Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments. It is to be understood that the described embodiments are merely a few embodiments of the utility model, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "central," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientation or positional relationship indicated in the drawings for convenience in describing the utility model and for simplicity in description, and are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated in a particular manner, and are not to be considered limiting to the scope of the present invention.

In the figure, a lower base plate 100; a support plate 200; a linear bearing 300; a linear bearing mount 400; a lift cylinder 500; a bearing mounting block 600; a rolling ball bearing 700; a stop block 800; a rising plate 900; bearing grooves 1000.

As shown in fig. 1, the improved structure of the welding floating platform comprises a lower base plate 100, an upper plate, a support plate 200, a linear bearing 300, a linear bearing mounting seat 400, a lifting cylinder 500, a bearing mounting block 600 and a rolling ball bearing 700, wherein the rolling ball bearing 700 is mounted on the bearing mounting block 600 and can freely rotate, a fixture can be conveniently moved by using the rolling ball bearing 700, the bearing mounting block 600 is fixed on the upper plate 900, four linear bearings 300 for guiding are symmetrically arranged at two ends of the lower part of the upper plate 900, the linear bearings 300 are fixed on the lower base plate 100 by the linear bearing mounting seat 400, two lifting cylinders 500 are symmetrically arranged at two ends of the lower part of the upper plate 900, piston rods of the lifting cylinders 500 are fixedly connected with the support plate 200, the cylinder bodies of the lifting cylinders 500 are fixed on the lower base plate 100 by the cylinder mounting blocks, here, the lifting cylinders 500 can jack up or lower the upper plate 900, the replacement is convenient, a bearing groove 1000 is formed in the supporting plate 200, a bearing mounting block 600 for mounting the rolling ball bearing 700 can penetrate through the bearing groove 1000, and two limiting blocks 800 are arranged at the rear end of the supporting plate 200.

During operation, the lifting cylinder 500 is ventilated, and under the action of force, the lifting cylinder 500 lifts the lifting plate 900 through the cylinder piston rod, so as to drive the lifting plate 900 to move together and under the action of the four guiding linear bearings 300, so that the rolling ball bearing 700 moves up and down along the length direction of the linear bearing 300.

When the operator is subsequently waited for to change the mould, lift cylinder 500 lifts ball bearing 700, and ball bearing 700's rotation will guarantee that anchor clamps will carry out the translation along antifriction bearing's tangential, and this kind of mode of floating guarantees on the one hand that anchor clamps can easily move in the top of floating platform, and on the other hand also makes anchor clamps can only move along antifriction bearing's tangential and can not take place the removal of other directions. In addition, when the fixture moves to the position near the correct position, the limiting block 800 at the rear end of the supporting plate 200 limits the fixture to move continuously, so that the fixture is guaranteed to move right above the correct position, the lifting cylinder 500 is exhausted at the moment, the lifting plate 900 drives the rolling ball bearing 700 to descend into the groove in the supporting plate 200, the fixture falls onto the supporting plate 200 at the moment, the fixture is separated from the rolling ball bearing 700, and when the mold needs to be disassembled subsequently, the actions are repeated.

The specific embodiments described herein are merely illustrative of the spirit of the utility model. Various modifications, additions and substitutions for the described embodiments may be made by those skilled in the art without departing from the scope and spirit of the utility model as defined by the accompanying claims.
