As shown in fig. 7 and 8, the linkage member 102 includes a fixed transverse plate 1022 fixedly connected to the bottom end of the rear surface of the connection seat 101, the fixed transverse plate 1022 vertically penetrates and is in threaded connection with a third adjusting screw 1021, the top end of the third adjusting screw 1021 is rotationally connected with a second mounting sleeve 1023, the upper surface of the second mounting sleeve 1023 is fixedly connected with a transmission wheel set 1024, the front surface of the transmission wheel set 1024 is rotationally connected with a second belt pulley 1026, the front surface of the second belt pulley 1026 is fixedly connected with a limiting shaft, the rear surface of the connection seat 101 is provided with a sliding groove (not shown in the drawing) adapted to the upper and lower sliding of the limiting shaft of the second belt pulley 1026, the bottom end of the rear surface of the connection seat 101 is rotationally connected with a first belt pulley 1025, a connecting shaft is arranged between the first belt pulley 1025 and the turntable 104, and belt transmission is performed between the first belt pulley 1025 and the second belt pulley 1026.
When the connecting slide block 724 slides from left to right on the connecting track 3, at this time, the third adjusting screw 1021 is rotated to push the transmission wheel set 1024 to approach the lower surface of the connecting track 3, so that the rollers on the transmission wheel set 1024 are clung to the lower surface of the connecting track 3, the transmission wheel set 1024 synchronously rotates, the turntable 104 is driven by the belt to rotate clockwise on the connecting seat 101, when the poking teeth 105 on the turntable 104 pass through the poking plate 92 in the rotating process, the poking teeth 105 generate upward thrust to the poking plate 92, the poking plate 92 drives the first fixing seat 91 to move downwards, the telescopic connecting rod 725 moves towards the inside of the connecting shaft 722, and the poking plate 92 is not pushed any more along with the rotation of the turntable 104 after the poking teeth 105 are separated from the poking plate 92, and the telescopic connecting rod 725 is quickly restored to the original position downwards due to elastic sliding connection between the telescopic connecting rod 725, so that the impact force is generated on the paint film of the test sample, and the strength of the paint film of the test sample under the impact force is realized.
The impact force test can be performed only when the link slider 724 slides from left to right.
The staff can carry out free combination test according to above-mentioned multiple test mode, carries out reasonable selectivity collocation as required to can obtain more comprehensive experimental data, at the in-process of experiment, the staff observes the paint film and changes, when the damage appears in the paint film, according to the data that the test set up, combines the paint film change condition, finally obtains the adhesive strength data of paint film.
When the test sample is specifically used, the connecting frame 22 is driven to lift upwards by stretching through the hydraulic telescopic cylinder 24 so as to conveniently place a test sample on the upper surface of the fixed plate 21, then the position of the limiting mechanism 8 on the base 1 is adjusted according to the size of the test sample, then the test sample is fixed on the fixed plate 21 through the limiting mechanism 8, then the connecting frame 22 is restored to the original position, at the moment, a paint film adhesion strength test is started on the test sample, after the connecting frame 22 is restored to the original position, the friction head 943 is abutted against the paint film on the surface of the test sample, the downward pressure of the friction head 943 on the paint film can be changed by placing the balancing weight 941 on the friction head 943, and the first electric sliding block 5 is used for driving the connecting sliding block 724 to slide from left to right in the connecting track 3 so as to carry out the adhesion strength test on the paint film in the left-right direction; meanwhile, when the connecting slide block 724 slides, the position of the toothed plate 61 is adjusted to enable the toothed plate 61 to be meshed with the gear 721, the adhesion strength test in the left-right direction can be carried out, the adhesion strength test in the circumferential direction can be carried out, the connecting track 3 is driven by the second electric slide block 46 to slide forwards and backwards on the displacement track 42, the adhesion strength test in the front-back direction is carried out on a paint film, when the first electric slide block 5 slides to the rightmost end on the connecting track 3, the position of the transmission wheel set 1024 is adjusted at the moment, the transmission wheel set 1024 rolls against the lower surface of the connecting track 3, the turntable 104 is driven to rotate, when the poking teeth 105 pass through the poking plate 92 in the rotating process of the turntable 104, the poking teeth 105 generate upward thrust to the poking plate 92, when the poking teeth 105 are separated from the poking plate 92, the poking plate 92 is quickly restored to the original position, the adhesion strength test is carried out on the paint film in an impact force mode, in the experimental process, workers observe the change of the paint film, and when the paint film is damaged, the adhesion strength data of the paint film are finally obtained according to the data set by the experiment and the change condition of the paint film.
