Description

Technical Field

[0001] The invention relates to the technical field of thermal insulation board strength testing equipment, and in particular to a composite thermal insulation board strength testing device. Background Art

[0002] As the name suggests, the insulation board strength testing equipment refers to equipment for testing the impact strength of insulation boards. After placing the insulation board on the machine, the insulation board is impacted and squeezed by sensors, and then the data is transmitted to the computer for integration with the help of sensors to obtain the insulation board strength parameters.

[0003] When testing the strength of a composite insulation board, the composite insulation board needs to be placed on a machine for testing. However, traditional testing equipment has a poor limiting effect on the insulation board. When the sensor impacts the insulation board, the insulation board is prone to move, which in turn causes the impacted position to change, causing a certain impact on the test results. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings in the prior art that the insulation board is easy to move, which in turn causes the impact position to change and has a certain impact on the test result, and to propose a composite insulation board strength testing device.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a composite insulation board strength testing device, including a machine platform, a manipulator is fixedly connected to the upper end of the machine platform, a sensor is installed on the surface of the manipulator, a limiting structure is provided on the upper surface of the machine platform, and the limiting structure includes two slide rails, the two slide rails are fixedly connected to the upper surface of the machine platform, the inner walls of the slide rails are slidably connected with sliders, the two sliders are internally threaded with driving rods, opposite threads are provided at both ends of the driving rod, and triangular frames are threadedly connected to the two ends of the driving rod, a screw is threadedly inserted on the upper surface of the triangular frame, and a pressure plate is rotatably connected to the lower end of the screw. By adopting this technical scheme, the effect of quickly fixing the insulation board to be tested on the machine platform is achieved, and the positions of the two triangular frames can be adjusted according to the specific size of the insulation board, thereby achieving the effect of improving the fixing adaptability of the machine platform to insulation boards of different sizes.

[0006] Preferably, an anti-skid pad is fixedly connected to the side of the pressing plate away from the screw, the size of the anti-skid pad is matched with the size of the pressing plate, and the anti-skid pad is a rubber pad. By adopting this preferred scheme, the effect of increasing the friction between the pressing plate and the insulation plate is achieved, thereby increasing the fixing strength of the pressing plate to the insulation plate.

[0007] Preferably, both inner walls of the triangular frame are provided with limiting grooves, the inner walls of the limiting grooves are slidably connected to limiting blocks, and the two limiting blocks are fixedly connected to the pressure plate on one side away from the inner walls of the limiting grooves. By adopting this preferred scheme, the effect of limiting the moving position of the pressure plate is achieved, thereby preventing the pressure plate from rotating when the screw drives the pressure plate.

[0008] Preferably, one end of the driving rod is fixedly connected to a handle, and the cross-section of the handle is "Z"-shaped. By adopting this preferred solution, the driving rod can be easily and quickly rotated, thereby quickly driving the two triangular frames to move.

[0009] Preferably, a traction structure is provided on the side of the machine close to the manipulator, and the traction structure includes a support frame, the support frame is fixedly connected to the upper surface of the machine, and the support frame is slidably connected to two adjustment blocks on the side away from the machine, and the sides of the two adjustment blocks close to each other are fixedly connected with a spring, and the side of the adjustment block away from the support frame is rotatably connected with a rotating plate, and the ends of the two rotating plates close to each other are rotatably connected with a buckle, and a fastening nut is threadedly inserted on the upper surface of the buckle. By adopting this technical solution, the effect of quickly adjusting the position of the insulation board relative to the machine is achieved, thereby facilitating the inspection personnel to use the equipment to inspect different positions of the insulation board.

[0010] Preferably, a telescopic rod is fixedly connected to one side of the two adjustment blocks that are close to each other, and the arc surface of the telescopic rod is slidably connected to the spring. By adopting this preferred scheme, the effect of limiting the direction of the spring elastic force is achieved, thereby limiting the moving position of the two adjustment blocks.

[0011] Preferably, two fixing plates are fixedly connected to one side of the support frame close to the adjustment block, a screw rod is threadedly connected to the inner surface of the fixing plate, and the cross-section of the screw rod is "T"-shaped.

[0012] Preferably, the ends of the two screw rods that are close to each other are fixedly connected with a ball, and the ball is a solid iron ball with a polished surface. By adopting this preferred solution, the friction between the screw rod and the adjusting block is reduced, so that the screw rod can better push the adjusting block.

