DETAILED DESCRIPTION

[0021] In order to more clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0022] See also Figure 1-Figure 5 , a vehicle threshold beam size detection device, comprising a connecting frame 2 arranged above the vehicle threshold beam 1, an electric push rod 3 connected to the connecting frame 2, and a measuring needle 4 is arranged on the connecting frame 2;

[0023] It also includes a measuring rod 1 5, a measuring rod 2 6 and a measuring rod 3 7 which are swingably arranged on the connecting frame 2, one end of the measuring rod 1 5 is detachably abutted against one side of the automobile threshold beam 1, one end of the measuring rod 2 6 is abutted against the other side of the automobile threshold beam 1, and one end of the measuring rod 3 7 is abutted against one end of the automobile threshold beam 1;

[0024] The other ends of the measuring rod 1 5 , the measuring rod 2 6 and the measuring rod 3 7 are respectively arranged at the outer peripheral position of the measuring needle 4 and are in detachable contact with the measuring ball of the measuring needle 4 .

[0025] The connecting frame 2 includes a connecting frame 21 arranged above the door sill beam 1 of the automobile, a supporting frame 22 connected to the connecting frame 21, the electric push rod 3 is connected to the supporting frame 22, and the measuring needle is arranged on the supporting frame 22;

[0026] A hinge seat 211 is provided on the connecting frame 21, and the measuring rod 1 5, the measuring rod 2 6 and the measuring rod 3 7 are respectively connected to the connecting frame 21 through the hinge seat 211. The sides of the measuring rod 1 5, the measuring rod 2 6 and the measuring rod 3 7 are all connected to the tension springs 8, and the other ends of the three tension springs 8 are respectively connected to the sides of the connecting frame 21.

[0027] The angles between the contact ends of the measuring rod 1 5 , the measuring rod 2 6 , the measuring rod 3 7 and the measuring needle 4 are all 120 degrees.

[0028] The sides of the measuring rod 1 5 , the measuring rod 2 6 , and the measuring rod 3 7 that contact with the automobile door sill beam 1 are all arc-shaped.

[0029] The specific working process of this utility model:

[0030] When in use, firstly clamp the automobile threshold beam 1 with the clamp 9, and then drive the connecting frame 2 to descend through the electric push rod 3, so that the measuring rod 1 5, the measuring rod 2 6 and the measuring rod 3 7 on the connecting frame 21 are respectively in contact with the automobile threshold beam 1, and rotate along the hinge seat 211 to overcome the elastic force of the tension spring 8. When the electric push rod 3 continues to descend, the measuring rod 1 5, the measuring rod 2 6 and the measuring rod 3 7 continue to expand until the side parts of one end are respectively in contact with the side vertical parts of the automobile threshold beam 1;

[0031] See also Figure 5 At this time, the other ends of the measuring rod 1 5, the measuring rod 2 6 and the measuring rod 3 7 are respectively arranged at the peripheral position of the measuring needle 4 and are not in contact with the measuring ball of the measuring needle 4, and then the measuring machine is started, so that the measuring needle 4 contacts the side of the measuring rod 1 5, the measuring rod 2 6 and the measuring rod 3 7 in turn, thereby measuring the coordinates of the ends of the measuring rod 1 5, the measuring rod 2 6 and the measuring rod 3 7, and comparing them with the three pre-set standard values. If the deviation of the three measured coordinate values ​​from the standard value is greater than the set value, it means that the size measured by the corresponding measuring rod (measuring rod 1 5, measuring rod 2 6 or measuring rod 3 7) in the automobile sill beam 1 does not meet the requirements. After the measuring needle 4 transmits the signal to the controller, the controller sends a command to the signal indicator light, and the indicator light lights up red;

[0032] Similarly, if the deviation between the actual coordinate value measured by the measuring needle 4 and the standard value is less than the set value, the size of the corresponding position of the automobile sill beam 1 meets the requirements. After the measuring needle 4 transmits the data to the controller, the controller sends a command to the indicator light, and the indicator light lights up green; specifically, if the measuring needle 4 measures that the deviation of the measuring rod 1 5 and the measuring rod 2 6 is too large, it means that the deviation of the automobile sill beam 1 in the width direction is too large. If the measuring needle 4 measures that the deviation of the measuring rod 3 7 is too large, the deviation of the automobile sill beam 1 along the length direction is too large.

[0033] The electric push rod 3 drives the measuring rod 1 5 , the measuring rod 2 6 and the measuring rod 3 7 to contact the automobile door sill beam 1 at the same time, which reduces the displacement of the measuring needle 4 of the measuring machine, saves the measuring time, and the size detection of the automobile door sill beam is convenient and fast.

[0034] By providing a connecting frame 2 connected to the electric push rod 3, a measuring rod 1 5, a measuring rod 2 6 and a measuring rod 3 7 are respectively provided on the connecting frame 21 of the connecting frame 2. When the electric push rod 3 descends, the measuring rod 1 5, the measuring rod 2 6 and the measuring rod 3 7 are respectively in contact with the measuring ball of the measuring needle 4, so that the size detection of multiple surfaces of the automobile threshold beam 1 can be completed at one time, avoiding the use of the measuring needle 4 to detect the automobile threshold beam 1 multiple times, and the size detection of the automobile threshold beam 1 is convenient and fast;

[0035] The angles between the contact ends of measuring rod 1 5 , measuring rod 2 6 , measuring rod 3 7 and measuring needle 4 are 120 degrees, the force on the measuring ball of measuring needle 4 is more balanced, and the size detection of automobile sill beam 1 is more accurate; the side of measuring rod 1 5 , measuring rod 2 6 , measuring rod 3 7 that contacts with automobile sill beam 1 is arc-shaped, which plays a guiding role, and the contact between measuring rod 1 5 , measuring rod 2 6 and measuring rod 3 7 and the side of automobile sill beam 1 is smoother, and the size detection of automobile sill beam 1 is more convenient and quicker.
