Description

Technical Field

[0001] The present invention relates to the technical field of new material rolling oil detection, and particularly to a viscosity detection device for new material rolling oil. Background Technique

[0002] Rolling oil is a lubricating and cooling medium used in metal rolling processes, mainly used to reduce the friction between the rolling mill rolls and the metal sheet, while controlling the temperature, preventing oxidation, and extending the equipment life. New material rolling oil is an upgraded product based on traditional formulations. During the research and development of new material rolling oil, it is necessary to detect its viscosity.

[0003] Currently, when detecting the viscosity of new material rolling oil, the sample needs to be added into a capillary viscometer, and then water-bath heated. After reaching a constant temperature, a syringe is used to draw air from one end of the capillary to make the liquid move to a specified height, and then the connection is disconnected to keep the end of the capillary unobstructed. By measuring the time required for a certain volume of oil sample to pass through the capillary under the action of gravity, the kinematic viscosity is calculated. However, during operation, in order to reduce errors, multiple detections are required and the average value is taken. Therefore, it is necessary to frequently connect the end of the capillary to the syringe, manually draw air, and then disconnect the connection, resulting in a cumbersome operation.

[0007] Furthermore, a clamping seat is placed on the top of the top cover, a capillary viscometer is passed through the interior of the clamping seat, and a connecting component is provided on the outside of the clamping seat.

[0008] Furthermore, the connecting assembly includes a boss, the bottom outer end of the clamp seat is provided with a boss, and the boss is engaged with the top cover, one end of the clamp seat is internally threaded with a screw, and the end of the screw is rotatably connected to an anti-slip clamp, and the anti-slip clamp is slidably connected to the clamp seat.

[0009] Furthermore, a bracket is fixed on the top of the clamp seat, and the upper end of the bracket is hollow. The middle of the bracket is slidably connected to a sliding tube, and a rubber sleeve is fixed to the bottom of the sliding tube. The opening of the rubber sleeve is trumpet-shaped, and a compression spring is connected to the top of the rubber sleeve, and the compression spring is in contact with the bracket.

[0010] Furthermore, a plug-in tube is fixed to one side of the bracket, and the plug-in tube is in a right-angle shape, and the end of the plug-in tube is slidably connected to the socket.

[0011] Furthermore, the interior of the socket is communicated with the interior of the three-way valve, and the socket is fixedly connected to the top cover.

[0012] Furthermore, a switching assembly is provided on the top of the top cover, and the switching assembly includes a slide groove.

[0013] Furthermore, a guide groove is provided at the end of the adjustment plate, and a sliding column is slidably connected inside the guide groove, and a driving plate is fixed on the top of the sliding column.

[0015] The new material rolling oil viscosity detection device provided by the present invention has the following beneficial effects: 1. The present invention can synchronously complete the switching of the three-way valve and the linkage of the suction mechanism through the simple operation of pushing and pulling the adjustment plate. During the process of pushing the adjustment plate, the engagement of the toothed plate and the adjustment gear drives the valve stem to rotate, enabling the three-way valve to connect the capillary viscometer and the suction pipeline. At the same time, the reducer reduces the speed and increases the torque to drive the piston to reciprocate to form a stable negative pressure, and the cooperation of the two check valve designs realizes continuous suction. And when the adjustment plate is pulled back, the three-way valve automatically resets to connect to the atmosphere. The whole process does not require additional operating devices, which not only significantly simplifies the cumbersome process of repeatedly switching the air extraction equipment in traditional detection, but also precisely controls the suction rate through the reducer to ensure that the oil smoothly enters the measuring ball, effectively avoiding the influence of flow fluctuations on the detection accuracy, and realizing the combination of one-key operation and precise control.

[0016] 2. The switching component of the present invention adopts a composite design of chute guidance and mechanical interlock. The combination of the chute and the slider ensures the stability of the linear movement of the adjustment plate. The guide groove drives the axial movement of the drive plate through the sliding column, enabling the engagement sleeve to form a reliable engagement with the driving shaft. The bevel angle design at the tooth end effectively eliminates the docking impact. When the adjustment plate is pushed to the working position, the transmission system automatically engages and drives the piston rod to operate. After the operation is completed, the engagement sleeve automatically disengages from the transmission shaft, realizing the automatic start and stop of power transmission. This mechanical interlock mechanism not only ensures the reliability of power transmission during the operation of the equipment, but also automatically cuts off the power load in the non-working state, prolonging the service life of key components.

