Description

Technical Field

[0001] The utility model relates to the technical field of dynamic balance detection, in particular to a dynamic balance correction device. Background Art

[0002] For rotating workpieces that perform rotational motion, due to uneven material or defects in the blank, errors caused during processing and assembly, the centrifugal inertia forces generated by each tiny particle on the rotating body cannot offset each other when it rotates. The centrifugal inertia forces act on the machine and its foundation through the bearings, causing vibration, generating noise, accelerating bearing wear, shortening the life of the machine, and in severe cases, causing destructive accidents.

[0003] Therefore, the rotating workpiece must be balanced to achieve the allowable balancing accuracy level or to reduce the resulting mechanical vibration amplitude to within the allowable range. The current dynamic balancing correction method is to remove or add mass to the surface of the rotating body based on the dynamic balancing test results to achieve the dynamic balancing correction effect. For workpieces that need to be drilled with ear holes in the circumferential direction, the formation of ear holes and balancing holes is mostly performed through independent processes, affecting the overall rhythm of workpiece production.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0045] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0046] The dynamic balance correction device provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0047] Example 1

[0048] like Figures 1 to 11 As shown, an embodiment of the present application provides a dynamic balancing correction device, including a workbench 100, a chuck 400, a drilling execution assembly 800, and a rotation drive assembly 900. The chuck 400 is rotatably connected to the workbench 100 and is used to position a workpiece. The rotation drive assembly 900 is used to drive the chuck 400 to rotate relative to the workbench 100. Two drilling execution assemblies 800 are provided on the workbench 100 and can move in the X, Y, and Z axes respectively.

[0049] Among them, the workbench 100 is also provided with a dynamic balancing detection unit 200 coupled with the chuck 400 and capable of detecting the dynamic balancing information of the workpiece positioned on the chuck 400. One drilling execution component 800 is used to drill ear holes on the workpiece positioned on the chuck 400, and the other drilling execution component 800 is used to drill balancing holes on the workpiece positioned on the chuck 400.

[0050] When the workpiece is to be processed, it is first positioned and installed on the chuck 400, and the rotary drive component 900 drives the chuck 400 to rotate to a predetermined position. One of the drilling execution components 800 moves to a predetermined position in the X and Y axes, and moves in the Z axis to drill the ear hole of the workpiece. When the ear hole at this position is drilled, the rotary drive component 900 drives the chuck 400 to rotate a predetermined angle, and the drilling execution component 800 moves in the Z axis again to drill the ear hole of the workpiece. Through the cooperation of the drilling execution component 800 and the rotary drive component 900, the ear hole drilling of the workpiece positioned on the chuck 400 in the circumferential direction can be achieved.

[0051] When the ear holes of the positioning workpiece on the chuck 400 are drilled, the rotary drive component 900 drives the chuck 400 to drive the positioning workpiece to rotate. At this time, the dynamic balance detection unit 200 can obtain the dynamic balance information of the positioning workpiece on the chuck 400. When the dynamic balance information is obtained, the rotary drive component 900 cooperates with another drilling execution component 800 to drill balance holes on the positioning workpiece on the chuck 400. Through the parameters of the balance holes of the positioning workpiece on the chuck 400 (such as hole diameter, hole depth, number, distribution position, etc.), the dynamic balance correction of the positioning workpiece on the chuck 400 can be achieved.

[0052] In an embodiment of the present application, the above-mentioned dynamic balancing correction device is used to combine the circumferential ear hole drilling of the workpiece with the dynamic balancing detection and the balancing hole drilling. On the one hand, it can avoid repeated tooling when multiple processing processes are executed, thereby improving the overall processing efficiency of the workpiece. On the other hand, through one-time positioning, it can ensure the benchmark consistency of the ear hole drilling and dynamic balancing correction process, making the dynamic balancing detection result more accurate, thereby improving the dynamic balancing correction quality of the workpiece.

[0053] In a preferred embodiment, Figures 1 to 3 As shown, a main shaft 300 is rotatably disposed on the workbench 100 , and a chuck 400 is fixedly disposed on the main shaft 300 .

