Description

Technical Field

[0001] The present disclosure relates to the technical field of drilling equipment, and in particular to a cylindrical drilling processing equipment. Background Art

[0002] Large cylinders are widely used in many industries such as aviation, petrochemicals, electric power, and shipbuilding. During the manufacturing process of large cylinders, holes of different positions and sizes on the cylinders need to be precisely processed to meet the requirements of subsequent component installation and system operation.

[0003] Currently, vertical lathes or horizontal lathes are commonly used to process holes on large cylinders. However, vertical lathes are mainly suitable for processing holes at the ends of the cylinder or within a certain range near the ends. Due to the limitations of their own structure and movement mode, vertical lathes have difficulty in effectively processing holes in the middle of the cylinder, away from the center of rotation, or at any circumferential angle. When processing with a horizontal lathe, the cylinder is usually placed horizontally, and its processing range is also limited by the tool's movement trajectory and the structural layout of the equipment, making it impossible to flexibly position and process holes at any position on the cylinder. This limitation leads to the fact that in actual production, when it is necessary to process holes at specific positions on the cylinder, it is often necessary to frequently replace the tooling fixture, or even clamp the workpiece multiple times. This not only consumes a lot of time and labor costs, but also easily affects the processing accuracy due to positioning errors caused by multiple clamping, and reduces processing efficiency.

[0020] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0021] In the present disclosure, unless otherwise stated, directional words such as "top" and "bottom" refer to the "top" and "bottom" of the present disclosure in the height direction when in use, and the X-axis, Y-axis and Z-axis directions refer to the attached drawings. Figure 1 In the directions indicated in the figure, the terms "first," "second," and the like are used in this disclosure to distinguish one element from another and do not imply order or importance. In the following description, when referring to the drawings, unless otherwise indicated, the same reference numerals in different drawings represent the same or similar elements. The above definitions are intended only to explain and illustrate this disclosure and should not be construed as limiting the disclosure.

[0022] According to an exemplary embodiment of the present disclosure, referring to Figures 1 to 3 As shown, a cylindrical drilling processing equipment is provided, including: a base 1, which is provided with two symmetrical support frames 2; a crossbeam 3, which is slidably mounted on the two support frames 2 along the X-axis direction, and the crossbeam 3 is driven and connected to the X-axis drive assembly 21 arranged on the support frame 2, and the crossbeam 3 is provided with a saddle 31 and a Y-axis drive assembly that drives the saddle 31 to move along the Y-axis direction; a Z-axis drive assembly 4, which is installed on the saddle 31, and the Z-axis drive assembly 4 is driven and connected to a swing head 6 for installing a drilling tool 5, and the swing head 6 is driven to move along the Z-axis direction through the Z-axis drive assembly 4; a positioning seat 7, which is rotatably arranged on the base 1 and is used to carry and fix the cylindrical body 8 to be processed, and a rotation drive assembly is provided on the base 1, and the positioning seat 7 is transmission-connected to the rotation drive assembly to drive the cylindrical body 8 to be processed to rotate.

[0023] Through the above technical solution, in the barrel drilling processing equipment disclosed in the present invention, the base 1 is provided with two symmetrical support frames 2, which provide stable and reliable support for the entire equipment and ensure the stability of the equipment during operation. On this basis, since the crossbeam 3 is slidably mounted on the support frame 2 along the X-axis direction, the slide saddle 31 moves along the Y-axis direction on the crossbeam 3 through the Y-axis drive assembly, and the Z-axis drive assembly drives the swing head 6 to move along the Z-axis direction, so that the drilling tool 5 can be freely and flexibly positioned in three-dimensional space. For example, holes in the middle of the barrel, away from the center of rotation, and at any circumferential angle can be drilled, which greatly expands the processing range; in addition, the present application rotatably sets the positioning seat 7 on the base 1 and is driven to rotate by the rotation drive assembly, so that the barrel 8 to be processed can achieve circumferential rotation, so that the drilling tool 5 can continuously process holes at different circumferential angles during the rotation of the barrel, avoiding multiple adjustments to the barrel position or replacement of tooling fixtures, reducing the number of clamping times, thereby avoiding positioning errors caused by multiple clamping, effectively improving processing accuracy, while saving a lot of time and labor costs, and significantly improving processing efficiency.

[0024] The present disclosure is provided with an intelligent control system. The above-mentioned X-axis drive assembly 21 and Y-axis drive assembly can be set to any one of the gear rack type, screw nut type and synchronous belt type drive assemblies, as long as the X-axis drive assembly 21 and Y-axis drive assembly can be controlled by the intelligent control system to drive the crossbeam 3 and the saddle 31 to move.

