Description

Technical Field

[0001] This utility model relates to the field of test bench technology, specifically an adjustable new material research and development test bench. Background Technology

[0002] New material research and development is the core driving force for modern scientific and technological progress and industrial upgrading. Its process is highly dependent on experimental equipment that can accurately simulate and control process parameters. According to CN221803704U, an adjustable new material research and development test bench is disclosed. This technology discloses a technical solution including "a workbench, with support columns fixedly connected to both sides of the top of the workbench, a hardness testing component fixedly connected to the top of the support columns, and support frames fixedly connected to both sides of the workbench". It has the technical effect of "the operator estimates that the new material to be tested has a high hardness and that the impact force of the fragments when it breaks is large. At this time, the operator connects the first glass cover, the second glass cover and the third glass cover to the movable frame. Then the operator starts the motor to rotate and drives the winding wheel to rotate, thereby winding the rope, so that the movable frame, the first glass cover, the second glass cover and the third glass cover all move upward, thereby protecting the operator. Since there are three layers of glass covers to protect the operator, the experimental risk of the operator is greatly reduced. The device has the advantage of easy adjustment of the number of protective baffle layers". In existing new material research and development test benches, the lids are usually opened and closed using simple hinges or direct sliding. When the lid is closed, the edge of the lid will directly rub and collide with the opening of the test chamber. This friction and collision will inevitably wear down the sealing surfaces of the opening and the lid, and long-term use will lead to seal failure. At the same time, the rough and forced closing also poses a risk of jamming, affecting the smoothness of operation and the reliability of the equipment. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an adjustable new material research and development test bench. Through control components, it achieves smooth opening and closing of the lid and rear storage, which not only provides reliable safety protection for the experimental process, but also saves operating space to the maximum extent and improves the safety and convenience of the equipment.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: an adjustable new material research and development test bench, including a frame, on which a test bench mechanism is provided and used for protection during the test; The main components include a base mounted on top of the frame, a test chamber fixed to the top of the base, and a cover on the test chamber; The control assembly includes fixed plates on the left and right sides of the rear end of the base. A second cylinder is installed at the lower end of the fixed plate. A bearing is fixed at the output end above the second cylinder. A rotating shaft is rotatably installed between the left and right ends inside the bearing. A swing arm is fixed at the outer end of the rotating shaft. A pulley is rotatably installed on the outer wall of the end of the swing arm away from the rotating shaft. A bracket is fixed on the surface of the swing arm, and the other end of the bracket is fixed to the rear end of the upper surface of the box cover. A guide component is provided on the fixed plate to guide the opening and closing trajectory of the box cover.

[0005] Preferably, the guiding component includes a guide plate fixed to the outer end of the base, the guide plate having a longitudinal groove inside, and a transverse groove at the upper end of the guide plate being connected to the upper end of the longitudinal groove.

[0006] Preferably, the control assembly further includes a connecting shaft fixed between the inner ends of the two rotating shafts.

[0007] Preferably, the control component further includes a guide rail fixed to the surface of the fixed plate, a slider slidably mounted on the guide rail, and a bearing fixed to the surface of the slider.

[0008] Preferably, the main component further includes two slide blocks fixed at the left and right ends of the frame, with slide rods slidably installed inside the slide blocks and fixed to the bottom of the base, and a first cylinder installed inside the frame for driving the base to lift.

[0009] Preferably, the main component also includes a pressure detection device installed inside the test chamber, and a control panel is installed at the front end of the frame.

[0010] Beneficial effects This invention provides an adjustable experimental platform for new material research and development. Compared with existing technologies, it has the following advantages: 1. When the lid needs to be closed, the output end of the second cylinder drives the shaft seat to move upward. The shaft seat drives the rotating shaft to rise synchronously, thereby forcing the swing arm, which is fixed to the rotating shaft, to move upward as a whole. During this process, the pulley at one end of the swing arm is constrained by the guide plate and first slides upward inside the longitudinal groove. At the same time, the swing arm drives the lid to be lifted vertically through the bracket. After the pulley runs to the top of the longitudinal groove and enters the transverse groove connected to it, the continuous thrust of the second cylinder will be converted into the power to force the swing arm to rotate forward around the axis of the rotating shaft. At this time, the pulley slides horizontally in the transverse groove, thereby driving the lid to tilt forward and downward through the bracket, and finally covering the top of the test chamber to form a shield, which can provide protection when the material breaks or reacts and splashes.

[0011] 2. The opened lid is completely retracted at the rear of the test chamber, maximizing the saving of operating space above and in front of the equipment, providing convenience for researchers to observe, take and put in samples and operate other equipment; the base is driven to move by the output end of the first cylinder, and the slide rod constrains the interior of the slide to slide vertically through; ensuring that the entire base and the test chamber, lid and control components it supports can be raised and lowered smoothly in the vertical direction.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0015] Please see Figure 1 - Figure 4 This utility model provides a technical solution: an adjustable new material research and development test bench, including a frame 1, on which a test bench mechanism 2 is provided and used for protection during the test; The main component 21 includes a base 211 disposed above the frame 1, a test chamber 212 fixed on the top of the base 211, and a cover 213 disposed on the test chamber 212; The control component 22 includes a fixing plate 221 fixed on the left and right sides of the rear end of the base 211. A second cylinder 222 is installed at the lower end of the fixing plate 221. A bearing seat 223 is fixed at the output end of the second cylinder 222. A rotating shaft 224 is rotatably installed between the left and right ends inside the bearing seat 223. A swing arm 225 is fixed at the outer end of the rotating shaft 224. A pulley 226 is rotatably installed on the outer wall of the end of the swing arm 225 away from the rotating shaft 224. A bracket 227 is fixed on the surface of the swing arm 225, and the other end of the bracket 227 is fixed to the rear end of the upper surface of the box cover 213. A guide component 228 is provided on the fixing plate 221 and is used to guide the opening and closing trajectory of the box cover 213.

