Abstract
The utility model relates to an auxiliary device for the processing of a boring lathe, in particular to a boring hole grinder for accurate grinding. The grinder comprises oil stones for grinding, as well as a grinder body, wherein telescopic pipes in radial arrangement and distribution are fixedly connected on the grinder body, a pressure spring is arranged in each telescopic pipe, and a free end of each pressure spring is in contact joint with the corresponding oil stone. Compared with the prior art, the utility model has the advantages that the structure is simple; the grinder can be mounted at the end part of a boring rod, so that as the boring rod rotates, the oil stones can be tightly pressed on the inner wall of inner holes for accurate grinding under the centrifugal force; and the grinding accuracy is high, so as to greatly improve the quality of workpieces to be processed, and increase the grinding rate and working efficiency of the workpieces.
Description
Technical field
The utility model relates to a kind of auxiliary equipment of boring machine processing, specifically a kind of bore hole mill that is used to finish grind.
Background technology
The surface accuracy and the fineness of the workpiece that processes through boring machine are lower, and the whole workpiece crudy is low, and influence is sold.And existing plain grinding device is difficult to endoporus is finish grinded, and has a strong impact on working (machining) efficiency and crudy.
Summary of the invention
The utility model is at the deficiencies in the prior art, provide a kind of can be in endoporus, realize bore hole mill that endoporus is finish grinded thereby rotate with boring bar.
Realize that the technical scheme that above-mentioned purpose adopts is: a kind of bore hole mill, comprise the oilstone that is used to grind, described mill comprises the mill body, is connected with the telescoping tube of arranging radially on this mill body, be provided with stage clip in the described telescoping tube, the free end and the oilstone of this stage clip touch.
Compared with prior art, the utility model is simple in structure, can be installed in the end of boring bar, rotation along with boring bar, utilizing action of centrifugal force that oilstone is pressed on the endoporus inwall finish grindes it, the grinding accuracy height has improved the quality of processing work greatly, improves the grinding rate and the operating efficiency of workpiece.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the structural representation of expansion link.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Referring to accompanying drawing 1-3, this bore hole mill comprises the oilstone that is used to grind, mill comprises mill body 1, this mill body 1 be loop configuration, be connected with the telescoping tube 3 of arranging radially on its inner periphery, the number of telescoping tube 3 is nine in the present embodiment.Be provided with stage clip 4 in the telescoping tube 3, the free end of this stage clip 4 and oilstone 2 are affixed.
The end of telescoping tube 3 all is provided with an angle with the center of mill body 1, and its angle is 5-15 °.This mill is installed in the end of boring bar, and because the existence of this angle, when mill rotates with boring bar, under action of centrifugal force, be convenient to oilstone 2 and under the impetus of stage clip 4, eject, strengthened the pressure between oilstone 2 and the endoporus inwall, improve Grinding Quality.
Decide the number of telescoping tube according to the size in the aperture of processing endoporus, if the aperture is big, a plurality of telescoping tubes can be linked together, each stage clip apical grafting together.
In order to increase work efficiency, a plurality of identical mills can be sleeved on the boring bar side by side and to work simultaneously.
Claims (2)
