Description

Technical Field

[0001] The utility model relates to the technical field of bellows processing, in particular to a fixing device used for bellows processing. Background Art

[0002] The bellows is a tubular elastic sensitive element, which is connected along the folding and stretching direction to form a cylindrical thin-walled corrugated shell with multiple transverse corrugations. It is usually elastic. During the processing of the bellows, a fixing device is usually used to clamp and fix the bellows to prevent the bellows from deflecting and affecting the processing.

[0003] When fixing the bellows, the existing fixing devices generally clamp the outer surface of the bellows. Since the outer surface of the bellows is in the shape of a transverse corrugation, the clamping parts on the fixing device will press the corrugated shape of the outer surface of the bellows during the clamping and fixing process. This clamping method will not only cause unnecessary pressure on the corrugations, causing the corrugations to deform or lose their original shape, affecting the performance of the bellows, such as flexibility, sealing and pressure resistance, but also at the crest of the corrugation, due to the clamping action of the fixing device, local stress concentration will occur, causing the corrugations of the bellows to fatigue, crack or break, thereby reducing the service life of the bellows.

[0004] Therefore, we proposed a fixing device for bellows processing to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] like Figure 1-4 As shown, a fixing device for processing corrugated pipes includes a workbench 1, the upper end surface of the workbench 1 is fixedly connected to a mounting frame 2, the upper end surface of the mounting frame 2 is fixedly connected to a cylinder 3, the output end of the cylinder 3 is fixedly connected to a lifting plate 4, the upper end surface of the workbench 1 and the lower end surface of the lifting plate 4 are both provided with sliding grooves 5, and arc-shaped clamping plates 6 are equidistantly slidably connected in the sliding grooves 5.

[0025] In this embodiment, Figure 3 As shown, a connecting plate 18 is provided between the upper arc-shaped clamping plate 6 and the lower arc-shaped clamping plate 6, and a vertical groove 19 is provided on the side of the connecting plate 18 close to the arc-shaped clamping plate 6. The lower arc-shaped clamping plates 6 are fixedly connected to the side walls of the connecting plates 18, and the upper arc-shaped clamping plates 6 are vertically slidably connected in the vertical groove 19. During the horizontal movement of the connecting plate 18, the arc-shaped clamping plate 6 can be synchronously driven to move through the vertical groove 19. When the upper arc-shaped clamping plate 6 is raised or lowered, it will slide along the vertical groove 19.

[0026] In this embodiment, Figure 1 and Figure 4As shown, a movable groove 7 is provided on the upper end surface of the workbench 1 near the connecting plate 18, and the lower end of the connecting plate 18 is slidably connected to the movable groove 7. The connecting plate 18 is fixedly connected to the side away from the arc-shaped clamping plate 6 with a connecting column 20, and a linkage plate 8 is arranged between the connecting columns 20. A limiting groove 17 is symmetrically provided on the side of the linkage plate 8 near the connecting column 20, and the connecting columns 20 are slidably connected to the limiting groove 17. The inclination angle of the limiting groove 17 from the center to the outside gradually increases. When the linkage plate 8 is lifted or lowered, the connecting column 20 is squeezed by the set limiting groove 17, so that the connecting plate 18 can be pushed to slide synchronously in the movable groove 7, and the same spacing is always maintained during the sliding process of the connecting plate 18.

[0027] In this embodiment, Figure 2 and Figure 3 As shown, a lifting block 10 is fixedly connected to the linkage plate 8 near the mounting frame 2. A through slot 9 is provided on the mounting frame 2. The lifting block 10 is vertically slidably connected in the through slot 9. When the lifting block 10 is driven to slide in the through slot 9, the linkage plate 8 can be driven to rise and fall synchronously.

[0028] In this embodiment, Figure 2 As shown, a sliding column 11 is slidably connected to the lifting block 10 on one side away from the linkage plate 8, and a handle 13 is fixedly connected to the end of the sliding column 11 away from the lifting block 10. A spring 12 is fixedly connected between the handle 13 and the lifting block 10, and the spring 12 is sleeved on the outer surface of the sliding column 11. When the handle 13 is pulled to drive the sliding column 11 to slide out from the inside of the lifting block 10, the spring 12 connected between the handle 13 and the lifting block 10 will be pulled at the same time. When the handle 13 is released, the rebound force of the spring 12 and the sliding column 11 cooperate with each other, and the handle 13 can be automatically pulled close to the lifting block 10.

[0029] In this embodiment, Figure 2 As shown, both sides of the handle 13 are fixedly connected to the limiting columns 14, and both sides of the handle 13 are provided with side panels 15, which are fixedly connected to the side walls of the mounting frame 2. The side panels 15 away from the mounting frame 2 are evenly spaced to form limiting holes 16, and the limiting columns 14 are engaged with the limiting holes 16. When the limiting columns 14 and the limiting holes 16 are engaged with each other, the handle 13 cannot slide up and down.

