Synchronous vertical drilling device

Abstract

This application provides a synchronous vertical drilling device, including a processing table, two guide seats, and two sets of drills. The processing table is equipped with a positioning element and a first linear drive component to move the workpiece only in the forward-backward direction. The two guide seats are arranged side-by-side on both sides of the positioning element in the left-right direction, with their opposite sides being inclined surfaces and perpendicular to each other. The two sets of drills are slidably mounted on the inclined surfaces of the two guide seats, with the sliding direction of each set of drills parallel to the corresponding inclined surface, and are connected to a second linear drive component. During drilling, the positioning element limits the movement trajectory of the workpiece, and then the first linear drive component moves it to align the workpiece's processing position with the drills. Subsequently, the second linear drive component moves the drills, allowing for simultaneous drilling on both sides of the workpiece.

Description

Technical Field

[0001] This application belongs to the field of machining technology, specifically relating to a synchronous vertical drilling device. Background Technology

[0002] In the machining of mechanical structural components, it is often necessary to machine a system of holes at specific angles in spatial positions on the workpiece to meet the functional requirements of component installation, pipe connection, or transmission linkage. Among these, machining a set of holes with mutually perpendicular central axes is particularly common.

[0003] In existing technologies, vertical drilling of workpieces is performed in a sequential manner. Specifically, the workpiece is first clamped on the machine tool, and the first hole (e.g., a horizontal hole) is machined. Then, the workpiece is unloaded from the fixture, its orientation is adjusted (e.g., rotated 90 degrees), and it is clamped again. Then, based on the drawing or the machine tool coordinate system, a second hole perpendicular to the first hole is machined.

[0004] The inventors discovered that the above processing method has significant limitations. Because the workpiece is difficult to precisely position on the theoretical datum during the two clamping operations, the central axes of the two machined holes cannot guarantee an ideal perpendicular relationship, resulting in perpendicularity deviation. Furthermore, when the designed positions of the two holes require precise spatial intersection, the cumulative error from the two clamping operations directly causes the intersection point of the two holes to shift, resulting in misalignment. This deviation can lead to assembly interference, reduced connection strength, and affect the smoothness of fluid channels or the movement trajectory of transmission components, ultimately impacting the product quality and performance of the structural components. Utility Model Content

[0005] This application provides a synchronous vertical drilling device, which aims to improve the stability of the workpiece processing and ensure the product quality and performance of structural components.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: A synchronous vertical drilling device is provided, comprising: A processing table is provided with a positioning component for contacting a workpiece; when the positioning component is in contact with the workpiece, the workpiece has a degree of freedom to move in the front-back direction; and the processing table is also provided with a first linear drive component for driving the workpiece to move in the front-back direction. Two guide seats are arranged side-by-side on both sides of the positioning member in a left-right direction, and both are fixedly connected to the processing table. The opposite sides of the two guide seats are inclined surfaces and perpendicular to each other; and Two sets of drill bits are slidably mounted on the inclined surfaces of the two guide seats, and the sliding direction of each set of drill bits is parallel to the corresponding inclined surface; and each set of drill bits is driven by a second linear drive component for moving it.

[0007] In one possible implementation, the positioning member has a cavity that extends through the front-rear direction for inserting the workpiece, and the side of the positioning member facing each of the drill bits is also provided with a reserved hole communicating with the cavity. The reserved hole is used for the machining section of the drill bit to pass through in order to contact and machine the workpiece.

[0008] In one possible implementation, two recessed grooves are formed on the inner bottom surface of the cavity. The two recessed grooves are coaxially arranged with the two reserved holes, and both are used for the insertion of the processing part.

[0009] In one possible implementation, the upper side of the processing table has multiple threaded grooves; the positioning member has multiple positioning holes extending in the vertical direction, and the multiple positioning holes are adapted to communicate with the multiple threaded grooves one-to-one; the positioning member further includes: Multiple hand-tightening bolts are inserted into multiple positioning holes in a one-to-one correspondence, and are adapted to be threadedly connected to multiple threaded grooves in a one-to-one correspondence.

[0010] In one possible implementation, the drill string includes: A sliding plate, slidably disposed on the inclined surface of the guide seat and drively connected to the second linear drive member, is adapted to move along the inclined direction of the inclined surface of the guide seat; and The drill rod is rotatably mounted on the sliding plate, with its axial direction parallel to the inclined surface of the guide seat, and the drill rod is also connected to a first rotary motor for driving its rotation.

[0011] In one possible implementation, the guide seat has an internally hollow structure and a strip-shaped hole is provided on its inclined surface; The sliding plate has a protrusion that passes through the strip hole and extends into the inside of the guide seat. The second linear drive component includes a linear cylinder that is fixedly disposed inside the guide seat and is throttle connected to the protrusion.

