Technical Field
[0001] This invention relates to a drilling machine for deep hole machining of slurry pumps that facilitates chip removal, and is situated in the field of drilling machines. Background Technology
[0002] As a core piece of equipment in the fluid transport field, the slurry pump's internal deep-hole components are key structures for ensuring the stability and sealing of the medium transport. The quality of deep-hole machining directly affects the assembly accuracy, operating efficiency, and service life of the slurry pump. Deep-hole machining is a difficult process in machining. Because the machining area is in a semi-enclosed, narrow space, it generally suffers from problems such as difficulty in chip removal, poor heat dissipation, and easy vibration of the cutting tool. The high hardness and large depth-to-diameter ratio of the slurry pump workpiece further exacerbate the machining difficulty, placing extremely high demands on the comprehensive performance of the drilling machine in terms of cooling, chip removal, transmission stability, and workpiece clamping.
[0003] During the machining process, existing drilling machines tend to produce metal chips that are long and curled, which are not only difficult to remove smoothly but also easily entangled on the drill bit shaft, causing jamming. Furthermore, conventional external spray coolant delivery methods cannot directly reach the deep hole cutting area, resulting in poor cooling and lubrication. The drill bit remains at a high temperature, accelerating tool wear and annealing failure. At the same time, once chips accumulate and tools become stuck, the cutting resistance increases dramatically. The rigid transmission structure cannot buffer and unload the force, which can easily cause the connecting parts to seize, the transmission shaft to twist and break, and also cause the motor to stall and the coil to overheat and burn out. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention discloses a slurry pump deep hole drilling machine that facilitates chip removal. The machine includes a platform and a U-shaped baffle fixedly connected to the top edge of the platform. The U-shaped baffle provides protection, preventing chips from flying everywhere. A gantry frame is slidably mounted on the top of the platform. A slider is provided on the side of the gantry frame, and a sliding block is provided on the side of the slider near the gantry frame. The sliding block is slidably connected to the slider and the gantry frame.
[0005] Drilling assembly, which is fixedly mounted on the slider;
[0006] The drilling assembly includes a fixing plate, which is fixedly mounted on the slider. A motor is fixedly connected to the top of the fixing plate, and a connector is fixedly connected to the bottom of the fixing plate. A drill bit is fixedly connected to the end of the connector away from the motor.
[0007] Furthermore, the connector includes two connecting blocks. One connecting block is fixedly connected to the output end of the motor, and the other connecting block is fixedly connected to the drill bit. Protrusions and positioning blocks are provided on opposite sides of the two connecting blocks. A clutch-type transmission structure is formed by a spring, an elastic intermediate block, and the protrusions and positioning blocks. Under normal machining conditions, the elastic force of the spring and intermediate block ensures that the two sets of connecting blocks are tightly engaged, and the motor torque is stably transmitted to the drill bit to complete normal drilling operations. When problems such as chip accumulation, drill bit jamming, and a sudden increase in cutting resistance occur during deep hole machining, and the transmission torque exceeds the elastic force threshold, the two connecting blocks can automatically rotate relative to each other, causing the protrusions and positioning blocks to disengage, cutting off power transmission. The drill bit immediately stops rotating, and the motor remains unloaded. This fundamentally avoids the connector from hard-locking and the transmission shaft from twisting and breaking. It also prevents the motor from overheating due to stalling, causing coil burnout and other malfunctions, reducing equipment failure rate and extending the service life of core components. Multiple protrusions and positioning blocks are provided, with each protrusion and positioning block fixedly connected to two connecting blocks.
