Preferably, a limiting claw 11 is left below the cover plate 8, and the limiting claw 11 defines the distance between the parts according to the external dimensions of the parts, so as to limit the displacement between the parts within a tolerance range.

Preferably, a handle 9 is fixed above the cover plate 8, so that the cover plate 8 can be conveniently opened and closed.

Preferably, the cover plate 8 is provided with a clearance hole protruding above the part, so that interference cannot be generated in the process of locking the bolt by the screwdriver head, and the cover plate can limit the displacement of the part below in the Z direction when the cover plate is covered.

Preferably, a right cover plate lower buckle 6 is fixed above the supporting block right 4, and the cover plate lower buckle 6 is a spring locking mechanism and can clamp the upper cover to prevent the upper cover from moving up and down.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses simple structure, easily installation, low in manufacturing cost has reduced the operation degree of difficulty, and opening and shutting of apron is not big to the influence of production beat, can effectual assurance below part can not produce big deflection and displacement, can satisfy the requirements for quality of follow-up station.
