Description

Technical Field

[0001] The present invention relates to the technical field of internal thread processing, and particularly relates to an internal thread processing device for the shell of an intelligent measuring instrument. Background Art

[0002] Intelligent measuring instruments are widely used in many fields such as industrial automation, scientific research, and medical treatment. Its shell not only plays a role in protecting the internal precision electronic components, but also has an important impact on the overall performance, stability, and appearance quality of the instrument. The internal thread on the shell is used to connect various components to ensure the integrity of the instrument structure.

[0003] As described in a processing device with the patent number CN112894035B, this processing device drives a rotating component through a motor, and through the force conduction between structures, synchronously drives four telescopic rods and a tap head to rotate. At the same time, when the disc in the rotating component rotates, it contacts the air guide ring, opens the closed air outlet, so that the air pressure in the air guide ring enters the air pressure rod through the corrugated pipe, and pushes the four tap heads to extend and jointly process the thread. However, this processing device does not process the waste chips remaining after the tap head processing, and the waste chips remaining on the tap head will change the relative position and cutting angle between the tap and the workpiece, resulting in dimensional deviation of the processed internal thread, leading to a decrease in thread accuracy, affecting the fitting accuracy between the shell of the intelligent measuring instrument and other parts, and further affecting the overall performance and stability of the instrument.

Detailed implementation manner

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0036] Refer to Figures 1 - 13 , an internal thread processing device for an intelligent measurement instrument housing, including a machine tool 1. A feeding component is provided on the machine tool 1, and the feeding component is used for the transportation of materials. A tapping component is also provided on the machine tool 1, and the tapping component is used to process internal threads at the four corners of the materials.

[0037] The feeding component includes a turntable 21, a material box 30, a clamping rod 27, and a rotating mechanism. The rotating mechanism is used to drive the turntable 21 to rotate. The turntable 21 is rotatably arranged on the machine tool 1. Four material boxes 30 are fixedly connected to the turntable 21. Every two clamping rods 27 are fixedly connected to the inner wall of the material box 30.

[0038] The chip removal component includes a telescopic airbag 44, a brush plate 45, and a pump air mechanism for expanding and contracting the telescopic airbag 44. A receiving box 46 is provided on the machine tool 1. The telescopic airbag 44 is slidably arranged on the receiving box 46. The brush plate 45 is fixedly connected to the side wall of the telescopic airbag 44. A third baffle 48 is provided on the receiving box 46. A second electric push rod 47 is fixedly connected to the third baffle 48. The telescopic end of the second electric push rod 47 is fixedly connected to the telescopic airbag 44.

[0039] The tapping assembly includes a tap 52, a second motor 9, and a drive mechanism for driving the tap 52 downward. A slide 7 is located above the turntable 21 and is fixedly connected to the second motor 9, which in turn is fixedly connected to the tap 52. It should be noted that after the tap 52 completes tapping, it moves upward, driven by the slide 7. The second motor 9 controls the reverse rotation of the tap 52. The telescopic airbag 44, driven by the pumping mechanism, continuously expands and contracts, simultaneously driving the brush plate 45 to reciprocate. The second electric push rod 47 pushes the telescopic airbag 44 toward the tap 52, where the brush plate 45 wipes away any remaining debris.

[0040] The drive mechanism includes a first motor 8, a screw 3, a rotating wheel 4, and a conveyor belt 5. The machine tool 1 is equipped with two drive boxes 2. The two sets of screws 3 are rotatably mounted within the drive boxes 2. The screws 3 are fixedly connected to the rotating wheels 4. Each set of rotating wheels 4 is connected to each other via a conveyor belt 5. A slide 7 slides on the screws 3. A third guide rod 6 is fixedly connected to the drive box 2. The slide 7 slides on the third guide rod 6. The first motor 8 is fixedly connected to the screw 3. It should be noted that due to the limiting effect of the third guide rod 6, the slide 7 can only perform an upward and downward sliding motion on the screw 3.

[0041] The rotating mechanism includes a first rotating shaft 20, a first bevel gear 19, a second bevel gear 18, a second rotating shaft 17, a one-way bearing 15, a first gear 14, and a third rotating shaft 16. The third rotating shaft 16 is rotatably connected to the side wall of the machine tool 1. The first gear 14 is fixedly connected to the third rotating shaft 16. The first gear 14 is fixedly connected to the one-way bearing 15. The one-way bearing 15 is fixedly connected to the second rotating shaft 17. The second rotating shaft 17 is fixedly connected to the second bevel gear 18. The first rotating shaft 20 is rotatably connected to the turntable 21. The first rotating shaft 20 is fixedly connected to the first bevel gear 19. The first bevel gear 19 meshes with the second bevel gear 18. It should be noted that the first gear 14 is fixedly connected to the outer ring of the one-way bearing 15, the inner ring of the one-way bearing 15 is fixedly connected to the second rotating shaft 17, and the number of teeth of the first bevel gear 19 is four times the number of teeth of the second bevel gear 18.

