Description
Technical field
The utility model relates to piano processing machinery fields, specifically clamp tail apparatus of the piano around string machine.
Background technique
It include spindle box and boot around string machine, the existing clamp tail mechanism around string machine is mainly bent steel wire using set axis
The mode (as shown in Figure 1) of clamping, the method for this clamping steel wire is around string process: manually hanging over steel wire bending around string
In tail case on hanging scroll, interior hanging scroll is tensed backward by cylinder, so that interior hanging scroll is entered housing axis, utilizes the taper of housing axis inner wall
With the cooperation between interior hanging scroll, the steel wire for hanging over interior hanging scroll will be clamped between interior outer shaft, and steel wire passes through gas after the completion of string
Dynamic cutting steel wire.Existing clamping steel wire mode has following technical disadvantages: (1), this clamping mode can waste one section and hang over
Steel wire on interior hanging scroll；(2), when cutting steel wire, steel wire is since in tensioned state is tensed, cutting can make steel wire have one suddenly
Reaction force, steel wire can beat pop-up, be easy to be bound to worker；(3), since paino wire is a kind of harder special steel
Material, using gas cutting steel wire, scissors quick abrasion will often replace scissors；(4), interior outer shaft is due to the easy mill of the friction of steel wire
Damage, needs to be replaced frequently interior outer shaft, and maintenance cost and frequency are high.
Utility model content
For the technical problems in the prior art, the purpose of this utility model is: providing a kind of piano around string machine
Clamp tail apparatus.The clamping and release of steel wire are realized by the folding of clamping pliers, it is only necessary to one end of clamping steel wire, compared to
The clamping mode of sleeve shaft-type can be effectively saved steel wire and without gas cutting.
In order to achieve the above object, the utility model adopts the following technical solution:
Piano is around the clamp tail apparatus of string machine, and correspondence is mounted at string tail case, including clamping pliers, clamping pliers are mounted on
Boot one end corresponding with spindle box end, the jaw sides of clamping pliers is towards spindle box；When clamping pliers are in clamped condition, folder
Tight steel wire；When clamping pliers are in releasing orientation, steel wire is unclamped.After this structure, steel wire is placed on to the jaw of clamping pliers
Place, the folding of manual control or machine automatization control clamping pliers, makes clamping pliers are in clamped condition can clamp by pressing force
