Description

Technical Field

[0001] This utility model relates to the field of automotive wheel hub technology, and in particular to a heat treatment material frame for wheel hubs. Background Technology

[0002] Wheel hubs are an important component of automobiles. Based on their material, wheel hubs can be divided into two main categories: steel wheel hubs and alloy wheel hubs. Alloy wheel hubs have advantages such as light weight, low inertial resistance, high manufacturing precision, and good heat dissipation, which help improve the vehicle's driving performance. After the aluminum alloy wheel hub is cast, the cast wheel hub blank needs to be sent to a heating furnace for heat treatment to modify the product's mechanical properties and internal structure. The heat treatment material frame is a carrier that carries the blank produced under low pressure into the heat treatment furnace. The entire heat treatment process includes loading, furnace entry, furnace exit, unloading, and then loading again, thus completing a single cycle.

[0003] However, in the existing technology, during the heat treatment process of wheel hubs, aluminum alloy wheel hubs are usually placed horizontally in the heat treatment frame. During the heating process, the heating of different plane positions is uneven, which affects the heating effect of the wheel hub. Therefore, further improvement is needed. To this end, we propose a wheel hub heat treatment frame. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a wheel hub heat treatment material frame.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a wheel hub heat treatment material frame, including a fixed base, a fixed plate fixedly installed on the upper end of the fixed base, a motor housing fixedly installed on the left front end of the left fixed plate, a stepper motor fixedly installed inside the motor housing, a coupling fixedly installed on the output end of the stepper motor, rotating rods symmetrically rotatably installed at both ends on the inward side of the fixed plate, the stepper motor being fixedly connected to the left front rotating rod via the coupling, a transmission wheel fixedly installed on the circumferential surface of the left rotating rod, and a transmission chain movably installed on the circumferential surface of the transmission wheel, adjacent... The transmission wheels are interconnected by a transmission chain. A fixed frame is fixedly installed between the rotating rods. A support plate is fixedly installed at the bottom center of the fixed frame. Bidirectional lead screws are evenly rotatably installed on the front and rear side walls of the fixed frame. A throttle is fixedly installed at the end of the bidirectional lead screw away from the fixed frame. A guide rod is evenly fixedly installed in the center of the fixed frame. Connecting blocks are symmetrically and movably installed on the circumferential surfaces of the bidirectional lead screw and the guide rod. The connecting block on the left is symmetrically threaded onto the circumferential surface of the bidirectional lead screw, and the connecting block on the right is symmetrically and movably sleeved onto the circumferential surface of the throttle. A clamping ring is fixedly installed between the connecting blocks.

[0006] Furthermore, connecting plates are symmetrically fixedly installed on the front and rear sides of the upper end of the fixed plate, and slots are symmetrically opened at the front and rear ends of the bottom of the fixed plate. The connecting plates are movably inserted into the slots, and adjacent fixed plates are movably connected through the connecting plates and slots. Fixed holes are evenly opened on the outward side of the connecting plates, and fixing bolts are threaded into the fixing holes. The connecting plates are fixedly installed in the slots through the fixing bolts. By movably inserting the connecting plates into the slots, adjacent fixed plates are connected. Then, by threading the fixing bolts into the fixing holes at different positions, the height between the connecting plates and the slots is adjusted, thereby adjusting the distance between adjacent fixed plates. This allows the wheel hub to move more easily to the upper end of the fixed frame, while avoiding collisions between the upper and lower wheel hubs during the rotation of the fixed frame with the wheel hub, which could damage the wheel hub and affect its use.

[0007] Furthermore, springs are symmetrically fixedly installed on the inner sidewall of the clamping ring, and a protective plate is fixedly installed on the end of the spring away from the clamping ring; the protective plate can move synchronously with the clamping ring during its movement, thereby reducing the damage caused by the clamping ring squeezing the wheel hub and improving the heating effect of the wheel hub.

