Description

Technical Field

[0001] This utility model belongs to the field of materials science and technology, and in particular relates to a separation device for testing samples after cutting composite materials. Background Technology

[0002] Separation devices for test samples after composite material cutting are typically used to ensure that the cut samples can be effectively separated, processed, and subsequently tested when cutting composite materials. After the composite material sample is cut, the separation device can automatically extract the sample from the cutting area or the table surface.

[0003] Existing separation devices for composite material test samples after cutting require contact with the material sample to collect the material after cutting, which poses certain safety risks when handling sharp or dangerous cut materials. Therefore, we propose a separation device for composite material test samples after cutting. Utility Model Content

[0004] The purpose of this invention is to provide a separation device for testing samples after cutting composite materials. By moving the contact plate downward, the actuating plate rotates within the moving plate. Then, when the contact plate returns to the stage, it drives the inclined push plate to move through the moving plate, thereby pushing the material with the inclined push plate. This solves the problem of automatically separating the cut material.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] Furthermore, the cutting machine is equipped with a replaceable saw blade, the contact plate is Z-shaped, the upper half of the inclined push plate is inclined, the moving plate is L-shaped, and there are two connecting blocks. The outer surface of the second connecting block is fixedly connected to the outer surface of the moving plate, and the end of the first spring away from the first connecting block is fixedly connected to the outer surface of the slide rod. The inner side of the first spring is sleeved with the outer surface of the slide rod.

[0010] Furthermore, the fixing mechanism includes a fixing frame fixedly connected to the top of the base, a slider slidably connected to the inner wall of the fixing frame, a clamping plate fixedly connected to the top of the slider, a pull bar fixedly connected to the bottom of the slider, a connecting rod rotatably connected to the inner wall of the pull bar, a rotating shaft fixedly connected to the end of the connecting rod away from the pull bar, a sliding cylinder rotatably connected to the outer surface of the rotating shaft, a fixing rod slidably connected to the inner wall of the sliding cylinder, a straight groove slidably connected to the outer surface of the rotating shaft, a moving plate fixedly connected to the bottom of the straight groove, a fixing frame slidably connected to the outer surface of the moving plate, a bolt threadedly connected to the inner wall of the fixing frame, and a positioning component provided at the top of the collecting frame.

[0011] Furthermore, the positioning component includes a baffle fixedly connected to the top of the collection frame, a connecting frame fixedly connected to the inner wall of the baffle, a limiting plate slidably connected to the inner wall of the connecting frame, a positioning plate fixedly connected to the side of the limiting plates that are close to each other, a limiting rod slidably connected to the inner wall of the limiting plate, a second spring fixedly connected to the side of the limiting plate that is away from the positioning plate, and a second bolt threadedly connected to the inner wall of the connecting frame, the outer surface of the second bolt contacting the outer surface of the limiting plate.

[0012] Furthermore, the inner wall of the positioning plate is provided with ball bearings, the inside of the fixing rod is provided with a groove that matches the outer surface of the slide cylinder, the slider is cross-shaped, the outer surface of the slide cylinder is fixedly connected with a handle, a total of several sliders are provided, the outer surface of the fixing rod is fixedly connected to the outer surface of the base, and the bottom of the fixing frame is fixedly connected to the outer surface of the base.

The inner side of the spring two is sleeved with the outer surface of the limiting rod.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model incorporates a contact plate that causes the servo motor to rotate in the opposite direction. The contact plate then moves upwards. When the contact plate touches the actuating plate again, the upper limit of the moving plate causes the contact plate to lift the moving plate upwards via the actuating plate. This, in turn, causes the inclined push plate to lift within the limit frame. The lifting of the contact plate allows the moving plate to move the inclined push plate, thus automatically separating the cut material. This reduces contact between the operator and the cutting tool, especially when handling sharp or dangerous materials, thereby mitigating potential safety risks.

[0016] 2. This utility model incorporates a clamping plate. By pulling the slide cylinder downwards using the handle, the slide cylinder moves downwards along the fixed rod, then pulls the connecting rod, which in turn pulls the pulling strips. Due to the action of the slider, the pulling strips move closer to each other, thereby causing the clamping plate to move and clamp the material. By using clamping plates that can move closer to each other, the material can be clamped and fixed during cutting, ensuring that the material does not shift or deform during the cutting process and avoiding inaccurate cutting caused by material shaking or sliding.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-10 As shown, this utility model is a separation device for testing samples after cutting composite materials. It includes a base 101, a support frame 102 fixedly connected to the top of the base 101, a separation mechanism 2 provided on the support frame 102, and a fixing mechanism 3 provided on the base 101. This device can cut the material through the separation mechanism 2 and automatically separate the material after cutting. Then, the fixing mechanism 3 can be used to position and fix the material before cutting.

[0033] The separation mechanism 2 includes a motor frame 201 fixedly connected to the top of the support frame 102. A servo motor 202 is fixedly connected to the inner wall of the motor frame 201. A threaded rod 203 is fixedly connected to the output shaft of the servo motor 202 through a coupling. A moving block 204 is threadedly connected to the outer surface of the threaded rod 203. The motor frame 201 fixes the servo motor 202 to prevent the servo motor 202 from rotating due to the rotation of the threaded rod 203, ensuring that the device can transmit normally. A moving strip 205 is fixedly connected to the side of the moving block 204 away from the servo motor 202. A driven strip 206 is fixedly connected to the side of the moving strip 205 away from the moving block 204. A cutting machine 207 is fixedly connected to the inner wall of the driven strip 206. A contact plate 208 is fixedly connected to the side of the driven strip 206 away from the moving strip 205. When the moving block 204 moves downward, it will drive the driven strip 206 to move downward through the moving strip 205, thereby causing the cutting machine 207 to move downward to cut the material.

[0034] A limiting frame 209 is fixedly connected to the outer surface of the base 101. There are two limiting frames 209. An inclined push plate 210 is slidably connected to the inner wall of the limiting frame 209. A moving plate 211 is fixedly connected to the side of the inclined push plate 210 away from the servo motor 202. The limiting frame 209 restricts the movement trajectory of the inclined push plate 210, so that the inclined push plate 210 can only move along a preset track, preventing the inclined push plate 210 from deviating during movement. A toggle plate 212 is slidably connected to the inner wall of the moving plate 211. A collection frame 218 is fixedly connected to the top of the base 101. A spring-loaded component is provided on the outer surface of the toggle plate 212. When the contact plate 208 returns to the stage, it can drive the moving plate 211 back to the stage through the toggle plate 212, thereby causing the inclined push plate 210 to move upward.

[0035] The rebound assembly includes a connecting block 213 fixedly connected to the outer surface of the actuating plate 212. A slide rod 214 is rotatably connected to the inner wall of the connecting block 213. A limit cylinder 215 is slidably connected to the outer surface of the slide rod 214. A connecting block 216 is rotatably connected to the end of the limit cylinder 215 away from the slide rod 214. A spring 217 is fixedly connected to the inner wall of the limit cylinder 215. The rebound of the spring 217 will reset the slide rod 214, thereby causing the slide rod 214 to drive the actuating plate 212 to reset through the connecting block 213, so that the contact plate 208 can contact the actuating plate 212 when it is lifted back.

[0036] The cutting machine 207 is equipped with a replaceable saw blade. The contact plate 208 is Z-shaped, the upper part of the inclined push plate 210 is inclined, the moving plate 211 is L-shaped, and there are two connecting blocks 213. The replaceable saw blade in the cutting machine 207 facilitates the maintenance of the device and ensures that the device can stably cut materials. The outer surface of the connecting block 216 is fixedly connected to the outer surface of the moving plate 211. The end of the spring 217 away from the connecting block 213 is fixedly connected to the outer surface of the slide rod 214. The inner side of the spring 217 is sleeved with the outer surface of the slide rod 214. The slide rod 214 restricts the movement trajectory of the spring 217 to prevent the spring 217 from tilting or deviating during movement, and ensures that the actuating plate 212 can be reset normally.

