Description

Technical Field

[0001] The invention relates to the technical field of disc brake pad processing devices, and in particular to a disc brake pad heat treatment storage device. Background Art

[0002] Disc brakes are a common braking system, which generally consist of a brake disc fixed on the wheel hub and a brake caliper clamped on both sides of the brake disc. When working, the brake caliper pushes the brake pads against the brake disc to slow down or stop the vehicle.

[0003] The production of disc brake pads includes BP treatment, pre-pressing, thermoforming, heat treatment and post-processing. Heat treatment is a key step in the preparation process and has a significant impact on the quality of the brake pads. Heat treatment is generally carried out using equipment such as curing furnaces or ovens. In batch processing, storage devices are generally required to place the brake pads.

Through the design of the storage frames 5, batches of brake pad bodies 2 can be stored before heat treatment, and batches of brake pad bodies 2 can also be stored after heat treatment, which is convenient for staff to carry and process batches of brake pad bodies 2, effectively improving work efficiency. A plurality of legs 3 are fixedly installed at the bottom of the placement rack 1, and the legs 3 are designed to ensure the placement stability of the placement rack 1.

[0036] The placement rack 1 is provided with a plurality of installation cavities 4, each of which is fixedly provided with a storage frame 5. The placement rack 1 is provided with a lifting assembly matched with the plurality of storage frames 5, and the lifting assembly is used to move the brake pad body 2 downward for storage or upward for ejection in the storage frame 5. The lifting assembly is composed of a screw rod 6, a mounting rod 7, a plurality of fixing blocks 8 and a plurality of lifting plates 10. The screw rod 6 is rotatably installed at the bottom of the placement rack 1, and the mounting rod 7 is threadedly installed on the screw rod 6. The plurality of lifting plates 10 are fixedly installed on the mounting rod 7 through the corresponding fixing blocks 8, and each lifting plate 10 is respectively located in the corresponding storage frame 5, and the side of each storage frame 5 is provided with a plurality of lifting plates 10. The walls are provided with through grooves 9 which cooperate with the corresponding fixing blocks 8. When the screw rod 6 rotates, multiple lifting plates 10 can be driven to move up and down at the same time through the mounting rod 7. When the brake pad body 2 needs to be placed, a batch of brake pad bodies 2 are first placed in the storage frame 5, and then the screw rod 6 is rotated, and the upward movement of the lifting plate 10 drives the brake pad body 2 to move upward, and then the top brake pad body 2 can be placed. When retrieving the brake pad body 2, the brake pad body 2 is placed in the storage frame 5 in turn, and the screw rod 6 is rotated in the opposite direction to allow the lifting plate 10 to move downward in an orderly manner, so that the brake pad body 2 can be retrieved and stored.

[0037] A movable plate 11, a plurality of suction cups 12 are fixedly connected to the bottom of the movable plate 11, a pressure chamber is arranged in the movable plate 11, the top of the suction cup 12 is communicated with the pressure chamber, the suction cup 12 is made of high temperature resistant material, and the plurality of suction cups 12 are used for sucking or unloading a plurality of brake pad bodies 2, specifically, each two suction cups 12 form a group, which are used for stably sucking a brake pad body 2, when the brake pad body 2 is sucked by the suction cup 12, the movement of the movable plate 11 can drive the brake pad body 2 to move along the placement rack 1, and after moving to the designated position, the suction cup 12 releases the brake pad body 2, and the brake pad body 2 can be placed at the designated position on the placement rack 1.

[0038] A traveling assembly that cooperates with the moving plate 11 is installed on the placement rack 1. The traveling assembly is used to move the moving plate 11 left and right along the placement rack 1. The traveling assembly consists of a screw 20, two moving grooves 19, two moving blocks 18 and two support blocks 17. The two moving grooves 19 are both opened on the placement rack 1. The two moving blocks 18 are respectively slidably installed in the corresponding moving grooves 19. The two support blocks 17 are respectively fixedly installed between the moving plate 11 and the two moving blocks 18. The screw 20 is rotatably installed in one of the moving grooves 19, and the screw 20 is threadedly connected to the corresponding moving block 18. When the screw 20 rotates, it can drive the moving block 18 to move in the moving groove 19, thereby driving the moving plate 11 to move along the placement rack 1 to control the placement position of the brake pad body 2.

