Description

Technical Field

[0001] This utility model relates to the field of support tooling technology, and in particular to a support tooling for laser cutting that prevents scratches on sheet metal parts. Background Technology

[0002] Sheet metal parts are components made by cutting, stamping, bending, welding, and surface treatment of metal sheets. They are used in the fields of automobiles, electronic equipment, communication base stations, medical devices, and construction machinery. Their core characteristics are that they use sheet metal as the base material and achieve specific structures and functions through plastic deformation. They have the advantages of lightweight, high strength, and large-scale production. Therefore, in the laser cutting process, support fixtures are required to complete the process.

[0003] After cutting, the existing support fixtures tend to fit tightly against the sheet metal parts, making them difficult to remove and requiring manual disassembly. This can damage the cut sheet metal parts. The current solution is to install a cylinder or spring-loaded rod at the bottom of the support fixture. After cutting, the sheet metal parts are lifted off the support fixture by controlling the extension and retraction of the cylinder or spring, making them easier to remove. This solves the problem of inconvenient removal. However, when fixing the sheet metal parts, the clamping force of the fixing fixture is still too large, resulting in excessive concentration of clamping force. This causes the fixture to scratch the sheet metal parts, reducing product quality and affecting the processing effect. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a support fixture for laser cutting to prevent scratches on sheet metal parts. It aims to improve the problem in the prior art where excessive clamping force causes scratches on sheet metal parts, reducing product quality and affecting processing results.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a support fixture for laser cutting to prevent scratches on sheet metal parts, comprising a fixed frame, a stabilizing mechanism provided on the inner bottom wall of the fixed frame, a support plate fixedly connected to the left side of the top wall of the fixed frame, and a collecting mechanism provided on the inner top wall of the support plate.

[0006] The stabilizing mechanism includes a support shell, the bottom of which is fixedly connected to the inner bottom wall of the fixed frame. Support seats are fixedly connected to the front and rear sides of the top wall of the fixed frame. A swing cylinder is fixedly connected to the top of the support seat. A rotating shell is fixedly connected to the right end of the swing cylinder. A mounting plate is fixedly connected to one end of the rotating shell. Bolts are threaded to the left and right sides of the top wall of the mounting plate. Heat-resistant pads are threaded to the ends of the bolts. A locking assembly is provided at the front and rear ends of the right side of the fixed frame.

[0007] As a further description of the above technical solution:

[0008] The collection mechanism includes an extraction fan, the top of which is fixedly connected to the inner top wall of the support plate. A connecting pipe is connected to the front end of the extraction fan, and a collection box is connected to the right end of the connecting pipe. A filter plate is slidably connected to the inner wall of the collection box, and a pull-out assembly is provided on the top of the filter plate. A connecting frame is connected to the right side of the collection box, and the right side of the connecting frame is connected to the left side of the support shell. A guide plate is fixedly connected to the inside of the support shell, and multiple connecting slots are provided on the top wall of the support shell.

[0009] As a further description of the above technical solution:

[0010] The positioning assembly includes two positioning plates, the bottoms of which are fixedly connected to the front and rear ends of the top right side of the fixed frame, and the inner walls of the positioning plates are connected with rubber pads.

[0011] As a further description of the above technical solution:

[0012] The pull assembly includes two pull rods, the bottoms of which are fixedly connected to the front and rear sides of the top wall of the filter plate, respectively, and a rubber shell is fixedly connected to the middle of the pull rods.

[0013] As a further description of the above technical solution:

[0014] A control switch is fixedly connected to the left side of the support plate, and the control switch is electrically connected to the swing cylinder and the extraction fan respectively.

[0015] As a further description of the above technical solution:

[0016] A rubber ring is fixedly connected to the right end of the outer wall of the connecting pipe, and the outer wall of the rubber ring is fixedly connected to the left side of the collection box.

[0017] As a further description of the above technical solution:

[0018] The fixed frame is fixedly connected to two connecting seats on both the front and rear sides, and the top of the connecting seats is provided with mounting holes.

[0019] As a further description of the above technical solution:

[0020] The stabilizing mechanism also includes multiple rubber rings, the inner walls of which are respectively fixedly connected to the upper part of the outer wall of the bolt.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the heat-resistant pad can be disassembled and installed by rotating the bolt, thereby achieving flexible replacement. Then, driven by the swing cylinder, the rotating shell can drive the mounting plate to swing, so that the heat-resistant pad can press and fix the sheet metal parts. With the help of the locking component, the sheet metal parts can be limited and fixed. Thus, the heat-resistant pad can increase the fixing area with the sheet metal parts, thereby reducing the situation where the clamping force is too concentrated and the sheet metal parts are scratched.

