Description

Technical Field

[0001] The invention relates to the technical field of drilling equipment, in particular to a device for drilling oblique holes in container locks. Background Art

[0002] In the processing of inclined holes for container locks, it is necessary to follow the principle of drilling the surface first and then the hole. Otherwise, the distance between the axis of the drilled hole and the reference plane will be out of tolerance, the angle will be unqualified, or the geometric tolerances such as position accuracy will not meet the requirements of the drawing. The operation of drilling the surface first and then the hole is to use a flat-bottomed tool, that is, a flat-head drill bit, to process the guide plane before drilling the inclined hole. This guide plane is perpendicular to the axis of the hole, which can make the subsequent drill bit well centered and ensure the quality of the drilling. Existing processing often only uses one drill bit, and the drilling operation is divided into two stages, that is, drilling the guide plane first and then drilling the hole. However, drilling the guide plane requires a drill bit with better rigidity, while drilling the hole requires a longer drill bit. Longer drill bits are unstable and may swing, affecting product quality and the life of the drill bit. At the same time, the drill bits of existing equipment often need to be manually disassembled, and the disassembly process will affect the support work, which is not conducive to efficient production.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1 and Figure 2 The container lock oblique hole drilling device includes a machine body 1, which serves as a platform for mounting related components. A workstation is located in the center of the machine body 1. A vertically positioned lifting arm 2 is installed within the workstation. A drilling rig is mounted on the lifting arm 2, and a matching curved plate 3 is positioned below the drilling rig. A drill assembly is mounted on the curved plate 3, and a control mechanism for driving the curved plate 3 is provided on the lifting arm 2. The machine body 1 is symmetrically equipped with two chambers 4, each fitted with a cabinet door. Inside each chamber 4, a horizontally mounted electric telescopic rod 5 is positioned, with its telescopic ends facing each other and equipped with a docking mechanism that mates with the curved plate 3. Drilling mechanisms are located within each chamber 4, and a workpiece placement mechanism, specifically for machining parts, is located at the bottom of the workstation space of the machine body 1.

[0021] A second oil cylinder is installed on the top of the machine body 1 to control the lifting arm 2 to move up and down.

[0022] Reference Figure 3-5 The drilling rig includes a drive motor 6 mounted at the bottom of the lifting arm 2. A gearbox is mounted at the bottom of the lifting arm 2, housing a set of meshing gears. The gearbox's bottom transmission is equipped with an insert block 7, coaxially aligned with the lifting arm 2. The insert block 7 is connected to the drive motor 6 via the gearbox. The drive motor 6 drives the insert block 7, which in turn increases its torque. The drive motor 6's shaft transmits power to the gear set within the gearbox, ultimately driving the insert block 7 to rotate.

[0023] As a technical optimization solution of the present invention, the drill bit assembly includes two mounting seats 8 symmetrically fixed on the curved plate 3. The two mounting seats 8 are located at both ends of the curved plate 3. Both mounting seats 8 are detachably fixed with sleeves 9, and the sleeves 9 and mounting seats 8 are fixed by bolts. A rotating core 10 is coaxially rotated inside the sleeve 9. One end of the rotating core 10 is used to mount the drill bit, and the radius of the end of the rotating core 10 used to mount the drill bit is the same as the radius of the sleeve 9. The two sleeves 9 correspond to two drill bits of different specifications, and the curved plate 3 is provided with a through hole corresponding to the coaxial sleeve 9. The two drill bits of different specifications are a short-shank flat-head drill bit and a long-shank reaming drill bit. The short-shank flat-head drill bit has better rigidity and effectively ensures that the center position of the drill hole does not change, which is convenient for drilling inclined holes and obtaining a guide hole. The long-shank reaming drill bit is longer and is used to drill through the part to complete the final drilling operation.

[0024] As a technical optimization solution of the present invention, the rotating core 10 can be coaxially aligned with the plug-in block 7. The rotating core 10 is provided with a slot 11 that matches the plug-in block 7. The plug-in block 7 is inserted into the slot 11, which can drive the rotating core 10 to rotate. The plug-in block 7 and the slot 11 can be plugged in during the movement.

