Description

Technical Field

[0001] This invention relates to the field of auxiliary components for machine tools, specifically to a chip removal device and method for chip removal via a threaded sleeve with a ferrule connection. Background Technology

[0002] With the rapid development of the manufacturing industry, various connectors have been produced. Among them, the threaded sleeve of the ferrule connection is a widely used connector. It has a stepped hole inside, that is, one end is a large through hole and the other end is a small diameter through hole. During processing, tapping is required.

[0003] During tapping, the tap enters through the large through hole, and the tapping debris needs to be discharged through the small through hole. However, since a plane (usually called the parting surface) is formed at the connection between the small through hole and the large through hole, some debris will fall onto the parting surface during the tapping process.

[0004] During processing, debris on the parting surface cannot be discharged through the small through-hole. Using air blowing is difficult to prevent debris from scattering everywhere. If the debris is spilled during the transfer of the sleeve after it is unclamped, all of the above methods can easily affect the working environment and are difficult to achieve the ideal processing effect. In response, some workers use magnets to attract and remove debris. However, with a certain magnetic force and a large amount of debris, it is difficult to ensure the thoroughness of the chip removal. Summary of the Invention

[0005] The purpose of this invention is to provide a chip removal device and method for opening holes in threaded sleeves with ferrule connections, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The threaded sleeve opening and chip removal device for ferrule connection includes a frame and an assembly plate movably mounted on the frame, and further includes:

[0008] A magnetic suction shaft is rotatably mounted on the assembly plate. The end of the magnetic suction shaft away from the assembly plate is connected to a feeding mechanism. The magnetic suction shaft can drive the feeding mechanism to rotate inside the sleeve. The debris accumulated on the parting surface is gathered towards the magnetic suction shaft by a gathering mechanism provided between the feeding mechanism and the magnetic suction shaft, so that the magnetic suction shaft can attract the debris.

[0009] An intermittent drive mechanism is installed on the assembly plate and connected to the magnetic suction shaft. The intermittent drive mechanism can drive the ejector mechanism to reciprocate along the axial direction of the magnetic suction shaft to perform a lifting action on the debris attached to the outer wall of the magnetic suction shaft. The stroke of the ejector mechanism gradually decreases so that the debris on the parting surface is dispersed on the outer wall of the magnetic suction shaft.

[0010] As a further aspect of the present invention: a drive motor is mounted on the assembly plate, the output end of the drive motor is connected to the magnetic suction shaft, and the ejector mechanism includes a tube slidably disposed at one end of the magnetic suction shaft;

[0011] The tubular component and the magnetic suction shaft are sealed and slidably fitted together. A concave-convex transmission structure is provided between the magnetic suction shaft and the tubular component, and the tubular component is connected to the intermittent drive mechanism through a ring transmission structure.

[0012] As a further embodiment of the present invention: the concave-convex transmission structure includes two strip-shaped protrusions formed on the outer wall of the magnetic suction shaft and two strip-shaped grooves provided on the inner wall of the tube, wherein the strip-shaped grooves are adapted to the strip-shaped protrusions.

[0013] As a further embodiment of the present invention: the converging mechanism includes a cleaning component disposed on the magnetic suction shaft via a connecting column and a protrusion formed on one end of the tube near the drive motor. A gap is reserved between the cleaning component and the outer wall of the magnetic suction shaft. The protrusion is adapted to the gap and is located within the gap, and is sealed and slidably fitted with the cleaning component and the outer wall of the magnetic suction shaft, so that the protrusion and the cleaning component form a pusher arm for sweeping debris on the parting surface inside the sleeve.

[0014] As a further embodiment of the present invention: the ring transmission structure includes two columns slidably disposed on the assembly plate, a ring body connected to the two columns, and two connecting rods installed on the pipe.

[0015] The column is connected to the intermittent drive mechanism at the end away from the ring body, and the ring body is provided with an annular guide groove. Two transmission blocks are slidably fitted in the annular guide groove, and the two connecting rods are respectively fixed to the two transmission blocks.

