A fixture for correcting the shape of the lower cover of the heater

Abstract

The invention discloses a correcting clamp for a heater lower cover, which belongs to the technical field of correcting clamps. The correcting clamp comprises a mounting base, wherein the top of the mounting base is connected with a mounting plate through a rotary assembly; a fixed plate and a movable plate are separately arranged at the left end and the right end of the top of the mounting plate;the right side of the movable plate is connected with the output end of a telescopic air cylinder; the tops of clamping assemblies are fixedly equipped with spherical rods; a movable ball base sleeves each spherical rod; the side wall of each movable ball base is connected with a connecting rod; and the top of each connecting rod penetrates through a regulating bolt. According to the correcting clamp disclosed by the invention, clamping spacing between two groups of clamping assemblies is regulated through the telescopic air cylinder, and clamping plates on the clamping assemblies are utilized for clamping the heater lower cover; and meanwhile, the clamping assemblies adopt rotatable designs, so that the heater lower cover is prevented from generating deformation as a result of too greatclamping force, and therefore, the correcting effect is realized on the heater lower cover. The correcting clamp is reasonable in design, is simple to operate, and is wide in range of application.

Description

technical field [0001] The invention discloses a shape correcting jig for a lower cover of a heater, in particular to the technical field of shape correcting fixtures. Background technique [0002] Heaters can be seen everywhere in life, and the most common heating device should be electric cooking utensils, such as electric rice cooker, electric baking pan, induction cooker, etc. In the production process of these cooking utensils, the production of the lower cover of the electric heater is also particularly important. In the production process of the lower cover of the heater, it is generally necessary to further correct the shape after spinning by the spinning machine, and the lower covers of these heaters are generally arc-shaped, which makes it particularly difficult to fix the lower cover in the process of correcting the shape. Importantly, the traditional shape-calibrating fixture generally uses the fixture to directly clamp along the rim of the lower cover, which not...

In the production process of the lower cover of the heater, it is generally necessary to further correct the shape after spinning by the spinning machine, and the lower covers of these heaters are generally arc-shaped, which makes it particularly difficult to fix the lower cover in the process of correcting the shape. Importantly, the traditional shape-calibrating fixture generally uses the fixture to clamp directly along the rim of the lower cover, which not only easily deforms the lower cover, but also tends to loosen, while the clamp that clamps the center of the lower cover is often prone to rotation
