Description

Technical Field

[0001] The invention relates to the field of automobile parts detection, and in particular to a vehicle drainage structure detection device and method. Background Art

[0002] With the rapid development of automobiles, precise control is required for each automobile module system, and the same is true for automobile drainage. The drain valve at the bottom of the automobile can achieve the maximum drainage opening in the case of heavy rain. When drainage is not required, the drain valve needs to be basically closed to prevent other debris from entering the sheet metal. Therefore, the drain valve is designed to be composed of a hard plastic combined rubber elastic material. In order to achieve precise production control of the rubber drain port size, it is necessary to detect the size data of rubber elastic parts and special-shaped structures.

[0003] Since the drain outlet of the drain valve is made of rubber material, the material properties cause the outlet to deform when subjected to force. When measuring, the existing detection device often applies a detection force on the drain outlet to cause it to deform, resulting in inaccurate product measurement. Summary of the invention

[0004] The purpose of the present invention is to provide a vehicle drainage structure detection device and method, which is used to solve the problem that when measuring, the detection force applied by the existing detection device often acts on the drainage port position of the rubber material, causing it to deform and resulting in inaccurate product measurement.

[0005] To achieve the above object, the present invention provides a vehicle drainage structure detection device, including a detection platform, on which are installed:

[0006] The detection fixing seat is arranged in the middle of the detection table and is used to place the drain valve;

[0007] The flipping and pressing mechanism, which is in multiple groups, is arranged on the peripheral side of the detection fixing seat and is used to fix the base of the drain valve;

[0008] The detection mechanism, which is divided into multiple groups, is arranged on the surrounding side of the detection fixing seat and is used to detect the drain outlet of the drain valve. It includes a supporting angle plate, the bottom of which is slidably installed on the detection platform, and the detection platform is provided with a positioning block for positioning the detection position of the supporting angle plate. The supporting angle plate is fixedly connected to the positioning block through a positioning piece, and a detection tool is installed on the upper end of the support angle plate. A rotating mounting disk is rotatably installed on the detection tool close to the side of the detection fixing seat, and it is limited and rotated by the limiting assembly on the detection tool, and a low force gauge is installed on the rotating mounting disk, and the probe of the low force gauge passes through the detection through hole opened on the rotating mounting disk.

[0009] As a further solution of the present invention, the positioning member is a locking push rod, the locking push rod is threadedly connected to the bottom of the supporting angle plate, and the positioning block is provided with a positioning hole for the end of the locking push rod to be inserted.

[0010] As a further solution of the present invention, the detection platform is provided with a high-precision guide rail which is slidably connected to the bottom of the supporting angle plate.

[0011] As a further solution of the present invention, the limit assembly includes a positioning bead, a spring and an adjusting bolt. The positioning bead and the spring are installed in the mounting hole on the side of the detection tooling through the adjusting bolt. The spring is used to support the positioning bead to extend out of the mounting hole. The side of the rotating mounting plate is provided with a plurality of positioning grooves for the positioning bead to be positioned and inserted into.

[0012] At the same time, the present invention also provides a vehicle drainage structure detection method, which is applied to the above-mentioned vehicle drainage structure detection device, comprising the following steps:

[0013] Move the multiple testing mechanisms on the testing table backward, open the flipping and clamping mechanism, fix the drain valve on the testing fixing seat, and fix the product through the surrounding flipping and clamping mechanism;

[0014] Push the detection mechanism to the detection position, and position and fix the support angle plate of the detection mechanism on the positioning block;

[0015] Assemble the corrected low force gauge on the rotating mounting plate. The rotating mounting plate can detect the dimensions of different surfaces of the drain valve drain outlet. The rotating mounting plate is positioned in conjunction with the limit assembly to adjust the detection position of the low force gauge.

[0016] After the detection is completed, unlock the positioning block and move the detection mechanism backward, withdraw the detection mechanism from the detection position, then flip the clamping mechanism and take out the drain valve.

[0017] Compared with the prior art, the present invention provides a detection fixing seat, a flipping and clamping mechanism and a detection mechanism. After the detection mechanism moves to the detection position, the corrected low force gauge is assembled on the rotating mounting disk, and the probe on the low force gauge contacts the drain outlet. The rotating mounting disk can detect the dimensions of different surfaces of the drain valve drain outlet, so that it can detect the size of the rubber material of the drain outlet, and the force applied by the probe of the low force gauge on the drain valve is reduced to avoid deformation of the drain outlet, thereby ensuring accurate dimensional measurement.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0024] like Figures 1 to 4 As shown, in an embodiment of the present invention, a vehicle drainage structure detection device includes a detection platform 1, on which a detection fixing seat 16 is installed, which is arranged in the middle of the detection platform 1 and is used to place a drain valve 2; a flip pressing mechanism 4, which is a plurality of groups, is arranged on the periphery of the detection fixing seat 16 and is used to fix the base of the drain valve 2; a detection mechanism 3, which is a plurality of groups, is arranged on the periphery of the detection fixing seat 16 and is used to detect the drain outlet of the drain valve 2, and includes a supporting angle plate 11, the bottom of which is slidably mounted on the detection On the test platform 1, a positioning block 6 for positioning the detection position of the support angle plate 11 is provided on the test platform 1, the support angle plate 11 is fixedly connected to the positioning block 6 through a positioning piece, a detection fixture 15 is installed on the upper end of the support angle plate 11, a rotating mounting disk 8 is rotatably installed on the side of the detection fixture 15 close to the detection fixed seat 16, and the rotating disk 8 is limited by the limiting assembly on the detection fixture 15, a low force gauge 9 is installed on the rotating mounting disk 8, and a probe 10 of the low force gauge 9 passes through the detection through hole opened on the rotating mounting disk 8;

