Longer in part, in addition to having turning requirement to cylindrical, the endoporus of part, often there be small hole machined class part end face or side
It is required that；A kind of heavy CNC vertical turning machine with milling spindle and CF s functions is so accomplished by come while meeting these demands；
These big-and-middle-sized parts are fixed on rotary table, in turnery processing, and heavy CNC vertical turning machine milling spindle is installed
Fixed lathe tool, rotary table drives big-and-middle-sized parts rotation, and turnery processing is carried out to these workpiece using lathe tool；Processing this
When a little big-and-middle-sized parts end faces or side aperture, heavy CNC vertical turning machine milling spindle then needs to install milling cutter, drill bit simultaneously
And itself also need rotation, rotary table now must be fixed, first with CF axles by worktable rotary to needs angle
Degree, recycles braking device to fix workbench；Because heavy CNC vertical turning machine Z-direction up stroke is longer, only
Ram movement with milling spindle can not fully meet requirement, also require that crossbeam is moved up and down, but cross beam movement certain distance
Afterwards, it is necessary to be clamped in it on column guide rail, so having invented this device.
Utility model content
To overcome problems of the prior art, the utility model, which provides a kind of heavy type numerical control and founds car crossbeam, to be stopped tight dress
Put, compact conformation, save space, simple and reliable, regulation is accurate, and controllability is strong.
The technical scheme in the invention for solving the technical problem is：This kind of heavy type numerical control founds car crossbeam and stopped tight dress
Put, including crossbeam and column, crossbeam two ends are on column, and locating shaft is sold directly to households with positioning fixed seat positioning being fixed on crossbeam
There is the oily gap of appearance between column, between fixed seat and crossbeam, be provided with fixed seat in a groove, groove and piston is installed, it is living
Plug be fixed on locating shaft, a fuel feed hole is additionally provided with fixed seat, fuel feed hole is connected with groove, be provided with fuel feed hole into
Oil pipe, hydraulic oil, which can enter, to be held in oily gap and on effect and crossbeam.
Further, O-ring and anti-dust seal are provided between the locating shaft and fixed seat, and anti-dust seal is close to oil inlet pipe
Side, O-ring also is provided with O-ring away from oil inlet pipe side, locating shaft with piston space.
Further, O-ring and anti-dust seal are provided between the piston and fixed seat, and anti-dust seal is close to oil inlet pipe one
Side, O-ring is away from oil inlet pipe side.
Further, the piston is fastened on locating shaft by screw.
To sum up, above-mentioned technical proposal of the present utility model has the beneficial effect that：
Compact conformation, saves space, and simple and reliable, regulation is accurate, and controllability is strong.The big I of clamping force passes through regulating piston
Diameter and hydraulic oil pressure are controlled, it is ensured that while clamping, reduced the use of hydraulic oil, reduced the waste of resource.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
The partial enlarged drawing that Fig. 2 is A in Fig. 1；
The partial enlarged drawing that Fig. 3 is B in Fig. 1.
In figure：
1 locating shaft, 2O type circles, 3 anti-dust seals, 4 positioning direct selling, 5 fixed seats, 6 pistons, 7 crossbeams, 8 screws, 9 columns, 10

Embodiment
Feature of the present utility model and principle are described in detail below in conjunction with accompanying drawing 1-3, illustrated embodiment is only used for
The utility model is explained, protection domain of the present utility model is not limited with this.
As shown in figure 1, the utility model includes crossbeam 7 and column 9, crossbeam two ends are arranged on column.Locating shaft 1 is with determining
Position sells 4 directly to households and the positioning of fixed seat 5 is fixed between crossbeam and column, there is the oily gap 12 (such as Fig. 2) of appearance between fixed seat and crossbeam.
A fuel feed hole 13 is additionally provided with fixed seat, fuel feed hole 13 is connected with groove 11, and oil inlet pipe 10, hydraulic oil are provided with fuel feed hole
Can enter hold in oily gap 12 and act on on crossbeam.
O-ring 2 and anti-dust seal 3 are provided between locating shaft 1 and fixed seat 5, and anti-dust seal is close to oil inlet pipe side, it is O-shaped
Circle also is provided with O-ring away from oil inlet pipe side, locating shaft with piston space.
It is provided with fixed seat in a groove 11 (such as Fig. 3), groove and piston 6 is installed, it is fixed that piston is fastened on by screw 8
On the axle of position.O-ring and anti-dust seal are provided between the piston and fixed seat, and anti-dust seal, close to oil inlet pipe side, O-ring is remote
