Description

Technical Field

[0001] This invention relates to the field of deburring equipment technology, specifically to a flexible deburring device. Background Technology

[0002] Burrs refer to residual chips and extremely fine microscopic metal particles on the surface of metal parts. The more burrs there are, the lower the machining quality of the metal part. Burrs on the wall surface of the inner hole of a metal part are among the most difficult to remove. Related technologies use flexible reamers to remove burrs from inner holes. However, since only the cutting head of the flexible reamer is flexible, it is only suitable for shallow inner holes. When deburring deep holes, the shank needs to extend into the deep hole as well. Since the shank is not flexible, there is a problem that the shank may get stuck or bend inside the deep hole. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention propose a flexible deburring device, which uses a coupling to connect the reamer's handle to a first rotary drive component, and uses a universal bearing to mount the reamer's handle on a frame, thereby making the reamer's handle flexible.

[0004] The flexible deburring device of this invention includes:

[0005] frame;

[0006] A first rotation drive component is mounted on the frame;

[0007] A coupling, one end of which is connected to the first rotational drive component;

[0008] A reamer having a cutting head and a shank, wherein one end of the shank away from the cutting head is connected to the other end of the coupling;

[0009] The universal bearing is mounted on the frame, and the reamer passes through the universal bearing.

[0010] The flexible deburring device of this invention is equipped with a coupling to connect the reamer's shank to the first rotating drive component, and the reamer's shank is mounted on the frame via a universal bearing, so that the reamer's shank can rotate around the universal bearing as the center, thereby making the reamer's shank flexible. When deburring deep holes, it can prevent the reamer's shank from getting stuck in the deep hole or bending in the deep hole.

[0011] In some embodiments, the coupling is a double-plate coupling.

[0012] In some embodiments, the frame includes a first subframe and a second subframe that are slidably connected, the universal bearing is disposed on the first subframe, and the first rotation drive member is disposed on the second subframe;

[0013] The flexible deburring device further includes a moving drive assembly, which is mounted on the first sub-frame and connected to the second sub-frame to drive the second sub-frame to move relative to the first sub-frame along the extension direction of the centerline of the reamer.

[0014] In some embodiments, the first sub-frame has a guide member that extends along the centerline of the reamer, and the second sub-frame is slidably connected to the guide member.

[0015] In some embodiments, there are multiple guide members, which are arranged at intervals around the centerline of the reamer.

[0016] In some embodiments, the motion drive assembly is a linear module having a base and a slide. The base is disposed on a first sub-frame, and the slide is movable relative to the base along the centerline extension direction of the reamer. The slide is disposed on a second sub-frame.

[0017] In some embodiments, the flexible deburring device further includes a first sensor and a second sensor, which are disposed on the first sub-frame and arranged at intervals along the centerline extension direction of the reamer. The first sensor is located on the side of the second sensor facing the cutter head.

[0018] The first sensor is electrically connected to both the motion drive assembly and the first rotation drive component. When the first sensor senses the second subframe, it sends a signal to both the motion drive assembly and the first rotation drive component, causing the motion drive assembly to move the second subframe relative to the first sensor in a direction toward the second sensor, and causing the first rotation drive component to rotate in the opposite direction.

[0019] The second sensor is electrically connected to the mobile drive assembly and the first rotation drive component, respectively, so as to send a signal to the mobile drive assembly and the first rotation drive component when the second sensor senses the second subframe, so as to stop the mobile drive assembly and the first rotation drive component.

[0020] In some embodiments, the slide is slidably connected to the base, and the linear module further includes a lead screw and a second rotation drive member. The second rotation drive member is connected to the lead screw to drive the lead screw to rotate about the axis of the lead screw. The lead screw is disposed on the base and is arranged along the center line extension direction of the reamer. The slide is disposed on the lead screw so that it can move relative to the base along the center line extension direction of the reamer under the drive of the lead screw.

[0021] In some embodiments, the linear module further includes a first speed reducer connected between the second rotary drive and the lead screw.

[0022] In some embodiments, the flexible deburring device further includes a second reducer connected between one end of the coupling and the first rotary drive member. Attached Figure Description

[0026] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] The following is a reference appendix. Figure 1 A flexible deburring device according to an embodiment of the invention is described.

[0028] like Figure 1 As shown, the flexible deburring device of this embodiment includes a frame 1, a first rotation drive 2, a coupling 3, a reamer 4, and a universal bearing 5. The first rotation drive 2 is mounted on the frame 1. One end of the coupling 3 is connected to the first rotation drive 2. The reamer 4 has a cutter head 41 and a cutter bar 42. The end of the cutter bar 42 away from the cutter head 41 is connected to the other end of the coupling 3. The universal bearing 5 is mounted on the frame 1, and the reamer 4 passes through the universal bearing 5.

[0029] like Figure 1As shown, the frame 1 includes a first subframe 11 and a second subframe 12. The first subframe 11 has an upper plate above the second subframe 12 and a base frame below the second subframe 12. The second subframe 12 is a plate. The reamer 4 extends vertically and has a cutter head 41 located above and a cutter shank 42 located below. The cutter head 41 is located above the upper plate. The cutter head 41 and the cutter shank 42 can be directly connected or connected through a universal joint to make the cutter head 41 flexible.

