Description

Technical Field

[0001] This invention relates to the technical field of flange keyway processing equipment, specifically to a device for processing keyways on the inner wall of a connecting flange and its usage method. Background Technology

[0002] When machining the connecting flange, keyways are usually opened at the corresponding positions to enable torque transmission, prevent slippage, ensure coaxiality and centering accuracy, and achieve axial positioning or limiting to prevent the flange from moving axially and ensure stable assembly position.

[0003] Existing machining methods, such as milling, broaching, and cutting, often result in burrs on the inner wall or edge of the keyway after slotting the flange. These burrs are usually removed by manual grinding, which is inefficient for batch processing. Furthermore, uncontrollable factors such as manual experience and techniques lead to inconsistent deburring results.

[0004] In view of this, the present invention proposes a keyway processing device for the inner wall of a connecting flange and a method for using it, so as to solve the problems existing in the prior art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a keyway processing device for the inner wall of a connecting flange and its usage method.

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

[0007] A keyway processing device for connecting flange inner wall and its usage method, including a processing body and a tooling fixture, characterized in that a deburring mechanism is provided in the middle of the hollow tooling fixture, and the deburring mechanism is mounted on the output end of the displacement mechanism.

[0008] The deburring mechanism is a high-speed rotating wire brush used to flexibly deburr the inner surface of the flange keyway.

[0009] A displacement mechanism is provided in the middle of the hollow tooling fixture and is used to drive the deburring mechanism to perform deburring operations along the inner wall of the keyway.

[0010] Furthermore, the deburring mechanism includes a rotating shaft, the top end of which rotatably passes through a probe and is fixed to the output end of a first motor. The first motor is fixed to the top of the probe. The bottom end of the rotating shaft passes through a bearing ring and is rotatably and axially slidingly fitted.

[0012] Furthermore, the sleeve and the adjusting plate are connected by two sets of symmetrically arranged limiting blocks. The limiting blocks are arc-shaped and have connecting blocks fixedly attached to both ends. The outer end of the connecting block is fixedly attached to the inner wall of the adjusting plate. The inner side of the connecting block has a sliding hole, and a sliding shaft is slidably connected inside the sliding hole. The other end of the sliding shaft is fixedly attached to the outer wall of the sleeve. A first spring is sleeved on the outer side of the sliding shaft.

The upper end of the limiting strip is fixed to the bottom wall of the gear ring, the gear ring is rotatably connected to the top of the sleeve, the bottom end of the limiting strip is fixed to the top wall of the bottom ring, the bottom ring is rotatably connected to the bottom of the sleeve, an adjusting gear is meshed with one side of the gear ring, the central shaft of the adjusting gear rotates through the top cover and is fixed with an adjusting nut, the top cover is fixed to the top of the sleeve, and a first locking screw is threadedly connected to the side wall of the top cover corresponding to the position of the central shaft of the adjusting gear. The tail end of the first locking screw can abut against the central shaft of the adjusting gear.

[0014] Furthermore, one end of the probe is provided with a connecting end, which is inserted into the corresponding mounting slot of the square frame and fixed with screws. Reinforcing rods are symmetrically fixed on both sides of the probe, and the other end of the reinforcing rod is fixed to the top of the square frame with screws. A stabilizing bracket is fixed to one side of the bottom of the probe. The stabilizing bracket is a right-angled triangle with a retaining ring fixed to one vertical side. The retaining ring is slidably sleeved on the outer wall of the extension rod.

[0015] Furthermore, a centrifugal mechanism is provided at the top of the rotating shaft. The centrifugal mechanism includes a centrifugal disc with four symmetrically arranged sliding cavities at its center. A centrifugal sliding shaft is slidably engaged inside each sliding cavity. The outer end of the centrifugal sliding shaft slides through the centrifugal sliding shaft and is fixedly connected to the middle of the segmented centrifugal bar. A second spring is sleeved on the outer side of the centrifugal sliding shaft. The two ends of the second spring are respectively fixedly connected to the inner wall of the sliding cavity and the end edge fixed at one end of the centrifugal sliding shaft. The outer end face of the segmented centrifugal bar abuts against the outer end face of the abutment block.

