Abstract
Description
Technical Field
[0001] This utility model relates to the field of tie rod technology, and in particular to a tie rod drilling mechanism. Background Technology
[0002] In the machining industry, tie rods are important structural components, and their drilling accuracy and processing efficiency significantly impact product performance. Currently, traditional tie rod drilling equipment faces many problems that urgently need to be solved in practical applications.
[0003] In the clamping and flipping process, existing drilling equipment typically uses fixed clamps to position the tie rod, which is difficult to adapt to the clamping requirements of tie rods of different specifications and shapes. When drilling is required on different sides or at different angles of the tie rod, manual disassembly and re-clamping are often necessary. This is not only cumbersome, but repeated clamping can also introduce positioning errors, leading to reduced drilling accuracy. At the same time, traditional flipping mechanisms rely heavily on manual operation, resulting in low automation and making it difficult to meet the requirements of rapid and precise adjustment of tie rod angles in mass production.
[0004] In terms of drilling protection, traditional drilling equipment lacks effective anti-splash design. Metal shavings, coolant, and other splashes generated during drilling can easily scatter, not only polluting the working environment and increasing cleanup costs, but also potentially threatening the personal safety of operators. Furthermore, splashed debris may enter the equipment, affecting its normal operation and lifespan, and reducing its stability and reliability.
[0005] Therefore, we propose a tie rod drilling mechanism. Utility Model Content
[0006] The main objective of this invention is to provide a tie rod drilling mechanism to prevent problems such as insufficient drilling position accuracy and low processing efficiency caused by the inability of traditional fixing fixtures to accommodate tie rods of different specifications, multiple manual clamping leading to positioning errors, and low automation of the flipping mechanism. It also aims to avoid environmental pollution, operator safety threats, and equipment operational stability issues caused by drilling spatter during the drilling process. This improves the positioning accuracy and processing efficiency of tie rod drilling, reduces labor intensity, effectively blocks drilling spatter, improves the working environment, ensures operator safety, and extends equipment lifespan and operational reliability, thus effectively solving the problems in the background art.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] A tie rod drilling mechanism includes a worktable. A second moving mechanism is provided on the top of the worktable, which moves left and right. Two symmetrical first moving mechanisms are provided on the top of the worktable and inside the second moving mechanism, which also move left and right. Symmetrical flipping mechanisms are provided on the two first moving mechanisms. A clamping mechanism is provided at one end of each flipping mechanism. Each flipping mechanism includes a bracket. A first cylinder is fixedly mounted longitudinally on one side of the bracket. A rack is fixedly connected to the output end of the first cylinder. A limiting groove that slides with the rack is provided at the bottom end of the bracket. A rotating shaft passes through the bracket laterally and is rotatably connected to the bracket. A gear is fixedly connected to one end of the rotating shaft, and the gear meshes with the rack.
[0009] The clamping mechanism includes a second cylinder fixedly connected to the other end of the rotating shaft. The two output ends of the second cylinder are provided with symmetrical clamping arms. A V-shaped groove is provided on the inner side of the front part of the clamping arm, and an anti-slip pad is provided in the V-shaped groove.
[0010] The second moving mechanism is equipped with a lifting mechanism that drives the drilling mechanism to move up and down. The drilling mechanism includes a motor that is vertically fixedly installed at the bottom of the lifting mechanism. The output shaft of the motor is fixedly connected to a rotating column. A sliding cylinder that moves up and down is sleeved on the outside of the rotating column. A viewing window is provided on the outside of the sliding cylinder. Two symmetrical threaded rods are horizontally fixedly connected to the outside of the rotating column. Two sliding grooves that slide in cooperation with the corresponding threaded rods are vertically opened on the outside of the sliding cylinder. The end of the threaded rod away from the rotating column passes through the sliding groove and is externally threaded to a rotating sleeve. The rotating sleeve abuts against the outer wall of the sliding cylinder.
[0011] By adopting the above technical solution, the two relatively symmetrical first moving mechanisms can move left and right on the top of the worktable, and can adjust their own position according to the length and position of the pull rod to get closer to the pull rod;
[0012] When the first cylinder starts, its output end drives the rack to slide in the limiting groove. Since the gear meshes with the rack, the movement of the rack will drive the gear to rotate, which in turn causes the rotating shaft fixedly connected to the gear to rotate as well.
