Description

Technical Field

[0001] The present invention relates to the technical field of packing box production and processing, and particularly relates to a drilling processing device for packing box accessories. Background Art

[0002] In fields such as petrochemical industry and pipeline engineering, the drilling processing of the flange of the packing box is a key assembly link. A high-precision flange can greatly improve the sealing performance and working stability of the packing box.

[0003] Existing drilling equipment for packing box flanges mostly uses single-size fixtures. For flanges of different diameters, the fixtures need to be frequently replaced (such as the DN50-DN300 series), resulting in low efficiency and difficult to guarantee the positioning accuracy. The traditional processing method generally drills it through a machine tool. This method requires manual positioning in advance, and drills each positioning point in turn until the drilling operation is completed. During the processing, the position spacing of each drilling is prone to errors, and it is difficult to ensure the consistency of the drilling positions. After the drilling position deviates, not only the overall installation stability of the packing box is poor, but also the sealing effect cannot be guaranteed, accelerating the damage of the packing box. Therefore, it is necessary to propose a drilling processing device for packing box accessories to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a drilling processing device for packing box accessories, which has the effects of high drilling accuracy and strong versatility.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: A drilling processing device for packing box accessories includes a base and a fixed ring fixed to the upper end of the base. Inside the cavity of the fixed ring, there is a positioning mechanism and a rotation adjustment part for fixing the packing box accessories. Above the fixed ring, there is also an adjustable drilling assembly. The positioning mechanism includes a first motor arranged at the bottom of the inner cavity of the base. The output end of the first motor is equipped with a one-way lead screw. There is a threaded sleeve outside the one-way lead screw. The top is rotatably connected to a fixed disk. Three limiting rods are installed on the outer circumference of the fixed disk. A sliding block is movably installed on the limiting rods. A support rod connecting the threaded sleeve is rotatably arranged at the bottom of the sliding block. A positioning seat is installed at the top. Inside the positioning seat, there are a support plate and a pressing part for fixing the end of the packing box accessories.

[0006] By adopting the above technical solution, the gland flange is placed above the fixed plate. The first motor drives the unidirectional lead screw to rotate, causing the threaded sleeve to move up and down. The sliding block is pushed by the support rod to slide back and forth on the limiting rod, thereby driving the three positioning seats to gather or disperse synchronously. The outer end face of the gland is clamped by the positioning seats and the support plates, and the upper end of the gland flange is pressed by the pressing member, so that the gland flange is stably locked. When drilling, the problem of deviation will not occur, and the drilling operation for gland flanges of different sizes can be satisfied.

[0007] The further setting of the present invention is that: the pressing member includes a screw rod arranged at the upper end of the positioning seat, and a pressing plate is fixedly installed at the bottom of the screw rod.

[0008] By adopting the above technical solution, rotate the screw rod to make the pressing plate move downwards to abut against the upper end face of the gland flange, thereby fixing it.

[0009] The further setting of the present invention is that: a movable frame is arranged on the fixed plate, a fitting placing table is fixedly installed at the upper end of the movable frame, and a plurality of springs connecting and fixing the upper end of the fixed plate are installed at the bottom of the fitting placing table.

[0010] By adopting the above technical solution, when pressing down the gland flange, the fitting placing table is also pushed down, squeezing the springs. Through the resilience of the springs, the bottom of the gland flange is further abutted tightly.

[0011] The further setting of the present invention is that: the rotation adjustment member includes a second motor installed on the outer wall of the base, a driving gear is installed at the output end of the second motor, a rotating ring is arranged at the upper end of the fixed ring, the inner wall of the rotating ring is fixedly connected to the ends of the three limiting rods, a toothed disc engaging with the driving gear is installed on the outer wall, a bracket is installed at the bottom of the base, and a rotating table fixedly connected to the first motor is rotatably arranged at the center of the bracket.

[0012] By adopting the above technical solution, the second motor rotates the driving gear to push the toothed disc to rotate, causing the rotating ring to rotate. Under the connection of the three limiting rods, the fixed plate rotates and drives the gland flange to rotate, thereby adjusting the drilling position of the gland flange. Through the setting of the bracket and the rotating table, the first motor can work stably.

[0013] The present invention is further configured as follows: the adjustable drilling assembly includes three fixing plates circumferentially mounted on the outer wall of the fixing ring, a fixing platform is mounted on the top between the three fixing plates, two first electric push rods are mounted on the fixing platform, a lifting frame is mounted between the output ends of the two first electric push rods, a connecting frame is mounted on the bottom of the lifting frame, two left-right symmetrical drill rods and adjusting parts for adjusting the distance between the two drill rods are arranged at both ends of the connecting frame, and a driving part for controlling the synchronous rotation of the two drill rods is also arranged on the connecting frame.

