Description

Technical Field

[0001] This utility model relates to the field of aerospace mechanical manufacturing technology, and in particular to a thickness gauge bracket and a thickness gauge. Background Technology

[0002] Due to their advantages such as light weight, high specific strength and specific stiffness, and good designability, carbon fiber reinforced resin matrix composite parts are increasingly used in the aerospace field. Because the aerospace industry needs to consider the assembly performance of parts, aircraft payload capacity, and manufacturing and maintenance costs, it has high requirements for the dimensional accuracy of parts.

[0003] Because composite material fuselage stringers, bulkheads, and corner pieces are numerous, large in size, and complex in structure, thickness inspection of these parts is difficult and time-consuming. Therefore, it is particularly important to improve the efficiency and accuracy of thickness inspection of such composite material parts.

[0004] Magnetic thickness gauges are a common method for measuring the thickness of composite material parts. When using a magnetic thickness gauge, the measuring probe must be perpendicular to the surface being measured. Existing thickness gauges have a one-piece, non-adjustable stand. While convenient for measuring planar structures, magnetic thickness gauges provide accurate and stable data. However, when measuring the thickness of the R-zone (radial region) of a part, it is difficult to fix the measuring probe on a curved surface and ensure it is perpendicular to the surface, leading to larger measurement errors and poor stability.

[0038] like Figures 1-5As shown, this embodiment provides a thickness gauge bracket, which includes a clamping assembly 6, a support member 1, and two bases 2. The clamping assembly 6 is used to connect the thickness gauge body 8. The support member 1 is connected to the clamping assembly 6 and is used to support the clamping assembly 6. The support member 1 includes two spaced-apart support rods 11. The two bases 2 are rotatably connected to the first ends of the two support rods 11 and can be fixed at a preset angle so that the two bases 2 can fit against the workpiece 10 to be measured. By adjusting the angle of the two bases 2, the thickness gauge bracket can fix the bases 2 at a suitable angle according to the different curvatures of the R-zone of the workpiece 10 to be measured, so that the bases 2 can fit against the workpiece 10 to be measured, improving the stability of the measurement. By adjusting the angle of the bases 2, the thickness gauge body 8 is made perpendicular to the measuring surface of the workpiece 10 to be measured, so that the thickness gauge body 8 can accurately measure the surface of the workpiece 10 to be measured, improving the measurement accuracy. By adjusting the angle of the bases 2 according to the angle of the workpiece 10 to be measured, the bases 2 can fit against the workpiece 10 to be measured with any curvature, so that the thickness gauge bracket is not limited by the curvature of the workpiece 10 to be measured. Furthermore, by moving the base 2, the thickness gauge body 8 moves synchronously with the thickness gauge bracket, changing the measurement position of the thickness gauge body 8 and enabling continuous measurement of more than 10 points on the workpiece, thus improving measurement efficiency. Finally, the overall structure of the thickness gauge bracket is simple, making it easy to install and use.

[0039] Specifically, the base 2 is provided with a fitting part 21 and a connecting part 22. The fitting part 21 is a square plate-like structure. The connecting part 22 consists of two rectangular mounting plates, which are arranged parallel to each other and perpendicularly connected to one side of the fitting part 21. The other side of the fitting part 21 is used to fit the test piece 10. A rubber pad is provided on the side of the fitting part 21 facing the test piece 10. The rubber pad fits against the test piece 10, and the base 2 and the test piece 10 are in elastic contact through the rubber pad, ensuring a good fit between the base 2 and the test piece 10. This prevents the base 2 from being affected by the curing deformation and springback of the test piece 10, improving the stability and accuracy of the measurement, while also preventing the base 2 from scratching the test piece 10, thus protecting the test piece 10. The clamping assembly 6, the support 1, and the base 2 are all made of non-magnetic aluminum alloy.

[0040] Preferably, the clamping component 6 is a clamp, and the side wall of the clamp is connected to the support 1, which facilitates the installation and disassembly of the thickness gauge body 8.

