Description

Technical Field

[0001] The invention relates to the field of bonding strength testing tools, in particular to a bonding strength measurement auxiliary device. Background Art

[0002] Internal bonding strength is the measurement of the tensile strength of the plate specimen surface when it is subjected to uniformly distributed tensile force until it is destroyed. The equipment used for this test is a universal testing machine. When conducting the test, the specimen needs to be pre-connected with the metal clamp by hot melt glue or epoxy resin glue. After balancing, the testing machine applies a tensile force perpendicular to the surface of the specimen through the fixture, thereby realizing the internal bonding strength experiment.

[0031] like Figure 1-8 As shown, a bonding strength measurement auxiliary device includes a testing machine base 1, a testing machine movable seat 2 and a telescopic component 3. The telescopic component 3 is located between the testing machine base 1 and one side of the testing machine movable seat 2, and the telescopic component 3 connects the two. A test sensor is installed in the telescopic component 3. The hydraulic cylinder A4 is also included. The fixed end and the movable end of the hydraulic cylinder A4 are respectively connected to the testing machine base 1 and the testing machine movable seat 2, so as to control the movement of the two.

[0032] The test machine base 1 and the test machine movable base 2 are simplified structures of existing test machines, which also include core components such as test sensors, analysis elements, control circuits and control chips that are not displayed. The telescopic assembly 3 serves as a connecting part, and its purpose is to maintain the stability of the test machine base 1 and the test machine movable base 2 during relative movement. It can also be used to hide cables and pipelines, and hydraulic generation and control equipment are also installed in the test machine base 1 to provide the power required for all hydraulic cylinders.

[0033] A disc 5 is installed on the side of the testing machine base 1 and the testing machine movable seat 2 that are away from the telescopic component 3 and close to each other. A plurality of equidistant circular array connecting components 6 are installed on the sides of the two discs 5 that are close to each other. The connecting components 6 on the two discs 5 are staggered in upper and lower positions, and the corresponding upper and lower spacings are the same, which are used to connect the test pieces. A limiting tube 7 is fixedly installed on the upper surface of the bottom disc 5, and a torsion component 8 is installed in the limiting tube 7 for torsion test of the test piece. A pressing component 9 is also installed on the bottom surface of the upper disc 5 between the connecting components 6 for pressing the test piece to be close to the connecting component 6.

[0034] The disc 5 is connected to the test machine base 1 or the test machine movable seat 2 by bolts, and the connection angle is adjustable. The connection components 6 on the upper and lower discs 5 are staggered and cross-matched at equal distances. The purpose is to avoid point overlap during connection, which will reduce the strength of the test piece structure and affect the bonding test data. The setting of the limit tube 7 is to test the annular test piece and the circular test piece, and to test the two parts of the same test piece separately. The large ring tests the tensile bonding strength, and the small circle tests the torsion strength. The test results are more scientific, the test methods are diversified, and they can better meet the needs of actual use. The pressing component 9 first contacts the test piece relative to the upper connection component 6, can change the distance between it and the disc 5, and is used to press the test piece.

[0035] The connecting assembly 6 includes a motor 601, a plane milling drill bit 602, a centrifugal cutter 603 and a control rod 604. The motor 601 is mounted on the disc 5. The plane milling drill bit 602 is connected to the output shaft of the motor 601. A slot 605 is provided at one end of the plane milling drill bit 602 away from the output shaft of the motor 601. The slot 605 is circular. It is best to set three centrifugal cutters 603, which are distributed at equal angles. The centrifugal cutter 603 is installed at the end position of the plane milling drill bit 602 and is elastically twisted relative to it. A planing groove 606 is provided on the outer circle of the end of the centrifugal cutter 603 away from the hinge point with the plane milling drill bit 602. A latch 607 is fixedly installed on the inner circle of the centrifugal cutter 603. The control rod 604 is in In the slot 605, a spring 608 is provided between the control rod 604 and the inner bottom wall of the slot 605, and the two ends of the spring 608 are respectively connected to the control rod 604 and the inner bottom wall of the slot 605. A detection rod 609 is installed on the end of the control rod 604 away from the slot 605. The control rod 604 can limit the pin 607 to close the centrifugal knife 603. After the pin 607 of the centrifugal knife 603 is not restricted by the control rod 604, it will be unfolded when it is subjected to reverse torsion force, and the length between the tip and the center of the plane milling drill bit 602 after unfolding is greater than the radius length of the plane milling drill bit 602. A grinding assembly 610 is also fixedly installed on the hinge point between the centrifugal knife 603 and the plane milling drill bit 602.

