Description

Technical Field

[0001] This invention belongs to the field of tooling and fixture technology, and relates to a tooling for rapid assembly of parts. Background Technology

[0002] Parts assembly is a common process in industrial manufacturing. Parts are clamped and fixed by tooling fixtures before being processed. Some parts of aircraft also need to be positioned and processed. Some irregular parts do not have suitable assembly tooling for clamping and need to be aligned manually. Positioning and processing is prone to deviations, which will affect the subsequent use of the workpiece. Summary of the Invention

[0003] To address the problems mentioned in the background art, the present invention provides a quick assembly tooling for positioning and drilling of aircraft parts assembled from a base plate and a partition plate.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A quick assembly fixture for parts includes an operating platform 1, support shafts 2, a flipping support mechanism 3, a base plate positioning mechanism 4, and a partition plate positioning mechanism 5. The operating platform 1 has support shafts 2 at both ends, with the ends of the two support shafts 2 connected to the flipping support mechanism 3. The flipping support mechanism 3 supports and flips the operating platform 1. The base plate positioning mechanism 4 and the partition plate positioning mechanism 5 are fixedly installed on the operating platform 1, respectively used to position and fix the base plate and partition plate of the parts. Specifically:

[0006] The operating platform 1 is a box-type structure with an open bottom. Two operating holes are opened along the center line on its upper surface, and support shafts 2 are provided at the center of both ends in the length direction.

[0007] The flipping support mechanism 3 includes a support base 31, a support frame 32, a bottom beam 33, a worm gear box 34, a handwheel 35, a caster wheel 36, an internal threaded cylinder 37, a support screw 38, and a support plate 39. Two support frames 32 are arranged opposite each other, with a base beam 33 fixedly connected between them. Each support frame 32 has a support base 31 fixed to its upper end. The support base 31 is hinged to two support shafts 2, allowing the operating platform 1 to rotate around the support shafts 2. The worm gear box 34 is fixed on one of the support frames 32, and its output shaft is connected to the support shaft 2 on that side. A handwheel 35 is connected to the input shaft of the worm gear box 34 for rotating the operating platform 1. Universal wheels 36 are fixed to both ends of the lower surface of each support frame 32 for moving the entire quick assembly fixture. Internal threaded cylinders 37 are fixed to both ends of the bottom side of each support frame 32. Support screws 38 are threadedly engaged with the internal threaded cylinders 37. Support plates 39 are fixed to the lower ends of each support screw 38. By turning the support screws 38, the support plates are brought into contact with the ground to prevent the quick assembly fixture from moving.

[0008] The base plate positioning mechanism 4 includes three base plate support blocks 41, which are arranged along the center line of the operating platform 1 and fixed on the operating platform 1. The base plate support blocks 41 on both sides are fixed to the two ends of the upper surface of the operating platform 1, and the base plate support block 41 in the middle is fixed between two operating holes. The part base plate is placed on the top surface of the three base plate support blocks 41. The base plate support blocks 41 on both sides are provided with clamps 42 on the back side, one of which is a vertical clamp and the other is a push-pull clamp. The top surface of the middle base plate support block 41 and the base plate support block 41 with the push-pull clamp is provided with a first hook-shaped screw 43, the tail end of which is screwed into a first locking nut 44. The two work together to press the part base plate onto the top surface of the base plate support block 41.

[0009] The partition positioning mechanism 5 includes a transition base 51, a gantry frame 52, positioning blocks 53, a second hook-shaped screw 54, and a second locking nut 55. Two transition bases 51 are provided, with the gantry frame 52 fixedly connected between them. Two positioning blocks 53 are symmetrically fixed on one side of the top beam of the gantry frame 52. The opposite sides of the positioning blocks 53 are set as inclined surfaces for positioning the partition parts. The second hook-shaped screw 54 is symmetrically threaded through the gantry frame 52 between the two positioning blocks 53, and its tail end is screwed into the second locking nut 55. The two mechanisms work together to position the partition parts. The partition is pressed against the gantry frame 52; several partition positioning mechanisms 5 are arranged along the length of the operating platform 1 and fixed to the operating platform 1 through the adapter base 51. The partition positioning mechanisms 5 are all located between the bottom plate support blocks 41 on both sides, and the lower end surface of the top crossbeam of the gantry frame 52 is higher than the top surface of the bottom plate support block 41. Each partition positioning mechanism 5 is symmetrically arranged along the center line of the operating platform 1. The size and position of the partition positioning mechanism 5 are set according to the size and position of the part partition, and are used to position the relative position of the part partition and the part bottom plate.

[0010] The beneficial effects of this invention are as follows: the base plate is supported by the base plate support block in the base plate positioning mechanism, and the base plate component is positioned and fixed by the clamps on both sides and the first hook-shaped screw. The partition component is restricted by the gantry frame and positioning block in the partition positioning mechanism, and the partition component is fixed by the second hook-shaped screw. The base plate component and the partition component can be positioned and fixed in a specific position in the device, so that multiple partition components are aligned with one base plate component. The angle of the operating platform can be adjusted by rotating the handwheel to facilitate drilling of the fixed base plate component and partition component. After the base plate and partition are removed, the bolt connection between the two is convenient. Attached Figure Description

[0016] The technical solution of the present invention will now be clearly and completely described. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments derived by those skilled in the art based on the embodiments of the present invention through modifications or adjustments are within the protection scope of the present invention.

