The hydraulic pressure centre frame is located automatically by hydraulic pressure and is clamped blank workpiece, hydraulic unlock blank workpiece, but the roughness that is mated blank workpiece contact-making surface is necessary for below 1.6, blank workpiece contact-making surface there is higher requirement, during to the blank mating surface, must increase thick finish turning operation, improve the roughness of blank workpiece contact-making surface, prolonged process time.Increased processing cost.
Summary of the invention
It is the hydraulic pressure centre frame of blank that the utility model purpose provides a kind of roughness of blank workpiece contact-making surface, thereby solves blank workpiece long processing time, precision is not high, processing cost is high defective.
For achieving the above object, the utility model by the following technical solutions: it comprises support body, roof jack, blank workpiece, it is characterized in that: three roof jacks that evenly distribute on the sidewall of support body are inserted with the blank workpiece at the center of support body.
The sidewall of above-mentioned roof jack has inlet opening, the centre of roof jack is provided with screw rod, the upper end of screw rod is equipped with adjustable handle, and the lower end of screw rod is equipped with the magnesium iron slide block, and the outside of magnesium iron slide block is fixed with locking nail, be with the screw sliding sleeve around the screw rod, be provided with anti-switch block between screw sliding sleeve and the roof jack inwall, the bottom of roof jack is provided with friction top, and screw sliding sleeve upside appearance is equipped with piston rod, be provided with fairlead between piston rod and the roof jack inwall, be provided with spring between piston rod and the friction top.
The roughness of blank workpiece contact-making surface described in the utility model is the hydraulic pressure centre frame of blank, having three roof jacks adopts the spacing clamping of rotary fine adjustment hydraulic cylinder respectively, unclamps, the manual piston rod front end that can regulate again is equipped with magnesium iron to be inserted (roughness that is suitable for mating surface is a blank), thereby reaches the purpose at adjustment center.
The job order of this utility model hydraulic pressure centre frame is to pressurize to hydraulic cylinder earlier, makes piston rod reach the limit of the position, and thick then center, school is followed release, loaded onto part, and part is embraced in pressurization simultaneously once more, and last manual fine-tuning is to the center.
Use principle of the present utility model
1, give the hydraulic pressure high pressure at the housing inlet opening of roof jack, piston rod arrives the downward extreme position of piston rod movement under the effect of hydraulic pressure.Piston rod drives screw rod, and in the downward axially-movable of gathering sill, in the also axially-movable downwards of magnesium iron slide block that the screw sliding sleeve is installed, after pressing, the blank workpiece is withstood in three piston forward end motions simultaneously by anti-switch block for screw rod drive screw sliding sleeve, screw sliding sleeve.(clamping the blank workpiece)
2, turning handle drives screw rod and rotates, and makes screw slide over the effect lower edge gathering sill axially-movable of anti-switch block.The also bi-directional axial motion of magnesium iron slide block that fine setting is installed at the screw sliding sleeve, up to the appropriate location for well.(adjustment makes magnesium iron slide block contact blank workpiece tightness and center) manual fine-tuning
3, remove the hydraulic pressure high pressure of giving at the housing inlet opening of roof jack, piston rod is got back to the upwards extreme position (unclamping the blank workpiece) of motion under the effect of spring.Piston rod drives screw rod, and screw rod drives the screw sliding sleeve, the screw sliding sleeve by anti-switch block in the gathering sill axially-movable that makes progress, the also upwards axially-movable (unclamping the blank workpiece) of magnesium iron slide block of installing at the screw sliding sleeve.
The utility model compared with prior art has following advantage:
1, the roughness with described blank workpiece contact-making surface is the hydraulic pressure centre frame of blank, by the spacing clamping of hydraulic cylinder, unclamp;
2, by manual fine-tuning centering center accurately and rapidly;
3, the piston rod front end is equipped with lubricated magnesium iron slide block (being suitable for the coarse blank that can be of mating surface), and parts fixation is convenient, and production efficiency improves, and the coarse blank that can be of mating surface also can be roughness below 1.6, range of work highly versatile.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of roof jack.
The specific embodiment
As shown in Figure 1 and Figure 2 for a kind of roughness of mating surface be blank the hydraulic pressure centre frame it comprise support body 1, roof jack 2, blank workpiece 3, it is characterized in that: three roof jacks 2 that evenly distribute on the sidewall of support body 1 are inserted with blank workpiece 3 at the center of support body 1.
The sidewall of above-mentioned roof jack 2 has inlet opening 4, the centre of roof jack 2 is provided with screw rod 5, the upper end of screw rod 5 is equipped with adjustable handle 6, the lower end of screw rod 5 is equipped with magnesium iron slide block 7, the outside of magnesium iron slide block 7 is fixed with locking nail 8, be with screw sliding sleeve 9 around the screw rod 5, be provided with anti-switch block 10 between screw sliding sleeve 9 and roof jack 2 inwalls, the bottom of roof jack 2 is provided with friction top 11, screw sliding sleeve 9 upside appearances are equipped with piston rod 12, be provided with fairlead 13 between piston rod 12 and roof jack 2 inwalls, be provided with spring 14 between piston rod 12 and the friction top 11.
