Description

Technical Field

[0001] This utility model relates to the field of grinding wheel processing technology, and in particular to a grinding wheel pressure resistance testing mechanism. Background Technology

[0002] As a commonly used grinding tool, the compressive strength of grinding wheels directly affects their safety and stability during use. Therefore, after the grinding wheels are manufactured, they must undergo rigorous compressive strength testing. Currently, there are many types of grinding wheel compressive strength testing equipment on the market, but their core functions all revolve around applying pressure to the grinding wheel and testing its compressive strength limit.

[0003] However, existing testing equipment has many shortcomings in practical applications: on the one hand, the positioning accuracy of the pressure application mechanism and the receiving component of some equipment is insufficient, making it difficult to ensure that the pressure acts perpendicularly on the center of the grinding wheel, resulting in deviations in the test results; on the other hand, the grinding wheel is prone to breakage when it reaches its ultimate strength during the compressive strength test, and the resulting flying debris may pose a safety hazard to the operator, while the protective structure of traditional equipment is imperfect and the protective effect is poor; at the same time, the pressure stroke of some equipment is inconvenient to adjust, making it difficult to adapt to the testing needs of grinding wheels with different thicknesses. Therefore, this utility model proposes a grinding wheel compressive strength testing mechanism. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a grinding wheel pressure resistance testing mechanism to solve the problems of low positioning accuracy, poor protection effect and insufficient adaptability of existing equipment.

[0005] To solve the above-mentioned technical problems, the present invention provides a grinding wheel pressure resistance testing mechanism, including an operating table, wherein a pressure applying mechanism is fixedly connected to the top of the operating table to perform pressure application on the placed grinding wheel. A receiving component is provided at the top center of the operating table, and the receiving component is arranged coaxially with the pressure applying mechanism to fix the position of the grinding wheel and cooperate with the pressure applying mechanism to perform a pressure resistance test on the grinding wheel. The rear wall of the pressure applying mechanism is bolted with a protective plate, and the front wall of the pressure applying mechanism is movably connected with a protective component to protect against the flying debris when the grinding wheel is damaged during the pressure test.

[0006] The present invention is further configured such that: the pressure applying mechanism includes pillars symmetrically installed on the top of the operating table, the top of the two pillars are bolted to a top plate, an adjusting screw is threaded through the center of the top plate, an adjusting plate is rotatably connected to the bottom of the adjusting screw, a hydraulic cylinder is bolted to the bottom center of the adjusting plate, and a pressure applying block is bolted to the drive end face of the hydraulic cylinder.

[0007] Through the above technical solution, rotating the adjusting screw can drive the adjusting plate to move up and down along the support column, thereby adjusting the initial distance between the hydraulic cylinder and the receiving component to adapt to the testing requirements of grinding wheels of different thicknesses; during testing, the hydraulic cylinder drives the pressure block to apply pressure downward at a uniform speed, and the stable driving force of the hydraulic cylinder ensures the uniformity of pressure application and improves the accuracy of test results.

[0008] The present invention is further configured such that: a sliding groove is provided on the opposite surfaces of the two pillars, and sliders are symmetrically fixedly connected to both ends of the adjusting plate, and the sliders are slidably connected to the inside of the sliding groove.

[0009] Through the above technical solution, the adjustment plate slides in conjunction with the slide groove of the support column, which limits the movement trajectory of the adjustment plate and ensures that the adjustment plate always moves in the vertical direction. This ensures that the pressure applied by the hydraulic cylinder-driven pressure block is always perpendicular to the surface of the grinding wheel, thus avoiding the distortion of test data due to pressure deviation.

[0010] The present invention is further configured such that a rotating wheel is fixedly connected to the top of the adjusting screw.

[0011] Through the above technical solution, the rotary wheel increases the gripping force area of ​​the adjusting screw, making it easier for operators to manually rotate the adjusting screw, reducing the difficulty of adjusting the position of the adjusting plate, and improving the ease of use of the equipment.

[0012] The present invention is further configured such that: the receiving component includes a receiving seat bolted to the center of the top of the operating table, and a storage box is sleeved on the outside of the receiving seat, and the storage box is embedded in the top of the operating table.

[0013] With the above technical solution, the receiving seat and the pressure applying mechanism are set on the same axis, which can accurately position the grinding wheel and ensure that the center of the grinding wheel is aligned with the center of the pressure block; the storage box is set outside the receiving seat, which can collect the debris after the grinding wheel breaks, prevent the debris from falling onto the operating table surface and being difficult to clean, and further prevent the debris from splashing.

[0014] The present invention is further configured such that: the protective component includes a cylinder installed on the top of the top plate, the drive end of the cylinder is bolted to a baffle, and guide rails are symmetrically slidably connected to both sides of the baffle, and the guide rails are respectively installed on the front wall of the two pillars.

[0015] Through the above technical solution, the front cylinder drives the baffle to move downward along the guide rail, so that the baffle blocks the front of the pressure mechanism and the receiving component, forming a closed protective space with the rear wall guard plate; when the grinding wheel breaks, the baffle can effectively block the debris from flying forward, and the guard plate can block the debris from flying backward, thus fully protecting the personal safety of the operators.

[0016] The present invention is further configured such that the baffle is made of transparent plastic material.

[0017] Through the above technical solution, the transparent plastic baffle can provide protection without affecting the operator's observation of the grinding wheel's condition during the test. This allows for timely monitoring of the test progress and the damage to the grinding wheel, thus improving the intuitiveness of the test operation.