[0016] As a further embodiment of the present invention: the intermittent drive mechanism includes a circumferential rotation component mounted on the assembly plate and connected to the magnetic suction shaft, and an elastic driven component connected to the two columns, wherein the circumferential rotation component cooperates with the elastic driven component.

[0017] As a further embodiment of the present invention: the circumferential rotating assembly includes a rotating shaft rotatably mounted on the assembly plate, a rotating plate disposed on the rotating shaft, and a pulley disposed at one end of the rotating plate away from the rotating shaft;

[0018] The bottom of the assembly plate is rotatably mounted with a second gear, which meshes with a first gear disposed on the magnetic shaft. The rotating shaft of the second gear is connected to the rotating shaft via a first transmission belt.

[0019] As a further embodiment of the present invention: the assembly plate is provided with two protruding blocks, and the elastic driven component includes two crossbars that are slidably disposed on the two protruding blocks respectively, a connecting plate connecting the ends of the two crossbars, and a driven plate that is movably disposed on the connecting plate. The driven plate is provided with an inclined surface that cooperates with the pulley, and the driven plate is connected to a position adjustment structure installed on the assembly plate.

[0020] Each of the two crossbars is also hinged to a connecting rod at its tail end. The ends of the two connecting rods away from the crossbars are respectively hinged to the two columns. A cylindrical spring is also sleeved on the outer periphery of the crossbars. The two ends of the cylindrical spring are respectively connected to the protruding block and the connecting plate.

[0021] As a further embodiment of the present invention: the connecting plate is provided with a guide groove, the position adjustment structure includes a slider that is slidably fitted in the guide groove and a lead screw that is rotatably mounted on the assembly plate, two push plates are slidably provided on the connecting plate, the first end of the push plate is fixed to the driven plate, and the other end is provided with a transmission plate, the transmission plate is provided with an inclined through groove, and a drive column connected to the slider is slidably provided in the inclined through groove;

[0022] The lead screw is fitted with a threaded sleeve that is threadedly connected to the lead screw, and the threaded sleeve is provided with a guide plate that is slidably connected to the slider. The lead screw is connected to a third gear that is rotatably mounted on the assembly plate through a bevel gear set and a second transmission belt. The third gear cooperates with an arc-shaped toothed plate fixed on the rotating shaft.

[0023] The chip removal method for threaded sleeves with ferrule connections, using the aforementioned chip removal device, includes the following steps:

[0024] Step 1: Power on the magnetic suction shaft. The magnetic suction shaft and the ejector mechanism will move horizontally on the frame to the position aligned with the sleeve, and then move up and down on the frame to enter the inside of the sleeve.

[0025] Step 2: The magnetic suction shaft and the gathering mechanism rotate inside the sleeve. The gathering mechanism gathers the debris on the parting surface inside the sleeve toward the outer wall of the magnetic suction shaft, and the magnetic suction shaft attracts the debris.

[0026] Step 3: The intermittent drive mechanism drives the top material mechanism to reciprocate along the axial direction of the magnetic suction shaft, lifting the debris adsorbed on the outer wall of the magnetic suction shaft upward.

[0027] Step 4: The reciprocating stroke of the ejector mechanism gradually decreases, causing the debris on the parting surface to disperse on the outer wall of the magnetic suction shaft.

