Description

Technical Field

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

[0002] like Figure 1 As shown in the figure, an automotive glass guide rail 10 with a strip-shaped groove structure has through holes 11 at its bottom wall. Both the bottom and side walls of the groove are designed with a certain degree of curvature. This automotive glass guide rail 10 is mostly manufactured using a stamping process. Because this part itself has high requirements for contour accuracy, its curvature dimensions need to be comprehensively inspected after stamping. However, this part has a double-curvature structure and a special shape, making it difficult to place stably on a plane during inspection. This results in cumbersome and time-consuming operation when using conventional measuring tools for curvature measurement, and it is prone to misjudgment due to unstable positioning. Overall, the inspection efficiency and accuracy are not ideal. Therefore, it is necessary to develop a dedicated inspection device for the structural characteristics of this automotive glass guide rail 10 to improve the feasibility and accuracy of the inspection operation. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a testing device for automotive glass guide rails. The device uses a fixing mechanism to fix the automotive glass guide rail into a receiving groove, and uses go / no-go gauges to detect the gaps between the outer wall of the automotive glass guide rail and the first, second, and third reference surfaces. This allows for rapid detection of whether the curvature dimensions of the part meet processing requirements, thus improving testing efficiency and accuracy.

[0004] The detection device for automotive glass guide rails according to an embodiment of the present invention includes a base plate, a first measuring base, a second measuring base, and a fixing mechanism. A go / no-go gauge is detachably mounted on the base plate. The first measuring base is fixedly mounted on the base plate and has a first reference surface and a second reference surface. The first reference surface corresponds to the sidewall of the groove of the automotive glass guide rail, and the second reference surface corresponds to the bottom wall of the groove of the automotive glass guide rail. The second measuring base is movably mounted on the base plate or detachably mounted on the base plate. The second measuring base has a third reference surface corresponding to the sidewall of the groove of the automotive glass guide rail. The second measuring base can cooperate with the first measuring base to form a receiving groove for the automotive glass guide rail to be placed in, with the first reference surface, the second reference surface, and the third reference surface forming a receiving groove. The fixing mechanism is mounted on the base plate and used to fix the automotive glass guide rail placed in the receiving groove. When the automotive glass guide rail is placed in the receiving groove, gaps are formed between the outer wall of the automotive glass guide rail and the first reference surface, the second reference surface, and the third reference surface for detection by the go / no-go gauge.

[0005] The detection device for automotive glass guide rails according to the embodiments of this utility model has at least the following beneficial effects: In use, the second measuring base is first engaged with the first measuring base, so that the first reference surface, the second reference surface, and the third reference surface form a receiving groove. The automotive glass guide rail is then placed in the receiving groove and fixed by a fixing mechanism. When the automotive glass guide rail is placed in the receiving groove, gaps to be detected are formed between the outer wall of the automotive glass guide rail and the first, second, and third reference surfaces. At this time, go and no-go gauges can be used to detect the gaps corresponding to the first and third reference surfaces to detect the curvature of the groove sidewall of the automotive glass guide rail. 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 a pass / fail test. If the go gauge end cannot pass through or the no-go gauge end can pass through, it is considered unqualified. After completing the inspection of the side wall curvature of the automotive glass guide rail, the second measuring base is disassembled, moved, or rotated to separate the second measuring base from the first measuring base, thereby exposing the gap between the second reference surface and the bottom wall of the automotive glass guide rail. At this time, the gap corresponding to the second reference surface can be checked using the go and no-go gauges to detect the curvature of the bottom wall of the automotive glass guide rail. If the go gauge end of the go and no-go gauges can 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 quick detection of whether the curvature dimension of the part meets the processing requirements, which is beneficial to improving inspection efficiency and accuracy.

The support block is used to support the automotive glass guide rail placed in the receiving groove, so that a gap is formed between the bottom wall of the groove of the automotive glass guide rail and the second reference surface for the go / no-go gauge to detect.

[0011] According to some embodiments of the present invention, the detection device for automotive glass guide rails further includes a positioning pin.

