On the drill bit seat, it is convenient to install and disassemble, and also includes the machine tool base, which is connected with the fixture for fixing the round pipe through the chute 11, and the outer side of the installation sleeve 1 is symmetrically fixed with two horizontal cantilevers 2, the cantilever 2 The bottom of the shock absorber 3 and the compression rod 4 are respectively hingedly connected through the pin shaft, and the lower end of the shock absorber 3 is hingedly connected with the lower part of the pressure rod 4 through the pin shaft. A guide mechanism is arranged between the upper ends of the bars 15, and the bottom of the slanting bars 15 is slidably connected to the machine bed, and the middle part of the slanting bars 15 is correspondingly connected with the lower end of the pressing bar 4.

In this embodiment, the lower end of the inclined bar 15 is fixed with a lower straight section 17, and the lower straight section 17 is slidingly connected with the chute one 11, and the stopper two 10 corresponding to the lower straight section 17 is fixed on the machine bed. Straight section 17 connects stopper two 10 by spring two 9.

In this embodiment, a chute 2 16 is provided on the upper side of the slanting bar 15, and the sliding block 6 is slidably connected through the chute 2 16, and a stopper 8 is fixed at the connection between the slanting bar 15 and the lower straight section 17, and the sliding block 6 is connected with the stopper 8 through the spring one 7, and the slot 5 corresponding to the pressure bar 4 is fixed on the slide block 6. When the pressure bar 4 is not in contact with the slot 5, the slot 5 is located Right below the depression bar 4.

In this embodiment, the cross-section of the connection between the lower straight section 17 and the first chute 11 is a dovetail structure that cooperates with each other. Similarly, the cross-section of the connection between the slider 6 and the second chute 16 is also a cross-section that cooperates with each other. dovetail structure.

Guide rods 13 are respectively fixed on both sides of the guide sleeve 12, and the guide rods 13 are slidably connected to the corresponding The guide hole on the upper straight section 14, the guide rod 13 is a polygonal rod structure, and a damping ring is connected between the guide rod 13 and the upper straight section 14.

The principle and advantages of the utility model: when the guide device for the high-precision drilling machine is used for drilling the round pipe, the operation is as follows:

The initial shape is too low, the pressure rod 4 is located above the oblique rod 15 and does not contact the slot 5, the round pipe is placed between the two oblique rods 15, and the two oblique rods 15 need to be forced when placing the round pipe. Compress spring 2 9 toward both sides along chute 11, so that spring 2 9 obtains a restoring force. After putting the round pipe between the inclined bars 15, adjust the position so that the drilling position is located directly below the guide sleeve 12. Loosen the oblique rod 15, under the action of the restoring force obtained by the spring 2 11, the oblique rod 15 has a pre-tightening force on the round pipe, so as to maintain the fixed clamping of the round pipe;

After the installation of the round pipe fittings is completed, start the machine tool and when the drill head moves the drill down, it will synchronously drive the installation sleeve 1 to move down, and the downward movement of the installation sleeve 1 will drive the pressure rod 4 and the shock absorber rod 3 to move down synchronously, and the lower end of the pressure rod 4 will gradually move down. Close to the slot 5, as the drill bit continues to move down, the pressure rod 4 contacts and cooperates with the slot 5, and as the drill bit moves down, the pressure rod 4 exerts a force on the slider 6, so that the slider 6 moves along the two sides of the chute. 16 moves down, and the downward movement of the slider 6 exerts a force on the inclined rod 15 on the one hand, so that the two inclined rods 15 can clamp and fix the round pipe more stably, avoiding the shaking of the round pipe when drilling, on the other hand, the sliding The downward movement of the block 6 compresses the spring one 7 so that the spring one 7 obtains a restoring force;

After the pressure rod 4 is in contact with the slot 5, a displacement effect is generated to cause the pressure rod 4 to rotate around the axis, and the rotation of the pressure rod 4 exerts pressure on the shock absorber rod 3 so that the shock absorber rod 3 is compressed by force, and the effect of the shock absorber rod 3 is played. To buffer the vibration generated during drilling, maintain the stability of the drill bit during drilling, and improve the machining accuracy, the drill bit passes through the guide sleeve 12 pairs of round pipes during the downward movement to drill holes;

After the drilling is completed, the drill bit seat drives the drill bit upward, and the upward movement of the drill bit simultaneously drives the installation sleeve 1 upward, and the upward movement of the installation sleeve 1 drives the pressure rod 4 and the shock absorber rod 3 to move upward synchronously, and the lower end of the pressure rod 4 gradually decreases. The pressure on the slot 5 is small, and as the drill bit continues to move up, the pressure rod 4 is separated from the slot 5, and the pressure rod 4 does not exert force on the slider 6, and the restoring force obtained by the slider 6 in the spring 7 Under the action, move up and reset along the chute 2 16. After the pressure rod 4 is separated from the slot 5, the shock absorber rod 3 resets to drive the pressure rod 4 to reset, and then applies force to the two oblique rods 15, and the two oblique rods 15 separate, and take off the finished round pipe fitting from the machine bed.

Finally, it should be noted that: the above is only a preferred embodiment of the utility model, and is not intended to limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art , it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
