Detailed Description

The trial jig of the present invention will be further described with reference to specific embodiments to assist those skilled in the art in more fully, accurately and deeply understanding the technical solutions of the present invention.

Example 1

As shown in fig. 1 to 2, the trial jig of the present embodiment includes a connecting plate 40, a pressing arm 20, a connecting arm 30, a locking mechanism 10, a pressing head 60, and a jig stage 70. One end of the pressing arm 20 is connected to the connecting arm 30 by a fastener, and the lower end of the connecting arm 30 is connected to the connecting plate 40 by a hinge. The other end of the pressing arm 20 is provided with a pressing head 60 engaged with the jig stage 70. The clamp table 70 is disposed on the connection plate 40, and the connection arm 30 and the clamp table 70 are respectively located at both sides of the connection plate 40. The connecting plate 40 is further provided with a limiting block 50 which is matched with two side surfaces of the pressing arm 20 and limits the pressing degree of the pressing arm. The connecting plate 40 is fixed to the base 80 by a fastener. The locking mechanism 10 comprises a rod body 15, a limiting portion 13 is arranged on the upper portion of the rod body 15, a handle 14 is arranged at the upper end of the rod body 15, an anti-falling nut 12 is arranged on the lower portion of the rod body, and an external thread 11 is arranged on the outer wall of the lower end of the rod body. The rod body 15 passes through the pressure arm 20, the limiting part 13 is positioned above the pressure arm 20, and the anti-falling nut 12 is positioned below the pressure arm 20. The outer wall of the lower end of the rod body 15 is provided with an external thread 11, the connecting plate 40 is provided with a threaded hole, and the inner wall of the threaded hole is provided with an internal thread meshed with the external thread 11. In this embodiment, the limiting portion 13 is a sleeve sleeved on the rod body 15.

The trial-manufacture fixture of the embodiment has the advantages that the locking mechanism is screwed clockwise through the handle, and when the limiting end is tightly attached to the pressing arm, the pressing state can be realized; through anticlockwise locking mechanism of twisting of handle, after anticreep nut and the laminating of pressure arm, can realize pressing the arm open mode.

The trial-manufacture fixture of the embodiment has the advantages of simple structure, low processing difficulty and higher processing efficiency; through manual screwing, the pressing force is ensured to be in a certain controllable range, the failure mode is bolt sliding, and the detectability is high; and the manufacturing cost is lower, and the cost is only about 10 percent of that of the manual quick clamp.

It is obvious to those skilled in the art that the specific embodiments are only exemplary descriptions of the present invention, and it is obvious that the specific implementation of the present invention is not limited by the above-mentioned manner, and various insubstantial modifications made by the method concept and technical scheme of the present invention are within the protection scope of the present invention.
