Technical Field
[0001] The utility model relates to a colloid adhesion test, in particular to a connecting tool for the colloid adhesion test. Background Art
[0002] In the manufacture of honeycomb panels, usually after the processing of the honeycomb panels is completed, thin plates are bonded on the front and back of the honeycomb panels to ensure the strength of the honeycomb panels and prevent the honeycomb panels from deformation. When bonding the thin plates, colloids are usually required, and the bonding strength of the colloids affects the performance of the honeycomb panels to a certain extent.
[0003] In order to test the adhesion degree of the colloid, the thin plate and the honeycomb plate of the honeycomb panel are usually fixed, and then the adhesion degree of the colloid is tested by pulling with the help of an external tensile testing machine. However, in traditional situations, when fixing the thin plate and the honeycomb plate, a direct connection and fixation method is usually adopted, that is, the output end of the external tensile testing machine is directly connected to the thin plate, and the honeycomb plate of the honeycomb panel is directly connected to the fixed end of the tensile testing machine. However, in this way, the direction of the force is easily offset as the pulling proceeds, thereby affecting the tensile test results, that is, affecting the adhesion test results. Therefore, it is urgent to design a connection tool for colloid adhesion testing to solve the above problems. Utility Model Content

[0005] The technical solution adopted by the utility model to solve the technical problem is: a connecting tool for testing the adhesion of colloids, comprising: a roller body, a connecting strip, a tensile machine fixing part and an elliptical shaft body;
[0006] The roller body is a circular cylindrical structure, with discs provided on both sides of the roller body, and an annular groove is provided along the arc surface of the disc;
[0007] The arc surface of the roller body is provided with an arc groove along the axial direction;
[0008] Connecting shafts are connected to both sides of the elliptical shaft body. Through holes corresponding to the connecting shafts are opened at the positions of the two discs corresponding to the arc grooves. The connecting shafts pass through the through holes and are rotatably connected to the through holes. The elliptical shaft body is located in the arc groove, and by rotating the elliptical shaft body, the elliptical shaft body can fit with the wall of the arc groove;
[0009] There are two connecting bars, one end of each of which is fixed to the annular grooves of the two discs via corresponding fixing bolts.
[0010] The other ends of the two connecting strips are connected to the fixing part of the tensile machine.
[0011] As a preferred technical solution of the present invention, the center of the disc coincides with the center of the roller body.
[0012] By adopting the above technical solution, since the center of the disc coincides with the center of the roller, it can be ensured that when the disc rotates along the axis, the roller can synchronously rotate along the axis with the same amplitude.
[0013] As a preferred technical solution of the present invention, the center of the annular groove coincides with the center of the disc.
[0014] By adopting the above technical solution, since the center of the annular groove coincides with the center of the disc, it can be ensured that when the disc rotates along the axis, the annular groove can synchronously rotate along the axis with the same amplitude.
[0015] As a preferred technical solution of the present invention, a wrench portion is provided at one end of the connecting shaft away from the roller body.
[0016] By adopting the above technical solution and providing the wrench portion, the connecting shaft can be conveniently rotated by means of an external wrench in cooperation with the wrench portion.
[0017] As a preferred technical solution of the present invention, the position of the fixing bolt corresponds to the arc groove, and the length of the connecting strip corresponds to the circumference of the annular groove.
[0018] By adopting the above technical solution, since the position of the fixing bolt corresponds to the arc groove and the length of the connecting strip corresponds to the circumference of the annular groove, the stretching space of the tensile testing machine can be fully utilized while ensuring the stretching distance during testing.
[0019] The beneficial effects of the present invention are as follows:
[0020] 1. By setting an arc groove to match a rotatable elliptical shaft, when conducting a colloid adhesion test, one end of the thin plate in the honeycomb panel is inserted into the gap between the arc groove and the elliptical shaft, and the elliptical shaft is rotated to ensure that the end of the thin plate is fixed in the arc groove. Then the connecting strip is wrapped in the annular groove so that the position of the fixed part of the tensile machine corresponds to the arc groove. With the help of an external tensile machine, the output end or fixed end of the tensile machine is fixed to the other end of the thin plate. At the same time, the fixed end or output end of the tensile machine is fixed to the fixed part of the tensile machine. Then, the fixed part of the tensile machine and the end of the thin plate opposite thereto are stretched and pulled, so that the thin plate is separated from the honeycomb panel. During the separation process, the external tensile machine obtains the force required for separation to judge the adhesion of the colloid. In the above manner, when the honeycomb panel is pulled, the separation surface between the thin plate and the honeycomb panel is always at the tangent position of the roller, thereby ensuring that the direction of the force will not deviate during the pulling process, so as to ensure the accuracy of the test results of the colloid adhesion.

[0028] According to the applicant's research and analysis, in order to test the adhesion degree of the colloid, the thin plate and the honeycomb plate of the honeycomb panel are usually fixed, and then the adhesion degree of the colloid is tested by pulling with the help of an external tensile testing machine. However, in traditional situations, when fixing the thin plate and the honeycomb plate, a direct connection and fixation method is usually adopted, that is, the output end of the external tensile testing machine is directly connected to the thin plate, and the honeycomb plate of the honeycomb panel is directly connected to the fixed end of the tensile testing machine. However, in this way, the direction of the force is likely to shift as the pulling progresses, thereby affecting the test results of the tension, that is, affecting the results of the adhesion degree. Therefore, it is urgent to design a connecting tool for colloid adhesion testing so that by setting a roller structure, when the honeycomb panel is pulled, the separation surface of the thin plate and the honeycomb plate is always at the tangent position of the roller, thereby ensuring that the direction of the force will not shift during the pulling process, so as to ensure the accuracy of the test results of the colloid adhesion.
