Description

Technical Field

[0001] The utility model relates to the technical field of coated abrasive tool manufacturing equipment, in particular to a water resistance testing device for resin coated abrasive tools. Background Art

[0002] Resin-coated abrasives are widely used in the precision grinding of metal and non-metallic materials due to their high efficiency, low cost and good processing performance. Resin-coated abrasives often face the problem of water erosion during use, which may lead to a decrease in the performance of the abrasive or even failure. Therefore, evaluating the water resistance of resin-coated abrasives is crucial to ensure their reliability and safety. At present, most water resistance testing devices on the market use static immersion or simple spraying methods to simulate the water resistance of resin-coated abrasives in actual use. This testing method cannot simulate the complex moisture conditions in the actual use environment, such as temperature changes, water flow impact, etc., which makes the water resistance of resin-coated abrasives in actual use inconsistent with the water resistance in the test, resulting in the test results being not of reference value. In view of this, the present utility model is proposed. Utility Model Content

[0021] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0022] See also Figure 1-Figure 2 , Figure 1 This is a schematic diagram of the three-dimensional structure of the water resistance testing device provided by an embodiment of the present utility model; Figure 2The figure is a schematic diagram of a partial three-dimensional structure of a spray assembly in a water resistance testing device provided by an embodiment of the present invention. The resin-coated abrasive water resistance testing device 1 of the present invention comprises a frame 11, a clamping member 12, a grinding assembly 13 and a spray assembly 14. The clamping member 12 is mounted on the frame 11 to clamp the workpiece. The grinding assembly 13 is mounted on the frame 11 to drive the abrasive to grind the workpiece. The spray assembly 14 comprises a first water tank 141, a second water tank 142, a water receiving tray 143, a spray pipe 144 and a spray head 145. The first water tank 141 and the second water tank 142 are both arranged below the frame 11. The water receiving tray 143 is fixed to the frame 11 and Located between the clamping member 12 and the first water storage tank 141, the bottom of the water receiving tray 143 is provided with a return hole 1431 aligned with the first water storage tank 141, one end of the spray pipe 144 is connected to a two-way diverter pipe 146, and the two ends of the two-way diverter pipe 146 are respectively connected to the first water storage tank 141 and the second water storage tank 142, the other end of the spray pipe 144 is connected to the spray head 145, and the spray head 145 is directed to the clamping member 12, and a rotatable adjustment disk is provided on the spray head 145 to adjust the spray water pressure of the spray head 145.

[0023] When the abrasive tool is subjected to a water resistance test, the workpiece is placed on the clamping member 12 for clamping and fixing, and the resin-coated abrasive tool is connected to the grinding assembly 13, so that the resin-coated abrasive tool is driven to grind the workpiece under the movement of the grinding assembly 13. During the grinding process, the workpiece is sprayed with water through the spray assembly 14, thereby achieving a water resistance test when the abrasive tool is grinding the workpiece. By adjusting the spray assembly 14 to simulate different spraying environments, the water resistance test of the abrasive tool is made closer to the actual use environment, thereby improving the accuracy of the water resistance test results of the abrasive tool and improving the reference value of the water resistance of the abrasive tool.

[0024] When the spray assembly 14 is used to spray the workpiece, hot water is filled into the first water tank 141 and cold water is filled into the second water tank 142. The hot water and cold water flow into the spray pipe 144 from both ends of the two-way diversion pipe 146 respectively, and are sprayed out from the spray head 145 after passing through the spray pipe 144. By controlling the temperature of the hot water and the cold water, the spray head 145 can spray water at the required temperature, so that the water temperature during the mold water resistance test is closer to the water temperature during actual use. By rotating the adjusting disk, the spray water pressure of the spray head 145 is adjusted, so that the water flow impact during the mold water resistance test can be closer to the water flow impact during actual use.

[0025] In the above embodiment, the clamping member 12 can be any one of a vise and a suction cup to clamp and fix the workpiece. The grinding assembly 13 includes a grinding robot 131, a rotary drive member 132 and a grinding fixture 133. The rotary drive member 132 is installed at the end of the grinding robot 131 and connected to the grinding fixture 133. The clamping tool clamps the grinding tool and drives the grinding tool to rotate under the drive of the rotary drive member 132, so that the rotating grinding tool grinds the workpiece, wherein the rotary drive member 132 uses a motor to drive the grinding fixture 133 to rotate. The connection method between the grinding tool and the grinding fixture 133 includes any one of a wrapping connection and an adhesive connection, that is, the grinding tool is wrapped on the grinding fixture 133 or the grinding tool is attached to the grinding fixture 133 using Velcro or glue, so that the grinding fixture 133 drives the grinding tool to grind.

[0026] The water in the first water tank 141 and the second water tank 142 can be water with a pre-adjusted temperature so that the temperature of the water sprayed by the spray head 145 is the required temperature. When the temperature of the sprayed water needs to be adjusted, water of different temperatures can be poured into the first water tank 141 and the second water tank 142 respectively to adjust the required spraying temperature.

[0027] Among them, there are multiple spray holes on the adjustment disk. When the adjustment disk is rotated, different spray holes are aligned with the spray head 145, so as to adjust the spray water pressure. That is, when the small-diameter spray holes are adjusted to align with the spray head 145, the water pressure when the spray head 145 sprays increases, and the spray water flow decreases at the same time. When the large-diameter spray holes are adjusted to align with the spray head 145, the water pressure when the spray head 145 sprays decreases, and the spray water flow increases.

