Description

Technical Field

[0001] This utility model relates to the field of reamer manufacturing and processing technology, and in particular to a flexible hole machining reamer structure. Background Technology

[0002] Flexible hole reamers are mainly suitable for machining flexible materials or materials with a certain degree of elasticity, such as rubber, plastics, and soft metals. These materials are prone to deformation during machining, and ordinary reamers cannot guarantee machining accuracy and quality. Flexible hole reamers usually adopt a special design to adapt to changes in the shape and size of the hole during machining, thereby improving machining accuracy and surface quality.

[0003] Currently available flexible hole-making reamers are susceptible to damage from roughing drills when machining precision holes, resulting in flared holes and increased scrap rates. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a flexible hole-making reamer structure, which aims to improve the problem of flared holes that easily occur when reamers are used to process precision holes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexible hole-making reamer structure, comprising a first tool bar, a second tool bar fixedly connected to the bottom of the first tool bar, a cutter head fixedly connected to the bottom of the second tool bar, a housing provided on the top of the first tool bar, a first groove at the front of the housing, a second groove at the bottom of the housing, a detector fixedly connected to the bottom of the inner wall of the housing, an indicator light fixedly connected to the front of the detector, a probe fixedly connected to the bottom of the detector, a connector fixedly connected to the outer surface of the probe, and a quick-release assembly provided on the top of the first tool bar for quick disassembly of the reamer.

[0006] Preferably, the quick-release assembly includes a motor, which is fixedly connected to the housing. A connecting ring is fixedly connected to the output end of the motor. Evenly distributed grippers are fixedly connected to the bottom of the connecting ring. A fixing member is fixedly connected to the bottom of the grippers. A fixing ring is provided on the outer surface of the grippers. A slider is slidably connected to the outer surface of the fixing ring.

[0007] Preferably, a third groove is provided on the right side of the outer casing.

[0008] Preferably, the right side of the slider extends through and to the right side of the third groove, and the slider and the third groove are slidably connected.

[0009] Preferably, a sound generator is fixedly connected to the top of the detector.

[0010] Preferably, the front side of the indicator light extends through and to the front side of the housing.

[0011] Preferably, the connector is slidably connected to the second groove.

[0012] Preferably, the probe extends through and to the bottom of the housing, and the bottom of the probe fits tightly against the first cutter bar.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by reducing the diameter of the second tool holder, soft deformation compensation is provided for the working process of the reamer. By working in conjunction with the first tool holder 1, the influence of concentricity on the machining can be corrected. By setting a detector and probe in the housing to detect the working process of the reamer, the problem of flared holes that are easy to occur when the reamer is machining precision holes is solved.

[0015] 2. In this utility model, by setting a connecting ring, a gripper, and a fixing ring between the motor output end and the first cutter bar, the gripper is relaxed and tightened when the fixing ring slides up and down, so that the bottom fixing part of the gripper relaxes and tightly holds the first cutter bar, thus achieving the purpose of disassembly and assembly. The fixing ring is controlled to move up and down by a slider, which solves the problem of troublesome installation and disassembly of the reamer during operation. Attached Figure Description

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1-3 This utility model provides an embodiment of a flexible hole-making reamer structure, including a first tool bar 1, a second tool bar 2 fixedly connected to the bottom of the first tool bar 1, a cutter head 3 fixedly connected to the bottom of the second tool bar 2, a housing 4 provided on the top of the first tool bar 1, a first groove 5 at the front of the housing 4, a second groove 6 at the bottom of the housing 4, a detector 7 fixedly connected to the bottom of the inner wall of the housing 4, an indicator light 9 fixedly connected to the front of the detector 7, a probe 10 fixedly connected to the bottom of the detector 7, a connector 11 fixedly connected to the outer surface of the probe 10, and a quick-release assembly provided on the top of the first tool bar 1 for quick disassembly of the reamer.

[0024] Specifically, by setting a detector 7 and a probe 10 in the housing 4, when the first tool holder 1 rotates and a radial offset exceeds a predetermined value, the detector 7 detects this, controls the indicator light 9 to flash, and controls the buzzer 8 to emit a beep, indicating that the reamer has a radial offset. The work is then paused to inspect the reamer, solving the problem that radial offset of the reamer is not easy to detect during operation. The reamer consists of a first tool holder 1, a second tool holder 2, and a cutter head 3, where the cutter head 3 is the effective working part of the reamer. The second tool holder has a reduced diameter design to provide soft deformation compensation. By working in conjunction with the first tool holder 1, it can correct some of the concentricity effects on machining. When machining precision holes, the reamer is easily affected by roughing drill bits. This design can provide flexible compensation during reaming to avoid the formation of flared holes.

