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.

Therefore, in order to avoid the influence on the finish machining of the camshaft hole due to the fact that the bolts are not in place, all the bolts of the camshaft seat cover on the cylinder cover need to be checked before the cylinder cover enters the finish machining machine tool, the bolts can be released after being in place, and the cylinder cover flows into the camshaft hole finish machining process.

However, in the prior art, the bolts are manually inspected one by one, that is, whether a gap exists between the nuts of all the bolts and the mounting surface of the camshaft seat cover is visually checked by human eyes, and if no gap exists, the bolts are mounted in place.

Obviously, the manual inspection mode is adopted, the labor intensity is high, if the inspection is carried out by a specially-assigned person, the labor cost is higher, therefore, in order to save the labor cost on a production line, an operator at an adjacent station usually carries out the concurrent inspection, namely, the operator comes once every few minutes to inspect the bolt and manually release the bolt, if the operator is delayed by other things and is not detected and released in time, the subsequent finishing machine tool is always in an idle running waiting state, the waste is caused, and the production efficiency is influenced.

In addition, the manual inspection inevitably has the phenomenon of missing inspection due to factors such as human negligence, that is, can not stop the bolt that is not in place from flowing into the camshaft hole finish machining process along with the cylinder cap.

In summary, those skilled in the art need to solve the above problems and to provide a cylinder head camshaft seat cover bolt in-place detection device capable of automatically detecting whether a camshaft seat cover bolt is screwed in place or not so as to prevent an unseen bolt from flowing into a camshaft hole finish machining process along with a cylinder head.

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.

It will be appreciated that the predetermined distance between the side shield 6 and the measurement shield 1 is determined by the distance between the bolt 91 and the side of the cylinder head 9 facing the side shield 6 to ensure that when the side of the cylinder head 9 is in abutting contact with the side shield 6, the bolt 91 is located just below the measurement shield 1.

The driving piece is used for driving the cylinder cover 9 to move towards the direction close to the side baffle 6, so that when the bolt 91 passes through the measuring baffle 1, the side edge of the cylinder cover 9 is in contact with the side baffle 6 in a fitting mode, and the accuracy of the position of the bolt 91 is ensured.

It can be understood that, since the height of the top point of the guide wheel 7 is higher than that of the roller 81 of the conveying device 8, when the front end of the cylinder cover 9 moves onto the guide wheel 7, the guide wheel 7 will lift up the cylinder cover 9, so that the cylinder cover 9 is supported by the guide wheel 7 and the two rear roller 81, at this time, the two rear roller 81 is a driving wheel to provide power for advancing the cylinder cover 9, and the guide wheel 7 is a driven wheel to define the orientation of the cylinder cover 9, so that the cylinder cover 9 is continuously moved toward the direction close to the side fence 6 under the combined action of the three-point support.

In this embodiment, the specific height difference between the height of the top point of the guide wheel 7 and the height of the top point of the roller 81 is not limited, and for example, the height difference between the two may be preferably 0.2 mm.

In addition, it can be understood that the axis of the guide wheel 7 is inclined toward the side guard 6 to gradually bring the cylinder head 9 closer to the side guard 6 by the guide wheel 7 and the roller 81 of the transfer device 8.

The present embodiment does not limit the specific value of the preset included angle between the axis of the guide wheel 7 and the axis of the roller 81, and preferably, the preset included angle between the axis of the guide wheel 7 and the axis of the roller 81 ranges from 30 ° to 45 °.

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.
