Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to an adjustable fixture for hoisting the bottom of a hydraulic cylinder. Background Art

[0002] When machining the liquid passing holes and turning the stop mouths of the bottom of the hydraulic cylinder, hoisting is required. For the bottom of large cylinders, as shown in Figure 1 、 2 、3, and for the bottom of medium cylinders, as shown in Figure 4 、 5 、6. Due to their irregular shapes, it is not very convenient to use suction cups and slings. There are many types of cylinder bottoms, and the size differences of each type of cylinder bottom are relatively large. For example, most of the bottoms of large cylinders are hemispherical, with two ears and multiple liquid passing nozzles on the side. Due to their irregular shapes, in most cases, the state placement before processing is completed by combining slings and manual labor, which is not only laborious but also unsafe. Content of the Utility Model

[0011] Further preferably, a anti-falling pin hole is provided at the tail of the adjusting screw, and a pin is inserted into the anti-falling pin hole.

[0012] During operation, a hook is provided at the bottom of the longitudinal suspension rod, and a plurality of clamping position adjusting screw holes are provided thereon. The clamping position screw can be installed according to the type of the cylinder bottom and the size of the inner hole to facilitate hoisting; the lifting lug is used for the installation of an external sling or an external hook; the knob handle can conveniently adjust the position of the fixture when clamping the cylinder bottom; the stroke adjusting screw can adjust the stroke according to the thickness of the cylinder bottom and has a anti-falling pin hole at its tail to prevent the adjusting screw from falling when the adjusting stroke is too large. The adjusting nut is welded to the upper part of the longitudinal suspension rod and is used in cooperation with the adjusting screw; the baffle is used to clamp the outer circle of the cylinder bottom to prevent the cylinder bottom from falling, and a knob handle is installed on the baffle to facilitate the operator to adjust the position of the baffle; before clamping the cylinder bottom, the adjusting screw is adjusted to a suitable position for convenient clamping. The inner hole of the cylinder bottom is hooked by the hook or the clamping position screw (anti-collision rubber is installed at the contact part between the fixture and the forming surface of the cylinder bottom), and then the baffle is lowered to clamp the outer circle of the cylinder bottom, and it is hoisted to a suitable position, the baffle is rotated up and the hook is taken out to complete the hoisting work.

[0014] 1) The fixture of the present invention has strong versatility. Since the fixture can be adjusted in multiple directions, it can hoist various types of cylinder bottoms.

[0015] 2) The fixture of the present invention reduces the labor intensity of workers. Workers no longer need to use manpower to carry and clamp and adjust the drilling direction.

[0016] 3) The hoisting process of the fixture of the present invention is safer. Previously, using manpower to carry or slings were prone to cause the workpiece to fall during the hoisting process, resulting in safety accidents.

[0017] 4) The fixture of the present invention improves the hoisting efficiency. Now using the new hoisting auxiliary tool can increase the hoisting speed of the upper and lower workpieces by at least twice compared with before.
