Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
Refer to Fig. 1, Fig. 1 is the overall structure diagram of the first specific embodiment provided by the present invention.
In the first specific embodiment provided by the present invention, the deflection measurement device of slide-like saw mainly includes
Mounting rod 2, bow pen 3, data board 4 and mounting seat 8.
Wherein, mounting rod 2 is mainly used in installing bow pen 3 and remaining parts, and it is arranged on the upper cunning of slide-like saw
On seat 1 (slide-like saw typically has upper lower slider), and it is connected with the side wall of upper saddle 1.For reasonable utilization space, typically
Mounting rod 2 can be arranged on the right side wall of upper saddle 1, certain mounting rod 2 can also be arranged on upper saddle 1 remaining any one
On the wall of surface side.
Bow pen 3 is arranged on mounting rod 2, is mainly used in the synchronous deflection rail rule, record saw when saw runs
Mark.And in order to rule conveniently, the tail end of bow pen 3 can be fixed on mounting rod 2, and the nib of head end vacated, be easy to
Data board 4 is in close contact.Upper saddle 1 in normal sawing, can move along straight line in theory (actually motion when meeting
Ceaselessly to both sides deflection), sawing piece also synchronous linear motion when high-speed rotation of centre, and the rotation of this sawing piece
Plane is exactly the theoretical sawing plane of upper saddle 1.Be arranged such it is ensured that the actual motion state of upper saddle 1 without distortion
It is delivered on bow pen 3, make bow pen 3 and upper saddle 1 synchronize motion.
As shown in Fig. 2 Fig. 2 is the concrete structure schematic diagram of data board shown in Fig. 1.
Data board 4 is arranged in mounting seat 8, is primarily used for the part for bow pen 3 drawing, in order to ensure track of painting
Accuracy, be typically fixedly connected with mounting seat 8.Data board 4 typically all has drawing surface and the back side, and this drawing surface
Be in close contact with the nib of bow pen 3, in addition this drawing surface also need to perpendicular to the theoretical sawing plane of upper saddle 1 due to
Operationally, upper saddle 1 theoretically moves along a straight line slide-like saw, and the saw blade being provided with is while linear motion
Also high-speed rotation, and the Plane of rotation of this saw blade is exactly the theoretical sawing plane of upper saddle 1 so in slide-like saw
When operation deflection, the nib synchronous motion simultaneously deflection of bow pen 3, and the deflection of this nib is also in a level
Carry out in face.Therefore data board 4 drawing surface perpendicular to upper saddle 1 theoretical sawing plane it is ensured that the pen of bow pen 3
Point is freely painted thereon, without interruption, the accuracy of the track that do not affect finally to paint and reliability.
Herein preferably, data board 4 is rectangular, and its length direction is parallel to the sawing motion direction of upper saddle 1.By
In slide-like saw operationally in theory along straight cuts, the shape of therefore data board 4 is arranged such can be complied with well
The ruuning situation of slide-like saw.Certainly, data board 4 is not limited only to a kind of this shape of rectangle, as long as ensureing its drawing
The area on surface is sufficiently large.
Additionally, according to the investigation of the practical operation situation to slide-like saw, its operation curve in zero load is to compare
Regular, straight, and after running a period of time, in the case of load, the operation curve of slide-like saw is then opened
Begin that deflection occurs, and due to factors such as positive feedbacks, its deflection will be gradually increased.If so using overall rectangular note
Record plate 4 recording the track of slide-like saw, then it is possible that the incomplete situation of pictorial image.Pin is in this regard, the present embodiment
It is provided with side wing 401 in the both sides of data board 4, similar to the wing of aircraft, and the presence due to side wing 401, increased
The transverse width of data board 4.And, the width of this side wing 401 is gradually increased also as the motion of upper saddle 1.I.e. in peace
After having filled side wing 401, the overall transverse width of data board 4 is gradually increased along the direction of motion of upper saddle 1.So set
Put so that slide-like saw is with the presence of load, and in the case that deflection is increasing, data board 4 remains able to completely
The running orbit curve record of slide-like saw is got off by ground.
In addition, for the deflection trajectory diagram of precise quantification slide-like saw, the present embodiment also on data board 4 along
Its length direction, is provided with centrage 402 in centre position.This centrage 402 can be identified for that out the theoretical sawing fortune of upper saddle 1
Dynamic rail mark, i.e. straight line.Then, it is equally along its length, be also provided with longitudinal scale 403 in its both sides.Due to vertical
To the presence of scale 403 it becomes possible to quantify the transversal displacement of slide-like saw deflection track；Additionally, the width along data board 4
Degree direction, also in its thicker end, (due to the presence of side wing 401, therefore on data board 4, entirety occurs in that thicker end to the present embodiment
And narrow end) it is provided with horizontal scale 404.Because the presence of horizontal scale 404 is it becomes possible to quantify slide-like saw deflection track
Vertical misalignment amount.
In sum, the deflection measurement device of the slide-like saw that the present embodiment is provided, installs line by mounting rod 2
Pen 3, fixes data board 4 by mounting seat 8, then supplies bow pen 3 to record saw running orbit by data board 4, and by record
Vertical relation between the drawing surface of plate 4 and the theoretical sawing plane of upper saddle 1 is ensureing the track being recorded on data board 4
Accurately undistorted.Therefore, the deflection measurement device of the slide-like saw that the present embodiment is provided, can detect in real time and record
The deflection track of downslide A seating saw, makes technical staff grasp the running status of slide-like saw in real time, and makes corresponding operating,
Be conducive to improving the total quality of product.
The present embodiment also provides a kind of slide-like saw, including fuselage and the deflection measurement device being arranged on fuselage, its