[0016] Furthermore, the abutment block is fixed to the front side of the top of the cleaning scraper, and the cleaning scraper has symmetrically fixed end ears on both sides of the rear end of the top.

[0017] Furthermore, the displacement mechanism includes a cylinder, which is located in the middle of the hollow tooling fixture and fixedly connected to the working surface of the machining body. The top output end of the cylinder is rotatably connected to the bottom of the adapter end and locked and fixed by a second locking screw. The adapter end is laterally slidably connected to a support rod and locked and fixed by a third locking screw. One end of the support rod is fixedly mounted to a base plate by mounting screws. Slide rails are symmetrically fixed to both sides of the top of the base plate. A right-angle frame is slidably connected between the two slide rails.

The rotor has a Reichstag triangle structure, and the length of one side of the inner wall of the square frame is equal to the width of the rotor.

[0018] A method of using a keyway machining device for the inner wall of a connecting flange includes the following steps:

[0019] S1. After the main body of the machining process has finished slotting the keyway of the flange, the cylinder is started to drive the main body of the displacement mechanism and the deburring mechanism to move upward and make the working range cover the thickness of the keyway of the flange.

[0020] S2. Depending on the keyway size, the base plate and its upper connectors can be replaced as a whole to fit the keyway size by removing the screws on the reinforcing rod and the connecting end, as well as the mounting screws on the support rod end.

[0021] S3. Loosen the second and third locking screws, and then adjust the position of the support rod to match the deburring starting point of the keyway;

[0022] S4. Loosen the first locking screw and then turn the adjusting nut, which will drive the adjusting gear to rotate, which will drive the gear ring to rotate, which will drive the limiting strip and the bottom ring to rotate, which will change the contact position between the protruding top block and the limiting strip, and the limiting block will move outward under the action of the first spring, which will drive the adjusting plate to move outward, so that the metal wire outside the adjusting plate and the keyway are positioned to achieve a more suitable deburring distance. Then tighten the first locking screw to lock the adjusting nut.

[0023] S5. Start the first motor, and the rotating shaft drives the sleeve and the adjusting plate to rotate at high speed, thereby deburring the inner wall of the keyway.

[0024] S6. Start the second motor to drive the rotor to rotate. The rotor then drives the square frame to move within the slide rail and the right-angle frame and form a rectangular motion trajectory. This, in turn, drives the deburring mechanism to move along the inner wall of the keyway to complete the deburring operation.

[0025] S7. Start the linear motor to drive the extension rod to move up and down repeatedly, which in turn drives the connecting rod and bearing ring to move up and down repeatedly, which in turn drives the sleeve and adjusting plate to move up and down repeatedly, so as to achieve a better deburring effect.

[0026] S8. When the shaft rotates, it drives the centrifugal disc to rotate. At the same time, under the centrifugal action, the segmented centrifugal bars are thrown outward and abut against the abutment block, which moves backward. This causes the cleaning scraper to move backward, thus preventing the cleaning scraper from contacting the metal wire on the adjustment plate and reducing vibration. When the shaft stops rotating, the segmented centrifugal bars and the centrifugal sliding shaft retract under the pull of the second spring. Then, the third spring rebounds and drives the cleaning scraper forward. The toothed structure of the cleaning scraper scrapes against the metal wire on the adjustment plate, and self-cleaning is achieved by relying on the inertial tail speed of the shaft.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] The connecting flange inner wall keyway processing device and its usage method of the present invention, by setting the rotor motion trajectory characteristics and coordinating the limiting between the right angle frame, the square frame and the slide rail, makes the output path of the probe rod a rectangular trajectory, which can be adapted to conventional rectangular keyway scenarios. Moreover, the structure is only a sliding connection between each other, the structure is relatively simple, the later maintenance and replacement costs are low, and it has high application value.

[0029] The connecting flange inner wall keyway processing device and its usage method of the present invention, by setting a limiting block structure, can finely adjust the distance between the metal wire deburring head on the outer side of the adjustment plate and the inner wall of the keyway to ensure a better deburring effect when facing non-standard keyway sizes, thereby further improving the adaptability to keyway deburring.

[0030] The connecting flange inner wall keyway processing device and its usage method of the present invention can move the output end of the deburring mechanism up and down by adding a linear motor, thereby further improving the deburring effect.