[0013] Preferably, the arc surface of the driving rod is provided with a cleaning structure, and the cleaning structure includes two bearings, the inner rings of the two bearings are fixedly connected to the driving rod, the outer rings of the two bearings are fixedly connected with a rectangular plate, and the side of the rectangular plate away from the bearing is fixedly connected with a cleaning pad, and the cleaning pad is located above the machine. By adopting this technical solution, the effect of simply cleaning the surface of the machine is achieved, which is mainly used to clean the debris generated after the unqualified insulation board is impacted and broken, thereby avoiding the debris from affecting the normal inspection of other insulation boards.

[0014] Preferably, the arc surface of the driving rod is rotatably connected to a plastic bottle, one end of the plastic bottle is threadedly connected to a bottle cap, the arc surface of the plastic bottle is connected to a conduit, and the end of the conduit away from the plastic bottle slides through the rectangular plate and is connected to the cleaning pad. By adopting this preferred scheme, the cleaning liquid can be dripped onto the cleaning pad to further clean the machine and improve the cleanliness of the equipment.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are:

[0016] When the two triangular frames are moved to the appropriate position, the driving rod is stopped and the rotation of the driving rod is performed, and then the two triangular frames are placed between the two triangular frames, and then the handle is reversed so that the driving rod drives the two triangular frames to move towards each other with the help of the thread. At this time, the two triangular frames will be stuck in the two corners of the thermal insulation board, and then the thermal insulation board is fixed in the two triangular frames, and then the manipulator is started to use the sensor to perform impact detection on the thermal insulation board. By setting the limiting structure, the effect of enabling the machine to quickly clamp and fix thermal insulation boards of different sizes is achieved, so that it is convenient for the sensor to perform impact detection on a certain position of the thermal insulation board.

[0017] 2. In the present invention, a screw is set, and when the insulation board needs to be fixed in the triangular frame, the insulation board is first placed in the triangular frame and under the pressing plate, and then the screw is rotated. The screw drives the pressing plate to move downward with the help of the thread. The downward movement of the pressing plate will drive the two limit blocks to move, and the two limit blocks will slide downward along the inner wall of the limit groove. The limit groove has the effect of limiting the moving position of the pressing plate. The downward movement of the pressing plate will drive the anti-skid pad to move downward, and the anti-skid pad will contact the surface of the insulation board. The anti-skid pad increases the friction between the pressing plate and the insulation board, thereby improving the fixing strength of the pressing plate to the insulation board.

[0018] 3. In the present invention, by setting a traction structure, after the insulation board is limited by the limiting structure, when the specific special size position of the insulation board needs to be detected, the insulation board is clamped in the buckle, and the fastening nut is rotated so that the fastening nut squeezes the insulation board in the buckle with the help of the thread, thereby achieving the effect of fixing the insulation board in the buckle, and then the two screw rods are rotated so that the screw rods drive the balls to move with the help of the threads, and the two balls move in the direction of approaching each other. The two balls push the two adjustment blocks to move in the direction of approaching each other, and the movement of the adjustment blocks will drive the rotating plates to rotate. The rotation of the two rotating plates starts to push the buckle to move. At this time, the spring will be in a compressed state, and the telescopic rod plays a role in the elasticity of the spring. The direction of the force is limited. The buckle will drive the insulation board to move at this time, so as to achieve the effect of fine-tuning the position of the insulation board. When the insulation board needs to be moved to its original position, the screw rod is reversed, and the screw rod drives the ball to move away from the adjusting block. At this time, the spring will give elastic force to the two adjusting blocks, so that the adjusting blocks are always in contact with the ball. When the ball moves, the two adjusting blocks will also move away from each other. The adjusting blocks drive the buckle to move to the original position with the help of the rotating plate, and the buckle drives the insulation board to reset. By setting the traction structure, the effect of facilitating the inspection personnel to inspect the specific size position of the insulation board is achieved, thereby improving the inspection accuracy and practicality of the entire equipment.

[0019] 4. In the present invention, by setting a cleaning structure, when it is necessary to clean the surface of the machine, first open the bottle cap of the plastic bottle, then put the cleaning liquid into the plastic bottle, then tighten the bottle cap with the help of a thread, and then press the plastic bottle to allow the cleaning liquid in the plastic bottle to flow onto the cleaning pad with the help of a conduit. When the traction structure is used to drive the driving rod to move, the driving rod drives the bearing to move, the bearing drives the rectangular plate to move, and the rectangular plate drives the cleaning pad to move. The movement of the cleaning pad will clean the surface of the machine, wherein the bearing does not affect the position of the rectangular plate without affecting the normal rotation of the driving rod. By setting the cleaning structure, the effect of facilitating and quickly cleaning the surface of the machine is achieved, thereby avoiding the situation where the waste chips generated by the impact and fragmentation of unqualified insulation boards are inconvenient to clean, which affects the detection of other insulation boards.

