Abstract
The utility model relates to a novel clamp holder for a guide rail, wherein the motions of piston rods at the both sides of a clamping body are hydraulically driven, and the piston rods push clamping blocks at the both sides to clamp the guide rail, thereby realizing the clamping for the guide rail. The novel clamp holder for a guide rail disclosed by the utility model has the advantages of being simple in structure, compact in layout, convenient in installation, small in volume, large in clamping force, without additional lateral force, low in maintenance cost, convenient for automatic control etc. The novel clamp holder for a guide rail reduces the load of transmission component, lessens the influence on machining accuracy by transmission accuracy, and ensures the machining accuracy of machine tool.
Description
Technical field
The utility model relates to a kind of novel guide rail clamper, specifically is applicable to the novel guide rail clamper that requirements such as machine tool, Digit Control Machine Tool are controlled guide rail, belongs to the frame for movement technical field.
Background technology
Along with the high speed development of China's mechanical industry, the especially development of high accuracy, heavily loaded Digit Control Machine Tool, more and more to the demand of Digit Control Machine Tool, simultaneously the technical parameter of equipment is had higher requirement.Concerning Digit Control Machine Tool, how to reduce to add the load of drive disk assembly in man-hour, reduce the influence of transmission accuracy to machining accuracy, realization is controlled movable body, ensures that the machining accuracy of lathe becomes the significant problem of pendulum in face of each lathe manufacturer.
In the existing machine tool guide rail, seldom see the guide rail clamper, all power are born by drive disk assembly entirely, have a strong impact on the service life of drive disk assembly and the machining accuracy of part; Though previous guide rail clamper can be realized the clamping to guide rail, volume is bigger, and guide rail clamper part processing precision is had relatively high expectations, and these are seriously restricting being widely used of it.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned weak point, thereby a kind of novel guide rail clamper is provided, and realizes the clamping of straight line or arc guide rail, has ensured the machining accuracy of lathe.
The technical scheme of the utility model is: a kind of novel guide rail clamper, and clamping body is fixed on the movable body through trip bolt; Spring is housed on the piston rod, and an O RunddichtringO is stuck in the rectangular channel of piston rod, and piston rod is contained in the plunger shaft of clamping body, has screwed hole on the clamp and is installed on the threaded rod of piston rod through it; Piston cap is installed on the clamping body through bolt, plain washer and spring washer is housed between bolt and the piston cap carries out lockingly, has the 2nd O RunddichtringO to seal between piston cap and the piston rod, has the 3rd O RunddichtringO to seal between piston cap and the clamping body; Have oil-in on the piston cap, hydraulic oil gets in the piston cylinder through oil-in.
Said both sides piston rod adopts same hydraulic power source to pressurize, and avoids the appearance of additional side force.
The quantity of said clamp can increase and decrease according to the size of required clamping force.
Said clamping body can be selected with the shape of guide rail, realizes the clamping of line slideway or arc guide rail.
On contacted of said clamp and the guide rail copper sheet is housed.
Compared with present technology the utility model has the following advantages:
The utlity model has simple in structure, compact in design, easy for installation, volume is little, clamping force is big, do not have additional side force, maintenance cost is low, be convenient to advantage such as automation control.Reduced the load of drive disk assembly, reduced the influence of transmission accuracy, ensured the machining accuracy of lathe machining accuracy.
Simultaneously the used clamp of the utility model with contacted of guide rail on copper sheet is housed, reduce the wearing and tearing of clamp to the guide rail side, protected guide rail.
Description of drawings
Fig. 1 is the vertical view of the utility model.
Fig. 2 is the left view of the utility model.
Fig. 3 is the A-A cutaway view of Fig. 1.
The specific embodiment
To combine accompanying drawing that the utility model is further described below:
Like Fig. 2, shown in Figure 3, comprise clamping body 1, clamp 2, piston rod 3, piston cap 4, spring 5, an O RunddichtringO 6, the 2nd O RunddichtringO 7, bolt 8, plain washer 9, spring washer 10, the 3rd O RunddichtringO 11, hydraulic circuit 12 etc.
The utility model mainly adopts clamping body 1 to be fixed on the movable body through trip bolt;
Spring 5 is contained on the piston rod 3, and an O RunddichtringO 6 is stuck in the rectangular channel of piston rod 3, and piston rod 3 is contained in the plunger shaft of clamping body 1, has screwed hole on the clamp 2 and is installed on the threaded rod of piston rod 3 through it;
Piston cap 4 is installed on the clamping body 1 through bolt 8; Plain washer 9 is housed between bolt 8 and the piston cap 4 to carry out locking with spring washer 10; There is the 2nd O RunddichtringO 7 to seal between piston cap 4 and the piston rod 3, has the 3rd O RunddichtringO 11 to seal between piston cap 4 and the clamping body 1;
Have oil-in on the piston cap 4, hydraulic oil gets in the piston cylinder through oil-in.
Said both sides piston rod 3 adopts same hydraulic power source to pressurize, and avoids the appearance of additional side force.
The quantity of said clamp 2 can increase and decrease according to the size of required clamping force.
On the said piston rod 3 spring is housed, for the automatic resilience of piston rod provides screen resilience.
Said clamping body 1 can be selected with the shape of guide rail, realizes the clamping of line slideway or arc guide rail.
The operation principle of the utility model and the course of work:
After movable body puts in place with the way block motion; Hydraulic oil gets in the plunger shaft through both sides oil circuit 12, promotes 3 motions of clamper both sides piston rod, drives clamp 2 and clamps guide rail; Realization is to the clamping of guide rail; Reduced the load of drive disk assembly, reduced the influence of transmission accuracy, ensured the machining accuracy of lathe machining accuracy.
The motion of piston rod 3; Compressed the spring 5 that is contained on the piston rod 3, when the relative guide rail movement of needs movable body, the hydraulic oil pressure release; Piston rod 3 is got back to the origin-location under the effect of spring 5 screen resiliences; Piston rod 3 drives clamp 2 motions simultaneously, and the chucking power disappearance to guide rail realizes the freely-movable of movable body.