[0031] The connecting flange inner wall keyway processing device and its usage method of the present invention, by setting a centrifugal mechanism and cooperating with a cleaning scraper and other structures, makes the cleaning scraper move away from the metal wires on the surface of the adjusting plate when the shaft rotates, thereby reducing vibration. At the same time, when the shaft stops rotating, the toothed structure of the cleaning scraper scrapes and abuts against the metal wires on the adjusting plate, and self-cleaning is achieved by relying on the inertial tail speed of the shaft.

Detailed Implementation

[0044] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0045] Please see Figure 1 This invention relates to a processing device for the keyway of the inner wall of a connecting flange and its method of use, comprising a processing body 10 and a hollow tooling fixture 70. The device is characterized in that a deburring mechanism 30 is provided in the middle of the hollow tooling fixture 70. The deburring mechanism 30 is mounted on the output end of a displacement mechanism 40. The deburring mechanism 30 is a high-speed rotating wire brush used for flexible deburring of the inner surface of the keyway 71 of the flange 70. The displacement mechanism 40 is located in the middle of the hollow tooling fixture 70 and is used to drive the deburring mechanism 30 to perform deburring operations along the inner wall of the keyway 71. It should be noted that the outer sides of both the displacement mechanism 40 and the transmission components of the deburring mechanism 30 are covered with protective shells to isolate the device structure from the corrosive effects of cutting debris.

[0046] Please see Figure 4-8The deburring mechanism 30 includes a rotating shaft 37. The top end of the rotating shaft 37 rotates through the probe rod 31 and is fixed to the output end of the first motor 38. The first motor 38 is fixed to the top of the probe rod 31. The bottom end of the rotating shaft 37 passes through the bearing ring 36 and can be rotatably engaged and axially slidingly engaged. A sleeve 39 is slidably sleeved on the outside of the rotating shaft 37. Multiple limit keys 3701 are fixed on the outside of the rotating shaft 37. The limit keys 3701 are slidably connected in the corresponding grooves of the sleeve 39. The sleeve 39 can move up and down while rotating with the rotating shaft, thereby completing the linkage between the subsequent structures driven by the linear motor. The outside of the sleeve 39 is provided with segmented adjustment plates 316. It should be noted that the gaps between the multiple adjustment plates 316 are provided with end bristles to prevent waste from entering the interior of the adjustment plates 316 and the sleeve 39. The outside of the adjustment plates 316 is covered with metal wires. The metal wires are made of a relatively soft material so that they can impact the burrs of the keyway through high-speed rotation to achieve the purpose of deburring.

[0047] Please see Figure 4 The top surface of the bearing ring 36 is rotatably engaged with the bottom of the sleeve 39. A connecting rod 35 is fixedly connected to one side of the bearing ring 36, and the other end of the connecting rod 35 is fixedly connected to the bottom of the extension rod 33. It should be noted that a baffle 34 is provided on one side of the extension rod 33. The top of the baffle is fixedly connected to the bottom of the probe rod 31 to prevent waste from corroding the extension rod 33 and other structures. The top of the extension rod 33 slides through the probe rod 31 and is fixedly connected to the output end of the linear motor 32. The linear motor 32 is fixedly connected to the top of the probe rod 31. The up-and-down reciprocating movement of the output end of the linear motor 32 can drive the bearing ring 36 to move up and down, thereby driving the sleeve 39 to move up and down.

[0048] Please see Figure 6-8 The sleeve 39 and the adjusting plate 316 are connected by two sets of symmetrically arranged limiting blocks 310. The limiting blocks 310 are arc-shaped and have connecting blocks 31001 fixedly attached to both ends. The outer end of the connecting block 31001 is fixedly attached to the inner wall of the adjusting plate 316. The inner side of the connecting block 31001 is provided with a sliding hole. A sliding shaft 31003 is slidably connected inside the sliding hole. The other end of the sliding shaft 31003 is fixedly attached to the outer wall of the sleeve 39. A first spring 31004 is sleeved on the outer side of the sliding shaft 31003. The two ends of the first spring 31004 are fixedly attached to the connecting block 31001 and the outer wall of the sleeve 39, respectively. A protruding top block 31002 is fixedly attached to the middle of the outer side of the limiting block 310. The free end of the protruding top block 31002 slides against the limiting strip 311.

