Description

Technical Field

[0001] The utility model relates to the technical field of bellows processing, in particular to a cutting device for welded bellows. Background Technique

[0002] A bellows refers to a tubular elastic sensitive element formed by connecting foldable corrugated sheets along the folding and telescoping direction. Bellows are widely used in instruments and meters. Their main use is as a measuring element in pressure measuring instruments to convert pressure into displacement or force. The bellows tube wall is relatively thin, with high sensitivity, and the measurement range is from dozens of pascals to dozens of megapascals.

[0003] During the processing and welding of bellows, cutting treatment is required. During the cutting process of bellows, most often an electric saw or laser cutting method is used. Such cutting methods mostly require manual transfer and then fixation, so as to complete the cutting of the bellows. However, such cutting methods are extremely likely to cause the bellows to move, resulting in inaccurate cutting positions of the bellows, and the degree of automation during the cutting process is low, affecting the processing efficiency. For this reason, we propose a cutting device for welded bellows. Content of the Utility Model

[0006] Furthermore, the pushing mechanism includes an electric slide rail, an electric slider, a first mounting plate, a first driving motor and a three-jaw chuck. Two groups of electric slide rails are fixedly installed on the top of the working plate, the electric slider is slidably connected to the electric slide rail, the top of the electric slider is fixedly installed with a first mounting plate, a first driving motor is fixedly installed on one side of the first mounting plate, and the output end of the first driving motor is fixedly connected with a three-jaw chuck.

[0007] Furthermore, the support mechanism includes a moving frame, a biaxial screw, a threaded sleeve, and a support wheel. A through groove is formed through the working plate. At the position corresponding to the through groove at the bottom of the working plate, a moving frame is fixedly installed. A biaxial screw is rotatably connected inside the moving frame. A second driving motor is fixedly installed on one side of the moving frame. The output end of the second driving motor is fixedly connected to the biaxial screw. Two groups of threaded sleeves are threadedly connected to the outer surface of the biaxial screw. The top of the threaded sleeve is rotatably connected to a support wheel through a connecting column.

[0008] Furthermore, the cutting mechanism includes a support frame, a driving cylinder, an installation box, and a laser cutting head. A support frame is fixedly installed on the working plate. A driving cylinder is fixedly installed on the top of the support frame. The output end of the driving cylinder is fixedly connected to an installation box.

[0009] Furthermore, the cutting mechanism further includes a fixing plate, a limiting wheel, and a positioning groove. Two groups of fixing plates are fixedly installed on both sides of the installation box.

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-4 , the present invention provides a technical solution: a welding bellows cutting device, including a working plate 1, the bottom of the working plate 1 is fixedly connected with support legs 2, the top of the working plate 1 is fixedly installed with a pushing mechanism 3 for driving the bellows to rotate and move, the working plate 1 is provided with a supporting mechanism 4 for limiting and supporting bellows of different sizes, and the top of the working plate 1 and on one side of the supporting mechanism 4 is fixedly installed with a cutting mechanism 5 for cutting the bellows.

[0019] Among them, by setting the pushing mechanism 3, the bellows can be driven to move and rotate towards the cutting mechanism 5, so that the cutting of the bellows can be completed by using the cutting mechanism 5. And during the cutting process, the cutting mechanism 5 has a certain limiting effect, which can prevent the bellows from shifting during the cutting process. And during the movement of the bellows, the supporting mechanism 4 can be used to limit and support the bellows to prevent the bellows from tilting due to the clamping and fixing on one side of the pushing mechanism 3. And the supporting position of the supporting mechanism 4 can be adjusted, so as to adapt to different bellows. Such a cutting method has a relatively high degree of automation and improves the cutting accuracy to a certain extent.

[0020] Please refer to Figure 1 and Figure 2 , the pushing mechanism 3 includes an electric slide rail 6, an electric slider 7, a first mounting plate 8, a first driving motor 9 and a three-jaw chuck 10. Two groups of electric slide rails 6 are fixedly installed on the top of the working plate 1. The electric slider 7 is slidably connected to the electric slide rail 6. The top of the electric slider 7 is fixedly installed with a first mounting plate 8. One side of the first mounting plate 8 is fixedly installed with a first driving motor 9. The output end of the first driving motor 9 is fixedly connected with a three-jaw chuck 10.

[0021] Among them, the corrugated pipe to be cut is fixed and clamped by a three-jaw chuck 10. Subsequently, the electric slider 7 can drive the first driving motor 9 and the three-jaw chuck 10 to move along the electric slide rail 6 towards the cutting mechanism 5. During the cutting process of the cutting mechanism 5, the first driving motor 9 drives the three-jaw chuck 10 and the corrugated pipe to rotate, so as to cooperate with the cutting mechanism 5 to cut the corrugated pipe.

[0022] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown in FIGS.

[0023] Among them, according to the size of the corrugated pipe to be cut, the second driving motor 17 is started to operate. The second driving motor 17 drives the double-shaft screw 13 to rotate, and the double-shaft screw 13 drives the thread sleeve 14, the connecting column 15 and the supporting wheel 16 to move relative to each other, so as to limit and support corrugated pipes of different sizes.

[0024] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown in FIGS.

[0025] Among them, after the corrugated pipe moves below the laser cutting head 21, the driving cylinder 19 drives the mounting box 20 and the laser cutting head 21 to move towards the cutting position. When the laser cutting head 21 moves, the positioning groove 24 between the two sets of limiting wheels 23 can fit with the convex position of the corrugated pipe, so that the corrugated pipe can be positioned during the cutting process. Subsequently, the laser cutting head 21 and the first driving motor 9 are used in cooperation to rotate and cut the corrugated pipe.

[0026] Please refer to Figure 1 , one side of the first mounting plate 8 is fixedly connected with a reinforcement plate 25 made of rigid material. The reinforcement plate 25 made of rigid material can prevent the first mounting plate 8 from tilting and deforming due to the heavy weight of the corrugated pipe clamped by the three-jaw chuck 10.

[0027] During use, first, the corrugated pipe to be cut is fixed and clamped by the three-jaw chuck 10. Subsequently, the electric slider 7 can drive the first driving motor 9 and the three-jaw chuck 10 to move along the electric slide rail 6 towards the cutting mechanism 5. When the cutting mechanism 5 is cutting, the first driving motor 9 drives the three-jaw chuck 10 and the corrugated pipe to rotate, so that it can cooperate with the cutting mechanism 5 to cut the corrugated pipe. According to the size of the corrugated pipe to be cut, the second driving motor 17 is started to operate. The second driving motor 17 drives the double-shaft screw 13 to rotate, and the double-shaft screw 13 drives the threaded sleeve 14, the connecting column 15 and the supporting wheel 16 to move relative to each other, so that the corrugated pipes of different sizes can be limited and supported. After the corrugated pipe moves below the laser cutting head 21, the driving cylinder 19 drives the mounting box 20 and the laser cutting head 21 to move towards the cutting position. When the laser cutting head 21 moves, the positioning groove 24 between the two sets of limiting wheels 23 can fit with the convex position of the corrugated pipe, so that the corrugated pipe can be positioned during the cutting process. Subsequently, the laser cutting head 21 and the first driving motor 9 are used in cooperation to rotate and cut the corrugated pipe.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