[0013] The second cylinder is fixed at the other end of the rotating shaft. The two output ends of the second cylinder drive the symmetrical clamping arms to move closer or further apart. When it is necessary to clamp the pull rod, the clamping arms move closer together and use the V-shaped groove on the inner front side to fit the pull rod. At the same time, the anti-slip pad can increase the friction and prevent the pull rod from slipping. If the angle of the pull rod needs to be changed, the rotating shaft is controlled by the first cylinder to rotate, which drives the clamped pull rod to flip.
[0014] The second moving mechanism can move left and right on the top of the worktable, and the lateral position of the drilling mechanism can be adjusted according to the drilling position requirements.
[0015] The lifting mechanism is mounted on the second moving mechanism and can drive the drilling mechanism to move up and down, thereby adjusting the height of the drilling mechanism and aligning the drill bit with the drilling position of the pull rod.
[0016] When the motor starts, its output shaft drives the rotating column to rotate, which in turn drives the drill bit mounted on the rotating column to rotate, starting the drilling operation on the pull rod. The threaded rod on the outside of the rotating column can slide up and down in the groove of the slide cylinder. By rotating the rotating sleeve, the position of the rotating sleeve on the threaded rod is changed. Since the rotating sleeve abuts against the outer wall of the slide cylinder, it can restrict the vertical position of the slide cylinder relative to the rotating column. The bottom of the slide cylinder is in contact with or close to the surface of the pull rod. When the drill bit is drilling, a closed space is formed around the drill bit. In this way, the debris, coolant and other splashes generated during the drilling process are blocked by the inner wall of the slide cylinder and cannot splash directly to the surroundings. The movement direction of the splashes is changed, so that they can only fall down inside the slide cylinder or along the inner wall of the slide cylinder. The operator can observe the drilling situation inside through the viewing window and make timely adjustments.
[0017] Furthermore, a circular through groove is provided at the bottom of the slide cylinder for the rotating column to pass through, and a drill bit is fixedly installed at the bottom end of the rotating column.
[0018] By adopting the above technical solution, the motor outputs power after starting, driving the rotating column to rotate. Since the drill bit is fixedly installed at the bottom of the rotating column, the drill bit will rotate synchronously with the rotating column. The rotating drill bit is the key to drilling operations. The cutting force generated by its high-speed rotation can drill the tie rod. The slide sleeve is fitted outside the rotating column, and the rotating column passes through the circular through groove at the bottom of the slide sleeve. This structure allows the slide sleeve to move up and down along the rotating column within a certain range.
[0019] Furthermore, the first moving mechanism includes a first slide rail fixedly connected to the top of the workbench and symmetrically arranged in pairs. A slide block is slidably connected to the first slide rail, and the top of the slide block is fixedly connected to the bottom of the bracket. A third cylinder is fixedly installed on the top of the workbench, and the output end of the third cylinder is fixedly connected to one side of the slide block.
[0020] By adopting the above technical solution, the third cylinder is fixedly installed on the top of the worktable. It is the power source of the first moving mechanism. When compressed air is introduced into the third cylinder, the piston inside the cylinder will generate linear motion under the action of air pressure, thereby causing the output end of the third cylinder to extend and retract. The output end of the third cylinder is fixedly connected to one side of the slide. Therefore, when the output end of the third cylinder extends or retracts, it will directly drive the slide to slide left and right on the first slide rail. The first slide rail is fixedly connected to the top of the worktable and is symmetrical in pairs, providing a sliding track and support for the slide, ensuring that the slide can move smoothly and accurately. Since the top of the slide is fixedly connected to the bottom of the bracket, and the bracket is part of the flipping mechanism, which is equipped with a clamping mechanism, the left and right movement of the slide will drive the flipping mechanism and the clamping mechanism to move together. By controlling the extension and retraction of the third cylinder, the position of the clamping mechanism can be precisely adjusted so that it can accurately approach or move away from the pull rod to be processed, so as to realize the clamping operation of pull rods of different lengths and positions.
[0021] Furthermore, the second moving mechanism includes two second slide rails fixedly connected to the top of the worktable and symmetrical to each other, and a gantry frame is slidably connected to the second slide rails by a drive device.