In this utility model, by opening multiple connecting slots, the waste residue generated after laser cutting can enter the interior of the support shell, and then enter the connecting frame through the guide plate. Then, with the start of the extraction fan, the waste residue can be drawn into the collection box. Subsequently, the waste residue is uniformly collected and processed under the obstruction of the filter plate, avoiding the situation where the waste residue accumulates on the top of the support shell and affects subsequent cutting.

[0031] 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.

[0032] Reference Figure 1 , Figure 2 and Figure 4 An embodiment of this utility model is provided: a support fixture for laser cutting to prevent scratches on sheet metal parts, including a fixed frame 1, a stabilizing mechanism 2 is provided on the inner bottom wall of the fixed frame 1, the stabilizing mechanism 2 is used to reduce scratches that occur during sheet metal processing, a support plate 4 is fixedly connected to the left side of the top wall of the fixed frame 1, and a collecting mechanism 3 is provided on the inner top wall of the support plate 4.

[0033] The stabilizing mechanism 2 includes a support shell 201. The bottom of the support shell 201 is fixedly connected to the inner bottom wall of the fixed frame 1. Support seats 202 are fixedly connected to the front and rear sides of the top wall of the fixed frame 1, so that the swing cylinder 203 can be fixed under the connection of the support seats 202. The swing cylinder 203 is fixedly connected to the top of the support seat 202. The right end of the swing cylinder 203 is fixedly connected to a rotating shell 204. Then, driven by the swing cylinder 203, it can drive the rotating shell 204 to rotate. One end of the rotating shell 204... A mounting plate 205 is fixedly connected, and the mounting plate 205 swings synchronously, so that the heat-resistant pad 207 installed by bolts 206 can stably operate the sheet metal parts. Since the heat-resistant pad 207 has a large fixing area, it reduces the possibility of scratches on the sheet metal parts caused by excessive clamping force. Bolts 206 are threaded on both sides of the top wall of the mounting plate 205, and the ends of the bolts 206 are threaded to the heat-resistant pad 207, thus ensuring the processing quality. The front and rear ends of the right side of the fixed frame 1 are equipped with locking components 209.

[0034] Specifically, the bottom of the support shell 201 is fixedly connected to the inner bottom wall of the fixed frame 1, and the front and rear sides of the top wall of the fixed frame 1 are fixedly connected to the support bases 202. The swing cylinder 203 fixedly connected to the top is fixed through the connection of the support bases 202. The right end of the swing cylinder 203 is fixedly connected to the rotating shell 204. Under the drive of the swing cylinder 203, the rotating shell 204 is driven to rotate. The mounting plate 205 fixedly connected to one end of the rotating shell 204 swings synchronously. The left and right sides of the top wall of the mounting plate 205 are threadedly connected to bolts 206. The heat-resistant pad 207 threaded at the end of the bolts 206 swings with the mounting plate 205 to stabilize the sheet metal parts. Since the heat-resistant pad 207 has a large fixed area, it reduces the situation where the clamping force is too concentrated and the sheet metal parts are scratched, thereby ensuring the processing quality.

[0035] Reference Figure 1 , Figure 3 and Figure 5 The collection mechanism 3 includes an extraction fan 301, the top of which is fixedly connected to the inner top wall of the support plate 4. A connecting pipe 302 is connected to the front end of the extraction fan 301, and a collection box 303 is connected to the right end of the connecting pipe 302. This allows the airflow path to be connected through the connecting pipe 302 when the extraction fan 301 is activated, enabling the collection box 303 to collect the waste residue brought by the airflow extraction. A filter plate 304 is slidably connected to the inner wall of the collection box 303, ensuring uniform blocking and collection of the waste residue. The top of the filter plate 304 is provided with a pull-out component 308. The right side of the collection box 303 is connected to a connecting frame 305. The right side of the connecting frame 305 is connected to the left side of the support shell 201. The inside of the support shell 201 is fixedly connected with a guide plate 306. The guide plate 306 can guide the waste residue falling through the connecting groove 307 into the inside of the connecting frame 305, and then collect it by the extracted airflow. The top wall of the support shell 201 has multiple connecting grooves 307, which ultimately avoids the accumulation of waste residue from affecting subsequent cutting.