[0017] This embodiment provides a quick assembly fixture for parts. The quick assembly fixture includes an operating platform 1, a support shaft 2, a flipping support mechanism 3, a base plate positioning mechanism 4, and a partition plate positioning mechanism 5. Figure 1 As shown.

[0018] The operating platform 1 is a box-type structure with an open bottom. Two operating holes are opened along the center line on its upper surface, allowing the operator to operate from below the operating platform 1. Support shafts 2 are provided at the center of both ends of the operating platform 1.

[0019] The flipping support mechanism 3 includes a support base 31, a support frame 32, a bottom beam 33, a worm gear box 34, a handwheel 35, a caster wheel 36, an internal threaded cylinder 37, a support screw 38, and a support plate 39. Two support frames 32 are arranged opposite each other, with a base beam 33 fixedly connected between them. Each support frame 32 has a support base 31 fixed to its upper end. The support base 31 is hinged to the two support shafts 2 via bearings, allowing the operating platform 1 to rotate around the support shafts 2. The worm gear box 34 is fixed to one of the support frames 32, with its output shaft coaxially connected to the support shaft 2 on that side. A handwheel 35 is connected to the input shaft of the worm gear box 34. Rotating the handwheel 35 rotates the worm, causing the worm gear and support shaft 2 to rotate, thereby adjusting and locking the rotation angle of the operating platform 1 for easy operation of the workpiece. Universal wheels 36 are fixed to both ends of the lower surface of each support frame 32 for moving the entire quick assembly fixture. Internal threaded cylinders 37 are fixed to both ends of the bottom side of each support frame 32. Support screws 38 are threaded into the internal threaded cylinders 37. Support plates 39 are fixed to the lower ends of each support screw 38. Tightening the support screws 38 causes the support plates to contact the ground, preventing the quick assembly fixture from moving.

[0020] like Figure 2 As shown, the base plate positioning mechanism 4 includes three base plate support blocks 41, which are arranged along the center line of the operating platform 1 and fixed on the operating platform 1. The base plate support blocks 41 on both sides are fixed to the two ends of the upper surface of the operating platform 1, and the base plate support block 41 in the middle is fixed between two operating holes. The part base plate is placed on the top surface of the three base plate support blocks 41. The base plate support blocks 41 on both sides are provided with clamps 42 on their back sides. One of them is a vertical clamp and the other is a push-pull clamp, which are used to fix the part base plate on the base plate support block 41. The top surface of the middle base plate support block 41 and the base plate support block 41 with the push-pull clamp is provided with through holes for the first hook-shaped screw 43 to pass through. The tail end of the first hook-shaped screw 43 is screwed into the first locking nut 44. After the first hook-shaped screw 43 passes through the notch on the part base plate, the first locking nut 44 is tightened to help fix the part base plate.

[0021] like Figure 3 and Figure 4As shown, the partition positioning mechanism 5 includes an adapter base 51, a gantry frame 52, positioning blocks 53, a second hook-shaped screw 54, and a second locking nut 55. Two adapter bases 51 are provided, with the gantry frame 52 fixedly connected between them. Two positioning blocks 53 are symmetrically fixed to one side of the top beam of the gantry frame 52. The opposite sides of the positioning blocks 53 are set as inclined surfaces. The partition plate fits into the positioning blocks 53 and the gantry frame 52 in an arch-like shape for positioning. Symmetrical through holes are provided on the gantry frame 52 between the two positioning blocks 53 for the second hook-shaped screw 54 to pass through. The second hook-shaped screw 54 passes through the notch in the partition plate. The part is then pressed onto the partition plate, and its tail end is screwed into the second locking nut 55 to press the partition plate onto the gantry frame 52. Several partition plate positioning mechanisms 5 are arranged along the length of the operating platform 1 and fixed to the operating platform 1 through the adapter base 51. The partition plate positioning mechanisms 5 are all located between the bottom plate support blocks 41 on both sides, and the lower end surface of the top crossbeam of the gantry frame 52 is higher than the top surface of the bottom plate support block 41. Each partition plate positioning mechanism 5 is symmetrically arranged along the center line of the operating platform 1. The size and position of the partition plate positioning mechanism 5 are set according to the size and position of the part partition plate, and are used to position the relative position of the part partition plate and the part bottom plate.

[0022] Working principle: The part base plate is placed on the base plate support block 41 by passing through each gantry 52 from one side. The part base plate is fixed from both sides by clamps 42 on the base plate support blocks 41. The first hook-shaped screw 43 passes through the notch in the part base plate and the first locking nut 44 is rotated to make the hook head of the first hook-shaped screw 43 press down on the part base plate for fixation. Then, multiple part partitions are placed and attached to each gantry 52 and positioning block 53 respectively. The second hook-shaped screw 54 passes through the notch in the part partition and the second locking nut 55 is rotated to make the hook head of the second hook-shaped screw 54 press against the part partition for fixation. At this time, each part partition is in its specific position relative to the part base plate, realizing the alignment and fixation of the part base plate and the part partitions. Then, the operating platform 1 is rotated to a suitable angle by rotating the handwheel 35, and holes are drilled in the part base plate and part partitions. After that, the part partitions and part base plate are removed and connected by bolts.

[0023] The above embodiments are merely illustrative of the implementation methods of the present invention, but should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
