Description

Technical Field

[0001] The invention relates to the technical field of drill rod processing, in particular to a drill rod processing and cutting device. Background Art

[0002] Drill rod is a tool widely used in engineering fields such as drilling, mining, and construction. It generally consists of a drill tail, a drill body, and a drill bit. The drill rod is a rod-shaped component connected to a rock drill or other drilling equipment, used to transmit impact energy and torque to drive the drill bit to drill rocks. During operation, it withstands high-frequency impact loads, torque, and friction, and is one of the key components for achieving drilling operations. When the rock drill is operating, the piston performs high-frequency reciprocating motion, transferring the impact energy through the drill tail. The drill rod then transfers the energy to the drill bit, causing the drill bit to impact the rock at a high frequency. At the same time, the drill rod rotates driven by the rotary mechanism, causing the drill bit to cut the rock while impacting it, thereby breaking the rock and forming a drill hole. During the drilling process, high-pressure water or compressed air introduced through the center hole of the drill rod expel rock cuttings from the hole to ensure smooth drilling.

[0003] During the processing of drill rods, the blanks after material selection and cutting will be forged to initially form the shape of the drill rods. The forged blanks are then cut on a lathe. The drill rod cutting process includes turning, milling and drilling of the rod material, so that the drill rod blanks are processed into products that meet the design requirements through the cutting process.

[0004] At present, when machining and cutting drill rods, flat pin grooves are machined on the surface of the drill rods to provide installation positions for the flat pins, ensuring accurate installation and positioning of the drill rods on equipment such as breakers. Such flat pin grooves are usually machined using a milling machine with an end mill clamped. When machining drill rods, the worktable surface of the milling machine is usually equipped with a multi-section support seat supplemented by a clamping structure to clamp the drill rod during machining. The multi-section support fixture needs to adjust the position and clamping force of each support section one by one, and the clamping operation is inconvenient. Moreover, since the multi-section support fixture is a segmented support, there may be slight movement errors between the support sections. These errors will accumulate during drill rod machining, and ultimately affect the cutting accuracy of the drill rod when machining the flat pin groove. For this reason, we propose a drill rod machining and cutting device. Summary of the Invention

[0005] The main purpose of the present invention is to provide a drill rod processing and cutting device, by arranging a supporting clamping mechanism and a pressing clamping mechanism on the workbench of the milling machine body, through the cooperation of the supporting clamping mechanism and the pressing clamping mechanism, the drill rod receiving groove of the supporting clamping die and the pressing clamping die is formed into a whole-root clamping structure, replacing the traditional segmented support clamp, the rotary bolts at both ends of the supporting clamping die initially clamp and position the drill rod, and the opposing pressure tooth blocks of the pressing mechanism realize multi-point secondary pressing through the oblique windows, avoiding the accumulation of movement errors of the segmented support, and ensuring that the drill rod is stable and has no offset movement during processing. The whole-root clamping design fundamentally improves the positioning accuracy during flat pin groove cutting, and solves the processing error problem caused by segmented adjustment and support gap of traditional clamps. The lifting and clamping mechanism drives the pressing clamping die to rise and fall through the hydraulic lifting cylinder, and cooperates with the positioning clamping of the trapezoidal lifting groove and the trapezoidal lifting bar to realize rapid docking and separation of the pressing clamping die and the supporting clamping die. There is no need to adjust the support segments one by one during clamping. The lifting and lowering of the pressing clamping die and the multi-point pressure of the pressing mechanism can be completed by one click through the hydraulic system, which significantly simplifies the operation process and can effectively solve the problems in the background technology.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] A drill rod processing and cutting device includes a milling machine body, a workbench with T-shaped grooves on the surface of the movable table of the milling machine body is fixed, and also includes a supporting and clamping mechanism, a pressing and clamping mechanism, a lifting and clamping mechanism and a pressing and resisting mechanism. The workbench surface is equipped with a supporting and clamping mechanism for supporting the drill rod for double-end clamping, and a pressing and clamping mechanism is installed on the supporting and clamping mechanism through the lifting and clamping mechanism to cooperate with the supporting and clamping mechanism to clamp the entire drill rod. A pressing and resisting mechanism is installed on the top of the pressing and clamping mechanism for pressing the drill rod downward at multiple points. The pressing and clamping mechanism is lifted and lowered by the lifting and clamping mechanism to facilitate the removal of the processed drill rod.

