Description

Technical Field

[0001] The present invention relates to the technical field of drilling equipment, and in particular to a single-head automatic drilling equipment. Background Art

[0002] In the field of automatic drilling processing of steel bar collars, existing equipment has significant feeding and positioning defects: First, due to the arc-shaped surface and axial through-hole structural features of the collar pipe body, the traditional vibrating disk feeding mechanism is prone to cause stacking and jamming of the pipe bodies, and manual intervention is required for directional arrangement, resulting in insufficient automation rate; during drilling, the pipe body is prone to circumferential offset under the radial force, resulting in a relatively high out-of-tolerance rate of the hole diameter position; it cannot complete processing quickly.

[0003] In view of the above defects, the inventor actively conducts research and innovation in order to create a single-head automatic drilling equipment, making it more valuable in industrial use. Summary of the Invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide a single-head automatic drilling equipment.

[0005] A single-head automatic drilling equipment of the present invention includes a drilling machine frame. At the tail end of one side of the drilling machine frame, there is a feeding part for feeding. On the working table of the drilling machine frame, there is a clamping head that can move horizontally. At the rear side of the clamping head, there is an inclined feeding rack. The tail end of the feeding rack is docked with the feeding part. When the clamping head and the drilling part are on the same axis, it is the drilling station. The drilling part can move back and forth on the working table of the drilling machine frame. When the clamping head is on the same axis as the ejector cylinder, it is the feeding station.

[0006] This single-head automatic drilling equipment realizes the efficient processing of steel bar collars through modular design: The drilling machine frame serves as the main framework. The feeding part at its tail end and the inclined feeding rack form a continuous feeding channel. The horizontally movable clamping head has both positioning and transfer functions. When it is coaxial with the drill part that can be adjusted back and forth, it constitutes the drilling station. When it is coaxial with the ejector cylinder, it changes to the feeding station. This double-station layout enables the feeding and drilling processes to run in parallel. The inclined design of the feeding rack utilizes gravity to assist in discharging materials, and together with the horizontal movement of the clamping head, effectively solves the problems of jamming and positioning offset of the collar pipe body in traditional equipment.

[0007] Further, the feeding part includes a frame-shaped base. Inside the base, there is an inwardly inclined material plate. The bottom end of the material plate contacts the lifting plate. There are at least two groups of lifting plates. The bottom of the lifting plate is fixedly installed with a lifting frame. Between the upper cross plate of the lifting frame and the bottom plate of the base, a first cylinder is installed. The first cylinder can drive the lifting frame to move up and down along the guide rod. The two sides of the lifting frame are sleeved on the guide rod through sliding sleeves. Between the two lifting plates, there is a support plate fixed on the side vertical plate of the base.

[0008] The loading part adopts a stepped lifting structure to realize the automatic sorting and conveying of steel bar couplings: an inclined material plate is arranged inside the frame-type base to form a V-shaped storage channel, and multiple sets of lifting plates are linked with the first cylinder through the lifting frame to complete precise lifting and lowering movements under the constraint of the guide rod; the support plate is fixed to the vertical plate to form an intermediate limit platform. When the lifting plate descends, the coupling pipe body rolls to the support plate for temporary storage. When it rises, it pushes the upper pipe body to continue feeding, forming an intermittent lifting-retention circulation feeding mode, which effectively solves the problem of arc-shaped pipe bodies being stacked and stuck in traditional material channels.

[0009] Furthermore, a horizontal feed plate is installed at the top of the base, sprockets are installed at both ends of the feed plate, chains are mounted on the sprockets, one of the sprockets is driven by a driving motor installed at the end of the feed plate, a horizontal baffle is fixed to the upper end of the vertical plate on one side of the base, the baffle is located on the outside of the chain, a vertical baffle is fixed to one end of the feed plate, the gap between the baffles is used as a groove for material rolling down, the front end of the groove is an inclined discharge plate, the discharge plate is connected to the feed rack, a second cylinder is fixed to the other end of the discharge plate, and a push plate is fixed to the telescopic rod of the second cylinder.

[0010] The feeding plate drives the chain to circulate through the driving motor. The baffle plate on the vertical plate and the baffle plate form a directional groove to limit the movement trajectory of the coupling pipe body. The inclined design of the discharge plate ensures that the pipe body maintains axial alignment when sliding into the feeding rack; the second cylinder drives the push plate to reciprocate, which can not only assist the pipe body to break away from the chain and enter the groove, but also force the retained pipe body into the discharge plate, forming a dual protection mechanism of "mechanical conveying-pneumatic filling", which significantly improves the feeding reliability of special-shaped couplings.

