Description

Technical Field

[0001] This utility model relates to the field of testing tooling technology, and in particular to a rapid testing tooling for automotive roof parts. Background Technology

[0002] The car roof is a cover on the top of the car body and is an important component of the car body. It has protective, structural and control functions. The inspection of car roof components refers to the process of quality and performance testing of the car roof and its related components to ensure that they meet design requirements and safety standards. The main components of the car roof include the roof body, roof reinforcement, and roof accessories.

[0003] During the process of measuring the width of the car roof, the width of the roof may vary at any point because the two sides of the roof are symmetrical but have a certain curvature, making it difficult for workers to accurately measure the width of the roof at every point.

[0004] Therefore, considering that the symmetrical and curved sides of the car roof body cause the width from one end of the roof to the other to be a non-fixed value, and the curvature makes the width gradually change along the length of the roof body, making it difficult for workers to accurately measure the width of every part of the roof body, a rapid inspection fixture for car roof parts can be designed. This fixture solves the above problem by allowing the distance between the infrared range sensor and the baffle to change in real time according to the width of the object being measured during the measurement process. Utility Model Content

[0005] To overcome the difficulty in accurately measuring the width of a car roof during the measurement process, which is complicated by the fact that the symmetrical and curved sides of the roof result in a non-fixed width from one end to the other, and the curvature causes the width to gradually change along the length of the roof, making it difficult for workers to accurately measure the width of every part of the roof.

[0006] The technical solution of this utility model is as follows: a rapid inspection tooling for automotive roof parts, including a bracket; and a roller frame. Both sides of the inner side of the bracket are provided with lower forward and reverse thread bidirectional slide rails. A sliding parting vise is slidably connected to the front end of each of the lower forward and reverse thread bidirectional slide rails. A fixed parting vise is fixedly connected to the middle of the sliding parting vise. A through-beam photoelectric switch sensor is fixedly connected to the upper end of each sliding parting vise. A roller frame is provided at the upper end of the lower forward and reverse thread bidirectional slide rails. A rotating roller is rotatably connected inside the roller frame. Two first spring guide rods are fixedly connected to the back of the roller frame. A slide frame is slidably connected to one side of each first spring guide rod. A second spring guide rod is slidably connected to the slide frame. A tactile switch is installed on one side of each second spring guide rod. The roller frame is configured as two roller frames, left and right. An infrared ranging sensor is installed at the upper end of one roller frame, and a baffle is installed at the upper end of the other roller frame.

[0007] Preferably, the two sliding split vices installed at the front and rear ends of the device are moved closer to or farther away from each other by the two lower bidirectional sliding rails on both sides until the distance between the front and rear two pairs of photoelectric sensors on the same side is equal to the standard length of the object to be measured, and the photoelectric sensors on both sides are always aligned with each other. When the object to be measured placed on the upper end of the conveyor is displaced forward to block the front and rear two pairs of photoelectric sensors at the same time, the conveyor stops, and then the lower bidirectional sliding rails are pushed by the electric push rod to clamp and position the object to be measured in the middle of the device by the sliding split vices and the fixed split vices. Then, the two carriages and roller frames on both sides are moved closer to each other by the upper bidirectional sliding rails, and when the rollers contact the object to be measured, the roller frames slide on the carriages by pressing the first spring guide rods until the roller frames press the microswitches, and then the upper bidirectional sliding rails stop rotating. Then, the infrared distance sensor is turned on to irradiate the baffle to obtain the width data of the current position, and the upper bidirectional sliding rails and the roller frames are displaced forward and backward by the one-way screw rail. When the object to be measured becomes wider, the roller frames continue to press the first spring guide rods and the second spring guide rods to slide on the carriages. When the object to be measured becomes narrower, the first spring guide rods reset the roller frames, causing the roller frames to separate from the microswitches, and then the upper bidirectional sliding rails continue to tighten the roller frames until the roller frames press the microswitches again. In this measurement process, the distance between the infrared distance sensor and the baffle changes in real time according to the width of the object to be measured, and the infrared distance sensor transmits the measurement data to the computer or other data terminal through the data line.

[0008] Preferably, the second spring guide rod is arranged between the upper and lower first spring guide rods, and a distance equal to one-fifth of the total length of the microswitch is arranged between the microswitch and the roller frame.

[0009] Preferably, one side of the carriage is provided with a synchronization plate, and the synchronization plate is fixedly connected with the upper and lower first spring guide rods on the same side. The back surface of the lower bidirectional sliding rail is provided with two electric push rods, and the electric push rods are fixedly connected with the bracket.