[0028] Step 5: The magnetic suction shaft and the ejector mechanism are pulled out and reset from the sleeve. The magnetic suction shaft is de-energized, and the falling debris is collected.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention has a novel design. In specific implementation, the collecting mechanism gathers the debris on the parting surface to the magnetic suction shaft. The magnetic suction shaft is used to adsorb the debris, and the intermittent driving mechanism can drive the ejecting mechanism to lift the debris adsorbed on the magnetic suction shaft upward. The height of each lift gradually decreases, so the debris eventually forms a thin layer on the outer periphery of the magnetic suction shaft, ensuring the firmness of the magnetic suction shaft's attraction to the debris. This avoids the problem of insufficient adsorption force due to thick debris on the outer periphery of the magnetic suction shaft, which could lead to accidental detachment. Therefore, when there is a lot of debris in the sleeve, it can prevent the problem of incomplete chip removal due to insufficient attraction of the magnetic suction shaft. Through the cooperation between various mechanisms and components, the effective removal function of debris in the sleeve is achieved, with good chip removal effect, high degree of automation, and suitability for widespread use.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Furthermore, elements in this invention are referred to as being "disposed on" or "located on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0041] Please see Figures 1-8 In this embodiment of the invention, the threaded sleeve opening chip removal device for ferrule connection includes a frame and an assembly plate 3 movably mounted on the frame.

[0042] The threaded sleeve opening chip removal device of the ferrule connection also includes a magnetic suction shaft 4 rotatably mounted on the assembly plate 3. The end of the magnetic suction shaft 4 away from the assembly plate 3 is connected to a material ejector mechanism. The magnetic suction shaft 4 can drive the material ejector mechanism to rotate inside the sleeve, and the debris accumulated on the parting surface is gathered to the magnetic suction shaft 4 by a gathering mechanism provided between the material ejector mechanism and the magnetic suction shaft 4, so that the magnetic suction shaft 4 attracts the debris. The frame includes two supports 1 and a crossbeam 2 slidably disposed between the two supports 1. The crossbeam 2 can slide up and down on the supports 1 (driven by a cylinder). The assembly plate 3 is slidably disposed on the crossbeam 2 and can slide along the length of the crossbeam 2 (driven by another cylinder). Specifically, this device can be used in conjunction with a tapping device. After the tapping device completes tapping, the assembly plate 3 slides along the length of the crossbeam 2 until the magnetic suction shaft 4 is coaxial with the sleeve. Subsequently, the crossbeam 2 slides downward on the supports 1 until the magnetic suction shaft 4 and the ejector mechanism enter the sleeve. The chip removal principle of this device is to energize the magnetic suction shaft 4, causing it to become magnetic, thereby attracting chips on the parting surface inside the sleeve.

[0043] The assembly plate 3 is also equipped with an intermittent drive mechanism connected to the magnetic suction shaft 4. The intermittent drive mechanism can drive the ejector mechanism to reciprocate along the axial direction of the magnetic suction shaft 4 to perform a lifting action on the debris attached to the outer wall of the magnetic suction shaft 4. The stroke of the ejector mechanism gradually decreases so that the debris on the parting surface is dispersed on the outer wall of the magnetic suction shaft 4.

[0044] During the chip removal process, the magnetic suction shaft 4 drives the ejector mechanism and the gathering mechanism to rotate inside the sleeve. The gathering structure gathers the chips on the parting surface inside the sleeve towards the magnetic suction shaft 4, thus attracting the chips. During this process, the intermittent drive mechanism can intermittently drive the ejector mechanism to reciprocate along the axial direction of the magnetic suction shaft 4, and the stroke of the ejector mechanism gradually decreases. Therefore, after several reciprocations, the chips on the parting surface will be more evenly distributed on the outer wall of the magnetic suction shaft 4. Finally, the magnetic suction shaft 4 is driven to be pulled out of the sleeve, the power to the magnetic suction shaft 4 is turned off, and the chips on its outer periphery are recycled.

[0045] In summary, during implementation, the collecting mechanism gathers the debris from the parting surface towards the magnetic suction shaft 4. The magnetic suction shaft 4 utilizes its adsorption properties to attract the debris. The intermittent driving mechanism drives the ejector mechanism to lift the debris adsorbed on the magnetic suction shaft 4 upwards, with the lifting height gradually decreasing each time. Therefore, the debris eventually forms a thin layer on the outer periphery of the magnetic suction shaft 4, ensuring the strong attraction of the magnetic suction shaft 4 to the debris and preventing insufficient adsorption due to a thicker layer of debris on the outer periphery of the magnetic suction shaft 4, which could lead to accidental detachment. Thus, when there is a large amount of debris inside the sleeve, it can prevent incomplete chip removal due to insufficient attraction of the magnetic suction shaft 4. Through the cooperation between various mechanisms and components, the effective removal of debris from the sleeve is achieved, with good chip removal performance, a high degree of automation, and suitability for widespread use.