[0025] As a technical optimization solution of the present invention, the control mechanism includes a first oil cylinder 12 fixedly connected in parallel with the lifting arm 2. The telescopic end of the first oil cylinder 12 faces downward and is fixed with a mounting plate 13. The first oil cylinder 12 can accurately drive the mounting plate 13 to move up and down. A semicircular fixed plate 14 is fixed to the side of the mounting plate 13 close to the lifting arm 2. The side of the semicircular fixed plate 14 is provided with a fan-shaped rotating disk 15. The fan-shaped rotating disk 15 is symmetrically fixed with two slide rails 16. The two ends of the arc plate 3 can slide and fit with the two slide rails 16, which has a stabilizing effect. A positioning block 17 is fixed in the middle of the edge of the fan-shaped rotating disk 15. A slider 18 is fixed in the middle of the arc plate 3. The positioning block 17 is provided with a slide groove that slides with the slider 18. A first electric push rod 19 is vertically fixed on the positioning block 17. The telescopic end of the first electric push rod 19 slides through the positioning block 17, and the slider 18 is provided with a corresponding groove that plugs into the telescopic end of the first electric push rod 19. The telescopic end of the first electric push rod 19 slides through the groove of the positioning block 17 and the slider 18 to be plugged into, so as to fix the curved plate 3 and the fan-shaped rotating disk 15. The first oil cylinder 12 controls the lifting of the mounting plate 13, which can drive the corresponding fan-shaped rotating disk 15 and the curved plate 3 to rise and fall.

[0026] As a technical optimization solution of the present invention, the semicircular fixed plate 14 is provided with an arc track that is slidably connected to the fan-shaped rotating disk 15. A rotating motor 20 is fixed between the semicircular fixed plate 14 and the mounting plate 13. A gear 21 is coaxially fixed to the rotating motor 20. An arc-shaped rack 22 is fixed to the side of the fan-shaped rotating disk 15. The gear 21 is meshed with the arc-shaped rack 22. When the rotating motor 20 is started, the rotating motor 20 can accurately drive the gear 21 to rotate. The gear 21 drives the fan-shaped rotating disk 15 to rotate accurately through the arc-shaped rack 22, thereby adjusting the rotation of the two arc plates 3 and ultimately swapping the positions of the two drill bits. A second electric push rod 23 is also fixed between the semicircular fixed plate 14 and the mounting plate 13. The telescopic end of the second electric push rod 23 slides through the semicircular fixed plate 14. The fan-shaped rotating disk 15 is provided with two circular holes 24. The two circular holes 24 can be inserted and matched with the telescopic end of the second electric push rod 23. The telescopic end of the second electric push rod 23 slides through the semicircular fixed plate 14 and is inserted into a circular hole 24, thereby stably positioning and fixing the fan-shaped rotating disk 15 after rotation adjustment. The two circular holes 24 on the fan-shaped rotating disk 15 correspond to two positions, that is, the curved plate 3 can be rotated and adjusted into two positions, and the two positions correspond to the two drill bits respectively, so that both drill bits can be corresponding to the drilling station.

[0027] As a technical optimization solution of the present invention, the docking mechanism includes a docking block 25 fixed to the telescopic end of the electric telescopic rod 5. Two rubber rods 26 are fixed to one side of the docking block 25. Slots are provided on both sides of the curved plate 3 to accommodate the two rubber rods 26 in a damped plug-in manner. The two rubber rods 26 on the docking block 25 can be inserted into the slots on one side of the curved plate 3 with a damped plug-in, thus achieving an effective plug-in connection.

[0028] As a technical optimization solution of the present invention, a parts setting plate 27 is also slidably mounted on the telescopic rod of the electric telescopic rod 5. The parts setting plate 27 can be fixed to the telescopic rod of the electric telescopic rod 5 via a tightening knob. The parts setting plate 27 is provided with a number of pipe clamping grooves, which can be used to install relevant pipes, such as coolant spray pipes, negative pressure vacuum pipes, and air blower pipes, which can be used for flexible use during drilling work. The cavity 4 has a rectangular opening corresponding to the electric telescopic rod 5. The telescopic rod of the electric telescopic rod 5 is also mounted and fixed with a spring. One end of the spring is fixed with a closed door 28 that slides and matches the telescopic rod of the electric telescopic rod 5. The closed door 28 can be placed against the inside of the rectangular opening.

