Technical Field
[0001] This utility model belongs to the field of automobile manufacturing technology, specifically, it relates to a double-headed bolt tightening mechanism for the guide rail of an automobile door module glass lifter. Background Technology
[0002] In the automotive manufacturing industry, the window regulator of the car door module is a key component that ensures the normal raising and lowering of the car door glass and realizes the door sealing and opening functions. As an important part of the window regulator, the installation quality of the guide rail directly affects the stability, smoothness and service life of the window raising and lowering. The double-ended bolt plays a vital connecting role in the fixed installation of the guide rail, and the accuracy and efficiency of its tightening operation has a profound impact on the assembly quality and production progress of the entire car door module.
[0003] Currently, in the tightening of double-ended bolts on the guide rails of automotive door module window regulators, most existing tightening mechanisms require re-clamping and reinstalling the guide rail after it has been fixed. This process is not only cumbersome and time-consuming, but also prone to causing deviations in the installation position of the guide rail due to frequent clamping operations, thus affecting the accuracy of the double-ended bolt tightening position. Therefore, we propose a double-ended bolt tightening mechanism for automotive door module window regulator guide rails. Utility Model Content

The following embodiments are used to illustrate this utility model.
[0015] like Figures 1 to 6As shown, a double-headed bolt tightening mechanism for a car door module window regulator guide rail includes a fixed frame 1. A fixed plate 25 is mounted on the front of the fixed frame 1. An electric cylinder 24 is mounted on the top of the fixed plate 25. The piston rod of the electric cylinder 24 moves through the fixed plate 25. An L-shaped plate 26 is mounted on the bottom of the piston rod of the electric cylinder 24. An electric gun 27 is mounted on the top of the L-shaped plate 26. The output shaft of the electric gun 27 moves through the top of the L-shaped plate 26, and a double-headed bolt tightener 28 is mounted on the bottom of the output shaft of the electric gun 27. Two support plates 2 are arranged below the fixed frame 1. A movable plate 5 is slidably connected to the top of each support plate 2. A connecting plate 13 is mounted on the bottom of the movable plate 5. A connecting frame 10 is installed at the bottom of the support plate 2. A moving groove 16 is opened on the support plate 2. A connecting plate 13 moves through the moving groove. A screw 11 is rotatably connected to the connecting frame 10 through a bearing. The connecting plate 13 is threaded onto the outer wall of the screw 11. A moving plate 6 is slidably connected to the top of the moving plate 5. A moving groove 18 is opened at the bottom of the moving plate 6. A connecting plate 17 is installed at the top of the moving plate 5. The connecting plate 17 is slidably connected to the moving groove 18. A screw 20 passes through the front of the moving plate 6. The screw 20 is rotatably connected to the moving plate 6 through a bearing. A fixing component for fixing the guide rail is provided at the top of the moving plate 6.
[0016] Furthermore, a limiting slide plate 14 is installed at the bottom of the connecting plate 13, and a limiting groove 15 is opened at the bottom of the inner wall of the connecting frame 10. The limiting slide plate 14 and the limiting groove 15 are slidably connected.
[0017] The limiting slide plate 14 and the limiting slide groove 15 can limit the connecting plate 13 and ensure the stability of the connecting plate 13 when it moves.
[0018] Furthermore, a limiting slide plate 22 is installed at the top of the movable plate 5, and a limiting groove 23 is opened at the bottom of the movable plate 6, with the limiting slide plate 22 and the limiting groove 23 slidably connected.
[0019] Among them, by setting the limiting slide plate 22 and the limiting slide groove 23, the moving plate 26 can be limited, ensuring the stability of the moving plate 26 when it moves.
[0020] Furthermore, the fixing component includes a fixing frame 7, an electric cylinder 8 is mounted on the top of the fixing frame 7, the piston rod of the electric cylinder 8 moves through the top of the fixing frame 7, and a pressure plate 9 is mounted on the bottom of the piston rod of the electric cylinder 8.
[0021] Furthermore, a limiting slide plate 29 is installed on the outer wall of the L-shaped plate 26, and a limiting groove 19 is opened on the front of the fixing frame 1. The limiting slide plate 29 and the limiting groove 19 are slidably connected.
[0022] By setting the limiting slide plate 3 29 and the limiting slide groove 3 19, the L-shaped plate 26 can be limited, thereby improving the stability of the L-shaped plate 26 when moving.
[0023] Furthermore, a knob 12 is installed at one end of screw 11, and a knob 21 is installed at one end of screw 20.
[0024] The knobs 12 and 21 are designed to allow personnel to rotate screws 11 and 20 respectively.
[0025] The implementation principle of a double-headed bolt tightening mechanism for a car door module window regulator guide rail is as follows: In use, the guide rail is placed on support plate 2. Then, by activating electric cylinder 8, the pressure plate 9 moves downward, pressing and fixing the guide rail on support plate 2. One end of the double-headed bolt is then installed on the double-headed bolt tightener 28. Depending on the installation position of the double-headed bolt, knob 12 is rotated. Knob 12 rotates screw 11, which in turn moves connecting plate 13 laterally. Connecting plate 13 moves moving plate 5 laterally, and moving plate 5, through connecting plate 27, moves moving plate 26 laterally. This allows adjustment of the lateral position of the guide rail on moving plate 26. Then, knob 12 is rotated, which rotates screw 20, which moves moving plate 26 longitudinally, allowing adjustment of the lateral position of the guide rail on moving plate 26. The longitudinal position of the guide rail is determined by the second plate 26. Then, the electric cylinder 24 and the electric gun 27 are activated. The electric gun 27 drives the double-ended bolt to rotate through the double-ended bolt tightener 28. The electric cylinder 24 drives the L-shaped plate 26 to move downward, and the L-shaped plate 26 drives the electric gun 27 to move downward, so that the electric gun 27 drives the double-ended bolt to screw into the installation position through the double-ended bolt tightener 28, thereby completing the tightening operation of the guide rail double-ended bolt. With the above structure, it is convenient for personnel to adjust the relative position between the guide rail and the double-ended bolt tightener 28 after the guide rail is fixed, ensuring the accuracy of the double-ended bolt tightening position, and greatly improving the tightening and installation efficiency of the guide rail double-ended bolt. This solves the problem that in the existing guide rail double-ended bolt tightening mechanism, when the double-ended bolt needs to be tightened at different positions after the guide rail is fixed, the guide rail needs to be re-clamped and installed, which makes the operation more complicated and affects the tightening and installation efficiency of the double-ended bolt.
