Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, and more particularly to a device for drilling inclined holes in container lock heads. Background Technology

[0002] In the machining of angled holes for container lock heads, the principle of "face first, hole later" must be followed. Otherwise, the distance between the drilled hole's axis and the reference surface will exceed tolerances, the angle will be unqualified, or the geometric tolerances such as positional accuracy will fail to meet the drawing requirements. Specifically, before drilling the angled hole, a flat-bottomed tool, i.e., a flat-headed drill bit, is generally used to machine a guide plane. This guide plane is perpendicular to the hole axis, which allows the subsequent drill bit to be well centered and ensures drilling quality. However, existing machining often uses only one type of drill bit, performing a two-stage drilling operation: drilling the guide plane first and then drilling the hole. However, drilling the guide plane requires a drill bit with good rigidity, while drilling the hole requires a longer drill bit. Longer drill bits are prone to instability and wobbling, affecting product quality and drill bit life. In addition, the drill bits in existing equipment often need to be manually disassembled, which affects the support work and is not conducive to efficient production.

[0003] Therefore, in order to solve such problems, we proposed a container lock head oblique hole drilling device. Summary of the Invention

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Reference Figure 1 and Figure 2 A container lock head oblique hole drilling processing device includes a machine base 1, which serves as a platform for mounting related components. A workstation space is located in the middle of the machine base 1, within which a lifting arm 2 is vertically mounted. A drilling rig is installed on the lifting arm 2, and an arc-shaped plate 3 is positioned below the drilling rig. A drill bit assembly is mounted on the arc-shaped plate 3, and a control mechanism for driving the arc-shaped plate 3 is located on the lifting arm 2.

[0030] The main body 1 of the machine tool has two symmetrically arranged cavities 4, each with a cabinet door. Electric telescopic rods 5 are horizontally installed inside each cavity 4, with their telescopic ends facing each other and each equipped with a docking mechanism that matches the arc-shaped plate 3. Both cavities 4 also have a drill grinding mechanism. A workpiece placement mechanism is located at the bottom of the workstation space of the main body 1; this workpiece placement mechanism is used for processing parts.

[0031] The top of the main body 1 of the machine is equipped with a second hydraulic cylinder for controlling the lifting arm 2 to move up and down.

[0032] Reference Figure 3-5 The drilling rig includes a drive motor 6 mounted at the bottom of the lifting arm 2. A gearbox is installed at the bottom of the lifting arm 2, and the gearbox contains a set of meshing gears. A drive block 7, coaxially aligned with the lifting arm 2, is located at the bottom of the gearbox. The drive block 7 is connected to the drive motor 6 via the gearbox, enabling the drive motor 6 to rotate the drive block 7. The gearbox increases the rotational torque of the drive block 7. The shaft of the drive motor 6 transmits power to the gear set inside the gearbox, ultimately driving the drive block 7 to rotate.

[0033] As a technical optimization of the present invention, the drill bit assembly includes two mounting seats 8 symmetrically fixed on the arc-shaped plate 3. The two mounting seats 8 are located at opposite ends of the arc-shaped plate 3, and each mounting seat 8 can be detachably fixed with a sleeve block 9. The sleeve block 9 and the mounting seat 8 can be fixed with bolts. A rotating core 10 is coaxially rotatable inside the sleeve block 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 block 9. The two sleeve blocks 9 correspond to two drill bits of different specifications. The arc-shaped plate 3 has through holes coaxially corresponding to the sleeve blocks 9. The two drill bits of different specifications are a short-rod flat-head drill bit and a long-rod reaming drill bit. The short-rod flat-head drill bit has better rigidity, effectively ensuring 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-rod reaming drill bit is longer and is used to drill through the part to complete the final drilling operation.

[0034] As a technical optimization of the present invention, the rotating core 10 can be coaxially aligned with the insert block 7. The rotating core 10 is provided with a slot 11 that matches the insert block 7. The insert block 7 is inserted into the slot 11, which can drive the rotating core 10 to rotate. The insert block 7 and the slot 11 can be inserted during the movement.

[0035] As a technical optimization of the present invention, the control mechanism includes a first hydraulic cylinder 12 fixedly connected in parallel with the lifting arm 2. The telescopic end of the first hydraulic cylinder 12 faces downward and is fixed with a mounting plate 13. The first hydraulic cylinder 12 can precisely drive the mounting plate 13 to move and lift. A semi-circular fixing plate 14 is fixed on the side of the mounting plate 13 near the lifting arm 2. A fan-shaped rotating disk 15 is rotatably provided on the side of the semi-circular fixing plate 14. Two slide rails 16 are symmetrically fixed on the fan-shaped rotating disk 15. 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 sliding groove that matches 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 groove that corresponds to 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, thus fixing the arc plate 3 and the fan-shaped rotating disk 15. The mounting plate 13 is raised and lowered by controlling the first hydraulic cylinder 12, which in turn drives the corresponding fan-shaped rotating disk 15 and arc plate 3 to rise and fall.