[0022] By adopting the above technical solution, two symmetrical second slide rails are fixedly connected to the top of the worktable, providing tracks and support for the movement of the gantry. The second slide rails have a high-precision guiding function, ensuring the straightness and stability of the gantry during movement, reducing swaying and deviation, and ensuring the accuracy of the drilling position. The drive device is the power source for the gantry to slide on the second slide rails. Common drive devices can be a combination of a motor and a lead screw and nut pair, a linear motor, or a cylinder, etc. Taking the motor and lead screw and nut pair as an example, after the motor starts, it drives the lead screw to rotate, and the screw on the lead screw... The nut is fixedly connected to the gantry frame, and the rotational motion of the lead screw is converted into the linear motion of the nut and the gantry frame, thereby enabling the gantry frame to slide left and right on the second slide rail. In actual drilling operations, according to the different drilling position requirements on the tie rod, the operation of the drive device is controlled to move the gantry frame left and right on the second slide rail to the appropriate position. Since the lifting mechanism is set on the gantry frame and the drilling mechanism is installed on the lifting mechanism, the movement of the gantry frame will synchronously drive the drilling mechanism to move, so that it is accurately aligned with the position on the tie rod that needs to be drilled, thus preparing for subsequent drilling operations.
[0023] Furthermore, the lifting mechanism includes a fourth cylinder fixedly installed on the top of the gantry frame. The output end of the fourth cylinder passes through the gantry frame and is fixedly connected to a movable plate, and the bottom of the movable plate is connected to the top of the motor.
[0024] By adopting the above technical solution, the fourth cylinder is fixedly installed on the top of the gantry frame. It serves as the power source for the lifting mechanism, driving the internal piston through compressed air. When compressed air is introduced into the inlet of the fourth cylinder, the internal air pressure changes, pushing the piston and its connected output end to produce linear motion. The output end of the fourth cylinder can extend and retract, depending on the direction of gas flow and the air pressure. After passing through the gantry frame, the output end of the fourth cylinder is fixedly connected to the moving plate. Therefore, when the output end of the fourth cylinder extends or retracts, it directly drives the moving plate to move up and down. It plays a role in force transmission and connection, transmitting the power generated by the fourth cylinder to the motor of the drilling mechanism. Since the bottom of the moving plate is connected to the top of the motor, and the motor is an important part of the drilling mechanism, the up and down movement of the moving plate will drive the entire drilling mechanism to rise and fall. When drilling is required on the tie rod, the output end of the fourth cylinder extends, pushing the moving plate and the drilling mechanism downward, so that the drill bit approaches and contacts the tie rod, and the drilling operation begins. After drilling is completed, the output end of the fourth cylinder retracts, driving the moving plate and the drilling mechanism upward, so that the drill bit leaves the tie rod, preparing for the next operation or workpiece replacement.
[0025] Furthermore, two symmetrical sliding rods are vertically fixedly connected to the top of the movable plate. The top of the sliding rods passes through the through holes on the gantry frame, and the sliding rods are slidably connected to the gantry frame.
[0026] By adopting the above technical solution, two symmetrical sliding rods are vertically fixed to the top of the moving plate, and the top of the sliding rods passes through the through hole on the gantry and is slidably connected with the gantry. The through hole on the gantry provides a guide channel for the sliding rods, so that the sliding rods can only slide in the vertical direction. When the fourth cylinder drives the moving plate to move up and down, the sliding rods slide synchronously in the through hole of the gantry, thereby ensuring that the moving plate can only move in the vertical direction, avoiding left and right swaying or deviation during the lifting process, providing precise guidance for the movement of the moving plate, and thus ensuring that the drilling mechanism can accurately reach the predetermined position when lifting.
[0027] The sliding connection between the slide bar and the gantry increases the support points for the moving plate during lifting. The two symmetrical slide bars can evenly bear the weight of the moving plate and the drilling mechanism in the vertical direction, as well as various forces generated during movement, making the entire system more stable during lifting. During drilling operations, the drilling mechanism may be subjected to external forces such as the cutting force between the drill bit and the tie rod. The slide bars can effectively resist the influence of these external forces on the moving plate, preventing the moving plate from tilting or shaking, thereby ensuring the accuracy and quality of drilling.
