Description

Technical Field

[0001] This utility model relates to the field of deep hole boring technology for mud pump housings, specifically a device for deep hole boring of mud pump housings. Background Technology

[0002] The mud pump casing consists of a volute, an inlet section, and an outlet section. The inlet section is a straight pipe with a precision cylindrical hole inside for mounting bearings and supporting the pump shaft. The inlet section requires boring using a deep hole boring machine to create the precision cylindrical hole.

[0003] A deep hole boring device for machining mud pump housings typically consists of the following main components: a boring machine, a spindle, a boring bar, and a boring tool. Its working principle is as follows: First, the mud pump housing is mounted on the boring machine and securely fixed with a clamp to ensure its stable position. Then, the spindle is started, and the boring bar drives the boring tool to rotate and feed. The boring tool cuts on the mud pump housing, gradually machining the required deep hole shape and size. Through these steps, the deep hole boring device for machining mud pump housings can efficiently and accurately machine the required deep hole structure, meeting the usage requirements of the mud pump.

[0004] Existing deep hole boring devices require segmented boring during the deep hole machining of mud pump housings. After each segment retracts, the chips are guided out through the grooves on the boring bar. However, the chip removal volume is small, and the chips tend to accumulate in the bore, resulting in poor chip removal efficiency of the device. Therefore, a deep hole boring device for mud pump housing machining is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes a device for boring deep holes in mud pump housing.

[0006] The technical solution adopted by this utility model to solve its technical problem is a device for boring deep holes in mud pump housings, including a boring machine, a PLC controller installed on the side wall of the boring machine, and a boring assembly installed on the boring machine; the boring assembly includes a hydraulic cylinder, the hydraulic cylinder is fixedly installed on the boring machine via a fixed base, a movable frame is installed on the actuating rod of the hydraulic cylinder, a drive motor is installed on the movable frame, a rotating rod is installed on the output shaft of the drive motor, a boring bar is fixedly connected to the other end of the rotating rod, a rod seat is installed on the movable frame, the boring bar is rotatably connected to the rod seat, a rod hole is opened in the boring bar, the rotating rod is fixedly connected to the inner wall of the rod hole, and the boring bar has... A boring bar is installed, and an electromagnet is fixedly mounted on the rod holder. The outer wall of the electromagnet is in contact with the inner wall of the rod hole. The electromagnet is connected to a PLC controller through an internal circuit. After the first stage of boring of the deep hole is completed, the electromagnet is energized to generate a magnetic field, which magnetizes the boring bar and boring bar, thereby attracting iron chips. Then, the boring bar and boring bar move horizontally from the deep hole, and the scraper scrapes off the iron chips attracted to the surface of the boring bar. When they are completely removed from the deep hole, the electromagnet is de-energized and the magnetic field disappears. The remaining iron chips on the boring bar and boring bar will automatically fall off. This structure can attract and discharge a large amount of chips in the deep hole, increase the chip removal volume, avoid chip accumulation in the boring hole, and improve the chip removal efficiency of the device.

[0007] Preferably, a guide ring is fixedly mounted on the boring machine via a mounting base. A scraper is mounted on the side wall of the guide ring. The scraper has a ring structure, and its inner wall is in contact with the outer wall of the boring bar. Multiple circular holes are formed inside the guide ring, and ball bearings are rotatably mounted within these holes. The ball bearings are in contact with the outer wall of the boring bar. A positioning seat is mounted on the boring machine, and a placement groove is installed within the positioning seat. An inlet section structure is placed in the placement groove, and four sets of triangular blocks are mounted on the outer wall of the inlet section structure. The shape of the placement groove matches the shape of the inlet section structure, and the boring machine is symmetrical. Two mounting plates are installed, and two screws are fixedly mounted on the mounting plates. A pressure plate is slidably sleeved on the screw, and an anti-slip washer is sleeved on the screw. A nut is threaded around the screw. When the boring bar drives the boring tool to rotate and feed, a guide ring limits the movement of the boring bar to prevent it from wobble, which would then cause the boring tool to wobble. By setting ball bearings in the guide ring, the friction between the guide ring and the boring bar can be effectively reduced. This structure can provide auxiliary support for the boring bar, prevent the boring tool from wobble, and improve the stability of the boring tool.