[0030] The effects achieved by this embodiment are as follows: In the prior art, the clamping piece on the fixing device will clamp at the crest of the corrugated pipe surface, which will not only cause unnecessary pressure on the corrugations, causing the corrugations to deform or lose their original shape, affecting the performance of the corrugated pipe, such as flexibility, sealing and pressure resistance, but also at the crest of the corrugations, due to the clamping effect of the fixing device, local stress concentration will occur, causing the corrugations of the corrugated pipe to fatigue, crack or break, thereby reducing the service life of the corrugated pipe. Compared with the prior art, in the process of clamping and fixing the corrugated pipe, the arc clamping plate 6 can be clamped in the depression between the crests of the corrugated pipe surface, which can not only better protect the corrugations on the surface of the corrugated pipe, avoid the corrugations from deforming or losing their original shape, thereby extending its service life, but also effectively prevent the corrugated pipe from slipping or shifting when subjected to external force, thereby enhancing the stability of the corrugated pipe during processing, and clamping at the trough, since the shape of the trough is relatively gentle, stress concentration can be reduced, thereby reducing the damage of the corrugated pipe due to excessive stress;

[0031] Secondly, through the limit groove 17 opened on the side wall of the linkage plate 8, the distance between the arc clamping plates 6 can be adjusted according to the gap between the corrugations of the corrugated pipe. Not only can the arc clamping plates 6 adapt to more types of corrugated pipes, improving the versatility and flexibility of the arc clamping plates 6, but the adjustable arc clamping plates 6 design makes the operation easier. The staff can quickly adjust the clamping position according to the actual situation, thereby improving work efficiency.

[0032] The working process and principle involved in the overall content of the above embodiment are as follows:

[0033] When the staff needs to fix the bellows, they first pull the handle 13 according to the gap of the corrugations on the surface of the bellows to drive the sliding column 11 to slide out of the lifting block 10, and simultaneously pull the spring 12 connected between the handle 13 and the lifting block 10. In the process of the handle 13 moving away from the lifting block 10, the limit columns 14 connected on both sides can be synchronously driven to slide out of the limit holes 16 opened on the side plates 15. After the limit columns 14 and the limit holes 16 are completely separated, the staff can press down the handle 13 to drive the lifting block 10 to synchronously descend in the through groove 9 through the sliding column 11. Since the lifting block 10 is connected to the linkage plate 8, as the lifting block 10 descends, the linkage plate 8 can be driven to move downward synchronously. At this time, during the descent of the linkage plate 8, the The height of the limiting groove 17 opened on the side wall of the linkage plate 8 enables the limiting groove 17 to apply pressure to the connecting column 20 slidably connected inside, pushing the connecting column 20 to slide in the limiting groove 17. Since the inclination angle of the limiting groove 17 from the center to the outside gradually increases, the sliding distance of the connecting column 20 will also increase one by one, so that the connecting columns 20 always maintain the same spacing. When the connecting column 20 slides along the path of the limiting groove 17, it can synchronously drive the connecting plate 18 to slide synchronously in the moving groove 7. At this time, the connecting plate 18 can drive the arc-shaped clamping plate 6 to slide synchronously in the sliding groove 5 through the vertical groove 19 opened on the side wall, thereby changing the spacing between the arc-shaped clamping plates 6, so that the arc-shaped clamping plates 6 can adapt to the gap between the corrugations on the surface of the corrugated pipe;

[0034] After the spacing between the arc-shaped clamping plates 6 is adjusted, the staff can release the handle 13. At this time, the handle 13 can be automatically pulled close to the lifting block 10 by the rebound force of the spring 12 connected between the handle 13 and the lifting block 10, driving the limit columns 14 connected on both sides of the handle 13 to slide into the limit holes 16 opened on the side plates 15, thereby fixing the spacing between the arc-shaped clamping plates 6 to prevent the position of the arc-shaped clamping plates 6 from changing during the clamping process of the corrugated pipe.

[0035] After the spacing between the arc-shaped clamping plates 6 is fixed, the staff can place the bellows on the arc-shaped clamping plate 6 below, and then open the cylinder 3 to push the lifting plate 4 down, driving the arc-shaped clamping plate 6 connected below the lifting plate 4 to slide downward synchronously along the vertical groove 19 opened on the side wall of the connecting plate 18, and descend to the gap between the corrugations on the surface of the bellows below, and clamp and fix the bellows, thereby avoiding damage to the corrugations on the surface of the bellows.
