Description
Technical Field
[0001] The embodiments of the present application relate to the field of fixture technology, and in particular to a fixture for aviation aluminum alloy parts that can adapt to different specifications. Background Art
[0002] An alloy based on aluminum with a certain amount of other alloying elements added is one of the light metal materials. In addition to the general characteristics of aluminum, aluminum alloys also have some specific characteristics of alloys due to the different types and quantities of alloying elements added. The density of aluminum alloys is high, the specific strength is close to that of high alloy steel, and the specific stiffness exceeds that of steel. It has good casting properties and plastic processing properties, good electrical and thermal conductivity, good corrosion resistance and weldability, and can be used as a structural material. It is widely used in aerospace, aviation, transportation, construction, electromechanical, light chemicals and daily necessities.
[0003] However, there is a clamp that can adapt to aviation aluminum alloy parts of different specifications. Since it is used to limit clamp parts of different specifications, it needs to fit the surface of the parts more closely to avoid the lack of fit and reduced clamping stability. The angle is fixed after limit clamping, so that the angle of subsequent processing operations is fixed. The inability to adjust the angle will reduce the work efficiency and practicality of the limit clamping. Summary of the invention
[0004] In view of the above problems, an embodiment of the present application provides a clamp that is adaptable to aviation aluminum alloy parts of different specifications to solve the problem that the existing clamp that is adaptable to aviation aluminum alloy parts of different specifications is required to fit the surface of the parts more closely to avoid the inability to fit and reduce the stability of the clamping. The angle is fixed after the limit clamping, so that the angle of subsequent processing operations is fixed, and the inability to adjust the angle will reduce the work efficiency and practicality of the limit clamping.
[0005] The embodiment of the present application provides a fixture for aviation aluminum alloy parts that can adapt to different specifications, including: an operating table, a first motor is fixedly installed at the bottom of the operating table, a first rotating rod is fixedly installed at the top of the first motor, the first rotating rod passes through the operating table from the center, a first gear is fixedly installed at the top of the first rotating rod, a second gear is meshed and connected on the surface of the first gear, the second gear is installed on the outer wall of the connecting rod, and a placement plate is fixedly installed at the top of the connecting rod.
[0006] Through the above scheme, when parts of different specifications are placed on the placement plate, the first motor is driven to drive the first gear to rotate, and the second gear is driven to rotate through the meshing of the first gear, so that the second gear meshes and rotates on the surface of the gear belt with the first gear as the center, and then the connecting rod is driven to rotate through the second gear, so the connecting rod also drives the placement plate to rotate, and the angle is adjusted by the rotation of the placement plate, and the angle makes the limit clamp more useful and also improves the subsequent work efficiency.
[0007] In some embodiments, the second gear surface is meshedly connected with a gear belt, the gear belt is installed on the inner wall of the groove, and the groove is opened at the center of the top of the operating table.
[0008] Through the above solution, when the second gear meshes and rotates on the surface of the gear belt with the first gear as the center, the meshing between the gears is more stable, avoiding deviation during rotation.
[0009] In some embodiments, the bottom end of the connecting rod is movably sleeved inside the annular groove, and the annular groove is opened at the bottom end of the inner wall of the groove.
[0010] Through the above solution, when the second gear meshes and rotates on the surface of the gear belt with the first gear as the center, the connecting rod also moves inside the annular groove, so the annular groove plays a good role in limiting and stabilizing.
[0011] In some embodiments, a second motor is installed at the center position of the inner wall of the placement plate, a second rotating rod is fixedly installed on the top of the second motor, a first bevel gear is fixedly installed on the top of the second rotating rod, a second bevel gear is meshingly connected to the surface of the first bevel gear, a screw is fixedly installed on one side of the second bevel gear, a threaded block is threadedly connected to the surface of the screw, and a limiting block is installed on the top of the threaded block.
[0012] Through the above scheme, parts of different specifications are placed on the placement plate, and the second motor is driven to drive the second rotating rod to rotate, and then the first bevel gear is driven to rotate, and the second bevel gears on the four sides are driven to rotate through the meshing of the first bevel gear, and then the screw is driven to rotate, so that the threaded block is threaded on the surface of the screw, thereby driving the limit block to fit on the top of the placement plate and move, and parts of different specifications are clamped by the limit blocks on the four sides, and the drive makes the clamping more stable.
[0013] In some embodiments, a plurality of limiting grooves are formed on one side of the limiting block, a movable rod is movably sleeved inside the limiting groove, and a soft pad is fixedly installed on one side of the movable rod.
[0014] Through the above scheme, when the limit block clamps parts of different specifications during movement, the force will also push the soft pad to one side, so that the movable rod also slides in the limit groove, and through the telescopic push, the pushing pad can better fit the surface of the part, and the several soft pads on one side of the limit block provide stability and firmness for the limit clamping.
[0015] In some embodiments, a telescopic spring is fixedly mounted on one side of the soft cushion, and the telescopic spring is movably sleeved on the outer wall of the movable rod.
[0016] Through the above scheme, through the elasticity of the telescopic spring, when the limit block clamps parts of different specifications during movement, the soft pad will also fit the surface of the part, and at the same time, the force will push the soft pad to move to one side, so the elasticity will push the soft pad to better fit the surface of the part, providing stability and firmness for the limit clamping.
[0017] In some embodiments, the top of the placement plate is symmetrically provided with slots on four sides, and the threaded block is movably sleeved inside the slots.
[0018] Through the above scheme, the limit block is fitted on the top of the placement plate and moved through the slot. At the same time, the thread block also slides in the slot when it moves on the surface of the screw. The slot also plays the role of limiting the thread block, preventing the thread block from being unable to move and rotate synchronously with the screw.
