Description

a mechanical gripper

technical field

The utility model relates to the technical field of office supplies, in particular to a mechanical gripper.

Background technique

In the process of production and processing, it is often necessary to use mechanical grippers to clamp and fix objects. For example, the publication number CN216967820U discloses a mechanical gripper for mechanical manufacturing, including a connecting cover, a gripper connector 1, and a gripper connection. The second piece and the two-way screw rod, the two-way screw rod is rotated in the connecting cover, the jaw connecting piece one and the clamping jaw connecting piece two are slidingly set in the connecting cover, and are both sleeved on the two ends of the two-way screw rod through threaded holes. The free ends of jaw connecting piece 1 and jaw connecting piece 2 are equipped with elastic adjustable jaw mechanisms on the sides close to each other. Although the above patents change the clamping force on the item to elastic clamping force, it can be adjusted according to different items. Variable demand, but the above-mentioned patents are not strong enough to clamp the items when clamping the items, which may easily cause the items to fall off, and at the same time cannot clamp objects of different shapes. Therefore, in view of this, for the existing structure And the deficiency is researched and improved, and a mechanical gripper is provided, in order to achieve the purpose of having more practical value.

Further, the surface of the first rubber pad is set in an uneven shape. After the device clamps the object, the first rubber pad is set in an uneven shape, which can increase the frictional force of the first rubber pad. Make the fixing of the object on the device more firm.

Further, the bottom end of the motor is fixedly installed with a first connecting plate, one end of the first connecting plate is fixedly installed on the surface of the base, the weight of the motor is relatively heavy, and if it hangs in the air on the surface of the base, it may cause the motor to fall off. As a result, the device cannot be driven, and the motor is supported through the first connecting plate to prevent it from falling off.

Further, two fixed blocks are fixedly installed on the top of the first connecting plate, and the two fixed blocks are respectively installed on both sides of the motor, and the upper end of the telescopic rod is provided with a fixed plate, and the fixed plate and the fixed block are movably connected by screws on the surfaces close to each other. , when the motor is installed on the first connecting plate, the position of the motor on the first connecting plate is more stable through the combination of the fixing plate and the fixing block.

Further, the bottom end of the fixed plate is fixedly installed with a second rubber pad. When the fixed plate and the fixed block are fixed against each other to fix the motor, the second rubber pad provides a flexible buffer for the contact between the fixed plate and the motor to prevent extrusion Cause damage to the motor. At the same time, after the motor is fixed by the fixing plate, the motor will be embedded in the soft second rubber pad. At this time, the fixing strength of the motor can be improved. When the motor shakes after starting, the second rubber pad It is also possible to filter part of the jitter.

Beneficial effects of the utility model

1. The utility model is equipped with a fixed column, a return spring, a telescopic rod, and a push plate. When in use, a certain number of clamps are combined to make the device adapt to objects of any shape, and to fix irregular objects. Improve the practicality of the device.

2. The utility model is equipped with a second rubber pad. When the fixed plate and the fixed block are fixed against each other to fix the motor, the second rubber pad provides a flexible buffer for the contact between the fixed plate and the motor to prevent damage to the motor caused by extrusion. At the same time, after the fixing plate fixes the motor, the motor will be embedded in the soft second rubber pad. At this time, the fixing strength of the motor can be improved. When the motor shakes after starting, the second rubber pad can also partly Jitter filtering greatly improves the practicability of the device.

Detailed ways

Embodiment one:

A mechanical gripper, comprising;

A driving device, comprising a bidirectional threaded rod 100, a base 101 and a motor 103;

The fixture mechanism includes a splint 110, the number of the splint 110 is two, and the bottom ends of the two splints 110 are all movable to install the two-way threaded rod 100, and the other end of the bottom side of the two splints 110 is movable through the guide rod 102, and the two ends of the guide rod 102 It is fixedly installed on the inner wall of the groove of the two-way threaded rod 100, and the two splints 110 are evenly fixed on the surfaces close to each other. There are a certain number of fixed columns 111. The openings at both ends of the fixed columns 111 are different in size. On the surface of 110, a back spring 112 is movably installed inside the large opening of the fixed column 111, one end of the back spring 112 is fixedly installed on the surface of the two-way threaded rod 100, and the other end of the back spring 112 is all fixedly installed with a telescopic rod 113, and the telescopic rod 113 is all movable Going deep into the opening of the fixed post 111, the diameter of one end of the telescopic rod 113 in the fixed post 111 is larger than the diameter of the smaller end of the fixed post 111 opening, and the other end of the telescopic rod 113 is fixedly equipped with a push plate 114.
