[0001] The invention relates to the field of automobile wheel hubs, and in particular to a weight-reduced automobile wheel hub. Background Art

[0002] Cars are common means of transportation in our lives, and car wheels are important parts of car components. Most of the current car wheels are composed of a hub flange and a reinforcing rib fixed on the hub flange, and then a corresponding fixing hole is opened on the hub flange. However, the thickness of the flange of the car wheel in the prior art is too large, which not only makes the weight of the car wheel too large, but also the thick flange is easy to form more gaps inside it during the casting process, thereby affecting the strength of the wheel hub. In addition, when drilling holes on the formed car wheel hub, the operator needs to find the position of the car wheel hub first, and then drill holes in sequence. After the drilling is completed, the debris on the processing table needs to be cleaned again, which seriously affects the processing efficiency. For this reason, this scheme proposes a weight-reduced car wheel hub. Summary of the invention

DETAILED DESCRIPTION

[0044] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0045] Example 1

[0046] Please combine Figure 1 A weight-reduced automobile wheel hub in this embodiment includes a hub flange 1, and the front of the hub flange 1 has a plurality of bosses 2, and the bosses 2 are provided with fixing holes. On the basis of the original automobile wheel hub, the wall thickness at the opening position of the flange of the original structure is retained and designed into evenly distributed bosses, and the thickness of the remaining parts is reduced and designed into a sloped shape, that is, the flange thickness in the area between adjacent bosses is reduced, which can not only reduce the overall weight of the hub, but also effectively avoid the quality problems caused by the large number of gaps inside the flange. The entire hub is cast in an integrated manner, and the fixing holes are processed later.

[0047] Example 2

[0048] Combination Figure 2-3 and Figure 5-8 , a processing device for a weight-reduced automobile wheel hub in this embodiment includes:

[0049] A bottom plate, the top of which is rotatably connected to a support column 10, a placement plate 3 for placing the hub flange 1 is installed on the top of the support column 10, and a servo motor for driving the support column 10 to rotate is installed on the bottom plate;

[0050] The drilling mechanism is used to drill holes on the boss 2. The drilling mechanism includes a mounting frame 5 installed on the bottom plate, a drilling machine 7 installed on the mounting frame 5, and a telescopic member 13 installed on the bottom plate for driving the mounting frame 5 to rise and fall. The mounting frame 5 is also equipped with a nozzle. The drilling mechanism also includes a water tank 6 installed on the bottom plate and a water pipe 8 connected between the water tank 6 and the nozzle. The water outlet of the nozzle points to the drill bit position of the drilling machine 7. The air outlet of the air compressor 12 is equipped with a booster pipe, and the booster pipe is connected to the water tank 6. The water supply pipe 8 is internally connected to increase the pressure in the water tank 6. The water supply pipe 8 includes a stainless steel pipe installed on the mounting frame 5 and a hose installed at the bottom of the stainless steel pipe. The setting of the hose will not be affected by the lifting of the mounting frame 5. The other end of the hose is connected to the bottom of the water tank 6, and the other end of the stainless steel pipe is connected to the nozzle. A valve is installed on the stainless steel pipe, and a fixed gear 11 is fixed to one end of the valve stem of the valve. A fixed rack 9 meshing with the fixed gear 11 is installed on the top of the water tank 6, and the fixed rack 9 is arranged along the extension direction of the telescopic member 13;

[0051] A material fixing mechanism, which is used to position and clamp the wheel hub placed on the placement disk 3. The material fixing mechanism includes a positioning block 14 fixed to the top surface of the placement disk 3, two clamping plates 15 installed on the top surface of the placement disk 3, and a transmission component used to drive the two clamping plates 15 to move closer to or away from each other. The top surface of the placement disk 3 is provided with two mounting grooves 26 arranged along its radial direction. The transmission component includes threaded columns 27 installed in the two mounting grooves 26, two moving blocks respectively threadedly sleeved on the two threaded columns 27, two transmission gears 19 respectively sleeved on the two threaded columns 27, and a driving member driving the two transmission gears 19 to rotate. The bottom of the transmission gear 19 extends to the bottom of the placement disk 3, and the tops of the two moving blocks are respectively connected to the two threaded columns 27. The bottom surface of a clamping plate 15 is fixedly connected, and the driving member includes a limiting ring 16 fixed to the top of the receiving plate 4, two movable racks 17 slidingly connected to the bottom surface of the placing plate 3, a fixed plate fixed between the two movable racks 17, and an abutment column 22 fixed on the outer wall of the fixed plate away from the movable rack 17. The ends of the two movable racks 17 away from the abutment column 22 are connected to the bottom surface of the placing plate 3 through a first spring, and the two movable racks 17 are respectively located at the bottom of the two transmission gears 19 and meshed with the two transmission gears 19. An arc-shaped groove 161 is provided on the inner wall of the limiting ring 16, and a ball is installed on the other end of the abutment column 22, and the ball abuts against the inner ring of the limiting ring 16. The setting of the ball can reduce the friction between the abutment column 22 and the limiting ring 16.