[0036] As a technical optimization of the present invention, the semi-circular fixing plate 14 is provided with an arc-shaped track that is slidably connected to the fan-shaped rotating disk 15. A rotating motor 20 is fixed between the semi-circular fixing 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 and the arc-shaped rack 22 mesh and match. When the rotating motor 20 is started, the rotating motor 20 can precisely drive the gear 21 to rotate. The gear 21 drives the fan-shaped rotating disk 15 to rotate precisely through the arc-shaped rack 22, thereby adjusting the rotation of the two arc-shaped plates 3, and finally changing the position of the two drill bits. A second electric push rod 23 is also fixed between the semi-circular fixing plate 14 and the mounting plate 13. The telescopic end of the second electric push rod 23 slides through the semi-circular fixing plate 14. The fan-shaped rotating disk 15 is provided with two round holes 24, which 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 semi-circular fixed plate 14 and inserts into a round hole 24, thereby stably positioning and fixing the fan-shaped rotating disk 15 after rotation adjustment. The two round holes 24 on the fan-shaped rotating disk 15 correspond to two positions, that is, the arc plate 3 can rotate and adjust to two directions, and the two directions correspond to two drill bits respectively, so that both drill bits can be aligned with the drilling position.

[0037] As a technical optimization 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, and slots are provided on both sides of the arc-shaped plate 3 to be damped and matched with the two rubber rods 26. The two rubber rods 26 on the docking block 25 can be damped and inserted into the slots on one side of the arc-shaped plate 3, thus achieving an effective insertion connection.

[0038] As a technical optimization of the present invention, a parts setting plate 27 is slidably sleeved 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 by a fastening knob. The parts setting plate 27 is provided with several pipe clamping grooves, which can be used to install relevant pipes, such as coolant spray pipes, negative pressure dust suction pipes, blower pipes, etc., which can be used flexibly during drilling work. The cavity 4 is provided with a rectangular opening corresponding to the electric telescopic rod 5. A spring is also sleeved and fixed on the telescopic rod of the electric telescopic rod 5. One end of the spring is fixed with a closing door 28 that slides and matches the telescopic rod of the electric telescopic rod 5. The closing door 28 can be set to abut against the inside of the rectangular opening.

[0039] Reference Figure 6 and Figure 7The drill bit sharpening mechanism includes a U-shaped block 29 located at the bottom of the cavity 4. A third electric push rod 30 is installed inside the main 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. Two cylinders 31 are horizontally fixed on both sides of the U-shaped block 29. The extension and retraction ends of the two cylinders 31 are positioned opposite each other and are each fixed with an arc-shaped clamping block 32. The two cylinders 31 can be activated synchronously and precisely, thereby driving the two arc-shaped clamping blocks 32 to perform clamping operations. The bottom of the cavity 4 has holes aligned with the U-shaped block 29, and a belt grinder 33 is located 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 inclined and used to sharpen the drill bit, thus maintaining its performance.

[0040] Reference Figure 2 The workpiece placement mechanism includes a worktable 34 located at the bottom of the workstation space of the machine body 1. The worktable 34 is horizontally slidably connected to the machine body 1. Two bench vises 35 are symmetrically arranged on the worktable 34. The bench vises 35 are existing devices and will not be described in detail here. The bench vises 35 are manually controlled for clamping operations, but can also be replaced with existing electrically controlled clamping operations. The worktable 34 is driven to move by a hydraulic cylinder, enabling precise positional movement.

[0041] In use, the lock head part to be processed is first fixedly placed on the workstation, i.e., fixed on the workbench 34, ensuring that a drill bit corresponds to it. The drill bit is a short-rod flat-head drill bit. Then, the lifting arm 2 is started and controlled to descend. At the same time, the drive motor 6 is started and eventually drives the insert block 7 to rotate. The insert block 7 drives the rotating core 10 that is plugged into it to rotate, thereby driving the corresponding drill bit to perform drilling operations. The drill bit is a short-rod flat-head drill bit with good rigidity, which effectively ensures that the center position of the drill hole does not change, which is convenient for drilling inclined holes. After that, a guide hole is obtained, i.e., a guide plane is obtained. After obtaining the guide hole, the rotary 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-shaped rack 22, thereby adjusting the rotation of the two arc-shaped plates 3. Ultimately, the positions of the two drill bits are switched. At this point, the drilling height corresponding to the vertical position of the part is the long-rod reaming drill bit. Then, the lifting arm 2 is lowered again, and the drive motor 6 is started, ultimately driving the drill bit to rotate, thus completing the drilling operation. By switching between two drill bits of different specifications, the drilling of the lock-head inclined hole can be efficiently realized, avoiding the low efficiency of a single drill bit and the problem of easily damaging the part.

