DETAILED DESCRIPTION

[0027] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0028] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0029] like Figure 1 、 Figure 2 、 Figure 6 、 Figure 7The figure is a structural diagram of a rail drilling device provided by an embodiment of the present invention, comprising a workbench 1, wherein a plurality of supporting legs 11 are fixedly installed on the bottom wall of the workbench 1, a fixing frame 2 is fixedly installed in the middle of the workbench 1, and the fixing frame 2 is an inverted U-shaped structure. A hydraulic cylinder 3 is fixedly installed on the top wall of the fixing frame 2, and a drilling machine 4 is fixedly installed on the telescopic end of the hydraulic cylinder 3. A rail body 5 is placed above the workbench 1, and a sealing sleeve 41 is sleeved on the outer side of the drilling machine 4. A retaining ring 42 is rotatably installed on the bottom end of the sealing sleeve 41. A positioning mechanism 6 that cooperates with the rail body 5 is provided on the surface of the workbench 1, and the positioning mechanism 6 includes a bearing assembly 61 and a conveying assembly 62. The bearing assembly 61 is located on the surface of the workbench 1 and contacts with the rail body 5. The bearing assembly 61 is used to support and position the rail body 5 above the workbench 1, and the conveying assembly 62 is connected to the bearing assembly 61. The conveying component 62 controls the intermittent movement of the rail body 5 below the drilling machine 4 by cooperating with the bearing component 61. The surface of the drilling machine 4 is provided with a telescopic component 8 connected to the sealing sleeve 41. The telescopic component 8 is used to adjust the relative position of the sealing sleeve 41 and the drilling machine 4 in the vertical direction. The surface of the retaining ring 42 is provided with a cleaning mechanism 9. The cleaning mechanism 9 includes a cleaning plate 91, an adjustment component 92 and a collection component 93. The cleaning plate 91 is set as an arc structure. One end of the cleaning plate 91 is rotatably installed on the inner wall of the retaining ring 42. The adjustment component 92 is located on the surface of the retaining ring 42 and is connected to the cleaning plate 91. The adjustment component 92 is used to control the rotation of the retaining ring 42 at the bottom end of the sealing sleeve 41 and thereby adjust the relative position of the cleaning plate 91 and the retaining ring 42. The collecting component 93 is located on the surface of the workbench 1 and is directly below the drilling machine 4. The collecting component 93 is used to guide and discharge metal debris generated by drilling.

[0030] The telescopic assembly 8 positions the sealing sleeve 41 on the outside of the drilling machine 4. The sealing sleeve 41 and the retaining ring 42 are sleeved on the outside of the drilling machine 4. Initially, the adjustment assembly 92 controls the cleaning plate 91 to be located at the inner wall of the retaining ring 42. When the rail body 5 needs to be drilled, the rail body 5 is placed on the surface of the workbench 1. The bearing assembly 61 stably supports and positions the rail body 5, pushing the rail body 5 to move so that the position to be drilled moves to directly below the drilling machine 4. The hydraulic cylinder 3 pushes the drilling machine 4 to move vertically downward. The drilling machine 4 drives the sealing sleeve 41 and the retaining ring 42 to move downward synchronously. The bottom wall of the retaining ring 42 first contacts the surface of the rail body 5. The drilling machine 4 continues to move downward. The sealing sleeve 41 and the retaining ring 42 are stationary on the surface of the rail body 5. The telescopic assembly 8 controls the sealing sleeve 41 and the retaining ring 42 to move relatively upward on the outside of the drilling machine 4. The cleaning plate 91 will not interfere with the descending process of the drilling machine 4. The drilling machine 4 continues to move downward and then drills the rail body 5. During the drilling process, the sealing sleeve 41 and the retaining ring 42 cooperate with each other to fully block the metal debris generated by the drilling. All the metal debris falls on the surface of the rail body 5 and is in the inner cavity of the retaining ring 42.