[0011] Furthermore, a vertical stud is fixed on one side of the feeding plate, and the stripping plate is sleeved on the stud. Nuts are screwed into both sides of the stripping plate to fix the relative height of the stripping plate. The stripping plate is tilted above the chain, and below the stripping plate is a stripping rack fixed on one side of the vertical plate, and the end of the stripping rack extends above the material plate.

[0012] The installation height of the stripper plate can be precisely adjusted by cooperating with the stud and nut. Its inclination angle forms a dynamic interference area with the chain running plane. When the stacking height of the tubes exceeds the set value, the excess tubes slide along the stripper plate into the stripper rack. The rack is supported by the vertical plate and extends to the top of the material plate to form a closed-loop return channel. This height-adjustable mechanical interception method not only ensures the normal feeding process, but also automatically guides the excess tubes back to the storage area, solving the jamming problem caused by excessive stacking of materials in traditional equipment.

[0013] Furthermore, the clamping head is mounted on a movable seat, and the movable seat is slidably mounted on a slide seat on the drilling frame. The drilling frame is fixed with a third cylinder through the mounting seat, and the telescopic rod of the third cylinder is fixedly connected to the slide seat.

[0014] The clamping head and the sliding seat form a secondary sliding pair through the moving seat. The third cylinder, as the power source, directly drives the sliding seat to move linearly along the drilling machine frame, causing the clamping head to move back and forth between the drilling station and the feeding station.

[0015] Further, a feeding support is fixed on the rear side of the clamping head on the drilling machine frame. A pushing cylinder is fixed on the feeding support. There is a vertical tail baffle at the tail end of the feeding rack. The telescopic rod of the pushing cylinder is located inside the tail baffle. The feeding port at the tail end of the clamping head can be coaxial with the telescopic rod of the pushing cylinder.

[0016] The feeding support serves as the installation base of the pushing cylinder. Its telescopic rod penetrates the tail baffle of the feeding rack to form an axial positioning reference. When the feeding port of the clamping head is in a coaxial state with the telescopic rod of the cylinder, the cylinder pushes the pipe body to complete the seamless transition of "feeding rack - clamping head". The tail baffle not only restricts the axial movement of the pipe body on the feeding rack but also forms a mechanical interaction with the cylinder stroke to ensure that the pipe body is only pushed when the clamping head is in place. Further, a fourth cylinder and a slide rail are fixed on one side of the drilling part through a pushing support. The pushing plate is matched with the slide rail through a slider. One side of the pushing plate is a forward - extending pushing rod, and the pushing rod and the telescopic rod of the pushing cylinder are on the same axis.

[0017] The fourth cylinder integrated in the pushing support drives the pushing plate to move linearly through the slide rail. The pushing rod at its front end and the telescopic rod of the pushing cylinder form an axially symmetric reference. When feeding, the fifth cylinder pushes the pushing rod to be precisely guided along the slide rail so that the end of the pushing rod is in a docking position with the workpiece fed by the telescopic rod of the fourth cylinder, providing a position limit for feeding and preventing the fourth cylinder from pushing the workpiece out of the working area inside the clamping head.

[0018] Further, a material - blocking rack is fixed on one side of the feeding rack. The upper end of the material - blocking rack extends to the upper side of the feeding rack. A material - blocking cylinder is fixed at the upper end of the material - blocking rack. The material - blocking cylinder drives the material - separating plate to move up and down. The material - separating plate separates the raw materials located on the feeding rack.

[0019] The material - blocking rack serves as the main support structure. The material - blocking cylinder mounted on its upper extension drives the material - separating plate to move vertically up and down. When the raw materials on the feeding rack reach the preset station, the material - separating plate is driven by the cylinder to press down, and its cutting edge part is embedded into the gap between the raw materials to form a physical separation, which not only prevents the subsequent raw materials from continuing to move forward and causing stacking but also leaves an independent processing space for the front - end raw materials.

[0020] Further, there is a vertical limit seat at the tail end of the sliding seat. There is a concave clamping groove in the middle of the limit seat, and the clamping groove cooperates with the protrusion on the side of the clamping head.

