Description

Technical Field

[0001] The utility model relates to the technical field of assembly tools, in particular to a loader grab assembly tool. Background Art

[0002] In construction machinery, loaders are commonly used to assemble grabs to grab ores, woods, coals, grains, etc. for handling work. Grabs are used in many occasions, with high efficiency, simple operation and convenient maintenance. Due to frequent use, grabs wear out relatively quickly. When the wear is relatively serious, the whole grab needs to be replaced. The production of grabs is completed by riveting, assembling and welding many parts. When assembling the parts, the riveter draws the reference lines on the platform according to the drawings, and then uses tools such as height gauges, angle gauges and straight rulers to adjust and assemble each part. And for each production of each grab, the reference lines need to be drawn repeatedly, resulting in low efficiency and poor product consistency. At present, the demand for grabs is gradually increasing, and the orders are also increasing. Due to the low production efficiency and long production cycle, the output of manufacturing enterprises cannot keep up, and they cannot deliver goods in time according to customer requirements, resulting in a large backlog and loss of orders, affecting the development of the enterprise. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a loader grab assembly tool that reduces the use of auxiliary tools and greatly improves the manufacturing efficiency and accuracy of grabs.

[0004] To solve the above technical problem, the technical solution provided by the utility model is: a loader grab assembly tool, including a platform plate, on the upper end surface of the platform plate, three guard plate positioning plates are evenly arranged. The three guard plate positioning plates are arranged in parallel, and the extending direction of the three guard plate positioning plates is consistent with the length direction of the platform plate. At the left and right ends of the guard plate positioning plates on the front and rear sides of the upper end surface of the platform plate, cross beam positioning blocks and tooth plate positioning plates are respectively arranged.

[0005] Further, the guard plate positioning plate includes a vertical plate, a connecting plate and an arc contact plate. The vertical plate is connected to the platform plate. An arc contact plate is arranged above the vertical plate. The vertical plate is connected to the arc contact plate through the connecting plate.

[0006] Further, the left and right ends of the vertical plate are respectively connected to the cross beam positioning block and the tooth plate positioning plate.

[0007] Further, the side of the left end of the vertical plate opposite to it is connected to the cross beam positioning block.

[0008] Further, the height of the tooth plate positioning plate is the same as the height of the right end of the vertical plate.

[0009] Further, a trapezoidal groove is arranged on the upper end surface of the cross beam positioning block.

[0010] The advantages of the present utility model compared with the prior art are as follows:

[0011] According to the characteristics of the grab bucket, it is analyzed that the main links causing low production efficiency and poor assembly consistency of the grab bucket are the assembly process. Assembly tooling is designed based on the grab bucket drawings and production process. All assembly precisions are designed into the tooling, and the production tooling is made according to requirements. Workers no longer need to use tools such as drawing lines, height gauges, square rulers, and straight rulers to align and assemble. They can directly place each component of the grab bucket on the tooling to complete the assembly, reducing a large amount of repetitive work, avoiding measurement and dimension calculation errors by workers during alignment and assembly, greatly improving the production efficiency, and facilitating batch production. The size of each assembled grab bucket is the same, greatly improving the interchangeability of the grab buckets, enabling any grab bucket to be well matched, and avoiding the problem of non-matching during subsequent replacement. At the same time, this assembly platform is a separate whole with a small occupied space, convenient for workers to operate, and easy to operate and store. Brief Description of the Drawings
