Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work property, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model clamping device preferred embodiment.
The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
With reference to Fig. 1, Fig. 1 is the structural representation of the utility model clamping device preferred embodiment, comprises lever assembly and latch assembly.
In this embodiment lever assembly, comprise oil cylinder 9, connector 11, compact heap 5 and adjusting pad 13; Connector 11 is connected with the piston rod 8 of oil cylinder 9; Wherein, adjusting pad 13 is arranged between the upper surface of lower surface 112 and lathe crossbeam 10 of connector 11, and is fixedly connected with lathe crossbeam 10.Connector 11 comprises first surface 111 and second surface 112; The lower surface of compact heap 5 rolls with first surface 111 and is connected; Second surface 112 rolls with the upper surface of adjusting pad 13 and is connected; The lower surface of compact heap 5 is the inclined-plane; Compact heap 5 is through column 1 clamping and positioning of latch assembly and lathe.
Specifically, the connected mode between connector 11 and compact heap 5 and the adjusting pad 13 is specially: first surface 111 is provided with first roller 7, and the lower surface of compact heap 5 rolls with first surface 111 through first roller 7 and is connected.Second surface 112 is provided with second roller 12, and second surface 112 rolls with the upper surface of adjusting pad 13 through second roller 12 and is connected.When specific embodiment, as shown in Figure 1, can be provided with one first roller 7 at first surface 111; Simultaneously, can be provided with two second rollers 12 at second surface 112.Present embodiment is owing to adopt roller, and rolling friction diminishes with respect to sliding friction greatly, thus, greatly reduces the oil cylinder pulling force and is used for fricative component, has reduced oil cylinder working-pressure, improved the stability of oil cylinder.In addition, adjusting pad 13 effects that are provided with in the lever assembly have two, one, the height of adjustment oil cylinder and roller connector, and the 2nd, because long-time the use, the strong in the above load running of roller can produce distortion, is convenient to change.
And among this embodiment, latch assembly can comprise bolt 6, first alignment pin 4, second alignment pin 14 and axle bed 3; Bolt 6 is fixed in crossbeam 10 with compact heap 5 and axle bed 3; First alignment pin 4 and second alignment pin 14 are fixed in the compact heap 5 of bolt 6 both sides.That is to say that this embodiment adopts two alignment pins (first alignment pin and second alignment pin) to be fixed on the compact heap 5 of bolt 6 both sides, prevents that compact heap 5 from rotating when crossbeam 10 moves, and influences positioning accuracy.And bolster 2 is installed in the axle bed 3, and when the crossbeam that guarantees 10 moved, the smooth sliding of bolster 2 had improved the stability that clamps greatly.
The operation principle of present embodiment is following:
To sum up, the utility model embodiment clamping device is connected connector with the piston rod of oil cylinder, and in the top and bottom of connector interactive slide mechanism or rolling mechanism is set respectively, through lever principle compact heap column guide pass is locked.Therefore, the utility model is simple and compact for structure, clamping is reliable and stable, easy operating, safety, nothing are revealed, economical and practical.
In addition, about this embodiment, following 2 needs explanation is arranged:
The first, the lower surface of compact heap 5 and first surface 111 also can adopt and be slidingly connected; The upper surface of second surface 112 and adjusting pad 13 equally also can adopt and be slidingly connected.Basis is practical does not do qualification at this.This embodiment adopts to roll and connects, for no other reason than that force of rolling friction is far smaller than force of sliding friction, adopts rolling friction can lower the oil cylinder pulling force like this and is used for fricative pulling force, and then reduce pressure, improves the stability of oil cylinder.That is to say that rolling is connected to preferably, but the utility model is not got rid of the connected mode of slip.And the quantity of the utility model pair roller is not done qualification yet.
The second, the utility model also can not be provided with adjusting pad 13, that is, the lower surface of compact heap 5 is slidingly connected or rolls with first surface 111 and is connected; Second surface 112 is connected or the connection of rolling with the slide of lathe crossbeam 10.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
