[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figure 1-8 , the present invention provides a technical solution:

[0037] A drilling device for flange production includes a platform 1 and multiple drilling components. The drilling components include a connecting frame 3 fixedly connected to the top surface of a connecting column 206. The connecting frame 3 is C-shaped. A lifting cylinder 4 is fixedly connected to the top end of the connecting frame 3. A telescopic rod 401 is arranged below the lifting cylinder 4, and a drilling rig 402 is arranged on the telescopic rod 401.

[0038] The front of the platform 1 is rotatably connected to a cabinet door, and a control panel 101 is installed on the right side of the platform 1 through a tripod. By setting the control panel 101, the staff can quickly and conveniently operate various electric and pneumatic components in the platform 1. A maintenance cabinet 102 is set below the platform 1, and tools for maintenance and parts for replacement are stored in the maintenance cabinet 102. By setting the maintenance cabinet 102, when the staff needs to repair and replace the device in the platform 1, it is more convenient to find tools and parts.

[0039] The drilling assembly is connected to the table body 1 through an adjusting assembly 2, which includes a driving disk 201 rotatably connected to the left side of the top surface of the table body 1, and a driven disk 202 rotatably connected to the middle of the top surface of the table body 1. The driving disk 201 is engaged with the driven disk 202, and a guide groove 203 is provided on the top surface of the driven disk 202. A limiting groove 204 staggered with the guide groove 203 is provided on the top surface of the table body 1. A limiting block 205 is slidably connected in the limiting groove 204, and a connecting column 206 is provided on the top surface of the limiting block 205. The connecting column 206 is fixedly connected to the bottom surface of the drilling assembly.

[0040] The guide groove 203 passes through to the bottom surface of the driven disk 202, and the limit groove 204 is arranged inside the table body 1 and passes through the top surface of the table body 1. The guide groove 203 is inclined, and the limit groove 204 is vertically opened. The limit groove 204 is a convex groove, and the limit block 205 is a convex block adapted thereto. A connecting column 206 is fixedly connected to the center of the top surface of the limit block 205, and the connecting column 206 passes through the intersection of the guide groove 203 and the limit groove 204 and is fixedly connected to the bottom surface of the drilling assembly. The connecting column 206 is a cylinder. There are multiple guide grooves 203 and limit grooves 204, and their numbers correspond to each other. They are arranged in a circular array at equal intervals on the top surface of the driven disk 202 and the top surface of the table body 1. During production design, the number of guide grooves 203 and limit grooves 204 can be adjusted according to the number and position of holes punched in the flange.

[0041] By adopting the above design, when it is necessary to adjust the position of the drilling assembly on the top of the connecting column 206, the driven disk 202 can be driven to rotate by rotating the driving disk 201, thereby changing the staggered position of the guide groove 203 and the limiting groove 204. At this time, the connecting column 206 is limited by the limiting block 205 fixedly connected to it and can only slide along the opening direction of the limiting groove 204, so that when the connecting column 206 is pressed and moved by the side wall of the guide groove 203, the rotating force is converted into the carrier limiting block 205 and moves along the opening direction of the limiting groove 204. The moving force causes the connecting column 206 to be pushed along the opening direction of the limiting groove 204 after the driven disk 202 rotates, and since the limiting groove 204 is opened vertically, the connecting column 206 moves vertically, and the drilling components fixedly connected on the top of the multiple connecting columns 206 move toward or away from the center of the driven disk 202 in a straight line. In this way, the positions of the multiple drilling components are synchronously controlled by a single driving source, making the adjustment process more convenient and reducing the occurrence of errors in the drilling position due to mistakes caused by repeated operations.

