Description

Technical Field

[0001] This utility model relates to the field of testing tools, and in particular to a testing device for automotive support rods. Background Technology

[0002] As a key structural component of automobiles, the manufacturing precision of automotive support rods directly affects the assembly quality and performance of the entire vehicle. For example... Figure 1 As shown in the figure, an automotive support rod 10 is made of a round tube through stamping. Both ends are flat and have through holes 11 for connection with other components. Because this part has high requirements for fit and function in the vehicle system, its contour accuracy needs strict control. Therefore, a full inspection of the contour is required after stamping. Existing inspection methods mainly rely on conventional measuring tools such as vernier calipers and rulers. These tools require multiple positioning and manual readings during measurement, which is not only cumbersome and time-consuming but also prone to measurement errors due to human factors. Consequently, the inspection efficiency and accuracy cannot meet the needs of modern mass production. Therefore, it is necessary to develop a dedicated inspection device for the structural characteristics of this automotive support rod 10 to improve the convenience and accuracy of the inspection operation. Utility Model Content

The device uses a fixing mechanism to fix the automotive support rod to a placement reference surface, and uses go / no-go gauges to detect the gap between the tubular outer wall of the automotive support rod and the first and second reference surfaces. This allows for rapid detection of whether the contour of the part meets the processing requirements, thus improving detection efficiency and accuracy.

[0004] The detection device for an automobile support rod according to an embodiment of the present invention includes a base plate, a placement mechanism, a measuring base, and a fixing mechanism. A go / no-go gauge is detachably mounted on the base plate. The placement mechanism is mounted on the base plate and has a placement reference surface for placing the end of the automobile support rod. The measuring base is mounted on the base plate and has a first reference surface and a second reference surface corresponding to the tubular outer wall of the automobile support rod. The first reference surface and the second reference surface form a preset angle. The fixing mechanism is mounted on the base plate and corresponds to the placement mechanism. The fixing mechanism is used to fix the end of the automobile support rod to the placement reference surface. When the end of the automobile support rod is fixed to the placement reference surface, a gap is formed between the tubular outer wall of the automobile support rod and both the first reference surface and the second reference surface for detection by the go / no-go gauge.

The tubular outer wall of the automobile support rod forms gaps to be detected between the first reference surface and the second reference surface. At this time, the gaps corresponding to the first reference surface and the second reference surface can be detected by using go and no-go gauges to detect the tube body contour of the automobile support rod. If the go gauge end of the go and no-go gauge can pass through the gap and the no-go gauge end cannot pass through the gap, it is considered qualified. If the go gauge end cannot pass through or the no-go gauge end can pass through, it is considered unqualified. This allows for rapid detection of whether the contour of the part meets the processing requirements, which is beneficial to improving detection efficiency and detection accuracy.

[0023] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 A testing device for an automotive support rod includes a base plate 100, a placement mechanism 200, a measuring base 300, and a fixing mechanism 400. A go / no-go gauge 510 is detachably mounted on the base plate 100. The placement mechanism 200 is mounted on the base plate 100 and has a placement reference surface 201 for placing the end of the automotive support rod 10. The measuring base 300 is mounted on the base plate 100 and has a first reference surface 301 and a second reference surface 302 corresponding to the tubular outer wall of the automotive support rod 10. The first reference surface 301 and the second reference surface 302 form a preset angle. The fixing mechanism 400 is mounted on the base plate 100 and is corresponding to the placement mechanism 200. The fixing mechanism 400 is used to fix the end of the automotive support rod 10 to the placement reference surface 201. When the end of the automotive support rod 10 is fixed to the placement reference surface 201, a gap is formed between the tubular outer wall of the automotive support rod 10 and the first reference surface 301 and the second reference surface 302 for the go / no-go gauge 510 to detect.

