Description

Technical Field

[0001] This invention relates to the field of bolt processing technology, and more specifically to a precision high-speed drilling machine for throttling bolts. Background Technology

[0002] During the manufacturing process of throttling bolts, it is usually necessary to open longitudinal through holes in their axial direction and transverse through holes in their sidewalls to meet the functional requirements of throttling flow control.

[0003] Traditional machining methods often employ manual clamping and step-by-step drilling. This involves first machining a hole in one direction using a conventional drilling machine or manual fixture, then re-clamping the workpiece and adjusting the angle to machine a hole in the other direction. This machining mode is not only cumbersome and labor-intensive, but the repeated clamping can easily introduce positioning errors, making it difficult to guarantee the positional accuracy and coaxiality of the holes. This is especially true for small-diameter, high L / D ratio throttling bolts, whose slender structures are prone to bending, deformation, or skew during clamping and drilling, further reducing the machining yield. Furthermore, while existing automated drilling equipment can achieve automatic feed in one direction, most lack automatic workpiece orientation conversion capabilities, still requiring manual intervention or additional flipping fixtures. This prevents the continuous machining of longitudinal and transverse holes in a single clamping, resulting in low production efficiency and difficulty in meeting the demands of high-volume precision machining. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a precision high-speed drilling machine for throttling bolts, so as to solve the problems existing in the background art.

[0005] The present invention provides the following technical solution: a precision high-speed drilling machine for processing throttling bolts, comprising a base, a bearing mechanism and a triggering mechanism being provided on the top of the base, and a drilling mechanism being provided on one side of the base. The bearing mechanism is used to clamp the throttling bolt and drive the throttling bolt to rotate between a vertical arrangement state and a horizontal arrangement state. The drilling mechanism is used to drill holes in the throttling bolt clamped on the bearing mechanism and trigger the triggering mechanism. The triggering mechanism is used to drive the bearing mechanism to rotate under the triggering action of the drilling mechanism.

[0006] Preferably, the bearing mechanism includes a bearing frame, a sliding plate, a first cylinder and a rotating shaft, with an electric slide rail provided on the bearing frame and the sliding plate slidably mounted on the electric slide rail.

[0007] Preferably, the sliding plate has an extension groove, and the extension groove has a through-hole. The first cylinder is fixedly installed on the support frame, and the output end of the first cylinder is fixedly connected to a positioning block.

[0008] Preferably, one end of the rotating shaft is fixedly connected to the support frame, a support frame is fixedly installed on the top of the base, the rotating shaft is rotatably installed on the support frame, and the axis of the rotating shaft is arranged horizontally.

[0009] Preferably, the perforation mechanism includes a lifting platform and a movable plate. The lifting platform is used to pull the movable plate to move in the vertical direction, and a fixed frame and a mounting frame are fixedly connected to one side of the movable plate.

[0010] Preferably, a drilling device is fixedly installed on the mounting frame, a second cylinder is fixedly installed on the top of the mounting frame, and a translation block is fixedly connected to the output end of the second cylinder.

[0011] Preferably, a guide rod is fixedly connected to the top of the fixed frame, the axis of the guide rod is arranged horizontally, a translation block is sleeved on the surface of the guide rod, and a roller is rotatably installed on one side of the translation block.

[0012] Preferably, the triggering mechanism includes a guide rod, a displacement block, and a connecting frame. The guide rod is fixedly installed on the top of the base, and the axis of the guide rod is arranged horizontally. The displacement block is sleeved on the surface of the guide rod, and a compression spring is sleeved on the surface of the guide rod.

[0013] Preferably, a first connecting rod and a second connecting rod are provided between the displacement block and the rotating shaft. One end of the first connecting rod is hinged to the top of the displacement block, the other end of the first connecting rod is hinged to one end of the second connecting rod, and the other end of the second connecting rod is fixedly connected to the rotating shaft.

[0014] Preferably, the connecting frame is fixedly connected to one side of the shifting block, and the connecting frame is provided with a first limiting plane, a triggering inclined plane and a second limiting plane, with the second limiting plane communicating with the triggering inclined plane.