[0029] Reference Figure 6 and Figure 7The drill bit grinding mechanism includes a U-shaped block 29 arranged at the bottom of the cavity 4. A third electric push rod 30 is installed in the machine body 1 to drive the U-shaped block 29 to rise and fall. The third electric push rod 30 can be activated to control the precise rise of the U-shaped block 29. Cylinders 31 are horizontally fixed on both sides of the U-shaped block 29. The telescopic ends of the two cylinders 31 are arranged opposite to each other, and are fixed with arc-shaped clamping blocks 32. The two cylinders 31 can be synchronously and accurately started, thereby driving the two arc-shaped clamping blocks 32 to perform clamping operations. A hole aligned with the U-shaped block 29 is provided at the bottom of the cavity 4, and a belt grinder 33 is provided on one side of the U-shaped block 29. The belt grinder 33 is an existing device and will not be described in detail here. The belt grinder 33 can also be replaced with an angle grinder. The belt grinder 33 is arranged at an angle and is used to perform sharpening operations on the drill bit, thereby maintaining the drill bit.

[0030] Reference Figure 2 The workpiece placement mechanism includes a workbench 34 positioned at the bottom of the workstation space within the machine body 1. The workbench 34 is horizontally slidably connected to the machine body 1. Two bench vises 35 are symmetrically mounted on the workbench 34. The bench vises 35 are conventional devices and will not be described in detail here. The vises 35 are manually controlled for clamping, but can also be replaced with existing electrically controlled clamping. The workbench 34 is driven by a hydraulic cylinder, enabling precise azimuth movement.

[0031] When the present invention is in use, the lock head part to be processed is first fixed on the work station, that is, fixed on the workbench 34, ensuring that a drill bit corresponds to it, and the drill bit is a short-shank flat-head drill bit, then the lifting arm 2 is started and controlled to descend, and the driving motor 6 is started and finally drives the plug block 7 to rotate, and the plug block 7 drives the rotating core 10 that is plugged in and matched with it to rotate, and then drives the corresponding drill bit to perform drilling operations. The drill bit is a short-shank flat-head drill bit with good rigidity, which effectively ensures that the center position of the drill hole will not change, and is convenient for drilling inclined holes. After that, the guide hole mouth is obtained, that is, the guide plane is obtained. After obtaining the guide hole, the rotating motor 20 is started, which drives the gear 21 to rotate. The gear 21 drives the fan-shaped rotating disk 15 to rotate through the arc rack 22, thereby rotating and adjusting the two arc plates 3, and finally swapping the positions of the two drill bits. At this time, the drill height corresponding to the vertical height of the part is the long-rod reaming drill bit. After that, the lifting arm 2 is lowered again, and the drive motor 6 is started, and finally the drill bit is driven to rotate, thereby finally completing the drilling operation. By swapping two drill bits of different specifications, the locking head oblique hole drilling process can be efficiently achieved, avoiding the low efficiency of a single drill bit and avoiding problems such as easy damage to the parts.

[0032] When the fan-shaped rotating disk 15 and the arc plate 3 are rotated and adjusted, it is necessary to first control the lifting arm 2 to rise, and then control the mounting plate 13 to descend a set distance through the first oil cylinder 12, which ultimately drives the corresponding fan-shaped rotating disk 15 and the arc plate 3 to separate from the insert block 7, so that the insert block 7 is separated from the slot 11 of the corresponding rotating core 10, and then the fan-shaped rotating disk 15 and the arc plate 3 can be rotated and adjusted without obstruction. Each time after the sector-shaped rotating disk 15 and the curved plate 3 are rotated and adjusted, the second electric push rod 23 can be started, and the telescopic end of the second electric push rod 23 slides through the semicircular fixed plate 14 and is inserted into a circular hole 24, so that the sector-shaped rotating disk 15 after rotation adjustment is stably positioned and fixed, and the two circular holes 24 on the sector-shaped rotating disk 15 correspond to two positions, that is, the curved plate 3 can be rotated and adjusted to two positions, and the two positions correspond to two drill bits respectively, so that both drill bits can correspond to the drilling station. When the sector-shaped rotating disk 15 is rotated, ensure that the telescopic end of the second electric push rod 23 is not plugged into the circular hole 24.

