Parallel fork clamp

Abstract

The invention belongs to the field of heat machining auxiliary tools, and discloses a parallel fork clamp. The fork clamp comprises two fork clamp bodies and two crossing rods; the two fork clamp bodies are arranged side by side in the same direction, a telescopic handle is arranged at one end of each fork clamp body, a fork clamp rod is arranged at the other end of each fork clamp body, the telescopic handles and the fork clamp rods are located on the same straight line, a hinge head is arranged at one end of each telescopic handle, a hinge base is arranged between each telescopic handle and the corresponding fork clamp rod, the middles of the two crossing rods are connected, one ends of the crossing rods are hinged to one hinge head, and the other ends of the two crossing rods are hinged to one hinge base. According to the fork clamp, a clamped object is not prone to inclining and slipping.

Description

technical field [0001] The invention belongs to the field of thermal processing auxiliary tools, in particular to a parallel fork pliers. Background technique [0002] At present, when using a large-scale heating furnace or a heating box to heat workpieces or trial products, trays or brackets are mostly used to hold the workpieces or trial products. When heating the furnace or heating box, especially when the workpiece or trial product needs to be taken out of the heating furnace or heating box after the heating is completed, because the tray or bracket often has a high residual temperature, the staff cannot directly use it to prevent burns. When the hand touches the tray or bracket, it is necessary to use clamps to hold the tray or bracket and take it out. However, when the existing clamps clamp the tray or bracket, the contact area between the jaws and the tray is not enough and cannot be stable. Clamp the pallet or bracket carefully, especially when the workpiece or tria...

[0002] At present, when using a large-scale heating furnace or a heating box to heat workpieces or trial products, trays or brackets are mostly used to hold the workpieces or trial products. When heating the furnace or heating box, especially when the workpiece or trial product needs to be taken out of the heating furnace or heating box after the heating is completed, because the tray or bracket often has a high residual temperature, the staff cannot directly use it to prevent burns. When the hand touches the tray or bracket, it is necessary to use clamps to hold the tray or bracket and take it out. However, when the existing clamps clamp the tray or bracket, the contact area between the jaws and the tray is not enough and cannot be stable. Clamp the pallet or bracket carefully, especially when the workpiece or trial product on the pallet or bracket is heavy, it is easy to cause accidents such as tilting and sliding of the pallet or bracket during the removal process, resulting in damage to the workpiece or trial product
