Description

Technical Field

[0001] The invention relates to the technical field of internal thread processing of a transmission shaft, and more specifically, to a forming and chip removing processing device for the internal thread of a transmission shaft of railway equipment. Background Art

[0002] In railway equipment, the drive shaft is an important component of EMUs and locomotives. The main function of the drive shaft is to transmit the traction of the locomotive to the drive wheels so that the train can operate normally. Usually the drive shaft needs to be connected to the universal joint through screws, screw holes need to be drilled on the outside of the universal joint, and threaded holes also need to be drilled on the outside of the drive shaft.

[0003] The existing transmission shaft thread drilling method is to first drill a screw through hole on the outside of the universal joint, then drill a threaded hole on the outside of the transmission shaft, and finally assemble the two sides with screws. This drilling method is likely to cause some holes to be misaligned due to processing reasons during subsequent assembly, causing the threaded holes and threaded through holes to be misaligned, thereby making it impossible to accurately complete the installation when the universal joint and transmission shaft are assembled subsequently.

[0004] Before thread forming, threaded holes need to be drilled first and then tapping is performed. When iron chips stick to the surface of the tap, the staff will use an air gun or cutting fluid to wash away the iron chips on the surface. However, when drilling threaded holes, due to different processing reasons, not only flaky iron chips stick to the chip groove of the tap will appear, but also annular iron chips surrounding the chip groove of the tap and spiral iron chips clamped in the chip groove of the tap will appear. When blowing air or flushing cutting fluid on the iron chips in the above situations, only the flaky iron chips can be washed away, the surrounding annular iron chips will circle around the chip groove of the tap, and the clamped spiral iron chips will not move at all. The iron chips in special situations cannot be effectively washed away, resulting in the inability to accurately drill holes in the workpiece later.

[0005] Therefore, it is necessary to design a transmission shaft internal thread forming and chip removal processing device that can automatically assemble and process and automatically clean iron chips in different situations to improve the above-mentioned technical problems.

[0059] Specifically, the second clamping assembly 44 is used to clamp one end of the transmission shaft 24 , the extension and retraction of the output end of the second cylinder 42 is used to control the movement of the transmission shaft 24 , and the rotation of the output end of the second rotary motor 45 is used to control the rotation of the universal joint 23 .

[0060] When it is necessary to assemble and drill the transmission shaft 24 and the universal joint 23, the sliding of the transmission end of the first slide 32 controls the first clamp 36 to move to the top of the transmission shaft 24, and the sliding of the transmission end of the second slide 33 controls the first clamp 36 to slide downward, and the first clamp 36 clamps the transmission shaft 24.

[0062] In the second embodiment, before forming the thread on the transmission shaft 24, it is necessary to punch a hole, then chamfer the entrance end of the hole, and finally tap the inside of the hole. This step requires the staff or machine to repeatedly disassemble and replace different taps, which slows down the thread forming speed of the transmission shaft 24, thereby reducing the thread forming efficiency of the transmission shaft 24. Therefore, the following structure is designed to solve the above technical problems.

[0063] See also Figure 6 The drilling mechanism 6 includes a second base 61, which is fixedly connected to the upper side of the workbench 1, and a first motor 62 is fixedly connected to the upper side of the second base 61, and a screw rod 64 is fixedly connected to the output end of the first motor 62, and the other end of the screw rod 64 is bearing-connected to the second base 61, and a slide rail 63 is fixedly connected to one side of the second base 61, and a slide seat 65 is slidably connected to one side of the slide rail 63, and the slide seat 65 is ball-connected to the screw rod 64, and an adjustment component 66 is provided on one side of the slide seat 65, and a camera 67 is fixedly connected to one side of the second base 61, and a cleaning component 68 is provided on one side of the camera 67 and a grinding component 69 is provided on the other side.

[0064] Specifically, the adjusting assembly 66 is used to adjust the taps with different functions to perform drilling, chamfering and tapping on the transmission shaft 24 in turn, the cleaning assembly 68 is used to clean the iron chips of different conditions and different heights on the chip removal groove of the tap, and the grinding assembly 69 is used to grind the forming teeth stuck inside the thread groove. The rotation of the output end of the first motor 62 is used to control the adjustment assembly 66 to move up and down, thereby controlling the adjustment assembly 66 to approach or move away from the transmission shaft 24 and the universal joint 23.

