Description

Technical Field

[0001] The invention relates to the technical field of drilling and tapping of aluminum die castings, and in particular to a multi-axis drilling and tapping integrated machine for producing aluminum die castings. Background Art

[0002] In the production process of aluminum die castings, drilling and tapping are common processing methods with a wide range of applications. In order to be more versatile, the current drilling and tapping integrated machine generally uses a fixture to clamp the aluminum die casting to be processed on the processing platform, so as to drill and tap the workpiece to be processed;

[0003] However, due to the different specifications and shapes of existing aluminum die-castings, it is necessary to perform drilling and tapping operations on multiple sides of the die-castings. Due to the irregular shapes of aluminum die-castings, the clamps required for clamping need to be replaced, and manual replacement of the clamps and adjustment of the angles of the die-castings are required to switch clamping. In addition, general drilling and tapping operations require the use of multiple sets of linked drill bits simultaneously. When switching between drilling and tapping on different sides of the aluminum die-castings, the corresponding drill bits need to perform avoidance operations, and the existing drill avoidance operations can only be performed by manually finding the position and then determining the position. When avoidance is impossible, only multiple drilling and tapping operations can be performed, resulting in poor work efficiency. For this reason, we propose a multi-axis drilling and tapping integrated machine for the production of aluminum die-castings. Summary of the invention

[0017] Compared with the prior art, the beneficial effects that the present invention can achieve are:

[0018] 1. By setting the driving mechanism and the tapping mechanism, the present invention can perform automatic clamping stability and self-adjustment of the angle position orientation of the aluminum die-casting parts, avoiding the problems of low efficiency in manual adjustment operations and the inconvenience of clamping the special-shaped die-casting parts to make the corresponding surface face upward. It can perform synchronous drilling and tapping operations on one side of the aluminum die-casting part and self-avoidance operations during the drilling and tapping operations, avoiding the problem of low efficiency in multiple drilling and tapping operations required for one side of the die-casting part when synchronous drilling and tapping cannot be avoided. Moreover, it has a good effect in adapting to different specifications of aluminum die-casting parts, without the need to replace multiple specifications of fixtures for combined use, and further improves the working efficiency of processing and product changeover.

[0019] 2. By setting up a driving mechanism in the present invention, the first electric push rod drives the driving gear to be upwardly extruded and obliquely inserted and engaged on the side surface of the first rack or the second rack. The first detection block detects the distance position of the driving gear to determine whether it reaches the specified position. Among them, the driving gear is engaged at the intersecting position of the first rack or the second rack. The rotation of the driving gear can drive the two groups of the first racks or the second racks to be synchronously engaged and move them. In addition, the driving gear is only engaged at the side position of the first rack or the second rack. When the driving gear rotates to drive the corresponding engaged first rack and second rack to move, in this way, a single set of sliders and two sets of sliders at different positions can be driven to slide by a single first motor, effectively reducing the setting of driving motors, reducing energy consumption and lowering the required cost at the same time.

[0020] 3. By setting up a tapping mechanism in the present invention, the sixth electric push rod at the corresponding position pushes the block to slide inside the cavity and is clamped inside the circular groove on the side surface of the corresponding drill rod to limit its position. The fifth electric push rod pulls the adjusting plate to move upward inside the matching cavity. The matching cavity can drive the limited drill rod to move upward. The synchronous telescopic rod contracts and the universal joint performs universal rotation and cooperation to complete the avoidance effect of the drill rod at the corresponding position. In this way, when drilling and tapping different surfaces of the die-casting part, the drill rod at the corresponding position can be actively avoided, and a one-time operation can be realized when drilling and tapping one surface of the die-casting part, improving work efficiency.

[0021] 4. By setting up a clamping module in the present invention, when the clamping block clamps the die-casting part, the cooperating wheel is extruded, causing the movable block to slide inside the installation groove and squeeze the second spring to deform, so that the clamping block clamps on the side surface of the die-casting part. At the same time, the cooperating wheel elastically squeezes on the side surface of the die-casting part to ensure stable clamping;

[0022] In addition, when the clamping block supports the die-casting part, the side surface of the die-casting part squeezes on the side surface of the cooperating wheel to make it rotate. At the same time, the movable block is extruded and limited inside the installation groove to limit the cooperating wheel, so that it supports and guides the die-casting part. In this way, both the stability of clamping the die-casting part and the stable support when adjusting the angle of the die-casting part are ensured.

