Description

The workbench of belt sander
Technical field
The invention belongs to technical field of operation, relate to a kind of belt sander, particularly a kind of workbench of belt sander.
Background technology
Belt sander is for grinding work piece outer surface, improves the device of workpiece fineness.Belt sander processing is adopted to have the advantage that production efficiency is high and product percent of pass is high; Be widely used in every field thus, especially in five metals, hot-water heating and furniture industry.
The kind of belt sander is more, as a kind of flat grinding abrasive belt polishing machine [application number: 200610118511.9 proposed before applicant; Authorization Notice No.: CN1962191B], comprise the frame that has workbench, frame is provided with the rotating shaft be connected with actuating unit, rotating shaft is connected with driving wheel, frame is also provided with driven pulley and regulating wheel, driving wheel, driven pulley and regulating wheel are socketed with abrasive band, above-mentioned workbench is close to abrasive band and be arranged in parallel with abrasive band, frame is provided with column, and above-mentioned regulating wheel is located at column place, and between regulating wheel and column, be provided with the tensioning apparatus that can make regulating wheel movement.When utilizing this polishing machine grinding work piece, workpiece is fixing treats that flour milling is necessary for horizontal plane on the table, completes workpiece ground feeding by self-powered platform.
And for example a kind of vertical abrasive belt grinder [application number: 00259206.1 of applicant's design of a TaiWan, China; Authorization Notice No.: CN2449871Y], the object disposing platform of an adjustable lifting is established above board, a vertical type shelf is established again in board side, set to open at vertical type shelf epimere and establish wheel, vertical type shelf top is opened and establishes wheel, establish wheel to establish one group of abrasive band by two, and only make to manifest below abrasive band dewiness with the coated isolation of a protecting box, establish an adapter to be connected dust-collecting equipment on protecting box top, lower the belt pulley establishing wheel one end to be connected coordinates a driving belt to link the motor of board inside.When utilizing this vertical abrasive belt grinder grinding work piece, workpiece is fixed on object disposing platform, is realized the feeding of workpiece by manipulation object disposing platform; This grinder utilizes the abrasive band appearing shape to carry out grinding.The table top of above-mentioned two kinds of workbench and the grinding section in abrasive band all process parastate, when to process between grinding face and locating surface and non-parallel time, then need cushion block to support workpiece, this causes fixation workpiece complex structure, and different workpiece also needs to develop cushion block pointedly, this also increases production cost.
Tape-alternation mechanism [the application number: 01254790.5 of a kind of abrasive band plate glazing calender and for example proposed before applicant; Authorization Notice No.: CN2505230Y], abrasive band plate glazing calender is made up of body, motor, driving wheel and driven pulley, and driving wheel and driven pulley to be all fixed on body and to be all positioned in same level.When utilizing this polishing machine grinding work piece, offhand is pressed in the surface in abrasive band from the top down, and the back side, abrasive band and body lean, and completes thus the fixing of workpiece and feeding simultaneously.When processing as triangular prism shape workpiece, because people hold stressed uneven with applying pressure, the stock removal of same side can be caused different, and then affect the precision of workpiece; Also can there is the problem that stable holding workpiece difficulty is large simultaneously.
Summary of the invention
The object of the invention is to there are the problems referred to above for existing technology, propose a kind of workbench of belt sander, the abrasive band function with this workbench avoid locating surface and grinding face non-parallel time problem to Workpiece fixing difficulty.
