Description

Technical Field

[0002] With the rapid development of my country's petrochemical, coal chemical, silicon chemical, mining and metallurgy, power and environmental protection industries, fluid working conditions are becoming increasingly complex and demanding, which puts higher requirements on valve performance. Ceramic ball valves have gradually replaced traditional metal ball valves and become the first choice in many industrial fields due to their excellent wear resistance, corrosion resistance and excellent performance in high temperature, high pressure and highly corrosive media. However, the special properties of ceramic materials, such as high hardness, brittleness and the complexity of internal microstructure, also bring new technical challenges. Among them, the instability of the limit torque of the ceramic ball core is particularly prominent, which directly affects the service life of the valve.

[0003] Internal microcracks, residual stress or material unevenness that may exist in the ceramic ball core during the manufacturing process will lead to inconsistent mechanical properties, which in turn affects the overall reliability of the valve. If these defective ball cores flow into the valve assembly process, they will cause valve failure in subsequent use and even cause serious safety accidents. Therefore, accurate testing of the torque performance of the ceramic ball core before valve assembly has become a key link in ensuring valve quality.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] The following first describes the concepts involved in the present application in conjunction with the accompanying drawings. It should be noted that the following description of each concept is only to make the content of the present application easier to understand, and does not limit the scope of protection of the present application; at the same time, the embodiments and features in the embodiments of the present application can be combined with each other in the absence of conflict. The present application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments. Example

[0019] like Figures 1 to 8As shown, the present invention provides a ceramic ball core torque detection device, including a frame 1, a avoidance groove 11 is opened on the top of the frame 1, a torque detection component 2 and a top support assembly 3 are fixedly installed on both sides of the top of the frame 1 close to the avoidance groove 11, a lifting support 4 is slidably installed at the bottom of the frame 1, and the top of the lifting support 4 extends out from the avoidance groove 11, a ball core 5 to be tested is placed in the lifting support 4, an expansion sleeve 6 is fixedly installed in the ball core 5 to be tested, a limit assembly 7 for limiting the ball core 5 to be tested is fixedly installed on the top of the frame 1, a cross plate 12 is fixedly installed on the top of the frame 1, an adjustment assembly 8 for adjusting the posture of the ball core 5 to be tested is fixedly installed on the top of the cross plate 12, and a blanking assembly 9 is fixedly installed at the bottom of the frame 1.

[0020] As a further illustration of the embodiments of the present invention, the internal microcracks, residual stress or material unevenness that may exist in the ceramic ball core during the manufacturing process will lead to inconsistent mechanical properties, thereby affecting the overall reliability of the valve. If these defective ball cores flow into the valve assembly process, they will cause valve failure in subsequent use, and even cause serious safety accidents. The complete detection process of the device is as follows: first, a standard ball core 5 to be tested needs to be placed from the top of the lifting support 4, and the ball core 5 to be tested is transported from the top to the bottom through the lifting support 4. During the transportation process, the ball core 5 to be tested first reaches the working area of ​​the adjustment component 8, and the ball core 5 to be tested is adjusted to a specific posture through the adjustment component 8, so that the subsequent components can detect and limit the ball core 5 to be tested. After the adjustment is completed, the lifting support 4 continues to descend to the working area of ​​the torque detection component 2, and the top support component 3 is started to move the lifting support 4 closer to the space where the torque detection component 2 is located, until the output end of the torque detection component 2 extends into the ball core 5 to be tested, and then the limit component 7 is started, and the output end of the limit component 7 extends into the expansion sleeve 6, so that the expansion sleeve 6 is deformed, thereby fixing the ball core 5 to be tested, and then the torque detection component 2 is started until the output end of the torque detection component 2 damages the standard ball core 5 to be tested, so as to measure the limit torque of the ball core 5 to be tested and record the value, and calculate the corresponding test value according to the torque calculated according to the limit torque, and use the value as the qualified torque value of the subsequent ball core 5 to be tested. Then, the torque detection component 2, the top support component 3 and the limit component 7 are reset to avoid interference with the ceramic ball core, and then the ceramic ball core is driven to descend to the bottom by the lifting support 4, and the ceramic ball core is removed from the lifting support 4 by the unloading component 9 to complete the calibration of the device, and then the above process is repeated to realize the continuous torque detection operation of multiple ceramic ball cores by the device.

[0021] As a preferred solution provided by a ceramic ball core torque detection device, the torque detection component 2 includes a bracket 21 fixedly installed on the top of the frame 1, a first motor 22 is fixedly installed on the bottom of the bracket 21, a first torque sensor 23 is fixedly installed on the top of the bracket 21, a first connecting rod 231 is installed at one end of the first torque sensor 23, and a torsion rod 25 is installed at the other end of the first torque sensor 23, one end of the first connecting rod 231 and the output end of the first motor 22 are fixedly connected with a first synchronous wheel 24, and the two first synchronous wheels 24 are linked by a synchronous belt.

