Description

Technical Field

[0001] This invention relates to the field of metal processing technology, and in particular to a drilling apparatus for the production of speed reducers. Background Technology

[0002] A speed reducer is an independent component consisting of gear drives, worm drives, or gear-worm drives enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between the driving component and the working machine. According to the number of transmission stages, speed reducers can be divided into single-stage and multi-stage speed reducers; according to the shape of the gears, they can be divided into cylindrical gear reducers, bevel gear reducers, and bevel-cylindrical gear reducers; according to the transmission arrangement, they can be divided into open-type, split-type, and coaxial-type speed reducers.

[0003] A search revealed Chinese Patent Publication (Announcement) No. CN117817010A, which discloses a drilling device for processing a reducer housing. The technical solution includes an annular support frame and a sliding support frame fixedly disposed inside the annular support frame. The sliding support frame has multiple sliding cavities evenly distributed along the radial direction of the annular support frame. A drill bit clamping device is slidably disposed in each of the multiple sliding cavities. A drive mechanism for driving the drill bit clamping device to rotate is fixedly disposed on one side of the annular support frame.

[0004] The aforementioned patent has the following shortcomings: the drilling device can only meet the requirement of drilling holes on the top of the reducer housing during the drilling process, but it cannot meet the requirement of drilling holes in other parts of the reducer, which greatly reduces the practicality of the drilling device. Furthermore, the drilling device lacks corresponding cooling measures during the drilling process, resulting in excessively high drill rod temperature after prolonged drilling, thus affecting its service life. Summary of the Invention

Limit sliders are welded to the outer walls on both sides of the mounting top plate 3.

[0032] The size of the limiting slide groove is adapted to the size of the limiting slider. One end of the bottom of the mounting top plate 3 is connected to a hydraulic telescopic rod 4 by screws, and a limiting cap 5 is fixedly snapped onto the top outer wall of the limiting bracket 2. The top of the mounting top plate 3 is rotatably mounted with a back hole drill rod 6, a drilling screw 7, and a tapping rod 8 at equal distances. The top axis of the back hole drill rod 6, the drilling screw 7, and the tapping rod 8 are all connected to a first servo motor 9. The outer wall of the first servo motor 9 is provided with a protective cover 10.

[0033] The top outer wall of the processing base 1 is fixed with symmetrically distributed electric slide rails 13 along the width direction, and an electric slider 14 is slidably inserted into the inner wall of the electric slide rail 13. A rectangular connecting plate 15 is fixed on the top of the electric slider 14, and a enclosure cover 16 is welded to the top four outer walls of the rectangular connecting plate 15. An electric telescopic rod 24 is connected to one side outer wall of the first guide block 22 by screws.

[0034] Before drilling, the hole is reversed using a reverse drill rod 6, which can effectively improve the drilling accuracy and overall processing effect. A tapping rod 8 is designed to create threads on the inner wall after drilling, which can effectively meet different drilling needs and improve the practicality of the drilling device.

[0035] The rectangular fixing plate 23 has liquid guiding grooves 17 on both sides of the top of the rectangular fixing plate 23 along the inclined direction.

The outer wall of one side of the enclosure cover 16 is welded with a mounting base 18, and a second servo motor 19 is fixed on the mounting base 18 by screws. The output shaft of the second servo motor 19 is connected to a burr grinding column 20. The rectangular connecting plate 15 has a first guide rail 21 welded parallel to the length direction in the middle. A first guide block 22 is slidably inserted into the top of the first guide rail 21. The top outer wall of the first guide block 22 is welded with a rectangular fixing plate 23.

[0036] The inner wall of one side of the filter housing 38 is connected to a micro lift pump 42 via a pipe, and the output end of the micro lift pump 42 is fixed with an inlet pipe 43. The end of the inlet pipe 43 away from the micro lift pump 42 is connected to a connecting pipe 11, and the inner wall of one side of the connecting pipe 11 is connected to three equally spaced cooling spray pipes 12.

[0037] A rotating plate 25 is rotatably mounted on the top of the rectangular fixed plate 23, and a geared motor 26 is connected to one side of the rotating plate 25 via a coupling. A second guide rail 27 is welded to the outer walls of both sides of the rotating plate 25, and a second guide block 28 is slidably inserted into the outer wall of the middle part of the second guide rail 27. An adjusting plate 29 is fixed on the second guide block 28, and a linkage plate 30 is rotatably mounted between the two adjusting plates 29. A circular through hole is opened through the outer wall of the two adjusting plates 29, and a limit rod 31 is slidably inserted into the inner wall of the circular through hole.

