With continued reference to fig. 1-2, optionally, in order to facilitate fixing of the engine oil collector 1, the engine oil collector detection device further includes a first support seat 7 and a second support seat 8, the first positioning pin 71 is arranged to penetrate through the first support seat 7 and to be inserted into the positioning hole at the mounting flange 11 end of the engine oil collector 1, and the second positioning pin 81 is arranged to penetrate through the second support seat 8 and to be inserted into the positioning hole at the oil suction disc 12 end of the engine oil collector 1, so that the two ends of the engine oil collector 1 are fixed, and the engine oil collector 1 is prevented from moving or deforming during detection, which results in inaccurate measurement results, and meanwhile, the connection between the engine oil collector 1 and the engine oil collector detection device is more stable.
With continued reference to fig. 1-2, the distance and position between the first and second mounting blocks 3, 4 that mate with the oil collector 1 may vary due to variations in the length of the oil collector within tolerances.

Optionally, the first mounting block 3 includes a first mounting block body 31 and a movable block 32 movably disposed on the first mounting block body 31, and the movable block 32 is configured to be fixedly disposed with the mounting flange 11. Further, the movable block 32 is slidably disposed on the first mounting block body 31, and a cross section of the sliding groove of the first mounting block body 31 is a trapezoid with a small top and a large bottom, so that the movable block 32 can only move along a direction in which the sliding groove extends.

In order to solve this problem, the bottom plate 2 has a first sliding groove 21 disposed along a first direction perpendicular to a center line of the first positioning hole, and the first positioning block 5 is slidably disposed on the first sliding groove 21. Since the first slide groove 21 is provided in the bottom plate 2, the first direction is parallel to the bottom plate 2. Whether the center lines of the first mounting hole and the first positioning hole coincide or not is judged by sliding the first positioning block 5 along the first direction, so that whether the engine oil collector to be detected is qualified or not is further judged. Specifically, the first positioning block 5 includes a third slider 52 slidably disposed on the first sliding groove 21 and a first positioning portion 51 fixedly disposed on the third slider 52. Alternatively, the cross section of the first slide groove 21 is formed in an inverted T shape so that the first slide groove 21 can move only in the direction in which the first slide groove 21 extends, that is, in the first direction. Optionally, the third slider 52 may be fixed to the bottom plate 2 by a locking pin penetrating through the bottom plate 2, so as to prevent a mis-touch operation, so that the position of the third slider 52 relative to the bottom plate 2 is kept fixed, and when the position needs to be adjusted, only the locking pin needs to be pulled out.

Similarly to the first slide groove 21 in which the first positioning block 5 is slidably disposed, the first slider 65 is slidably disposed in the first direction with respect to the positioning block body 62, so that the oil collector detection device can detect whether the second mounting hole is within the tolerance range.

If the partial outer wall of the oil absorption disc of the oil collector to be detected can be attached to the side wall of the accommodating groove 41, the shape and the relative position of the two ends of the oil collector to be detected can be shown to meet the design requirements. Alternatively, the movable block 32 may be fine-tuned within a tolerance range and a determination may be made as to whether the above-described conditions are met during movement of the movable block 32.

Further, a value can be preset according to the tolerance range, and if the distance between the first mounting portion and the first positioning portion 51 exceeds the preset value, it is also determined that the to-be-detected oil collector is unqualified, so that the to-be-detected oil collector with an excessively large distance between the first mounting portion and the first positioning portion 51 is detected and marked as unqualified.
