The utility model discloses an anchor clamps, including flange, square cover, perpendicular locking screw, vertical gasket, horizontal gasket and horizontal locking screw, the flange clearing hole links to each other with lathe spindle flange dish, and square cover is in the same place with flange joint, and square cover is provided with the inner chamber, and the main part of valve plate is passed through gasket and locking screw and is fixed in the inner chamber of square cover. The utility model discloses a take the square anchor clamps of inner chamber to be used for the clamping of valve plate, adopt the gasket to adjust the position of valve plate in square cover inner chamber, adopt vertical locking screw and horizontal locking screw to compress tightly and fix, owing to place two locating surfaces in valve plate space all have the holding surface, therefore anchor clamps loading and unloading valve plate is convenient, and the location is accurate, and easy operation can improve machining efficiency, reduces workman's intensity of labour, and need not to set up the balancing weight, shakes for a short time during the gyration.
Description
Technical Field
The utility model belongs to the technical field of machining frock clamp, concretely relates to be used for valve plate boss, hole and internal screw thread adds clamping apparatus.
Background
In production practice, the rectangular parts of the turning valve plate are usually clamped and fixed by a four-jaw chuck, the clamping mode takes a lot of time in alignment, and the valve plate parts are longer, and the parts of the valve plate extend out of the jaws to be longer in the turning process, so that the rigidity of the valve plate in the turning process is poor, the vibration phenomenon is easily caused, the turning allowance is large, the labor intensity of workers is high, and the machining precision and the machining efficiency are lower. Patent No. 201220644827.2 discloses a flat valve plate car screw frock with screw location, clamp plate are fixed, though can show the degree of difficulty that reduces valve plate processing clamping location, but, the device adopts set screw location, the adjusting shim's of not being convenient for position, and when screwing up the clamp plate, the clamp plate takes place to rotate easily, in addition, still need set up the balancing weight in addition on the chuck.
Disclosure of Invention
The utility model aims to solve the technical problem that to the not enough of above-mentioned prior art, a be used for valve plate boss, hole and internal screw thread adds clamping apparatus is provided. The utility model discloses an anchor clamps loading and unloading valve plate is convenient, and the location is accurate, and easy operation can improve machining efficiency, reduces workman's intensity of labour, and need not the balancing weight on the chuck, and it is little to shake during the gyration.
In order to solve the technical problem, the utility model discloses a technical scheme is: the utility model provides a add clamping apparatus for valve plate boss, hole and internal thread which characterized in that, this anchor clamps have following characteristic:
The utility model provides an anchor clamps for valve plate boss, hole and internal thread processing, includes flange, square cover, perpendicular locking screw, vertical gasket, horizontal gasket and horizontal locking screw, the flange clearing hole links to each other with lathe spindle flange dish, and square cover is in the same place with flange joint, and square cover is provided with the inner chamber, and the main part of valve plate passes through the gasket and the locking screw is fixed in the inner chamber of square cover.
The valve plate is locked through a vertical locking screw and a horizontal locking screw.
The position of the valve plate in the square sleeve is adjusted through a vertical gasket and a horizontal gasket.
The valve plate is adjusted through vertical gaskets and horizontal gaskets with different thicknesses in the position of the square sleeve.
The cylindrical boss of valve plate needs processing is located the outside of square cover inner chamber.
Compared with the prior art, the utility model has the following advantage:
(1) The utility model discloses a take the square cover clamping valve plate of inner chamber, adopt the gasket to adjust the position of valve plate in square cover inner chamber, adopt vertical locking screw and horizontal locking screw to compress tightly and fix, owing to place two locating surfaces in valve plate space all have the holding surface, consequently make things convenient for location and adjusting shim, and positioning accuracy is high, and the processing clout is few, and machining efficiency is high, can reduce workman's intensity of labour.
(2) When the size of the reference surface of an individual valve plate deviates to some extent and a gasket needs to be added on the supporting surface, only one same gasket needs to be added in the symmetrical direction for balancing weight, and after the valve plate is positioned, the other two surfaces of the clamp are directly locked by screws, so that the fixation is convenient and reliable.
(3) The utility model discloses an in the square cover inner chamber of anchor clamps is put into with the main part of valve plate when anchor clamps use, the part that will process leaks out, and anchor clamps are reliable to the work piece clamping, and the monolithic stationary rigidity of work piece is big, and it is little to add vibrations man-hour, can improve the machining precision, need not to set up the balancing weight.
in conclusion, the clamp has the advantages of convenience in operation, accuracy in positioning, reliability in clamping and the like.
The technical solution of the present invention will be further described in detail with reference to the accompanying drawings and the detailed description.

Detailed Description
Example 1
The utility model provides an anchor clamps for valve plate boss, hole and internal thread processing, includes flange 1, square cover 2, perpendicular locking screw 3, vertical gasket 4, horizontal gasket 7 and horizontal locking screw 8, flange 1 clearing hole 9 links to each other with lathe spindle flange dish, and square cover 2 links together with flange 1, and square cover 2 is provided with the inner chamber, and the main part of valve plate 5 passes through the gasket and locking screw fixes in the inner chamber of square cover 2.
The valve plate 5 is locked by a vertical locking screw 3 and a horizontal locking screw 8.
The position of the valve plate 5 on the square sleeve 2 is adjusted by a vertical gasket 4 and a horizontal gasket 7 with different thicknesses.
The cylindrical boss 6 of the valve plate 5 is positioned outside the inner cavity of the square sleeve.
the utility model is used for valve plate boss, hole and internal screw thread adds clamping apparatus's working process does:
