Description

Technical Field

[0001] The present invention relates to the technical field of drilling devices, and particularly relates to a drilling device for producing feed nozzles. Background Art

[0002] In the petrochemical field, the feed atomizing nozzle is an indispensable device in key processes such as catalytic cracking. Through its high-speed spraying and fine atomization functions, it evenly disperses the feedstock oil into the reactor to ensure the gas-liquid contact efficiency and reaction conversion rate. When assembling the feed atomizing nozzle, various components such as the nozzle body and the atomization core need to be combined according to strict process requirements to ensure the sealing performance and concentricity between components, so as to ensure the ideal atomization effect during the operation of the nozzle. Among them, the connection of the flange is a crucial link. The flange not only needs to have sufficient strength to withstand the high-pressure environment but also needs to ensure the sealing and connection stability with the nozzle through precise drilling. Therefore, a drilling device is required during the production of the feed nozzle, and the drilling device must have high-precision positioning and processing capabilities to ensure that the hole positions on the flange can accurately match the connection part of the nozzle, thereby ensuring the reliability of the entire nozzle system.

[0003] The existing drilling devices in the prior art, such as a flange positioning drilling device disclosed in the Chinese patent application document with the publication number CN114247916A, adjust the distance between the connecting plates through a double-finger cylinder, thereby realizing the clamping and fastening of the triangular clamping plate and the flange chassis. The flange is quickly positioned and clamped through the positioning shaft on the mounting plate. The setting of the brake motor can perform timely lifting and height adjustment according to different sizes of flanges, which is applicable to flange chassis with different thicknesses. And the chassis of the flange is further stabilized by using a pressing plate. The positioning holes provided on the cover plate are arranged in a circumferential array and are equally divided into 20 positioning holes, which can be applicable to multi-hole flanges such as four-hole and five-hole flanges. Through the positioning disk, rapid positioning can be achieved without coordinate positioning, and the turntable can drive the drilling machine to perform circular motion to realize drilling operations at various angles.

[0004] However, during the operation of the above-mentioned flange positioning drilling device in the prior art, the operator needs to manually place the flange on the mounting plate and make the through hole of the flange cooperate with the positioning shaft, and remove the flange from the positioning shaft of the mounting plate after drilling. Manual operation not only takes a lot of time but also easily causes position deviation due to improper operation and requires repeated adjustment. Especially in large-scale production, it will significantly reduce the production efficiency. Summary of the Invention

[0005] The present invention provides a drilling device for producing feed nozzles, aiming to solve the problem that the manual placement and removal of the flange in the related flange positioning drilling device are time-consuming and laborious and will significantly reduce the production efficiency.

[0006] A drilling device for manufacturing a feed nozzle provided by the present invention adopts the following technical solution:

[0007] A drilling device for manufacturing a feed nozzle includes a drilling assembly and a lifting assembly spaced apart from below the drilling assembly. The lifting assembly includes two swing plates distributed left and right and relatively rotatable, and a swing driver for driving the two swing plates to swing. When the two swing plates swing to a horizontal state, a lifting station for lifting a flange to drill the flange is formed. When the two swing plates swing downward to an inclined state, a feeding station for conveying the flange is formed;

[0008] One of the swing plates is a loading plate, a loading table is arranged on the side of the loading plate away from the swing axis, the other swing plate is a unloading plate, a material pushing portion extending towards the loading plate is arranged on the side of the unloading plate close to the swing axis, a unloading table is arranged on the side of the unloading plate away from the swing axis, fixing jigs for clamping the flange left and right are respectively arranged on the loading table and the unloading table, and jig drivers corresponding to the fixing jigs for driving the fixing jigs to move left and right are arranged;

[0009] The side of the loading table facing the swing axis has a V-shaped inclined loading surface for guiding the flange to slide towards the center of the fixing jig when the loading plate is at the feeding station; the side of the unloading table facing the swing axis has an inclined unloading surface for guiding the flange to slide and unload along the unloading surface when the unloading plate is at the feeding station.

