Abstract
The utility model relates to a grinding head for grinding machines, wherein a grinding plate makes straight reciprocating motion. The utility model solves the problems that the existing grinding head for grinding machines has a limitation of operating scope on an operating surface and can leave circular traces on a grinding surface. The grinding head for grinding machines comprises a grinding head hood and a main grinding plate which is arranged in the grinding head hood. The grinding head for grinding machines also comprises a main circular disc which is arranged on grinding head hood, and can be driven to rotate corresponding to the grinding head hood by a transmission shaft, wherein the main circular disc is connected with the main grinding plate through one link mechanism; the main grinding plate is driven to make the straight reciprocating motion corresponding to the grinding head hood through the link mechanism by the main circular disc which rotates main. As the improvement, an auxiliary circular disc and an auxiliary grinding plate are arranged in the grinding head hood, wherein the auxiliary circular disc is driven to rotate corresponding to the grinding head hood by the main circular disc; the auxiliary circular disc is connected with the auxiliary grinding plate through the other link mechanism; the auxiliary grinding plate is driven to make the straight reciprocating motion corresponding to the grinding head hood through the other link mechanism by the auxiliary circular disc which rotates main. The utility model overcomes the defect that the operating scope of the grinding head for grinding machines has a limitation on the operating surface, and provides a translation grinding head without operating limitation that a grinding plate moves horizontally. Because the grinding plate moves horizontally, the utility model can not leave the circular traces on the grinding surface.
Description
Technical field
The utility model relates to a kind of bistrique of sander that use, that operation surface is polished in decoration, specifically, be the sander bistrique that a kind of nog plate is done straight reciprocating motion.
Background technology
The bistrique of existing sander, its nog plate generally all rotates under the drive of power transmission shaft.This grinding wheel head structure is fairly simple, but can't polish for the corner of operation surface, and its job area is restricted.Because nog plate rotates, can stayed the circle trace in addition by on the surface of polishing.
Summary of the invention
The technical problem that the utility model solves is exactly that existing sander bistrique is restricted at the job area of operation surface, and can stayed the problem of circle trace on the surface of polishing.
Sander translation bistrique described in the utility model comprises grinding head cover, is arranged on the main nog plate in the grinding head cover, comprises also being arranged on main disk on the grinding head cover, that be connected with power transmission shaft that main disk joins by a linkage and main nog plate; This linkage comprises the axle that is connected on the main nog plate, be connected the main disk radially axle of certain position and the connecting rod that becomes to be rotationally connected with this diaxon respectively, and the main disk of rotation drives main nog plate by this linkage and does straight reciprocating motion.
In order to improve operating efficiency, as to improvement of the present utility model, in grinding head cover, also be provided with secondary disk and secondary nog plate, secondary disk rotates under the drive of main disk; Secondary disk joins by another linkage and secondary nog plate; This another linkage comprises the axle that is connected on the secondary nog plate, be connected secondary disk diameter to the axle of certain position and the connecting rod that becomes to be rotationally connected with this diaxon respectively, and the secondary disk of rotation drives secondary nog plate by another linkage and does straight reciprocating motion.
In order to prevent that nog plate from resting on motionless and grinding head cover motion on the surface of being polished, as further improvement, main disk, secondary disk are that a gearratio is 1 the gear that is meshed; The axle on the main nog plate, the axle on the main disk and with the axle on the main nog plate, the connecting rod that is connected of axle on the main disk respectively with the axle on the secondary nog plate, the axle on the secondary disk and with at the axle on the secondary nog plate, a connecting rod that is connected on secondary disk about the perpendicular bisector symmetry of the main disk center of circle and secondary circle disk center line.
When using the utility model, generally speaking, direction and master that sander translation bistrique moves on operation surface, the direction of motion of secondary nog plate is perpendicular, because it is main, secondary nog plate has certain distance (these relative two edges can not contact yet) between the relative two edges at a distance of recently the time, if it is main, relative two edges and the master of secondary nog plate, the direction of motion of secondary nog plate is perpendicular, promptly main, the two edges that secondary nog plate is relative are parallel with the direction that sander translation bistrique moves on operation surface, will lead, zone line on the operation surface between the relative two edges of secondary nog plate can not polished.In order to prevent that this situation from taking place, as further improving of the present utility model, the relative two edges of described major and minor nog plate parallel, the direction of motion out of plumb of described edge and major and minor nog plate again.
In order in polishing, to be sucked away by abrasive dust, dust under polishing, for any sander translation bistrique recited above, on grinding head cover, be connected with sweep-up pipe, this sweep-up pipe communicates with the inner chamber of grinding head cover.General sander all has dust absorption fan, and dust absorption fan can be extracted out through sweep-up pipe dust in grinding head cover.In addition, the power transmission shaft of general sander all adopts flexible axle, and this flexible axle interted in sweep-up pipe, entered grinding head cover, drives the nog plate motion.
In order to make major and minor nog plate moving linearly more reliable, it is more flexible to move, and for any sander translation bistrique recited above, is provided with chute in the inboard of grinding head cover, the dual-side of major and minor nog plate extend in the chute, and major and minor nog plate does reciprocating linear motion along chute.The dual-side that is preferably in major and minor nog plate is provided with the pulley that can rotate with respect to major and minor nog plate, and the flange of pulley extend in the described chute.
The beneficial effects of the utility model: 1, changed the sander bistrique, a kind of bistrique of nog plate translation of no operatton restriction is provided in the deficiency that the job area of operation surface is restricted; 2, owing to the nog plate translation, this utility model can not stay the circle trace on the surface of being polished; 3, the nog plate of existing sander bistrique is to rotate, and nog plate moving linearly of the present utility model is broken through traditional concept.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the upward view of Fig. 1;
Fig. 3 is the A-A cutaway view among Fig. 2;
