Description

Technical Field

[0001] The present application relates to the technical field of ball valve detection, and in particular to a ball valve wear resistance detection device. Background Art

[0002] As we all know, valves are control elements in fluid delivery systems, with functions such as diversion, interception, and diversion. Ball valves have low flow resistance and rapid opening, and are recognized by domestic and foreign experts as the most promising replacement product. Wear-resistant ball valves use a special sealing structure, have reliable sealing performance, and truly achieve zero leakage.

[0003] During the production of wear-resistant ball valves, the inner wall of the sealing pair needs to be tested for wear resistance. Existing testing methods include surface topography, notch method, scratch test, etc. The scratch test is to slide sandpaper or grinding wheel on the coating surface of the inner wall of the ball valve, and judge the wear resistance of the coating by observing whether there are scratches on the coating or the size of the scratches; the observation method can be achieved by collecting pictures before and after the coating and comparing them with a computer.

[0004] In the prior art, reference may be made to the patent application publication number CN119375077A, which discloses a ball valve wear resistance detection device, including a conveyor, the conveyor including a bracket and a conveyor belt; a fixed plate is provided at the top of the conveyor and on one side of the conveyor belt, a hydraulic cylinder is provided on the side of the fixed plate away from the conveyor belt, the output end of the hydraulic cylinder passes through the fixed plate, and a receiving plate is provided at the end of the output end of the hydraulic cylinder; the ball valve wear resistance detection device described in the present invention is provided with a friction block and a camera. When in use, a turntable drives the friction block to rotate, and the friction block rotates inside the ball of the ball valve, generating friction with the inner wall of the ball valve ball, and the camera records the picture of the inner wall of the valve ball and uploads the picture to an external computer; the computer determines and records whether the current ball of the ball valve is qualified, and the conveyor drives the next ball valve on the conveyor belt to move to the detection position for continuous detection; such reciprocating can greatly improve the detection efficiency, and is suitable for the detection of large quantities of ball valves in actual production.

[0005] When the friction block is extended into the through hole of the ball valve, friction between the friction block and the coating of the through hole will generate a force on the ball valve. The ball valve is placed on a conveyor belt for transportation. The force will easily cause the ball valve to shift, resulting in deviations in subsequent test results. At the same time, the position of the ball valve is also easily offset during transportation on the conveyor belt, resulting in deviations between the sliding structure and the measured ball valve position, which will cause greater deviations in the subsequent test structure and reduce the accuracy of the wear resistance test of the ball valve. Summary of the invention

[0006] In order to improve the accuracy of ball valve wear resistance testing, the present application provides a ball valve wear resistance testing device.

[0007] The present application provides a ball valve wear resistance detection device, which adopts the following technical solution: A ball valve wear resistance detection device includes a frame, a conveyor belt arranged on the frame, a sliding structure, a detection structure and a rejection structure, and also includes a positioning structure for positioning the ball valve, the positioning structure includes: A positioning seat is arranged on the frame, and the positioning seat and the sliding structure are located on both sides of the conveyor belt; The positioning member is slidably arranged on the positioning seat in a direction close to or away from the conveyor belt, and the sliding direction is perpendicular to the direction in which the conveyor belt conveys the ball valve. The positioning member is provided with a positioning surface which is inclined and convenient for abutting against the through hole of the ball valve for positioning at one end close to the conveyor belt; The clamping assembly is arranged on the positioning seat; the positioning member is close to the conveyor belt and makes the positioning surface abut against the through hole for positioning and aligns the ball valve with the sliding structure, and at the same time, the positioning member moves to drive the clamping assembly to approach and clamp on the outer wall of the ball valve for positioning.

[0008] By adopting the above technical scheme, the manipulator places the ball valve to be tested on the conveyor belt for transportation, the ball valve is transported to the sliding structure and stops transportation, the positioning member approaches the ball valve, so that the positioning surface abuts against one end of the ball valve through hole to position the ball valve, and at the same time, when the positioning member moves, it drives the clamping assembly to approach the ball valve, so that the clamping assembly is clamped on the outer wall of the ball valve for positioning, so that the positioning surface and the clamping assembly can position the ball valve, the sliding structure starts to extend into the other end of the ball valve through hole, the sliding structure extends and rotates, so as to slide the through hole coating, and then the sliding structure shortens, stops rotating and moves to the outside of the ball valve, the detection structure photographs the coating inside the ball valve, and determines whether the wear resistance of the ball valve is qualified based on the scratches, and then the conveyor belt moves to transport the ball valve, and continues to detect the wear resistance of the next ball valve.

