Embodiment Construction
[0013] The longitudinal synchronous belt transmission mechanism of the workbench of the surface grinder includes a manual feeding device, a driving pulley 4, a driven pulley 9 and a synchronous belt 8. The manual feeding device includes a handwheel 1, a handwheel shaft 3 fixedly connected to the handwheel 1, and a handwheel shaft seat 2. The front part of the handwheel shaft 3 is erected in the handwheel shaft seat 2 through a bearing, and the handwheel shaft seat 2 is fixed on the surface grinder carriage 6. Outer side, hand wheel shaft 3 rear sections stretch in the carriage 6. The synchronous belt 8 is a closed adhesive tape with equidistant teeth on the surface of an inner circumference, and a metal skeleton is arranged in the middle of the adhesive tape. The driving pulley 4 and the driven pulley 9 are belt pulleys matched with the synchronous belt 8. During transmission, the synchronous belt 8 meshes with the driving pulley 4 and the driven pulley 9 with multiple teeth r...

The invention provides a longitudinal synchronous belt transmission mechanism of a surface grinder workbench, which relates to machine tool transmission components and is applied to small manual surface grinders. The transmission mechanism comprises a manual feeding device, a driving belt wheel, a driven belt wheel and a synchronous belt and is characterized in that: the manual feeding device comprises a hand wheel and a hand wheel shaft fixedly connected with the hand wheel, wherein the hand wheel shaft is spanned over a surface grinder dragging plate; the synchronous belt is a sealed adhesive tape of which the inner circumferential surface is provided with equidistant teeth; the driving belt wheel and the driven belt wheel are belt wheels matched with the synchronous belt; during transmission, the synchronous belt and the belt wheels are in multi-tooth meshing; the driving belt wheel is radially fixed at the tail end of the hand wheel shaft; the driven belt wheel is spanned over the surface grinder dragging plate; and the synchronous belt is fixedly connected with a synchronous belt fixing seat fixedly connected on the workbench. The transmission mechanism has the advantages of reasonable structure, no relative slip or meshing clearance and stable and uniform transmission.
Description
technical field [0001] The invention relates to a transmission part of a machine tool, which is applied to a small manual surface grinder. Background technique [0002] Existing small manual surface grinders, the movement of the workbench is: by turning the handwheel, through the meshing of the gear and the internal gear on the sheave, the motion is transmitted to the sheave, and the workbench is pulled by the wire rope wound on the sheave Make vertical movement; adjust the tightness of the wire rope by adjusting the adjusting bolt on the right end of the workbench to fix the wire rope seat. Although the transmission mechanism is simple in structure and easy to operate, it also has the following defects: 1. The steel wire rope is easily broken after a long time of operation; fall, causing danger. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects and provide a longitudinal synchronous belt transmission mechan...
