Description
Technical Field
The utility model relates to a frock clamp technical field specifically is a thin wall shell processing location presss from both sides tight structure.
Background
As shown in fig. 1, in the process of machining a thin-walled shell workpiece, because the wall of the workpiece is thin, when a traditional hydraulic fixture is used for machining, four corners of the workpiece are difficult to clamp and fix, so that the supporting force around the four corners of the workpiece is insufficient, a tool is easy to vibrate, the service life of the tool is affected, the machining precision of the hole diameter of the workpiece is also easy to affect, the precision requirement of the workpiece cannot be met, and the machining efficiency is low.
SUMMERY OF THE UTILITY MODEL
When adding man-hour to current thin wall casing class work piece, traditional hydraulically operated fixture can't press from both sides the fastening with its four bights and fix, leads to shaking the sword and influence the problem of machining precision, the utility model provides a thin wall casing processing location presss from both sides tight structure, and it can be fixed with four bight departments clamp of thin wall casing tightly, and the clamping is effectual, has effectively reduced to shake the sword unusually, has improved machining precision and efficiency.
The technical scheme is as follows: the utility model provides a thin wall casing processing location presss from both sides tight structure, its includes the base, be equipped with the material platform of putting of placing the work piece on the base, its characterized in that: be located put the bight position department of the long avris of material platform is equipped with the pneumatic cylinder respectively, the piston rod and the articulated connection of clamp plate one end of pneumatic cylinder, the middle part of clamp plate is rotated through pivot and connecting plate one end and is connected, the other end of connecting plate through the pivot with install in fixed block on the base of pneumatic cylinder rotates and is connected, wherein the middle part position department of the long avris of material platform is put to one side still is equipped with the tight cylinder in top, is located put the short avris of material platform and also be equipped with the tight cylinder in relative top respectively, the tight cylinder in top install in through the mount pad respectively on the base.
It is further characterized in that: the long side edge of one side of the jacking cylinder, which is far away from the material placing table, is provided with a positioning key, and two ends of the positioning key are provided with positioning pins.
After having adopted above-mentioned structure, place the work piece and put the material bench, the pneumatic cylinder that sets up through its long avris bight department drives the clamp plate and fixes four angles portions pressure tight of work piece, and the tight cylinder in rethread top is tight to the outside three-point top of work piece, effectively guarantees that this thin wall work piece presss from both sides tightly fixedly, and the clamping is effectual, has effectively reduced the sword anomaly that shakes, has improved machining precision and efficiency.

Detailed Description
As shown in fig. 2 to 4, a thin-wall housing processing, positioning and clamping structure comprises a base 1, an oil separator 10 is arranged outside the base 1, a material placing table 2 for placing a workpiece is arranged on the surface of the base 1, hydraulic cylinders 3 are respectively arranged at the corner positions of the long side of the material placing table 2, the bottoms of the hydraulic cylinders 3 are installed on the base 1, piston rods of the hydraulic cylinders 3 are hinged to one end of a pressing plate 4, the middle of the pressing plate 4 is rotatably connected with one end of a connecting plate 5 through a rotating shaft, the other end of the connecting plate 5 is rotatably connected with fixing blocks installed on the base of the hydraulic cylinders 3 through a rotating shaft, four corners of the workpiece can be pressed by the four hydraulic cylinders 3 respectively arranged at the corner positions of the material placing table 2, the clamping effect is good, meanwhile, a jacking cylinder 6 is also arranged at the middle position of the long side of the material placing table 2 at one side, opposite jacking cylinders 6 are also respectively arranged at the short side of the material placing table 2, the jacking cylinders 6 are respectively installed on the base 1 through installing seats, three jacking cylinders 6 which are evenly distributed can jack three edges of the workpiece tightly, and further fix the workpiece.
Furthermore, the edge of the long side far away from one side of the jacking cylinder 6 on the material placing table 2 is provided with a positioning key 7, and the two sides of the positioning key 6 are also provided with positioning pins 8 connected with the base 1.
The utility model discloses a theory of operation as follows:
the workpiece is placed on the material placing table 2, and the degree of freedom of the workpiece is limited and the positioning stability of the workpiece is ensured by the arrangement of the positioning key 6 and the positioning pin 8; because the requirement on the machining precision of the square hole of the workpiece is high, in order to prevent the size from being out of tolerance caused by unstable pressing force, four corners of the workpiece are pressed through four hydraulic bars 3 and electric pressing plates 4 arranged on the outer side of a material placing table 2, the warping of the workpiece is effectively prevented, three pressing points are uniformly distributed through three pressing cylinders 6 outside the material placing table 2, the outer end sides of three edges of the workpiece are assisted to be pressed, the vibration of the part is effectively prevented, the clamping force is adjustable and stable, and the part is prevented from deforming.
The above description is only for the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
