Description

The electric turnover machine

Technical field

The utility model relates to a kind of object tipping arrangement, particularly electric turnover machine.

Background technology

The electric turnover machine is mainly used in casting sandbox, model and large-scale workpiece upset operation.China Patent No. is that 91221835.5 patent documentation discloses a kind of electronic suspension positioning machine, it relies on motor drives screw mandrel and nut to mesh, thereby the affixed U type shift fork of drive and nut moves, U type shift fork drives sprocket wheel again and moves axially on transmission shaft, to regulate the spacing between the hoist cable.This structure has the following disadvantages: screw mandrel processing request height, and when particularly length was longer, its right alignment was difficult to guarantee the tooling cost height; Transmission shaft is born sprocket wheel and workpiece weight, and flexible distortion need add the big drive shaft diameter, increases cost; Sprocket wheel is axially spacing by U type shift fork, and when workpiece produces when rocking, the dropper belt movable sprocket rocks, and shift fork can't stably limit sprocket wheel and rocks, and influence normal running, and easily causes the distortion of shift fork, reduction service life.

Summary of the invention

The purpose of this utility model is to provide a kind of processing and manufacturing of being convenient to, and transmission shaft is difficult for the electric turnover machine that flexural deformation and traction wheel are difficult for rocking.

In order to achieve the above object, the technical solution adopted in the utility model is: a kind of electric turnover machine, has girder, the upset motor reducer, transmission shaft, traction wheel, hoist cable and traction wheel running gear that the left and right sides is arranged, the upset motor reducer is captiveed joint with girder, and the upset motor reducer drives and connects transmission shaft, traction wheel and hoist cable are in transmission connection, and the traction wheel running gear is installed on the girder movably; The traction wheel running gear comprises walking frame, running motor reductor and drive wheel; Walking frame is provided with the bearing seat that is positioned at the traction wheel both sides; Bearing is housed on the bearing seat, is supported with sleeve in the bearing, traction wheel is fixed on the sleeve, and sleeve and transmission shaft be normal-running fit and axial sliding fit synchronously circumferentially.

After adopting said structure, because the traction wheel running gear comprises walking frame, running motor reductor and drive wheel, the traction wheel running gear is installed on the girder movably, screw mandrel, nut, U type shift fork structure have been cancelled, only adopted drive wheel on girder, to move, so, not high to the precision and the matching requirements of parts, be convenient to processing and manufacturing, tooling cost is also low.In addition, because walking frame is provided with the bearing seat that is positioned at the traction wheel both sides; Bearing is housed on the bearing seat, be supported with sleeve in the bearing, traction wheel is fixed on the sleeve, sleeve and transmission shaft be normal-running fit and axial sliding fit circumferentially synchronously, so transmission shaft do not bear traction wheel and workpiece weight, and the weight of traction wheel and workpiece is to be delivered on the walking frame by bearing by sleeve, walking frame is delivered on the girder again, so transmission shaft is difficult for flexural deformation, need not adopt the major diameter transmission shaft, save cost; In addition, traction wheel and sleeve stably are bearing in the bearing, and the traction wheel position stability is difficult for rocking, can be reposefully with moving axially long service life about the bearing seat on the walking frame.
