Specific embodiment
Below in conjunction with the accompanying drawings chair leg frame processing method in helicopter operation person's seat of the present invention is described in further details.
As shown in Fig. 1 to Fig. 5, in helicopter operation person's seat of the present invention, chair leg frame processing method can include following step
Suddenly：
Step S101：It is the profile for processing left chair leg 11 and right chair leg 12.Further, it is that left and right chair leg blank is pacified
It is mounted in CNC milling machine, the outline that left chair leg 11 and right chair leg 12 are processed by CNC milling machine.Also, process outline
Left chair leg 11 and the bottom surface of right chair leg 12 leave predetermined margin, predetermined margin is generally according to needing to be chosen as 0.2mm～2.0mm
Between, can specifically take 0.5mm.Certainly, in addition in CNC milling machine, other suitable processing methods can also be used.
Step S102：The above-mentioned left chair leg 11 for processing outline is symmetrically fixedly connected with right chair leg 12, left and right is formed
Chair leg molectron, and the right flank of left chair leg 11 contacted with the left surface of right chair leg 12.Further, it is possible in 11 He of left chair leg
12 corresponding position of right chair leg processes two step grooves respectively and (is respectively arranged with two in left chair leg 11 and right chair leg 12
Two step grooves on step groove, and left chair leg 11 are corresponding with the position of two step grooves in left chair leg 12).Its
In, using accurate processing, aperture is 28mm (+0.13/+0.1) to step groove.Straight pin 3 is set in step groove again, by left chair
Lower limb 11 and right chair leg 12 are fixed, and form left and right chair leg molectron, straight pin 3 a diameter of 28mm (+0.08/+0.05).Its
In, the position of two step grooves can be arranged as required in multiple suitable positions, in order that fixed more firm, left chair leg
Two step grooves in 11 (or right chair legs 12) are in distribution up and down (on the basis of the view direction of Fig. 2).
Further, in above-mentioned steps S102, also include the clamping plate 4 thick by 2mm～3mm and bolt by the left and right chair
Lower limb molectron is fixed；Wherein, clamping plate 4 is located at the right flank of 11 left surface of left chair leg and right chair leg 12 respectively, by left chair leg
11 and right chair leg 12 constitute left and right chair leg molectron gripped.
Step S103：Processed from the side of left and right chair leg molectron simultaneously all solid in left chair leg 11 and right chair leg 12
Determine through hole and waist type stepped hole.It is also possible to be processed by multiple suitable processing methods, in the present embodiment, it is to pass through
Sleeping boring machine is processed to left and right chair leg molectron.
It should be noted that in left chair leg 11 and right chair leg 12 in addition to above-mentioned fixed via and waist type stepped hole, also
Can be by other holes, by the boring machine that crouches in the case of being in equally left and right chair leg molectron in left chair leg 11 and right chair leg 12
To be processed.Due to the quantity in other holes more, but be all to be integrally machined by combining form, a therefore no longer string
Lift.
Step S104, the left and right chair leg molectron after machining in above-mentioned steps S103 are separated, and are machined
Left chair leg 11 and right chair leg 12.
Step S105, processes the fix bar matched with the fixed via in left chair leg 11 and right chair leg 12, then by solid
The left chair leg 11 for machining and right chair leg 12 are fixed by fixed pole, to form chair leg frame.In step S103, the fixation for obtaining is processed
Through hole in the present embodiment, can preferably at least include four, the fix bar matched with aforementioned four fixed via including multiple
Including 22, thick connecting rod 21 of a support beam and two thin connecting rods 23, concrete structure is referred to prior art in Fig. 1
Structure, here is omitted.
The chair leg frame processing method of the present invention, left chair leg 11 is combined in the way of the chair leg molectron of left and right with right chair leg 12
Together, it is processed on milling machine and sleeping boring, part processing precision is not required to very high, completes part processing, just reachable after assembling
Arrive good result.In addition, chair leg frame processing method of the present invention, positions reliability during processing, required tool part is few, frock manufacture letter
Single, easy to operate during use.Further, not high to operator's skill set requirements, ensure that quality, part passing rate of processing
Height, improves production efficiency, has saved production cost.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, on the premise of original without departing from the present invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
