Description

Technical Field

[0001] The utility model relates to the technical field of through-hole clamps, in particular to a through-hole clamp for a robot. Background Technique

[0002] A through-hole clamp is a high-end positioning fastener used for temporary positioning and fastening of drill templates and sheet metal skins in the aviation industry. Usually, the through-hole clamp is fixed on a robot, and the chuck is driven to move outwards through a thread, so as to be fixed inside.

[0003] When the existing through-hole clamp is in use, since the thickness of the sandwich layer of the chuck is usually fixed, when it is necessary to clamp and fix materials exceeding the thickness of the sandwich layer, the chuck needs to be replaced, and the through-hole clamp needs to be repositioned with the robot, which is cumbersome to operate and not convenient to use. Therefore, a device that is convenient to adjust the thickness of the sandwich layer is needed to clamp different materials. Content of the Utility Model

[0004] The purpose of the utility model is to provide a through-hole clamp for a robot, so as to solve the problem that when the existing through-hole clamp is in use, since the thickness of the sandwich layer of the chuck is usually fixed, when it is necessary to clamp and fix materials exceeding the thickness of the sandwich layer, the chuck needs to be replaced, and the through-hole clamp needs to be repositioned with the robot, which is cumbersome to operate and not convenient to use as mentioned in the above background technique.

[0031] Please refer to Figures 1-3 As shown, this embodiment is a through-hole clamp for a robot, including:

[0032] A through-hole clamp assembly, the through-hole clamp assembly including a base 11;

[0033] An adjustment assembly, the adjustment assembly including a base 21, a sleeve 22, a second chuck 23, a movable tube 24, a retaining ring 25, and a telescopic spring 26;

[0034] The base 21 is sleeved on the outer end of the base body 11. The sleeve 22 is fixedly connected to the central position on the outer side of the base 21. The second chuck 23 is fixedly connected to the peripheral positions on the outer side of the base 21. The movable tube 24 is slidably connected to the inner position at the outer end of the sleeve 22. The retaining ring 25 is fixedly connected to the outer surface of the movable tube 24. The telescopic spring 26 is fixedly connected to the outer side surface of the retaining ring 25;

[0035] The base 21 is used to support the sleeve 22. The sleeve 22 is used to support the movable tube 24. The second chuck 23 is used to clamp the material. The movable tube 24 is used to drive the second chuck 23 to move. The retaining ring 25 is used to support the telescopic spring 26. The telescopic spring 26 is used to drive the retaining ring 25 to reset;

[0036] The through-chuck assembly further includes a screw 12, a gear 13 and a first chuck 14;

[0037] The screw 12 is threadedly connected to the inner position of the base body 11. The gear 13 is fixedly connected to the outer surface of the base body 11. The first chuck 14 is fixedly connected to the outer end of the base body 11;

[0038] The screw 12 is used to drive the first chuck 14 to move. The gear 13 is used to fix the base body 11 and the robot. The first chuck 14 is used to clamp the material;

[0039] The other end of the movable tube 24 is in contact with the outer side of the first chuck 14, and the other end of the telescopic spring 26 is fixedly connected to the inner side surface of the sleeve 22;

[0040] When the first chuck 14 moves outwards, the first chuck 14 drives the movable tube 24 to move outwards, and the movable tube 24 can drive the second chuck 23 to move outwards;

[0041] The second chuck 23 is located at the outer side of the sleeve 22, and the retaining ring 25 is located between the first chuck 14 and the second chuck 23;

[0042] When the movable tube 24 moves outwards, it can drive the retaining ring 25 to move outwards, and the retaining ring 25 then drives the telescopic spring 26 to be compressed;

[0043] Working principle: When it is necessary to clamp materials with a larger sandwich thickness, the base 21 is sleeved at the outer end of the base body 11, so that the second chuck 23 is located outside the first chuck 14. When the screw 12 rotates to drive the first chuck 14 to move outwards, the first chuck 14 moves to drive the movable tube 24 to move outwards. The movable tube 24 drives the retaining ring 25 and the second chuck 23 to move outwards, and the second chuck 23 can clamp and fix the material. And when it is necessary to remove the material, the screw 12 is rotated in the reverse direction to make the first chuck 14 move inwards. When the first chuck 14 moves inwards, it does not exert an outward force on the movable tube 24. Under the elastic force of the telescopic spring 26, the retaining ring 25 is driven to move inwards. The retaining ring 25 moves inwards to drive the movable tube 24 to move inwards, so that the second chuck 23 moves inwards, and the material can be removed.

[0044] Please refer to Figure 4 As shown, on the basis of the above embodiment, this embodiment further includes:

[0045] A fixing component, which includes a chute 31, a slider 32, a fixing block 33, a movable rod 34, a baffle 35 and a fixing nut 36;

[0046] The chute 31 is opened at the inner bottom end of the base 21. The slider 32 is slidably connected to the inside of the chute 31. The fixing block 33 is fixedly connected to the bottom end of the slider 32. The movable rod 34 is fixedly connected to the outer side of the fixing block 33. The baffle 35 is fixedly connected to the outer end of the movable rod 34. The fixing nut 36 is threadedly connected to the outer surface of the movable rod 34;

[0047] The chute 31 is used to guide the slider 32. The slider 32 is used to support the fixing block 33. The fixing block 33 is used to support the movable rod 34. The movable rod 34 is used to support the fixing block 33. The baffle 35 is used to move the movable rod 34. The fixing nut 36 is used to limit the movable rod 34;

[0048] There is a thread structure on the outer surface of the movable rod 34 relative to the fixing nut 36, and the movable rod 34 passes through the lower end of the base 21 and extends outwards;

[0049] The movable rod 34 can move inside the base 21, and the movement of the movable rod 34 can drive the fixing block 33 to move inside the base 21;

[0050] Working principle: When it is necessary to fix the adjusting component, turn the fixing nut 36 outwards so that the fixing nut 36 does not limit the movable rod 34. Then push the baffle 35, so that the baffle 35 drives the movable rod 34 to move inwards. The movable rod 34 exerts an inward force on the fixing block 33, causing the fixing block 33 and the slider 32 to move inwards along the direction of the chute 31. When the inner side surface of the fixing block 33 is in contact with the outer side surface of the base body 11, turn the fixing nut 36 to fix the movable rod 34 on the base 21, so that the fixing block 33 clamps on the outer surface of the base body 11, and then the adjusting component can be fixed.
