Technical Field
[0001] This utility model relates to the field of flange processing technology, and in particular to an integrated machine for flange drilling and chamfering. Background Technology
[0002] Currently, when machining the circumferential connection holes of a flange, the flange needs to be moved to one station first, positioned, and then the connection holes are drilled using a drilling machine. Then, the worker moves the flange to another station, positions it, and uses a chamfering machine to chamfer the connection holes. In this machining method, the worker needs to move the flange to another station to process the chamfer, which is labor-intensive. When the flange is moved to the second station, it needs to be repositioned, which affects the machining efficiency. Utility Model Content
[0003] To address the aforementioned shortcomings of existing flange connection hole processing methods, this invention proposes an integrated flange drilling and chamfering machine, which is more labor-saving and has higher processing efficiency.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A flange drilling and chamfering integrated machine includes a base, a chuck, a rotating mechanism, a drilling mechanism, a clutch mechanism, a lifting seat, and a drive mechanism. The chuck is rotatably connected to the upper side of the base and driven by the rotating mechanism. The chuck is used to position and lock the flange. The drilling mechanism includes a mounting base, a drill bit, and a return spring. The mounting base is located above the chuck and can move vertically. The return spring applies an upward pulling force to the mounting base for resetting it. The drill bit is mounted on the mounting base with the drill bit pointing downward. There are two sets of drilling mechanisms, named a drilling mechanism and a chamfering mechanism, respectively. The projections of the drill bits of the two drilling mechanisms on the flange are centrally symmetrical about the center of the flange. The drill bit of the drilling mechanism is equipped with a drill rod for drilling connecting holes, and the drill bit of the chamfering mechanism is equipped with a cutting tool for chamfering. The lifting seat is located between the mounting bases of the two drilling mechanisms. The clutch mechanism realizes the power disengagement between the lifting seat and the mounting base. The lifting seat moves vertically under the action of the drive mechanism.
[0005] Furthermore, the drilling mechanism also includes a fixing block fixedly connected to the side of the mounting base, and the clutch mechanism includes a clutch motor and a transmission plate. The transmission plate is horizontally rotatably connected to the lower side of the lifting base. The clutch mechanism includes a first state and a second state. In the first state, both ends of the transmission plate are located above the fixing blocks of the two sets of drilling mechanisms. In the second state, one end of the transmission plate moves away from the fixing block of the drilling mechanism, and the other end of the transmission plate is located above the fixing block of the chamfering mechanism. The clutch motor is used to drive the transmission plate to switch the state of the clutch mechanism.
[0006] Furthermore, the transmission plate includes a semicircular portion and a connecting portion fixedly connected to the center of the semicircular portion, the connecting portion being connected to the clutch motor.
[0007] Furthermore, the clutch mechanism also includes a support plate, which is fixedly connected to the side of the clutch motor, with the lower side of the support plate fitting against the upper side of the transmission plate.
[0008] Furthermore, the drilling mechanism also includes a guide rod, a fixing plate, and a guide sleeve. A side plate is fixedly connected to the upper side of the base. The guide sleeve is vertically positioned above the mounting base and is fixedly connected to the side plate via the fixing plate. The guide rod is vertically fixedly connected to the upper side of the mounting base. The guide rod passes through the guide sleeve and is slidably connected to the guide sleeve. A return spring is installed between the guide sleeve and the mounting base.
[0009] Furthermore, the drilling mechanism also includes a positioning block fixedly connected to the lower side of the fixed plate, with the lower side of the positioning block abutting against the mounting base.
[0010] Furthermore, the drilling rig can slide left and right on the mounting base, and the outer casing of the drilling rig is locked to the mounting base by fasteners.
[0011] Furthermore, the rotating mechanism is configured as a worm gear reducer and a servo motor, with the servo motor connected to the chuck via the worm gear reducer.
[0012] Through the above-mentioned technical improvements, the flange drilling and chamfering integrated machine of this utility model has the following beneficial effects: 1.

[0022] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0023] like Figures 1 to 9 This utility model proposes an integrated flange drilling and chamfering machine, which can perform even-numbered connecting holes and chamfers on a circular flange at equal intervals around its circumference in one workstation. Specifically, the integrated machine includes a base 3, a chuck 4, a rotating mechanism 5, a drilling mechanism, a clutch mechanism 6, a lifting seat 7, and a drive mechanism 8. The base 3 is fixed to the ground, and the chuck 4 is horizontally rotatably connected to the upper side of the base 3. The chuck 4 is a circular three-jaw chuck 4 for positioning and locking the circular flange 200. The rotating mechanism 5 can adopt a servo system and is connected to the center of the chuck 4, which can drive the chuck 4 to rotate. The drilling mechanism includes a mounting base 9, a drill 10, and a return spring 11. The mounting base 9 is set above the chuck 4 and can move vertically. The return spring 11 applies an upward pulling force to the mounting base 9 for resetting the mounting base 9. The drill 10 is mounted on the mounting base. 9. With the drill bit pointing downwards, the drilling mechanism is provided in two sets, left and right. The drilling mechanism on the left is named the drilling mechanism, and the drilling mechanism on the right is named the chamfering mechanism. The projections of the drill bits of the two drilling mechanisms on the flange are symmetrically arranged about the center of the flange. The drill bit of the drilling mechanism 10 is equipped with a drill rod 12 for drilling connecting holes, and the drill bit of the chamfering mechanism 10 is equipped with a cutting tool 13 for chamfering. The lifting seat 7 is located between the mounting seats 9 of the two drilling mechanisms. The power engagement and disengagement between the lifting seat 7 and the mounting seat 9 is realized through the clutch mechanism 6. That is, the clutch mechanism 6 can be poweredly engaged or disengaged from the mounting seat 9 of any drilling mechanism. The lifting seat 7 moves vertically under the action of the drive mechanism 8. The drive mechanism 8 can be a hydraulic mechanism or other mechanisms, without limitation.
