Description
Technical field
The present invention relates to the manufacture of intelligent machine equipment and production field, more specifically a kind of efficient footwear
Bottom/vamp special grinding manipulator.
Background technology
In traditional shoemaking production field, sole is typically all to carry out bonding life by special chemical glue with vamp
Production, and sole or vamp are required for carrying out glue before bonding or handle the spraying of water, and in order to improve bonding effect, production
Required in process first to being polished at the sprayed glues of sole or vamp, because if sole or vamp are excessively smooth, meeting
The bonding effect of glue is influenceed, after polishing, its surface is more suitable for the bonding of glue.Traditional grinding apparatus is all directly with carrying
The sander of bistrique directly carries out grinding process to sole or vamp, traditional grinding apparatus exist much using upper deficiency and
Shortcoming, wherein, its grinding angle and polishing dynamics are not easy to control, and the polishing experience with technical work carries out control hand-manipulated entirely
System, and the grinding head of equipment is all that the bistriques of whole group all angles is used in combination, traditional grinding apparatus be easy to because
Lack for control dynamics and using the control of angle, cause the too fast loss of grinding head of some angle, and the polishing of other angles
Head is also without loss so that technical staff must not be changed without the grinding head of whole group, cause the raising of production cost.
The content of the invention
Disclosed by the invention is a kind of efficient sole/vamp special grinding manipulator, and its main purpose is to overcome existing
There are technology above shortcomings and shortcoming there is provided a kind of mechanical hand of special article of footwear automatically grinding, it not only can be automatic
Ground carries out polishing operation to sole or vamp, automatic to realize to the control dynamics of grinding head, grinding angle and polishing scope
Effectively control, realizes its adjust automatically, automatically grinding and the purpose automatically controlled, and can make the grinding head of all angles
In polishing in use, stress evenly, is lost more impartial, it is to avoid the situation for the grinding head excessive loss of a certain angle occur goes out
It is existing, the service efficiency and service life of grinding head are improved, production cost is reduced.
The technical solution adopted by the present invention is as follows:
A kind of efficient sole/vamp special grinding manipulator, including one be used to polishing the mechanical arm of sole, one be arranged on the machine