[0031] After the drilling is completed, the hydraulic cylinder 3 controls the drilling machine 4 to move upward. When the drill rod at the bottom end of the drilling machine 4 moves above the cleaning plate 91, the telescopic component 8 controls the bottom wall of the retaining ring 42 to fit the surface of the rail body 5. The adjusting component 92 controls the retaining ring 42 to rotate at the bottom end of the sealing sleeve 41. The adjusting component 92 synchronously adjusts the position of the cleaning plate 91 so that the cleaning plate 91 moves away from the end of the inner wall of the retaining ring 42 to above the drilled circular hole. The retaining ring 42 drives the cleaning plate 91 to rotate synchronously. When rotating, the cleaning plate 91 pushes the metal debris on the surface of the rail body 5 to move synchronously, and further pushes the metal debris to move toward the circular hole drilled by the rail body 5. The metal debris can automatically pass through the circular hole on the surface of the rail body 5 and fall down. The collecting component 93 can automatically guide and collect the metal debris falling from the circular hole. After the metal debris on the surface of the rail body 5 is cleaned, the hydraulic cylinder 3 controls the drilling machine 4, the sealing sleeve 41 and the retaining ring 42 to move upward again. When the retaining ring 42 and the rail body 5 are separated from each other, the adjusting component 92 controls the retaining ring 42 to rotate in the opposite direction at the bottom of the sealing sleeve 41, thereby controlling the cleaning plate 91 to move as a whole to the outside of the drill rod at the bottom of the drilling machine 4. The conveying component 62 cooperates with the bearing component 61 to control the rail body 5 to move a certain distance on the surface of the workbench 1. When another position to be drilled on the surface of the rail body 5 moves to directly below the drilling machine 4, the hydraulic cylinder 3 pushes the drilling machine 4 to move downward again, and the surface of the rail body 5 can be drilled again. This cycle is repeated to drill multiple groups of parallel circular holes on the surface of the rail body 5.

[0032] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, as a preferred embodiment of the present invention, the bearing assembly 61 includes two groups of relatively distributed vertical plates 611 fixedly installed on the surface of the workbench 1, and multiple groups of horizontal columns 612 are rotatably installed between the two groups of vertical plates 611. The multiple groups of horizontal columns 612 are evenly spaced along the horizontal direction. Two groups of parallel distributed bearing plates 613 are fixedly installed on the surface of the horizontal columns 612, and the rail body 5 is placed on the surface of the multiple groups of bearing plates 613.

[0033] The two sets of vertical plates 611 support and position the multiple sets of horizontal columns 612, which in turn support and position the carrier plates 613. The rail body 5 is placed on the surfaces of the multiple sets of carrier plates 613. The multiple sets of carrier plates 613 are arranged in two rows, which can stably support and position the rail body 5 and push the rail body 5 to move horizontally above the workbench 1. After a single drilling operation is completed, the conveying assembly 62 controls the multiple sets of horizontal columns 612 to rotate between the two sets of vertical plates 611. The horizontal columns 612 drive the carrier plates 613 to rotate synchronously, and the carrier plates 613 can push the rail body 5 to move horizontally a certain distance above the workbench 1, thereby moving another location on the surface of the rail body 5 to be drilled to directly below the drilling machine 4.

[0034] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 As shown, as a preferred embodiment of the present invention, the conveying assembly 62 includes a guide gear disc 621 provided on the outside of the vertical plate 611 and one end of the horizontal column 612 extends. The side wall of the vertical plate 611 is slidably installed with a positioning bar 622 located on the outside of the guide gear disc 621 in the horizontal direction. The side wall of the positioning bar 622 is fixedly installed with a guide rack 623. The guide rack 623 is engaged with the guide gear disc 621. A connecting plate 624 is fixedly installed in the middle of the positioning bar 622. Two groups of side plates 625 are fixedly installed on the side walls of the vertical plate 611, which are respectively located on both sides of the connecting plate 624. The two groups of side plates 625 are rotatably installed with a threaded rod 626. The threaded rod 626 is threadedly connected to the connecting plate 624. One end of the threaded rod 626 extends to the outside of the side plate 625 and is connected to the first motor 627. The surface of the horizontal column 612 is provided with a limiting part 7 that cooperates with the guide gear plate 621. The limiting part 7 is used to control the unidirectional rotation of the guide gear plate 621 on the surface of the horizontal column 612.

