Mirror polishing clamp for hardware middle frame

Abstract

The invention discloses a mirror polishing clamp for a hardware middle frame. The clamp structurally comprises a mounting frame, a pushing block, a supporting bottom plate and a clamping mechanism, wherein the top of the mounting frame is welded to the bottom surface of the supporting bottom plate, the clamping mechanism is fixedly installed in the upper end of the supporting bottom plate in an embedded mode, and a pushing rod drives a movable clamping piece to move. A gap between an arc surface of the movable clamping piece and an attaching face of the outer side end of a flat plate middle frame is reduced, and an air bag film is bulged to conduct abutting protection on the outer side end of the flat plate middle frame, so that protection is achieved while the clamping firmness of the outer side of the flat plate middle frame is improved. Through torsion rotation of a torsion shaft, the connecting rod rotates in an arc mode around the circle center end of the torsion shaft. The abutting rod abuts against the inner side end of the flat plate middle frame, the friction force generated when the rubber strip abuts against the interior of the flat plate middle frame is increased through extrusion of a jacking spring, so that it is ensured that a clamping force is applied to the inner side end of the flat plate middle frame, and the flat plate middle frame is prevented from deviating in the polishing process.

Description

technical field [0001] The invention relates to the field of surface polishing processing in hardware production, and more specifically, relates to a jig for mirror surface polishing processing of a metal middle frame. Background technique [0002] A tablet computer is also called a portable computer, which is a small, portable personal computer. The middle frame outside the tablet computer is a frame for protecting the tablet computer. During the processing of the middle frame, a mirror polishing machine is required to fix it. For polishing, the fixture on the polishing machine clamps it to ensure the normal polishing of the middle frame. However, because the thickness of the middle frame of the flat plate is relatively thin, and the four sides of the middle frame of the flat plate are all arc-shaped structures, the clamping During the process, the bonding piece on the fixture is relatively flat, which is easy to be over-extruded, resulting in deformation of the arc surface...

[0002] A tablet computer is also called a portable computer, which is a small, portable personal computer. The middle frame outside the tablet computer is a frame for protecting the tablet computer. During the processing of the middle frame, a mirror polishing machine is required to fix it. For polishing, the fixture on the polishing machine clamps it to ensure the normal polishing of the middle frame. However, because the thickness of the middle frame of the flat plate is relatively thin, and the four sides of the middle frame of the flat plate are all arc-shaped structures, the clamping During the process, the bonding piece on the fixture is relatively flat, which is easy to be over-extruded, resulting in deformation of the arc surface of the flat middle frame. At the same time, there is a certain gap between the flat fixture and the arc surface of the middle frame. The gap, which reduces the fit of the middle frame for clamping, reduces the firmness of the middle frame during the polishing process
