Description

Technical Field

[0001] The utility model belongs to the field of bellows clamping devices, and in particular relates to an adjustable clamp for bellows processing. Background Art

[0002] Since the bellows are soft, foldable and retractable, they are widely used in chemical, electric power, civil engineering and other industries. Depending on the different places where the bellows are used, the produced bellows often need to be processed. In the process of processing the bellows, clamps are needed to fix the bellows.

[0003] At present, the existing clamps often fix the bellows by applying force from the outside to the inside. However, since the bellows has a special corrugated structure on the outside, the corrugated structure on the outside of the pipe is easily damaged by the clamps applying force from the outside.

[0004] Therefore, in order to address the problem that the existing clamp that applies force from the outside to the inside to fix the corrugated pipe is prone to damage to the corrugated structure when facing a corrugated pipe with a special pipe shape and a thin pipe wall, an adjustable corrugated pipe processing clamp is designed to apply force from the inside of the pipe to fix it instead of the traditional external clamping method, thereby avoiding applying force to the corrugated structure and preventing the corrugated structure from being damaged. Utility Model Content

[0005] In order to overcome the problem that the existing clamps that apply force from the outside to fix the corrugated pipes are prone to damage to the corrugated structure of the corrugated pipes when facing the corrugated pipes with special pipe shapes and thin pipe walls.

[0006] The technical solution of the utility model is: an adjustable fixture for processing bellows, including a supporting platform, a mounting plate, a clamping assembly, an inflation assembly, and a rotating assembly; the supporting platform is fixedly connected to the mounting plate, a clamping assembly for fixing the bellows is installed on one side of the mounting plate, the bellows is sleeved on the outside of the clamping assembly, an inflation assembly for adjusting the outer diameter of the clamping assembly is installed on the other side of the mounting plate, and a rotating assembly for adjusting the angle of the clamping assembly and the bellows is installed on the mounting plate.

[0007] Preferably, by changing the clamp from applying force from the outside to applying force from the inside, the contact between the clamp and the corrugated structure of the bellows is avoided, and damage to the corrugated structure is not caused. The outer diameter of the clamping assembly can be changed through the inflation assembly, and the limit ring can adjust the length of the changed outer diameter of the clamping assembly, thereby improving the versatility of the adjustable bellows processing clamp.

[0008] Preferably, the clamping assembly includes a support tube and a support sleeve; a hollow support tube is inserted into one side of the mounting plate, a support sleeve is sleeved on the support tube, and a bellows is sleeved on the support sleeve. The support tube can play a supporting role to prevent the support sleeve from bending and deforming due to a limit ring with a certain weight. The support sleeve is fixedly connected to the support tube, and the effect of adjusting the outer diameter of the clamping assembly is achieved by filling air to change the distance between the support sleeve and the support tube.

[0009] Preferably, the inflation component includes an air outlet hole and an air pump; two groups of air outlet holes are opened on the support tube and are opposite to each other on the left and right, an air pump is arranged on one side of the mounting plate, an air supply pipe connected to the air pump is inserted into the support tube, only the part of the support tube with the air outlet hole is a hollow structure, and the rest of the support tube is a solid structure, the air pump inputs the gas into the support tube through the air supply pipe, and the gas then flows out through the air outlet holes opened on the support tube to fill the distance between the support sleeve and the support tube.

[0010] Preferably, a valve is installed on the gas pipeline, a support plate is fixedly connected to one side of the mounting plate, and the air pump is installed on the support plate. The valve can control the flow rate of gas transported by the air pump. The support plate supports the air pump. The air pump is installed on the support plate so that there is a certain distance between the air pump and the mounting plate, which is convenient for opening or closing the valve.

[0011] Preferably, a limiting ring is provided on the outside of the support tube, and the limiting ring is slidably connected to the outside of the support sleeve, and the limiting ring is close to one side of the bellows. The limiting ring has a certain weight, so that it is close to the support sleeve, and has a pressing effect on the support sleeve, forming an obstacle, limiting the inflation range, and making the inflation range consistent with the length of the bellows, so as to avoid the situation where the gas fills the support sleeve in the front area without the bellows when the bellows is shorter, thereby causing waste of gas.

