Description

Technical Field

[0001] This invention relates to the field of submachine gun sight assembly technology, and in particular to a device and method for assembling a submachine gun sight mount component. Background Technology

[0002] Currently, to improve the ease of assembly of the aiming mechanism, the submachine gun's rear sight, rear sight shaft, and rear sight mount need to be pre-assembled into a single rear sight mount component using a retaining ring.

[0003] The submachine gun sight base assembly is currently done by hand. Due to the complexity of the structure, steel balls need to be installed in different positions, all of which are related to the mounting shaft of the sight. During the assembly process, the steel balls are very easy to slip out of the holes, making the assembly process unworkable. This brings great difficulties and burdens to the assembly workers. Because the assembly method is difficult to master, the assembly efficiency of the gun is not high. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device and method for assembling the sight mount component of a submachine gun, which can realize the convenient and quick assembly of the sight mount component of the submachine gun.

[0005] The objective of this invention is achieved as follows:

[0006] A device for assembling a submachine gun sight mount component includes a base, a positioning pin, a limiting block, and a handle. The base is L-shaped, with the upper surface of the flat section of the base used to fit against the bottom plane of the sight mount for positioning. The upper end of the vertical section of the base has a positioning pin hole along the longitudinal direction. One end of the positioning pin is fitted into the positioning pin hole, and the other end of the positioning pin is used to pass through the sight hole of the rear sight for positioning. The side of the base has a T-shaped groove along the longitudinal direction, and the limiting block is slidably fitted into the T-shaped groove for positioning. The limiting block is used to limit the steel ball in the positioning hole of the rear sight shaft of the sight mount. A handle limiting groove is provided in the middle of the bottom of the T-shaped groove. The handle limiting groove is a strip-shaped groove extending along the T-shaped groove. The handle is perpendicular to the limiting block and is fitted onto the limiting block. One end of the handle passes through the limiting block and engages with the handle limiting groove, which limits the travel of the handle.

[0007] Preferably, the outer surface of the positioning pin is stepped shaft-shaped, and the outer surface of the positioning pin is provided with a guide section, a positioning section, and a positioning pin assembly section in sequence from thin to coarse. The guide section is conical and is used for guiding. The positioning section is cylindrical and is used for positioning in conjunction with the aiming hole of the scale. The positioning pin assembly section is cylindrical and is used for interference fit with the positioning pin hole on the base.

[0008] Preferably, one end of the limiting block is provided with a notch for the ruler shaft clearance, the notch is used to clearance the ruler shaft, and the thickness of the limiting block at the notch corresponding to the ruler shaft clearance is less than the radius of the steel ball II in the ruler shaft positioning hole.

[0009] Preferably, the outer surface of the handle is stepped shaft-shaped, and the outer surface of the handle is provided with a handle assembly section and an operating section from thin to coarse. The handle assembly section is cylindrical, and the limiting block is provided with a handle hole. The handle assembly section passes through the handle hole and is interference-fitted with the handle hole. The operating section is cylindrical and is used for hand operation, driving the limiting block to slide.

[0010] A method for assembling a submachine gun sight mount component.

[0011] First, install the scale spring and steel ball one into the scale positioning hole of the sight base in sequence; then place the scale positioning groove on the steel ball one, press down the scale, and align the scale rotation thread hole with the center of the large positioning hole and the small positioning hole of the sight base.

[0012] Then, position the bottom plane of the sight mount on the positioning surface of the base, and simultaneously position the positioning pin through the aiming hole of the sight scale.

[0013] Next, install the scale shaft spring and steel ball two into the scale shaft positioning hole of the sight seat. Then, press down on steel ball two and push the handle into place so that the limit block presses against the upper limit of steel ball two.

[0014] Next, pass the dial indicator shaft through the large positioning hole on one side of the sight base, rotate the dial indicator shaft, pass it through the dial indicator rotary thread hole, and then pass it through the small positioning hole on the other side of the sight base until the positioning surface of the dial indicator shaft contacts the dial indicator shaft clearance notch of the limit block.

[0015] Then, push the handle in the opposite direction until it is in place. The two parts of the steel ball pop out and are limited by the positioning surface of the dial indicator shaft. Continue to rotate the dial indicator shaft until the positioning surface of the dial indicator shaft contacts the side of the sight base.

[0016] Finally, the retaining ring is inserted into the positioning ring groove of the scale shaft to complete the assembly of the sight mount component.

[0017] Due to the adoption of the above technical solution, the present invention has the following beneficial effects:

[0018] In this invention, the locating pin of the assembly tool can position and constrain the sight scale of the rear sight mount component, and the limiting block of the assembly tool can limit the steel ball within the locating hole of the sight scale shaft. The new assembly method for the submachine gun rear sight mount component is characterized by simple and practical tools and convenient and quick assembly operations. The assembly method involved in this invention has great promotion and practical value in firearm assembly, and its widespread application will generate good economic and social benefits.

Detailed Implementation

[0035] The invention will be further described below with reference to the accompanying drawings.