[0010] Adopting the above technical solution, the two swing plates are driven to swing by the swing driver, so that the two swing plates are switched between the horizontal lifting station and the inclined feeding station, and the automatic sliding-in of the flange to be processed and the automatic sliding-out of the processed flange are realized by using the loading table with a V-shaped inclined loading surface arranged on the loading plate and the unloading table with an inclined unloading surface arranged on the unloading plate. It can perform full-automatic loading and unloading, reduce manual intervention and operation time, improve production efficiency, and is suitable for large-scale production; during the automatic sliding-in process, the V-shaped inclined loading surface can combine with the gravity to guide the flange to be processed to automatically slide towards the center of the fixing jig, so that the flange to be processed is automatically centered and positioned, which is convenient for the fixing jig to automatically clamp the flange, avoiding the position deviation and repeated adjustment that may be caused by manual operation, and improving the processing accuracy.

[0011] Furthermore, the drilling device for manufacturing a feed nozzle further includes a machine shell. The drilling assembly and the lifting assembly are respectively installed in the machine shell. An operation opening facing the drilling assembly is opened on the machine shell, and a sealing window is installed at the operation opening. The sealing window is made of a transparent material.

[0012] With the above technical solution, the casing can prevent the debris generated during the drilling process from spreading to the surrounding environment, keep the working environment clean, protect the operators from harm, and prevent dust, impurities, etc. in the external environment from entering the processing area, avoiding affecting the processing process and quality; the operation opening enables the operator to directly access the drilling assembly, facilitating drilling operations, replacing drill bits, adjusting the drilling position, etc.; the sealed window enables the operator to clearly observe the drilling process, ensuring the accuracy and safety of the operation.

[0013] Further, a stock preparation table is arranged outside the casing and is distributed below the sealed window. The casing is provided with a feeding port located between the sealed window and the stock preparation table. The upper surface of the stock preparation table has a feeding groove for docking with the feeding surface when the feeding table is at the feeding station and a discharging groove for docking with the discharging surface when the discharging table is at the feeding station.

[0014] With the above technical solution, the stock preparation table serves as a flange temporary storage and transfer platform, realizing the orderly stacking and transfer of flanges before and after processing; the feeding port serves as a channel for flanges to enter and exit the processing area, connecting the internal lifting assembly and the external stock preparation table; the feeding groove and the discharging groove form a directional track for the flange to slide in and out. The feeding groove is used to convey the flanges to be processed to the lifting assembly, and the discharging groove is used to receive the processed flanges. The separate groove design stores the workpieces to be processed and the finished products independently, avoiding material mixing, supporting continuous flow operation, being conducive to reducing the operation time, and improving production efficiency.

[0015] Further, perforations distributed front and back are respectively formed in the side edges of the two swing plates close to each other. The drilling device for production with the feeding nozzle further includes a pin shaft extending front and back and passing through the perforations.

[0016] Further, the swing drive includes a motor, a screw rod extending vertically and arranged at the output end of the motor, a lifting block mounted on the screw rod, and a connecting rod connecting between the lifting block and the lower surfaces of the swing plates. One end of the connecting rod close to the lifting block is rotatably connected to the lifting block, and the other end far from the lifting block is rotatably connected to the lower surface of the swing plate.

[0017] Further, chip discharge grooves extending left and right are respectively formed on the feeding table and the discharging table. One end of the chip discharge groove close to the swing plate has a chip inlet, the upper end surface of the chip inlet is higher than the upper surface of the swing plate, and the other end of the chip discharge groove far from the swing plate has a chip outlet.

[0018] With the above technical solution, after being transferred to the feeding station, the chip removal groove is tilted accordingly with the swing plate. The chip inlet is at the upper end of the chip removal groove, so that the fine chips generated during the drilling process can slide along the upper surface of the swing plate into the chip inlet under the action of gravity and enter the chip removal groove. The chip outlet is at the lower end of the chip removal groove, so that the chips in the chip removal groove can be discharged from the chip outlet under the action of gravity, realizing the automatic cleaning and discharging of the chips after each processing.

