Permanent magnet guide device for semi-automatic welding trolley

Abstract

The invention relates to a permanent magnet guide device for a semi-automatic welding trolley. The guide device comprises a bracket, wherein one side of the bracket is provided with permanent magnets and fixed on the semi-automatic welding trolley through a fixing connecting plate; the other side of the bracket is connected with the fixing connecting plate, attracted to a plate beam rib plate through the permanent magnets and in contact with the plate beam rib plate; and the permanent magnets are not in contact with the plate beam rib plate. The guide device has a simple structure and runs reliably; the bracket is attracted to the plate beam rib plate under the action of magnetic force of the permanent magnets, but the permanent magnets are not in contact with the plate beam rib plate, so that resistance produced when the bracket moves is eliminated, bracket bearings are only attracted and attached to the plate beam rib plate due to the action of the magnetic force, and high positioning accuracy is achieved; meanwhile, the bracket is arranged on the semi-automatic welding trolley through the fixing connecting plate, so that an effect of guiding and positioning the semi-automatic welding trolley is achieved, and the guide device is easy and convenient to operate.

Description

technical field [0001] The invention relates to a semi-automatic welding trolley, in particular to a guiding device for a semi-automatic welding trolley. Background technique [0002] It is transformed into a semi-automatic fillet welding machine by using a semi-automatic welding trolley, which has the characteristics of low cost, simple operation, and multiple functions in one machine. However, the semi-automatic welding trolley must be guided by guide rails. Usually, guide wheels are set at the front end of the semi-automatic welding trolley, and the guiding of the semi-automatic welding trolley is realized by moving the guide wheels on the guide rails. During the welding process, sometimes the welding seam is too long, and the guide rail needs to be placed repeatedly, which is cumbersome and time-consuming; and it is greatly affected by the space, so it cannot be positioned accurately, and the positioning accuracy is poor.