[0008] Furthermore, the vertical cross-sectional dimensions of the connecting plate are consistent with those of the slot; this reduces the gap between the connecting plate and the slot, allowing the connecting plate to move more stably within the slot, thus ensuring the stability between adjacent fixed plates.

[0009] Furthermore, the height of the fixing plate is greater than the diameter of the fixed frame sweep; this prevents collisions between adjacent fixed frames during the rotation of the rotating rod, thus avoiding damage to the fixed frames and affecting their use.

[0010] Furthermore, the support plate is provided with uniformly spaced through holes, which allows heat to be transferred to the wheel hub through the through holes, thereby reducing the impact of the support plate on the wheel hub heating process and ensuring the heating effect of the wheel hub.

[0011] The beneficial effects of this utility model are:

[0012] 1. In use, the operator inserts the connecting plate into the slot and connects the fixing bolts to the fixing holes at different positions to adjust the distance between adjacent fixing plates. This allows the hub to move more easily to the top of the fixing frame, preventing collisions between the upper and lower hubs during the rotation of the hub and the fixing frame, thus avoiding damage to the hub and affecting its use. Then, a robotic arm places the aluminum alloy hub on top of the support plate. A throttle moves the connecting block via a two-way lead screw, and the connecting block, along with a clamping ring, clamps and fixes the hub. During the heat treatment of the hub, a stepper motor is started, causing the left front rotating rod and the transmission wheel to rotate. The left front transmission wheel, through a transmission chain, drives the left rear transmission wheel synchronously, causing the rotating rod to rotate the fixing frame. As the fixing frame rotates, the clamping ring rotates the hub, adjusting the hub's angle for more uniform and comprehensive heating, thus improving heating efficiency.

[0013] 2. In use, this utility model has a protective plate fixedly installed at the end of the spring away from the clamping ring. The protective plate moves synchronously with the clamping ring during its movement, which reduces the damage caused by the clamping ring squeezing the wheel hub. Furthermore, the support plate has through holes evenly spaced, which allow heat to be transferred to the wheel hub through the through holes, thereby reducing the impact of the support plate on the wheel hub during the heating process and ensuring the heating effect of the wheel hub.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, a wheel hub heat treatment material frame is disclosed, including a fixed base 1. A fixed plate 2 is fixedly installed on the upper end of the fixed base 1. A motor housing 7 is fixedly installed on the left front end of the left fixed plate 2. A stepper motor 8 is fixedly installed inside the motor housing 7. A coupling is fixedly installed on the output end of the stepper motor 8. Rotating rods 9 are symmetrically rotatably installed at both ends on the inward side of the fixed plate 2. The stepper motor 8 is fixedly connected to the left front rotating rod 9 through the coupling. A transmission wheel 10 is fixedly installed on the circumferential surface of the left rotating rod 9. A transmission chain 11 is movably installed on the circumferential surface of the transmission wheel 10. Adjacent transmission wheels 10 are connected to each other through the transmission chain 11. A fixed frame 12 is fixedly installed between the rotating rods 9. A support plate 13 is fixedly installed at the bottom center of the fixed frame 12. Bidirectional lead screws 14 are evenly rotatably installed on the front and rear side walls of the fixed frame 12. A handle 15 is fixedly installed at the end of the bidirectional lead screw 14 away from the fixed frame 12. Guide rods 16 are evenly fixedly installed in the middle of the fixed frame 12. Connecting blocks 17 are symmetrically and movably installed on the circumferential surfaces of the bidirectional lead screw 14 and the guide rod 16. The left connecting block 17 is symmetrically threaded onto the circumferential surface of the bidirectional lead screw 14, and the right connecting block 17 is symmetrically and movably sleeved on the circumferential surface of the handle 15. A clamping ring 18 is fixedly installed between the connecting blocks 17.

