Description

Technical Field

[0001] The utility model belongs to the technical field of welding tool inspection tools for loader articulated frames, in particular to a finished product inspection tool for a front articulated frame of a loader. Background Art

[0002] After the welding of the front articulated frame of the loader is completed, in order to ensure the installation accuracy of the articulated shaft of the product in the later stage and to evaluate whether the product is qualified, the inclination of the side panel of the articulated frame, the size of the shaft hole and the symmetry of the shaft hole must be inspected in detail. Usually, the inspection is completed by using three-coordinate detection of various form and position tolerances. However, this method is not only time-consuming but also labor-intensive, resulting in relatively low inspection efficiency. In order to solve this problem, the utility model proposes a finished product inspection tool for the front articulated frame of the loader. It is used to inspect the finished welded product of the front articulated frame of the loader, facilitates operation and improves inspection efficiency. It reduces the time and manpower required for the inspection of the front articulated frame of the loader, thereby improving overall production efficiency and product quality.

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] Example

[0016] See also Figure 1-2The utility model provides the following technical solutions: a finished product inspection tool for the front articulated frame of a loader, comprising a central axis 1, an inclination detection rod 2 and a hand-tightening bolt 3. Both ends of the central axis 1 are connected with an axis hole positioning block 4. The axis hole positioning block 4 is a cylindrical structure, which is adapted to the axis hole of the front articulated frame of the loader and is used to detect whether the axis hole of the articulated frame meets the standard. The center of one side of the axis hole positioning block 4 is fixedly connected to the end of the central axis 1, and a positioning hole 5 is provided on the outer edge of the other side surface. A positioning block threaded hole 6 and an articulated frame threaded hole 7 are respectively provided at one end of the inclination detection rod 2. The positioning block threaded hole 6 and the articulated frame threaded hole 7 are both adapted to the external thread on the hand-tightening bolt 3. The hand-tightening bolt 3 is conveniently installed on the rod body of the inclination detection rod 2, and the overall tooling ensures the accuracy and convenience of the detection process.

[0017] In order to ensure that the plane of the inclination detection rod 2 can fit the side panel of the articulated frame so as to measure the inclination of the side panel, in this embodiment, as a preferred technical solution of the present invention, the cross-section of the inclination detection rod 2 is a polygonal structure, and the surface of the inclination detection rod 2 is a smooth surface.

[0018] In order to ensure that the tail end of the hand-tightening bolt 3 can be inserted into the positioning hole 5 to position the inclination detection rod 2, in this embodiment, as a preferred technical solution of the present utility model, the length of the rod body at the thread of the hand-tightening bolt 3 is greater than the hole length of the threaded hole 6 of the positioning block of the inclination detection rod 2 or the threaded hole 7 of the articulated frame.

[0019] In order to ensure the connection strength between the central shaft 1 and the shaft hole positioning block 4, in this embodiment, as a preferred technical solution of the present utility model, the two ends of the central shaft 1 and the shaft hole positioning block 4 are connected by welding.

[0020] In summary, relying on the technical solution of this utility model, during the operation, the first step is to firmly place the welded front articulated frame of the loader on a horizontal base surface. Subsequently, the central axis 1 and the axis hole positioning block 4 are inserted from one end of the axis hole of the front articulated frame to ensure that the axis hole positioning blocks 4 at both ends of the central axis 1 are accurately positioned in the axis holes of the two side panels of the articulated frame. At the same time, the inclination detection rod 2 should be as closely fitted as possible to the surface of the side panel of the articulated frame. When the axis hole positioning block 4 is embedded in the axis hole of the side panel of the articulated frame, it indicates that the axis hole of the articulated frame is symmetrical and the aperture meets the standard, otherwise it is considered unqualified. At the same time, by observing the degree of fit between the inclination detection rod 2 and the side panel of the articulated frame, it is determined whether the inclination of the side panel meets the standard. If there is a gap, it is considered unqualified. Through this method, rapid and accurate detection of the front articulated frame of the loader is achieved.

[0021] Finally, it should be noted that in the present invention, unless otherwise clearly stipulated and limited, terms such as "installation", "setting", "connection", "fixation", and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.
