Description
Technical field
The utility model relates to a kind of valve seat machining tool more particularly to a kind of clamping dresses for processing square-outside and round-inside valve seat
It sets.
Background technique
Lathe, as with the tools such as lathe tool, drill bit, reamer, reamer, screw tap, screw die and annular knurl to the workpiece of rotation into
The lathe of row turnery processing, mainly by spindle box, change gear box, feed box, sliding box, knife rest, tailstock, feed rod, lead screw, bed
Body, cabinet base and cooling device composition.Wherein, spindle box is also known as headstock, for support and transmission main shaft drive workpiece rotate
Main motion specifically, main shaft passes through the fixtures clamping workpieces such as chuck, and drives workpiece rotation, to realize turning.Company is existing
Lathe is all made of air spider, which clamps work using moving radially for the movable jaw that is evenly arranged on chuck body
Part, can only processing excircles workpiece because develop it is a kind of can be used to clamp foreign side valve seat chuck or fixture it is imperative.
Summary of the invention
In place of solving the deficiencies in the prior art, the utility model provides a kind of structure and simply processes square-outside and round-inside valve
The clamping device of seat can realize turning effectively by square-outside and round-inside valve seat firm grip.
To achieve the goals above, the technology employed by the present utility model is a kind of processing square-outside and round-inside valve seat
Clamping device, including chassis are equipped with cylindrical body in chassis center, and the cylindrical body offers through slot in the axial direction, described logical
Cylindrical body is divided into the first semicolumn and the second semicolumn by slot, is movably installed in the inner wall plane of second semicolumn solid
Determine block, clamping screw is equipped with the opposite position in fixed block on the first semicolumn, for clamping valve seat.
Preferably, the clamping device further includes the clump weight that through slot bottom is arranged in, the clump weight is close to first
Semicircle column wall activity is fixed.
Preferably, the radius of first semicolumn is less than the second semicolumn.
Preferably, the fixed block is rectangular parallelepiped structure, the size of the fixed block can be according to the structure size of valve seat
To replace.
Preferably, the both ends of the surface in the fixed block are equipped with cylindricality deck, for reinforcing valve seat.
Preferably, the border on the chassis is equipped with mounting hole, for being assembled on main shaft.
Compared with prior art, the clamping device of the utility model, structure design advantages of simple, symmetrically, in use,
Clamping device is mounted on machine tool chief axis first, then successively valve seat is placed on fixed block, the cylindricality card on fixed block
Seat is caught in seat bottom portion just and is pre-machined in hole, then rotates the locking nut above the first semicolumn, valve seat is clamped solid
It is fixed, lathe can be opened, the process of valve seat is completed, which, which changes existing air spider, can only clamp outer round valve
The drawbacks of seat, so that whole process is simple, it is fast, time saving and energy saving, it greatly improves work efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1, chassis；2, through slot；3, the first semicolumn；4, the second semicolumn；5, fixed block；6, locking nut；7, match
Pouring weight；8, cylindricality deck；9, mounting hole.
Specific embodiment
It is below in conjunction with attached drawing and specifically real in order to keep the purpose of this utility model, technical solution and advantage clearer
Example is applied, clear, complete description is carried out to the technical solution of the utility model, it should be understood that preferred implementation described herein
Example is only used for describing and explaining the present invention, and is not used to limit the utility model.
The clamping device of the utility model is mainly used for the process of square valve seat in foreign side, is specifically assemblied in
On machine tool chief axis, play the role of fixed valve base, so that later period valve seat completes corresponding turning.
According to Fig. 1, the clamping device of this processing square-outside and round-inside valve seat, including chassis 1 are equipped in the center on chassis 1
Cylindrical body, the cylindrical body and chassis are integrally machined molding, offer through slot 2 in the axial direction in cylindrical body, and the through slot 2 is by cylinder
Body is divided into the first semicolumn 3 and the second semicolumn 4, is equipped with by screw for putting in the inner wall plane of the second semicolumn 4
The fixed block 5 of valve seat to be processed is set, which is designed as rectangular parallelepiped structure, which can design more according to valve seat size
It changes, increases height or width.On the first semicolumn 1, locking nut 6, the locking are equipped with the opposite position in fixed block 5
Nut can be rotated down upwards, for locking or unclamping valve seat.
In the present embodiment, after being assemblied in main shaft in order to ensure the clamping device, the second semicolumn configured with fixed block
It is located below, when design ensures that the radius of the first semicolumn 3 of top is less than underlying second semicolumn.
In order to ensure valve seat and main shaft keep same axis, clamping device further includes the clump weight 7 that through slot bottom is arranged in,
Clump weight is fixed close to the first semicircle column wall activity, can be replaced according to valve seat or fixed block size.
Meanwhile to avoid valve seat from flying out in high-speed rotation, in the outer end of fixed block, design has 2 cylindricality decks 8,
The cylindricality deck can be inserted into in the hole that is pre-machined on valve seat, with this fixed valve base, in order to increase operation rate, in fixed block
The other end also is provided with 2 cylindricality decks, and abrasion is facilitated to replace.
In addition, the border on chassis is equipped with mounting hole 9, for being assembled on main shaft.
The specifically used method of the clamping device of this processing square-outside and round-inside valve seat is: first filling clamping device by mounting hole
It is fitted on machine tool chief axis, then successively valve seat is placed on the second semicircle column wall fixed block, passes through the cylindricality on fixed block
Locking nut above deck and the first semicolumn matches, and valve seat is fixedly clamped, and can open lathe, completes adding for valve seat
Work process.