[0065] See also Figure 7 The adjustment component 66 includes a U-shaped frame 661, which is fixedly connected to one side of the slide 65. The inside of the U-shaped frame 661 is fixedly connected to a third rotating motor 662, the output end of the third rotating motor 662 is fixedly connected to a turntable 663, and the outer side of the turntable 663 is evenly fixedly connected to a fourth motor 667, a third motor 666 and a second motor 664.

[0066] The rotation of the output end of the third rotary motor 662 is used to control the rotation of the punching tap 668 , the chamfering tap 669 and the threading tap 665 , so as to replace the taps with different functions.

[0067] The output end of the fourth motor 667 is fixedly connected to the first clamping disk, the clamping end of the first clamping disk is fixedly connected to the punching tap 668, the output end of the third motor 666 is fixedly connected to the second clamping disk, the clamping end of the second clamping disk is fixedly connected to the chamfering tap 669, the output end of the second motor 664 is fixedly connected to the third clamping disk, the clamping end of the third clamping disk is fixedly connected to the thread tap 665.

[0068] Specifically, the fourth motor 667 , the third motor 666 , and the second motor 664 are used to control the rotation of the punching tap 668 , the chamfering tap 669 , and the threading tap 665 , respectively, so as to perform punching, chamfering, and tapping on the transmission shaft 24 in sequence.

[0069] In the initial state, the output end of the punching tap 668 faces downward, and the transmission shaft 24 and the universal joint 23 are assembled. When the internal thread of the transmission shaft 24 is formed, the output end of the first motor 62 rotates clockwise to control the punching tap 668 to move downward, thereby drilling holes in the transmission shaft 24 and the universal joint 23. When the drilling is completed, the output end of the first motor 62 rotates counterclockwise to control the punching tap 668 to move upward, and the second clamping mechanism 5 stops clamping the universal joint 23. The transmission mechanism 3 clamps the universal joint 23 with the hole drilled and transmits it away. The second clamping mechanism 5 clamps the other end of the transmission shaft 24, and the output end of the third rotating motor 662 rotates clockwise. The needle rotates sixty degrees, at this time the output end of the chamfering tap 669 faces downward, the output end of the first motor 62 rotates clockwise to control the chamfering tap 669 to move downward, thereby chamfering the transmission shaft 24, when the chamfering is completed, the output end of the first motor 62 rotates counterclockwise to control the chamfering tap 669 to move upward, the output end of the third rotating motor 662 rotates clockwise sixty degrees again, at this time the output end of the thread tap 665 faces downward, the output end of the first motor 62 rotates clockwise to control the thread tap 665 to move downward, thereby tapping the transmission shaft 24, when the tapping is completed, the output end of the first motor 62 rotates counterclockwise to control the thread tap 665 to move upward.

[0070] The third rotating motor 662 controls the punching tap 668, the chamfering tap 669 and the threading tap 665 to rotate, thereby replacing taps with different functions. This process does not require repeated disassembly of the taps and movement of the processed products, thereby accelerating the tapping speed of the transmission shaft 24 and achieving a high thread forming efficiency.

[0071] Embodiment 3: Before thread forming, it is necessary to drill a threaded hole first and then perform tapping. When iron chips stick to the surface of the tap, the staff will use an air gun or cutting fluid to wash away the iron chips on the surface. However, when drilling threaded holes, due to different processing reasons, not only will there be flaky iron chips stuck to the chip groove of the tap, but there will also be annular iron chips surrounding the chip groove of the tap and spiral iron chips clamped in the chip groove of the tap. When blowing air or flushing cutting fluid on the iron chips in the above situation, only the flaky iron chips can be washed away, the surrounding annular iron chips will circle around the chip groove of the tap, and the clamped spiral iron chips will remain motionless. The iron chips in special situations cannot be effectively washed away, resulting in the inability to accurately drill holes in the workpiece later. Therefore, the following structure is designed to solve the above technical problems.

[0072] See also Figure 8 The cleaning assembly 68 includes a fourth cylinder 683, which is fixedly connected to one side of the second base 61. The output end of the fourth cylinder 683 is fixedly connected to a slider 682. The slider 682 is slidably connected to the second base 61 and the upper side is fixedly connected to the third cylinder 681. The output end of the third cylinder 681 is fixedly connected to a positioning block 684.

