Description

Technical Field

[0001] The invention relates to the field of silicone rubber detection, and in particular to a silicone rubber detection device and method. Background Art

[0002] Silicone rubber is an elastomeric material based on siloxane polymers. Due to its excellent physical and chemical properties, silicone rubber has excellent high temperature resistance, low temperature resistance, chemical corrosion resistance, electrical insulation performance, and excellent biocompatibility. Therefore, it has a wide range of applications in industry, electronics, medical treatment, aerospace and other fields.

[0003] Silicone rubber testing equipment is a general term for various professional equipment used to evaluate the performance of silicone rubber. These devices play a vital role in the quality control, performance evaluation and new product development of silicone rubber. Common silicone rubber testing equipment includes silicone rubber material testing machines, aging test chambers and oil-resistant test chambers. Among them, the silicone rubber material testing machine is mainly used to test the tensile, compression, bending and other mechanical properties of silicone rubber. It is one of the most commonly used equipment in the physical and mechanical properties testing of silicone rubber.

[0004] However, when using a silicone rubber material testing machine to test the mechanical properties of silicone rubber, such as tension, compression and bending, it is necessary to fix the silicone rubber at the corresponding testing position one by one, which is cumbersome to operate. In addition, the existing silicone rubber material testing machine mainly drives the stretching table for tensile testing to move up and down through two lifting structures, namely a threaded lifting structure and a gear lifting structure. In order to ensure the normal use of the silicone rubber material testing machine using a threaded lifting structure, it is necessary to manually add lubricating oil to the lifting threaded rod regularly. Since this equipment is lubricated by manually adding lubricating oil, during the long-term use of this equipment, the staff may forget to add lubricating oil, which will increase the friction coefficient of the threaded rod and accelerate its wear. Lack of lubrication may cause the threaded rod to get stuck or break, increasing the risk of failure. Therefore, it does not meet the existing needs. We have proposed a silicone rubber testing device and method. Summary of the invention

[0018] Based on the above silicone rubber detection device, an embodiment of the present invention further provides a silicone rubber detection method, which includes the following steps:

[0019] Step A: Pick up the silicone rubber to be tested, and fix its top end inside the silicone rubber stretching clamping head, then drive two self-lubricating threaded rods to rotate through the silicone rubber material testing machine to move the stretching lifting platform connected to it through the threaded structure upward, until the bottom end of the silicone rubber moves between the two silicone rubber bottom end fixing heads located inside the stretching lifting platform, then push the two silicone rubber bottom end fixing heads inward synchronously through the fixed single-bar cylinder to fix the bottom end of the silicone rubber, when the top end and the bottom end of the silicone rubber are fixed, start the sliding table to move along the arc-shaped slide rail, when the sliding table moves, the silicone rubber stretching clamping head fixed thereto will move along the arc-shaped slide rail together, when the silicone rubber stretching clamping head fixing the top end of the silicone rubber moves along the arc-shaped slide rail, the silicone rubber can be bent;

[0020] Step B: After the bending mechanical property test of the silicone rubber is completed, the silicone rubber stretching clamping head is adjusted back to the original angle through the sliding table, and then the silicone rubber material testing machine is started to drive the self-lubricating threaded rod to rotate, so as to move the stretching lifting table downward. When the stretching lifting table moves downward, the silicone rubber will be stretched;

[0021] Step C: If the silicone rubber is broken due to the tensile mechanical properties test, directly start the fixing single-bar cylinder to pull the fixing head at the bottom end of the silicone rubber outwards; if the silicone rubber is not broken due to the mechanical properties test, first move the stretching lifting platform upwards; after moving the stretching lifting platform back to its original position, first release the fixation between the silicone rubber stretching clamping head and the top end of the silicone rubber, and then pull the fixing head at the bottom end of the silicone rubber outwards to release the fixation of the bottom end of the silicone rubber; when the fixation of the top end and the bottom end of the silicone rubber are both released, the silicone rubber will fall to the upper end surfaces of the two silicone rubber support platforms under the action of gravity, and the inclined surface on the upper end surface of the silicone rubber compression detection pressing plate can prevent the silicone rubber from being stuck on the upper end surface of the silicone rubber compression detection pressing plate;