[0029] The present invention will now be described in further detail with reference to the accompanying drawings.
[0030] Combined with attachment Figure 1-6 As shown, a connecting tool for testing colloid adhesion includes a roller body 1, a disc 2, an annular groove 3, a connecting strip 4, a tensile machine fixing part 5, a fixing bolt 6, an arc groove 7, a connecting shaft 8, an elliptical shaft body 9 and a wrench part 10.
[0031] Combined with attachment Figure 1-6The present invention relates to a connecting tool for testing the adhesion of colloids, comprising: a roller body 1, a connecting strip 4, a tensile machine fixing part 5 and an elliptical shaft body 9. The roller body 1 is a circular cylindrical structure, and a disc 2 is provided on both sides of the roller body 1. The disc 2 is provided with an annular groove 3 along the arc surface, and an arc groove 7 is provided on the arc surface of the roller body 1 in the axial direction. Connecting shafts 8 are connected to the two sides of the elliptical shaft body 9. The two discs 2 are provided with a through-hole corresponding to the connecting shaft 8 at the positions corresponding to the arc groove 7. The connecting shaft 8 passes through the through-hole and is rotatably connected with the through-hole. The elliptical shaft body 9 is located in the arc groove 7, and by rotating the elliptical shaft body 9, the elliptical shaft body 9 can fit with the groove wall of the arc groove 7. The number of the connecting strips 4 is two, and one end of the two connecting strips 4 is respectively fixed in the annular groove 3 of the two discs 2 by their respective corresponding fixing bolts 6. The other end of the two connecting strips 4 is connected to the tensile machine fixing part 5. By setting the arc groove 7 to cooperate with the rotatable elliptical shaft body 9, during the test, the connecting strips 4 are connected. During the colloid adhesion test, one end of the thin plate in the honeycomb panel is inserted into the gap between the arc groove 7 and the elliptical shaft body 9. By rotating the elliptical shaft body 9, the end of the thin plate is ensured to be fixed in the arc groove 7. Then the connecting strip 4 is wrapped in the annular groove 3 so that the position of the tensile machine fixing part 5 corresponds to the arc groove 7. With the help of an external tensile machine, the output end or fixed end of the tensile machine is fixed to the other end of the thin plate. At the same time, the fixed end or output end of the tensile machine fixes the tensile machine fixing part 5. Then the tensile machine fixing part 5 and the end of the thin plate opposite to it are stretched and pulled to separate the thin plate from the honeycomb panel. During the separation process, the external tensile machine obtains the force required for separation to judge the adhesion of the colloid. In the above manner, when the honeycomb panel is pulled, the separation surface between the thin plate and the honeycomb panel is always at the tangent position of the roller, thereby ensuring that the direction of the force will not shift during the pulling process, so as to ensure the accuracy of the colloid adhesion test results.
[0032] Combined with attachment Figure 1-6 As shown, the center of the disc 2 coincides with the center of the roller body 1, the center of the annular groove 3 coincides with the center of the disc 2, and a wrench portion 10 is provided at the end of the connecting shaft 8 away from the roller body 1. The position of the fixing bolt 6 corresponds to the arc groove 7, and the length of the connecting strip 4 corresponds to the circumference of the annular groove 3. Since the center of the disc 2 coincides with the center of the roller body 1, it can be ensured that when the disc 2 rotates along the axis, the roller body 1 can synchronously rotate along the axis with the same amplitude. Since the center of the annular groove 3 coincides with the center of the disc 2, it can be ensured that when the disc 2 rotates along the axis, the annular groove 3 can synchronously rotate along the axis with the same amplitude. By providing the wrench portion 10, the connecting shaft 8 can be conveniently rotated with the help of an external wrench in combination with the wrench portion 10. Since the position of the fixing bolt 6 corresponds to the arc groove 7 and the length of the connecting strip 4 corresponds to the circumference of the annular groove 3, the stretching space of the tensile machine can be fully utilized while ensuring the stretching distance during the test.
[0033] Working principle: When in use, first insert one end of the thin plate in the honeycomb panel into the gap between the arc groove 7 and the elliptical shaft body 9, and then use the external wrench to cooperate with the wrench part 10 to rotate the connecting shaft 8, and then rotate the elliptical shaft body 9. As the elliptical shaft body 9 rotates, the thin plate can be clamped and fixed. Then the connecting strip 4 is wrapped in the annular groove 3, so that the tensile machine fixing part 5 is located in the arc groove 7 position. With the help of an external tensile machine, the fixed end of the tensile machine is fixedly connected to the tensile machine fixing part 5, and the output end of the tensile machine is fixedly connected to the other end of the thin plate, or the output end of the tensile machine is fixedly connected to the tensile machine fixing part 5, and the fixed end of the tensile machine is fixedly connected to the other end of the thin plate. Then start the tensile machine, pull the tensile machine fixing part 5 and the end of the thin plate. As the pulling progresses, the thin plate is separated from the honeycomb panel, so that the colloid adhesion can be measured by measuring the tensile force.