[0015] The beneficial effects of this invention are: In this invention, the coordinated operation of the bearing mechanism, the drilling mechanism, and the triggering mechanism achieves fully automated operation of the throttling bolt, from automatic feeding, clamping and positioning, longitudinal drilling, automatic flipping to a horizontal state, and then transverse drilling. This improves processing efficiency and automation while ensuring drilling position accuracy. Specifically, in the bearing mechanism, the sliding plate, in conjunction with the first cylinder and the positioning block, uses the extension groove and the through-hole to quickly limit and clamp the bolt, avoiding deviations caused by manual clamping. In the drilling mechanism, the lifting platform drives the drilling equipment to move vertically. Combined with the translation block and rollers driven by the second cylinder, it can selectively cooperate with the first limiting plane, the triggering inclined plane, or the second limiting plane of the connecting frame in the triggering mechanism according to different processing stages. During the drilling process, the limiting plane ensures the stable locking of the bearing frame, thereby ensuring that the workpiece posture is fixed and vibration-free during longitudinal hole processing. When a direction change is needed, the roller rolls along the trigger ramp and pushes the displacement block to compress the spring. This, via the first and second connecting rods, precisely drives the rotating shaft to rotate 90 degrees, causing the support frame to smoothly flip the workpiece from vertical to horizontal. After flipping, the second limiting plane maintains this posture, allowing the drilling equipment to precisely drill in from the side, completing the opening of the transverse hole. Throughout the process, the workpiece only needs to be clamped once, eliminating the need for manual secondary adjustments. This avoids the cumulative errors caused by multiple positioning attempts and significantly reduces auxiliary time, making it suitable for high-precision multi-directional drilling of slender throttling bolts. Furthermore, the compression spring automatically resets after the transverse hole is machined, driving the support frame back to its initial state, facilitating unloading and loading for the next cycle, forming a continuous and efficient production cycle. This demonstrates excellent industrial practicality and promotional value. Attached Figure Description

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1 to 4 This invention provides a precision high-speed drilling machine for processing throttling bolts, including a base 1. The top of the base 1 is provided with a bearing mechanism 2 and a triggering mechanism 4. A drilling mechanism 3 is provided on one side of the base 1. The bearing mechanism 2 is used to clamp the throttling bolt and drive the throttling bolt to rotate between a vertical arrangement state and a horizontal arrangement state. The drilling mechanism 3 is used to drill holes in the throttling bolt clamped on the bearing mechanism 2 and trigger the triggering mechanism 4. The triggering mechanism 4 is used to drive the bearing mechanism 2 to rotate under the triggering action of the drilling mechanism 3.

[0029] Reference Figures 1 to 5The supporting mechanism 2 includes a supporting frame 21, a sliding plate 23, a first cylinder 24, and a rotating shaft 26. An electric slide rail 22 is provided on the supporting frame 21, and the sliding plate 23 is slidably installed on the electric slide rail 22. An extension groove 231 is provided on the sliding plate 23, and a through-hole 232 is provided in the extension groove 231. The first cylinder 24 is fixedly installed on the supporting frame 21, and a positioning block 25 is fixedly connected to the output end of the first cylinder 24. One end of the rotating shaft 26 is fixedly connected to the supporting frame 21. A support frame 11 is fixedly installed on the top of the base 1, and the rotating shaft 26 is rotatably installed on the support frame 11. The axis of the rotating shaft 26 is arranged horizontally.

[0030] In use, the conveying equipment conveys the throttling bolt, so that the throttling bolt falls vertically into the through-hole 232 on the sliding plate 23. Then, the sliding plate 23 slides into the bearing frame 21 along the electric slide rail 22. After that, the output end of the first cylinder 24 extends and drives the positioning block 25 to move synchronously. The positioning block 25 cooperates with the wall of the extension groove 231 to clamp and position the throttling bolt.

[0031] In summary, the automatic feeding and station switching of the throttling bolts can be achieved through the cooperation of the electric slide rail 22 and the sliding plate 23 on the support frame 21, effectively reducing manual intervention. The extension groove 231 and the through-hole 232 on the sliding plate 23 are used to allow the throttling bolts to fall accurately in a vertical arrangement. With the first cylinder 24 and the positioning block 25 connected to its output end, the positioning block 25 can work together with the groove wall of the extension groove 231 when it extends with the first cylinder 24 to quickly clamp and position the throttling bolts. This ensures the stability of the workpiece posture during processing and avoids the positioning deviation and low efficiency caused by manual clamping. At the same time, the support frame 21 and the throttling bolts that have been clamped and positioned on it can be smoothly rotated around the rotating shaft 26 in subsequent processes. This provides a structural basis for the same workpiece to complete the perforation processing in different directions in one clamping, reduces the cumulative error caused by multiple clamping, and improves the positional accuracy and overall processing efficiency of the multi-directional perforation processing of the throttling bolts.

