Description
Technical field
The present invention relates to pianos to process auxiliary tool, specifically, is related to qin circle stationary fixture.
Background technology
The manufacture craft of the qin circle of prior art grand piano is：It is squeezed with backrest part and gets togather whole qin in workpiece not holding any government official post outer ring
It encloses, after the spray coating operations for completing whole qin circle, grinding and buffing work is carried out to each position, after completion entirety covers with paint, lacquer, colour wash, etc. work, then
Soundboard and sympathetic response disk are assembled in backrest.
In qin circle sanding process, present technique is the qin loop-shaped according to different model, and corresponding fixed bottom plate is configured,
Bottom plate is fixed on numerical control sander, then is fixed on bottom plate across backrest gap by a screw locking fixture, coordinates number
Control machine run trace carries out sanding.
The prior art has the disadvantage that：1. the qin circle of different model is processed in sanding, need to dismantle the bottom plate on board,
Mating bottom plate is replaced, i.e. bottom plate, fixture, qin circle corresponds, and versatility is poor；2. increasing replacing construction, increase and add
Work complexity；3. the new process of pair qin circle processing, i.e., the technique that other parts are first installed in backrest, the nothing in sanding process
Method is fixed again with prior art using screw locking fixture across backrest.
Invention content
For the technical problems in the prior art, the purpose of the present invention is：It provides a kind of simple in structure, versatile
Qin circle stationary fixture.
In order to achieve the above object, the present invention adopts the following technical scheme that：
Qin circle stationary fixture, positions qin circle, including：The bottom plate of support qin circle carries out qin circle the positioning of clamping
Block is matched for clamping tightly the self-locking cylinder of qin circle with locating piece, and the magnetic hole with the cooperation of numerical control sander is hung for sling bottom plate
Hanging component；The location hole of the different qin ring number of multigroup correspondence is set on bottom plate, and locating piece and self-locking cylinder are fixed by location hole
On bottom plate, magnetic hole and suspending assembly are arranged on bottom plate.
As a preferred embodiment, qin circle includes outer ring and the backrest being arranged in outer ring, backrest includes crossbeam and vertical beam, backrest
Rear end be flank；Crossbeam extends in outer ring along left and right directions, and vertical beam extends to the inside of flank on rear side of crossbeam.
As a preferred embodiment, locating piece includes：To the lateral register block for controlling inside and carrying out clamping positioning of outer ring, with oneself
Lock cylinder cooperation, the clamping and positioning block to being clamped positioning on rear side of crossbeam.
As a preferred embodiment, locating piece is mounted on by screw in location hole.
As a preferred embodiment, the quantity of self-locking cylinder is three, and the left side that crossbeam is held out against with locating piece cooperation, one
The right of crossbeam, an inside for withstanding on flank are held out against with locating piece cooperation.
As a preferred embodiment, the circumference of bottom plate is corresponding to outer ring profile, magnetic hole is located at the middle part of bottom plate.
As a preferred embodiment, suspending assembly includes three hoisting rings, three hoisting rings are arranged in triangle on bottom plate.
As a preferred embodiment, qin circle stationary fixture, erecting for vacancy position between filling Qin Quan bottoms and bottom plate is further included
Block；Bottom plate erects block mounting hole equipped with the different qin ring number of multigroup correspondence, erects block and is fixed on by erecting block mounting hole
On pedestal.
It is erected in block mounting hole as a preferred embodiment, erecting block and being mounted on by screw.
As a preferred embodiment, the quantity for erecting block is multigroup, corresponding different qin ring number；The quantity of locating piece to be multigroup,
Corresponding different qin ring number.
Generally speaking, the invention has the advantages that：
1. clamping mode does not use the mode across backrest, but the side that locating piece and self-locking cylinder is used to be matched for clamping tightly
Formula fixes qin circle, simple in structure, applied widely, the technique for being also applied for first installing other parts in backrest.
Using corresponding detachable locating piece, 2. self-locking cylinder can be coordinated, qin circle is carried out according to the qin circle of different model
It is fixed.Therefore without being reconfigured the bottom plate of different model, the cost of manufacture of polylith bottom plate is reduced, eliminates and repeatedly replaces bottom plate
Time, versatility greatly increases.
3. due to the use of self-locking cylinder, qin circle is placed on bottom plate corresponding position, and after need to only connecting tracheae, twisting is opened
It closes, three cylinders can be controlled to push up outward simultaneously, after fixed qin circle, dismantle tracheae, whole sanding out of shape, compared to previous Screw clamp
Hand-operated clamping greatly reduces the operating time.
4. it is not a plane because there is part qin circle entirety bottom surface, it is corresponding on bottom plate to place qin circle whole machine balancing
Position setting erects block to erect overhead positions, convenient for following process.
5. in order to which bottom plate is easy for installation, three hoisting rings are set, to facilitate lifting bottom plate.
Description of the drawings
Fig. 1 is the structure diagram that qin circle stationary fixture clamps qin circle.
Wherein, 1 is bottom plate, and 2 be hoisting ring, and 3 be magnetic hole, and 4 be locating piece, and 5 be location hole, and 6 is erect block, and 7 be certainly
Lock cylinder, 8 be crossbeam, and 9 be vertical beam, and 10 be flank.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Qin circle stationary fixture including bottom plate, locating piece, self-locking cylinder, magnetic hole, suspending assembly, erects block.
Qin circle includes outer ring and the backrest being arranged in outer ring, and backrest includes crossbeam and vertical beam, and the rear end of backrest is flank；
Crossbeam extends in outer ring along left and right directions, and vertical beam extends to the inside of flank on rear side of crossbeam.
The circumference of bottom plate is corresponding to outer ring profile, and to global shape specification, approximately one piece of bottom is configured in a kind of qin circle
Plate.Bottom plate is equipped with the location hole of multigroup installation locating piece, and each group location hole corresponds to different qin ring number.Bottom plate is equipped with more
The corresponding different qin ring number of group erect block mounting hole, and each group erects block mounting hole and corresponds to different qin ring number.Locating piece and
Self-locking cylinder is fixed on by location hole on bottom plate, is erected block and is fixed on pedestal by erecting block mounting hole.
Locating piece includes carrying out the lateral register block of clamping positioning to the left and right inside of outer ring and match with self-locking cylinder
It closes, the clamping and positioning block to being clamped positioning on rear side of crossbeam.The quantity of locating piece is multigroup, corresponding different qin ring number.
The quantity of self-locking cylinder is three, and the left side that crossbeam is held out against with locating piece cooperation, one coordinates with locating piece
The right of crossbeam is held out against, an inside for withstanding on flank is achieved in 3 points of lockings.Three self-locking cylinders connect same group of gas supply dress
It puts, therefore can realize that synchronous stretch out holds out against.
Magnetic hole is located at the middle part of bottom plate, coordinates with numerical control sander, and cooperation track is out of shape and rotates.