[0028] Compared with the prior art, the present invention has the following beneficial effects:
[0029] This utility model discloses a tie rod drilling mechanism. The flipping mechanism in the patent achieves precise flipping and positioning of the tie rod through the linkage design of a first cylinder, rack, gear, and rotating shaft. The first cylinder drives the rack to slide within the limiting groove. The meshing transmission between the gear and rack drives the rotating shaft to rotate, thereby enabling the clamping mechanism fixed on the rotating shaft to achieve precise flipping. This design allows for quick and accurate adjustment of the tie rod angle to meet the processing requirements of different drilling positions and angles. Simultaneously, two symmetrical first moving mechanisms can be flexibly adjusted according to the tie rod length and position. Combined with the flipping mechanism, this achieves adaptive clamping and positioning of tie rods of different specifications, eliminating the need for multiple manual clamping and adjustments, effectively improving processing efficiency and drilling position accuracy, and reducing labor intensity.
[0030] This utility model discloses a tie-rod drilling mechanism. The innovative design of the sliding cylinder in the drilling mechanism effectively solves the problem of splashing during drilling. The sliding cylinder is sleeved outside the rotating column, with its bottom contacting or approaching the surface of the tie rod. During drilling, it forms a closed space, blocking debris, coolant, and other splashes generated during drilling within the sliding cylinder. The inner wall of the sliding cylinder alters the direction of the splashes, ensuring they only fall inside the cylinder or down the inner wall, preventing splashes from affecting operators and the working environment. Furthermore, a viewing window on the outside of the sliding cylinder allows operators to observe the drilling process in real time, ensuring smooth drilling operations. This design not only improves operational safety and reduces cleaning workload but also effectively protects the equipment, extends its service life, and enhances its operational stability and reliability.

[0036] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0037] To prevent problems such as insufficient drilling accuracy and low processing efficiency caused by traditional fixed clamps being unable to accommodate different specifications of tie rods, repeated manual clamping leading to positioning errors, and low automation of the flipping mechanism, as well as to avoid environmental pollution, operator safety threats, and equipment operational stability issues caused by drilling spatter during drilling, this method aims to improve the positioning accuracy and processing efficiency of tie rod drilling, reduce labor intensity, effectively block drilling spatter, improve the working environment, ensure operator safety, and extend equipment lifespan and operational reliability. Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a tie rod drilling mechanism includes a worktable 1. A second moving mechanism 26 is provided on the top of the worktable 1, which moves left and right. Two symmetrical first moving mechanisms 2 are provided on the top of the worktable 1 and inside the second moving mechanism 26, which also move left and right. Symmetrical flipping mechanisms are provided on the two first moving mechanisms 2. A clamping mechanism is provided at the opposite end of each flipping mechanism. Each flipping mechanism includes a bracket 3. A first cylinder 4 is fixedly mounted longitudinally on one side of the bracket 3. A rack 5 is fixedly connected to the output end of the first cylinder 4. A limiting groove 6 is provided at the bottom end of the bracket 3, which slides with the rack 5. A rotating shaft 7 passes through the bracket 3 laterally and is rotatably connected to the bracket 3. A gear 8 is fixedly connected to one end of the rotating shaft 7, and the gear 8 meshes with the rack 5.
[0038] The clamping mechanism includes a second cylinder 9 fixedly connected to the other end of the rotating shaft 7. The two output ends of the second cylinder 9 are provided with symmetrical clamping arms 10. A V-groove 11 is provided on the inner side of the front part of the clamping arm 10, and an anti-slip pad 12 is provided in the V-groove 11.
[0039] The second moving mechanism 26 is provided with a lifting mechanism 13 that drives the drilling mechanism to move up and down. The drilling mechanism includes a motor 14 that is vertically fixedly installed at the bottom of the lifting mechanism 13. The output shaft of the motor 14 is fixedly connected to a rotating column 15. A sliding cylinder 16 that moves up and down is sleeved on the outside of the rotating column 15. A viewing window 17 is provided on the outside of the sliding cylinder 16. Two symmetrical threaded rods 18 are horizontally fixedly connected to the outside of the rotating column 15. Two sliding grooves 19 are vertically opened on the outside of the sliding cylinder 16 that slide in cooperation with the corresponding threaded rods 18. The end of the threaded rod 18 away from the rotating column 15 passes through the sliding groove 19 and is externally threadedly connected to a rotating sleeve 20. The rotating sleeve 20 abuts against the outer wall of the sliding cylinder 16.
