An arch plate 6 is fixedly arranged on the machining table 1. It further includes:

[0083] A moving mechanism, which is arranged on the arch plate 6 and is electrically connected to the control device 2;

[0084] The moving mechanism includes:

[0085] A fixed block 7, which is fixedly arranged on the arch plate 6, and a longitudinal sliding groove 8 penetrating the arch plate 6 is formed on the fixed block 7;

[0086] A first motor 9, which is fixedly arranged on the fixed block 7 and is electrically connected to the control device 2;

[0087] A first screw rod 10, which is rotatably arranged on the fixed block 7, and one end of the first screw rod 10 close to the first motor 9 is fixedly connected to the output end of the first motor 9;

[0088] A first slider 11, which is slidably arranged on the fixed block 7 and is threadedly connected to the first screw rod 10. A receiving groove 12 is formed on the surface of the first slider 11 close to the machining table 1;

[0089] A first hydraulic push rod 13, which is arranged in the receiving groove 12 and is fixedly connected to the first slider 11. The first hydraulic push rod 13 is electrically connected to the control device 2;

[0090] During operation, the control device 2 controls the electric telescopic shaft to start, so that the rotation of the electric telescopic shaft is used to transport the plate until the area of the plate to be processed is transported below the drill bit 31. Then, the control device 2 controls the moving mechanism to start, so that the drill bit 31 in the first processing part arranged on the moving mechanism moves to directly above the position to be processed. Specifically, the control device 2 controls the first motor 9 to start, so that the first screw rod 10 fixedly connected to the output end of the first motor 9 rotates. Through the threaded transmission cooperation between the first screw rod 10 and the first slider 11, the first slider 11 drives the first hydraulic push rod 13 fixedly connected to it to move in the axial direction of the first screw rod 10, so that the cross-moving assembly arranged on the first hydraulic push rod 13 moves in the axial direction of the first screw rod 10 until the drill bit 31 in the first processing part moves to a position with the same ordinate as the position to be drilled;

[0091] Refer to Figures 1 to 11 , the cross-moving assembly is arranged on the first hydraulic push rod 13 and is electrically connected to the control device 2;

[0092] The cross-moving assembly includes:

[0093] The bearing block 14 is fixedly arranged at one end of the first hydraulic push rod 13 close to the processing table 1, and a cross chute 15 is opened on the surface of the bearing block 14 close to the processing table 1;

[0096] The second slider 18 is slidably arranged on the bearing block 14 and is threadedly connected to the second screw rod 17;

[0097] The second hydraulic push rod 19 is fixedly arranged on the surface of the second slider 18 close to the processing table 1 and is electrically connected to the control device 2.

[0098] During operation, the control device 2 controls the second motor 16 to start, so that the second screw rod 17 fixedly connected to the output end of the second motor 16 rotates. Through the threaded transmission cooperation between the second screw rod 17 and the second slider 18, the second slider 18 drives the second hydraulic push rod 19 fixedly connected to it to move in the axial direction of the second screw rod 17, so that the first processing part arranged on the second hydraulic push rod 19 moves in the axial direction of the second screw rod 17 until the drill bit 31 in the first processing part moves to a position with the same abscissa as the position to be drilled. At this time, the drill bit 31 is moved to directly above the position to be drilled on the plate;

[0099] The device is provided with a moving mechanism, so that the device can flexibly move the drill bit 31 in the first processing part to move the drill bit 31 in the first processing part to the corresponding position to be drilled, facilitating the subsequent drilling processing of the plate.

[0100] Refer to Figures 1 to 11 , a guiding component, having two groups, and the two groups of guiding components are symmetrically arranged on both sides of the fixed block 7;

[0101] The guiding component includes:

[0102] A wheel groove 20 is formed on the surface of the arch plate 6 away from the processing table 1;

[0103] A longitudinal groove 21 is formed through the arch plate 6;

[0104] A connecting plate 22 is fixedly arranged on the bearing block 14;

[0105] A guiding rod 23 is fixedly arranged on the connecting plate 22, and the guiding rod 23 is slidably connected with the longitudinal groove 21. One end of the guiding rod 23 away from the processing table 1 is fixedly provided with a baffle 24;

[0106] A wheel plate 25 is slidably arranged on the guiding rod 23. An auxiliary wheel 26 is arranged on the surface of the wheel plate 25 close to the processing table 1, and the auxiliary wheel 26 is in rolling connection with the wheel groove 20;

[0107] A return spring 27 is sleeved on the guiding rod 23, and the return spring 27 is located between the wheel plate 25 and the baffle 24.