[0024] Understandably, such as Figures 1 to 5As shown, the car support rod 10 is made of round tube by stamping. Its two ends are flat and inclined relative to the axis of the tube body. Its tube body cross section is elliptical or waist-shaped. The car support rod 10 is provided with through holes 11. The measuring base 300 is provided with an "L"-shaped stepped structure. The two sides of the "L"-shaped stepped structure are the first reference surface 301 and the second reference surface 302, respectively. In use, the end of the car support rod 10 is placed on the placement reference surface 201 of the placement mechanism 200 and fixed by the fixing mechanism 400. The tube body of the car support rod 10 is located at the measuring base 300. The tubular outer wall of the car support rod 10 forms gaps to be tested between the first reference surface 301 and the second reference surface 302. At this time, the go and no-go gauges 510 can be used to detect the gaps corresponding to the first reference surface 301 and the second reference surface 302 to detect the tube body contour of the car support rod 10. If the go gauge end of the go and no-go gauge 510 can pass through the gap and the no-go gauge end cannot pass through the gap, it is considered qualified. If the go gauge end cannot pass through or the no-go gauge end can pass through, it is considered unqualified. This can quickly detect whether the contour of the part meets the processing requirements, which is beneficial to improving the detection efficiency and detection accuracy.

[0025] In practical applications, the specific structures of the base plate 100, the placement mechanism 200, the measuring base 300, and the fixing mechanism 400 can be set according to actual usage needs. They will not be described in detail here, but will be explained in detail below.

[0026] In some embodiments, the placement mechanism 200 includes two supports 210, which are disposed on the base plate 100 and have a placement reference surface 201. The two supports 210 are respectively distributed at both ends of the vehicle support rod 10. The measuring base 300 is located between the two supports 210 and is inclinedly disposed on the base plate 100.

[0027] Understandably, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, two support seats 210 are respectively distributed near two diagonally opposite corners of the base plate 100. The placement reference surface 201 is located on the upper side of the support seats 210. A fixing seat 130 is provided on the base plate 100. The measuring base 300 is inclinedly set on the base plate 100 through the fixing seat 130 and located between the two support seats 210. In use, both ends of the car support rod 10 are placed on the placement reference surfaces 201 of the two support seats 210 respectively. Through the support at both ends, a relatively stable placement effect is achieved. In practical applications, in addition to the above structure, the car support rod 10 can also be placed by clamping and fixing one end and suspending the other end, or by setting a support structure in the middle of the measuring base 300 to fix the middle section of the car support rod 10. The specific configuration can be set according to the actual needs of use.

[0028] Further, two fixing mechanisms 400 are provided corresponding to the supporting base 210. It can be understood that as Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, by providing two fixing mechanisms 400, the two fixing mechanisms 400 are respectively used to fix both ends of the automobile support rod 10, so as to achieve a better fixing effect and reduce the possibility of looseness and displacement of the automobile support rod 10 during the measurement process using the go-no-go gauge 510.

[0029] In some embodiments, a go-no-go pin 520 is detachably arranged on the bottom plate 100, and the go-no-go pin 520 is used for measuring the through hole 11 at the end of the automobile support rod 10. It can be understood that as Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, in use, the end of the automobile support rod 10 is placed on the placement reference surface 201 of the supporting base 210, and the go-no-go pin 520 is inserted into the through hole 11 at the end of the automobile support rod 10. If the go end of the go-no-go pin 520 can be inserted into the through hole 11 and the no-go end cannot be inserted into the through hole 11, it is qualified; if the go end cannot be inserted into the through hole 11 or the no-go end can be inserted into the through hole 11, it is determined to be unqualified, thereby realizing the measurement of the through hole 11 at the end of the automobile support rod 10. In practical application, the specific structures of the go-no-go pin 520 and the go-no-go gauge 510 can be correspondingly set according to actual use requirements, and the measurement principle is known to those skilled in the art, so it will not be described in detail here.

[0030] Further, a positioning hole 202 is provided on the supporting base 210 at the placement reference surface 201, the positioning hole 202 is distributed corresponding to the through hole 11 at the end of the automobile support rod 10. The go-no-go pin 520 is provided with a positioning portion 521, and the positioning portion 521 can pass through the through hole 11 at the end of the automobile support rod 10 and be inserted and matched with the positioning hole 202, so as to position the automobile support rod 10 placed on the placement reference surface 201.