[0022] Step D: After the silicone rubber falls to the upper end surfaces of the two silicone rubber support platforms, the synchronous transmission stepper motor is started. The synchronous transmission stepper motor can drive the transmission shaft connected to it to rotate. The rotating transmission shaft can drive the synchronous sprocket fixedly mounted on the outer surface of the transmission shaft and the large synchronous sprocket connected in series with it through the synchronous chain to rotate together. When the large synchronous sprocket rotates, the external thread ring penetrated by the two transmission rods fixed on the upper end surface of the large synchronous sprocket will rotate together. Through the internal thread transmission of the internal thread annular groove, when the external thread ring rotates When the external thread ring is moved up and down, the external thread ring is moved upward. As the external thread ring rises, the inclined pushing surface on the upper end face of the external thread ring will contact the metal rod and push the metal rod inward. When the metal rod moves inward, the metal ring fixedly sleeved on the outer surface of the metal rod will move inward together and squeeze the spring. At the same time, the silicone rubber compression detection pressing plate fixed to the metal rod will move inward synchronously. The inwardly moving silicone rubber compression detection pressing plate will contact the silicone rubber and perform compression mechanical property test on it.

[0023] Step E: After the compression mechanical property test of the silicone rubber is completed, the synchronous transmission stepper motor is started again, and the transmission shaft is rotated in the opposite direction this time to move the external thread ring downward. As the external thread ring descends and the reaction force of the squeezed spring, the silicone rubber compression detection pressure plate will be gradually pushed back to its original position to release the compression of the silicone rubber. When the inclined pushing surface on the upper end face of the external thread ring moves to the position of the silicone rubber support platform and the external thread ring continues to move downward, the spring force of the reset spring can push the connector and the silicone rubber support platform fixed thereto outward. As the two silicone rubber support platforms move, a gap will be generated between the two silicone rubber support platforms, and the silicone rubber that falls to the upper end face of the silicone rubber support platform will pass through the gap and fall into the interior of the silicone rubber storage tray.

[0024] Step F: After the self-lubricating threaded rod located outside has been used for a week, the lifting horizontal bar cylinder will automatically pull the inverted U-shaped tube upwards at twelve o'clock that night. As the inverted U-shaped tube rises, a gap will be generated between the lower end surface of the inverted U-shaped tube and the cylindrical groove, and the lubricating oil inside the inverted U-shaped tube can enter the interior of the cylindrical groove through the gap, and flow to the outer surface of the lifting threaded rod through the through hole connected to the interior of the cylindrical groove. After the inverted U-shaped tube is pulled upward for five seconds, the lifting horizontal bar cylinder will push the inverted U-shaped tube back to its original position, and then slowly drive the self-lubricating threaded rod to rotate through the silicone rubber material testing machine, and move to drive the stretching lifting platform connected to it through the threaded structure to move up and down on the outer surface of the self-lubricating threaded rod, and when lubricating oil needs to be added, remove the threaded sealing cover on the outer surface of the oil filling port, and then directly pour the lubricating oil into the interior of the oil filling port.

[0025] The present invention can automatically perform mechanical tests on the silicone rubber in terms of bending, stretching and compression one by one through a multi-faceted mechanical testing mechanism for silicone rubber, thereby reducing the cumbersomeness of the operation of the equipment when performing mechanical testing on the silicone rubber, and the above technical scheme improves the convenience of operation of the equipment; the self-lubricating threaded rod can cause the through hole located on the outer surface of the lifting threaded rod to flow out lubricating oil regularly, and when the lubricating oil flows out of the through hole, the lifting threaded rod is driven to rotate slowly by a silicone rubber material testing machine, thereby driving the stretching lifting platform connected to it by a threaded structure to move up and down, and the lubricating oil that flows out can be applied to the outer surface of the lifting threaded rod by the stretching lifting platform that moves up and down, and the above technology can regularly lubricate the lifting threaded rod, thereby preventing the staff from forgetting to add lubricating oil, which leads to an increase in the friction coefficient of the lifting threaded rod, accelerating its wear, and preventing it from getting stuck or breaking due to lack of lubrication.