[0037] The fixing mechanism 3 includes a fixing frame 301 fixedly connected to the top of the base 101. A slider 302 is slidably connected to the inner wall of the fixing frame 301. A clamping plate 303 is fixedly connected to the top of the slider 302. A pull bar 304 is fixedly connected to the bottom of the slider 302. The slider 302 restricts the movement of the pull bar 304, so that the pull bar 304 can only move closer to each other, preventing the pull bar 304 from deviating during movement. A connecting rod 305 is rotatably connected to the inner wall of the pull bar 304. A rotating shaft 307 is fixedly connected to the end of the connecting rod 305 away from the pull bar 304. A slide cylinder 306 is rotatably connected to the outer surface of the rotating shaft 307. A fixing rod 308 is slidably connected to the inner wall of the slide cylinder 306. A groove provided on the fixing rod 308 limits the slide cylinder 306, preventing the slide cylinder 306 from rotating on the fixing rod 308, ensuring that the device can perform normal transmission.

[0038] A straight groove 309 is slidably connected to the outer surface of the rotating shaft 307. A moving plate 310 is fixedly connected to the bottom of the straight groove 309. A fixed frame 311 is slidably connected to the outer surface of the moving plate 310. A bolt 312 is threadedly connected to the inner wall of the fixed frame 311. A positioning component is provided at the top of the collection frame 218. After the material is pushed by the inclined push plate 210, the material will fall into the collection frame 218, which facilitates the collection of the cut material.

[0039] The positioning assembly includes a baffle 313 fixedly connected to the top of the collection frame 218. A connecting frame 314 is fixedly connected to the inner wall of the baffle 313. A limit plate 315 is slidably connected to the inner wall of the connecting frame 314. A positioning plate 316 is fixedly connected to the side of the limit plates 315 that is close to each other. The baffle 313 acts as a barrier to prevent the material from falling out of the device during cutting, thus protecting the workers. A limit rod 317 is slidably connected to the inner wall of the limit plate 315. A spring 318 is fixedly connected to the side of the limit plate 315 away from the positioning plate 316. A bolt 319 is threadedly connected to the inner wall of the connecting frame 314. The outer surface of the bolt 319 contacts the outer surface of the limit plate 315, allowing the bolt 319 to be tightened inside the connecting frame 314. At this time, the bolt 319 will contact the limit plate 315, thereby fixing the limit plate 315.

[0040] The inner wall of the positioning plate 316 is provided with ball bearings, and the inside of the fixing rod 308 is provided with a groove that matches the outer surface of the slide cylinder 306. The slider 302 is cross-shaped, and a handle is fixedly connected to the outer surface of the slide cylinder 306. The ball bearings on the positioning plate 316 will rotate when the inclined push plate 210 pushes the material, so that the inclined push plate 210 can push the material into the collection frame 218 for collection. Several sliders 302 are provided. The outer surface of the fixing rod 308 is fixedly connected to the outer surface of the base 101, and the bottom of the fixing frame 311 is fixedly connected to the outer surface of the base 101. The base 101 fixes the fixing rod 308 to prevent the fixing rod 308 from shifting due to the movement of the slide cylinder 306, so as to ensure that the device can perform normal transmission.

