Description

Technical Field

[0001] The utility model belongs to the technical field of automobile side skirt trim detection, and particularly relates to a fixture for detecting an automobile side skirt trim. Background Technique

[0002] The automobile side skirt trim is a skirt board installed on both sides of the vehicle body, mainly used to reduce the airflow on both sides of the vehicle body from entering the vehicle body, thereby reducing the reverse airflow generated during vehicle driving. During the production and processing of the automobile side skirt trim, appearance, dimensions, etc. need to be detected. During the detection of the automobile side skirt trim, a corresponding fixture for detecting the automobile side skirt trim is required to clamp and assist in detecting the automobile side skirt trim.

[0003] The Chinese utility model patent with the patent number: CN217716185U discloses a fixture for detecting an automobile side skirt trim. This application points out that when the existing fixture for detecting an automobile side skirt trim is in use, it is not convenient to adjust the angle and position of the side skirt trim, resulting in low detection efficiency, and discloses a fixture for detecting an automobile side skirt trim, including a cylinder body. A connecting frame is arranged on the top surface of the cylinder body. Electric push rods are arranged on both sides of the connecting frame. A supporting plate is arranged on the top surface of the connecting frame. Electric suction cups are arranged on both sides of the connecting frame. The electric suction cups are located below the convex plate. The electric push rods and the electric suction cups are staggered from each other. A motor is arranged inside the cylinder body. The output shaft of the motor is fixedly connected with a transmission gear. A crown gear is meshed and driven on the side wall of the transmission gear. A screw rod is fixedly connected to the top surface of the crown gear. A threaded cylinder is arranged on the side wall of the screw rod. In the utility model, the angle and position of the placed side skirt trim can be adjusted so as to detect the side skirt trim through the fixture.

[0004] Combined with the content recorded in the specification and the specification drawings, it can be seen that in this application, during use, the side skirt trim to be detected is mainly supported by the supporting plate and the convex plate, and the convex plate sucks the side skirt trim under negative pressure through the cooperation of the electric suction cup, the suction pipe and the suction port to realize the fixation of the side skirt trim. And during use, the detection angle of the side skirt trim is adjusted by controlling the movement of the supporting plate through the electric push rod and the telescopic rod.

[0005] However, since the outer surface of the automobile side skirt trim is mostly a curved surface, the external dimensions will vary to a certain extent depending on the type of the automobile, and it has the characteristic that the length is greater than the width in terms of dimensions. This makes the effect of fixing and limiting the automobile side skirt trim by negative pressure adsorption poor. At the same time, when the angle of the supporting plate is adjusted, the automobile side skirt trim will also slide or even fall due to its own gravity, resulting in poor stability of the clamping and limiting of the automobile side skirt trim on the automobile side skirt trim.

[0006] Therefore, in view of the above technical problems, it is necessary to provide a fixture for detecting an automobile side skirt trim.

[0007] The information disclosed in this background art section is only intended to enhance the overall understanding of the background of the present utility model and should not be regarded as an admission or any form of implication that this information constitutes prior art already known to those of ordinary skill in the art.

The supporting sliders 202 play a role in supporting and fixing the anti-slip clamping plates 201, and the anti-slip clamping plates 201 are synchronously moved and controlled by moving and controlling the supporting sliders 202.

[0038] As Figures 2 to 3 shown, a driving rotating shaft 203 is threadedly connected between a pair of supporting sliders 202. The driving rotating shaft 203 plays a role in supporting, limiting and moving control of a pair of supporting sliders 202, and a pair of supporting sliders 202 are moved and controlled by driving the driving rotating shaft 203 to rotate.

[0040] It should be noted that external threads with opposite rotation directions are opened on both sides of the driving rotating shaft 203, and internal threads with the same rotation direction are opened in a pair of supporting sliders 202. It is convenient to make a pair of supporting sliders 202 move in opposite directions along with the rotation of the driving rotating shaft 203 under the action of the internal and external threads, so as to facilitate driving a pair of anti-slip clamping plates 201 to perform centering clamping on the automobile side skirt trim.

[0043] Specifically, the side of the limiting boss 305 away from the auxiliary supporting plate 301 is arc-shaped. The auxiliary supporting plate 301 is assembled and limited by assembling and limiting the limiting boss 305.

[0044] As Figures 4 to 5 shown, a pair of control air cylinders 302 are fixedly assembled on the opposite sides of a pair of anti-slip clamping plates 201. The control air cylinders 302 play a role in storing and moving and limiting the limiting ejector rods 303.

[0045] As Figures 4 to 5As shown, a limiting ejector rod 303 is slidably assembled in each of the pair of control air cylinders 302. The limiting ejector rod 303 plays a role in supporting, limiting, and moving control of the friction locking block 304.

