Description
Technical field
The utility model relates to a kind of servicing unit for steel construction processing, specifically, relates to a kind of servicing unit for round steel boring.
Background technology
In steel construction processing and manufacturing process, usually need the round steel in the member is carried out perforate processing.During boring, because steel bores and the contact-making surface of round steel is not the plane, and round steel skids in boring procedure easily, can make troubles to processing, and probably produce error, or even member is cancelled, can not guarantee the correctness of processing and the quality of manufacturing, if the employing casting technique, the time, longer expense was larger, and was difficult to guarantee to produce in batch.
The utility model content
To be solved in the utility model is existing round steel Drilling operation operating difficulties, and workmanship is low, and the technical problem that precision is not accurate enough provides a kind of round steel drilling aid, and features simple structure is small and exquisite, and process operation is convenient, uses safety and stability, can reuse.
In order to solve the problems of the technologies described above, the utility model is achieved by following technical scheme:
A kind of round steel drilling aid, comprise base plate, the centre of described base plate is provided with the angle steel base of opening upwards, the intermediate angle of described angle steel base is stupefied to be welded on the center line of described floor length direction, one end of described angle steel base is provided with the baffle plate of bottom welding on described base plate, the Si Jiaochu of described base plate is provided with gripper shoe, described gripper shoe welded top has the top board that is parallel to described base plate, described top board center is welded with hold-down nut, described hold-down nut is equipped with the puller bolt that passes described top board, described top board surface is provided be used to the circular hole that passes drill bit at the center line of length direction, is welded with the tubular cylinder that exposes described top board surface on the described circular hole.
The beneficial effects of the utility model are:
The utility model structure is small and exquisite, make simple, easy to operate, prevent from skidding, processing is quick and precisely used safety and stability, end product quality is reliable, the round steel that is particularly suitable for pair radius and is arbitrary size between the 25-60mm is fixed perforate, and has the function that can reuse, and is conducive to the large batch of perforate processing of carrying out.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the front view of Fig. 1;
Fig. 3 is the left view of Fig. 1;
Fig. 4 is use state diagram of the present utility model.
Among the figure: 1: base plate, 2: gripper shoe, 3: baffle plate, 4: top board, 5: puller bolt, 6: hold-down nut, 7: tubular cylinder, 8: angle steel base, 9: the round steel member.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail:
As shown in Figure 1 to Figure 3, present embodiment has disclosed a kind of round steel drilling aid, comprises a base plate 1 of being made by the general steel plate of 500*170*20.Be provided with an angle steel base 8 that made by the angle steel of 100*100*24, that length is 400mm at its length direction in the middle of the base plate 1, the opening upwards of angle steel base 8, intermediate angle is stupefied to be fixedly welded on the center line of base plate 1 length direction.Afterbody one end of angle steel base 8 is provided with a baffle plate 3 that is of a size of 150*85*20, and the bottom welding of baffle plate 3 is fixed on the base plate 1.
The Si Jiaochu of base plate 1 is provided with 2, four gripper shoes 2 of four gripper shoes and is made by the little steel plate of the same 105*35*20 of being of a size of.The welded top of four gripper shoes 2 has a top board 4, and top board 4 be arranged in parallel with base plate 1, and is also made by the general steel plate of 500*170*20.
A small sircle hole is offered in the center of top board 4, and the welded top of small sircle hole has a hold-down nut 6, a stay bolt is installed as puller bolt 5 on the hold-down nut 6, and puller bolt 5 passes successively hold-down nut 6 and top board 4 and reaches under the top board 4.
Offer several circular holes in suitable position on the center line of top board 4 length directions, circular hole can guarantee that drill bit frees in and out therein.Offer and be welded with little tubular cylinder 7 on the circular hole, tubular cylinder 7 exposes top board 4 surfaces.
As shown in Figure 4, during use, will need first the round steel member 9 of perforate to be placed on angle steel base 8, round steel member 9 ends are supported on baffle plate 3,3 pairs of round steel members 9 of angle steel base 8 and baffle plate radially, axial location.Then screw puller bolt 5, it is contacted with round steel member 9, play the effect of skidding of preventing.The circular hole of tubular cylinder 7 bottoms be opened in round steel member 9 need position of opening directly over top board 4 places, drill bit is put in the circular hole by tubular cylinder 7, just can carry out accurately Drilling operation operation to round steel member 9, very convenient quick, can be good at guaranteeing the degree of accuracy and the required precision of processing.
Although the above is described preferred embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, can also make the concrete conversion of a lot of forms, these all belong within the protection domain of the present utility model.
