Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Referring to fig. 1, the present embodiment provides a workbench for bucket machining, including an installation frame 4 and a driving motor 1 fixedly installed on the upper end of the installation frame 4, a winding drum 2 is rotatably installed on an output shaft of the driving motor 1, a chain 3 is wound on the winding drum 2, a lifting hook 5 is fixedly installed at the bottom end of the chain 3, a base is fixedly installed at the lower end of the installation frame 4, two cylinders 10 are installed on the base, a supporting plate 9 fixedly installed on the installation frame 4 is arranged above the base, piston rods of the cylinders 10 penetrate through the supporting plate 9, and supports 6 are symmetrically and fixedly installed at the top ends of piston rods of the two cylinders 10. During the use, treat welded built-up part with the bucket and place in backup pad 9, and remove two cylinders 10 and make two supports 6 grasp the bucket, when the bucket needs to carry out the removal of little distance on backup pad 9, can remove the relative position between the cylinder 10 or remove the position of two cylinders 10 simultaneously, make the bucket realize the lift or the horizontal bulk movement of little distance, in addition when needs bucket slope is placed, two cylinders 10 can go up and down different height and cause the ascending difference in height of vertical side, make welding personnel can weld the bottom of bucket, when the bucket needs to carry out the transportation of great distance, lift the bucket with lifting hook 5 and transport.

Please refer to fig. 1, which is a preferred embodiment of the present invention: the bottom fixed mounting of cylinder 10 has connecting rod 12, the bottom fixed mounting of connecting rod 12 has the joint board 11 that the slip set up in spout 13 on the base. During the use, joint board 11 slides in spout 13, but joint board 11 blocks again and locates in spout 13, can not break away from in the spout 13, guarantees the stability that cylinder 10 removed, moves along spout 13 all the time.

Referring to fig. 1-3, as another preferred embodiment of the present invention: the supporting plate 9 is provided with a guide groove 14 used for sliding of a piston rod of the air cylinder 10, a guide plate 15 is arranged in the guide groove 14 in a sliding mode, clamping grooves 19 clamped on the supporting plate 9 are formed in two sides of the guide plate 15, a limiting hole 18 used for placing the piston rod of the air cylinder 10 is formed in the guide plate 15, and a fixing assembly is arranged on the guide plate 15. In use, when the cylinder 10 is moved, the guide plate 15 slides in the guide groove 14 along with the cylinder 10, when the cylinder 10 reaches a designated position, the guide plate 15 is fixed by the fixing component, and the cylinder 10 is also fixed because the piston rod of the cylinder 10 passes through the limiting hole 18.

Please refer to fig. 3, which is another preferred embodiment of the present invention: the fixing assembly comprises a bolt 16 arranged in the guide plate 15, the bolt 16 is in threaded fit with the guide plate 15, a gear is fixedly arranged at the lower end of the bolt 16, and two racks 17 meshed with the gear at the bottom end of the bolt 16 are arranged in the guide plate 15 in a sliding mode.