[0010] Preferably, the upper ends of the two carriages are slidably connected with the upper bidirectional sliding rail, and the microswitch is electrically connected with the upper bidirectional sliding rail.

[0011] Preferably, the two sides of the upper bidirectional sliding rail are provided with the first rotary hydraulic cylinder, and the back surfaces of the two first rotary hydraulic cylinders are provided with a mounting bracket.

[0012] Preferably, the upper end of the mounting bracket is slidably connected with the one-way screw rail, and the upper end of the one-way screw rail is rotatably connected with the second rotary hydraulic cylinder.

[0013] Preferably, the second rotary hydraulic cylinder is fixedly connected to the upper end face of the bracket, the one-way screw slide rail is rotatably connected to the bracket, a transmitter is installed at the lower end of the bracket, and a through-beam photoelectric switch sensor is electrically connected to the transmitter.

[0014] The beneficial effects of this utility model are:

[0015] By setting up a first spring guide rod, a second spring guide rod, a tactile switch, and an infrared ranging sensor, the object to be tested is clamped and positioned in the center of the device via an electric push rod, a sliding parting vise, and a fixed parting vise. Then, the two side carriages and roller frames are brought closer together. After the rollers contact the object to be tested, the roller frames press the first spring guide rod, causing it to slide on the carriage until the roller frames press against the tactile switch, at which point the upper forward and reverse thread bidirectional slide rail stops rotating. Then, the infrared ranging sensor is activated to illuminate the baffle and obtain the width data of the current position. Simultaneously, the upper forward and reverse thread bidirectional slide rail is activated via a unidirectional lead screw. The slide rail and roller frame move back and forth. When the object to be measured changes from narrow to wide, the roller frame continues to press the first spring guide rod and simultaneously presses the second spring guide rod to slide on the slide. When the object to be measured changes from wide to narrow, the first spring guide rod causes the roller frame to reset, causing the roller frame to separate from the tactile switch. Then, the upper positive and negative toothed bidirectional slide rail continues to tighten the roller frame until the roller frame presses the tactile switch again. Thus, during this measurement process, the distance between the infrared ranging sensor and the baffle changes in real time according to the width of the object to be measured, so as to quickly and accurately measure the width of each part of the top cover body in a simple and convenient way.

[0023] Please refer to Figures 1-3In the embodiment, the second spring guide rod 10 is arranged between the upper and lower first spring guide rods 8, the distance between the light touch switch 11 and the roller frame 6 is equal to one fifth of the total length of the light touch switch 11, one side of the sliding frame 9 is provided with a synchronization plate 14, the synchronization plate 14 is fixedly connected with the upper and lower first spring guide rods 8 on the same side, two electric push rods 15 are mounted on the back surface of the lower positive and negative tooth bidirectional sliding rail 2, and the electric push rod 15 is fixedly connected with the support 1, the synchronization plate 14 is used to increase the uniformity of the force of the upper and lower first spring guide rods 8 when the roller frame 6 is unevenly stressed, so as to reduce the friction between the first spring guide rod 8 and the sliding frame 9, the upper ends of the two sliding frames 9 are commonly connected with the upper positive and negative tooth bidirectional sliding rail 16, and the light touch switch 11 is electrically connected with the upper positive and negative tooth bidirectional sliding rail 16.

[0024] Please refer to Figure 1 and Figure 4 In the embodiment, the first rotary hydraulic cylinder 17 is mounted on both sides of the upper positive and negative tooth bidirectional sliding rail 16, the back surfaces of the two first rotary hydraulic cylinders 17 are commonly mounted with a mounting frame 18, the first rotary hydraulic cylinder 17 is used to rotate and lift the upper positive and negative tooth bidirectional sliding rail 16 by 90 degrees, so that the sliding frame 9 changes from the state of being perpendicular to the conveyor 21 to being parallel to the conveyor 21, the upper end of the mounting frame 18 is slidably connected with the one-way screw rod sliding rail 19, the upper end of the one-way screw rod sliding rail 19 is rotatably connected with the second rotary hydraulic cylinder 20, the second rotary hydraulic cylinder 20 is used to rotate the one-way screw rod sliding rail 19, the mounting frame 18 and the upper positive and negative tooth bidirectional sliding rail 16 by 90 degrees, the second rotary hydraulic cylinder 20 is fixedly connected with the upper end surface of the support 1, the one-way screw rod sliding rail 19 is rotatably connected with the support 1, and the conveyor 21 is mounted on the lower end of the support 1. The light barrier photoelectric switch sensor 5 is electrically connected with the conveyor 21.