[0008] Furthermore, a cylindrical body is fixedly connected to the bottom of the fixed plate, and a conical cylinder is slidably connected to the outside of the cylindrical body. The cylindrical body and the conical cylinder are flexibly connected by a bellows. With the help of a guide assembly composed of a round rod and a ring, the conical cylinder can move synchronously with the feed depth of the drill bit, keeping close to the workpiece surface throughout the process. The functions of coolant delivery and chip breaking will not fail as the drilling depth increases. The structure is highly flexible and can meet the deep hole machining needs of slurry pumps of different depths. It has strong versatility. A bellows is sleeved on the outside of the cylindrical body, and the two ends of the bellows are fixed to the cylindrical body and the conical cylinder, respectively. The inner wall of the cylinder is rotatably connected to an inner cylinder, and the inner wall of the inner cylinder is fixedly connected to a side plate. Multiple side plates are evenly distributed on the inner cylinder. A round rod is slidably connected to the outer side of the fixed plate, penetrating the fixed plate. Two round rods are fixedly connected to the bottom of the round rod, evenly distributed on the ring. A spiral groove is formed on the outer side of the drill bit, and the drill bit surface simultaneously has both spiral and axial vertical grooves, forming a dual-channel mechanical chip guide structure. This allows the drill bit to actively push the chips outwards by rotating. Simultaneously, the cylinder, telescopic bellows, and conical cylinder assembly... A flow guide shroud that moves synchronously with the drilling depth, in conjunction with an external connecting pipe to introduce coolant, flushes the interior of the deep hole, accelerates the removal of fine chips, and effectively improves the problems of confined space, chip retention, and poor chip removal in deep hole machining. It avoids repeated chip compression and wear on the hole wall and entanglement of the drill bit, ensuring continuous drilling operations. The drill bit has a vertical groove along its axial direction on its outer side, and a ring tube is installed on the outer side of the tapered cylinder. A connecting pipe is fixedly connected to the outer side of the ring tube of the tapered cylinder. Multiple internal holes are evenly distributed on the inner wall of the bottom of the tapered cylinder. An inclined block is fixedly connected to the bottom outer side of the cylinder. Multiple sets of inclined blocks are evenly arranged at the bottom of the conical cylinder. The long, curled, and continuous chips produced by the drill bit will come into contact with the inclined blocks during the rotation of the drill bit and be sheared and cut into short fragments in real time. This effectively avoids long chips from getting tangled on the drill bit rod and also prevents chips from getting stuck in the machining gap and causing the drill to jam. There is no need to stop the machine frequently to clean the chips manually, which improves the continuity of drilling operations and processing efficiency. It is suitable for long-term, large-volume deep hole machining of slurry pump workpieces. There are multiple inclined blocks, which are evenly distributed on the conical cylinder.
[0009] Furthermore, the connecting block has multiple side grooves evenly distributed on its outer side. Side plates are located inside these grooves. A central cylinder is fixedly connected to the middle of one side of a connecting block equipped with a positioning block. An extension rod is fixedly connected to the middle of one side of a connecting block equipped with a protrusion. The extension rod is located inside the central cylinder. A central block, which is elastic, is located on the outer side of the central cylinder. The central block is positioned between two connecting blocks. An inner cavity is formed at the end of the connecting block furthest from the central block. A limit block, trapezoidal in shape and elastic, is slidably connected inside the inner cavity. The trapezoidal limit blocks inside the connecting block are in close contact with the motor output end and the drill bit end, respectively, constraining the position of the transmission components axially and radially. This, combined with the coaxial positioning of the central cylinder and the extension rod... The positioning structure effectively counteracts radial runout and coaxial deviation caused by high-speed operation of the equipment, reducing operating vibration and noise, and stabilizing the drill bit's operating posture. When machining deep holes for slurry pumps, it effectively ensures the straightness of the borehole and the accuracy of the hole diameter, avoiding machining defects such as hole misalignment and irregular hole walls, thus improving the quality of the finished product. There are multiple limiting blocks, which are evenly distributed on the connecting block. One of the connecting blocks, which is equipped with an intermediate cylinder, has an annular groove on the side near the intermediate cylinder. There are multiple annular grooves, which are evenly distributed on the connecting block. The inner wall of the annular groove is equipped with a spring. The positioning block is slidably connected to the annular groove. The two ends of the spring are fixedly connected to the positioning block and the inner wall of the annular groove, respectively. An extension block is fixedly connected to the outer side of the intermediate block. The extension block is located at the interval between the protrusion and the positioning block.