[0014] By adopting the above technical solution, the spacing between the two drill rods is adjusted by the adjusting member to correspond to the position of the holes to be drilled, and then the two drill rods are controlled to rotate by the driving member. The drill rods are pushed down by the first electric push rod to drill holes in the packing box flange, and the packing box flange is rotated in conjunction with the rotating adjusting member, thereby achieving drilling of the entire circumference of the packing box flange, making the drilling spacing more precise.

[0015] The present invention is further configured as follows: the driving member includes a dual-axis motor installed on one side of the bottom of the connecting frame, a telescopic rotating rod is installed at the output end of the dual-axis motor, a worm is installed at the other end of the telescopic rotating rod, and a worm wheel adapted to the worm is installed at the upper end of the drill rod.

[0016] By adopting the above technical solution, the telescopic rotating rods on both sides are driven to rotate by the double-axis motor, which drives the worms at both ends to rotate, and drives the drill rod to rotate through the engagement with the worm wheel.

[0017] The present invention is further configured as follows: the telescopic rotating rod includes a sleeve installed on the output end of the dual-axis motor, a sliding rod connected to the worm gear is installed at the other end of the sleeve, four guide blocks are installed at one end of the sliding rod located in the sleeve, and openings for the guide blocks to slide back and forth are provided on the four sides of the outer wall of the sleeve.

[0018] By adopting the above technical solution, when the drill rods on both sides are adjusting the spacing, the slide bar slides in the sleeve, and the cooperation between the guide block and the opening prevents the slide bar from separating from the sleeve, so that the movement and rotation are smoother.

[0019] The present invention is further configured as follows: the adjusting member includes a third motor installed on the side wall of the connecting frame, the output end of the third motor is installed with a main bevel gear, a bidirectional screw is rotatably arranged in the connecting frame, and movable plates threadedly connected to the bidirectional screw are slidably arranged on the left and right side walls, the movable plate is rotatably connected to the drill rod, and the bidirectional screw is installed with a slave bevel gear engaged with the main support.

[0020] By adopting the above technical solution, the third motor drives the main bevel gear to rotate, so that the slave bevel gear rotates, driving the bidirectional screw to rotate, thereby pushing the moving plates on both sides away from or close to each other, and adjusting the distance between the drill rods on both sides.

[0021] A further setting of the present invention is that two sliding blocks are installed at one end of the moving plate located inside the connecting frame, and notch openings for the left and right sliding of the sliding blocks are provided on the upper and lower side walls of the connecting frame.

[0022] By adopting the above technical solution, when the moving plate slides, the sliding blocks at the end are always sliding within the notch openings, making the sliding of the moving plate smoother.

[0023] A further setting of the present invention is that the adjustable drilling assembly further includes a fixed frame installed on the outer wall of the fixed ring. A fourth motor is installed at the upper end of the fixed frame, an adjusting screw rod is installed at the output end of the fourth motor, a vertical rod and a moving frame that is threadedly connected to the adjusting screw rod and slidably connected to the vertical rod are installed inside the fixed frame. A second electric push rod is installed on the moving frame, and a lateral drilling member is installed at the output end of the second electric push rod.

[0024] By adopting the above technical solution, the drilling member consists of a drilling motor and a drill rod, which belongs to the well-known technology in the field. By pushing the drilling member to move towards the side of the stuffing box flange through the second electric push rod, the side of the stuffing box flange can be drilled. By driving the adjusting screw rod to rotate through the fourth motor, under the guidance of the vertical rod, the drilling member moves up and down, so as to drill holes at different heights on the side of the stuffing box flange.

[0025] The beneficial effects of the present invention are: 1. In the present invention, by placing the stuffing box flange on the upper side of the fixed disk, driving the one-way screw rod to rotate by the first motor, the threaded sleeve moves up and down, and the sliding block is pushed by the support rod to slide back and forth on the limiting rod, thereby driving the three positioning seats to gather or disperse synchronously, so that the outer end face of the stuffing box is clamped by the positioning seats and the support plates. Rotate the screw rod to lower the pressure plate so that it abuts against the upper end face of the stuffing box flange, thereby fixing it, so that the stuffing box flange is stably locked, and when drilling, it will not deviate, and it can meet the drilling operations for stuffing box flanges of different sizes.

