Abstract
The utility model discloses a centring means convenient to unloading in automation, including being used for the suit and fixing a position bracket, the pressure disk of work piece and set up in the bracket top and press the gland on the pressure disk with the work piece, the pressure disk suit is fixed on the bracket and through the fastener, be equipped with the telescopic ejecting device who is used for ejecting work piece between bracket and pressure disk, ejecting device when compression highly be not higher than the pressure disk up end, these anchor clamps simple structure, economical and practical satisfies unloading on the manipulator, is fit for automatic production line and goes up and require not high equipment to the work piece location.
Description
Technical field
The utility model belongs to fixture field, is specifically related to a kind of centering unit being convenient to automatic loading/unloading.
Background technology
In Gear Processing automatic production line, mechanical manipulator is had to need directly to carry out loading and unloading action on lathe fixture, automatic production line loading and unloading manipulator walking repetitive positioning accuracy is generally 0.2mm, within hole orientate example as, 0.2mm need to be greater than in the gap of reload state lower clamp mandrel and inner hole of workpiece and could meet mechanical manipulator and carry out normal loading and unloading.
Traditional swollen amount of mechanical expansion chuck tool is little, and the gap between inner hole of workpiece is generally less than 0.2mm, therefore the insecure problem of mechanical manipulator loading and unloading is easily caused, now with way be on the table be equipped with a drawing cylinder, though the method expands gap value to a certain extent, but the centering requirement of workpiece can not be met.
Summary of the invention
In view of this, the purpose of this utility model be to provide a kind of structure simple, the reliable loading and unloading of mechanical manipulator can be met, the fixture device can felt relieved again.
For achieving the above object, the utility model provides following technical scheme: a kind of centering unit being convenient to automatic loading/unloading, comprise bracket, the pressure dish for being set with also positioning workpieces and it is arranged on the gland being pressed against on pressure dish above bracket and by workpiece, described pressure dish is sleeved on bracket and is fixed by fastening piece, being provided with the telescopic liftout attachment for ejecting workpiece between described bracket and pressure dish, height when described liftout attachment compresses is not higher than pressure dish upper surface.
Further, described bracket is convex structure, comprises the location axle of top and the installation boss of lower section, and described installation boss is provided with blind hole, and on described pressure dish, correspondence is provided with through hole.
Further, described liftout attachment comprises spring and push rod, and described spring is arranged in the blind hole on bracket, and described push rod is arranged on above spring and passes the through hole on pressure dish.
Further, described location axle is provided with the positioning section of some sections of different diameters from small to large, is provided with guiding angle between adjacent two sections.
The beneficial effects of the utility model are: this clamp structure is simple, economical and practical, easy to operate, meets mechanical manipulator loading and unloading requirement, can realize rapidly workpiece centering, especially be applicable on automation line the less demanding equipment of Workpiece fixing.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and useful effect clearly, the utility model provides following accompanying drawing to be described:
Fig. 1 is structural representation of the present utility model (loading and unloading state);
Fig. 2 is the working state schematic representation of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in the figure, centering unit in the present embodiment, comprise bracket 2, the pressure dish 3 for being set with also positioning workpieces 1 and it is arranged on the gland 4 being pressed against on pressure dish 3 above bracket 2 and by workpiece 1, described pressure dish 3 is sleeved on bracket 2 and is fixed by fastening piece, being provided with the telescopic liftout attachment for ejecting workpiece 1 between described bracket 2 and pressure dish 3, height when described liftout attachment compresses is not higher than pressure dish 3 upper surface.
Bracket 2 in the present embodiment is convex structure, comprises the location axle 21 of top and the installation boss 22 of lower section, and described pressure dish 3 is sleeved on location axle 21 outside of bracket 2 and fixes with installation boss 22. Described installation boss 22 is provided with blind hole, and on described pressure dish 3, correspondence is provided with through hole.
Concrete, the liftout attachment in the present embodiment comprises spring 5 and push rod 6, and described spring 5 is arranged in the blind hole on bracket 2, and described push rod 6 is arranged on above spring 5 and passes the through hole on pressure dish 3.
As the further improvement of such scheme, described location axle 21 is provided with the positioning section of some sections of different diameters from small to large, is provided with guiding angle between adjacent two sections.
This device can meet the reliable loading and unloading of mechanical manipulator, can feel relieved again. The lower end of device is arranged on the table 7, combines by bracket 2, spring 5, push rod 6 and pressure dish 3, and push rod 6 can slide up and down, and push rod 6 anchorage force is greater than workpiece 1 gravity. Upper and lower two sections of 21 points, axle located by bracket 2, upper section external diameter 1mm less of hole in workpiece 1, hypomere external diameter 0.03mm less of hole in workpiece 1 (can adjust according to practical situation), arranges guiding angle between upper and lower two sections. When waiting mechanical manipulator loading and unloading state, gland 4 is mentioned, and workpiece 1 is held up by push rod 6, and workpiece 1 lower surface departs from pressure dish 3, and now in workpiece 1, hole and bracket gap are 1mm, and mechanical manipulator can carry out loading and unloading action; After until machinery, blanking completes on hand, gland 4 moves downward, and pressured lid 4 pressure is by workpiece 1 to pressing down, until workpiece 1 lower surface touches pressure dish 3, now, in workpiece 1, hole and bracket gap are 0.03mm, namely realize workpiece 1 and feel relieved.
What finally illustrate is, above preferred embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although the utility model being described in detail by above preferred embodiment, but those skilled in the art are to be understood that, in the form and details it can be made various change, and do not deviate the utility model claim book limited range.
