[0033] See Figures 1-6In this embodiment of the present invention, a drilling device for precision machining tools includes: a first rotary motor 1, a drill bit 2, a lifting seat 3, and a transverse module 4. The output end of the first rotary motor 1 is connected to the drill bit 2. The first rotary motor 1 is disposed on the front end face of the lifting seat 3, and the transverse module 4 is disposed on the rear end face of the lifting seat 3. The lifting seat 3 includes a first connecting plate 31, a first lead screw 32, a first slide block 33, and a second rotary motor 34. The first lead screw 32 is rotatably mounted on the front end face of the first connecting plate 31. The first slide block 33 has a threaded hole for threaded connection of the first lead screw 32. The output end of the second rotary motor 34 is connected to one end of the first lead screw 32 to drive the first lead screw 32 to rotate, thereby driving the first slide block 33 to move on the first lead screw 32. The first rotary motor 1 is mounted on the front end face of the first slide block 33 to drive the first rotary motor 1 to rise and fall. Module 4 includes a horizontal guide post 41, a first slider 42, a transmission belt 43, and a third rotary motor 44. The horizontal guide post 41 is disposed on the rear end face of the first connecting plate 31. The first slider 42 is slidably mounted on the horizontal guide post 41, and the front end face of the first slider 42 is mounted on the rear end face of the first connecting plate 31. The transmission belt 43 is mounted on the rear end face of the first slider 42 to drive the first slider 42 to move laterally. The transmission belt 43 includes a driving wheel, a driven wheel, and a belt. The belt is sleeved on the driving wheel and the driven wheel. The first slider 42 is provided with a clamping device mounted on the belt. The drive end of the third rotary motor 44 is connected to the driving wheel. The third rotary motor 44 drives the driving wheel to rotate back and forth through reciprocating motion, so that the first slider 42 on the belt moves back and forth in the lateral direction. The first slider 42 drives the first connecting plate 31 to move, so that the drill bit 2 can be adjusted in the lateral direction.

[0034] Specifically, the connection between the first slide block 33 and the first lead screw 32 is a threaded slider connection. The working principle of this embodiment is as follows: This drilling device, by setting a lifting seat 3 that can drive the drill bit 2 to move longitudinally and a transverse moving module 4 that can drive the drill bit 2 to move laterally, can flexibly adjust the drilling position during tool processing, making the drilling position adaptable to the processing requirements of tools of different sizes, thus enhancing its applicability.

[0035] like Figure 5 As shown, in another embodiment of this utility model, the first rotating motor 1 can be driven to lift and lower by setting an electric cylinder 6. The output end of the electric cylinder 6 faces downward and is installed on the front end face of the first connecting plate 31. The rear end face of the first slide block 33 is installed on the output end of the electric cylinder 6. When the electric cylinder 6 is energized, it can drive the first rotating motor 1 to lift and lower, thereby adjusting the height of the drill bit 2.

[0036] Further as Figures 1-4As shown in the embodiment of this utility model, the lifting seat 3 further includes two first guide blocks 35 and two first guide posts 36. Both first guide blocks 35 are disposed on the rear end face of the first slide 33, and the two first guide posts 36 are longitudinally mounted on the front end face of the first connecting plate 31. The two first guide blocks 35 are slidably mounted on the two first guide posts 36. The two first guide blocks 35 are evenly disposed on the rear end face of the first slide 33, for example, symmetrically mounted in the left-right direction. The connection methods between the first guide blocks 35 and the first slide 33 include, but are not limited to, threaded connections, snap-fit ​​connections, and tenon joints. The connection methods between the first guide posts 36 and the first connecting plate 31 include, but are not limited to, threaded connections, snap-fit ​​connections, and tenon joints. The first guide blocks 35 can be provided with guide holes, through which the first guide posts 36 pass, allowing the first guide blocks 35 to slide on the first guide posts 36. This not only restricts the rotation of the first slide 33 about the first lead screw 32, but also guides the first slide 33 during sliding.

[0037] Further as Figure 6 As shown in the embodiment of this utility model, the transverse module 4 further includes two second guide blocks 45 and two second guide posts 46. Both second guide blocks 45 are disposed on the rear end face of the first connecting plate 31, and the second guide posts 46 are arranged laterally on the rear end face of the first connecting plate 31. The two second guide blocks 45 are slidably mounted on the two second guide posts 46. The two second guide blocks 45 are evenly disposed on the rear end face of the first connecting plate 31, for example, symmetrically mounted in the vertical direction. The connection between the second guide blocks 45 and the first connecting plate 31 includes, but is not limited to, threaded connection, snap-fit ​​connection, and tenon joint. The second guide blocks 45 can be provided with guide holes, through which the second guide posts 46 pass, allowing the second guide blocks 45 to slide on the second guide posts 46, thus guiding the first connecting plate 31 during movement and ensuring stability. The transverse module 4 can be provided with two sets of support frames 7 for mounting the second guide posts 46 and the transmission belt 43. The connection between the two support frames 7 and the second guide posts 46 can be a threaded connection. The driving pulley and driven pulley of the transmission belt 43 are rotatably mounted on the support frame 7.

