Description

Technical Field

[0001] This utility model relates to the field of adsorption positioning equipment, specifically an adaptive adsorption positioning device for large thin-walled parts. Background Technology

[0002] Large thin-walled parts typically refer to large parts with a thickness much smaller than their length and width and complex structures. They are characterized by light weight and high material utilization, but low rigidity and easy deformation. Large thin-walled parts are widely used in aerospace (such as engine blades and fuel tanks), automotive (turbochargers and brake discs), chemical (corrosion-resistant equipment) and other fields to meet the requirements of high performance and lightweight.

[0003] Large thin-walled parts require high precision during processing, making clamping difficult. Suction cups are usually used for adsorption and positioning of thin-walled parts. However, when adsorbing thin-walled parts of different specifications, it is necessary to repeatedly adjust the position of multiple suction cups, which is cumbersome and affects the clamping speed of thin-walled parts, failing to meet the clamping and positioning requirements of different thin-walled parts.

[0024] In one embodiment, such as Figure 1-5 As shown, an adaptive adsorption positioning device for large thin-walled parts includes a positioning disk 1, and further includes:

[0025] The positioning rod 4 is provided with a support plate 2 slidably mounted on the bottom of the positioning disk 1. A fixing sleeve 3 is fixedly mounted inside the support plate 2, and a positioning rod 4 is slidably mounted inside the fixing sleeve 3. A connecting spring 25 is provided at the top of the positioning rod 4, and a vacuum suction cup 6 for adsorbing thin-walled parts is provided at the bottom of the positioning rod 4. A transmission groove 402 is provided on the positioning rod 4. The transmission groove 402 is an inclined groove. A transmission rod 22 is slidably mounted between the two positioning rods 4. A pressure block 23 that cooperates with the transmission groove 402 is provided on the transmission rod 22. The transmission rod 22 is slidably mounted on the support plate 1. At the bottom of the support plate 2, the transmission rod 22 can only move horizontally. Both ends of the transmission rod 22 are provided with slots 221. The support plate 2 is provided with a locking plate 24 that cooperates with the slots 221. The locking plate 24 is elastically installed by a spring. The locking plate 24 locks the transmission rod 22, so that the transmission rod 22 cannot be reset. The support plate 2 is provided with a fixing groove 201 on the outside. The fixing groove 201 is provided with a fixing bolt 401 inside. One end of the fixing bolt 401 passes through the fixing sleeve 3 and is connected to the positioning rod 4. The adjusted positioning rod 4 is fixed by the fixing bolt 401.

[0026] An adjusting cylinder 7 is provided above the positioning disk 1, and an mounting plate 11 is provided above the positioning disk 1. The mounting plate 11 is connected to a slide rail or a hanging rod and can move the thin-walled part adsorbed below and transport the thin-walled part to the processing position. A fixing plate 12 is provided at the center of the mounting plate 11, and a fixing cylinder 8 is fixedly provided at the bottom of the fixing plate 12. The adjusting cylinder 7 is slidably provided inside the fixing cylinder 8. A turntable 18 is provided between the positioning disk 1 and the adjusting cylinder 7. The positioning disk 1 can rotate along the turntable 18. A plurality of guide rods 5 are provided on the positioning disk 1, and one end of the guide rod 5 slides into the interior of the fixing cylinder 8.

[0027] The lifting mechanism is connected to the adjusting cylinder 7 and can drive the adjusting cylinder 7 and the positioning plate 1 to move up and down.

[0028] The adaptive adsorption positioning device for large thin-walled parts uses a lifting mechanism to move the adjusting cylinder 7 and the positioning disk 1 up and down. The positioning disk 1 drives multiple vacuum suction cups 6 to descend. The positioning rod 4 adjusts the height of the vacuum suction cups 6 according to the shape of the thin-walled parts below, so that the vacuum suction cups 6 can adapt to clamping different types of thin-walled parts, realizing the adaptive adjustment of thin-walled parts. The adjustment of the suction cups is more convenient and faster. As an embodiment, the left, right, up and down positions of the various components shown in the attached figure are only a kind of arrangement. The specific positions are set according to specific needs.

[0029] In one embodiment, such as Figure 1-2 As shown, the lifting mechanism includes a connecting plate 9, a rotating plate 10, and a movable plate 13. The mounting plate 11 has a fixed rod 17 and a movable plate 13 inside. The movable plate 13 is slidably mounted on the fixed rod 17. The rotating plate 10 is rotatably mounted on the movable plate 13. The adjusting cylinder 7 has connecting plates 9 on both sides outside. The connecting plates 9 are rotatably connected to the rotating plate 10. The mounting plate 11 has a lead screw 15 inside. The movable plate 13 has a nut 16 that meshes with the lead screw 15. The two ends of the lead screw 15 have external threads with opposite directions of rotation. The lead screw 15 rotates and drives the movable plates 13 on both sides to move closer or further apart. The movable plate 13 drives the adjusting cylinder 7 to move up and down through the rotating plate 10. The adjusting cylinder 7 drives the positioning plate 1 to move up and down.

[0030] In one embodiment, such as Figure 1-2 As shown, a motor 14 is provided on the outside of the mounting plate 11. The rotating end of the motor 14 is connected to the lead screw 15, and the motor 14 drives the lead screw 15 to rotate.

[0031] In one embodiment, such as Figure 1-4 As shown, the positioning disk 1 has a groove 101 inside, and the support plate 2 has a slider 20 on the top, which is slidably disposed inside the groove 101.

[0032] In one embodiment, such as Figure 1-4As shown, a threaded rod 19 is provided inside the groove 101, and a threaded hole 21 that mates with the threaded rod 19 is provided on the slider 20. The threaded rod 19 drives the support plate 2 to move, which facilitates the adjustment of the initial position of the support plate 2.

[0033] The above embodiments of this utility model provide an adaptive adsorption positioning device for large thin-walled parts. The adjusting cylinder 7 drives the positioning disk 1 and the positioning rod 4 to descend. The vacuum suction cup 6 at the bottom of the positioning rod 4 contacts the outer surface of the thin-walled part. When the heights of the two sides of the outer surface of the thin-walled part are different, the positioning rod 4 in contact with the higher side stops moving and is squeezed by the pressure block 23 to the transmission rod 22. The transmission rod 22 moves horizontally and squeezes the positioning rod 4 on the other side. The positioning rod 4 on the other side continues to move downward and contacts the lower side of the thin-walled part, so that the suction cups below the multiple sets of positioning rods 4 all contact the thin-walled part. The clamping plate 24 clamps the transmission rod 22, so that the transmission rod 22 cannot be reset. The positioning rod 4 is fixed by the fixing bolt 401, so that the position adjustment of the multiple sets of suction cups can be realized.

[0034] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
