Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical clamps, and more specifically, particularly relates to an adjustable clamp. Background Art

[0002] Shaft parts are generally cylindrical objects that transmit power. When producing shaft parts, it is necessary to first adjust the fixture to the appropriate position and then fix the shaft parts on the fixture to facilitate the processing and inspection of the shaft parts.

[0003] According to CN201511000755.2, the present invention discloses a special fixture for long shafts, including a support and a plurality of fasteners, a centrally placed V-shaped groove that runs through the top of the support, two guide grooves that run through the two sides of the support are symmetrically arranged, and a plurality of fasteners are evenly arranged on the support along the guide groove direction, and each fastener includes a bracket, an adjustment rod and a clamping plate, and two sliders are arranged on the bracket, and the bracket is arranged on the guide grooves on both sides of the support through the two sliders, and the clamping plate is arranged above the V-shaped groove and movably connected to the frame body through the adjustment rod. Compared with the prior art, the present invention makes the clamping of the long shaft more reasonable during the processing process, and the clamping stability and reliability are better by reasonably designing the structure of the clamp, effectively improving the processing quality of the long shaft, and reducing the defective rate of the production line to a minimum, and the fixture has a simple structure, is extremely convenient to disassemble and assemble, saves time and effort, effectively improves production efficiency, and produces higher economic benefits; therefore, it has a very broad application prospect.

[0004] Based on the above, the existing fixtures generally clamp shaft parts through the chuck structure. When the staff inspects whether there are defects on the surface of the shaft parts, they turn the shaft parts inside the chuck. Since the surface of the shaft parts is consistent, it is difficult for the staff to tell whether the shaft parts have rotated one circle when turning the shaft parts, resulting in a long time for inspecting the shaft parts, affecting work efficiency.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and an adjustable clamp is provided to achieve a purpose with greater practical value. Utility Model Content
