Description

Technical Field

[0001] This utility model relates to the field of excavator boom and stick machining technology, and in particular to a universal machining tooling for excavator boom and stick. Background Technology

[0002] An excavator, also known as a digging machine or excavator, is an earthmoving machine that uses a bucket to excavate materials above or below the machine's bearing surface and load them into transport vehicles or unload them into a stockpile. The materials excavated by excavators are mainly soil, coal, silt, and pre-loosened soil and rock. In recent years, the development of construction machinery has been relatively rapid, and excavators have become one of the most important types of construction machinery. The three most important parameters of an excavator are: operating weight (mass), engine power, and bucket capacity.

[0003] A search revealed a public (announcement) document (CN215357298U) disclosing a universal machining fixture for excavator booms and sticks. The fixture includes a work platform with symmetrically symmetrically formed bottom grooves at its top. A bottom block is embedded within each groove, positioned below a support platform. The top of the support platform is fitted with and supports the excavator boom. A connecting plate is welded between the bottom block and the boom sleeve. The boom sleeve is rotatably connected to the outside of a lead screw within a through groove. A support platform with a bottom block is positioned on the work platform. After the excavator boom is fitted with the support platform, the control power of the motor within the support platform is connected. When the motor is energized, it drives the lead screw in the through groove to rotate clockwise via a coupling. The bottom block in the bottom groove is connected to the boom sleeve via the connecting plate. Under the upward spiral force of the lead screw, the boom sleeve, carrying the bottom block, lifts the support platform upwards, increasing its height. When the motor rotates counterclockwise under the control power, the boom sleeve, driven by the spiral force of the lead screw, lowers the bottom block and support platform.

[0004] Although the above solution drives the lead screw to rotate through the coupling, and then drives the support platform to rise and fall through the bottom block and the rod sleeve, it is inconvenient to clamp and fix excavator booms of different sizes, and has low applicability. Therefore, we propose a universal machining tooling for excavator booms. Utility Model Content

[0005] The main purpose of this utility model is to provide a universal machining fixture for excavator booms and sticks. By setting up a lifting unit and a fixing unit, it solves the problem of inconvenience in clamping and fixing excavator booms and sticks of different sizes and low applicability.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A universal machining fixture for excavator boom and stick includes a main unit, a lifting unit disposed above the main unit, and a fixing unit disposed on the side of the main unit;

[0008] The lifting unit includes a fixed box installed on the top of the main unit, a rotating shaft movably installed on the bottom wall of the fixed box, a worm gear installed on the side wall of the rotating shaft, a drive component installed in the fixed box, a threaded shaft installed on the top of the rotating shaft, a movable component movably installed on the circumferential side of the threaded shaft, a movable rod installed on the top of the movable component and movably passing through the top of the fixed box, and a support base installed on the top of the movable rod.

[0009] The fixing unit includes a fixing groove formed on the side wall of the support base, a threaded rod movably disposed inside the fixing groove and having two sections with opposite directions of rotation, a second drive motor installed at the input end of the threaded rod, and a clamping member disposed on the threaded rod.

[0010] Preferably, the main unit includes a workbench and a base mounted on the bottom of the workbench.

[0011] Preferably, the main unit further includes a storage box installed on top of the workbench.

[0012] Preferably, the driving component includes a worm gear movably disposed inside the fixed housing and meshing with a worm wheel, and a first drive motor installed at the input end of the worm gear.

[0013] Preferably, the clamping member includes a movable seat mounted on the circumferential side of the threaded rod, and a clamping plate mounted on the side wall of the movable seat.

[0014] Preferably, there are two sets of clamping members, and the two sets of clamping members are symmetrically arranged about the bisecting plane of the threaded rod.

[0015] Preferably, the fixing unit further includes a limiting washer installed on the side wall of the fixing groove, and the limiting washer is sleeved on the circumferential side of the threaded rod.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this invention, through the lifting and fixing units, when the support platform needs to be raised or lowered, the first drive motor drives the worm gear to rotate, and the worm gear meshes with the worm wheel, thereby causing the rotating shaft to drive the threaded shaft to rotate synchronously. At this time, the moving part can drive the support seat to move up and down along the threaded shaft through the moving rod until it reaches a predetermined height and stops, thus realizing convenient lifting and lowering of the support platform. When it is necessary to clamp excavator booms of different sizes, after placing the boom on the support seat, the second drive motor drives the threaded rod to rotate. Since the threaded rod has two sections of threads with opposite directions, the two moving seats drive the clamping plates to move along the threaded rod towards each other until the clamping plates are in contact with the side wall of the boom, thus realizing convenient clamping of excavator booms of different sizes and improving the applicability of the device.