[0021] Precise positioning of the sliding seat is achieved by using a concave-convex interlocking mechanical interlock design: The limit seat serves as a rigid reference part, and its V-shaped card slot forms an interference fit with the trapezoidal protrusion on the side of the clamping head. When the sliding seat moves to the end of the stroke, the inclined surfaces of the card slot and the protrusion come into contact to generate a radial component force, which not only eliminates the axial runout of the sliding seat but also realizes the function of precise positioning through the wedge structure.

[0022] Furthermore, there is a drilling base on the workbench of the drilling machine frame. The drilling base is equipped with a drilling seat through a slide rail-slider or other means. A drilling head is installed on the drilling seat, and an electric screw pair is installed on the drilling base. The screw of the electric screw pair cooperates with the nut sleeve installed at the bottom of the drilling seat. A drilling motor is fixed on the drilling seat through a mounting seat. A belt and belt pulleys are configured in the mounting seat, and the drilling motor drives the drilling head to rotate.

[0023] The drilling base supports the smooth movement of the drilling seat through a slide rail mechanism. The electric screw drive system converts rotational motion into precise linear feed. The drilling motor drives the drilling head to rotate through a belt transmission device. This separated structure not only ensures the high-speed running stability of the main shaft but also ensures the positioning accuracy of the feed system. The entire system is integrated on the machine tool workbench and can adapt to different specifications of drilling requirements.

[0024] With the above solutions, the present invention has at least the following advantages: 1. By horizontally moving the clamping head to switch between the drilling and loading stations, and cooperating with the drill part that can be adjusted back and forth, the processing and loading / unloading processes are carried out in parallel.

[0025] 2. The intermittent lifting system composed of an inclined material plate and multiple groups of lifting plates, cooperating with the support plate to form an alternating load-bearing structure, enables the coupling pipe body to achieve directional and layered feeding.

[0026] 3. The adjustable unloading plate and the unloading rack form a height-adaptive return material channel. When the material stacking in the chain conveying area exceeds the limit, the excess pipe bodies automatically slide back to the storage area.

[0027] 4. The V-shaped card slot of the limit seat forms an interference fit with the protrusion of the clamping head, eliminating the axial runout gap.

[0028] 5. The material distribution plate driven by the stop air cylinder can be accurately inserted into the gap between the pipe bodies to form a physical isolation belt. Cooperating with the synchronous action of the ejector air cylinder, the success rate of single-piece separation reaches 100%, completely solving the processing interference problem caused by pipe body stacking.

[0029] 6. Five groups of air cylinders and an electric screw pair constitute an intelligent drive system, and through sequential control, the whole process of lifting, conveying, clamping, drilling, and unloading is automated.

[0030] The above description is only an overview of the technical solution of the present invention.

Specific embodiments

[0034] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0035] See Figure 1 , this single-head automatic drilling equipment integrates the feeding part and the mobile clamping head 2 through the drilling machine frame 1 to realize double-station collaborative operation: when the clamping head moves horizontally to be coaxial with the drilling part 4, it enters the drilling station and completes precise processing through the drillable drilling part; when the clamping head moves to be coaxial with the ejector cylinder 5, it switches to the feeding station. At this time, the inclined feeding rack 3 conveys the materials in the feeding part to the clamping position. The modular layout realizes parallel operation of processing and feeding, significantly improving efficiency; the horizontally moving clamping head 2 and the adjustable drilling part form a flexible processing system; the pneumatic ejector and inclined feeding designs ensure accurate positioning of the materials and reduce the need for manual intervention.

[0036] See Figures 2-4 , this feeding part integrates the inclined material plate 7 and multiple groups of lifting plates 8 through the frame-shaped base 6, and the first cylinder 10 drives the lifting frame 9 to lift along the guide rod 11 to realize the stepped lifting of the materials. The support plate 12 forms an alternating bearing surface in the gap of the lifting plate 8 to ensure the stable upward movement of the materials layer by layer. The inclined material plate 7 and the alternating lifting mechanism effectively prevent the stacking and jamming of the materials; the combination of the guide rod 11 and the sliding sleeve ensures the accuracy of the lifting trajectory, and the support plate 12 provides redundant support, significantly improving the overall reliability.