[0030] The first rotation drive 2 is connected to the second sub-frame 12 and located below the second sub-frame 12. The coupling 3 is located between the upper plate and the second sub-frame 12. The lower end of the coupling 3 is connected to the first rotation drive 2, and the upper end of the coupling 3 is connected to the lower end of the tool bar 42, so that the first rotation drive 2 can drive the reamer 4 to rotate around the center line of the reamer 4. Preferably, the first rotation drive 2 is a rotary motor.

[0031] The universal bearing 5 is embedded in the upper plate, and the middle part of the tool shank 42 passes through the universal bearing 5, so that the reamer 4 can rotate relative to the upper plate with the universal bearing 5 as the center under the action of the universal bearing 5. In other words, the extension direction of the center line of the reamer 4 can have an angle with the vertical direction. Preferably, the angle is less than 2°, and more preferably, the angle is less than 1°. When the reamer 4 forms an angle, the lower end of the tool shank 42 will have a small displacement in the horizontal and vertical directions. The coupling 3 plays a role in counteracting the displacement. Preferably, the coupling 3 is a double diaphragm coupling 3.

[0032] The flexible deburring device of this invention is equipped with a coupling to connect the reamer's shank to the first rotating drive component, and the reamer's shank is mounted on the frame via a universal bearing, so that the reamer's shank can rotate around the universal bearing as the center, thereby making the reamer's shank flexible. When deburring deep holes, it can prevent the reamer's shank from getting stuck in the deep hole or bending in the deep hole.

[0033] In some embodiments, the flexible deburring device of the present invention further includes a second reducer 9, which is connected between one end of the coupling 3 and the first rotation drive member 2.

[0034] like Figure 1 As shown, the second reducer 9 is located at the lower end of the second sub-frame 12. The lower end of the second reducer 9 is connected to the first rotating drive component 2, and the upper end of the second reducer 9 passes through the second sub-frame 12 and is connected to the lower end of the coupling 3.

[0035] It is understood that the flexible deburring equipment is not limited to having a second reducer; in other embodiments, the first rotary drive is directly connected to the coupling.

[0036] In some embodiments, the frame 1 includes a first sub-frame 11 and a second sub-frame 12 slidably connected, a universal bearing 5 is disposed on the first sub-frame 11, and a first rotation drive member 2 is disposed on the second sub-frame 12. The flexible deburring device of this embodiment further includes a moving drive assembly 6, which is disposed on the first sub-frame 11 and connected to the second sub-frame 12 to drive the second sub-frame 12 to move relative to the first sub-frame 11 along the extension direction of the centerline of the reamer 4.

[0037] like Figure 1 As shown, the moving drive assembly 6 is mounted on the first sub-frame 11 and extends in the vertical direction, so that the moving drive assembly 6 is connected to the upper plate and the base frame at the same time. Part of the moving drive assembly 6 is connected to the second sub-frame 12 to drive the second sub-frame 12 to move in the vertical direction between the upper plate and the base frame, so as to drive the reamer 4 and the first rotating drive member 2 in the vertical direction, so that the top of the reamer 4 can extend into the inner hole of the part to be deburred.

[0038] It is understood that the frame structure is not limited to including a slidingly connected first sub-frame and second sub-frame. In other embodiments, the frame is a fixed frame or base, in which case the flexible deburring device does not have a moving drive assembly, and the top of the reamer is inserted into the inner hole by moving the part to be deburred.

[0039] In some embodiments, the first subframe 11 has a guide 111, which is arranged along the centerline of the reamer 4, and the second subframe 12 is slidably connected to the guide 111.

[0040] In some embodiments, there are multiple guide members 111, which are arranged at intervals around the center line of the reamer 4.

[0041] like Figure 1 As shown, a guide member 111 is provided between the upper plate of the first subframe 11 and the base frame. The guide member 111 is preferably a guide rod extending in the vertical direction. There are preferably four guide rods, which are arranged at intervals around the center line of the reamer 4. The second subframe 12 is provided with four linear bearings, which are correspondingly sleeved on the four guide rods to allow the second subframe 12 to slide in the vertical direction on the guide rods. The guide member 111 serves to guide the second subframe 12 and connect and support the upper plate and the base frame.

[0042] It is understandable that the structure of the first and second subframes is not limited to... Figure 1 In some embodiments of the structure shown, the first subframe and the second subframe are two bases arranged sequentially in the left-right direction, and the first subframe and the second subframe are slidably connected by, for example, a slide rail so that the reamer can move in the up-down direction, in which case the guide is the slide rail.

[0043] In some embodiments, the motion drive assembly 6 is a linear module having a base and a slide 61. The base is mounted on a first sub-frame 11, and the slide 61 is movable relative to the base along the extension direction of the center line of the reamer 4. The slide 61 is mounted on a second sub-frame 12.

