Abstract
The utility model discloses an eccentric accurate adjustment deep blind hole precision boring cutter holder device, which comprises a right angle long boring cutter holder, an eccentric location connecting sleeve, an anti-rotate screw and a long cutter holder handle, wherein the eccentric location connecting sleeve is sleeved on one end of the right angle long boring cutter holder, and the long cutter holder handle is fixedly connected with the right angle long boring cutter holder and the eccentric location connecting sleeve through the anti-rotate screw. The eccentric accurate adjustment deep blind hole precision boring cutter holder device can meet the process and the use of deep blind holes of steel box castings, has convenient and simple operation, and can effectively increase the process efficiency.
Description
Technical field
The utility model relates to a kind of Machining Technology, particularly relates to the dark blind hole tool-bar for accurately boring of a kind of eccentric accurate adjustment device.
Background technology
Commonsense method to the dark blind hole processing of steel box casting is to adopt a knife bar, but the cutter head that a coarse adjustment is set on the knife bar is processed, this knife bar can not be estimated workpiece, or change finishing step over to, need to regulate cutter head, or changing knife rod, proofread and correct again, very inconvenient, be difficult to reach the required required precision of workpiece working position.
The utility model content
The technical problems to be solved in the utility model is in order to overcome the defective of prior art, the dark blind hole tool-bar for accurately boring of a kind of eccentric accurate adjustment device is provided, its processing that can satisfy the dark blind hole of steel box casting is used, and easy to operate and simple and direct, can effectively improve working (machining) efficiency.
The utility model solves above-mentioned technical problem by following technical proposals: the dark blind hole tool-bar for accurately boring of a kind of eccentric accurate adjustment device, it is characterized in that, it comprises the long boring cutter bar in right angle, off-centre be located by connecting cover, anti-turn screw and long holder, off-centre is located by connecting and is enclosed within an end of the long boring cutter bar in right angle, and long holder is located by connecting to overlap by the long boring cutter bar in anti-turn screw and right angle, off-centre and fixedlys connected.
Preferably, the dark blind hole tool-bar for accurately boring of described eccentric accurate adjustment device also comprises a cutter head, and cutter head is fixedlyed connected with the other end of the long boring cutter bar in right angle by a coarse adjustment screw.
Positive progressive effect of the present utility model is:
A. the design off-centre cover that is located by connecting between the long boring cutter bar of stock handle of a knife and right angle, eccentric throw is 1mm, the off-centre cover end face that is located by connecting is provided with scale, accurately adjusting.
B. fastening after the long boring cutter bar in right angle is adjusted to the right place with anti-turn screw, can enter machining state.
C. easy to adjust, as long as unclamp anti-turn screw, rotation off-centre is located by connecting to overlap to finely tune and gets final product, and offers convenience to operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1, the dark blind hole tool-bar for accurately boring of the eccentric accurate adjustment of the utility model device comprise the long boring cutter bar 1 in right angle, off-centre be located by connecting overlap 2, anti-turn screw 3 and long holder 4, the off-centre end that cover 2 is enclosed within the long boring cutter bar 1 in right angle that is located by connecting, long holder 42 is fixedlyed connected by the long boring cutter bar 1 at least one anti-turn screw 3 and right angle, the off-centre cover that is located by connecting, and satisfies the rigidity requirement of whole tool-bar for accurately boring like this; And scale is set at off-centre cover 2 the outer disk that is located by connecting, for regulating finishing size.
In addition, the dark blind hole tool-bar for accurately boring of eccentric accurate adjustment device also can comprise a cutter head 5, and cutter head 5 is fixedlyed connected with the other end of the long boring cutter bar 1 in right angle by a coarse adjustment screw 6.
During fine finishining, unclamp anti-turn screw 3, rotating eccentricity is located by connecting and overlaps 2, the accurate cutter head processing dimension of adjusting, and again that anti-turn screw 3 is fastening, whole process is once finished.
The utility model is when the dark blind hole of processing steel box casting, carry out roughing earlier, when fine finishining, adjust the off-centre cover (generally can be accurate to 0.02mm) that is located by connecting then and carry out fine finishining, utilize the special angle of cutter head to carry out the baseplane processing of dark blind hole again, reach the required requirement on machining accuracy of workpiece.
Though more than described the specific embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these embodiments.Therefore, protection domain of the present utility model is limited by appended claims.