[0032] Reference Figures 1 to 9The drilling mechanism 3 includes a lifting platform 31 and a movable plate 32. The lifting platform 31 is used to pull the movable plate 32 to move vertically. A fixed frame 33 and a mounting frame 34 are fixedly connected to one side of the movable plate 32. A drilling device 35 is fixedly mounted on the mounting frame 34. A second cylinder 36 is fixedly mounted on the top of the fixed frame 33. A translation block 37 is fixedly connected to the output end of the second cylinder 36. A guide rod 38 is fixedly connected to the top of the fixed frame 33. The axis of the guide rod 38 is arranged horizontally. The translation block 37 is sleeved on the surface of the guide rod 38. The translation block 37 and the guide rod 38 form a sliding guide fit along the axis of the guide rod 38. A roller 39 is rotatably mounted on one side of the translation block 37. The lifting platform 31 can drive the drilling device 35 to move up and down stably. The second cylinder 36, in conjunction with the guide rod 38, can precisely control the horizontal position of the roller 39, providing driving force and position guarantee for switching between different processing stages.

[0033] The triggering mechanism 4 includes a guide rod 41, a shifting block 42, and a connecting frame 46. The guide rod 41 is fixedly installed on the top of the base 1, and the axis of the guide rod 41 is arranged horizontally. The shifting block 42 is sleeved on the surface of the guide rod 41, and a compression spring 43 is sleeved on the surface of the guide rod 41. A first connecting rod 44 and a second connecting rod 45 are provided between the shifting block 42 and the rotating shaft 26. One end of the first connecting rod 44 is hinged to the top of the shifting block 42, and the other end of the first connecting rod 44 is hinged to one end of the second connecting rod 45. The other end of the second connecting rod 45 is fixedly connected to the rotating shaft 26. The connecting frame 46 is fixedly connected to one side of the shifting block 42. A first limiting plane 461, a triggering inclined surface 462, and a second limiting plane 463 are provided on the connecting frame 46. The second limiting plane 463 communicates with the triggering inclined surface 462. The first limiting plane 461 and the second limiting plane 463 can lock the displacement block 42 during drilling to ensure the stability of the bearing frame 21. The triggering inclined plane 462 uses the rolling of the roller 39 to precisely drive the displacement block 42 to translate and compress the compression spring 43. The first connecting rod 44 and the second connecting rod 45 drive the rotating shaft 26 to rotate, realizing the automatic flipping of the bearing frame 21. The compression spring 43 automatically resets after processing, making the entire reversing process precise, smooth and without the need for an additional power source.

[0034] In use, the output end of the second cylinder 36 extends and drives the translation block 37 to move along the guide rod 38. The translation block 37 moves and drives the roller 39 to move to the bottom of the first limiting plane 461 on the connecting frame 46. Then, the lifting platform 31 drives the movable plate 32 to move vertically upward. The fixed frame 33, the mounting frame 34 and the drilling equipment 35 also move vertically upward synchronously with the movable plate 32. During this process, the roller 39 rolls upward along the first limiting plane 461, and the drilling equipment 35 drills in from the tail end of the throttling bolt to complete the opening of the longitudinal hole on the throttling bolt. During the opening of the longitudinal hole, due to the cooperation between the roller 39 and the first limiting plane 461, the translation block 42 cannot move axially along the guide rod 41, and thus the bearing frame 21 cannot rotate around the axis of the rotating shaft 26, thereby ensuring the stability of the throttling bolt during the opening of the longitudinal hole. After the longitudinal hole is drilled, the lifting platform 31 drives the movable plate 32 to move vertically downward. The fixed frame 33, mounting frame 34, and drilling equipment 35 also move vertically downward synchronously with the movable plate 32 and return to their initial positions. Then, the output end of the second cylinder 36 shortens and drives the translation block 37 to move along the guide rod 38. The translation block 37 moves and drives the roller 39 to move to the bottom of the triggering inclined surface 462 on the connecting frame 46. After that, the lifting platform 31 drives the movable plate 32 to move vertically upward. The fixed frame 33, mounting frame 34, and drilling equipment 35 also move vertically upward synchronously with the movable plate 32. During this process, the roller 39 rolls upward along the triggering inclined surface 462. Under the pressure of the roller 39, the connecting frame 46 and the translation block 42 move synchronously along the guide rod 41, and the compression spring 43... The displacement block 42 contracts under pressure and its elasticity increases. The displacement block 42 moves and drives the second link 45 to rotate synchronously around the axis of the rotating shaft 26 through the first link 44. The rotating shaft 26 rotates synchronously around its own axis. The rotation of the rotating shaft 26 drives the support frame 21 to rotate synchronously around the axis of the rotating shaft 26. When the roller 39 leaves the triggering inclined surface 462 and enters the second limiting plane 463, the support frame 21 rotates ninety degrees around the rotating shaft 26. At this time, the throttling bolt changes from a vertical arrangement to a horizontal arrangement. After that, the roller 39 continues to roll upward along the second limiting plane 463. During this process, the position of the support frame 21 remains unchanged, the throttling bolt remains in a horizontal arrangement, and the drilling device 35 drills in from the side of the throttling bolt to complete the opening of the transverse hole on the throttling bolt. After the transverse hole is drilled, the lifting platform 31 drives the movable plate 32 to move vertically downward. The fixed frame 33, the mounting frame 34, and the drilling equipment 35 also move vertically downward synchronously with the movable plate 32 and return to their initial positions. The spring force of the compression spring 43 is released and drives the displacement block 42 to return to its initial position along the guide rod 41. The displacement block 42 moves and drives the bearing frame 21 to rotate synchronously around the axis of the rotating shaft 26 through the first connecting rod 44 and the second connecting rod 45. The throttling bolt returns from the horizontal arrangement state to the vertical arrangement state. After that, the workers remove the throttling bolt after drilling, and the conveying equipment continues to convey. The above steps are repeated, and so on.

