Description

Technical Field

[0001] The present invention relates to the technical field of sealing strip testing, and in particular to a sealing strip tensile performance testing device. Background Art

[0002] As an important component of the vehicle body, automobile sealing strips are widely used in doors, windows, trunks and other parts, playing a key role in sealing, sound insulation, shock absorption and dust prevention. During the driving process of the vehicle, the sealing strips must not only resist wind and rain erosion and isolate external noise, but also buffer the mechanical stress caused by the vibration of the vehicle body to ensure the comfort and safety of the vehicle interior environment. They are in a complex dynamic working environment for a long time, and are affected by multiple factors such as temperature changes, ultraviolet radiation, and mechanical friction. Especially when the doors are frequently opened and closed and the vehicle body is deformed, the sealing strips will be subjected to varying degrees of stretching. The tensile performance directly determines the service life and sealing effect of the sealing strips. Therefore, it is necessary to conduct tensile performance tests on automobile sealing strips and master their key parameters such as tensile strength and elongation. This is an important link to ensure the reliable quality of sealing strips and guarantee the sealing performance and driving experience of the entire vehicle.

[0003] At present, the fixture system design of the tensile performance test device for automobile sealing strips is relatively traditional. The fixture of each sealing strip is independently controlled and lacks a unified control mechanism. When operating, the test personnel must install and disassemble each fixture one by one. Not only are the operation steps cumbersome, time-consuming and labor-intensive, but the overall test efficiency is greatly reduced. Due to the inability to flexibly adjust the fixture control mode, the device is difficult to quickly adapt to the testing needs of sealing strips of different specifications and quantities, resulting in poor flexibility and practicality. It is unable to meet the growing diversified testing needs and has poor flexibility and practicality. Summary of the Invention

The single groups of modules are independently lifted and lowered, so that they can adapt to the detection and use of sealing strips with different length parameters. While the single groups of modules are independently lifted and lowered, they can also realize the function of synchronously controlling the opening and closing state of the connecting mechanism, facilitating the rapid installation and removal of the sealing strip during the detection and testing process, simplifying the operating process, improving work efficiency, and having extremely high flexibility, adaptability and practicality.

[0031] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the described 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.

[0032] Please refer to Figures 1 to 12 :Example 1: The present invention proposes a sealing strip tensile performance testing device, comprising: a seat assembly 1 and a testing assembly, wherein the seat assembly 1 includes a mounting seat 101, and the testing assembly consists of a connecting mechanism 2, a linkage rod 3 and a testing push rod 5; The connecting mechanism 2 is provided with two groups symmetrically in the upper and lower parts inside the mounting seat 101, and the connecting mechanism 2 includes a test seat 201, an adjusting rod 202, a movable clamping block 203, a positioning screw 204, a control block 205, a transmission block 206, a driving block 207 and a linkage cylinder 208. The test seat 201 at the bottom is fixedly mounted on the seat body of the mounting seat 101, and the test seat 201 at the top is fixedly mounted on the bottom of the test push rod 5, the test push rod 5 is fixedly mounted on the top of the mounting seat 101, and the linkage rod 3 is rotatably connected to the inside of the mounting seat 101, and the test seat A fixed clamp 4 is fixedly installed on the outside of 201, the adjusting rod 202 is inserted into the inside of the positioning screw 204, and the positioning screw 204 is rotatably connected to the inside of the test seat 201, the positioning screw 204 is screwed to the inside of the movable clamp 203 through the rod body thread, the control block 205 is rotatably connected to the inside of the positioning screw 204, and the control block 205 is inserted into the inside of the transmission block 206, the transmission block 206 is inserted into the inside of the linkage cylinder 208, and the drive block 207 is inserted into the inside of the linkage cylinder 208, and the linkage cylinder 208 is rotatably connected to the inside of the test seat 201.