[0023] 5. By setting up an auxiliary module in the present invention, when the drill rod drills and taps, first, the detection rod contacts the side surface of the die-casting part and squeezes the third spring to deform. The second detection block detects the distance of the detection rod to judge whether each drill rod reaches the specified position. When the sixth electric push rod pushes the block, the block is also clamped inside the circular groove on the side surface of the detection rod to limit its position. When the fifth electric push rod pulls the adjusting plate, the corresponding drill rod and the detection rod are both pulled upward by it to complete the avoidance operation, so as to ensure that the position is accurate and there is no dislocation during drilling and tapping.

[0024] 6. By arranging the third electric push rod and its peripheral components, when the third electric push rod is pushed to the bottom wall of the sliding cavity, it can brake and position the slider, ensuring the accurate position of the subsequent meshing and docking of the first tooth rod and the second tooth rod with the driving gear. The second electric push rod pushes and pulls the mounting frame to lift, and the second motor drives the cooperation block to rotate, which can drive the fourth electric push rod to rotate and adjust. The fourth electric push rod can push and pull the electric turntable to extend and retract, and the electric turntable can drive the electric gripper to rotate by an angle. Cooperating with the driven sliding of the slider, it realizes the four-way driving and position adjustment operation of the electric gripper, so that the electric gripper can cooperate in multiple directions to clamp and adjust the position of the die-casting part and other operations.

A driving mechanism 3 that can drive and clamp the aluminum die-casting is provided on the upper side of the body cabinet 1. A tapping mechanism 4 that can perform multiple groups of linkage drilling and tapping is provided on the side of the axial lifting assembly 13.

[0039] The drive mechanism 3 can be used to perform multi-axial combination and individual drive operations, and can reduce the number of drive components, reduce energy consumption and simplify the drive program settings;

[0040] like Figures 1 to 6 As shown, the driving mechanism 3 includes an installation cavity 31 opened inside the body cabinet 1, a first motor 311 is arranged on the bottom wall of the installation cavity 31 and the first motor 311 is movably arranged inside the body cabinet 1, a connecting rod 312 is fixedly installed at the output end of the first motor 311 and the connecting rod 312 is arranged inside the installation cavity 31, the connecting rod 312 is a spline cylindrical rod with an I-shaped cross section, a driving gear 314 is movably sleeved on the side of the connecting rod 312 and the driving gear 314 is arranged inside the installation cavity 31, the driving gear 314 is a circular ring gear with a spline shape on the inside and a bevel on the outside, and a first motor 311 is fixedly connected to the side of the connecting rod 312 The spring 313 and the first spring 313 are attached to the bottom side of the driving gear 314, the first spring 313 is movably sleeved on the side of the connecting rod 312, and the first electric push rod 315 is fixedly installed on the lower side of the first motor 311 and the first electric push rod 315 is fixedly arranged in the inner position of the body cabinet 1, and the first electric push rod 315 is reinforced and fixed to the side of the first motor 311 through a connecting piece; specifically, the first electric push rod 315 can drive the first motor 311 to perform lifting operations, and the first motor 311 can drive the connecting rod 312 to constrain the driving gear 314 to rotate, and the first spring 313 can elastically support the driving gear 314;

[0041] The inner wall of the installation cavity 31 is equidistantly and staggeredly provided with four groups of movable cavities 32, and the four groups of movable cavities 32 penetrate and extend to the inside of the machine body cabinet 1. The movable cavity 32 is a rectangular cavity. Inside the machine body cabinet 1, two groups of first toothed rods 321 are mirror-image and staggeredly arranged corresponding to the position of the driving gear 314, and the two groups of first toothed rods 321 are respectively movably installed inside the corresponding movable cavities 32. The two groups of first toothed rods 321 are staggered at a half-distance. Inside the machine body cabinet 1, two groups of second toothed rods 322 are mirror-image and staggeredly arranged corresponding to the position of the driving gear 314, and the two groups of second toothed rods 322 are respectively movably installed inside the corresponding movable cavities 32. The two groups of second toothed rods 322 are staggered at a half-distance. The first toothed rod 321 and the second toothed rod 322 are rectangular rods with serrated sides. The first toothed rod 321 and the second toothed rod 322 are vertically arranged. A first detection block 316 is arranged on the top wall of the installation cavity 31. The first detection block 316 is a distance sensor (not limited here, and a sensor that can detect medium and long distances is sufficient). The widths of the first toothed rod 321 and the second toothed rod 322 are twice that of the driving gear 314. Specifically, the first electric push rod 315 drives the driving gear 314 to move upward and approach the side position of the second toothed rod 322 or the first toothed rod 321. At the same time, the driving gear 314 is squeezed to slightly deform the first spring 313 and slide slightly, and the first motor 311 rotates slowly accordingly, so that the driving gear 314 is obliquely inserted and engaged with the side of the first toothed rod 321 or the second toothed rod 322.