[0023] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 A testing device for automotive glass guide rails includes a base plate 100, a first measuring base 200, a second measuring base 300, and a fixing mechanism 400. A go / no-go gauge 510 is detachably mounted on the base plate 100. The first measuring base 200 is fixedly mounted on the base plate 100 and has a first reference surface 201 and a second reference surface 202. The first reference surface 201 corresponds to the sidewall of the groove of the automotive glass guide rail 10, and the second reference surface 202 corresponds to the bottom wall of the groove of the automotive glass guide rail 10. The second measuring base 300 is movably mounted on the base plate 100 or detachably mounted on the base plate 100. The second measuring base 300 has a corresponding... The third reference surface 301 is provided on the groove sidewall of the automotive glass guide rail 10. The second measuring base 300 can cooperate with the first measuring base 200 so that the first reference surface 201, the second reference surface 202 and the third reference surface 301 form a receiving groove for the automotive glass guide rail 10 to be placed. The fixing mechanism 400 is provided on the base plate 100 and is used to fix the automotive glass guide rail 10 placed in the receiving groove. When the automotive glass guide rail 10 is placed in the receiving groove, a gap is formed between the outer wall of the automotive glass guide rail 10 and the first reference surface 201, the second reference surface 202 and the third reference surface 301 for the go / no-go gauge 510 to detect.

[0024] Understandably, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the second measuring base 300 is located on the front side of the first measuring base 200. The front side of the first measuring base 200 has an "L"-shaped stepped structure. In the "L"-shaped stepped structure, the side facing the second measuring base 300 is the first reference surface 201, the upward-facing side is the second reference surface 202, and the side of the second measuring base 300 facing the first measuring base 200 is the third reference surface 301. When the second measuring base 300 mates with the first measuring base 200, the first reference surface 201, the second reference surface 202, and the third reference surface 301 form a U-shaped receiving groove. In use, refer to... Figure 2 and Figure 4First, the second measuring base 300 mates with the first measuring base 200, so that the first reference surface 201, the second reference surface 202, and the third reference surface 301 form a receiving groove. The automotive glass guide rail 10 is placed in the receiving groove and fixed by the fixing mechanism 400. When the automotive glass guide rail 10 is placed in the receiving groove, gaps to be tested are formed between the outer wall of the automotive glass guide rail 10 and the first reference surface 201, the second reference surface 202, and the third reference surface 301. At this time, the go / no-go gauge 510 can be used to detect the gaps between the first reference surface 201 and the third reference surface 301 to detect the curvature of the groove sidewall of the automotive glass guide rail 10. If the go gauge end of the go / 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. After completing the detection of the curvature of the groove sidewall of the automotive glass guide rail 10, refer to Figure 5 The second measuring base 300 is disassembled, moved, or rotated to separate it from the first measuring base 200, thereby exposing the gap between the second reference surface 202 and the bottom wall of the automotive glass guide rail 10. At this time, the gap corresponding to the second reference surface 202 can be detected using the go / no-go gauge 510 to detect the curvature of the bottom wall of the automotive glass guide rail 10. If the go gauge end of the go / 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 allows for quick detection of whether the curvature dimension of the part meets the processing requirements, which is beneficial to improving detection efficiency and accuracy.

[0025] In practical applications, the specific structures of the base plate 100, the first measuring base 200, the second 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 second measuring base 300 is rotatably connected to the base plate 100, and the second measuring base 300 can rotate to approach and cooperate with the first measuring base 200 or rotate away from the first measuring base 200.

[0027] Understandably, such as Figure 2 , Figure 3 and Figure 5 As shown, the second measuring base 300 is rotatably connected to the base plate 100. This allows the second measuring base 300 to be rotated to move closer to the first measuring base 200 to form a receiving groove, or to rotate away from the first measuring base 200 to expose the gap between the second reference surface 202 and the bottom wall of the groove in the automotive glass guide rail 10. This facilitates quick and easy detection of whether the curvature dimensions of the part meet the processing requirements, making it convenient to use. In practical applications, the second measuring base 300 can also be detachably mounted on the base plate 100, or it can be configured to move relative to the base plate 100, depending on the specific application requirements.