[0025] Reference Figure 4 The quick-release assembly includes a motor 12, which is fixedly connected to the housing 4. A connecting ring 13 is fixedly connected to the output end of the motor 12. Evenly distributed grippers 14 are fixedly connected to the bottom of the connecting ring 13. A fixing member 16 is fixedly connected to the bottom of the grippers 14. A fixing ring 15 is provided on the outer surface of the grippers 14. A slider 17 is slidably connected to the outer surface of the fixing ring 15.

[0026] Specifically, by setting a connecting ring 13, a gripper 14, and a fixing ring 15 between the output end of the motor 12 and the first cutter bar 1, the gripper 14 is relaxed and tightened when the fixing ring 15 slides up and down, so that the bottom fixing part 16 of the gripper 14 relaxes and locks the first cutter bar 1, thus achieving the purpose of disassembly and assembly. The fixing ring 15 is controlled to move up and down by the slider 17, which solves the problem of troublesome installation and disassembly of the reamer during operation.

[0027] Reference Figure 4 The outer casing 4 has a third groove 18 on its right side.

[0028] Specifically, the slider 17 is placed through the third groove 18.

[0029] Reference Figure 4 The slider 17 extends through and to the right side of the third groove 18, and the slider 17 and the third groove 18 are slidably connected.

[0030] Specifically, the slider 17 is slidably connected to the third groove 18, and the fixing ring 15 can be controlled from the outer shell 4.

[0031] Reference Figure 3 A speaker 8 is fixedly connected to the top of the detector 7.

[0032] Specifically, the position of the sound generator 8 corresponds to the first groove 5. When the sound generator 2 emits a buzzer, the sound is transmitted through the first groove 5.

[0033] Reference Figure 1 The indicator light 9 extends through the front side and into the front side of the housing 4.

[0034] Specifically, indicator light 9 extends to the outside of housing 4 to indicate to the operator that the reamer is radially offset.

[0035] Reference Figure 3 The connector 11 is slidably connected to the second groove 6.

[0036] Specifically, the connector 11 is fixed to the probe rod 10. When the probe rod 10 vibrates due to the rotation of the first cutter bar 1, the connector 11 slides left and right on the second groove 6, preventing debris from entering the housing 4 through the second groove 6 during operation.

[0037] Reference Figure 3 The probe rod 10 penetrates and extends to the bottom of the housing 4, and the bottom of the probe rod 10 is in close contact with the first cutter bar 1.

[0038] Specifically, during operation, the bottom of the probe 10 is in close contact with the first tool bar 1 to continuously detect the radial rotation of the first tool bar 1.

[0039] Working principle: By setting a detector 7 and a probe 10 in the housing 4, when the first cutter bar 1 rotates and the radial deviation exceeds a predetermined value, the detector 7 detects this, controls the indicator light 9 to flash, and controls the buzzer 8 to emit a beep, indicating that the reamer has radially deviated. The work is then paused for inspection of the reamer. This solves the problem that radial deviation of the reamer is not easily detected during operation. The reamer consists of a first cutter bar 1, a second cutter bar 2, and a cutter head 3, where the cutter head 3 is the effective working part of the reamer. The second cutter bar has a reduced diameter design to provide soft deformation compensation, and works in conjunction with the first cutter bar 1. This design can correct the impact of concentricity on machining. When machining precision holes, reamers are easily affected by roughing drills. This design can provide flexible compensation during reaming to avoid the formation of flared holes. By setting a connecting ring 13, a jaw 14, and a fixing ring 15 between the output end of the motor 12 and the first tool holder 1, the jaw 14 is relaxed and tightened when the fixing ring 15 slides up and down, so that the bottom fixing part 16 of the jaw 14 relaxes and locks the first tool holder 1, achieving the purpose of disassembly and assembly. The fixing ring 15 is controlled to move up and down by the slider 17, which solves the problem of troublesome installation and disassembly of the reamer during operation.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
