Abstract

The utility model relates to a glass edge grinding machine, composed of grinding head components, a guide rail, a working table, a working table spindle, a main motor, and a water disc. Four grinding head components are used; the spindle bearing of the working table adopts a single-row tapered roller bearing; the position of the guide rail is higher than the position of the water disc. Accordingly, the grinding speed is increased; the shaking and the creeping phenomena of the working table are eliminated; the production efficiency and the grinding quality are improved; the operation performance of the glass edge grinding machine is improved.

Description

Glass edge grinder

The utility model relates to the plant equipment on grinding work piece inclined-plane, says so exactly to relate to glass edge-grinding machine.

Existing glass edge-grinding machine mainly is made of grinding head assembly, guide rail, workbench, workbench main shaft, main motor, water pond, and its course of work is that main motor rotates workbench by workbench main shaft; Grinding head assembly moves to suitable position by guide rail the glass that is placed on the workbench is carried out grinding; Water pond is used for reclaiming the glass powder that cooling water and grinding glass process produce.Accompanying drawing 1a and accompanying drawing 1b are existing glass edge-grinding machine concrete structure schematic diagrames, wherein accompanying drawing 1a is a front view, accompanying drawing 1b is a vertical view, as shown in the figure, main motor 8 rotates workbench main shaft 3 by driving a pair of belt pulley and a pair of gear, rotate thereby drive workbench 2, wherein workbench main shaft bearing 4 is single-row radial ball bearings; Three grinding head assemblies 1 are fixed together with upper bed 12, base 9, following lathe bed 10, guide rail 11 are fixed together, the parts that grinding head assembly 1 and upper bed 12 constitute can be fit to the position glass that is placed on the workbench 2 is carried out grinding moving on the guide rail 11, glass is placed on the anchor clamps 5 on the workbench 2, vacuumizes by vacuum tube 7 it is fixed; The position of water pond 6 is higher than guide rail 11.

There is following shortcoming in existing glass edge-grinding machine:

(1) owing to adopt three grinding head assemblies 1, makes that each bistrique grinding sendout is big, cause grinding speed on the low side, be about 1.5 meters/minute, influenced production efficiency and grinding quality;

(2) workbench main shaft 3 adopts single-row radial ball bearing 4, analyze from this shaft strength, ring mainly bears axial force in it, and this class bearing mainly is used for bearing radial force, can not bear big axial force, thereby after using a period of time, interior ring roller weares and teares gradually, and the gap increases gradually, and it is not steady to cause spindle operation to have some setbacks, make workbench 2 runnings that jitter phenomenon be arranged, cause the grinding glass quality to descend;

(3) because guide rail 11 positions are lower than water pond 6, make the cooling water water clock that contains glass powder on the water pond 6 on guide rail 11, guide rail 11 just seriously gets rusty in use for some time, causes upper bed 12 to move difficulty, is difficult to that grinding head assembly 1 is moved to suitable position glass is carried out grinding.

The purpose of this utility model is existing glass edge-grinding machine is improved: (1) adopts four grinding head assemblies, makes grinding speed be increased to 3 meters/minute, thereby enhances productivity and grinding quality; (2) workbench main shaft is used single-row tapered roller bearing instead, bear axial force by bearing spider, make the wearing and tearing of bearing inner ring and roller drop to minimum level, the end play of main shaft and bearing is also adjusted easily, thereby eliminate the play phenomenon of main shaft, the glass face that grinds no longer includes mechanical chatter mark, reaches the purpose that improves the grinding glass quality; (3) guide rail 11 installation sites are higher than water pond, make cooling water be difficult for being splashed on the guide rail, thereby for ease of maintenaince maintain guide rail.

The utility model compared with prior art has following advantage:

(1) grinding speed is higher, thereby has improved production efficiency;

(2) workbench main shaft is used single-row tapered roller bearing instead, has avoided the main shaft play, and the workbench running is steady, thereby has improved grinding quality;

(3) the guide rail installation site is higher than water pond, for ease of maintenaince maintenance.

Accompanying drawing 2a and accompanying drawing 2b are the structural representations of the utility model glass edge-grinding machine, accompanying drawing 2a is a front view, and accompanying drawing 2b is a vertical view, as shown in the figure, glass edge-grinding machine after the improvement and prior art operation principle are basic identical, and improvements are that the utility model adopts four grinding head assemblies 1; The a pair of diameter pulley that main motor 8 drives changes 90 millimeters and 350 millimeters into; Workbench main shaft bearing 4 is used single-row tapered roller bearing 13 instead; Guide rail 11 installation sites are higher than water pond 6.

Embodiment

With the glass edge-grinding machine grinding radius of structure shown in accompanying drawing 2a, accompanying drawing 2b is the inclined-plane of 400 millimeters glass.It is on 400 millimeters the circumference that anchor clamps on the workbench 25 and four grinding head assemblies 1 are moved to radius, glass is placed on the anchor clamps 5, start vavuum pump, grinding head assembly and main motor can carry out grinding, to be ground finishing, close vavuum pump, take off glass, the glass surface fineness 3.2 after the grinding does not have obvious grinding lines, guide rail does not have rusty stain when using 2 years, the workbench running steadily.

The comparative example

Use the glass edge-grinding machine of structure shown in accompanying drawing 1a, accompanying drawing 2b, the glass of grinding and operating process are with above-mentioned implementation column, and gained glass surface fineness is 6.3, and obvious grinding lines is arranged, and guide rail seriously gets rusty workbench galloping when using four months.

Claims

A kind of glass edge-grinding machine that is made of grinding head assembly, guide rail, workbench, workbench main shaft, main motor, water pond is characterized in that adopting four grinding head assemblies, and the workbench main shaft bearing is a single-row tapered roller bearing, and guide rail position is higher than water pond.