[0035] When the position of the rail body 5 needs to be adjusted, the first motor 627 drives the threaded rod 626 to rotate, and the threaded rod 626 pushes the connecting plate 624 and the positioning bar 622 to move outside the vertical plate 611, and the positioning bar 622 drives the guide rack 623 to move synchronously, and the guide rack 623 engages with the guide sprocket 621 for transmission, which can drive the guide sprocket 621 and the cross column 612 to rotate synchronously. When the rail body 5 moves to the appropriate position, the first motor 627 drives the threaded rod 626 to rotate in the opposite direction, and the threaded rod 626 and the connecting plate 624 are spirally transmitted, thereby controlling the connecting plate 624 and the positioning bar 622 to move in the opposite direction to the original position outside the vertical plate 611. When the positioning bar 622 drives the guide rack 623 to move in the opposite direction synchronously, the limiting part 7 controls the guide sprocket 621 to rotate on the surface of the cross column 612. At this time, the cross column 612 and the supporting plate 613 remain relatively stationary between the two sets of vertical plates 611.

[0036] like Figure 3 、 Figure 4 、 Figure 5 As shown, as a preferred embodiment of the present invention, the limiting portion 7 includes a plurality of groups of annularly distributed receiving grooves 71 opened on the surface of the cross column 612, and a limiting block 72 is slidably installed in the receiving groove 71. One end of the limiting block 72 is set to a slope structure and extends to the outside of the receiving groove 71. An extrusion spring 74 is fixedly installed in the receiving groove 71, and the telescopic end of the extrusion spring 74 is connected to the limiting block 72. The guide gear disc 621 is sleeved on the surface of the cross column 612, and the inner side wall of the guide gear disc 621 is provided with a plurality of groups of limiting grooves 73 that cooperate with the limiting block 72.

[0037] The extrusion spring 74 applies a thrust to the limit block 72, and the limit block 72 is inserted into the limit groove 73 on the inner side of the guide gear disc 621. When the position of the rail body 5 needs to be adjusted, the guide rack 623 engages with the guide gear disc 621 for transmission. At this time, the limit block 72 is stuck in the limit groove 73. The limit block 72 and the limit groove 73 cooperate with each other to control the guide gear disc 621 and the cross column 612 to be connected as a whole, and the guide gear disc 621 drives the cross column 612 to rotate synchronously. When the rail body 5 moves to the appropriate position, the connecting plate 624 and the positioning bar 622 move in the opposite direction to the original position outside the vertical plate 611, and the positioning bar 622 drives the guide rack 623 to move in the opposite direction synchronously. The guide rack 623 engages with the guide sprocket 621 for transmission, thereby controlling the guide sprocket 621 to rotate in the opposite direction. When the guide sprocket 621 rotates in the opposite direction, it drives the limit groove 73 to rotate synchronously. The limit groove 73 applies a thrust to the limit block 72 and thus squeezes the limit block 72 as a whole into the receiving groove 71. The limit block 72 will not interfere with the reverse rotation process of the guide sprocket 621. At this time, the cross column 612 remains relatively stationary between the two sets of vertical plates 611, and the cross column 612 will not rotate synchronously with the guide sprocket 621.

[0038] like Figure 2 、 Figure 6 、 Figure 7 As shown, as a preferred embodiment of the present invention, the telescopic assembly 8 includes a top ring 81 fixedly mounted on the top wall of the drilling machine 4, and a plurality of groups of vertical rods 82 distributed in a ring are fixedly mounted on the bottom wall of the top ring 81. The plurality of vertical rods 82 are respectively connected to the sealing sleeve 41 for sliding along the vertical direction. The bottom ends of the vertical rods 82 extend to the top of the sealing sleeve 41 and are fixedly mounted with a bottom plate 83. The bottom wall of the top ring 81 is fixedly mounted with a telescopic spring 84, and the telescopic spring 84 is sleeved on the outside of the vertical rod 82. The telescopic end of the telescopic spring 84 is connected to the sealing sleeve 41.