[0034] Specifically, a multi-faceted detection mechanism for silicone rubber mechanics is provided above the silicone rubber material testing machine 1, and the multi-faceted detection mechanism for silicone rubber mechanics includes an arc top 3, an arc slide rail 4, a sliding table 5, a silicone rubber stretching clamping head 6, a stretching lifting table 7, an arc head 8, a through port 9, two silicone rubber bottom end fixing heads 10, two fixed single-bar cylinders 11, two silicone rubber compression detection pressing plates 25, two silicone rubber supporting tables 20 and a step-by-step pushing mechanism, the arc slide rail 4 is located in the middle position of the lower end surface of the arc top 3, the sliding table 5 is installed inside the arc slide rail 4, and the silicone rubber stretching clamping head 6 is installed on the lower end surface of the sliding table 5;

[0035] The stretching lifting platform 7 is located below the silicone rubber stretching clamping head 6, the arc head 8 is located in the middle of the upper end surface of the stretching lifting platform 7, the through port 9 is located in the middle of the upper end surface of the arc head 8 and passes through the stretching lifting platform 7, and the two silicone rubber bottom end fixing heads 10 are respectively located at the two ends of the upper side of the through port 9, and the piston rods of the two fixing single-bar cylinders 11 are respectively connected to the two silicone rubber bottom end fixing heads 10, and the positions of the two silicone rubber bottom end fixing heads 10 correspond to the positions of the silicone rubber stretching clamping head 6;

[0036] The two silicone rubber compression detection pressure plates 25 are respectively located below the two silicone rubber bottom end fixing heads 10, and the two silicone rubber support platforms 20 are respectively located below the two silicone rubber compression detection pressure plates 25. The gradual pushing mechanism can gradually push the two silicone rubber support platforms 20 and the two silicone rubber compression detection pressure plates 25 inward, and the opposite surfaces of the two silicone rubber support platforms 20 are in contact with each other.

[0037] When the equipment is needed, pick up the silicone rubber to be tested and fix its top end inside the silicone rubber stretching clamping head 6, then drive the two self-lubricating threaded rods 2 to rotate through the silicone rubber material testing machine 1 to move upward the stretching lifting platform 7 connected to it through the threaded structure until the bottom end of the silicone rubber moves between the two silicone rubber bottom end fixing heads 10 located inside the stretching lifting platform 7, then push the two silicone rubber bottom end fixing heads 10 inward synchronously through the fixing single-bar cylinder 11 to fix the bottom end of the silicone rubber. After the top and bottom ends are fixed, start the sliding table 5 to move along the arc-shaped slide rail 4. When the sliding table 5 moves, the silicone rubber stretching clamping head 6 fixed thereto will move along the arc-shaped slide rail 4. When the silicone rubber stretching clamping head 6 fixing the top end of the silicone rubber moves along the arc-shaped slide rail 4, the silicone rubber can be bent. By bending the silicone rubber, the bending mechanical properties of the silicone rubber can be tested. In addition, the arc-shaped head 8 located on the upper end surface of the stretching lifting table 7 can prevent the moving silicone rubber stretching clamping head 6 from directly colliding with the stretching lifting table 7.

[0038] After the bending mechanical property test of the silicone rubber is completed, the silicone rubber stretching clamping head 6 is adjusted back to the original angle through the sliding table 5, and then the silicone rubber material testing machine 1 is started to drive the self-lubricating threaded rod 2 to rotate, so as to move the stretching lifting table 7 downward. When the stretching lifting table 7 moves downward, the silicone rubber will be stretched, and the tensile mechanical properties of the silicone rubber can be tested by stretching it.

[0039] Furthermore, the step-by-step pushing mechanism includes a synchronous transmission stepper motor 12, the output shaft of the synchronous transmission stepper motor 12 is connected to a transmission shaft 13 through a coupling, a synchronous sprocket 14 is fixedly sleeved on the outer surface of the transmission shaft 13, a large synchronous sprocket 15 is provided on one side of the synchronous sprocket 14, and the synchronous sprocket 14 and the large synchronous sprocket 15 are connected in series through a synchronous chain 16; an internal threaded annular groove 17 is provided above the large synchronous sprocket 15, an external threaded ring 18 matching its internal thread is provided inside the internal threaded annular groove 17, and a transmission rod 19 vertically movable through the external threaded ring 18 is fixedly provided on both sides of the upper end surface of the large synchronous sprocket 15; a connector 24 is provided on both sides of the inner part of the external threaded ring 18, and the upper end surfaces of the two connectors 24 are respectively connected to the two silicone rubber support tables 20 The two connecting heads 24 are fixed with a guide rod 22 on their opposite surfaces, and a reset spring 23 is sleeved on the outer surface of the guide rod 22; the upper end surface of the external threaded ring 18 is an inclined pushing surface 21, and a metal rod 26 is provided on both sides above the inclined pushing surface 21, and the two metal rods 26 are respectively fixed with two silicone rubber compression detection pressing plates 25, and the upper end surface of the silicone rubber compression detection pressing plate 25 is an inclined surface 30; a metal ring 27 is sleeved on one side of the outer surface of the metal rod 26, and a spring 28 is provided on one side of the metal ring 27 which is also sleeved on the outer surface of the metal rod 26, and the two ends of the spring 28 are respectively connected between the metal ring 27 and the inside of the stretching lifting platform 7; a silicone rubber receiving tray 29 is provided below the through-port 9, and the position of the silicone rubber receiving tray 29 corresponds to the position of the through-port 9.