[0010] Furthermore, the platform includes a frame, with a collection frame fixedly connected to the top of the frame, a base plate fixedly connected to the bottom of the collection frame, and two trapezoidal blocks fixedly connected to the top of the base plate. These two trapezoidal blocks are symmetrically arranged on the base plate. A movable block is located at the top of each trapezoidal block, and a movable rod is slidably connected to the outside of the movable block. The platform is equipped with a flexible clamping mechanism consisting of the movable rod, spring plate, and spheres, which can flexibly clamp the slurry pump workpiece with moderate clamping force. This ensures that the workpiece does not shift or shake during processing, while also avoiding surface damage caused by rigid clamping. The trapezoidal blocks and movable blocks work together to complete auxiliary positioning, ensuring a stable and reliable positioning reference. The number of movable rods... There are multiple moving rods evenly arranged on the moving block. One end of each moving rod is fixedly connected to a spring plate, and the end of the spring plate away from the moving rod is fixedly connected to the moving block. A ball is fixedly connected to the end of the moving rod away from the spring plate. A conical hole is opened at the top of the base plate, and a support block is fixedly connected to the inner wall of the conical hole. The chips generated during processing fall into the collection frame together with the coolant. The conical hole, support block and baffle on the base plate form a graded filtration structure, which can intercept large chips and clumps of debris, allowing only small chips and coolant to pass through, effectively preventing the flow channel from being blocked by large chips. A baffle is fixedly connected to the top of the support block. There are multiple support blocks, and the multiple support blocks are evenly distributed around the baffle.
[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0012] (I) This slurry pump deep hole drilling machine that facilitates chip removal can automatically rotate two connecting blocks when problems such as chip accumulation, drill bit jamming, and sudden increase in cutting resistance occur during deep hole machining, and the transmission torque exceeds the elastic threshold. This causes the protrusion to disengage from the positioning block, cuts off the power transmission, and the drill bit to stop immediately. The motor remains unloaded, thus preventing the connecting parts from hard-locking and the transmission shaft from twisting and breaking, and extending the service life of the core components.
[0013] (II) This slurry pump deep hole drilling machine with easy chip removal has a drill bit surface with both spiral grooves and axial vertical grooves to form a dual-channel mechanical chip guiding structure. The drill bit rotation can actively push the chips outward. At the same time, the cylinder, telescopic bellows and conical cylinder form a guide shroud that can move synchronously with the drilling depth. With the help of the external connecting pipe to introduce coolant, the inside of the deep hole is flushed, and the fine chips are accelerated to be discharged. This effectively improves the problems of closed space, chip retention and poor chip removal in deep hole machining, avoids repeated extrusion and wear of the hole wall by chips and entanglement of the drill bit, and ensures continuous drilling operation.
[0014] (III) This slurry pump deep hole machining drilling machine with easy chip removal has multiple sets of inclined blocks evenly arranged at the bottom of the conical cylinder. The long strips and curled continuous chips generated by the drill bit will come into contact with the inclined blocks during the rotation of the drill bit and be sheared and cut into short fragments in real time. This effectively avoids long chips from getting tangled on the drill bit rod and also prevents chips from getting stuck in the machining gap and causing the drill to jam. There is no need to stop the machine frequently to clean the chips manually, which improves the continuity of drilling operations and processing efficiency. It is suitable for long-term and large-volume deep hole machining of slurry pump workpieces.
[0015] (iv) The slurry pump deep hole drilling machine that facilitates chip removal has the chips and coolant produced during processing falling into the collection frame together. The conical holes, support blocks and baffles on the bottom plate form a graded filtration structure that can intercept large chips and agglomerated debris, allowing only small chips and coolant to pass through, effectively preventing the flow channel from being blocked by large chips.

[0028] Example 1, as Figures 1 to 9 As shown, this embodiment discloses a slurry pump deep hole drilling machine that facilitates chip removal, including a platform 1 and a U-shaped baffle 2 fixedly connected to the top edge of the platform 1. The U-shaped baffle 2 serves as a protective measure to prevent chips from flying everywhere. A gantry frame 3 is slidably installed on the top of the platform 1. A slider 5 is provided on the side of the gantry frame 3. A sliding block is provided on the side of the slider 5 near the gantry frame 3. The sliding block is slidably connected to the slider 5 and the gantry frame 3.