[0054] The detection end of the dynamic balance detection unit 200 is coupled to an end of the spindle 300 away from the chuck 400 .

[0055] In a preferred embodiment, Figure 1 , Figure 2 As shown, the rotation drive assembly 900 includes a detection motor 910 fixedly mounted on the workbench 100, an adjustment main gear 920 is fixedly mounted on the power output end of the detection motor 910, an adjustment slave gear 940 is fixedly mounted on the main shaft 300, and an adjustment transmission belt 930 is wound between the adjustment main gear 920 and the adjustment slave gear 940.

[0056] It is understandable that when the detection motor 910 drives the adjustment main gear 920 to rotate, the adjustment transmission belt 930 can be used to drive the adjustment slave gear 940 to rotate, thereby realizing the rotation control of the main shaft 300 and the chuck 400 .

[0057] It is understandable that the setting form of the rotation drive assembly 900 is not limited to the above one. For example, a gear transmission structure or a worm gear transmission structure can also be used to realize the rotation drive of the main shaft 300, as long as the rotation control of the chuck 400 can be achieved, which is not elaborated here.

[0058] In a preferred embodiment, Figures 1 to 5As shown, an X-direction drive mechanism 710 is fixedly provided on the workbench 100 , a Y-direction drive mechanism 720 is fixedly connected to the action execution end of the X-direction drive mechanism 710 , and two Z-direction drive mechanisms 730 are fixedly connected to the power execution end of the Y-direction drive mechanism 720 .

[0059] The two drilling execution assemblies 800 are respectively fixedly disposed on the power execution ends of the two Z-direction driving mechanisms 730 .

[0060] The X-axis driving mechanism 710 can drive the Y-axis driving mechanism 720, the Z-axis driving mechanism 730, and the drilling execution component 800 to move upward in the X-axis. The Y-axis driving mechanism 720 can drive the Z-axis driving mechanism 730 and the drilling execution component 800 to move upward in the Y-axis. The Z-axis driving mechanism 730 can drive the drilling execution component 800 at the corresponding position to move in the Z-axis.

[0061] It can be understood that the movement drive form of the drilling execution component 800 in the X, Y, and Z axes is not limited to the above-mentioned one. For example, the Y-axis drive mechanism 720 can be fixedly set on the workbench 100, and the X-axis drive mechanism 710 can be fixedly set on the action execution end of the Y-axis drive mechanism 720. At this time, the adjustment of the drilling execution component 800 to any position on the horizontal plane can also be achieved through the linkage control of the X-axis drive mechanism 710 and the Y-axis drive mechanism 720. As long as the movement control of the drilling execution component 800 within the predetermined coordinate range on the X, Y, and Z coordinate systems can be guaranteed, it will not be elaborated here.

[0062] In a preferred embodiment, Figures 1 to 3 As shown, the X-axis driving mechanism 710 includes a first driving motor 711 and a first mounting bracket 715 fixedly arranged on the workbench 100. A first screw 712 rotatably connected to the first mounting bracket 715 is fixedly connected to the power output end of the first driving motor 711, and a first slide 714 is threadedly connected to the first screw 712.

[0063] The Y-axis driving mechanism 720 is fixedly disposed on the first slide 714 .

[0064] In a preferred embodiment, Figures 1 to 3 As shown, the X-axis driving mechanism 710 further includes at least one first guide rail 713 fixedly disposed on the workbench 100 and parallel to the first screw rod 712 , and the first slide 714 is slidably connected to the first guide rail 713 .

[0065] It can be understood that when the first screw 712 rotates, the first slide 714 can be driven by the thread to move axially along the first screw 712. At this time, the first guide rail 713 can slide and guide the first slide 714, thereby improving the stability of the drilling execution component 800 when moving in the X-axis direction.

[0066] In a preferred embodiment, Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the Y-axis driving mechanism 720 includes a transverse shift seat 721 fixedly arranged on the first slide 714, on which a second driving motor 722 and a second mounting bracket 725 are fixedly arranged, and a second screw rod 723 rotatably connected to the second mounting bracket 725 is fixedly connected to the power output end of the second driving motor 722, and a first screw block 724 is threadedly connected to the second screw rod 723.

