Description

Technical Field

[0001] This application relates to the technical field of automotive parts processing equipment, and in particular to an automatic drilling device for automotive half-shaft flanges. Background Technology

[0002] A half-shaft, also known as a drive shaft, is a solid shaft that connects the differential to the drive wheels and is used to transmit torque. Its inner end is typically connected to the half-shaft gear via a spline, while its outer end connects to the wheel hub. Depending on the specific structural design, the outer end can be directly connected to the wheel hub via a flange, or it can be first connected to the transmission components via a spline and then fixed to the wheel hub. During the manufacturing process of the half-shaft, the flange portion requires drilling.

[0003] In related technologies, such as Chinese patent CN216938494U, a radial drilling machine for machining holes in automotive parts is proposed. This radial drilling machine for machining holes in automotive parts includes a base, a column and a worktable disposed above the base, a cantilever disposed on the surface of the column, a spindle box disposed on the surface of the cantilever, and a spindle disposed below the spindle box. A spindle motor that is drivenly connected to the spindle is disposed on the top of the spindle box. A support rod is disposed on the side of the column away from the spindle. The top and bottom of the support rod are fixedly connected to an upper connecting seat and a lower connecting seat that are rotatably connected to the surface of the column, respectively. A cantilever lifting motor is disposed on the top of the column. A lifting screw that is drivenly connected to the cantilever is disposed between the cantilever lifting motor and the lower connecting seat and on the side of the column closer to the spindle.

[0004] The aforementioned technologies have the following drawbacks: When workers use the aforementioned radial drilling machine to drill holes in flanges, they need to customize molds with holes or manually mark lines on the flanges to facilitate the positioning of the flange holes. However, different flanges have different numbers of holes, which requires workers to customize corresponding molds for different flanges, making it inconvenient to determine the flange hole positions.

Detailed Implementation

[0017] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] This application discloses an automatic drilling device for automobile half-shaft flanges. (Refer to...) Figure 1 and Figure 2 The drilling device includes a drilling machine body 1, a worktable 2, a support platform 4, a rotating platform 3, a hole position adjustment mechanism 6, and a rotating mechanism 5.

[0019] The drill body 1 is fixed to the ground. The worktable 2 is fixedly connected to the drill body 1 and is located below the drill bit of the drill body 1. The support platform 4 is detachably connected to the worktable 2 by bolts. In this embodiment, the support platform 4 has a receiving cavity 41, a receiving cavity 42, and a receiving cavity 43, which are arranged sequentially along the direction close to the worktable 2.

The rotating column 31 is rotatably connected to the side wall of the receiving cavity 41, the receiving cavity 42, and the receiving cavity 43. The rotary table 3 is located directly below the drill bit of the drill body 1. To facilitate the installation of workpieces by the operator, a three-jaw chuck or a four-jaw chuck is detachably connected to the rotary table 3 by bolts. To improve the stability of the rotary table 3 when it stops rotating, a locking electromagnet is fixedly connected in the receiving cavity 43. An iron part for magnetic connection with the locking electromagnet is fixedly connected on the rotating column 31. A controller is provided on the outer wall of the support table 3, and the controller is electrically connected to the locking electromagnet.

