Description

Technical Field

[0001] This utility model belongs to the field of automotive lighting technology, specifically relating to a position adjustment mechanism for a through-type taillight mounting nut. Background Technology

[0002] The function of the online dimensional inspection equipment for automotive taillights is to perform 100% full inspection of the taillight dimensions. The data measured by the equipment needs to be compared with the data from the coordinate measuring machine and the inspection fixture, and the measurement data of the three need to meet certain tolerance requirements. In order to achieve the above functional requirements, the way the online inspection equipment fixes the taillights needs to be consistent with the inspection fixture, which includes tightening the taillight mounting nuts. An example of application is to use a screwdriver or motor to tighten the taillight mounting nuts.

[0003] To accommodate the deformation of the continuous taillight and its impact on vehicle installation, the taillight mounting nuts are typically designed with a movable structure. This means the mounting nut's position on the taillight is not fixed and allows for some displacement. Currently, due to the non-fixed position of the mounting nut, misalignment occurs. If the position is completely outside the tightening range of a screwdriver or motor, the mounting nut will fail to tighten completely. Alternatively, if the misaligned position of the mounting nut is still within the normal tightening range of a screwdriver or motor, but the position of the screwdriver or motor tightening mechanism is usually fixed, there will still be a positional difference and coaxiality difference between the two. Tightening under these circumstances will cause the taillight to deform and twist, or the actual position of the taillight to be misaligned by the screwdriver, thus adversely affecting the measurement results. Utility Model Content

[0004] The purpose of this utility model is to provide a through-type taillight mounting nut position adjustment mechanism to solve the technical problem that the mounting nut may shift, causing the screwdriver to be unable to tighten the nut or the taillight to deform after tightening, thus affecting the accuracy of taillight size measurement. The mechanism achieves the goal of using a magnet to attract the nut to the coaxial position with the screwdriver, so that the screwdriver can accurately screw the nut into the taillight, avoiding taillight deformation and improving taillight measurement accuracy.

[0005] To solve the above-mentioned technical problems, this utility model provides a position adjustment mechanism for a through-type taillight mounting nut, comprising:

[0006] A taillight, wherein a nut is movably disposed on the side wall of the taillight, and the nut is movable in the horizontal direction;

[0007] A tightening assembly is provided at the end of the taillight. The tightening assembly includes: a first cylinder and an electric screwdriver connected to the output shaft of the first cylinder; the first cylinder is used to drive the electric screwdriver to move in a horizontal direction, and the electric screwdriver is detachably connected to the nut.

[0008] A positioning component is disposed on the side wall of the taillight. The positioning component includes: a second cylinder, a sliding member connected to the output shaft of the second cylinder, and a magnet disposed on the sliding member; the second cylinder is used to drive the sliding member to move in a horizontal direction, and the magnet is magnetically attracted to the nut.

[0009] Furthermore, the positioning component also includes: a vertically arranged second support frame, a positioning block horizontally arranged at the top of the second support frame, and a plurality of horizontal through holes opened on the positioning block, wherein the end of the electric screwdriver near the taillight passes through the through holes and the nut in sequence.

[0010] Furthermore, two positioning components are provided, each positioned on one side of the taillight, and the two positioning blocks abut against the two side walls of the taillight.

[0011] Both the sliding member and the second cylinder are located on the positioning block away from the tightening assembly, and both the sliding member and the second cylinder are located on the end face of the positioning block away from the taillight.

[0012] Furthermore, the axes of the nut, the electric screwdriver, and the magnet are all located on the same horizontal plane, with the electric screwdriver and the magnet located on opposite sides of the nut.

[0013] The electric screwdriver rotates to fix the nut, and the magnet attracts the nut to move horizontally.

[0014] Furthermore, a limiting block is sleeved on the outside of the nut. The limiting block is U-shaped, and the vertical ends of the nut abut against the vertical ends of the limiting block.

[0015] The end of the nut abuts against the positioning block.