In addition, the driving gear 314 is only engaged at the side position of the first toothed rod 321 or the second toothed rod 322, and the rotation of the driving gear 314 only drives the corresponding engaged first toothed rod 321 and second toothed rod 322 to move;

[0042] On the upper side of the machine body cabinet 1, sliding cavities 33 are equidistantly arranged in a circumferential array corresponding to the positions of the first tooth bar 321 and the second tooth bar 322. The sliding cavities 33 only penetrate through the machine body cabinet 1 and pass through the inside of the moving cavity 32. The sliding cavities 33 are rectangular cavities with a cross-shaped cross-section. Inside the sliding cavities 33, sliding blocks 331 are movably installed. The sliding blocks 331 are cross-shaped blocks with rectangular grooves on the sides. Inside the sliding blocks 331, battery packs 332 are fixedly installed, and the battery packs 332 are externally connected to the power connection ports through wires.

On the upper side of the second electric push rod 333, a mounting frame 34 is fixedly installed, and the output end of the second electric push rod 333 is strengthened and fixed through a connecting piece. The mounting frame 34 is a "C" - shaped frame. On the side of the mounting frame 34, a matching block 35 is arranged, and the matching block 35 is rotatably installed through the side of the mounting frame 34. The matching block 35 is a cross-shaped rectangular block. On the side of the mounting frame 34, a second motor 36 is fixedly installed, and the output end of the second motor 36 penetrates through the mounting frame 34 and is fixedly connected to the side of the matching block 35. On the side of the matching block 35, a fourth electric push rod 37 is fixedly installed, and the fourth electric push rod 37 is strengthened and fixed on the side of the matching block 35 through a connecting piece. On the side of the fourth electric push rod 37, an electric rotating platform 38 is fixedly installed, and the electric rotating platform 38 is strengthened and fixed at the conveying end of the matching block 35 through a connecting piece. On the side of the electric rotating platform 38, a clamping module 5 is arranged; specifically, the sliding block 331 can slide inside the sliding cavity 33 under the pulling of the first tooth bar 321 and the second tooth bar 322. Synchronously, the sliding block 331 can push and pull the protective plate 335 to deform for protection. Through the arranged battery pack 332, power supply operations can be carried out on the third electric push rod 334 and the second electric push rod 333. The output end of the third electric push rod 334 pushes and presses against the bottom wall of the sliding cavity 33 to brake and position the sliding block 331. The second electric push rod 333 can push and pull the mounting frame 34 for lifting and lowering. The second motor 36 drives the matching block 35 to rotate, which can drive the fourth electric push rod 37 for rotational adjustment. The fourth electric push rod 37 can push and pull the electric rotating platform 38 for telescoping. The electric rotating platform 38 can drive the clamping module 5 to rotate by an angle, thus realizing the four-way driving and position adjustment operation of the clamping module 5;

[0043] Through the arranged clamping module 5, effective clamping and auxiliary support and guiding effects on the aluminum die-casting parts can be realized;

[0044] Such as Figure 6 And Figure 7As shown, the clamping module 5 includes an electric gripper 51 fixedly installed on the side of the electric turntable 38, and the electric gripper 51 is strengthened and fixed through a connecting member. A clamping block 52 is arranged mirror-symmetrically on the side of the electric gripper 51. The clamping block 52 is a "C"-shaped block. The clamping block 52 can be driven by the electric gripper 51 to perform clamping and loosening operations. Mounting grooves 53 penetrating through it are symmetrically formed on the side of the clamping block 52. The mounting grooves 53 are rectangular grooves. An active block 54 is movably installed inside the mounting grooves 53 close to the clamping block 52. The active block 54 is a rectangular block with a circular hole formed on its side.

