Description

Technical Field

[0001] The invention relates to the technical field of vehicle body processing, and in particular to a vehicle window opening method based on vehicle body processing. Background Art

[0002] EMU, or power vehicle, refers to vehicles equipped with power devices in rail transit systems, including locomotives and power cars. EMUs are equipped with driving wheels, while the corresponding vehicles without driving devices are trailers. For a train to run normally on the track, it must have an EMU to provide sufficient traction for the entire train, but it does not need to be attached to a trailer without power.

[0003] When processing the windows of high-speed railways, motor vehicles and passenger cars, multiple milling processes are required and they cannot be formed in one go. Manual assistance is required in the later stage, which makes the processing method more complicated and inefficient, inconvenient for staff to use, and has certain limitations. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the shortcomings of the prior art, the present invention provides a vehicle window opening method based on vehicle body processing, which has the advantage of being convenient for the online or finished vehicle modification and remanufacturing of high-speed railways, EMUs, and trains (passenger cars), and solves the problem that the existing railway high-speed railway, EMU and passenger car window processing requires multiple milling and cannot be formed in one time, and manual assistance is required in the later stage, resulting in the processing method being cumbersome and inefficient.

[0005] (II) Technical solution To achieve the above object, the present invention provides the following technical solution: a vehicle window opening method based on vehicle body processing, comprising the following steps: S1: Determine the location of the positioning hole according to the reference; S2: After the opening positions are determined, use the template to open the holes for the windows; S3: Align the positioning holes of the bottom plate with the positioning holes on the carriage to determine the position, and fix the entire positioning plate to the carriage wall; S4: Fix the window opener; S5: According to the positioning holes, adjust the beam to the position of the large window arc, find the positioning holes drilled in advance, adjust the milling cutter to the corresponding position through the cutter head telescopic device, start milling after confirmation, and process the remaining three arcs in sequence; S6: According to the positioning holes, adjust the window opener to a horizontal position, find the pre-punched positioning holes, fix the beam, adjust the telescopic devices of the horizontal and vertical cutter heads to the corresponding positions, and perform horizontal and vertical milling after confirmation. After milling, rotate the window opener beam 180° to mill the remaining two frames; S7: Remove the window opening machine and manually process and polish the remaining edges and corners; S8: Complete the window opening operation.

[0006] In some embodiments, when milling the horizontal and vertical frames in S6, the remaining 100 mm distance is not milled to prevent vibration during subsequent processing of the window opening machine, thereby affecting the accuracy.

[0007] In some embodiments, the grinding mechanism in S7 is an angle grinder.

[0008] In some embodiments, in S6, position adjustment is performed through transverse and longitudinal guide screw mechanisms.

[0009] In some embodiments, the milling structure in S5 and S6 is a rod milling cutter.

[0010] In some embodiments, the rod milling cutter is installed on a transverse power head, a longitudinal power head and an arc power head respectively.

[0011] (III) Beneficial effects Compared with the prior art, the present invention provides a vehicle window opening method based on vehicle body processing, which has the following beneficial effects: The present invention installs the mobile processing equipment on the body of the manufactured high-speed railway, motor vehicle and passenger car to ensure the stable connection between the mobile equipment and the body; ensures the processing accuracy, and can complete the two steps of straight line processing and curve processing in one installation, which is energy-saving, time-saving, green, and shortens the processing time. The power used is 1 / 10 of that of a large-scale professional processing machine, and no transportation is required, and the processing problems are solved on the spot and in situ; the equipment structure design is simplified, compact, fully functional, and reliable to install; high-speed railways, motor vehicles, and trains (passenger cars) use aluminum profiles, and in order to ensure the strength of the car body, there will be oblique reinforcement connections in the middle of the aluminum profiles. This equipment is light in weight and ensures that the car body will not be damaged. It has the advantage of being convenient for high-speed railways, motor vehicles, trains (passenger cars) to be transformed and remanufactured online or on finished cars, and solves the problem that the windows of existing railway high-speed railways, motor vehicles and passenger cars need to be milled multiple times during processing, cannot be formed in one time, and need manual assistance in the later stage, resulting in its processing method being cumbersome and inefficient.