[0108] When the bearing block 14 moves, the connecting plate 22 fixedly connected with the bearing block 14 also moves accordingly, so that the guiding rod 23 fixedly connected with the connecting plate 22 slides in the longitudinal groove 21 on the arch plate 6, and further the wheel plate 25 slidably connected with the guiding rod 23 drives the auxiliary wheel 26 to roll in the wheel groove 20 on the arch plate 6, thereby improving the stability of the guiding rod 23 during movement to a certain extent; it should be noted that during the process of the bearing block 14 moving towards the processing table 1, the connecting plate 22 fixedly connected with the bearing block 14 also moves towards the processing table 1, driving the guiding rod 23 fixedly connected with the connecting plate 22 to move towards the processing table 1, and at the same time, the baffle 24 fixedly connected with the guiding rod 23 compresses the return spring 27, thereby improving the stability of the bearing block 14 during movement to a certain extent.

[0109] The first processing part is arranged on the moving mechanism and is electrically connected with the control device 2 for drilling the plate;

[0110] The first processing part includes:

[0111] The motor frame 28 is fixedly arranged at one end of the second hydraulic push rod 19 close to the processing table 1;

[0112] The drilling motor 29 is arranged on the motor frame 28 and is electrically connected to the control device 2;

[0114] The drill bit 31 is arranged on the first connecting sleeve 30 and is detachably and fixedly connected to the first connecting sleeve 30.

[0115] Then, the control device 2 is used to control the first hydraulic push rod 13 to start, so that the first hydraulic push rod 13 extends, and the transverse movement assembly arranged on the first hydraulic push rod 13 moves towards the position to be drilled on the plate, so that the connecting mechanism arranged on the first processing part moves towards the position to be drilled on the plate until the cushion block 34 in the connecting mechanism fits on the surface of the processing table 1, thus completing the adjustment of the initial height of the first processing part. Then, the control device 2 is used to control the drilling motor 29 to start, so that the drill bit 31 connected to the first connecting sleeve 30 rotates. At the same time, the control device 2 is used to control the second hydraulic push rod 19 to start, so that the second hydraulic push rod 19 extends, driving the motor frame 28 fixedly connected to the second hydraulic push rod 19 to move towards the position to be drilled on the plate, so that the first motor 9 arranged on the motor frame 28 moves towards the position to be drilled on the plate, so that the drill bit 31 connected to the first connecting sleeve 30 moves towards the position to be drilled on the plate, thus completing the drilling process of the position to be drilled on the plate;

[0116] By arranging the first processing part, the device can drill the plate. Through the cooperation between the first processing part and the moving mechanism, the device can flexibly move the first processing part, thus improving the drilling range of the device to a certain extent. At the same time, it should be noted that by setting the first connecting sleeve 30 and the drill bit 31 in a detachable manner, it is convenient for the staff to replace the drilling model, thus further improving the applicable range of the device.

[0117] Refer to Figures 1 to 11 , the connecting mechanism is arranged on the first processing part;

[0118] The connecting mechanism includes:

[0119] The connecting plate 32 is fixedly arranged on the motor frame 28, and a reinforcing plate 33 is fixedly arranged on the connecting plate 32;

[0120] The bearing assembly is arranged on the connecting plate 32 and is electrically connected to the control device 2;

[0121] The bearing component includes:

[0122] A cushion block 34, located within the processing groove 3;

[0123] A bearing frame 35, fixedly arranged on the cushion block 34, and through slots 36 are formed through both sides of the bearing frame 35;

[0124] A fixing rod 37, fixedly arranged within the bearing frame 35;