[0041] Specifically, the clamping assembly 6 includes a first clamping member 61 and a second clamping member 62 connected to each other. Both the first clamping member 61 and the second clamping member 62 are semi-circular, forming a mounting hole 63, through which the thickness gauge body 8 passes. Both ends of the first clamping member 61 are provided with third through holes, and both ends of the second clamping member 62 are provided with first threaded holes. Two first screws 9 are respectively inserted through the third through holes and threaded into the first threaded holes to press the thickness gauge body 8 against the inner wall of the mounting hole 63. By tightening the first screws 9, the size of the mounting hole 63 can be adjusted to fix thickness gauge bodies 8 of different sizes. Rubber strips are provided on the inner walls of the first clamping member 61 and the second clamping member 62, which abut against the thickness gauge body 8 to improve the connection strength between the thickness gauge body 8 and the clamping assembly 6. The rubber strip can be connected to the inner wall of the first clamping member 61 and the second clamping member 62 by means of bonding or snapping, and this embodiment does not limit this.

[0042] Preferably, such as Figures 1-3 As shown, the support member 1 also includes a crossbeam 12. The second ends of the two support rods 11 are respectively connected to the two ends of the crossbeam 12. The support member 1 is U-shaped to connect the two support rods 11. The crossbeam 12 is connected to the clamping assembly 6 to fix the support member 1 to the clamping assembly 6. The two bases 2 are symmetrically arranged relative to the thickness gauge body 8. By fixing the two bases 2 at the same angle, the thickness gauge body 8 can be made perpendicular to the surface to be measured of the workpiece 10, which facilitates the conversion of the angles of the two bases 2.

[0043] Specifically, the two support rods 11 are perpendicular to the crossbeam 12. A second threaded hole 121 is provided in the middle of the crossbeam 12, and a fourth through hole is provided in the middle of the second clamping member 62. The second screw passes through the fourth through hole and is threaded to the second threaded hole 121.

[0044] Preferably, such as Figures 1-5 As shown, the thickness gauge bracket also includes two connectors 3, which correspond one-to-one with two support rods 11. One end of the connector 3 is connected to the first end of the support rod 11, and the other end extends outward. The base 2 is rotatably connected to the end of the connector 3 away from the support rod 11. By setting the connectors 3, interference between the base 2 and the support rod 11 or between the two bases 2 is avoided when adjusting the angle of the base 2, thereby increasing the range of angle adjustment of the base 2.

[0045] More preferably, the first ends of the two support rods 11 are inclined inwards, and the first ends of the two support rods 11 are symmetrically arranged relative to the thickness gauge body 8 and perpendicular to each other. The connecting piece 3 is perpendicular to the first ends of the support rods 11, which facilitates the conversion of the angle of the base 2 according to the angle of the part to be measured 10, so as to quickly and accurately adjust the angle of the base 2. Specifically, the first ends of the two support rods 11 are inclined inwards at 45° respectively.

[0046] Preferably, the connector 3 is a U-shaped plate. The connector 3 includes a first side plate 31, a second side plate 32, and a horizontal plate 33. The first side plate 31 and the second side plate 32 are respectively connected to the two ends of the horizontal plate 33. The horizontal plate 33 is connected to the first end of the support rod 11. The base 2 is rotatably connected between the first side plate 31 and the second side plate 32. Setting the connector 3 in a U-shape facilitates the connection of the connector 3 with the support rod 11 and the base 2, thereby improving the connection strength between the connector 3 and the support rod 11 and the base 2.

[0047] Preferably, the first end of the support rod 11 is provided with a positioning groove 111, and the horizontal plate 33 is embedded in the positioning groove 111 to improve the installation accuracy of the connector 3 and ensure that the two connectors 3 are symmetrical about the thickness gauge body 8.

[0048] Specifically, a U-shaped plate is sleeved on the first end of the support rod 11, a fifth through hole is provided in the middle of the horizontal plate 33, a third threaded hole is provided in the positioning groove 111, and a third screw passes through the fifth through hole and is threaded into the third threaded hole to fix the connector 3 to the support rod 11.