[0017] 3. When clamping, the present invention realizes quick clamping through the coordinated action of threaded clamping and elastic sealing. Rotating the screw drives the anti-slip clamp block to fix the viscometer body, and the compression spring pushes the rubber sleeve to automatically fit the thin tube to form a reliable seal. The positioning design of the convex column ensures the precise docking of the insertion pipe. Compared with the traditional detection that requires separate processing of multiple processes such as fixture fixing and pipeline connection, this design realizes the synchronous completion of clamping positioning and pipeline connection, greatly shortening the detection preparation time.

[0020] Please refer to Figures 1 to 4 , the viscosity detection device for the new material rolling oil provided by the present invention includes a heating base 1 and a suction component 11. A water bath cylinder 2 is arranged on the top of the heating base 1, and a top cover 3 is arranged on the top of the water bath cylinder 2. A clamping seat 4 is arranged on the top of the top cover 3, and a capillary viscometer 5 penetrates through the inside of the clamping seat 4. A connection component 6 is arranged outside the clamping seat 4. The connection component 6 includes a convex column 601. The convex column 601 is arranged at the outer end of the bottom of the clamping seat 4 and is embedded with the top cover 3. One end inside the clamping seat 4 is threadedly connected with a screw 602, and the end of the screw 602 is rotatably connected with an anti-slip clamping block 603, and the anti-slip clamping block 603 is slidably connected with the clamping seat 4. A bracket 604 is fixed on the top of the clamping seat 4, and the upper end inside the bracket 604 is hollow. A sliding tube 605 is slidably connected to the middle of the bracket 604, and a rubber sleeve 606 is fixed to the bottom of the sliding tube 605. The opening of the rubber sleeve 606 is in a flared shape, and the top of the rubber sleeve 606 is connected with a compression spring 607, and the compression spring 607 abuts against the bracket 604. An insertion connecting tube 608 is fixed on one side of the bracket 604, and the insertion connecting tube 608 is in a right-angled shape, and the end of the insertion connecting tube 608 is slidably connected with an insertion socket 609.

[0021] The specific operation is as follows. When installing the capillary viscometer 5, first insert it into the hole of the clamping seat 4, and then rotate the screw rod 602, so that the anti-slip clamping block 603 moves towards the side of the capillary viscometer 5 to fix it. During this process, the compression spring 607 will push the rubber sleeve 606 to fit with the upper end of the thin tube of the capillary viscometer 5, automatically sealingly connecting with the upper end of the thin tube of the capillary viscometer 5, so that the inside of the thin tube of the capillary viscometer 5 is communicated with the inside of the bracket 604. Then, when the capillary viscometer 5 is inserted into the water bath cylinder 2 from the opening on the top cover 3, the convex column 601 and the matching groove on the top of the top cover 3 are used to limit the clamping seat 4 to prevent the insertion pipe 608 from deflecting from the socket 609. And after placing, the insertion pipe 608 will just be docked with the socket 609. Therefore, during the clamping and placing of the capillary viscometer 5, the thin tube of the capillary viscometer 5 is automatically communicated with the pipeline on the detection device, thus reducing extra operation steps and being very convenient.

[0022] Please refer to Figures 3 to 5 , a motor 7 is fixed on the top of the top cover 3, and the output shaft of the motor 7 is connected with a driving gear 8. One side of the driving gear 8 is engaged with a driven gear 9, and a stirring shaft 10 is arranged inside the driven gear 9. The suction assembly 11 is arranged on one side of the driven gear 9.

[0023] In some embodiments, the suction assembly 11 includes a driving gear 1101. One side of the driven gear 9 is engaged with the driving gear 1101, and one end of the driving gear 1101 is connected with a speed reducer 1102. The output end of the speed reducer 1102 is connected with a driving shaft 1103, and one end of the driving shaft 1103 is rotatably connected with a driven shaft 1104. A rotating disc 1105 is fixed at the end of the driven shaft 1104, and one side of the rotating disc 1105 is rotatably connected with a connecting rod 1106. The end of the connecting rod 1106 is rotatably connected with a piston rod 1107, and the outer side of one end of the piston rod 1107 is slidably connected with a fixed cylinder 1108. A one-way valve 1109 is arranged on the outer peripheral surface of the fixed cylinder 1108, and the one-way valve 1109 located in the upper part of the fixed cylinder 1108 is connected with a manifold pipe 1110. The end of the manifold pipe 1110 is provided with a three-way valve 1111, and the valve core of the three-way valve 1111 is connected with a valve rod 1112. The inside of the socket 609 is communicated with the inside of the three-way valve 1111, and the socket 609 is fixedly connected with the top cover 3. The lower end of the valve rod 1112 is provided with an adjusting gear 1113, and one side of the adjusting gear 1113 is engaged with a toothed plate 1114. One side of the toothed plate 1114 is fixed with an adjusting plate 1115. The top cover 3 is rotatably connected with the valve rod 1112, and the top cover 3 is fixedly connected with the fixed cylinder 1108.