[0008] The advantages of this utility model are:

[0009] 1. This utility model utilizes an electromagnet to generate a magnetic field after the first stage of boring of a deep hole is completed. The boring bar and boring tool are magnetized, thus attracting iron chips. Then, the boring bar and boring tool move horizontally from the deep hole, and a scraper removes the iron chips attracted to the surface of the boring bar. When they are completely removed from the deep hole, the electromagnet is de-energized and the magnetic field disappears. The remaining iron chips on the boring tool and boring bar will automatically fall off. This structure can attract and discharge a large amount of chips in the deep hole, increasing the chip removal volume and preventing chips from accumulating in the boring hole, which is beneficial to improving the chip removal efficiency of the device.

[0010] 2. In this invention, when the boring bar drives the boring tool to rotate and feed, the guide ring limits the boring bar to prevent it from wobble, which in turn causes the boring tool to wobble. By setting ball bearings in the guide ring, the friction between the guide ring and the boring bar can be effectively reduced. This structure can provide auxiliary support for the boring bar, prevent the boring tool from wobble, and improve the stability of the boring tool. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-2 As shown, a device for boring deep holes in a mud pump housing includes a boring machine 1, a PLC controller 2 mounted on the side wall of the boring machine 1, and a boring assembly mounted on the boring machine 1. The boring assembly includes a hydraulic cylinder 3, which is fixedly mounted on the boring machine 1 via a fixed base. A movable frame 301 is mounted on the actuating rod of the hydraulic cylinder 3, and a drive motor 302 is mounted on the movable frame 301. A rotating rod 303 is mounted on the output shaft of the drive motor 302, and a boring bar 304 is fixedly connected to the other end of the rotating rod 303. A rod holder 305 is mounted on the movable frame 301, and the boring bar 304 is rotatably connected to the rod holder 305. A rod hole is opened in the boring bar 304, and the rotating rod 303 is fixedly connected to the inner wall of the rod hole. A boring tool 306 is mounted on the boring bar 304, and an electromagnet 4 is fixedly mounted on the rod holder 305. The outer wall of the electromagnet 4 is flush with the inner wall of the rod hole. In conjunction with this, electromagnet 4 is connected to PLC controller 2 via internal circuitry. During operation, existing deep hole boring devices require segmented boring during the deep hole boring process of mud pump housing. After each segment retracts, the chips are guided out through the grooves on the boring bar 304. However, the chip removal volume is small, and the chips tend to accumulate in the boring hole, resulting in poor chip removal efficiency of the device. Mud pumps are machines that transport mud or flushing fluids such as water into the borehole during drilling. The mud pump housing consists of a volute, an inlet section structure 7, and an outlet section structure. The two ends of the inlet section structure 7 are fixedly connected to the volute and the outlet section structure, respectively. The inlet section structure 7 is a straight tube structure with a precision cylindrical hole inside for installing bearings and supporting the pump shaft. The inlet section structure 7 needs to be bored using a deep hole boring device to bore a precision cylindrical hole.

[0020] By placing the inlet section structure 7 in the placement groove of the positioning seat 6, the shape of the placement groove is adapted to the shape of the inlet section structure 7. Therefore, the deep hole boring device is only compatible with one type of mud pump housing. Since four sets of triangular blocks 701 are installed on the inlet section structure 7, and the triangular blocks 701 of the inlet section structure 7 are locked on the positioning seat 6, rotation of the inlet section structure 7 during deep hole boring can be prevented. Since the two pressure plates 603 are slidably sleeved on the screws 602, the two pressure plates 603 contact the top side of the inlet section structure 7, and then the four screws 602 are rotated. The nut 605 moves linearly through rotation, thereby pressing and tightening the pressure plate 603. When the nut 605 is tightened, the two pressure plates 603 press and fix the inlet section structure 7, thus clamping and fixing the inlet section structure 7. The combination of nut 605 and screw 602 has self-locking property. When the thread helix angle is less than the friction angle, sliding friction will cause the nut 605 to self-lock. In addition, it is equipped with anti-slip pads 604, so the vertical force applied by the inlet section structure 7 will not cause the nut 605 to loosen.