[0020] Reference Figure 3 and Figure 4The rotating mechanism 5 includes a forward rotating assembly 51 and a reverse rotating assembly 52. ​​The forward rotating assembly 51 includes a forward rotating gear 511, a forward rotating rack 512, a rotating gear 513, a forward rotating pawl 514, a forward rotating ratchet 515, a transmission gear 516, and a transmission rack 517. The forward rotating gear 511 is located within the receiving cavity 42 and is coaxially and fixedly connected to the rotating column 31. A T-shaped groove is formed on the inner wall of the receiving cavity 42 away from the worktable 2. A slider 5121, matching the shape of the groove, is fixedly connected to the forward rotating rack 512. The slider 5121 slides along the groove, and the forward rotating rack 512 meshes with the forward rotating gear 511. The rotating gear 513 is rotatably connected to the inner wall of the receiving cavity 42 away from the worktable 2 and meshes with the forward rotating rack 512. The transmission gear 516 and transmission rack 517 are located in the receiving cavity 43, and the inner wall of the receiving cavity 43 is provided with a sliding groove along the position near or away from the cavity opening. The sliding groove is a T-shaped groove, and a sliding block that is slidably connected to the sliding groove is fixedly connected to the transmission rack 517. The transmission gear 516 is rotatably connected to the inner wall of the receiving cavity 43 and meshes with the transmission rack 517. The forward-rotating ratchet 515 is located in the receiving cavity 42. The forward-rotating ratchet 515 is coaxially fixedly connected to the transmission gear 516 and rotatably connected to the rotating gear 513. A rotating shaft is fixedly connected to the forward-rotating pawl 514, and the rotating shaft is rotatably connected to the rotating gear 513. The forward-rotating pawl 514 meshes with the forward-rotating ratchet 515. In order to improve the meshing stability of the forward rotating pawl 514 and the forward rotating ratchet 515, a torsion spring is sleeved on the rotating shaft. One end of the torsion spring is connected to the forward rotating pawl 514, and the other end is fixedly connected to the rotating gear 513. Under the action of the torsion spring, the forward rotating pawl 514 and the forward rotating ratchet 515 mesh.

[0021] Reference Figure 1 , Figure 4 and Figure 5A drive assembly 7 for sliding the transmission rack 517 is provided on the support platform 4. The drive assembly 7 includes a drive pedal 71, a drive rope 72, a drive block 73, a drive spring 74, and a sliding spring 75. The transmission rack 517 has a sliding groove 5172 along its length. The sliding groove 5172 is a T-shaped groove. The drive block 73 is shaped to fit the sliding groove 5172 and is slidably connected to it. The sliding spring 75 is located inside the sliding groove 5172, with one end fixedly connected to the drive block 73 and the other end fixedly connected to the end wall of the sliding groove 5172. Under the elastic force of the sliding spring 75, the side of the drive block 73 facing away from the sliding spring 75 abuts against the corresponding end wall of the sliding groove 5172. An electromagnet is fixedly connected to the end wall of the sliding groove 5172 where it abuts against the drive block 73. The drive block 73 is magnetically connected to the electromagnet, and the electromagnet is electrically connected to the controller. The drive pedal 71 includes a rotating section 711 and a fixed section 712. The fixed section 712 is fixedly connected to the ground with bolts. One side of the rotating section 711 is rotatably connected to the fixed section 712, and the other end extends inclined away from the ground. One end of the drive rope 72 is fixedly connected to the free end of the rotating section 711, and the other end passes through the door panel 44 and into the sliding groove 5172, where it is fixedly connected to the drive block 73. One end of the drive spring 74 is fixedly connected to the transmission rack 517, and the other end is fixedly connected to the end wall of the sliding groove 5172. Under the elastic force of the drive spring 74, the drive rope 72 is tensioned, and the free end of the rotating section 711 is spaced apart from the fixed section 712. To facilitate the rotation of the rotating section 711 to the position spaced apart from the fixed section 712, a spring is connected between the rotating section 711 and the fixed section 712.

[0022] The length of the sliding groove 5172 is greater than the distance the drive rope 72 moves when the rotating section 711 rotates to contact the fixed section 712. This makes it difficult for the operator to move the transmission rack 517 if they continue to step on the rotating section 711 after the electromagnet is de-energized. At the same time, the elastic force of the drive spring 74 is greater than that of the sliding spring 75, which further makes it difficult for the operator to move the transmission rack 517 if they continue to step on the rotating section 711 after the electromagnet is de-energized.

