Abstract
The utility model relates to a punching device for positioning a center hole of an aluminum bar. The punching device comprises a base, wherein stepped holes are formed inside the base; the diameters of the stepped holes are gradually reduced; the stepped holes have the same circle center; a casing pipe is also arranged on the base; a through hole of which the circle center is identical with that of the base is formed in the casing pipe; a punching rod is arranged in the through hole; and a spring is sleeved on the periphery of the punching rod. According to the punching device disclosed by the utility model, a plurality of circular stepped holes with the same circle center are formed inside the base, so that the punching device can be matched with various circular aluminum sections with different diameters for use; the punching rod is arranged in the vertical casing pipe at the middle of the base and a center drill is in threaded connection with the inside of the punching rod, thus the positioning of center points of the aluminum sections is realized by a cone at one end of the center drill; and the operation process is simple and quick.
Description
Technical field
The utility model relates to the machine tools field, relates in particular to a kind of perforating device for location aluminium bar centre bore.
Background technology
For circular aluminum section bars such as disks before entering the lathe manufacturing procedure, all need to be punched in its center, conventional method is to utilize operating personnel's setting-out to get central point, but this method wastes time and energy, operating portion is convenient, the difficulty of determining for the central point of the circular aluminum section bar of different-diameter size affects production efficiency.
The utility model content
The applicant is studied improvement for the problems referred to above, provides a kind of simple in structure, the centre bore perforating device that is used for the circular aluminum section bar easy to use.
The technical scheme that the utility model adopts is as follows:
A kind of perforating device for location aluminium bar centre bore, comprise pedestal, the shoulder hole with same center of circle that diameter successively decreases step by step is set in the inside of pedestal, sleeve pipe also is set on pedestal, have the through hole with the pedestal concentric in the sleeve pipe, in described through hole, install jumper bar, the outer race shock mount of jumper bar.
Its further technical scheme is:
Have threaded mounting hole in the described jumper bar, connect centre drill in described threaded mounting hole internal thread;
One end of described centre drill has bullet;
Described shoulder hole is circular.
The beneficial effects of the utility model are as follows:
The utility model is by arranging a plurality of circular shoulder holes with identical central in base interior, can cooperate multiple the circular aluminum section bar with diameter to use, by in the vertical sleeve pipe that is installed in the pedestal middle part jumper bar being set, connect centre drill at the jumper bar internal whorl, bullet by centre drill one end is realized the location to circular aluminum section bar central point, operating process simple and fast.
Description of drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the structural representation of jumper bar in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1 and Figure 2, the utility model comprises pedestal 1, has the shoulder hole with same center of circle 2 that diameter successively decreases step by step in the inside of pedestal 1, and shoulder hole 2 is circular, sleeve pipe 3 is vertically arranged at center at pedestal 1, have the through hole with pedestal 1 concentric in the sleeve pipe 3, device jumper bar 5 in through hole, the outer race shock mount 4 of jumper bar 5, as shown in Figure 3, have threaded mounting hole in the jumper bar 5, connect centre drill 501 in described threaded mounting hole internal thread, an end of centre drill 501 has bullet.
Specific works process of the present utility model is as follows:
Such as Fig. 1, shown in Figure 3, after selecting suitable shoulder hole according to the diameter of circular aluminum section bar, pedestal 1 is placed on the surface of circular aluminum section bar, then centre drill 501 is threaded with jumper bar 5, the through hole that will stretch into the jumper bar of centre drill 501 sleeve pipe 3 is inner, and operating personnel knock an end of jumper bar 5 by hammer or hammer, makes the Surface Contact of the bullet of centre drill 501 and circular aluminum section bar and forms centre bore, finish rear spring 4 effects jumper bar 5 is ejected, time saving and energy saving.
The utility model is by arranging a plurality of circular shoulder holes with identical central in base interior, can cooperate multiple the circular aluminum section bar with diameter to use, by in the vertical sleeve pipe that is installed in the pedestal middle part jumper bar being set, connect centre drill at the jumper bar internal whorl, bullet by centre drill one end is realized the location to circular aluminum section bar central point, operating process simple and fast.
Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, in the situation that without prejudice to basic structure of the present utility model, the utility model can be done any type of modification.