[0033] In the above operation, the curved plate 3 and the fan-shaped rotating disk 15 are fixed by the sliding fit between the two ends of the curved plate 3 and the two slide rails 16, and the sliding fit between the positioning block 17 and the slider 18. The telescopic end of the first electric push rod 19 slides through the grooves of the positioning block 17 and the slider 18 to insert and finally achieve fixation. Therefore, the curved plate 3 can also be removed by the same principle. When it is necessary to remove the curved plate 3, the first electric push rod 19 is controlled to separate the telescopic end of the first electric push rod 19 from the groove of the slider 18, and the insert block 7 is ensured to be separated from the slot 11 of the corresponding rotating core 10. At this time, the curved plate 3 can be removed.

[0034] This device can automatically remove the curved plate 3 by starting the electric telescopic rod 5 located on one side of the machine body 1. The telescopic end of the electric telescopic rod 5 extends, driving the corresponding docking block 25 to move, and finally making the two rubber rods 26 on the docking block 25 damped and plugged into the slots on one side of the curved plate 3, thereby achieving an effective plug-in connection. Thereafter, the telescopic end of the first electric push rod 19 is controlled to separate from the groove of the slider 18, and ensure that the plug-in block 7 is separated from the slot 11 of the corresponding rotating core 10. At this time, the electric telescopic rod 5 can be started to retract, so that the docking block 25 drives the curved plate 3 to disengage from the fan-shaped rotating disk 15. The curved plate 3 can be disengaged from both sides of the fan-shaped rotating disk 15.

[0035] After the arc plate 3 is detached, the arc plate 3 can be driven to move into the cavity 4 and accurately driven to move above the U-shaped block 29. At this time, the third electric push rod 30 can be started to control the U-shaped block 29 to rise, so that the two arc clamping blocks 32 correspond to one rotating core 10. Then, the two cylinders 31 can be started synchronously to drive the two arc clamping blocks 32 to clamp the rotating core 10 to ensure that the rotating core 10 is fixed and does not rotate. Then, the electric telescopic rod 5 is started to separate the docking block 25 from the arc plate 3. At this time, the third electric push rod 30 can be started to drive the U-shaped block 29 to rise and fall, that is, to drive the arc plate 3 and the corresponding rotating core 10 to rise and fall, so that the end of the corresponding drill bit can be moved to the side of the belt grinder 33. At this time, the belt grinder 33 can be started to perform a sharpening and maintenance operation on the end of the drill bit. During the sharpening maintenance operation, the hole aligned with the U-shaped block 29 at the bottom of the cavity 4 is convenient for setting drill bits of different lengths, and the rotating core 10 can be manually rotated and adjusted to ensure that the drill bits can be fully sharpened and maintained.

[0036] It can be concluded from the above operation that by setting up multiple curved plates 3 and moving the positions of the multiple curved plates 3, when one curved plate 3 is in normal use, the other curved plate 3 can be maintained, thereby ensuring the continuity of the drilling process, effectively ensuring work efficiency, and avoiding the maintenance operation of a single curved plate 3 affecting work efficiency.

[0037] The parts setting plates 27 on the two electric telescopic rods 5 of the present device correspond to a number of pipe clamping grooves, which can be used to install relevant pipes, such as coolant spray pipes, negative pressure dust suction pipes, blow pipes and other pipes, which can be used for flexible use during drilling work, and the telescopic movement of the two electric telescopic rods 5 can realize the movement operation of a number of pipes, achieving flexible and comprehensive use effects. For example, the blow pipe operation can be moved to achieve a more comprehensive blowing operation, that is, to achieve a comprehensive air-drying effect.

[0038] At the same time, the workbench 34 provided in the device can replace the positions of the two bench vises 35, so that when one bench vise 35 clamps the part and corresponds to the work station, the other bench vise 35 also clamps the part and waits. After the drilling is completed, the next drilling operation can be carried out quickly, effectively improving the drilling work efficiency.

[0039] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