[0029] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0031] Embodiment 1, as Figure 1-8 As shown, the present invention provides a composite insulation board strength testing device, including a machine platform 1, a manipulator 2 is fixedly connected to the upper end of the machine platform 1, a sensor 3 is installed on the surface of the manipulator 2, a limiting structure 4 is provided on the upper surface of the machine platform 1, a traction structure 5 is provided on the side of the machine platform 1 close to the manipulator 2, and a cleaning structure 6 is provided on the arc surface of the driving rod 43.

[0032] The specific arrangement and functions of the limiting structure 4, the traction structure 5 and the cleaning structure 6 are described in detail below.

[0033] like Figure 3 and Figure 4 As shown, the limiting structure 4 includes two slide rails 41, and the two slide rails 41 are fixedly connected to the upper surface of the machine platform 1. The inner wall of the slide rail 41 is slidably connected with a slider 42. The two sliders 42 are internally threaded with a driving rod 43. Opposite threads are provided at both ends of the driving rod 43. The two ends of the driving rod 43 are threadedly connected with a triangular frame 44. A screw 45 is threadedly inserted into the upper surface of the triangular frame 44. The lower end of the screw 45 is rotatably connected with a pressing plate 46. By adopting this technical solution, the effect of quickly fixing the insulation board to be tested on the machine platform 1 is achieved, and the positions of the two triangular frames 44 can be adjusted according to the specific size of the insulation board, thereby achieving the effect of improving the fixing adaptability of the machine platform 1 to insulation boards of different sizes. The side of the pressing plate 46 away from the screw 45 is fixedly connected with an anti-skid pad 47, and the size of the anti-skid pad 47 is similar to that of the pressing plate 46 is adapted to the size, and the anti-skid pad 47 is a rubber pad. By adopting this preferred solution, the effect of increasing the friction between the pressure plate 46 and the insulation board is achieved, thereby improving the fixing strength of the pressure plate 46 to the insulation board. The two inner walls of the triangular frame 44 are provided with limiting grooves 48, and the inner walls of the limiting grooves 48 are slidably connected to limiting blocks. The two limiting blocks are fixedly connected to the pressure plate 46 on one side away from the inner wall of the limiting groove 48. By adopting this preferred solution, the effect of limiting the moving position of the pressure plate 46 is achieved, thereby avoiding the rotation of the pressure plate 46 when the screw 45 drives the pressure plate 46. One end of the driving rod 43 is fixedly connected to a handle 49, and the cross-section of the handle 49 is "Z"-shaped. By adopting this preferred solution, the effect of facilitating and quickly rotating the driving rod 43 is achieved, thereby quickly driving the two triangular frames 44 to move.

[0034] The effect achieved by the entire limiting structure 4 is that when the insulation board needs to be fixed on the machine table 1, the two sliders 42 are directly pulled, so that the slider 42 drives the driving rod 43 to slide along the inner wall of the slide rail 41. When the driving rod 43 moves to the appropriate position, the handle 49 is turned, and the handle 49 drives the driving rod 43 to rotate. The driving rod 43 drives the two triangular frames 44 to move away from each other with the help of the opposite threads at both ends, thereby achieving the effect of adjusting the distance between the two triangular frames 44. When the two triangular frames 44 move to the appropriate position, the driving rod 43 is stopped from rotating, and then the insulation board is placed between the two triangular frames 44, and then the handle 49 is reversed, so that the driving rod 43 drives the two triangular frames 44 to move towards each other with the help of the threads. At this time, the two triangular frames 44 will be stuck in the two corners of the insulation board, and then the insulation board is fixed in the two triangular frames 44, and then the manipulator 2 is started to use the sensor 3 to The insulation board is subjected to impact detection. By setting the limit structure 4, the machine 1 can quickly clamp and fix the insulation boards of different sizes, thereby facilitating the sensor 3 to perform impact detection on a certain position of the insulation board. When the insulation board needs to be fixed in the triangular frame 44, the insulation board is first placed in the triangular frame 44 and placed under the pressure plate 46, and then the screw 45 is rotated. The screw 45 drives the pressure plate 46 to move downward with the help of the thread. The downward movement of the pressure plate 46 will drive the two limit blocks to move, and the two limit blocks will slide downward along the inner wall of the limit groove 48. The limit groove 48 has the effect of limiting the moving position of the pressure plate 46. The downward movement of the pressure plate 46 will drive the anti-skid pad 47 to move downward, and the anti-skid pad 47 will contact the surface of the insulation board. The anti-skid pad 47 increases the friction between the pressure plate 46 and the insulation board, thereby improving the fixing strength of the pressure plate 46 to the insulation board.

