Background

At present, a camshaft seat cover on an engine cylinder cover is fixed on the cylinder cover through bolts, for example, the camshaft seat cover is fixed on the cylinder cover by adopting seven groups of bolt groups, wherein each group of bolt groups comprises three bolts. During installation, the bolts are screwed down through automatic screwing equipment.

However, due to equipment failure, human negligence, or the like, the bolts may be missed or not tightened in place, resulting in the unseen bolts flowing into the next process, that is, the camshaft hole finishing process, along with the cylinder head.

In the camshaft hole finish machining station, a cylinder cover is directly grabbed through a truss manipulator, and the cylinder cover is clamped on a clamp in a mode that a bolt mounting surface faces inwards and a fire face faces outwards. Because the space of the clamp is limited, when the bolt of the camshaft seat cover is screwed in place, after the cylinder cover is clamped, a tiny gap is formed between the top of the bolt of the camshaft seat cover and the bottom surface of the clamp, and the normal positioning and the attachment of the datum plane of the cylinder cover and the positioning surface of the clamp can be ensured.

However, when the bolts of the camshaft seat cover are not screwed in place, after the camshaft seat cover is clamped by the cylinder cover, the top of the bolt of the camshaft seat cover is in interference contact with the bottom surface of the clamp, so that the truss manipulator is stressed and deformed, and meanwhile, the cylinder cover reference surface cannot be attached to the clamp positioning surface.

The side baffle 6 is used for limiting one side of the cylinder head 9, and it can be understood that after the bolts 91 are tightened, the position of the bolts 91 relative to one side of the cylinder head 9 can be determined, so that the position of the bolts 91 in the conveying process is limited by limiting one side of the cylinder head 9 in the embodiment.

Specifically, the side barrier 6 is installed at one side of the conveying device 8, and preferably, the side barrier 6 corresponds to the measuring barrier 1, and a preset distance is formed between the side barrier 6 and the measuring barrier 1.

Further, considering that in practical applications, two kinds of bolts 91 with different heights are usually used for fixing the camshaft cover, for example, the camshaft cover fixing bolt 91 with rocker shaft is high, the ordinary camshaft cover fixing bolt 91 is low, and the two kinds of bolts 91 can be simultaneously present on the cylinder head 9, therefore, in order to adapt to this situation, on the basis of the above-mentioned embodiment, the bottom of the measurement baffle plate 1 is provided with the first spigot 12 and the second spigot 13, which are stepped, so that the first spigot 12 and the second spigot 13 can simultaneously detect the bolts 91 with two different heights.

That is, the first and second spigots 12 and 13 are different in height, one of the first and second spigots 12 and 13 is used for detecting the camshaft housing cover fixing bolt 91 with the rocker arm shaft, and the other is used for detecting the ordinary camshaft housing cover fixing bolt 91; the purpose of simultaneously detecting whether the bolts 91 with different heights are screwed in place by using one measuring baffle plate 1 is achieved.

It should be noted that, when the sensor 2 detects that the bolt 91 is not in place, the subsequent operation is not limited.

For example, preferably, on the basis of the above-mentioned embodiment, the sensor 2 is connected to a controller for controlling the start and stop of the transmission device 8, so that the controller controls the transmission device 8 to stop according to the detection signal of the sensor 2.

That is, when the sensor 2 detects that the bolt 91 is not in place, a non-in-place signal of the bolt 91 is sent to the controller, and the controller controls the transmission device 8 to stop so that the operator can timely handle the non-in-place signal.
