Description

Technical Field

[0001] This utility model belongs to the field of automotive heat treatment technology, and in particular relates to a heat treatment device for automotive steering tie rods. Background Technology

[0002] Steering tie rods are important components in automotive steering mechanisms, directly affecting vehicle handling stability, operational safety, and tire lifespan. The straight tie rod is responsible for transmitting the movement of the steering rocker arm to the steering knuckle arm; the lateral tie rod is the base of the steering trapezoidal mechanism and a key component ensuring the correct movement relationship between the left and right steering wheels.

[0003] Existing steering tie rods are typically cooled by being directly immersed in a cooling tank. However, hot water (which is at a higher temperature) has a lower density and tends to stay above cold water (which is at a lower temperature). This results in a large temperature difference between the water inside the tank, causing uneven cooling rates between the upper and lower parts of the steering tie rod. This can easily lead to deformation or cracking of the steering tie rod. To address this, we provide a heat treatment device for automotive steering tie rods. Utility Model Content

[0004] The purpose of this invention is to provide a heat treatment device for automotive steering tie rods. By rotating the stirring blades, the water inside the cooling tank is agitated, creating eddies. However, the water above the filter plate is blocked by the turbulence block and the filter plate, preventing the formation of eddies. This results in a uniform temperature distribution of the water inside the cooling tank, allowing the steering tie rod to cool evenly during the quenching process. This solves the problem of excessive temperature differences in the water inside the existing water tank, which causes uneven cooling rates between the upper and lower parts of the steering tie rod, easily leading to deformation or cracking of the steering tie rod.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0014] A circulation component, installed on the left side of the agitator, is used to replace the water flow inside the agitator; and

[0015] A disturbance component, which is installed inside an agitation component, is used to disturb the water flow;

The threaded rod extends into the interior of the fixed rod on the left side. A moving block is threadedly connected to the outer surface of the fixed rod. An electric telescopic rod is fixedly connected to the top of the moving block.

[0019] The motor starts to move the moving block, which in turn moves the steering tie rod.

[0020] Furthermore, the clamping assembly includes a fixed plate disposed at the bottom of the movable block. The top of the fixed plate is fixedly connected to the bottom output end of the electric telescopic rod. A second motor is fixedly connected to the right side of the fixed plate. A second threaded rod is fixedly connected to the left output end of the second motor via a coupling. The left side of the second threaded rod extends into the interior of the fixed plate. A clamping plate is threadedly connected to the outer surface of the second threaded rod. A limit rod is fixedly connected to the inner wall of the fixed plate. The outer surface of the limit rod is slidably connected to the inner wall of the clamping plate.

[0021] The motor is started to drive the threaded rod to rotate, and the rotation of the threaded rod drives the two clamping plates to move closer together to clamp the steering tie rod. The side of the clamping plates that are close to each other is provided with protective teeth.

[0022] Furthermore, the agitation assembly includes a cooling tank fixedly connected to the top of the base plate, a motor three fixedly connected inside the base plate, a rotating shaft fixedly connected to the top output end of the motor three via a coupling, the top of the rotating shaft extending into the interior of the cooling tank, and a stirring blade fixedly connected to the outer surface of the rotating shaft;

[0023] The motor starts the rotating shaft, which in turn drives the stirring blades to agitate.

[0027] This utility model has the following beneficial effects:

[0028] 1. This utility model uses a turbulence block to specifically drive the rotating shaft to rotate, which in turn drives the stirring blade to rotate. The rotating blade stirs the water inside the cooling tank, creating a vortex. However, the water above the filter plate is blocked by the turbulence block and the filter plate, preventing the vortex from forming. This results in a uniform temperature distribution of the water inside the cooling tank, allowing the steering tie rod to be cooled evenly during the quenching process.

[0029] 2. This utility model uses a fixed plate. Specifically, when the motor starts, it drives the threaded rod to rotate, which in turn drives the moving block to rotate. As the moving block rotates, it simultaneously drives the electric telescopic rod to move. The electric telescopic rod then moves the fixed plate above the heating tank, where the steering rod is placed to begin heating. After heating, the fixed plate re-clamps the steering rod, and the motor is started again to send the steering rod above the cooling tank and place it inside. This eliminates the need for workers to handle the steering rod, improving work safety.

[0054] The clamping assembly 13 includes a fixed plate 131 disposed at the bottom of the movable block 123. The top of the fixed plate 131 is fixedly connected to the bottom output end of the electric telescopic rod 124. A second motor 132 is fixedly connected to the right side of the fixed plate 131. A second threaded rod 133 is fixedly connected to the left output end of the second motor 132 via a coupling.

A limit rod 134 is fixedly connected to the inner wall of the fixed plate 131. The outer surface of the limit rod 134 is slidably connected to the inner wall of the clamping plate 135.

