The machine tool positioning and clamping structure is characterized in that the oil cylinder component comprises a cylinder body fixedly arranged on the slide plate located on the other side of the hinge screws, a piston and a piston rod are arranged inside the cylinder body, the piston rod is contacted with the pressing plate, a hydraulic pressure oil circuit is arranged on the cylinder body located on one side of the piston rod, the hydraulic pressure oil circuit is communicated with a cavity with a rod of the cylinder body, and a clamping spring is arranged on a cavity without a rod of the bottom of the piston. The machine tool positioning and clamping structure has the advantages of being stable in clamping force, high in positional accuracy and low in energy consumption.
Description
Technical field
The utility model relates to a kind of locating clip locking structure that is used for lathe.
Background technology
In the boring-mill work that high precision machine tool or heavily loaded stock-removing machine position, need not carry out three-shaft linkage, at this moment motionless axle need clamp to improve positioning accuracy and the lathe rigidity that adds man-hour, and the current clip locking structure mainly is with hinge screws pressing plate to be linked to each other with slide plate; Utilize lever principle with oil cylinder to the pressing plate application of force; Clamp the hold-down plate surface of guide rail, realize that the location of lathe clamps, the clamping of lathe location needs the hydraulic jack continuous firing; Its clamping force can change because of pressure fluctuation; Positioning accuracy is difficult to guarantee that the start-up time of Hydraulic Station while is longer, and energy consumption is higher.
The utility model content
The purpose of the utility model is the above-mentioned deficiency to prior art, and a kind of lathe locating clip locking structure is provided, and it has the advantage that clamping force is stable, positioning accuracy is high, energy consumption is lower.
For achieving the above object; The lathe locating clip locking structure of the utility model comprises the slide plate that is loaded on the lathe bed, the bed ways that cooperate with slide plate slides, is loaded on the pressing plate on the slide plate and is loaded on the cylinder component on the slide plate through hinge screws, and an end of pressing plate contacts with bed ways; It is characterized in that said cylinder component comprises the cylinder body that is installed on the hinge screws opposite side slide plate; In cylinder body, be provided with piston and piston rod, piston rod contacts with pressing plate, on the cylinder body of piston rod one side, is provided with hydraulic circuit; Hydraulic circuit communicates with the rod chamber of cylinder body, in the rodless cavity of piston base, is provided with fastening spring.
When bed ways need move, the hydraulic circuit oil-feed of the utility model, piston rod is retreated, and hydraulic oil promotion piston overcomes fastening spring power and unclamps the clamping guide rail; When the hydraulic circuit release, it is overhanging that fastening spring promotes piston rod, and pressing plate is that rotate at the center with the hinge screws, utilizes the regulations and parameters principle to amplify and imposes on pressing plate, clamps bed ways, plays the purpose that the location clamps; The utility model relies on the elastic force of fastening spring when clamping in the location, have the advantage that pressure is stable, positioning accuracy is high, and reduced the start-up time of Hydraulic Station, and energy consumption is lower;
Further improvement as the utility model also is provided with the adjustment screw through locking nut on pressing plate, the adjustment screw is corresponding with the position of piston rod; Through the position of the adjustment screw that changes, the pressure of adjusting piston pole pair pressing plate;
As the further improvement of the utility model, said fastening spring is a butterfly spring; Butterfly spring has the bigger coefficient of stiffiness, can improve pressure to greatest extent;
As the further improvement of the utility model, the end that said pressing plate contacts with bed ways also be provided with laminating; Can protect the surface of bed ways;
In sum, the utlity model has the advantage that clamping force is stable, positioning accuracy is high, energy consumption is lower, and clamping force is convenient to adjustment.
Description of drawings
Fig. 1 is the front view of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
By shown in Figure 1; This lathe locating clip locking structure, is loaded on the pressing plate 4 on the slide plate 1 and is loaded on the cylinder component on the slide plate 1 through hinge screws 3 at the bed ways 2 that comprise the slide plate 1 that is loaded on the lathe bed, are slidingly matched with slide plate 1, and the pressing plate end 4a of hinge screws 3 one sides contacts with bed ways 2; And on the 4a of this pressing plate end, be installed with laminating 12; Said cylinder component comprises the cylinder body 5 that is installed on the hinge screws 3 opposite side slide plates, in cylinder body 5, is provided with piston 6 and piston rod 7, and piston rod 7 contacts with pressing plate 4; On pressing plate 4, also be provided with adjustment screw 9 through locking nut 8, adjustment screw 9 is corresponding with the position of piston rod 7; On the cylinder body of piston rod 7 one sides, be provided with hydraulic circuit 10, hydraulic circuit 10 communicates with the rod chamber of cylinder body 5, in the rodless cavity of piston base, is provided with to clamp butterfly spring 11;
During hydraulic circuit 10 oil-feeds of the utility model, piston rod 7 is retreated, and pressing plate 4 is in free state, and pressing plate 4 unclamps bed ways 2; When hydraulic circuit 10 releases, it is overhanging to clamp butterfly spring 11 promotion piston rods 7, holds out against pressing plate 4, and pressing plate 4 is that rotate at the center with hinge screws 3, and the pressing plate end 4a of a side compresses bed ways 2, plays the purpose that the location clamps; The utility model relies on the elastic force that clamps butterfly spring 11 when clamping in the location, has the advantage that pressure is stable, positioning accuracy is high, and has reduced the start-up time of Hydraulic Station, and energy consumption is lower; Through the position of the adjustment screw 9 that changes, the pressure of 7 pairs of pressing plates 4 of adjusting piston bar; Utilize the range difference of hinge screws 3, also can play lever augmented effect to piston rod stress point and pressing plate clamping point.