[0033] Among them, two groups of symmetrical connecting mechanisms 2, linkage rods 3 and test push rods 5 together constitute a single group module, and the single group module is provided with five groups inside the mounting seat 101, and the number is not limited to five groups, and the number can be increased or decreased. In use, the lower connecting mechanism 2 in each group of single group modules can realize the clamping and fixing of the bottom end of the sealing strip, and the upper connecting mechanism 2 can realize the clamping and fixing of the top end of the sealing strip, so that when the test push rod 5 contracts, it can drive the upper test seat 201 to move up synchronously, thereby performing tensile performance testing on the sealing strip and recording test data. Since the single group modules are set independently of each other, they can automatically adapt to the length of the sealing strip to be tested for testing during testing, and the testing is flexible and convenient.

[0034] Among them, the seat body assembly 1 also includes an upper control motor 102 and a lower control motor 103, the upper control motor 102 and the lower control motor 103 are respectively fixedly connected to the top and bottom of the side of the mounting seat 101, an upper control gear 1021 is provided on the outside of the upper control motor 102 rotating shaft, and a linkage gear 301 is provided on the top of the linkage rod 3, the upper control gear 1021 and the linkage gear 301 are meshed with each other for transmission, a driving gear 2081 is provided on the outside of the cylinder body of the linkage cylinder 208, and a lower control gear 1031 is provided on the outside of the lower control motor 103 rotating shaft, the lower control gear 1031 and the driving gear 2081 located at the lower connecting mechanism 2 are meshed with each other for transmission, a synchronous gear 2011 is provided inside the test seat 201 located at the upper connecting mechanism 2, and the synchronous gear 2011 and The gear meshing transmission of the driving gear 2081 of the upper connecting mechanism 2 allows the connection mechanisms 2 at the bottom of all single-group modules to be synchronously controlled in opening and closing state during use. After all sealing strips are placed inside the connection mechanisms 2 at the corresponding positions, the bottom ends of the sealing strips can be quickly installed and removed. At the same time, the connection mechanisms 2 at the top of the single-group modules can also be synchronously controlled in opening and closing state, so that the sealing strips can be quickly removed after the test is completed. It is convenient and flexible to use, and the opening and closing states of all the lower connection mechanisms 2 can be synchronously controlled by the lower control motor 103. When the lower control motor 103 rotates, the lower control gear 1031 outside the rotating shaft of the lower control motor 103 can be 2, the driving gear 2081 drives the linkage cylinder 208 to rotate, and the linkage cylinder 208 can drive the driving block 207 to rotate synchronously when rotating. Under the action of the clutch top spring 2071, when the driving block 207 rotates, the transmission convex ball 2072 can drive the transmission block 206 to rotate synchronously through the transmission groove 2061, and the transmission block 206 can drive the control block 205 to rotate synchronously when rotating. When the control block 205 rotates, the integral tooth block 2052 can drive the positioning screw 204 to rotate through the integral tooth groove 2041. When the positioning screw 204 rotates, it can drive the positioning screw 204 to rotate through the rod thread. When the positioning screw 204 rotates, it can drive the movable clamping block 203 to move, thereby regulating the position between the fixed clamping block 4 and the movable clamping block 203. When the upper control motor 102 rotates, the upper control gear 1021 can drive the linkage rod 3 to rotate through the linkage gear 301, and the linkage rod 3 can drive the synchronous gear 2011 to rotate when rotating. When the synchronous gear 2011 rotates, it can drive the linkage cylinder 208 of the upper connection mechanism 2 to rotate through the upper driving gear 2081, thereby realizing unified opening and closing control of the upper connection mechanism 2, and adopting the method of driving the synchronous gear 2011 by the linkage rod 3, so that no matter the upper connection mechanism 2 is in any use position,The linkage rod 3 can always drive the synchronous gear 2011 to rotate to realize the opening and closing control, and the use is stable.