[0055] The system involves starting motor 132 to rotate threaded rod 133, which in turn moves two clamping plates 135 closer together to hold the steering tie rod. Protective teeth are provided on the side of the clamping plates 135 where they are close together. Starting motor 121 to rotate threaded rod 122, which in turn rotates moving block 123. Simultaneously, the moving block 123 moves electric telescopic rod 124, which moves fixing plate 131 above heating tank 113. The steering tie rod is then placed into heating tank 113 for heating. After heating, fixing plate 131 re-clamps the steering tie rod, and motor 121 is started to move the steering tie rod above cooling tank 211 and place it inside. This eliminates the need for workers to handle the steering tie rod, improving safety.

[0056] The stirring assembly 21 includes a cooling tank 211 fixedly connected to the top of the base plate 111. A motor 212 is fixedly connected inside the base plate 111. A rotating shaft 213 is fixedly connected to the top output end of the motor 212 via a coupling. The top of the rotating shaft 213 extends into the cooling tank 211. A stirring blade 214 is fixedly connected to the outer surface of the rotating shaft 213.

[0057] Among them, the motor 212 starts and drives the rotating shaft 213 to rotate, and then the rotating shaft 213 drives the stirring blade 214 to stir.

[0058] The circulation component 22 includes a water tank 221 fixedly connected to the top of the base plate 111. A connecting plate 224 is fixedly connected inside the water tank 221. A cooler 225 is fixedly connected to the inner wall of the connecting plate 224. A water pump 222 is fixedly connected to the top of the water tank 221. There are two water pumps 222. A delivery pipe 223 is fixedly connected to the right side of each water pump 222. The right side of the delivery pipe 223 is fixedly connected to the left side of the cooling tank 211.

[0059] The disturbance component 23 includes a turbulence block 231 fixedly connected to the inner wall of the cooling tank 211, and a filter plate 232 fixedly connected to the inner wall of the cooling tank 211.

[0060] There are two water pumps 222. The top water pump 222 is located on top of the water injection tank 221, and the bottom water pump 222 is located inside the water injection tank 221. The motor 212 starts and drives the rotating shaft 213 to rotate. Then, the rotating shaft 213 drives the stirring blade 214 to rotate. The rotating blade 214 stirs the water inside the cooling tank 211, causing the water to generate eddies. However, the water above the filter plate 232 is blocked by the turbulence block 231 and the filter plate 232, so that the eddies cannot be formed. This makes the temperature distribution of the water inside the cooling tank 211 uniform, so that the steering tie rod can be cooled evenly during the quenching process.

[0061] A specific application of this embodiment is as follows: In use, first place the steering tie rod below the fixed plate 131 and make the steering tie rod vertical. Then, start the electric telescopic rod 124. The electric telescopic rod 124 pushes the fixed plate 131 downward so that the steering tie rod is aligned with the center of the clamping plate 135. Then, start the second motor 132. The second motor 132 drives the second threaded rod 133 to rotate. Since the second threaded rod 133 is double-threaded with opposite threads, the rotation of the second threaded rod 133 will cause the clamping plates 135 to move closer together. Then, the movement of the clamping plates 135 together will adjust the steering tie rod. The top of the rod is clamped. After clamping, the electric telescopic rod 124 retracts, pulling the steering rod upward. Then, motor 121 is started, driving the threaded rod 122 to rotate. The rotation of the threaded rod 122 then drives the moving block 123 to rotate. As the moving block 123 rotates, it synchronously drives the electric telescopic rod 124 to move. The movement of the electric telescopic rod 124 moves the fixing plate 131 above the heating tank 113. Then, the steering rod is placed into the heating tank 113 to begin heating. After heating is completed, the fixing plate 131 is repositioned... The steering tie rod is clamped, and motor 121 is started to send the steering tie rod above the cooling tank 211 and into the tank, allowing it to fall above the filter plate 232 to begin cooling. Simultaneously, motor 212 is started, driving the rotating shaft 213 to rotate. The rotation of the shaft 213 then drives the stirring blade 214 to rotate, agitating the water inside the cooling tank 211 and creating a vortex. However, the water above the filter plate 232 is blocked by the turbulence block 231 and the filter plate 232, preventing the formation of a vortex and thus hindering cooling. The water temperature inside the cooling tank 211 is evenly distributed, allowing the steering tie rod to cool evenly during the quenching process. When the water temperature inside the cooling tank 211 is too high, the cooler 225 is started first to cool the water inside the water tank 221. After cooling is completed, two water pumps 222 are started simultaneously. The water pump 222 above the water tank 221 works with the delivery pipe 223 to draw water from inside the cooling tank 211 into the water tank 221. The water pump 222 at the bottom and the delivery pipe 223 send the cooled water from the water tank 221 into the cooling tank 211, completing the water replacement inside the cooling tank 211.