[0019] Further, each of the swing plates is provided with a receiving groove communicating with the chip removal groove, and a lifting plate is movably assembled up and down in the receiving groove. A lifting driving member for driving the lifting plate to lift and lower is installed on the swing plate. The lifting driving member can drive the lifting plate to descend when the swing plate is at the feeding station, so that the lifting plate enlarges the chip inlet.

[0020] With the above technical solution, when large chips are likely to be generated during the drilling process, it can be set that the lifting driving member drives the lifting plate to descend after each drilling is completed, the processed flange is unloaded, and the swing plate is at the feeding station, so that the lifting plate enlarges the chip inlet, facilitating the large chips to enter the chip removal groove through the chip inlet, thereby ensuring the chip cleaning effect.

[0021] Further, each of the fixed clamps includes a first clamp and a second clamp located below the first clamp. The side surface of the first clamp facing the flange forms a clamping surface for abutting against the outer peripheral side of the flange. The second clamp has an extending table extending towards the flange. The upper surface of the extending table is used to support the flange. The extending table has a guiding surface that slopes downward from the extending table towards the flange, and the guiding surface is used to guide the flange to move towards the upper surface of the extending table. Each of the clamp drivers includes a first linear driver corresponding to the first clamp for driving the first clamp to move left and right, and a second linear driver corresponding to the second clamp for driving the second clamp to move left and right.

[0022] Further, the clamping surface is arc-shaped or V-shaped.

[0023] Further, the material pushing part is located at the middle position in the front-back direction of the blanking plate, and a slot adapted to the material pushing part is opened on the loading plate.

[0024] The beneficial effects of a drilling device for the production of a feed nozzle provided by the present invention are as follows: By driving two swing plates to swing through a swing driver, the two swing plates are switched between a horizontal lifting station and an inclined feeding station, and by using a feeding table with a V-shaped inclined feeding surface provided on the feeding plate and a discharging table with an inclined discharging surface provided on the discharging plate, the automatic sliding-in of the flange to be processed and the automatic sliding-out of the processed flange are realized, enabling full-automatic loading and unloading, reducing manual intervention and operation time, improving production efficiency, and being suitable for large-scale production; during the automatic sliding-in process, the V-shaped inclined feeding surface can combine with the gravity to guide the flange to be processed to automatically slide towards the center of the fixed fixture, enabling the automatic centering and positioning of the flange to be processed, facilitating the automatic clamping of the flange by the fixed fixture, avoiding the position deviation and repeated adjustment that may be caused by manual operation, and improving the processing accuracy.

[0034] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0035] As Figures 1 to 7 shown, and with reference to Figure 1 the orientation shown in

[0036] As Figure 1 and Figure 2As shown, the housing 10 is generally in the shape of a cuboid. The drilling assembly 20, the lifting assembly 30, and the clamping assembly 40 are respectively installed inside the housing 10. The housing 10 can prevent the debris generated during the drilling process from spreading to the surrounding environment, keep the working environment clean, protect the operator from harm, and prevent dust, impurities, etc. in the external environment from entering the processing area, avoiding affecting the processing process and quality. An operation opening facing the drilling assembly 20 is provided on the housing 10, and a sealing window 110 is installed at the operation opening. The setting of the operation opening enables the operator to directly access the drilling assembly 20, facilitating drilling operations, replacing drill bits, adjusting drilling positions, etc. The sealing window 110 is a casement window that is convenient for opening and closing, and is made of transparent materials such as acrylic or tempered glass, enabling the operator to clearly observe the drilling process and ensuring the accuracy and safety of the operation.