[0024] In this embodiment, the working principle of the integrated machine is described using the example of machining eight connection holes on a flange. Figure 1The flange to be processed is locked on the chuck 4. The drilling mechanism and the chamfering mechanism are set on the left and right sides. Under the action of the return spring 11, the mounting seats 9 of the drilling mechanism and the chamfering mechanism maintain the same height. The drill rod 12 is located above the flange. The height difference between the lower end of the drill rod 12 and the lower end of the cutter 13 is h. The thickness of the flange is t, h>t. The mounting seat 9 of the drilling mechanism is poweredly engaged with the lifting seat 7 through the clutch mechanism 6. The mounting seat 9 of the chamfering mechanism is poweredly engaged with the lifting seat 7 through the clutch mechanism 6. When the drive mechanism 8 drives the lifting seat 7 to move downward, the lifting seat 7 drives the mounting seats 9 on the left and right sides to move downward. Figure 3 Drill rod 12 drills through the flange to form a connection hole, while the cutting tool 13 will not contact the flange and damage it. The chuck 4 has a clearance hole to avoid the drill rod 12, so the drill rod 12 will not interfere with the chuck 4 when drilling through the flange. The drive mechanism 8 drives the lifting seat 7 to move upwards, and the mounting seat 9 moves upwards with the lifting seat 7. The drill rod 12 moves upwards away from the flange. The rotating mechanism 5 drives the flange to rotate counterclockwise by 45 degrees. Thus, one connection hole is drilled on the flange. This process is repeated three times. Figure 4 Drill four connection holes on the flange, such as... Figure 5 and Figure 6 When drilling the fifth connecting hole, the first connecting hole is located just below the chamfering tool 13. Therefore, when the drive mechanism 8 drives the lifting seat 7 downward, after the drill rod 12 drills through the flange to form the fifth connecting hole, the drive mechanism 8 continues to drive the lifting seat 7 downward. The tool 13 then processes the chamfer of the first connecting hole. The drive mechanism 8 then drives the lifting seat 7 upward. After the drill rod 12 leaves the flange, the rotating mechanism 5 drives the flange to rotate 45 degrees counterclockwise. This process is repeated three times. Figure 7 All eight connecting holes have been machined, with four already chamfered. Four more require chamfering. During this process, each time drill rod 12 drills a new connecting hole, tool 13 simultaneously machines the opposite connecting hole. When the remaining four chamfers are being machined, the lifting seat 7 is disengaged from the drilling mechanism's mounting seat 9. Under the action of the return spring 11, the mounting seat 9 maintains its height, and the lower end of drill rod 12 does not contact the flange. The lifting seat 7 remains engaged with the chamfering mechanism's mounting seat 9. When the drive mechanism 8 drives the lifting seat 7 downwards, the chamfering mechanism's mounting seat 9 also moves downwards. Figure 8 After the cutting tool 13 moves downward with the mounting base 9 to process the chamfer, the drive mechanism 8 drives the lifting base 7 to move upward, and the rotating mechanism 5 drives the flange to rotate counterclockwise by 45 degrees. This process is repeated three times to complete all the chamfering. Figure 9 After chuck 4 loosens the flange, a new flange is replaced, and preparation for the next round of processing is made.
[0025] In one embodiment, such as Figure 1The drilling mechanism also includes a fixing block 14 fixedly connected to the side of the mounting base 9. The fixing block 14 of the drilling mechanism is fixedly connected to the right side of the corresponding mounting base 9, and the fixing block 14 of the chamfering mechanism is fixedly connected to the left side of the corresponding mounting base 9. The clutch mechanism 6 includes a clutch motor 61 and a transmission plate 62. The transmission plate 62 is horizontally rotatably connected to the lower side of the lifting base 7. The clutch mechanism 6 includes a first state and a second state, such as... Figure 1 In the first state, both ends of the transmission plate 62 are positioned above the fixing blocks 14 of the two drilling mechanisms, such as... Figure 8 In the second state, one end of the transmission plate 62 moves away from the fixed block 14 of the drilling mechanism, and the other end of the transmission plate 62 is located above the fixed block 14 of the chamfering mechanism. The clutch motor 61 is used to drive the transmission plate 62 to switch the state of the clutch mechanism 6.