[0025] Specifically, in the present invention, the number of the flipping and clamping mechanisms 4 and the detection mechanisms 3 are set to four groups, and the four groups of flipping and clamping mechanisms 4 are used to fix the base of the drain valve 2. The four groups of detection mechanisms 3 detect the detection points on the special-shaped surface of the drain outlet at four positions of the drain outlet. Of course, the actual number of the detection mechanisms 3 and the flipping and clamping mechanisms 4 can also be adjusted accordingly according to the actual detection requirements;

[0026] Furthermore, the present invention improves the size of the dial indicator probe head and the measuring force of the dial indicator so that it can detect the size of the rubber material of the drain outlet. The probe 10 adopts a diameter less than 2.0 mm, which improves the accuracy of the probe 10 and makes it suitable for the detection of special-shaped surfaces. The force applied to the product by the probe 10 during detection is reduced to avoid deformation of the drain outlet, thereby ensuring accurate dimensional measurement.

[0027] like Figure 3As shown, in the embodiment of the present invention, the positioning member is a locking push rod 7, and the locking push rod 7 is threadedly connected to the bottom of the supporting angle plate 11. The positioning block 6 is provided with a positioning hole for inserting the end of the locking push rod 7. The locking push rod 7 is used to fix the detection mechanism 3 at the detection position of the positioning block 6.

[0028] like Figure 3 As shown, in an embodiment of the present invention, the detection platform 1 is provided with a high-precision guide rail 5 which is slidably connected to the bottom of the supporting angle plate 11. The high-precision guide rail 5 supports the moving direction of the angle plate 11 for precise positioning, thereby ensuring the stability of the detection and enabling spatial avoidance when detecting other positions.

[0029] like Figure 4 As shown, in an embodiment of the present invention, the limit assembly includes a positioning bead 12, a spring 13 and an adjusting bolt 14. The positioning bead 12 and the spring 13 are installed in the mounting hole on the side of the detection tooling 15 through the adjusting bolt 14. The spring 13 is used to support the positioning bead 12 to extend out of the mounting hole. The side of the rotating mounting disk 8 is provided with a plurality of groups of positioning grooves for the positioning bead 12 to be positioned and inserted. According to the different detection surfaces of each detection position, 2 to 3 corresponding detection positioning grooves are designed on the rotating mounting disk 8. The positioning bead 12 is used to position each detection point for detection under the elastic force of the spring 13.

[0030] At the same time, the present invention also provides a vehicle drainage structure detection method, which is applied to the above-mentioned vehicle drainage structure detection device, comprising the following steps:

[0031] Move the multiple detection mechanisms 3 on the detection table 1 backward, open the flipping and clamping mechanism 4, fix the drain valve 2 on the detection fixing seat 16, and fix the product by the surrounding flipping and clamping mechanism 4; push the detection mechanism 3 to the detection position, and position and fix the supporting angle plate 11 of the detection mechanism 3 on the positioning block 6; assemble the corrected low force gauge 9 on the rotating mounting disk 8, and the rotating mounting disk 8 can detect the dimensions of different surfaces of the drain outlet of the drain valve 2. The rotating mounting disk 8 and the limit assembly are used to position the rotating mounting disk 8 to adjust the detection position of the low force gauge 9; after the detection is completed, unlock the positioning block 6 and move the detection mechanism 3 backward, withdraw the detection mechanism 3 from the detection position, and then flip the clamping mechanism 4 to take out the drain valve 2.

[0032] In summary, the present invention sets a detection fixing seat 16, a flipping and clamping mechanism 4 and a detection mechanism 3. After the detection mechanism 3 moves to the detection position, the corrected low force gauge 9 is assembled on the rotating mounting disk 8, and the probe 10 on the low force gauge 9 contacts the drain outlet. The rotating mounting disk 8 can detect the dimensions of different surfaces of the drain outlet of the drain valve 2, so that it can detect the size of the rubber material of the drain outlet, and the force applied by the probe of the low force gauge 9 on the drain valve 2 is reduced to avoid deformation of the drain outlet, thereby ensuring accurate dimensional measurement.

[0033] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
