The utility model discloses simple structure, the practicality is strong to positioning accuracy is high. The deep hole and the end face hole of 3 faces of cuboid are processed through a manual mode, the relative position precision and the roughness requirement of 3 holes are guaranteed through one-time clamping, and the device is convenient and fast and is easy to operate.
Description
Technical Field
The utility model belongs to the technical field of machine-building industry and automatic welding field are applicable to IC and equip, and precision finishing uses
Background
The valve body type part is a very important part in IC equipment, has a simple structure and strong functions, and is generally used for ventilation regulation in equipment. The roughness of the inner hole of the valve body is extremely high, generally at least within Ra0.1, the machining scheme of the hole with the strict roughness requirement for machining a machining cutter provides high requirements, and the existing clamp cannot meet the requirements.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a manual turning adds turning attachment who processes many face holes, this part are the cuboid, total three have the deep hole characteristic, the roughness processing of design requirement is not less than Ra0.2. if adopt milling process according to traditional mode, can realize a clamping, can time processing on horizontal machining center, nevertheless through the discovery of testing repeatedly, milling process adopts the shaping sword processing, its blade is worn and torn easily, can not realize batch production, and the cost is very expensive, economic nature is not high. Therefore, the lathe machining can show the economy, and the turning lines are uniform and smooth.
In order to realize the purpose, the utility model discloses a technical scheme is:
a lathe fixture for processing a plurality of holes by manual rotation comprises a chuck plate, a support block, a positioning block, a clamping block, a bolt and a rotating shaft; the supporting block is combined on the chuck through a screw; the positioning block is provided with a shaft hole and a positioning hole; the supporting block is connected with the positioning block through a rotating shaft in a shaft-coupling mode and is positioned through a bolt; the positioning block is connected with a clamping block through a bolt.
The utility model has the advantages that:
1. the utility model relates to a novel clamping mode can realize lathe work in the hole of different stations, through manual upset anchor clamps, guarantees that each station hole center can both the gyration to the concentricity of lathe centre of gyration.
2. Simple operation and strong functionality. The hydraulic automatic rotating lathe fixture is very expensive in manufacturing cost, although the hydraulic automatic rotating lathe fixture is a mature product, the range of parts which can only be processed is small, the hydraulic automatic rotating lathe fixture is expensive in maintenance and poor in economy, and the same function is achieved through a mechanical structure aiming at a mechanical lathe fixture of a certain valve part.
3. The lathe fixture for manually overturning and processing the multi-surface hole features can cover the center distance of each feature of a part, is simple to operate, and has efficiency not lower than that of an automatic overturning tool.
4. The utility model discloses simple structure, the practicality is strong to positioning accuracy is high, and the clamping simple operation only needs to rotate + bolt and can realize, and can reach stable locking effect, extension lathe multiaspect adds the design of anchor clamps through locking a M8 screw.

Detailed Description
The invention will be described in further detail with reference to the accompanying figures 1-9 and the reference numerals.
A lathe fixture for processing a plurality of holes by manual rotation comprises a chuck plate 1, a supporting block 2, a positioning block 3, a clamping block 4, a plug pin 5 and a rotating shaft 6; the supporting block 2 is combined to the chuck 1 through a screw; the positioning block 3 is provided with a shaft hole and a positioning hole; the supporting block 2 is coupled with the positioning block 3 through a rotating shaft 6 and positioned through a bolt 5; the positioning block 3 is connected with a clamping block 4 through a bolt.
The chuck 1 is clamped to the apparatus with a hydraulic three-jaw chuck, which is 45 steel.
The supporting block 2 ensures that the part is stable in rotation and is made of 45 steel.
The positioning block 3 fixes parts, the centers of 3 surfaces can be ensured to rotate around a rotation center, the hole centers of 3 surfaces can be coincided with the center of the chuck plate 1 only by rotating the positioning block by 90 degrees, and the material is 45 steel.
The bolt 5 is used for quickly positioning after rotating parts and adopts a Missimi high-precision positioning threaded knob pin.
The part is arranged on the positioning block and is locked by a 4-M4 screw, the feeler gauge checks whether a joint surface has a gap, and the part is quickly pressed by a pressing block through 4 special screws, so that the part is ensured to be pressed and jointed between the pressing block and the positioning block.
And finally, locking the tool by using an M8 socket head cap screw. The screw can be loosened and the positioning bolt can be lifted at every time, and the lathe machining of a plurality of stations can be completed by turning the clamp.