[0041] Bolt 312 has its outer surface in contact with the outer surface of the moving plate 310. There are two connecting frames 314, several limiting plates 315, and several limiting rods 317. Bolt 312 can be tightened inside the fixing frame 311. At this time, bolt 312 will contact the moving plate 310, thereby fixing the moving plate 310. The end of the limiting rod 317 away from the limiting plate 315 is fixedly connected to the inner wall of the connecting frame 314. The end of the spring 318 away from the limiting plate 315 is fixedly connected to the inner wall of the connecting frame 314. The inner side of the spring 318 is sleeved with the outer surface of the limiting rod 317. The limiting rod 317 restricts the movement trajectory of the spring 318 to prevent the spring 318 from tilting or deviating during movement, ensuring that the positioning plate 316 can properly position the material.

[0042] One specific application of this embodiment is:

[0043] When the staff needs to use the equipment, first place the material to be cut on the fixed frame 301, and then pull the slide cylinder 306 down through the handle. At this time, the slide cylinder 306 will move down along the fixed rod 308, and then the slide cylinder 306 will pull the connecting rod 305. At this time, the connecting rod 305 will pull the pulling bar 304. Due to the action of the slider 302, the pulling bars 304 will move closer to each other, so that the pulling bars 304 will drive the clamping plate 303 to move through the slider 302 to clamp the material. While the slide cylinder 306 is moving, it will also drive the rotating shaft 307 to move downward.

[0044] Then, the rotating shaft 307 drives the moving plate 310 to move downward through the straight groove 309. After the clamping plate 303 clamps the material, the bolt 312 is tightened in the fixed frame 311 to fix the moving plate 310. This achieves the effect of clamping and fixing the material during cutting, ensuring that the material will not be displaced or deformed during the cutting process, and avoiding inaccurate cutting caused by material shaking or sliding. At this time, the other end of the material will push the positioning plate 316, causing the positioning plate 316 to move away from each other. Then, the positioning plate 316 will squeeze the spring 318 through the limiting plate 315.

[0045] Then, the rebound of spring 2 318 will push the positioning plate 316 through the limiting plate 315, thereby clamping the material. Then, bolt 2 319 will be tightened in the connecting frame 314 to fix the limiting plate 315. Then, the servo motor 202 and the cutting machine 207 can be started. At this time, the cutting machine 207 will make the saw blade rotate at high speed to facilitate cutting the material. Then, the servo motor 202 will make the threaded rod 203 rotate. At this time, the rotation of the threaded rod 203 will make the moving block 204 move downward. Then, the moving block 204 will drive the moving strip 205 to move downward. After that, the moving strip 205 will drive the cutting machine 207 to move downward through the driven strip 206 to cut the material.

[0046] At this time, the driven bar 206 will also drive the contact plate 208 to move downward. When the contact plate 208 touches the actuating plate 212, it will press down one end of the actuating plate 212 near the inclined push plate 210. At this time, the other end of the actuating plate 212 will drive the connecting block 1 213 to tilt upward. Then the connecting block 1 213 will drive the slide bar 214 to tilt upward. After that, the slide bar 214 will slide in the limiting cylinder 215. At the same time, the slide bar 214 will also squeeze the spring 1 217. At the same time, the limiting cylinder 215 will also rotate at the connection between the limiting cylinder 215 and the connecting block 216. When the contact plate 208 is disengaged from the actuating plate 212, the spring 1 217 will rebound and reset the actuating plate 212.

[0047] After the cutting machine 207 finishes cutting the material, the servo motor 202 can be reversed. At this time, the contact plate 208 will move upward. When the contact plate 208 touches the actuating plate 212 again, due to the upper limit of the moving plate 211, the contact plate 208 will drive the moving plate 211 to rise upward through the actuating plate 212. At this time, the moving plate 211 will drive the inclined push plate 210 to rise within the limit frame 209. When the inclined push plate 210 touches the material, it will push the material into the collection frame 218 for collection. At this time, the ball bearings on the positioning plate 316 facilitate the inclined push plate 210 to push the material, achieving automatic separation of the cut material, reducing the contact between the operator and the cutting tool, especially when handling sharp or dangerous cutting materials, reducing potential safety risks.