[0026] 2. In the present invention, by driving the driving gear to rotate by the second motor, the toothed disk is pushed to rotate, so that the rotating ring rotates. Under the connection of the three limiting rods, while the fixed disk rotates, the stuffing box flange is driven to rotate, thereby adjusting the drilling position of the stuffing box flange, automatically completing the drilling of the entire circumference of the stuffing box flange, and the drilling spacing is more accurate.

[0027] 3. In the present invention, the telescopic rotating rods on both sides are driven by a biaxial motor to rotate, driving the worm gears at both ends to rotate, and the drill rod is pushed to rotate through meshing with the worm wheels for drilling. The main bevel gear is driven by a third motor to rotate, causing the driven bevel gear to rotate and driving the bidirectional lead screw to rotate, thereby pushing the moving plates on both sides away from or closer to each other, adjusting the distance between the drill rods on both sides, so as to meet the drilling requirements in different situations.

Detailed implementation mode

[0036] The technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] As Figure 1 , Figure 2 , Figure 3 shown, a drilling processing device for packing box fittings includes a base 1 and a fixing ring 2 fixed to the upper end of the base 1. Inside the cavity of the fixing ring 2, there is a positioning mechanism 3 for fixing the packing box fittings and a rotation adjustment part 4. Above the fixing ring 2, there is also an adjustable drilling assembly 5. The positioning mechanism 3 includes a first motor 31 arranged at the bottom of the inner cavity of the base 1. The output end of the first motor 31 is equipped with a unidirectional lead screw 32. The outside of the unidirectional lead screw 32 is provided with a threaded sleeve 33, and the top is rotatably connected to a fixing plate 34. The outer circumference of the fixing plate 34 is installed with three limiting rods 35. A sliding block 36 is movably installed on the limiting rods 35. The bottom of the sliding block 36 is rotatably provided with a support rod 37 connecting to the threaded sleeve 33, and the top is installed with a positioning seat 38. Inside the positioning seat 38, there are a support plate 314 and a pressing part for fixing the end of the packing box fitting. The pressing part includes a screw 39 arranged at the upper end of the positioning seat 38, and a pressing plate 310 is fixedly installed at the bottom of the screw 39.

[0038] Place the packing box flange above the fixed disk 34. Drive the unidirectional lead screw 32 to rotate by the first motor 31, so that the threaded sleeve 33 moves up and down. Push the sliding block 36 to slide back and forth on the limit rod 35 through the support rod 37, thereby driving the three positioning seats 38 to gather or disperse synchronously, so that the outer end face of the packing box is clamped by the positioning seats 38 and the support plate 314, and the upper end of the packing box flange is pressed by the pressing member, so that the packing box flange is stably locked, so that when drilling, there will be no offset problem, and it can meet the drilling operation of packing box flanges of different sizes. Rotate the screw 39 to make the pressing disk 310 move down and press against the upper end face of the packing box flange, thereby fixing it.

[0039] As Figure 4 shown, an activity frame 311 is arranged on the fixed disk 34. The upper end of the activity frame 311 is fixedly installed with a fitting placement table 312. A plurality of springs 313 connecting the upper end of the fixed disk 34 are installed at the bottom of the fitting placement table 312. When pressing down the packing box flange, the fitting placement table 312 is also pushed down, squeezing the springs 313. Through the rebound of the springs 313, the bottom of the packing box flange is further pressed tightly.

[0040] As Figure 2 、 Figure 7 shown, the rotation adjustment member 4 includes a second motor 41 installed on the outer wall of the base 1. The output end of the second motor 41 is installed with a driving gear 42. The upper end of the fixed ring 2 is provided with a rotating ring 43. The inner wall of the rotating ring 43 is fixedly connected to the ends of the three limit rods 35, and a toothed disk 44 engaged with the driving gear 42 is installed on the outer wall. A bracket 45 is installed at the bottom of the base 1, and a turntable 46 fixedly connected to the first motor 31 is rotatably arranged at the center of the bracket 44.

[0041] The second motor 41 rotates the driving gear 42 to push the toothed disk 44 to rotate, so that the rotating ring 43 rotates. Under the connection of the three limit rods 35, the fixed disk 34 rotates and drives the packing box flange to rotate, thereby adjusting the drilling position of the packing box flange. Through the settings of the bracket 45 and the turntable 46, the first motor 31 can work stably.