[0036] A longitudinal groove 611 is formed on the side of the control rod 604, and the latch 607 can be inserted into the longitudinal groove 611, and the two are slidably connected.

[0037] Multiple motors 601 are controlled together, and the cables controlling the motors 601 are connected to the central control components through the test machine base 1 and the test machine movable base 2. The motors 601 are connected to the disc 5 by the motor base, and the connection method is bolt connection, which can be removed and added. The plane milling drill bit 602 is modified on the basis of the existing drill bit, and the side surface of the end thereof is a normal cutting groove structure, while the slot 605 at the center position of the end thereof is an improved structure, and the control rod 604 installed in the slot 605 thereof can slide relative to it, but it cannot leave the slot 605 due to the restriction of the spring 608, and the control rod 604 can slide relative to it. 04 has a certain limit when moving upward, the centrifugal cutter 603 is an arc-shaped involute structure, and a torsion spring is installed at the hinge point between the centrifugal cutter 603 and the plane milling drill bit 602. The torsion spring is hidden and hidden in the centrifugal cutter 603. When the centrifugal cutter 603 is contracted and is within the cross-sectional area of ​​the plane milling drill bit 602, the torsion spring is in a compressed state. After the torsion spring is released, the centrifugal cutter 603 is in an expanded state. From the front view, the centrifugal cutter 603 and the plane milling drill bit 602 form a T-shaped structure, and the planing groove 606 of the centrifugal cutter 603 can be ground synchronously during rotation, and horizontal grinding can be performed. The bottom of the centrifugal knife 603 is a sloped structure. When the plane milling drill bit 602 is taken out relative to the test piece, the plane milling drill bit 602 is rotated in the opposite direction at a low speed, and at the same time, a pulling force is applied between it and the test piece. The centrifugal knife 603 will gradually close due to resistance until its latch 607 is aligned with the longitudinal groove 611 of the control rod 604. At this time, since the plane milling drill bit 602 is a certain distance away from the opening, when the control rod 604 is stretched by the reaction force of the spring 608, it can jam the latch 607, and the upper end of the longitudinal groove 611 is set to a shape that is easy for the latch 607 to enter.

[0038] The longitudinal groove 611 passes through the control rod 604. When the control rod 604 moves downward to compress the spring 608, the longitudinal groove 611 will gradually move relative to the latch 607 until the latch 607 leaves the longitudinal groove 611. At this time, the latch 607 is in a free state.

[0039] The grinding assembly 610 includes a conical disk 6101, a grinding tooth A6102 and a grinding tooth B6103. The conical disk 6101 is fixedly installed on the rotation point of the centrifugal cutter 603. The circumferential surface of the conical disk 6101 is provided with a cutting groove. There are multiple grinding teeth A6102, which are fixedly installed on the conical surface of the conical disk 6101 and arranged at equal distances. The grinding tooth B6103 is an arc milling cutter, and the grinding tooth B6103 is fixedly installed in the middle position of the tip of the conical disk 6101.

[0040] The grinding assembly 610 provides radial grinding, and can gradually perform hole opening operations when the plane milling drill bit 602 is grinding and feeding. The three cone disks 6101 work together to achieve high hole opening efficiency. The grinding teeth A 6102 and the grinding teeth B 6103 improve the grinding efficiency and can extend the replacement cycle.

[0041] The limiting tube 7 is located at the center of the disk 5 , and the two are concentrically arranged. The connecting assembly 6 is located in a circle outside the limiting tube 7 , and the center point of the surrounding of multiple connecting assemblies 6 is at the center point of the limiting tube 7 .

[0042] The connecting assembly 6 is located in the middle of the distance between the outer wall of the limiting tube 7 and the outer wall of the disk 5 .

[0043] The torsion assembly 8 includes a hydraulic press 801 and a chuck 802. The chuck 802 is provided with two groups. The upper chuck 802 is fixed to the inner wall of the limiting tube 7. The output shaft of the hydraulic press 801 is installed with a torsion plate 803. The lower chuck 802 is connected to the torsion plate 803. The hydraulic press 801 can twist the torsion plate 803.

[0044] The hydraulic press 801 can be a large-torque hydraulic motor or a torsional action achieved by a double hydraulic cylinder in cooperation with a crank slider component, which mainly provides a torsional force to the torsion plate 803. In addition, a torque sensor and a resistance sensor are installed inside the hydraulic press 801 to test the resistance curve.

