Description

Technical Field

[0001] This utility model relates to the technical field of rotary part processing positioning mechanism that facilitates quick clamping, specifically a rotary part processing positioning mechanism that facilitates quick clamping. Background Technology

[0002] Components are the building blocks of products in all industries. For example, aerospace equipment requires a variety of components during the production process. The quality of the processing of aerospace equipment components directly affects the safety of the aerospace equipment. When processing aerospace equipment components, it is often necessary to fix the components in a designated position before processing.

[0003] Currently, Chinese Patent No. CN219703970U discloses a positioning mechanism for welding parts, relating to the field of welding parts technology. This positioning mechanism aims to solve the technical problem of poor applicability and flexibility in the welding positioning of parts of different volumes under the existing technology. The positioning mechanism includes a base with an adjustment groove at the upper end. A first motor is installed at the right end of the adjustment groove, and a first threaded shaft is installed at the left end of the output shaft of the first motor. Symmetrical connecting seats are connected to the outside of the first threaded shaft. The positioning mechanism adopts a foldable design, which can store the support rod into the adjustment groove of the base, making it easy to transport to the vicinity of the parts to be welded, thus improving the flexibility and convenience of the positioning mechanism. The support rod is driven to move synchronously inward or outward through the two connecting seats. After adjusting the spacing to match the volume of the parts, the edge of the parts is placed into the positioning assembly, and the front, back, upper and lower ends of the two edges of the parts are stably clamped and positioned.

[0004] The aforementioned component welding and positioning mechanism still has some problems in use. The positioning components rigidly clamp the front and rear, upper and lower ends of the two ends of the component. This clamping method can ensure the stability during welding, but it also makes it difficult to flip the component without disassembling it after it is fixed. For example, if the bottom surface of the component needs to be processed, it needs to be removed from the clamping position, flipped over, and the spacing readjusted and clamped again, which is a cumbersome operation process.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-4 This embodiment provides a rotary part processing positioning mechanism that facilitates quick clamping, including a worktable 100. A support plate 101 is fixedly installed on the top of the worktable 100. A rotating column 103 is rotatably inserted into the left side of the support plate 101. Bearings 104 are sleeved on the outer circular surfaces of both ends of the rotating column 103. A rotating component for rotating the rotating column 103 is provided inside the support plate 101. Two sets of bearings 104 are respectively embedded in the corresponding side surfaces of the support plate 101. A placement plate 102 is fixedly connected to the right end of the rotating column 103. A clamping component for clamping the parts is provided on the surface of the placement plate 102.

[0029] The rotating component includes a cavity 105 formed inside the support plate 101 and located on the outer circumferential surface of the rotating column 103 at its center. A worm gear ring 202 is fixedly sleeved on the outer circumferential surface of the rotating column 103 located in the cavity 105. The teeth of the worm gear ring 202 mesh with a worm 201. The two ends of the worm 201 are rotatably connected to the inner walls of the corresponding side cavities 105. One end of the worm 201 penetrates the cavity 105 and extends to the outer side of the support plate 101. One end of the worm 201 located on the outer side of the support plate 101... A handwheel 200 is fixedly connected to the end. By rotating the handwheel 200 on the outside of the support plate 101, the handwheel 200 drives the worm gear 201 fixedly connected to it to rotate. Since the worm gear 201 meshes with the worm wheel ring 202 fixedly sleeved on the rotating column 103, the rotation of the worm gear 201 will drive the worm wheel ring 202 to rotate, thereby causing the rotating column 103 to rotate under the support of the bearing 104. This causes the placement plate 102 to drive the parts to rotate, realizing multi-faceted processing and avoiding frequent disassembly and re-clamping.

[0030] The support plate 101 has a scale ring 400 fixedly connected to its left side surface, and the rotating column 103 has a pointer 401 fixedly connected to its left end for pointing to the scale ring 400. By setting the pointer 401 and the scale ring 400 together, the pointer 401 and the scale ring 400 can intuitively display the rotation angle, making it easy for the operator to accurately position the parts. This is suitable for welding or processing tasks that require a specific angle. At the same time, the scale ring 400 is marked, and it can be quickly and repeatedly adjusted to the same angle, improving the consistency of batch processing. Also, the scale ring 400 and the pointer 401 are located on the left side of the support plate 101, which can avoid damage to the scale ring 400 during processing.