[0036] Specifically, the top of the extraction fan 301 is fixedly connected to the inner top wall of the support plate 4, and the right end of the connecting pipe 302 connected to the front end is connected to the collection box 303. When the extraction fan 301 is started, the airflow path is connected through the connecting pipe 302. The collection box 303 collects the waste residue brought by the airflow extraction. The filter plate 304 slidably connected to the inner wall of the collection box 303 completes the unified blocking and collection of waste residue. The top of the filter plate 304 is equipped with a pull component 308. The right side of the connecting frame 305 connected to the right side of the collection box 303 is connected to the left side of the support shell 201. The guide plate 306 fixedly connected inside the support shell 201 guides the waste residue falling through the multiple connecting slots 307 opened in the top wall, so that the waste residue enters the interior of the connecting frame 305 and is then carried into the collection box 303 by the extraction airflow, thus avoiding the accumulation of waste residue that affects subsequent cutting.

[0037] Reference Figure 1 , Figure 3 and Figure 4 The positioning assembly 209 includes two positioning plates 2091, the bottom of which is fixedly connected to the front and rear ends of the top right side of the fixed frame 1. Rubber pads 2092 are fixedly connected to the inner walls of the positioning plates 2091. Two connecting seats 6 are fixedly connected to the front and rear sides of the fixed frame 1. The top of the connecting seats 6 is provided with mounting holes 7. The stabilizing mechanism 2 also includes multiple rubber rings 208, the inner walls of which are fixedly connected to the upper middle part of the outer wall of the bolts 206.

[0038] Specifically, the connection between the locking plate 2091 and the rubber pad 2092 enables the locking operation on the right side of the sheet metal part. The connection between the connecting seat 6 and the mounting hole 7 enables the device to be fixedly installed. The rubber ring 208 reduces the rotational damage of the bolt 206 to the mounting plate 205.

[0039] Reference Figure 1 , Figure 4 and Figure 5 The pull assembly 308 includes two pull rods 3081, the bottoms of which are fixedly connected to the front and rear sides of the top wall of the filter plate 304, respectively, and a rubber shell 3082 is fixedly connected to the middle of the pull rods 3081; a control switch 5 is fixedly connected to the left side of the support plate 4, and the control switch 5 is electrically connected to the swing cylinder 203 and the extraction fan 301 respectively; a rubber ring 309 is fixedly connected to the right end of the outer wall of the connecting pipe 302, and the outer wall of the rubber ring 309 is fixedly connected to the left side of the collection box 303;

[0040] Specifically, the connection between the pull rod 3081 and the rubber shell 3082 improves the anti-slip effect of the pull rod 3081 when pulling out the filter plate 304. The control switch 5, which is electrically connected to the swing cylinder 203 and the extraction fan 301 respectively, enables the equipment to be turned on and off. The connection of the rubber ring 309 improves the protection effect at the bottom connection of the connecting pipe 302.

[0041] Working principle: At the beginning of use, the heat-resistant pad 207 can be disassembled and installed by rotating the bolt 206, which can be flexibly replaced and improves the flexibility of fixing and limiting. Then, when fixing begins, the swing cylinder 203 is activated, which drives the rotating shell 204 fixedly connected to the right end to rotate. The mounting plate 205 fixedly connected to one end of the rotating shell 204 swings synchronously, thereby driving the heat-resistant pad 207 to press and fix the sheet metal part. With the help of the clamping plate 2091, the sheet metal part is limited. At the same time, because the heat-resistant pad 207 has a large fixing area, it can reduce the possibility of scratching the sheet metal part due to excessive clamping force, ensuring processing quality and improving processing efficiency.

[0042] Furthermore, multiple connecting slots 307 are opened on the top wall of the support shell 201. The waste generated after laser cutting enters the interior of the support shell 201 through the connecting slots 307. The guide plate 306 fixedly connected inside the support shell 201 guides the waste into the connecting frame 305 connected on the left side of the support shell 201. The top of the extraction fan 301 is fixedly connected to the top wall of the support plate 4. After starting, the airflow path is connected through the connecting pipe 302 connected at the front end. The collection box 303 connected at the right end of the connecting pipe 302 draws the waste in the connecting frame 305 into the interior under the action of airflow. The filter plate 304 slidably connected to the inner wall of the collection box 303 blocks the waste and completes unified collection and treatment. The pull-out component 308 on the top of the filter plate 304 facilitates subsequent operations. Through the above process, the waste is prevented from accumulating on the top of the support shell 201 and affecting subsequent cutting.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