[0008] Furthermore, the supporting clamp mechanism includes a base plate, a lifting and locking block, a supporting clamping die and a screw-in bolt, the plate body of the base plate is installed at the T-slot of the workbench through the lifting and locking block and the flange nut, and the surface of the base plate between the lifting and locking blocks is welded with a supporting clamping die, a drill rod accommodating groove is provided in the die body of the supporting clamping die, and circular convex parts and block convex parts are protruded upward at the die heads at both ends of the supporting clamping die, screw-in holes that communicate with the drill rod accommodating groove inside the supporting clamping die are provided at the circular convex parts and the block convex parts, and screw-in bolts for pressing the two ends of the drill rod are screwed into the screw-in holes, and side milling windows for the end mill cutter to extend into the die for cutting processing are symmetrically provided at the die body of the supporting clamping die near the circular convex parts;

[0009] By adopting the above-mentioned preferred technical solution, after the base plate is embedded in the T-slot of the workbench with the help of the lifting and locking block and the flange nut, the support clamping die on the surface of the base plate can accommodate half of the rod body of the drill rod with the help of its own drill rod accommodating groove. At this time, the drill tail and the drill head of the drill rod are respectively against the circular convex part and the block convex part, and then the screw-in bolts are screwed into the screw bottom holes of the circular convex part and the block convex part, so as to symmetrically press the drill rod in the support clamping die for initial clamping and positioning, and ensure that the rod body of the drill rod used for processing the flat pin groove is at the side milling machine of the support clamping die.

[0010] Furthermore, a side mounting groove is formed in a recessed manner at a plate surface of the base plate near the side milling window, and a curved nozzle for connecting to an external cooling liquid supply pipe to spray coolant into the side milling window is inserted into the side mounting groove, and a bottom column is welded to the outer bend of the curved nozzle, and a column hole for clamping the bottom column is formed in the bottom groove wall of the side mounting groove;

[0011] By adopting the above-mentioned preferred technical solution, after the tube body of the curved nozzle is inserted into the side mounting groove of the base plate, the curved nozzle is clamped and positioned in the column hole of the side mounting groove with the bottom column, and then the bottom tube body of the curved nozzle can be screwed to some tube bodies with threaded accessories to connect to the liquid pump for extracting coolant to obtain coolant, so that the coolant can be sprayed along the curved nozzle toward the side milling window of the support clamping mold, thereby effectively cooling the drill rod in the cutting process in a downward inclined side spray manner.

[0012] Furthermore, a through hole is formed on the surface of the base plate away from the support mold, and a bolt welded on the top of the lifting and locking block passes out of the through hole and is screwed to the flange nut, and the T-shaped block of the lifting and locking block is clamped into the T-shaped slot of the workbench;

[0013] By adopting the above-mentioned preferred technical solution, the bolts of the lifting and locking block can be passed upward through the through-holes of the base plate and then the flange nuts can be screwed on for connection. Then the T-shaped block of the lifting and locking block can be clamped into the T-slot of the workbench for clamping. When the base plate slides on the surface of the workbench to a position suitable for processing the drill rod, the flange nut is tightened with a wrench so that the lifting and locking block is lifted and clamped in the T-slot, thereby locking the base plate to the surface of the workbench.

