[0010] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and do not limit the utility model.

[0011] The specific implementation of the utility model will be described in detail in combination with specific examples.

[0012] Please refer to Figure 1 and Figure 2 , the utility model embodiment provides a special machine is used for processing cylinder cover elongated oil hole anti drill bit jumping structure, special machine is used for processing cylinder cover elongated oil hole anti drill bit jumping structure includes:

[0013] Fixed seat 1 and guide rod 2, the guide rod 2 is provided with two and end and fixed seat 1 fixed connection, guide rod 2 is set with guide sleeve 3, guide sleeve 3 is set with guide hole, guide sleeve 3 and fixed seat 1 between fixed connection has spring 4;Drilling mechanism 5, it is installed on fixed seat 1 and passes through the guide hole of guide sleeve 3, is used to carry out drilling to cylinder cover.

[0014] When using the special machine is used for processing cylinder cover elongated oil hole anti drill bit jumping structure, fixed seat 1 is installed to special processing equipment, and the whole structure is moved by special processing equipment control, and drilling mechanism 5 is opened, and special processing equipment drives drilling mechanism 5 to move by fixed seat 1, drilling mechanism 5 can gradually approach cylinder cover, so that the position needing drilling of cylinder cover can be drilled, and during the drilling process, with the movement of the whole structure, cylinder cover pushes guide sleeve 3 to slide on guide rod 2 and compresses spring 4, so that the jumping amplitude of drilling mechanism 5 can be reduced through the deformation of spring 4.

[0015] As Figure 1 and Figure 2 As a preferred embodiment of the utility model, the drilling mechanism 5 includes: driving part 51, which is fixedly installed on the fixed seat 1 and is arranged between the two guide rods 2, the driving part 51 is connected with the main shaft 52, and the driving part 51 is used to drive the main shaft 52 to rotate;Elongated drill bit 53 is connected with the main shaft 52, the elongated drill bit 53 is sleeved with movable drill sleeve 54 and fixed drill sleeve 55, the movable drill sleeve 54 is installed at the guide hole of the guide sleeve 3, and is used to maintain the stability of the elongated drill bit 53 during drilling, and the fixed drill sleeve 55 is used to position the drilling position.

[0016] When drilling, the driving member 51 is started, which is specifically a motor, and drives the spindle 52 to rotate, thereby driving the elongated drill bit 53 to rotate, and with the movement of the structure, the elongated drill bit 53 can drill the cylinder head, and the movement of the drill sleeve 54 ensures the stability of the elongated drill bit 53 during drilling, and the fixed drill sleeve 55 can facilitate the positioning of the drilling position.

[0017] In summary, the guide sleeve 3 is internally provided with a guide hole matched with the elongated drill bit 53, which can provide accurate guidance for the elongated drill bit 53 and limit the radial swing of the elongated drill bit 53; one end of the spring 4 is connected to the guide sleeve 3, and the other end is connected to the fixed seat 1, and when the elongated drill bit 53 is subjected to a radial force, the spring 4 can absorb part of the energy through elastic deformation, thereby reducing the amplitude of the elongated drill bit 53; the fixed seat 1 is used to fix the entire drill bit jump prevention structure on a special machining equipment.

[0018] The above only describes the preferred embodiments of the present application and is not intended to limit the present application, and any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