[0012] Preferably, the rotating assembly includes a No. 1 gear and a No. 2 gear; the No. 1 gear is sleeved on the outer side of the support tube, and the No. 2 gear meshing with the No. 1 gear is arranged above the No. 1 gear. The No. 2 gear is driven to rotate by rotating the No. 1 gear, thereby achieving the effect that the clamping assembly and the bellows fixed on the clamping assembly rotate together. When the side wall of the bellows is processed, the rotating assembly can be used to adjust the angle of the bellows.

[0013] Preferably, the rotating assembly includes a rotating shaft and a motor; one side of the No. 2 gear is fixedly connected to a rotating shaft movably connected to the mounting plate, and one side of the mounting plate is equipped with a transmission element connected to the motor on the rotating shaft. The motor drives the rotating shaft to rotate, and the No. 1 gear fixedly connected to the rotating shaft also rotates with the rotating shaft, thereby driving the meshing No. 2 gear to rotate.

[0014] Beneficial effects of the utility model:

[0015] 1. By improving the original clamp that never applies force from the outside to a clamp that applies force from the inside, the bellows is fixed by supporting the bellows wall from the inside of the bellows. The clamp that applies force from the inside does not directly contact the corrugated structure of the bellows and will not cause damage to the corrugated structure. At the same time, the internal clamping and fixing can also provide support from the inside of the hollow bellows to prevent the bellows from deformation during processing;

[0016] 2. Use an air pump to inflate the support sleeve to expand it to fit the inner wall of the bellows, and it can be adjusted accordingly according to the different diameters of the bellows;

[0017] 3. The limit block can suppress the support sleeve to form a barrier to prevent the gas in the air pump from entering the support sleeve whose length is shorter than the bellows, so that the inflation range of the support sleeve is adjusted accordingly according to the length of the bellows connected to the support sleeve, thereby reducing gas waste.

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0026] See also Figure 1-2The utility model provides an embodiment: an adjustable fixture for processing bellows includes a supporting platform 1, a mounting plate 2, a clamping assembly, an inflatable assembly, and a rotating assembly; the supporting platform 1 is fixedly connected to a mounting plate 2, a clamping assembly for fixing the bellows is installed on one side of the mounting plate 2, the bellows is sleeved on the outside of the clamping assembly, an inflatable assembly for adjusting the outer diameter of the clamping assembly is installed on the other side of the mounting plate 2, and a rotating assembly for adjusting the angle of the clamping assembly and the bellows is installed on the mounting plate 2. By changing the fixture that applies force from the outside to applying force from the inside, the contact between the fixture and the corrugated structure of the bellows is avoided, and the damage to the corrugated structure is not caused. The outer diameter of the clamping assembly can be changed by the inflatable assembly, and the limit ring 6 can adjust the length of the changed outer diameter of the clamping assembly, thereby improving the versatility of the adjustable fixture for processing bellows.

[0027] See also Figure 2-4 In this embodiment, the clamping assembly includes a support tube 301 and a support sleeve 302; a hollow support tube 301 is plugged into one side of the mounting plate 2, a support sleeve 302 is sleeved on the support tube 301, and a bellows is sleeved on the support sleeve 302. The inflation assembly includes an air outlet 401 and an air pump 402; two groups of air outlets 401 opposite to each other are opened on the support tube 301, an air pump 402 is arranged on one side of the mounting plate 2, an air supply pipe connected to the air pump 402 is plugged into the support tube 301, a valve is installed on the air supply pipe, a support plate 5 is fixedly connected to one side of the mounting plate 2, and the air pump 402 is installed on the support plate 5. The support tube 301 can play a supporting role to prevent the limit ring 6 with a certain weight from causing the support sleeve 302 Bending and deforming, the support sleeve 302 is fixedly connected to the support tube 301, and the effect of adjusting the outer diameter of the clamping component is achieved by filling air to change the distance between the support sleeve 302 and the support tube 301. Only the part of the support tube 301 with the air outlet hole 401 is a hollow structure, and the rest of the parts are solid structures. The air pump 402 inputs the gas into the support tube 301 through the air supply pipe, and then flows out through the air outlet hole 401 opened on the support tube 301 to fill the distance between the support sleeve 302 and the support tube 301. The valve can control the flow rate of the gas transported by the air pump 402. The support plate 5 supports the air pump 402 and is installed on the support plate 5 so that the air pump 402 has a certain distance from the mounting plate 2, which is convenient for opening or closing the valve.

