Description

Technical Field

[0001] This utility model relates to a detection device, specifically a detection device for preventing leakage of front beam metal inserts, belonging to the field of automotive parts manufacturing technology. Background Technology

[0002] Automotive front beam metal inserts are embedded metal components used in vehicle structures (such as front bumper beams and sill beams). They are typically fixed in composite or lightweight materials through embedding or molding processes to enhance local strength, connection function, or collision energy absorption performance. During production, front beam metal inserts may be missing. Currently, detecting missing inserts relies solely on manual inspection. However, manual inspection, especially after prolonged work and periods of inattention, can easily lead to misdetection, resulting in defective products and increased after-sales issues.

The shape of the fixed plate matches the shape of the front beam and the fixed plate is fixed to one side of the base plate. The movable plate is slidably disposed on the base plate and is disposed opposite to the fixed plate. The movable plate is driven by the movable plate drive mechanism to move horizontally. The fixed plate is provided with a number of detection heads equal to the number of front beam metal inserts. Each detection head is provided with two detection terminals, and the two detection terminals form a circuit with a resistance meter.

[0018] like Figure 1 As shown, this utility model discloses a front beam metal insert leak-proof detection device, comprising a base plate 1, a fixed plate 2, a movable plate 3, and a movable plate driving mechanism. The shape of the fixed plate 2 matches the shape of the front beam 4 and the fixed plate 2 is fixed to one side of the base plate 1. The movable plate 3 is slidably disposed on the base plate 1 and is disposed opposite to the fixed plate 2. The movable plate 3 is driven by the movable plate driving mechanism to move horizontally. Figure 2 As shown, the fixed plate 2 is provided with a number of detection heads 5 equal to the number of metal inserts in the front beam. Each detection head 5 is provided with two detection terminals, and the two detection terminals and the resistance meter form a circuit.

[0019] like Figure 1 As shown, a side plate 6 is provided on each side of the fixed plate 2. The two side plates 6 are arranged in parallel, and the inner side of the side plate 6 facing the front beam has a chamfer. The two side plates 6 and the fixed plate 2 form a groove that matches the front beam 4. In use, the front beam 4 is installed in the groove formed by the two side plates 6 and the fixed plate 2, and then the front beam 4 is fixed by moving the movable plate 3.

[0020] Two rubber pads 7 are provided on the side of the movable plate 3 facing the front beam. The positions of the two rubber pads 7 correspond to the positions of the two mounting brackets of the front beam 4. The rubber pads 7 are detachably fixed to the rubber pad mounting base 8 by bolts, and the rubber pad mounting base 8 is fixed to the movable plate 3. The rubber pads 7 avoid direct contact between the movable plate 3 and the front beam 4, thus preventing damage to the surface of the front beam 4 during the inspection process.

[0021] like Figure 1As shown, the movable plate drive mechanism includes a screw 9, a nut 10, a first screw bracket 11, a second screw bracket 12, and a handle 13. The first screw bracket 11 and the second screw bracket 12 are fixed on the base 1 and are located on both sides of the movable plate 3, respectively. The two ends of the screw 9 are rotatably mounted on the first screw bracket 11 and the second screw bracket 12, respectively. The handle 13 is fixed to one end of the screw 9. The nut 10 is threaded onto the screw 9. The movable bracket 3 has a through hole that matches the nut 10, and the nut 10 is fixed in the through hole of the movable bracket 3. During operation, the screw 9 is rotated by the handle 13, which in turn drives the movable plate 3 to move back and forth on the upper side of the base plate 1 via the nut 10, thereby adjusting the distance between the fixed plate 2 and the movable plate 3, and completing the clamping and releasing operation of the front beam 4.

[0022] The base 1 is provided with two slide rails 14, which are perpendicular to the movable plate 3. The two ends of the movable plate 3 are slidably mounted on the two slide rails 14.

[0023] like Figure 3 As shown, the detection head 5 includes a housing 15, a first detection terminal 16, and a second detection terminal 17. The first detection terminal 16 has a first protruding ring 18 protruding from its outer side. The second detection terminal 17 has a second protruding ring 19 protruding from its outer side. A first blind hole 20 matching the first protruding ring 18 is opened on one side of the housing 15, and the end diameter of the first blind hole 20 is reduced to match the outer diameter of the first detection terminal 16. A second blind hole 21 matching the second protruding ring 19 is opened on one side of the housing 15. The end diameter of the second blind hole 21 is reduced to match the outer diameter of the second detection terminal 17. The first detection terminal 16 is slidably disposed within the first blind hole 20 via the first protruding ring 18, and the second detection terminal 17 is slidably disposed within the second blind hole 21 via the second protruding ring 19. A first spring 22 is sleeved on the outside of the first detection terminal 16, located between the first protruding ring 18 and the bottom of the first blind hole 20. A second spring 23 is sleeved on the outside of the second detection terminal 17, located between the second protruding ring 19 and the bottom of the second blind hole 21. The front beam 4 is placed on the side of the fixed plate 2, and the movable plate 3 clamps and fixes the front beam 4 close to the fixed plate 2, thereby making contact between the detection head 5 and the metal insert on the front beam 4. If a metal insert is present, a conductive circuit is formed between the first detection terminal 16 and the second detection terminal 17 of the detection head 5 through the metal insert, and the resistance meter detects a very small resistance; otherwise, the resistance meter detects a large resistance, thus completing the automatic detection of the metal insert. The first detection terminal 16 and the second detection terminal 17 adopt a blind hole and spring telescopic structure design to ensure good contact with the surface of the metal insert and to avoid damage to the detection head 5 during the clamping and fixing process of the movable plate 3.

[0024] An instrument mounting plate 24 is provided on the rear side of the base 1, and several resistance meters are mounted on the instrument mounting plate 24. The two detection terminals of the detection head 5 are positioned opposite to one of the resistance meters on the instrument mounting plate 24 and form a detection circuit.

[0025] This utility model discloses a front beam metal insert anti-leakage detection device. After the front beam is fixedly clamped between a fixed plate and a movable plate, a detection circuit is formed at the metal insert part through two detection terminals on the detection head.