[0040] In use, the two symmetrical first moving mechanisms 2 can move left and right on the top of the worktable 1, and can adjust their own position according to the length and position of the pull rod to get closer to the pull rod;
[0041] The first cylinder 4 starts, and its output end drives the rack 5 to slide in the limiting groove 6. Since the gear 8 meshes with the rack 5, the movement of the rack 5 will drive the gear 8 to rotate, which in turn causes the rotating shaft 7, which is fixedly connected to the gear 8, to rotate as well.
[0042] The second cylinder 9 is fixed at the other end of the rotating shaft 7. The two output ends of the second cylinder 9 drive the symmetrical clamping arms 10 to move closer or further apart. When it is necessary to clamp the pull rod, the clamping arms 10 move closer together and use the V-groove 11 on the inner side of their front to fit the pull rod. At the same time, the anti-slip pad 12 can increase the friction and prevent the pull rod from slipping. If the angle of the pull rod needs to be changed, the rotating shaft 7 is controlled to rotate by the first cylinder 4, which drives the clamped pull rod to flip.
[0043] The second moving mechanism 26 can move left and right on the top of the worktable 1, and the lateral position of the drilling mechanism can be adjusted according to the drilling position requirements.
[0044] The lifting mechanism 13 is mounted on the second moving mechanism 26 and can drive the drilling mechanism to move up and down, thereby adjusting the height of the drilling mechanism and aligning the drill bit with the drilling position of the pull rod.
[0045] When motor 14 starts, its output shaft drives the rotating column 15 to rotate, which in turn drives the drill bit mounted on the rotating column 15 to rotate, starting the drilling operation on the pull rod. The threaded rod 18 on the outside of the rotating column 15 can slide up and down in the groove 19 of the slide cylinder 16. By rotating the rotating sleeve 20, the position of the rotating sleeve 20 on the threaded rod 18 is changed. Since the rotating sleeve 20 abuts against the outer wall of the slide cylinder 16, the vertical position of the slide cylinder 16 relative to the rotating column 15 is restricted. The bottom of the slide cylinder 16 is in contact with or close to the surface of the pull rod. When the drill bit 22 is drilling, a closed space is formed around the drill bit. In this way, the debris, coolant and other splashes generated during the drilling process are blocked by the inner wall of the slide cylinder and cannot splash directly to the surroundings. The direction of movement of the splashes is changed, so that they can only fall down inside the slide cylinder or along the inner wall of the slide cylinder. The operator can observe the drilling situation inside through the viewing window 17 and make timely adjustments.
[0046] For example, such as Figure 4 As shown, the present invention also includes a circular through groove 21 at the bottom of the slide cylinder 16 for the rotating column 15 to pass through, and a drill bit 22 is fixedly installed at the bottom end of the rotating column 15.
[0047] When in use, the motor 14 starts and outputs power to drive the rotating column 15 to rotate. Since the drill bit 22 is fixedly installed at the bottom of the rotating column 15, the drill bit 22 will rotate synchronously with the rotating column 15. The rotating drill bit 22 is the key to drilling operations. The cutting force generated by its high-speed rotation can drill the tie rod. The slide cylinder 16 is sleeved on the outside of the rotating column 15, and the rotating column 15 passes through the circular through groove 21 at the bottom of the slide cylinder 16. This structure allows the slide cylinder 16 to move up and down along the rotating column 15 within a certain range.
[0048] For example, such as Figure 1 As shown, the present invention also includes the following: the first moving mechanism 2 includes a first slide rail 23 fixedly connected to the top of the workbench 1 and symmetrically arranged in pairs; a slide block 24 is slidably connected to the first slide rail 23; the top of the slide block 24 is fixedly connected to the bottom of the bracket 3; a third cylinder 25 is fixedly installed on the top of the workbench 1; and the output end of the third cylinder 25 is fixedly connected to one side of the slide block 24.
