Abstract
The invention discloses a new stone cutting machine device free from a contact coil spring. One carbon brush holder bonding pad is punched on the original position on which a coil spring is installed by the punching piece of a carbon brush rack under the condition that an inner hole and the function of the inner hole are not affected, and the joint of a spindle outgoing line, which is originally provided with the coil spring, is provided with another spindle bonding pad. When the new stone cutting machine device free from the contact coil spring is installed, firstly a spindle is put into an enclosure, then the spindle outgoing line penetrates out of the enclosure via a hole which is not provided with the carbon brush rack, and therefore, the two bonding pads are welded into a whole by butt weld or other welding modes out of the enclosure. At the time, the carbon brush holder is installed to finish a task. The coil spring is omitted, the performance is improved while the cost is lowered, and the new stone cutting machine device free from the contact coil spring is easy to popularize.
Description
Affiliated technical field
The present invention relates to a kind of electric tool makita 4100NH, the makita 4100NH new equipment of especially contactless wind spring.
Background technology
At present, the way of contact between known makita 4100NH spindle coil and the carbon brush holder uses wind spring to be enclosed within the recess that dashes part or real copper of carbon brush holder usually, and is pretty troublesome during installation.Because the inner problems such as sand and dust or oxidation that get into of use cutting machine, wind spring ruptures through regular meeting, causes problems such as loose contact, makes troubles to work.
Summary of the invention
It is a kind of without wind spring that the present invention provides, and contact good new method between the spindle coil that makes makita 4100NH and the carbon brush holder.
The present invention provides the concrete technical scheme of new method to be: carbon brush holder dash part under endoporus and the impregnable situation of other function; On the position of original installation wind spring, go out a carbon brush holder bonding pad; Originally the joint of installing the spindle lead-out wire wind spring is provided with an other spindle bonding pad, puts into casing to spindle earlier during installation, passes the spindle lead-out wire through the hole that carbon brush holder is not installed the outside of casing again; Like this; Article two, bonding pad is one through the weldering of butt-joint or other welding manner outside casing, and at this moment carbon brush holder is installed again, finishes the work.
The invention has the beneficial effects as follows: save wind spring at machine, can also improve performance when reducing cost.

The specific embodiment
Carbon brush holder (1) is under endoporus and the impregnable situation of other function; Going out a carbon brush holder bonding pad (2) on the position of original installation wind spring; Originally the joint of installing spindle lead-out wire (3) wind spring is provided with an other spindle bonding pad (4), puts into casing to spindle earlier during installation, passes spindle lead-out wire (4) through the hole that carbon brush holder (1) is not installed the outside of casing again; Like this; Carbon brush holder bonding pad (2) is one through butt-joint or the weldering of other welding manner with spindle bonding pad (4) outside casing, carbon brush holder (1) at this moment is installed again, the task completion.
Claims (3)
1. the makita 4100NH new equipment of a contactless wind spring comprises: carbon brush holder, carbon brush holder bonding pad, spindle lead-out wire and spindle bonding pad is characterized in that: a carbon brush holder bonding pad is gone out at the position of installing carbon brush holder originally wind spring.
2. the makita 4100NH new equipment of a kind of contactless wind spring according to claim 1, it is characterized in that: the position of installing the spindle lead-out wire originally wind spring is provided with a spindle bonding pad.
3. the makita 4100NH new equipment of a kind of contactless wind spring according to claim 1 is characterized in that: be one to carbon brush holder bonding pad and spindle bonding pad through butt-joint or the weldering of other welding manner.