[0036] See Figures 7-13 The sight mount component is a single unit consisting of the sight mount 5, the scale spring 6, the steel ball, the scale 8, the scale shaft 9, the scale shaft spring 10, and the retaining ring 11. The scale spring 6 is a cylindrical spring; the steel ball is a sphere; the scale 8 has an L-shaped structure, with the diameter of the aiming hole 801 being larger than the diameter of the positioning section 202 of the positioning pin 2; the cylindrical shaft diameter 902 of the scale shaft 9 mates with the positioning large hole 503 of the sight mount, the stud shaft diameter 903 mates with the rotary threaded hole 803 of the scale, the cylindrical shaft diameter 904 mates with the positioning small hole 504 of the sight mount, and the positioning ring groove 905 mates with the inner diameter of the retaining ring 11; the scale shaft spring 10 is a cylindrical spring; the retaining ring 11 is a shaft retaining ring installed in the positioning ring groove 905 of the scale shaft 9, limiting the positioning of the scale shaft 9 on the sight mount 5.

[0037] See Figures 1-12 A device for mounting a sight mount component of a submachine gun.

[0038] The device consists of a base 1, a positioning pin 2, a limiting block 3, and a handle 4. The base 1 is L-shaped, with a positioning pin hole 101 on the upper part and a T-shaped groove 102 on the side for sliding of the limiting block. A handle limiting groove 103 is provided in the middle of the T-shaped groove for limiting the handle 4, thereby limiting the limiting block 3. The handle limiting groove 103 is a strip-shaped groove that limits the stroke of the handle 4.

[0039] The outer surface of the positioning pin 2 is stepped shaft-shaped. The outer surface of the positioning pin 2 is provided with a guide section 201, a positioning section 202, and a positioning pin assembly section 203 in sequence from thin to coarse. The guide section 201 is conical and is used to guide the positioning pin 1 through the scale aiming hole 801. The positioning section 202 is cylindrical and is used for positioning the scale 8. The positioning pin assembly section 203 is cylindrical and is used for installing the positioning pin 2, and is interference-fitted with the positioning pin hole 101 of the base.

[0040] The limiting block 3 is a cuboid with a rectangular cross-section. The guide rail 301 mates with the T-shaped groove 102 of the base and slides along the T-shaped groove 102. A handle hole 302 is provided in the middle, and a notch 303 for the dial indicator shaft clearance is provided on the plane. The handle hole 302 is used to install the handle 4, and the notch 303 for the dial indicator shaft clearance is used to clearance when installing the dial indicator shaft 9. This can prevent the steel ball 2 from disengaging from the dial indicator shaft positioning hole 502 of the sight seat after the limiting block 3 is moved, thus preventing the dial indicator shaft 9 from being unable to rotate into place.

[0041] The outer surface of the handle 4 is stepped shaft-shaped. The outer surface of the handle 4 is provided with a handle assembly section 401 and an operation section 402 from thin to coarse. The handle assembly section 401 is cylindrical and is used for the installation of the handle 4. It is interference-fitted with the handle hole 302 of the limiting block 3. The operation section 402 is cylindrical and is used for sliding the limiting block 3.

[0043] First, insert the scale spring 6 and steel ball 7a into the scale positioning hole 501 of the sight base 5 in sequence; then place the positioning groove 802 of the scale 8 on the steel ball 7a, and press down on the scale 8 so that the scale rotation threaded hole 803 is basically aligned with the center of the large positioning hole 503 and the small positioning hole 504 of the sight base, see... Figure 14a ;

[0044] Then, place the bottom plane 505 of the sight mount on the positioning surface 104 of the base, and simultaneously make the positioning pin 2 pass through the aiming hole 801 of the sight scale. Figure 14b ;

[0045] Next, insert the scale shaft spring 10 and steel ball 7b into the scale shaft positioning hole 502 of the sight base 5; then, press down on the steel ball 7b and push the handle 4 into place (at this time, the handle 4 is limited by the handle limiting groove 103 of the base), so that the limiting block 3 presses down on the steel ball 7b in the scale shaft positioning hole 502 of the sight base 5, see Figure 14c ;

[0046] Next, the scale shaft 9 is passed through the large positioning hole 503 on one side of the sight seat 5. The scale shaft 9 is rotated, passing through the scale rotation threaded hole 803, and then through the small positioning hole 504 on the other side of the sight seat, until the positioning surface 901 of the scale shaft 9 contacts the scale shaft clearance notch 303 of the limit block 3. At this time, the steel ball 7b is pressed down by the limit block 3. Figure 14d ;

[0047] Then, push the handle 4 in the opposite direction until it is in place (at this time, the handle 4 is restricted by the other side of the handle limiting groove 103 of the base), and the steel ball 7b pops out a small part (the bottom wall thickness of the notch 303 of the scale shaft, and the steel ball 7b is limited by the positioning surface 901 of the scale shaft, so it is not enough to pop out), continue to rotate the scale shaft 9 until the positioning surface 901 of the scale shaft contacts the side 506 of the sight base, see Figure 14e ;

[0048] Finally, the retaining ring 11 is secured in the positioning ring groove 905 of the scale shaft, see... Figure 14f Remove the rear sight mount assembly; the finished product is shown below. Figure 14g .
