A kind of glass circular hole beveller
Technical field
The invention belongs to glass working machine, particularly relate to a kind of glass circular hole beveller.
Background technology
In prior art, mechanical being similar to that is applied to glass circular hole chamfering shaken wall type bench drill, and the conical grinding wheel of bench drill has respective angles, for example 30 °, 45 °, shakes wall the position-limit mechanism of controlling the grinding wheel feed degree of depth is set.
The above-mentioned wall type glass circular hole beveller tool that shakes requires general small-bore glass circular hole to deal with for technical standard except process velocity is slow, but can not adapt to the particularly chamfer machining of larger aperture glass circular hole of the glass circular hole of having relatively high expectations for chamfering precision uniformity and grinding face fineness, main cause is that bistrique exists and inevitably swings and degree of depth position-limit mechanism owes reliable.
Summary of the invention
Technical problem to be solved by this invention is to solve the existing wall type glass circular hole beveller tool that shakes to have the technical problem that process velocity is slow, precision is low and uniformity is poor and grinding face fineness is poor and a kind of glass circular hole beveller is provided.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of glass circular hole beveller, comprise frame 1, positioning ball screw 2, conical grinding wheel 5, motor 7 and positioner, it is characterized in that: the dead ahead of described positioner in described conical grinding wheel 5; Described positioning ball screw 2 is horizontally fixed in described frame 1, on described positioning ball screw 2, be provided with the feeding adjusting handle 2-1 that regulates described motor 7 positions, the described positioning ball screw 2 straight-line slide plates in left and right are fixed described motor 7, described motor 7 force-output shafts are fixedly equipped with described conical grinding wheel 5, described frame 1 has installed vertical table-board 3, and described vertical table-board 3 is provided with the hole that described motor 7 force-output shafts pass and the workpiece holder 4 centered by described motor force-output shaft is fixedly housed.
Further, described positioner comprises left elevating lever 8, right elevating lever 9, upper location-plate 10, lower location-plate 11 and lifting nut 12, described left elevating lever 8, right elevating lever 9 are provided with screw thread, and described upper location-plate 10, lower location-plate 11 are loaded on left elevating lever 8, right elevating lever 9 by described lifting nut 12 and the assembling of described upper location-plate 10, lower location-plate 11 screw threads; Described vertical table-board 3 peripheries are provided with baffle plate 6; Described baffle plate 6 is made for transparent material.
The invention has the beneficial effects as follows: conical grinding wheel of the present invention is directly fixed on motor force-output shaft, and motor support is in having accurate, the stable positioning ball screw of micro-feeding, under the cooperation of level table and workpiece holder, this beveler can overcome and existingly shakes that wall type glass circular hole beveller tool bistrique swings and degree of depth position-limit mechanism is owed reliable defect, make particularly high, the high conformity of the chamfering precision of large aperture circular hole and the upper and lower Kong Bian of circular hole of glass circular hole chamfering, grinding face fineness also better simultaneously, process velocity also obviously improves.That the present invention has is simple to operate, the outstanding advantages of low cost of manufacture.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
In accompanying drawing, the list of parts of each label representative is as follows:
1, frame, 2, positioning ball screw, 2-1, feeding adjusting handle, 3, vertical table-board, 4, workpiece holder, 5, conical grinding wheel, 6, baffle plate, 7, motor, 8, left elevating lever, 9, right elevating lever, 10, upper mounted plate, 11, bottom plate, 12, lifting nut.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, a kind of glass circular hole beveller, comprises frame 1, positioning ball screw 2, conical grinding wheel 5, motor 7 and positioner, it is characterized in that: the dead ahead of described positioner in described conical grinding wheel 5; Described positioning ball screw 2 is horizontally fixed in described frame 1, described positioning ball screw 2 is equipped with feeding adjusting handle 2-1, by adjusting handle 2-1, regulate the front and back position of motor 7, the described positioning ball screw 2 straight-line slide plates in left and right are fixed described motor 7, described motor 7 force-output shafts are fixedly equipped with described conical grinding wheel 5, described frame 1 is supported with vertical table-board 3, and described vertical table-board 3 is provided with hole and the workpiece holder 4 centered by described motor 7 force-output shafts that described motor 7 force-output shafts pass.Described vertical table-board 3 peripheries are provided with baffle plate 6, in order to prevent that glass abrasive dust night from splashing, at vertical table-board 3 peripheries, are provided with baffle plate 6, and baffle plate 6 is made for transparent material, is convenient to from the visual observation condition of production.
Described positioner comprises left elevating lever 8, right elevating lever 9, upper location-plate 10, lower location-plate 11 and lifting nut 12, described left elevating lever 8, right elevating lever 9 is provided with screw thread, described upper location-plate 10, lower location-plate 11 is by described lifting nut 12 and described upper location-plate 10, the assembling of lower location-plate 11 screw threads is loaded on left elevating lever 8, on right elevating lever 9, during chamfering, glass pieces is in upper location-plate 10, location between lower location-plate 11, positioner is for fixing glass workpiece, the position of assurance glass pieces in process do not invented and changed to guarantee machining accuracy, by regulating lifting nut 12 can regulate upper location-plate 10, the glass pieces that spacing between lower location-plate 11 is processed different size.
The method of operating of this glass circular hole beveller is: according to glass circular hole diameter and depth of chamfering requirement, by the feeding adjusting handle 2-1 of positioning ball screw 2, adjust the height on conical grinding wheel 5 relative workpiece holder 4 surfaces, the circular hole of glass pieces is placed on the conical grinding wheel of High Rotation Speed and rely on positioner complete circular hole to and chamfering, when glass pieces contacts completely with workpiece holder 4 surfaces, chamfering finishes.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
