Description

Technical Field

[0001] The utility model relates to the technical field of salt bath heat treatment, in particular to a clamping device capable of preventing samples from being clamped. Background Art

[0002] Salt bath heating is a heat treatment method that uses molten salt to heat and quench the workpiece. Compared with traditional air medium furnace heating, salt bath heating not only has the advantages of fast heating speed, good quality, and less decarburization and oxidation loss, but also can effectively reduce the deformation of the workpiece during the heat treatment process. These advantages make salt bath heating widely used in many industrial applications, especially in the treatment of workpieces with high requirements for heat treatment quality. It is of great significance.

[0003] According to a disclosed device for heat treatment of precision parts in a salt bath (publication number: CN219730990U), the above application includes a base, a quenching box, a fixing frame, a motor, a first gear, a second gear, a rotating rod and a mounting frame. The motor drives the second gear through the first gear, thereby driving the rotating rod and the mounting frame to rotate. The rotation of the mounting frame causes the precision parts to rotate and shake accordingly, so that the fitting parts between the precision parts are separated, allowing the salt bath to cover various parts of the precision parts. The rotation of the precision parts also impacts the salt bath, causing the salt bath to flow into the gaps of the precision parts.

[0004] However, during actual use of the above-mentioned processing device, the rotation of the mounting frame can drive the bearing to rotate together. During the rotation, the bearings will shake and separate from each other during the shaking. However, this shaking will also cause the bearings to collide with each other, which may cause damage. Since the bearings may be subjected to uneven forces during rotation and shaking, these forces may cause scratches, dents or more serious structural damage to the bearing surface. In view of this, we propose a clamping device that can prevent sample clamping. Utility Model Content