[0039] The driving rod 21 is rotatably mounted on the placement frame 1, and a handle 38 is fixedly mounted on the driving rod 21. A transmission assembly is installed between the driving rod 21 and the lifting assembly. The transmission assembly consists of a rotating rod 23, a belt transmission structure 22, an active bevel gear 24 and a driven bevel gear 25. The rotating rod 23 is rotatably mounted on the placement frame 1, the belt transmission structure 22 is installed between the rotating rod 23 and the driving rod 21, the active bevel gear 24 is fixedly mounted on the rotating rod 23, and the driven bevel gear 25 is fixedly mounted on the rotating rod 23. On the screw rod 6, the driven bevel gear 25 is meshed with the active bevel gear 24, and the belt transmission structure 22 allows the driving rod 21 to transmit the rotating rod 23 in a one-to-one ratio, and then through the cooperation of the active bevel gear 24 and the driven bevel gear 25, the screw rod 6 can be driven to rotate at the same time. By designing the thread lead of the screw rod 6, the upward moving height of the lifting plate 10 is equal to the thickness of a brake pad body 2 every time the driving rod 21 rotates one circle, and then each brake pad body 2 can be transported or recovered for storage in sequence.

[0040] The belt transmission structure 1 22 is composed of a pulley 1, a pulley 2 and a belt. The pulley 1 is fixedly mounted on the rotating rod 23, the pulley 2 is fixedly mounted on the driving rod 21, the belt is mounted between the pulley 1 and the pulley 2, and the belt is an elastic belt. The heat insulating sleeve 13 and the placement frame 1 are jointly provided with a Z-shaped shift groove, the shift groove is matched with both ends of the driving rod 21, and the shift groove is divided into two gears, one is a contact gear, and the other is a separation gear. Figure 8 The driving rod 21 is shown in the contact position, at which time the driving gear 36 cooperates with the convex tooth 35. When the driving rod 21 is in the disengagement position, the driving gear 36 is separated from the convex tooth 35. At this time, the rotation of the driving rod 21 will not drive the connecting rod 26 to rotate.

[0041] A synchronous self-adjusting drive assembly is installed between the driving rod 21 and the traveling assembly. The synchronous self-adjusting drive assembly is used to automatically adjust the moving speed and direction of the traveling assembly according to the rotation direction and rotation angle of the driving rod 21. A grid area and an installation area are provided on the placement rack 1. The brake pad body 2 is located on the grid area during heat treatment. The storage frame, lifting assembly, traveling assembly, transmission assembly and synchronous self-adjusting drive assembly are all located on the installation area.

[0042] The synchronous self-adjusting drive assembly consists of a connecting rod 26, a belt transmission structure 27, a driving gear 36, a transmission gear 37 and a speed regulating mechanism. The connecting rod 26 is rotatably mounted on the placement rack 1, and the belt transmission structure 27 is installed between the connecting rod 26 and the screw 20. The belt transmission structure 27 is also a prior art, and its working principle and specific structure are not elaborated here. The design of the belt transmission structure 27 makes the transmission ratio of the connecting rod 26 to the screw 20 one to one, the driving gear 36 is fixedly mounted on the driving rod 21, and the transmission gear 37 is fixedly mounted on the connecting rod 26.

[0043] The speed regulating mechanism is composed of a support rod 28, a transmission rod 29, a fixed gear 30, a fixed rack 31, a push rod 32, a round rod 34 and a plurality of convex teeth 35. The support rod 28 is fixedly mounted on the bottom of the placement rack 1, the transmission rod 29 is rotatably mounted on the support rod 28, the fixed gear 30 is fixedly mounted on one end of the transmission rod 29, the fixed rack 31 is fixedly mounted on the bottom of the mounting rod 7, and the fixed rack 31 is meshed with the fixed gear 30. Under the meshing effect of the fixed rack 31 and the fixed gear 30, when the mounting rod 7 moves, the transmission rod 29 can be driven to rotate;

