专利汇可以提供Welding apparatus with guide means专利检索,专利查询,专利分析的服务。并且A welding apparatus having means for guiding a welding tool along a predetermined path. A welding tool is mounted to a folding arm swingably mounted to the frame of the apparatus. A linkage rod is bearingly mounted to the arm and projects into a slotted template. A slotted chain guide bearingly receives a continuous roller chain which is driven at a uniform speed by a motor sprocket combination. The linkage rod is connected to the chain thus moving with the chain and forcing the arm and welding tool at a uniform speed along a path determined by the template slot. A tracer is mounted to the linkage rod. The template on either side of the slot receiving the linkage rod projects into the tracer thereby preventing sideways disengagement of the tracer and rod from the template slot.,下面是Welding apparatus with guide means专利的具体信息内容。

1. Apparatus for guiding a tool along a path at a uniform speed comprising: drive belt means; a template having a first slot defining two dimensionally a desired tool path; a belt guide positioned in spaced relationship to said template and operable to guide said belt means parallel to said tool path; drive means connected to said drive belt means and operable to move said drive belt means at a uniform speed; a tracer connected to said drive belt means and engageable with and movable through said slot and guided by said slot during movement therethrough; and, connecting means attached to said tracer and connectable with a tool to be moved along said tool path.
2. The apparatus of claim 1 wherein: said drive belt means is a continuous flexible chain; and, said drive means is an electric motor and a sprocket in driving engagement with said chain.
3. The apparatus of claim 2 wherein: said belt guide includes guide plate means mounted to said template, and said plate means provide a second slot aligned with said first slot; and, said chain is a roller chain with end walls, said plate means extending inwardly of said end walls on both sides of said second slot for bearingly receiving said chain.
4. The apparatus of claim 1 wherein: said tracer has a pair of spaced apart guide walls connected together and a roller disposed therebetween, said guide walls being positioned externally of said template; and, said template extends inwardly of said guide walls bearingly receiving said roller.
5. The apparatus of claim 4 wherein: said connecting means is a rod extending through said tracer and connected to said belt means.
6. The apparatus of claim 4 wherein: said tool is a welding tool bearingly connected to said rod.
7. In a welding apparatus having a frame, a folding arm swingably mounted on said frame, a welding tool connected to said arm, the improvement which comprises: a template having a slot defining two dimensionally the desired path of said welding tool; a roD received by said arm; a tracer mounted to said rod and engageably movable through said slot; flexible belt means connected to said rod; driving means connected to said belt means and operable to drive said belt means at a uniform speed; and, a belt guide spaced from said template and receiving said belt means.
8. The apparatus of claim 7 wherein: said welding tool has a welding tip positioned centrally along a first axis extending centrally through said slot; said folding arm swings about another axis parallel to and spaced from said first axis; and, said rod is a spindle rotatable about said first axis.
9. The apparatus of claim 8 and further comprising: a first spacer connected to and between said template and said belt guide, said belt guide being a slotted plate; a mounting plate connected to said frame; and, a second spacer connected to and between said mounting plate and said slotted plate.
10. The apparatus of claim 9 wherein: said template extends on either side of said slot into said tracer preventing sideways disengagement therefrom.
11. Apparatus for guiding a tool along a tool path at a uniform speed comprising; a stationary guide having convex and concave edges defining said tool path two dimensionally; a first chain positioned adjacent and movable along said edges; a connector connecting said tool to said chain; and, driving means connected to said chain and operable to move said chain at a uniform speed along said edges defining said tool path two dimensionally to thereby move said tool along said path.
12. The apparatus of claim 1 wherein: said driving means includes a second chain, a motor drivingly engaging said second chain, a rotatably mounted rod with a first and second sprocket where said first sprocket engages said first chain and said second sprocket engages said second chain.
13. The apparatus of claim 11 and further comprising: a template ha.1ing a slot defining said tool path and in spaced relationship to said guide; and wherein: said connector includes a rotatably mounted rod with a roller shaped wall slidable through said slot.