[0026] In the first state, the left end of the transmission plate 62 is positioned above the fixed block 14 of the drilling mechanism to achieve power engagement between the lifting seat 7 and the mounting seat 9 of the drilling mechanism. The right end of the transmission plate 62 is positioned above the fixed block 14 of the drilling mechanism to achieve power engagement between the lifting seat 7 and the mounting seat 9 of the chamfering mechanism. When the drive mechanism 8 drives the lifting seat 7 to move downward, the lifting seat 7 pushes the mounting seats 9 on both sides to move downward synchronously through the transmission plate 62 and the fixed block 14, and the return spring 11 is stretched. When the drive mechanism 8 drives the lifting seat 7 to move upward, the return spring 11 contracts. Under the action of the return spring 11, the mounting seat 9 moves upward with the lifting seat 7, and the fixed block 14 maintains its engagement with the transmission plate 62. When the lifting seat 7 needs to be power-separated from the mounting seat 9 of the drilling mechanism, the clutch motor 61 drives the transmission plate 62 to rotate, and the left end of the transmission plate 62 moves away from the top of the mounting seat 9 on the left side, achieving power separation between the lifting seat 7 and the mounting seat 9 of the drilling mechanism. Figure 8 The right end of the transmission plate 62 is still located above the right mounting seat 9, realizing the power engagement between the lifting seat 7 and the mounting seat 9 of the chamfering mechanism. The left mounting seat 9 maintains its height under the action of the corresponding return spring 11. When the drive mechanism 8 drives the lifting seat 7 to move downward, the lifting seat 7 pushes the right mounting seat 9 downward through the transmission plate 62 for chamfering.
[0027] In one embodiment, such as Figure 2 The transmission plate 62 includes a semi-circular portion 621 and a connecting portion 622 fixedly connected to the center of the semi-circular portion 621. The connecting portion 622 is connected to the clutch motor 61. Figure 2 Define the left, right, and middle ends of the transmission plate 62, as follows: Figure 1When the left end of the transmission plate 62 abuts against the fixing block 14 of the left mounting seat 9, and the right end of the transmission plate 62 abuts against the fixing block 14 of the right mounting seat 9, the transmission plate 62 is in dynamic engagement with the mounting seats 9 on both sides. When the transmission plate 62 rotates 90 degrees counterclockwise around the center of the semicircle 621 under the action of the clutch motor 61, the left end of the transmission plate 62 separates from the fixing block 14 of the left mounting seat 9, and the middle end of the transmission plate 62 is still located above the fixing block 14 of the right mounting seat 9, thus realizing the dynamic engagement of the lifting seat 7 with the right mounting seat 9.
[0028] In one embodiment, such as Figure 1 The clutch mechanism 6 also includes a support plate 63, which is fixedly connected to the side of the clutch motor 61. The lower side of the support plate 63 is in contact with the upper side of the transmission plate 62 to improve the stability of the transmission plate 62.
[0029] In one embodiment, such as Figure 1 The drilling mechanism also includes a guide rod 15, a fixing plate 16, and a guide sleeve 17. A side plate 18 is fixedly connected to the upper side of the base 3. The guide sleeve 17 is vertically positioned above the mounting base 9 and is fixedly connected to the side plate 18 through the fixing plate 16. The guide rod 15 is vertically fixedly connected to the upper side of the mounting base 9. The guide rod 15 passes through the guide sleeve 17 and is slidably connected to the guide sleeve 17 to improve the vertical movement stability of the mounting base 9. A return spring 11 is installed between the guide sleeve 17 and the mounting base 9.
[0030] In one embodiment, such as Figure 1 The drilling mechanism also includes a positioning block 19 fixedly connected to the lower side of the fixed plate 16. The lower side of the positioning block 19 abuts against the mounting base 9, so that the mounting base 9 can move upward to a specified height under the action of the return spring 11, which facilitates the next power engagement between the lifting seat 7 and the mounting base 9.
[0031] In one embodiment, such as Figure 1 The mounting base 9 is fixedly connected with a guide rail 20 extending in the left and right directions. The drilling rig 10 can slide left and right along the guide rail 20 on the mounting base 9 to process flanges of different radii. The housing of the drilling rig 10 is locked to the mounting base 9 by fasteners 21 to fix the position of the drilling rig 10.
[0032] In one embodiment, such as Figure 1 The rotating mechanism 5 is configured with a worm gear reducer 51 and a servo motor 52. The servo motor 52 is connected to the chuck 4 through the worm gear reducer 51. The servo motor 52 can easily control the rotation angle to control the rotation angle between the chuck 4 and the flange. The worm gear reducer 51 has self-locking and deceleration effects, which further improves the rotation accuracy and the stability during processing.
[0033] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