[0067] The axial direction of the second screw rod 723 is perpendicular to the axial direction of the first screw rod 712 on a horizontal plane, and the Z-direction driving mechanism 730 is fixedly disposed on the first screw block 724 .

[0068] In a preferred embodiment, Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the Z-axis driving mechanism 730 includes a second slide 731 fixedly arranged on the first screw block 724, a longitudinal bracket 732 is fixedly arranged on the second slide 731, two third driving motors 733 are fixedly arranged on the longitudinal bracket 732, and third screws 734 rotatably connected to the longitudinal bracket 732 are respectively fixedly connected to the power output ends of the two third driving motors 733, and a second screw block 735 is threadedly connected to the third screw 734.

[0069] The axial directions of the two third screw rods 734 are respectively perpendicular to the horizontal planes where the axial directions of the second screw rod 723 and the first screw rod 712 are located, and the two drilling execution assemblies 800 are respectively fixedly disposed on the two second screw blocks 735 .

[0070] In a preferred embodiment, Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the Y-axis driving mechanism 720 also includes at least one second guide rail 726 fixedly disposed on the transverse shift seat 721 and parallel to the second screw rod 723 , and the second slide 731 is slidably connected to the second guide rail 726 .

[0071] It can be understood that when the second drive motor 722 rotates, it can drive the first screw block 724 to move axially along the second screw rod 723 through the thread. At this time, the second guide rail 726 can slide and guide the second slide 731, thereby improving the stability of the drilling execution component 800 when moving upward on the Y axis.

[0072] In a preferred embodiment, Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, the drilling execution component 800 includes a third slide 850 fixedly set on the second screw block 735, a drive box 820 is fixedly provided on the third slide 850, a drilling motor 810 is fixedly provided on the drive box 820, and a drilling main gear 860 is fixedly connected to the power output end of the drilling motor 810.

[0073] The drilling execution component 800 also includes a drilling shaft 830 which is rotatably connected to the driving box 820 and parallel to the third screw 734. A drill bit 840 is fixedly provided at one end of the drilling shaft 830 close to the chuck 400, and a drilling slave gear 870 is fixedly provided at the other end away from the chuck 400. A drilling transmission belt 880 is wound between the drilling slave gear 870 and the drilling main gear 860.

[0074] It is understandable that when the drilling motor 810 drives the drilling main gear 860 to rotate, it can drive the drilling slave gear 870 and the drilling shaft 830 to rotate through the drilling transmission belt 880, thereby realizing the rotational drilling control of the drill bit 840.

[0075] It is understandable that the setting form of the drilling execution component 800 is not limited to the above-mentioned one. For example, a gear transmission structure or a worm gear transmission structure can also be used to realize the rotational drive of the drill bit 840. As long as the rotation control of the drill bit 840 can be achieved, it will not be elaborated here.

[0076] In a preferred embodiment, Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, a cavity is provided in the driving box 820 , and the drilling main gear 860 , the drilling slave gear 870 , and the drilling transmission belt 880 are located in the cavity of the driving box 820 .

[0077] In a preferred embodiment, Figure 1 , Figure 2 , Figures 4 to 6 As shown, the Z-axis driving mechanism 730 further includes at least one third guide rail 736 fixedly disposed on the longitudinal bracket 732 and respectively disposed corresponding to the two third screw rods 734 .

[0078] The third guide rail 736 is parallel to the third screw rod 734 , and the two third slides 850 are slidably connected to the third guide rails 736 at positions corresponding to the two third screw rods 734 .

[0079] It can be understood that when the third drive motor 733 rotates, it can drive the second screw block 735 to move axially along the third screw rod 734 through the thread. At this time, the third guide rail 736 can slide and guide the third slide 850 at the corresponding position, thereby improving the stability of the drilling execution component 800 when moving upward in the Z axis.

[0080] In a preferred embodiment, Figure 1 , Figure 2 , Figure 6 As shown, the drilling execution assembly 800 further includes a chip cleaning assembly that is disposed on the drilling execution assembly 800 and is used to clean drilling debris.

