Abstract
The utility model discloses an adjustable fine boring head. Adjustment screw sleeves are arranged in four large screw holes which are uniformly distributed in a boring head body and are fixed by locking nuts; spherical washers are arranged on the concave spherical surfaces of the adjustment screw sleeves; the upper end surfaces of the spherical washers are pressed against the lower side of an engine base; a cylinder on the upper side of the boring head body is arranged in a hole on the lower side of the engine base; long bolts penetrate through the adjustment screw sleeves and the spherical washers to fix the boring head body on the engine seat; the rotating axis of a boring head main shaft is parallel to the feed motion direction of the boring head; the nuts are arranged on short bolts; studs of the short bolts are arranged in four small screw holes which are uniformly distributed in a circular disc on the upper side of the boring head body; the upper end surfaces of the studs of the short bolts are pressed against the lower side of the engine base; and the four small screw holes uniformly distributed in the circular disc and the four large screw holes are formed on the same circle at equal intervals. The adjustable fine boring head is reasonably positioned, is easy to operate, and can quickly adjust the parallelism between the rotating axis of the boring head main shaft and the feed motion direction of the boring head to be less than the accuracy required by machined parts.
Description
Affiliated technical field
This practical sexual type relates to mechanical processing technique equipment, especially scalable fine boring head.
Background technology
Technical staff of the same trade knows that the rotation of the main shaft of boring machine and the parallelism error of direction of feed are one of main precision parameters of this boring machine.When processing is in diverse location and requires two coaxial holes, not that the boring cutter that is used in same position on the boring spindle boring bar processes this two holes, their axiality will have error.Valve seat orifice and valve guide bushing installing hole like the heavy duty cylinder head.The valve seat orifice that diameter 90 millimeters long are 22 millimeters is apart from the conduit installing hole of 80 millimeters of diameter 28 millimeters long more than 120 millimeter of distance up and down, with the boring cutter processing that is installed in diverse location on the boring spindle boring bar.Originally the axiality of finding two holes is defective, and reason is exactly that the rotation and the direction of feed of main shaft of boring machine is not parallel.
Summary of the invention
The purpose of this practical sexual type is the defective that overcomes prior art, and a kind of scalable fine boring head is provided, can be easily that boring head main axis rotation axis is parallel with the adjustment of the boring head feed direction of motion.
The purpose of this practical sexual type realizes as follows: the adjustment swivel nut is contained in four big screws that are uniformly distributed with on the disk of boring head body top to be fixed with locking nut; Spheric washer is contained on the concave spherical surface of the adjustment swivel nut identical with the spherical radius of spheric washer; The upper surface of spheric washer withstood on support following; The cylinder of boring head body top is contained in the following hole of support; Stay bolt passes the adjustment swivel nut, spheric washer is fixed on the boring head body on the support, and the rotation of boring head main shaft is parallel with the boring head feed direction of motion, and nut is contained on the lag bolt; The double-screw bolt of lag bolt is contained in four little screws that are uniformly distributed with on the disk of boring head body top, the double-screw bolt upper surface of lag bolt withstand on support below.
The position of the position of four little screws that are uniformly distributed with on the disk and big screw on same circle and at interval evenly.
The advantage of this scalable fine boring head is: the location rationally, and is simple to operate, can be adjusted in the precision of processing parts needs quickly the depth of parallelism of the rotation of boring head main shaft and the boring head feed direction of motion.
Description of drawings
Below in conjunction with accompanying drawing this practical sexual type is further described.
Accompanying drawing is the installation diagram of the scalable fine boring head of T716 diamond fine boring machine.Fig. 1 is the cutaway view of Fig. 2 along B-B, and Fig. 2 is the cutaway view along the A-A of Fig. 1.
1. lag bolts among the figure, 2. boring head body, 3. support, 4. locking nut, 5. stay bolt, 6. spheric washer, 7. adjustment swivel nut, 8. main shaft.
The specific embodiment
In installation diagram, the scalable fine boring head of boring machine comprises lag bolt (1), boring head body (2), support (3), locking nut (4), stay bolt (5), spheric washer (6), adjustment swivel nut (7) and main shaft (8); Boring head is following connection the through disk with the boring machine support (3) of boring head body (2) top.The boring head syndeton of design is that four adjustable strong points that are uniformly distributed with are installed on the disk of boring head body (2) top, so that regulate the position of the rotation of boring head main shaft (8).Adjustment swivel nut (7) is contained in uses locking nut (4) fixing as required in four big screws that are uniformly distributed with on the disk of boring head body (2) top, prevent to become flexible; Contact well with the disk of boring head body (2) top in order to adjust swivel nut (7); Spheric washer (6) is contained on the concave spherical surface of the adjustment swivel nut (7) identical with the spherical radius of spheric washer (6); The upper surface of spheric washer (6) withstood on support (3) following; The cylinder of boring head body (2) top is contained in the following hole of support (3), and stay bolt (5) passes adjustment swivel nut (7), spheric washer (6) is fixed on boring head body (2) on the support (3); Rotating adjustment swivel nut (7) as required just can guarantee the rotation of boring head main shaft (8) parallel with the adjustment of the boring head feed direction of motion; For the disk that increases boring head body (2) top the following rigidity that is connected, increase by 4 supports with lag bolt (1) with boring machine support (3); Nut is contained on the lag bolt, and the double-screw bolt of lag bolt (1) is contained in four little screws that are uniformly distributed with on the disk of boring head body (2) top, and the double-screw bolt upper surface of lag bolt (1) withstands on below the support (3).The position of the position of four little screws that are uniformly distributed with on the disk and big screw on same circle and at interval evenly, can make stressed evenly.
Claims (2)
1. scalable fine boring head; Comprise lag bolt, boring head body, support, locking nut, stay bolt, spheric washer, adjustment swivel nut and main shaft; It is characterized in that: the adjustment swivel nut is contained in four big screws that are uniformly distributed with on the disk of boring head body top to be fixed with locking nut, and spheric washer is contained on the concave spherical surface of the adjustment swivel nut identical with the spherical radius of spheric washer, and the upper surface of spheric washer withstood on support following; The cylinder of boring head body top is contained in the following hole of support; Stay bolt passes the adjustment swivel nut, spheric washer is fixed on the boring head body on the support, and the rotation of boring head main shaft is parallel with the boring head feed direction of motion, and nut is contained on the lag bolt; The double-screw bolt of lag bolt is contained in four little screws that are uniformly distributed with on the disk of boring head body top, the double-screw bolt upper surface of lag bolt withstand on support below.