[0073] Specifically, the extension and retraction of the output end of the fourth cylinder 683 is used to control the first clamping block 686 and the second clamping block 689 to move up and down, and the extension and retraction of the output end of the third cylinder 681 is used to control the first clamping block 686 and the second clamping block 689 to move closer to or away from the tap.

[0074] A first micro motor 687 is fixedly connected to one side of the positioning block 684, a first connecting rod 685 is fixedly connected to one side of the positioning block 684, a first clamping block 686 is fixedly connected to the other end of the first connecting rod 685, an output end of the first micro motor 687 is fixedly connected to a second connecting rod 688, and a second clamping block 689 is fixedly connected to the other end of the second connecting rod 688.

[0075] Specifically, the rotation of the output end of the first micro motor 687 is used to control the rotation of the second clamp 689, so that one end of the second clamp 689 is close to or away from one end of the first clamp 686, thereby clamping the iron filings on the punching tap 668. The first clamp 686 and the second clamp 689 are triangular in shape.

[0076] See also Fig.10 , a is the flaky iron chips stuck on the chip groove of the tap, b is the annular iron chips surrounding the chip groove of the tap, and c is the spiral iron chips clamped in the chip groove of the tap.

[0077] The camera 67 first takes an image of the tap surface, and converts the photographed image into an electrical signal and transmits it to the control box. A database is provided inside the control box, and identification photos of different positions and different winding conditions of iron chips on the punching tap 668 are provided inside the database. When the control box receives the photo sent by the camera 67, it compares it with the identification photos of different winding conditions of iron chips on the punching tap 668 in the internal database, and pre-identifies the different winding conditions of iron chips on the punching tap 668, and then determines the punching tap 668 according to the obtained conditions. The control box then compares the photographs of the punching tap 668 with the identification photos of the iron filings at different positions on the punching tap 668 to identify the specific positions of the iron filings on the punching tap 668, and based on the obtained photographs of the punching tap 668, distinguishes the specific positions of the iron filings into three positions: above the punching tap 668, in the middle of the punching tap 668, and below the punching tap 668.

[0078] In the initial state, the universal joint water gun 55 is aimed at the bottom of the punching tap 668. When the control box determines that the flaky iron filings are adhered to the punching tap 668, it indicates that the flaky iron filings need to be flushed away by cutting fluid. The solenoid valve 54 opens, and the universal joint water gun 55 starts to spray cutting fluid. The output end of the first motor 62 rotates clockwise to control the punching tap 668 to move downward, and the output end of the fourth motor 667 rotates to control the punching tap 668 to rotate. The universal joint water gun 55 evenly sprays the surface of the punching tap 668 to flush away the flaky iron filings on its surface.

[0079] When the control box determines that the ring-shaped iron filings are surrounding the punching tap 668, it means that the ring-shaped iron filings need to be clamped and pulled away from the punching tap 668, the output end of the third cylinder 681 extends, the output end of the first micro motor 687 rotates counterclockwise, and the second clamp block 689 and the first clamp block 686 are controlled to clamp the ring-shaped iron filings on the punching tap 668. The second clamp block 689 and the first clamp block 686 clamp one end of the ring-shaped iron filings, the output end of the third cylinder 681 retracts, and the ring-shaped iron filings are pulled away from the punching tap 668. The output end of the first micro motor 687 rotates clockwise, and the second clamp block 689 and the first clamp block 686 are controlled to throw the pulled ring-shaped iron filings into the inside of the collection box 7.

[0080] When the control box determines that one end of the spiral iron filings is clamped on the punching tap 668, it indicates that the spiral iron filings need to be clamped and pulled away from the punching tap 668, the output end of the third cylinder 681 extends, the output end of the first micro motor 687 rotates counterclockwise, and the second clamp block 689 and the first clamp block 686 are controlled to clamp the spiral iron filings on the punching tap 668. The second clamp block 689 and the first clamp block 686 clamp one end of the spiral iron filings. In order to prevent the other end of the spiral iron filings from being pulled tighter while one end is pulled, the output end of the fourth motor 667 rotates counterclockwise, opposite to the direction in which the spiral iron filings are wound, and the spiral iron filings are sent and no longer clamped. The output end of the third cylinder 681 retracts to pull the spiral iron filings away from the punching tap 668, and the output end of the first micro motor 687 rotates clockwise to control the second clamp block 689 and the first clamp block 686 to throw the pulled spiral iron filings into the collection box 7.