[0081] In a preferred embodiment, Figure 1 , Figure 2 , Figure 6 As shown, the chip cleaning assembly includes a mounting plate 891 fixedly connected to the third slide 850 , a slide rod 896 elastically sliding in the vertical direction is provided on the mounting plate 891 , and a chip suction box 893 slidably connected to the drill shaft 830 is fixedly connected to the slide rod 896 .

[0082] A chip suction chamber is provided in the chip suction box 893 , and a discharge pipe 895 and a suction head 894 which are connected to the chip suction chamber are fixedly provided on the chip suction box 893 . The discharge pipe 895 is connected to a fan at one end away from the chip suction box 893 , and the suction head 894 is sleeved on the drill bit 840 .

[0083] It can be understood that when the drilling execution component 800 moves in the Z-axis direction to perform drilling through the drill bit 840, the external fan is started, thereby absorbing and cleaning the drilling waste chips through the exhaust pipe 895, the chip suction chamber, and the suction head 894. When the drilling execution component 800 moves upward in the Z-axis until the suction head 894 collides with the workpiece processing plane, the chip suction box 893 and the slide rod 896 will move relative to the third slide 850 to the side away from the drill bit 840 under the action of the resistance force exerted on the suction head 894, thereby making way for the drilling feed of the drill bit 840 and ensuring that the waste chips are always kept clean during the drilling operation.

[0084] In a preferred embodiment, Figure 1 , Figure 2 , Figure 6 As shown, a sleeve 892 is passed through and fixedly provided on the mounting plate 891 , and a slide rod 896 is slidably provided in the sleeve 892 and is sleeved with a return spring 897 .

[0085] One end of the return spring 897 abuts against the end of the sleeve 892 close to the chuck 400 , and the other end abuts against the end surface of the chip suction box 893 away from the chuck 400 .

[0086] It is understandable that the elastic sliding setting form of the slide rod 896 on the mounting plate 891 is not limited to the above-mentioned one, as long as it can realize the automatic resetting of the chip suction box 893 and the suction head 894, which will not be elaborated here.

[0087] In a preferred embodiment, Figures 1 to 3 , Figure 7 As shown, a positioning assembly 600 for positioning the outer ear of the positioning workpiece on the chuck 400 is fixedly provided on the workbench 100 .

[0088] In a preferred embodiment, Figures 1 to 3 , Figure 7 As shown, the positioning assembly 600 includes a base 610 fixedly mounted on the workbench 100, a transition frame 620 fixedly mounted on the base 610, a positioning cylinder 640 fixedly mounted on the transition frame 620, a follower plate 650 fixedly mounted on the telescopic end of the positioning cylinder 640, and a butt 670 capable of abutting against the outer ear of the workpiece fixedly mounted on the follower plate 650.

[0089] It is understandable that when drilling the ear hole of the workpiece positioned on the chuck 400, the drilling position is specifically the outer ear position of the workpiece. In order to ensure the accuracy of the ear hole drilling position, the outer ear of the workpiece needs to be initially positioned before the ear hole drilling. The conventional positioning means is to set a detachable abutment on the chuck 400, but since the present embodiment also includes a subsequent dynamic balance test of the workpiece, in order to ensure the dynamic balance of the chuck 400 itself, after the abutment is installed on the chuck 400, it is also necessary to manually set a counterweight at a symmetrical position on the central axis of the chuck 400, so as to achieve the weight balance of the chuck 400 itself and reduce its influence on the dynamic balance test of the workpiece.

[0090] In an embodiment of the present application, the above-mentioned dynamic balancing correction device is adopted. When the ear hole of the workpiece is drilled, the positioning cylinder 640 is extended and retracted to drive the abutment 670 to move and abut against the outer ear of the workpiece, that is, a suspended abutment positioning method is adopted to achieve the initial positioning of the outer ear of the workpiece. When the workpiece is subjected to dynamic balancing detection, the abutment 670 can be automatically reset so that it does not affect the center of gravity of the chuck 400 itself. On the one hand, the weight adjustment process of the chuck 400 is omitted, thereby improving the overall processing efficiency of the workpiece. On the other hand, the dynamic balancing detection accuracy of the workpiece can be improved.

