Small rotary table, the small rotary table center are equipped with technique centre bore, and after procedure processing, the semicircle part 40 is located at institute
It states and forms one section of cylindrical portion on the end face of the outer one end of axis hole at center of arc, the cylindrical portion and the technique centre bore etc. half
The exterior arc surface outside of diameter, the semicircle part 40 forms the positioning knot extended from end face where the cylindrical portion to other end
Structure, after the cylindrical portion of the semicircle part 40 is packed into the technique centre bore of two jig main body 50, the pressure
Cover plate assembly 60 compresses the location structure and the semicircle part 40 is fixedly clamped, and two the second axle body 52 is used for lathe
Clamping.
The frock clamp is mainly used for semicircle part 40 described in clamping, especially blank using the semicircle zero of casting
Part 40, under main structure molding situation, the semicircle part 40 cannot use universal fixturing clamping.In the present embodiment
In, described 40 one end of semicircle part is fixedly clamped by one of fixture, cutter from 40 other end feed of semicircle part, when
It, will after the semicircle part 40 is located at the intrinsic design of part and the molding of process structure machining of the outer one end of one of fixture
Manufactured one end is fixed with two clamp, then the remaining unprocessed design of part of processing.Further, institute
The outer diameter for stating one of the first axle body 11 is greater than the outer diameter of one of the second axle body 12, and the outer diameter of two the first axle body 51 is big
In the outer diameter of two the second axle body 52.The frock clamp is in use, one of the second axle body 12 and described 2
Two axis bodies 52 are used for clamping machine tool, if clamping is on the scroll chuck of lathe, because the outer diameter of one of the second axle body 12 is less than
The outer diameter of one of the first axle body 11, the outer diameter of two the second axle body 52 are less than the outer of two the first axle body 51
Diameter, the scroll chuck can withstand the axial end of one of the first axle body 11 or two the first axle body 51, guarantee institute
State scroll chuck clamp the frock clamp position it is constant.

A cover clamp component 60 is arranged along the outer circle camber line of the semicircle part 40, is reliably fixed the semicircle part 40.
Further, compressed spring 70 is arranged on the long gland screw 61, and the compressed spring 70 is arranged in institute
It states between cover clamp 63 and two jig main body 50.The compressed spring 70 can be incited somebody to action when removing the long gland screw 61
The cover clamp 63 lifts, and is removed with facilitating.
Further, positioning screw 80, two fixture semicircle part described in clamping are provided on the small rotary table
When 40, the semicircle part 40 is leaned against in the positioning screw 80, it is dynamic to prevent rotation stop.
Further, the cylindrical portion is the inherent structure of the semicircle part 40 or the cylindrical portion is processed
Process structure in journey.When the cylindrical portion be the semicircle part 40 inherent structure, no matter the cylindrical portion design size
To be much, in a procedure, the radiuses such as the cylindrical portion and the technique centre bore be machined to, the cylindrical portion is made
The clamping that can be used for two fixture is machined to design size after the completion of two procedures, then by the cylindrical portion；When described
When not can be used for the cylindrical portion of clamping on semicircle part 40, the cylinder can be arranged in described 40 one end of semicircle part
Portion goes to folder position to the semicircle part 40 as process structure (i.e. folder position) after processing is completed.The location structure is institute
State semicircle part 40 inherent structure or the location structure be process in process structure, the location structure and
The cylindrical portion situation is similar, and so it will not be repeated.
Further, the frock clamp can also be used to clamping thin-walled semicircle part 40, the thin-walled semicircle part 40
Inner wall be arc surface.It is easily understood that the thin-walled semicircle part 40 is also easy to produce deformation, zero be attached on thin-walled is processed
Machining accuracy is often difficult to ensure when part structure.In the present embodiment, as shown in Figure 1, one of fixture further includes semicircle pressure
Block 30, the semicircle briquetting 30 is mounted on inside the thin-walled semicircle part 40, and the arc surface of the semicircle briquetting 30 and institute
The inner arc surface fitting of thin-walled semicircle part 40 is stated, withstands the semicircle after the first threaded hole described in 20 precession of fastening screw
Briquetting 30, and the semicircle briquetting 30 and the thin-walled semicircle part 40 are fixedly clamped.On the one hand the semicircle briquetting 30 may be used
It prevents the thin-walled semicircle part 40 from deforming, on the other hand can prevent the fastening screw 20 from weighing the thin-walled semicircle part 40 wounded
Inner surface.