A mating wheel 56 is movably arranged inside the clamping block 52, and the mating wheel 56 is rotatably installed on the side of the active block 54. The mating wheel 56 is a cross-shaped wheel made of wear-resistant rubber material. Specifically, when the clamping block 52 clamps the die-casting part, the mating wheel 56 is squeezed, causing the active block 54 to slide inside the mounting groove 53 and squeeze the second spring 55 to deform, so that the clamping block 52 clamps on the side of the die-casting part. At the same time, the mating wheel 56 elastically squeezes on the side of the die-casting part to ensure stable clamping. In addition, when the clamping block 52 supports the die-casting part, the side of the die-casting part squeezes on the side of the mating wheel 56 to make it rotate. At the same time, the active block 54 is squeezed and limited inside the mounting groove 53 to make the mating wheel 56 support and guide the die-casting part.

[0045] Through the provided tapping mechanism 4, the die-casting part can be synchronously drilled and tapped, and it can self-avoid the die-casting part.

The synchronous belt 44 is an "O"-shaped belt with a spline shape on the inner side. A third motor 45 is fixedly installed on the upper side of the driving frame 41, and the output end of the third motor 45 penetrates through the driving frame 41 and is fixedly installed at the side position of a group of driving blocks 43. A drill rod 46 is arranged at the position corresponding to the driving block 43 on the lower side of the driving frame 41, and the drill rod 46 penetrates through the driving frame 41 to reach its inner side position. The drill rod 46 is a convex-shaped cylindrical rod with an annular groove opened on the side. Universal joints 47 are respectively fixedly installed on the sides of the driving block 43 and the drill rod 46 close to each other. An expansion link 48 is fixedly connected between the universal joints 47. The expansion link 48 can perform self-expansion and contraction operations under external force. Specifically, the third motor 45 drives the driving block 43 to rotate. Through the transmission of the universal joints 47 and the expansion link 48, the drill rod 46 can be driven to perform rotary drilling and tapping operations. In addition, the provided synchronous belt 44 can synchronously drive other driving blocks 43 to rotate, ensuring that all drill rods 46 perform drilling and tapping operations.

A sixth electric push rod 495 is fixedly installed on the side of the clamping block 494, and the sixth electric push rod 495 is fixedly arranged on the side of the adjusting plate 491. An auxiliary module 6 is arranged at the position corresponding to the drill rod 46 on the lower side of the driving frame 41. Specifically, the sixth electric push rod 495 arranged at the corresponding position pushes the clamping block 494 to slide inside the opening cavity 493 and be clamped inside the annular groove on the side of the corresponding drill rod 46 to limit its position. The fifth electric push rod 492 pulls the adjusting plate 491 to move upward inside the fitting cavity 49, so that the fitting cavity 49 can drive the limited drill rod 46 to move upward, and the expansion link 48 contracts synchronously while the universal joints 47 perform universal rotation cooperation to complete the avoidance effect of the drill rod 46 at the corresponding position.

[0048] The auxiliary module 6 can play an auxiliary detection role during drilling and tapping to ensure that the drilling and tapping will not be misaligned;

[0049] Such as Figures 9 to 11 As shown, the auxiliary module 6 includes slots 61 equidistantly opened on the side of the adjusting plate 491 corresponding to the position of the cavity 493, and the slots 61 penetrate through the driving frame 41 to its inner side. The slots 61 are cylindrical slots. A detection rod 62 is movably installed inside the slots 61, and a circular ring groove is opened on the side of the detection rod 62 corresponding to the position of the cavity 493. The detection rod 62 is a "T"-shaped rod. A third spring 63 is fixedly connected between the side of the detection rod 62 and the driving frame 41, and the third spring 63 is movably sleeved on the side of the detection rod 62. A second detection block 64 is fixedly installed on the inner side of the driving frame 41 corresponding to the position of the detection rod 62. The second detection block 64 is a distance sensor (not limited here, as long as it can detect medium and long distances). Specifically, when the drill rod 46 drills and taps, first, the set detection rod 62 contacts the side of the die-casting part and squeezes the third spring 63 to deform. The distance of the detection rod 62 is detected by the second detection block 64 and fed back to the external controller. The controller can judge whether the corresponding positions of each drill rod 46 reach the specified positions according to the distance. In addition, when the sixth electric push rod 495 pushes the block 494, the block 494 is also clamped inside the circular ring groove on the side of the detection rod 62 at the corresponding position to limit its position. When the fifth electric push rod 492 pulls the adjusting plate 491, the corresponding drill rod 46 and the detection rod 62 are both pulled upward to complete the avoidance operation.