[0125] A connecting block 38, fixedly arranged on the connecting plate 32 and slidably connected to the fixing rod 37. A first wedge block 39 is fixedly arranged on the surface of the connecting block 38 close to the through slot 36;

[0126] The matching part has two groups, and the two groups of matching parts are respectively arranged on the surface of the bearing frame 35 provided with the through slot 36;

[0127] The matching part includes:

[0128] A C-shaped plate 40, fixedly arranged on the surface of the bearing frame 35 provided with the through slot 36;

[0129] A plurality of first electric push rods 41, which are equidistantly arranged on the surface of the C-shaped plate 40 close to the through slot 36. The first electric push rods 41 are fixedly connected to the C-shaped plate 40 and electrically connected to the control device 2;

[0130] A rectangular block 42, fixedly arranged at one end of the first electric push rod 41 close to the through slot 36. The rectangular block 42 is slidably connected to the bearing frame 35, and a plurality of equally spaced placement grooves 43 are formed on the surface of the rectangular block 42 close to the fixing rod 37;

[0131] A connecting spring 44, arranged within the placement groove 43, and one end of the connecting spring 44 close to the C-shaped plate 40 is fixedly connected to the rectangular block 42;

[0132] A second wedge block 45, arranged on the rectangular block 42. The second wedge block 45 is slidably connected to the placement groove 43, and the second wedge block 45 is used to cooperate with the first wedge block 39 to slide within the placement groove 43.

[0133] It should be noted that when the motor frame 28 moves in the direction of the position on the plate to be drilled, at this time, the connecting plate 32 fixedly connected to the motor frame 28 also moves in the direction of the processing table 1, so that the cushion block 34 fixedly connected to the bearing frame 35 moves in the direction of the processing table 1 until the cushion block 34 contacts the processing table 1. Then, as the connecting plate 32 continues to move downward, since the cushion block 34 has contacted the processing table 1 at this time, as the connecting plate 32 continues to move downward, the connecting block 38 fixedly connected to the connecting plate 32 drives the first wedge block 39 to slide downward. By applying forces to the adjacent second wedge blocks 45 respectively through the first wedge blocks 39 on both sides of the connecting block 38, the second wedge blocks 45 in contact with the first wedge block 39 slide into the placement groove 43, so that the connecting block 38 can drive the first wedge blocks 39 on both sides to move downward until the drill bit 31 moves to the position where drilling is completed;

[0134] Referring to Figures 1 to 11 , a telescopic assembly, arranged on the bearing assembly and electrically connected to the control device 2;

[0135] The telescopic assembly includes:

[0136] A second electric push rod 46, fixedly arranged on the bearing frame 35 and electrically connected to the control device 2;

[0137] A cross plate 47, fixedly arranged at one end of the second electric push rod 46 close to the arch plate 6.

[0138] A second processing part, arranged on the connecting mechanism and electrically connected to the control device 2, for polishing the holes drilled on the plate;

[0139] The second processing part includes:

[0140] A polishing motor 48, fixedly arranged on the cross plate 47 and electrically connected to the control device 2;

[0141] A second connecting sleeve 49, fixedly arranged on the output end of the polishing motor 48;

[0142] A polishing column 50, arranged on the second connecting sleeve 49 and detachably and fixedly connected to the second connecting sleeve 49. In the initial state, the axis of the polishing column 50 coincides with the axis of the drill bit 31;

[0143] A positioner 51, fixedly arranged on the cross plate 47 and electrically connected to the control device 2. The positioner 51 is used to position the axis of the drill bit 31 and keep the axis of the polishing column 50 coinciding with the axis of the drill bit 31.

