Description

Technical Field

[0001] This utility model relates to the field of tensioning fixture technology, and in particular to a plate-type tensioning fixture. Background Technology

[0002] A jig is a device used in the machining and manufacturing process to fix the workpiece in the correct position so that it can be processed.

[0003] Existing methods for dip coating of metal workpieces generally use press-type fixtures, which clamp and position the metal workpieces by applying pressure. The force applied during clamping is relatively large and can easily cause workpiece deformation. This method is not suitable for thin-walled, easily deformable, or complex metal workpieces, nor can it be adapted to clamping workpieces of different diameters. Furthermore, the clamping process is time-consuming and labor-intensive, making it difficult to complete the clamping operation quickly and achieve continuous automatic operation.

[0004] How to develop a plate-type tensioning fixture that uses tension to fix metal workpieces, completes the positioning operation of metal workpieces of different diameters during the clamping process, and facilitates quick clamping has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a plate-type tensioning fixture to solve the problems listed in the background art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model relates to a plate-type tensioning fixture, which includes a fixed base, and the fixed base is slidably connected to the tensioning assembly. The fixing base includes a fixing base body, a V-shaped groove is formed on one side wall of the fixing base body, a first circular through groove is formed at one end of the V-shaped groove, and a rectangular through groove is formed at the other end of the V-shaped groove. The tensioning assembly includes a tensioning plate unit and an elastic reset unit. The tensioning plate unit is slidably connected to the rectangular through groove. One end of the elastic reset unit abuts against the tensioning plate unit, and the other end of the elastic reset unit abuts against the opening of the V-shaped groove. The middle part of the elastic reset unit is slidably connected to the first circular through groove.

[0007] Preferably, the tensioning plate unit includes a tensioning plate body, which is bent into an L-shape. A pentagonal through groove is provided at the end of the long side of the tensioning plate body, and a second circular through groove is provided at the end of the short side of the tensioning plate body. The long side of the tensioning plate body is slidably connected to the rectangular through groove.

[0008] Preferably, the first circular through groove and the second circular through groove are of equal size and coaxial.

[0009] Preferably, the elastic reset unit includes a pin, the head of which abuts against the short side of the tensioning plate body, and the rod of which passes through the first circular through groove and the second circular through groove in sequence. A spring is fitted onto the outer circumferential surface of the pin shaft. One end of the spring abuts against the short side of the tensioning plate body, and the other end of the spring abuts against the fixing base body. A retaining pin is installed at the tail of the pin, and a baffle is also fitted at the tail of the pin. During the tensioning operation, one end of the baffle plate abuts against the V-groove, and the other end of the baffle plate abuts against the locking pin.

[0010] Compared with the prior art, the beneficial technical effects of this utility model are as follows: This utility model is a plate-type tensioning fixture.

[0020] When the clothes hanger hook is clamped, the tensioning plate body extends from the fixing base body, at which time the spring on the outer circumference of the pin is compressed; When the hanger hook is hung on the pentagonal through slot, the hanger hook can be clamped by the tension plate body under the action of the spring force, so that one end of the hanger hook abuts against the V-shaped slot and the other end of the hanger hook abuts against the sharp corner of the pentagonal through slot, thus achieving the clamping operation of the hanger hook. The clamping process is convenient and quick.