[0024] During the detection process, when moving the oil in the capillary viscometer 5 into the measuring ball, only need to push the adjusting plate 1115. At this time, the toothed plate 1114 will drive the valve rod 1112 to rotate through the adjusting gear 1113, and the communication state inside the three-way valve 1111 can be switched, so that the inside of the thin tube of the capillary viscometer 5 is connected to the inside of the manifold 1110. At this time, when the motor 7 drives the stirring shaft 10 to stir the inside of the water bath cylinder 2 through the driving gear 8 and the driven gear 9, it can also drive the rotating disc 1105 to rotate through the driving gear 1101, the reducer 1102, the driving shaft 1103 and the driven shaft 1104, so that the connecting rod 1106 can reciprocally push and pull the piston rod 1107, thereby changing the air pressure on both sides inside the fixed cylinder 1108. At the same time, the check valves 1109 located on the upper and side parts of the fixed cylinder 1108 allow the air flow to flow in opposite directions. Therefore, when the air pressure inside the fixed cylinder 1108 decreases, the inside of the capillary viscometer 5 can be evacuated through the manifold 1110, and the oil can be automatically sucked into the measuring ball; It should be noted that when the air pressure at the other end inside the fixed cylinder 1108 becomes higher, it can be discharged through the check valve 1109 on the side. And there are two groups of check valves 1109, so that the piston rod 1107 can perform the suction operation during the reciprocating motion, maintaining the continuity of liquid suction. At the same time, by using the deceleration performance of the reducer 1102, while increasing the torque, the suction speed can be slowed down, so as to facilitate the control of the flow rate of the rolling oil.

[0025] And when the oil moves to the designated position, pulling the adjusting plate 1115 can make the toothed plate 1114 drive the adjusting gear 1113 to rotate, so that the spool inside the three-way valve 1111 resets. At this time, the upper end inside the measuring ball of the capillary viscometer 5 will be connected to the atmosphere through the empty joint of the three-way valve 1111, and normal measurement operations can be carried out. Because during the use process, only need to push and pull the adjusting plate 1115, there is no need to frequently use additional devices to evacuate and disconnect the capillary viscometer 5, thereby improving the detection efficiency.

[0026] Please refer to Figure 3 and Figure 6, a switching component 12 is provided on the top of the top cover 3, and the switching component 12 includes a chute 1201. A chute 1201 is opened on the top of the top cover 3, and a slider 1202 is slidably connected inside the chute 1201. The cross-section of the slider 1202 is an isosceles trapezoid, and the slider 1202 is fixedly connected to the adjusting plate 1115. A guiding groove 1203 is opened at the end of the adjusting plate 1115, and a sliding column 1204 is slidably connected inside the guiding groove 1203. And a driving plate 1205 is fixed at the top of the sliding column 1204. A guiding rod 1206 is slidably connected to the middle of the driving plate 1205, and the guiding rod 1206 is fixedly connected to the speed reducer 1102. A engaging gear sleeve 1207 is rotatably connected inside the upper end of the guiding rod 1206. Tooth grooves 1208 are opened on the outer sides of the driving shaft 1103 and the driven shaft 1104, and the tooth grooves 1208 are matched with the engaging gear sleeve 1207.

[0027] During the process of pushing the adjusting plate 1115, the chute 1201 and the slider 1202 will guide the adjusting plate 1115 to ensure its stability during the moving process. At the same time, the sliding column 1204 is forced through the guiding groove 1203, so that the driving plate 1205 moves along the axial direction of the guiding rod 1206 towards the speed reducer 1102, which can drive the engaging gear sleeve 1207 to slide to the end of the driving shaft 1103 to connect the driving shaft 1103 and the driven shaft 1104, enabling them to perform normal transmission operations, facilitating the automatic evacuation of the inside of the capillary viscometer 5. At the same time, since the rotational speed of the driving shaft 1103 is relatively low and the end of the tooth groove 1208 is provided with an inclined guiding portion, the docking is very convenient and the situation of jamming is avoided. When pushing the adjusting plate 1115 to connect the capillary viscometer 5 with the external atmosphere, the guiding groove 1203 will drive the sliding column 1204 to move back and reset, so that the engaging gear sleeve 1207 is separated from the driving shaft 1103. At this time, the transmission connection between the driving shaft 1103 and the driven shaft 1104 can be disconnected, thereby automatically stopping the suction operation, reducing the equipment load and saving energy consumption when not in use.

