Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing and relates to a bottom plate strength detection device. Background Art

[0002] A baseplate is typically the foundational support component of mechanical or electronic equipment. It provides stable support for the equipment and is used to mount and secure other components. It must possess sufficient strength and rigidity to ensure stability and safety during operation. This requires specialized strength testing equipment to inspect the produced baseplates. However, some existing baseplate strength testing devices require the baseplate to be placed in a slot for testing, making it inconvenient to remove the baseplate after testing. Therefore, designing a baseplate strength testing device to facilitate baseplate removal is essential. Summary of the Invention

[0003] The purpose of the utility model is to solve the above problems in the existing technology and to propose a bottom plate strength detection device.

[0004] The cam is provided with a support plate at the bottom of the support plate, and a pressure sensor is installed at the bottom of the support plate, and a displacement sensor is installed at both ends of the support plate. One end of the placement slot is a through slot, and a stopper is installed at the through slot opening of the support plate, which is connected to the rotating shaft by a connecting piece. One end of the rotation rod is connected to the driving motor, and the other end of the rotation rod is rotatably connected to the frame. A group of mounting slots are opened on both sides of the stopper to slide in the mounting slot, and one end of the locking bar is connected to the bottom of the mounting slot by a spring, and the other end of the locking bar is clamped in the corresponding slot on the frame. The slot is provided with a push rod motor, and the rod part of the push rod motor is installed with a push block matching the end of the locking bar.

[0005] The working principle of the utility model is as follows: the base plate sample that needs strength testing is placed in the placement slot through the through slot, the driving motor is controlled to flip up the block, and the locking strips on both sides of the block are clamped in the card slot and fixed under the action of the spring, and then the pressure plate is controlled to be pressed down by the hydraulic press, and the pressure intensity when the base plate is broken is detected by the pressure sensor, so as to obtain the compressive performance of the base plate, and at the same time, the deformation of the base plate when under pressure is detected by the displacement sensor, so as to obtain the toughness performance of the base plate, and thus the seismic performance. After the test is completed, the push rod motor is used to control the push block to push out the locking strip, and the driving motor is used to flip down the block, so that the base plate can be easily removed from the through slot.

[0006] The outer end portion of the locking strip is arranged in an arc shape, and the portion of the frame that contacts the locking strip when the stopper is flipped upward is also arranged in an arc shape.

[0007] With the above structure, the locking bar can be easily inserted into the card slot.

[0008] The displacement sensor and the pressure sensor are mounted on the frame via a snap-fit structure.

[0009] The above structure is adopted for easy disassembly.

[0010] The support plate is slidably placed in the placement groove.

[0011] With the above structure, it is convenient to disassemble and assemble the pressure sensor after taking out the support plate.

[0012] A control unit for controlling various mechanisms is installed inside the frame.

[0013] Compared with the existing technology, this bottom plate strength detection device has the following advantages: the utility model sets a structure that cooperates with a pressure sensor and a displacement sensor, while ensuring the detection effect, and sets a block structure to facilitate the removal of the bottom plate after the detection is completed.