[0049] Please see Figure 8The limiting strip 311 has a gradually widening arc-shaped cross-section. The upper end of the limiting strip 311 is fixed to the bottom wall of the gear ring 312, which is rotatably connected to the top of the sleeve 39. The bottom end of the limiting strip 311 is fixed to the top wall of the bottom ring 317, which is rotatably connected to the bottom of the sleeve 39. An adjusting gear 313 is meshed with one side of the gear ring 312. The central axis of the adjusting gear 313 rotates through the top cover 315 and is fixed with an adjusting nut 314. The top cover 315 is fixed to the top of the sleeve 39. A first locking screw 31401 is threaded onto the side wall of the top cover 315 corresponding to the position of the central axis of the adjusting gear 313. The tail of the first locking screw 31401... The end can abut against the central shaft of the adjusting gear 313. By loosening the first locking screw 31401 and then turning the adjusting nut 314, the adjusting gear 313 is driven to rotate, which in turn drives the gear ring 312 to rotate, which in turn drives the limiting strip 311 and the bottom ring to rotate. As a result, the position of the protruding top block 31002 abutting against the limiting strip 311 changes, and the limiting block 310 moves outward under the action of the first spring, which in turn drives the adjusting plate 316 to move outward, so that the metal wire outside the adjusting plate 316 and the keyway 71 are positioned to achieve a more suitable deburring distance. Then, the first locking screw 31401 is tightened to lock the adjusting nut 314.

[0050] Please see Figure 2 and 4 One end of the probe 31 is provided with a connecting end 3101, which is inserted into the corresponding mounting slot of the square frame 47 and fixed with screws. Reinforcing rods 3102 are symmetrically fixed on both sides of the probe 31. The other end of the reinforcing rod 3102 is fixed to the top of the square frame 47 with screws. A stabilizing bracket 3103 is fixed to one side of the bottom of the probe 31. The stabilizing bracket 3103 is a right triangle and a retaining ring 3104 is fixed to one vertical side. The retaining ring 3104 is slidably sleeved on the outer wall of the extension rod 33. The stability of the deburring output end is enhanced by setting the reinforcing rod 3102 and the stabilizing bracket 3103. At the same time, multiple sets of screws are connected to facilitate the disassembly and replacement of the displacement mechanism 40 body with different motion trajectories, further improving adaptability.

[0051] Please see Figure 6 and 9A centrifugal mechanism 50 is provided at the top of the rotating shaft 37. The centrifugal mechanism 50 includes a centrifugal disc 54. Four sliding cavities 541 are symmetrically opened in the center of the centrifugal disc 54. A centrifugal sliding shaft 52 is slidably engaged inside the sliding cavity 541. The outer end of the centrifugal sliding shaft 52 slides through the centrifugal sliding shaft 52 and is fixed to the middle of the segmented centrifugal bar 51. It should be noted that there are four segmented centrifugal bars 51 arranged at equal intervals, with two opposite bars being symmetrical and adjacent bars being staggered vertically. When the segmented centrifugal bars 51 reach the maximum centrifugal distance, the outer ends of the four segmented centrifugal bars 51... The surface will form a circular outline with equal radius to reduce the vibration of the segmented centrifugal bar 51 when it rotates and abuts against the abutting block 64, thereby improving the stability of the deburring output end. A second spring 53 is sleeved on the outside of the centrifugal slide shaft 52. The two ends of the second spring 53 are respectively fixed to the inner wall of the slide cavity 541 and the end edge 521 fixed at one end of the centrifugal slide shaft 52. The outer end face of the segmented centrifugal bar 51 abuts against the outer end face of the abutting block 64. It should be noted that a cover is provided on the top of the centrifugal mechanism 50 to prevent the cutting chips from eroding the structure of the device.

