Description

Technical Field

[0001] This utility model relates to the field of shearing machines and specifically to a dynamic compression shearing test fixture. Background Technology

[0002] A hydraulic shearing machine is a machine that uses a moving upper blade and a fixed lower blade with a reasonable blade gap to apply shearing force to metal sheets of various thicknesses, causing the sheets to break and separate to the required dimensions.

[0003] For example, the Chinese patent with publication number CN203824846U, entitled "(Pressure-type Single-shear Test Fixture)," includes: a main blade holder for the single-shear fixture, single-shear fixture pads, single-shear fixture pressure blocks, a single-shear fixture cutter holder, and single-shear fixture blades. The blades are mounted on the main blade holder and the cutter holder. Two pads are placed on the left and right sides of the main blade holder. Two pressure blocks are placed on the top and bottom sides of the pads and secured with bolts. This invention uses only one blade holder and can be fitted with different specifications of cutter blades, saving on material and processing costs.

[0004] However, existing compression and shear testing fixtures have problems with unstable clamping of the object being tested, leading to detachment. Therefore, they do not meet the current requirements. To address this, we propose a dynamic compression and shear testing fixture. Utility Model Content

[0005] The purpose of this utility model is to provide a dynamic compression-shear test fixture to solve the problem mentioned in the background art that the existing compression-shear test fixtures and equipment have unstable clamping and falling off of the object to be tested during use.

[0007] Also includes:

[0008] An embedded cavity is reserved and installed inside the upper surface of the compression-shear testing equipment at the middle position. The embedded cavity is cross-shaped. A hydraulic fixing rod is provided at the lower part of the inside of the compression-shear testing equipment. A placement platform is provided on the upper end of the hydraulic fixing rod. The placement platform and the hydraulic fixing rod can move up and down. A flip clamping plate is provided on the upper side of the outer wall of the placement platform. There are four flip clamping plates. The four flip clamping plates are connected to the placement platform for flipping and rotating through four rotating shafts.

[0009] Preferably, the inner wall of one end of the flip-grip plate is provided with a clamping and stabilizing rod, and four clamping and stabilizing rods are provided, with one end of the clamping and stabilizing rod fixedly connected to the inner wall of one end of the flip-grip plate.

[0010] Preferably, the inner wall of the cross-shaped reserved embedded cavity is provided with limiting rotating wheels, and four limiting rotating wheels are provided, all of which are rotatably connected to the reserved embedded cavity.

[0011] Preferably, the front end of the compression-shear testing equipment is provided with an operating mechanism, and the interior of the placement platform is provided with a placement cavity.

[0012] Preferably, a maintenance plate is provided on one side of the compression-shear testing equipment, and the maintenance plate is threadedly connected to the compression-shear testing equipment by hexagonal bolts, and four hexagonal bolts are provided.

[0013] Preferably, the inspection plate has a heat dissipation slot inside, and there are several heat dissipation slots, all of which are integrally formed with the inspection plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the setting of a placement platform, a placement cavity, a flip clamping plate, a clamping stabilizing rod, and a limiting rotating wheel, allows the object to be tested to be placed inside the placement cavity of the placement platform. Then, the placement platform is moved downward, thereby causing the flip clamping plate to flip as it passes the position of the limiting rotating wheel, adjusting the flip clamping plate to an upright state. The clamping stabilizing rod set on the flip clamping plate can also be uprighted along with the flip clamping plate, thereby clamping the object to be tested. This effectively avoids the problem of unstable clamping and falling off of the object to be tested in existing compression and shear testing fixtures. Attached Figure Description
