However, when drilling threaded pilot holes for the clutch, some of these holes may contain metal shavings, which can easily cause thread defects during tapping. To address these shortcomings, we propose a clutch housing drilling device. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Please see Figure 1-5This utility model provides a technical solution: a clutch housing drilling device, including a tool holder 10 mounted on the spindle of a vertical machining center, and a tooling plate 11 fixed to the worktable of the vertical machining center by bolts. The tooling plate 11 integrates a servo-driven rotatable worktable 20 and a chip blowing and oil injection composite mechanism. The tool holder 10 can be equipped with a drill bit and a tap. The tool holder 10 is mounted on the spindle of the vertical machining center, and the spindle rotation drives the tool to complete drilling and tapping. The tooling plate 11 is fixed to the rotatable worktable 20 by bolts. The integrated rotatable worktable 20 can achieve 360° free rotation, which is convenient for multi-angle processing (the rotatable worktable 20 has a built-in grating ruler or encoder to realize real-time position calibration and is connected to an external PLC control system. The rotatable worktable 20 is existing technology, so it will not be described in detail). The rotatable worktable 20 can drive the clutch housing to rotate, thereby drilling the indexed circular thread holes one by one.

[0030] The chip blowing and oil injection combined mechanism includes a cylinder 30 vertically mounted on a tooling plate 11, a mounting plate 31 fixedly connected to the telescopic end of the cylinder 30, an L-shaped support frame 32 fixed to the mounting plate 31 by bolts, a strip-shaped through groove 33 horizontally opened along the top of the L-shaped support frame 32, an arc-shaped slide plate 34 forming a sliding pair with the strip-shaped through groove 33, a chip blowing module and an oil injection module symmetrically arranged on the upper surface of the arc-shaped slide plate 34, a locking component located at the bottom of the arc-shaped slide plate 34, and two concentric arc guide rail grooves 35 opened on the upper surface of the arc-shaped slide plate 34. The arc-shaped slide plate 34 and the arc guide rail grooves 35 are both coaxial with the rotation axis of the rotatable worktable 20.

[0031] The locking assembly includes a slider 80 fixedly installed on the lower surface of the arc-shaped slide plate 34, a locking screw 81 fixedly installed on the lower end of the slider 80, and a locking nut 82 threadedly connected to the surface of the locking screw 81. The slider 80 slides in cooperation with the strip-shaped through groove 33. Lateral displacement adjustment is achieved by sliding the slider 80 along the strip-shaped through groove 33. Tightening the locking nut 82 and using the cooperation between the locking screw 81 and the locking nut 82 can fix the position of the arc-shaped slide plate 34 and prevent displacement caused by processing vibration.

[0032] The chip removal module includes a first mounting ring 40 and a chip removal air pipe 41 fixedly installed at the lower end of the first mounting ring 40, and the chip removal air pipe 41 is connected to an external air supply system. The oil injection module includes a second mounting ring 50, an oil injection pipe 51 fixedly installed at the lower end of the second mounting ring 50, and an oil supply assembly for supplying oil to the oil injection pipe 51. The oil supply assembly includes an oil storage tank 60 fixedly installed on the upper surface of the tooling plate 11, an oil supply cylinder 61 embedded in the inner wall of the oil storage tank 60, a piston rod 62 slidably connected to the inner wall of the oil supply cylinder 61, and an oil suction pipe 63 and an oil discharge pipe 64 respectively fixedly installed on the inner wall of the oil supply cylinder 61. The piston rod 62 is connected to a linkage component (a seal is provided between the piston rod 62 and the oil supply cylinder 61; specifically, the piston rod 62 head is integrated with a fluororubber O-ring (main seal), and the upper end of the piston rod 62 extends to the upper end of the oil reservoir 60; a polytetrafluoroethylene guide ring (auxiliary seal) is added to the inner wall of the oil supply cylinder 61 to form a multi-layer dynamic sealing structure; this technology is existing technology and therefore will not be described in detail). One-way valves are provided on the surfaces of the oil suction pipe 63 and the oil discharge pipe 64. One end of the oil discharge pipe 64 is connected to the interior of the oil injection pipe 51, and one end of the oil suction pipe 63 extends to the interior of the oil reservoir 60.

[0033] An adjustment structure is located inside the arc-shaped guide groove 35 and is used to adjust the distance between the chip blowing pipe 41 and the oil injection pipe 51. The adjustment structure includes an adjustment screw 70 that is slidably connected to the inner walls of the two arc-shaped guide grooves 35, and an adjustment nut 71 that is threadedly connected to the surface of the adjustment screw 70. The upper ends of the first mounting ring 40 and the second mounting ring 50 are both provided with threaded holes adapted to the adjustment screw 70. The adjustment screw 70 is connected to the first mounting ring 40 and the second mounting ring 50 through the threaded holes. Therefore, adjusting the screw 70... After sliding along the arc guide groove 35, the distance between the chip blowing pipe 41 and the oil injection pipe 51 can be adjusted. After tightening the adjusting nut 71, the chip blowing pipe 41 and the oil injection pipe 51 can be fixed, so as to adapt to the processing requirements of different indexed circular thread holes. The surfaces of the adjusting screw 70 and the locking screw 81 are covered with anti-slip pads, which are not shown in the figure. After drilling is completed, the worktable 20 can be rotated to rotate the thread bottom hole one by one to the direct below the chip blowing pipe 41. The high-pressure airflow sprayed by the chip blowing pipe 41 can blow out the iron chips in the thread bottom hole.

[0034] The linkage components include a pressure plate 90 fixedly connected to the left side of the mounting plate 31, a baffle 91 fixedly installed on the upper end of the piston rod 62, and a compression spring 92 sleeved on the surface of the piston rod 62. One end of the compression spring 92 abuts against the lower end of the baffle 91, and the other end of the compression spring 92 abuts against the upper end of the oil reservoir 60. The baffle 91 is located directly below the pressure plate 90.

[0035] When the cylinder 30 drives the mounting plate 31 to rise and fall, the pressure plate 90 fixed to its side moves synchronously. When the mounting plate 31 falls, the pressure plate 90 will contact the baffle 91, the compression spring 92 will store energy and push the piston rod 62 to move down. At this time, the one-way valve of the oil drain pipe 64 will open, and the lubricating oil will be sprayed out through the oil injection pipe 51. When the mounting plate 31 rises, the pressure plate 90 will disengage from the baffle 91, the compression spring 92 will release its elasticity and push the piston rod 62 to move up, and the one-way valve of the oil suction pipe 63 will open, completing the oil suction action of the oil storage tank 60. The reciprocating stroke of the piston rod 62 is controlled by the rising and falling frequency of the cylinder 30. Combined with the cooperation of the one-way valve group in the oil storage tank 60, the lubricating oil is quantitatively delivered. When the rotatable worktable 20 rotates the thread bottom hole after the chip removal is completed to directly below the oil injection pipe 51, the cylinder 30 will retract and drive the oil injection pipe 51 to approach the thread bottom hole, so that oil can be injected into the thread bottom hole, thereby extending the tap life and improving the surface finish of the thread.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
