Technical Field

[0001] The utility model relates to the technical field of hydraulic cylinder processing, and more specifically, to a drilling device for processing the hydraulic cylinder of an excavator. Background Art

[0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When using it to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various machines.

[0003] During the processing of the piston in the hydraulic cylinder, it is necessary to drill two holes symmetrically on one end of the piston, and use a countersunk drill head to process the two holes after drilling. However, when drilling, the holes are often drilled one by one, and the processing efficiency is not high. Therefore, in view of the above problems, a drilling device for processing an excavator hydraulic cylinder is specially proposed. Utility Model Content

Obviously, the specific implementation mode described is only a part of the implementation mode of the utility model, rather than all styles.

[0025] Example:

[0026] The following is combined with Figure 1-3 The utility model is described in further detail.

[0027] See also Figure 1-3 The utility model provides a technical solution: a drilling device for hydraulic cylinder processing of an excavator, comprising a mounting plate 2 and a piston block 3, a controller 8 is mounted on the top of the mounting plate 2, the controller 8 can be a control device such as a computer, a first adjustment mechanism 7 and a second adjustment mechanism 7 are mounted on the mounting plate 2, two first motors 9 and two second motors 5 are respectively mounted on the first adjustment mechanism 7 and the second adjustment mechanism 7 by fixing bolts, a drilling rod 10 and a countersunk drill rod 6 are mounted on the output shafts of the first motor 9 and the second motor 5, a fixing block 12 is integrally connected to the mounting plate 2, and the piston block 3 is sleeved on the fixing block 12, and fixed A threaded rod 11 is integrally connected to the block 12, a limit plate 4 is overlapped on the top of the piston block 3, a threaded cap 13 is overlapped on the top of the limit plate 4, and the threaded cap 13 is threadedly connected to the threaded rod 11. Under the joint action of the first adjusting mechanism 7, the second adjusting mechanism 7, the first motor 9, the second motor 5, the drilling rod 10 and the countersunk drilling rod 6, when the fixed piston block 3 is subjected to hole processing, two drilling rods 10 can simultaneously process two holes, and countersunk holes can be processed in the holes after the processing holes. The whole process does not require drilling operations one hole after another, which saves time and improves the work efficiency of hole processing.

[0028] Specifically, the first adjusting mechanism 7 and the second adjusting mechanism 7 have the same structure. The first adjusting mechanism 7 includes a support plate 706, which is mounted on the mounting plate 2 by fixing bolts. The top of the support plate 706 is integrally connected to a limiting block 703, and the limiting block 703 is slidably connected to a sliding frame 707.