[0018] The beneficial effects of this utility model are as follows: 1. The grinding wheel pressure resistance testing mechanism proposed in this utility model is arranged coaxially with the receiving component and the pressure applying mechanism. With the guiding effect of the slider and the slide groove, it ensures that the pressure is applied vertically and evenly to the grinding wheel, effectively avoiding test deviation and improving the accuracy of test data. 2. The grinding wheel pressure resistance testing mechanism proposed in this utility model forms all-round protection by using the transparent baffle of the protective component and the rear wall guard plate. At the same time, it collects debris through the storage box, which not only prevents debris from flying and ensures personnel safety, but also facilitates subsequent cleaning.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0022] like Figures 1-3As shown, a grinding wheel pressure testing mechanism includes an operating table 1. A pressure applying mechanism 2 is fixedly connected to the top of the operating table 1 to apply pressure to the placed grinding wheel. The pressure applying mechanism 2 includes pillars 21 symmetrically installed on the top of the operating table 1. A top plate 22 is bolted to the top of the two pillars 21. An adjusting screw 23 is threaded through the center of the top plate 22. A rotating wheel 231 is fixedly connected to the top of the adjusting screw 23. The rotating wheel 231 increases the gripping force area of ​​the adjusting screw 23, making it easier for the operator to manually rotate the adjusting screw 23, reducing the difficulty of adjusting the position of the adjusting plate 24, and improving the ease of use of the equipment. An adjusting plate 24 is rotatably connected to the bottom of the adjusting screw 23. Slide grooves 211 are opened on the opposite surfaces of the two pillars 21. Sliding blocks 241 are symmetrically fixedly connected to both ends of the adjusting plate 24, and the sliding blocks 241 are slidably connected. Inside the slide groove 211, the adjusting plate 24 slides in conjunction with the slide groove 211 of the support column 21 via the slider 241, limiting the movement trajectory of the adjusting plate 24 and ensuring that the adjusting plate 24 always moves vertically. This ensures that the pressure applied by the hydraulic cylinder 25 driving the pressure block 26 is always perpendicular to the surface of the grinding wheel, avoiding distortion of test data due to pressure deviation. The hydraulic cylinder 25 is bolted to the bottom center of the adjusting plate 24, and the pressure block 26 is bolted to the drive end face of the hydraulic cylinder 25. Rotating the adjusting screw 23 can drive the adjusting plate 24 to move up and down along the support column 21, thereby adjusting the initial distance between the hydraulic cylinder 25 and the receiving component 3 to adapt to the testing requirements of grinding wheels of different thicknesses. During testing, the hydraulic cylinder 25 drives the pressure block 26 to apply pressure downward at a uniform speed. The stable driving force of the hydraulic cylinder 25 ensures the uniformity of pressure application and improves the accuracy of test results.

[0023] like Figure 3 As shown, a receiving component 3 is provided at the top center of the operating table 1, and the receiving component 3 is coaxially arranged with the pressure applying mechanism 2 to fix the position of the grinding wheel and cooperate with the pressure applying mechanism 2 to perform a pressure resistance test on the grinding wheel. The receiving component 3 includes a receiving seat 31 bolted to the top center of the operating table 1, and a storage box 32 is sleeved on the outside of the receiving seat 31. The storage box 32 is embedded in the top of the operating table 1. The receiving seat 31 and the pressure applying mechanism 2 are coaxially arranged, which can accurately position the grinding wheel and ensure that the center of the grinding wheel is aligned with the center of the pressure block 26. The storage box 32 is sleeved on the outside of the receiving seat 31 to collect the debris after the grinding wheel breaks, preventing the debris from falling onto the surface of the operating table 1 and making it difficult to clean, and further preventing debris from splashing.

[0024] like Figure 3As shown, a protective plate 4 is bolted to the rear wall of the pressure applying mechanism 2, and a protective component 5 is movably connected to the front wall of the pressure applying mechanism 2 to protect against the flying debris when the grinding wheel breaks during the pressure test. The protective component 5 includes a cylinder 51 installed on the top of the top plate 22. A baffle 52 is bolted to the drive end of the cylinder 51. The baffle 52 is made of transparent plastic. While providing protection, the transparent plastic baffle 52 does not affect the operator's observation of the grinding wheel's state changes during the test, making it easy to keep track of the test progress. The damage to the grinding wheel enhances the intuitiveness of the test operation. The baffle 52 is symmetrically slidably connected to the two sides of the guide rail 53, and the guide rail 53 is respectively installed on the front wall of the two pillars 21. Before the test, the cylinder 51 drives the baffle 52 to move downward along the guide rail 53, so that the baffle 52 blocks the front of the pressure mechanism 2 and the receiving component 3, forming a closed protective space with the guard plate 4 on the rear wall. When the grinding wheel breaks, the baffle 52 can effectively prevent the debris from flying forward, and the guard plate 4 can prevent the debris from flying backward, fully ensuring the personal safety of the operator.

[0025] In use, the grinding wheel to be tested is first placed on the receiving seat 31 of the receiving assembly 3, ensuring that the center of the grinding wheel is aligned with the center of the receiving seat 31. The rotating wheel 231 is rotated, and the adjusting screw 23 drives the adjusting plate 24 to move up and down along the slide groove 211 of the support column 21, adjusting the hydraulic cylinder 25 to a suitable height. The cylinder 51 is started, driving the baffle 52 to move down along the guide rail 53 to the protective position, forming a closed protective space with the guard plate 4. Then the hydraulic cylinder 25 is started, driving the pressure block 26 to apply pressure to the grinding wheel at a uniform speed. The operator observes the state of the grinding wheel through the transparent baffle 52 until the grinding wheel breaks, and records the relevant test data. After the test is completed, the equipment is turned off, the cylinder 51 drives the baffle 52 to reset, and the debris in the storage box 32 is cleaned before the next test.