[0021] When boring deep holes in the inlet section structure 7, the PLC controller 2 controls the drive motor 302 to operate, which drives the rotating rod 303 to rotate. The rotating rod 303 drives the boring bar 304 to rotate at high speed, and the boring bar 304 drives the boring tool 306 to rotate at high speed. At the same time, the hydraulic cylinder 3 operates, and its action rod drives the moving frame 301, rod seat 305, boring bar 304, and boring tool 306 to move horizontally in sync. This realizes that the boring bar 304 drives the boring tool 306 to rotate and feed, so that the boring tool 306 cuts on the inlet section structure 7 and gradually processes the required deep hole shape.

[0022] During this process, segmented boring is required. The deep hole is machined in four segments, with each segment involving tool retraction and chip removal to prevent chip blockage. After the first segment of boring is completed, the PLC controller 2 stops the drive motor 302, and the boring bar 304 and boring tool 306 stop rotating. The boring tool 306 and boring bar 304 remain inside the deep hole. Then, the PLC controller 2 energizes the electromagnet 4, which generates a magnetic field. Since the boring bar 304 and boring tool 306 are made of metal, they are magnetized and attract iron chips. Subsequently, the actuator on the hydraulic cylinder 3 pulls the boring tool 304... 6. The boring bar 304 moves horizontally from the deep hole. During this process, the scraper 401 scrapes off the iron filings adsorbed on the surface of the boring bar 304. When the boring bar 306 and the boring bar 304 are completely removed from the deep hole, the PLC controller 2 stops energizing the electromagnet 4. After the electromagnet 4 is de-energized, the magnetic field disappears, and the remaining iron filings on the boring bar 306 and the boring bar 304 will automatically fall off, realizing the discharge of chips from the deep hole. This structure can adsorb and discharge a large amount of chips from the deep hole, increasing the chip discharge volume and preventing chips from accumulating in the boring hole, which is conducive to improving the efficiency of chip removal of the device.

[0023] Please see Figure 3-5 As shown, a guide ring 5 is fixedly mounted on the boring machine 1 via a mounting base. A scraper 401 is mounted on the side wall of the guide ring 5. The scraper 401 has a ring structure, and its inner wall is in contact with the outer wall of the boring bar 304. Multiple circular holes are opened in the guide ring 5, and ball bearings 501 are rotatably installed in the circular holes. The ball bearings 501 are in contact with the outer wall of the boring bar 304. A positioning seat 6 is mounted on the boring machine 1. A placement groove is installed in the positioning seat 6, and an inlet section structure 7 is placed in the placement groove. Four sets of triangular blocks 701 are installed on the outer wall of the inlet section structure 7. The shape of the placement groove is adapted to the shape of the inlet section structure 7. Two mounting plates 601 are symmetrically mounted on the boring machine 1. Two screws 602 are fixedly mounted on the mounting plates 601. A pressure plate 603 is slidably sleeved on the screws 602, and an anti-slip pad 604 is sleeved on the screws 602. A nut 605 is threaded around the screw 602. During operation, existing deep-hole boring devices struggle to provide auxiliary support for the boring bar 304 during deep-hole machining of the mud pump housing, leading to easy wobble of the boring tool 306 and poor stability. By adding a guide ring 5, the boring bar 304 is limited when it drives the boring tool 306 to rotate and feed, preventing wobble and thus avoiding wobble of the boring tool 306. This effectively limits the movement of the boring bar 304. By incorporating ball bearings 501 within the guide ring 5, the friction between the guide ring 5 and the boring bar 304 is effectively reduced. This structure provides auxiliary support for the boring bar 304, preventing wobble of the boring tool 306 and improving its stability.

