Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, in particular to a quenching device for processing an automobile steering ball head. Background Art

[0002] The automobile steering ball head is an important component connecting the front axle and the steering knuckle of the automobile. It allows the wheel to move up and down while also performing steering operations. The design and performance of the steering ball head have a vital impact on the vehicle's handling, stability and safety. In the production of steering ball heads, a quenching device is required to ensure that the steering ball head obtains high strength, high hardness and good wear resistance through heat treatment, thereby ensuring the safety and reliability of the vehicle.

[0003] The existing quenching device for automobile steering ball head processing is transported by a conveyor belt, and then the induction heating mechanism uses the alternating magnetic field generated by the high-frequency current to form an eddy current effect on the surface of the workpiece, so that the surface layer is quickly heated to above the critical temperature, and then the heated automobile steering ball head is transported to the cooling position by the conveyor belt, and the nozzle on the spray pipe sprays cooling oil to the transported automobile steering ball head, so that the automobile steering ball head can be quenched quickly and continuously. However, in actual use, due to the fixed spraying angle of the nozzle, the amount of cooling oil that can be contacted by various positions of the automobile steering ball head is uneven, the heat exchange speed is slow, and the cooling speed of various positions of the automobile steering ball head is different, which affects the quenching speed and cooling uniformity. Summary of the invention

[0004] In view of this, the present invention aims at the deficiencies of the prior art and provides a quenching device for processing an automobile steering ball head. When quenching the automobile steering ball head, an appropriate amount of quenching cooling oil can be evenly sprayed on the surface of the automobile steering ball head, which can effectively improve the cooling efficiency of the automobile steering ball head and ensure the quenching effect.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a quenching device for processing automobile steering ball heads, comprising an outer shell, a partition is arranged inside the outer shell, a conveying seat is arranged between the outer shell and the partition, uniformly distributed rotating rollers are rotatably arranged inside the conveying seat, symmetrically distributed sprockets are fixedly sleeved on the outer sides of the rotating rollers, chains are transmitted between the sprockets located in the same vertical plane, a conveying mesh belt is arranged between the chains, uniformly distributed rotating seats are arranged on the inner wall of the outer shell, rotating rings are rotatably arranged between adjacent rotating seats, annular tubes are arranged on the inner arc surfaces of the rotating rings, and uniformly distributed nozzles are arranged on the side of the annular tubes close to the horizontal center of the outer shell; an induction quenching module is arranged inside the outer shell, and the induction quenching module is installed in coordination with the conveying mesh belt; uniformly distributed supporting feet are arranged on the lower surface of the outer shell, and rubber pads are arranged on the lower surface of the supporting feet.

[0006] As a further improvement of the present invention, a liquid tank is provided on the upper surface of the shell, and evenly distributed telescopic tubes are provided on the lower side of the liquid tank, and the telescopic tubes are respectively connected with adjacent annular tubes; a liquid storage tank is provided on the lower side of the inner part of the shell, and a delivery pipe is provided on the lower surface of the liquid storage tank, and an infusion pump is provided on the outer side of the liquid tank, and the infusion pump is connected with the delivery pipe.

[0007] As a further improvement of the present invention, symmetrically distributed rotating rods are rotatably arranged between the outer shell and the partition, and uniformly distributed gears are fixedly sleeved on the outer arc surface of the rotating rods, and external toothed rings are arranged in the mounting grooves opened on the outer arc surface of the rotating rings, and the gears are respectively meshed and connected with adjacent external toothed rings; a driving box is arranged on the outer side surface of the outer shell, and symmetrically distributed rotating shafts are rotatably arranged inside the driving box, and the rotating shafts are respectively fixed to adjacent rotating rods through couplings, and worm gears are fixedly sleeved on the outer sides of the rotating shafts, and uniformly distributed supports are arranged inside the driving box, and worms are rotatably arranged between the inner wall of the driving box and adjacent supports, and the worms are respectively meshed and connected with adjacent worm gears, and linkage shafts are rotatably arranged between two adjacent supports, and the linkage shafts are respectively fixed to adjacent worm gears through couplings, and a dual-axis motor is arranged inside the driving box, and the output shafts of the dual-axis motors are fixed to adjacent linkage shafts through couplings.

[0008] As a further improvement of the present invention, a control box is arranged on the outside of the shell, and the drive motor, the induction quenching module, the dual-axis motor and the infusion pump are all electrically connected to the control box.

[0009] In summary, compared with the prior art, the present application has at least one of the following beneficial technical effects:

[0010] Firstly, the induction quenching module uses the alternating magnetic field generated by high-frequency current to form an eddy current effect on the surface of the car steering ball head, causing the surface layer to quickly heat up to above the critical temperature, thereby achieving rapid heating of the car steering ball head; the heated car steering ball head is continued to be transported by the conveyor belt.

[0011] Secondly, the cooling oil in the liquid tank enters the interior of the annular tube through the telescopic tube, and the cooling oil is sprayed out by the nozzle on the annular tube. The meshing relationship between the gear and the outer gear ring drives the rotating ring where the outer gear ring is located to rotate, so that the rotating ring drives the nozzle to swing back and forth continuously while spraying the cooling oil.

[0012] Thirdly, by spraying cooling oil and continuously swinging the nozzle back and forth, the fully heated automobile steering ball head on the conveyor belt can be quickly and evenly sprayed with cooling oil, so that an appropriate amount of quenching cooling oil is evenly sprayed on the surface of the automobile steering ball head, which can effectively improve the cooling efficiency of the automobile steering ball head and ensure the quenching effect.

[0013] Fourthly, the quenching condition of the automobile steering ball head can be better observed through the observation window 1 and the observation window 2, so as to better control the quenching process of the automobile steering ball head.

[0014] Fifthly, the cooling oil flowing down from the surface of the steering ball head of the automobile falls into the interior of the liquid storage tank, and then the cooling oil in the interior of the liquid storage tank is re-injected into the liquid tank through the delivery pipe by the infusion pump, which can effectively avoid the waste of cooling oil.

[0024] like Figure 3 , 4 As shown, symmetrically distributed rotating rods 208 are rotatably arranged between the housing 101 and the partition 103, and uniformly distributed gears 209 are fixedly sleeved on the outer arc surface of the rotating rods 208. External toothed rings 207 are arranged in the mounting grooves opened on the outer arc surface of the rotating ring 202, and the gears 209 are respectively meshed and connected with adjacent external toothed rings 207; a driving box 210 is arranged on the outer side of the housing 101, and symmetrically distributed rotating shafts are rotatably arranged inside the driving box 210, and the rotating shafts are respectively fixed to the adjacent rotating rods 208 through couplings, and the outer sides of the rotating shafts are uniformly fixed to the outer arc surface of the rotating ring 202.