[0025] According to an exemplary embodiment of the present disclosure, referring to Figure 1 and Figure 4 As shown, the barrel drilling processing equipment can also include a calibration component, which includes a mounting plate 9. The mounting plate 9 is installed at the connection between the swing head 6 and the drill 5, and the central axis of the mounting plate 9 is parallel to the axis of the output shaft 51 of the drill 5. Distance sensors are respectively provided on the four sides of the mounting plate 9. The four distance sensors are located on the same horizontal plane and are used to detect the distance between the corresponding distance sensors and the barrel 8 to be processed. The distance between the drill 5 and the barrel is detected in real time by the distance sensors on the mounting plate 9. The position of the drill 5 can be calibrated before processing to ensure that the drill 5 is in the accurate processing position and the axis of the hole is perpendicular to the barrel surface, thereby improving processing accuracy and reducing processing errors caused by position deviation.

[0026] According to an exemplary embodiment of the present disclosure, referring to Figure 1 、 Figure 2 and Figure 4 As shown, the four ranging sensors may be the first sensor 91, the second sensor 92, the third sensor 93 and the fourth sensor 94 in the circumferential direction, the first sensor 91 and the third sensor 93 are arranged symmetrically, and the second sensor 92 and the fourth sensor 94 are arranged symmetrically. Figure 5 As shown, before drilling, the swing head 6 rotates around the axis a so that the distances measured by the first sensor 91 and the third sensor 93 are equal. At this time, the axis of the output shaft 51 is perpendicular to the axis of the cylinder 8 to be processed; then, through the cooperation of the X-axis drive assembly 21 and the Y-axis drive assembly, the saddle 31 is moved so that the distances measured by the second sensor 92 and the fourth sensor 94 are the same, and the distances measured by the first sensor 91 and the third sensor 93 are the same. At this time, the axis of the output shaft 51 is perpendicular to the surface of the cylinder 8 to be processed, ensuring that the drill tool 5 is in an accurate processing position. At the same time, the intelligent control system can calculate the drilling feed depth based on the distance from the cylinder surface to the output shaft 51 measured by the first sensor 91 and the third sensor 93, thereby ensuring the accuracy of drilling.

[0027] According to an exemplary embodiment of the present disclosure, the swing head 6 can be configured as a single-axis swing head or a dual-axis swing head. Figure 1 、 Figure 4 、 Figure 5 and Figure 6 As shown, the single-axis swing head is configured to: be able to drive the drilling tool 5 to rotate around the Y axis or the X axis; Figure 3 、 Figure 7 、 Figure 8 and Figure 9 As shown, the dual-axis swing head is configured to be able to drive the drilling tool 5 to rotate around the Y axis or the X axis, and to drive the drilling tool 5 to rotate around the Z axis.

[0028] According to an exemplary embodiment of the present disclosure, referring to Figures 4 to 6 As shown, the single-axis swing head includes a swing head box 61, a first power device 62 and a C-axis box 63. The drilling tool 5 is installed on the C-axis box 63. The swing head box 61 is fixedly connected to the Z-axis drive assembly 4, and a first power device 62 is provided on the swing head box 61. The first power device 62 is transmission-connected to the C-axis box 63 and drives the C-axis box 63 and the drilling tool 5 to rotate synchronously.

[0029] In this disclosure, reference is made to Figure 5As shown, the first power unit 62 may include a cooling jacket 621, a stator 622, a brake disc 623, a brake shaft 624, a rotor jacket 625, a rotor 626, a bearing 627, and a flange 628. The axis of the rotor 626 is perpendicular to the axis of the output shaft 51. The cooling jacket 621 and the brake disc 623 are installed in the swing head box 61. The stator 622 is fixed in the cooling jacket 621. The brake shaft 624 is fixedly connected to one end of the rotor jacket 625. The inner hole of the rotor jacket 625 is equipped with the rotor 626. The swing head box 61 and The flange 628 is rotatably connected through the bearing 627, and the flange 628 and the brake shaft 624 are fixedly connected. The output shaft 51 housing is connected to the side of the flange 628 away from the swing head housing 61. The tool 52 on the drilling tool 5 can be set as a multi-axis power tool 52. When the rotor 626 rotates, it drives the rotor sleeve 625, the brake shaft 624, the flange 628, the output shaft 51 housing, and the drilling tool 5 to rotate synchronously around the axis of the rotor 626, thereby realizing the swing adjustment of the tool 52 in the vertical plane to adapt to drilling processing at various angles.

