Abstract
The utility model relates to a drill tool special for a bearing seat of a manual operation rail-clamping device which is characterized by comprising a drill template and a locating pin, wherein a central hole is formed in the drill template, a plurality of auxiliary small holes are distributed in the circumference of the central hole of the drill template, a locating pin hole and three auxiliary large holes are evenly distributed on the circumference close to the drill template, and dill bushings are installed inside the small holes and the auxiliary large holes. The drill tool special for the bearing seat of the manual operation rail-clamping device has the advantages of being capable of achieving accurate location of the drilling, preventing the drilling from shifting, ensuring processing quality of an installing hole of the bearing seat of the manual operation rail-clamping device, and improving assembly precision and entire quality of the manual operation rail-clamping device. Meanwhile, the drill tool special for the bearing seat of the manual operation rail-clamping device is convenient and fast to operate, and capable of reducing noise and improving production efficiency.
Description
Technical field
The utility model belongs to crane manufacturing technology field, particularly relates to a kind of Manual rail clamping device bearing block Special drill frock.
Background technology
Manual rail clamping device is considerable parts in the MHT electric block gantry crane, and the assembly precision of Manual rail clamping device directly affects the quality of whole MHT electric block gantry crane.Operating personnel are in the process of processing Manual rail clamping device bearing block, when bearing block is holed, owing to can't accurately locate and the drill bit sideslip, therefore be difficult to guarantee the crudy of Manual rail clamping device bearing block installing hole, so need design one cover special tooling to come asessory shaft bearing drilling operating.
Summary of the invention
The Manual rail clamping device bearing block Special drill frock that the utility model provides a kind of simple in structure, convenient operation and can improve Manual rail clamping device bearing block assembly precision for solving the technical problem that exists in the known technology
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Manual rail clamping device bearing block Special drill frock, it is characterized in that: comprise the bushing plate and the alignment pin that have centre bore on it, be positioned at and uniformly on the circumference of bushing plate centre bore have a plurality of auxiliary apertures, be evenly equipped with a dowel hole and three auxiliary macropores at the circumference near bushing plate, in described auxiliary aperture and the auxiliary macropore drill bushing be housed all.
The utility model can also adopt following technical scheme:
Uniformly on the circumference of described bushing plate centre bore have 5 auxiliary apertures.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, when the Manual rail clamping device bearing block is holed, this drilling tool is fixed by alignment pin and bearing block and located, not only can realize holing and accurately locate, prevent the drill bit sideslip, guarantee the crudy of Manual rail clamping device bearing block installing hole, improve assembly precision and the total quality of Manual rail clamping device; And simple and efficient to handle, reduction noise, enhance productivity.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
Among the figure: 1, alignment pin; 2, bushing plate; 2-1, centre bore; 3, drill bushing; 4, dowel hole; 5, auxiliary aperture; 6, auxiliary macropore.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1 and Fig. 2, Manual rail clamping device bearing block Special drill frock comprises the bushing plate 2 and the alignment pin 1 that have centre bore 2-1 on it.Be positioned at and uniformly on the circumferential edge of bushing plate centre bore have a plurality of auxiliary apertures 5, be evenly equipped with a dowel hole 4 and three auxiliary macropores 6 in the circumferential edge near bushing plate, in described auxiliary aperture and the auxiliary macropore drill bushing 3 is housed all.In the present embodiment, uniformly on the circumferential edge of described bushing plate centre bore have 5 auxiliary apertures 5.
Before the boring of Manual rail clamping device bearing block, operating personnel locate bushing plate and bearing block workpiece with alignment pin 1, then carry out Drilling operation by auxiliary aperture 5 and 6 pairs of bearing block workpiece of auxiliary macropore.So not only can realize holing and accurately locate, prevent the drill bit sideslip, guarantee the crudy of Manual rail clamping device bearing block installing hole, improve assembly precision and the total quality of Manual rail clamping device; And simple and efficient to handle, reduction noise, enhance productivity.