[0091] In a preferred embodiment, Figures 1 to 3 , Figure 7As shown, a slide seat 630 is fixedly provided on the transition frame 620 , and a guide rod 660 slidably connected to the transition frame 620 and the slide seat 630 is fixedly provided on the driven plate 650 .

[0092] It is understandable that when the positioning cylinder 640 drives the driven plate 650 to move, the sliding guide of the guide rod 660, the transition frame 620 and the slide seat 630 can improve the smoothness of the movement process of the butt 670.

[0093] Example 2

[0094] like Figures 1 to 11 As shown, an embodiment of the present application provides a circumferential drilling device, including a workbench 100, a chuck 400, a drilling execution assembly 800, and a rotation drive assembly 900. The chuck 400 is rotatably connected to the workbench 100, and the rotation drive assembly 900 is used to drive the chuck 400 to rotate relative to the workbench 100. The drilling execution assembly 800 is arranged on the workbench 100 and can move in the X, Y, and Z axes.

[0095] A plurality of locking assemblies 410 are fixedly connected and arranged in a circular array on the chuck 400 about its own rotation axis, and a limiting unit 500 for limiting the relative angle between the chuck 400 and the workbench 100 is also fixedly arranged on the workbench 100 .

[0096] When the workpiece is to be processed, the workpiece is first positioned and installed on the chuck 400 through the locking assembly 410, the rotary drive assembly 900 drives the chuck 400 to rotate to a predetermined position, the drilling execution assembly 800 moves to a predetermined position in the X and Y axes, and moves in the Z axis to perform drilling on the workpiece. At this time, the limit unit 500 is started to limit the rotation of the chuck 400. When the hole at this position is drilled, the limit unit 500 releases the limit on the chuck 400, the rotary drive assembly 900 drives the chuck 400 to rotate a predetermined angle, the drilling execution assembly 800 moves in the Z axis again to perform drilling on the workpiece, and the limit unit 500 limits the rotation of the chuck 400 again. Through the cooperation of the drilling execution assembly 800, the rotary drive assembly 900 and the limit unit 500, multi-hole drilling of the workpiece positioned on the chuck 400 in the circumferential direction can be achieved.

[0097] In an embodiment of the present application, the above-mentioned circumferential drilling device is adopted, and when the drilling execution component 800 moves in the Z-axis direction to perform drilling of the workpiece, the rotation of the chuck 400 is limited by the limiting unit 500, that is, during the drilling process, the workpiece and the workbench 100 are kept relatively still, thereby reducing the influence of the vibration when the device performs the drilling action on the positioning accuracy of the workpiece, thereby improving the circumferential drilling positioning accuracy of the workpiece and ensuring the overall quality of the workpiece.

[0098] In a preferred embodiment, Figures 1 to 3As shown, a main shaft 300 is rotatably disposed on the workbench 100 , and a chuck 400 is fixedly disposed on the main shaft 300 .

[0099] The rotating drive assembly 900 includes a detection motor 910 fixedly mounted on the workbench 100, an adjustment main gear 920 is fixedly mounted on the power output end of the detection motor 910, an adjustment slave gear 940 is fixedly mounted on the main shaft 300, and an adjustment transmission belt 930 is wound between the adjustment main gear 920 and the adjustment slave gear 940.

[0100] It is understandable that when the detection motor 910 drives the adjustment main gear 920 to rotate, the adjustment transmission belt 930 can be used to drive the adjustment slave gear 940 to rotate, thereby realizing the rotation control of the main shaft 300 and the chuck 400 .

[0101] It is understandable that the setting form of the rotation drive assembly 900 is not limited to the above one. For example, a gear transmission structure or a worm gear transmission structure can also be used to realize the rotation drive of the main shaft 300, as long as the rotation control of the chuck 400 can be achieved, which is not elaborated here.