[0049] In use, the third cylinder 25 is fixedly installed on the top of the worktable 1. It is the power source of the first moving mechanism 2. When compressed air is introduced into the third cylinder 25, the piston inside the cylinder will move linearly under the action of air pressure, thereby causing the output end of the third cylinder 25 to extend or retract. The output end of the third cylinder 25 is fixedly connected to one side of the slide 24. Therefore, when the output end of the third cylinder 25 extends or retracts, it will directly drive the slide 24 to slide left and right on the first slide rail 23. The first slide rail 23 is fixedly connected to the top of the worktable 1 and is connected in pairs. Symmetry provides a sliding track and support for the slide block 24, ensuring that the slide block 24 can move smoothly and accurately. Since the top of the slide block 24 is fixedly connected to the bottom of the bracket 3, and the bracket 3 is part of the flipping mechanism, which is equipped with a clamping mechanism, the left and right movement of the slide block 24 will drive the flipping mechanism and the clamping mechanism to move together. By controlling the extension and retraction of the third cylinder 25, the position of the clamping mechanism can be precisely adjusted so that it can accurately approach or move away from the pull rod to be processed, so as to realize the clamping operation of pull rods of different lengths and positions.
[0050] For example, such as Figure 1 As shown, the present invention also includes the second moving mechanism 26, which includes two second slide rails 27 fixedly connected to the top of the workbench 1 and symmetrical to each other, and a gantry frame 28 is slidably connected to the second slide rails 27 by a driving device.
[0051] In use, two symmetrical second slide rails 27 are fixedly connected to the top of the worktable 1, providing a track and support for the movement of the gantry 28. The second slide rails 27 have a high-precision guiding function, ensuring the straightness and stability of the gantry 28 during movement, reducing swaying and deviation, and ensuring the accuracy of the drilling position. The drive device is the power source for the gantry 28 to slide on the second slide rails 27. Common drive devices can be a combination of a motor and a lead screw and nut pair, a linear motor, or a cylinder, etc. Taking the motor and lead screw and nut pair as an example, after the motor starts, it drives the lead screw to rotate, and the nut on the lead screw and the gantry 28 slide ... With the fixed connection 8, the rotational motion of the lead screw is converted into the linear motion of the nut and the gantry 28, thereby enabling the gantry 28 to slide left and right on the second slide rail 27. In actual drilling operations, according to the different drilling position requirements on the tie rod, the operation of the drive device is controlled to move the gantry 28 left and right on the second slide rail 27 to the appropriate position. Since the lifting mechanism 13 is set on the gantry 28 and the drilling mechanism is installed on the lifting mechanism 13, the movement of the gantry 28 will synchronously drive the drilling mechanism to move, so that it is accurately aligned with the position on the tie rod that needs to be drilled, thus preparing for subsequent drilling operations.
[0052] For example, such as Figure 1As shown, the present invention also includes a fourth cylinder 29 fixedly installed on the top of the gantry frame 28. The output end of the fourth cylinder 29 passes through the gantry frame 28 and is fixedly connected to a movable plate 30. The bottom of the movable plate 30 is connected to the top of the motor 14.
[0053] In use, the fourth cylinder 29 is fixedly installed on the top of the gantry 28. It serves as the power source for the lifting mechanism 13, driving the internal piston through compressed air. When compressed air is introduced into the inlet of the fourth cylinder 29, the internal air pressure changes, pushing the piston and its connected output end to produce linear motion. The output end of the fourth cylinder 29 can extend and retract, depending on the direction of air flow and the air pressure. After passing through the gantry 28, the output end of the fourth cylinder 29 is fixedly connected to the moving plate 30. Therefore, when the output end of the fourth cylinder 29 extends or retracts, it directly drives the moving plate 30 to move up and down. The moving plate 30 acts as a force... The fourth cylinder 29 transmits power to the motor 14 of the drilling mechanism through its transmission and connection function. Since the bottom of the moving plate 30 is connected to the top of the motor 14, and the motor 14 is an important component of the drilling mechanism, the up and down movement of the moving plate 30 will drive the entire drilling mechanism to rise and fall. When drilling is required on the tie rod, the output end of the fourth cylinder 29 extends, pushing the moving plate 30 and the drilling mechanism downward, so that the drill bit 22 approaches and contacts the tie rod, and the drilling operation begins. After drilling is completed, the output end of the fourth cylinder 29 retracts, driving the moving plate 30 and the drilling mechanism upward, so that the drill bit 22 leaves the tie rod, preparing for the next operation or workpiece replacement.