[0014] Furthermore, a clamping mechanism is pressed on the top of the support die above the base plate, and the clamping mechanism includes a clamping die, an oblique window and a trapezoidal groove. The clamping die is pressed on the top of the support die, and a drill rod receiving groove for clamping the drill rod is provided on the lower die surface of the clamping die. The bottom surface of the die body at both ends of the clamping die away from the drill rod receiving groove in the die is symmetrically provided with an arc fixing groove and a fixed block groove, and a circular convex portion and a block convex portion are respectively clamped in the arc fixing groove and the fixed block groove. The clamping die is symmetrically provided with side milling windows on the die body near the arc fixing groove, and three groups of window grooves of oblique windows are symmetrically provided on the die body surface of the clamping die away from its own side milling windows.

[0015] By adopting the above-mentioned preferred technical solution, when the pressing mold is placed on the surface of the supporting mold, the pressing mold is clamped and positioned with the arc fixed groove and the fixed block groove and the circular convex part and the block convex part of the supporting mold, so that the drill rod receiving groove of the pressing mold can cooperate with the drill rod receiving groove of the supporting mold to clamp the drill rod, and the three groups of window grooves on the surface of the pressing mold obliquely facing the window can pass through the pressure tooth block of the pressing mechanism.

[0016] Furthermore, a pressing mechanism is installed on the surface of the clamping die on the outer side of the diagonally opposite window, and the pressing mechanism includes a pressure tooth block, a bridge plate, a pressure connecting plate B, a hydraulic cylinder, a notch support plate B and a vertical bending frame B. The pressure tooth block is symmetrically welded to the lower surface of the bridge plate, and the pressure tooth block is inserted into the drill rod receiving groove of the clamping die along the diagonally opposite window. The top of the bridge plate is locked with the pressure connecting plate B by bolts, and the pressure connecting plate B is welded to the telescopic rod head of the hydraulic cylinder. The cylinder body of the hydraulic cylinder is locked to the top of the notch support plate B by bolts, and the vertical bending frame B is welded to one side of the plate body of the notch support plate B. The bottom frame plate of the vertical bending frame B is locked to the surface of the clamping die on the outer side of the diagonally opposite window by bolts, and the telescopic rod of the hydraulic cylinder passes through the notch groove of the notch support plate B.

[0017] By adopting the above-mentioned preferred technical solution, after the vertical bending frame B of the pressing mechanism is installed on the surface of the clamping die near the diagonally opposite window, the telescopic rod of the hydraulic cylinder can be inserted into the notch groove of the notch support plate B, and then the notch support plate B above the vertical bending frame B can be used to lock the cylinder body outer disc seat of the hydraulic cylinder with the help of bolts. At this time, there is a pressing plate B under the telescopic rod of the hydraulic cylinder, which can be connected to the bridge plate with bolts, making it convenient for the hydraulic cylinder to drive the bridge plate to rise and fall, so that the pressure tooth block under the bridge plate can enter the drill rod groove of the clamping die along the diagonally opposite window to perform secondary pressure on the drill rod.

[0018] Furthermore, a lifting and clamping mechanism is installed between the clamping die and the base plate, and the lifting and clamping mechanism includes a pressing plate A, a hydraulic lifting cylinder, a notched supporting plate A, a vertical bending frame A, a counter-pressure tooth block and a bridge plate. The side plate surface of the base plate close to the circular convex portion and the block convex portion of the top of the clamping die is symmetrically locked with the bottom plate of the vertical bending frame A by bolts, and the notched supporting plate A is welded at the upper bending plate of the vertical bending frame A. The notched supporting plate A is locked with a hydraulic lifting cylinder by bolts, and the telescopic rod head of the hydraulic lifting cylinder passes through the notched supporting plate A and is welded with the pressing plate A. The pressing plate A is locked to both ends of the top die body of the clamping die by bolts;

[0019] By adopting the above-mentioned preferred technical solution, after the pressing plate A of the lifting and clamping mechanism is locked on the surface of the pressing die by bolts, the hydraulic lifting cylinder welded to the pressing plate A can be locked on the notch support plate A with the help of bolts, so that the telescopic rod of the hydraulic lifting cylinder can be raised and lowered at the notch support plate A. At the same time, the vertical bending frame A on one side of the notch support plate A can be locked on the surface of the base plate with the help of bolts to obtain support, so that the lifting and clamping mechanism can drive the pressing die to be raised and lowered.