[0039] The vertical rod 82 and the bottom plate 83 cooperate with each other to support and position the sealing sleeve 41 on the outside of the drilling machine 4. When the drilling machine 4, the sealing sleeve 41 and the retaining ring 42 move vertically downward, after the bottom end of the retaining ring 42 is in contact with the surface of the rail body 5, the vertical rod 82 moves vertically on the surface of the sealing sleeve 41, thereby controlling the drilling machine 4 to continue to move vertically downward. During the drilling process, the retaining ring 42 and the sealing sleeve 41 can fully block the metal debris generated by the drilling. After the drilling is completed, when the drilling machine 4 moves upward, the retaining ring 42 initially remains in contact with the surface of the rail body 5, thereby conveniently adjusting the relative position of the drilling machine 4 and the cleaning plate 91. After the drilling machine 4 moves as a whole to directly above the cleaning plate 91, the cleaning plate 91 can clean the metal debris.

[0040] like Figure 2 、 Figure 6 、 Figure 7 、 Figure 8 As shown, as a preferred embodiment of the present invention, the adjustment assembly 92 includes a gear ring 921 fixedly mounted on the outer wall of the retaining ring 42, a second motor 922 fixedly mounted on the surface of the sealing sleeve 41, a transmission gear disc 923 fixedly mounted on the output shaft of the second motor 922, the transmission gear disc 923 is meshed and connected with the gear ring 921, a positioning rope 924 is fixedly mounted on the inner wall of the retaining ring 42, and the end of the positioning rope 924 away from the retaining ring 42 is connected to the cleaning plate 91.

[0041] Initially, the cleaning plate 91 is located at the inner wall of the retaining ring 42. During drilling, the cleaning plate 91 does not interfere with the descent process of the drilling machine 4. When drilling is completed and the drilling machine 4 moves as a whole to directly above the cleaning plate 91, the second motor 922 drives the transmission gear disc 923 to rotate. The transmission gear disc 923 engages with the gear ring 921 for transmission, which can drive the retaining ring 42 to rotate at the bottom end of the sealing sleeve 41. The retaining ring 42 drives the cleaning plate 91 to rotate synchronously. During rotation, the positioning rope 924 further positions the cleaning plate 91. The end of the cleaning plate 91 away from the retaining ring 42 moves to directly above the circular hole drilled on the surface of the rail body 5. During rotation, the cleaning plate 91 pushes the metal debris on the surface of the rail body 5 to move synchronously, and further pushes the metal debris toward the circular hole drilled in the rail body 5. The metal debris can automatically pass through the circular hole on the surface of the rail body 5 and fall down. After the metal debris is cleaned, the second motor 922 drives the transmission gear disc 923 to rotate in the opposite direction. The transmission gear disc 923 engages with the gear ring 921 for transmission, which can drive the retaining ring 42 to rotate in the opposite direction synchronously at the bottom end of the sealing sleeve 41. When the retaining ring 42 rotates in the opposite direction, the cleaning plate 91 is controlled to rotate toward the inner wall of the retaining ring 42. After the cleaning plate 91 moves as a whole to the outside of the drilling machine 4, the next drilling process can be carried out, and the cleaning plate 91 will not interfere with the drilling machine 4.

[0042] like Figure 2 、 Figure 9 As shown, as a preferred embodiment of the present invention, the collecting assembly 93 includes a guide tube 931 slidably installed on the surface of the workbench 1 along the vertical direction, the two ends of the guide tube 931 are through, a fixing ring 932 is fixedly installed on the surface of the guide tube 931, and a control spring 933 is fixedly installed on the surface of the workbench 1, and the control spring 933 surrounds the outside of the guide tube 931 and is connected to the fixing ring 932.

[0043] The control spring 933 applies a vertical upward thrust to the fixing ring 932 and the guide tube 931. The top of the guide tube 931 fits against the bottom wall of the rail body 5. The metal debris falls through the circular hole on the surface of the rail body 5 and further falls into the guide tube 931. The guide tube 931 can guide the metal debris.

[0044] like Figure 1 、 Figure 3 As shown, as a preferred embodiment of the present invention, two groups of limiting plates 10 are fixedly installed on the surface of the horizontal column 612, and the two groups of limiting plates 10 are respectively located on both sides of the two groups of supporting plates 613.

[0045] The limiting plate 10 is located outside the rail body 5 , and the limiting plate 10 cooperates with the supporting plate 613 to effectively prevent the rail body 5 from deflecting during movement.

[0046] like Figure 8As shown, as a preferred embodiment of the present invention, the bottom wall of the retaining ring 42 is provided with multiple groups of positioning holes 12 , and balls 13 are placed in the positioning holes 12 , and the bottom ends of the balls 13 extend to the outside of the positioning holes 12 .

