Detailed Description

Examples

The checking fixture mechanism suitable for the multi-vehicle type sledge comprises a roller bed, the sledge, a clamping mechanism and seven checking fixture assemblies. Wherein, the roller bed is installed at the bottom, and sled is placed to the top, and sled is carried and is followed its removal through the roller bed. The roller bed both sides fixed mounting have a base of examining, examine the top of base and install through examining a support and examine a subassembly with seven groups that the locating pin on the sled corresponds respectively. The middle position of one side of sled is installed with through motor drive's clamping device, clamping device arranges the below of roller bed in, the purpose is after sled stops to the sled stop position carry out the calibration, examine a subassembly and make sled accurate stop the back in place through clamping device, detect the locating pin on the sled through its pick-up plate through the bottom.

As shown in fig. 4 to 7, the seven groups of gauge assemblies are composed of the same detection assembly and detection plates with different shapes. The detection plates of the first and fourth groups of detection tool assemblies are identical in shape, the detection plates of the second and sixth groups of detection tool assemblies are identical in shape, and the shapes of the detection plates correspond to the positioning pins on the sledge, so that detection is facilitated.

The detection assembly sequentially comprises a spring upright post, a spring, a sliding mechanism and an L-shaped connecting plate from top to bottom. For ease of understanding, one side spring is omitted from fig. 4-6. The second and the third groups of gauge assemblies share one spring upright post, and other parts are arranged in a back-to-back manner. The spring stand column is vertically installed on a cross beam of the checking fixture base, the sliding mechanism is arranged on the side edge of the cross beam of the checking fixture base and comprises an installation plate vertically fixed on the cross beam of the checking fixture base, a linear guide rail is arranged on the installation plate, a connecting plate capable of moving up and down along the linear guide rail is arranged on the linear guide rail, and a handle is further arranged on the side edge of the connecting plate. The spring is arranged on the sliding mechanism and used for providing pulling force. The spring can make and examine a subassembly self return, and during the use through arm drop-down, overcome spring force, the hand loosens, and spring force area examines a subassembly and gets back to the normal position. The upper end of the spring is connected with a spring connecting plate fixed at the top end of the spring upright post, the lower end of the spring is hung on a mounting plate, and the tail end of the mounting plate is fixedly provided with a detection plate through an L-shaped connecting plate.

When the detection tool is used, the sledge is firstly transported to the detection tool roller bed from the turntable on the site operation box, when the sledge to be detected enters the sledge detection tool, the operation box operates the tightener to tighten the sledge so as to ensure that the sledge can be accurately stopped in place, and seven groups of positioning pins or supporting pins on the sledge respectively correspond to seven groups of detection tools on the detection tool; the pull-down handle is compared with the sled one by one respectively, and the required location and the support of all motorcycle types in the corresponding workshop are compared one by one, and whether the observation is unified is observed only by comparing the part to be inspected with the inspection tool on the inspection tool during operation. A gap of 2mm is allowed between each detection plate and the sled, and a place exceeding 2mm is a place needing to be modified. And adjusting the non-uniform sled workpiece according to the position of the checking fixture until the non-uniform sled workpiece is uniform with the checking fixture. And after the adjustment is finished, the adjusted sledge is put back to the machine conveying line on the operation box.

In the sled shown in the upper drawing, six types of vehicle can be simultaneously considered, wherein the second group, the fifth group and the sixth group of supporting pins are used for supporting the tray, the tray is a carrier tool with positioning pins and supporting pins, light truck types can be placed on the tray, and corresponding hole positions are arranged on the periphery of the tray and matched with the second group, the fifth group and the sixth group of supporting pins, so that the bearing of various vehicle types is completed; except for light truck models, other vehicle models are in direct contact with sledges, such as the first, third and fourth vehicle models, the first, third, fifth and seventh groups of supporting pins are used, the four groups of supporting pins respectively correspond to 8 hole sites or supporting points on the bottom plate of the white body, the 8 hole sites or supporting points play a role in supporting the whole white body, and the accuracy of the four groups of supporting pins can be checked and corrected through corresponding checking tools on the sledge checking tools; for the second vehicle type, because the body-in-white structure is different from the prior vehicle types, the second vehicle type uses four groups of support pins, namely a first group, a third group, a sixth group and a seventh group, wherein the four groups of support pins respectively correspond to 8 hole positions or support points of the body-in-white bottom plate, so that the whole body-in-white is supported; the fifth vehicle type, the body-in-white structure, differs from the previously mentioned vehicle types in that one, four, five, seven sets of support pins are used, again depending on 8 hole sites or support points for supporting the body-in-white.

In addition to the above embodiments, the present invention may have other embodiments. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
