Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, specifically to an adaptive mounting base for an automotive wheel hub compression molding mechanism. Background Technology

[0002] The wheel hub is the part of the wheel where the axle is mounted. Wheel hubs can be divided into steel hubs and alloy hubs according to their material. The main advantage of steel hubs is their simple manufacturing process, generally using casting, resulting in relatively low cost. They also have strong resistance to metal fatigue. However, they are heavy, have high inertial drag, poor heat dissipation, and are very prone to rust. Alloy hubs can overcome these problems, offering advantages such as light weight, low inertial drag, high manufacturing precision, minimal deformation at high speeds, and low inertial drag. Alloy hubs are mostly cast using a compression molding method. This involves placing the raw material into a mold cavity at a molding temperature, then closing the mold and applying pressure to shape and solidify it. The core component of the compression molding mechanism is the mold core, or mold insert.

[0003] Chinese invention patent CN202010142940.X discloses a universal automatic cleaning measuring platform base for wheel hub processing. It includes a base 1, with two support blocks 2 fixedly connected to both the left and right sides of the top of the base 1. Each support block 2 is hexagonal prism in shape. The two support blocks 2 on the front and back are identical and symmetrical, as are the two support blocks 2 on the left and right sides. Each support block 2 has an internal threaded hole on the side away from the dedicated mandrel 4. A left fixing plate 3 is fixedly connected to the top of the base 1, and a right fixing plate 5 is fixedly connected to the top of the base 1 to the right of the left fixing plate 3. The left and right fixing plates 3 and 5 are identical and symmetrical. All plates 5 are arc-shaped with their centers at the same point. The left fixed plate 3 and the right fixed plate 5 are located between four support blocks 2. Each of the four support blocks 2 has five air outlets 7 on its top. The five air outlets 7 on the top of the same support block 2 are evenly and equidistantly distributed on the top of the support block 2. Each of the four support blocks 2 has a fixed anti-slip buffer pad 8. By setting the support blocks 2, the hub can be supported by four support blocks 2. Furthermore, the support blocks 2 have an internal threaded hole on the side away from the special spindle 4. The internal threaded hole can be used to connect an external compressed air pipe, which is connected to the air outlet of the air pump.

[0004] However, to press-mold different models and specifications of wheel hubs, different models and specifications of mold cores are required. But the mounting base used to fix the mold core in the existing automotive wheel hub pressing and molding mechanism is also bound to the mold core, and does not have the adaptability to match mold cores of different sizes and specifications.

A return spring is disposed within the mounting base body, one end of the return spring is connected to the mounting base body, and the other end of the return spring is connected to the movable seat.

[0018] The present invention has the following beneficial effects:

[0019] 1. This self-adaptive mounting base for automotive wheel hub compression molding mechanisms, compared to traditional mounting bases, utilizes three sets of mounting mechanisms (first, second, and third) to adapt to different models and specifications of mold cores. This simplifies production, eliminates the need for binding the mounting base and mold core, and reduces operating costs. First, a drive assembly rotates three lead screws, which in turn move three grippers inward synchronously, clamping and fixing the mold core at the center of the mounting base body. It also features a calibration function; when placing the mold core into the mounting base body, there is no need to specifically align it to the center point of the mounting base body, as the three grippers automatically push the mold core to the center position during the pushing process.

[0020] 2. This adaptive mounting base for automotive wheel hub compression molding mechanism, after the three grippers hold and fix the mold core in position, also has a second mounting mechanism to further secure the mold core. Through the synchronous operation of three electric push rods, the three hooks can be driven downwards to engage with the surface of the mold core using the lever principle, thereby further reinforcing the mold core.

[0021] 3. This adaptive mounting base for automotive wheel hub compression molding mechanism, after the three hooks engage with the surface of the mold core, the three electric push rods extend upwards, causing the three hooks to continue to rotate downwards, thus pressing the mold core and the movable seat downwards. The movable seat, through the transmission action of several racks and pinions and several third spur gears, causes the three locking blocks to move upwards synchronously and engage with three of the slots on the three grippers, further fixing the position of the three grippers.