[0037] A stock preparation table 130 is provided outside the housing 10 and is distributed below the sealing window 110. The stock preparation table 130 serves as a flange temporary storage and transfer platform, realizing the orderly stacking and transfer of flanges before and after processing. The housing 10 is provided with a feeding port 120 located between the sealing window 110 and the stock preparation table 130, serving as a channel for the flange to enter and exit the processing area, connecting the internal lifting assembly 30 and the external stock preparation table 130. The upper surface of the stock preparation table 130 has a loading groove 131 and an unloading groove 132 distributed left and right, forming a directional track for the flange to slide in and out. The loading groove 131 is used to convey the flange to be processed to the lifting assembly 30, and the unloading groove 132 is used to receive the processed flange. The divided groove design enables the workpieces to be processed and the finished products to be stored independently, avoiding material mixing, supporting continuous flow operation, being conducive to reducing operation time, and improving production efficiency.

[0038] As Figure 1 and Figure 2 shown, the drilling assembly 20 includes a rotating table rotatably installed inside the housing 10, a drill bit installed on the rotating table, a feed driver installed on the rotating table for controlling the feed speed and feed direction of the drill bit, and a rotary driver for driving the rotation of the rotating table to adjust the position of the drill bit.

[0039] As Figures 2 to 7 shown, the lifting assembly 30 includes a swing plate 310, a swing driver 320, a loading table 330, an unloading table 340, a pin shaft 350, a lifting plate 380, and a lifting driving member 390.

[0040] The pin shaft 350 extends forward and backward and is fixed on the front and rear inner walls of the housing 10. The central position of the pin shaft 350 is vertically aligned with the central position of the drilling assembly 20. The two swing plates 310 are symmetrically distributed on the left and right sides of the pin shaft 350. The side edges of the two swing plates 310 close to each other are respectively provided with perforations distributed front and back. The pin shaft 350 passes through the perforations of the two swing plates 310, enabling the two swing plates 310 to rotate relative to each other around the pin shaft 350.

[0041] The swing drive 320 is used to drive the two swing plates 310 to swing. The swing drive 320 includes a motor 321 mounted at the bottom of the housing 10, a screw 322 arranged at the output end of the motor 321 and extending vertically, a lifting block 323 mounted on the screw 322, and a connecting rod 324 connected between the lifting block 323 and the lower surface of each swing plate 310. One end of the connecting rod 324 close to the lifting block 323 is rotatably connected to the lifting block 323, and the end far from the lifting block 323 is rotatably connected to the lower surface of the swing plate 310. In the embodiment, two connecting rods 324 connected to the lower surface of each swing plate 310 are respectively arranged on the left and right sides of the lifting block 323 to limit the circumferential rotation of the lifting block 323. When the motor 321 drives the screw 322 to rotate, the rotation of the screw 322 can drive the lifting block 323 to move up and down along the screw 322. The up and down movement of the lifting block 323 is transmitted to the swing plate 310 through the connecting rod 324, so that the two swing plates 310 swing up or down synchronously around the pin shaft 350.

[0042] When the two swing plates 310 swing to the horizontal state, they enter the lifting station. The upper surfaces of the two swing plates 310 are horizontally aligned to form a stable support surface for drilling the flange. When the two swing plates 310 swing down to the inclined state, they enter the feeding station. The two swing plates 310 form an inverted V-shaped chute to realize the automatic feeding and discharging of the flange by gravity.

[0043] The swing plate 310 on the left side is the loading plate 311. A slot is provided on one side of the loading plate 311 close to the pin shaft 350, and the slot is located at the middle position in the front and rear directions of the loading plate 311. A loading table 330 is arranged on the side of the loading plate 311 far from the pin shaft 350, and the side of the loading table 330 facing the pin shaft 350 has a V-shaped inclined loading surface 331. One end of the loading surface 331 close to the stock preparation table 130 can be docked with the loading chute 131 when the loading plate 311 is in the feeding station. Correspondingly, the loading chute 131 should have an inclined angle matching the V-shaped surface of the loading table 330. The middle position of the loading surface 331 in the front and rear directions, that is, the lowest point of the loading surface 331 when the loading plate 311 is in the feeding station, is relatively centered with the center position of the pin shaft 350 left and right, and is used to guide the flange to slide to the middle position in the front and rear directions of the loading surface 331 during the loading process to realize the automatic loading and automatic centering of the flange.