[0030] According to an exemplary embodiment of the present disclosure, referring to Figures 7 to 9 As shown, the dual-axis swing head includes a swing head base 64, a second power unit 65, an A-axis housing 66, a third power unit 67, and a C-axis housing 63. The drilling tool 5 is mounted on the C-axis housing 63. The swing head base 64 is fixedly connected to the Z-axis drive assembly 4. The swing head base 64 is equipped with a second power unit 65, which is transmission-connected to the A-axis housing 66 and drives the A-axis housing 66 to rotate about the Z-axis. The A-axis housing 66 is equipped with a third power unit 67, which is transmission-connected to the C-axis housing 63 and drives the C-axis housing 63 and the drilling tool 5 to rotate about the Y-axis or X-axis. The second power unit 65 enables the drilling tool 5 to rotate in the horizontal plane, while the third power unit 67 drives the tool 52 to rotate in the vertical plane. In this way, through the coordinated operation of the second power unit 65 and the third power unit 67, the angle of the drilling tool 5 can be more flexibly adjusted to meet various complex drilling processing requirements, thereby improving the processing capacity and application range of the equipment.

[0031] It should be noted that when a dual-axis swing head is used, the drilling requirements of any angle of the cylinder can be met through the coordination of the second power device 65 and the third power device 67. Therefore, in this case, the positioning seat 7 does not need to be rotated, which improves the flexibility of use.

[0032] In the present disclosure, the second power device 65 and the third power device 67 can be set with reference to the first power device 62 to drive the A-axis box 66 and the C-axis box 63 to rotate, which will not be described in detail here.

[0033] According to an exemplary embodiment of the present disclosure, referring to Figure 1 and Figure 3As shown, there are two slide saddles 31, which are spaced apart on the crossbeam 3. Both slide saddles 31 are equipped with a Z-axis drive assembly 4 and a swing head 6 in transmission connection with the Z-axis drive assembly 4. The two slide saddles 31 allow two drilling tools 5 to be installed simultaneously, achieving dual-station processing, greatly improving processing efficiency and enabling more drilling tasks to be completed in the same time.

[0034] According to an exemplary embodiment of the present disclosure, referring to Figure 6 、 Figure 9 and Figure 10 As shown, the Z-axis drive assembly 4 includes a large ram 41, a first motor-screw drive mechanism 42, a small ram 43, and a second motor-screw drive mechanism. The large ram 41 is slidably connected to the corresponding saddle 31, and the large ram 41 is transmission-connected to the first motor-screw drive mechanism 42 so that the large ram 41 moves relative to the corresponding saddle 31 along the Z-axis direction; the small ram 43 is slidably disposed on the large ram 41, and the small ram 43 is transmission-connected to the second motor-screw drive mechanism so that the small ram 43 moves relative to the large ram 41 along the Z-axis direction. The swing head 6 is connected to the bottom end of the small ram 43. In the above technical solution, the Z-axis drive assembly 4 adopts a two-stage structure of a large ram 41 and a small ram 43. The large ram 41 and the small ram 43 are driven to move by the first motor-screw drive mechanism 42 and the second motor-screw drive mechanism, respectively, so as to achieve high-precision and wide-range motion control in the Z-axis direction and meet the drilling requirements of more cylinders with different heights. Among them, the large slide 41 can achieve a larger stroke movement to meet the drilling requirements of different depth positions of the cylinder, while the small slide 43 can achieve more precise fine-tuning to improve the precision and accuracy of drilling.

[0035] According to an exemplary embodiment of the present disclosure, referring to Figure 6 、 Figure 9 and Figure 10 As shown, a mounting base 44 is provided on the side of the large ram 41. The second motor-screw drive mechanism includes a motor 45, a screw 46, and a belt transmission mechanism 47. The motor 45 is mounted on the mounting base 44. The screw 46 is pivotally connected to the large ram 41 in parallel and is transmission-connected to the motor 45 via the belt transmission mechanism 47. The small ram 43 is connected to a screw nut that is threadedly engaged with the screw 46. Through the above technical solution, since the screw 46 is transmission-connected to the motor 45 via the belt transmission mechanism 47, the overall installation height of the second motor-screw drive mechanism is reduced compared to a direct drive connection between the motor 45 and the screw 46. This makes it possible to increase the height travel of the small ram 43 in the limited space, thereby meeting the drilling requirements of more cylinders of different heights, expanding the scope of use, and reducing the overall height of the equipment.

[0036] According to an exemplary embodiment of the present disclosure, referring to Figure 1 、 Figure 3and Figure 10 As shown, the barrel drilling processing equipment also includes a tool magazine 10, and the tool magazine 10 is respectively provided on the two support frames 2. The tool magazine 10 includes a movable seat 11, a cutter disc 12 and a movable drive member 13. The movable seat 11 is slidingly provided on the corresponding support frame 2 along the Y-axis direction, and the cutter disc 12 is rotatably provided on the movable seat 11. The movable drive member 13 is installed on the support frame 2 and is driven and connected to the movable seat 11 to drive the cutter disc 12 to extend or retract to the corresponding support frame 2 through the movable seat 11. Here, the setting of the tool magazine 10 can store a variety of cutting tools 52 of different specifications. When the cutting tool 52 needs to be replaced, the movable drive member 13 drives the movable seat 11 and the cutter disc 12 to extend, so that the replacement of the cutting tool 52 can be realized conveniently and quickly, which can meet the requirements of different processing technologies for the cutting tool 52.