[0020] Furthermore, the clamping die is symmetrically provided with trapezoidal lifting grooves for clamping the trapezoidal lifting strips at the two end mold bodies near the pressing plate A, and the trapezoidal lifting strips are centrally welded below the pressing plate A;

[0021] By adopting the above-mentioned preferred technical solution, when the pressing plate A is fastened to the clamping die with bolts, the pressing plate A can be clamped in the trapezoidal lifting groove of the clamping die with the help of the trapezoidal lifting bar for positioning, and the interlocking connection between the trapezoidal lifting bar and the trapezoidal lifting groove can also enhance the connection stability and firmness between the pressing plate A and the clamping die, ensuring that the clamping die can be lifted and lowered stably.

[0022] Furthermore, a fixed plate for inserting the block protrusion is symmetrically protruded in the fixed block groove of the clamping die, and a rectangular fixed groove for clamping the fixed plate is staggered at the top of the block protrusion;

[0023] By adopting the above-mentioned preferred technical solution, after the fixed block groove of the clamping die is clamped with the block protrusion, the fixed plate in the fixed block groove is inserted into the rectangular fixed groove of the block protrusion for secondary positioning connection, thereby ensuring the precise guiding docking of the clamping die and the supporting die, and ensuring that the clamping die and the supporting die can stably clamp the drill rod.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention provides a supporting clamping mechanism and a pressing clamping mechanism on the worktable of the milling machine body. Through the cooperation of the supporting clamping mechanism and the pressing clamping mechanism, a whole-root clamping structure is formed with the drill rod receiving grooves of the supporting clamping die and the pressing clamping die, thereby replacing the traditional segmented support fixture. The rotary bolts at both ends of the supporting clamping die initially clamp and position the drill rod, and the counter-pressure tooth blocks of the pressing mechanism realize multi-point secondary pressing through the oblique windows, thereby avoiding the accumulation of movement errors of the segmented support and ensuring that the drill rod is stable and without offset during processing. The whole-root clamping design fundamentally improves the positioning accuracy when cutting the flat pin groove, and solves the processing error problem caused by segmented adjustment and support gap of the traditional fixture.

[0026] The lifting and clamping mechanism uses a hydraulic lifting cylinder to drive the clamping die up and down. Combined with the positioning and clamping of the trapezoidal lifting groove and trapezoidal lifting strip, the clamping die and the supporting die can be quickly connected and separated. During clamping, there is no need to adjust the support sections one by one. The hydraulic system can complete the lifting and lowering of the clamping die and the multi-point pressure of the pressing mechanism with one click, which significantly simplifies the operation process. At the same time, the base plate can be flexibly adjusted to the installation position by means of the quick locking structure of the lifting and locking block and the T-slot of the workbench, which greatly shortens the clamping time and meets the needs of efficient production.

[0027] The base plate of the clamping mechanism is equipped with a curved nozzle to achieve downward-slanted side-spray cooling, spraying coolant directly onto the cutting area, effectively reducing tool temperature and flushing waste chips, thereby increasing the service life of the end mill. The open design of the side milling window facilitates waste discharge, preventing debris accumulation from affecting machining accuracy, providing stable cooling and chip removal guarantees for high-speed cutting, and creating a good machining environment.

[0040] Wherein, the supporting clamp mechanism 3 includes a base plate 7, a lifting and locking block 8, a supporting clamping die 10 and a screw-in bolt 16. The plate body of the base plate 7 is installed at the T-slot of the workbench 2 through the lifting and locking block 8 and the flange nut 9, and the surface of the base plate 7 between the lifting and locking blocks 8 is welded with a supporting clamping die 10. A drill rod accommodating groove 11 is provided in the die body of the supporting clamping die 10, and a circular convex portion 13 and a block convex portion 14 are raised upward at the die heads at both ends of the supporting clamping die 10. A screw-in hole 15 that communicates with the drill rod accommodating groove 11 inside the supporting clamping die 10 is provided at the circular convex portion 13 and the block convex portion 14, and a screw-in bolt 16 for pressing the two ends of the drill rod is screwed into the screw-in hole 15.

