Description

Technical Field

[0001] The utility model relates to the technical field of mechanical arms, in particular to a mechanical arm clamp. Background Art

[0002] A robotic arm, also known as a mechanical arm, is the most widely used automated mechanical device in the field of robotics technology. It has good use value in industrial manufacturing, medical treatment, semiconductor manufacturing and other fields. The robotic arm receives instructions and accurately locates a point in three-dimensional space to perform operations. Currently, the most widely used is the six-axis robotic arm, which can not only carry objects, but also rotate or flip objects at an angle.

[0003] In the existing application of robotic arms, most of them are used to grab and transfer the processed and produced items through the robotic arms. Therefore, a clamp is installed at the front end of the robotic arm to clamp the items. Conventional robotic arm clamps are mostly two oppositely arranged clamps that rotate relative to each other under the transmission of two gears to clamp the items. When such clamps are used, the expansion angle of the two clamps is limited, and when clamping items, the two clamps need to maintain an acute angle for easy force application. This leads to great limitations in the operation of the clamp for items of different sizes, and it cannot adapt to the transfer of more items of different sizes. To this end, we propose a robotic arm clamp to solve the above problems. Utility Model Content

[0004] In view of the drawback of the limited use range of existing manipulator clamps, the utility model provides a manipulator clamp having the advantage of being able to freely adjust the distance between the clamp plates, thereby solving the problems raised in the above-mentioned background technology.

[0009] Preferably, the bottom surface of each clamping plate is wrapped with an anti-slip elastic rubber sleeve.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figures 1 to 3 The utility model provides a technical solution: a manipulator clamp, comprising a U-shaped plate 1, arc plates 2 are arranged on both sides of the U-shaped plate 1, the two arc plates 2 are arranged opposite to each other, and support plates 3 are installed at both ends of the arc plates 2, the support plates 3 are fan-shaped plates arranged coaxially with the arc plates 2, arc gears 4 are coaxially installed on the outer side of the support plates 3, and the two arc gears 4 are meshed. The clamp allows the two arc plates 2 to rotate relatively synchronously through the meshing of the two arc gears 4.

[0019] Clamps 7 are symmetrically arranged on both sides of the U-shaped plate 1. Clamps 7 are L-shaped plates with an inclined bottom. An electric push rod 6 is vertically installed on one side of the clamps 7 close to the arc plate 2. The electric push rod 6 is arranged along the radial length direction of the arc plate 2, and the other end of the electric push rod 6 is fixedly connected to the arc plate 2. Rotating rods 5 are installed on both sides of the electric push rod 6. The other end of the rotating rod 5 is rotatably connected to the inner wall of the U-shaped plate 1, and the rotating rod 5 is fixedly penetrated through the support plate 3. A driving mechanism is installed on one end of one rotating rod 5 away from the electric push rod 6. When the manipulator clamp is in use, the driving mechanism drives the rotating rod 5 to rotate, so that the two arc plates 2 rotate relative to each other, thereby controlling the opening and closing of the two clamps 7, and realizing the clamping of the object by the clamp. When the volume of the object to be clamped is too large or too small, the operator can control the electric push rod 6 to drive the clamp 7 to move away from or approach the inner side of the arc plate 2 before use, thereby adjusting the distance between the two clamps 7, so that the clamp is adapted to the volume of the object, which is convenient for the use of the clamp.

[0020] Specifically, during the actual use of the clamp, a flange 13 is installed on the top of the U-shaped plate 1, and the clamp can be fixed to a mechanical arm (such as Figure 3 At the position indicated by the middle arrow A), the distance between the two clamps 7 is adjusted according to the size of the object to be used before use, and then the operator controls the mechanical arm to clamp the object to realize the transfer and movement operation of the object.

[0021] Furthermore, in order to enhance the stress strength of the clamping plate 7 and the movement stability of the clamping plate 7, support tubes 14 are provided in parallel on both sides of each electric push rod 6, one end of the support tube 14 is fixed to the arc plate 2, and a guide rod 15 is accommodated inside the other end of the support tube 14, the guide rod 15 is fixed to the clamping plate 7, and the support tube 14 is fixedly connected to the rotating rod 5. When the electric push rod 6 drives the clamping plate 7 to move, the guide rod 15 will be correspondingly extended and retracted in the support tube 14, so that an additional support function is provided between the clamping plate 7 and the arc plate 2 through the connection between the guide rod 15 and the support tube 14, thereby improving the stress strength of the clamping plate 7.

[0022] Furthermore, if Figure 1 As shown, a plurality of strip grooves 9 are formed on the top of each clamp plate 7, and the strip grooves 9 are arranged equidistantly along the length direction of the rotating rod 5, and a plurality of reinforcing rods 10 are installed inside the strip grooves 9. While ensuring the strength of the clamp plate 7, the manufacturing cost of the clamp is saved.

[0023] Furthermore, in order to prevent the two clamping plates 7 from slipping when clamping the objects, the bottom surface of each clamping plate 7 is wrapped with an anti-slip elastic rubber sleeve 8. When the clamping plates 7 clamp the objects, the elastic rubber sleeve 8 contacts the objects, increasing the friction between the clamping plates 7 and the objects, thereby improving the clamping effect of the clamp on the objects.

[0024] Furthermore, if Figure 1 and Figure 2 As shown, the driving mechanism includes a housing 11, which is mounted on the side of the U-shaped plate 1, and a belt transmission device 16 is provided inside the housing 11, one of the pulleys of the belt transmission device 16 is coaxially fixed on the rotating rod 5, and a driving motor 12 is coaxially mounted on the other pulley of the belt transmission device 16, and the driving motor 12 is fixed on the top of the U-shaped plate 1. The clamp provides power for the rotation of the two clamping plates 7 through the operation of the driving motor 12.
