A lifting device for machining

Abstract

The invention discloses a hoisting device for mechanical processing. The device comprises a base, universal wheels, a concave-opening seat, a bolt, a locking nut, a rotating plate, a lead screw, a chuck, a handle, an outer pipe, an inner pipe, a locking part, a cross bar, a rack, a gear mounting rod, a gear, a belt and a first motor. According to the device, the hoisting is mechanically carried out, so that the defect of manual hoisting in the background technology can be avoided; the universal wheels enable moving; the handle can be rotated, and the chuck sucks the ground to avoid slipping; the gear is driven to rotate through the first motor, and the rotating gear drives the rack to move, and thus the height of the whole device can be adjusted; the inner pipe slides in the outer pipe torealize supporting; a second motor drives a first steel cable to enable a lifting rod to slide up and down, and thus the height of the whole device is adjusted; a part is clamped through a clamping device, and the clamping device is hoisted through a coiling motor to realize hoisting assembling; the clamping device is of a plurality of structures for replacing in order to hoist the parts with different specifications.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a lifting device for machining. Background technique [0002] Machining refers to the process of changing the shape or performance of a workpiece through a mechanical device. According to the difference in processing methods, it can be divided into cutting processing and pressure processing. The production types are usually divided into three categories: 1. One-piece production: Products of different structures and sizes are produced individually, with few repetitions. 2. Mass production: The same product is manufactured in batches throughout the year, and the manufacturing process has certain repetitions. Mass-produced parts Mass-produced parts3. Mass production: A large number of products are manufactured, and most workplaces often repeat a certain process of a certain part. [0003] At present, when lifting large parts in mechanical processing, there are problems: 1. Th...