[0016] Furthermore, the tightening assembly also includes a vertically arranged first support frame, the top of which is connected to the first cylinder.

[0017] Furthermore, it also includes: a measuring component, the measuring component being disposed on the side wall of the taillight, the measuring component comprising: a vertically arranged third support frame, a displacement sensor connected to the top end of the third support frame, and a driving component connected to the bottom end of the third support frame;

[0018] The displacement sensor is used to measure the dimensions of the third support frame, and the drive assembly is used to drive the displacement sensor to move to the taillight.

[0019] Furthermore, it also includes a horizontally arranged workbench, with the bottom ends of the first support frame, the second support frame, and the third support frame all connected to the top end of the workbench.

[0020] The beneficial effects of this utility model are:

[0021] This invention, by setting a positioning component, limits the vertical displacement of the nut. The maximum displacement of the magnet pushed by the second cylinder is set to be coaxial with the position where the nut needs to be installed. The second cylinder horizontally pushes the sliding component and the magnet to attract the nut and move it horizontally. After the nut reaches the installation position, the first cylinder pushes the electric screwdriver to tighten the nut. The second cylinder then drives the sliding component and the magnet back to their original positions, completing the nut fixing of the taillight. This ensures the coaxiality of the nut and screwdriver, guaranteeing a tight fixing effect and preventing deformation of the taillight caused by misaligned nuts pressing on it during tightening.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] Example 1:

[0036] like Figures 1 to 8 As shown, a position adjustment mechanism for a through-type taillight mounting nut includes: a taillight 1, a tightening component 2, a positioning component 3, a measuring component 4, and a worktable 5. The worktable 5 is horizontally arranged, and the taillight 1, tightening component 2, positioning component 3, and measuring component 4 are all mounted on the worktable 5. The tightening component 2 is used to tighten and fix the taillight 1 to facilitate subsequent measurement by the measuring component 4. The taillight 1 is mounted on the positioning component 3 for positioning to prevent slippage and displacement during the tightening process of the tightening component 2, which would affect the tightening accuracy.

[0037] The taillight 1 has a nut 11 movably mounted on its side wall, which can move horizontally. A limiting block 12 is fitted on the outside of the nut 11. The limiting block 12 is U-shaped, and the vertical ends of the nut 11 abut against the vertical ends of the limiting block 12. In order to accommodate the deformation of the through taillight 1 and its impact on vehicle installation, the mounting nut 11 of the taillight 1 is usually designed as a movable structure, that is, the mounting position of the mounting nut 11 on the taillight 1 is not fixed and has a certain displacement. The limiting block 12 restricts the vertical movement of the nut 11 and leaves a certain displacement in the horizontal direction, that is, the nut 11 can move horizontally.

[0038] like Figure 3As shown, the tightening assembly 2 is located at the end of the taillight 1. The tightening assembly 2 includes: a vertically arranged first support frame 21, the bottom end of which is connected to the top end of the workbench 5, and a first cylinder 22 connected to the top end of the first support frame 21. The output shaft of the first cylinder 22 is connected to an electric screwdriver 23. The first cylinder 22 is used to drive the electric screwdriver 23 to move in the horizontal direction. The electric screwdriver 23 is detachably connected to the nut 11. After being powered on, the electric screwdriver 23 rotates to fix the nut 11. The axis of the electric screwdriver 23 and the axis of the nut 11 are located on the same horizontal plane. When the nut 11 reaches the installation position, the first cylinder 22 drives the electric screwdriver 23 to approach and insert into the nut 11 and tighten the nut.

[0039] like Figure 4 As shown, the positioning component 3 is located on the side wall of the taillight 1. The positioning component 3 includes: a vertically arranged second support frame 31, the bottom end of which is connected to the top end of the workbench 5, and a positioning block 32 is horizontally arranged on the top end of the second support frame 31; there are two positioning components 3, which are respectively located on both sides of the taillight 1, and the two positioning blocks 32 respectively abut against the side walls of the taillight 1, and the end of the nut 11 abuts against one of the positioning blocks 32; the taillight 1 is clamped in the two positioning components 3 and the positioning blocks 32 position it to prevent the taillight from shifting during the process of the electric screwdriver 23 tightening the nut 11, which would cause the nut 11 to not be tightened.