[0044] like Figure 1 As shown, the moving drive assembly 6 is a linear module. The linear module has a base and a slide 61. The base extends in the vertical direction and connects to the upper plate and the base frame. The slide 61 can move in the vertical direction relative to the base. The second sub-frame 12 is connected to the slide 61 so as to move in the vertical direction under the drive of the slide 61.

[0045] It is understood that the motion drive assembly is not limited to a linear module. In other embodiments, the motion drive assembly is a hydraulic or pneumatic telescopic component, such as a hydraulic cylinder or a pneumatic cylinder.

[0046] In some embodiments, the slide 61 is slidably connected to the base, and the linear module also has a lead screw 62 and a second rotation drive member 63. The second rotation drive member 63 is connected to the lead screw 62 to drive the lead screw 62 to rotate about the axis of the lead screw 62. The lead screw 62 is disposed on the base and is arranged along the center line extension direction of the reamer 4. The slide 61 is disposed on the lead screw 62 so that it can move relative to the base along the center line extension direction of the reamer 4 under the drive of the lead screw 62.

[0047] like Figure 1 As shown, the movable drive assembly 6 is preferably a ball screw type module, which also has a screw 62 and a second rotation drive 63. The screw 62 extends in the vertical direction, and the second rotation drive 63 is preferably a rotary motor. The slide 61 is connected to the base via a slide rail. The screw 62 is rotatably mounted on the base around its own axis, and the screw 62 passes through the slide 61 and is threadedly connected to the slide 61. When the screw 62 rotates around its own axis, under the threaded drive of the screw 62 and the guiding and limiting action of the slide rail, the slide 61 moves in the vertical direction. The second rotation drive 63 is mounted on the base frame of the first sub-frame 11 and is connected to the lower end of the screw 62 to drive the screw 62 to rotate around its own axis.

[0048] It is understood that the motion drive assembly is not limited to a ball screw type module; in other embodiments, the motion drive assembly is a synchronous belt type linear module.

[0049] In some embodiments, the linear module further includes a first reducer 64 connected between the second rotary drive 63 and the lead screw 62.

[0050] like Figure 1As shown, the first reducer 64 is mounted on the base frame of the first subframe 11. The upper end of the first reducer 64 is connected to the lead screw 62, and the lower end of the first reducer 64 is connected to the second rotary drive component 63.

[0051] It is understood that the linear module is not limited to having a first reducer; in other embodiments, the second rotary drive is directly connected to the lead screw.

[0052] In some embodiments, the flexible deburring device of the present invention further includes a first sensor 7 and a second sensor 8. The first sensor 7 and the second sensor 8 are disposed on the first sub-frame 11 and are arranged at intervals along the extension direction of the center line of the reamer 4. The first sensor 7 is located on the side of the second sensor 8 facing the cutter head 41. The first sensor 7 is electrically connected to the moving drive assembly 6 and the first rotating drive member 2 respectively, so that when the first sensor 7 senses the second sub-frame 12, it sends a signal to the moving drive assembly 6 and the first rotating drive member 2, causing the moving drive assembly 6 to drive the second sub-frame 12 to move relative to the first sensor 7 in the direction toward the second sensor 8, and causing the first rotating drive member 2 to rotate in the opposite direction. The second sensor 8 is electrically connected to the moving drive assembly 6 and the first rotating drive member 2 respectively, so that when the second sensor 8 senses the second sub-frame 12, it sends a signal to the moving drive assembly 6 and the first rotating drive member 2, causing the moving drive assembly 6 and the first rotating drive member 2 to stop.

[0053] like Figure 1 As shown, the frame 1 also has a sensor mounting bracket extending in the vertical direction. The lower end of the sensor mounting bracket is connected to the base frame, and the upper end of the sensor mounting bracket is connected to the upper plate. The first sensor 7 is disposed at the upper end of the sensor mounting bracket to sense the second sub-frame 12, and the first sensor 7 is electrically connected to the second rotation drive 63 and the first rotation drive 2 respectively. The second sensor 8 is disposed at the lower end of the sensor mounting bracket to sense the second sub-frame 12, and the second sensor 8 is electrically connected to the second rotation drive 63 and the first rotation drive 2 respectively.

[0054] During operation of the flexible deburring equipment, the second rotary drive 63 drives the second sub-frame 12 and the reamer 4 to move upwards to penetrate the inner hole of the component to be deburred, and the reamer 4 rotates clockwise. When the first sensor 7 senses the second sub-frame 12, the first sensor 7 sends a signal to the second rotary drive 63, causing the second rotary drive 63 to rotate in the opposite direction, driving the second sub-frame 12 and the reamer 4 to move downwards to extend out of the inner hole. At the same time, the first sensor 7 sends a signal to the first rotary drive 2, causing the first rotary drive 2 to rotate in the opposite direction, driving the reamer 4 to rotate in reverse. When the second sensor 8 senses the second sub-frame 12, the second sensor 8 simultaneously sends signals to both the second rotary drive 63 and the first rotary drive 2, causing the second rotary drive 63 and the first rotary drive 2 to stop, completing the deburring process for one inner hole.
