Problems solved by technology
At present, there is no universal main bracket (double support) performance inspection tool in the electric vehicle industry. The existing main bracket inspection tool is a special inspection tool, which can only simply detect the size of each installation point of the main bracket, and cannot detect the height difference between left and right, coaxial degree, parallelism and other performance errors
Excessive left and right height difference errors of the main bracket will cause the vehicle to be parked on one side. Excessive errors in the coaxiality and parallelism of the main bracket will cause the left and right limits of the main bracket to be asymmetrical, affecting parking stability.

Embodiment Construction
[0013] Such as figure 2 , 3 The general inspection tool for the performance of the main bracket of an electric vehicle is shown, which includes an underframe 202; a guide block 201 is provided on one side of the underframe 202. A reference shaft 101 for fixing the left and right lugs of the main bracket is arranged above the guide block 201 . Below the reference shaft 101, there are left and right lug parallelism detection blocks 103 that can move up and down along the guide block 201. The left and right lug parallelism detection blocks 103 are positioned on the guide block 201 by positioning screws. The upper plane of the parallelism checking block 103 is parallel to the axis of the reference axis 101 . The reference shaft 101 is covered with two steel sleeves 102 that can move axially along the reference shaft 101 , and the side end surfaces of the two steel sleeves 102 are perpendicular to the axis of the reference shaft 101 . Two sides of the middle part of the bottom ...

The invention discloses a general electric car main support performance test tool. The general electric car main support performance test tool comprises an underframe, wherein one side of the underframe is provided with a guide block, an upper portion of the guide block is provided with a basic shaft used for fixing a main support and left and right lugs, the lower portion of the basic shaft is provided with a left and right lug parallelism detection block capable of moving up and down along the guide block, an upper plane of the left and right lug parallelism detection block is in parallel with a shaft line of the basic shaft, two sides of the middle portion of the underframe are respectively provided with one left and right tube height difference detection block, the other side of the underframe is provided with a connection block moving along a sliding rail, the connection block is provided with a left and right bottom board height difference detection block, two side planes of the left and right bottom board height difference detection block are in parallel with the shaft line of the basic shaft, a lower portion of the left and right bottom board height difference detection block is provided with a pointer, and the sliding rail is provided with scale marks. The general electric car main support performance test tool is advantaged in that parameters such as left and right mounting hole coaxiality, left and right lug parallelism, left and right lug inner edge bottom fork error values, U-shaped tube left and right tube height error values, main support effective height and tube bottom portion height errors can be detected, and strong versatility is realized.
Description
technical field [0001] The invention relates to a checking tool for an electric vehicle, in particular to a universal checking tool for the performance of the main bracket (double support) of the electric vehicle. Background technique [0002] Electric car main support (double support) such as figure 1 As shown, it includes left and right lugs 1, U-shaped pipes 2 and left and right bottoms 3. At present, there is no universal main bracket (double support) performance inspection tool in the electric vehicle industry. The existing main bracket inspection tool is a special inspection tool, which can only simply detect the size of each installation point of the main bracket, and cannot detect the height difference between left and right, coaxial degree, parallelism and other performance errors. Excessive left and right height difference errors of the main bracket will cause the vehicle to be parked on one side. Excessive errors in the coaxiality and parallelism of the main bra...