[0046] In detail, when the magnetic attraction of the magnetic shaft 4 is constant, if the debris is attracted by the fixed part of the magnetic shaft 4, the debris will gradually thicken on the outer periphery of the magnetic shaft 4. Correspondingly, the magnetic shaft 4's attraction to other debris will be reduced. Therefore, when there is a lot of debris, it is difficult to ensure the thoroughness of chip removal unless it is done in multiple stages, but this will affect the work efficiency. Therefore, this application sets up the top material mechanism and uses its gradually decreasing stroke to perform layered processing on the adsorbed debris, so that the debris is more evenly distributed on the outer periphery of the magnetic shaft 4, thus effectively ensuring the reliable chip removal.

[0047] Please refer to it again. Figure 5 and Figure 6 A drive motor 8 is mounted on the assembly plate 3, and the output end of the drive motor 8 is connected to the magnetic suction shaft 4. The ejector mechanism includes a tube 5 slidably disposed at one end of the magnetic suction shaft 4. The tube 5 is sealed and slidably fitted with the magnetic suction shaft 4, and a concave-convex transmission structure is provided between the magnetic suction shaft 4 and the tube 5. The tube 5 is connected to the intermittent drive mechanism through a ring transmission structure. The concave-convex transmission structure includes two strip-shaped protrusions 401 formed on the outer wall of the magnetic suction shaft 4 and two strip-shaped grooves 501 provided on the inner wall of the tube 5. The strip-shaped grooves 501 are adapted to the strip-shaped protrusions 401.

[0048] During operation, the drive motor 8 operates, driving the magnetic suction shaft 4 to rotate. The magnetic suction shaft 4 then drives the tube 5 to rotate via the strip-shaped protrusion 401 and the strip-shaped groove 501. This allows the tube 5 to rotate synchronously with the magnetic suction shaft 4, enabling the converging mechanism to gather debris from the inner parting surface of the sleeve towards the outer periphery of the magnetic suction shaft 4. Furthermore, the arrangement of the strip-shaped protrusion 401 and the strip-shaped groove 501 allows the intermittent drive mechanism to drive the tube 5 to slide along the axial direction of the magnetic suction shaft 4 via the annular transmission structure during synchronous rotation with the magnetic suction shaft 4, thereby lifting the debris attached to the outer wall of the magnetic suction shaft 4 upwards.

[0049] The converging mechanism includes a cleaning component 10 mounted on the magnetic suction shaft 4 via a connecting post 9 and a protrusion 502 formed on one end of the tube 5 near the drive motor 8. A gap is reserved between the cleaning component 10 and the outer wall of the magnetic suction shaft 4. The protrusion 502 is adapted to the gap and is located within the gap. It is also sealed and slidably fitted with the cleaning component 10 and the outer wall of the magnetic suction shaft 4, so that the protrusion 502 and the cleaning component 10 form a pusher arm for sweeping debris on the parting surface inside the sleeve.

[0050] In detail, the surface formed by the pusher arm is parallel to the central axis of the magnetic suction shaft 4, and the length of the cleaning component 10 is equal to the annular diameter of the parting surface inside the sleeve. The tube 5 is adapted to the small through hole inside the sleeve. Therefore, during operation, the crossbeam 2 descends, the tube 5 enters the small through hole of the sleeve, the cleaning component 10 abuts against the parting surface inside the sleeve, and the drive motor 8 operates, which drives the magnetic suction shaft 4 and the tube 5 to rotate. The pusher arm then makes a circular motion inside the sleeve, and the debris on the parting surface inside the sleeve will gradually move towards the outer wall of the magnetic suction shaft 4 under the action of the pusher arm, so that the magnetic suction shaft 4 can attract the debris.