[0035] like Figure 5 and Figure 6As shown, the traction structure 5 includes a support frame 51, which is fixedly connected to the upper surface of the machine platform 1. The support frame 51 is slidably connected to two adjustment blocks 54 on the side away from the machine platform 1. The two adjustment blocks 54 are fixedly connected to a spring 55 on the side close to each other. The adjustment block 54 is rotatably connected to a rotating plate 53 on the side away from the support frame 51. The ends of the two rotating plates 53 close to each other are rotatably connected to a buckle 52. A fastening nut 57 is threadedly inserted on the upper surface of the buckle 52. By adopting this technical solution, the effect of quickly adjusting the position of the insulation board relative to the machine platform 1 is achieved, so that it is convenient for the inspection personnel to use the equipment to inspect different positions of the insulation board. The two adjustment blocks 54 are fixedly connected to a telescopic rod 56 on the side close to each other. The arc surface of the telescopic rod 56 is connected to the spring 55 is a sliding connection. By adopting this preferred solution, the effect of limiting the direction of the elastic force of the spring 55 is achieved, thereby limiting the moving position of the two adjusting blocks 54. Two fixing plates 58 are fixedly connected to one side of the support frame 51 close to the adjusting block 54. The fixing plate 58 is internally threaded with a screw 59. The cross-section of the screw 59 is "T"-shaped. By adopting this preferred solution, the effect of pushing the adjusting block 54 to a certain position is achieved, eliminating the need for the operator to continuously press the two adjusting blocks 54. The ends of the two screws 59 close to each other are fixedly connected with a ball, which is a solid iron ball with a polished surface. By adopting this preferred solution, the effect of reducing the friction between the screw 59 and the adjusting block 54 is achieved, so that the screw 59 can better push the adjusting block 54.

[0036] The effect achieved by the entire traction structure 5 is that, by setting the traction structure 5, after the insulation board is limited by the limiting structure 4, when the specific special size position of the insulation board needs to be detected, the insulation board is clamped in the buckle 52, and the fastening nut 57 is rotated so that the fastening nut 57 squeezes the insulation board in the buckle 52 with the help of the thread, thereby achieving the effect of fixing the insulation board in the buckle 52, and then the two screw rods 59 are rotated so that the screw rods 59 drive the balls to move with the help of the threads, and the two balls move in a direction close to each other, and the two balls push the two adjustment blocks 54 to move in a direction close to each other, and the movement of the adjustment blocks 54 will drive the rotating plate 53 to rotate, and the two rotating plates 53 rotate to start pushing the buckle 52 to move, at which time the spring 55 will be in a compressed state, and the telescopic rod 56 starts to move. The effect of limiting the direction of the elastic force of the spring 55 is achieved. The buckle 52 will drive the insulation board to move at this time, thereby achieving the effect of fine-tuning the position of the insulation board. When the insulation board needs to be moved to the original position, the screw rod 59 is reversed, and the screw rod 59 drives the ball to move away from the adjusting block 54. At this time, the spring 55 will give elastic force to the two adjusting blocks 54, so that the adjusting blocks 54 are always in contact with the ball. When the ball moves, the two adjusting blocks 54 will also move away from each other. The adjusting block 54 drives the buckle 52 to move to the original position with the help of the rotating plate 53, and the buckle 52 drives the insulation board to reset. By setting the traction structure 5, the effect of facilitating the inspection personnel to inspect the specific size position of the insulation board is achieved, thereby improving the inspection accuracy and practicality of the entire equipment.

By adopting this preferred solution, the cleaning liquid can be dripped onto the cleaning pad 63, the machine 1 is further cleaned, and the cleanliness of the equipment is improved.

[0038] The effect achieved by the entire cleaning structure 6 is that by setting the cleaning structure 6, when it is necessary to clean the surface of the machine 1, first open the bottle cap of the plastic bottle 64, then fill the cleaning liquid into the plastic bottle 64, then tighten the bottle cap with the help of the thread, and then press the plastic bottle 64, so that the cleaning liquid in the plastic bottle 64 flows to the cleaning pad 63 with the help of the conduit 65, and when the traction structure 5 is used to drive the driving rod 43 to move, the driving rod 43 drives the bearing 61 to move, the bearing 61 drives the rectangular plate 62 to move, and the rectangular plate 62 drives the cleaning pad 63 to move, and the movement of the cleaning pad 63 will clean the surface of the machine 1, wherein the bearing 61 does not affect the position of the rectangular plate 62 without affecting the normal rotation of the driving rod 43. By setting the cleaning structure 6, the effect of facilitating the rapid cleaning of the surface of the machine 1 is achieved, thereby avoiding the situation in which the waste generated by the impact and fragmentation of unqualified insulation boards is inconvenient to clean, affecting the detection of other insulation boards.