[0040] If the silicone rubber breaks due to the tensile mechanical properties test, the fixing single-bar cylinder 11 is directly started to pull the silicone rubber bottom end fixing head 10 outward. If the silicone rubber does not break due to the mechanical properties test, the stretching lifting platform 7 is first moved upward. After the stretching lifting platform 7 is moved back to its original position, the fixation between the silicone rubber stretching clamping head 6 and the top end of the silicone rubber is first released, and then the silicone rubber bottom end fixing head 10 is pulled outward to release the fixation of the silicone rubber bottom end. This is to prevent the silicone rubber from flying directly out of the equipment due to its inertia when the silicone rubber in the stretched state is directly released. When the fixation of the top and bottom ends of the silicone rubber is released, the silicone rubber will fall to the upper end surfaces of the two silicone rubber support platforms 20 under the action of gravity, and the inclined surface 30 located on the upper end surface of the silicone rubber compression detection pressing plate 25 can prevent the silicone rubber from being stuck on the upper end surface of the silicone rubber compression detection pressing plate 25.

[0041] When the silicone rubber falls to the upper end surfaces of the two silicone rubber support platforms 20, the synchronous transmission stepper motor 12 is started, and the synchronous transmission stepper motor 12 can drive the transmission shaft 13 connected thereto to rotate. The rotating transmission shaft 13 can drive the synchronous sprocket 14 fixedly sleeved on the outer surface of the transmission shaft 13 and the large synchronous sprocket 15 connected thereto in series through the synchronous chain 16 to rotate together. When the large synchronous sprocket 15 rotates, the external thread ring 18 penetrated by the two transmission rods 19 fixed on the upper end surface of the large synchronous sprocket 15 will rotate together, and the internal thread transmission of the internal thread annular groove 17 will cause the external thread ring 18 to rotate. , the external thread ring 18 will move up and down accordingly. At this time, the external thread ring 18 is moved upward. As the external thread ring 18 rises, the inclined pushing surface 21 located on the upper end surface of the external thread ring 18 will contact the metal rod 26 and push the metal rod 26 inward. When the metal rod 26 moves inward, the metal ring 27 fixedly mounted on the outer surface of the metal rod 26 will move inward together and squeeze the spring 28. At the same time, the silicone rubber compression detection pressing plate 25 also fixed to the metal rod 26 will move inward synchronously therewith. The inwardly moving silicone rubber compression detection pressing plate 25 will contact the silicone rubber and perform compression mechanical property detection on it.

[0042] When the compression mechanical property test of the silicone rubber is completed, the synchronous transmission stepper motor 12 is started again, and the transmission shaft 13 is rotated in the opposite direction this time to move the external threaded ring 18 downward. As the external threaded ring 18 descends and the reaction force of the squeezed spring 28 is applied, the silicone rubber compression detection pressing plate 25 will be gradually pushed back to its original position to release the compression of the silicone rubber. When the inclined pushing surface 21 on the upper end face of the external threaded ring 18 moves to the position of the silicone rubber support platform 20 and the external threaded ring 18 continues to move downward, the reset spring 23 is used to release the silicone rubber compression detection pressing plate 25. The spring force can push the connecting head 24 and the silicone rubber support platform 20 fixed thereto outward. As the two silicone rubber support platforms 20 move, a gap will be generated between the two silicone rubber support platforms 20, and the silicone rubber that falls to the upper end surface of the silicone rubber support platform 20 will fall into the silicone rubber storage tray 29 through this gap. The above technical solution can automatically perform mechanical tests on the silicone rubber in terms of bending, stretching and compression one by one, thereby reducing the cumbersomeness of the operation of the equipment when performing mechanical testing on the silicone rubber and improving the convenience of the equipment.

[0043] When the device needs to be used again, the external thread ring 18 is moved upward by the synchronous transmission stepper motor 12. As the external thread ring 18 rises, the inclined pushing surface 21 located on its upper end surface will contact the two silicone rubber support platforms 20 and push them inward. When the two silicone rubber support platforms 20 are closed to each other, the silicone rubber support platforms 20 will also cross the inclined pushing surface 21 and contact the inner wall of the external thread ring 18. Then, the transmission stepper motor 12 is turned off to keep the two silicone rubber support platforms 20 closed to each other. At the same time, the silicone rubber compression detection pressure plate 25 has not been pushed inward.

