Description

Technical Field

[0001] This utility model relates to the technical field of automotive dashboard testing equipment, and in particular to a testing fixture for automotive dashboard crossbeam parts. Background Technology

[0002] In the automotive parts manufacturing process, the dimensions of the first piece produced each time need to be inspected and confirmed to conform to the drawing specifications before mass production. Random checks are also conducted during production, and any deviations require timely adjustments to the processing equipment or tooling to ensure the produced parts are qualified. There are many inspection methods. Simple parts can be measured using vernier calipers, while complex and larger parts require large measuring equipment (coordinate measuring machines, scanners, etc.) or specialized inspection fixtures. While large measuring equipment offers high precision, it requires a dedicated space and is slow and inefficient, failing to meet daily inspection needs. Specialized inspection fixtures can be placed directly around the parts processing area; once the parts are finished, they can be quickly inspected and judged, offering speed and efficiency.

[0003] Application No. 2023100145921 discloses a tooling for quickly detecting the accuracy of the holes in the instrument panel crossbeam. The workpiece is clamped and fixed by clamps, and a flipping mechanism drives it to flip so that the detection pin on the connecting block corresponds to the detection hole for detection. A spring is set on the detection pin so that it can automatically reset to the non-tooling state after detection, which facilitates quick removal of the part and improves the convenience of use.

[0004] However, while existing technology allows the detection pins to quickly reset by setting springs, it cannot keep multiple detection pins inserted during use. It requires manual pressing of multiple detection pins simultaneously for detection, which cannot meet various detection needs. Furthermore, the detection pins are all locked in fixed positions on the connecting block and cannot be adjusted according to the position of the detection holes on the workpiece. This requires changing and adjusting multiple detection fixtures, which increases production costs. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a testing fixture for automotive dashboard crossbeam parts, so as to solve the problem that the testing position cannot be adjusted and that manual pressing is required to maintain the testing state during the testing process.

[0006] To achieve the above objectives, this utility model provides a testing fixture for automotive dashboard crossbeam parts, including a fixture base plate with testing simulation blocks at both ends. The two ends of the crossbeam are respectively placed on the testing simulation blocks at both ends. Clamping mechanisms are provided at both ends of the middle of the fixture base plate for clamping the crossbeam. A testing bracket is provided on one side of the middle of the fixture base plate, and a testing mechanism for testing the crossbeam is installed on the testing bracket. An adjustment mechanism for adjusting the position of the testing mechanism is provided on the testing bracket. A positioning bracket is provided on the other side of the middle of the fixture base plate, and a positioning mechanism for positioning the crossbeam is installed on the positioning bracket.

[0007] A further improvement is that the detection bracket includes a base fixedly installed on the base plate of the inspection fixture, a flip arm rotatably installed on the base, and a detection mechanism is located on one side of the flip arm.

[0008] A further improvement is that a locking bolt is threaded on one side of the tilting arm, and a threaded connection hole is correspondingly provided on one side of the base. The tilting arm is locked to the base by the locking bolt and the threaded connection hole.

[0009] A further improvement is that the detection mechanism includes an extension arm movably disposed on one side of the upper end of the flipping arm. The extension arm has a first mounting hole, and a detection pin is movably disposed through the first mounting hole. An operation button is installed on the top of the detection pin, and a detection spring is sleeved on the detection pin. The two ends of the detection spring abut against the extension arm and the operation button, respectively.

[0010] A further improvement is that a guide groove is provided on the inner wall of the first mounting hole, and a guide block is fixedly connected to the side wall of the detection pin. The guide block is slidably disposed in the guide groove. A limit groove is also provided on the inner wall of the first mounting hole. The limit groove is provided on one side of the guide groove and is connected to the guide groove.

[0011] A further improvement is that the adjustment mechanism includes a slide groove on one side of the upper end of the tilting arm, the extension arm is slidably mounted on the tilting arm through the slide groove, and an oblong hole communicating with the slide groove is provided on the other side of the upper end of the tilting arm. A fixing bolt is slidably mounted in the oblong hole and is threadedly connected to the extension arm. A marking line is provided on the upper side of the slide groove.

