Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, are merely for convenience of description of the present invention, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

Referring to fig. 1 to 4, the heating positioning furnace comprises a heating positioning furnace 1 and two fixture fixing devices 2, the two fixture fixing devices are distributed on two sides of the heating positioning furnace 1, the two fixture fixing devices 2 are arranged along a same horizontal straight line, the two fixture fixing devices 2 have the same structure, each fixture fixing device 2 comprises a bearing containing cylinder 3, a fixed supporting part 4 and a bearing limiting part 5, the fixed supporting part 4 is arranged at the bottom of the bearing containing cylinder 3, the bearing limiting part 5 is arranged in the bearing containing cylinder 3, the two fixture fixing devices 2 can realize the locking and positioning operation of a material to be processed, as each fixture fixing device 2 positions the material to be processed by the locking force of the fixture fixing device, the material to be processed can be limited and locked in the direction perpendicular to the axis of the bearing containing cylinder 3, the material to be tested is prevented from being damaged due to the fixing of the material to be tested by the locking force of the clamp.
