[0002] The shock tower is a shock-absorbing component installed above the left and right front wheels of new energy vehicles. It is a key part connecting the shock absorber and the front body. Its dimensional accuracy affects the body accuracy of the entire vehicle. At present, the shock tower is mainly formed by high-pressure die-casting. The high-pressure die-casting process mainly undergoes two processes: high-speed filling and cooling and solidification. During the cooling and solidification process, the solidification and shrinkage of the alloy liquid will inevitably cause the casting to deform, requiring 100% inspection in the subsequent process. The commonly used inspection method for 100% inspection is to use a comprehensive inspection fixture for inspection, but the traditional inspection fixture has a complex structure, which makes the inspection efficiency extremely low, which is not conducive to the rapid qualitative and quantitative inspection of the shock tower.

The handle 901 and the tower top hole position detection pins 903 are arranged at the top and bottom ends of the tower top hole position detection block 902 in a one-to-one correspondence, and the positions of the three tower top hole position detection pins 903 on the tower top hole position detection block 902 correspond to the positions of the three tower top blind holes 13 on the shock absorbing tower.

[0062] The beneficial effect of adopting the above-mentioned preferred scheme is that the positions of the three tower top hole position detection pins on the tower top hole position detection block correspond one by one to the positions of the three tower top blind holes on the shock-absorbing tower, which is conducive to judging the position and hole depth of the tower top hole position detection pin inserted into the tower top blind hole. If the tower top hole position detection pin can be successfully inserted into the specified depth, it indicates that the position and depth of the tower top blind hole are qualified, otherwise it is unqualified.

[0063] Preferably, it also includes a go / no-go gauge, a triangular gap gauge and a test gauge detachably mounted on the top of the base 7 .

[0064] The beneficial effects of adopting the above-mentioned preferred scheme are: the go / no-go gauge is conducive to qualitative detection of the side and bottom surfaces of the matching surface of the fender mounting plate at the front end of the shock absorber tower and the matching surface of the functional mounting hole on the tower top at the middle end, so as to judge whether the relevant detection surfaces on the front end and the middle end of the shock absorber tower are qualified; the triangular gap ruler is conducive to quantitative detection of the side and bottom surfaces of the matching surface of the fender mounting plate at the front end of the shock absorber tower, the matching surface of the functional mounting hole on the tower top at the middle end and the circular hole on the tower top, so as to obtain specific error data; the detection table is conducive to quantitative detection of the lap matching surface of the cabin side beam at the rear end of the shock absorber tower, and judges whether the detection surface on the rear end is qualified and the error value through the gap value; the detachable installation on the top of the base is conducive to improving the convenience of taking and placing the detection tool.

[0065] The working process of the utility model is described below by an embodiment:

[0066] like Figures 1 to 13 As shown, first pull up the first lifting handles 204 in the four clamping mechanisms 2, so that the four positioning surfaces 10 on the shock absorbing tower are placed one by one between the support pins 205 and the clamping heads 206 in the four clamping mechanisms 2;

[0067] Then, the positioning pins 102 on the two positioning mechanisms 1 are inserted into the two positioning holes 11 on the shock absorbing tower one by one to position and tighten the shock absorbing tower;

[0068] Then, loosen the locking handle 302 to release the limit of the detection displacement block 304, pull up the second lifting handle 303, and move the detection displacement block 304 and the adaptation detection block 301 close to the front end of the shock absorber tower and the matching surface of the fender mounting plate, so that a gap is formed between the adaptation detection block 301 and the bottom and side surfaces of the matching surface of the front end of the shock absorber tower and the fender mounting plate. Use a go and stop gauge to detect these two gaps. If the go gauge is pass and the stop gauge is stop, it is qualified. Otherwise, it is unqualified. Use a triangular gap ruler to detect the gap value. The deformation value is obtained by subtracting the theoretical gap value from the measured gap value.

[0069] Then, according to the same operation, the adapter detection block on the first middle-end detection component 41 is brought close to the matching surface of the middle-end tower top functional installation hole of the shock tower, and the middle-end tower top functional installation hole matching surface of the shock tower is qualitatively and quantitatively detected by using the go / no-go gauge and the triangular gap ruler. At the same time, the gap between the middle-end detection block 422 and the tower top circular hole 12 is measured by using the triangular gap ruler. The measured gap value minus the theoretical gap value is the deformation value. If the deformation value is within the error range, it means that the deformation of the tower top circular hole 12 meets the requirements.

[0070] At the same time, the tower top hole position detection pin 903 can also be inserted into the tower top blind hole 13. If the tower top hole position detection pin 903 can be smoothly inserted into the specified depth of the tower top blind hole 13, it indicates that the position and depth of the tower top blind hole 13 are qualified, otherwise it is unqualified;

[0071] Then, loosen the first fixing nut 514 and the second fixing nut 524, and move the first detection movable block 515 and the second detection movable block 525 close to the overlap matching surface between the rear end of the shock tower and the cabin side beam, so that a gap is formed between the rear end detection block 516 and the overlap matching surface between the rear end of the shock tower and the cabin side beam, and insert the movable stylus on the detection table into the detection hole 517. The value read from the detection table is the deformation value. If the deformation value is within the error range, it means that the overlap matching surface between the rear end of the shock tower and the cabin side beam is qualified.

[0072] Now the shock tower test is complete. Reverse the above steps, remove the shock tower and then test the next shock tower.