[0038] Further as Figure 1 and Figures 7-9As shown in the embodiment of this utility model, the lower end of the drill bit 2 is provided with a clamping member 5. The clamping member 5 includes a base 51, a first adjusting seat 52, a first screw 53, a first locking pin 54, a second adjusting seat 55, a second screw 56, and a second locking pin 57. The first adjusting seat 52 is installed on the upper end surface of the base 51, and the second adjusting seat 55 is installed on the upper end surface of the base 51. The first adjusting seat 52 and the second adjusting seat 55 are spaced apart to form a clamping groove 58. The first adjusting seat 52 has a first sliding groove 521, which connects to the clamping groove 58. The first locking pin 54 is slidably mounted on the first slide groove 521. The upper end face of the first adjusting seat 52 has a first threaded through hole 522, which connects to the first slide groove 521. The first screw 53 is threadedly connected to the first threaded through hole 522. The second adjusting seat 55 has a second slide groove 551. The second locking pin 57 is slidably mounted on the second slide groove 551. The upper end face of the second adjusting seat 55 has a second threaded through hole 552, which connects to the second slide groove 551. The second screw 56 is threadedly connected to the second threaded through hole 552. The first screw 53 and the second screw 56 can be internal hexagonal screws.

[0039] The working principle of this embodiment is as follows: the distance between the clamping tool can be adjusted by sliding the first clamping post 54 and the second clamping post 57. When adjusted to a suitable position, the first screw 53 and the second screw 56 are turned to restrict the sliding of the first clamping post 54 and the second clamping post 57 respectively, thereby completing the clamping of the tool to be processed and meeting the needs of tools of different sizes in actual processing.

[0040] Further as Figure 10 As shown in the embodiment of this utility model, the right side of the second locking post 57 is provided with an adjusting slope 571, and the front and rear ends of the second adjusting seat 55 near the second threaded through hole 552 are respectively provided with sliding holes 553. The second adjusting seat 55 is provided with a sliding rod 554, which passes through the sliding hole 553. The outer circular surface of the sliding rod 554 is tangent to the adjusting slope 571. The second screw 56 abuts against the sliding rod 554 to push the sliding rod 554 to move along the sliding hole 553. Specifically, the second locking post 57 slides to the second threaded through hole 552, so that the adjusting slope 571 is directly opposite the threaded through hole, and at the same time, the adjusting slope 571 is tangent to the sliding rod 554. The working principle of this embodiment is as follows: the operator rotates the second screw 56 to move it downward in the second threaded through hole 552, which drives the sliding rod 554 to slide in the sliding hole 553. The sliding rod 554 presses down on the adjusting slope 571. As the pressure of the adjusting slope 571 increases, the sliding rod 554 pressing down on the adjusting slope 571 can push the second locking pin 57 to slide in the direction of the sliding groove.

[0041] Further as Figure 10As shown, in this embodiment of the invention, the angle of the adjusting slope 571 is 20°-45°. When the adjusting slope 571 is 20°, the sliding speed of the second clamping pin 57 is the slowest, suitable for clamping in precision machining. When the adjusting slope 571 is 45°, the sliding speed of the second clamping pin 57 is the fastest, suitable for rough machining. In practical applications, rough drilling can be performed first, followed by precision drilling, to ensure machining accuracy.

[0042] Further as Figure 7 As shown in the embodiment of this utility model, the clamping member 5 is provided with at least two anti-slip rubber pads 59, which are installed on the outer surfaces of adjacent first clamping posts 54 and second clamping posts 57. Specifically, the connection between the anti-slip rubber pads 59 and the first clamping posts 54 includes, but is not limited to, adhesive bonding, threaded connection, etc. The anti-slip rubber pads 59 can be installed on the adjacent outer surfaces of the first clamping posts 54 and second clamping posts 57, and the anti-slip rubber pads 59 can increase the friction force, thus ensuring stability when clamping the tool.

[0043] Further as Figures 7-10 As shown, in this embodiment of the invention, the first adjusting seat 52 is integrally connected to the base 51, and the second adjusting seat 55 is integrally connected to the base 51. The first adjusting seat 52, the base 51, and the second adjusting seat 55 can be integrally machined by a milling machine or a machining center.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