[0049] More preferably, the thickness gauge bracket also includes an adjusting bolt 7 and an adjusting nut. A first through hole is provided on the first side plate 31, a second through hole is provided on the second side plate 32, and a third through hole is provided on the base 2. The adjusting bolt 7 passes through the first through hole, the third through hole, and the second through hole in sequence and is threaded to the adjusting nut. Loosening the adjusting nut and rotating the base 2 to a suitable angle, then tightening the adjusting nut to fix the base 2, facilitates adjustment of the base 2's angle.

[0050] Specifically, the first through hole is located at the end of the first side plate 31 away from the horizontal plate 33, and the second through hole is located at the end of the second side plate 32 away from the horizontal plate 33. The end of the connecting part 22 away from the fitting part 21 is located between the first side plate 31 and the second side plate 32, and the third through hole is located on the connecting part 22.

[0051] Preferably, the thickness gauge bracket also includes two dials 4 and two indicator rods 5. The two dials 4, two indicator rods 5, two support rods 11 and two bases 2 correspond one-to-one. The dials 4 are connected to the support rods 11, and the indicator rods 5 are connected to the bases 2. The indicator rods 5 are used to indicate the scale of the dials 4 to obtain the angle of the base 2 relative to the support rods 11, so as to facilitate the adjustment of the base 2 to a suitable angle and improve the adjustment efficiency.

[0052] Specifically, a first slot is provided at the end of the first side plate 31 away from the horizontal plate 33, and a first engaging part is provided on the dial 4. The first engaging part engages with the first slot to fix the dial 4 to the connecting member 3, so that the dial 4 is connected to the support rod 11 through the connecting member 3. A second slot is provided at the end of the connecting part 22 away from the fitting part 21, and a second engaging part is provided on the indicator rod 5. The second engaging part engages with the second slot to fix the indicator rod 5 to the base 2, so that it rotates synchronously with the base 2, thereby causing the indicator rod 5 to rotate coaxially with the dial 4. The dial 4 has a flat-angled fan-shaped structure, and the arc edge of the dial 4 is engraved with lines at different angles, with an angle range of 0-180°. The 0 mark on the dial 4 is parallel to the extension direction of the first side plate 31, so that the angle reading a on the dial 4 and the angle b of the surface of the workpiece 10 to be measured satisfy the relationship 2a=90°+b. Based on the angle of the workpiece 10 to be measured, the required angle of the base 2 can be obtained quickly, thereby improving the adjustment efficiency of the base 2.

[0053] like Figure 1 and Figure 2 As shown, this embodiment also provides a thickness gauge, which includes a thickness gauge body 8 and the aforementioned thickness gauge bracket. The thickness gauge body 8 is connected to the clamping assembly 6. Specifically, the thickness gauge body 8 passes through the mounting hole 63. By rotating the first screw 9, the size of the mounting hole 63 is adjusted, and the thickness gauge body 8 is pressed against the inner wall of the mounting hole 63 to fix the thickness gauge body 8.

[0054] like Figures 1-5 As shown, the thickness gauge is used in this embodiment as follows:

[0055] Step 1: Place the part to be tested 10 on the special bracket and place it in the magnetic thickness measurement area. Check and confirm that there is no magnetic interference near the part to be tested 10.

[0056] Step 2: Select the appropriate thickness gauge body 8 according to the inspection requirements, connect it to the digital display device and calibrate it;

[0057] Step 3: Based on the angle of the R-zone curved surface structure of the test piece 10, calculate the required adjustment angle of the base 2, align the indicator rod 5 with the required scale line on the scale 4, and after confirming that the reading is correct, tighten the adjusting bolt 7 to fix the base 2.

[0058] Step 4: Loosen the first screw 9, install the thickness gauge body 8 in the mounting hole 63, and adjust the embedding height of the thickness gauge body 8 to ensure that the probe of the thickness gauge body 8 is in contact with the measuring surface of the workpiece 10 to be measured, and finally tighten the first screw 9.

[0059] Step 5: Hold the assembled thickness gauge and place it on the surface of the part to be measured 10, so that the rubber pad of the base 2 contacts the surface of the part to be measured 10, and check whether the rubber pad of the base 2 is in good contact with the surface of the part to be measured 10.

[0060] Step 6: Perform magnetic thickness measurement at the corresponding position point in the R area of ​​the test piece 10. The position of the moving base 2 can achieve continuous point measurement.
