Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, and in particular to processing fixtures for tail wing structure parts of air-to-air missiles. Background Technology

[0002] Air-to-air missile tail wing structure components typically include the main wing structure, connecting and transmission parts, and auxiliary and functional parts. When machining these parts, clamping fixtures, such as flat-jaw pliers, are required. These pliers can be used to clamp the wing blanks. By adjusting the position of the jaws and the clamping force, the blanks are fixed on the machine tool table for cutting, milling, and other machining operations.

[0003] Most existing clamping fixtures use fixed clamps. As the number of uses increases, the clamps will wear out. If it is inconvenient to disassemble and replace them, the worn clamps will cause inaccurate positioning of the wing structure parts, resulting in the dimensional accuracy and form and position tolerances of the machined parts exceeding the tolerances. This will affect the assembly accuracy of the wing and other missile components. Furthermore, when the size and shape of the wing structure parts change due to design improvements, the clamps that are inconvenient to disassemble and replace are difficult to adjust and adapt, which will cause mismatch in the clamping of parts and make it impossible to guarantee the machining accuracy.

[0004] Therefore, most of the existing clamping fixtures use fixed fixtures. If the fixtures are worn and difficult to disassemble and replace, it will lead to inaccurate positioning of the wing structure parts. Furthermore, when the wing structure parts change, it will cause mismatch in the clamping of the parts. All of these factors will make it impossible to guarantee the machining accuracy. It is possible to design a machining fixture for the tail wing structure parts of air-to-air missiles, using detachable and replaceable fixtures to improve the machining accuracy of the parts. Utility Model Content

A second threaded rod 209 is vertically inserted through the inner side of the strip groove 208 of the mounting block 207, and a square threaded sleeve 211 is sleeved on the outside of the second threaded rod 209. A first insertion post 212 is installed on one side of the square threaded sleeve 211. 7. An upper clamp template 213 is provided on the side away from the rectangular telescopic column 201. The upper clamp template 213 is provided with a first insertion hole 214 corresponding to the first insertion column 212 on the side near the mounting block 207. A lower clamp template 215 is provided below the mounting block 207. Multiple sets of second insertion columns 216 are longitudinally spaced at one edge of the upper end of the lower clamp template 215. A second insertion hole 217 is provided below the mounting block 207 corresponding to the second insertion columns 216. An operating table 102 is installed in the middle of the upper end of the base plate 1. The parts are placed on the operating table 102. A rectangular slide groove 101 is provided around the upper part of the base plate 1, which is located outside the operating table 102. The rectangular slide groove 101 facilitates the movement and adjustment of the clamp.

[0023] Please see Figures 3-5 In this embodiment, a rectangular telescopic column 201 is fitted with a rectangular telescopic sleeve 202. A cylinder 203 is installed at the upper end of the rectangular telescopic column 201. Driven by the cylinder 203, the rectangular telescopic column 201 moves along the rectangular telescopic sleeve 202 to a suitable height. A rectangular threaded sleeve 204 is installed at the lower end of the rectangular telescopic sleeve 202. A first threaded rod 205 passes through the middle of the rectangular threaded sleeve 204, so that the rectangular threaded sleeve 204 drives the rectangular telescopic sleeve 202 to move along the rectangular slide groove 101 to a suitable position. A first motor 206 is installed at one end of the first threaded rod 205. The first threaded rod 205 is set along the rectangular slide groove 101. Driven by the first motor 206, the first threaded rod 205 rotates. A second motor 210 is installed at the upper end of the second threaded rod 209. Driven by the second motor 210, the second threaded rod 209 rotates.

[0024] When working, first place the part on the operating table 102. Then, according to the shape characteristics of the part, select the required upper clamp template 213 and lower clamp template 215. Then, the upper clamp template 213 is positioned and connected to the square threaded sleeve 211 through the first insertion hole 214 along the first insertion post 212. Finally, the second insertion post 216 drives the lower clamp template 215 to be positioned and connected to the mounting block 207 through the second insertion hole 217, and it can then be used.

[0025] Depending on the placement of the part, driven by cylinder 203, the rectangular telescopic column 201 moves along the rectangular telescopic sleeve 202 to a suitable height. Then, driven by the first motor 206, the first threaded rod 205 rotates, causing the rectangular threaded sleeve 204 to drive the rectangular telescopic sleeve 202 to move along the rectangular slide groove 101 to a suitable position. Through continuous lifting and moving, the edge of the part is positioned between the upper clamping template 213 and the lower clamping template 215. Then, driven by the second motor 210, the second threaded rod 209 rotates, causing the square threaded sleeve 211 to drive the upper clamping template 213 to move downward along the strip slide groove 208, cooperating with the lower clamping template 215 to fix and clamp the part. After the clamp has been used for a period of time, it can be disassembled for inspection or replacement.

[0026] After placing the parts through the above steps, select the required fixture template according to their shape characteristics for replacement and assembly. Then, the clamping assembly is adjusted and firmly clamped according to the placement position of the parts, thus facilitating the processing of the parts. By using detachable and replaceable fixtures, operators can quickly disassemble the current fixture and replace it with a suitable fixture according to different processing tasks, without the need for long-term adjustment or re-clamping. This enables rapid switching of processing tasks, significantly improving production efficiency. Furthermore, it allows for timely replacement with fixtures of qualified precision, avoiding quality problems such as dimensional deviations and out-of-tolerance form and position of airfoil parts caused by the use of fixtures with poor precision. This ensures that each part meets the high-precision processing requirements, solving the problem that most existing clamping fixtures use fixed fixtures. If the fixtures are worn and inconvenient to disassemble and replace, it will lead to inaccurate positioning of airfoil parts, and when the airfoil parts change, it will cause mismatch in the clamping of the parts. All of these problems will make it impossible to guarantee the processing accuracy.