[0046] As Figures 4 to 5 shown, at one end of the limiting ejector rod 303 outside the control air cylinder 302, a friction locking block 304 is fixedly connected. The friction locking block 304 is arranged in cooperation with the auxiliary supporting plate 301. The auxiliary supporting plate 301 is locked and limited by the way that the friction locking block 304 contacts the arc-shaped side surface of the limiting convex platform 305, so that the auxiliary supporting plate 301 can be fixed at different angles.

[0047] Specifically, assembly avoidance grooves are formed on the opposite sides of the pair of anti-slip clamping plates 201, and the pair of auxiliary supporting plates 301 are fixedly assembled in the assembly avoidance grooves. The assembly avoidance grooves provide an assembly and operation space for the control air cylinder 302 and the compressed air storage cylinder 306.

[0048] As Figures 4 to 5 shown, a compressed air storage cylinder 306 is fixedly assembled in the assembly avoidance groove, and the compressed air storage cylinder 306 is arranged between the pair of control air cylinders 302. The compressed air storage cylinder 306 plays a role in gas storage, and air gas is conveyed into the control air cylinder 302 by compressing the gas in the compressed air storage cylinder 306.

[0049] As Figures 4 to 5 shown, a compression piston block 307 is slidably assembled in the compressed air storage cylinder 306. The compression of the gas in the compressed air storage cylinder 306 is controlled by controlling the movement of the compression piston block 307.

[0050] As Figures 4 to 5 shown, a moving screw rod 308 is rotatably connected to one end of the compression piston block 307 away from the anti-slip clamping plate 201. The movement of the compression piston block 307 is controlled by the moving screw rod 308.

[0051] Specifically, the moving screw rod 308 passes through the compressed air storage cylinder 306, and the moving screw rod 308 is threadedly connected to the compressed air storage cylinder 306. By controlling the rotation of the moving screw rod 308, the moving screw rod 308 can drive the compression piston block 307 to slide in the compressed air storage cylinder 306 under the action of internal and external threads.

[0052] As Figures 4 to 5 shown, a rotating end head 309 is fixedly connected to one end of the moving screw rod 308 outside the compressed air storage cylinder 306. The moving screw rod 308 is rotationally driven by controlling the rotation of the rotating end head 309.

[0053] As Figures 4 to 5As shown, a pair of communicating air pipes 310 are fixedly connected to the outside of the compression air reservoir 306, and the pair of communicating air pipes 310 are arranged on the side of the compression piston block 307 away from the moving screw 308, and the two ends of the pair of communicating air pipes 310 are respectively connected to the compression air reservoir 306 and the control air cylinder 302. The communicating air pipe 310 serves to connect the compression air reservoir 306 with the control air cylinder 302, so as to facilitate the gas in the compression air reservoir 306 to be transported to the control air cylinder 302 along the communicating air pipe 310, thereby facilitating the movement control of the limit push rod 303.

[0054] like Figures 4 to 5 As shown, one end of a pair of limiting push rods 303 located in the control gas cylinder 302 is fixedly connected to a driving piston block 311. The driving piston block 311 can drive the limiting push rod 303 to extend under the action of gas pressure through the sliding cooperation between the driving piston block 311 and the control gas cylinder 302.

[0055] like Figures 4 to 5 As shown, a connecting spring 312 is fixedly connected between the driving piston block 311 and the control cylinder 302. The connecting spring 312 supports and resets the driving piston block 311 through its expansion and contraction and reset.

[0056] During specific use, after placing the automobile side skirt trim on the supporting plate 101, the driving shaft 203 is driven to rotate by controlling the rotation of the adjusting hand wheel 205, and a pair of supporting sliders 202 drive a pair of anti-slip plywood 201 to move in opposite directions under the action of internal and external threads, and the automobile side skirt trim placed on the supporting plate 101 is clamped and limited by a pair of anti-slip plywood 201.

[0057] At the same time, according to the outer surface of the side skirt trim of the automobile, the auxiliary support plate 301 can be rotated to allow the auxiliary support plate 301 to perform auxiliary support and limit on the side of the side skirt trim of the automobile. When the auxiliary support plate 301 is adjusted, the movable screw 308 is driven to rotate by controlling the rotation of the rotating end 309, so that the movable screw 308 drives the compression piston block 307 to slide in the compression air storage cylinder 306 under the action of the internal and external threads, so that the gas in the compression air storage cylinder 306 can be compressed by the compression piston block 307. The lower edge connecting air pipe 310 is transported into the control air cylinder 302, and the driving piston block 311 drives the limiting push rod 303 and the friction locking block 304 to move under the action of gas pressure by transporting gas into the control air cylinder 302, so that the auxiliary supporting plate 301 is locked and positioned by the mutual interference between the friction locking block 304 and the limiting boss 305, and the side skirt trim of the automobile is auxiliary clamped and positioned by the cooperation of the anti-slip clamping plate 201 and a pair of auxiliary supporting plates 301, thereby ensuring the stability of the automobile side skirt trim inspection fixture.