[0022] As a further illustration of the embodiment of the present invention, in this embodiment, after the first torque sensor 23 records the limit torque value of the ball core 5 to be tested, when performing subsequent torque detection, when the first torque sensor 23 detects that the first connecting rod 231 reaches the previously recorded limit torque value, the first motor 22 automatically stops running, and the torque value applied by the torsion rod 25 at this time is the limit torque of the ball core 5 to be tested. If the ball core 5 to be tested is not damaged by the torsion resistance of the torsion rod 25, it is qualified, otherwise it is defective. Specifically, during the detection process, the side wall of the ball core 5 to be tested is provided with a slot for the torsion rod 25 to enter, and the end of the torsion rod 25 is inserted into the slot and fits with the inner wall of the slot of the ball core 5 to be tested. When the torsion rod 25 rotates, the end of the torsion rod 25 resists the inner wall of the ball core 5 to be tested to test the limit torque of the ball core 5 to be tested.

[0023] As a preferred solution provided by a ceramic ball core torque detection device, the limit assembly 7 includes a screw slide 71 fixedly mounted on the top of the frame 1, and a bidirectional screw 72 connected to the frame 1 is rotatably provided on one side of the screw slide 71, and a limit seat 73 is fixedly mounted on the top of both ends of the screw slide 71, and a top support head 74 is fixedly mounted on the side wall of the limit seat 73, and a second motor 75 and a second torque sensor 76 are fixedly mounted on the top of the frame 1, a second connecting rod 761 is mounted on one end of the second torque sensor 76, and the other end of the second torque sensor 76 is connected to the output end of the second motor 75, and a second synchronous wheel 77 is fixedly connected to one end of the second connecting rod 761 and the end of the bidirectional screw 72, and the two second synchronous wheels 77 are linked by a synchronous belt, and the second motor 75 drives the screw slide 71 to drive the two top support heads 74 to move closer to or away from each other.

[0024] As a further illustration of the embodiment of the present invention, in this embodiment, the bidirectional screw 72 of the limit assembly 7 is driven by the second motor 75 and linked with the synchronous belt through the second synchronous wheel 77, so that the limit seats 73 at both ends are close to each other. The top support head 74 moves with the limit seat 73 and extends into the expansion sleeve 6, and the expansion sleeve 6 is expanded evenly by symmetrical force, thereby fixing the ball core 5 to be tested. The second torque sensor 76 monitors the driving torque of the bidirectional screw 72 in real time to prevent the expansion sleeve 6 or the ball core from being damaged by excessive top support force. Through bidirectional limit and torque feedback control, the deformation of the expansion sleeve 6 is controlled to avoid deflection of the ball core or stress concentration due to unilateral force.

[0025] As a preferred solution provided by a ceramic ball core torque detection device, the lifting support 4 includes two bracket plates 411, the two bracket plates 411 are fixedly connected by multiple support rods 412, and a screw 413 is rotatably connected between the two bracket plates 411, a lifting plate 41 is threadedly installed on the screw 413, and the lifting plate 41 is slidably connected to the multiple support rods 412, wherein a third motor 42 for driving the lifting plate 41 to rise and fall is provided on the top of the upper bracket plate 411, a ball core support 43 for limiting the ball core 5 to be tested is fixedly installed on the lifting plate 41, and a vertical plate 44 for cooperating with the top support assembly 3 is fixedly installed on one side of the lifting plate 41.

[0026] As a further explanation of the embodiment of the present invention, in this embodiment, the ball core support 43 adopts an arc-shaped groove structure, which fits with the outer surface of the ball core 5 to be tested to prevent the ball core 5 to be tested from rolling during the lifting process. In addition, the ball core 5 to be tested is restricted in the ball core support 43, which is convenient for the adjustment component 8 to adjust the posture of the ball core 5 to be tested. The ceramic ball core in the conventional automatic valve on the market has a through hole in the side wall for the output end of the ball valve controller to enter. The vertical plate 44 cooperates with the top support component 3 to achieve the horizontal displacement fine adjustment of the lifting support 4, ensuring that the torsion rod 25 extends into the ball core 5 to be tested along the opening of the side wall of the ball core 5 to be tested. The torsion rod 25 is inserted into the opening of the side wall of the ball core 5 to be tested and twisted to perform a torque test on the ball core 5 to be tested.

[0027] As a preferred solution provided by a ceramic ball core torque detection device, the unloading assembly 9 includes a first cylinder 91 fixedly installed on the bottom of the frame 1, a protrusion 92 is formed on the bracket plate 411 at the bottom of the lifting support 4, an opening is provided on the lifting plate 41 for the protrusion 92 to pass through, and a slide 93 for guiding the rolling direction of the ball core 5 to be tested is fixedly installed on one side of the bottom of the lifting support 4.