[0052] Please see Figure 5 and 10 The abutment block 64 is fixed to the front top of the cleaning scraper 60. The cleaning scraper 60 has symmetrically fixed end ears 61 on both sides of the rear top of the cleaning scraper 60. The end ears 61 are slidably engaged inside the limiting slide 62. The top of the limiting slide 62 is fixed to the bottom of the probe rod 31. The rear end face of the cleaning scraper 60 is fixed to one end of the third spring 63. The other end of the third spring 63 is fixed to the rear end wall of the limiting slide 62. The bottom end of the cleaning scraper 60 slides through the through hole opened in the connecting rod 35. One side of the cleaning scraper 60 has a toothed structure. The toothed structure scrapes and abuts against the metal wires arranged on the surface of the adjusting plate 316, which can clean the metal wires and improve the deburring effect in batches. It should be noted that the outer side of the limiting slide 62 is covered with a protective shell to isolate the cutting chips from the corrosion and other effects on the structure of this device.

[0053] Please see Figure 2-3The displacement mechanism 40 includes a cylinder 41, which is located in the middle of the hollow tooling fixture 70 and fixedly connected to the working surface of the machining body 10. The top output end of the cylinder 41 is rotatably connected to the bottom of the adapter end 42 and locked and fixed by a second locking screw 421. The adapter end 42 is laterally slidably connected to a support rod 43 and locked and fixed by a third locking screw 422. One end of the support rod 43 is fixedly mounted to a base plate 44 by a mounting screw 441. Slide rails 45 are symmetrically fixed to both sides of the top of the base plate 44. A right-angle frame 46 is slidably connected between the two slide rails 45. It should be noted that the right-angle frame 46 has an open end on one side. A square frame 47 is slidably connected inside the right-angle frame 46. It should be noted that one end of the probe rod 31 is connected to the right-angle frame corresponding to the square frame 47. At the open end of the frame 46, a rotor 48 is slidably abutted against inside the square frame 47. The eccentric shaft of the rotor 48 rotates through the base plate 44 and is fixed to the output end of the second motor 49. The second motor 49 is detachably embedded in the support rod 43. The rotor 48 has a Reichelk triangle structure. The length of one side of the inner wall of the square frame 47 is equal to the width of the rotor 48. Relying on the motion characteristics of the Reichelk triangle rotor 48, its width in each direction is the same. Relying on the eccentric shaft of the rotor 48, the rotor 48 slides against the inner wall of the square frame 47 when rotating, and drives the square frame 47 to move. With the limiting effect of the right-angle frame 46 and the slide rail 45, the motion trajectory of the square frame 47 can be limited to a rectangular path, thereby completing the deburring operation on the inner wall path of the keyway 71.

[0054] A method of using a keyway machining device for the inner wall of a connecting flange includes the following steps:

[0055] S1. After the keyway 71 of the processing body 10 to the flange 20 is slotted, the cylinder 41 is started to drive the displacement mechanism 40 body and the deburring mechanism 30 to move upward and make the working range cover the thickness of the keyway 71 of the flange 20.

[0056] S2. According to the size of the keyway 71, the base plate 44 and its upper connecting parts can be replaced as a whole to adapt to the size of the keyway 71 by removing the screws of the reinforcing rod 3102 and the connecting end 3101 and the mounting screws 441 of the end of the support rod 43.

[0057] S3. Loosen the second locking screw 421 and the third locking screw 422, and then adjust the position of the support rod 43 to match the deburring starting point of the keyway 71.

[0058] S4. Loosen the first locking screw 31401 and then turn the adjusting nut 314, which in turn drives the adjusting gear 313 to rotate, which in turn drives the gear ring 312 to rotate, which in turn drives the limiting strip 311 and the bottom ring to rotate, which in turn changes the contact position between the protruding top block 31002 and the limiting strip 311, which in turn causes the limiting block 310 to move outward under the action of the first spring 31004, which in turn drives the adjusting plate 316 to move outward, so that the metal wire outside the adjusting plate 316 and the keyway 71 are positioned to achieve a more suitable deburring distance. Then tighten the first locking screw 31401 to lock the adjusting nut 314.

[0059] S5. Start the first motor 38, and the rotating shaft 37 drives the sleeve 39 and the adjusting plate 316 to rotate at high speed, thereby deburring the inner wall of the keyway 71.

[0060] S6. Start the second motor 49 to drive the rotor 48 to rotate. Then the rotor 48 drives the square frame 47 to move within the slide rail 45 and the right-angle frame 46 and form a rectangular motion trajectory. Then the deburring mechanism 30 moves along the inner wall of the keyway 71 to complete the deburring operation.

