Abstract
The utility model relates to a floating boring cutter for processing an inner seam allowance and belongs to the field of machining. The floating boring cutter comprises a fixing shaft, a turning tool, a sliding pin, a spring and a fastening screw, wherein a radial blind hole is processed in the proximal end of the fixing shaft; a round handle is in sliding fit with the radial blind hole; a mounting hole perpendicular to the shaft direction is processed in the round handle; a sliding slot is designed in the bottom surface of the fixing shaft; the sliding pin is mounted in the mounting hole in the round handle of the turning tool through the sliding slot after the turning tool is mounted in the radial blind hole; the fastening screw is mounted on a point in the same diameter as the sliding slot; one end of the spring is fixed by the fastening screw, and the other end of the spring is connected with the sliding pin. Through the adoption of the structure that the fastening screw is connected with the sliding pin by the spring, the boring cutter has floating performance (i.e. telescopic performance); a rotary table rotates, a cutting edge of the turning tool cuts a part to be processed rotationally, the processing of the inner seam allowance can be completed. The floating boring cutter has the advantages that the structure is simple, the operation is convenient, and the processing efficiency of the inner seam allowance is greatly improved. Therefore, the floating boring cutter has higher popularization and application values.
Description
Technical field
The invention belongs to field of machining, particularly a kind of for processing the floating boring tool of inner stopper.
Background technology
Seam is the structure for centering, connection.One is male half coupling (being male half coupling), and another is recessed seam (being inner stopper).Both occur in pairs.Male half coupling is by the short cylindrical and the end face that protrude, formation.Recessed seam, consist of short hole and end face.In prior art, in processing during inner stopper, repeatedly mobile boring cutter, clamping, and will be to the boring cutter centering, and to movement, clamping, the centering of boring cutter, not only operation is loaded down with trivial details, complicated operation, inefficiency, not only time-consuming, take a lot of work, and the positional precision required is not easy to guarantee.
The utility model content
Numerous and diverse, the ineffective technical problem of operation when solving in above-mentioned prior art the processing inner stopper, it is a kind of simple in structure that the utility model provides, and makes easily, easy to operate for processing the floating boring tool of internal orifice.
For processing the floating boring tool of inner stopper, by fixed axis, lathe tool, sliding pin, spring and hold-down screw, formed, it is characterized in that, at the fixed axis proximal head, place is processed with radial blind holes, and lathe tool is arranged in radial blind holes by circular handle; Circular handle and radial blind holes are slidably matched, and the direction perpendicular to axle on circular handle is processed with installing hole; Being designed with chute, this chute and radial blind holes on the bottom surface of fixed axis is positioned on same sagittal plane; Lathe tool is packed into after radial blind holes, and sliding pin is seen through in the installing hole that chute is arranged on the circular handle of lathe tool, and sliding pin can be slided along chute, and the lathe tool cutting edge is towards the face at inner stopper place; With the same diameter of chute a bit on hold-down screw is installed, it fixes an end of spring, the other end of spring is connected with sliding pin.
The utility model utilizes spring that hold-down screw is connected with sliding pin, makes boring cutter have unsteady (i.e. flexible performance), the turntable rotation, and lathe tool cutting edge rotary cutting part to be processed, can complete the processing to inner stopper.Simple in structure, easy to operate, can greatly improve the operating efficiency of processing inner stopper, there is higher application value.
The accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 floating boring tool structure chart;
1. fixed axis 2. lathe tool 3. sliding pin 4. chute 5. spring 6. hold-down screw 7. inner stoppers in figure.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described as follows:
For processing the floating boring tool of inner stopper, by fixed axis 1, lathe tool 2, sliding pin 3, spring 5 and hold-down screw 6, formed, it is characterized in that, at fixed axis, 1 proximal head place is processed with radial blind holes, and lathe tool 2 is arranged in radial blind holes by circular handle; Circular handle and radial blind holes are slidably matched, and the direction perpendicular to axle on circular handle is processed with installing hole; Being designed with chute 4, this chute 4 and radial blind holes on the bottom surface of fixed axis 1 is positioned on same sagittal plane; Lathe tool 2 is packed into after radial blind holes, and sliding pin 3 is seen through in the installing hole that chute 4 is arranged on the circular handle of lathe tool, and sliding pin 3 can be slided along chute 4, and lathe tool 2 cutting edges are towards the face at inner stopper 7 places; With chute 4 same diameters a bit on hold-down screw 6 is installed, it fixes an end of spring 5, the other end of spring 5 is connected with sliding pin 3.When lathe starts, the turntable rotation of fixed axis 1 has been installed, fixed axis 1 drives lathe tool 2 rotations that are installed on it, lathe tool 2 is subject to centrifugal force to drive sliding pin 3 along chute 4 slips, sliding pin 3 slides into after the end of chute 4 turntable to be continued rotation and keeps centrifugal force, and the cutting edge of lathe tool 2 starts to carry out machining at the face at inner stopper 7 places.After inner stopper 7 machines, turntable drives after fixed axis 1 leaves cutting face and stops the rotation, and, under the effect of the pulling force of spring 5, sliding pin 3 drives the end retraction home position of lathe tools 2 from chute 4, the lathe tool original position of also retracting.
For making the flexible more flexible of lathe tool, floating boring tool also comprises adjustment block and mounting screw, described adjustment block and chute 4 are complementary, can be placed in chute 4, being fixedly mounted on by screw in chute 4 near chute 4 end places, when lathe tool 2 is subject to centrifugal force, drive sliding pin 3 and overcome spring 5 resistances, but adjusted piece can not continue to slide after limiting the position that slides into the adjustment block place again, and the scalable quantitative change of lathe tool is little, and the radius of the inner stopper 7 of processing also diminishes thereupon.Only need to change adjustment block during but inner stopper that diameter is different coaxial in processing and can realize the processing to the inner stopper of different radii, can greatly increase work efficiency.
Protection domain of the present utility model is not limited only to the disclosed technical scheme of specific embodiment part; utilize chute and the sliding pin that is arranged on the lathe tool handle to match, make boring cutter can float (stretching), and then all technical schemes that can process inner stopper all fall into protection domain of the present utility model.