[0028] In some embodiments, the base plate 100 is provided with a connecting seat 110 and a rotating seat 120. The second measuring base 300 is fixedly connected to the rotating seat 120, and the connecting seat 110 is fixedly connected to the base plate 100 and rotatably connected to the rotating seat 120. One of the rotating seat 120 and the connecting seat 110 is provided with a locking member 121, and the other is provided with a corresponding locking hole 111 that cooperates with the locking member 121. When the second measuring base 300 rotates to cooperate with the first measuring base 200, the locking member 121 can cooperate with the locking hole 111 to restrict the rotation between the rotating seat 120 and the connecting seat 110.

[0029] Understandably, such as Figure 2 , Figure 3 and Figure 5 As shown, a fixed seat 130 is also provided on the base plate 100. Both the connecting seat 110 and the fixed seat 130 are fixedly provided on the base plate 100. The first measuring base 200 is fixedly connected to the fixed seat 130, the rotating seat 120 is rotatably connected to the connecting seat 110, and the second measuring base 300 is fixedly connected to the rotating seat 120. The locking member 121 is provided on the rotating seat 120 and is a threaded member. The locking hole 111 is correspondingly provided on the connecting seat 110 and is a threaded hole. When the second measuring base 300 rotates to engage with the first measuring base 200, the locking member 121 engages with the locking hole 111 threadedly. This restricts the relative rotation between the rotating seat 120 and the connecting seat 110, thereby fixing the position of the second measuring base 300 for easy use. In practical applications, the locking element 121 can also be a pin, and the locking hole 111 can be a plug hole. The locking element 121 can also be set on the connecting seat 110, in which case the locking hole 111 is set on the rotating seat 120 accordingly. The specific configuration can be changed according to the actual needs of use.

[0030] In some embodiments, the rotating base 120 and / or the connecting base 110 are provided with positioning blocks 112, which are used to position the second measuring base 300 when it rotates to a position that engages with the first measuring base 200. It is understood that, as Figure 5 As shown, the positioning block 112 is disposed on the connecting seat 110. When the second measuring base 300 rotates to engage with the first measuring base 200, the rotating seat 120 abuts against the positioning block 112, thereby positioning the rotational position of the second measuring base 300 for ease of use. In practical applications, the positioning block 112 can also be disposed on the rotating seat 120, or both the rotating seat 120 and the connecting seat 110 can be provided with positioning blocks 112. The specific structure of the positioning block 112 can be set according to the actual usage requirements.

[0031] In some embodiments, the second measuring base 300 is provided with a handle 310. It is understood that, as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a handle 310 is provided on the front side of the second measuring base 300. In use, the second measuring base 300 can be rotated by holding the handle 310, making it convenient for the measuring personnel to operate. In practical applications, the specific structure of the handle 310 can be set according to the actual needs of use.

[0032] In some embodiments, the first measuring base 200 is provided with a support block 210 at the second reference surface 202. The support block 210 is used to support the automotive glass guide rail 10 placed in the receiving groove, so that a gap is formed between the bottom wall of the groove of the automotive glass guide rail 10 and the second reference surface 202 for the go / no-go gauge 510 to detect.

[0033] Understandably, such as Figure 3 As shown, the support block 210 is set on the second reference surface 202. To ensure the stable placement of the automotive glass guide rail 10, the first measuring base 200 is provided with support blocks 210 at both ends of the automotive glass guide rail 10. In use, the automotive glass guide rail 10, placed in the receiving groove, is supported by the support blocks 210, forming a gap between the bottom wall of the groove and the second reference surface 202 for the go / no-go gauge 510 to inspect. Its structure is simple and easy to use. In practical applications, in addition to setting the support blocks 210, the automotive glass guide rail 10 can also be suspended and fixed in the receiving groove by the fixing mechanism 400, forming a gap between the bottom wall of the groove and the second reference surface 202 for the go / no-go gauge 510 to inspect. The specific structure, number, and position of the support blocks 210 can be set according to the actual needs of use.

