Description
Technical field
The present invention relates to spiral rigid locking bullet bottom gap technology fields, and in particular to a kind of control spiral rigid locking
The process of rifle clearance between charge and bottom of shell.
Background technology
Dagger pistol, revolver or runner rifle are all made of spiral rigid locking device and are latched both at home and abroad at present, rifle
Branch locking after require latch surfaces and play bottom surface between gap it is necessary≤0.13mm, if clearance between charge and bottom of shell cannot be guaranteed 0.13mm with
Under, it is breakdown that it will cause primers, to influence the normal work of firearms.Since there are many size for influencing clearance between charge and bottom of shell,
Cumulative limit is very big, and in the prior art, the main process for being measured clearance between charge and bottom of shell again using first mechanical processing locking recess is added
After work locking recess, locking limiting device is will appear when blocking device screws in emitter and has been caught in locking recess and bullet
Bottom gap is but>The phenomenon that 0.13mm, spiral starting point, lead of screw and the spiral that two male parts are unable to control during precession are long
Degree.Therefore, clearance between charge and bottom of shell cannot be guaranteed using the processing method of first milling locking recess completely, after the part after processing flows into assembly
It needs to ensure clearance between charge and bottom of shell by apolegamy, labor intensity is big, and efficiency is low.
Invention content
The purpose of the present invention is first processing the process measured afterwards for use in the prior art, it can not ensure firearms bullet
Bottom gap has that labor intensity is big again by the method for apolegamy to ensure clearance between charge and bottom of shell, and the low problem of efficiency provides a kind of control
The process of spiral rigid locking rifle clearance between charge and bottom of shell, this method change technique process, using first measurement post-processing
Technology pattern ensure that clearance between charge and bottom of shell all meets product design requirement, without being matched in assembling technology procedure.
To achieve the above object, the technical solution adopted in the present invention is as follows：
The process for controlling spiral rigid locking rifle clearance between charge and bottom of shell, includes the following steps：
Step 1 obtains：Obtain the gun and bullet type gauge using spiral rigid locking；
Step 2 measures：Bullet type gauge is put into emitter first, turn blocking device is until the faces blocking device A contradict
Bullet type gauge bottom surface, until turn blocking device can not be continued, measure the faces blocking device A between bullet type gauge bottom surface at a distance from；
Step 3 makes marks：It makes marks in the place that blocking device is aligned with locking limiting device；
Step 4, processing locking recess：Blocking device is screwed off, in the place processing locking recess marked；
Step 5 matches clearance between charge and bottom of shell：It is surveyed according to the physical location of locking limiting device and locking recess, then with bullet type gauge
Clearance between charge and bottom of shell is measured, locking recess is modified.
Preferably, in the measurement process of the step 2, blocking device is socketed in by spiral on emitter, and drive is closed
Locking device A is moved forward, until contradicting bullet type gauge bottom surface, clearance between charge and bottom of shell is zero at this time, meets product design requirement.Pass through
First measure clearance between charge and bottom of shell, it is ensured that clearance between charge and bottom of shell is in 0.13mm hereinafter, reprocessing locking recess, is avoided that size ring in process
The problem of spiral starting point is unable to control in more and latching process.
Preferably, it makes marks in such a way that groove or painting are red in the step 3.Processing is solved with simple and practical method
Positioning.
Preferably, the processing method of the step 4 uses Milling Process, the width of locking recess to require basis in product figure
Upper reserved margin controls the tolerance of processing locking recess with this.Milling Process precision is high, and the tolerance of card slot can be protected reliably
Card, it is ensured that at the quality of rifle.
Preferably, locking recess is modified with pincers worker in the step 5.Card slot after Milling Process is deburred,
Overlap etc. is handled, the accuracy of manufacture is improved, ensures that locking limiting device and locking recess limit are reliable.
Beneficial effects of the present invention：
By using the process for first measuring post-processing, first bullet type gauge is used to measure, ensures clearance between charge and bottom of shell, then make marks
The mode of milling locking recess locks clearance between charge and bottom of shell, break it is traditional first process the process measured afterwards, make clearance between charge and bottom of shell
It is formed directly by reprocessing guarantee after measuring qualification, without being matched in assembling process, improves the assembly of finished product rifle
Quality reduces labor intensity, improves efficiency of assembling.

Specific implementation mode
With reference to embodiment and attached drawing, invention is further described in detail.
As shown in Figure 1 to Figure 2, a kind of process of control spiral rigid locking rifle clearance between charge and bottom of shell, includes the following steps：
Step 1 obtains：Obtain the gun and bullet type gauge 3 using spiral rigid locking；
Step 2 measures：Bullet type gauge 3 is put into emitter 6 first, turn blocking device 1 is until the faces blocking device A 2
3 bottom surface of bullet type gauge is contradicted, until turn blocking device 1 can not be continued, is measured between the faces blocking device A 2 and 3 bottom surface of bullet type gauge
Distance；Blocking device 1 is socketed in by spiral on emitter 6, and the faces blocking device A 2 is driven to travel forward, until contradicting bullet
3 bottom surface of type gauge, clearance between charge and bottom of shell is zero at this time, meets product design requirement.In the present embodiment, clearance between charge and bottom of shell must Man Zu≤
The requirement of 0.13mm.
Step 3 makes marks：It makes marks in the place that blocking device 1 is aligned with locking limiting device 4；Using groove or painting
Red mode makes marks, and is not limited only with both modes in the present invention certainly, and other modes can also be used to do
Label.
Step 4, processing locking recess：Blocking device 1 is screwed off, in the place processing locking recess 5 marked；At this
It is processed using milling in embodiment, (reserved margin can for reserved margin on the basis of product figure requires for the width of locking recess 5
It is calculated with basis and moves axially 0.13mm, is converted to the rotation of spiral circumference and grow) public affairs for processing locking recess 5 are controlled with this
Difference, Milling Process precision is high, and the tolerance of card slot can reliably be ensured, it is ensured that at the quality of rifle, before ensureing machining accuracy
It puts, other processing methods can also be used to process locking recess.
Step 5 matches clearance between charge and bottom of shell：According to the physical location of locking limiting device 4 and locking recess 5, then with bullet type gauge 3
Clearance between charge and bottom of shell is measured, locking recess 5 is modified.Locking recess 5 is modified with pincers worker in the present embodiment, ensures to close
Lock limiting device 4 limits reliably with locking recess 5.Burr, overlap processing are carried out to card slot, improve the accuracy of manufacture.
Using the process for first measuring post-processing, solve by mechanical processing it cannot be guaranteed that the technology of fitted position is difficult
Then topic is directly reprocessed by measuring clearance between charge and bottom of shell, ensure that clearance between charge and bottom of shell all meets product design requirement, without assembling
It is matched in the process, improves the assembling quality of finished product rifle, reduce labor intensity, improve efficiency of assembling.