[0050] Working principle:

[0051] Before use: Select the program according to the corresponding aluminum die-casting part, place the die-casting part on the material station on the upper side of the machine body cabinet 1, and run the machine for use;

[0052] During use: In the first step, the first electric push rod 315 pushes the first motor 311 upward. The first motor 311 slightly drives the driving gear 314 to rotate, so that the driving gear 314 is obliquely inserted and engaged with the side position of the corresponding first tooth bar 321 or the second tooth bar 322. The first detection block 316 is used to detect whether the driving gear 314 reaches the specified position. The first motor 311 drives the driving gear 314 to engage with the first tooth bar 321 or the second tooth bar 322, so that the two groups of sliders 331 at the corresponding position move synchronously or the single group of the first motor 311 moves. After reaching the specified position, the third electric push rod 334 pushes to the bottom wall of the sliding cavity 33 to limit and fix the position of the slider 331. Subsequently, the second electric push rod 333, the second motor 36, the fourth electric push rod 37 and the electric turntable 38 control the electric gripper 51 to perform four-axis movement to a suitable position. The electric gripper 51 controls the clamping block 52 to clamp the die-casting part. Among them, the mating wheel 56 is squeezed and slides to fit on the side of the die-casting part to ensure stable friction. The clamping block 52 clamps the side of the die-casting part at the same time. Subsequently, the first tooth bar 321 or the second tooth bar 322 at another position is driven to make the clamping block 52 at the corresponding position clamp the side of the die-casting part, completing the stable clamping of the four sides of the die-casting part;

[0053] In the second step, the driving frame 41 is transferred to the corresponding position by the first axial electric slide 11, the second axial electric slide 12 and the axial lifting assembly 13 for drilling and tapping operations. Before synchronous drilling and tapping, the sixth electric push rod 495 pushes the clamping block 494 to be clamped on the side positions of the corresponding drill rod 46 and the detection rod 62. The fifth electric push rod 492 pulls the adjusting plate 491 to drive the clamped drill rod 46 and the detection rod 62 to move upward synchronously through the synchronous belt 44, performing an avoidance operation on the die-casting part. The telescopic rod 48 adaptively contracts to cooperate with the upward movement of the drill rod 46. The third motor 45 drives the driving block 43 to rotate. Under the synchronization of the synchronous belt 44, the drill rod 46 is driven to rotate synchronously through the universal joint 47 and the telescopic rod 48. The axial lifting assembly 13 pushes the driving frame 41 downward for drilling and tapping. Among them, the detection rod 62 first contacts the side of the die-casting part and is squeezed to deform the third spring 63. The second detection block 64 detects the distance of the detection rod 62 to judge whether it corresponds to the specified position. Subsequently, after the drill rod 46 performs drilling and tapping operations on the die-casting part, the driving frame 41 is transferred and reset;

[0054] In the third step, after drilling and tapping are completed on one side of the die-casting part, the clamping blocks 52 on both sides of the die-casting part are loosened. The electric gripper 51 is driven to move slightly backward for avoidance. The clamping blocks 52 on the other two sides clamp the die-casting part. The electric gripper 51 is rotated by the electric turntable 38 to swing and adjust the position of the die-casting part. Synchronously, the other two groups of electric grippers 51 are driven to cooperate so that the outer sides of the clamping blocks 52 are attached to the side of the die-casting part. At this time, the mating wheel 56 is attached to the side of the die-casting part and rolls to support and guide it, ensuring the stability of the die-casting part during position adjustment. After the adjustment is completed, the clamping blocks 52 on the four sides of the die-casting part are clamped and fixed in the same way;

[0055] Step 4: Subsequently, perform the same operation to drill and tap the die-cast part. Repeating the above operation can complete the drilling and tapping operations on multiple sides of the die-cast part without manual adjustment of the position.

[0056] After use: The set tapping mechanism 4 resets, and the set driving mechanism 3 places the die-cast part on the upper side of the machine cabinet 1 to complete the reset. After removing the die-cast part, perform the power-off cleaning operation.

[0057] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge of those skilled in the art without departing from the gist of the present invention.
