Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile accessories, in particular to a checking tool for repairing an automobile limiter. Background Art
[0002] In the automotive coating process manufacturing, the accompanying fixture is a necessary auxiliary equipment for the mechanized transportation system of the coating line and the operation of each workstation. The purpose is to keep the car door open at a certain degree, facilitate operation when flowing on the line, and avoid production accidents caused by the swing of the car door, avoid collisions between the spraying parts, and reduce the cost of later repair and rework. Therefore, the loose limiter has the following adverse effects: the car door is scrapped, scratched, and has color difference. The loose door limiter will cause the door to close automatically, resulting in a collision between the robot and the car door, causing equipment damage, scrapped car doors, and other defects. At present, there is no high-precision inspection fixture, and it is impossible to make pre-judgment and repair.
[0003] The working principle of the limiter and the anatomy of the fixture structure are as follows: The commonly used limiter is the limit box type, see Figure 1 , Figure 1 It is a schematic diagram of the structure of the limiter in the prior art; its working principle is: the limiter bracket is fastened to the car body by 1 mounting bolt, the limit box is fastened to the car door by 2 mounting screws, and when the door is opened, the limit box will move along the limit arm. The clamp is shown in Figure 1, and the clamp includes a bracket 1 connected to the car body side, a movable limit pull rod 2, a screw 3 connected to the car door, a cover plate 4 connected to the car door by screws, a first-level limit gear 5 (door fully open state), a sliding roller 6, a second-level gear 7 (door closed state), and a tension spring 8. The clamp is connected to the car body side by connecting the bracket 1, and the clamp is connected to the car door by connecting the screw 3. The entire clamp pulls the sliding roller 6 around the hinge axis through the pull rod 2 to rotate to realize the door opening and closing actions. The force of the tension spring forms a holding force in the grooves of the first-level limit gear 5 and the second-level limit gear 7 to prevent the door from moving, thereby achieving the purpose of positioning and limiting.
[0004] As the number of cycles increases, Figure 1 The connection bracket 1 will be deformed due to stress, resulting in an increase in the included angle and a shortened pull-out length of the overall pull rod, which will cause the sliding roller 6 to be unable to completely engage in the primary limit stop 5. During the production and flow of the vehicle body, the limiter cannot play a good limiting role. During the high-speed operation of the vehicle body, the door position will fluctuate because the sliding roller 6 is separated from the limit stop 5, causing the door closing limit to fail, resulting in a collision between the manipulator and the door, causing equipment damage, door scrapping and other defects.
[0005] The applicant has found that the prior art has at least the following technical problems: the existing detection and repair means is to place the limiter on a detection table during detection and measure it with a measuring instrument such as a vernier caliper. Because it is not a dedicated detection table for the limiter, its adaptability is poor and it takes a long time to fix. Utility Model Content

In the description of the present invention, unless otherwise specified, "multiple" means two or more.
[0029] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0030] The commonly used limiter is the limit box type, see Figure 1 , Figure 1It is a schematic diagram of the structure of the limiter in the prior art; its working principle is: the limiter bracket is fastened to the car body by 1 mounting bolt, the limit box is fastened to the car door by 2 mounting screws, and when the door is opened, the limit box will move along the limit arm. The clamp is shown in Figure 1, and the clamp includes a bracket 1 connected to the car body side, a movable limit pull rod 2, a screw 3 connected to the car door, a cover plate 4 connected to the car door by screws, a first-level limit gear 5 (door fully open state), a sliding roller 6, a second-level gear 7 (door closed state), and a tension spring 8. The clamp is connected to the car body side by connecting the bracket 1, and the clamp is connected to the car door by connecting the screw 3. The entire clamp pulls the sliding roller 6 around the hinge axis through the pull rod 2 to rotate to realize the door opening and closing actions. The force of the tension spring forms a holding force in the grooves of the first-level limit gear 5 and the second-level limit gear 7 to prevent the door from moving, thereby achieving the purpose of positioning and limiting.
[0031] As the number of cycles increases, Figure 1 The connection bracket 1 will be deformed due to stress, resulting in an increase in the included angle and a shortened pull-out length of the overall pull rod, which will cause the sliding roller 6 to be unable to completely engage in the primary limit stop 5. During the production and flow of the vehicle body, the limiter cannot play a good limiting role. During the high-speed operation of the vehicle body, the door position will fluctuate because the sliding roller 6 is separated from the limit stop 5, causing the door closing limit to fail, resulting in a collision between the manipulator and the door, causing equipment damage, door scrapping and other defects.
[0032] In view of the above problems, an embodiment of the utility model provides a checking fixture for repairing a vehicle limiter, which can fix and repair the limiter and improve the repair efficiency.