[0028] As a further explanation of the embodiment of the present invention, in this embodiment, after the test is completed, when the third motor 42 drives the lifting plate 41 to drive the ball core 5 to be tested to move downward to the bottom of the lifting support 4, the protrusion 92 located at the bottom of the lifting support 4 pushes the ball core 5 to be tested upward along the opening, so that the ball core 5 to be tested is separated from the ball core support 43, and the first cylinder 91 is started at this time, and the side wall of the ball core 5 to be tested is pushed up by the output end of the first cylinder 91, so that the ball core 5 to be tested rolls out along the slide 93. The slide 93 has an inclined angle and a smooth surface, which ensures that the ball core slides to the designated area without collision, avoids surface scratches that may be caused by traditional pneumatic clamps, and is particularly suitable for non-destructive feeding of brittle ceramic materials.

[0029] As a preferred solution provided by a ceramic ball core torque detection device, a cross bar 13 and two guide rods 14 are fixedly installed at the bottom of the frame 1, and the cross bar 13 and the two guide rods 14 both pass through the bottom of the lifting support 4, and a spring 15 is sleeved on the cross bar 13, and the two ends of the spring 15 are respectively pressed against the side walls of the bottom of the frame 1 and the side walls of the bottom of the lifting support 4.

[0030] As a further explanation of the embodiment of the present invention, in this embodiment, the cross bar 13 and the guide bar 14 constitute the sliding track of the lifting support 4, and the lifting support 4 is kept away from the torsion bar 25 by the spring 15, so as to prevent the torsion bar 25 from interfering with the travel path of the lifting plate 41. Only by the top support assembly 3 cooperating with the vertical plate 44, the lifting support 4 is pushed toward the torsion bar 25, ensuring that the torsion bar 25 can contact the ball core 5 to be tested only during torque detection.

[0031] As a preferred solution provided by a ceramic ball core torque detection device, the adjustment component 8 includes a plurality of mounting seats 81 fixedly mounted on the top of a cross-plate 12, a travel groove 121 for the lifting support 4 to pass through is opened on the top of the cross-plate 12, and a plurality of mounting seats 81 are distributed along the outer periphery of the travel groove 121, and a second cylinder 82 is fixedly mounted on the side wall of each mounting seat 81, and an output end of the second cylinder 82 passes through the side wall of the mounting seat 81 and is fixedly connected to an opening plate 83, and an adjusting wheel 84 is rotatably mounted in each opening plate 83, and all relative adjusting wheels 84 are arranged perpendicular to each other, and a fourth motor 85 for driving the adjusting wheel 84 to rotate is fixedly mounted on the top of the opening plate 83.

[0032] As a further explanation of the embodiment of the present invention, in this embodiment, the second cylinder 82 of the adjustment assembly 8 drives the opening plate 83 to move horizontally, so that the adjustment wheel 84 contacts the outer surface of the ball core 5 to be tested, and the ball core 5 to be tested is also restricted by the ball core support 43, and will not be displaced due to the interference of the adjustment wheel 84. The fourth motor 85 drives the adjustment wheel 84 to rotate, and the circumferential angle of the ball core 5 to be tested is adjusted by the friction between the adjustment wheel 84 and the ball core 5 to be tested, wherein two sets of relative adjustment wheels 84 are arranged perpendicular to each other, and when the adjustment wheel 84 on one side rotates the ball core 5 to be tested, the adjustment wheel 84 on the other side can make up for the rotation restriction of the adjustment wheel 84 on one side, so that the adjustment assembly 8 has more correction angles. The mounting seat 81 is evenly distributed along the circumference of the running groove 121 to realize the posture correction of the ball core 5 to be tested in multiple degrees of freedom. Through multi-directional coordinated adjustment, it is ensured that the installation posture of the ball core 5 to be tested is strictly aligned with the force direction of the torque detection component 2, and the detection error caused by angle deviation is reduced. In addition, a monitor (not shown in the figure) is provided on the top of the mounting seat 81. Through multi-directional monitoring by the monitors at various angles, the initial posture of the ball core 5 to be tested that enters the adjustment component 8 is scanned and uploaded to an external intelligent device for analysis. Corresponding instructions are issued to the fourth motor 85 and the second cylinder 82 through manual or intelligent equipment to ensure that the ball core 5 to be tested can enter the work station where the torque detection component 2 is located in a specific posture. Specifically, the flow direction of the flow channel in the ball core 5 to be tested is adjusted to be aligned with the top support head 74 through the adjustment component 8, and the perforation on the side wall of the ball core 5 to be tested is aligned with the torsion rod 25, which is a specific posture.

[0033] As a preferred solution provided by a ceramic ball core torque detection device, the top support assembly 3 includes a right-angle seat 31 fixedly installed on the top of the frame 1, and a third cylinder 32 is fixedly installed on the side wall of the right-angle seat 31. The output end of the third cylinder 32 passes through the side wall of the right-angle seat 31 and is fixedly connected to a top support disc 33.

[0034] As a further illustration of an embodiment of the present invention, in this embodiment, the vertical support surface of the right-angle seat 31 provides a stable support force to ensure that the support force of the support disc 33 is transmitted in the horizontal direction, thereby preventing the lifting support 4 from tilting during the movement.