[0022] 4. This adaptive mounting base for automotive wheel hub compression molding mechanisms features three grippers, three hooks, and three locking blocks for fixing the mold core. These components are equidistantly distributed around the midpoint of the mounting base body, forming an equilateral triangle. This ensures maximum stability. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] Please see Figures 1-6 This embodiment discloses an adaptive mounting base for an automobile wheel hub compression molding mechanism, including a mounting base body 1 and a mold core 2 disposed in the mounting base body 1. A first mounting mechanism 3 is provided in the mounting base body 1 for fixing the mold core 2. The first mounting mechanism 3 includes a drive component 5 and several clamping components 4.

[0033] The clamping assembly 4 includes a lead screw 401 rotatably disposed within the mounting base body 1, and a gripper 402 slidably disposed within the mounting base body 1, with the gripper 402 threadedly connected to the lead screw 401.

[0034] The drive assembly 5 is connected to several lead screws 401 to drive them to rotate, thereby driving several grippers 402 to move synchronously to calibrate and fix the mold core 2;

[0035] A movable seat 101 is slidably disposed inside the mounting base body 1, and the mold core 2 is disposed on the movable seat 101. A reset spring 102 is disposed inside the mounting base body 1. One end of the reset spring 102 is connected to the mounting base body 1, and the other end of the reset spring 102 is connected to the movable seat 101.

[0036] The clamping assembly 4 also includes a force sensor 403 disposed on the gripper 402.

[0037] The movable seat 101 slides up and down along the inner wall of the mounting base body 1 and is elastically connected to the bottom wall of the mounting base body 1 via a return spring 102. The mold core 2 is placed on the movable seat 101 and is cylindrical. A first mounting mechanism 3 is provided inside the mounting base body 1 for adaptive mounting of the mold core 2.

[0038] The first mounting mechanism 3 includes a drive assembly 5 and three clamping assemblies 4, which are arranged in a ring at equal intervals within the mounting base body 1. Three lead screws 401 are rotatably mounted at equal intervals on the inner wall of the mounting base body 1, and each of the three lead screws 401 is threaded with a jaw 402, which slides along the inner wall of the mounting base body 1.

[0039] By driving the three lead screws 401 to rotate synchronously through the drive assembly 5, the three grippers 402 can move synchronously towards the inside of the mounting base body 1, thereby clamping and fixing the mold core 2 inside the mounting base body 1. Furthermore, force sensors 403 are installed on each of the three lead screws 401. When the three grippers 402 clamp and fix the mold core 2, the three force sensors 403 will detect a force signal exceeding the pushing force threshold.

[0040] Furthermore, the three grippers 402 also have a calibration function. When placing the mold core 2, it is not necessary to align it with the midpoint of the mounting base body 1. Simply put the mold core 2 down, and the mold core 2 can be calibrated to the midpoint of the mounting base body 1 under the synchronous push of the three grippers 402.

[0041] The clamping component 4 is set to have three parts, also because of the force balance of the triangle.

[0042] Further, please refer to Figures 2-6 The drive assembly 5 includes several first bevel gears 501, which are respectively disposed on several lead screws 401. A rotating ring 502 is rotatably disposed inside the mounting base body 1. A second bevel gear 503 is disposed on the rotating ring 502, and the second bevel gear 503 meshes with several first bevel gears 501.

[0043] The drive assembly 5 also includes a motor 504 disposed in the mounting base body 1. The motor 504 is provided with a first spur gear 505, and the rotating ring 502 is provided with a second spur gear 506, and the second spur gear 506 meshes with the first spur gear 505.

[0044] Each of the three lead screws 401 is fixed with a first bevel gear 501. A rotating ring 502 is rotatably mounted on the bottom wall of the mounting base body 1, and a second bevel gear 503 is fixed on the rotating ring 502. The second bevel gear 503 meshes with all three first bevel gears 501. A motor 504 is fixed on the bottom wall of the mounting base body 1, and a first spur gear 505 is fixed on the motor 504. A second spur gear 506 is fixed on the rotating ring 502, and the first spur gear 505 meshes with the second spur gear 506.

