Description

Technical Field

[0001] The present invention relates to a multi-adaptable, low-cost, and efficient assembly tool and method for wing-shaped rings, and more specifically, to the use of the multi-adaptable tool to achieve pinned assembly of wing-shaped rings of this type. This relates to the field of mechanical processing. Background Art

[0002] Multi-adaptability refers to the ability to adapt to this type of wing ring or similar structural features. Currently, most aerodynamic wings often use this type of wing ring to lock the wings after folding and unfolding. At the same time, the assembly requirements of this type of wing ring structure and the gap between it and the product it is assembled with are very high.

[0003] In the traditional assembly method for wing-shaped rings, a trial fit is first performed between the ring and the product to which it is attached. To ensure clearance between the ring and the product, copper foil is inserted between the parts to the required clearance specifications as specified in the drawings. 502 glue is then used to secure the parts and pressed down firmly by hand to ensure a tight fit until the 502 glue is fully cured. The ring is then bonded to the product to be assembled. After bonding, all 502 glue on the ring and other parts is removed. This method results in a long assembly cycle, and the acetone used to remove the glue is a hazardous chemical, harmful to the human body and flammable, making assembly time-consuming and labor-intensive.

[0004] In order to reduce production difficulty, save manpower and improve assembly efficiency, it is necessary to design reasonable assembly tooling and innovate a multi-adaptive assembly tooling and method to achieve low cost and high efficiency of pin-jointed assembly of this type of special ring structure of the wing. Summary of the Invention

[0007] During operation, the process lock pin 6 is inserted from the bottom of the through hole 51 of the wing root, so that the upper end of the process lock pin 6 extends out from the upper end of the through hole 51 of the wing root, and the middle hole 41 of the copper sheet and the bottom center hole 31 of the elastic wing special ring are inserted into the upper end of the process lock pin 6 in sequence, and the upper locking screw 2 is screwed into the upper threaded hole 61 of the process lock pin 6. The upper locking screw 2 presses the copper sheet 4 and the elastic wing special ring 3 on the upper surface of the through hole 51 of the wing root; the lower locking screw 8 is inserted from the through hole 51 of the wing root The bottom of the hole 51 is screwed into the lower threaded hole 62 of the process locking pin 6; then the wing-shaped ring 3 is clamped at the bottom of the folding wing 1, and the upper locking screw 2 is inserted into the positioning hole 11 of the folding wing, and the shaft tube 9 is inserted into the axial hole 12 of the folding wing and the axial hole 52 of the wing root, and the drilling machine is used to match the pin holes of the folding wing 1 and the wing-shaped ring 3 along the position of the positioning pin hole 32 of the wing-shaped ring, and the matched pin holes of the folding wing 1 and the wing-shaped ring 3 are connected with pins.

[0008] The upper end of the process locking pin 6 is in a truncated cone shape, and an annular boss is provided on the outer wall of the process locking pin 6 below the truncated cone shape.

[0009] There is a gasket 7 between the lower locking screw 8 and the lower end surface of the process locking pin 6.

[0010] The process locking pin 6, the upper locking screw 2, and the lower locking screw 8 are all made of 45# carbon structural steel and are blackened.

[0011] The assembly method using the above-mentioned multi-adaptable low-cost and high-efficiency assembly tool for the special-shaped ring of the wing is characterized by comprising the following steps:

[0012] Step 1: First, align the through hole 51 of the wing root, the middle hole 41 of the copper sheet, and the bottom center hole 31 of the wing special ring.

DETAILED DESCRIPTION

[0048] The technical solution for the multi-applicable wing shaped ring assembly tool is as follows:

[0049] A process lock pin is used to locate the position of the wing-shaped ring. The head size of the process lock pin and the wing-shaped ring adopt a taper fit to limit multiple degrees of freedom. At the same time, a threaded hole is machined on the top and bottom of the process lock pin.

[0050] An upper locking screw is used to fix the special ring of the wing and the copper sheet, with a cross groove on one end and a thread on the other end.

[0051] A lower locking screw is used for axial tightening of the tooling, with a slot on one end and a thread on the other end.

[0052] A copper sheet, which is a standard copper sheet within the required range of design indicators, has a through hole in its center.

[0053] A washer is used to increase the contact area of ​​the lower locking screw and has a cylindrical structure with a through hole in the center.

[0054] The low-cost and efficient assembly method of the wing special ring is as follows:

[0055] Step 1: First, align the holes of the folding wing 1, the holes of the copper sheet, and the holes of the wing special ring within the design index requirements. The gap occupied by the thickness of the copper sheet is used to ensure the clearance between the folding wing 1 and the wing special ring for subsequent overall assembly. Then, insert the process lock pin 6 into the aligned holes of the folding wing 1, copper sheet, and wing special ring;

[0056] Step 2: Align the wing-shaped ring along the heading direction, screw the upper locking screw into the threaded hole of the process lock pin head, fix the wing-shaped ring to the copper sheet, install the wing root 5, and install the shaft tube 9 into the hole between the folding wing 1 and the wing root 5;

[0057] Step 3: Use the locking screw and a washer to screw into the threaded hole at the bottom of the process lock pin and tighten it axially until the copper skin fits tightly.

[0058] Step 4: Use a drilling machine to drill the pin holes used to connect the wing root 5 and the special ring of the wing.

[0059] Step 5: Remove the lower locking screw and a gasket; take out the wing root 5; remove the upper locking screw and copper sheet; take out the process locking pin.

[0060] Step 6: Use pins to fix the wing special ring to the wing root 5, and the product assembly is completed.

[0061] Example:

[0062] In order to make the technical means, method and process of the present invention easy to understand, the present invention is further described below in conjunction with the specific parts assembly. Figures 1 to 11 .

[0063] The final assembly technical requirements for the product are that the gap between the wing-shaped ring 3 and the wing root 5 should be 0.1-0.2mm, and the wing-shaped ring 3 should be equipped with punch pins to be assembled on the folding wing 1. The specific assembly process is as follows:

[0064] Step 1: First, align the holes in the wing root 5, the 0.15mm copper sheet 4, and the wing shaped ring 3. The gap occupied by the thickness of the 0.15mm copper sheet 4 ensures the clearance between the wing root 5 and the wing shaped ring 3 during subsequent assembly. Then, insert the process locking pin 6 into the aligned holes in the wing root 5, 0.15mm copper sheet 4, and wing shaped ring 3.

[0065] Step 2: Align the wing-shaped ring 3 along the heading direction, screw the upper locking screw 2 into the threaded hole of the process lock pin head, fix the wing-shaped ring 3 and the 0.15mm copper sheet 4, install the folding wing 1, and install the shaft tube 9 and insert it into the hole between the wing root 5 and the folding wing 1;

[0066] Step 3: Use the lower locking screw 8 and a gasket 7 to screw into the threaded hole at the bottom of the process locking pin 6 and tighten it axially until the 0.15mm copper sheet 4 fits tightly.

[0067] Step 4: Use a drill press to punch the pin holes used to connect the folding wing 5 and the special ring 3 of the wing.

[0068] Step 5: Remove the lower locking screw 8 and a gasket 7; take out the shaft tube 9; remove the upper locking screw 2 and 0.15mm copper sheet 4; take out the process locking pin 6.

[0069] Step 6: Use pins to fix the special ring 3 of the wing to the folding wing 5. The product assembly is completed.

[0070] The above details the main features, specific implementations and advantages of the present invention. It should be noted that those skilled in the art may make several improvements and variations based on the technical principles of the present invention, but such improvements and variations should also be considered within the scope of protection of the present invention.