[0042] A first electric push rod 11 is fixedly connected to the side wall of the machine tool 1. The telescopic end of the first electric push rod 11 is fixedly connected to a first rack 12.

It should be noted that the number of teeth of the first gear 14 is the same as that of the first rack 12. Under the limiting action of the first guide rod 13, the first rack 12 can only slide back and forth along its direction. When the first electric push rod 11 extends, the first gear 14 rotates forward, driving the outer ring of the one-way bearing 15 to rotate synchronously. At this time, the outer ring of the one-way bearing 15 can drive the inner ring to rotate together, thereby driving the second rotating shaft 17, the second bevel gear 18, the first bevel gear 19, the first rotating shaft 20, and the turntable 21 to rotate forward. When the first electric push rod 11 retracts, due to the one-way torque transmission characteristic of the one-way bearing 15, the inner ring will not be driven to rotate at this time, so the second rotating shaft 17, the second bevel gear 18, the first bevel gear 19, the first rotating shaft 20, and the turntable 21 will not rotate either. Therefore, when the first gear 14 rotates back and forth, it will only drive the turntable 21 to rotate in one direction.

[0043] The air pumping mechanism includes an air cylinder 39, a push rod 38, a piston 50, a second rack 37, and a spring 49. A support plate 42 is provided above the machine tool 1.

[0044] A pull rod 31 is fixedly connected to the side wall of the slide plate 7. The end of the pull rod 31 away from the drive box 2 is fixedly connected to a third rack 32. Two first baffles 36 are fixedly connected to the support plate 42. A fourth rotating shaft 35 is rotatably connected through the two first baffles 36. An incomplete gear 34 and a second gear 33 are fixedly connected to the fourth rotating shaft 35. The incomplete gear 34 meshes with the second rack 37. The second gear 33 meshes with the third rack 32. A second baffle 41 is fixedly connected to the support plate 42. A second guide rod 51 is fixedly connected between the second baffle 41 and the drive box 2. The second rack 37 slides on the second guide rod 51. It should be noted that under the limiting action of the second guide rod 51, the second rack 37 can only slide back and forth along its direction.

[0045] An opening 10 is provided on the side wall of the drive box 2. Two baffle strips 22 are provided on the turntable 21. The baffle strips 22 are fixedly connected to the drive box 2 through a connecting rod 28. A support 53 is provided on the machine tool 1. A third electric push rod 54 is fixedly connected to the side wall of the support 53.

[0046] The turntable 21 is provided with a first through hole 23, a second through hole 24, and a third through hole 25. A waste box 29 is provided below the turntable 21 on the side close to the tap 51. It should be noted that the four corners of the instrument housing 26 are directly below the second through hole 24, and the diameter of the second through hole 24 is larger than the outer diameter of the tap 52. The third through hole 25 is arranged in the middle of the two corners on both sides of the instrument housing 26, and the first through hole 23 is arranged outside the clamping rod 27.

[0047] In the present invention, first, the instrument housing 26 is conveyed to the material frame 30 on the turntable 21 through a conveying device. Since the material frame 30 is fixedly connected to the turntable 21, every two clamping rods 27 are fixedly connected to the inner wall of the material frame 30. Because there are two baffle strips 22 on the turntable 21, the baffle strips 22 are fixedly connected to the drive box 2 through a connecting rod 28. The third rotating shaft 16 is rotatably connected to the side wall of the machine tool 1. The first gear 14 is fixedly connected to the third rotating shaft 16. The first gear 14 is fixedly connected to the one-way bearing 15. The one-way bearing 15 is fixedly connected to the second rotating shaft 17. The second rotating shaft 17 is fixedly connected to the second bevel gear 18. The first rotating shaft 20 is rotatably connected to the turntable 21. The first rotating shaft 20 is fixedly connected to the first bevel gear 19. The first bevel gear 19 meshes with the second bevel gear 18. The telescopic end of the first electric push rod 11 is fixedly connected to the first rack 12. The first rack 12 meshes with the first gear 14. The side wall of the machine tool 1 is fixedly connected with a first guide rod 13. The first rack 12 slides on the first guide rod 13.

