Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, and more specifically, to a slotting machine for processing solid elevator guide rails. Background Art

[0002] Elevator guide rails arranged in an elevator hoistway must be joined end-to-end to ensure excellent straightness after connection. To achieve this required straightness, a single elevator guide rail is typically provided with a positioning protrusion at one end and a positioning groove at the other end that matches the positioning protrusion. The positioning groove requires post-processing, but dedicated processing equipment is currently unavailable, making the groove difficult to manufacture and resulting in poor alignment with the positioning protrusion at the other end, resulting in poor overall results. Accordingly, this utility model proposes a slotting machine for processing solid elevator guide rails. Utility Model Content

[0019] In this embodiment, the first support plate 8 and the second support plate 9 are first used to pre-position the solid elevator guide rail to be grooved on the top plate 2, so that one end thereof is against the first support plate 8 and one side is against the second support plate 9, thereby completing the positioning in the length and width directions; then the milling power head 5 is started to rotate the upper milling cutter 6 at high speed, and then the drive motor 12 is started, and the movable bracket 4 carries the milling power head 5 downward relative to the fixed bracket 3 through the screw pair. During this period, one end of the solid elevator guide rail encountered is grooved to complete the processing of the corresponding groove. Finally, after resetting and stopping the milling cutter 6, the elevator guide rail can be removed.
