The utility model provides a device that is used for small-size shaft end face to expand, drill. The utility model discloses light in weight uses in a flexible way, convenient to carry, is applicable to multiple occasion.
Description
Technical Field
The utility model belongs to the technical field of a machining technique and specifically relates to a device that is used for small-size axle head face to expand, drill.
Background
Shafts are widely used as a common coupling component in various sizes of components. The shaft end face hole is used as a processing positioning hole or a connecting hole, and is processed when leaving a factory, and the hole position and the model are basically determined. The adjustment of the end face hole after installation and use has great difficulty. For example, the disassembly problem of the hot sleeve shaft system and the re-alignment and positioning problem in machining directly influence the secondary installation and precision of the shaft system, and the economic cost is higher. However, in many applications, the requirements of thread model change, thread quantity increase and the like are caused by thread broken tooth repair and bolt strength problems, and the end face of the original shaft must be reamed, tapped or provided with a thread hole. Because of the condition limitation, some finished products do not allow secondary disassembly, and some shafts are reworked on a machine tool again even though the shafts are allowed to be disassembled, so that the labor and the time are wasted.
Disclosure of Invention
In order to overcome prior art's not enough, in order to reach not dismantling the original shaft, realize the demand of axle end face hole site transformation, under the sight that magnetic drill can not the direct use, the utility model provides a device that is used for small-size axle terminal surface to expand, drills.
The utility model provides a technical scheme that its technical problem adopted is:
a device for expanding and drilling small shaft end faces comprises a magnetic drill, a connector and a set screw, wherein the connector is formed by welding a base flat plate and a hoop circular tube structure, an inner hole is integrally machined after welding, the size of the inner hole is configured with a shaft to be machined, and the set screw is arranged on the side wall of the inner hole; the base plate is fixedly connected with the magnetic drill base, and the magnetic drill is installed on the magnetic drill base.
Further, the base flat plate is formed by cutting a steel plate with the thickness not less than 12mm, and the size of the steel plate can cover the magnetic drill base.
And furthermore, the hoop circular tube is formed by cutting a seamless steel tube, is assembled and welded with the base flat plate, and then is provided with a threaded through hole on the side surface and is prepared with a set screw.
The technical conception of the utility model is as follows: the connector is positioned and fastened with the shaft to be processed by a set screw, the magnetic drill is tightly attached to the base plate of the special connector, the position of the magnetic drill is adjusted by means of the plane of the base plate and the centroid of the hoop circular tube, and processing operations such as drilling, expanding or tapping are carried out on a target position.
The beneficial effects of the utility model are that: 1. related parts connected with a shafting do not need to be disassembled; 2. large-scale processing and drilling equipment is not needed; 3. the drilling positioning precision is high, and the operation is convenient; 4. light weight, flexible use, convenient carrying and suitability for various occasions.
Drawings
Fig. 1 is a schematic structural diagram of the present invention. Reference numerals in the drawings: 1, magnetic drilling; 2, a special connector; and 3, tightening the screw.
Detailed Description
