Description

Technical Field

[0001] The utility model relates to the field of bellows processing, in particular to a bellows processing positioning and clamping device. Background Art

[0002] Bellows is a tubular elastic sensitive element, which is made of foldable corrugated sheets connected along the folding and stretching direction. Bellows are widely used in instruments and meters. The main purpose is to be used as a measuring element of pressure measuring instruments to convert pressure into displacement or force. The bellows wall is thinner and the sensitivity is higher. The measuring range is from tens of Pa to tens of MPa. Its open end is fixed, the sealed end is in a free state, and an auxiliary spiral spring or reed is used to increase the elasticity. When working, it stretches along the length of the tube under the action of internal pressure, so that the movable end produces a displacement that is related to the pressure. The movable end drives the pointer to directly indicate the size of the pressure. The bellows is often combined with a displacement sensor to form a pressure sensor with an output of electrical quantity, and is sometimes used as an isolation element. Since the extension of the bellows requires a large volume change, its response speed is lower than that of the Bourdon tube. The bellows is suitable for measuring low pressure. When cutting the bellows, a positioning clamping device is often required to clamp and fix it.

[0003] According to the Chinese patent with publication number: CN220971534U, a bellows processing positioning clamping device is provided, which includes a base, a movable groove is opened on the top surface of the base, a clamping assembly is arranged in the movable groove, the clamping assembly includes a fixed seat arranged on both sides of the movable groove, a positive and negative screw rod is rotatably connected between the fixed seats, symmetrical sliding rods are arranged on both sides of the positive and negative screw rods, one end of the positive and negative screw rods extends to the outside of the movable groove, the extended ends of the positive and negative screw rods are connected to a servo motor through a coupling, a first movable block and a second movable block are matched and connected to the outside of the positive and negative screw rods, both sides of the first movable block and the second movable block are slidably matched with the sliding rod, the tops of the first movable block and the second movable block are extended to the outside of the movable groove, the tops of the extended ends of the first movable block and the second movable block are fixedly connected with connecting blocks, the tops of the connecting blocks are opened with U-shaped grooves, a bellows is placed between the U-shaped grooves, and symmetrical limiting assemblies are arranged on both sides of the U-shaped grooves.

[0004] In the above scheme, the tops of the first movable block and the second movable block are extended to the outside of the movable groove, and the tops of the extended ends of the first movable block and the second movable block are fixedly connected to connecting blocks, and the tops of the connecting blocks are opened with U-shaped grooves, and bellows are placed between the U-shaped grooves. Symmetrical limit components are arranged on both sides of the U-shaped grooves, resulting in the following disadvantages: the existing bellows processing positioning and clamping devices usually need to use clamps to fix the bellows during the processing process, and the above-mentioned positioning and clamping devices are generally fixed manually using clamps, which is inefficient, and the above-mentioned comparative documents only clamp and fix the side walls of the bellows, and do not set up clamping structures for the bellows in different directions, which may cause the bellows to shift during the processing process, have poor stability, are not conducive to the processing of the bellows, and reduce the processing quality of the product. In order to increase the clamping effect of the bellows, clamping structures in different directions are adopted to avoid the need for manual clamping by personnel. We propose a bellows processing positioning and clamping device. Utility Model Content