[0031] It can be understood that as Figure 2 and Figure 3As shown, both support seats 210 are provided with positioning holes 202 at their placement reference surfaces 201. The positioning holes 202 are distributed corresponding to the through holes 11 at the ends of the car support rod 10. The positioning part 521 is provided at the pin end of the stop pin 520. When the end of the car support rod 10 is placed on the placement reference surface 201, the stop pin 520 is first used to measure the through hole 11. After the measurement is qualified, the pin end of the stop pin 520 is inserted into the through hole 11 at the end of the car support rod 10, and the positioning part 521 is inserted into the positioning hole 202. This positions the end of the car support rod 10 placed on the placement reference surface 201, reducing the possibility of its displacement and avoiding affecting the subsequent measurement results. In practical applications, in addition to the above positioning structure, an abutment structure can also be provided on the support seat 210 corresponding to the end of the car support rod 10. The end of the car support rod 10 is positioned against the abutment structure. The specific configuration can be set according to the actual use requirements.

[0032] In some embodiments, a first shelf 110 for placing the stop pin 520 is provided on the base plate 100. It is understood that, as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the first storage seat 110 has an upward-opening "U"-shaped structure. The stop pin 520 is detachable from the base plate 100 by being placed on the first storage seat 110. Its structure is simple and easy to use. In practical applications, the first storage seat 110 can be equipped with a magnetic or clamping structure to fix the stop pin 520 placed on it. Alternatively, an elastic clip can be directly set on the base plate 100 to clamp and fix it, or a restraint strap can be set to restrain and fix it. The specific structure of the first storage seat 110 can be set according to the actual use needs.

[0033] In some embodiments, the fixing mechanism 400 includes a clamping tool 410 and a clamp support 420. The clamp support 420 is fixedly disposed on the base plate 100. The clamping tool 410 is connected to the clamp support 420 and can press the end of the automobile support rod 10 against the placement reference surface 201 of the support seat 210.

[0034] Understandably, such as Figure 2 , Figure 3 and Figure 5As shown, a lifting seat 220 is provided on the base plate 100. Of the two support seats 210, one is set on the base plate 100 via the lifting seat 220, and the other is directly set on the base plate 100. Of the two fixing mechanisms 400, one clamp support 420 is fixedly set on the base plate 100, and the other is fixedly set on the lifting seat 220. The clamping tool clamp 410 is connected to the clamp support 420. In use, by operating the clamping tool clamp 410, the end of the car support rod 10 placed on the placement reference surface 201 is pressed against the support seat 210, thereby fixing the end of the car support rod 10. Its structure is simple and easy to operate. In practical applications, in addition to the above structure, the fixing mechanism 400 may also include a driver and a pressure block. The driver drives the pressure block to move or rotate, so that the pressure block presses the end of the car support rod 10 against the support seat 210, thereby fixing the car support rod 10. The specific configuration can be set according to the actual use requirements.

[0035] In some embodiments, the clamping tool 410 is connected to a clamping block 430 for abutting against the end of the automotive support rod 10, and the clamping block 430 is provided with a relief groove 401 corresponding to the through hole 11 at the end of the automotive support rod 10. It is understood that, as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the clamping block 430 is provided with a clearance groove 401. In use, the positioning part 521 of the stop pin 520 is inserted into the positioning hole 202 to position the end of the car support rod 10. Then, the clamping tool clamp 410 drives the clamping block 430 to rotate until it abuts against the end of the car support rod 10. At the same time, the clearance groove 401 avoids the stop pin 520, thereby bringing the clamping position close to the through hole 11, achieving a better positioning and clamping effect. In actual applications, the specific structure of the clamping block 430 can be set according to the actual needs of use.

[0036] In some embodiments, a second shelf 120 for placing the go / no-go gauge 510 is provided on the base plate 100. It is understood that, as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the second storage seat 120 has an upward-opening "U"-shaped structure. The go / no-go gauge 510 is placed on the second storage seat 120, making it detachable from the base plate 100. Its structure is simple and easy to use. In practical applications, the second storage seat 120 can be equipped with a magnetic or clamping structure to fix the go / no-go gauge 510 placed on it. Alternatively, an elastic clip can be directly installed on the base plate 100 to clamp and fix it, or a restraint strap can be installed to restrain and fix it. The specific structure of the second storage seat 120 can be set according to the actual use requirements.

[0037] In some embodiments, a handle 140 is provided on the side of the base plate 100. It is understood that, as Figure 2 , Figure 3 and Figure 4 As shown, handles 140 are provided on both the front and rear sides of the base plate 100. The handles 140 facilitate the handling and turnover of this device, making it convenient to use. In actual applications, the handles 140 can be configured according to actual usage needs.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