[0042] Further, refer to Figure 2 and Figure 3As shown, the side of the driven disk 202 is provided with teeth with a size of one twelfth of its outer diameter, and the range of the teeth is the same as the angle that the driven disk 202 needs to rotate when the limit block 205 slides from one end of the limit slot 204 to the other end of the limit slot 204. The driven disk 202 is meshed with the driving disk 201 through the teeth, and the top surface of the driving disk 201 is provided with a turning handle 207, and the turning handle 207 is rotatably connected with an anti-skid sleeve. By providing the turning handle 207, the staff can apply force by holding the turning handle 207 when rotating the driving disk 201. Compared with the smooth top surface and the side wall covered with teeth of the driving disk 201, the turning handle 207 is more comfortable to hold and more convenient to apply force. In addition, the turning handle 207 is rotatably connected with an anti-skid sleeve. By providing the anti-skid sleeve, when the staff rotates the driving disk 201, there is no need to loosen the grip back and forth due to multiple rotations, and adjust the angle of the palm when holding.

[0043] In addition, a clamping sleeve can be horizontally set on the platform 1 on one side of the driving disk 201, and a clamping block can be set on the clamping sleeve so that it can only slide horizontally. A clamping spring is set between the clamping block and the clamping sleeve, and teeth that engage with the driving disk 201 are set on the clamping block, so that the clamping block is engaged with the driving disk 201 under normal conditions to prevent the driving disk 201 from rotating during the processing and causing the drilling assembly to move. When the position of the drilling assembly needs to be adjusted, the clamping block is pressed until it disengages from the driving disk 201, and the driving disk 201 can be rotated.

[0044] The present invention provides another technical solution:

[0045] See also Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 The drilling assembly is also provided with a head changing assembly, which includes a coil 403 fixedly connected to the output shaft of the drilling machine 402, an electromagnet 404 fixedly connected to the coil 403, and a drill bit 505 magnetically connected to the electromagnet 404, and the head changing assembly also includes a side frame 301 arranged at one side of the top end of the connecting frame 3, a first motor 5 is arranged on the top of the side frame 301, and the output shaft of the first motor 5 is fixedly connected to the connecting rod 501, and the bottom end of the connecting rod 501 is provided with an extension rod.

[0046] By arranging a coil 403 on the output shaft of the drilling machine 402, and arranging an electromagnet 404 on the coil 403, when the drill bit 505 needs to be replaced, the coil 403 can be powered off so that the electromagnet 404 no longer has magnetic force, thereby causing the drill bit 505 adsorbed on the electromagnet 404 by magnetic force to fall off, so that the drill bit 505 can be quickly replaced. In addition, by arranging a first motor 5, the output shaft of the first motor 5 is fixedly connected to the connecting rod 501, an extension rod 502 is arranged on the connecting rod 501, a second motor 503 is arranged on the extension rod 502, the second motor 503 is connected to a placement ring 504, and a plurality of drill bits 505 are plugged into the placement ring 504, so that when the drill bit 505 needs to be replaced, the first motor 5 can be started to drive the connecting rod 501 to rotate. After adjusting the direction of the extension rod 502, turn off the first motor 5, start the second motor 503 to rotate the placement ring 504 until the idle socket overlaps with the electromagnet 404, turn off the second motor 503, cut off the power to the coil 403, so that the drill bit 505 falls into the socket, and then start the second motor 503 again to rotate the placement ring 504 according to the required aperture until the slot 506 provided on the drill bit 505 of corresponding specifications overlaps with the electromagnet 404, start the telescopic rod 401 to lower the telescopic rod 401 into the slot 506, power the coil 403 so that the electromagnet 404 absorbs the drill bit 505, start the telescopic rod 401 to drive the drill bit 505 to rise, turn off the second motor 503, start the first motor 5 to reverse the position of the extension rod 502 again, and the replacement operation of the drill bit 505 can be quickly completed.