[0061] S7. Start the linear motor 32, which drives the extension rod 33 to move up and down repeatedly, thereby driving the connecting rod 35 and the bearing ring 36 to move up and down repeatedly, thereby driving the sleeve 39 and the adjusting plate 316 to move up and down repeatedly, so as to achieve a better deburring effect.

[0062] S8. When the rotating shaft 37 rotates, it drives the centrifugal disc 54 to rotate. At the same time, under the centrifugal action, the segmented centrifugal bar 51 is thrown outward and abuts against the abutting block 64, which moves backward. This causes the cleaning scraper 60 to move backward, thus preventing the cleaning scraper 60 from contacting the metal wire on the adjusting plate 316 and reducing vibration. When the rotating shaft 37 stops rotating, the segmented centrifugal bar 51 and the centrifugal sliding shaft 52 retract under the pull of the second spring 53. Then, the third spring 63 rebounds and drives the cleaning scraper 60 to move forward. The toothed structure of the cleaning scraper 60 scrapes and abuts against the metal wire on the adjusting plate 316, and self-cleaning is achieved by relying on the inertial tail speed of the rotating shaft 37.

10. The method of using the keyway machining device for the inner wall of a connecting flange according to any one of claims 1-9, characterized in that, Includes the following steps: S1. After the processing body (10) finishes slotting the keyway (71) of the flange (20), start the cylinder (41) to drive the displacement mechanism (40) body and the deburring mechanism (30) to move upward and make the working range cover the thickness of the keyway (71) of the flange (20). S2. According to the keyway (71) size, the base plate (44) and its upper connector can be replaced as a whole to adapt to the keyway (71) size by removing the screws of the reinforcing rod (3102) and the connecting end (3101) and the mounting screws (441) of the support rod (43) end. S3. Loosen the second locking screw (421) and the third locking screw (422) to adjust the position of the support rod (43) to match the deburring starting point of the keyway (71); S4. Loosen the first locking screw (31401) and then turn the adjusting nut (314), which in turn drives the adjusting gear (313) to rotate, which in turn drives the gear ring (312) to rotate, which in turn drives the limiting strip (311) and the bottom ring to rotate, which in turn changes the contact position between the protruding top block (31002) and the limiting strip (311), which in turn causes the limiting block (310) to move outward under the action of the first spring (31004), which in turn drives the adjusting plate (316) to move outward, so that the metal wire outside the adjusting plate (316) and the keyway (71) are positioned to achieve a more suitable deburring distance. Then tighten the first locking screw (31401) to lock the adjusting nut (314). S5. Start the first motor (38), and the rotating shaft (37) drives the sleeve (39) and the adjusting plate (316) to rotate at high speed, thereby deburring the inner wall of the keyway (71); S6. Start the second motor (49) to drive the rotor (48) to rotate. Then the rotor (48) drives the square frame (47) to move in the slide rail (45) and the right angle frame (46) and form a rectangular motion trajectory. Then the deburring mechanism (30) moves along the inner wall of the keyway (71) to complete the deburring operation. S7. Start the linear motor (32) to drive the extension rod (33) to move up and down repeatedly, which in turn drives the connecting rod (35) and bearing ring (36) to move up and down repeatedly, which in turn drives the sleeve (39) and adjusting plate (316) to move up and down repeatedly, so as to achieve a better deburring effect. S8. When the rotating shaft (37) rotates, it drives the centrifugal disc (54) to rotate. At the same time, under the centrifugal action, the segmented centrifugal strip (51) is thrown outward and abuts against the abutting block (64) to move backward, thereby driving the cleaning scraper (60) to move backward, thereby preventing the cleaning scraper (60) from contacting the metal wire on the adjusting plate (316) and reducing vibration. When the rotating shaft (37) stops rotating, under the pull of the second spring (53), the segmented centrifugal strip (51) and the centrifugal sliding shaft (52) retract, and then the third spring (63) rebounds and drives the cleaning scraper (60) to move forward. Then the toothed structure of the cleaning scraper (60) scrapes against the metal wire on the adjusting plate (316), and self-cleaning is achieved by relying on the inertial tail speed of the rotating shaft (37).
