Core-assembly mechanical device with self-adaptive positioning function

Abstract

The invention discloses a core-assembly mechanical device with a self-adaptive positioning function. The core-assembly mechanical device comprises a cross beam. A transverse linear guide rail is arranged on the cross beam; a double-output-shaft servo motor sliding block sliding along the linear guide rail is arranged on the linear guide rail; a double-output-shaft servo motor is connected to the double-output-shaft servo motor sliding block; two output shafts of the double-output-shaft servo motor are connected with a left screw rod and a right screw rod correspondingly, wherein the thread directions of the left screw rod and the right screw rod are opposite, and the left screw rod and the right screw rod are parallel to the linear guide rail; the left screw rod and the right screw rod aresleeved with screw rod nuts correspondingly; the screw rod nuts are connected with mechanical arms; and clamps used for clamping a sand core are connected to the mechanical arms. The core-assembly mechanical device with the self-adaptive positioning function is simple and compact in structure; the sand core can be automatically adjusted in position under the effect of the positioning inclined planes of core-assembly table positioning blocks, and damage to the sand core is effectively avoided; and the sand core can be well placed at a time, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical clamping devices, in particular to an self-adaptive positioning core assembly mechanical device. Background technique [0002] With the development of the casting process, a new core assembly process has emerged, which is to place the prepared sheet-shaped sand cores on the core assembly table in an upright manner, and then drive the core assembly table to make the two sand cores close to each other. Together, the two sand cores are then fixed with bolts, so that the assembly of the sand cores is completed in a layered superimposition of one piece close to the other. However, it is difficult to accurately place the chips of the sand core on the core assembly table. The chips placed on the sand core by driving are prone to swinging back and forth, which is difficult to locate and the assembly efficiency is low; The direct collision of the positioning block on the table will easily damage the sa...