[0009] The ball valve can be positioned by the positioning piece and the clamping assembly so that the ball valve can be aligned with the sliding structure. Compared with positioning only by the inclined positioning surface, the risk of tilting when the positioning surface pushes the ball valve is reduced. At the same time, when the sliding structure starts to contact the coating, the ball valve can also be positioned, which greatly improves the accuracy of the ball valve wear resistance test.

[0010] Furthermore, the clamping assembly also pushes the ball valve closer to the positioning surface during the process of clamping the ball valve, further reducing the risk of the ball valve being far away from the positioning surface, improving the positioning accuracy, and improving the accuracy of precise measurement.

[0011] Optionally, a plurality of the clamping assemblies are arranged at intervals, and the clamping assemblies include: A clamping rod, one end of which is rotatably mounted on a positioning seat; A clamping plate, arranged on an end of the clamping rod away from the positioning seat; The connecting rod has two ends rotatably arranged on the clamping rod and the positioning member. When the positioning member approaches the ball valve, the connecting rod drives the clamping plate to approach the ball valve and makes the positioning surface abut against the through hole for positioning and makes the clamping plate press against the ball valve for positioning.

[0012] By adopting the above technical solution, when the positioning rod moves close to the ball valve, the positioning rod moves through the connecting rod to drive the clamping rod and the clamping plate to approach the ball valve, and the positioning surface abuts against one end of the through hole for positioning. At this time, the clamping assembly is also clamped on the outer wall of the ball valve for positioning, thereby realizing the positioning of the ball valve; when the positioning rod is away from the ball valve, the clamping rod and the clamping plate are away from the ball valve, so that the positioning rod, the clamping rod and the clamping plate are all located on the outside of the ball valve, and the conveyor belt starts to convey the ball valve, thereby reducing the risk of collision between the above structures and the ball valve and improving the accuracy during detection.

[0013] When the clamping plate clamps the ball valve, it also pushes the ball valve closer to the positioning surface, further reducing the risk of the ball valve being far away from the positioning surface, improving the positioning accuracy, and improving the accuracy of precision measurement.

[0014] Optionally, the sliding structure includes: A sliding seat is slidably arranged on the frame body in a direction close to or away from the ball valve, and the sliding seat and the positioning seat are located on both sides of the conveyor belt; A driving assembly, used for driving the sliding seat and the positioning rod to move closer to or away from the ball valve at the same time; The mounting rod is rotatably arranged on the side of the sliding seat close to the ball valve and the axis of the rotation direction coincides with the axis of the ball valve; A guide member is rotatably mounted on the mounting rod and is provided with an inclined guide surface, and the detection structure is arranged on the guide member; The telescopic component is arranged on the mounting rod and can be telescopic; the sliding seat and the positioning member are close to the ball valve and the positioning surface and the guide surface are against the two ends of the through hole for positioning, so that the telescopic component extends after extending to the inside of the ball valve, and the mounting rod rotates to drive the telescopic component to rotate.

[0015] By adopting the above technical solution, the sliding seat and the positioning rod are close to the ball valve at the same time, so that the guide surface and the positioning surface are simultaneously against the two ends of the through hole, and the clamping plate is also clamped on the outer wall of the ball valve for positioning, thereby further improving the positioning effect of the ball valve, and at the same time, the telescopic component is moved into the through hole, the telescopic component is started to approach the through hole coating, and the mounting rod rotates to drive the telescopic component to rotate, so as to slide the through hole coating. After the processing is completed, the telescopic component retracts away from the coating, and then the sliding seat and the positioning rod are simultaneously away from the ball valve, driving the guide part away from the ball valve, and then the detection structure is started to take pictures of the through hole coating. The photos are used to show the scratches on the coating, so as to realize the detection of the wear resistance of the ball valve.

[0016] The two ends of the ball valve are positioned by cooperating with the guide member, the positioning rod and the clamping assembly at the same time, thereby further improving the positioning accuracy and effect of the ball valve, and further improving the accuracy of the wear resistance detection of the ball valve; at the same time, after the guide surface is separated from the ball valve, light can enter the through hole, and then the detection structure can take a picture of the coating. At this time, the ball valve is in a stopped state, and the telescopic assembly has retracted, and will not block the coating, thereby improving the display effect of scratches on the coating, making subsequent judgment results more accurate, and further improving the accuracy of the wear resistance detection of the ball valve.