[0044] The swing plate 310 on the right side is the blanking plate 312. One side of the blanking plate 312 close to the pin shaft 350 has a material pushing portion 313 extending towards the feeding plate 311 and adapted to the slot. The material pushing portion 313 is used to push the processed flange to slide along the upper surface of the blanking plate 312 when the blanking plate 312 swings downward, so as to prevent the flange from getting stuck in the gap of the swing plate 310. A blanking table 340 is arranged on the side of the blanking plate 312 away from the pin shaft 350. The side of the blanking table 340 facing the pin shaft 350 has an inclined blanking surface 341. One end of the blanking surface 341 close to the stock preparation table 130 can be docked with the blanking groove 132 when the blanking plate 312 is in the feeding station. Accordingly, the blanking groove 132 should have an inclined angle consistent with the inclined surface of the blanking table 340. The blanking surface 341 is used to guide the flange to slide and blank along the blanking surface 341 when the blanking plate 312 is in the feeding station, so as to realize the automatic blanking of the flange.

[0045] Chip removal grooves 360 extending left and right are respectively formed on the feeding table 330 and the blanking table 340. One end of the chip removal groove 360 close to the swing plate 310 has a chip inlet, and the upper end surface of the chip inlet is higher than the upper surface of the swing plate 310, which is used to allow fine chips to enter the chip removal groove 360. One end of the chip removal groove 360 away from the swing plate 310 has a chip outlet, and the chip outlet communicates with the inside of the machine housing 10. After switching to the feeding station, the chip removal groove 360 is inclined correspondingly with the swing plate 310, and the chip inlet is at the upper end of the chip removal groove 360, so that the fine chips generated during the drilling process can slide along the upper surface of the swing plate 310 under the action of gravity and enter the chip removal groove 360 through the chip inlet. The chip outlet is at the lower end of the chip removal groove 360, so that the chips in the chip removal groove 360 can be discharged from the chip outlet under the action of gravity and fall to the bottom inside the machine housing 10, realizing the automatic cleaning and discharging of the chips after each processing. In other embodiments, a collection groove for receiving and collecting chips can also be arranged inside the machine housing 10 below the chip outlet to facilitate the centralized cleaning of the chips.

[0046] Each swing plate 310 is provided with a receiving groove 370 communicating with the chip discharge groove 360, and a lifting plate 380 is movably assembled up and down in the receiving groove 370. A lifting driving member 390 for driving the lifting of the lifting plate 380 is installed on the swing plate 310. The lifting driving member 390 in the embodiment is a hydraulic cylinder. In other embodiments, the lifting driving member 390 may also be a pneumatic cylinder or an electric push rod. Under normal working conditions, the lifting driving member 390 drives the lifting plate 380 to rise until the upper surface of the lifting plate 380 is flush with the upper surface of the swing plate 310 to avoid affecting the normal operation of the swing plate 310. When large and coarse chips are easily generated during drilling, such as when the flange material has good toughness and is prone to deformation during cutting, and the generated chips are long and continuous, it can be set that when each drilling is completed, the processed flange is unloaded, and when the swing plate 310 is in the feeding station, the lifting driving member 390 drives the lifting plate 380 to descend, so that the lifting plate 380 expands the chip inlet, facilitating the entry of large and coarse chips into the chip discharge groove 360, thereby ensuring the chip cleaning effect.

[0047] As Figures 2 to 4 shown, the clamping assembly 40 includes a fixed fixture and a fixture driver. Fixed fixtures for clamping the flange are respectively arranged on the loading table 330 and the unloading table 340 in a left-right opposite manner, and fixture drivers for driving the fixed fixtures to move left and right corresponding to each fixed fixture are provided. The fixed fixtures are left-right opposite to the central position of the pin shaft 350. Fixture grooves for accommodating the fixtures are respectively formed on the loading table 330 and the unloading table 340, so that the fixtures can be retracted into the fixture grooves to avoid affecting the loading and unloading process.

