Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0038] For examples, please refer to Figures 1-5 A portable testing device for a commercial vehicle tilting bracket includes a base plate 1. A left positioning block 2 and a right positioning block 3 are respectively disposed in the middle of the base plate 1, and the left positioning block 2 and the right positioning block 3 are arranged collinearly. The left positioning block 2 and the right positioning block 3 are provided with a first testing component for detecting the tilting bracket connection mounting holes and outward openings. A first positioning block 4 is disposed on the base plate 1 between the left positioning block 2 and the right positioning block 3.

The first positioning block 4 has a "T"-shaped cross-section. A second positioning block is disposed on the base plate 1 on the side of the first positioning block 4. 5. A clamping device 6 is detachably connected to the second positioning block 5. The flip bracket is placed on the first positioning block 4. The left positioning block 2 and the right positioning block 3 are located on both sides of the flip bracket. The clamping device 6 on the second positioning block 5 is used to fix the flip bracket. Then, the first detection component and the second detection component respectively detect each hole and its outer opening of the flip bracket. If all of them meet the requirements, the product is qualified. If any one does not meet the requirements, it is returned to the previous process for processing, thereby preventing unqualified products from flowing into the next process, ensuring the quality stability of the flip bracket after it is installed on the vehicle, thereby effectively shortening the detection time and improving the detection efficiency.

[0039] Furthermore, the side of the second positioning block 5 that contacts the clamping device 6 is inclined. The second positioning block 5 is provided with a threaded hole, and the bottom surface of the clamping device 6 is provided with a mounting hole. The mounting holes of the clamping device 6 correspond one-to-one with the threaded holes in the fourth positioning block and are threadedly connected by bolts 7. There are four mounting holes on the clamping device 6. When the flipping bracket is placed on the upper surface of the first positioning block 4, the clamping device 6 is rotated to press the pressure rod of the clamping device 6 against the upper end surface of the first positioning block 4. At this time, it is pressed against the upper end surface of the front mounting plane of the flipping bracket. The bottom of the pressure rod of the clamping device 6 is located in the middle of the transverse part 42 of the first positioning block 4, that is, the clamping position of the clamping device 6 is located in the middle of the front mounting plane, which makes the clamping more stable and prevents the flipping bracket from shifting during the testing process.

[0040] Furthermore, the first positioning block 4 includes a longitudinal portion 41 and a transverse portion 42. The two sides of the longitudinal portion 41 are in contact with the left positioning block 2 and the right positioning block 3, respectively. The second positioning block 5 is located on one side of the transverse portion 42. The upper end of the transverse portion 42 is inclined away from the end of the longitudinal portion 41. The cross-section of the first positioning block 4 is "T" shaped and the upper end of the transverse portion 42 is inclined, so that the first positioning block 4 matches the shape of the flipping bracket. At the same time, the first positioning block 4 is completely matched with the contour of the vehicle body longitudinal beam and the front bulkhead. The size and shape of the first positioning block 4 are made as small as possible, which not only enables complete simulation of vehicle loading, but also reduces the weight of the device and facilitates subsequent handling and carrying.

[0041] Furthermore, the second detection component includes mounting holes 2 8 recessed on opposite sides of the longitudinal portion 41 and opposite sides of the transverse portion 42, respectively. T-shaped bushings 9 are interference-fitted into the mounting holes 2 8, and positioning pins 10 can be inserted into the T-shaped bushings 9. The positioning pins 10 are perpendicular to the upper surfaces of the longitudinal portion 41 and the transverse portion 42, respectively. A cylindrical positioning pin 11 is provided at the middle of the upper end of the longitudinal portion 41. Two adjacent first pins 12 are provided at the middle of the bottom surface of the first positioning block 4. A first countersunk hole is provided on the first positioning block 4 with the two first pins 12 on opposite sides, and a first countersunk bolt 13 is threaded into the first countersunk hole. During detection, the two front mounting holes of the flip bracket are aligned with the two mounting holes 2 8 in the transverse portion 42, the two bottom longitudinal beam mounting holes are aligned with the two mounting holes 2 8 in the longitudinal portion 41, and the bottom longitudinal beam positioning pin mounting holes are aligned with the cylindrical positioning pins 11. The front mounting plane of the flip bracket is placed on the surface of the transverse portion 42, and the flip bracket is... The mounting plane of the bottom longitudinal beam of the bracket is placed on the longitudinal part 41, so that the positioning pin 10 passes through the front mounting hole and the bottom longitudinal beam mounting hole without interference and is inserted into the T-shaped bushing 9, and the outer surface of the cylindrical positioning pin 11 passes through the bottom longitudinal beam positioning pin mounting hole without interference. Then, the front mounting plane, front mounting hole, bottom longitudinal beam mounting plane, bottom longitudinal beam mounting hole, and bottom longitudinal beam positioning pin mounting hole of the flip bracket are all qualified. At the same time, the T-shaped bushing 9 is interference-fitted with the mounting hole 8 to improve the stability of the T-shaped bushing 9. The upper end face of the T-shaped bushing 9 contacts the mounting surface of the flip bracket to avoid inaccurate positioning caused by uneven contact. The positioning pin 10 is inserted into the T-shaped bushing 9 to connect and fix the flip bracket to the first positioning block 4, thereby improving the stability of the flip bracket during testing. In addition, the first pin 12 and the first countersunk bolt 13 are used to connect the first positioning block 4 to the base plate 1. The detachable connection method facilitates the replacement of the first positioning block 4.