[0038] When drilling holes in the reducer housing, the compression spring 32 and the arc-shaped locking block 35 work together to quickly adapt and lock the reducer housing with different inner wall sizes. The housing can also be rotated by the geared motor 26 after being locked, so as to meet the drilling requirements at different positions. The second servo motor 19 drives the burr grinding column 20 to rotate, which can quickly grind the burrs at the bottom after drilling, so as to avoid the burrs on the inner wall affecting subsequent use.

[0039] A cylindrical filter screen box 39 is snapped and fixed between the filter housing 38 and the sealing cover plate 37. An agitator blade 40 is rotatably installed at the axial center of the bottom inner wall of the cylindrical filter screen box 39.

The sealing cover plate 37 is fixed to the top of the filter housing 38.

[0041] When using this reducer for drilling, first assemble the device. After assembly, connect it to an external power source and test run it. Once the test run is normal, pour coolant into the filter housing 38. Then, use the electric telescopic rod 24 to extend and retract, moving the rectangular fixed plate 23 to the end of the second guide rail 27. First, use the servo cylinder 34 to push the impact block 33, causing the adjusting plate 29 to move closer together. This, in conjunction with the linkage plate 30, rotates the two arc-shaped locking blocks 35 closer together. Then, place the reducer motor housing to be drilled outside the two arc-shaped locking blocks 35, release the impact block 33, and compress the spring 3. 2. The two adjusting plates 29 will be reset and moved away from each other to achieve fixed support for the inner wall of the geared motor. After the geared motor housing is clamped and fixed, the electric slider 14 at the bottom slides to move the geared motor housing to the bottom of the reverse drilling rod 6. Then, the hydraulic telescopic rod 4 is retracted to drive the reverse drilling rod 6 to descend, thereby starting the first servo motor 9 to drive the reverse drilling rod 6 to rotate and perform hole enlargement treatment on the geared motor housing. After the hole enlargement treatment is completed, the electric telescopic rod 24 is used to drive the geared motor housing to move below the drilling screw 7. Then, the hydraulic telescopic rod 4 is retracted to drive the drilling screw 7 to rotate, thereby performing rapid drilling treatment on the geared motor housing.

[0042] Example 2, refer to Figure 1-5 A drilling device for producing a speed reducer includes a processing base 1. A limit bracket 2 is fixed to one side of the middle part of the processing base 1 by bolts. A mounting top plate 3 is slidably inserted into the middle part of the limit bracket 2. The inner wall of the middle part of the limit bracket 2 has symmetrically distributed limit grooves along the vertical direction. Limit sliders are welded to the outer walls on both sides of the mounting top plate 3.

[0043] The size of the limiting slide groove is adapted to the size of the limiting slider. One end of the bottom of the mounting top plate 3 is connected to a hydraulic telescopic rod 4 by screws, and a limiting cap 5 is fixedly snapped onto the top outer wall of the limiting bracket 2. The top of the mounting top plate 3 is rotatably mounted with a back hole drill rod 6, a drilling screw 7, and a tapping rod 8 at equal distances. The top axis of the back hole drill rod 6, the drilling screw 7, and the tapping rod 8 are all connected to a first servo motor 9.

[0044] The top outer wall of the processing base 1 is fixed with symmetrically distributed electric slide rails 13 along the width direction, and an electric slider 14 is slidably inserted into the inner wall of the electric slide rail 13.

The rectangular connecting plate 15 has a first guide rail 21 welded parallel to the length direction in the middle. A first guide block 22 is slidably inserted into the top of the first guide rail 21. The top outer wall of the first guide block 22 is welded with a rectangular fixing plate 23.

[0046] When drilling holes in the housing of the geared motor, the continuously sprayed coolant can reduce the frictional heat during the drilling process. The cooled waste liquid is treated by centrifugal force accelerated by the rotation of the stirring blade 40 to settle the metal waste. The supernatant is discharged, filtered, and then extracted again for secondary use. This can effectively reduce the waste of coolant and improve the utilization rate of resources.