[0035] In summary, by driving the movable plate 32 and the drilling equipment 35 on the fixed frame 33 and mounting frame 34 via the lifting platform 31, and coordinating with the second cylinder 36 on the fixed frame 33 to drive the translation block 37 to move horizontally, the roller 39 is driven to cooperate with the first limiting plane 461, the triggering inclined plane 462 and the second limiting plane 463 of the connecting frame 46, respectively. This achieves rigid locking of the bearing frame 21 during longitudinal drilling, automatic flipping during reversal, and stable holding again during transverse drilling. This process requires no manual intervention and only requires one clamping to complete the piercing process in both directions, eliminating the cumulative positioning error caused by multiple clamping. In particular, the first limiting plane 461 ensures that the displacement block 42 cannot move along the guide rod 41 during longitudinal drilling, so that the displacement block 42 is connected to the first connecting rod 46. The rotating shaft 26 and the support frame 21, which are linked to the second connecting rod 45, are fixed to ensure the stability of the workpiece during the tail end drilling. The triggering inclined plane 462 uses the rolling and squeezing action of the roller 39 to precisely drive the displacement block 42 to compress the compression spring 43. The first connecting rod 44 and the second connecting rod 45 drive the rotating shaft 26 to rotate 90 degrees, so that the workpiece is smoothly flipped to the horizontal. Then the second limiting plane 463 locks again to ensure that the posture is constant during the transverse drilling of the side, which effectively improves the positional accuracy and consistency of the hole diameter in all directions. After the transverse hole is completed, the compression spring 43 automatically resets, so that the support frame 21 rotates back to the initial state, which facilitates rapid unloading and continuous loading. The whole cycle is efficient and smooth, and it is suitable for high-precision, large-volume automated piercing processing of throttling bolts. It has outstanding practicality and economy.

[0036] It should be noted that in this application, the piercing mechanism 3 and the triggering mechanism 4 mechanically couple the 90° reversing motion of the support frame 21 with the lifting and feeding motion of the drilling equipment 35. Although servo motor or stepper motor solutions offer precise control, they require independent rotary power sources, drivers, encoders or limit switches, cables, and sealing protection structures. In the environment of cutting fluid splashing, metal shavings accumulation, and vibration accompanying high-speed piercing of throttle bolts, electrical components are susceptible to contamination and interference. Furthermore, they require programming and debugging and synchronization with the lifting and drilling motion, resulting in higher costs and maintenance difficulties. This application utilizes the existing lifting motion of the lifting platform 31 as the reversing power. Through the cooperation of the roller 39 with the first limiting plane 461, the triggering inclined plane 462, and the second limiting plane 463, as well as the deterministic kinematic chain formed by the first connecting rod 44, the second connecting rod 45, and the rotating shaft 26, the support frame 21 is rigidly locked during longitudinal drilling, automatically rotated 90° during reversing, and rigidly locked again during transverse drilling. Thus, without adding an independent rotation drive and sensor feedback system, the longitudinal and transverse hole processing can be completed continuously in one clamping.