[0047] The present invention provides another technical solution:

[0048] See also Figure 2 , Figure 3 , Figure 5 and Figure 6 , also includes a positioning component, the positioning component includes a positioning box 6 rotatably connected to the platform body 1, the bottom surface of the positioning box 6 is fixedly connected to the output shaft of the fourth motor 8, the fourth motor 8 is fixedly connected to the platform body 1, a positioning frame 601 is installed in the positioning box 6, the bottom surface of the positioning frame 601 is fixedly connected to the third motor 7, the positioning frame 601 is slidably connected to a cross block 602, the output shaft of the third motor 7 is fixedly connected to a screw rod 701, the screw rod 701 passes through the positioning frame 601 and is threadedly connected to the cross block 602, a sliding sleeve 603 is slidably connected to the cross block 602, a U-shaped block 606 is slidably connected to the positioning frame 601, and a driving rod 604 and a driven rod 605 are rotatably connected on both sides of the sliding sleeve 603, respectively. The other end of the driving rod 604 is rotatably connected to the positioning frame 601, and the other end of the driven rod 605 is rotatably connected to the U-shaped block 606, and the top surface of the U-shaped block 606 is fixedly connected to a positioning rod 607.

[0049] By adopting the above design, the flange can be placed on the top surface of the positioning box 6, and then the third motor 7 is started to drive the screw 701 to rotate, driving the cross block 602 to rise, and one end of the driving rod 604 is rotatably connected to the positioning frame 601. The positioning frame 601 does not move and the cross block 602 rises. The position of the sliding sleeve 603 will be pushed toward the center of the positioning box 6 as the cross block 602 rises. The distance between the driven rod 605 remains unchanged, and the two ends are rotatably connected to the sliding sleeve 603 and the U-shaped block 606. The movement of the sliding sleeve 603 will push the U-shaped block 606 to slide in the positioning frame 601, thereby controlling the positioning rod 607 on the top of the U-shaped block 606 to move closer to or away from the center of the top surface of the positioning box 6, thereby adaptively clamping the flange on the top surface of the positioning box 6.

[0050] As another preferred embodiment of the present invention, according to the position of the positioning rod 607, a negative pressure hole is opened on the side of the positioning rod 607 that can be in contact with the flange. Preferably, the negative pressure holes are arranged on the positioning rod 607 from top to bottom, and when the positioning rod 607 slides relatively until it is in contact with the flange to fix the flange, the negative pressure holes are completely closed by the flange. A pressure regulating cavity is opened in the middle of the positioning rod 607, the pressure regulating cavity is connected with the negative pressure hole, and a pressure regulating port is opened at the top of the positioning rod 607, a rotating shaft is rotatably installed in the pressure regulating port, the rotating shaft is located in the pressure regulating cavity and is threadedly equipped with a pressure regulating slider, and the bottom of the pressure regulating slider has an elastic The sealing gasket, when the pressure-regulating slider slides in the pressure-regulating chamber, the air pressure in the pressure-regulating chamber will be adjusted. Preferably, the rotating shaft is rotatably connected to the pressure-regulating chamber and the pressure-regulating port by means of a sealing bearing installed at the pressure-regulating port. A knob can be provided on the top of the rotating shaft. Turning the knob drives the rotating shaft to rotate clockwise, so that the pressure-regulating slider slides upward. At this time, the pressure-regulating chamber is in a negative pressure state, which will give an adsorption force to the flange that closes the negative pressure hole, which is beneficial to improving the fixing effect. It should be noted that before the rotating shaft rotates and when it rotates to the pressure-regulating chamber to be in the above-mentioned negative pressure state, the height of the pressure-regulating slider is higher than any negative pressure hole (this embodiment is not shown in the accompanying drawings).

[0051] As another preferred embodiment of the above embodiment, negative pressure holes can be set on both sides of the positioning rod 607. When the positioning rod 607 positions the flange from the outside, the outer negative pressure hole of the positioning rod 607 close to the flange is closed by the positioning rod 607, and when the positioning rod 607 positions the flange from the inside, the inner negative pressure hole of the positioning rod 607 close to the flange is closed by the flange (this embodiment is not shown in the accompanying drawings).