[0023] In this embodiment, the operator uses a robotic arm to move the aluminum alloy hub above the fixed frame 12, then places the hub above the support plate 13. The throttle 15 rotates the bidirectional lead screw 14, which in turn moves the clamping ring 18 via the connecting block 17, thus clamping and fixing the hub. During the heat treatment of the hub, the stepper motor 8 is started, causing the left front-end rotating rod 9 and the transmission wheel 10 to rotate. The left front-end transmission wheel 10 rotates synchronously via the transmission chain 11, causing the rotating rod 9 to rotate the fixed frame 12. As the fixed frame 12 rotates, the clamping ring 18 rotates the hub, adjusting the hub's angle for more uniform and comprehensive heating, thus improving heating efficiency.

[0024] Specifically, connecting plates 3 are symmetrically fixedly installed on the front and rear sides of the upper end of the fixed plate 2, and slots 4 are symmetrically opened at the front and rear ends of the bottom of the fixed plate 2. The connecting plates 3 are movably inserted into the slots 4. Adjacent fixed plates 2 are movably connected through the connecting plates 3 and slots 4. Fixed holes 5 are evenly opened on the outward side of the connecting plate 3. Fixed bolts 6 are threaded into the fixed holes 5. The connecting plates 3 are fixedly installed in the slots 4 through the fixed bolts 6.

[0025] By inserting the connecting plate 3 into the slot 4, the adjacent fixing plates 2 are connected. Then, by threading the fixing bolt 6 into the fixing holes 5 at different positions, the height between the connecting plate 3 and the slot 4 is adjusted, thereby adjusting the distance between the adjacent fixing plates 2, so that the wheel hub can be moved more easily to the upper end of the fixing frame 12.

[0026] Specifically, springs 19 are symmetrically fixedly installed on the inner sidewall of the clamping ring 18, and a protective plate 20 is fixedly installed on the end of the spring 19 away from the clamping ring 18.

[0027] By fixing a protective plate 20 to one end of the spring 19 away from the clamping ring 18, the protective plate 20 can move synchronously with the clamping ring 18 as it moves, thereby reducing the damage caused by the clamping ring 18 squeezing the wheel hub.

[0028] Specifically, the vertical cross-sectional dimensions of the connecting plate 3 are the same as those of the slot 4;

[0029] By making the vertical cross-sectional dimensions of the connecting plate 3 consistent with those of the slot 4, the gap between the connecting plate 3 and the slot 4 can be reduced, thereby allowing the connecting plate 3 to move more stably in the slot 4.

[0030] Specifically, the height of the fixed plate 2 is greater than the diameter of the fixed frame 12.

[0031] By making the height of the fixed plate 2 greater than the diameter of the fixed frame 12, collisions between adjacent fixed frames 12 can be avoided during the rotation of the fixed frame 12 by the rotating rod 9.

[0032] Specifically, through holes are evenly distributed on the support plate 13;

[0033] By uniformly opening through holes on the support plate 13, heat can be transferred to the wheel hub through the through holes, thereby reducing the impact of the support plate 13 on the wheel hub heating process.

[0034] Working principle: The operator connects adjacent fixing plates 2 by inserting the connecting plate 3 into the slot 4. Then, by threading the fixing bolts 6 into the fixing holes 5 at different positions, the height between the connecting plate 3 and the slot 4 is adjusted, thereby adjusting the distance between adjacent fixing plates 2. A robotic arm then moves the aluminum alloy hub above the fixing frame 12 and places it above the support plate 13. The throttle 15 rotates the bidirectional lead screw 14, and during this rotation, the bidirectional lead screw 14 moves the clamping ring 18 via the connecting block 17. The movement of the clamping ring 18 clamps and fixes the hub. During the heat treatment of the hub, the stepper motor 8 is started, causing the stepper motor 8 to rotate the left front rotating rod 9 and the transmission wheel 10. Then, the left front transmission wheel 10 rotates synchronously with the left rear transmission wheel 10 through the transmission chain 11. This causes the rotating rod 9 to rotate the fixing frame 12. As the fixing frame 12 rotates, the clamping ring 18 rotates the hub, thereby adjusting the angle of the hub to allow for more uniform and comprehensive heating and improve heating efficiency.
