Description

Technical Field

[0001] This utility model relates to the field of aerospace products, and in particular to a positioning fixture for lifting points of aerospace products. Background Technology

[0002] An existing patent (publication number: CN108394806A) proposes a lifting point positioning fixture for aerospace products. It includes a lifting and mounting frame with symmetrical fixed clamps on both sides of its bottom end. A fixed ear plate is fixedly installed at the bottom end of the lifting and mounting frame at the front end of the fixed clamps. A connecting rod is movably hinged to the upper end of a movable clamp. Two downward sliding rods are slidably engaged in a vertical sliding groove on the front end face of the lifting and mounting frame, and the upper ends of the two downward sliding rods are fixedly connected by a connecting beam. The connecting beam is movably located in a horizontal sliding groove, and the outer end face of the connecting beam is fixedly connected to the drive end of a cylinder, which is fixedly mounted on a drive shaft. However, this device, which states that "the lifting and mounting frame has symmetrical fixed clamps on both sides of its bottom end," relies on the fixed clamps at the bottom of the lifting and mounting frame to lift and hold aerospace products. When holding box-shaped products, the clamping area of ​​the fixed clamps is relatively small and prone to shifting, thus having certain limitations. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing a clamping fixture for aerospace products. This fixture uses two sets of clamping blocks at the lower part of the equipment's crossbeam to hold materials. When clamping cylindrical or box-shaped materials, the nuts on the side of the equipment's bolt platform are removed, and the pins inside the pin slots are pulled out. This releases the pins from the clamping blocks, allowing the clamping blocks at the lower part of the clamping column to be removed. This enables the clamping blocks to be adjusted by flipping and changing the toothed clamps and circular clamps according to the shape of the material, increasing the clamping area for different materials and thus enhancing the adaptability of the equipment.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A positioning fixture for lifting points of aerospace products includes a crossbeam, a bolt platform, a support roller, a clamping column, a pin plate, a pin, and a nut. The upper part of the crossbeam is fixedly connected to the bolt platform. The crossbeam has an internal cavity with a screw groove inside. A screw shaft is located inside a double-threaded rod. The screw groove is adapted to the screw shaft and is connected to the screw shaft, which rotates within the groove. The front part of the crossbeam is fixedly connected to a screw motor, and the output shaft of the screw motor is fixedly connected to the screw shaft. The upper part of the positioning platform is fixedly connected to an internally threaded cylinder, which is threaded onto the side of the double-threaded rod. The lower part of the internally threaded cylinder is fixedly connected to a hanger. The side of the hanger is fixedly connected to a secondary support. The upper part of the secondary support is fixedly connected to a support roller shaft, which is adapted to the support roller and is connected to the roller, allowing the roller to rotate on the side of the shaft.

[0006] The support roller rotates on the side of the equipment beam, and the lower part of the equipment beam is fixedly connected to the clamping column. The clamping block has a clamping column slot inside, and the clamping column is adapted to the clamping column slot.

[0007] The clamping pin is connected to the clamping pin slot, the clamping pin slot is inserted into the side of the clamping pin, and both the side of the clamping pin slot and the side of the clamping pin have pin slots, and the pin plate side is fixedly connected by a pin.

[0008] The pin slot is adapted to the pin, the pin slot is connected to the pin, the pin is inserted into the pin slot, the front part of the pin has a threaded post, and the nut is threadedly connected to the front part of the threaded post. Beneficial effects

[0009] 1. During the use of this aerospace product lifting point positioning fixture, the aerospace product materials are clamped by two sets of clamping blocks at the lower part of the equipment beam. If it is necessary to clamp cylindrical or box-shaped materials, the nuts on the side of the equipment bolt table are removed, and the pins inside the pin slots are pulled out, so that the pins release the locking of the clamping blocks. Then, the clamping blocks at the lower part of the clamping column are pulled out, so that the clamping blocks can be flipped and adjusted according to the shape of the material, increasing the clamping area for different materials, thereby increasing the adaptability of the equipment.

[0010] 2. During the use of this aerospace product lifting point positioning fixture, the screw motor at the front of the equipment beam drives the double threaded rod to rotate, which in turn drives two sets of clamping blocks to clamp the material. At the same time, the double threaded rod works in conjunction with the four sets of support rollers on the upper part of the auxiliary support to position the lifting frame on the side of the equipment beam, thus avoiding the clamping blocks from tilting or shifting due to unilateral force, thereby increasing the stability of the equipment.