[0044] The push rod 32 is threadedly connected to the end of the transmission rod 29 away from the fixed gear 30. A guide rod 33 that slides with the push rod 32 is fixedly installed on the side wall of the placement rack 1. The round rod 34 is rotatably installed at the end of the push rod 32 away from the fixed gear 30. A plurality of convex teeth 35 are fixedly installed on the side wall of the round rod 34, and the plurality of convex teeth 35 are divided into a plurality of gear rings with different numbers of teeth on the round rod 34 from left to right. The plurality of gear rings cooperate with the driving gear 36 and the transmission gear 37. When the transmission rod 29 rotates, the push rod 32 drives the round rod 34 to move back and forth between the driving rod 21 and the connecting rod 26. At this time, the meshing relationship between the different gear rings thereon and the driving gear 36 and the transmission gear 37 is switched. When the lifting plate 10 is located at the top in the storage frame 5, the gear ring with the least number of teeth meshes with the driving gear 36 and the transmission gear 37. At this time, the rotation of the driving rod 21 drives the number of turns of the connecting rod 26 to be small, so the rotation speed of the screw 20 is slow, and the moving plate 11 has the shortest moving distance on the placement rack 1, and when the lifting plate 10 moves down a certain thickness of the brake pad body 2 in the storage frame 5, the number of teeth of the gear ring meshing with the driving gear 36 and the transmission gear 37 will gradually increase, and the moving distance of the movable plate 11 will increase. Then, the moving distance of the movable plate 11 can be synchronously controlled by the number of brake pad bodies 2 in the storage frame 5, so that the brake pad bodies 2 can be placed at different positions on the placement rack 1, and the brake pad bodies 2 at different positions can be retracted into the storage frame 5 after the heat treatment is completed. The number of teeth of different gear rings can be adjusted according to the placement position spacing of the brake pad bodies 2, so that the transmission ratio of the driving rod 21 to the connecting rod 26 can be changed in real time, which can meet the orderly placement and retrieval processing. The length of the convex tooth 35 is greater than the thickness of the driving gear 36 and the transmission gear 37, and the spacing between different gear rings is also greater than the thickness of the driving gear 36 and the transmission gear 37.

[0045] The tooth spacing of the driving gear 36 is equal to the tooth spacing of the transmission gear 37, and the diameter and the number of teeth of the driving gear 36 are greater than the diameter and the number of teeth of the transmission gear 37. Since the travel distance of the movable plate 11 is greater than the upward movement distance of the mounting rod 7, the rotation of the driving rod 21 can be better utilized by changing the transmission ratio while stably controlling the movement of both.

[0046] A heat-insulating sleeve 13 cooperating with a synchronous self-adjusting drive assembly is fixedly mounted on the side wall of the placement rack 1, a handle 38 is fixedly mounted on one end of the drive rod 21 outside the heat-insulating sleeve 13, and a sealing heat-insulating plate 39 is fixedly mounted on the heat-insulating sleeve 13. The sealing heat-insulating plate 39 can be used to seal the door body of the heat treatment device.

[0047] A negative pressure machine 14 is fixedly installed on the heat-insulating sleeve 13, and two connecting pipes 15 are connected between the negative pressure machine 14 and the movable plate 11. A control switch 16 is fixedly installed on the side wall of the negative pressure machine 14. The negative pressure machine 14 is an existing product, which generates negative pressure when working. The control switch 16 is used to control the switch of the negative pressure machine 14. When the brake pad body 2 is heat-treated, the staff first places the brake pad body 2 to be treated in the corresponding storage frame 5, and then turns the handle 38 clockwise, one circle each time, and cooperates with the switch of the control switch 16 during the process of turning the handle 38 to move the movable plate 11. Control it to move the top brake pad body 2 to the end of the placement rack 1 farthest from the storage frame 5, then rotate it counterclockwise for one circle to reset the movable plate 11, then switch the drive rod 21 to the separation gear, and rotate it clockwise for one circle, then switch the drive rod 21 to the contact gear, and then continue to rotate it clockwise for one circle. At this time, the transmission ratio of the drive gear 36 and the transmission gear 37 has changed, and the moving distance of the movable plate 11 has also changed accordingly. Repeating this operation can complete the placement and retrieval of the brake pad bodies 2 at different positions, which can greatly reduce the work intensity and improve the placement accuracy.

[0048] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