[0102] In a preferred embodiment, Figures 1 to 5 As shown, an X-direction driving mechanism 710 is fixedly provided on the workbench 100 , a Y-direction driving mechanism 720 is fixedly connected to the action execution end of the X-direction driving mechanism 710 , and a Z-direction driving mechanism 730 is fixedly connected to the power execution end of the Y-direction driving mechanism 720 .

[0103] The drilling execution assembly 800 is fixedly arranged on the power execution end of the Z-direction driving mechanism 730 .

[0104] The X-axis driving mechanism 710 can drive the Y-axis driving mechanism 720, the Z-axis driving mechanism 730, and the drilling execution component 800 to move upward in the X-axis. The Y-axis driving mechanism 720 can drive the Z-axis driving mechanism 730 and the drilling execution component 800 to move upward in the Y-axis. The Z-axis driving mechanism 730 can drive the drilling execution component 800 to move upward in the Z-axis.

[0105] It can be understood that the movement drive form of the drilling execution component 800 in the X, Y, and Z axes is not limited to the above-mentioned one. For example, the Y-axis drive mechanism 720 can be fixedly set on the workbench 100, and the X-axis drive mechanism 710 can be fixedly set on the action execution end of the Y-axis drive mechanism 720. At this time, the adjustment of the drilling execution component 800 to any position on the horizontal plane can also be achieved through the linkage control of the X-axis drive mechanism 710 and the Y-axis drive mechanism 720. As long as the movement control of the drilling execution component 800 within the predetermined coordinate range on the X, Y, and Z coordinate systems can be guaranteed, it will not be elaborated here.

[0106] In a preferred embodiment, Figures 1 to 3 As shown, the X-axis driving mechanism 710 includes a first driving motor 711 and a first mounting bracket 715 fixedly arranged on the workbench 100. A first screw 712 rotatably connected to the first mounting bracket 715 is fixedly connected to the power output end of the first driving motor 711, and a first slide 714 is threadedly connected to the first screw 712.

[0107] The Y-axis driving mechanism 720 is fixedly disposed on the first slide 714 .

[0108] In a preferred embodiment, Figures 1 to 3 As shown, the X-axis driving mechanism 710 further includes at least one first guide rail 713 fixedly disposed on the workbench 100 and parallel to the first screw rod 712 , and the first slide 714 is slidably connected to the first guide rail 713 .

[0109] It can be understood that when the first screw 712 rotates, the first slide 714 can be driven by the thread to move axially along the first screw 712. At this time, the first guide rail 713 can slide and guide the first slide 714, thereby improving the stability of the drilling execution component 800 when moving in the X-axis direction.

[0110] In a preferred embodiment, Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the Y-axis driving mechanism 720 includes a transverse shift seat 721 fixedly arranged on the first slide 714, on which a second driving motor 722 and a second mounting bracket 725 are fixedly arranged, and a second screw rod 723 rotatably connected to the second mounting bracket 725 is fixedly connected to the power output end of the second driving motor 722, and a first screw block 724 is threadedly connected to the second screw rod 723.

[0111] The axial direction of the second screw rod 723 is perpendicular to the axial direction of the first screw rod 712 on a horizontal plane, and the Z-direction driving mechanism 730 is fixedly disposed on the first screw block 724 .

[0112] In a preferred embodiment, Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the Z-axis driving mechanism 730 includes a second slide 731 fixedly arranged on the first screw block 724, a longitudinal bracket 732 is fixedly arranged on the second slide 731, a third driving motor 733 is fixedly arranged on the longitudinal bracket 732, a third screw 734 rotatably connected to the longitudinal bracket 732 is fixedly connected to the power output end of the third driving motor 733, and a second screw block 735 is threadedly connected to the third screw 734.

[0113] The axial direction of the third screw rod 734 is perpendicular to the horizontal plane where the axial directions of the second screw rod 723 and the first screw rod 712 are located, and the drilling execution assembly 800 is fixedly disposed on the second screw block 735 .

