Description

Technical Field

[0001] This utility model relates to the technical field of metal pressure testing devices, specifically a wear-resistant metal pressure testing device. Background Technology

[0002] Metal parts refer to workpieces made of metal. After the production of metal parts is completed, testing equipment is needed to perform pressure testing on the metal parts.

[0003] Patent document CN221650059U discloses a pressure testing device for metal parts production, including a worktable. A side plate is fixedly connected to the upper surface of the worktable, and a groove is formed on an adjacent side of the side plate. A dual-axis motor is fixedly connected to the upper surface of the worktable, and a placement frame is also fixedly connected to the upper surface of the worktable. Threaded rods are fixedly connected to the output ends of the dual-axis motor. A guide rod is provided on the outer wall of the threaded rod, and the guide rod is fixedly connected via the side plate. A clamping plate is connected to the outer wall of the threaded rod and the guide rod. A slot is formed on one side of the clamping plate, and a buckle is engaged on the inner wall of the slot. In this invention, the metal part is placed on the placement frame, and then the dual-axis motor is started. The dual-axis motor drives the clamping plate to move along the trajectory of the guide rod, and the anti-slip pads on the clamping plate hold the metal part. This design achieves the effect of conveniently clamping metal parts of different sizes.

[0004] Although the aforementioned application document describes a dual-axis motor driving the clamping plate to move along the guide rod's trajectory, with anti-slip pads on the clamping plate holding the metal parts, achieving the effect of conveniently clamping metal parts of different sizes, it relies on the guide rod to ensure the clamping plate's movement trajectory and the threaded rod to provide driving force. However, when clamping large metal parts or requiring high clamping force and undergoing high-pressure testing, the clamping plate will be subjected to a large reaction force. If the diameter, material, or support strength of the guide rod or threaded rod is insufficient, bending deformation may occur. This deformation will directly cause the clamping center to shift, affecting the workpiece positioning.

[0005] Therefore, a wear-resistant metal pressure testing device is proposed to solve the problems mentioned above. Utility Model Content

A movable plate 23 is fixedly connected to the top of the slider 22. A first hydraulic chamber 24 is fixedly connected to the side of the movable plate 23. A first hydraulic rod 25 is slidably connected to one end of the first hydraulic chamber 24 by a piston. A first clamping plate 26 is fixedly connected to the side of the first hydraulic rod 25. A vertical plate is fixedly connected to the top of the base 1. A second hydraulic chamber 27 is fixedly connected to the inner wall of the vertical plate.

The first hydraulic chamber 24 and the second hydraulic chamber 27 are connected by a connecting hose. A drive movable plate 23 is installed inside the base 1. A drive assembly is provided on the top of the base 1.

[0019] The drive assembly includes a partition 213, which is fixedly connected to the front of the inner wall of the base 1. A rotating rod 214 is rotatably connected to the top of the partition 213 via a bearing. A rotating block 215 is fixedly connected to the top of the rotating rod 214. A connecting rod 216 is hinged to the top of the rotating block 215. A hinge rod 217 is fixedly connected to the top of the connecting rod 216.

[0020] The hinge rod 217 is hinged to the bottom of the slider 22.

[0021] A motor 212, which provides the drive source, is fixedly connected to the bottom of the inner wall of the base 1.

[0022] The first clamping plate 26 is equipped with a first pulley 210 on its front side, and the second clamping plate 29 is equipped with a second pulley 211 on its side side.

[0023] The rotating rod 214 moves through the partition 213, and the extended end of the rotating rod 214 extends towards the bottom of the partition 213. The extended end of the rotating rod 214 is fixedly connected to the output end of the motor 212.

[0024] A spring is movably sleeved on the outer wall of the first hydraulic rod 25, with the two ends of the spring fixedly connected to the side of the first clamping plate 26 and the side of the moving plate 23, respectively.

[0025] In practical use, the test piece is placed on top of the base 1, and the motor 212 is started. The motor 212 drives the rotating rod 214 to rotate, which in turn drives the rotating block 215 to rotate clockwise.
