Description

Technical Field

[0002] Door rails are an important component of vehicle door systems. They can be divided into window glass rails and door sliding rails. Window glass rails are mainly used to guide the raising and lowering of the window glass, ensuring that the glass moves smoothly up and down.

[0003] The car window glass guide rail mainly consists of a "U"-shaped guide rail body and mounting components. The mounting components are usually stamped "Z"-shaped metal parts, which are typically welded and fixed to the guide rail body as one piece. Mounting holes are drilled on the mounting components, and they are fixed to the reserved holes on the inner panel of the car door with bolts to ensure that the guide rail does not shift during vehicle movement. Therefore, the welding precision of the guide rail body and mounting components is crucial to the reliable use of the car window glass guide rail.

[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0050] Please see Figures 1-4 The present invention provides the following technical solution: a welding fixture for processing door guide rails of new energy vehicles, including a fixture base 1, and further including: a positioning boss 2, a clamping mechanism 3, an installation part positioning and pressing mechanism 4, an X-axis adjustment mechanism 5 and a Y-axis adjustment mechanism 6.

[0051] Furthermore, by Figure 1 As shown, in this embodiment, the positioning boss 2 is fixed to the top surface of the fixture base 1, the guide rail body is upside down on the top of the positioning boss 2, the clamping mechanism 3 is disposed at the top of the positioning boss 2 for clamping the guide rail body, the mounting component positioning and pressing mechanism 4 is movably connected to the fixture base 1 for pressing the mounting component so that the bottom surface of the mounting component is tightly attached to the top surface of the guide rail body, the X-axis adjustment mechanism 5 is drivably connected to the mounting component positioning and pressing mechanism 4 for adjusting the X-axis position of the mounting component positioning and pressing mechanism 4, and the Y-axis adjustment mechanism 6 is drivably connected to the mounting component positioning and pressing mechanism 4 for adjusting the Y-axis position of the mounting component positioning and pressing mechanism 4. With the above scheme, in use, the guide rail body to be welded is first upside down on the top of the positioning boss 2, and then the clamping mechanism 3 is used to clamp it from both ends. The guide rail body ensures its stability and positional accuracy. Then, for the welding position, the X-axis adjustment mechanism 5 adjusts the X-axis position of the mounting component positioning and clamping mechanism 4, and the Y-axis adjustment mechanism 6 adjusts the Y-axis position of the mounting component positioning and clamping mechanism 4. The mounting component positioning and clamping mechanism 4 then positions and fixes the mounting component, ensuring that the bottom surface of the mounting component is tightly fitted to the top surface of the guide rail body. Finally, the mounting component is welded to the guide rail body. In this invention, the guide rail body and the mounting component are positioned and fixed using corresponding clamping structures, ensuring the accuracy of the welding position. Furthermore, both the X-axis and Y-axis positions of the mounting component positioning and clamping mechanism 4 are adjustable, making it suitable for different guide rail bodies or different welding positions. This wide applicability helps improve processing efficiency.

[0052] Optionally, by Figure 1 and Figure 2As shown, in this embodiment, the clamping mechanism 3 includes: a guide slider 31, a clamping block 32, a bidirectional threaded rod 33, and a knob 34. A guide groove 21 is machined on the top of the positioning boss 2. Two guide sliders 31 are symmetrically distributed in the guide groove 21. The clamping block 32 is fixed to the top of the guide slider 31. The bidirectional threaded rod 33 is rotatably installed in the guide groove 21 and passes through the guide slider 31 and is connected to the guide slider 31 by thread engagement. The knob 34 is fixed to one end of the bidirectional threaded rod 33. With the above scheme, when in use, after the guide rail body is upside down on the top of the positioning boss 2, the knob 34 is rotated to make the bidirectional threaded rod 33 rotate, so that the two guide sliders 31 drive the clamping block 32 to move inward under the thread engagement, and the guide rail body is clamped by the two clamping blocks 32.

[0053] Optionally, by Figure 1 and Figure 3 As shown, in this embodiment, the mounting component positioning and clamping mechanism 4 includes: a movable frame 41, positioning clamps 42, positioning pins 43, a first dual-axis cylinder 44, and a mounting component pressure plate 45.

With the above-mentioned solution, the mounting component is placed inside the two positioning blocks 42 during use.

Then, the first dual-axis cylinder 44 is activated, and the piston rod of the first dual-axis cylinder 44 drives the mounting component pressure plate 45 to move down. The mounting component pressure plate 45 presses the mounting component from above, ensuring the stability of the mounting component. At this time, the positioning pin 43 passes through the positioning hole 451, thereby further improving the stability of the mounting component pressure plate 45 and avoiding unnecessary displacement of the mounting component pressure plate 45 during welding.

[0054] Optionally, by Figure 1As shown, in this embodiment, the X-axis adjustment mechanism 5 includes: a movable stage 51, a fixed plate 52, a threaded screw 53, and a drive motor 54.

The threaded screw 53 is rotatably installed between the two fixed plates 52, and the threaded screw 53 passes through the movable stage 51 and is connected to the movable stage 51 by threaded engagement. The drive motor 54 is fixed to the outer wall of the fixed plate 52 and is used to drive the threaded screw 53 to rotate. With the above scheme, when in use, the drive motor 54 is started to drive the threaded screw 53 to rotate. Under the threaded engagement, the movable stage 51 drives the mounting part positioning and pressing mechanism 4 to move, thereby adjusting the X-axis position of the mounting part positioning and pressing mechanism 4.

The piston rod of the horizontal cylinder 62 passes through the mounting frame 61 and is fixedly connected to the movable frame 41. With the above solution, when in use, the horizontal cylinder 62 is activated, and the movable frame 41 is driven to move through the piston rod of the horizontal cylinder 62 to adjust the Y-axis position of the mounting component positioning and pressing mechanism 4.

[0058] Preferably, by Figure 1 and Figure 4As shown, this embodiment also includes a guide rail body clamping mechanism 7.

The second dual-axis cylinder 71 is fixed to the top surface of the fixture base 1, and the guide rail body pressure plate 72 is fixed to the top of the piston rod of the second dual-axis cylinder 71. With the above solution, when in use, the second dual-axis cylinder 71 is started, and the piston rod of the second dual-axis cylinder 71 drives the guide rail body pressure plate 72 to move down, and the guide rail body pressure plate 72 is used to further clamp the guide rail body, thereby helping to further improve the stability of the guide rail body.

[0059] Preferably, by Figure 1 and Figure 4 As shown in this embodiment, the guide rail body clamping mechanism 7 further includes a rubber pad 73. The rubber pad 73 is bonded and fixed to the bottom surface of the guide rail body pressure plate 72. With the above solution, the rubber pad 73 is flexible during use. By clamping the guide rail body with the rubber pad 73, the safety of the guide rail body can be greatly improved, and unnecessary wear on the guide rail body can be avoided.