[0081] In the initial state, the second clamping block 689 and the bottom surface of the punching tap 668 are at the same horizontal plane. When the control box determines that there are iron filings above the punching tap 668, the output end of the fourth cylinder 683 is fully extended, the output end of the third cylinder 681 is extended, and the output end of the first micro motor 687 rotates counterclockwise, controlling the second clamping block 689 and the first clamping block 686 to clamp the annular iron filings and spiral iron filings above the punching tap 668.

[0082] When the control box determines that there are iron filings in the middle of the punching tap 668, the output end of the fourth cylinder 683 extends two-thirds, the output end of the third cylinder 681 extends, and the output end of the first micro motor 687 rotates counterclockwise, controlling the second clamping block 689 and the first clamping block 686 to clamp the annular iron filings and spiral iron filings in the middle of the punching tap 668.

[0083] When the control box determines that there are iron filings above the punching tap 668, the output end of the fourth cylinder 683 extends one-third, the output end of the third cylinder 681 extends, and the output end of the first micro motor 687 rotates counterclockwise to control the second clamping block 689 and the first clamping block 686 to clamp the annular iron filings and spiral iron filings below the punching tap 668.

[0084] The camera 67 detects different positions and different winding conditions of iron filings on the punching tap 668, and the control box determines the specific position of the iron filings on the punching tap 668 and the winding condition of the iron filings, thereby quickly and accurately removing the iron filings in different positions and under different conditions, achieving the effect of high efficiency and high accuracy in iron filing removal.

[0085] Embodiment 4: During the tapping process, if the manufacturing quality of the forming tap is poor, the forming teeth may break when working under high stress, and too high a rotation speed or improper feed rate may also cause the forming teeth of the tap to be subjected to excessive stress and break. The broken forming teeth will be stuck inside the thread groove, causing the subsequent screws to be blocked and unable to be completely tightened. Therefore, the following structure is designed to solve the above technical problems.

[0086] See also Fig. 9 The grinding assembly 69 includes a fourth rotating motor 691, which is fixedly connected to one side of the second base 61. The output end of the fourth rotating motor 691 is fixedly connected to the first arm 692, the outer side of the first arm 692 is fixedly connected to the fifth motor 693, and the other end of the first arm 692 is hinged to an electric push rod 694.

[0087] Specifically, the rotation of the output end of the fourth rotating motor 691 is used to control the grinding direction of the threaded hole by the grinding head, the rotation of the output end of the fifth motor 693 is used to control the grinding angle of the threaded hole by the grinding head, the extension of the output end of the electric push rod 694 is used to control the grinding depth of the threaded hole by the grinding head, and the rotation of the output end of the second micro motor 695 is used to control the rotation of the grinding head.

[0088] The output end of the fifth motor 693 is fixedly connected to the electric push rod 694, the output end of the electric push rod 694 is fixedly connected to the second micro motor 695, and the output end of the second micro motor 695 is fixedly connected to a grinding head, which is spherical in shape.

[0089] Specifically, when it is necessary to grind the formed tooth stuck inside the threaded hole, the first clamping mechanism 4 and the second clamping mechanism 5 control the transmission shaft 24 to rotate ninety degrees clockwise to align the threaded hole with the grinding head, the output end of the second micro motor 695 rotates to control the rotation of the grinding head, the output end of the electric push rod 694 extends to control the grinding depth of the threaded hole by the grinding head, the output end of the fourth rotary motor 691 rotates to control the grinding direction of the threaded hole by the grinding head, and the output end of the fifth motor 693 rotates to control the grinding angle of the threaded hole by the grinding head. When the grinding of the formed tooth is completed, the first clamping mechanism 4 and the second clamping mechanism 5 control the transmission shaft 24 to rotate ninety degrees counterclockwise, the solenoid valve 54 opens, and the output end of the universal joint water gun 55 ejects cutting fluid to flush out the formed tooth fragments inside the threaded hole.

[0090] By providing a grinding component 69, the molded teeth at any position inside the threaded hole can be ground, effectively preventing broken molded teeth from getting stuck inside the threaded groove, causing subsequent screws to be blocked and unable to be completely tightened, thereby achieving a high cleaning efficiency of the molded teeth.