[0017] Optionally, the telescopic component includes: A fixing rod, arranged on an end of the mounting rod away from the sliding seat; A telescopic rod, the telescopic rod is slidably arranged on the fixed rod in a direction approaching or moving away from the through-hole coating; The telescopic member is used to drive the telescopic rod to move.

[0018] By adopting the above technical solution, the installation rod drives the telescopic assembly to move into the ball valve, the telescopic part drives the telescopic rod close to the coating, and then the installation rod rotates to drive the telescopic rod to rotate, so as to slide the coating. After the processing is completed, the telescopic part drives the telescopic rod away from the coating.

[0019] Optionally, the positioning member includes a positioning rod slidably mounted on the positioning seat and a positioning head detachably arranged on the positioning rod, the connecting rod is rotatably connected to the positioning rod, and the positioning surface is located on the positioning head; a rotating ring is rotatably mounted on the mounting rod, and the guide member is detachably mounted on the rotating ring.

[0021] Optionally, the driving component includes: The driving member 1 and the driving member 2 are respectively connected to the positioning member and the sliding seat and are used to drive the positioning rod and the sliding seat to move closer to or away from the ball valve at the same time.

When the sliding seat approaches the ball valve, the lifting assembly is driven to extend under the ball valve. The lifting assembly is started to transport the unqualified ball valves to the collecting assembly.

[0024] By adopting the above technical solution, the conveyor belt conveys the ball valves. When one of the ball valves is aligned with the sliding structure, the next ball valve, that is, the ball valve that has been tested, is moved to be aligned with the lifting assembly. During the conveying process of the ball valves, the detection structure determines whether the ball valves are qualified based on the detection results.

[0025] When the sliding seat is close to the ball valve, the rejection seat and the lifting assembly are driven close to the ball valve, so that the lifting assembly extends to the bottom of the ball valve after inspection. If the ball valve is qualified, the lifting assembly will not start; on the contrary, if the ball valve is unqualified, when the sliding structure starts to slide, the lifting assembly starts to transport the ball valve to the collection assembly for transportation and collection. The time spent by the lifting assembly is less than the running time of the sliding structure. When the sliding structure completes the sliding process, the sliding seat, the rejection seat and the lifting assembly are away from the ball valve, and then the conveyor belt starts to continue to transport the ball valve, the lifting assembly rotates to its original position, and then the process is repeated to reject the unqualified ball valve. At the same time, the lifting assembly and the sliding structure are carried out at the same time, which greatly shortens the time spent on inspection and improves the inspection efficiency.

[0026] Optionally, the collection component includes: A collecting plate is arranged on the frame and tilted downward; A conveyor belt is arranged on the frame; A plurality of guide rollers are rotatably mounted on the collecting plate and are used to convey unqualified ball valves to the conveyor belt for transport.

[0029] By adopting the above technical solution, the rotating part drives the rejection rod and multiple lifting plates to move simultaneously, the multiple lifting plates move upward and rotate, and after the multiple lifting plates are supported on the lower surface of the ball valve, the ball valve is driven to move upward and rotate, and then move downward and rotate, so that the ball valve is placed from the conveyor belt to the collection assembly, the ball valve is transported and moved on the collection assembly, and then the rejection seat moves away from the ball valve, and then the rotating part drives the multiple lifting plates to rotate, so that the multiple lifting plates are located on the outside of the ball valve, thereby realizing the conveyance and placement of unqualified ball valves on the collection assembly for collection.

[0030] Optionally, the lifting plate is provided with a buffer layer for buffering.

[0031] By adopting the above technical solution, the risk of damaging the ball valve when the lifting piece contacts the ball valve is reduced.

[0032] In summary, the present application includes at least one of the following beneficial technical effects: 1. The ball valve can be positioned by the positioning piece and the clamping assembly so that the ball valve can be aligned with the sliding structure. Compared with positioning only by the inclined positioning surface, the risk of tilting when the positioning surface pushes the ball valve is reduced.

[0033] 2. The two ends of the ball valve are positioned by cooperating with the guide, the positioning rod and the clamping assembly at the same time, thereby further improving the positioning accuracy and effect of the ball valve, and further improving the accuracy of the wear resistance detection of the ball valve; at the same time, after the guide surface is separated from the ball valve, light can enter the through hole, and then the detection structure can take a picture of the coating. At this time, the ball valve is in a stopped state, and the telescopic assembly has retracted, and will not block the coating, thereby improving the display effect of scratches on the coating, making the subsequent judgment results more accurate, and further improving the accuracy of the wear resistance detection of the ball valve.