[0042] Furthermore, the bottom of the pressure rod in the clamping device 6 on the second positioning block 5 can abut against the middle of the upper end face of the transverse part 42. The pressure rod in the clamping device 6 is perpendicular to the upper end face of the transverse part 42. The clamping device 6 is inclined so that its pressure rod is perpendicular to the front mounting plane of the flip bracket, ensuring that the clamping force is perpendicular to the front mounting plane and ensuring the fixed stability of the flip bracket.

[0043] Furthermore, the first detection component includes a mounting hole 3 14 in the left positioning block 2, in which a detection sleeve 15 is fitted; a mounting hole 4 16 in the right positioning block 3, in which a detection sleeve 2 17 is fitted; bolt holes are respectively provided on the left positioning block 2 and the right positioning block 3, and fixing bolts 18 are threaded into the bolt holes; the left positioning block 2 and the right positioning block 3 are fixedly connected to the detection sleeve 15 and the detection sleeve 2 17 respectively by the fixing bolts 18; and the mounting hole 3 14 and the mounting hole 16 are respectively fixedly connected to the detection sleeve 15 and the detection sleeve 2 17 by the fixing bolts 18. The centers of holes 16 are collinear. A detection pin 19 is inserted between detection sleeve 15 and detection sleeve 2. After the front mounting plane and the bottom longitudinal beam mounting surface of the flip bracket are placed on the first positioning block 4 and the clamping device 6 clamps the front mounting plane of the flip bracket, the detection pin 19 is inserted into the inner hole of detection sleeve 2 17, the connecting mounting hole of the flip bracket and the inner hole of detection sleeve 15 in sequence. During this process, if the detection pin 19 passes through the two connecting mounting holes without interference, the connecting mounting hole is qualified.

[0044] Furthermore, it also includes a horizontally set opening detection feeler gauge 20. There are two opening detection feeler gauges 20, which are respectively set on the opposite side of the left positioning block 2 and the right positioning block 3. If the go gauge of the opening detection feeler gauge 20 can pass through the gap between the flip bracket and the left and right positioning blocks 3, and the no-go gauge of the opening detection feeler gauge 20 cannot pass through the gap between the flip bracket and the left and right positioning blocks 3, then the outer opening detection of the flip bracket is qualified.

[0045] It is important to understand that the open-cut feeler gauge 20 has a stepped surface. The smaller stepped surface is the go gauge surface, and the larger stepped surface is the stop gauge surface. The difference in height between the two stepped surfaces is 0.5mm. The combination can inspect a product tolerance of 1mm (the difference in height of the stepped surfaces can be adjusted according to the inspection requirements to inspect different tolerances).

[0046] Furthermore, two adjacent second pins 21 are provided in the middle of the bottom surface of both the left positioning block 2 and the right positioning block 3. Second countersunk holes are provided on both sides of the left positioning block 2 and the right positioning block 3. Second countersunk bolts 22 are threaded into the second countersunk holes. The left positioning block 2 and the right positioning block 3 are fixed to the base plate 1 by the second pins 21 and the second countersunk bolts 22. This is a detachable connection method, which is convenient for disassembly and replacement.

[0047] Furthermore, handles 23 are symmetrically arranged on both sides of the base plate 1. The handles 23 are "C" shaped and are fixedly connected to the base plate 1 by fixing bolts 18. The design of the handles 23 facilitates the overall handling of the device.

[0048] Furthermore, the second positioning block 5 is fixedly connected to the base plate 1 by connecting bolts. The second positioning block 5 and the base plate 1 are detachably connected, making disassembly convenient and easy to replace.

[0049] Working principle of this utility model:

[0050] During testing, align the two front mounting holes of the flip bracket with the two mounting holes 8 in the transverse part 42, align the two bottom longitudinal beam mounting holes with the two mounting holes 8 in the longitudinal part 41, and align the bottom longitudinal beam positioning pin mounting hole with the cylindrical positioning pin 11. Place the front mounting plane of the flip bracket on the transverse part 42 and the bottom longitudinal beam mounting plane of the flip bracket on the longitudinal part 41. Insert the positioning pin 10 through the front mounting holes and the bottom longitudinal beam mounting holes into the holes of the T-shaped bushing 9. Then, use the pressure rod in the clamp 6 to contact and fix it with the front mounting plane. Insert the detection pin 19 into the inner hole of the detection sleeve 17, the connecting mounting hole of the flip bracket, and the inner hole on the side of the detection sleeve 15. Then, place the gap detection feeler gauge 20 in the gap between the flip bracket and the left and right positioning blocks 3.

[0051] If the positioning pin 10 passes through the front mounting hole and the bottom longitudinal beam mounting hole without interference and is inserted into the T-shaped bushing 9, the outer surface of the cylindrical positioning pin 11 passes through the bottom longitudinal beam positioning pin mounting hole without interference, the inspection pin 19 passes through the two connecting mounting holes without interference, and the go gauge of the open-end inspection feeler gauge 20 can pass through the gap between the flip bracket and the left and right positioning blocks 3, and the no-go gauge of the open-end inspection feeler gauge 20 cannot pass through the gap between the flip bracket and the left and right positioning blocks 3, then the product is qualified. If any of them do not meet the requirements, they are returned to the previous process for processing, thereby preventing unqualified products from flowing into the next process and ensuring the quality stability of the flip bracket after it is installed on the vehicle.
