Description
Technical field
The utility model relates to the Precision Machining field of aerospace system, relates in particular to a kind of clamping device of sheet part.
Background technology
Along with science and technology development, in light weight, thin thickness and the big sheet part of area more and more are widely used in all trades and professions, especially the Space Science and Technology field.But,, thereby cause relatively difficulty of processing sheet part because sheet part itself is relatively thinner and material most of part is again an aluminium sheet.
At present, the clamping method of the routine of sheet part processing is a pressure plate on four limits of sheet part, thereby realizes the clamping of sheet part.Yet; Because the sheet part area is bigger; Cutting force that produces in the mechanical processing process and heat in metal cutting can make the mid portion of sheet part produce vibration, thereby, be difficult to guarantee the applying of sheet part mid portion and locating surface; Thereby sheet part can produce bigger distortion, does not reach the requirement of flatness.
To the installation way of above-mentioned routine, the someone has invented a kind of improved clamping method.This method is that sheet part is put between two block pressur plates, and the periphery of two block pressur plates is fixed with trip bolt again.Yet because pressing plate is to lean on the trip bolt of periphery to screw, the sheet part mid portion needs processing; Can not compress; When clamping, be difficult to fully entirely be fixed in the pressing plate, thereby, add man-hour; The revolving force that makes progress that process tool produces makes sheet part be distorted easily, thereby produces distortion.
Therefore, be necessary to provide a kind of clamping device of sheet part to overcome above-mentioned defective.
The utility model content
The purpose of the utility model provides a kind of clamping device of sheet part, can not only guarantee sheet part in process planarization and with the fitting tightly of locating surface, and simple in structure, easy to operate, cost is low.
To achieve these goals; The utility model provides a kind of clamping device of sheet part; Comprise the slip location-plate and the push rod of installing plate, placement sheet part, the activity of slip location-plate is fixed on the installing plate, vertically offers first through hole that runs through installing plate and be positioned at slip location-plate below on the installing plate; One end of push rod passes first through hole, and the other end of push rod is fastened in first through hole.
In an embodiment of the utility model, installing plate has cavity, and the slip location-plate is placed in the cavity of installing plate, and first through hole of installing plate and the cavity of installing plate connect.
Preferably, first through hole is stepped, and the longitudinal cross-section of push rod is " T " font.
In another embodiment of the utility model; The clamping device of sheet part also comprises positioning pillars; Vertically offer second through hole on the slip location-plate; Vertically also offer on the installing plate and third through-hole that second through hole of the location-plate that slides connects, second through hole that positioning pillars is passed the slip location-plate is fastened in the third through-hole of installing plate.
Preferably, second through hole and third through-hole are all stepped.
Preferably, positioning pillars comprises successively first cylinder, second cylinder and the three cylindrical that connects, and the diameter of said second cylinder is greater than the diameter of three cylindrical and less than the diameter of first cylinder.
Compared with prior art; Because the contact area of the sheet part of the utility model and slip location-plate is greatly and can fit fully, thereby, during the sheet part clamping; The clamping stress that needs is very little; The clamping state is stressed uniform and stable, thereby has overcome the influence to sheet part of the rotary cutting power that adds the cutter in man-hour and heat in metal cutting, and then guarantees the flatness of thin plate effectively.In addition, the manufacturing of the utility model, maintenance cost is low and easy to operate.
Through following description and combine accompanying drawing, it is more clear that the utility model will become, and these accompanying drawings are used to explain the embodiment of the utility model.
