Abstract
Description
Technical Field
[0001] This utility model relates to the field of side window processing technology for rail transit vehicles, and specifically to a welding fixture for side windows of rail transit vehicles. Background Technology
[0002] The driver's cab of rail transit vehicles is equipped with left and right side windows on both sides, each including fixed and movable windows. When the vehicle is parked at the platform, the driver can flexibly open the windshield of the movable window to facilitate on-site staff in dispatching and guiding the vehicle, and also to provide the driver with a good view. At the same time, when the side windows are closed, the driver's cab must be kept quiet to avoid noise affecting the driver's operation of the vehicle. Therefore, the quality of the side windows is related to the efficiency and safety of the vehicle operation.
[0003] In related technologies, the current welding process for side windows of rail transit vehicles typically involves using a single resin mold to position the material, then using a fixture to fix it to a welding platform for welding. Furthermore, the fixed and movable windows of the side window require different welding platforms, making the operation cumbersome and inconvenient, resulting in low processing efficiency. Additionally, when welding different positions of the side window, operators need to change welding positions or re-fix the side window, increasing labor intensity and increasing the error associated with repositioning the side window. This can easily cause welding deformation or dimensional deviations, making it impossible to ensure the consistency of the side window welding.
[0004] Therefore, there is an urgent need for a welding fixture for the side windows of rail transit vehicles to avoid welding deformation or dimensional deviation and to improve the ease of operation. Utility Model Content
[0005] The purpose of this utility model is to provide a welding fixture for side windows of rail transit vehicles, so as to solve at least one aspect of the problems and defects mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A welding fixture for side windows of rail transit vehicles, comprising:
[0008] The frame and the tooling body rotatably mounted on the frame;
[0009] The tooling body is provided with a first operating surface and a second operating surface;
[0010] The first operating surface and the second operating surface are respectively provided with mounting slots for processing the left and right side windows of the vehicle.
[0011] The welding fixture for the side windows of rail transit vehicles according to this scheme has at least the following technical advantages:
[0012] This welding fixture for rail transit vehicle side windows allows for precise positioning, processing, and installation of both fixed and movable windows on the left and right sides of the vehicle via mounting slots on the first and second operating surfaces. It eliminates the need for multiple welding platforms, ensuring consistent relative positions of all side window components during welding and preventing deformation and dimensional deviations. Compared to existing welding fixtures for rail transit vehicle side windows, this significantly reduces the probability of welding defects and improves the quality and precision of the finished product. Furthermore, operators no longer need to frequently move their positions or use complex auxiliary tools to adjust welding angles, reducing labor intensity and increasing operational convenience and efficiency.
[0013] As a further embodiment of this utility model: the mounting groove of the first operating surface includes a left fixed window mounting groove and a left movable window mounting groove, and the mounting groove of the second operating surface includes a right fixed window mounting groove and a right movable window mounting groove.
[0014] Because the mounting slots on the first operating surface include a left fixed window mounting slot and a left movable window mounting slot, and the mounting slots on the second operating surface include a right fixed window mounting slot and a right movable window mounting slot, the left fixed window mounting slot and the left movable window mounting slot are used to process the fixed window and the movable window of the left side window of the rail transit vehicle, and the right fixed window mounting slot and the right movable window mounting slot are used to process the fixed window and the movable window of the right side window of the rail transit vehicle. This achieves precise positioning of the side window components. Compared with the existing technology of positioning with a single resin mold, it ensures the consistency of the relative positions of each component of the side window during welding, and avoids deformation and dimensional deviations during welding caused by multiple mold changes and repositioning, thereby improving the quality and precision of the welded product.
[0015] As a further embodiment of this utility model, an isolation ring is provided between the left fixed window mounting slot and the left movable window mounting slot, and between the right fixed window mounting slot and the right movable window mounting slot.
[0016] By setting isolation rings between the left fixed window mounting slot and the left movable window mounting slot, as well as between the right fixed window mounting slot and the right movable window mounting slot, the left fixed window mounting slot and the left movable window mounting slot, as well as the right fixed window mounting slot and the right movable window mounting slot, can be effectively separated and positioned. This ensures that the fixed windows and movable windows of the left and right sides can be welded independently and stably, guaranteeing the reliability of the welding quality of each component.
[0017] As a further improvement of this utility model, an avoidance hole is provided in the middle of the tooling body.
[0018] Because the tooling body has a clearance hole in the middle, workers can more easily install the windshield of the movable window through the clearance hole in the middle of the tooling body. There is no need to remove the movable window from the tooling or make complicated angle adjustments, which reduces the operation steps and improves the accuracy and efficiency of installation.
[0019] As a further embodiment of this utility model: the left fixed window mounting groove and the right fixed window mounting groove are respectively provided with a plurality of first fixing plates around their perimeter, and the left movable window mounting groove and the right movable window mounting groove are respectively provided with a plurality of second fixing plates around their perimeter.