[0029] Drilling assembly 4 is fixedly mounted on slider 5;
[0030] The drilling assembly 4 includes a fixing plate 41, which is fixedly mounted on the slider 5. A motor 42 is fixedly connected to the top of the fixing plate 41, and a connector 45 is fixedly connected to the bottom of the fixing plate 41. A drill bit 47 is fixedly connected to the end of the connector 45 away from the motor 42.
[0031] Connector 45 includes two connecting blocks 451. One connecting block 451 is fixedly connected to the output end of motor 42, and the other connecting block 451 is fixedly connected to drill bit 47. Protrusions 454 and positioning blocks 457 are provided on opposite sides of the two connecting blocks 451. A clutch-type transmission structure is formed by spring 4511, elastic intermediate block 453, protrusions 454, and positioning blocks 457. Under normal machining conditions, the elastic force of spring 4511 and intermediate block 453 ensures that the two sets of connecting blocks 451 are tightly engaged, and the torque of motor 42 is stably transmitted to drill bit 47 to complete normal drilling operations. When deep hole machining causes chip accumulation or drill bit 47 jamming... In the event of a sudden increase in cutting resistance, when the transmission torque exceeds the elastic threshold, the two connecting blocks 451 can automatically rotate relative to each other, causing the protrusion 454 to disengage from the positioning block 457, cutting off the power transmission. The drill bit 47 immediately stops rotating, and the motor 42 remains unloaded. This prevents the connecting parts 45 from seizing rigidly and the transmission shaft from twisting and breaking. It also prevents the motor 42 from overheating due to stalling and the coil from burning out, thus reducing the equipment failure rate and extending the service life of the core components. There are multiple protrusions 454 and positioning blocks 457, which are alternately arranged, and the protrusions 454 and positioning blocks 457 are fixedly connected to the two connecting blocks 451 respectively.
[0032] A cylindrical body 416 is fixedly connected to the bottom of the fixed plate 41. A conical cylinder 43 is slidably connected to the outside of the cylindrical body 416. The cylindrical body 416 and the conical cylinder 43 are flexibly connected by a bellows 413. With the guide assembly composed of a round rod 49 and a ring 410, the conical cylinder 43 can move synchronously with the feed depth of the drill bit, keeping close to the workpiece surface throughout the process. The functions of coolant delivery and chip breaking will not fail as the drilling depth increases. The structure is highly flexible and can meet the deep hole machining needs of slurry pumps of different depths. It has strong versatility. A bellows 413 is sleeved on the outside of the cylindrical body 416. The two ends of the bellows 413 are fixedly connected to the cylindrical body 416 and the conical cylinder 43, respectively. An inner cylinder 44 is rotatably connected to the inner wall of the cylinder 416. Side plates 412 are fixedly connected to the inner wall of the inner cylinder 44. Multiple side plates 412 are evenly distributed on the inner cylinder 44. A round rod 49 is slidably connected to the outer side of a fixed plate 41, penetrating the fixed plate 41. A ring 410 is fixedly connected to the bottom of the round rod 49. There are two round rods 49, evenly distributed on the ring 410. A spiral groove 46 is formed on the outer side of the drill bit 47. The surface of the drill bit 47 simultaneously has the spiral groove 46 and an axial vertical groove 48, forming a dual-channel mechanical chip guide structure. The rotation of the drill bit 47 actively pushes the chips outwards for discharge. Meanwhile, the cylinder... The body 416, the telescopic bellows 413, and the conical cylinder 43 form a flow guide that can move synchronously with the drilling depth. Combined with the external connecting pipe 411, coolant is introduced to flush the inside of the deep hole, accelerating the removal of fine chips. This effectively improves the problems of enclosed space, chip retention, and poor chip removal in deep hole machining, preventing repeated chip compression and wear on the hole wall and entanglement of the drill bit 47, ensuring continuous drilling operations. A vertical groove 48 is formed along the axial direction on the outer side of the drill bit 47. An annular pipe is provided on the outer side of the conical cylinder 43, and a connecting pipe 411 is fixedly connected to the outer side of the annular pipe. Multiple inner holes 415 are formed on the inner wall of the bottom of the conical cylinder 43. Holes 415 are evenly distributed. An inclined block 414 is fixedly connected to the outer bottom of the conical cylinder 43. Multiple sets of inclined blocks 414 are evenly arranged at the bottom of the conical cylinder 43. The long, curled, and continuous chips produced by the drill bit 47 will come into contact with the inclined block 414 during the rotation of the drill bit 47 and be sheared and divided into short fragments in real time. This effectively avoids long chips from getting tangled on the drill bit shaft and also prevents chips from getting stuck in the processing gap and causing the drill to jam. There is no need to stop the machine frequently to clean the chips manually, which improves the continuity of drilling operations and processing efficiency. It is suitable for long-term, large-volume deep hole processing of slurry pump workpieces. There are multiple inclined blocks 414, which are evenly distributed on the conical cylinder 43.