[0012] A further improvement is that the positioning mechanism includes a positioning pin, a second mounting hole is provided on the positioning bracket, the positioning pin is movably disposed in the second mounting hole, a positioning spring is sleeved on the positioning pin, and the two ends of the positioning spring are fixedly connected to the outer wall of the positioning pin and the inner wall of the second mounting hole, respectively.

[0013] A further improvement is that the clamping mechanism includes a positioning seat and a clamping seat fixedly installed on the base plate of the inspection fixture. The positioning seat and the inspection simulation block are located on the same straight line. The top of the positioning seat has a V-shaped surface structure. The clamping seat is located on one side of the positioning seat, and a clamp is rotatably installed on the clamping seat.

[0014] Further improvements include the installation of a go / no-go gauge on the base plate of the fixture, and the installation of a fixture calibration reference at the corner of the base plate.

[0015] The beneficial effects of this utility model are as follows: By setting an adjustment mechanism to adjust the position of the detection mechanism, the extension arm slides in the slide groove to adjust its position, which drives the detection pin to move together. At the same time, the fixing bolt moves in the waist-shaped hole to the corresponding marking line. Rotating the fixing bolt locks the position of the extension arm, which is convenient for position adjustment according to needs, meets various detection requirements, and can adjust the inspection tool according to the adjustment of the workpiece structure, thus reducing production costs.

[0016] By setting up a guide groove, guide block, and limit groove, the detection pin slides within the guide groove via the guide block. By rotating the detection pin, the guide block moves from the guide groove to the limit groove for limiting, allowing the detection pin to remain inserted without being pressed. Depending on the detection requirements, the detection pin can be pressed for detection and then quickly reset by the action of the detection spring, or it can be pressed and rotated to limit and maintain the insertion state. This allows for selection based on the detection needs, satisfying various usage requirements. Attached Figure Description

[0028] like Figure 1-6 As shown, a testing fixture for automotive dashboard crossbeam parts includes a fixture base plate 1, a go / no-go gauge 25 snapped onto the fixture base plate 1, and a fixture calibration reference 26 installed at the corner of the fixture base plate 1.

[0029] The base plate 1 of the fixture has two fixedly installed test simulation blocks 2 at both ends. The two ends of the crossbeam are placed on the test simulation blocks 2 at both ends. The base plate 1 has two clamping mechanisms in the middle. The clamping mechanisms are used to clamp the crossbeam. The clamping mechanisms include a positioning seat 22 and a clamping seat 23 fixedly installed on the base plate 1. The positioning seat 22 and the test simulation block 2 are on the same straight line. The top of the positioning seat 22 has a V-shaped surface structure. The clamping seat 23 is set on one side of the positioning seat 22. A clamp 24 is rotatably installed on the clamping seat 23. The crossbeam is placed on the V-shaped surface of the positioning seat 22. Rotating the clamp 24 on the clamping seat 23 clamps and fixes the crossbeam on the positioning seat 22.

[0030] like Figure 2As shown, a testing bracket 3 is provided on one side of the middle of the base plate 1 of the inspection fixture. A testing mechanism for testing the crossbeam is installed on the testing bracket 3. The testing bracket 3 includes a base 5 fixedly installed on the base plate 1 of the inspection fixture. A flipping arm 6 is rotatably installed on the base 5. The flipping arm 6 is T-shaped. The testing mechanism is located on one side of the flipping arm 6. The flipping arm 6 drives the testing mechanism to flip for testing. A locking bolt 7 is threadedly connected to one side of the flipping arm 6. A threaded connection hole is correspondingly opened on one side of the base 5. After the flipping arm 6 is flipped, it is locked to the base 5 by the locking bolt 7 threadedly connecting to the threaded connection hole, so that the position of the flipping arm 6 after flipping is fixed.

