Description

Technical Field

[0001] This utility model belongs to the field of concrete block technology, specifically relating to a device for trimming the edges and corners of autoclaved aerated concrete blocks. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks, also known as "aerated blocks," are a lightweight, porous new type of wall material made primarily from cement, lime, and sand, with the addition of a suitable amount of foaming agent. The mixture is stirred with water, poured, and then steamed to create a porous structure, which is then cured under high temperature and pressure. Its interior contains a large number of uniformly distributed closed micropores, giving it the core characteristics of being lightweight, providing thermal insulation, and sound insulation. It also possesses a certain strength, meeting the needs of non-load-bearing walls or partially load-bearing walls. Construction is convenient, as it can be sawed and planed. Because the raw materials can utilize industrial waste and the production process has low energy consumption, it also meets green building and environmental protection requirements. Therefore, it is widely used in the construction of interior and exterior walls of various buildings, including residential buildings, commercial buildings, and industrial plants.

[0003] Currently, autoclaved aerated concrete (AAC) blocks typically require grinding devices to polish and trim their edges during processing. However, existing trimming devices lack an effective structure for oblique movement grinding and cannot be flexibly adapted to the bevel trimming needs of concrete blocks of different sizes. They often can only process blocks of specific specifications, resulting in poor versatility. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The trimming component of this utility model, through the cooperation of the obliquely distributed limiting slide groove three with the hydraulic cylinder two and the push bar, can drive the grinding roller to move obliquely for grinding, which can accurately trim the beveled edges and corners of the blocks and meet the trimming needs of concrete blocks of different sizes.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figure 1-4This utility model provides a corner trimming device for autoclaved aerated concrete (AAC) blocks, including a support frame 1. A placement platform 2 is fixedly connected to the bottom of the support frame 1. A fixing component is installed inside the placement platform 2 to fix the concrete block. A hydraulic cylinder 3 is fixedly connected to the top of the support frame 1. A trimming component is installed at the telescopic end of the hydraulic cylinder 3. The trimming component includes a support platform 301 fixedly connected to the telescopic end of the hydraulic cylinder 3. Two obliquely distributed limiting grooves 302 are symmetrically arranged inside the support platform 301. Limiting sliders 303 are slidably connected inside each of the two limiting grooves 302. The two limiting sliders 303 move closer to each other as they slide inside the limiting grooves 302. A rotary motor 304 is fixedly installed on the top of the second limiting slider 303. A grinding roller 305 is rotatably connected to the bottom of the second limiting slider 303. The rotary motor 304 can drive the grinding roller 305 to grind the edges and corners of the concrete block. A pusher 306 is slidably engaged on the outer side of the second limiting slider 303. The pusher 306 can not only push the second limiting slider 303, but also drive the second limiting slider 303 to reset. A hydraulic cylinder 307 is connected to the outer side of the pusher 306. The hydraulic cylinder 307 is fixedly installed on the top of the support platform 301. One end of the two limiting slide grooves 302 are close to each other. The telescopic end of the hydraulic cylinder 307 is fixedly connected to the pusher 306. The transmission end of the rotary motor 304 is driven by the grinding roller 305.

[0022] Hydraulic cylinder 3 pushes the support platform 301 towards the block until the grinding roller 305 approaches the block's corner. Then, hydraulic cylinder 307 activates, its extension end driving the push bar 306 to move. The push bar 306 then pushes the limiting slider 303, which is slidably engaged with it, to slide within the limiting groove 302. Simultaneously, the rotary motor 304, fixedly mounted on the top of the limiting slider 303, starts, its transmission end driving the grinding roller 305, rotatably connected to the bottom, to rotate at high speed. As the limiting slider 303 slides obliquely, the high-speed rotating grinding roller 305 performs oblique grinding along the block's corner, thus achieving the trimming operation. The design of one end of each of the two limiting grooves 302 being close to each other ensures that the grinding roller 305 can precisely conform to the angle of inclination of the block's corner for trimming.

[0023] The trimming component of this utility model, through the cooperation of the obliquely distributed limiting slide groove 302 with the hydraulic cylinder 2 307 and the push bar 306, can drive the grinding roller 305 to move obliquely for grinding, which can accurately trim the beveled edges and corners of the blocks and meet the trimming needs of concrete blocks of different sizes. The rotary motor 304 drives the grinding roller 305 to rotate at high speed, ensuring the efficiency and quality of edge trimming and reducing the workload of manual trimming. At the same time, the sliding cooperation of the limiting slider 2 303 in the limiting slide groove 302 ensures the stability of the movement trajectory of the grinding roller 305, avoids trimming errors caused by grinding position deviation, and improves trimming accuracy.