[0023] When the operator steps on the rotating section 711, the rotating section 711 rotates and drives the drive rope 72 to be tensioned so that the drive spring 74 is stretched. At the same time, the transmission rack 517 slides and drives the transmission gear 516 to rotate, so that the rotating gear 513 rotates in the forward direction under the action of the forward rotating pawl 514 and the forward rotating ratchet 515, which in turn drives the forward rotating rack 512 to slide and causes the forward rotating gear 511 to rotate, that is, the rotating table 3 rotates.

[0024] The reverse rotation assembly 52 is located within the receiving cavity 41. The reverse rotation assembly 52 includes a reverse gear 521, a first rotating gear 522, a second rotating gear 523, an abutment block 524, a reverse torsion spring, and a reverse rack 525. The first rotating gear 522 is rotatably connected to the inner wall of the receiving cavity 41 and is coaxially and fixedly connected to the rotating column 31. The second rotating gear 523 meshes with the first rotating gear 522 and is rotatably connected to the side wall of the receiving cavity 42, and is coaxially and fixedly connected to the reverse gear 521. A connecting groove 422, which is T-shaped, is formed on the inner wall of the accommodating cavity 42 near the worktable 2, extending towards or away from the opening of the accommodating cavity 42. One end of the reversing rack 525 is rotatably connected to a connecting block that matches the shape of the connecting groove 422. The connecting block is slidably connected to the connecting groove 422. One end of the reversing torsion spring is fixedly connected to the reversing rack 525, and the other end is fixedly connected to the connecting block. Under the elastic force of the reversing torsion spring, the reversing rack 525 rotates to a position where its engagement with the reversing gear 521 is disengaged. The abutment block 524 is fixedly connected to the side wall of the accommodating cavity 42. The abutment block 524 is a long strip, and its length direction is parallel to the length direction of the connecting groove 422. The abutment block 524 can abut against the toothed side of the reversing rack 525.

[0025] A sliding assembly 8 for driving the reversing rack 525 to slide is provided inside the receiving cavity 42. The sliding assembly 8 includes a sliding rope 81, a sliding pedal 82, sliding wheels 83, and a sliding spring 84. The reversing rack 525 has a connecting hole along its length. The sliding spring 84 is located in the connecting groove 422, and one end of the sliding spring 84 is fixedly connected to the end wall of the connecting groove 422, and the other end is fixedly connected to the connecting block. Multiple sliding wheels 83 are provided, and the sliding wheels 83 are rotatably connected to the side wall of the receiving cavity 41 near the worktable 2. In this embodiment, there are two sliding wheels 83, and the plane containing the axes of the two sliding wheels 83 is perpendicular to the length direction of the connecting groove 422. The sliding pedal 82 includes a rotating section 821 and a positioning section 822. The positioning section 822 is fixedly connected to the ground bolt. One side of the rotating section 821 is rotatably connected to the positioning section 822, and the other side extends obliquely towards the free end of the positioning section 822. One end of the sliding rope 81 is fixedly connected to the rotating section 821, and the other end passes through the door panel 44, around two sliding rollers 83, and then into the connecting hole, where it is fixedly connected to the end of the connecting hole away from the cavity opening 41. The elastic force of the sliding spring 84 is greater than that of the reverse torsion spring. One of the sliding rollers 83 is aligned with the connection position of the sliding rope 81 and the door panel 44 on the side away from the connecting groove 422, and the sliding rope 81 abuts against the side of the sliding roller 83 away from the door panel 44. The other sliding roller 83 is located on the side of the contact block 524 away from the reverse rack 525, and the sliding rope 81 abuts against the side of the sliding roller 83 near the door panel, so that when the sliding rope 81 is tensioned, the reverse rack 525 preferentially rotates to the position of meshing with the reverse gear 521.