[0114] In a preferred embodiment, Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the Y-axis driving mechanism 720 also includes at least one second guide rail 726 fixedly disposed on the transverse shift seat 721 and parallel to the second screw rod 723 , and the second slide 731 is slidably connected to the second guide rail 726 .

[0115] It can be understood that when the second drive motor 722 rotates, it can drive the first screw block 724 to move axially along the second screw rod 723 through the thread. At this time, the second guide rail 726 can slide and guide the second slide 731, thereby improving the stability of the drilling execution component 800 when moving upward on the Y axis.

[0116] In a preferred embodiment, Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, the drilling execution component 800 includes a third slide 850 fixedly set on the second screw block 735, a drive box 820 is fixedly provided on the third slide 850, a drilling motor 810 is fixedly provided on the drive box 820, and a drilling main gear 860 is fixedly connected to the power output end of the drilling motor 810.

[0117] The drilling execution component 800 also includes a drilling shaft 830 which is rotatably connected to the driving box 820 and parallel to the third screw 734. A drill bit 840 is fixedly provided at one end of the drilling shaft 830 close to the chuck 400, and a drilling slave gear 870 is fixedly provided at the other end away from the chuck 400. A drilling transmission belt 880 is wound between the drilling slave gear 870 and the drilling main gear 860.

[0118] It is understandable that when the drilling motor 810 drives the drilling main gear 860 to rotate, it can drive the drilling slave gear 870 and the drilling shaft 830 to rotate through the drilling transmission belt 880, thereby realizing the rotational drilling control of the drill bit 840.

[0119] It is understandable that the setting form of the drilling execution component 800 is not limited to the above-mentioned one. For example, a gear transmission structure or a worm gear transmission structure can also be used to realize the rotational drive of the drill bit 840. As long as the rotation control of the drill bit 840 can be achieved, it will not be elaborated here.

[0120] In a preferred embodiment, Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, a cavity is provided in the driving box 820 , and the drilling main gear 860 , the drilling slave gear 870 , and the drilling transmission belt 880 are located in the cavity of the driving box 820 .

[0121] In a preferred embodiment, Figure 1 , Figure 2 , Figures 4 to 6 As shown, the Z-axis driving mechanism 730 also includes at least one third guide rail 736 fixedly disposed on the longitudinal bracket 732 and parallel to the third screw rod 734 , and the third slide 850 is slidably connected to the third guide rail 736 .

[0122] It can be understood that when the third drive motor 733 rotates, it can drive the second screw block 735 to move axially along the third screw rod 734 through the thread. At this time, the third guide rail 736 can slide and guide the third slide 850 at the corresponding position, thereby improving the stability of the drilling execution component 800 when moving upward in the Z axis.

[0123] In a preferred embodiment, Figures 1 to 3 , Figures 8 to 10 As shown, the limiting unit 500 includes at least one limiting cylinder 510 fixedly mounted on the workbench 100 and located on the side of the chuck 400 away from the drilling actuator 800, a cone 520 is fixedly connected to the telescopic end of the limiting cylinder 510, and an insert rod 530 is fixedly connected to the end of the cone 520 away from the limiting cylinder 510.

[0124] Among them, the chuck 400 is provided with a plurality of limiting through holes 430 which can be plugged with the insertion rod 530 in a circular array about its own rotation axis, and the cone 520 is cone-shaped. From the limiting cylinder 510 to the chuck 400, the diameter of the cone 520 gradually decreases until it is the same as the diameter of the insertion rod 530.

[0125] In an embodiment of the present application, the above-mentioned circumferential drilling device is adopted. When the chuck 400 is rotated to the drilling position of the workpiece, the limiting cylinder 510 can drive the cone 520 and the insertion rod 530 to move toward the side close to the chuck 400. The insertion rod 530 is inserted in the locking assembly 410 on the chuck 400, thereby limiting the rotation of the chuck 400 relative to the workbench 100. At the same time, the cone 520 has a cone-shaped structure. When the insertion rod 530 is connected with the locking assembly 410, the cone 520 can use its own outer cone surface to contact the inner wall of the locking assembly 410 to realize automatic centering of the insertion rod 530 relative to the locking assembly 410, thereby improving the position accuracy of the workpiece during drilling, and further improving the vibration resistance of the chuck 400 after limiting.