[0031] like Figure 4 , 5 As shown in Figure 6, the detection mechanism includes an extension arm 8 movably mounted on one side of the upper end of the flipping arm 6. Multiple extension arms 8 are provided. A first mounting hole 9 is provided on the extension arm 8. A detection pin 10 is movably inserted through the first mounting hole 9. An operating button 11 is installed on the top of the detection pin 10. The operating button 11 facilitates the pressing and rotation of the detection pin 10. A detection spring 12 is sleeved on the detection pin 10. The two ends of the detection spring 12 abut against the extension arm 8 and the operating button 11, respectively. The extension arm 8 is flipped to the upper side of the crossbeam and fits against it through the flipping arm 6. The detection pin 10 is pressed and inserted into the detection hole on the crossbeam for detection. After the detection is completed, the detection pin 10 is released. The detection pin 10 is separated from the detection hole and reset by the action of the detection spring 12.

[0032] A guide groove 13 is provided on the inner wall of the first mounting hole 9. A guide block 14 is fixedly connected to the side wall of the detection pin 10. The guide block 14 is slidably disposed in the guide groove 13. A limiting groove 15 is also provided on the inner wall of the first mounting hole 9. The limiting groove 15 is provided on one side of the guide groove 13 and is connected to the guide groove 13. When the detection pin 10 is pressed, the detection pin 10 is guided to move in the guide groove 13 by the guide block 14, so that the detection pin 10 moves vertically downward. When it is necessary to maintain the insertion state, after the detection pin 10 is inserted into the detection hole, the detection pin 10 is rotated so that the guide block 14 rotates into the limiting groove 15, which limits the position of the detection pin 10 and keeps the detection pin 10 in the insertion state.

[0033] like Figure 5As shown, the detection bracket 3 is equipped with an adjustment mechanism for adjusting the position of the detection mechanism. The adjustment mechanism includes a slide groove 16 on one side of the upper end of the flip arm 6. The extension arm 8 is slidably mounted on the flip arm 6 through the slide groove 16. An oblong hole 17 communicating with the slide groove 16 is opened on the other side of the upper end of the flip arm 6. A fixing bolt 18 is slidably mounted in the oblong hole 17. The fixing bolt 18 is threadedly connected to the extension arm 8. A friction plate is provided on the side of the fixing bolt 18 that contacts the flip arm 6. A marking line is provided on the upper side of the slide groove 16. The extension arm 8 slides and adjusts its position in the slide groove 16 according to the marking line, thereby driving the detection pin 10 to adjust its position. The fixing bolt 18 slides in the oblong hole 17 as the extension arm 8 slides. After the extension arm 8 moves to the designated position, the fixing bolt 18 rotates and fits against the side of the flip arm 6 to lock the position of the extension arm 8.

A positioning spring 21 is sleeved on the positioning pin 19. The two ends of the positioning spring 21 are fixedly connected to the outer wall of the positioning pin 19 and the inner wall of the second mounting hole 20, respectively. The positioning pin 19 is retracted into the second mounting hole 20 by manual pulling or the crossbeam is squeezed. The positioning hole angle of the crossbeam is rotated so that the positioning pin 19 enters the positioning hole to position the crossbeam.

[0035] During testing, the machined instrument panel crossbeam is placed on the V-shaped surface of the positioning seat 22, with both ends of the crossbeam placed on the test simulation blocks 2 at both ends. The positioning pin 19 is manually pulled back or compressed with the crossbeam, and then the positioning hole angle of the crossbeam is rotated so that the positioning pin 19 is inserted into the positioning hole to position the crossbeam. The clamp 24 is flipped and tightened to make the crossbeam stable. The flipping arm 6 is rotated to flip the crossbeam so that the extension arm 8 fits against the upper side of the crossbeam. The flipping arm 6 is locked with the locking bolt 7, and the test pin 10 is pressed to test the hole position. The go / no-go gauge 25 is removed to test the crossbeam profile and welded edge. After the test is completed, the locking bolt 7 and clamp 24 are loosened, the positioning pin 19 is pulled back, and the instrument panel crossbeam is removed to complete the test.
