[0002] With the continuous development and progress of science and technology, new materials are constantly emerging, and many new materials are widely used in rail transit vehicles. Among them, fiberglass materials are used more and more widely in current rail transit vehicles. For example, the driver's cab hood, passenger compartment seats, side wall panels, air conditioning ducts and other structures are all made of fiberglass materials. These were originally assembled by various fiberglass parts through stud holes, so the assembly accuracy of the stud holes is very important.

[0030] The embodiment of the utility model provides a tool for inspecting the same position of stud holes for installing fiberglass reinforced plastic parts of railway trains.

[0031] See also Figure 1 and Figure 2 , comprising an operating table 1, a support frame 2 is fixedly connected to the upper surface of the operating table 1, a centering mechanism 4 for centering is provided between the operating table 1 and the support frame 2, two symmetrical inspection mechanisms 5 are provided on the upper surface of the operating table 1, and a workpiece 6 is provided between the two inspection mechanisms 5;

[0032] The centering mechanism 4 includes a disc 401 and a cylinder 402. The disc 401 is provided with four circumferentially arranged sliding grooves 403 inside. A group of slides 1 404 and a group of slides 2 405 are slidably connected inside the four sliding grooves 403. One end of the cylinder 402 is fixedly connected to the upper surface of slide 1 404 through a bracket, and the other end of the cylinder 402 is fixedly connected to the upper surface of another slide 1 404 through a bracket. A fixed column 406 is fixedly connected to the center of the upper surface of the disc 401. The outer surface of the fixed column 406 is rotatably connected to a turntable 407. A rotating rod 1 408 is hinged between the turntable 407 and the two slides 1 404. When the cylinder 402 is started, the telescopic end of the cylinder 402 can drive the slide 1 404 fixedly connected to the telescopic end through the bracket to slide along the sliding groove 403. When the slide 1 404 slides outward along the sliding groove 403, it can drive the rotating rod 1 408 between the slide 1 404 and the turntable 407. 8 expands outward, and this rotating rod 1 408 can drive the turntable 407 to rotate clockwise when it expands outward, so that the turntable 407 can drive another rotating rod 1 408 to expand outward, and at the same time drive another slide 1 404 to slide outward, and a rotating rod 2 409 is hinged between the turntable 407 and the two slides 2 405, and the bottom surface of each slide 1 404 and slide 2 405 is fixedly connected with a clamping plate 410; since the two rotating rods 1 408 and the two rotating rods 2 409 are consistent in shape and length, when the two slides 1 404 move closer to or away from each other, they can simultaneously drive the two slides 2 405 to move closer to or away from each other, and then the four clamping plates 410 can push the workpiece 6 and the inspection plate 7 to the center and clamp them, so that the workpiece 6 and the inspection plate 7 remain on the same axis, which can improve the co-positioning accuracy of the stud and the stud hole, reduce the position deviation between the stud and the stud hole, and solve the centering problem of parts during assembly.

[0033] Four circumferentially arranged grooves 3 are formed inside the operating table 1 , and the bottom end of each clamping plate 410 is slidably connected to each groove 3 .

[0034] The bottom surface of the disc 401 is fixedly connected to the upper surface of the support frame 2 .

[0035] Please refer to Figure 3 and Figure 4 The inspection mechanism 5 includes a motor 501 and a fixed plate 502. The output end of the motor 501 is fixedly connected to a screw rod 503. The outer surface of the screw rod 503 is threadedly connected to a movable plate 504. The end of the movable plate 504 close to the clamping plate 410 is fixedly connected to a telescopic rod 505. The end of the telescopic rod 505 away from the movable plate 504 is provided with a clamping member 506.

[0036] Two auxiliary rods 507 are fixedly connected between the fixed plate 502 and the operating table 1. The outer surfaces of the auxiliary rods 507 are slidably connected to the movable plate 504, and the bottom end of the screw rod 503 is rotatably connected to the operating table 1. Activating the motor 501 in the inspection mechanism 5 causes the movable plate 504 to move downward along the auxiliary rods 507 and the screw rod 503, thereby enabling the telescopic rod 505 to move the clamping member 506 downward, and thus the workpiece 6 to move downward along this axis. This allows for the simultaneous inspection of stud holes without manual operation, improving inspection efficiency.

[0037] Please refer to Figure 4 The clamping member 506 includes a slider 5061 and a screw 5062. The outer surface of the slider 5061 is slidably connected to the splint 410 fixedly connected to the slide plate 2 405 through a convex strip. The outer surface of the screw 5062 is threadedly connected to the slider 5061. The bottom end of the screw 5062 is rotatably connected to the clamping block 5063, and the top end of the screw 5062 is fixedly connected to the twisting block 5064.

[0038] The outer surface of the slider 5061 is fixedly connected to a guide rod 5065, and the outer surface of the guide rod 5065 is slidably connected to the clamping block 5063. The outer surface of the slider 5061 is fixedly connected to the telescopic support plate 5066. Twisting the screw block 5064 can move the clamping block 5063 downward along the guide rod 5065, so that the clamping block 5063 and the telescopic support plate 5066 can clamp the workpiece 6.

[0039] Please refer to Figure 1 An inspection plate 7 is provided on the upper surface of the operating table 1. A plurality of stud holes of different diameters are provided inside the inspection plate 7. The spacing between the stud holes is not equal. Each stud hole can be movably installed with a movable column 701 adapted thereto.

[0040] When the utility model is in use, the workpiece 6 and the inspection plate 7 are placed between the four clamping plates 410, wherein the workpiece 6 is placed on the two telescopic support plates 5066, and the cylinder 402 is started, so that the telescopic end of the cylinder 402 can drive the slide 1 404 fixedly connected to the telescopic end through the bracket to slide along the slide groove 403. When the slide 1 404 slides outward along the slide groove 403, it can drive the rotating rod 1 408 between the slide 1 404 and the turntable 407 to expand outward. When the rotating rod 1 408 expands outward, it can drive the turntable 407 to rotate clockwise, so that the turntable 407 can drive another turntable Rod 1 408 expands outward and can drive another slide plate 1 404 to slide outward at the same time. Since the two rotating rods 1 408 and the two rotating rods 2 409 have the same shape and length, when the two slide plates 1 404 move closer to or away from each other, they can simultaneously drive the two slide plates 2 405 to move closer to or away from each other, thereby enabling the four clamping plates 410 to push the workpiece 6 and the inspection plate 7 to the center and clamp them, so that the workpiece 6 and the inspection plate 7 remain on the same axis, which can improve the co-positioning accuracy of the stud and the stud hole, reduce the position deviation between the stud and the stud hole, and solve the centering problem of parts during assembly.

[0041] Then, by twisting the screw block 5064, the clamping block 5063 can be moved downward along the guide rod 5065, so that the clamping block 5063 and the telescopic support plate 5066 can clamp the workpiece 6. Subsequently, the motors 501 in the two inspection mechanisms 5 are started at the same time, so that the movable plate 504 can be moved downward along the auxiliary rod 507 on the screw rod 503, so that the telescopic rod 505 can drive the clamping piece 506 to move downward, and then the workpiece 6 can be moved downward along this axis. The stud hole can be inspected in situ without manual operation, thereby improving the inspection work efficiency.
