[0002] Mechanical grippers are widely used in the manufacturing industry for picking, placing and transporting products, including machinery, equipment, robots and other industries. Most of the existing mechanical grippers are only compatible with one shape. Due to the wide variety of shapes and sizes of objects, the length of the gripping arm needs to be redesigned according to the shapes and sizes of different objects. This requires more manpower, material and financial resources, and the power transmission parts and joints are mostly exposed, which cannot cope with harsh working environments such as severe dust. Summary of the invention

[0009] Furthermore, the cylinder body of the rotating cylinder is fixedly connected to the rear end surface of the circular flange.

[0010] Furthermore, the driving transmission mechanism includes a driving gear, a driven gear, and threaded guide shafts at both ends. The driving gear is fixedly connected to the cylinder rotating flange through a driving gear flange. Multiple driven gears are meshed and connected to the driving gear and are evenly distributed along the outer circumference of the driving gear. Each driven gear is connected to a circular flange through threaded guide shafts at both ends and a bearing seat; the upper ends of the threaded guide shafts at both ends are fixedly connected to one end of the arc-shaped clamping arm.

[0011] Furthermore, the other end of the arc-shaped clamping arm is fixedly connected to a clamping straight rod.

[0012] Furthermore, the clamping straight rod is covered with a silicone cushioning sleeve to prevent damage to the object.

[0013] Furthermore, the rotation angle of the rotary cylinder is adjustable within the range of 0° to 180°.

[0014] Furthermore, the drive transmission mechanism is provided with a dust cover outside to seal the drive transmission mechanism.

[0015] Furthermore, the rotating and retractable clamping mechanical claw is used for round or square objects, and can be clamped and placed from the inside or outside of the object.

[0016] The beneficial effects of the present invention are: compared with the traditional mechanical gripper, a dustproof sealing structure is added, the wear of the transmission system is reduced, the environmental adaptability of the mechanical gripper is enhanced, the stability and service life of the mechanical gripper are improved, and the mechanical gripper can be compatible with square and round objects of different sizes, which greatly reduces the replacement frequency of the mechanical gripper.

DETAILED DESCRIPTION

[0025] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0026] like Figures 1 to 7 As shown, a rotating and retractable clamping mechanical claw includes a soft silicone buffer sleeve 01, a clamping straight rod 02, an arc-shaped clamping arm 03, a dust cover 04, a circular flange 05, a rotating cylinder body 06, a driving gear flange 09, a threaded guide shaft 10 at both ends, a driven gear 11, a driving gear 12, a rotating cylinder rotating flange 13, etc.

[0027] The driving gear 12 is fixedly connected to the cylinder rotating flange 13 through the driving gear flange 09, and the driven gear 11 is fixedly connected to the circular flange 05 through the threaded guide shafts 10 at both ends, the bearing seat 08 and the arc-shaped clamping arm 03. The clamping straight rod 02 is fixed to the arc-shaped clamping arm 03, and the outside is covered with a silicone buffer sleeve 01 to prevent damage to the items.

[0028] When the positive air pressure 07 is turned on, the rotating flange 13 on the rotating cylinder 06 rotates, and the rotation angle is adjustable within the range of 0°-180°. The rotating flange 13 then drives the internal driving gear 12 to rotate through the driving gear flange 09. The driving gear 12 meshes with the driven gear 11, and drives the four driven gears 11 to rotate synchronously during rotation. The four driven gears 11 simultaneously drive the four arc-shaped clamping arms 03 to swing synchronously. The clamping straight rod 02 is fixed to the arc-shaped clamping arm 03. The clamping straight rod 02 is covered with a soft silicone buffer sleeve 01 to prevent damage to the object. The clamping straight rod 02 swings with the arc-shaped clamping arm 03, so that the four clamping straight rods 02 can rotate inwards and shrink synchronously or rotate outwards and expand synchronously, so that the mechanical claw can adapt to round or square objects at the same time and clamp and take and place from the inside or outside of the object. The dust cover 04 can seal the internal transmission mechanism, so that a mechanical claw is compatible with multiple products, realizes multiple uses of one claw, and can cope with harsh working environments. This improves the stability of the equipment, reduces the frequency of mechanical claw replacement, and saves manpower, financial resources, and material resources.

[0029] The rotating retractable clamping mechanical claw of the present invention is a multifunctional mechanical claw with a simple structure, stable performance, strong environmental adaptability and high compatibility, which is powered by air pressure and uses gears for transmission. When the mechanical claw is working, the external air pressure enters the interior of the rotating cylinder through the air inlet and outlet 107 and the air inlet and outlet 2 14, pushing the rotating flange 13 to rotate forward or reverse, and the rotation angle is adjustable within the range of 0°-180°. The rotating flange 13 drives the driving gear 12 to rotate forward or reverse through the driving gear flange 09, and the driving gear 12 meshes with the four driven gears 11 and rotates synchronously. The silicone cushion sleeve 01, the clamping straight rod 02, the arc-shaped clamping arm 03 and the driven gear 11 are fixed as a whole. The driven gear 11 is connected through the threaded guide shaft 10 at both ends, the bearing seat 08 and the disc flange 05. The driven gear 11 can rotate around the threaded guide shaft 10 at both ends, so that when the air inlet and outlet 1 07 is inlet and the air inlet and outlet 2 14 is outlet, the four arc-shaped clamping arms 03 swing inward and contract at the same time. When the air inlet and outlet 1 07 is outlet and the air inlet and outlet 2 14 is inlet, the four arc-shaped clamping arms 03 swing outward and expand at the same time. A driving path is provided, specifically, the driving gear drives the driven gear to rotate, and the driven gear is fixedly connected to the threaded guide shaft, thereby driving the threaded guide shaft to rotate, and further driving the arc-shaped clamping arm to move. The bearing seat is arranged on the side of the circular flange close to the driven gear, so that the dust cover can seal the gear while also sealing the corresponding bearing seat and guide shaft to prevent dust. The seal of the dust cover 04 can prevent the harsh working environment from damaging the bearings and gears in the internal transmission mechanism, so as to achieve the purpose of improving the stability and adaptability of the equipment.

[0030] Although the specific implementations of the present invention have been described in detail with reference to the embodiments of the present invention, those skilled in the art may make reasonable optimizations and improvements without departing from the spirit and principles of the present invention and the scope of the foregoing disclosure, drawings and claims.