[0048] It should be noted that the first gear 14 is fixedly connected to the outer ring of the one-way bearing 15. The inner ring of the one-way bearing 15 is fixedly connected to the second rotating shaft 17. The number of teeth of the first gear 14 is the same as that of the first rack 12. The number of teeth of the first bevel gear 19 is four times that of the second bevel gear 18. Therefore, the first electric push rod 11 pushes the first rack 12 every once in a while, causing the turntable to rotate a quarter of a circle, so as to rotate the material frame 30 containing the instrument housing 26 below the tap 52. The instrument housing 26 is stuck in the material frame 30 under the limiting action of the material frame 30, the clamping rod 27, and the baffle strip 22.

[0049] The machine tool 1 is provided with two groups of drive boxes 2. Two groups of screws 3 are rotatably arranged in the drive boxes 2. The screws 3 are fixedly connected to the rotating wheels 4. The rotating wheels 4 in each group are drivingly connected by a conveyor belt 5. The slide plate 7 slides on the screws 3. A third guide rod 6 is fixedly connected in the drive box 2. The slide plate 7 slides on the third guide rod 6. The first motor 8 is fixedly connected to the screw 3. The slide plate 7 is fixedly connected to the second motor 9. The second motor 9 is fixedly connected to the tap 52. Therefore, when the first motor 8 is started at this time, the slide plate 7 slides on the screw 3, thereby driving the second motor 9 and the tap 52 to slide downward. At this time, the second motor 9 is started synchronously, driving the tap 52 to thread the four corners of the instrument housing 26 downward. It should be noted that directly below the four corners of the instrument housing 26 is the second through hole 24, and the diameter of the second through hole 24 is larger than the outer diameter of the tap 52. The third through hole 25 is arranged in the middle of the two corners on both sides of the instrument housing 26. The first through hole 23 is arranged outside the clamping rod 27. Therefore, the tap 52 can perform through threading on the four corners of the instrument housing 26, and the waste chips generated by threading fall into the waste box 29 below the turntable 21 through the first through hole 23 and the third through hole 25.

[0050] After threading is completed, the first motor 8 and the second motor 9 are driven to reverse, driving the tap 52 to move upward. Synchronously, since there is a support plate 42 above the machine tool 1, the support plate 42 is fixedly connected to the machine tool 1 through a support column 43. The second rack 37 is slidably arranged on the support plate 42. The two ends of the second rack 37 are respectively fixedly connected to the push rod 38 and the spring 49. The other end of the push rod 38 is fixedly connected to the piston 50. The other end of the spring 49 is fixedly connected to the side wall of the drive box 2. The piston 50 is slidably arranged in the air cylinder 39. The side wall of the telescopic airbag 44 is fixedly connected to an air pipe 40 and a brush plate 45. The other end of the air pipe 40 is fixedly connected to the air cylinder 39. The side wall of the slide plate 7 is fixedly connected to a pull rod 31. The end of the pull rod 31 away from the drive box 2 is fixedly connected to a third rack 32. Two first baffles 36 are fixedly connected to the support plate 42. A fourth rotating shaft 35 is rotatably connected through the two first baffles 36. An incomplete gear 34 and a second gear 33 are fixedly connected to the fourth rotating shaft 35. The incomplete gear 34 meshes with the second rack 37. The second gear 33 meshes with the third rack 32. A second baffle 41 is fixedly connected to the support plate 42. A second guide rod 51 is fixedly connected between the second baffle 41 and the drive box 2. Therefore, when the third rack 32 moves upward or downward, the air cylinder 39 can be pumped. The telescopic airbag 44 expands and contracts continuously under the drive of the pumping mechanism, and at the same time drives the brush plate 45 to reciprocate. The second electric push rod 47 pushes the telescopic airbag 44 to the position of the tap 52. The brush plate 45 wipes the residual waste chips on the tap 52. After the tap 52 is wiped clean and moved upward, the second electric push rod 47 retracts, and at the same time the wiped waste chips fall into the waste box 29 below the turntable 21 through the first through hole 23 and the third through hole 25.

[0051] At this time, the first electric push rod 11 further pushes the first rack 12 to rotate the turntable by a quarter of a turn, rotates the instrument housing 26 after tapping to the other side of the machine tool 1, and the third electric push rod 54 pushes it out and conveys it away through the conveying device.

[0052] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
