[0001] The utility model relates to the technical field of engineering mechanical arms, in particular to an adjustable engineering mechanical arm. Background Art

[0002] The engineering mechanical arm is a complex system with high precision, multiple inputs and multiple outputs, high nonlinearity, and strong coupling. The mechanical arm of the excavator is also a kind of engineering mechanical arm. The mechanical arm of the excavator is a complex system, which involves multiple joints and connecting rods. Through precise control and operation, it can complete various excavation and operation tasks. During the working process of the excavator, the dynamic characteristics of the mechanical arm have an important influence on the construction quality. However, when installing the existing excavator mechanical arm and bucket, it is necessary to align the pin holes of one group of the two first, and then put the steel bars thinner than the pin holes into the pin holes, and then put the pins into the other group of pin holes for installation. The former group can also put the pins into the pin holes for installation. However, this installation method can only install the bucket, but cannot adjust the tightness between the bucket and the mechanical arm, resulting in more friction and collision, which will not only accelerate the wear of mechanical parts, but also cause mechanical failure problems. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0024] Combination Figure 1 An adjustable engineering machinery boom comprises a mechanical arm 1, an outer surface of the mechanical arm 1 is sleeved with a mounting and debugging block 2, and a bucket 3 is arranged below the mounting and debugging block 2.

[0025] The utility model is further described below in conjunction with embodiments.

[0026] See also Figure 1-Figure 8 A debugging component 22 for adjusting the tightness of the installation of the bucket 3 is installed at the internal height of the installation and debugging block 2. The debugging component 22 includes a storage plate 221 fixedly installed inside the installation and debugging block 2, a debugging plate 222 movably installed inside the storage plate 221, sliders 2222 fixedly installed on both sides of the debugging plate 222, and a slot 2221 provided on the upper surface of the debugging plate 222. A handle 2223 is fixedly installed on one side of the debugging plate 222. The slot 2221 can be used to adjust the tightness between the bucket 3 and the installation and debugging block 2 when the bucket 3 is installed.

[0027] A fixing component 21 for fixing a debugging component 22 is fixedly installed on one side of the installation and debugging block 2, and connecting blocks 23 are fixedly installed on both sides of the installation and debugging block 2. A circular groove 24 is penetrated through one side of the connecting block 23, and an arc surface 25 is provided on one side of the installation and debugging block 2. The circular groove 24 allows the installation and debugging block 2 to rotate, and the arc surface 25 does not hinder the flipping effect of the installation and debugging block 2.

[0028] Card plate slots 26 are provided on both sides of the installation and debugging block 2, and a column slot 27 is provided on one side of the installation and debugging block 2. The column slot 27 corresponds to the debugging component 22, and the debugging component 22 is longer than the debugging component 22. The card plate slot 26 corresponds to the card slot 2221, and the debugging component 22 can be completely accommodated through the column slot 27.

[0029] A storage groove 2211 is provided on one side of the storage plate 221, and a slide groove 2212 is provided on one side of the storage groove 2211. The slide groove 2212 is slidably connected to the slider 2222. The debugging plate 222 can be stored through the storage groove 2211, and the slide groove 2212 can also allow the debugging plate 222 to slide only in the slide groove 2212 to prevent it from escaping from the inside of the storage plate 221.

[0030] The fixing assembly 21 includes a spring 211 fixedly installed on one side of the installation and debugging block 2, a limit plate 212 fixed on one side of the spring 211, a handle 213 fixedly installed on one side of the limit plate 212, and a clamping plate 214 fixedly installed on one side of the limit plate 212, and the clamping plate 214 corresponds to the clamping slot 2221 and the clamping plate slot 26, and the debugging plate 222 can be clamped by the clamping plate 214.

[0031] A mounting plate 31 is fixedly installed on the upper surface of the bucket 3, and a clamping column 32 is fixedly installed on one side of the mounting plate 31. The clamping column 32 is the same size as the debugging plate 222, and the mounting plate 31 is the same size as the column groove 27. The mounting plate 31 can be stored through the column groove 27. By installing the debugging plate 222 and the clamping column 32, the bucket 3 can be installed more conveniently.

[0032] Specifically, when the bucket 3 needs to be installed, it is only necessary to put the bucket 3 on the ground, let the arm with the installation and debugging block 2 on the lower surface of the mechanical arm 1 remain vertical with the bucket 3, and then the mechanical arm 1 can be lowered to allow the clamping column 32 and the mounting plate 31 on the upper surface of the bucket 3 to enter the column groove 27. At this time, the employee can use the handle 2223 to circle the debugging plate 222 around the clamping column 32. At the same time, the employee can pull the handle 213 with the other hand to make one side of the clamping plate 214 face the clamping plate groove 26. As the debugging plate 222 rotates, the first clamping groove 2221 on the upper surface of the debugging plate 222 will face the clamping plate groove 26. At this time, the fixing component 21 is released, and the spring 21 1 will reset the limit plate 212, and the clamping plate 214 will pass through the clamping plate slot 26 and the clamping slot 2221 to clamp the debugging plate 222, and the other group of clamping columns 32 are installed in the same way. At this time, the installation of the clamping column 32 and the mechanical arm 1 is in the loosest state, so that the engineering mechanical arm can be replaced more effectively when the bucket 3 needs to be replaced frequently. If the bucket 3 is to be installed tightly, it is only necessary to align the last clamping slot 2221 on the upper surface of the debugging plate 222 with the clamping plate slot 26. At this time, the bucket 3 and the mechanical arm 1 will be in the tightest state, which can improve the accuracy and stability of the operation of the engineering mechanical arm during work, and achieve the effect that the bucket 3 is convenient for installation and can be debugged for tightness.