[0040] The positioning block 32 has multiple horizontal through holes. The end of the electric screwdriver 23 near the taillight 1 passes through the through holes and the nut 11 in sequence. The axis of the through hole and the axis of the nut 11 are on the same horizontal plane. After the electric screwdriver 23 is inserted into the through hole and the nut 11 in sequence, the nut 11 is tightened.

[0041] like Figure 5 As shown, a sliding member 33 and a second cylinder 35 are connected to the positioning block 32 away from the tightening component 2. Both the sliding member 33 and the second cylinder 35 are located on the end face of the positioning block 32 away from the taillight 1. The output shaft of the sliding member 33 and the second cylinder 35 are connected. A magnet 34 is provided on the sliding member 33. The axis of the magnet 34 and the axis of the nut 11 are on the same horizontal plane. The magnet 34 and the nut 11 are magnetically attracted. The second cylinder 35 is used to drive the sliding member 33 and the magnet 34 to move horizontally. The magnet 34 is used to attract the nut 11 to move horizontally. By setting the maximum displacement of the magnet 34 pushed by the second cylinder 35 to be coaxial with the position where the nut 11 needs to be installed, when the second cylinder 35 reaches its maximum position, the magnet 34 will move the nut 11 to the installation position.

[0042] Meanwhile, the electric screwdriver 23 and the magnet 34 are located on both sides of the taillight 1. So the magnet 34 on one side of the taillight 1 drives the magnet 34 to attract the nut 11 to the installation position. The electric screwdriver 23 on the other side of the taillight 1 passes through the through hole of the positioning block 32 and tightens the nut 11.

[0043] Example 2:

[0044] like Figure 6 As described in Embodiment 1, the measuring component 4 is located on the side wall of the taillight 1. The measuring component 4 includes: a vertically arranged third support frame 41, the bottom end of which is connected to the workbench 5, a displacement sensor 42 connected to the top end of the third support frame 41, and a driving component 43 connected to the bottom end of the third support frame 41. The displacement sensor 42 is used to measure the size of the third support frame 41, and the driving component 43 is used to drive the displacement sensor 42 to move to the taillight 1. After the tightening component 2 and the positioning component 3 tighten and fix the nut 11 and the taillight 1, the driving component 43 drives the third support frame 41, thereby driving the displacement sensor 42 to the taillight 1, and the displacement sensor 42 measures the size of the taillight 1.

[0045] Example 3:

[0046] Based on Example 1, the same number of nuts 11, electric screwdrivers 23 and magnets 34 are provided. The axes of the multiple nuts 11, electric screwdrivers 23 and magnets 34 are located on the same horizontal plane. After the magnets 34 attract the nuts 11 to the loading position, the electric screwdrivers 23 tighten and fix the nuts 11, which facilitates the subsequent measurement by the measuring component 4.

[0047] In summary, after the taillight 1 is clamped by the positioning component 3, the second cylinder 35 pushes the sliding component 33, thereby driving the magnet 34 to move horizontally. During the movement of the magnet 34, the displaced nut 11 is attracted. The magnet 34 drives the nut 11 to continue moving horizontally. When the second cylinder 35 reaches its maximum stroke, the magnet 34 attracts the nut 11 to the loading position. The first cylinder 22 pushes the electric screwdriver 23 close to the nut 11. The electric screwdriver 23 is inserted into the positioning block 32 and the nut 11 in sequence. The electric screwdriver 23 rotates to tighten the nut 11 and fix the taillight 1. At this time, the second cylinder 35 drives the sliding component 33 to return to its original position, and the first cylinder 22 drives the electric screwdriver 23 to return to its original position. The drive component 43 drives the displacement sensor 42 to the taillight 1 to measure the taillight 1.