[0012] In one possible implementation, the first linear drive component includes: A translational seat is slidably disposed on the upper side of the machining table in the front-to-back direction, and has clamping structures for engaging with the front and rear ends of the workpiece; furthermore, the translational seat also has a first transmission nut whose axial direction is parallel to the front-to-back direction; and A transmission screw is rotatably mounted on the processing table and is threadedly connected to the first transmission nut. The transmission screw is also connected to a second rotary motor for driving its rotation.

[0013] In one possible implementation, the clamping structure includes: Two clamping plates are respectively disposed on the front and rear sides of the positioning member, and both are slidably connected to the translational seat in the front-rear direction; and each clamping plate is provided with a second transmission nut whose axial direction is parallel to the front-rear direction; and A double-ended screw is rotatably mounted on the translational seat, and has two threaded portions with opposite thread directions, and the two threaded portions are respectively threadedly connected to the two second transmission nuts.

[0014] In one possible implementation, elastic pads are provided on the opposite sides of the two clamping plates. These elastic pads are used to contact the end face of the workpiece facing the front-back direction and generate elastic deformation.

[0015] In one possible implementation, the translational seat has two guide grooves arranged side by side in the front-rear direction; both clamps have bosses, and the two bosses are respectively embedded in the two guide grooves, and each second transmission nut is disposed on the corresponding boss; The translational seat also has a through hole that runs through the front and rear directions. The through hole is connected to the two guide grooves, and the double-ended screw is inserted into the through hole. One end of the double-ended screw extends out of the translational seat and has a handle that extends radially outward.

[0016] In this embodiment of the application, by setting two guide seats with a specific tilt angle and perpendicular to each other, and sliding two sets of drill bits on their tilt surfaces respectively, it is realized that during a single clamping process, the two sets of drill bits are driven by two second linear drive components respectively, so that the drill bits can simultaneously perform drilling operations on the workpiece in two directions along their respective trajectories.

[0017] In the above process, the workpiece is fixed to a reference by the positioning component and moved only by the first linear drive component in the back-and-forth direction to align with the machining position. Since the inclined surfaces of the two guide seats are pre-set to be perpendicular to each other in space, this fundamentally ensures that the feed directions (i.e., drilling axes) of the two sets of drills remain perpendicular in space. Therefore, no matter where the workpiece is moved to, the two holes machined by this device can guarantee ideal perpendicularity, completely eliminating the perpendicularity deviation caused by inconsistent clamping references in traditional sequential machining.

[0018] Meanwhile, since the two holes are machined simultaneously after the workpiece is clamped and positioned once, the theoretical intersection point of the two holes in space is determined solely by the mechanical structure of the device itself (the angle between the inclined surfaces of the guide seat and the relative position of the drill bit) and the single positioning of the workpiece, completely avoiding the cumulative errors caused by two clamping and two tool setting operations in traditional processes. This effectively prevents misalignment of the intersection point of the two holes and ensures the spatial positional accuracy of the hole system.

[0019] The synchronous vertical drilling device provided in this embodiment, compared with the prior art, not only significantly improves production efficiency through one-time synchronous processing, but also fundamentally solves the core technical problems of poor perpendicularity of hole systems and low accuracy of spatial intersection points caused by sequential processing. This device ensures high stability in the workpiece processing and product consistency, thereby effectively improving the assembly quality, connection strength, and performance of structural components, providing a reliable guarantee for the mass production of high-precision vertical hole systems.

Therefore, they should not be construed as limitations on this application.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0026] Please refer to the following: Figures 1 to 14 The synchronous vertical drilling device provided in this application will now be described.

[0027] The synchronous vertical drilling device proposed in this application includes a processing table 1, two guide seats 2, and two sets of drill bits 3.

[0028] The processing table 1 is typically fixed on any support surface within the processing area, and its upper surface must remain horizontal. In this embodiment, the processing table 1 is provided with a positioning member 4 for contacting the workpiece 100; when the positioning member 4 is in contact with the workpiece 100, the workpiece 100 has the freedom to move in the front-back direction. Furthermore, the processing table 1 is also provided with a first linear drive member 5 for driving the workpiece 100 to move in the front-back direction.

[0029] Two guide seats 2 are arranged side by side on both sides of the positioning member 4 in the left-right direction, and both are fixedly connected to the processing table 1. The opposite sides of the two guide seats 2 are inclined surfaces and perpendicular to each other; that is, the inclined surface of each guide seat 2 maintains a 45-degree angle with the vertical surface parallel to the front-back direction.

[0030] Two sets of drill bits 3 are slidably mounted on the inclined surfaces of the two guide seats 2. The sliding direction of each set of drill bits 3 is parallel to the corresponding inclined surface, and each set of drill bits 3 is connected to a second linear drive component 6 for driving its movement.

