Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to an adjustable clamp for machining shaft sleeves. Background Art

[0002] The sleeve is a cylindrical mechanical part that is sleeved on the rotating shaft and is a component of the sliding bearing. Generally speaking, the sleeve and the bearing seat adopt an interference fit, and the shaft adopts a clearance fit. The bearing is a component that fixes and reduces the load friction coefficient during the mechanical transmission process. The similarity between the sleeve and the bearing is that both bear the load of the shaft, and the difference between the two is that the sleeve is an integral structure, and the shaft and the sleeve move relative to each other when rotating. In essence, the sleeve is actually a kind of sliding bearing. In the field of mechanical processing, the process equipment used to fix the processing object so that it has the correct position to accept the construction is called a fixture. The use of fixtures can give full play to the potential of existing equipment, enable workers to master the processing of complex parts, and improve production efficiency. During the processing of the sleeve, the sleeve is usually clamped from the outside.

[0003] The existing sleeve clamp, for example, a sleeve processing clamp with announcement number CN215880855U, includes a mounting seat, a chuck connected to the mounting seat, an inner support assembly connected to the chuck for pressing against the inner wall of the sleeve, and an outer resistance assembly connected to the chuck for pressing against the outer wall of the sleeve, wherein the inner support assembly and the outer resistance assembly cooperate to clamp the sleeve, and the inner support assembly includes a support plate slidably connected to the chuck and a driving member connected to the chuck, wherein the driving member is used to drive the support plate to move closer to or away from the axis of the chuck. This has the effect of reducing the possibility of sleeve deformation, but the clamp lacks the adjustability of the longitudinal clamping range.

[0004] Therefore, it is necessary to invent an adjustable fixture for shaft sleeve processing to solve the above problems. Utility Model Content

The mounting hole is fixed with a screw to install a cylinder, and the cylinder rod is driven to move by the cylinder, thereby pushing the adjustment plate to move, and the adjustment plate drives the lateral adjustment clamp to move the clamping sleeve.

[0010] Preferably, two groups of sliding holes and one group of threaded holes are opened on the side plate inside the adjustment frame, and a connecting platform is provided on the rear side surface of the adjustment frame.

[0017] 3. The design of the adjustable fixture can reduce the number and cost of fixtures caused by different sizes of sleeves requiring different fixtures, thereby reducing production costs. The adjustable fixture can adapt to sleeves of different sizes, so that the same machine tool can process sleeves of different specifications, enhancing the adaptability of the production line.