[0044] Furthermore, the self-lubricating threaded rod 2 also includes an oil filling port 205, which is communicated with the interior of the inverted U-shaped tube 203, and a threaded sealing cover 206 is installed on the upper side of the outer surface of the oil filling port 205 through a threaded structure; after the self-lubricating threaded rod 2 located in the outside has been used for a week, the lifting horizontal bar cylinder 207 will automatically pull the inverted U-shaped tube 203 upward at twelve o'clock that night, and the timing operation of the horizontal bar cylinder 207 can be controlled by a control device matched with the silicone rubber material testing machine 1. As the inverted U-shaped tube 203 rises, a gap will be generated between the lower end surface of the inverted U-shaped tube 203 and the cylindrical groove 202, and the lubricating oil 204 located in the inverted U-shaped tube 203 can enter the interior of the cylindrical groove 202 through this gap, and flow to the outer surface of the lifting threaded rod 201 through the through hole 208 communicated with the interior of the cylindrical groove 202. When the inverted U-shaped tube 203 is pulled upward for five seconds, a gap will be generated between the lower end surface of the inverted U-shaped tube 203 and the cylindrical groove 202. After that, the lifting horizontal bar cylinder 207 will push the inverted U-shaped tube 203 back to its original position, and then the self-lubricating threaded rod 2 will be slowly driven to rotate by the silicone rubber material testing machine 1, and the movement will drive the stretching lifting platform 7 connected to it by the threaded structure to move up and down on the outer surface of the self-lubricating threaded rod 2, and the outflowing lubricating oil 204 can be applied to the outer surface of the lifting threaded rod 201 by the stretching lifting platform 7 that moves up and down. Through the above-mentioned technology, the lifting threaded rod 201 can be lubricated regularly to prevent the staff from forgetting to add lubricating oil 204, thereby increasing the friction coefficient of the lifting threaded rod 201 and accelerating its wear, and preventing it from getting stuck or breaking due to lack of lubrication. When it is necessary to add lubricating oil 204, the threaded sealing cover 206 located on the outer surface of the oil filling port 205 is removed, and then the lubricating oil 204 is directly poured into the interior of the oil filling port 205.

[0045] Based on the above silicone rubber detection device, the present invention also provides a silicone rubber detection method, which comprises the following steps:

[0046] Step A: Pick up the silicone rubber to be tested, and fix its top end inside the silicone rubber stretching clamping head, then drive two self-lubricating threaded rods to rotate through the silicone rubber material testing machine to move the stretching lifting platform connected to it through the threaded structure upward, until the bottom end of the silicone rubber moves between the two silicone rubber bottom end fixing heads located inside the stretching lifting platform, then push the two silicone rubber bottom end fixing heads inward synchronously through the fixed single-bar cylinder to fix the bottom end of the silicone rubber, when the top end and the bottom end of the silicone rubber are fixed, start the sliding table to move along the arc-shaped slide rail, when the sliding table moves, the silicone rubber stretching clamping head fixed thereto will move along the arc-shaped slide rail together, when the silicone rubber stretching clamping head fixing the top end of the silicone rubber moves along the arc-shaped slide rail, the silicone rubber can be bent;

[0047] Step B: After the bending mechanical property test of the silicone rubber is completed, the silicone rubber stretching clamping head is adjusted back to the original angle through the sliding table, and then the silicone rubber material testing machine is started to drive the self-lubricating threaded rod to rotate, so as to move the stretching lifting table downward. When the stretching lifting table moves downward, the silicone rubber will be stretched;

[0048] Step C: If the silicone rubber is broken due to the tensile mechanical properties test, directly start the fixing single-bar cylinder to pull the fixing head at the bottom end of the silicone rubber outwards; if the silicone rubber is not broken due to the mechanical properties test, first move the stretching lifting platform upwards; after moving the stretching lifting platform back to its original position, first release the fixation between the silicone rubber stretching clamping head and the top end of the silicone rubber, and then pull the fixing head at the bottom end of the silicone rubber outwards to release the fixation of the bottom end of the silicone rubber; when the fixation of the top end and the bottom end of the silicone rubber are both released, the silicone rubber will fall to the upper end surfaces of the two silicone rubber support platforms under the action of gravity, and the inclined surface on the upper end surface of the silicone rubber compression detection pressing plate can prevent the silicone rubber from being stuck on the upper end surface of the silicone rubber compression detection pressing plate;

