[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] See also Figures 1-14 The present invention provides a boring device for producing a wire-moving reducer, comprising a numerically controlled bed 1, wherein a fixing member 2 for fixing the wire-moving reducer is provided in the numerically controlled bed 1, and the wire-moving reducer is fixedly clamped by the fixing member 2. In this application, the fixing member 2 is conventional in the art and will not be described in detail. A boring drill bit 3 is provided above the fixing member 2;

[0040] It also includes a movable plate 4, in which a first inclined plate 5 and a second inclined plate 6 are symmetrically distributed. The CNC bed 1 is provided with a translation plate 7. An electric guide rail can be provided on the CNC bed 1, which is connected and fixed to the translation plate 7 through the electric guide rail, so that the translation plate 7 and other structures located on the translation plate 7 can be moved and adjusted to facilitate the adjustment of the position of the boring drill bit 3 and the switching of the boring position of the counter-wire reduction box. The translation plate 7 is rotatably connected to a rotating disk 9 that rotates simultaneously with the first inclined plate 5 and the second inclined plate 6 through a power member 8.

[0041] A tool rod 10 connected to the boring drill bit 3 is fixedly connected to the middle of the first inclined plate 5, and a friction roller 11 is fixedly connected to the middle of the second inclined plate 6. The tool rod 10 passes through the middle of the friction roller 11.

[0042] The rotating disc 9 is rotated by the power member 8, and the rotating disc 9 drives the inclined first inclined plate 5 and the second inclined plate 6 to rotate synchronously. The rotation directions of the first inclined plate 5 and the second inclined plate 6 are different, so that the boring of the tool rod 10 entering the wire transfer reduction box and the grinding of the friction roller 11 are carried out synchronously, and the boring directions of the tool rod 10 and the grinding directions of the friction roller 11 are opposite, which is convenient for fine boring. After the tool rod 10 is bored, the hole opening rotation direction and the burr distribution direction of the inner wall of the hole are opposite to the grinding direction of the friction roller 11. The friction roller 11 set to rotate in the opposite direction is conducive to fine boring of the hole wall;

[0043] At the same time, the cutter bar 10 and the friction roller 11 reciprocate axially with each other, that is, the first inclined plate 5 drives the cutter bar 10, and the second inclined plate 6 drives the friction roller 11 to make a reciprocating movement of approaching and moving away, so that the boring of the cutter bar 10 and the grinding of the friction roller 11 are staggered, which improves the efficiency of fine boring on the one hand and facilitates slag extraction on the other hand;

[0044] The inside of the tool rod 10 is hollow, and the top of the movable plate 4 is fixedly connected to a sleeve 24 that is sleeved on the top of the tool rod 10. The CNC bed 1 is connected to the sleeve 24 through a hose of a vacuum device. The vacuum device allows the debris generated by the boring drill bit 3 to pass through the slag discharge groove, the storage groove 18, the middle part of the tool rod 10, and the sleeve 24 on the boring drill bit 3 in turn, and finally enter the storage box in the vacuum device.

[0045] A telescopic power mechanism 12 (a cylinder device or an electric telescopic rod 15 device) is fixedly connected to the translation plate 7. The telescopic power mechanism 12 drives the movable plate 4 to move downward, thereby driving the boring drill bit 3, the tool rod 10, the friction roller 11 and the structure inside the movable plate 4 to move downward, thereby completing the boring footage;

[0046] The telescopic end of the telescopic power mechanism 12 is connected and fixed to the movable plate 4 with a U-shaped structure, the output shaft of the power part 8 passes through the movable plate 4 and is connected and fixed to the rotating disk 9, the outer shell of the power part 8 (motor) is connected and fixed to the middle part of the movable plate 4, and the output shaft of the power part 8 rotates to drive the rotating disk 9 to rotate in its original position in the movable plate 4.

[0047] When the rotating disk 9 rotates, since a plurality of grooves 13 are provided on the edge of the rotating disk 9, the switching of the grooves 13 and the engagement of the fixed posts 14 connected to the edges of the first inclined plate 5 and the second inclined plate 6, in conjunction with the pressing action of the telescopic rod 15, make the grooves 13 tightly mesh with the posts 14, thereby causing the rotating disk 9 to drive the first inclined plate 5 and the second inclined plate 6 to rotate, that is, drive the knife bar 10 and the friction roller 11 to rotate on the movable plate 4;

[0048] In the present application, a telescopic rod 15 is fixedly connected to the movable plate 4, and an elastic compression part is provided inside the telescopic rod 15. Through the compressive elastic force of the elastic compression part, the size of the compressive elastic force in the present application is based on actual conditions, and high-strength alloy steel (such as 60Si2MnA) is selected to make the end of the telescopic rod 15 press and fit with the inclined first inclined plate 5 and the second inclined plate 6.