[0126] In a preferred embodiment, Figure 1 , Figure 3 , Fig. 9, Fig.10 As shown, the chuck 400 is provided with a plurality of mounting grooves 411 in a circular array about its own rotation axis, and the locking assembly 410 is fixedly disposed in the mounting groove 411 .

[0127] Among them, there are multiple locking assemblies 410, and the multiple locking assemblies 410 are evenly distributed in a circular array about the rotation axis of the chuck 400. The limiting through hole 430 is set on the end face of the chuck 400 away from the drilling execution assembly 800 and penetrates the bottom wall of the installation groove 411.

[0128] In a preferred embodiment, Figure 1 , Figure 3 , Fig. 9 As shown, the locking assembly 410 includes a connecting plate 412 fixedly disposed in a mounting groove 411 , an adjusting plate 414 is fixedly disposed on the connecting plate 412 , and an adjusting bolt 415 is threadedly connected along the radial direction of the chuck 400 on the adjusting plate 414 .

[0129] A plurality of positioning holes 413 are provided on the connecting plate 412 in a radial linear array along the chuck 400. The locking assembly 410 also includes a limiting stopper 416, which has a U-shaped groove 417 extending therethrough. The limiting stopper 416 is bolted to the connecting plate 412 via the U-shaped groove 417 and the positioning holes 413.

[0130] The end of the adjusting bolt 415 away from the rotation axis of the chuck 400 can abut against the inner annular surface of the workpiece, and the end of the limiting stop block 416 close to the rotation axis of the chuck 400 can abut against the outer annular surface of the workpiece.

[0131] It can be understood that when the workpiece is placed on the chuck 400, the operator can rotate the adjusting bolt 415 so that the end of the adjusting bolt 415 away from the rotation axis of the chuck 400 abuts the inner annular surface of the workpiece, and the external support positioning of the inner annular surface of the workpiece can be achieved through multiple adjusting bolts 415. At the same time, the limit stop block 416 can be bolted through the positioning holes 413 at different positions, so as to adjust the annular array radius of the limit stop block 416 so that it abuts against the outer annular surface of the workpiece, and the inner support positioning of the outer annular surface of the workpiece can be achieved through multiple limit stop blocks 416.

[0132] It is understandable that the length direction of the U-shaped groove 417 is the radial direction of the chuck 400. The U-shaped groove 417 can improve its position adaptability with the positioning hole 413, thereby achieving stepless adjustment of the radius of the annular array of the limiting stop block 416.

[0133] In a preferred embodiment, Fig.10 , Fig.11 As shown, the locking assembly 410 includes a connection plate 412 fixedly disposed in a mounting groove 411 , and a plurality of positioning holes 413 are provided on the connection plate 412 in a radial linear array along the chuck 400 .

[0134] The locking assembly 410 further includes a limiting stopper 416 , which is provided with a through hole 418 . The limiting stopper 416 is bolted to the connecting plate 412 via the through hole 418 and the positioning hole 413 .

[0135] A first embedding groove 419 extending radially along the chuck 400 is provided on the end surface of the connecting plate 412 away from the workbench 100 , and a plurality of second embedding grooves 420 communicating with the first embedding groove 419 are also provided on the connecting plate 412 in a radial linear array with respect to the chuck 400 .

[0136] A first protrusion 421 that can be engaged with the first embedding groove 419 is fixedly provided on the end surface of the limiting stopper 416 close to the workbench 100 , and a second protrusion 422 that can be engaged with the second embedding groove 420 is also fixedly provided.

[0137] It can be understood that by embedding the second protrusion 422 of the limit stop block 416 in the second embedding groove 420 at different positions, the annular array radius of multiple limit stop blocks 416 can be adjusted, thereby achieving abutment positioning on the inner ring surface or outer ring surface of the workpiece. At the same time, after the limit stop block 416 and the connecting plate 412 are bolted together through the through hole 418 and the positioning hole 413, the positioning reliability of the workpiece can be further improved.