[0033] Example 2, based on Example 1, combined with... Figures 5 to 7As can be seen, a side groove 452 is provided on the outer side of the connecting block 451. There are multiple side grooves 452, which are evenly distributed on the connecting block 451. The side plate 412 is located inside the side groove 452. A middle cylinder 458 is fixedly connected to the middle of one side of a connecting block 451 with a positioning block 457. An extension rod 459 is fixedly connected to the middle of one side of a connecting block 451 with a protrusion 454. The extension rod 459 is located inside the middle cylinder 458. A middle block 45 is provided on the outer side of the middle cylinder 458. 3. The intermediate block 453 is elastic and is located at the interval between the two connecting blocks 451. An inner cavity 455 is formed inside the connecting block 451 at the end furthest from the intermediate block 453. A limit block 456 is slidably connected inside the inner cavity 455. The limit block 456 is trapezoidal and elastic. The trapezoidal limit block 456 inside the connecting block 451 is in close contact with the output end of the motor 42 and the end of the drill bit 47, respectively, constraining the position of the transmission components in both axial and radial directions. This works in conjunction with the intermediate cylinder 458 and... The coaxial positioning structure of the extension rod 459 can effectively counteract the radial runout and coaxial deviation generated by the high-speed operation of the equipment, reduce operating vibration and noise, and stabilize the drill bit's operating posture. When machining deep holes for slurry pumps, it can effectively ensure the straightness of the borehole and the accuracy of the hole diameter, avoiding machining defects such as hole misalignment and irregular hole walls, thus improving the quality of the finished product. Multiple limit blocks 456 are evenly distributed on the connecting block 451, which is equipped with an intermediate cylinder 458. A ring groove 4510 is provided on one side near the intermediate cylinder 458. There are multiple ring grooves 4510, which are evenly distributed on the connecting block 451. A spring 4511 is provided on the inner wall of the ring groove 4510. The positioning block 457 is slidably connected to the ring groove 4510. The two ends of the spring 4511 are fixedly connected to the positioning block 457 and the inner wall of the ring groove 4510, respectively. An extension block 4512 is fixedly connected to the outer side of the intermediate block 453. The extension block 4512 is located at the interval between the protrusion 454 and the positioning block 457.
[0034] Example 3, based on Examples 1 and 2, combined with... Figures 10 to 11Platform 1 includes a frame 11, with a collection frame 13 fixedly connected to the top of the frame 11, a base plate 19 fixedly connected to the bottom of the collection frame 13, and a trapezoidal block 12 fixedly connected to the top of the base plate 19. There are two trapezoidal blocks 12 symmetrically arranged on the base plate 19. A movable block 16 is located at the top of each trapezoidal block 12, and a movable rod 14 is slidably connected to the outer side of the movable block 16. Platform 1 is equipped with a movable rod 14, a spring plate 17, and a ball 15 forming an elastic clamping mechanism, which can flexibly clamp the slurry pump workpiece with moderate clamping force. This ensures that the workpiece does not shift or shake during processing, while also avoiding surface damage caused by rigid clamping. The trapezoidal block 12 and movable block 16 work together to complete auxiliary positioning, ensuring a stable and reliable positioning reference. Multiple movable rods 14 are present. Rods 14 are evenly arranged on the moving block 16. One end of the moving rod 14 is fixedly connected to a spring plate 17. The end of the spring plate 17 away from the moving rod 14 is fixedly connected to the moving block 16. The end of the moving rod 14 away from the spring plate 17 is fixedly connected to a ball 15. A conical hole 111 is opened on the top of the base plate 19. A support block 110 is fixedly connected to the inner wall of the conical hole 111. The chips generated during processing fall into the collection frame 13 together with the coolant. The conical hole 111, the support block 110 and the baffle 18 on the base plate 19 form a graded filtration structure, which can intercept large chips and clumps of debris, and only allow small chips and coolant to pass through, effectively preventing the flow channel from being blocked by large chips. A baffle 18 is fixedly connected to the top of the support block 110. There are multiple support blocks 110, and the multiple support blocks 110 are evenly distributed around the baffle 18.