[0031] In this embodiment of the application, by setting two guide seats 2 with a specific tilt angle and perpendicular to each other, and sliding two sets of drill bits 3 on their tilt surfaces respectively, it is realized that during a single clamping process, the two sets of drill bits 3 are driven by two second linear drive components 6 respectively, so that the drill bits 3 can simultaneously perform drilling operations on the workpiece 100 in two directions along their respective trajectories.

[0032] In the above process, the workpiece 100 is fixed to a reference by the positioning element 4 and moved only by the first linear drive component 5 in the front-back direction to align with the machining position. Since the inclined surfaces of the two guide seats 2 are pre-set to be perpendicular to each other in space, this fundamentally ensures that the feed directions (i.e., drilling axes) of the two sets of drills 3 remain perpendicular in space. Therefore, no matter where the workpiece 100 is moved to, the two holes machined by this device can guarantee ideal perpendicularity, completely eliminating the perpendicularity deviation caused by the inconsistency of the two clamping references in traditional sequential machining.

[0033] Meanwhile, since the two holes are machined simultaneously after the workpiece 100 is clamped and positioned once, the theoretical intersection point of the two holes in space is determined solely by the mechanical structure of the device itself (the included angle of the inclined surfaces of the guide seat 2 and the relative position of the drill bit 3) and the single positioning of the workpiece 100, completely avoiding the cumulative errors caused by two clamping and two tool setting operations in traditional processes. This effectively prevents misalignment of the intersection point of the two holes and ensures the spatial positional accuracy of the hole system.

[0034] The synchronous vertical drilling device provided in this embodiment, compared with the prior art, not only significantly improves production efficiency through one-time synchronous processing, but also fundamentally solves the core technical problems of poor perpendicularity of the hole system and low accuracy of spatial intersection points caused by sequential processing. This device ensures high stability and product consistency during the workpiece 100 machining process, thereby effectively improving the assembly quality, connection strength, and performance of structural components, providing a reliable guarantee for the mass production of high-precision vertical hole systems.

[0035] In some embodiments, such as Figure 6 and Figure 7 As shown, the positioning member 4 has a cavity 41 that runs through the front and rear directions; in actual use, the cavity 41 is used for inserting the workpiece 100.

[0036] It should be noted that in this embodiment, the positioning element 4 is detachably connected to the processing table 1, and each positioning element 4 has a unique cavity 41 to adapt to workpieces 100 with different shapes.

[0037] The positioning element 4 also has a reserved hole 42 on the side facing each drill bit 3, which communicates with the cavity 41. The reserved hole 42 is used for the processing part of the drill bit 3 to pass through, so as to contact and process the workpiece 100.

[0038] By adopting the above technical solution, the drill bit 3 is provided with precise guidance and avoidance space, ensuring that the processing path is accurate and does not interfere with the positioning part 4.

[0039] In some embodiments, such as Figure 6 and Figure 7As shown, two recessed grooves 43 are formed on the inner bottom surface of the cavity 41, and the two recessed grooves 43 are coaxially arranged with the two reserved holes 42 respectively.

[0040] In practical use, each recess 43 is used to allow the machining section of the drill bit 3 on the same side to be inserted. This design allows the machining section of the drill bit 3 to continue to penetrate a certain distance after completing the through hole 513, ensuring that the hole wall is smooth and completely penetrated, while accommodating any chips that may be generated.

[0041] In some embodiments, such as Figure 5 As shown, the upper side of the processing table 1 is provided with multiple threaded grooves 11, and the positioning member 4 has multiple positioning holes 44 that run through in the vertical direction; after the positioning member 4 is aligned with the processing table 1, the multiple positioning holes 44 are adapted to communicate with the multiple threaded grooves 11 one by one.

[0042] Based on the foregoing, the positioning component 4 also includes multiple hand-twisted bolts 45.

[0043] Multiple hand-tightening bolts 45 are inserted into multiple positioning holes 44 in a one-to-one correspondence, and are suitable for threaded connection with multiple threaded grooves 11 in a one-to-one correspondence.

[0044] By tightening the hand-operated bolt 45, the positioning element 4 can be quickly pressed and fixed at a specific position on the processing table 1; this design facilitates the adjustment of the installation position of the positioning element 4 according to the size of the workpiece 100, enhancing the adaptability of the device.

[0045] In some embodiments, such as Figure 2 and Figure 13 As shown, the drill string 3 includes a sliding plate 31 and a drill rod 32.

[0046] The sliding plate 31 is slidably disposed on the inclined surface of the guide seat 2, and the sliding plate 31 is connected to the second linear drive member 6 for transmission, so as to be suitable for moving along the inclined direction of the inclined surface of the guide seat 2.

[0047] The drill rod 32 is rotatably mounted on the sliding plate 31. Both the axial direction and the rotational direction of the drill rod 32 are parallel to the inclined surface of the guide seat 2. Based on this feature, the drill rod 32 is also connected to a first rotary motor 321 for driving its rotation.