[0048] Each fixed fixture includes a first fixture 411 and a second fixture 421 located below the first fixture 411. The side surface of the first fixture 411 facing the flange forms a clamping surface for abutting against the outer peripheral side of the flange, and the clamping surface is arc-shaped or V-shaped. The second fixture 421 has an extending platform extending towards the flange. The upper surface of the extending platform is used for supporting the flange, the lower surface of the extending platform is attached to the upper surface of the swing plate 310, and the extending platform has a guiding surface inclined downward from the extending platform towards the flange, and the guiding surface is used for guiding the flange to move towards the upper surface of the extending platform. Each fixture driver includes a first linear driver 410 corresponding to the first fixture 411 for driving the first fixture 411 to move left and right, and a second linear driver 420 corresponding to the second fixture 421 for driving the second fixture 421 to move left and right. The first linear driver 410 and the second linear driver 420 in the embodiment are both hydraulic cylinders. In other embodiments, the first linear driver 410 and the second linear driver 420 may also be pneumatic cylinders or electric push rods.

[0049] The fixed fixture is divided into two fixtures in layers. The first fixture 411 is used to fit the outer contour of the flange, providing radial clamping force to ensure the horizontal fixation of the flange and avoid lateral deviation during drilling. The second fixture 421 is used to move left and right to make the extension table enter below the flange, lift the flange to a preset height, and form a gap between the lower surface of the flange and the swing plate 310, ensuring that the drill bit can completely penetrate the flange without interfering with the lower swing plate 310 during drilling.

[0050] The working process of the embodiment of the drilling device for producing the feed nozzle of the present invention includes the following steps:

[0051] In the first step, loading: The motor 321 drives the screw 322 to rotate, driving the lifting block 323 to move downward. Through the connecting rod 324, the left and right swing plates 310 swing downward to an inclined state and enter the feeding station. The flange to be processed slides from the feeding groove 131 of the stock table 130 onto the feeding surface 331 of the loading table 330, and slides under the guidance of the feeding surface 331 to the middle position in the front-back direction of the feeding surface 331, that is, at the fixed fixture.

[0052] In the second step, clamping: The motor 321 rotates in reverse, and the two swing plates 310 swing to a horizontal state and enter the lifting station, forming a stable support surface. The first linear actuator 410 and the second linear actuator 420 respectively drive the first fixture 411 and the second fixture 421 to extend. The first fixture 411 stops moving after contacting the flange, and the second fixture 421 continues to extend and lift the flange to a preset height, forming a gap between the lower surface of the flange and the swing plate 310.

[0053] In the third step, drilling: The rotary actuator of the drilling assembly 20 adjusts the position of the drill bit, and the feed actuator controls the drill bit to press down to penetrate the flange for drilling.

[0054] In the fourth step, unloading: The first fixture 411 and the second fixture 421 retract to release the flange. The motor 321 drives the swing plate 310 to tilt again. The material pushing part 313 of the unloading plate 312 pushes the processed flange to slide along the upper surface of the unloading plate 312 to the unloading table 340, and slides into the unloading groove 132 along the unloading surface 341 to complete automatic unloading.

[0055] Thus, in the embodiment of the drilling device for manufacturing the feed nozzle of the present invention, the swing driver 320 drives the two swing plates 310 to swing, so that the two swing plates 310 are switched between the horizontal lifting station and the inclined feeding station. By using the feeding table 330 provided on the feeding plate 311 with a V-shaped inclined feeding surface 331 and the discharging table 340 provided on the discharging plate 312 with an inclined discharging surface 341, the automatic sliding-in of the flange to be processed and the automatic sliding-out of the processed flange are realized. It can perform full-automatic loading and unloading, reduce manual intervention and operation time, improve production efficiency, and is suitable for large-scale production. During the automatic sliding-in process, the V-shaped inclined feeding surface 331 can combine with the gravity to guide the flange to be processed to automatically slide towards the center of the fixed fixture, so that the flange to be processed is automatically centered and positioned, which is convenient for the fixed fixture to automatically clamp the flange, avoiding the position deviation and repeated adjustment that may be caused by manual operation and improving the processing accuracy.

[0056] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