[0051] Please refer to it again. Figure 6 The annular transmission structure includes two columns 14 slidably mounted on the assembly plate 3, an annular body 11 connected to the two columns 14, and two connecting rods 13 mounted on the pipe 5. The end of each column 14 away from the annular body 11 is connected to the intermittent drive mechanism, and the annular body 11 is provided with an annular guide groove. Two transmission blocks 12 are slidably fitted into the annular guide groove, and the two connecting rods 13 are respectively fixed to the two transmission blocks 12.

[0052] Furthermore, the central axis of the ring 11 coincides with that of the magnetic shaft 4. When the tube 5 rotates, it will drive the transmission block 12 to slide circumferentially on the ring 11 through the connecting rod 13. When the intermittent drive mechanism moves, it will drive the two columns 14 to slide up and down on the assembly plate 3. Correspondingly, the columns 14 can drive the tube 5 to slide up and down on the magnetic shaft 4 through the ring 11, the transmission block 12 and the connecting rod 13, so that the rotation and up and down movement of the tube 5 do not interfere with each other.

[0053] Please refer to it again. Figure 4 , Figure 5 as well as Figure 7 The intermittent drive mechanism includes a circumferential rotating assembly mounted on the assembly plate 3 and connected to the magnetic suction shaft 4, and an elastic driven assembly connected to the two columns 14, wherein the circumferential rotating assembly cooperates with the elastic driven assembly. The circumferential rotating assembly includes a rotating shaft 28 rotatably mounted on the assembly plate 3, a rotating plate 29 disposed on the rotating shaft 28, and a pulley 2901 located at one end of the rotating plate 29 away from the rotating shaft 28. A second gear 7 is also rotatably mounted on the bottom of the assembly plate 3, and the second gear 7 meshes with a first gear 6 disposed on the magnetic suction shaft 4. The rotating shaft of the second gear 7 is connected to the rotating shaft 28 via a first transmission belt 26.

[0054] Please refer to it again. Figure 4 and Figure 8 The assembly plate 3 has two protruding blocks 301. The elastic driven assembly includes two crossbars 16 slidably mounted on the two protruding blocks 301, a connecting plate 18 connecting the ends of the two crossbars 16, and a driven plate 22 movably mounted on the connecting plate 18. The driven plate 22 has an inclined surface 2201 that cooperates with the pulley 2901. The driven plate 22 is connected to a position adjustment structure mounted on the assembly plate 3. Each of the two crossbars 16 has a connecting rod 15 hinged to its tail end. The ends of the two connecting rods 15 away from the crossbars 16 are respectively hinged to the two columns 14. A cylindrical spring 17 is also sleeved on the outer periphery of the crossbars 16. The two ends of the cylindrical spring 17 are respectively connected to the protruding blocks 301 and the connecting plate 18.

[0055] While the drive motor 8 drives the magnetic shaft 4 to rotate, the magnetic shaft 4 drives the rotating shaft 28 to rotate via the first gear 6, the second gear 7, and the first transmission belt 26. Consequently, the rotating plate 29 drives the pulley 2901 to perform circular motion on the assembly plate 3. When the pulley 2901 acts on the inclined surface 2201, it causes the driven plate 22 to move aside. Thus, the driven plate 22 drives the connecting plate 18 to move closer to the protruding block 301. When the cylindrical spring 17 is compressed, the crossbar 16 pushes the column 14 to slide upward on the assembly plate 3 via the connecting rod 15. After the pulley 2901 separates from the driven plate 22, the cylindrical spring 17 rebounds, and the crossbar 16 pulls the column 14 to slide upward and reset on the assembly plate 3 via the connecting rod 15. Correspondingly, the tube 5 completes one reciprocating slide along the axial direction of the magnetic shaft 4, lifting the debris adsorbed on the outer wall of the magnetic shaft 4 upward.