[0144] Referring to Figures 1 to 11, after the drill bit 31 finishes drilling the plate, the positioner 51 positions the axis of the drill bit 31. After positioning, the control device 2 controls the polishing motor 48 to start, so that the second connecting sleeve 49 fixedly connected to the output end of the polishing motor 48 rotates, causing the polishing column 50 connected to the second connecting sleeve 49 to rotate. Then, the control device 2 controls the second electric push rod 46 to start, so that the cross plate 47 fixedly connected to the second electric push rod 46 moves until the polishing column 50 is moved to a position coinciding with the axis of the drill bit 31. Then, the control device 2 controls the second hydraulic push rod 19 to shorten, so that the motor frame 28 fixedly connected to the second hydraulic push rod 19 moves away from the processing table 1, thereby driving the connecting plate 32 fixedly connected to the motor frame 28 to move away from the processing table 1. As a result, the connecting block 38 fixedly connected to the connecting plate 32 drives the first wedge block 39 to move away from the processing table 1. Through the cooperation between the first wedge block 39 and the adjacent second wedge block 45, the second wedge block 45 adjacent to the first wedge block 39 drives the rectangular block 42 to move upward, so that the first electric push rod 41 fixedly connected to the rectangular block 42 drives the C-shaped plate 40 to move upward, thereby driving the bearing frame 35 fixedly connected to the C-shaped plate 40 to move upward. The second electric push rod 46 fixedly connected to the bearing frame 35 drives the cross plate 47 to move upward, so that the polishing motor 48 provided on the cross plate 47 moves upward, and then the polishing column 50 connected to the connecting sleeve also moves upward, thus realizing the polishing process of the drilled hole below the drill bit 31, and to a certain extent improving the processing efficiency of the device; when the polishing column 50 finishes polishing the drilled hole on the plate, the control device 2 controls the first electric push rod 41 to contract, so that the rectangular block 42 fixedly connected to the first electric push rod 41 slides away from the fixed rod 37, thereby driving the connecting spring 44 provided in the placement groove 43 to pull the second wedge block 45 to slide away from the fixed rod 37 until the second wedge block 45 in contact with the first wedge block 39 disengages from the first wedge block 39. At this time, the second wedge block 45 loses the support force of the first wedge block 39 on it, so that the bearing frame 35 drives the second processing part provided on the cross plate 47 to reset, which is convenient for the next polishing operation.

[0145] The device is provided with a connecting mechanism, so that after the device finishes drilling the plate, during the process of the drill bit 31 moving away from the processing table 1, the connecting mechanism drives the second processing part to also move away from the processing table 1, so that the inner surface of the drilled hole on the plate is polished during the reset process of the drill bit 31, thereby greatly improving the processing efficiency of the device for the plate.

[0146] Working principle: Refer to Figures 1 to 11, when it is necessary to drill through the plate, the control device 2 is used to control the electric telescopic shaft to start, so that the plate is transported by the rotation of the electric telescopic shaft until the area of the plate to be processed is transported below the drill bit 31. Then, the control device 2 is used to control the moving mechanism to start, so that the drill bit 31 in the first processing part arranged on the moving mechanism moves directly above the position to be processed. Specifically, the control device 2 is used to control the first motor 9 to start, so that the first screw rod 10 fixedly connected to the output end of the first motor 9 rotates. Through the threaded transmission cooperation between the first screw rod 10 and the first slider 11, the first slider 11 drives the first hydraulic push rod 13 fixedly connected to it to move in the axial direction of the first screw rod 10, so that the transverse movement assembly arranged on the first hydraulic push rod 13 moves in the axial direction of the first screw rod 10 until the drill bit 31 in the first processing part moves to a position with the same ordinate as the position to be drilled; then, the control device 2 is used to control the second motor 16 to start, so that the second screw rod 17 fixedly connected to the output end of the second motor 16 rotates. Through the threaded transmission cooperation between the second screw rod 17 and the second slider 18, the second slider 18 drives the second hydraulic push rod 19 fixedly connected to it to move in the axial direction of the second screw rod 17, so that the first processing part arranged on the second hydraulic push rod 19 moves in the axial direction of the second screw rod 17 until the drill bit 31 in the first processing part moves to a position with the same abscissa as the position to be drilled. At this time, the drill bit 31 is moved directly above the position to be drilled on the plate;

