Description

Technical Field

[0001] The utility model relates to the technical field of metal product processing, and more specifically, to a clamp for metal product processing. Background Art

[0002] Metal products are various products made of metal materials. They have good electrical conductivity, thermal conductivity, plasticity and ductility. These properties make metal products widely used in various fields. Their diverse properties and forms make them an indispensable and important part of modern industry and life.

[0003] When current pipe fixtures are used to clamp round pipes with flanges, a through-hole needs to be drilled into the flange after assembly. This creates a gap between the flange and the traditional pipe fixture after clamping the pipe. During drilling, the vibrations applied by the drill bit to the flange cause the connecting flange and pipe to vibrate together, affecting the drilling effect. To address this issue, we propose a fixture for metal product processing. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, meet the actual needs, and provide a clamp for processing metal products to solve the technical problems that the current clamp has low stability when clamping pipes with flanges, is prone to vibration when drilling, and affects the drilling effect.

[0006] The connecting member includes a fixed block, and the upper and lower sides of the fixed block are fitted with adjustment plates. Bearings are fixed on the opposite sides of the two adjustment plates. The inner rings of the bearings are fixed with adjustment screws that pass through the adjustment plates. The side walls of the fixed block are provided with threaded holes that are engaged with the adjustment screws.

[0007] The clamping member includes three first curved plates and three second curved plates. The three first curved plates are detachably connected to the second curved plates at corresponding positions. The first curved plate in the middle is fixedly connected to the fixed block, and the first curved plates on the upper and lower sides are fixedly connected to the adjustment plate.

[0008] The utility model combines the three first curved plates with the fixed block and the adjustment plate on the connecting piece, and can adjust the positions of the first curved plates on the upper and lower sides under the control of the thread, thereby adjusting the distance between the two, so that the second curved plates connected to the first curved plates move synchronously, thereby clamping pipes of different lengths and keeping them in contact with the side faces of the flanges on the pipes. Such structural coordination can effectively improve the stability of pipe clamping, reduce the vibration force generated when drilling holes in the connecting flanges on the pipes, and improve the stability of drilling.

[0009] Preferably, the three first curved plates are provided with several groups of clips in a circular array on one side close to the second curved plates, and each group of clips is provided with two, and the three second curved plates are fixed with several connecting blocks combined with the clips on one side close to the first curved plates.

[0010] Preferably, arc-shaped slots are provided on opposite sides of a single group of clips, and arc-shaped clip strips combined with the arc-shaped slots are fixedly provided on the upper and lower side surfaces of the connecting block.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model combines the three first curved plates with the fixed block and the adjustment plate on the connecting piece, and can adjust the positions of the upper and lower first curved plates under thread control, thereby adjusting the distance between the two, so that the second curved plates connected to the first curved plates move synchronously, thereby clamping pipes of different lengths and keeping them in contact with the side faces of the flanges on the pipes. Such structural coordination can effectively improve the stability of pipe clamping, reduce the vibration force generated when drilling holes in the connecting flanges on the pipes, and improve the stability of drilling.

[0033] Working principle: This embodiment provides a clamp for processing metal products. When in use, the pipe fitting can be placed on the lifting platform 5 first, and then the first electric push rod 202 on the adjustment component 2 is operated to move the clamping members 4 on both sides to the outside of the pipe fitting, thereby clamping the pipe fitting. At the same time, the first curved plates 401 and the second curved plates 402 on the upper and lower sides of the clamping member 4 fit with the flange ring sides at both ends of the pipe fitting to play the role of clamping support. Then the pipe fitting can be opened. The support at both ends can keep it stable during the opening process. At the same time, after completing the opening control on one side, the pipe fitting can be flipped over to directly open the hole on the other side, eliminating the step of position adjustment. When the pipe fittings are clamped and limited, the adjusting screw 304 can be rotated to make the adjusting plate 302 drive the first curved plates 401 on both sides to move, and at the same time, the second curved plates 402 can be driven to move synchronously. In this way, the overall length can be adjusted to meet the needs of clamping and supporting pipe fittings of different lengths. Through such structural coordination, the use effect of clamping and limiting the pipe fittings can be improved. The first curved plate 401 and the second curved plate 402 are coordinated with the clamping piece 403 and the connecting block 404 for convenient disassembly and assembly operations. In this way, the second curved plate 402 of the corresponding size can be rotated according to pipe fittings of different sizes, thereby further improving the flexibility of the structural coordination and facilitating the processing and clamping needs of pipe fittings of different sizes.
