Abstract

The utility model provides a grinding machine, comprising a rack and a horizontal machine bench disposed on the rack. The grinding machine is characterized in that the machine bench is provided with a rotating shaft; the rotation of the rotating shaft is driven by an externally-installed three phase motor; the rotating shaft is provided with a pair of fixed blocks; the fixed block is provided with a groove for fixing a member to be grinded between two fixed blocks, and the member to be grinded sleeves the rotating shaft; the machine bench and the outer sides of a pair of fixed blocks are respectively provided with a grinding brush capable of freely sliding along the central axis of the rotating shaft; sand papers are disposed on the contacting surface of the grinding brush and the member to be grinded. The grinding machine is advantageous in that the structure is simple and the operation is easy; a rotating shaft can be replaced based on the size of the member to be grinded, and rotating speed can be adjusted; the specification of sand paper on the grinding brush can be adjusted based on the grinding degree, and different grinding requirements of clients can be met; the grinding machine also has dust-preventing and dust-collecting function.

Description

A kind of sander

Technical field

The utility model relates to a kind of sander, particularly relates to a kind of sander that is specifically designed to the polishing central tube.

Background technology

The surfaces externally and internally of a lot of machine components, product all will be polished, polishing, to improve surface smoothness.Under the increasing situation that applies to seawater desalination system of current reverse osmosis technology; Central tube has very important effect as the important parts that catchment of reverse osmosis equipment, and central tube uses super glue to connect in connection procedure; It is higher that but central tube is extruded surface smoothness; Be easy to generate and come unstuck, through the polishing of central tube two ends surface roughness being realized the raising of central tube tightness, to guarantee to catchment purity.At the grinding apparatus that also is not specifically designed to the polishing central tube in the market; Internal production adopts the hand sand mode, has a strong impact on operating efficiency like this, is difficult for grasping the polishing degree; The fraction defective of product is higher, and also there is the healthy infringement that causes to the workman in artificial simultaneously polishing.

Summary of the invention

The utility model is accomplished in order to solve deficiency of the prior art, and the purpose of the utility model provides a kind of sander that is specifically designed to the polishing central tube, and it has the grinding efficiency height, can adjust the function of polishing degree and control of dust according to actual needs.

The technical scheme of the utility model is:

A kind of sander; Comprise frame and the board that is erected at the level on the frame, it is characterized in that: on said board, be provided with rotating shaft, the rotation of said rotating shaft is driven by the three phase electric machine of peripheral hardware; A pair of fixed block is set on the said rotating shaft; Fluted on the said fixed block, be used for parts to be polished are fixed between two fixed blocks, and parts to be polished are set on the said rotating shaft; On said board and in the outside of said a pair of fixed block, respectively be provided with one can be in the board upper edge abrasive brush that is free to slide of the central axis of rotating shaft, equip sand paper on the said abrasive brush with on the parts contact-making surface of waiting to polish.

Further, the technical scheme of the utility model can also be:

The specification of said sand paper polishing precision is as required adjusted replacing.

Also be provided with dust cover to be opened/closed on the said board, the rear portion perforate of said dust cover is connected with outside dust arrester through dust leg.

The front end of said board also is provided with the conveying bar; Said conveying bar comprises up and down and to send part bar and a pair of addressee bar down on be provided with a pair of; Send the part bar to have a down dip towards the direction of rotating shaft is oblique on said, be used for parts to be polished are delivered to fixed block, said addressee bar down is oblique having a down dip towards the board outside; And, be used to receive the parts of being polished at its terminal upwards turnover formation plug.

The sander of the utility model is simple in structure; Processing ease; Can change corresponding rotating shaft and regulate rotary speed to the size of the parts of waiting to polish; And the specification of the sand paper on the degree of the polishing as required adjustment abrasive brush, can satisfy client's different polishing demand, and have dustproof dust collection function.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further explain.

A kind of sander of the utility model; Comprise frame 1 and the board 2 that is erected at the level on the frame, on board, be provided with rotating shaft 3, the rotation of rotating shaft is driven by the three phase electric machine 4 of peripheral hardware; A pair of fixed block 5 is set on the rotating shaft 3; Fluted 6 on the fixed block 5, be used for the parts (not shown) of waiting to polish is fixed between two fixed blocks, and parts to be polished are set on the rotating shaft 3; On board 2 and in the outside of a pair of fixed block, respectively be provided with one can be in the board upper edge abrasive brush 7 that is free to slide of the central axis of rotating shaft, on the abrasive brush with the parts contact-making surface of waiting to polish on equipment sand paper (not shown).

In this example, the specification of sand paper can be at any time as required polishing precision adjust replacing.

In this example, on board, also be provided with dust cover 8 to be opened/closed, the rear portion perforate of dust cover 8 is connected with outside dust arrester 10 through dust leg 9.

In this example, the loading and unloading of the parts of polishing for ease also are provided with the conveying bar at the front end of board; Carry totally two pairs of bars, comprise and send part bar 11 and a pair of addressee bar 12 down on be provided with up and down a pair of, on send part bar 11 to have a down dip towards the direction of rotating shaft is oblique; Be used for parts to be polished are delivered to fixed block; Following addressee bar is oblique having a down dip towards the board outside, and form plug 13 in its terminal upwards turnover, is used to receive the parts of being polished.

The operation principle of the sander of the utility model is:

Will parts polished be central tube through on send the part bar to deliver to fixed block; And it is fixed, on abrasive brush and face that two end faces to be polished central tube contact, paste and specify specification sand paper, and the position of adjustment abrasive brush; Make coated abrasive surface and treat that buffed surface fits tightly; The rotation of rotating shaft drives the rotation of central tube, thus two end faces of polishing central tube, and the polishing back receives through following addressee bar under the gravity effect and it is transferred to Turnover Box; Dust gathering arrester can prevent that dust from splashing in polishing simultaneously, with the dust collection after the polishing.

Above-mentionedly only several kinds of specific embodiments in the utility model are explained; But can not be as the protection domain of the utility model; Every equivalence of having done according to the design spirit in the utility model changes or modifies, and all should think the protection domain that falls into the utility model.