[0054] For example, such as Figure 1 , Figure 3 As shown, the present invention also includes two symmetrical sliding rods 31 vertically fixedly connected to the top of the movable plate 30. The top of the sliding rods 31 passes through the through hole on the gantry frame 28, and the sliding rods 31 are slidably connected to the gantry frame 28.
[0055] In use, two symmetrical sliding rods 31 are vertically fixed to the top of the moving plate 30, and the top of the sliding rods 31 passes through the through hole on the gantry 28 and is slidably connected with the gantry 28. The through hole on the gantry 28 provides a guide channel for the sliding rods 31, so that the sliding rods 31 can only slide in the vertical direction. When the fourth cylinder 29 drives the moving plate 30 to move up and down, the sliding rods 31 slide synchronously in the through hole of the gantry 28, thereby ensuring that the moving plate 30 can only move in the vertical direction, avoiding left and right swaying or deviation during the lifting process, providing precise guidance for the movement of the moving plate 30, and thus ensuring that the drilling mechanism can accurately reach the predetermined position when lifting.
[0056] The sliding connection between the slide bar 31 and the gantry 28 increases the support points for the moving plate 30 during the lifting process. The two symmetrical slide bars 31 can evenly bear the weight of the moving plate 30 and the drilling mechanism in the vertical direction, as well as various forces generated during the movement, making the whole system more stable during the lifting process. During the drilling operation, the drilling mechanism may be subjected to external forces such as the cutting force between the drill bit and the tie rod. The slide bar 31 can effectively resist the influence of these external forces on the moving plate 30, prevent the moving plate 30 from tilting or shaking, and thus ensure the accuracy and quality of drilling.
[0057] It should be noted that this utility model is a pull rod drilling mechanism. Two relatively symmetrical first moving mechanisms 2, based on the length and position of the pull rod, drive the slide block 24 to slide left and right on the first slide rail 23 through the third cylinder 25, thereby driving the flipping mechanism and the clamping mechanism to approach the pull rod.
[0058] The first cylinder 4 is activated, and the output end drives the rack 5 to slide in the limiting groove 6, causing the gear 8 meshing with it to rotate, which in turn drives the rotating shaft 7 to rotate. The second cylinder 9 drives the symmetrical clamping arms 10 to move closer to each other, and uses the V-groove 11 and anti-slip pad 12 to clamp the pull rod. If it is necessary to adjust the angle of the pull rod, the first cylinder 4 is activated again, and the pull rod is flipped by rotating the rotating shaft 7.
[0059] According to the drilling position requirements, the second moving mechanism 26 uses a drive device such as a motor and a lead screw and nut pair to make the gantry frame 28 slide left and right on the second slide rail 27, which drives the lifting mechanism 13 and the drilling mechanism installed on the gantry frame 28 to move laterally, so that the drilling mechanism is aligned with the drilling position on the pull rod.
[0060] When the fourth cylinder 29 in the lifting mechanism 13 is activated, its output end extends or retracts, driving the moving plate 30 to move up and down. The moving plate 30 is connected to the gantry frame 28 through the sliding cooperation of the slide rod 31 to ensure stable vertical movement, thereby driving the drilling mechanism to move up and down, so that the drill bit is aligned with the drilling height position on the pull rod.
[0061] When the motor 14 starts, the output shaft drives the rotating column 15 and the drill bit to rotate and begin drilling. By rotating the rotating sleeve 20, its position on the threaded rod 18 is changed, limiting the vertical position of the slide cylinder 16 relative to the rotating column 15, so as to adjust the drilling depth. The slide cylinder 16 forms a closed space around the drill bit during drilling, blocking debris and coolant splashes. The operator can observe the drilling situation through the viewing window 17 and make timely adjustments.
[0062] After drilling is completed, the output end of the fourth cylinder 29 retracts, driving the moving plate 30 and the drilling mechanism to move upward, causing the drill bit to leave the pull rod.
[0063] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
