Description

Technical Field

[0001] The utility model relates to the technical field of mechanical casting auxiliary devices, in particular to a machine grinding tool for large end cover castings, specifically to a machine grinding tool for gearbox case end cover castings of loaders of 3 tons and above. Background Art

[0002] The gearbox case end cover castings of loaders of 3 tons and above are heavy, generally weighing more than 50 kg. After the castings are poured, the flash risers need to be polished. In the prior art, manual operation is still very common to complete mechanical polishing. However, due to the heavy castings, it is difficult for workers to carry and polish them, resulting in low operating efficiency. Summary of the invention

[0003] The utility model aims to provide a large end cover casting machine grinding tool which has the advantages of simple and compact structure, low manufacturing cost, convenient and efficient operation of large end cover casting machine grinding.

[0004] To achieve the above objectives, the utility model provides a large end cover casting machine grinding tooling comprising a fixed base plate 1, a support plate 2 and a limit block 3; the fixed base plate 1 is a circular plate, and is provided with a plurality of through holes for installing the support plate 2 and the limit block 3; the support plate 2 is provided with two pieces, and the upper and lower end faces of each support plate are provided with a plurality of threaded holes, the upper end face threaded holes are used to install the support plate 2, and the lower end face threaded holes are used to install the entire tooling on the grinding machine during operation, and the two support plates 2 are vertically connected to the lower plane of the fixed base plate 1 by screws and are arranged symmetrically; the limit block 3 is provided with three pieces, and the lower end face of each limit plate is provided with a threaded hole, and the limit block 3 is installed on the upper plane of the fixed base plate 1 by screws, and the arrangement positions of the three limit plates correspond to the three holes of the large end cover casting.

[0005] The upper and lower end surfaces of the support plate 2 are each provided with four threaded holes.

[0006] The lower end surface of the limiting block 3 is provided with two threaded holes.

[0007] The utility model discloses a large end cover casting machine grinding tool, which has the following technical features and beneficial effects:

[0008] 1. By installing the large end cover casting machine grinding tooling on the grinding machine, one person can easily complete the grinding operation of the large end cover casting, greatly reducing the labor intensity and making the grinding operation convenient and efficient.

[0009] 2. The structure is simple and compact, easy to manufacture and install, and low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 The utility model is a three-dimensional structural schematic diagram of a large end cover casting machine grinding tool.

[0011] Reference numerals: fixed base plate 1 , support plate 2 and limit block 3 . DETAILED DESCRIPTION

[0012] The specific implementation method of the large end cover casting machine grinding tool of the utility model is further described in detail below with reference to the accompanying drawings.

[0013] Figure 1 As shown, the utility model is a large end cover casting machine grinding tool comprising a fixed base plate 1, a support plate 2 and a limit block 3; the fixed base plate 1 is a circular plate, and is provided with a plurality of through holes for installing the support plate 2 and the limit block 3; the support plate 2 is provided with two pieces, and the upper and lower end faces of each support plate are provided with four threaded holes, the upper end face threaded holes are used to install the support plate 2, and the lower end face threaded holes are used to install the entire tool on the grinding machine during operation, and the two support plates 2 are vertically connected to the lower plane of the fixed base plate 1 by screws and are arranged symmetrically; the limit block 3 is provided with three pieces, and the lower end face of each limit plate is provided with two threaded holes, and the limit block 3 is installed on the upper plane of the fixed base plate 1 by screws, and the arrangement positions of the three limit plates correspond to the three holes of the large end cover casting.