[0024] Working principle: Existing deep hole boring devices require segmented boring during the deep hole machining of mud pump housings. After each segment retraction, the chips are guided out through grooves on the boring bar 304. However, the chip removal volume is small, and chips tend to accumulate in the borehole, resulting in poor chip removal efficiency and affecting the accuracy of deep hole boring. A mud pump is a machine that delivers mud or water flushing fluid into the borehole during drilling. The mud pump housing consists of a volute, an inlet section structure 7, and an outlet section structure. The inlet section structure 7 is fixedly connected to the volute and outlet section structure at both ends, respectively. The inlet section structure 7 is a straight pipe structure with internal precision... The inlet section structure 7 has a tight cylindrical hole for mounting bearings and supporting the pump shaft. It requires a deep-hole boring device to bore this precision cylindrical hole. The inlet section structure 7 is placed in the mounting groove of the positioning seat 6, the shape of which matches the shape of the inlet section structure 7. Therefore, the deep-hole boring device is only suitable for one type of mud pump housing. Because four sets of triangular blocks 701 are installed on the inlet section structure 7, and these blocks are engaged with the positioning seat 6, rotation of the inlet section structure 7 during deep-hole boring is prevented. Since the two pressure plates 603 are slidably fitted onto the screw 602, therefore… Two pressure plates 603 contact the top side of the inlet section structure 7. Then, the nuts 605 on the four screws 602 are rotated. The nuts 605 move linearly through rotation, thus tightening and pressing the pressure plates 603. When the nuts 605 are tightened, the two pressure plates 603 press and fix the inlet section structure 7, achieving clamping and fixing. The combination of nuts 605 and screws 602 has self-locking properties. When the thread helix angle is less than the friction angle, sliding friction will cause the nuts 605 to self-lock. Furthermore, anti-slip pads 604 are installed, so the vertical force applied to the inlet section structure 7 will not drive it. Nut 605 becomes loose; during the deep hole boring process of the inlet section structure 7, the PLC controller 2 controls the drive motor 302 to operate, which drives the rotating rod 303 to rotate. The rotating rod 303 drives the boring bar 304 to rotate at high speed, and the boring bar 304 drives the boring tool 306 to rotate at high speed. At the same time, the hydraulic cylinder 3 operates, and its action rod drives the moving frame 301, rod seat 305, boring bar 304, and boring tool 306 to move horizontally in sync. This enables the boring bar 304 to drive the boring tool 306 to rotate and feed, so that the boring tool 306 cuts on the inlet section structure 7 and gradually processes the required deep hole shape.This process requires segmented boring, machining the deep hole in four segments. Each segment involves retracting the tool to remove chips and prevent clogging. After the first segment of boring is completed, the PLC controller 2 stops the drive motor 302, halting the rotation of the boring bar 304 and boring tool 306. The boring tool 306 and boring bar 304 remain inside the deep hole. Then, the PLC controller 2 energizes the electromagnet 4, generating a magnetic field. The boring bar 304 and boring tool 306 are made of metal... The material is magnetized, attracting iron filings. Then, the actuator on hydraulic cylinder 3 pulls the boring bar 306 and boring bar 304 horizontally from the deep hole. During this process, scraper plate 401 scrapes off the iron filings attracted to the surface of boring bar 304. Once the boring bar 306 and boring bar 304 are completely removed from the deep hole, PLC controller 2 stops energizing electromagnet 4. After electromagnet 4 is de-energized, the magnetic field disappears, and the remaining iron filings on the boring bar 306 and boring bar 304 automatically fall off, achieving... For chip removal from deep holes, this structure can adsorb and remove a large amount of chips, increasing the chip removal volume and preventing chip accumulation in the boring hole, which is beneficial to improving the chip removal efficiency of the device. In existing deep hole boring devices, during the deep hole machining of mud pump housings, it is difficult to provide auxiliary support for the boring bar 304, and the boring tool 306 is prone to wobble, resulting in poor stability of the boring tool 306. By adding a guide ring 5, the boring bar 304 drives the boring tool 306... During the rotation and feed motion of the boring bar 304, the guide ring 5 limits its movement to prevent it from wobbling, which in turn would cause the boring tool 306 to wobble. This effectively limits the movement of the boring bar 304. By incorporating ball bearings 501 within the guide ring 5, the friction between the guide ring 5 and the boring bar 304 is effectively reduced. This structure provides auxiliary support for the boring bar 304, preventing the boring tool 306 from wobble and improving its stability.