[0048] It should be noted that the drilling end of drill rod 32 here is the aforementioned machining part.

[0049] This structure separates the linear feed motion of the drill bit 3 from the rotary cutting motion. The second linear drive component 6 provides stable feed power, while the first rotary motor 321 provides the main cutting motion, thereby achieving efficient and smooth drilling operations.

[0050] In some embodiments, such as Figure 4 and Figure 14As shown, the guide seat 2 has a hollow internal structure. A strip hole 21 communicating with its internal space is provided on the inclined surface of the guide seat 2, and the length direction of the strip hole 21 is parallel to the inclined surface of the guide seat 2.

[0051] The sliding plate 31 has a protrusion 311 that passes through the strip hole 21 and extends into the inside of the guide seat 2; based on this feature, the aforementioned second linear drive member 6 includes a linear cylinder fixedly disposed inside the guide seat 2, which is connected to the protrusion 311 in a transmission manner.

[0052] This layout accommodates the second linear drive component 6 inside the guide seat 2, ensuring a compact structure and efficient use of space. At the same time, the cooperation between the protrusion 311 and the strip hole 21 not only transmits the driving force but also guides and limits the sliding plate 31, ensuring the accuracy of the sliding plate 31's movement trajectory.

[0053] In some embodiments, such as Figure 8 As shown, the first linear drive component 5 includes a translation seat 51 and a transmission screw 52.

[0054] The translational seat 51 is slidably disposed on the upper side of the machining table 1 in the front-to-back direction, and the translational seat 51 is provided with a clamping structure 7 for connecting with the front and rear ends of the workpiece 100. In addition, the translational seat 51 is also provided with a first transmission nut 511 whose axial direction is parallel to the front-to-back direction.

[0055] The transmission screw 52 is rotatably mounted on the processing table 1. The transmission screw 52 is threadedly connected to the first transmission nut 511, and the transmission screw 52 is connected to a second rotary motor 521 for driving its rotation.

[0056] By adopting the above technical solution, the transmission screw 52 is driven to rotate by the second rotary motor 521, which can be converted into the precise linear movement of the translation seat 51, thereby driving the workpiece 100 to adjust its position in the front and rear directions and achieving alignment of different processing stations.

[0057] In some embodiments, such as Figure 10 and Figure 12 As shown, the clamping structure 7 includes two clamping plates 71 and a double-ended screw 72.

[0058] Two clamping plates 71 are respectively disposed on the front and rear sides of the positioning member 4, and both clamping plates 71 are slidably connected to the translational seat 51 in the front-rear direction. In addition, each clamping plate 71 is provided with a second transmission nut 711 whose axial direction is parallel to the front-rear direction.

[0059] The double-ended screw 72 is rotatably mounted on the translation seat 51. This double-ended screw 72 has two threaded portions with opposite thread directions.

[0060] After the structure is assembled, the two threaded parts are respectively threadedly connected to the two second transmission nuts 711. At this time, by rotating the double-ended screw 72, the two clamping plates 71 can be driven to move synchronously towards or away from each other, thereby realizing the rapid centering and clamping of the workpiece 100. This design ensures that the reference of the workpiece 100 is always consistent with the positioning part 4 during the clamping process.

[0061] In some embodiments, such as Figure 10 and Figure 12 As shown, elastic pads 712 are provided on the opposite sides of the two clamping plates 71. The elastic pads 712 are used to contact the end face of the workpiece 100 facing the front-back direction and generate elastic deformation.

[0062] The elastic pad 712 can absorb part of the impact and increase the friction when clamping the workpiece 100. This can effectively prevent the surface of the workpiece 100 from being damaged by clamping, and also enhance the stability of clamping, thus preventing the workpiece 100 from sliding during the processing.

[0063] In some embodiments, such as Figures 10 to 12 As shown, the translational base 51 has two guide grooves 512 arranged side by side in the front-rear direction. Based on this, both clamping plates 71 have bosses 713, and the two bosses 713 are respectively embedded in the two guide grooves 512.

[0064] In this embodiment, each second transmission nut 711 is provided on a corresponding boss 713; and the translation seat 51 also has a through hole 513 extending in the front-back direction, which communicates with two guide grooves 512, and the aforementioned double-ended screw 72 is inserted into the through hole 513.

[0065] After the structure is assembled, one end of the double-headed screw 72 extends out of the translation seat 51 and has a handle 721 extending radially outward.

[0066] The engagement of the boss 713 and the guide groove 512 provides precise guidance for the movement of the clamping plate 71 and prevents it from deflecting; the handle 721 allows the operator to manually rotate the double-ended screw 72 to quickly clamp and release the workpiece 100.

[0067] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
