Detailed Description
The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
Referring to fig. 1 to 5, an embodiment of the reamer with adjustable blade diameter of the present invention includes a reamer body 1, a mounting through hole 2 is axially disposed inside the reamer body, the mounting through hole includes an adjusting section 3 and a cooling section 4, a cooling jacket 5 is disposed in the cooling section, an adjusting head 6 is disposed in the adjusting section, an adjusting taper surface 7 is disposed on the surface of the adjusting head, an adjusting rod 8 is further disposed in the cooling jacket, one end of the adjusting rod extends out of the cooling jacket and is connected with a locking adjusting nut 9, the other end of the adjusting rod extends out of the cooling jacket and is fixedly connected with the adjusting head, and an elastic pad 10 is disposed between the end of the adjusting head; a plurality of mounting grooves 11 are formed in the cutter body corresponding to the adjusting section, blades 12 are arranged in the mounting grooves, the blades are abutted to the adjusting taper surfaces of the adjusting heads, and locking screws 13 are arranged on the inner walls of the mounting grooves. When the tool is used, when the blade diameter is not enough, the locking adjusting nut is directly adjusted, so that the adjusting rod drives the adjusting head to move towards the tail of the tool body, namely the adjusting nut is locked, the elastic pad is continuously compressed at the moment, and one end of the adjusting head, which is far away from the adjusting rod, is a large end, so that the blade in the mounting groove is extruded towards the outside by the moving mode, and the effect of increasing the blade diameter is achieved; when the sword footpath was too big, reverse regulation locking adjusting nut for the regulation head moves towards the one side of keeping away from locking adjusting nut, because the cushion is compression state, the lax of locking adjusting nut makes the regulation head can the automatic movement, and keep having the pretightning force on the locking adjusting nut all the time, can not become flexible, and the removal of regulation head makes the blade can move towards the axle center, consequently reaches the effect of reducing the sword footpath.
By adjusting the diameter tolerance of the reamer, the precision satisfied by a customer can be achieved, and the service life of the cutter is greatly prolonged within a reasonable abrasion range.
The side edge of foretell blade and regulation tapering face butt is provided with the cooperation tapering face, is convenient for improve regulation precision and stability in use.
When the cutter uses, generally all need use the coolant liquid, this cutter provides an interior cold junction constructs, is provided with cooling bath 14 in cooling jacket's pipe wall, is provided with import 141 and export 142 on the cooling jacket that the cooling bath corresponds, is provided with oil outlet channel 15 on the cutter body that the export corresponds, still is provided with the sealing member between cooling jacket and the cutter body, and the mounting position precision of cooling jacket can be guaranteed to the sealing effect of cooling fluid can also be guaranteed, does not leak outward. Cooling fluid gets into from the import, discharges from the export behind the cooling bath, and the export is direct to dock out oil channel, goes out oil channel and can lead cooling fluid to the blade on for it is lubricated to obtain cooling down during processing.
In order to improve the matching degree of the cutter and equipment, a locking counter bore 16 is arranged on the cutter body corresponding to the locking adjusting nut, the locking adjusting nut is abutted to the end part of the cooling sleeve, a flow passage 17 communicated with an inlet is arranged between the locking adjusting nut and the locking counter bore, oil is directly communicated with the inlet through the flow passage, the cooling sleeve is suitable for use, the complexity of the whole structure is reduced through the design, and the cooling sleeve is convenient to produce and adjust and compact in structure.
