Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of polishing machine, the swelling device on particularly a kind of polishing machine.
Background technology
Polishing machine is mainly used in the polishing and the deburring processing of workpiece.When polishing machine was worked, workpiece was under the effect of sand belt, and generation is collided tempestuously and rubbed each other, with the workpiece polishing, and high efficiency, crudy is good, therefore has been widely used in the production and technology in a plurality of industries.
Existing plain grinding polishing machine generally has driving wheel and driven pulley, driving wheel and driven pulley are with the sand belt of ring-type, for allow sand belt can be between driving wheel and driven pulley tensioner, an expansion tightening wheel also is housed in sand belt, by regulating expansion tightening wheel, also be to change after expansion tightening wheel comes sand belt to unclamp when changing sand belt by regulating with the sand belt tensioner.The plain grinding polishing machine of this structure since many expansion tightening wheels with and attached mechanism, make the volume of polishing machine become big, need take bigger working space, in addition since have expansion tightening wheel with and attached mechanism, make the structure of polishing machine complete machine numerous and diverse.
For this reason, people begin the polishing machine of design improved, make its volume minimizing and structure more simplify.As China Patent No. is ZL200520040896.2 " belt sander abrasive band adjusting device " by name, be effective degree of tightness to be carried out in the abrasive band regulate, mainly be on the flat board up and down of belt sander body, to put frame one lifting guiding element on its structural design, handle is revolved in the adjustment that is pivoted on a lateral shelf plate of body, both link with an orthogonal driving gear set blocking, revolve the turn lifting of controlling the lifting guiding element by adjustment.This structure relies on the lifting guiding element to make the abrasive band tensioner, though saved expansion tightening wheel and attached mechanism, this structure can't be carried out tensioner automatically, needs whether tensioner of frequent inspection, makes troubles to operating personnel.
In addition, the tensioner governor motion of the tape handler of using on the other machines also is not suitable for being applied in the polishing machine.
Summary of the invention
The objective of the invention is the above-mentioned problem that exists at the swelling device of existing polishing machine, provide a kind of and simple in structurely, convenient use, the swelling device of polishing machine that can automatic tension.
Purpose of the present invention can realize by following technical proposal: a kind of swelling device of polishing machine, polishing machine comprises frame and the driving wheel and the driven pulley that are arranged on the frame, this swelling device is between driven pulley and frame, it is characterized in that, this swelling device comprises a guide cylinder and connecting rod, guide cylinder is connected on the frame, connecting rod is through in the guide cylinder and the outer end of connecting rod is stretched out guide cylinder and is connected with above-mentioned driven pulley, be provided with between connecting rod and the guide cylinder and make driven pulley, and also be provided with on the connecting rod and can promote driven pulley to the close thrust mechanism of driving wheel to the spring that moves away from the driving wheel direction.
The swelling device of this polishing machine is to be used for tensioner to be set to sand belt on driving wheel and driven pulley, is convenient for changing the device of sand belt simultaneously after sand belt is scrapped.In this programme, driving wheel is to be rotatably mounted on the frame, driven pulley be connected on the outer end of connecting rod and by swelling device can away from or near driving wheel, the outer end of the connecting rod here is meant the end of connecting rod away from driving wheel.Connecting rod is to be through in the guide cylinder, therefore can be in guide cylinder back and forth slip.When changing sand belt, with the close driving wheel of driven pulley, because the spacing of driven pulley and driving wheel is dwindled, new sand belt can be lifted down and replace with to sand belt easily by thrust mechanism; More finish changing, under the effect of spring, driven pulley makes sand belt be in the tensioner state away from driving wheel always.