[0042] As Figure 5 、 Figure 6 、 Figure 7As shown in the figure, the adjustable drilling assembly 5 includes three fixing pieces 51 circumferentially installed on the outer wall of the fixed ring 2. At the top between the three fixing pieces 51, a fixing table 52 is installed. On the fixing table 52, two first electric push rods 53 are installed. Between the output ends of the two first electric push rods 53, a lifting frame 54 is installed. At the bottom of the lifting frame 54, a connecting frame 55 is installed. At both ends of the connecting frame 55, there are two drill rods 56 symmetrically arranged left and right and an adjusting member for adjusting the distance between the two drill rods 56. On the connecting frame 55, there is also a driving member for controlling the synchronous rotation of the two drill rods 56. The driving member includes a double-shaft motor 57 installed on one side of the bottom of the connecting frame 55. At the output end of the double-shaft motor 57, a telescopic rotating rod 58 is installed. At the other end of the telescopic rotating rod 58, a worm 59 is installed. At the upper end of the drill rod 56, a worm gear 510 adapted to the worm 59 is installed. The telescopic rotating rod 58 includes a sleeve 511 installed at the output end of the double-shaft motor 57. At the other end of the sleeve 511, a sliding rod 512 connected to the worm 59 is installed. At one end of the sliding rod 512 located inside the sleeve 511, four guiding blocks 513 are installed. On the four sides of the outer wall of the sleeve 511, there are openings for the front and back sliding of the guiding blocks 513.

[0043] The distance between the two drill rods 56 is adjusted by the adjusting member to correspond to the position to be drilled. Then, the two drill rods 56 are controlled to rotate by the driving member. The drill rods 56 are pushed down by the first electric push rods 53, and thus the packing box flange can be drilled. By cooperating with the rotating adjusting member 4 to rotate the packing box flange, the drilling of the entire circumference of the packing box flange can be achieved, making the drilling distance more accurate. The double-shaft motor 57 drives the telescopic rotating rods 58 on both sides to rotate, driving the worms 59 at both ends to rotate, and pushing the drill rods 56 to rotate through the engagement with the worm gears 510. When the distance between the two drill rods 56 is adjusted, the sliding rod 512 slides inside the sleeve 511. Through the cooperation of the guiding blocks 513 and the openings, the sliding rod 512 will not break away from the sleeve 511, and its movement and rotation are more stable.

[0044] As Figure 6 As shown in the figure, the adjusting member includes a third motor 514 installed on the side wall of the connecting frame 55. At the output end of the third motor 514, a main bevel gear 515 is installed. Inside the connecting frame 55, a bidirectional lead screw 516 is rotatably arranged. On the left and right side walls, moving plates 517 threadedly connected to the bidirectional lead screw 516 are slidably arranged. The moving plates 517 are rotatably connected to the drill rods 56. On the bidirectional lead screw 516, a secondary bevel gear 518 engaged with the main support 515 is installed. At one end of the moving plate 517 located inside the connecting frame 55, two sliding blocks 519 are installed. On the upper and lower side walls of the connecting frame 55, there are notches for the left and right sliding of the sliding blocks 519.

[0045] The third motor 514 drives the main bevel gear 515 to rotate, causing the driven bevel gear 518 to rotate, driving the bidirectional lead screw 516 to rotate, thereby pushing the moving plates 517 on both sides away from or closer to each other, adjusting the distance between the drill pipes 56 on both sides. When the moving plates 517 slide, the sliding blocks 519 at the ends always slide within the notches, making the sliding of the moving plates 517 smoother.

[0046] As Figure 7 shown, the adjustable drilling assembly 5 further includes a fixing bracket 520 installed on the outer wall of the fixing ring 2. The upper end of the fixing bracket 520 is installed with a fourth motor 521. The output end of the fourth motor 521 is installed with an adjusting lead screw 522. Inside the fixing bracket 520, a vertical rod 523 and a moving bracket 524 that is threadedly connected to the adjusting lead screw 522 and slidably connected to the vertical rod 523 are installed. A second electric push rod 525 is installed on the moving bracket 524, and the output end of the second electric push rod 525 is installed with a lateral drilling member 526.

[0047] The drilling member 526 consists of a drilling motor and a drill pipe, which is well-known in the art. By pushing the drilling member 526 towards the side of the stuffing box flange through the second electric push rod 525, the side surface can be drilled. By driving the adjusting lead screw 522 to rotate through the fourth motor 521, under the guidance of the vertical rod 523, the drilling member 526 moves up and down, so that the side surface of the stuffing box flange can be drilled at different heights.