[0037] See Figures 2-5, the feeding mechanism adopts a collaborative design of chain drive and pneumatic pusher. The driving motor 15 drives the sprocket chain 14 to horizontally convey materials to the position of the baffle 18. The baffle 17 restricts the lateral offset of the materials, enabling them to accurately fall into the directional groove formed by the baffle 18 and the baffle 17. During the process of the materials sliding into the feeding rack 3 through the inclined discharging plate 19, the second cylinder 20 implements end position calibration through the push plate 21. The combination of the chain 14 conveying and the baffle 17 ensures the continuous and stable transmission of high-density materials. The groove and the inclined discharging plate 19 form a gravity-assisted channel, reducing energy consumption. The pneumatic pusher module realizes millimeter-level positioning compensation, solving the problem of slip error. The overall structure combines the reliability of mechanical transmission and the flexibility of pneumatic control.

[0038] See Figure 5 , the discharging mechanism adjusts the vertical height of the discharging plate 23 through the stud 22 and the adjustable nut. The inclined discharging plate 23 can guide the stacked materials on the chain 14 to slide down to the discharging rack 24, and finally return to the material plate 7 to complete the cycle. The stud-nut structure enables quick adjustment without tools, adapting to different material thicknesses. The inclined discharging plate 24 uses gravity to automatically guide the materials to fall back, forming a closed-loop recovery path with the discharging rack. The overall module is seamlessly integrated with the feeding system, realizing the dynamic recovery and secondary feeding of the stacked materials without stopping the machine, significantly improving the system fault tolerance rate and material utilization rate.

[0039] See Figure 6 , the clamping and positioning mechanism drives the sliding seat 26 to drive the moving seat 25 to move linearly through the third cylinder 27, realizing the precise advancement and retreat of the clamping head 2. The third cylinder 27 provides a stable and controllable linear thrust, ensuring the smooth movement of the clamping head 2 without jitter. The double-layer sliding structure of the sliding seat 26 and the moving seat 25 enhances the radial rigidity, avoiding axial offset during drilling. The whole set of systems combines the dual characteristics of fast pneumatic response and accurate mechanical guidance, and is particularly suitable for high-frequency and high-precision drilling and positioning operations.

[0040] See Figure 8 , the automatic feeding system realizes precise feeding through the axial coordination of the ejector cylinder 5 and the clamping head 2: when the materials are conveyed to the tail baffle 30 for positioning through the feeding rack 3, the telescopic rod of the ejector cylinder 5 pushes the materials into the feeding port 31 of the clamping head along the coaxial direction. The nested design of the tail baffle and the cylinder ensures zero deviation in the end face positioning of the materials. The coaxial layout of the ejector cylinder 5 and the clamping head 2 eliminates the angular offset during the pushing process. The integrated structure of the feeding bracket 28 and the drilling machine frame enhances the system rigidity. See Figure 7, the ejector mechanism uses the fourth cylinder 33 to drive the ejector plate 35 to move linearly along the slide rail 34, and forms a two-way collaborative feeding limit system with the ejector rod 36 arranged coaxially and the ejector cylinder 5. The slide rail and slider structure ensures high straightness of the movement trajectory of the ejector rod 26 and avoids lateral deviation; the axial symmetric design of the fourth cylinder 33 and the ejector cylinder 5 realizes two-way positioning of the workpiece, effectively eliminates the clamping displacement caused by unilateral force, ensures the consistency of the clamped workpiece position, and the high straightness of the processed product.

[0041] See Figure 9 , the material distribution mechanism drives the material distribution plate 45 to move vertically up and down through the stop cylinder 44, realizes precise separation control of the raw materials on the feeding rack 3, and the cantilever design of the stop rack 43 realizes three-dimensional space occupancy without interfering with the feeding path; the material distribution plate 45 driven by the stop cylinder 44 has a response speed of milliseconds and can adapt to high-speed feeding rhythms; the clearance fit between the material distribution plate 45 and the feeding rack 3 not only ensures the reliability of separation but also avoids scratching the surface of the raw materials. This structure is especially suitable for the continuous processing scenario of bar materials. By programming the control of the material distribution timing, it can effectively solve the problem of workpiece interference during dense feeding and improve the rhythm stability of the automated production line.