[0034] In some embodiments, the detection device for the automotive glass guide rail further includes a positioning pin 520. The first measuring base 200 is provided with a positioning hole 203 at the second reference surface 202. The positioning hole 203 is distributed and arranged corresponding to the through hole 11 on the automotive glass guide rail 10. The positioning pin 520 can pass through the through hole 11 on the automotive glass guide rail 10 and be inserted into the positioning hole 203 to position the automotive glass guide rail 10 placed in the receiving groove.

[0035] Understandably, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the first measuring base 200 is provided with a positioning hole 203 at the second reference surface 202, and the positioning holes 203 are distributed corresponding to the through holes 11 on the automotive glass guide rail 10. When the automotive glass guide rail 10 is placed in the accommodating groove, the positioning pin 520 passes through the through hole 11 on the automotive glass guide rail 10 and is inserted and fitted with the positioning hole 203, thereby positioning the automotive glass guide rail 10 placed in the accommodating groove, reducing the possibility of its deviation and avoiding adverse effects on subsequent measurement results. In practical applications, in addition to the above positioning structure, positioning and supporting structures may also be provided at both ends of the automotive glass guide rail 10. When the automotive glass guide rail 10 is placed in the accommodating groove, both ends of the automotive glass guide rail 10 are positioned and supported by the positioning and supporting structures, which can be specifically set according to actual use requirements.

[0036] In some embodiments, the detection device for an automotive glass guide rail further comprises a go-no-go pin 530, wherein the go-no-go pin 530 is configured to measure the through hole 11 on the automotive glass guide rail 10. It can be understood that as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, during use, before positioning the automotive glass guide rail 10, or after positioning is completed and the automotive glass guide rail 10 is fixed by the fixing mechanism 400, the go-no-go pin 530 can be inserted into the through hole 11 on the automotive glass guide rail 10. If the go end of the go-no-go pin 530 can be inserted into the through hole 11 while the no-go end cannot be inserted into the through hole 11, the through hole 11 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, the through hole 11 is determined to be unqualified, thereby realizing the measurement of the through hole 11 on the automotive glass guide rail 10. In practical applications, the specific structures of the go-no-go pin 530, the go-no-go gauge 510 and the like can be correspondingly set according to actual use requirements, and the measurement principles thereof are known to those skilled in the art, so detailed descriptions are omitted herein.

[0037] In some embodiments, the fixing mechanism 400 comprises a pressing tool clamp 410 and a mounting base 420, the mounting base 420 is fixedly arranged on the bottom plate 100, and the pressing tool clamp 410 is connected with the mounting base 420 and can press the automotive glass guide rail 10 placed in the accommodating groove against the supporting block 210.

[0038] It can be understood that as Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the mounting base 420 is fixedly mounted on the base plate 100. The clamping fixture 410 is connected to the mounting base 420. In use, the clamping fixture 410 is operated to press the automotive glass guide rail 10, which is placed in the receiving groove, against the support block 210, thereby fixing the automotive glass guide rail 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 automotive glass guide rail 10 against the support block 210, thereby fixing the automotive glass guide rail 10. The specific configuration can be set according to the actual needs of use.

[0039] In some embodiments, a resilient clip 140 is provided on the base plate 100, and the go / no-go gauge 510 is detachably clipped into the resilient clip 140. It is understood that, as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the base plate 100 is provided with multiple elastic clips 140. The go / no-go gauge 510 is detachably clipped into the elastic clip 140. In use, the go / no-go gauge 510 can be quickly picked up and put away, and it is also convenient to fix it when not in use, making it easy to use. In actual application, the specific structure of the elastic clip 140 can be set according to the actual use needs. Its specific composition is known to those skilled in the art, so it will not be described in detail here.

[0040] 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.
