2. This frock clamp passes through the clearance realization between baffle and the connecting plate and to the centre gripping of engine shroud lateral wall, only centre gripping shroud's lateral wall, reduces the area of contact with the shroud to make things convenient for die-casting, improve die-casting efficiency.

Drawings

In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments described in the present application, and it is obvious for those skilled in the art to obtain other drawings based on the drawings without creative efforts.

Fig. 1 is a schematic structural view of a tooling fixture for an engine hood according to an embodiment of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

Referring to fig. 1, the tooling clamp for the engine cover in the embodiment includes a bottom plate 1 and a pair of vertical plates 2 symmetrically arranged on the bottom plate 1, wherein clamping devices 3 are respectively arranged on opposite end surfaces of the pair of vertical plates 2, the two clamping devices 3 are oppositely arranged, each clamping device 3 includes a transverse plate 301 and a connecting plate 302, baffle 303 and lead screw 304, diaphragm 301 is connected with riser 2 is perpendicular, be equipped with rectangular shape through groove 305 on diaphragm 301, through groove 305 runs through diaphragm 301's front and back terminal surface, both ends are equipped with lug 306 around connecting plate 302 bottom, connecting plate 302 is articulated with diaphragm 301 through the bolt 307 that runs through lug 306 and through groove 305, the port department of bolt 307 is equipped with first lock nut 308, be equipped with the through-hole 309 that runs through its left and right sides terminal surface on the connecting plate 302, lead screw 304 runs through behind the through-hole 309 with baffle 303 fixed connection, the one end that lead screw 304 is not connected with baffle 303 is equipped with complex second lock nut 310.
