Description

Technical Field

[0001] The present invention relates to the technical field of brake disc housing processing, and particularly to a slag removal device for processing automotive brake disc housings. Background Art

[0002] As a core component of the automotive braking system, the machining accuracy of the automotive brake disc housing directly affects driving safety. During the machining processes of the brake disc housing, such as cutting, milling, and drilling, a large amount of metal chips, cutting fluid mixtures, and powdery waste residues will be generated. The accumulation of waste residues may entangle the cutting tools, resulting in increased tool wear. At the same time, the waste residue particles are embedded in the surface of the workpiece, causing scratches on key parts such as the mounting surface and friction surface of the brake disc housing.

[0003] In the existing automotive brake disc housing processing scenarios, the slag removal operation highly relies on manual operation. Especially when dealing with complex structural parts such as the ventilation holes, bolt counterbores, and curved surface grooves of the brake disc housing, the traditional brush is difficult to penetrate deeply due to size limitations, resulting in incomplete cleaning of the waste residues. For example, the metal chips in the ventilation holes need to be cleaned with the assistance of tweezers or air guns, and the compressed air blowing is likely to cause the waste residues to splash onto the machined surface, causing secondary pollution. At the same time, the metal dust generated during the cleaning process suspends in the air, affecting the working environment. Therefore, it is necessary to design a slag removal device for processing automotive brake disc housings.

[0004] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application. Therefore, it may include information that does not constitute the prior art. Summary of the Invention

[0024] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in conjunction with the attached drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present invention as follows.

[0025] The following, in conjunction with the attached drawings, details the technical solutions provided by various embodiments of the present invention.

[0026] Referring to Figures 1 to 4 as shown, the embodiment of the present invention provides a slag removal device for processing an automobile brake disc housing, mainly including a processing assembly 1, a rotating assembly 2 and a slag removal assembly 3;

[0027] Referring to Figure 1 as shown, the processing assembly 1 includes a workbench 11, the workbench 11 has a placing surface 13, and a protective cover 12 is fixedly installed on the workbench 11, and the protective cover 12 is used to enclose the workbench 11;

[0028] Referring to Figures 2 - 4 as shown, the rotating assembly 2 includes an indexing plate 21 penetrating through the placing surface 13, and at the same time, a motor (not marked in the figure) is fixedly installed on the side of the workbench 11 away from the protective cover 12, and the output shaft of the motor is coaxially connected to the indexing plate 21. When the motor receives a pulse signal, its rotor drives the output shaft to rotate a specific angle (such as 45°), and the torque is transmitted to the indexing plate 21 through key connection;

[0029] Moreover, a plurality of fixing parts 22 are inserted into the indexing plate 21. The plurality of fixing parts 22 are equally spaced along the circumferential direction of the indexing plate 21. The fixing part 22 is a hollow structure, and the fixing part 22 has an extending part 23. The extending part 23 extends into the workbench 11. At the same time, a through hole (not shown in the figure) adapted to the extending part 23 is formed in the workbench 11. A step 24 is fixedly sleeved on the fixing part 22. The step 24 fits against the upper surface of the workbench 11. A brake disc housing 25 is placed on the step 24. The brake disc housing 25 is placed on the step 24 and sleeved on the top end of the fixing part 22;

[0030] It should be noted that an anti-slip layer is provided at the contact position between the through hole on the workbench 11 and the extending part 23. The anti-slip layer is made of silica gel material, so that the extending part 23 of the fixing part 22 can be tightly inserted into the through hole through the anti-slip layer, and at the same time, it is convenient for disassembly, so as to place brake disc housings 25 of different sizes;

[0031] At the same time, the brake disc housing 25 has a concave hole. An anti-slip ring is provided at the contact position between the fixing part 22 and the concave hole. The anti-slip ring is made of silica gel material, so that the brake disc housing 25 can be tightly sleeved on the top end of the fixing part 22 through the anti-slip ring;

[0032] After receiving the pulse signal, the motor drives the output shaft to drive the coaxially connected indexing plate 21 to rotate, and transmits the torque through key connection to achieve precise rotation of 45° each time. The fixing part 22 on the indexing plate 21 sleeved the brake disc housing 25 through the hollow structure, and the anti-slip ring (silica gel material) at its top end fits tightly with the concave hole of the housing to provide circumferential friction;

[0033] The extending part 23 of the fixing part 22 is inserted into the through hole of the workbench 11. The silica gel anti-slip layer at the contact position not only ensures the plugging stability but also facilitates quick disassembly and replacement. When the motor drives the indexing plate 21 to rotate, the fixing part 22 synchronously drives the brake disc housing 25 to rotate, and the positioning pin cooperates with the positioning groove of the workbench 11 to achieve angle locking, ensuring the rotation accuracy and meeting the high-efficiency positioning requirements of multi-station processing.

