Detailed Description

The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

As shown in fig. 1 to 5, a special fixture for a chain clamp to mill a plane, the chain clamp includes a fixing portion 1 and a plurality of connecting support rods 2 connected with the fixing portion 1 to form a U-shaped groove structure, and a plurality of through holes 3 coaxially arranged are formed on the plurality of connecting support rods 2.

The fixing part 1 and the connecting support rod 2 are of an integrated structure, and one side, away from the connecting support rod 2, of the fixing part 1 is of a plane structure.

The special fixture comprises a machine bench vice 4 and a fixing plate 5, wherein a plurality of mounting holes 6 are formed in the fixing plate 5, threaded holes 7 matched with the mounting holes 6 are formed in a fixing end 8 of the machine bench vice 4, and the fixing plate 5 is fixedly connected with the fixing end 8 of the machine bench vice 4 through bolts penetrating through the mounting holes 6 and screwed in the threaded holes 7;

two have been seted up at least to mounting hole 6, and two mounting holes 6 are located the both ends of fixed plate 5 respectively, and here mainly guarantee that fixed plate 5 can be stable fixed with stiff end 8 of machine bench vice 4, further ensure when utilizing fixed plate 5 to fix a position the chain clamp, avoid fixed plate 5 to rock and lead to the chain clamp position to appear the deviation easily.

Still set up on fixed plate 5 a plurality ofly and connect 2 assorted fixed blocks 9 of branch, set up on fixed block 9 with through-hole 3 for the fixed orifices 10 of setting up with the axle center, the chain clamp is installed on fixed plate 5 through the locating lever 13 that runs through-hole 3 and fixed orifices 10 in proper order, and the one end application of force that the movable end 11 of machine bench vice 4 kept away from fixed plate 5 through the chain clamp is fixed the chain clamp.

The expansion end of machine bench vice 4 is the phase-match setting with fixed part 1 and keeps away from fixed plate 5 one side, it is planar structure all preferably, when fixing the chain clamp, the atress position of chain clamp is fixed part 1 one side of keeping away from connecting branch 2 respectively, and the position that connecting branch 2 is connected with fixed plate 5, consequently when exerting force, make 11 top place levels of expansion end of machine bench vice 4 be higher than the horizontal plane at fixed orifices 10 place, can ensure that the point of application of force of chain clamp both sides can be on the coplanar, and then can guarantee that fixed part 1 keeps away from one side of connecting branch 2 and hug closely movable end 11 of machine bench vice 4 all the time, thereby realize that the one side that the chain clamp needs to process can remain the horizontality throughout.

It should be noted that the horizontal plane of the top of the movable end 11 of the machine vise 4 is the same as the horizontal plane of the fixed hole 10, so as to avoid the problem that when a force is applied to the chain clamp through the movable end 11 of the machine vise 4, the direction of the supporting force applied to the chain clamp by the movable end 11 and the fixed end 8 of the machine vise 4 is not on the same horizontal plane, which further causes uneven force on the chain clamp, and the fixed portion 1 of the chain clamp can be shifted to one side.

Every two fixed blocks 9 are a set of fixed locating parts 12 that are used for carrying on spacingly to connecting branch 2, and two fixed blocks 9 in every fixed locating part 12 of group are equallyd divide and are located the both sides of connecting branch 2 respectively, and the interval between two fixed blocks 9 in the fixed locating part 12 is not more than 1mm with the difference of the width of connecting branch 2.

Ensure promptly that accessible fixed block 9 can carry on spacingly to a degree of freedom of connecting branch 2, guarantee when connecting the chain clamp at fixed plate 5 through locating lever 13, the problem that great rocking can not appear in it.

The positioning rod 13 is of a T-shaped structure, so that a user can conveniently disassemble and assemble the chain clamp.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