[0028] In an embodiment of the present utility model, a plurality of water leakage holes are opened on the frame 11, and the water receiving tray 143 is located on the frame 11 below the water leakage holes, so that the water sprayed by the sprinkler head 145 flows into the water receiving tray 143 from the water leakage holes. The bottom surface of the water receiving tray 143 is an inclined surface, and the return hole 1431 is at the lowest position of the inclined surface, so that the water entering the water receiving tray 143 flows into the return hole 1431 along the inclined surface and flows back to the first water storage tank 141 from the return hole 1431.

[0029] In an embodiment of the present utility model, a mixing valve 1441 is provided at the connection between the two-way diversion pipe 146 and the spray pipe to regulate the flow of water from the first water tank 141 and the second water tank 142 into the spray pipe 144, so that the water in the first water tank 141 and the second water tank 142 is mixed under the action of the mixing valve 1441 to adjust the water temperature when the sprinkler head 145 is spraying.

[0030] In an embodiment of the present utility model, the first water tank 141 and the second water tank 142 are respectively provided with a first booster pump and a second booster pump, and the first booster pump and the second booster pump are respectively connected to the two ends of the two-way shunt pipe 146, so that water in the first water tank 141 is extracted under the action of the first booster pump, and water in the second water tank 142 is extracted under the action of the second booster pump, and the water is sprayed out from the sprinkler head 145 after passing through the two-way shunt pipe 146 and the mixing valve 1441. The water flow rate of the first water tank 141 and the second water tank 142 flowing into the sprinkler head 145 is adjusted by rotating the mixing valve 1441, thereby realizing the water temperature adjustment when the sprinkler head 145 sprays.

[0031] In an embodiment of the present utility model, the spray assembly 14 also includes a temperature sensor, a return valve 1442 and a return pipe 148. The temperature sensor is arranged on the spray pipe 144 to detect the water temperature in the spray pipe 144. The return valve 1442 is arranged between the temperature sensor and the return pipe 148 to connect or close the return pipe 148 according to the temperature sensor. The return pipe 148 is connected to the first water storage tank 141.

[0032] When the temperature sensor detects that the temperature of the water in the spray pipe 144 is higher or lower than the required temperature, the spray pipe 144 is closed by controlling the return valve 1442, and the return pipe 148 is connected at the same time, so that the water in the spray pipe 144 flows back from the return pipe 148 to the first water storage tank 141, so that the operator can adjust the water temperature in the first water storage tank 141 and the second water storage tank 142 according to the temperature detected by the temperature sensor. When the temperature sensor detects that the temperature of the water in the spray pipe 144 is equal to the required temperature, the return pipe 148 is closed by controlling the return valve 1442, and the spray pipe 144 is connected at the same time, so that the water in the spray pipe 144 is sprayed out from the spray head 145. At this time, the temperature of the sprayed water is the required spraying temperature.

[0033] In an embodiment of the present invention, the spray assembly 14 further includes a spray hose 147, which is disposed between the spray head 145 and the spray pipe 144 to adjust the spray angle of the spray head 145, thereby simulating the change in the spray angle during actual use.

[0034] In an embodiment of the present utility model, the spray head 145 includes an atomizing spray head 145 and a water spray head. The spray head 145 is detachably connected to the spray hose 147, so that the operator can flexibly replace the atomizing spray head 145 and the water spray head 145 to simulate different spraying modes in the actual use environment and improve the accuracy of the results of the simulated water resistance test.

[0035] In an embodiment of the present invention, a heater is provided in the first water tank 141 to heat the water in the first water tank 141 so that the spraying water temperature of the spray head 145 is higher when spraying, thereby simulating the mold water resistance test environment under high-temperature spraying. At the same time, the water in the first water tank 141 and the second water tank 142 can be mixed under the action of the mixing valve 1441, thereby realizing the adjustment of the spraying water temperature to simulate the mold water resistance test environment under different water temperatures.

[0036] In an embodiment of the present invention, a refrigerator is provided in the second water tank 142 to cool the water in the second water tank 142 so that the spraying water temperature of the spray head 145 is lower when spraying, thereby simulating the mold water resistance test environment under low-temperature spraying. At the same time, the water in the first water tank 141 and the second water tank 142 can be mixed under the action of the mixing valve 1441, thereby realizing the adjustment of the spraying water temperature to simulate the mold water resistance test environment under different water temperatures.

[0037] In an embodiment of the present invention, the spray assembly 14 further includes a solenoid valve 1443 and a relay. The solenoid valve 1443 is disposed in the spray pipe 144. The relay is electrically connected to the solenoid valve 1443 to control the solenoid valve 1443 to connect or close the spray pipe 144. When the relay controls the solenoid valve 1443 to connect the spray pipe 144, water in the spray pipe 144 can be sprayed out from the spray head 145. When the relay controls the solenoid valve 1443 to close the spray pipe 144, water in the spray pipe 144 can be retained in the spray pipe 144, thereby preventing the spray head 145 from spraying. The relay is a time relay, which controls the solenoid valve 1443 to connect or close the spray pipe 144 within a preset time, thereby simulating the cyclic spray environment during the mold water resistance test.
