Centering machine cover assembling tool structure

Abstract

The invention discloses a centering machine cover assembling tool structure comprising tool frames which are arranged in a bilateral symmetry mode, and the left side and the right side of the front portion of each tool frame are provided with a left side Z-direction positioning supporting block and a right side Z-direction positioning supporting block in a downward vertical protruding and extending mode correspondingly; a left Z-direction positioning mechanism and a right Z-direction positioning mechanism are arranged on the left side and the right side of the middle of the tool frame in a vertically downward protruding and extending mode correspondingly. A left side XY direction positioning mechanism and a right side XY direction positioning mechanism are arranged on the left side and the right side of the rear portion of the tool frame in a downward vertical protruding and extending mode correspondingly. By the adoption of the centering machine cover assembling tool structure, the difference between the left gap and the right gap is small after a machine cover is installed, and the centering performance of machine cover assembling is guaranteed; meanwhile, the size chain ring can be short, the precision in the Y direction is high, the influence of the machining process is small, and the adjustment workload is reduced; in addition, the quality cultivation process is convenient to debug, low in reworking cost, high in debugging efficiency and wide in applicability.

Description

technical field [0001] The invention relates to a fitting structure, in particular to a fitting structure for a neutral machine cover. Background technique [0002] With the rapid development of the automobile industry, consumers have higher and higher requirements on the appearance of automobiles, and the appearance of the whole vehicle directly affects consumers' evaluation of vehicles. In addition to the appearance design of the whole vehicle, the most important thing is the gap and surface difference. In addition to the control of the size tolerance of the parts and components and the control of the size link, the gap and surface difference of the whole vehicle should also consider the design of the equipment and the establishment of the positioning strategy of the equipment. , the design concept of the equipment and the rationality of the positioning strategy play a very important role. [0003] At present, the OEMs generally have the following problems with regard to ...

Problems solved by technology

[0005] ②The left and right front shock absorbers are welded by at least five upper parts stations from the single sub-assembly to the assembly and adjustment line. The dimensional chain is long and the cumulative error is large;

[0007] ④ After the machine cover is installed, the left side meets the product design requirements, and the right side is difficult to control due to the accumulation of tolerances, resulting in uneven gaps between the machine cover and the fenders, requiring a lot of adjustment work;

[0008] ⑤When the cumulative tolerance is large, a rigid adjustment is usually used to ensure that the cover is temporarily consistent with the gap between the left and right fenders. The hood is neutral and rebounds to the state before the adjustment again, seriously affecting consumers' evaluation of the vehicle