[0035] Among them, the side of the block body of the driving block 207 is provided with a clutch top spring 2071, and the two ends of the clutch top spring 2071 are respectively against the side of the driving block 207 and the inside of the linkage cylinder 208, the side of the driving block 207 is provided with a transmission convex ball 2072, and the side of the transmission block 206 is provided with a transmission groove 2061, and the transmission convex ball 2072 is inserted into the inside of the transmission groove 2061. In use, the connecting mechanism 2 has the function of limiting the maximum opening and closing degree, so that when sufficient pressure is applied to the sealing strip or the maximum opening and closing degree is reached, the group of connecting mechanisms 2 can automatically trigger the limit function to avoid damage, and at the same time will not affect the other connecting mechanisms. The opening and closing control of the connecting mechanism 2 can adapt to the installation and disassembly testing of sealing strips with different parameters such as thickness. When the connecting mechanism 2 reaches the maximum opening and closing degree or reaches the maximum clamping force, the movement resistance of the movable clamping block 203 increases infinitely, so that the transmission force obtained by the transmission convex ball 2072 and the transmission groove 2061 through the clutch top spring 2071 will fail. That is, slippage will occur between the transmission convex ball 2072 and the transmission groove 2061, causing the driving block 207 to move in the direction away from the transmission block 206 and compress the clutch top spring 2071, thereby preventing the connecting mechanism 2 from continuing to open and close and causing damage to the device. The stability and adaptability are extremely strong.

[0036] Among them, the control block 205 is provided with a reset spring 2051, and the two ends of the reset spring 2051 are respectively against the inside of the control block 205 and the inside of the transmission block 206, the control block 205 is provided with an integral tooth block 2052 on the outside, and the positioning screw 204 is provided with an integral tooth groove 2041 on the inside. Under the action of the reset spring 2051, when the adjusting rod 202 is not pressed by external force, the integral tooth block 2052 is plugged into the inside of the integral tooth groove 2041. In use, each group of connecting mechanisms 2 also has the function of separate control, so that it is convenient to install the sealing strip on any group of single modules during testing. During the disassembly operation, when the adjusting rod 202 of the connecting mechanism 2 to be adjusted is pressed, the adjusting rod 202 can drive the control block 205 to move synchronously and compress the reset top spring 2051, and at the same time, the integral tooth block 2052 is also disengaged from the interior of the integral tooth groove 2041. Therefore, when the adjusting rod 202 is rotated thereafter, the adjusting rod 202 can only drive the positioning screw 204 to rotate alone through the rod body with a regular polygonal cross-section, and will not continue to transmit the control block 205 and its subsequent components, thereby avoiding affecting the use status of the remaining connecting mechanisms 2. It can be adjusted and used according to actual test requirements, further improving the adaptability of the device.

[0037] Among them, the rod cross-section of the linkage rod 3, the block cross-section of the driving block 207 and the rod cross-section of the adjusting rod 202 are all designed as regular polygons, and the rod body part of the linkage rod 3 with a regular polygon cross-section is inserted into the interior of the synchronous gear 2011. This design enables the linkage rod 3 to drive the synchronous gear 2011 to rotate, and the driving block 207 can only move axially inside the linkage cylinder 208. The rotation states of the driving block 207 and the linkage cylinder 208 are always the same. The adjusting rod 202 can drive the positioning screw 204 to rotate synchronously, thereby improving the stability of the device.

