Description

Technical Field

[0001] The utility model relates to the technical field of excavator production, in particular to a pin hole punching device for an excavator arm. Background Art

[0002] An excavator, also known as an excavating machine or backhoe, is an earth-moving machine that uses a bucket to dig materials above or below the bearing surface and load them onto transport vehicles or unload them into a stockpile. The materials excavated by an excavator primarily include 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 for an excavator are operating weight (mass), engine power, and bucket capacity. During operation, the bucket and arm are connected to each other through pins, necessitating the machining of pin holes in the excavator arm.

[0003] However, due to the large number of excavator models and the different sizes and shapes of the arms, the existing drilling devices often have different pin hole positions. Existing drilling devices can only drill holes on one plane, making it difficult to automatically change angles and requiring manual flipping, which is inconvenient for speeding up work efficiency and increases labor costs. Therefore, we propose a new excavator arm pin hole drilling device. Utility Model Content

[0022] Specifically, such as Figure 2As shown, the rotating assembly 2 includes a rotating plate 2.1, a rotating shaft 2.2, and a motor 2.3. The two sides of the rotating plate 2.1 are rotatably connected to the side walls of the inner cavity of the accommodating tank 6 via the rotating shaft 2.2. The motor 2.3 is fixedly connected to one side of the workbench 1. The output end of the motor 2.3 extends through the inner cavity of the accommodating tank 6 and is rotatably connected to a rotating shaft 2.2. When drilling is required on the inclined surface of the excavator arm, the motor 2.3 is started, driving the rotating plate 2.1 to rotate about the rotating shaft 2.2. When the desired drilling surface is parallel to the workbench 1, the motor 2.3 is stopped, and drilling can continue. While ensuring a stable fixation, there is no need to manually flip the excavator arm, reducing labor costs and effectively improving drilling efficiency.

The fixing plates 1 4.2 are symmetrically fixedly connected on both sides of the top of the placement plate 4.1. A threaded rod 2 4.4 is connected to one fixing plate 1 4.2 through threaded engagement. One side of the threaded rod 2 4.4 is rotatably connected to the fixing plate 2 4.3 through a bearing. The side of the fixing plate 2 4.3 facing the fixing plate 1 4.2 is fixedly connected with a rubber anti-slip pad, and the other side of the threaded rod 2 4.4 is fixedly connected with the turning handle 4.7.

The slide 4.5 plays a good guiding and limiting role for the slider 4.6, and the top of the slider 4.6 is fixedly connected to the bottom of the fixing plate 2 4.3. After placing one end of the excavator arm on the top of the placement plate 4.1, turning the handle 4.7 drives the threaded rod 2 4.4 to rotate, thereby pushing the fixing plate 2 4.3 to move in the direction of the fixing plate 1 4.2 until the fixing plate 2 4.3 and the fixing plate 1 4.2 fix the side wall of the excavator arm. This is convenient for connecting and fixing different excavator arms and has strong practicality.

[0024] The moving assembly 1 (3) includes a motor 2 (3.1), a threaded rod (3.2), and a moving block (3.3). The motor 2 (3.1) is fixedly connected to the inner wall of the mounting slot (5). The output end of the motor 2 (3.1) is fixedly connected to one end of the threaded rod (3.2). The other end of the threaded rod (3.2) is rotatably connected to the inner wall of the mounting slot (5) via a bearing. The moving block (3.3) is threadedly engaged with the threaded rod (3.2), and the top of the moving block (3.3) is fixedly connected to a placement plate (4.1). To secure the excavator arm, the motor 2 (3.1) is activated to rotate the threaded rod (3.2), thereby moving the moving block (3.3) and the fixing assembly (4) attached thereto. Depending on the size of the excavator arm to be secured, both fixing assemblies (4) are moved to positions corresponding to the ends of the excavator arm.

[0025] Specifically, such as Figure 4As shown, the moving component 2 8 includes a motor 3 8.1, a threaded rod 3 8.2, a sliding rod 8.3, and a moving block 2 8.4. The threaded rod 3 8.2 is rotatably connected between the two brackets 7 through a bearing. The two sliding rods 8.3 are symmetrically fixedly connected between the two brackets 7 and are located on both sides of the threaded rod 3 8.2. The two sliding rods 8.3 and the threaded rod 3 8.2 are on the same horizontal line. The moving block 2 8.4 is slidably sleeved on the threaded rod 3 8.2 and the sliding rod 8.3, and the moving block 2 8.4 is connected to the threaded rod 3 8.2 by threaded engagement. The sliding rod 8.3 plays a good limiting and guiding role for the moving block 2 8.4. The motor 3 8.1 is fixedly connected to one side of the bracket 7. The output end of the motor 3 8.1 passes through the bracket 7 and is fixedly connected to one end of the threaded rod 3 8.2. The bottom of the moving block 2 8.4 is fixedly connected to the top of the cylinder 9.1. A laser locator 11 is fixedly connected to one side of the bottom of the moving block 2 8.4. When starting the drilling work, after fixing the excavator arm through the fixing component 4, start the laser locator 11, then start the motor three 8.1 to drive the threaded rod three 8.2 to rotate so that the moving block two 8.4 drives the drilling component 9 to move. When the laser locator 11 is located at the required drilling position, stop the motor three 8.1, start the cylinder 9.1 and the motor four 9.2, drive the drill bit 9.3 to rotate and drop to the arm position so that the drilling work can be carried out.

[0026] It should be noted that the present invention is a device for punching pin holes for an excavator arm. When the excavator arm needs to be fixed, the starting motor 2 3.1 drives the threaded rod 1 3.2 to rotate, thereby driving the moving block 1 3.3 and the fixing assembly 4 thereon to move. When the size of the excavator arm to be fixed is determined, both fixing assemblies 4 are moved to positions corresponding to the ends of the excavator arm. After one end of the excavator arm is placed on top of the placement plate 4.1, the turning handle 4.7 is turned to drive the threaded rod 2 4.4 to rotate, thereby pushing the fixing plate 2 4.3 toward the fixing plate 1 4.2 until the fixing plate 2 4.3 and the fixing plate 1 4.2 fix the side wall of the excavator arm. This facilitates the connection and fixation of different excavator arms and is highly practical.

[0027] When starting the drilling work, after fixing the excavator arm through the fixing component 4, start the laser locator 11, then start the motor 3 8.1 to drive the threaded rod 3 8.2 to rotate so that the moving block 2 8.4 drives the drilling component 9 to move. When the laser locator 11 is located at the required drilling position, stop the motor 3 8.1, start the cylinder 9.1 and the motor 4 9.2, drive the drill bit 9.3 to rotate and lower it to the arm position so that the drilling work can be carried out. When it is necessary to drill the inclined surface of the excavator arm, start the motor 1 2.3 to drive the rotating plate 2.1 to rotate around the rotating shaft 2.2. When it rotates to the desired drilling surface parallel to the workbench 1, stop the motor 1 2.3 and continue the drilling work. While ensuring a stable fixation, there is no need to manually flip the excavator arm, which reduces labor costs and effectively improves the drilling efficiency.
