Description

Technical Field

[0001] The utility model belongs to the technical field of plate detection, and in particular relates to a plate bonding strength detection device. Background Art

[0002] Multi-layer structured panels are usually made of multiple layers of thin panels stacked and bonded together with glue. The bonding strength determines the safety and long-term stability of the panels, so it is necessary to test the bonding strength of the panels. The existing technical measure is to clamp the two ends of the processed test piece in a pair of movable clamps of the testing machine to form a straight line, and then move the two movable clamps away from each other in the straight line direction until the test piece is destroyed.

[0003] A Chinese patent with publication number CN211235476U discloses a wood gluing strength testing machine, which includes two transverse tubes and a computer. The above scheme uses motors fixedly connected to the right sides of the two transverse tubes, a forward threaded rod fixedly connected to the output end of the motor, and a reverse threaded rod fixedly connected to the left side of the forward threaded rod. Threaded sleeves are sleeved on the surfaces of the forward threaded rod and the reverse threaded rod, and the two threaded sleeves are respectively connected to a tensile gauge and a positioning frame, which solves the problem that the existing testing machine can only test one group of test pieces at a time.

[0004] When the above scheme is in use, since the two horizontal tubes are arranged facing each other, the experimenter must install the two test pieces respectively between the two horizontal tubes. The operating space is small, which makes it inconvenient for the experimenter to install the test pieces. At the same time, since the two horizontal tubes are arranged at intervals along the vertical direction, the overall center of gravity of the above scheme is relatively high, which is prone to tipping. Utility Model Content

[0005] The utility model aims to provide a plate bonding strength detection device to solve the problems of small operating space and high center of gravity in the above-mentioned solution.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A plate bonding strength detection device includes a frame body, the frame body has an installation cavity, and the top of the installation cavity is open, a force measuring assembly is arranged in the installation cavity along the left and right directions, a computer is fixedly arranged on the front wall of the frame body, the force measuring assembly includes a bidirectional threaded rod, a motor and a slider, the bidirectional threaded rod is rotatably penetrated in the frame body, the motor is fixedly arranged on the side wall of the frame body, and the output shaft of the motor is fixedly connected to the bidirectional threaded rod, two sliders are arranged, both of which are slidably arranged on the top of the bottom wall of the installation cavity, and the two sliders are respectively cooperated and sleeved on the positive and negative thread sections of the bidirectional threaded rod, a mounting plate is fixedly arranged at one end of the top of the two sliders away from each other, a tension sensor is respectively arranged on the side of the two installation plates close to each other, and a clamping assembly is respectively arranged at one end of the two tension sensors close to each other, the force measuring assembly is arranged in multiple groups at intervals along the front and rear directions, the computer is electrically connected to multiple pressure sensors through signal lines, and the computer is electrically connected to multiple motors.

[0008] The principle and effect of this technical solution:

[0009] During use, the inspector drives the motor to rotate the bidirectional threaded rod according to the length of the test piece. Since the bottom wall of the installation cavity limits the rotation of the slider, the slider moves with the rotation of the bidirectional threaded rod, thereby moving the two sliders to the predetermined positions. Then, the two ends of the test piece are clamped on the two clamping assemblies respectively, and the motor is driven again to rotate the bidirectional threaded rod to make the two sliders move away from each other until the test piece is destroyed. The tension sensor transmits the maximum load value to the computer through the signal line.

[0010] Through the above arrangement, multiple force measuring components are arranged at intervals in the lateral direction, which, on the one hand, expands the operating space and facilitates the inspectors to clamp the test piece in the clamping component, and on the other hand, lowers the center of gravity of the utility model to avoid tipping.

[0011] In the utility model, the clamping assembly includes a U-shaped plate, a clamping plate and a hydraulic rod. The clamping plate is located inside the U-shaped plate, the hydraulic rod is fixedly arranged on the rear wall of the U-shaped plate, and one end of the hydraulic rod passes through the rear wall of the U-shaped plate and extends into the U-shaped plate. One end of the hydraulic rod extends into the U-shaped plate and is fixedly connected to the clamping plate.

[0012] Through the above arrangement, it is convenient for the inspector to clamp the piece to be tested, thereby improving the practicality of the utility model.

[0013] In the utility model, both left and right ends of the tension sensor are recessed with threaded holes, the mounting plate is provided with a first through hole that cooperates with the threaded hole, the first fastening bolt is passed through the first through hole and inserted into the threaded hole, the side wall of the U-shaped plate is provided with a second through hole, the second fastening bolt is passed through the second through hole and inserted into the threaded hole.

[0014] In the utility model, a notch matching with the U-shaped plate is arranged on the top of the sliding block away from the mounting plate, and the bottom of the U-shaped plate abuts against the top of the notch.

[0015] The principle and effect of this technical solution:

[0016] Pass the first fastening bolt through the first through hole and fit into the threaded hole to fix the tension sensor on the mounting plate, then pass the second fastening bolt through the second through hole and fit into the threaded hole to fix the U-shaped plate on the tension sensor, at which point the bottom of the U-shaped plate abuts against the top of the notch.

[0017] Through the above arrangement, since the notch limits the rotation of the U-shaped plate, it is possible to avoid the rotation of the two U-shaped plates facing each other during the experiment, thereby causing the test piece to twist, thereby improving the accuracy of the test result of the utility model.

[0018] In the utility model, a limiting groove is recessed on the side wall of the U-shaped plate away from the tension sensor, and a limiting block matching the limiting groove is arranged on the side of the clamping plate close to the tension sensor, and the limiting block is slidably embedded in the limiting groove.

[0019] In the present invention, the second fastening bolt is provided with a bolt cap, a countersunk hole matching with the bolt cap is recessed in the limiting groove, and the top of the bolt cap is flush with the side wall of the limiting groove.

[0020] Through the above arrangement, the clamping plate can be prevented from rotating along the axial direction of the hydraulic rod, ensuring that the clamping assembly can clamp the test piece.

[0021] In the present invention, a partition plate is provided between adjacent force measuring components, and the left and right ends of the partition plate are respectively inserted vertically into the inner side wall of the installation cavity, and a wire groove is recessed at the top of the bottom wall of the installation cavity below the partition plate, and the wire groove is used to bury the signal line. Through the above arrangement, the length of the exposed signal line can be reduced, the slider can be prevented from squeezing the signal line during the sliding process, and the service life of the present invention can be extended.

[0022] In the utility model, a protective cover is rotatably connected to one end of the top of the frame body. Through the above arrangement, it is possible to prevent the inspector from being injured by the flying wood chips when the test piece is damaged, thereby improving the safety of the utility model.