At this time, the drill tail and the drill head of the drill rod are respectively against the circular convex part 13 and the block convex part 14, and then the screw-in bolt 16 is screwed into the screw bottom hole 13 of the circular convex part 13 and the block convex part 14, so as to symmetrically press the drill rod in the support clamp 10 for initial clamping and positioning, and ensure that the rod body of the drill rod used for processing the flat pin groove is at the side milling machine 12 of the support clamp 10.

When the base plate 7 slides on the surface of the workbench 2 to a position suitable for processing the drill rod, use a wrench to tighten the flange nut 9, so that the lifting and locking block 8 is lifted and clamped in the T-slot, thereby locking the base plate 7 to the surface of the workbench 2.

[0046] Among them, a clamping mechanism 4 is pressed on the top of the supporting mold 10 above the base plate 7, and the clamping mechanism 4 includes a clamping mold 19, a diagonal window 20 and a trapezoidal groove 21.

Then, the T-shaped block of the lifting and locking block 8 can be clamped into the T-shaped slot of the workbench 2 for clamping and sliding. When the base plate 7 slides on the surface of the workbench 2 to a position suitable for processing the drill rod, the flange nut 9 is tightened with a wrench so that the lifting and locking block 8 is lifted and clamped in the T-shaped slot, thereby locking the base plate 7 to the surface of the workbench 2.

[0058] Then the pressing mechanism 6 can be installed at the pressing die 19 of the pressing mechanism 4. After the vertical bending frame B32 of the pressing mechanism 6 is fastened and installed on the surface of the pressing die 19 near the diagonally opposite window 20 with bolts, the telescopic rod of the hydraulic cylinder 30 can be inserted into the notch groove of the notch support plate B31. Then the notch support plate B31 above the vertical bending frame B32 can be fastened to the cylinder body disc seat of the hydraulic cylinder 30 with the help of bolts. At this time, there is a pressing connecting plate B29 below the telescopic rod of the hydraulic cylinder 30, which can be fastened and connected with the bridge plate 28 with bolts, so that the hydraulic cylinder 30 can drive the bridge plate 28 to move up and down. Then the pressure tooth block 27 below the bridge plate 28 can enter the drill rod groove 11 of the pressing die 19 along the diagonally opposite window 20.

[0059] Then, the clamping mechanism 3 and the pressing mechanism 4 are assembled with the help of the lifting and clamping mechanism 5. The pressing plate A22 of the lifting and clamping mechanism 5 can be clamped in the trapezoidal lifting groove 21 of the pressing die 19 with the help of the trapezoidal lifting bar 23 for positioning and clamping. Then, the pressing plate A22 and the pressing die 19 are locked with bolts. Then, the telescopic rod of the hydraulic lifting cylinder 24 above the pressing plate A22 can be clamped into the notched supporting plate A25, and the outer disc seat of the hydraulic lifting cylinder 24 is locked with bolts. At this time, the vertical bending frame A26 outside the notched supporting plate A25 can be locked on the surface of the base plate 7 with the help of bolts to obtain support.

[0060] After the tube body of the bent nozzle 18 is inserted into the side mounting groove 17 of the base plate 7, the bent nozzle 18 is fixed and positioned in the column hole of the side mounting groove 17 with the bottom column. Then, the bottom tube body of the bent nozzle 18 can be screwed with some tube bodies with threaded fittings to connect to the liquid pump for extracting coolant to obtain coolant. The tube body connecting the bent nozzle 18 and the coolant pump can also be connected by assembling two sections of the tube body with a simple liquid valve, so as to facilitate the control of the coolant spraying amount at the bent nozzle 18.

