Description

Technical Field

[0001] This utility model belongs to the field of brake disc casting technology and relates to a brake disc casting cooling device. Background Technology

[0002] Brake discs primarily function to slow down or stop a vehicle. They are typically made of cast iron, and the most common method for casting brake discs is sand casting. Sand casting refers to the casting method of producing castings in sand molds. After casting, the formed brake discs need to be cooled, thus requiring a cooling device.

[0003] A brake disc casting cooling device disclosed in Chinese patent CN219724561U includes a housing. A fan is bolted to one side of the outer wall of the housing, and a drive motor is bolted to one side of the top of the housing. A support rod is rotatably connected to the inner side of the housing, and several support discs are fixedly connected to the support rod. The top of the support rod penetrates through the top of the housing. A connecting rod is rotatably connected to one side of the top of the housing, and the top of the connecting rod is drively connected to the output shaft of the drive motor. The connecting rod and the support rod are meshed together.

[0004] The cooling device uses rotating support discs to allow airflow to cool the rotating brake discs. However, the arrangement of several support discs from top to bottom causes the top support discs to block the bottom support discs, resulting in insufficient cooling for the bottom brake discs.

[0005] To address the aforementioned problems, this utility model proposes a brake disc casting cooling device. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes a brake disc casting cooling device.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a box body, on which a blower is fixedly installed, and on the top of the box body, a number of ventilation slots are spaced apart.

[0008] The interior of the housing is connected to several rotating shafts at intervals from top to bottom. The rotating shafts are arranged horizontally, and each rotating shaft is fixedly connected to a load-bearing frame. Adjacent rotating shafts are connected by a chain drive assembly.

[0009] A drive assembly is provided at the bottom of the housing, which drives a bottommost rotating shaft to rotate.

[0010] Furthermore, one end of the rotating shaft is rotatably connected to the inner wall of the second side of the box, and the other end of the rotating shaft is rotatably connected to the inner wall of the third side of the box. The second and third sides of the box are adjacent to the first side of the box, and a cabinet door is installed on the fourth side of the box by means of a hinge.

[0011] Furthermore, several partitions are uniformly and fixedly connected inside the support frame. One end of each partition is fixedly connected to the middle of the support frame, and the other end of each partition is fixedly connected to the inner wall of the support frame.

[0012] Furthermore, the drive assembly includes a motor, which is fixedly connected to the inner wall of the third side of the housing. The output shaft of the motor rotates through the third side of the housing, and a turntable is coaxially fixedly connected to the end of the output shaft of the motor.

[0013] One end of the bottommost rotating shaft rotates through the third side of the box, and a gear is fixedly fitted on the end of the rotating shaft that extends outside the box. A transmission component is provided on the turntable. When the motor drives the turntable to rotate, the transmission component drives the gear to rotate.

[0014] Furthermore, the transmission component includes a rack, which is horizontally slidably disposed on the third side of the housing. The rack meshes with a gear, and a T-shaped connecting rod is fixedly connected to one end of the rack. The connecting rod is slidably disposed on one side of the turntable.

[0015] The end of the connecting rod away from the rack has a waist-shaped groove, which is vertically arranged. A connecting column is eccentrically fixed to one side of the turntable, and the connecting column is slidably connected inside the waist-shaped groove.

[0016] Furthermore, a guide block is fixedly connected to the third side of the housing, a protrusion is fixedly connected to the top of the guide block, the rack is slidably disposed on the top of the guide block, and a groove adapted to the protrusion is opened on the bottom surface of the rack, the groove being slidably disposed on the protrusion.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The brake disc casting cooling device fixes the support frame to the top of the rotating shaft, which is horizontally arranged. When cooling the brake disc on the support frame, the motor drives the turntable and connecting column to rotate. The connecting column moves inside the waist-shaped groove, which pushes the connecting rod and rack to move back and forth, causing the gear to rotate back and forth. By making the rotating shaft and support frame rotate back and forth, there is no obstruction between the support frames, allowing the blower to cool the brake discs on all the support frames from the side. At the same time, the support frame drives the brake disc to rotate, blowing air to different surfaces of the brake disc, thus improving the cooling efficiency.

[0019] 2. The brake disc casting cooling device is equipped with a support frame, which is fixedly connected to the rotating shaft. When the rotating shaft rotates, it will drive the support frame to rotate, so that the opening of the support frame faces the cabinet door, making it easier to take the brake disc off the support frame.

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-6 As shown, the technical solution adopted by this utility model is as follows: A brake disc casting cooling device includes a housing 1, and a blower 12 is fixedly installed on the first side of the housing 1. The blower 12 is driven by the eccentric rotation of the offset rotor inside the cylinder, which causes the volume change between the blades in the rotor slot to draw in, compress, and expel air. The blower 12 performs air cooling by blowing out the air. The blower 12 is an existing product.

[0029] The top of the enclosure 1 has several ventilation slots 6 spaced apart. The hot air inside the enclosure 1 is discharged through the ventilation slots 6.

[0030] Inside the housing 1, there are several rotating shafts 7 arranged horizontally, connected at intervals from top to bottom.

