Abstract
The invention discloses a method for replacing a pin roll of an external adjustment sheet. The method comprises the following specific steps: step 1, clamping the external adjustment sheet with a to-be-replaced pin roll onto a clamp, drilling off a locking pin by use of a drill bit, and taking out the pin roll with abrasion exceeding standards from the bracket; step 2, clearing an inner cavity of a mounting hole in a bracket; step 3, measuring the diameter of the mounting hole in the bracket; step 4, processing out a locking hole with a corresponding size in the pin roll; step 5, placing the processed pin roll into the mounting hole of the bracket, and aligning the locking hole in the pin roll to the locking hole in the bracket; step 6, selecting the corresponding locking pin, cooling the locking pin for 15-10 minutes in liquid-state nitrogen, then, pressing the locking pin into the locking holes of the bracket and the pin roll, and locking the pin roll on the bracket; and step 7, locking a combined part of the locking pin and the bracket. By replacing the pin roll without damaging a component main body, a using function of the component can be recovered, so that the repair problem of the external adjustment sheet is solved, scrapping of the external adjustment sheet is avoided, and the repair cost is reduced.
Description
Technical field:
The present invention relates to technical field of engine overhaul, be specifically related to a kind of method that bearing pin changed by outer adjustment sheet.
Background technology:
The outer adjustment sheet of spout is the extension of fuselage, ensures seamlessly transitting of fuselage and jet pipe, time uniform stream flow through afterbody, reduce airplane tail group resistance.The structure of outer adjustment sheet as shown in Figure 1, Figure 2, Figure 3 shows, outer adjustment sheet 4 rear end is provided with support 3, bearing pin 2 is sleeved in the installing hole on support 3, and bearing pin 2 is locked on support 3 by locking pin 1, outer adjustment sheet is by the up and down adjustment that realize self of rear end bearing pin in the installing hole of support, due to the deviation from circular from of nozzle exit, bearing pin is is very easily worn and torn in installing hole, causes part rejection.Normal manufacturing process reinstalls outer adjustment sheet after locking pin and bearing pin are fitted into support.But finished product needs to destroy outer adjustment sheet as repaired according to process for making, and cost is too high, and repairing is worth little.
Summary of the invention:
The object of this invention is to provide a kind of method that bearing pin changed by outer adjustment sheet, the replacing that part main body just realizes wearing and tearing bearing pin can not be destroyed.
For achieving the above object, the present invention is by the following technical solutions:
The method of bearing pin changed by a kind of outer adjustment sheet provided by the invention, and concrete steps are as follows:
Step 1, by the outer adjustment sheet clamping of bearing pin to be replaced on fixture, fix the support of outer adjustment sheet rear end, adjustment drill bit, the locking hole center on alignment support, removes locking pin by bit drills, takes out from the installing hole of support the bearing pin wearing and tearing and exceed standard;
Step 2, the installing hole inner chamber on support to be cleaned out;
The diameter of installing hole on step 3, measurement support;
Step 4, choose the bearing pin of correspondingly-sized according to measurement result, simultaneously according to the size of locking hole on support, bearing pin process the locking hole of correspondingly-sized, and get rid of limit, locking hole hole on bearing pin burr and to locking hole sharp edge rounding;
Step 5, the bearing pin that processes in step 4 to be loaded in the installing hole of support, and adjust the locking hole on bearing pin and the locking hole on support aligns;
Step 6, according to the corresponding locking pin of locking hole selection of dimension, cool locking pin 15-10 minute in liquid nitrogen after, be pressed in the locking hole of support and bearing pin, make lock clasp on support;
Step 7, the junction of locking pin and support to be locked.
Adopt punching pin and compressed air to the installing hole inner chamber cleaning on support in described step 2.
The locking hole that drill bit and reamer drill and ream out on bearing pin on drilling machine is used in described step 4.
In shown step 6, rear for cooling locking pin is pressed in the locking hole of support and bearing pin by use hammer and plug.
Beat punching point with the junction of punching pin at locking pin and support or adopt the locking of " ball closing in " method with plug in described step 7.
Described drill bit drilling speed is 300 ~ 500r/min, and the amount of feeding is 0.056 ~ 0.16mm/r.
Beneficial effect of the present invention: change the using function that bearing pin can recover part by not destroying part main body, effectively can solve the problem that in part, damaged parts is changed, repairing for part provides economy, efficiently method, be applied in the processing of part, implementation result is fine, both solved the reparation problem of outer adjustment sheet, and avoided scrapping of outer adjustment sheet, reduce repair cost.

Detailed description of the invention:
Below in conjunction with embodiment, the present invention is described in further detail.
The method of bearing pin changed by a kind of outer adjustment sheet of the present invention, and concrete steps are as follows:
Step 1, by the outer adjustment sheet clamping of bearing pin to be replaced on fixture, fix the support of outer adjustment sheet rear end, adjustment drill bit, the locking hole center on alignment support, removes locking pin by bit drills, takes out from the installing hole of support the bearing pin wearing and tearing and exceed standard;
Installing hole inner chamber on support is cleaned out by step 2, employing punching pin and compressed air;
The diameter of installing hole on step 3, measurement support;
Step 4, choose the bearing pin of correspondingly-sized according to measurement result, simultaneously according to the size of locking hole on support, bearing pin uses drill bit and reamer to drill and ream out on drilling machine the locking hole of correspondingly-sized on bearing pin, and get rid of limit, locking hole hole on bearing pin burr and to locking hole sharp edge rounding;
Step 5, the bearing pin that processes in step 4 to be loaded in the installing hole of support, and adjust the locking hole on bearing pin and the locking hole on support aligns;
Step 6, according to the corresponding locking pin of locking hole selection of dimension, be pressed in the locking hole of support and bearing pin, by lock clasp on support with hammer and plug cool locking pin 15-10 minute in liquid nitrogen after;
Step 7, to beat punching point with punching pin in the junction of locking pin and support or adopt " ball closings in " method to lock with plug;
Step 8, inspection
The mated condition of visual examination bearing pin and support, under the prerequisite do not moved axially, allows slight swing and angle to move, and checks assembling place, checks the junction of locking pin and support, do not allowed crackle with magnifying glass (10 times).