[0049] Step D: After the silicone rubber falls to the upper end surfaces of the two silicone rubber support platforms, the synchronous transmission stepper motor is started. The synchronous transmission stepper motor can drive the transmission shaft connected to it to rotate. The rotating transmission shaft can drive the synchronous sprocket fixedly mounted on the outer surface of the transmission shaft and the large synchronous sprocket connected in series with it through the synchronous chain to rotate together. When the large synchronous sprocket rotates, the external thread ring penetrated by the two transmission rods fixed on the upper end surface of the large synchronous sprocket will rotate together. Through the internal thread transmission of the internal thread annular groove, when the external thread ring rotates When the external thread ring is moved up and down, the external thread ring is moved upward. As the external thread ring rises, the inclined pushing surface on the upper end face of the external thread ring will contact the metal rod and push the metal rod inward. When the metal rod moves inward, the metal ring fixedly sleeved on the outer surface of the metal rod will move inward together and squeeze the spring. At the same time, the silicone rubber compression detection pressing plate fixed to the metal rod will move inward synchronously. The inwardly moving silicone rubber compression detection pressing plate will contact the silicone rubber and perform compression mechanical property test on it.

[0050] Step E: After the compression mechanical property test of the silicone rubber is completed, the synchronous transmission stepper motor is started again, and the transmission shaft is rotated in the opposite direction this time to move the external thread ring downward. As the external thread ring descends and the reaction force of the squeezed spring, the silicone rubber compression detection pressure plate will be gradually pushed back to its original position to release the compression of the silicone rubber. When the inclined pushing surface on the upper end face of the external thread ring moves to the position of the silicone rubber support platform and the external thread ring continues to move downward, the spring force of the reset spring can push the connector and the silicone rubber support platform fixed thereto outward. As the two silicone rubber support platforms move, a gap will be generated between the two silicone rubber support platforms, and the silicone rubber that falls to the upper end face of the silicone rubber support platform will pass through the gap and fall into the interior of the silicone rubber storage tray.

[0051] Step F: After the self-lubricating threaded rod located outside has been used for a week, the lifting horizontal bar cylinder will automatically pull the inverted U-shaped tube upwards at twelve o'clock that night. As the inverted U-shaped tube rises, a gap will be generated between the lower end surface of the inverted U-shaped tube and the cylindrical groove, and the lubricating oil inside the inverted U-shaped tube can enter the interior of the cylindrical groove through the gap, and flow to the outer surface of the lifting threaded rod through the through hole connected to the interior of the cylindrical groove. After the inverted U-shaped tube is pulled upward for five seconds, the lifting horizontal bar cylinder will push the inverted U-shaped tube back to its original position, and then slowly drive the self-lubricating threaded rod to rotate through the silicone rubber material testing machine, and move to drive the stretching lifting platform connected to it through the threaded structure to move up and down on the outer surface of the self-lubricating threaded rod, and when lubricating oil needs to be added, remove the threaded sealing cover on the outer surface of the oil filling port, and then directly pour the lubricating oil into the interior of the oil filling port.

[0052] In summary, the silicone rubber detection device and method provided by the present invention can automatically perform mechanical tests on silicone rubber in terms of bending, stretching, and compression one by one through a multi-faceted mechanical detection mechanism for silicone rubber, thereby reducing the cumbersomeness of the operation of the equipment when performing mechanical testing on silicone rubber. The above technical solution improves the convenience of operation of the equipment.

[0053] The silicone rubber detection device and method provided by the present invention can also use a self-lubricating threaded rod to allow the through hole located on the outer surface of the lifting threaded rod to regularly flow out lubricating oil. After the lubricating oil flows out of the through hole, the lifting threaded rod is driven to rotate slowly by the silicone rubber material testing machine, thereby driving the stretching lifting platform connected to it by the threaded structure to move up and down. The outflowing lubricating oil can be applied to the outer surface of the lifting threaded rod by the stretching lifting platform that moves up and down. Through the above technology, the lifting threaded rod can be lubricated regularly, thereby preventing the staff from forgetting to add lubricating oil, which leads to an increase in the friction coefficient of the lifting threaded rod, accelerating its wear, and preventing it from getting stuck or breaking due to lack of lubrication.

[0054] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
