Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to a calibration and inspection tool for a conveying skid used in an automated body conveying system of a vehicle factory. Background Art

[0002] The automotive sled equipment is mainly used in the production lines of welding, painting, and assembly in the automotive industry. Its main function is to transport workpieces and modules. Compared with other equipment, it has the advantages of low noise, high degree of automation, and reliable operation. The transported workpiece is placed on the sled body, realizing the "flexible transfer" during the transportation and transfer of the workpiece. However, during the production process, the sled equipment needs to be driven and stopped frequently, and even needs to be rotated 360 degrees in some special processes. These operations will cause a large amount of residual paint and welding damage to accumulate at the sled fulcrum. At the same time, the sled is also prone to jamming when passing through the track, causing the relative position of the car body and the spraying robot to change, thereby causing problems such as stagnation of the transportation line, scrapping of the vehicle, and even causing the production line to stop. Therefore, in order to effectively control the upstream and downstream processes of the automobile production line, the reliability of the automotive sled equipment has become a top priority. The sled equipment must be carefully inspected to ensure its normal operation during the production process.

[0003] The main frame of the adjustment fixture used in the existing conveyor sled is assembled with aluminum alloy profiles, and the positioning beam clamping structure uses a bent plate, which is welded on the legs and assembled with the main frame. The pin positioning holes are welded with steel and then processed and assembled on the main frame. The overall weight of the fixture is too heavy, close to 100kg. During the operation of the fixture, personnel are required to operate the fixture on both sides, lift the fixture and place it on the sled for inspection and adjustment. The workload of the operator is heavy and the efficiency is low. In addition, the rigidity of the fixture is poor. During the clamping of the positioning beam, if it is placed too skewed during clamping, the legs will bend, affecting the final inspection accuracy. Utility Model Content

[0057] like Figures 1 to 5 As shown, the conveyor skid calibration fixture 1 of the present invention includes a main frame 100, a longitudinal beam positioning member 200, a pin detection assembly 300 and a hand lift rod 400, Figure 1 , Figure 2 and Figure 6 The main frame 100 has a first direction X that is consistent with the longitudinal direction of the conveying sled 2 and a second direction Y that is consistent with the transverse direction of the conveying sled 2 .

[0058] like Figure 1 , Figure 2 and Figure 5 As shown, the longitudinal beam positioning member 200 includes a first longitudinal beam positioning member 210 and a second longitudinal beam positioning member 220 which are arranged opposite to each other. The first longitudinal beam positioning member 210 and the second longitudinal beam positioning member 220 are arranged opposite to each other at two ends of the bottom of the main frame 100 with the first direction X as the symmetry axis. Figure 6 The longitudinal beam positioning member 200 is used to enable the conveying slide calibration fixture 1 to position and detect the conveying slide 2 along the width of the longitudinal beam 21.

[0059] like Figure 1 and Figure 2 As shown, the pin detection assembly 300 is connected to the main frame 100 and includes a V-shaped detection block 310. Figure 6and Figure 7 The V-shaped detection block 310 is used to detect whether the position of the positioning pin 22 of the conveying slide 2 has deviation.

[0060] The hand-lifting rod 400 is connected to the main frame 100 and arranged along the second direction Y. Preferably, the hand-lifting rod 400 is two for operators to operate with both hands.

[0064] The second direction scale 330 includes a second direction scale and a second direction moving member 332. The second direction moving member 332 is used to drive the V-shaped detection block 310 to move along the second direction Y. The V-shaped detection block 310 moves along the second direction Y through the second direction moving member 332 until the V-shaped detection block 310 is matched with the positioning pin 22. The second direction scale can indicate the deviation of the positioning pin 22 along the second direction Y.

For example, a handle is provided on the top of the gauge self-checking rod 800 to facilitate taking and placing. When the gauge self-checking rod 800 is not needed, the gauge self-checking rod 800 is placed on the top of the main frame 100. When it is needed, the gauge self-checking rod 800 can be used to detect whether the distance between the two self-checking pin holes 110 is accurate to determine whether the gauge has structural deformation.

[0072] Furthermore, if Figure 1 and Figure 5 As shown, the longitudinal beam positioning member 200 of the conveying sled calibration fixture 1 also includes a connecting rod centering mechanism 230, which is connected to the first longitudinal beam positioning member 210 or the second longitudinal beam positioning member 220 to adjust the distance between the first longitudinal beam positioning member 210 and the second longitudinal beam positioning member 220 to improve the accuracy of positioning and detection.
