212 will limit the follower rod 213 to ensure the stability of the lifting and lowering of the support plate 26. When the first fixing nut and the second fixing nut are loosened again with the help of an external wrench, the front and rear displacement of the engine cylinder block 1 to be processed can be adjusted, so that the deep hole drill bit 21 can perform rough drilling of different positions of the engine cylinder block 1 to be processed. When the engine cylinder block 1 to be processed is drilled, it is only necessary to loosen the first fixing nut and the second fixing nut, and then the support rod 53 and the positioning pressure plate 54 can be disassembled, and the engine cylinder block 1 to be processed after drilling can be transferred.