[0031] The clamping component includes a square hole 300 on the left side surface of the placement tray 102. A bidirectional lead screw 309 is rotatably connected to the inner cavity of the square hole 300. One end of the bidirectional lead screw 309 extends upward through the placement tray 102 and has a hexagonal groove 308. Nut seats 301 are threaded to both ends of the bidirectional lead screw 309. Clamping plates 302 are fixedly connected to the right ends of the two sets of nut seats 301. An anti-rotation component is provided at the bottom of the placement tray 102 to fix the bidirectional lead screw 309 and prevent it from rotating. With the clamping component, the bidirectional lead screw 309 drives the clamping plates 302 to move synchronously, which can automatically center and clamp parts of different sizes, improving versatility.

[0032] Among them, rubber pads 303 are fixedly connected to the opposite ends of the two sets of clamping plates 302. With the setting of rubber pads 303, the rubber pads 303 can ensure the clamping force while avoiding damage to the surface of the parts. It is especially suitable for multi-faceted precision machining scenarios. Compared with the defects of traditional rigid clamping that easily causes surface scratches, it reduces rework and material waste caused by surface damage.

[0033] The anti-rotation component includes a square groove 304 located in the lower right part of the placement plate 102. The opening of the square groove 304 is aligned with the other end surface of the bidirectional lead screw 309. An abutment plate 306 is slidably inserted into the inner cavity of the square groove 304. A hand-tightening bolt 307 is threadedly connected to the surface of the placement plate 102 and located at the end of the abutment plate 306. The end of the hand-tightening bolt 307 extends into the inner cavity of the square groove 304 and is fixedly connected to an adapter rod 305. One end of the adapter rod 305 is rotatably inserted into the end of the abutment plate 306. With the anti-rotation component, the hand-tightening bolt 307 drives the adapter rod 305 to rotate. The adapter rod 305 pushes the abutment plate 306 to slide in the square groove 304 and abut against the end surface of the bidirectional lead screw 309. The bidirectional lead screw 309 can be locked and unlocked without tools, improving processing efficiency.

[0034] The end of the contact plate 306 is arranged in a corresponding arc shape to the end of the bidirectional lead screw 309. The arc-shaped contact makes the pressure distribution more uniform, avoids damage to components caused by local stress concentration, and extends service life. At the same time, the larger contact area can provide stronger frictional resistance, effectively preventing the bidirectional lead screw 309 from rotating due to external force or vibration, and ensuring stable clamping state during processing.

[0035] Working principle;

[0036] First, after placing the parts on the placement tray 102, insert a tool into the hexagonal groove 308 at the top of the double-acting screw 309 and rotate it. The double-acting screw 309 will rotate accordingly. Since the threads at both ends of the double-acting screw 309 turn in opposite directions and are threadedly connected to the nut seats 301 respectively, when the double-acting screw 309 rotates, the two sets of nut seats 301 will move outward synchronously along the inner wall of the square hole 300. The movement of the nut seats 301 will drive the clamping plate 302 fixed at its right end away, thereby fixing the parts. Rotating the double-acting screw 309 in the opposite direction will release the parts from the fixation. At the same time, the rubber pad 303 at the opposite end of the clamping plate 302 can increase the friction between the parts and improve the clamping stability, while avoiding damage to the surface of the parts.

[0037] After the parts are fixed by the double-acting screw 309, in order to prevent the parts from loosening due to the rotation of the double-acting screw 309, an anti-rotation component is required for fixing. Rotate the hand-tightening bolt 307 on the surface of the placement plate 102. The hand-tightening bolt 307 drives the adapter rod 305 to rotate. The adapter rod 305 pushes the abutment plate 306 to slide in the square groove 304 and abut against the end surface of the double-acting screw 309.

[0038] Furthermore, the end of the abutment plate 306 is arc-shaped, corresponding to the end of the bidirectional lead screw 309. After sliding, the abutment plate 306 will fit tightly against the end of the bidirectional lead screw 309, using friction to limit the rotation of the bidirectional lead screw 309, ensuring that the parts are always in a stable clamping state during the processing.

[0039] At this point, the parts are processed;

[0040] When it is necessary to adjust the angle of the component, the operator turns the handwheel 200 on the outside of the support plate 101. The handwheel 200 drives the worm gear 201 fixedly connected to it to rotate. Since the worm gear 201 meshes with the worm wheel ring 202 fixedly sleeved on the rotating column 103, the rotation of the worm gear 201 will drive the worm wheel ring 202 to rotate, thereby causing the rotating column 103 to rotate under the support of the bearing 104. When the rotating column 103 rotates, the placement plate 102 connected to its right end rotates synchronously, thereby realizing the angle adjustment of the component.

[0041] Meanwhile, the pointer 401 at the left end of the rotating column 103 rotates, making it convenient for the operator to observe and control the rotation angle to meet different processing needs.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