[0034] In order to remove the waste residue in the hole of the brake disc housing 25, as Figures 2 - 4 shown, the slag removal assembly 3 includes a support rod 31 fixedly installed on the workbench 11. A support column 33 is installed at one end of the support rod 31. One end of the support column 33 is movably engaged with the upper surface of the indexing plate 21. Thus, when the indexing plate 21 rotates, the support column 33 remains stationary;

[0035] And a ventilation pipe 35 is fixedly installed at the top end of the support rod 31. The ventilation pipe 35 is horizontally arranged, and a connector 34 is connected to the ventilation pipe 35. The connector 34 is adapted to be connected to an external air compressor to supply air into the ventilation pipe 35. The connector 34 penetrates through the support rod 31 and is fixedly connected to the support rod 31. Fixing disks 32 are connected to both ends of the ventilation pipe 35. Two groups of symmetrically arranged dust blowing parts are installed on the bottom surface of the fixing disk 32. The dust blowing part includes an installation cover 37 fixedly installed on the bottom surface of the fixing disk 32. A cross pipe 38 is fixedly installed inside the installation cover 37. The cross pipe 38 is connected to the ventilation pipe 35 through a hose 36. A plurality of jet nozzles 39 facing the ventilation holes of the brake disc housing 25 are connected to the cross pipe 38;

[0036] Meanwhile, a dust-proof cover 26 is fixedly installed on the bottom surface of the indexing disk 21. The dust-proof cover 26 is inside the workbench 11, and a collection box 27 is placed inside the workbench 11. The collection box 27 is used to collect the blown-off waste residues;

[0037] In this application, a filter screen can be arranged at the top end of the collection box 27 to separate the waste residues and the cutting fluid;

[0038] The external air compressor supplies air to the ventilation pipe 35 through the connector 34. The compressed air is transported to the cross pipe 38 through the hose 36 and then is directionally sprayed to the ventilation holes and other parts of the brake disc housing 25 through a plurality of jet nozzles 39. The waste residues in the holes are blown out by the air flow impact force. When the indexing disk 21 drives the brake disc housing 25 to rotate, the support column 33 is movably engaged with the upper surface of the indexing disk 21 to ensure that the support rod 31 and the ventilation pipe 35 remain stationary, so that the jet nozzles 39 always aim at the target position for continuous purging;

[0039] The blown-off waste residues fall into the collection box 27 inside the workbench 11 along with the air flow. The filter screen at the top end of the collection box 27 can separate the waste residues and the cutting fluid to achieve solid-liquid classification collection. The dust-proof cover 26 prevents the waste residues from splashing onto other components inside the workbench 11, ensuring the safe operation of the equipment, realizing automatic slag removal, and improving the cleaning efficiency and accuracy.

[0040] To sum up: The brake disc housing 25 is sleeved on the top end of the fixed part 22 of the indexing disk 21. The concave hole of the housing is closely attached to the silica gel anti-slip ring at the top end of the fixed part 22 to provide circumferential frictional force. The protruding part 23 of the fixed part 22 is inserted into the through hole of the workbench 11. The silica gel anti-slip layer at the contact position ensures stable plugging and easy disassembly. After receiving the pulse signal, the motor drives the indexing disk 21 to rotate 45° each time. The angle is locked through the cooperation of the positioning pin and the positioning groove of the workbench 11, so that the housing sequentially enters the processing station and the slag removal station.

[0041] When the indexing plate 21 drives the housing to rotate to the slag removal station, the external air compressor supplies air to the air pipe 35 through the connector 34. The compressed air is conveyed to the cross pipe 38 through the hose 36, and then is directed to spray to complex structural parts such as the housing ventilation holes and bolt counterbores through multiple groups of jet nozzles 39. Since the support column 33 is movably engaged with the upper surface of the indexing plate 21, the support rod 31 and the air pipe 35 remain stationary, ensuring that the jet nozzles 39 always aim at the target position. The impact force of the air flow blows out the waste residue in the holes, and the waste residue falls into the collection box 27 in the workbench 11 along with the air flow. The filter screen at the top of the collection box 27 separates the waste residue from the cutting fluid, realizing solid-liquid classification;

[0042] The dust cover 26 prevents the waste residue from splashing onto other components inside the equipment. The indexing plate 21 continues to rotate, driving the housing to circulate between the processing station and the slag removal station until all the processing and cleaning procedures are completed.

[0043] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the technical content disclosed above within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
