Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
As shown in fig. 1 to 4, a shear test jig for a welding sample includes:
the device comprises a base 1, wherein a support 6 is welded on the left side of the upper surface of the base 1, a first air cylinder 7 is vertically fixed at the bottom of the inner wall of the support 6, an upper clamping plate 4 is connected to the bottom of the first air cylinder 7 in a transmission manner, a lower clamping plate 2 is fixed on the upper surface of the base 1, the lower clamping plate 2 is positioned under the upper clamping plate 4, cutter grooves 5 which correspond to one another one by one are formed in the middle of the adjacent surfaces of the upper clamping plate 4 and the lower clamping plate 2, a baffle 13 is welded on the right side of the lower clamping plate 2, a through hole which is communicated with the left side and the right side is formed in the baffle 13, the through hole is communicated with the cutter grooves 5, a second air cylinder 8 is fixed on the right side of the upper surface of the base 1, a U-shaped rod 12 is connected to the left end of the second air cylinder 8 in a transmission;
specifically, when a user needs to cut a sample 3, the sample 3 is firstly placed on the lower clamp plate 2, then the first air cylinder 7 is started to drive the upper clamp plate 4 to move downwards, the sample 3 can be clamped between the upper clamp plate 4 and the lower clamp plate 2, after the sample 3 is firmly pressed by the upper clamp plate 4, the first air cylinder 7 is closed, the second air cylinder 8 is started to drive the U-shaped rod 12 to move leftwards, the U-shaped rod 12 can drive the cutter wheel 14 in the baffle 13 to move towards the cutter groove 5, the sample 3 can be cut, and when the cutter wheel 14 cuts the sample 3, the cutter wheel 14 is located in the cutter groove 5 of the upper clamp plate 4 and the lower clamp plate 2, and the sample 3 is clamped between the upper clamp plate 4 and the lower clamp plate 2, so that scraps generated when the cutter wheel 14 cuts the sample 3 can be prevented from splashing, the safety of the user is ensured, and the working environment is clean;
