Technical Field
[0001] This utility model relates to the field of excavator technology, specifically to a test auxiliary device for an excavator working device. Background Technology
[0002] An excavator, also known as a digging machine or a soil 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. As a representative product of construction machinery, excavators are widely used in engineering construction. To further improve the reliability of the excavator's working device, fatigue tests need to be conducted on the excavator's working device. Currently, the tooling used for fatigue testing of the working device is generally only suitable for one type of vehicle. If a different vehicle model needs to be tested, the tooling needs to be remade. This is not only time-consuming and labor-intensive, increasing the testing cost, but also affects the testing efficiency due to the process of changing the entire tooling. This new testing tooling is suitable for fatigue testing of multiple vehicle models, and the testing tooling can be adjusted up and down, left and right, and front and back mounting distances over a wide range, making it flexible in application.

[0019] The present invention will be further described below with reference to specific embodiments. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
[0020] Example 1: See Figures 1 to 3 This utility model includes structural views, substrate structural views, and exploded view of the slider structure. It is a test auxiliary device for an excavator working apparatus, comprising an actuator 8 and a frame assembly. The frame assembly includes a cast iron platform 1, on which a support 2 is mounted. A substrate is mounted at the bottom of the support 2, and a main body is connected to the upper end of the substrate. Reinforcing ribs connect the main body and the substrate of the support 2. Reinforcing ribs are also connected to the substrate at all four end faces of the main body. This structure effectively improves the strength of the support 2. Strip-shaped holes are provided at the edges of the substrate, and a first... The upper surface of the cast iron platform 1 is provided with a second slide rail arranged vertically. The cast iron platform 1 is a cuboid structure. The edge of the cast iron platform 1 is perpendicular to the second slide rail that is in contact with it. Several second sliders 11 are slidably arranged inside the second slide rail. The base plate is connected to the cast iron platform 1 by the third bolt 9, the third washer 10, and the second sliders 11. The second sliders 11 are provided with threaded holes for connecting bolts. Through the cooperation of the strip hole and the second slide rail, the installation position of the bracket 2 can be adjusted along the second slide rail and the strip hole when the third bolt 9 is loosened.
[0021] The main body has evenly distributed threaded mounting holes on its four outer end faces. The horizontal spacing between each row of threaded mounting holes on the four outer end faces of the main body is the same. The side of the main body is connected to a pad 4 by a first bolt 6 and a first washer 5. The vertical spacing between the threaded holes is also the same. The purpose is to adjust the height and position of the pad 4 by adjusting the mounting hole position of the pad 4. The side end face of the pad 4 has two parallel first slides. Two first sliders 3 are slidably arranged inside the two first slides. The four first sliders 3 are connected to the end base of the actuator 8 by a second bolt 7 and a second washer. The first sliders 3 have threaded holes for connecting bolts.
[0022] The cross-sections of the first slider 3 and the second slider 11 are both T-shaped, and the first slide rail and the second slide rail that slide in cooperation with the first slider 3 and the second slider 11 are both T-shaped grooves.
[0023] To prevent the actuator 8 from accidentally sliding down when adjusting the relative position of the pad 4 and the actuator 8, a limit bolt is threaded onto the inner section of the first slide rail end, which can effectively prevent the first slider 3 and the actuator 8 from sliding down and leaving the first slide rail.
[0024] By changing the mounting position of the pad 4 on the end face of the main body, the height of the actuator 8 can be adjusted significantly, resulting in a noticeable change in position. It is even possible to swap different end faces of the main body for installation, so as to be applicable to the working devices of more specifications and models of excavators. Since the other end of the actuator 8 is connected to the excavator working device, it is possible to test the working devices of excavators of different sizes and models, which saves time, effort, and costs, and is flexible in application.
[0025] By changing the relative position of the first slider 3 and the pad 4, the actuator 8 can slide within a small range along the direction of the first slide. The bracket 2 can be adjusted along the second slide by the second slide provided on the cast iron platform 1.
[0026] Actuator 8, also known as actuator, is a key component of active control system. It applies force to the controlled object according to the instructions of the control system, thereby realizing the control of the mechanical system. In the industry, it is mostly used to conduct fatigue tests on the working device of excavators. The actuator 8 used for testing is generally a hydraulic actuator 8 or an electro-hydraulic servo actuator. This type of actuator 8 is mainly used in the industry for fatigue testing of mechanical components.
[0027] This utility model uses a cast iron platform 1 with a first slide rail arranged in a cross pattern. With the help of sliders and bolts, the bracket 2 is fixed on the platform. Adjusting the position of the first slider 3 can achieve the purpose of adjusting the installation position of the bracket 2. At the same time, it uses a pad 4 that can adjust the installation position, a second slider 11 that can adjust the up and down position of the actuator 8, and a second slide rail. It is suitable for fatigue testing of working devices on various vehicle specifications. It realizes the function of being applicable to fatigue testing of working devices on various vehicle models and can adjust the up and down, left and right, and front and back installation distance and position of the actuator 8.