[0028] See also Figure 5-6In this embodiment, a limiting ring 6 is provided on the outside of the support tube 301, and the limiting ring 6 is slidably connected to the outside of the support sleeve 302, and the limiting ring 6 is close to one side of the corrugated tube. The rotating assembly includes a No. 1 gear 701 and a No. 2 gear 702; the No. 1 gear 701 is sleeved on the outside of the support tube 301, and a No. 2 gear 702 meshing with the No. 1 gear 701 is provided above the No. 1 gear 701, and the rotating assembly includes a rotating shaft 703 and a motor 704; one side of the No. 2 gear 702 is fixedly connected to a rotating shaft 703 movably connected to the mounting plate 2, and a transmission element is installed on one side of the mounting plate 2. The motor 704 connected to the rotating shaft 703, the limiting ring 6 has a certain weight, so that it is close to the support sleeve 302, which suppresses the support sleeve 302, forms an obstacle, limits the inflation range, and makes the inflation range consistent with the length of the bellows, so as to avoid the waste of gas when the bellows is shorter and the gas fills the support sleeve 302 in the front area without bellows. By rotating the No. 1 gear 701 to drive the No. 2 gear 702 to rotate, the clamping assembly and the bellows fixed on the clamping assembly can be rotated together. When the side wall of the bellows is processed, the rotating assembly can be used to adjust the angle of the bellows. The motor 704 drives the rotating shaft 703 to rotate, and the No. 1 gear 701 fixedly connected to the rotating shaft 703 also rotates with the rotating shaft 703, thereby driving the meshing No. 2 gear 702 to rotate.

[0029] When working, the staff first puts the bellows to be processed on the support sleeve 302, and then makes one end of it close to the No. 1 gear 701, and then puts the limit block on the support sleeve 302, pinches the support sleeve 302 to prevent the support sleeve 302 from moving, and at the same time moves the limit ring 6 with the other hand to the other end close to the bellows, opens the valve, and the air valve inputs the internal gas into the support pipe 301 through the gas pipeline, and flows into the support sleeve 302 through the air outlet 401 opened on the support pipe 301. The limit ring 6 suppresses the support sleeve 302, and the gas cannot continue to flow forward. The support sleeve 302 can only be propped up from the inside to fill the inside of the bellows, support and fix the bellows, and then process the bellows;

[0030] When the bellows needs to be rotated to adjust its angle, the motor 704 is started, and the motor 704 drives the rotating shaft 703 and the No. 1 gear 701 fixedly connected to the rotating shaft 703 to rotate, and the No. 1 gear 701 pushes the No. 2 gear 702 meshing with it to rotate, and the supporting tube 301 fixedly connected to the No. 2 gear 702 rotates together with the bellows to adjust the angle.

[0031] Through the above steps, the clamp that originally did not apply force from the outside is improved into a clamp that applies force from the inside, and the bellows is fixed by supporting the bellows wall from the inside of the bellows. The clamp that applies force from the inside does not directly contact the corrugated structure of the bellows and will not cause damage to the corrugated structure. At the same time, the internal clamping fixation can also provide support from the inside of the hollow bellows to avoid deformation of the bellows during processing, so as to solve the problem that the existing clamp that applies force from the outside is prone to damage to the corrugated structure of the bellows when facing bellows with special tube shapes and thin tube walls.

[0032] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
