A kind of crossbeam fixture, including base, four pressing plate assemblies being fixed on base, four Auxiliary support assemblies, Two lateral support assemblies and at least one positioning pin；The rectangular distribution of line of four pressing plate assemblies, the pressing plate Assembly includes the stud being fixed on vertically on base, is set with compression spring, pressing plate and nut on the stud successively, described One end of pressing plate is sleeved on to be fixed on the column on base vertically, and supporting is fixed with the base of the lower section of the pressing plate other end Block, the clamp surface are equipped with long lumbar hole, and the stud is stretched out outside pressing plate by long lumbar hole；The total component of four Auxiliary supports The both sides of base are listed in, and it is opposite two-by-two；The Auxiliary support assembly includes the auxiliary support in inverted L-shaped, and passes through screw thread It is connected to the thimble of auxiliary support front end；The thimble vertically runs through auxiliary support, and is provided with the lower end of thimble Handle, T-nut is provided with the upper end of thimble；Described two lateral support assemblies are juxtaposed on two auxiliary of the same side Between support assembly, the lateral support assembly includes the side bearing in inverted L-shaped, and the front end of the side bearing passes through screw It is connected with supporting block.

Further, the both ends of the base are respectively fixed with two backing pins.

Further, the base is equipped with hanging ring.

Further, the positioning pin totally two.

The beneficial effects of the utility model are：The utility model has the advantages of simple structure, and operation facility, bottom is placed on by crossbeam On rest pad on seat, and connect with the supporting block of two lateral support assemblies, by adjusting four pressing plate assemblies by crossbeam Bottom plate is fixed, while coordinates positioning pin to carry out the free degree of positioning limitation crossbeam, then adjusts four Auxiliary support assemblies Thimble the top plate of crossbeam is pushed against, the protrusion height of thimble is adjustable according to the crossbeam of different height, has well adapting to property, It is completely fixed the crossbeam on fixture under the mating reaction of each assembly firm, workpiece produces when milling flat processing can be greatly decreased Vibrations；The novel in structural design of the utility model, can be with the crossbeam of clamping different height, can be preferably in concentrated processing Hold, reduce the equipment needed for processing crossbeam and operating personnel, improve production efficiency.

Embodiment

The utility model is described further below in conjunction with the accompanying drawings：

Referring to figs. 1 to a kind of crossbeam fixture shown in Fig. 4, including base 1, four pressing plates being fixed on base 1 are total Into 3, four Auxiliary support assemblies 4, two lateral support assemblies 5 and two positioning pins 6；The both ends of base 1 are respectively fixed with Two backing pins 2, and set four hanging rings 7 to facilitate handling.

The rectangular distribution of line of four pressing plate assemblies 3, the pressing plate assembly 3 include being fixed on base 1 vertically Stud 31, be set with compression spring successively on the stud 31（Omitted in figure, play support pressing plate 32, while pushing When facilitate deformation）, pressing plate 32 and nut 33, one end of the pressing plate 32 is sleeved on the vertical column 34 being fixed on base 1 On, rest pad 35 is fixed with the base 1 of the lower section of 32 other end of pressing plate, 32 surface of pressing plate is equipped with long lumbar hole 36, described Stud 31 stretches out 32 outer of pressing plate by long lumbar hole 36

Four Auxiliary support assemblies 4 are respectively in the both sides of base 1, and opposite two-by-two；The Auxiliary support assembly 4 wraps The auxiliary support 41 in inverted L-shaped is included, and is threadedly attached in the thimble 42 of 41 front end of auxiliary support；The thimble 42 is along perpendicular Nogata is provided with handle 43 to through auxiliary support 41, and in the lower end of thimble 42, and the handle 43 in the present embodiment is star-like Hand, easy to adjust 42 extension elongation of thimble, is provided with T-nut 44 in the upper end of thimble 42 and is locked.