[0049] Among them, a limiting ball 16 is movably embedded in the end of the telescopic rod 15, and a pressure plate 17 that presses against the first inclined plate 5 and the second inclined plate 6 is fixedly connected to the limiting ball 16, so as to ensure that the pressure plate 17 rotates with the rotating first inclined plate 5 and the second inclined plate 6 to adjust the angle, while the pressure plate 17 tightly presses the first inclined plate 5 and the second inclined plate 6, ensuring that the groove 13 is always tightly engaged with the clamping column 14, that is, ensuring that the rotating disk 9 is always engaged with the first inclined plate 5 and the second inclined plate 6.

[0050] Description of the relative reciprocating motion of the cutter bar 10 and the friction roller 11 in the axial direction:

[0051] The cutter bar 10 and the friction roller 11 both pass through the movable plate 4. The rotary disk 9 rotates, driving the first inclined plate 5 and the cutter bar 10 to rotate clockwise. Since the first inclined plate 5 and the second inclined plate 6 are always engaged with the rotary disk 9, when the first inclined plate 5, the cutter bar 10 and the boring drill bit 3 move upward at the same time, the second inclined plate 6 and the friction roller 11 rotate counterclockwise and move downward.

[0052] When the first inclined plate 5, the cutter bar 10 and the boring drill bit 3 move downward simultaneously, the second inclined plate 6 and the friction roller 11 move upward;

[0053] As a result, the cutter bar 10 and the friction roller 11 are moved back and forth, so that the boring of the cutter bar 10 and the grinding of the friction roller 11 are carried out synchronously and staggered, which is convenient for timely cleaning of debris and avoids the low efficiency caused by the grinding process after the boring of the cutter bar 10 is completed.

[0054] Among them, after the tool rod 10 boring the hole, the hole opening rotation direction and burr distribution direction of the inner wall of the hole are both clockwise, while the friction roller 11 rotates counterclockwise, effectively eliminating the traces of the hole wall and ensuring the smoothness of the hole wall;

[0055] When the knife bar 10 and the friction roller 11 make a reciprocating approach and distance movement, a receiving groove 18 is opened at the bottom of the knife bar 10 and communicated with the interior of the knife bar 10, a rotating ring 19 is rotatably connected to the bottom of the friction roller 11, and a plurality of dredging plates 20 are rotatably connected to the bottom surface of the rotating ring 19. A limiting groove 21 is opened on the outer surface of the knife bar 10 and communicated with the receiving groove 18, and the dredging plates 20 slide in the limiting groove 21;

[0056] The friction roller 11 drives the rotating ring 19 to move up and down along the cutter bar 10, and the rotating ring 19 rotates adaptively to ensure that the dredging plate 20 moves up and down along the limiting groove 21 and the receiving groove 18. The dredging plate 20 is inserted into the receiving groove 18 to crush and dredge the debris accumulated in the receiving groove 18 to prevent the debris from clogging the receiving groove 18. The exhaust device is used to help collect the debris in the boring process in time.

[0057] Among them, the bottom of the dredging plates 20 on both sides is fixedly connected to an elastic plate 22, and the outer surface of the knife rod 10 is fixedly connected to the position near the bottom of the receiving groove 18, and the top plate 23 and the elastic plate 22 (elastic metal plate) are at an inclined angle that matches each other; when the dredging plates 20 are inserted into the receiving groove 18, the dredging plates 20 drive the elastic plates 22 to move close to the top plate 23, and when the elastic plates 22 press and contact the top plate 23, under the pressure of the inclined angle, the elastic plates 22 are tilted and rotated, and the two dredging plates 20 on the outside are rotated away from each other, thereby rotating and squeezing the debris in the receiving groove 18 to prevent the debris from clogging the receiving groove 18;

[0058] When the dredging plate 20 moves upward, the elastic plate 22 moves away from the top plate 23 , and under the action of the intersection of the receiving groove 18 and the limiting groove 21 (an arc-shaped surface), the two dredging plates 20 are moved closer to each other and received into the limiting groove 21 .

[0059] A floating boring blade, multiple groups of movable blades 25 located in the chip removal groove on the outer surface of the boring drill bit 3, each group of movable blades 25 is fixedly connected with a plug-in rod 26, and the plug-in rod 26 is movably plugged into the boring drill bit 3;

[0060] When the boring drill bit 3 rotates and bores along the wire-moving reduction gearbox, the chips move from the chip discharge groove, and the movable blade 25 rotates synchronously with the boring drill bit 3. At the same time, the movable blade 25 reciprocates horizontally relative to the boring drill bit 3, thereby crushing the chips that pass through the chip discharge groove again, thereby facilitating the recovery of the fixed chips in conjunction with the exhaust device;

[0061] Among them, when the connecting rod 26 moves along the boring drill bit 3, the movable blade 25 moves a small distance in the horizontal direction relative to the boring drill bit 3, thereby automatically adjusting the movable range of the movable blade 25, which is more conducive to slag removal processing. However, the movable range of the movable blade 25 is limited and will not exceed the circumferential range of the boring drill bit 3 (that is, the movable blade 25 will not touch the inner wall of the hole of the wire moving reducer).