[0037] It should also be noted that the driving force between the roller 39 and the triggering inclined surface 462 is not transmitted through friction, but rather the vertical movement of the lifting platform 31 is converted into the horizontal movement of the shift block 42 along the guide rod 41 by the inclined surface mechanism. The roller 39 can rotate freely around its own axis, and its main function is to reduce contact wear and movement resistance; what actually drives the movement of the shift block 42 is the axial component force along the guide rod 41 generated by the normal pressure of the roller 39 on the triggering inclined surface 462. This component force causes the shift block 42 to overcome the compression spring 43 and move linearly along the guide rod 41.

[0038] The working principle of this invention is as follows: The conveying equipment conveys the throttling bolt, so that the throttling bolt falls into the through-hole 232 on the sliding plate 23 in a vertical arrangement. Then, the sliding plate 23 slides into the bearing frame 21 along the electric slide rail 22. After that, the output end of the first cylinder 24 extends and drives the positioning block 25 to move synchronously. The positioning block 25 cooperates with the groove wall of the extension groove 231 to clamp and position the throttling bolt.

[0039] Subsequently, the output end of the second cylinder 36 extends and drives the translation block 37 to move along the guide rod 38. The translation block 37 moves and drives the roller 39 to move to the bottom of the first limiting plane 461 on the connecting frame 46. Then, the lifting platform 31 drives the movable plate 32 to move vertically upward. The fixed frame 33, the mounting frame 34 and the drilling equipment 35 also move vertically upward synchronously with the movable plate 32. During this process, the roller 39 rolls upward along the first limiting plane 461, and the drilling equipment 35 drills into the tail end of the throttling bolt to complete the opening of the longitudinal hole on the throttling bolt. During the opening of the longitudinal hole, due to the cooperation between the roller 39 and the first limiting plane 461, the translation block 42 cannot move axially along the guide rod 41, and thus the bearing frame 21 cannot rotate around the axis of the rotating shaft 26, thereby ensuring the stability of the throttling bolt during the opening of the longitudinal hole.

[0040] After the longitudinal hole is drilled, the lifting platform 31 drives the movable plate 32 to move vertically downward. The fixed frame 33, mounting frame 34, and drilling equipment 35 also move vertically downward synchronously with the movable plate 32 and return to their initial positions. Then, the output end of the second cylinder 36 shortens and drives the translation block 37 to move along the guide rod 38. The translation block 37 moves and drives the roller 39 to move to the bottom of the triggering inclined surface 462 on the connecting frame 46. After that, the lifting platform 31 drives the movable plate 32 to move vertically upward. The fixed frame 33, mounting frame 34, and drilling equipment 35 also move vertically upward synchronously with the movable plate 32. During this process, the roller 39 rolls upward along the triggering inclined surface 462. Under the pressure of the roller 39, the connecting frame 46 and the translation block 42 move synchronously along the guide rod 41, and the compression spring 43... The displacement block 42 contracts under pressure and its elasticity increases. The displacement block 42 moves and drives the second link 45 to rotate synchronously around the axis of the rotating shaft 26 through the first link 44. The rotating shaft 26 rotates synchronously around its own axis. The rotation of the rotating shaft 26 drives the support frame 21 to rotate synchronously around the axis of the rotating shaft 26. When the roller 39 leaves the trigger inclined surface 462 and enters the second limiting plane 463, the support frame 21 rotates ninety degrees around the rotating shaft 26. At this time, the throttling bolt changes from a vertical arrangement to a horizontal arrangement. After that, the roller 39 continues to roll upward along the second limiting plane 463. During this process, the position of the support frame 21 remains unchanged, the throttling bolt remains in a horizontal arrangement, and the drilling device 35 drills in from the side of the throttling bolt to complete the opening of the transverse hole on the throttling bolt.

[0041] After the transverse hole is drilled, the lifting platform 31 drives the movable plate 32 to move vertically downward. The fixed frame 33, the mounting frame 34, and the drilling equipment 35 also move vertically downward synchronously with the movable plate 32 and return to their initial positions. The spring force of the compression spring 43 is released and drives the displacement block 42 to return to its initial position along the guide rod 41. The displacement block 42 moves and drives the bearing frame 21 to rotate synchronously around the axis of the rotating shaft 26 through the first connecting rod 44 and the second connecting rod 45. The throttling bolt returns from the horizontal arrangement state to the vertical arrangement state. After that, the workers remove the throttling bolt after drilling, and the conveying equipment continues to convey. The above steps are repeated, and so on.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