[0016] In this embodiment, when the closing operation is required, the output end of the second cylinder 222 drives the shaft seat 223 to move upward. The shaft seat 223 drives the rotating shaft 224 to rise synchronously, thereby forcing the swing arm 225, which is fixed to the rotating shaft 224, to move upward as a whole. During this process, the pulley 226 at one end of the swing arm 225 is constrained by the guide plate 2281 and first slides upward inside the longitudinal slide groove 2282. At the same time, the swing arm 225 drives the box cover 213 to be vertically lifted through the bracket 227. After the pulley 226 runs to the top of the longitudinal slide groove 2282 and enters the transverse slide groove 2283 connected to it, the continuous thrust of the second cylinder 222 will be converted into the power to force the swing arm 225 to rotate forward around the axis of the rotating shaft 224. At this time, the pulley 226 slides horizontally in the transverse slide groove 2283, thereby driving the box cover 213 to tilt forward and downward through the bracket 227, and finally covering the test chamber 212 to form a shield, which can provide protection when the material test is broken or the reaction splashes.

[0017] Specifically, the guide component 228 includes a guide plate 2281 fixed to the outer end of the base 211. The guide plate 2281 has a longitudinal groove 2282 inside, and a transverse groove 2283 is provided at the upper end of the guide plate 2281 and is connected to the upper end of the longitudinal groove 2282.

[0018] In this embodiment, similarly, when it is necessary to open the lid, the process is reversed, and the opened lid 213 is completely stored behind the test chamber 212, which saves the operating space above and in front of the equipment to the greatest extent, providing convenience for researchers to observe, take and put in samples and operate other equipment.

[0019] Specifically, the control assembly 22 also includes a connecting shaft 229 fixed between the inner ends of the two rotating shafts 224.

[0020] In this embodiment, the connecting shaft 229 ensures that the left and right rotating shafts 224 maintain completely consistent angular and linear displacements.

[0021] Specifically, the control component 22 also includes a guide rail 2210 fixed to the surface of the fixed plate 221, a slider 2211 slidably mounted on the guide rail 2210, and a bearing seat 223 fixed to the surface of the slider 2211.

[0022] In this embodiment, when the output end of the second cylinder 222 drives the shaft seat 223 to move up and down, the slider 2211 fixed to the shaft seat 223 is constrained to slide on the path of the guide rail 2210 to avoid shaking or deviation.

[0023] Specifically, the main component 21 also includes two slide blocks 214 fixed at the left and right ends of the frame 1. A slide rod 215 is slidably installed inside the slide block 214 and fixed to the bottom of the base 211. A first cylinder 216 is installed inside the frame 1 and is used to drive the base 211 to lift.

[0024] In this embodiment, the base 211 is driven to move by the output end of the first cylinder 216, and the slide rod 215 is used to constrain the slide block 214 to slide vertically through it; this ensures that the entire base 211 and the test chamber 212, the cover 213 and the control components 22 supported on it can be raised and lowered smoothly in the vertical direction.

[0025] Specifically, the main component 21 also includes a pressure testing device 217 installed inside the test chamber 212, and a control panel 218 is installed at the front end of the frame 1.

[0026] In this embodiment, after the box cover 213 is closed under the drive of the control component 22, the pressure detection device 217 can be started and operated through the control panel 218 to apply pressure to the new material sample placed in the box. At the same time, the pressure detection device 217 will monitor and feed back the mechanical response data of the sample during the pressure process in real time. These key data, such as pressure value and deformation, are also centrally displayed and recorded through the control panel 218.

[0027] The working principle and usage process of this utility model are as follows: First, the base 211 is moved by the output end of the first cylinder 216, and the slide rod 215 is used to constrain the slide block 214 to slide vertically through it; this ensures that the entire base 211 and the test chamber 212, the cover 213 and the control components 22 supported above it can be raised and lowered smoothly in the vertical direction to the most suitable working height. Then, the new material sample is placed into the test chamber 212, and the output end of the second cylinder 222 drives the bearing seat 223 to move upward. The bearing seat 223 drives the rotating shaft 224 to rise synchronously, thereby forcing the swing arm 225, which is fixed to the rotating shaft 224, to move upward as a whole. During this process, the pulley 226 at one end of the swing arm 225 is constrained by the guide plate 2281 and first slides upward inside the longitudinal groove 2282. At the same time, the swing arm 225 drives the chamber cover 213 to be vertically lifted through the bracket 227. After the pulley 226 runs to the top of the longitudinal slide groove 2282 and enters the transverse slide groove 2283 connected to it, the continuous thrust of the second cylinder 222 will be converted into the power to force the swing arm 225 to rotate forward around the axis of the rotating shaft 224. At this time, the pulley 226 slides horizontally in the transverse slide groove 2283, thereby driving the box cover 213 to tilt forward and downward through the bracket 227, and finally covering the test box 212 to form a shield, which can provide protection when the material test is broken or the reaction splashes. Finally, the pressure testing device 217 can be started and operated through the control panel 218 to apply pressure to the new material sample placed in the chamber. At the same time, the pressure testing device 217 will monitor and provide feedback on the mechanical response data of the sample during the compression process in real time. These key data, such as pressure value and deformation, are also centrally displayed and recorded through the control panel 218.
