Description

Technical Field

[0001] This utility model belongs to the technical field of tooling for fastener processing, and specifically relates to a tooling for aerospace fastener processing. Background Technology

[0002] Aerospace fastener processing fixture is a tooling used to fix fasteners. It typically includes a base plate, a clamping mechanism mounted on top of the base plate, and a power mechanism mounted on the clamping mechanism. When in use, the operator installs the fastener to be processed on the clamping mechanism and then starts the power mechanism to fix the fastener.

[0003] However, in practice, existing clamping mechanisms use a planar structure for clamping, which means that when clamping fasteners, manual assistance is required from the operator due to the planar clamping and limiting mechanism. Furthermore, it is inconvenient to coordinate the operation when clamping multiple fasteners at once, requiring the operator to frequently load and unload the clamping mechanism, which is time-consuming and labor-intensive. Moreover, only one fastener can be clamped and processed at a time, reducing the processing efficiency of the device and failing to meet the needs of users. Therefore, a tooling for aerospace fastener processing is proposed. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing a tooling for processing aerospace fasteners. It not only meets the basic requirement of clamping fasteners, but also allows multiple fasteners to be clamped simultaneously through the clamping mechanism, saving time and effort, avoiding frequent loading and unloading of fasteners by workers, improving the processing efficiency of the device, and meeting people's needs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a tooling for processing aerospace fasteners, including a base plate, a support plate slidably disposed on the top of the base plate, multiple rotating shafts rotatably disposed on the inner end of the support plate, cylinders respectively disposed on the inner end of the multiple rotating shafts, conical holes I disposed inside the multiple cylinders, multiple rubber strips I disposed inside the conical holes, a support plate disposed on the top right side of the base plate, multiple rotating shafts rotatably disposed on the inner end of the support plate, frustums respectively disposed on the inner end of the multiple rotating shafts, conical holes II disposed in the middle of the multiple frustums, multiple rubber strips II disposed inside the multiple conical holes II, multiple V-belt pulleys connected to the rotating shafts disposed on the outer end of the support plate, V-belts disposed on adjacent V-belt pulleys, an L-shaped plate disposed on the outer end of the support plate, a second rotary motor connected to the V-belt pulleys disposed on the L-shaped plate, and the second rotary motor and the V-belt pulleys being connected by a coupling.

[0006] As a further improvement of this utility model, multiple slides are provided on the top left side of the base plate. A lead screw is rotatably installed inside the middle slide, and a slide body is slidably installed inside the middle slide. The slide body is screwed to the lead screw. Guide rods are provided inside the front and rear slides respectively, and sliders are slidably installed inside the front and rear slides respectively. The sliders are slidably connected to the guide rods. The tops of the sliders and slide bodies are connected to the support plate. A first rotary motor connected to the lead screw is provided on the left side of the base plate. The first rotary motor is connected to the lead screw through a coupling. A rotary seat connected to the rotary shaft is provided on the support plate, and a rotary seat connected to the rotary shaft is provided on the support plate.

[0007] As a further improvement of this utility model, the support plate is provided with multiple through slots corresponding to the cylinders, and a semi-cylinder is slidably arranged inside each of the multiple through slots. A connecting plate connected to the semi-cylinder is slidably arranged inside each of the multiple through slots. A horizontal plate is provided on the left side of the multiple connecting plates, and a guide block is provided at the bottom of the horizontal plate. A power mechanism connected to the guide block is provided on the left side of the support plate. There is a gap between the semi-cylinder and the cylinder. The power mechanism includes a U-shaped plate provided on the left side of the support plate. A lead screw rotatably connected to the U-shaped plate is rotatably arranged on the support plate. The lead screw is screwed to the guide block. A third rotary motor connected to the lead screw is provided on the left side of the U-shaped plate. The third rotary motor is connected to the lead screw through a coupling. A switch is provided on the top right side of the bottom plate. The switch is electrically connected to the first rotary motor, the second rotary motor, and the third rotary motor.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] Firstly, this design includes a first rotary motor. The rotation of the first rotary motor drives the lead screw to rotate, which in turn drives the slide body inside the slide rail to move, thereby moving the support plate. At the same time, the slider at the bottom of the support plate slides along the guide rod inside the slide groove. At this time, the cylinder and the frustum on the support plate approach each other, thus effectively clamping and fixing the fasteners.

[0010] Secondly, this design includes a second rotary motor. The rotation of the second rotary motor drives the V-belt pulley to rotate, and the rotation of the V-belt pulley drives the V-belt to move. This causes multiple V-belt pulleys to drive the rotating shaft to rotate, thereby driving the fastener to rotate and thus processing the fastener better.

[0011] Thirdly, this design includes a third rotary motor. The rotation of the third rotary motor drives the lead screw to move, which in turn drives the horizontal plate to move. The movement of the horizontal plate causes the connecting plate to slide inside the through groove, thereby causing the semi-cylinder to slide inside the through groove. This allows the semi-cylinder to extend out of the inner end of the support plate, thus supporting the fastener and facilitating the clamping of multiple workpieces at once.

[0012] Fourth, this design includes a switch that, when activated, powers the first, second, and third rotary motors, allowing for power cut-off in emergencies. Attached Figure Description

[0021] like Figure 1 , 2 As shown in Figure 3, multiple slide rails 110 are provided on the top left side of the base plate 101.

The sliders 113 are slidably connected to the guide rods 114. The tops of the sliders 113 and sliders 111 are connected to the support plate 102. The base plate 101... A first rotary motor 207 connected to a lead screw 112 is provided on the left side. The first rotary motor 207 and the lead screw 112 are connected by a coupling.

[0023] How to use this utility model:

[0024] When using the device, the operator first turns on switch 208. Turning on switch 208 powers the first rotary motor 207, the second rotary motor 118, and the third rotary motor 206. The operator then turns on the third rotary motor 206. The rotation of the third rotary motor 206 causes the lead screw 205 to move. The movement of the lead screw 205 causes the horizontal plate 202 to move. The movement of the horizontal plate 202 causes the connecting plate 201 to slide inside the through groove 119, thereby causing the semi-cylinder 120 to slide inside the through groove 119, so that the semi-cylinder 120 extends out of the inner end of the support plate 102.

[0025] At this point, the worker places the fastener to be processed inside the conical hole 105 and on top of the semi-cylinder 120. The worker then starts the first rotary motor 207. The rotation of the first rotary motor 207 drives the lead screw 112 to rotate. The rotation of the lead screw 112 drives the slide body 111 inside the slide rail 110 to move, thereby moving the support plate 102. At the same time, the slider 113 at the bottom of the support plate 102 slides along the guide rod 114 inside the slide groove. At this point, the cylinder 104 on the support plate 102 approaches the frustum 109. The worker then places the fastener away from the end of the conical hole 105 inside the second conical hole, thereby clamping the fastener through the conical hole 105 and the second conical hole.

[0026] At this time, the staff starts the second rotary motor 118. The rotation of the second rotary motor 118 drives the V-belt pulley 115 to rotate. The rotation of the V-belt pulley 115 drives the V-belt 116 to move, thereby causing multiple V-belt pulleys 115 to drive the rotating shaft 108 to rotate, thereby driving the fastener to rotate, so as to facilitate the processing of the workpiece.
