Description
Technical field
The utility model belongs to the machining equipment technical field, relates in particular to a kind of ball valve moving block centre bore processing tool.
Background technology
Ball valve is in commercial production and daily life, to use more a kind of valve, is made up of structures such as valve body, dwang and moving blocks.Accompanying drawing 1 has promptly been showed the structure that is positioned at the inner moving block of ball valve body; Can find out; Moving block is processed to form by the raw material of a monoblock cuboid, and processing technology is: process symmetrical two inclined-planes earlier, use the machined into centre bore again; On milling machine, process the edge at last, finally form moving block finished product as shown in the figure.Because the raw material shape is also irregular, this fixes for it and difficulty has been brought in the location, does not also exist auxiliary this moving block of a kind of suitable frock on lathe, to process at present, and existing processing mode efficient is low, machining accuracy is difficult to guarantee.
The utility model content
The utility model provides a kind of simple in structure, ball valve moving block centre bore processing tool that processing effect is good for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Ball valve moving block centre bore processing tool comprises union chuck and claw thereof; On said two claws, be provided with fixture block, also be provided with arc groove, on said union chuck, also be provided with gripper shoe in the inner of said fixture block; This gripper shoe is provided with screwed hole; Be provided with caging bolt in the said screwed hole, its non-nut end is inside, the vertical and intersectant centerline of its center line and said two claws.
Its advantage and good effect are: owing to adopted above-mentioned design, the utility model is simple in structure.The design of fixture block and caging bolt has guaranteed the machining accuracy of centre bore to the fixing and good positioning effect of workpiece raw material.
Preferably: the nut of said caging bolt is positioned at the outside of said gripper shoe.
Preferably: said fixture block is fixed on the said claw through screw.
Preferably: said gripper shoe is fixed on the said union chuck through screw.
Description of drawings
Fig. 1 is the structural representation of ball valve moving block in the utility model;
Fig. 2 is the vertical view of the utility model;
Fig. 3 is the front view of the utility model.
Among the figure: 1, caging bolt; 2, gripper shoe; 3, union chuck; 4, fixture block; 5, claw.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
Fig. 1 is the structural representation of ball valve moving block in the utility model.Can find out that moving block is processed to form by the raw material of a monoblock cuboid, processing technology is: process symmetrical two inclined-planes earlier, use the machined into centre bore again, on milling machine, process the edge at last, finally form moving block finished product as shown in the figure.
See also Fig. 2 and Fig. 3, the utility model comprises union chuck 3 and claw 5 thereof.On two claws 5, be provided with fixture block 4, fixture block 4 is fixed through screw, and end also is provided with arc groove within it.On union chuck 3, also be provided with gripper shoe 2, adopt screw to fix, this gripper shoe 2 is provided with screwed hole; Be provided with caging bolt 1 in the said screwed hole; Its non-nut end is inside, and its nut is positioned at the outside of gripper shoe 2, the vertical and intersectant centerline of its center line and two claws 5.
The course of work of this instance: this processing tool is installed on the lathe spindle flange.The workpiece raw material is placed between two fixture blocks 4, regulates caging bolt 1 center of workpiece raw material is roughly overlapped with the center of union chuck 3, regulate claw 5 afterwards and inwardly make fixture block 4 clamping work pieces.Can start the processing that lathe carries out centre bore afterwards.