[0035] In use, the workpiece to be processed by the slurry pump is placed in the positioning area of the platform 1, and the moving blocks 16 on both sides move relative to each other in the direction of the workpiece, so that the spheres 15 on the moving blocks 16 come into contact with the workpiece, and the spring plate 17 is deformed by force, so that the multiple spheres 15 on both sides clamp and fix the workpiece.
[0036] After the workpiece is fixed, the gantry 3 slides laterally along the platform 1. The sliding block drives the entire drilling assembly 4 to move longitudinally, precisely adjusting the machining position of the drill bit 47 and the workpiece. Then, the slider 5 drives the drill bit 47 to move downward. At the same time, the motor 42 operates and outputs torque. The power is transmitted to the drill bit 47 through the connector 45 composed of two sets of connecting blocks 451. The trapezoidal limiting blocks 456 inside the connecting blocks 451 are tightly attached to the motor output end and the drill bit end, respectively, constraining the position of the components axially and radially and ensuring the coaxiality of the transmission. The staggered protrusions 454 and positioning blocks 457 between the connecting blocks 451 use the elastic force of the spring 4511 and the elastic intermediate block 453 to keep the connecting blocks 451 in place under normal load. 1. Tight fit ensures normal power transmission. When deep hole machining encounters situations such as chip blockage or drill bit 47 jamming, and the transmission torque exceeds the elastic limit of spring 4511 and intermediate block 453, positioning block 457 will overcome the tension of spring 4511 inside annular groove 4510, intermediate block 453 will deform and slide away from protrusion 454, and connecting blocks 451 on both sides will overcome the elastic force and rotate relative to each other, causing protrusion 454 and positioning block 457 to disengage from the original interlocking state, interrupting power transmission and stopping drill bit 47, thus preventing connecting part 45 from being rigidly locked. At this time, motor 42 can maintain normal idling and will not experience malfunctions such as machine jamming or burnout due to sudden increase in load.
[0037] Motor 42 drives drill bit 47 to rotate synchronously and feed downwards. The spiral groove 46 and axial vertical groove 48 on the surface of drill bit 47 form a double chip removal channel. The metal chips generated during processing are conveyed upwards by the rotation of the drill bit. The inner hole 415 on the conical cylinder 43, together with the external connecting pipe 411 and the ring pipe, introduces coolant. The coolant flows out from the inner hole 415 of the conical cylinder 43 and flows along the spiral groove 46 and axial vertical groove 48 on the outside of drill bit 47. The chips in the hole are carried out by the flushing action of the liquid, achieving efficient chip removal. The inclined blocks 414 evenly arranged at the bottom of the conical cylinder 43 can cut and cut long strips and curled chips, dividing long chips into small fragments, effectively preventing chips from wrapping around the surface of drill bit 47, ensuring continuous drilling operation. The round rod 49 and the ring 410 can guide the stroke, ensuring that it can flexibly extend and retract with the drilling depth and always stay close to the processing surface, preventing chips from overflowing.
[0038] The discharged debris falls into the collection frame 13. The conical hole 111 on the bottom plate 19, together with the inner support block 110 and the baffle 18, forms a filter structure that can intercept large metal debris, filter fine impurities, achieve solid-material separation, and prevent debris from clogging the channel.