[0052] The working principle of this embodiment is as follows: after placing the wheel hub to be processed on the top of the placement table 3, the wheel hub flange 1 is pushed toward the side close to the positioning block 14, so that the positioning block 14 abuts between the two bosses 2 on the wheel hub flange 1, and then the servo motor is started to drive the support column 10 to rotate, so that the placement plate 3 rotates accordingly, and then the abutment column 22 slides along the inner ring of the limit ring 16. When the abutment column 22 gradually moves out of the groove 161, the two movable racks 17 are components that move toward the side away from the abutment column 22, and then It can drive the two transmission gears 19 to rotate forward, so that the two clamps 15 are close to each other, until the abutment column 22 completely comes out of the groove 161, and the two clamps 15 are clamped on the outer ring of the hub flange 1, so as to fix the hub flange 1. At this time, the first spring is in a compressed state. When the drilling is completed and the placement plate 3 is rotated back to the initial position, the abutment column 20 enters the groove 161 again. Under the action of the first spring, the two movable racks 17 also return to their original positions, so that the clamps 15 move away from each other and loosen the hub flange.

[0053] Example 3

[0054] Combination Figure 2-4The present embodiment is further improved on the basis of the embodiment 2 in that: the debris collection mechanism comprises a receiving tray 4 movably mounted on the outside of the support column 10 and two scrapers 18 connected to the outer wall of the support column 10 through an elastic member. The receiving tray 4 is located below the limiting ring 16 to catch the debris falling from the placing tray 3. A circular hole is provided at the center of the receiving tray 4 for the support column 10 to pass through, so as to ensure that the receiving tray 4 is movably mounted on the support column 10. The outer part of the column 10, and the inner wall of the bottom surface of the receiving tray 4 is a structure that bulges toward the center of the circle, so that the debris falling on the receiving tray 4 can slide to the edge of the receiving tray 4 more easily under the action of gravity, the bottom surface of the scraper 18 is an inclined surface that matches the inner wall of the bottom of the receiving tray 4, and a discharge port is opened on one side of the receiving tray 4. The elastic member cooperates with the transmission assembly and is used to press the scraper 18 down to abut against the top surface of the receiving tray 4 while the clamping plate 15 clamps the wheel hub 1, and when the clamping plate 15 releases the wheel hub 1 When the scraper 18 is driven to separate from the receiving plate 4, two limit grooves 25 arranged along its axial direction are provided on the outer wall of the support column 10. The elastic member includes a positioning column 24 installed in the limit groove 25 along the axial direction of the support column 10, a connecting plate 23 movably sleeved on the outside of the positioning column 24, and a fixed column 21 fixed on the top of the scraper 18. One end of the connecting plate 23 extends to the outside of the limit groove 25 and is fixed to the top of the fixed column 21. The two long sides of the connecting plate 23 respectively abut against the two long sides of the limit groove 25, thereby ensuring that the connecting plate 23 will not rotate outside the positioning column 24. The outside of the positioning column 24 is also movably sleeved on a second spring, and the second spring abuts between the bottom of the connecting plate 23 and the bottom of the limit groove 25. The bottom surfaces of the two movable racks 17 are fixed with abutment blocks 20. The end of the abutment block 20 away from the abutment column 22 is a right-angled triangle structure, and the inclined surface faces downward. The abutment block 20 is located above the connecting plate 23 and cooperates with it.

[0055] The implementation principle of the embodiment of the present application is as follows: when the movable rack 17 moves to the side away from the abutment column 22, it will drive the abutment block 20 to move at the same time, so that the abutment block 20 begins to abut against the connecting plate 23 and begins to press the connecting plate 23 down until the clamping plate 15 clamps the wheel hub flange 1, and the scraper 18 also abuts against the bottom inner wall of the receiving tray 4 under the pressure of the abutment block 23, and then begins to scrape up the debris on the receiving tray 4 with the rotation of the support column 10, and finally discharges it from the discharge port. When the clamping plate 15 loosens the wheel hub flange 1, the abutment block 20 also separates from the connecting plate 23 again with the movement of the movable rack 17, and the connecting plate 23 also bounces up again under the action of the second spring, and then separates from the receiving tray 4. In this way, the scraper 18 contacts the receiving tray 4 without fixing the wheel hub flange 1. At this time, the rotation of the placement plate 3 will not cause friction between the scraper 18 and the receiving tray 4.
