Abstract

The invention relates to a polishing machine, which comprises a frame, a driving mechanism, a first rotating shaft, a second rotating shaft, close-loop type abrasive paper sheathed on the first rotating shaft and the second rotating shaft, and an adjustment device respectively arranged on the both ends of the second rotating shaft, wherein the adjustment device comprises a locating rod respectively extending to the both ends along the second rotating shaft, a locating block respectively fixed on the both ends of the second rotating shaft and provided with an opening part, and an adjusting bolt arranged on the locating block and used for adjusting a distance between the first rotating shaft and the second rotating shaft. According to the invention, by matching the locating rod arranged on the both ends of the second rotating shaft, and the adjusting bolt used for adjusting the distance between the first rotating shaft and the second rotating shaft, the adjusting bolt is further docked with the locating rod to ensure degree of tightness of the abrasive paper on the first rotating shaft and the second rotating shaft, so that the surface of a work-piece is uniformly grinded by the abrasive paper along upper end faces of the first rotating shaft and the second rotating shaft, thus the processing effect and the quality of the polishing machine are improved.

Description

A kind of polishing machine

Technical field

the invention belongs to field of machining, are specifically related to a kind of polishing machine.

Background technology

are present; Polishing machine by base, dump, primary element such as polishing fabric, polishing cover and lid forms; Motor is fixed on the base; The tapered sleeve that the fixing polishing dish is used links to each other with motor reel through screw; Polishing fabric is fastened on the polishing disk through lasso, and after motor started through the switch connection power supply on the base, just available hand was exerted pressure to sample and on the polishing disk that rotates, polished; The polishing fluid that adds in the polishing process can flow into and to place in the other square plate of polishing machine through being fixed on drainpipe in the vinyl disc on the base, and polishing cover and lid can prevent that dirt and other foreign material from dropping on the polishing fabric and influence result of use when machine does not use.

According to above-mentioned polishing machine, the polishing fabric wearing and tearing are bigger, and manually sample exerted pressure ; Dynamics is difficult to control, and the polishing fabric surface abrasion is inhomogeneous like this, and some local wearing and tearing is more serious; Even some place do not touch, and makes whole polishing fabric surface rough curved surface occur, directly influenced the smoothness and the precision of surface of the work; The stock removal polishing fabric is once changed in polishing, and production cost is bigger, in order to practice thrift the loss of polishing fabric; Adopt sand paper to replace polishing fabric, saved apparatus such as dump, simplified polissoir; Therefore, novel polishing machine by base, drive motors, two can be around the rotating shaft of self rotation, be set in the sand paper that is closed-loop type on two rotating shafts, one of them rotating shaft is connected with the driving shaft belt transmission of drive motors; By the rotation of drive motors, driving the rotating shaft that is connected with the driving shaft belt transmission and rotating, and then drive is set in two sand paper uniform motion on the rotating shaft; Be in the sand paper that connects a rotating shaft upper surface this moment and grinding the surface of workpiece uniformly, thereby reach polishing effect, however long-term wearing and tearing; It is more and more longer to be set on two rotating shafts sand paper, and what sand paper was loose is set on two rotating shafts, is in the surface that the sand paper of two rotating shaft upper surfaces can not grind workpiece uniformly this moment; The surface of the work that makes easily is uneven, thereby has influenced surface of the work smoothness and precision, makes troubles to polishing.

Summary of the invention

technical problem to be solved by this invention is the deficiency that overcomes prior art, and a kind of improved polishing machine is provided.

For solving above technical problem, a kind of technical scheme that the present invention takes is:

a kind of polishing machine; It comprises frame, driving mechanism, respectively be erected at the frame two ends first rotating shaft and can around second rotating shaft of self axial line rotation and be set in first rotating shaft and second rotating shaft on the sand paper that is closed-loop type; First rotating shaft is connected with the driving shaft belt transmission of driving mechanism; Be fixed with workbench on the frame; Described workbench supporting sand paper and be in first rotating shaft and second rotating shaft between; Polishing machine also comprises the adjusting device that is separately positioned on second rotating shaft terminal; Its adjusting device comprises respectively the backstay that extends along the second axial rotary two ends, be separately fixed at second rotating shaft terminal and have the locating piece of peristome and be arranged on the adjusting bolt that is used to regulate first rotating shaft and the second rotating shaft wheelbase on the locating piece; Backstay comes and goes at the peristome of locating piece and moves, locating piece be provided with parallel with the second rotating shaft axial connecting line with first rotating shaft and with regulate the adjusting bolt hole that bolt matches, regulate that bolt one end is conflicted on backstay, the other end and adjusting bolt hole threaded engagement.

preferably, the elasticity of sand paper on first rotating shaft and second rotating shaft is guaranteed to be set in the bar heart of backstay and the second rotating shaft axle center on same straight line.

more preferably, second rotating shaft comprise with the rotating shaft core, be fastened on the rotating shaft core bearing and with the close-fitting cylinder in the bearing outside.

Because the employing of technique scheme, the present invention compared with prior art has the following advantages:

the present invention adopts and to be arranged on the backstay of second rotating shaft terminal and to be used to regulate cooperating between the adjusting bolt of first rotating shaft and the second rotating shaft wheelbase; Further by regulating bolt conflict backstay; Guaranteed to be in the sand paper elasticity on first rotating shaft and second rotating shaft, thereby guaranteed that sand paper is grinding surface of the work uniformly along first rotating shaft and the second rotating shaft upper surface, thereby improved the processing effect and the quality of polishing machine; In addition; The present invention is simple in structure, and it is convenient to implement, and cost is lower.
