Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, and in particular to a repair device for automobile parts production and processing. Background Art

[0002] Brake discs, as an indispensable core component in the automotive braking system, play a key role in efficiently converting the kinetic energy of the vehicle into heat energy during driving, thereby ensuring that the vehicle can decelerate smoothly until it stops safely. In the process of producing brake discs, a series of sophisticated process steps are indispensable, which covers four stages: raw material preparation, casting, processing and heat treatment. Especially in the processing stage, the brake disc needs to undergo multiple processes such as turning, drilling, and milling to remove surface defects and ensure the accuracy of size and shape. Among them, the drilling operation is based on the assembly specifications, and the standard aperture mounting holes are accurately drilled to adapt to standard bolts and nuts to achieve a stable connection.

[0003] However, in the face of non-standard requirements or special application scenarios, standard aperture mounting holes are often not up to the task. At this point, it is necessary to perform secondary processing on brake discs with standard apertures. Especially in situations where additional assembly clearance is required to ensure the assembly effect, or where the brake disc needs to withstand greater loads and higher temperatures (during the braking process, the brake disc not only carries a huge mechanical load, but also generates a large amount of heat energy. If the heat cannot be dissipated in time, the temperature of the brake disc will rise, threatening braking performance and driving safety), secondary hole expansion processing of the brake disc mounting holes becomes necessary. By expanding the hole, both the assembly clearance and the heat dissipation area can be increased, perfectly adapting to various special needs.

[0004] Most traditional hole-expanding equipment is simple in design and relies on manual operation of parts, which is not only labor-intensive but also inefficient. Although some advanced equipment, such as the Chinese patent CN115781297A, achieves stable hole expansion by fixing parts, effectively reducing the labor burden, it still requires manual installation and disassembly during the processing, making it difficult to achieve seamless connection with the front-end brake disc automated production line, thus limiting the improvement of overall processing efficiency.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The present invention Figure 1-Figure 7 As shown, it is a refurbishment device for automobile parts production and processing.

This embodiment takes the setting of one group of reaming mechanisms 2 as an example.

[0034] Further Figure 1 and Figure 2 As shown, the above-mentioned conveying mechanism 1 includes a three-dimensional conveyor line bracket 11, the bottom of the conveyor line bracket 11 is installed at the corresponding position of the production line, an active roller 13 is rotatably arranged on one side of the top of the conveyor line bracket 11, and a driven roller 19 is rotatably arranged on the other side, a conveyor belt 14 is transmitted between the active roller 13 and the driven roller 19, and the conveyor belt 14 is provided with two groups, which are separated at both ends of the active roller 13 and the driven roller 19, and a conveying motor 12 is also arranged on the conveyor line bracket 11 near one end of the active roller 13, and the output shaft of the conveying motor 12 is connected to the active roller 13, driving the active roller 13 to rotate, thereby driving the conveyor belt 14 to transmit.

[0035] Furthermore, the surfaces of the two groups of conveyor belts 14 are equipped with multiple groups of receiving bases 15, which are evenly spaced and used to receive the brake discs 100 processed at the upper end, and then convey them to the lower end process after secondary processing of hole expansion by the hole expansion mechanism 2.

[0036] Specific as Figure 2 As shown, a receiving groove is provided on the top surface of the receiving base 15, and the receiving groove is an arc-shaped limiting arc groove 16 at both longitudinal ends of the receiving base 15, which is roughly limited in coordination with the outer shape of the brake disc 100, and a first limiting column 17 is further provided at the bottom center of the receiving groove, and second limiting columns 18 are symmetrically provided on both longitudinal sides of the first limiting column 17.

The moving gear 320 is driven to rotate by the moving motor 32, and the moving gear 320 drives the first moving rack 38 and the second moving rack 39 to move toward each other, thereby driving the moving seats 35 at both ends to move toward each other, thereby realizing the functions of clamping and releasing.

[0041] Further Figure 6As shown, auxiliary rollers 311 are rotatably arranged at the upper and lower ends of the connecting shaft tube 310 near the moving gear 320. The two auxiliary rollers 311 are respectively adapted to the first moving rack 38 or the second moving rack 39 on the corresponding side.

The primary gear 49 is meshed with the secondary gear 410, and the primary gear 49 is larger than the secondary gear 410. The rotation speed of the hole expansion processing is increased through the gear transmission ratio. Further, a driving motor 48 is arranged at the bottom of the mounting box 47. The output shaft of the driving motor 48 passes through the mounting box 47 and is connected to the rotating shaft one.

The rotating spindle 45 drives the driving cylinder 46 to rotate, thereby driving the reaming drill 412 to rotate around the central axis hole of the brake disc 100, rotates to a set angle, and aligns the next mounting hole. The driving cylinder 46 is started again to drive the reaming drill 412 to move downward for processing, and this process is repeated until all the mounting holes are reamed. Then the moving motor 23 is started to drive the clamping assembly 3 to move downward, and the processed brake disc 100 is placed in the corresponding receiving base 15. The moving motor 32 is started to drive the first moving rack 38 and the second moving rack 39 to move outward, releasing the brake disc 100, and the brake disc 100 continues to be transported to the next process.