[0045] The operation of motor 504 can drive the first spur gear 505 to rotate, which in turn drives the second spur gear 506 and the rotating ring 502 to rotate, which in turn drives the second bevel gear 503 and the three first bevel gears 501 to rotate, which in turn drives the three lead screws 401 to rotate.

[0046] Example 3

[0047] Further, please refer to Figures 2-6 The mounting base body 1 is also provided with several second mounting mechanisms 6 for fixing the mold core 2. The second mounting mechanism 6 includes a first support 601 provided in the mounting base body 1, and a hook 602 is movably hinged on the first support 601 through a hinge shaft.

[0048] The second installation mechanism 6 also includes a connector 603 disposed on the hook 602, an electric push rod 604 disposed inside the installation base body 1, a sliding shaft 605 disposed on the electric push rod 604, and the sliding shaft 605 is slidably disposed on the connector 603.

[0049] The mounting base body 1 includes three equidistant second mounting mechanisms 6 for reinforcing the mold core 2. A first support 601 is fixed to the bottom wall of the mounting base body 1. A hook 602 is hinged to the first support 601 via a hinge shaft. An electric push rod 604 is also fixed to the bottom wall of the mounting base body 1. A sliding shaft 605 is fixed to the output shaft of the electric push rod 604. A connecting piece 603 is fixed to the side end of the hook 602. The connecting piece 603 consists of two plates with elliptical grooves. The sliding shaft 605 can slide along the two grooves.

[0050] After the motor 504 drives the three grippers 402 to clamp the mold core 2 at the center of the mounting base body 1, the motor 504 stops. Then, the three electric push rods 604 are controlled to operate synchronously. By extending the output axis of the three electric push rods 604 upwards, the hooks 602 deflect downwards with the first support seat 601 as the fulcrum. Using the lever principle, the three hooks 602 clamp the upper end of the mold core 2, thereby achieving a further reinforcement effect.

[0051] Further, please refer to Figures 2-6The mounting base body 1 is also provided with several third mounting mechanisms 7, and the several third mounting mechanisms 7 correspond to several clamping components 4 respectively. The third mounting mechanism 7 includes a card block 701 that is slidably disposed in the mounting base body 1. Several card slots 702 are equally spaced on the gripper 402, and the several card slots 702 are all adapted to the card block 701.

[0052] The third mounting mechanism 7 also includes a second support base 703 disposed within the mounting base body 1. A rotating rod 704 is rotatably disposed on the second support base 703. A third spur gear 705 is disposed on the rotating rod 704. Both the locking block 701 and the movable seat 101 are provided with racks 706, and both racks 706 mesh with the third spur gear 705.

[0053] The clamping jaw 402 has three equally spaced slots 702, and the clamping block 701 slides up and down along the inner wall of the mounting base body 1. A second support 703 is fixed to the bottom wall of the mounting base body 1, and a rotating rod 704 is rotatably mounted on the second support 703. A third spur gear 705 is fixed on the rotating rod 704. Racks 706 are fixed on both the clamping block 701 and the movable seat 101, and the two racks 706 mesh with the two sides of the third spur gear 705 respectively.

[0054] After the three electric push rods 604 operate, driving the three hooks 602 to engage with the upper end of the mold core 2, they continue to extend upwards, pressing the mold core 2 downwards through the three hooks 602. This causes the mold core 2 to slide downwards along the three clamps 402. At the same time, the movable seat 101 also moves downwards until it touches the bottom wall of the mounting base body 1, stopping the operation of the three electric push rods 604.

[0055] During this process, the movable seat 101 will drive the three inner racks 706 to move downward, and then through the transmission of the three third spur gears 705, drive the three outer racks 706 to move upward, and then drive the three locking blocks 701 to move upward, respectively locking into the three locking slots 702, thereby fixing the position of the three grippers 402 and playing a further reinforcing role.

[0056] It should be noted that by adding more card slots 702, more models and specifications of mold cores 2 can be adapted.

[0057] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0058] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