[0025] In use, first, through the two lower bidirectional slide rails 2 on both sides, the two sliding split vice 3 installed at the front and rear ends are moved closer to each other or farther away from each other until the distance between the front and rear two pairs of infrared photoelectric switch sensors 5 on the same side is equal to the standard length of the object to be measured, and the two pairs of infrared photoelectric switch sensors 5 on both sides are always aligned with each other. When the object to be measured placed on the upper end of the conveyor 21 is displaced forward to simultaneously block the front and rear two pairs of infrared photoelectric switch sensors 5, the conveyor 21 stops, and then the lower bidirectional slide rail 2 is pushed by the electric push rod 15 to clamp and position the object to be measured in the middle of the device by using the sliding split vice 3 and the fixed split vice 4. Next, the two carriages 9 and roller frames 6 on both sides are moved closer to each other by the upper bidirectional slide rail 16. When the rollers 7 contact the object to be measured, the roller frame 6 pushes the first spring guide rod 8 to slide on the carriage 9 until the roller frame 6 is pressed against the micro switch 11, and then the upper bidirectional slide rail 16 stops rotating. Then the infrared distance sensor 12 is turned on to irradiate the baffle 13 to obtain the width data of the current position. At the same time, the upper bidirectional slide rail 16 and the roller frame 6 are displaced forward and backward by the one-way screw rail 19. When the object to be measured becomes wider, the roller frame 6 continues to press the first spring guide rod 8 and the second spring guide rod 10 to slide on the carriage 9. When the object to be measured becomes narrower, the first spring guide rod 8 resets the roller frame 6, causing the roller frame 6 to separate from the micro switch 11. Thus, the upper bidirectional slide rail 16 continues to tighten the roller frame 6 until the roller frame 6 presses the micro switch 11 again. During this measurement process, the distance between the infrared distance sensor 12 and the baffle 13 changes in real time according to the width of the object to be measured, and the infrared distance sensor 12 transmits the measurement data to the computer or other data terminal through the data line.

[0026] If the front and back of the object to be measured are also symmetrical, and the length of the object to be measured is to be measured, first, the upper bidirectional slide rail 16 is rotated and lifted by 90 degrees by the first rotary hydraulic cylinder 17, so that the carriage 9 changes from a state perpendicular to the conveyor 21 to a state parallel to the conveyor 21. Then, the one-way screw rail 19, the mounting frame 18, and the upper bidirectional slide rail 16 are rotated by 90 degrees by the second rotary hydraulic cylinder 20. Next, the upper bidirectional slide rail 16 and the carriage 9 that have been rotated and lifted by 90 degrees are lowered. Then the above steps for measuring the width of the object to be measured can be repeated to measure the length of the object to be measured, thereby improving the functionality and convenience of the device.

[0027] Through the above steps, by setting the first spring guide rod 8, the second spring guide rod 10, the light touch switch 11 and the infrared distance sensor 12, the measured object is clamped and positioned in the middle of the device through the electric push rod 15, the sliding dividing vice 3 and the fixed dividing vice 4, then the two carriages 9 and the roller frame 6 on both sides are close to each other, after the rotating roller 7 contacts the measured object, the roller frame 6 extrudes the first spring guide rod 8 to slide on the carriage 9 until the roller frame 6 presses the light touch switch 11 and the upper positive and negative tooth bidirectional slide rail 16 stops rotating, then the infrared distance sensor 12 is turned on to irradiate the baffle 13 to obtain the width data of the current position, at the same time, the upper positive and negative tooth bidirectional slide rail 16 and the roller frame 6 are displaced forward and backward through the one-way screw slide rail 19, when the measured object becomes wide, the roller frame 6 continues to extrude the first spring guide rod 8 and at the same time extrudes the second spring guide rod 10 to slide on the carriage 9, when the measured object becomes narrow, the first spring guide rod 8 resets the roller frame 6 to cause the roller frame 6 to separate from the light touch switch 11, so the upper positive and negative tooth bidirectional slide rail 16 continues to tighten the roller frame 6 until the roller frame 6 presses the light touch switch 11 again, so that the distance between the infrared distance sensor 12 and the baffle 13 can change in real time according to the width of the measured object during the measurement process, so that the width of each part of the top cover body can be measured quickly and accurately in a simple and convenient way.