[0028] When using the new material rolling oil viscosity detection device of the present application, first insert the capillary viscometer 5 into the hole of the clamping seat 4, and then rotate the screw rod 602, the anti-slip clamping block 603 can be moved towards the side of the capillary viscometer 5 to fix it. At the same time, the compression spring 607 will push the rubber sleeve 606 to make it fit with the upper end of the thin tube of the capillary viscometer 5, and automatically seal and connect with the upper end of the thin tube of the capillary viscometer 5, so that the inside of the thin tube of the capillary viscometer 5 is communicated with the inside of the support 604; Secondly, insert the capillary viscometer 5 into the interior of the water bath cylinder 2 through the opening on the top cover 3. At this time, use the convex column 601 and the matching groove on the top of the top cover 3 to limit the clamping seat 4, avoiding the deflection of the insertion pipe 608 and the insertion socket 609. And after placement, the insertion pipe 608 will just be docked with the insertion socket 609. Therefore, during the clamping and placement of the capillary viscometer 5, the capillary of the capillary viscometer 5 is automatically connected to the pipeline on the detection device; Next, use a pipette to inject the rolling oil sample into the flat liquid storage area from the thick tube of the capillary viscometer 5, and then start the heating seat 1 to heat the water bath cylinder 2. At this time, the motor 7 drives the stirring shaft 10 to stir the interior of the water bath cylinder 2 through the driving gear 8 and the driven gear 9, so that the capillary viscometer 5 is evenly heated. And after the rolling oil sample is heated to the specified temperature, push the adjusting plate 1115. At this time, the toothed plate 1114 will drive the valve rod 1112 to rotate through the adjusting gear 1113, and the communication state inside the three-way valve 1111 can be switched, so that the interior of the thin tube of the capillary viscometer 5 is connected to the interior of the manifold 1110. During this process, the chute 1201 and the slider 1202 will guide the adjusting plate 1115 to ensure the stability of its movement. At the same time, the sliding column 1204 is forced through the guiding groove 1203, so that the driving plate 1205 moves along the axial direction of the guiding rod 1206 towards the speed reducer 1102, and the engaging sleeve 1207 can be driven to slide to the end of the driving shaft 1103 to connect the driving shaft 1103 and the driven shaft 1104, enabling normal transmission operation; Then, the driven gear 9 will drive the rotating disk 1105 to rotate through the driving gear 1101, the speed reducer 1102, the driving shaft 1103 and the driven shaft 1104, so that the connecting rod 1106 reciprocally pushes and pulls the piston rod 1107, thereby changing the air pressure on both sides inside the fixed cylinder 1108. At the same time, the one-way valves 1109 located on the upper and side parts of the fixed cylinder 1108 allow the air flow to flow in opposite directions. Therefore, when the air pressure inside the fixed cylinder 1108 decreases, the interior of the capillary viscometer 5 can be evacuated through the manifold 1110, and the oil can be automatically sucked into the measuring ball. And when the air pressure at the other end inside the fixed cylinder 1108 becomes higher, it can be discharged through the one-way valve 1109 on the side. And there are two groups of one-way valves 1109, so that the piston rod 1107 can perform the suction operation during reciprocating motion, maintaining the continuity of liquid suction. At the same time, using the deceleration performance of the speed reducer 1102, while increasing the torque, the suction speed can be slowed down, thus facilitating the control of the flow rate of the rolling oil; Then, after the oil fluid moves to the specified position, pulling the adjusting plate 1115 can drive the toothed plate 1114 to drive the adjusting gear 1113 to rotate, so that the valve core inside the three-way valve 1111 resets. At this time, the upper part inside the measuring ball of the capillary viscometer 5 will be connected to the atmosphere through the empty joint of the three-way valve 1111, and normal measurement operations can be carried out. At the same time, the guide groove 1203 will drive the sliding column 1204 to move back and reset, so that the engaging gear sleeve 1207 is separated from the driving shaft 1103. At this time, the transmission connection between the driving shaft 1103 and the driven shaft 1104 can be disconnected, thus automatically stopping the suction operation; Finally, use a stopwatch to record the time consumed for the rolling oil to move to the specified distance to calculate the viscosity. And when taking the average value after multiple measurements, only the operation of pushing and pulling the adjusting plate 1115 is required, without the need to frequently use additional devices to pump air and disconnect the capillary viscometer 5, thereby improving the detection efficiency.