[0047] The inner wall of one side of the filter housing 38 is connected to a micro lift pump 42 via a pipe, and the output end of the micro lift pump 42 is fixed with an inlet pipe 43. The end of the inlet pipe 43 away from the micro lift pump 42 is connected to a connecting pipe 11, and the inner wall of one side of the connecting pipe 11 is connected to three equally spaced cooling spray pipes 12.

[0048] A rotating plate 25 is rotatably mounted on the top of the rectangular fixed plate 23, and a geared motor 26 is connected to one side of the rotating plate 25 via a coupling. A second guide rail 27 is welded to the outer walls of both sides of the rotating plate 25, and a second guide block 28 is slidably inserted into the outer wall of the middle part of the second guide rail 27. An adjusting plate 29 is fixed on the second guide block 28, and a linkage plate 30 is rotatably mounted between the two adjusting plates 29. A circular through hole is opened through the outer wall of the two adjusting plates 29, and a limit rod 31 is slidably inserted into the inner wall of the circular through hole.

[0049] A cylindrical filter screen box 39 is snapped and fixed between the filter housing 38 and the sealing cover plate 37. An agitator blade 40 is rotatably installed at the axial center of the bottom inner wall of the cylindrical filter screen box 39. The cylindrical filter screen box 39 has a cylindrical shell mesh structure and is filled with activated carbon. The length of the cylindrical filter screen box 39 is adapted to the depth of the inner wall of the filter housing 38. A drive motor 41 is connected to the axial center of the bottom of the agitator blade 40, and a slag discharge pipe is connected to the bottom of one side inner wall of the cylindrical filter screen box 39.

[0050] Both adjustment plates 29 have arc-shaped locking blocks 35 welded to their outer walls, and anti-slip rubber pads are adhered to the outer walls of the arc-shaped locking blocks 35. A compression spring 32 is sleeved on the outer wall of the limiting rod 31, and the compression spring 32 is in a compressed state. An impact block 33 is welded to the outer wall of one of the adjustment plates 29. A servo cylinder 34 is provided on one side of the impact block 33. A liquid guiding pipe 36 is connected to the bottom inner wall of the liquid guiding trough 17, and the bottom of the liquid guiding pipe 36 is inserted into the sealing cover plate 37. The sealing cover plate 37 is fixed to the top of the filter housing 38.

[0051] When using the drilling device for production using this speed reducer, first assemble the device. After assembly, connect it to an external power source and test run it. After the test run is normal, pour coolant into the filter housing. Then, use the electric telescopic rod 24 to extend and retract, moving the rectangular fixed plate 23 to the end of the second guide rail 27. First, use the servo cylinder 34 to push the impact block 33, thereby moving the adjusting plate 29 closer together. This, in conjunction with the linkage plate 30, causes the two arc-shaped locking blocks 35 to move closer together. Then, place the geared motor housing to be drilled outside the two arc-shaped locking blocks 35, release the impact block 33, thereby compressing the spring 32. The two adjusting plates 29 will be reset and moved away from each other to achieve fixed support for the inner wall of the geared motor. After the geared motor housing is clamped and fixed, the electric slider 14 at the bottom slides to move the geared motor housing to the bottom of the reverse drilling rod 6. Then, the hydraulic telescopic rod 4 is retracted to drive the reverse drilling rod 6 to descend, thereby starting the first servo motor 9 to drive the reverse drilling rod 6 to rotate and perform hole enlargement treatment on the geared motor housing. After the hole enlargement treatment is completed, the electric telescopic rod 24 is used to drive the geared motor housing to move below the drilling screw 7. Then, the hydraulic telescopic rod 4 is retracted to drive the drilling screw 7 to rotate, thereby performing rapid drilling treatment on the geared motor housing.

[0052] After the housing of the geared motor is drilled, if other requirements are needed, simply adjust the geared motor to the bottom of the tapping rod 8, and then thread the inner wall after drilling. During the process, the micro lift pump 42 is used to pump the cooling liquid to the inner wall of the connecting pipe 11, which, together with the cooling spray pipe 12, can cool the drill rod. The heated waste liquid after cooling flows out from the bottom guide pipe 36 into the filter housing 38. The bottom drive motor 41 is started to drive the stirring blade 40 to rotate, and centrifugal force is used to accelerate the sedimentation of metal debris. The metal debris that settles to the bottom is discharged from the slag discharge pipe, while the top supernatant is filtered through the columnar filter screen box 39 and discharged for secondary use, thereby reducing the waste of resources.