[0011] 3. During the use of this aerospace product lifting point positioning fixture, the material is clamped by the clamping block under the equipment beam, and the clamping block is limited and fixed by two sets of pins on the side of the pin plate, thereby increasing the fastening range and further increasing the stability of the equipment.

[0021] A positioning fixture for lifting points of aerospace products includes a crossbeam 01, a bolt table 02, a support roller 13, a clamping post 14, a pin plate 18, a pin 19, and a nut 21. The upper part of the crossbeam 01 is fixedly connected to the bolt table 02. The crossbeam 01 has an inner cavity 03, and the inner cavity 03 has a screw groove 04. A double-threaded rod 05 has a screw shaft 06 inside. The screw groove 04 is adapted to the screw shaft 06 and is connected to the screw shaft 06. The screw shaft 06 rotates within the screw groove 04. The front part of the equipment beam 01 is fixedly connected to the screw motor 07. The output shaft of the screw motor 07 is fixedly connected to the screw shaft 06. The upper part of the positioning table 08 is fixedly connected to the internal threaded cylinder 09. The internal threaded cylinder 09 is threadedly connected to the side of the double threaded rod 05. The lower part of the internal threaded cylinder 09 is fixedly connected to the hanger 10. The side of the hanger 10 is fixedly connected to the auxiliary support 11. The upper part of the auxiliary support 11 is fixedly connected to the support roller shaft 12. The support roller shaft 12 is adapted to the support roller 13. The support roller shaft 12 is connected to the support roller 13. The support roller 13 rotates on the side of the support roller shaft 12.

[0022] Example 2:

[0023] The roller 13 of this utility model rotates on the side of the equipment beam 01. During the use of the aerospace product lifting point positioning fixture, the screw motor 07 at the front of the equipment beam 01 drives the double threaded rod 05 to rotate, so that the double threaded rod 05 drives the two sets of clamping blocks 15 to clamp the material. At the same time, it cooperates with the four sets of rollers 13 on the upper part of the auxiliary support 11 to position the hanger 10 on the side of the equipment beam 01, so as to avoid the clamping block 15 tilting and shifting due to unilateral force, thereby increasing the stability of the equipment. The lower part of the equipment beam 01 is fixedly connected to the clamping column 14. The clamping block 15 has a clamping column slot 16 inside, and the clamping column 14 is adapted to the clamping column slot 16.

[0024] Example 3:

[0025] The clamping column 14 of this utility model is connected to the clamping column slot 16. The clamping column slot 16 is inserted into the side of the clamping column 14. Both the side of the clamping column slot 16 and the side of the clamping column 14 have pin slots 17. The pin plate 18 is fixedly connected by pins 19 on its side. During the use of the aerospace product lifting point positioning fixture, the material is clamped by the clamping block 15 under the equipment beam 01, and the clamping block 15 is limited and fixed by the two sets of pins 19 on the side of the pin plate 18, thereby increasing the tightening range and further increasing the stability of the equipment.

[0026] Example 4:

[0027] The pin groove 17 of this utility model is adapted to the pin 19. The pin groove 17 is connected to the pin 19. The pin 19 is inserted into the pin groove 17. The front part of the pin 19 has a threaded post 20. The nut 21 is threadedly connected to the front part of the threaded post 20.

[0028] Example 5:

[0029] The pin 19 of this utility model is fixed inside the pin groove 17 by the nut 21. During the use of the aerospace product lifting point positioning fixture, the aerospace product material is clamped by the two sets of clamping blocks 15 at the lower part of the equipment beam 01. If it is necessary to clamp cylindrical or box-shaped materials, the nut 21 on the side of the equipment bolt table 02 is removed and the pin 19 inside the pin groove 17 is pulled out, so that the pin 19 releases the locking of the clamping block 15 and the clamping block 15 at the lower part of the clamping column 14 is pulled out. Thus, the clamping block 15 can be flipped and adjusted according to the shape of the material to increase the clamping area for different materials, thereby increasing the adaptability of the equipment. The front part of the clamping block 15 is fixedly connected to the toothed clamp 22, and the rear part of the clamping block 15 is fixedly connected to the circular clamp 23.
