Device for compensating for deflection in automatic locking systems

Abstract

A device (1) for compensating deflection in an automatic locking system of a mounting blank (2) provided with a first hole (3) for a fixing element (4), in the At the end there is a first seat (6) for centering the bush (7) and the device consists of a box-like body (10) consisting of a T-shaped hollow body (11) and a U-shaped base (12) consisting of a base part forming an inner seat part (13) for a frustum-shaped cover (14) arranged coaxially with the shank (15) of the hollow body (11) and arranged on the piston (16), the piston can be moved laterally to the handle (15), the traction element (40) is slidably arranged in the handle (15) of the hollow body (11) and formed axially with the fixed element (4) In one piece, a centering bush (7) is associated in and coaxially with the upper region and can be arranged at a first seat (6) having a Larger in diameter than the fixed first hole (3) and arranged eccentrically with respect to this first hole, the traction element (40) selectively cooperates with a ball (31) which can be accommodated in an adapted opening (29) Inside and adapted second seat (33), the opening is provided in the handle (15), the second seat is provided on the cover (14), the elastically compressible element (36) is arranged in the hollow body ( Between the head (21) of 11) and the cover (14), means are provided which allow the piston to move axially temporarily.

Description

technical field [0001] The present application relates to a device for compensating for offsets in automatic locking systems for mounting blanks (blanks, blanks). Background technique [0002] Now European patent EP1346794B1 is known, which relates to a modular structure specifically for mounting blanks on holders, which solves the need to lock the workpiece and / or blank in a predetermined position for carrying out Problems with certain operations of handling, such as painting, cleaning, and assembly, or many different forms of machining, such as removing shavings. [0003] Thus, devices are known which are indispensable (but not necessarily in a purely industrial environment) whenever objects handled in a general and even simple manner require a stable locking. [0004] A significant disadvantage complained of in conventional devices lies in the fact that, in order to achieve a stable locking of a workpiece, it is necessary to bring both spaced apart elements of the lockin...

Problems solved by technology

[0013] Although this solution solves the above-mentioned problems, this solution also has the disadvantage that it has been found that in the part to be fixed and thus in the blank (designated 50 in the EP1346794B1 patent) there is obtained for the fixing element ( Such as a threaded shank, designated 39a in EP1346794B1) with a first threaded hole (designated 36 in EP1346794B1) and thus a first seat for a centering bush (designated 37 in EP1346794B1) Part (designated 34 in the EP1346794B1 patent): During the production of the part to be fixed, some machining steps cause changes in the geometry of the workpiece, since the first seat may subsequently be re-centered with a larger size and the The first seat may then be in the best position for centering of the part (slightly offset from the previous position)