[0056] The connecting plate 18 is provided with a guide groove 1801. The position adjustment structure includes a slider 19 that is slidably fitted in the guide groove 1801 and a lead screw 23 that is rotatably mounted on the assembly plate 3. Two push plates 20 are slidably provided on the connecting plate 18. The first end of the push plate 20 is fixed to the driven plate 22, and the other end is provided with a transmission plate 21. The transmission plate 21 is provided with an inclined through groove 2101. A drive column 1901 connected to the slider 19 is slidably provided in the inclined through groove 2101. A threaded sleeve 24 that is threadedly connected to the lead screw 23 is sleeved on the lead screw 23. A guide plate 25 that is slidably connected to the slider 19 is provided on the threaded sleeve 24. The lead screw 23 is connected to a third gear 31 that is rotatably mounted on the assembly plate 3 through a bevel gear set 32 ​​and a second transmission belt 27. The third gear 31 cooperates with an arc-shaped toothed plate 30 fixed on the rotating shaft 28.

[0057] In detail, the bevel gear set 32 ​​includes a first bevel gear rotatably mounted on the assembly plate 3 and a second bevel gear mounted on the lead screw 23, and the second bevel gear meshes with the first bevel gear. The second transmission belt 27 is used to connect the rotation shafts of the first bevel gear and the third gear 31.

[0058] Whenever the pulley 2901 disengages from the driven plate 22 (during the process of the pulley 2901 acting on the inclined surface 2201, the slider 19 slides along the guide plate 25), the arc-shaped toothed plate 30 meshes with the third gear 31, thus causing the third gear 31 to rotate. The rotation shaft of the third gear 31 then drives the lead screw 23 to rotate through the second transmission belt 27 and the bevel gear set 32. The threaded sleeve 24 engages with the lead screw 23 and moves away from the bevel gear set 32. Correspondingly, the threaded sleeve 24 drives the slider 19 to slide within the guide groove 1801 through the guide plate 25. The moving column 1901 slides with the transmission plate 21 through the inclined through groove 2101, causing the transmission plate 21 to move. That is, the transmission plate 21 drives the driven plate 22 to move closer to the drive motor 8 through the two push plates 20. This cycle continues. Before the pulley 2901 acts on the inclined surface 2201, the distance between the driven plate 22 and the drive motor 8 becomes shorter and shorter. That is, for every rotation of the pulley 2901, the reciprocating stroke of the driven plate 22 (i.e. the tube 5) gradually decreases, so that the tube 5 has the characteristic of progressively pushing the material, so that the debris can be distributed more evenly on the outer periphery of the magnetic suction shaft 4.

[0059] As another embodiment of the present invention, a method for chip removal from the opening of a threaded sleeve in a ferrule connection is also proposed, which uses the aforementioned chip removal device and includes the following steps:

[0060] Step 1: Power on the magnetic suction shaft 4. The magnetic suction shaft 4 and the ejector mechanism will move horizontally on the frame to the position aligned with the sleeve, and then move up and down on the frame to enter the inside of the sleeve.

[0061] Step 2: The magnetic suction shaft 4 and the gathering mechanism rotate inside the sleeve. The gathering mechanism gathers the debris on the parting surface inside the sleeve toward the outer wall of the magnetic suction shaft 4, and the magnetic suction shaft 4 attracts the debris.

[0062] Step 3: The intermittent drive mechanism drives the top material mechanism to reciprocate along the axial direction of the magnetic suction shaft 4, lifting the debris adsorbed on the outer wall of the magnetic suction shaft 4 upward.

[0063] Step 4: The reciprocating motion of the ejector mechanism gradually decreases, causing the debris on the parting surface to disperse on the outer wall of the magnetic suction shaft 4.

[0064] Step 5: The magnetic suction shaft 4 and the ejector mechanism are pulled out and reset from the sleeve. The magnetic suction shaft 4 is de-energized, and the falling debris is collected.