[0038] Specific usage and function of this embodiment: In the present invention, the lower connecting mechanism 2 in each group of single-group modules can realize the clamping and fixing of the bottom end of the sealing strip, and the upper connecting mechanism 2 can realize the clamping and fixing of the top end of the sealing strip, so that when the test push rod 5 contracts, it can drive the upper test seat 201 to move upward synchronously, thereby performing a tensile performance test on the sealing strip and recording the test data. Since the single-group modules are independently arranged, they can automatically adapt to the length of the sealing strip to be tested for testing during the test. The lower connecting mechanisms 2 in all single-group modules can realize synchronous control of the opening and closing states, and can realize the rapid installation and removal operation of the bottom end of the sealing strip after all the sealing strips are placed inside the lower connecting mechanism 2 at the corresponding position. At the same time, the single-group The upper connecting mechanisms 2 in the module can also realize synchronous control of the opening and closing state operation, so that after the test is completed, the sealing strip can be quickly disassembled, which is convenient and flexible to use. The opening and closing states of all the lower connecting mechanisms 2 can be synchronously controlled by the lower control motor 103. When the lower control motor 103 rotates, the lower control gear 1031 outside the rotating shaft of the lower control motor 103 can drive the linkage cylinder 208 to rotate through the driving gear 2081 of the lower connecting mechanism 2. When the linkage cylinder 208 rotates, it can drive the driving block 207 to rotate synchronously. Under the action of the clutch top spring 2071, when the driving block 207 rotates, the transmission convex ball 2072 can drive the transmission block 206 to rotate synchronously through the transmission groove 2061. The transmission block 206 When rotating, it can drive the control block 205 to rotate synchronously. When the control block 205 rotates, the integral tooth block 2052 can drive the positioning screw 204 to rotate through the integral tooth groove 2041. When the positioning screw 204 rotates, it can drive the positioning screw 204 to rotate through the rod thread. When the positioning screw 204 rotates, it can drive the movable clamping block 203 to move, thereby regulating the use distance between the fixed clamping block 4 and the movable clamping block 203, that is, the opening and closing state. At the same time, it also realizes the unified opening and closing control of the lower connecting mechanism 2, which is easy to operate and flexible to use. The upper control motor 102 can realize synchronous control of the opening and closing states of all upper connecting mechanisms 2. When the upper control motor 102 rotates, the upper control gear 1021 can drive the linkage gear 301 through the linkage gear 301 When the rod 3 rotates, the linkage rod 3 can drive the synchronous gear 2011 to rotate. When the synchronous gear 2011 rotates, it can drive the linkage cylinder 208 of the upper connecting mechanism 2 to rotate through the upper driving gear 2081, thereby realizing unified opening and closing control of the upper connecting mechanism 2. The linkage rod 3 drives the synchronous gear 2011, so that no matter where the upper connecting mechanism 2 is in any use position, the linkage rod 3 can always drive the synchronous gear 2011 to rotate to realize opening and closing control. The connecting mechanism 2 has the function of limiting the maximum opening and closing degree. When sufficient pressure is applied to the sealing strip or the maximum opening and closing degree is reached, the group of connecting mechanisms 2 can automatically trigger the limit function to avoid damage, and at the same time will not affect the opening and closing control of other connecting mechanisms 2.It can adapt to the installation and disassembly test of sealing strips with different parameters such as thickness. When the connecting mechanism 2 reaches the maximum opening and closing degree or reaches the maximum clamping force, the movement resistance of the movable clamping block 203 increases infinitely, so that the transmission force obtained by the transmission convex ball 2072 and the transmission groove 2061 through the clutch top spring 2071 will fail. That is, there will be a slippage between the transmission convex ball 2072 and the transmission groove 2061, causing the driving block 207 to move in the direction away from the transmission block 206 and compress the clutch top spring 2071, preventing the connecting mechanism 2 from continuing to open and close and causing damage to the device. Each group of connecting mechanisms 2 also has the function of separate control, so This facilitates installation and removal of the sealing strips on any single module group during testing. When the adjustment rod 202 of the connection mechanism 2 to be adjusted is pressed, the adjustment rod 202 can drive the control block 205 to move synchronously and compress the reset spring 2051. At the same time, it also causes the integral tooth block 2052 to disengage from the integral tooth groove 2041. Therefore, when the adjustment rod 202 is rotated thereafter, the adjustment rod 202 can only drive the positioning screw 204 to rotate independently through the rod body with a regular polygonal cross-section, and will not continue to drive the control block 205 and its subsequent components, avoiding affecting the use status of the remaining connection mechanisms 2. Adjustment and use can be performed according to actual testing needs.
