Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically to a clamping device for processing welding parts. Background Technology

[0002] In the processing of welded parts, precise clamping and fixing of the parts is often required to ensure the quality and accuracy of the welding. Existing welding part clamping devices have many shortcomings. For example, some clamping devices have simple structures and can only clamp parts of specific shapes and sizes, resulting in poor versatility. In other cases, the clamping force of some clamping devices is difficult to control precisely. Clamping too tightly can easily damage the surface of the parts, while clamping too loosely can cause the parts to shift during welding, affecting the welding effect and reducing the efficiency of the welding process.

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of this utility model proposes a welding parts processing clamping device, including a clamping plate 1. The clamping plate 1 is placed on a transmission mechanism and cooperates with each other to form a clamp for clamping welding parts. An abutting rod 2 is inserted into an insertion hole 101 on the clamping plate 1. The abutting rod 2 includes a rod sleeve 201 and a sliding rod 202 that are slidably connected to each other. A soft abutting head 203 is fixedly connected to one end of the sliding rod 202 outside the rod sleeve 201, and a piston 2022 is placed at the other end. A support spring 205 is fitted on the sliding rod 202 inside the rod sleeve 201. An air nozzle 204 placed on the rod sleeve 201 is connected to an air pump 3 through an air pipe. The air pump 3 is communicatively connected to a controller 4.

[0024] In use, the welding parts are placed at the designated position on the workbench, and then the clamping plate 1 is driven to move toward the welding parts, so that the abutting rod 2 abuts against the surface of the welding parts. Then, the clamping plate 1 is continuously driven to approach the welding parts until the soft abutting head 203 at the end of one of the slide rods 202 abuts against the end of the sleeve 201. Then, the air pump 3 is turned on by the controller 4 to inflate each sleeve 201 with air. The air pressure drives the slide rod 202 to slide in the sleeve 201, so that the soft abutting head 203 at the end of each slide rod 202 abuts against the surface of the welding parts. Thus, the welding parts are stably clamped and fixed by the cooperation between multiple clamping plates 1.

[0025] During inflation, when the air pressure reaches the pressure value set by the pressure relief valve, the pressure relief valve opens to release air, preventing excessive air pressure from affecting the stable use of the contact rod 2. At the same time, after the processing of the welded parts is completed, the drive clamp 1 is separated from the welded parts, so that the clamp 1 is reset. Then, through the cooperation of the solenoid valve and the pressure relief valve, the air that was previously pumped into the rod sleeve 201 by the air pump 3 is released, so that the slide rod 202 slides back to its original position under the action of the support spring 205, so that it can be used next time.

[0026] The clamping plate 1 is installed on the matching drive component. During use, the drive component moves the clamping plate 1, so that the clamping plate 1 clamps the welding accessory and fixes the welding accessory. The drive component of the fixture is a current technology, so it will not be described in detail and is not shown in the attached drawings.

[0027] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the sleeve 201 and the air nozzle 204 threaded to its end are both inserted into the insertion hole 101 on the clamping plate 1, which facilitates the stable installation of the abutting rod 2 onto the clamping plate 1, enabling stable cooperation between the two. Multiple evenly distributed abutting rods are formed on the clamping plate 1, so that when the clamping plate 1 clamps and fixes the welding parts, the sliding rod 202 of each abutting rod 2 abuts against the surface of the welding parts, providing stable and effective clamping and fixing. The abutting rods 2 vary with the surface shape of the welding parts. Different deformations are generated to improve the contact efficiency between the entire fixture and the welding parts, so as to achieve stable clamping and fixing. The fixture formed by the cooperation of the clamping plate 1 and the abutting rod 2 can adapt to the clamping and fixing operation of welding parts of various shapes. One end of the rod sleeve 201 is provided with a through hole 2011 for inserting the sliding rod 202, so that the sliding rod 202 can slide smoothly on the rod sleeve 201. The other end of the rod sleeve 201 is provided with a threaded connection section for connecting the air nozzle 204, so that the air nozzle 204 can be stably installed on the rod sleeve 201, so that they can be stably used together.