[0147] Then, the control device 2 is used to control the first hydraulic push rod 13 to start, so that the first hydraulic push rod 13 extends, and the transverse movement assembly arranged on the first hydraulic push rod 13 moves towards the position to be drilled on the plate, so that the connecting mechanism arranged on the first processing part moves towards the position to be drilled on the plate until the cushion block 34 in the connecting mechanism fits on the surface of the processing table 1, thus completing the adjustment of the initial height of the first processing part. Then, the control device 2 is used to control the drilling motor 29 to start, so that the drill bit 31 connected to the first connecting sleeve 30 rotates. At the same time, the control device 2 is used to control the second hydraulic push rod 19 to start, so that the second hydraulic push rod 19 extends, driving the motor frame 28 fixedly connected to the second hydraulic push rod 19 to move towards the position to be drilled on the plate, so that the first motor 9 arranged on the motor frame 28 moves towards the position to be drilled on the plate, so that the drill bit 31 connected to the first connecting sleeve 30 moves towards the position to be drilled on the plate, thus completing the through drilling process of the position to be drilled on the plate;

[0148] It should be noted that when the motor frame 28 moves in the direction of the position on the plate to be drilled, at this time, the connecting plate 32 fixedly connected to the motor frame 28 also moves in the direction of the processing table 1, so that the cushion block 34 fixedly connected to the bearing frame 35 moves in the direction of the processing table 1 until the cushion block 34 contacts the processing table 1. Then, as the connecting plate 32 continues to move downward, since the cushion block 34 has contacted the processing table 1 at this time, as the connecting plate 32 continues to move downward, the connecting block 38 fixedly connected to the connecting plate 32 drives the first wedge block 39 to slide downward. By applying forces to the adjacent second wedge blocks 45 respectively through the first wedge blocks 39 on both sides of the connecting block 38, the second wedge blocks 45 in contact with the first wedge block 39 slide into the placement groove 43, and further the connecting block 38 can drive the first wedge blocks 39 on both sides to move downward until the drill bit 31 moves to the position where drilling is completed;

[0149] After the drill bit 31 finishes drilling the plate, the positioner 51 locates the position of the axis of the drill bit 31. After the positioning is completed, the control device 2 controls the polishing motor 48 to start, so that the second connecting sleeve 49 fixedly connected to the output end of the polishing motor 48 rotates, causing the polishing column 50 connected to the second connecting sleeve 49 to rotate. Then, the control device 2 controls the second electric push rod 46 to start, so that the cross plate 47 fixedly connected to the second electric push rod 46 moves until the polishing column 50 is moved to a position coinciding with the axis of the drill bit 31. Then, the control device 2 controls the second hydraulic push rod 19 to shorten, so that the motor frame 28 fixedly connected to the second hydraulic push rod 19 moves away from the processing table 1, thereby driving the connecting plate 32 fixedly connected to the motor frame 28 to move away from the processing table 1. Thus, the connecting block 38 fixedly connected to the connecting plate 32 drives the first wedge block 39 to move away from the processing table 1. Through the cooperation between the first wedge block 39 and the adjacent second wedge block 45, the second wedge block 45 adjacent to the first wedge block 39 drives the rectangular block 42 to move upward, so that the first electric push rod 41 fixedly connected to the rectangular block 42 drives the C-shaped plate 40 to move upward, thereby driving the bearing frame 35 fixedly connected to the C-shaped plate 40 to move upward. The second electric push rod 46 fixedly connected to the bearing frame 35 drives the cross plate 47 to move upward, so that the polishing motor 48 provided on the cross plate 47 moves upward, and thus the polishing column 50 connected to the connecting sleeve also moves upward, realizing the polishing process of the drilled hole below the drill bit 31, and to a certain extent improving the processing efficiency of the device. When the polishing column 50 finishes the polishing process of the hole drilled in the plate, the control device 2 controls the first electric push rod 41 to contract, so that the rectangular block 42 fixedly connected to the first electric push rod 41 slides away from the fixed rod 37, thereby driving the connecting spring 44 provided in the placement groove 43 to pull the second wedge block 45 to slide away from the fixed rod 37 until the second wedge block 45 in contact with the first wedge block 39 disengages from the first wedge block 39. At this time, the second wedge block 45 loses the support force of the first wedge block 39, so that the bearing frame 35 drives the second processing part provided on the cross plate 47 to reset, facilitating the next polishing operation.