[0047] like Figure 8 As shown, as a preferred embodiment of the present invention, the bottom wall of the sealing sleeve 41 is provided with an annular positioning groove 14 , and a positioning ring 15 is rotatably installed in the positioning groove 14 . The positioning ring 15 extends to the outside of the positioning groove 14 and is connected to the retaining ring 42 .

[0048] The working principle of the present invention is as follows: two groups of vertical plates 611 support and position multiple groups of horizontal columns 612, and the horizontal columns 612 support and position the carrier plates 613. The rail body 5 is placed on the surface of the multiple groups of carrier plates 613. The multiple groups of carrier plates 613 are arranged in two rows, which can stably support and position the rail body 5, push the rail body 5 to move so that the position to be drilled moves to directly below the drilling machine 4. The hydraulic cylinder 3 pushes the drilling machine 4 to move vertically downward, and the drilling machine 4 drives the sealing sleeve 41 and the retaining ring 42 to move downward synchronously. When the bottom end of the retaining ring 42 is in contact with the surface of the rail body 5, the vertical rod 82 moves vertically on the surface of the sealing sleeve 41, thereby controlling the drilling machine 4 to continue to move vertically downward. During the drilling process, the retaining ring 42 and the sealing sleeve 41 can fully block the metal debris generated by drilling. All the metal debris falls on the surface of the rail body 5 and is in the inner cavity of the retaining ring 42.

[0049] After the drilling is completed, the hydraulic cylinder 3 controls the drilling machine 4 to move upward, and the retaining ring 42 initially maintains a state of contact with the surface of the rail body 5, so that the relative position of the drilling machine 4 and the cleaning plate 91 can be easily adjusted. After the drilling machine 4 moves as a whole to just above the cleaning plate 91, the second motor 922 drives the transmission gear plate 923 to rotate, and the transmission gear plate 923 engages with the gear ring 921 for transmission, which can drive the retaining ring 42 to rotate at the bottom end of the sealing sleeve 41, and the retaining ring 42 drives the cleaning plate 91 to rotate synchronously. During rotation, the positioning rope 924 further positions the cleaning plate 91, and the end of the cleaning plate 91 away from the retaining ring 42 moves to just above the circular hole drilled on the surface of the rail body 5. When the cleaning plate 91 rotates, it pushes the metal debris on the surface of the rail body 5 to move synchronously, and further pushes the metal debris to move toward the circular hole drilled by the rail body 5, and the metal debris can automatically pass through the circular hole on the surface of the rail body 5 and fall down. After the metal debris is cleaned, the second motor 922 drives the transmission gear disc 923 to rotate in the opposite direction. The transmission gear disc 923 engages with the gear ring 921 for transmission, which can drive the retaining ring 42 to rotate in the opposite direction synchronously at the bottom end of the sealing sleeve 41. When the retaining ring 42 rotates in the opposite direction, the cleaning plate 91 is controlled to rotate toward the inner wall of the retaining ring 42. After the cleaning plate 91 moves as a whole to the outside of the drilling machine 4, the hydraulic cylinder 3 controls the drilling machine 4, the sealing sleeve 41 and the retaining ring 42 to move upward again.

[0050] After the retaining ring 42 and the rail body 5 are separated from each other, the first motor 627 drives the threaded rod 626 to rotate, and the threaded rod 626 pushes the connecting plate 624 and the positioning bar 622 to move outside the vertical plate 611. The positioning bar 622 drives the guide rack 623 to move synchronously. The guide rack 623 engages with the guide gear disc 621 for transmission, which can drive the guide gear disc 621 and the crossbar 612 to rotate synchronously. The crossbar 612 drives the supporting plate 613 to rotate synchronously. The supporting plate 613 can push the rail body 5 to translate a certain distance above the workbench 1, thereby moving another position to be drilled on the surface of the rail body 5 to be directly below the drilling machine 4. The hydraulic cylinder 3 pushes the drilling machine 4 to move downward again, and the surface of the rail body 5 can be drilled again. This cycle is repeated, and multiple groups of parallel circular holes can be drilled on the surface of the rail body 5.

Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