[0024] Specifically, such as Figure 1 and Figure 3 As shown, the fixing assembly includes a transmission cavity 201 inside the placement platform 2. A stepper motor 202 is fixedly installed inside the transmission cavity 201. A gear 1 203 is fixedly connected to the transmission end of the stepper motor 202. A gear 2 204 is meshed with the upper part of the gear 1 203. The gear 2 204 is rotatably connected to the upper part inside the transmission cavity 201. A bidirectional lead screw 205 is fixedly connected inside the gear 2 204. Limiting grooves 206 are provided at both the front and rear ends of the placement platform 2. The two ends of the bidirectional lead screw 205 are provided with reverse threads and pass through the limiting grooves 206 at the front and rear ends respectively. Clamping blocks 207 are slidably connected inside the two limiting grooves 206. The clamping blocks 207 are threadedly connected to the bidirectional lead screw 205. A rubber pad 208 is fixedly connected to the opposite side of the two clamping blocks 207.

[0025] The stepper motor 202 starts, and its transmission end drives the first gear 203 to rotate. The first gear 203 then drives the second gear 204 to rotate in the upper part of the transmission cavity 201. Since the second gear 204 is fixedly connected to a bidirectional lead screw 205, the rotation of the second gear 204 will drive the bidirectional lead screw 205 to rotate synchronously. Since the two ends of the bidirectional lead screw 205 are provided with reverse threads, and the clamping block 207 slidably connected inside the second limiting slide groove 206 is threadedly connected to the bidirectional lead screw 205, when the bidirectional lead screw 205 rotates, the two clamping blocks 207 will move along the second limiting slide groove 206 towards each other until the rubber pad 208 fixedly connected to the opposite side of the clamping block 207 is tightly attached to the surface of the block, thereby firmly fixing the block on the placement platform 2.

[0026] This utility model, through the setting of the fixing component, enables the meshing transmission of gear 1 203 and gear 2 204 to drive the rotation of the bidirectional lead screw 205. The reverse thread design at both ends of the bidirectional lead screw 205 allows the two clamping blocks 207 to move synchronously towards the center, ensuring the centered positioning of the block on the placement platform 2 and avoiding inaccurate corner trimming due to block offset.

[0027] Specifically, such as Figure 2and Figure 3 As shown, the left and right sides of the placement platform 2 are provided with limit grooves 4, and the inside of the limit grooves 4 is connected to limit sliders 5. A helical spring 6 is fixedly connected between the limit sliders 5 and the limit grooves 4. The cross-section of the limit sliders 5 is "L" shaped, and a chamfer 7 is provided on the top of the opposite side. The cross-section of the clamping block 207 is "U" shaped.

[0028] When the concrete block is placed on top of the placement platform 2, it first contacts the limiting slider 5 and is initially positioned by the tension of the helical spring 6.

[0029] Working principle and usage process of this utility model:

[0030] When the staff operates the device, they first place the concrete block to be repaired on the top of the placement platform 2 at the bottom of the support frame 1. During the placement process, the block will first come into contact with the limiting slider 5 that is slidably connected in the limiting sliding groove 4 on the left and right sides of the placement platform 2. At this time, the spiral spring 6 that is fixedly connected between the limiting slider 5 and the limiting sliding groove 4 will generate tension to initially position the block.

[0031] After the initial positioning is completed, the stepper motor 202 is started, and its transmission end drives the gear 1 203 to rotate. The gear 1 203 and the gear 2 204 rotate in the upper part of the transmission cavity 201, driving the bidirectional lead screw 205 to rotate synchronously. Since the bidirectional lead screw 205 is threadedly connected to the clamping block 207, the clamping block 207 will slide along the limit slide groove 206 towards each other until the rubber pad 208 fixedly connected to the opposite side of the clamping block 207 is tightly attached to the surface of the block, and the block is firmly fixed on the placement platform 2.

[0032] After fixing, start the hydraulic cylinder 3 fixedly connected to the top of the support frame 1. Its telescopic end pushes the support platform 301 to move closer to the block until the grinding roller 305 rotatably connected to the bottom of the support platform 301 approaches the edge of the block. Then start the hydraulic cylinder 307 fixedly installed on the top of the support platform 301. Its telescopic end drives the push bar 306 to move. The push bar 306 pushes the limit slider 303, which is slidably engaged with it, to slide in the limit groove 302, which is symmetrically opened on the left and right and distributed obliquely inside the support platform 301. At the same time, start the rotary motor 304 fixedly installed on the top of the limit slider 303. Its transmission end drives the grinding roller 305 to rotate at high speed. As the limit slider 303 slides obliquely along the limit groove 302, the high-speed rotating grinding roller 305 performs oblique grinding along the edge of the block to achieve the edge trimming operation.

[0033] After the trimming is completed, hydraulic cylinder 2 307 drives push bar 306 to reset, which in turn drives limit slider 2 303 back to its initial position. Hydraulic cylinder 1 3 drives support platform 301 to rise away from the block. Stepper motor 202 rotates in the opposite direction, driving bidirectional lead screw 205 to rotate in the opposite direction, causing the two clamping blocks 207 to move away from each other along limit slide groove 206, releasing the block from its fixation. The worker can then take out the trimmed block, completing a complete corner trimming operation.
