The utility model discloses a kind of combined grinding head of grinding of automatic bevelling, including connecting rod and bistrique, the bistrique includes the unit bistrique of at least two different sand number, the unit bistrique segmentation is connected in turn in same connecting rod, boundary slot is equipped between every section, the boundary well width is 0.2mm, and entire grinding head coaxiality is in positive and negative 0.01mm；The unit bistrique outer wall is equipped with several grooves, arranged in parallel between each groove, and the spacing between the groove is 2.5mm, groove inner width is 0.4mm, gash depth is 0.8mm, and trench wall is circular arc chamfering with bottom surface junction, and the radius of the circular arc chamfering is 0.45mm；The bistrique top is additionally provided with a round inner concave, and the depth of the circle inner concave is 0.1mm；The utility model can complete to reduce the bistrique replacement frequency when processing while automatic bevelling, improve production efficiency and stability.
Description
Technical field
The utility model belongs to the combination mill of optical crystal chip and glass processing field of tool more particularly to a kind of automatic bevelling
Head.
Background technology
Universal with large-size smartphone and tablet computer, touch screen has gradually penetrated into each angle of our lives
It falls.Touch-screen applications are increasingly extensive, also improved to touched panel glass processing dimension requirement on machining accuracy, shape be tradition
Profiling edging machine is impossible, imitates the numerical control formation glass edge-grinding machine of numerical control metal incision machine just in widely used, this skill
The key that can art be promoted the use of is critical component therein --- subminiature electroplating diamond grinding apparatus --- use of bistrique
Performance and used life.In the prior art, it in product processing fluting, bevelling or plain grinding, needs to use two generally for product
Kind or two or more sand bistriques, but it is replaced as frequently as bistrique, production efficiency can be seriously affected, and stablize to production
Property has a great impact；And in existing bistrique, function is excessively single, and each bevelling needs to use special edge-falled machine,
It is inconvenient.
Invention content
To solve the above-mentioned problems, the utility model provides a kind of combined grinding head of grinding of automatic bevelling, can complete to fall automatically
Bistrique replacement frequency when processing is reduced while side, improves production efficiency and stability.
It adopts the following technical scheme that thus：A kind of combined grinding head of grinding of automatic bevelling, including connecting rod and bistrique, feature
It is：The bistrique includes the unit bistrique of at least two different sand number, and the unit bistrique segmentation is connected to same company in turn
Boundary slot is equipped on extension bar, between every section, the boundary well width is 0.2mm, and entire grinding head coaxiality is in positive and negative 0.01mm；Institute
The unit bistrique outer wall stated is equipped with several grooves, arranged in parallel between each groove, and the spacing between the groove is 2.5mm, ditch
Slot inner width is 0.4mm, gash depth 0.8mm, and trench wall and bottom surface junction are circular arc chamfering, the half of the circular arc chamfering
Diameter is 0.45mm；The bistrique top is additionally provided with a round inner concave, and the depth of the circle inner concave is 0.1mm.
Further, the sand number of the unit bistrique is 300#, 500# or 800#.
When work, bistrique sand number to be used can be needed according to product, bistrique is combined successively, changed to solve frequency
Influence of the bistrique to product reduces the time that product is wasted because replacing bistrique in process, and improves because frequently replacing
Bistrique processes unstability caused by product；And the automatic bevelling bistrique in unit bistrique can be according to the groove pair on bistrique
Product carries out direct bevelling, reduces manufacturing procedure.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Fig. 2 is the side view of the utility model.
Specific implementation mode
Referring to attached drawing.The present embodiment is a kind of combined grinding head of grinding of automatic bevelling, including connecting rod 1 and bistrique 2, the bistrique
Including two unit bistriques, unit bistrique sand number is 300# and 800#, and the unit bistrique segmentation is connected to same connection in turn
Boundary slot 3 is equipped on bar, between every section, the boundary well width is 0.2mm, and entire grinding head coaxiality is in positive and negative 0.01mm；Institute
The unit bistrique outer wall stated is equipped with several grooves 4, arranged in parallel between each groove, and the spacing between the groove is 2.5mm, ditch
Slot inner width is 0.4mm, gash depth 0.8mm, and trench wall and bottom surface junction are circular arc chamfering, the half of the circular arc chamfering
Diameter is 0.45mm；The bistrique top is additionally provided with a round inner concave, and the depth of the circle inner concave is 0.1mm.
Claims (2)