[0061] When the drill rod needs to be cut into a flat pin groove, the hydraulic lifting cylinder 24 can be used to lift the clamping die 19, and then the drill rod is placed in the drill rod receiving groove 11 of the supporting clamping die 10. At this time, the screw holes 15 of the round convex portion 13 and the block convex portion 14 can be screwed into the screw bolts 16 to perform the initial pressure against the two ends of the drill rod. Then the hydraulic lifting cylinder 24 can obtain the clamping die 19 and lower it. The clamping die 19 uses its own drill rod receiving groove 11 to cooperate with the drill rod receiving groove 11 of the supporting clamping die 10 to press the drill rod as a whole. Then the hydraulic pressure cylinder 24 of the pressing mechanism 6 can drive the bridge plate 28 to descend, and the pressure tooth block 27 under the bridge plate 28 is guided to descend along the three groups of oblique windows 20 opened on the surface of the clamping die 19, thereby performing a multi-point secondary pressure against the entire clamped drill rod, so that the drill rod is stably clamped on the workbench 2 surface of the milling machine body 1, and then the coolant pump can draw coolant to the curved nozzle 18 so that the coolant can be The bent nozzle 18 sprays toward the side milling window 12 of the supporting die 10. At this time, an end mill can be installed at the tool holder of the milling machine body 1, and then the milling machine uses the end mill to perform flat pin groove cutting at the side milling windows 12 of the supporting die 10 and the pressing die 19, and the bent nozzle 18 can spray coolant to the drill rod in the cutting process at this time, thereby performing downward inclined side spray cooling, and the waste material after the drill rod is cut can fall outward from the side milling window 12. After the drill rod is stably clamped by the supporting die 10 and the pressing die 19, it is ensured that the drill rod is not prone to movement error during processing, and the accuracy of the drill rod during flat pin groove processing is ensured. When the drill rod processing is completed, the coolant at the bent nozzle 18 is closed, and the pressing die 19 is lifted by the hydraulic lifting cylinder 24, and then the screw bolt 16 is screwed out outward, and then the drill rod can be taken out from the supporting die 10 for subsequent processing, and the waste chips at the supporting die 10 can be manually blown out with an air gun, which is convenient for the next group.

[0062] In the present invention, in order to conveniently display the installation position of the lifting and clamping mechanism 5, one side plate of the base plate 7 on which the vertical bending frame A26 is installed is displayed at the workbench 2 away from the milling machine body 1. If it is to facilitate the loading and unloading operations of the drill rod, the one side plate of the base plate 7 on which the vertical bending frame A25 is installed can be selected to be installed on the surface of the workbench 2 close to the milling machine body 1, so as to reduce the influence of the vertical bending frame A26 on the loading and unloading positions during the processing of the drill rod. At the same time, the present invention only provides a side mounting groove 17 on the base plate 7 on one side of the support clamping die 10 to install the bent nozzle 18. If the drill rod needs to be processed on both sides, the side mounting grooves 17 can be selected to be provided on both sides of the support clamping die 10 to install the nozzle 18, and In the present invention, there is sufficient spacing between the two groups of vertical bending frames B32 installed on the surface of the clamping die 19 near its own side milling window 12 to prevent the hydraulic cylinder 30 above the bending frame B32 from affecting the processing space of the vertical milling cutter. The height of the hydraulic cylinder 30 and the vertical bending frame B32 can be lowered as needed, thereby further improving the processing space of the vertical milling cutter. At the same time, the vertical milling cutter can also choose a vertical milling cutter with a long tool rod to obtain sufficient processing space. The hydraulic lifting cylinder 24 and the hydraulic cylinder 30 in the present invention need to be connected to the existing external hydraulic system for on-demand control. The lifting and lowering of the clamping die 19 and the multi-point pressure of the pressing mechanism 6 can be completed by one click through the hydraulic system, which can significantly simplify the operation process.