[0037] In this disclosure, reference is made to Figure 2 As shown in FIG, a plurality of tool holders 121 are arranged along the circumferential direction on the cutter head 12 for clamping and fixing various cutters 52. Figure 10 As shown in , when changing the tool, the mobile driving component 13 drives the cutter disc 12 to extend out of the support frame 2, and the tool clamp 121 with an empty tool position is aligned with the tool 52 on the output shaft 51. The tool clamp 121 clamps the tool 52, and the swing head 6 releases the tool 52 and moves upward. After that, the cutter disc 12 rotates and aligns the tool 52 to be installed on the cutter disc 12 with the axis of the output shaft 51. The output shaft 51 of the swing head 6 moves downward to grab the tool handle of the tool 52. Finally, the mobile driving component 13 drives the cutter disc 12 to retract into the support frame 2 to complete the tool change.

[0038] Please refer to Figures 1 to 10 The following describes the use of the barrel drilling processing equipment disclosed in the present invention, taking a single-axis swing head as an example, as follows: First, place the cylinder 8 to be processed on the positioning seat 7 of the base 1, and fix the cylinder 8 to be processed by the fixture (such as chuck, pressure plate, etc.) on the positioning seat 7 to ensure that the axis of the cylinder 8 to be processed coincides with the rotation axis of the positioning seat 7; Start the rotation drive assembly on the base 1 to drive the cylinder 8 to be processed to rotate to a preset processing position, wherein the rotation drive assembly can be an electric motor; Afterwards, the X-axis drive assembly 21 (such as a screw-nut mechanism) on the support frame 2 drives the crossbeam 3 to move along the X-axis direction, adjusting the horizontal position of the crossbeam 3 so that the drill 5 is initially aligned with the area to be processed of the cylinder 8 to be processed. The Y-axis drive assembly on the crossbeam 3 drives the saddle 31 to move along the Y-axis direction to further adjust the horizontal position of the drill 5. The Z-axis drive assembly 4 drives the swing head 6 to move up and down along the Z-axis to determine the vertical height of the drill 5. Next, the swing head 6 drives the drill 5 to rotate around its axis, making the distances between the cylinder detected by the first sensor 91 and the third sensor 93 equal, ensuring that the axis of the output shaft 51 is perpendicular to the cylinder axis. Then, through the linkage of the X and Y axes, the distances measured by the second sensor 92 and the fourth sensor 94 are made the same, ensuring that the axis of the output shaft 51 is perpendicular to the cylinder surface. At this time, the intelligent control system calculates the drilling feed depth based on the distance measurement data. Finally, drilling is performed. Specifically, the first power device 62 in the swing head housing 61 drives the C-axis housing 63 to rotate, driving the drill 5 to swing around the X-axis (can also be set to around the Y-axis) to the target angle. The Z-axis drive assembly 4 controls the feed of the drill 5 along the Z-axis. At the same time, the positioning seat 7 rotates the drive assembly to drive the cylinder 8 to be processed to rotate, thereby achieving drilling at any circumferential position of the cylinder 8 to be processed. When the tool 52 needs to be replaced, the tool 52 can be replaced according to the above tool changing process.

[0039] When using a dual-axis swing head, the other steps are the same as those of a single-axis swing head. The difference is that the dual-axis linkage of the dual-axis swing head can make the drill 5 align with the surface of the cylinder at any angle. Therefore, there is no need to rotate the positioning seat 7 and adjust the angle of the cylinder 8 to be processed. It is possible to directly complete the multi-angle drilling of space. In addition, when using a dual-axis swing head for drilling, refer to Figure 8 As shown, the second power device 65 drives the A-axis box 66 to rotate around the Z-axis to adjust the angle of the drilling tool 5 in the horizontal plane; the third power device 67 drives the C-axis box 63 to rotate around the X-axis (can also be set to around the Y-axis) to achieve angle adjustment in the vertical plane.

[0040] It should be noted that two saddles 31 are provided on the crossbeam 3 of the present invention, and the swing heads 6 of the Z-axis drive assemblies 4 on the two saddles 31 can be respectively installed with drilling tools 5 of different specifications (such as large-diameter drill bits and small-diameter drill bits). In this way, holes can be drilled at different positions of the cylinder 8 to be processed at the same time, thereby improving processing efficiency.