[0031] One end of the rotating shaft 7 is rotatably connected to the inner wall of the second side of the housing 1, and the other end of the rotating shaft 7 is rotatably connected to the inner wall of the third side of the housing 1. The second and third sides of the housing 1 are adjacent to the first side of the housing 1. This is to ensure that the air outlet of the blower 12 faces the rotating shaft 7, so that the air blows from the side to several rotating shafts 7.

[0032] A cabinet door 2 is hinged to the fourth side of the cabinet body 1. A handle is provided on the cabinet door 2.

[0033] A drive assembly is provided at the bottom of the housing 1, which drives a bottom-most rotating shaft 7 to rotate.

[0034] The drive assembly includes a motor 14, which is fixedly connected to the inner wall of the third side of the housing 1. The output shaft of the motor 14 rotates through the third side of the housing 1, and a turntable 11 is coaxially fixedly connected to the end of the output shaft of the motor 14. The turntable 11 is rotatably disposed on the outer side of the third side of the housing 1, and starting the motor 14 drives the turntable 11 to rotate.

[0035] One end of the bottommost rotating shaft 7 rotates through the third side of the housing 1, and a gear 3 is fixedly fitted onto the end of the rotating shaft 7 that extends outside the housing 1. The gear 3 is rotatably positioned on the outside of the third side of the housing 1.

[0036] A transmission component is provided on the turntable 11. When the motor 14 drives the turntable 11 to rotate, the transmission component drives the gear 3 to rotate.

[0037] The transmission component includes a rack 4, which is horizontally slidably mounted on the third side of the housing 1. One end of the rack 4 is fixedly connected to a T-shaped connecting rod 8, which is slidably mounted on one side of the turntable 11.

[0038] The end of the connecting rod 8 furthest from the rack 4 has a waist-shaped groove 9, which is vertically arranged. A connecting column 10 is eccentrically fixed to one side of the turntable 11, and the connecting column 10 is slidably connected inside the waist-shaped groove 9. When the turntable 11 drives the connecting column 10 to rotate, the connecting column 10 will move inside the waist-shaped groove 9, thereby pushing the connecting rod 8 and the rack 4 to move.

[0039] The rack 4 meshes with the gear 3. When the rack 4 moves, it drives the gear 3 to rotate, which in turn causes a shaft 7 at the bottom to rotate.

[0040] A guide block 5 is fixedly connected to the third side of the housing 1, and a protrusion is fixedly connected to the top of the guide block 5. A rack 4 is slidably mounted on the top of the guide block 5, and a groove that matches the protrusion is opened on the bottom surface of the rack 4. The groove is slidably mounted on the protrusion. The rack 4 is positioned on the top of the guide block 5 by the cooperation of the protrusion and the groove, so that the rack 4 can move horizontally at the bottom of the gear 3.

[0041] Two adjacent rotating shafts 7 are connected by a chain drive assembly 15. Chain drive is a transmission method that transmits the motion and power of a driving sprocket with a special tooth profile to a driven sprocket with a special tooth profile through a chain. The chain drive assembly 15 enables one rotating shaft 7 at the bottom to drive all rotating shafts 7 to rotate.

[0042] Each rotating shaft 7 is fixedly connected to a support frame 13. Several slots are evenly opened on the side of the support frame 13 to allow air to enter the interior of the support frame 13 through the slots.

[0043] Several partitions 16 are evenly fixedly connected inside the support frame 13. One end of each partition 16 is fixedly connected to the middle of the support frame 13, and the other end is fixedly connected to the inner wall of the support frame 13. The partitions 16 divide the inner cavity of the support frame 13 to facilitate the placement of brake discs separately. The height of the side of the support frame 13 is greater than the height of the brake disc, so that the brake disc is prevented from falling off when the support frame 13 rotates.

[0044] Working principle:

[0045] When in use, start the motor 14. The output shaft of the motor 14 drives the turntable 11 to rotate, causing the connecting column 10 to rotate around the rotation axis of the turntable 11.

[0046] The connecting column 10 moves inside the waist-shaped groove 9, which in turn pushes the waist-shaped groove 9 to move. Under the positioning action of the guide block 5 on the rack 4, the connecting rod 8 and the rack 4 move horizontally back and forth on the top of the guide block 5.

[0047] As the rack 4 moves, it drives the gear 3 to reciprocate, and the gear 3 drives a rotating shaft 7 at the bottom to rotate. Through the chain drive assembly 15, all the rotating shafts 7 rotate, causing all the load-bearing frames 13 to rotate.

[0048] Open cabinet door 2, and after aligning the opening of the support frame 13 with cabinet door 2, the support frame 13 will be tilted. Turn off motor 14, and the support frame 13 will stop rotating. Place the brake disc on the support frame 13, positioned between two adjacent partitions 16.

[0049] Close cabinet door 2, start motor 14 and blower 12. Select the appropriate airflow based on the weight of the brake disc.

[0050] The bearing frame 13 drives the brake disc to rotate back and forth. Since the brake disc has a certain weight and the rotation amplitude of the bearing frame 13 should not be too large, the brake disc will not wobble during the reciprocating rotation.

[0051] During the oscillation process, the blower 12 blows air onto different surfaces of the brake disc to cool it, and the brake discs do not block each other, resulting in good cooling effect.

[0052] After cooling is complete, open cabinet door 2 and remove the brake disc.

[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