[0020] Since the left and right fixed window mounting slots are respectively equipped with several first fixing plates, and the left and right movable window mounting slots are respectively equipped with several second fixing plates, when the fixed window or movable window is placed in the corresponding mounting slot for processing, the fixed window can be locked in the corresponding mounting slot by locking the fixed window with the first fixing plate or the movable window with the second fixing plate. This can effectively lock the fixed window or movable window in the corresponding mounting slot, prevent shaking or displacement during processing, avoid welding deviation caused by component movement, ensure the uniformity and consistency of welding, and thus improve the processing accuracy of the side windows of rail transit vehicles.
[0021] As a further embodiment of this utility model: a rotating mechanism is provided at each end of the tooling body, and the rotating mechanism is connected to the top of the frame at both ends.
[0022] As a further embodiment of this utility model: the rotating mechanism includes a mounting base and a rotating shaft rotatably disposed within the mounting base, the bottom of the mounting base being connected to the top of the frame.
[0023] As a further embodiment of this utility model: a turntable is provided at one end of the rotating shaft, a plurality of positioning grooves are provided on the turntable, a positioning hole is provided on the mounting base corresponding to the positioning groove, and a positioning pin is provided in the positioning hole.
[0024] Because the tooling body is equipped with rotating mechanisms at both ends, and the rotating mechanisms are connected to the top of the frame at both ends, the rotating mechanisms include mounting bases and rotating shafts rotatably mounted on the mounting bases. The bottom of the mounting bases is connected to the top of the frame, and one end of the rotating shaft is equipped with a turntable with several positioning slots. The mounting bases are equipped with positioning holes corresponding to the positioning slots, and positioning pins are installed in the positioning holes. The mounting bases can be inserted into any one of the positioning slots on the turntable through the positioning pins, so that the tooling body can achieve angular positioning and fixation on the frame after rotation. This makes it easy for operators to weld fixed windows or movable windows at a suitable angle without frequently moving their own position or using complex auxiliary tools to adjust the welding angle, which greatly reduces labor intensity and welding size deviation, and improves welding efficiency and quality.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0038] like Figure 1-3 As shown in the embodiment of this utility model, a welding fixture for side windows of rail transit vehicles includes: a frame 1 and a fixture body 2 rotatably mounted on the frame 1; the fixture body 2 is provided with a first operating surface 21 and a second operating surface 22; the first operating surface 21 and the second operating surface 22 are respectively provided with mounting grooves for processing the left and right side windows of the vehicle.
[0039] Specifically, this rail transit vehicle side window welding fixture rotatably mounts the fixture body 2 onto the frame 1. Through the mounting slots on the first operating surface 21 and the second operating surface 22, it enables precise positioning, processing, and installation of both fixed and movable windows on the left and right sides of the vehicle. This eliminates the need for multiple welding platforms, ensuring the consistency of the relative positions of the various side window components during welding and preventing deformation and dimensional deviations during product welding. Compared to existing rail transit vehicle side window welding fixtures, this significantly reduces the probability of welding defects and improves the quality and precision of the welded product. Furthermore, operators do not need to frequently move their positions or use complex auxiliary tools to adjust the welding angle, reducing labor intensity and improving operational convenience and efficiency.
[0040] Furthermore, the mounting slots of the first operating surface 21 include a left fixed window mounting slot 23 and a left movable window mounting slot 24, and the mounting slots of the second operating surface 22 include a right fixed window mounting slot 25 and a right movable window mounting slot 26.
[0041] Specifically, since the mounting slots of the first operating surface 21 include a left fixed window mounting slot 23 and a left movable window mounting slot 24, and the mounting slots of the second operating surface 22 include a right fixed window mounting slot 25 and a right movable window mounting slot 26, the left fixed window mounting slot 23 and the left movable window mounting slot 24 are used to process the fixed window and movable window of the left side window of the rail transit vehicle, and the right fixed window mounting slot 25 and the right movable window mounting slot 26 are used to process the fixed window and movable window of the right side window of the rail transit vehicle.

[0042] Furthermore, an isolation ring 3 is provided between the left fixed window mounting groove 23 and the left movable window mounting groove 24, and between the right fixed window mounting groove 25 and the right movable window mounting groove 26.
[0043] Specifically, by setting isolation rings 3 between the left fixed window mounting slot 23 and the left movable window mounting slot 24, and between the right fixed window mounting slot 25 and the right movable window mounting slot 26, the left fixed window mounting slot 23 and the left movable window mounting slot 24, as well as the right fixed window mounting slot 25 and the right movable window mounting slot 26, can be effectively separated and positioned, ensuring that the fixed windows and movable windows of the left and right sides can be welded independently and stably, thus guaranteeing the reliability of the welding quality of each component.
[0044] Furthermore, a clearance hole 27 is provided in the middle of the tooling body 2.

The bottom of the mounting base 61 is connected to the top of the frame 1. One end of the rotating shaft 62 is provided with a turntable 63, and the turntable 63 is provided with several positioning grooves 631.