[0042] When adjusting the rotation of the fan-shaped rotating disk 15 and the arc plate 3, the lifting arm 2 needs to be raised first, and then the mounting plate 13 is lowered by a set distance through the first oil cylinder 12. This will eventually cause the corresponding fan-shaped rotating disk 15 and 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. After that, the fan-shaped rotating disk 15 and arc plate 3 can be adjusted without obstruction. After each rotation and adjustment of the fan-shaped rotating disk 15 and the arc plate 3, the second electric push rod 23 can be activated. The telescopic end of the second electric push rod 23 slides through the semi-circular fixed plate 14 and inserts into a round hole 24, thereby stably positioning and fixing the fan-shaped rotating disk 15 after rotation and adjustment. The two round holes 24 on the fan-shaped rotating disk 15 correspond to two positions, that is, the arc plate 3 can be rotated and adjusted to two directions. The two directions correspond to two drill bits respectively, so that the two drill bits can be aligned with the drilling position. When the fan-shaped rotating disk 15 is rotated, it must be ensured that the telescopic end of the second electric push rod 23 is not inserted into the round hole 24.

[0043] In the above operation, the arc-shaped plate 3 and the fan-shaped rotating disk 15 are fixed by the sliding engagement of both ends of the arc-shaped plate 3 with the two slide rails 16, and the sliding engagement of the positioning block 17 with the slider 18. The fixing is achieved by the sliding end of the first electric push rod 19 penetrating through the grooves of the positioning block 17 and the slider 18. Similarly, the arc-shaped plate 3 can also be disassembled. When it is necessary to disassemble the arc-shaped plate 3, the first electric push rod 19 is controlled to separate its extension end from the groove of the slider 18, ensuring that the insertion block 7 separates from the slot 11 of the corresponding rotating core 10. At this point, the arc-shaped plate 3 can be removed.

[0044] This device can automatically remove the arc plate 3. By activating 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. Finally, the two rubber rods 26 on the docking block 25 are damped and inserted into the slot on one side of the arc plate 3, thus achieving an effective insertion connection. Then, the telescopic end of the first electric push rod 19 is controlled to separate from the groove of the slider 18, and the insertion block 7 is separated from the slot 11 of the corresponding rotating core 10. At this time, the electric telescopic rod 5 can be activated to retract, thereby causing the docking block 25 to drive the arc plate 3 to detach from the fan-shaped rotating disk 15. The arc plate 3 can be detached from both sides of the fan-shaped rotating disk 15.

[0045] After the arc plate 3 detaches, it can be moved into the cavity 4 and precisely moved above the U-shaped block 29. At this time, the third electric push rod 30 can be activated to control the U-shaped block 29 to rise, so that the two arc-shaped clamping blocks 32 correspond to a rotating core 10. Then, the two cylinders 31 can be activated simultaneously to drive the two arc-shaped clamping blocks 32 to clamp the rotating core 10, ensuring that the rotating core 10 is fixed and does not rotate. Then, the electric telescopic rod 5 is activated to separate the docking block 25 from the arc plate 3. At this time, the third electric push rod 30 can be activated 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 activated to perform a sharpening and maintenance operation on the end of the drill bit. During the sharpening and maintenance operation, the hole at the bottom of the cavity 4, which is aligned with the U-shaped block 29, allows for the setting of drill bits of different lengths. The rotating core 10 can be manually rotated and adjusted to ensure that the drill bit can be fully sharpened and maintained.

[0046] As can be seen from the above operation, by setting multiple arc plates 3 and moving the positions of multiple arc plates 3, one arc plate 3 can be used normally while another arc plate 3 can be maintained, thereby ensuring the continuity of drilling and processing, effectively guaranteeing work efficiency, and avoiding the impact of maintenance operations on work efficiency caused by a single arc plate 3.

[0047] The two electric telescopic rods 5 of this device have parts mounting plates 27 with several pipe clamping slots. These slots can be used to install relevant pipes, such as coolant spray pipes, negative pressure dust suction pipes, and blower pipes. This allows for flexible use during drilling operations. Furthermore, the telescopic movement of the two electric telescopic rods 5 enables the movement of several pipes, achieving a flexible and comprehensive usage effect. For example, the blower pipe can be moved to achieve a more comprehensive blowing operation, i.e., a comprehensive air drying effect.

[0048] Meanwhile, the workbench 34 of this device can switch the positions of the two bench vises 35, so that when one bench vise 35 is holding the part and corresponding to the work station, the other bench vise 35 is also holding the part and waiting. After drilling is completed, the next drilling operation can be carried out quickly, which effectively improves the drilling efficiency.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