[0042] See Figure 6 , through the precise fit between the concave card slot of the limit seat 42 and the side protrusion of the clamping head 2, mechanical hard limit at the end point of the movement of the slide seat 26 is realized. The embedded design of the card slot of the limit seat 42 and the protrusion of the clamping head 2 provides rigid constraints in the XYZ three directions, effectively suppressing machining vibration; the hard contact limit method is more reliable and durable than sensor detection. This structure is especially suitable for heavy cutting working conditions. Through physical limit protection, it not only prevents the slide seat from overshooting and damaging the guide rail but also maintains a constant relative position between the tool and the workpiece, significantly improving the repeat positioning accuracy of deep hole drilling.

[0043] See Figure 8 , the electric screw pair 40 is used to drive the drilling seat 37 to move precisely along the slide rail, and the belt drive mechanism transmits the power of the drilling motor 41 to the drill head 38. The closed-loop control of the electric screw pair 40 realizes the feed accuracy of micrometers, which is especially suitable for stepped hole machining; the slide rail-slider combination ensures the linearity and anti-torsion of the axial movement.

[0044] Adjust the drilling seat 37 to the preset coordinates through the slide rail and slider, and the limit seat 42 provides mechanical hard limit protection. Then start the drilling motor 41 to drive the pulley group, drive the drill bit 38 to rotate at a set speed. During the feeding stage, the electric screw pair 40 pushes the drilling seat 37 to feed uniformly along the slide rail, and at the same time, the drilling resistance is monitored in real time to dynamically adjust the parameters. Finally, the tool retraction and reset are completed. After the drill bit is lifted, the system automatically returns to the initial working position to prepare for the next cycle.

[0045] The working principle of the present invention is as follows: Place the workpiece cut into segments on the loading section. Use the first cylinder 10 of the loading section to drive the multiple inclined lifting plates 8 to cycle up and down, and cyclically lift the workpieces located in the material plate 7 upward. Finally, transfer them to the chain 14 on the feeding plate 13. The drive motor 15 drives the chain 14 to drive, and then continuously drives the workpieces to be transferred to one side of the feeding rack 3. When moving to the end of the feeding plate 13, the push plate 21 is cyclically pushed out by the second cylinder 20, so that the workpieces are pushed onto the feeding rack 3. Utilize the inclined slope of the feeding rack 3, and the workpieces roll to the bottom of the feeding rack 3. At this time, the material blocking cylinder 44 drives the material dividing plate 45 to be located at the lower end, which is used to block the workpieces on the feeding rack 3.

[0046] When the clamping head 2 is loaded, the third cylinder 27 drives the clamping head 2 to be transferred to the position of the loading station. At this time, the material blocking cylinder 44 drives the material dividing plate 45 to perform a lifting operation. When rising, the lowermost workpiece slides down and contacts the inner side of the tail baffle 30. When descending, the two lowermost workpieces are separated. The ejector cylinder 5 is started to eject the lowermost workpiece into the feeding port 31 at the tail end of the clamping head 2. At the same time, the fourth cylinder 33 drives the ejector rod 36 to move forward to the preset position. Since the ejector rod 36, the telescopic rod of the ejector cylinder 5, and the feeding port 31 penetrating through the clamping head 2 are on the same axis, the ejector cylinder 5 drives the workpiece to be inserted into the clamping head 2, and the end of the workpiece contacts the ejector rod 36, completing the loading operation of the clamping head 2.

[0047] Subsequently, the clamping head 2 is transferred to the drilling station. The drilling head 38 moves forward under the drive of the electric screw pair 40 and drills the workpiece in the clamping head 2. After drilling, the drilling head 38 resets, and the clamping head 2 is transferred to the loading station.

[0048] At this time, the ejector cylinder 5 pushes the next workpiece to be inserted into the clamping head 2, and the previous workpiece disengages from the clamping head 2 and is collected. Subsequently, the ejector rod 36 moves forward to the preset position to perform front-end limit on the next workpiece, completing the processes of workpiece loading, drilling, unloading, and loading. Repeat this process to achieve automated production.

[0049] Finally, several points should be noted: First, in the description of this application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, which can be mechanical connection or electrical connection, or the communication inside two components, and can be directly connected. "Up", "down", "left", "right", etc. are only used to represent relative position relationships. When the absolute position of the object being described changes, the relative position relationship may change; Second: In the drawings of the disclosed embodiments of the present invention, only the structures related to the disclosed embodiments are involved. Other structures can refer to the general design. Without conflict, the same embodiment and different embodiments of the present invention can be combined with each other; Finally, the above are only the preferred embodiments of the present invention and are not used to limit the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