[0052] In this embodiment, the pressure regulating chamber is composed of a cylindrical chamber of an upper and lower part, the inner diameter of the cylindrical chamber of the upper part is larger than the inner diameter of the cylindrical chamber of the lower part, and the pressure regulating slider includes a cylindrical structure located in the upper section and an annular structure in the lower section, the outer diameter of the annular structure is smaller than the outer diameter of the cylindrical structure, and a vertical long strip opening is arranged on the circumferential surface of the annular structure in the lower section, when the long strip opening corresponds to the negative pressure hole on one side, its width can just allow all the negative pressure holes on this side to be exposed, and the long strip opening is longer than the negative pressure holes at the top and bottom, the rotating shaft is fixedly connected to the pressure regulating slider, a knob is arranged on the top of the rotating shaft, the upper half of the pressure regulating chamber is connected to the cylindrical structure of the upper section of the pressure regulating slider through a sealing thread, the bottom end of the sealing thread is located above the highest negative pressure hole, the part of the pressure regulating chamber below the sealing thread is a smooth inner wall, and the outer arc surface of the annular structure of the lower section of the pressure regulating slider is in a sealed fit with the lower half of the pressure regulating chamber, and can rotate with the rotating shaft.

[0053] When it is necessary to position the flange from the outside, first control the positioning rod 607 to fit with the flange. At this time, the negative pressure hole that fits with the flange is closed by the flange. Then, turn the knob clockwise to drive the rotating shaft and the pressure regulating slider to rotate. At this time, the pressure regulating slider is gradually screwed out of the pressure regulating chamber by using the sealing thread. When the long strip opening on the annular structure of the lower section just misses the negative pressure hole on the other side and the negative pressure hole on that side is also closed, the pressure regulating chamber is in a sealed state. Continue to rotate by a predetermined angle until the negative pressure hole on that side is aligned with the long strip opening again. The entire negative pressure chamber is in a sealed state, and in this process, the sealing thread is used to make the pressure regulating slider slide out of the pressure regulating chamber. Therefore, the inside of the pressure regulating chamber is in a negative pressure state, so that the negative pressure hole that is in contact with the flange can be in a negative pressure state, thereby improving the stability of the flange fixation. It should be noted that before turning the knob and when turning the knob to put the negative pressure hole in a negative pressure state, the cylindrical structure of the upper section of the pressure regulating slider maintains a threaded fit with the cylindrical cavity in the upper half, and the bottom end of the adjusting slider is still below the bottommost negative pressure hole.

[0054] Working principle:

[0055] When in use, first open the cabinet door of the table body 1, and then place the flange to be processed on the top surface of the positioning box 6, and control the third motor 7 through the control panel 101 to drive the screw 701 to rotate, so that the positioning rod 607 moves closer to the center of the top surface of the positioning box 6, and then clamps and fixes the flange, thereby completing the placement and fixation of the flange.

[0056] When adjusting the drilling position, by holding the handle 207, the driving disk 201 is driven to rotate, and then the driven disk 202 is driven to rotate, thereby changing the staggered positions of multiple guide grooves 203 and limit grooves 204, so that the positions of the drills 402 set on the multiple connecting frames 3 are changed, thereby realizing the adjustment of the drilling position of the flange.

[0057] When adjusting the aperture, the coil 403 is powered off through the control panel 101, the first motor 5 is controlled to rotate one hundred and eighty degrees, the drill bit 505 in the placement ring 504 is moved to under the electromagnet 404, the second motor 503 is started to drive the drill bit 505 to rotate, so that the position of the required slot 506 of the drill bit 505 overlaps with the electromagnet 404, the electromagnet 404 is controlled to descend into the slot 506, and the coil 403 is energized so that the electromagnet 404 absorbs the drill bit 505, so that the adjustment of the drilling aperture can be completed quickly and safely by replacing the drill bit 505.

[0058] When drilling, the telescopic rod 401 is extended through the lifting cylinder 4, driving the drill 402 to descend to contact the flange, and the drill 402 is started to drive the electromagnet 404 to rotate, thereby rotating the drill bit 505. The drilling operation of the flange on the top surface of the positioning box 6 is realized through the rotation of the drill bit 505. The fourth motor 8 is started to drive the positioning box 6 to rotate, and the position of the flange can be adjusted. The processing of the flange is completed through multiple adjustments and drilling.