[0026] Looking back Figure 2 and Figure 3The hole position adjustment mechanism 6 includes a hole dividing block 61, a hole dividing plate 62, and a hole dividing block detection element. The hole dividing plate 62 is fixedly connected to the forward rotating rack 512. The hole dividing plate 62 has an adjustment groove 621 along its length direction. Multiple adjustment blocks 611 are provided on the hole dividing plate 62, and the multiple adjustment blocks 611 are arranged sequentially along the length direction of the hole dividing plate 62. The adjustment blocks 611 are all "I" shaped and are engaged with the two side walls of the adjustment groove 621 and slidably connected to the adjustment groove 621. Multiple hole dividing blocks 61 are provided, and one hole dividing block 61 is connected to one adjustment block 611. The adjustment block 611 and the hole dividing block 61 are detachably connected. In this embodiment, the detachable connection between the hole dividing block 61 and the adjustment block 611 is as follows: the hole dividing block 61 is connected to a locking block. The locking block has a quadrilateral cross section, and the adjustment block 611 has a locking groove that engages with the locking block. The dividing block 61 located at one end is a fixed dividing block, which is fixedly connected to the dividing plate 62. One of the dividing blocks 61 is a positioning dividing block, with a protrusion fixedly connected to it. The dividing plate 62 has a groove, and the protrusion 612 engages with the groove. The dividing block detection element is an infrared sensor. The transmitting and receiving ends of the infrared sensor are fixedly connected to the side wall of the accommodating cavity 42 and are located on both sides of the dividing plate 62. The infrared sensor is electrically connected to the controller to control the activation and closure of the locking electromagnet. The dividing plate 62 is provided with an adjustment assembly 64 for adjusting the distance between the dividing blocks 61. The adjustment assembly 64 includes multiple adjustment rods 641, which are arranged in pairs. Multiple sets of adjustment rods 641 are arranged sequentially along the length of the adjustment groove 621. Two adjustment rods 641 in the same group are arranged crosswise and rotatably connected by a rotating shaft to form an X-shaped telescopic structure. The adjustment rods 641 of adjacent X-shaped telescopic structures are rotatably connected by a pin. The rotation axis of the adjustment component 64 corresponds one-to-one with the adjustment block 611, and the rotation axis is rotatably connected to the corresponding adjustment block 611.

[0027] The distance between the positioning and fixed dividing hole blocks is the same as the distance the forward gear 511 moves when it rotates one revolution, driving the forward rack 512 to move. When the operator needs to adjust the number of dividing hole blocks 61, the positioning dividing hole block is removed, and then the adjusting block 611 is pressed so that the number of positioning dividing hole blocks, fixed dividing hole blocks, and the dividing hole blocks 61 between them is equal to the number of holes on the flange plus one.

[0028] The implementation principle of the automatic drilling device for automobile half-shaft flanges in this application embodiment is as follows: The operator steps on the rotating section 711, causing it to rotate and tension the drive rope 72, thus stretching the drive spring 74. Simultaneously, the transmission rack 517 slides, driving the transmission gear 516 to rotate. This causes the rotating gear 513 to rotate forward under the action of the forward pawl 514 and the forward ratchet 515, further driving the forward rack 512 to slide and causing the forward gear 511 to rotate, i.e., the rotating table 3 to rotate. At this time, the hole-dividing plate 62 moves with the forward rack 512. When the hole-dividing block 61 moves between the transmitting and receiving ends of the hole-dividing block detection element, the hole-dividing block detection element emits an electrical signal to the electromagnet and the locking electromagnet, causing the electromagnet to... When the magnet stops operating and the locking electromagnet operates, the transmission rack 517 is difficult to move further, i.e., the rotary table 3 stops rotating. The drill body 1 is controlled to complete the drilling of the flange. After drilling is completed, the operator controls the controller to close the locking electromagnet and activate the electromagnet. At this time, the electromagnet attracts the drive block 73, so that the drive block 73 can move and drive the transmission rack 517 to move, so that the operator can process other holes. After the flange is processed, the sliding pedal 82 is pressed to make the reverse rack 525 rotate to the position of meshing with the reverse gear 521. Then the sliding pedal 82 is pressed again to make the reverse rack 525 start to slide and make the reverse gear 521 start to reverse until the rotary table 3 is reset.