[0045] The chuck 802 includes a hydraulic cylinder B8021 and a clamping block 8022. The hydraulic cylinder B8021 included in the upper chuck 802 is fixed to the inner wall of the limiting tube 7, and the hydraulic cylinder B8021 included in the lower chuck 802 is fixed to the upper surface of the torsion plate 803. A group of chucks 802 includes multiple hydraulic cylinders B8021, which are distributed in a circular array. The clamping block 8022 is fixed on the output shaft of the hydraulic cylinder B8021 and is located in the inner circle surrounded by the hydraulic cylinder B8021.

[0046] The chuck 802 is similar to the existing three-jaw chuck of a machine tool, and the cut center specimen can be placed in it. The upper and lower chucks 802 need to fix the upper and lower parts of the time respectively. The fixing distance between the two is preferably the same, or they can be fixed separately with a glue line for accurate testing of the bonding strength curve.

[0047] The pressing assembly 9 includes a pressing arm 901, a hydraulic cylinder C902 and a friction wheel 903. One end of the pressing arm 901 is hinged to the bottom surface of the upper disc 5, one end of the hydraulic cylinder C902 is hinged to the disc 5, the output end of the hydraulic cylinder C902 is hinged to the middle position of the pressing arm 901, the friction wheel 903 is installed on the end of the pressing arm 901 away from the disc 5 and is rotatably connected thereto, and the pressing arm 901 is inclined relative to the disc 5.

[0048] When the hydraulic cylinder C902 is extended and contracted, it can realize various actions of the pressing arm 901. The friction wheel 903 of the pressing arm 901 is mainly in contact with the specimen, which can reduce the friction between the specimen and the specimen and protect the surface of the specimen. It can also be used when facing thinner specimens. The hydraulic cylinder C902 of the pressing component 9 needs to cooperate with the hydraulic cylinder A4 when being controlled. The two work together dynamically to better press down and fix the specimen.

[0049] When in use: the test piece, such as plywood, needs to be cut into a circle, which is equal to the size of the disc 5, and then the middle part is cut off to form a ring, the inner hole diameter of which is larger than the diameter of the limiting tube 7, which is used to be sleeved on the limiting tube 7, and the part cut off at the middle part is ground into a circle and placed in the limiting tube 7. When the upper disc 5 moves down, the pressing arm 901 and the hydraulic cylinder C902 included in the pressing assembly cooperate to press the annular test piece down to the bottom connection assembly 6, so that the test piece contacts the bottom connection assembly 6 and cooperates with the bottom connection assembly 6;

[0050] When connected: the motor 601 drives the plane milling drill 602 to rotate when rotating, and then drives the three grinding assemblies 610 to rotate. When in contact with the test piece, the test piece is continuously in contact with the grinding assembly 610. The grinding assembly 610 can grind the test piece to make a hole, and there is a gap between the three grinding assemblies 610. The detection rod 609 is in the gap. When grinding into the inside of the test piece, a convex cylinder is formed in the middle part that is not ground, and then the detection rod 609 is pushed to compress the control rod 604, so that the control rod 604 is pressed toward the plane milling drill. When the drill bit 602 moves inside, the longitudinal groove 611 slowly leaves the latch 607, and finally loses the restriction on the centrifugal cutter 603. After the centrifugal cutter 603 loses the restriction, it is expanded by the reaction force of the torsion spring, and the tip of the cutter contacts the inner wall of the opening. At this time, the opening is no longer fed. During the rotation of the surface milling drill bit 602, the centrifugal cutter 603 gradually expands, so that the opening forms a T-shaped hole, so that the surface milling drill bit 602 is not easy to be pulled out of the test piece. Then the connecting assembly 6 on the upper disc 5 performs the same work, so that the upper and lower surfaces of the test piece are connected.

[0051] The first part of the test: the hydraulic cylinder A4 extends, so that the two discs 5 stretch the specimen to test the bonding strength;

[0052] The second part of the test: The test piece in the test tube is fixed by two sets of chucks 802, and then when the hydraulic press 801 drives the torsion plate 803 to twist, the deformation of the test piece is detected to obtain the bonding strength.

[0053] When dealing with test pieces of different thicknesses, the specifications of the detection rod 609 can be changed, and detection rods 609 of different lengths can be replaced, so as to ensure that the control rod 604 can release the centrifugal knife 603 when feeding at different depths.

[0054] When it is necessary to release the connection between the surface milling drill bit 602 and the test piece, the surface milling drill bit 602 is rotated in the reverse direction at a low speed and a pulling force is applied to make the centrifugal knife 603 slowly close after encountering resistance, and then the pin 607 returns to the control rod 604 again, thereby achieving separation.