[0028] One end of the slide rod 202 extends through the through hole 2011 to the outside and is fixedly inserted into the socket provided on the soft contact head 203. This ensures that the slide rod 202 can slide smoothly on the sleeve 201, while the soft contact head 203 is stably installed at the end of the slide rod 202, so that the slide rod 202 and the welded parts form a soft contact, reducing wear on the surface of the welded parts and ensuring stable use. At the same time, under the action of abutment, the soft contact head 203 will produce appropriate deformation, increasing the contact area with the welded parts, thereby improving the direct contact efficiency between the two, so that the slide rod 202 can effectively contact the welded parts. The welding components are stably and effectively clamped and fixed. A mounting seat 2021 is fixedly connected to the end of the slide rod 202 located inside the sleeve 201. The piston 2022 is fixedly connected to the mounting seat 2021 and slides against the inner wall of the sleeve 201, which facilitates the stable installation of the piston 2022 on the slide rod 202. This allows the slide rod 202 and the sleeve 201 to cooperate to form a structure similar to a syringe. When air is filled into the sleeve 201, the air pressure can be used to drive the slide rod 202 to slide inside the sleeve 201, thereby achieving effective driving operation of the slide rod 202.

[0029] The connector 2042 integrally set on the air nozzle 204 is threadedly connected to the threaded connection section at the end of the rod sleeve 201. A sealing ring is placed between the connector 2042 and the rod sleeve 201 to facilitate the stable installation of the air nozzle 204 onto the rod sleeve 201, thereby sealing the end of the rod sleeve 201. The air nozzle 204 can be used to inflate or deflate the wall inside the rod sleeve 201. The quick-connect plug 2041 integrally set on the air nozzle 204 communicates with the internal cavity of the rod sleeve 201 and extends from one end of the insertion hole 101 to the outside of the clamping plate 1, so as to facilitate the stable connection of the air inlet or outlet pipe to the air nozzle 204, thus ensuring stable use.

[0030] One end of the support spring 205 abuts against the mounting base 2021, and the other end abuts against the inner wall of the through hole 2011 on the sleeve 201. This facilitates the stable installation of the support spring 205 at the overlapping part between the slide rod 202 and the sleeve 201, providing stable and effective support for the slide rod 202. During the sliding of the slide rod 202, the support spring 205 will also undergo appropriate deformation. After the internal air pressure of the sleeve 201 is restored to equilibrium, the support spring 205 will drive the slide rod 202 to slide within the sleeve 201, causing the slide rod 201 to return to its original position, thus facilitating stable use.

[0031] like Figure 1 As shown, in some embodiments, a solenoid valve is installed on the air pipe connecting the air pump 3 and the air nozzle 204 at the end of the sleeve 201. A pressure relief valve is connected to the solenoid valve, facilitating the connection between the air pump 3 and the air nozzles 204 of each contacting rod 2. This allows the air pump 3 to pump air into the sleeve 201 of each contacting rod 2 through the air pipe during operation. The air pressure drives the slide rod 202 to slide within the sleeve 201, causing the slide rod 202, along with its end-mounted soft contact head 203, to move and abut against the clamped welding fitting, thereby causing the clamping plate 1... The solenoid valve and the pressure relief valve work together to securely clamp and fix the welding parts, facilitating subsequent processing. After processing of the clamped welding parts, the solenoid valve and the pressure relief valve work together to discharge the air in each sleeve 201, causing the pressure on the contact rod 2 to be released. As a result, the slide rod 202 slides back to its original position within the sleeve 201, releasing the clamping and fixing of the welding parts. The solenoid valve, the pressure relief valve, and the air pump 3 are connected in communication with the controller 4, facilitating flexible control of the solenoid valve, the pressure relief valve, and the air pump 3, thereby realizing the inflation and deflation operations of the contact rod 2.

Although the 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.
