Description

Technical Field

[0001] This utility model relates to the field of insulation board strength technology, specifically a composite insulation board strength testing device. Background Technology

[0002] Composite insulation board, simply put, is a board used for building insulation. It's a rigid foam plastic board made from polystyrene resin, along with other raw materials and polymers. The mixture is heated and mixed while a catalyst is injected, then extruded and molded. It has moisture-proof and waterproof properties, allowing for a reduction in the thickness of the building's external envelope, thus increasing usable indoor space.

[0003] To ensure the quality and safety of the insulation board during use, its strength needs to be tested after the insulation board is manufactured. Therefore, a corresponding strength testing device is required.

[0004] Chinese patent application number 202320184368.2 discloses a thermal insulation board strength testing device, including a base, a thermal insulation board support, a support column, a support plate, a T-shaped plate, a second support plate, and a hydraulic cylinder mechanism. The thermal insulation board support is mounted on top of the base, and the support column connects the base to the support plate. A lead screw is installed between the support plate and the base, and the lead screw and support column are respectively connected to the T-shaped plate. A motor and a housing are mounted on the support plate, and the motor's power shaft is connected to the lead screw. The hydraulic cylinder mechanism, the ball-dropping impact mechanism, and the motor controller are located inside the housing. One end of the vertical plate of the T-shaped plate is connected to the second support plate, and the hydraulic cylinder mechanism and the ball-dropping impact mechanism are installed at both ends of the second support plate. The thermal insulation board is placed on the thermal insulation board support. This invention can not only perform compression tests on thermal insulation boards but also conduct ball-dropping impact tests. After the impact test, the ball can be automatically retrieved, avoiding the inconvenience of manual retrieval by operators, making the overall device more efficient, flexible, and convenient.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-5 As shown, this utility model provides a technical solution: including a machine tool assembly 1, wherein a clamping pressure testing assembly 2 and a strength testing assembly 3 are respectively provided in the front and rear parts of the machine tool assembly 1;

[0024] The clamping pressure testing assembly 2 includes a U-shaped plate 201. A first hydraulic cylinder 205 is fixedly installed in the middle of the top surface of the U-shaped plate 201. A square groove is opened on the front side of the U-shaped plate 201. Concave plates 206 are provided at the top and bottom of the square groove. The concave plate 206 at the bottom is fixedly installed on the bottom surface of the square groove. The concave plate 206 at the top is slidably installed in the square groove. The middle of the top surface of the concave plate 206 at the top is fixedly connected to the bottom end of the piston rod of the first hydraulic cylinder 205. Grooves are opened on opposite sides of the two concave plates 206. A clamping plate 208 is slidably installed in each groove. A second cylinder 207 is fixedly installed in the middle of the front side of each concave plate 206. The piston rod of the second cylinder 207 is fixedly connected to the front side of the clamping plate 208.

[0025] The strength testing component 3 includes a second linear motor 301. A third linear motor 302 is fixedly installed on one side of the slider of the second linear motor 301. An installation block 303 is fixedly installed on the top surface of the slider of the third linear motor 302. A second hydraulic cylinder 304 is fixedly embedded in the middle of the back side of the installation block 303. A pressure testing head 305 is fixedly installed on one end of the piston rod of the second hydraulic cylinder 304.

[0026] In this embodiment, the machine tool assembly 1 includes a machine base 101. A baffle plate 102 is fixedly installed on the top surface of the machine base 101. A baffle door plate 103 is hinged to one side of the front of the baffle plate 102. A locking threaded hole 105 is opened in the middle of the other side of the front of the baffle plate 102. A locking screw 104 is threaded into the middle of one side of the front of the baffle door plate 103. By threading the locking screw 104 into the corresponding locking threaded hole 105, the opening on the front of the baffle plate 102 can be sealed, preventing debris from flying everywhere during the testing of the composite insulation board.

[0027] The guide plate 201 is fixedly installed on the front top of the base 101, and the second linear motor 301 is fixedly installed on the rear side of the top surface of the base 101.

[0028] A linear motor 202 is provided on one side of the U-shaped plate 201. A cylinder 203 is fixedly installed on the front of one side of the slider of the linear motor 202. One end of the piston rod of the cylinder 203 passes through the inner side of the slider of the linear motor, and a retaining plate 204 is fixedly installed on the end through which the piston rod of the cylinder 203 passes. The retaining plate 204 is controlled to rise and fall and be positioned in the middle of the side of the composite insulation board. Then the cylinder 203 is activated. Under the action of the cylinder 203, the retaining plate 204 moves and will block the other side of the composite insulation board to be tested, thereby preventing the composite insulation board from shifting laterally during the test.

[0029] In use, activate cylinder 207 at the bottom. Cylinder 207 moves clamping plate 208, which changes the gap between the back of clamping plate 208 and the back of the groove on the top surface of concave plate 206. This gap is adjusted to match the thickness of the composite insulation board being tested. After adjustment, remove the composite insulation board to be tested and insert it vertically between the clamping plate 208 and the groove on concave plate 206, ensuring one side of the composite insulation board is in contact with one side of the square groove. After the board is inserted, linear motor 202 controls cylinder 203 and the lifting plate 204 to raise and lower. Located at the center of the side of the composite insulation board, cylinder 203 is then activated. Under the action of cylinder 203, the retaining plate 204 moves and abuts against the other side of the composite insulation board to be tested, thus preventing lateral displacement of the composite insulation board during the test. After lateral fixation is completed, hydraulic cylinder 205 is activated. Under the action of hydraulic cylinder 205, the concave plate 206 at the top descends. After the concave plate 206 at the top is inverted and placed on the top of the composite insulation board, cylinder 207 at the top is activated. Cylinder 207 at the top controls the clamping plate 208 to move and clamp the top of the composite insulation board. Through the above operations, composite insulation boards of different sizes can be easily clamped and fixed.

[0030] After the composite insulation board is installed, its strength can be tested. The third linear motor 302 can be raised and lowered via the second linear motor 301. The raising and lowering of the third linear motor 302, in turn, raises and lowers the second hydraulic cylinder 304 and the pressure testing head 305. The third linear motor 302 can control the lateral displacement of the second hydraulic cylinder 304 and the pressure testing head 305. Through these operations, the second hydraulic cylinder 304 and the pressure testing head 305 can be easily moved to various positions. The second hydraulic cylinder 304 controls the pressure testing head 305 to perform compression tests on various points on the surface of the insulation board. Simultaneously, the first hydraulic cylinder 205 can lower the top concave plate 206 to test the vertical load-bearing strength of the vertically placed composite insulation board, providing a more comprehensive testing approach.

[0031] In summary, this composite insulation board strength testing device can be adapted to the size of the composite insulation board to be tested, making it easy to clamp and fix composite insulation boards of different sizes, and with stronger stability. It can effectively prevent the composite insulation board from shifting during the test. At the same time, it can easily control the movement of the second hydraulic cylinder 304 and the pressure test head 305 to various positions, and control the pressure test head 305 to perform compression tests on various positions on the surface of the insulation board through the second hydraulic cylinder 304, making the test data more comprehensive. In addition, the first hydraulic cylinder 205 can drive the concave plate 206 at the top to descend, so as to test the vertical load-bearing strength of the vertically placed composite insulation board. The testing direction is more comprehensive and the functionality is stronger.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
