Description

Technical Field

[0001] This utility model relates to a ceramic ball pressure resistance testing device, belonging to the technical field of ceramic ball testing equipment. Background Technology

[0002] Ceramic balls possess properties such as wear resistance and high-temperature resistance, and are widely used in various fields, serving as catalysts, fillers, and abrasives. After ceramic balls are manufactured, their pressure resistance needs to be tested, which requires pressure testing equipment.

[0003] Currently, existing ceramic ball pressure testing equipment typically includes a base, top plate, support column, hydraulic cylinder, and adjusting screw. Pressure is applied to the ceramic ball via the hydraulic cylinder, and the adjusting screw adjusts the position of the pressure plate. However, existing equipment has several shortcomings: First, the components supporting the ceramic ball are mostly integral fixed structures, requiring complete replacement when worn, increasing costs and being cumbersome; second, the piston rod of the hydraulic cylinder is easily contaminated by dust and impurities during extension and retraction, reducing the cylinder's lifespan. Utility Model Content

[0004] This invention provides a ceramic ball pressure resistance testing device to solve the problems mentioned in the background art.

[0005] This utility model relates to a ceramic ball pressure resistance testing device, including a base, a top plate, and a support column connecting the two. A hydraulic cylinder is provided on the base, and an adjusting screw is provided on the top plate. A supporting frustum is fixed to the top of the piston rod of the hydraulic cylinder. A mounting boss is provided on the top of the supporting frustum. A replacement support plate and a pressure plate are provided above the mounting boss. The bottom of the replacement support plate is provided with an embedding groove for embedding the mounting recess. The top of the replacement support plate is provided with a support groove that cooperates with the pressure plate. A flexible protective sleeve is provided on the outside of the supporting frustum to protect the piston rod. A removable and replaceable pressure plate is provided at the bottom of the adjusting screw.

[0006] As a preferred option, the flexible protective sleeve is a protective bag. The upper end of the protective bag is fixed to the outer wall of the supporting truncated cone, and the lower end of the protective bag is fixed with a support ring, which is fixed to the base. Using a protective bag as a flexible protective sleeve provides good elasticity, allowing it to adapt to the extension and retraction of the piston rod and always effectively wrapping the piston rod. The fixing method of fixing the upper end of the protective bag to the outer wall of the supporting truncated cone and the lower end to the base via the support ring makes the installation of the protective bag more stable, preventing the protective bag from shifting or falling off during piston rod movement, ensuring the stability of the protective effect. At the same time, this fixing structure is simple and facilitates the replacement and maintenance of the protective bag.

[0007] As a preferred embodiment, the embedded groove and the supporting groove are connected by a threaded hole, and a fastening bolt for fixing the pressure-bearing disc is installed in the threaded hole, making the pressure-bearing disc more securely fixed. A top-pressure hole is provided in the middle of the replacement support disc, connecting the embedded groove and the supporting groove. The top-pressure hole facilitates the ejection of the pressure-bearing disc via a rod.

[0008] As a preferred embodiment, the adjusting screw is threaded onto the top plate. A rotating wheel is located at the top of the adjusting screw, and a mounting plate is rotatably mounted at the bottom of the adjusting screw. A fixing bolt for securing the pressure plate is located on the outer top of the mounting plate. This allows the operator to easily adjust the height of the adjusting screw by rotating the rotating wheel, thereby achieving precise adjustment of the pressure plate height.

[0009] As a preferred embodiment, the bottom outer side of the mounting plate is covered with a dust bag, and the top opening of the dust bag is fixed to the bottom of the top plate. The dust bag effectively protects the mounting plate and the lower end of the adjusting screw, preventing dust generated during the testing process from sticking to the adjusting screw, avoiding dust from causing thread jamming or wear on rotating parts, ensuring smooth adjustment of the adjusting screw and extending the service life of each rotating component. At the same time, the dust bag has a simple structure and is easy to install and replace.

[0010] As a preferred embodiment, protective baffles are fixed to the left, right, and rear sides of the base and top plate. A protective perforated plate is hinged to the front left support column, and a protective iron plate is fixed to the inner side of the protective perforated plate. A magnet that cooperates with the protective iron plate is fixed to the front right support column. The protective baffles and protective perforated plates work together to form a comprehensive protective structure, which can effectively block the fragments generated when the ceramic ball breaks during the testing process, avoid injury to the operator from the fragments, and improve the safety of equipment use.

[0011] As a preferred embodiment, the left end of the protective perforated plate is hinged with a C-shaped adjusting sleeve, which is fitted onto the support column. A fastening bolt is provided at the connection port of the adjusting sleeve. The design of the C-shaped adjusting sleeve fitting onto the support column, together with the fastening bolt at the connection port, allows the adjusting sleeve to move up and down along the support column and be fixed at any height.

[0012] As a preferred embodiment, the hydraulic cylinder is equipped with a pressure sensor to detect its pressure. The pressure sensor is connected to a PLC controller, which in turn is connected to an operator screen. The pressure sensor can accurately detect the output pressure of the hydraulic cylinder in real time and transmit the pressure data to the PLC controller. The PLC controller processes and converts the data and displays it in real time on the operator screen, allowing the operator to clearly understand the pressure changes during the detection process.

[0013] This utility model has the following beneficial effects:

[0014] The mounting boss and embedded groove enable quick positioning and installation of the support plate for replacement. The support groove also limits the pressure plate, making the assembly of the support plate and pressure plate replacement more convenient. Wear on the pressure plate can be replaced separately. The flexible protective sleeve provides full protection for the piston rod of the hydraulic cylinder, preventing ceramic debris and dust generated during the testing process from adhering to the piston rod surface or entering the hydraulic cylinder, reducing piston rod wear and the risk of hydraulic cylinder failure, and extending the service life of the equipment. The design of a removable and replaceable pressure plate at the bottom of the adjusting screw makes the pressure plate replacement operation simpler. Attached Figure Description
